Some codes muscle relaxer 800 mg order lioresal with amex, such as 43220 (balloon dilation) back spasms 7 weeks pregnant lioresal 10mg generic, do not include imaging guidance (74360) spasms of the esophagus cheap 25 mg lioresal overnight delivery, whereas other codes include the guidance xanax muscle relaxant dosage buy generic lioresal 10 mg line, such as 43231 (diagnostic esophagoscopy with endoscopic ultrasound examination) muscle relaxant pregnancy generic 25mg lioresal mastercard. Note that many codes include conscious sedation as a part of the service as indicated by the bullseye symbol to the left of the code muscle relaxant metabolism order generic lioresal canada. The Incision codes include both cervical approach (43020) and thoracic approach (43045) for removal of a foreign body as illustrated in. It is important to confirm the approach used when coding removal of a foreign body from the esophagus. The Excision codes (43100-43135) also include various approaches in the code description, such as cervical, thoracic, and abdominal. If a lesion is removed from the esophagus, report the service with 43100 (cervical) or 43101 (thoracic or abdominal), depending on the approach used. If a partial, near total, or total removal (wide excision) of the esophagus is performed with total removal of the larynx, the service may or may not include extensive (radical) neck dissection. These removal services are reported with 43107, 43116 (with graft), 43124, or 31360 (total laryngectomy from the Respiratory System). Code 43191 is a transoral esophagoscopy by means of a rigid scope and 43200 is by means of a flexible scope. Both are diagnostic and include the collection of specimen(s) by brushing or washing. Both are categorized as separate procedures and only reported if no more major esophageal procedure was performed. Medical necessity for a diagnostic procedure must be documented in the medical record. For example, the signs and/or symptoms demonstrate the medical necessity of the service. If the service has 0 global days, this means the procedure includes all preoperative and postoperative care related to performing the procedure on the day of the procedure; but before or after the day of the procedure, any services related to the procedure are reported separately. The diagnostic esophagoscopy is bundled into all endoscopy procedures reported with 43180-43233 and 43235-43259, 43210. Codes 43192 and 43201 describe transoral esophagoscopy with submucosal injections of any substance. You must report the substance injected; for example, botulinum toxin (J0585) to treat esophageal spasms. As with all codes, the diagnosis must support the medical necessity of the esophagoscopy. For example, some diagnoses that would support the medical necessity of the esophagoscopy would be K22. Codes 43194 or 43215 report a transoral esophagoscopy for removal of foreign body(s). The medical necessity of this procedure would be demonstrated by a diagnosis code such as T18. If radiology is used during the procedure, report the radiology service with 74235 (Removal of foreign body(s), esophageal, with use of balloon catheter, radiological supervision, and interpretation). The removal or ablation of esophageal polyp(s), tumor(s), or other lesion(s) are reported with 43216 or 43217. Hot biopsy forceps use high frequency electrical current to remove and cauterize in one maneuver. The following dilation procedures may use fluoroscopy (74360) but do not include endoscopy: 43450, dilation of the esophagus, by unguided sound or bougie (cylinder), single or multiple passes 43453, dilation of the esophagus, over guidewire 43460, esophagogastric tamponade, with balloon (Sengstaken type) (A balloon is placed into the esophagus and inflated to stop bleeding. Fluid, usually saline, is injected around the polyp and the fluid elevates the polyp to allow for easier excision. When a submucosal injection is performed, report the service based on the delivery method. During this procedure, a special suturing system is inserted through the scope, the physician then places a series of stitches in the esophagogastric junction, essentially pleating the sphincter to prevent the backflow of stomach acid into the esophagus. The medical necessity of the procedure would be demonstrated with a diagnosis code, such as K21. The services are performed during the same endoscopic session and are reported as: 43245 (Esophagogastroduodenoscopy, flexible, transoral; with dilation of gastric/duodenal stricture(s) [e. She has lost 10 pounds in the last 4 months because she is hesitant to eat for fear of choking. Reporting multiple procedures on the same day and by the same provider is allowed (aside from E/M services). Any additional procedures to the primary procedure would be reported with modifier -51. However, if a biopsy was performed on two different sites, modifier -59 would be appended to the additional biopsy site. Through the endoscope, the physician can visualize the inside of the stomach and duodenum, and injects dye into the ducts of the biliary tree and pancreas to be viewed on x-ray. The scope is advanced through the esophagus, into the stomach, to the duodenal papilla (papilla of Vater), and contrast is then injected to visualize the bile ducts and biliary tract, including the gallbladder. Assignment of these codes is based on purpose of the procedure as diagnostic or therapeutic. During the procedure, the physician may view the common bile duct or the entire biliary tract. The procedure may be with or without the collection of specimen(s) by brushing or washing, which is not reported separately because collection is included in the code description. If there is no definitive diagnosis documented in the medical record, assign code(s) for the documented signs and symptoms. C O D I N G S H O T There are times when the insertion for visualization cannot be accomplished, due to a variety of factors. Surgical laparoscopy is a procedure to examine the organs of the abdominal cavity and always includes diagnostic laparoscopy. A similar procedure is utilized to view the organs of the pelvis (gynecologic laparoscopy or pelviscopy). Other procedures are performed by means of a scope, such as 43653 (laparoscopic gastrostomy). Be certain to identify the method used to perform the procedure before assigning a code. Gastric bypass surgery is performed on patients who are morbidly obese with the outcome of decreasing the size of the stomach and/or intestines to aid with weight loss. The Roux-en-Y term is used in several code descriptions, such as 43621 (total gastrectomy with Roux-en-Y reconstruction) and 43644 (laparoscopic gastric restriction, with gastric bypass and Roux-en-Y gastroenterostomy). For an open procedure, a 6to 9-inch incision is made in the abdomen to gain access to the stomach and intestines. For a laparoscopic procedure about six access ports are established measuring about 1fi4 to 1fi2 inch each in diameter through which the surgical instruments are inserted. The laparoscopic procedures are much less invasive and decrease the time the patient spends in the hospital, recovery time, and complications. Bariatric Surgery codes 43770-43775 also report procedures performed for gastric restrictive procedures that are accomplished by placing a restrictive device around the stomach to decrease its functional size. The band is adjustable because the band is hollow and contains a tube that can be inflated with fluid. After surgery, fluid is gradually inserted into the tube through a subcutaneous port (just beneath the skin) with a syringe. The physician can adjust the amount of fluid in the tube and thereby adjust the amount of food that can pass through the banded area. The procedure may be performed on an outpatient basis and is reversible by removal of the banding apparatus. Medicare released its new policy for bariatric surgery in February of 2009, which covers open and laparoscopic Roux-en-Y gastric bypass, laparoscopic adjustable gastric banding, and open and laparoscopic biliopancreatic diversion with duodenal switch. Bariatric surgery is available for any Medicare beneficiary with a body mass index of 35 or greater with at least one comorbidity related to obesity. Intestines (except rectum) the large intestine is about 5 feet long with a wider diameter than the small intestine. The Intestine codes 44005-44799 exclude codes to report services for the anus and rectum. Colostomies (creation of an artificial opening) are always bundled into a more major procedure unless the code specifically states to report the colostomy separately. For example, code 44141 is a partial colectomy and includes establishment of a colostomy. Many intestinal procedures are performed through endoscopes (such as the gastroscopy in. Endoscope codes are available for procedures depending on how far down (through the mouth) or up (through the anus) the scope is passed. The code selection varies according to the procedure performed and includes the sites the scope passed through to accomplish the procedure. For example, if a flexible scope is passed to the esophagus only, the code would be chosen from the endoscopy codes 43180-43233. Once the anatomic site of the endoscope procedure is correctly identified, the surgical procedure(s) performed guides the selection of the code. C O D I N G S H O T To choose the correct endoscopy, identify the farthest extent to which the scope was passed and then the procedure(s) performed. Resection of the intestine means taking out a portion of the intestine and either joining the remaining ends (anastomosis) directly or developing an artificial opening (exteriorizing) through the abdominal wall. The artificial opening (stoma) allows for the removal of body waste products. The type of anastomosis or exteriorization depends on the medical condition of the patient and on the amount of intestine (large or small) that has to be removed. Some patients have temporary exteriorization for the length of time it takes the remaining intestine to heal and begin to perform the necessary functions. Other patients have permanent exteriorization because too much of the intestine has been removed to allow for adequate functioning. To assign the correct code, identify the correct anatomic site from which the ostomy originated, as well as the procedure used to establish the ostomy. If only the exploratory laparotomy is performed, it is appropriate to report the service with an exploratory laparotomy code, such as 49000. However, if the exploratory procedure progressed to a more definitive surgical treatment (such as an appendectomy), only the definitive treatment (appendectomy) is reported. Removal of the omphalomesenteric duct refers to the embryonic passage that connects an egg sac to the intestine and is included in the code description of 44800. Because the abdomen is already open to the view of the surgeon, the incidental appendectomy (44950) does not add to the complexity of the procedure and is not reported separately. If, however, during another major abdominal procedure, the surgeon removes the appendix due to a medically necessary reason, the service is reported with 44955. Colon and rectum Colon and Rectum procedures are reported with codes from the 45000-45999 range. These procedures involve the colon and rectum and employ techniques such as incision, excision, and destruction. If any of the listed procedures were performed, they are bundled in the main code (45126) and not reported separately. Endoscopy (proctosigmoidoscopy, sigmoidoscopy, and colonoscopy) Rectal endoscopic procedures are frequently performed and include proctosigmoidoscopy, sigmoidoscopy, and colonoscopy. Endoscopic examination of the rectum (proct/o = rectum) and the sigmoid colon (45300-45327). Code 45300 describes a rigid proctosigmoidoscopy, diagnostic, with or without collection of specimen(s) by brushing or washing (separate procedure). Do not assign 45300 when reported with codes 45303-45327, because these codes report surgical procedures, so the diagnostic service of 45300 is bundled into the surgical procedure. Endoscopic examination of the sigmoid colon may include the descending colon (45330-45350). A sigmoidoscopy is the examination of the entire rectum and sigmoid colon and may include examination of a portion of the descending colon but stops before reaching the splenic flexure (the turn beneath the spleen that connects the descending to the transverse colon). Code 45330 describes a flexible diagnostic sigmoidoscopy that includes the collection of specimen(s) by brushing or washing (separate procedure). Do not code 45330 when also reporting 4533145350 because they are surgical procedures and the diagnostic procedure (45330) is always included in the surgical procedure. If a definitive diagnosis has not been documented, report the documented signs/symptoms. Endoscopic examination of the colon from rectum to cecum is reported with codes from the 45378-45398 range. The diagnostic colonoscopy codes are divided based on the extent and the purpose of the procedure. The diagnostic stand-alone codes 45300, 45330, and 45378 each have a list of indented procedure codes based on the purpose of the procedure (such as biopsy, foreign body removal, ablation, control of bleeding, etc.

Such would be the case with rabbits spasms tamil meaning buy lioresal no prescription, which do not contaminate pastures to any significant extent infantile spasms 9 month old discount lioresal 10mg with amex. Man is infected mainly by eating watercress (Nasturtium officinale) infested with metacercariae spasms that cause shortness of breath 10 mg lioresal fast delivery. In France spasms cell cancer buy cheap lioresal on-line, where watercress is a popular salad ingredient (10 muscle relaxant dosage flexeril 25 mg lioresal with amex,000 tons are consumed each year) spasms with fever order lioresal 25 mg without a prescription, human infection is more frequent than in other European countries. Sometimes raw lettuce and other contaminated plants that are eaten raw can also be a source of infection, as can water from irrigation ditches or other receptacles. Alfalfa juice has also been implicated in places where people drink this beverage. The infection cycle in nature is maintained between animals (especially sheep and cattle) and snails of the family Lymnaeidae. The epidemiological picture of human fascioliasis appears to have changed in recent years. In the last two decades, the number of human cases has increased in places that are geographically unrelated to areas in which the animal disease is endemic. Diagnosis: the disease is suspected on the basis of clinical manifestations (painful and febrile hepatomegaly coupled with eosinophilia) and is confirmed by the finding of characteristic eggs in feces. During the acute phase, no eggs can be seen because the parasites have not yet matured, and therefore immunologic tests are often used. In this phase, it is important to distinguish fascioliasis from acute hepatitides due to other causes. Epidemiologic antecedents (abundance of cases in the area, custom of eating watercress) and the presence of peripheral eosinophilia assist in identification. In animals, the diagnosis of acute fascioliasis is often made at autopsy based on observation of hepatic lesions and the presence of immature parasites. Ultrasound does not show the migrating parasites during the acute phase and reveals only 50% of the patent cases (Fawzy et al. In a series comparing the two approaches, coprologic observation revealed 68% of the cases, whereas the study of the bile aspirate identified 98% of the cases. In Latin America, there have been cases of unnecessary and prolonged hospitalization of hepatic patients, and sometimes even surgical interventions have been performed, because differential diagnosis failed to take fascioliasis into account. The prepatent period of fascioliasis lasts for so long (more than two months in humans), that it is one of the few parasitic diseases in which immunology is useful for diagnosis. The search for appropriate antigens has improved the specificity and sensitivity of these tests, but there are still cross-reactions, especially with schistosomiasis. Early diagnosis of fascioliasis makes it possible to start treatment before liver damage is too far advanced. Control: Individuals can prevent fascioliasis by not eating raw watercress of wild or unknown origin. Watercress can be cultivated under controlled conditions that prevent access by animals, and therefore fecal contamination, as well as infestation by snails. However, most watercress sold in markets has been gathered by persons who are unaware of the sanitary conditions under which the plant was grown. A modern plan for the control of animal fascioliasis, which would ultimately forestall human infection, would include: a) preventing the consumption of metacercariae, b) strategically administering fasciolicides to the definitive hosts, and c) eliminating the intermediate hosts. Preventing the ingestion of Fasciola metacercariae involves fencing in contaminated areas, which is difficult, expensive, and not very effective. The strategic administration of fasciolicides, unlike curative treatment, is aimed at interrupting the life cycle of the parasite by treating animals according to a regimen that will prevent the initial infection, the formation of eggs, and, finally, contamination of the environment. There are now highly sophisticated methods for calculating the best time to administer such treatments (Yilma and Malone, 1998). Previously, some of the chemical compounds against Fasciola killed only the adult or juvenile specimens, but now broad-spectrum treatments are available. The ecologic approach consists of modifying the environment to interrupt the life cycle of the snails. Drainage of the land, where this is technically and economically feasible, is the one permanent way to control or eliminate the mollusks. It is also beneficial to smooth the banks of watercourses and remove marginal vegetation to prevent the formation of backwater pools where the snails flourish. This approach is very costly and therefore cannot be applied on a large scale on most livestock-raising establishments in the developing countries. In temperate climates, molluscicides should be applied for the first time in spring, when the snails are beginning to reproduce. Application can be repeated in mid-summer to kill the snails before the cercariae are released, and again in autumn, to reduce the population going into hibernation. In climates with only two seasons (dry and rainy), molluscicides should be applied at the beginning and end of the rainy season. Many traditional molluscicides are inactivated by organic materials and elevated pH levels. The biologic approach involves enlisting the natural enemies of the snails that serve as intermediate hosts. Although there are many known competitors, predators, and parasites of snails, this subject has not been fully studied. Vaccination against Fasciola might be an appropriate control method, but most researchers have found that sheep do not produce significant protective immunity against this parasite.

The miracidium emerges from the mature egg and penetrates small planorbid snails, mainly of the genera Gyraulus, Segmentina, Helicorbis, Hippeutis, and Polypylis. In mollusks, the miracidium passes through the sporocyst stage and two generations of rediae. The second generation of rediae gives rise to large numbers of cercariae, which emerge from the snails and encyst as metacercariae on aquatic plants. The studies in China have found that almost 4% of the metacercariae encyst in the water. The definitive hosts, humans or swine, become infected by consuming aquatic plants or water with metacercariae. In the intestine, the metacercaria is released from its envelope, and after about three months, the parasite reaches maturity and reinitiates the cycle by oviposition. Geographic Distribution and Occurrence: the infection is common in southeast Asia (Waikagul, 1991). The parasitosis occurs in Bangladesh, central and southern China, India, the Indochina peninsula, Indonesia, and Taiwan. Cases have also been reported, many of them among immigrants, in the Philippines, Japan, and several Western countries. Prevalence is very variable but generally low in humans and is thought to be higher in the areas where swine are raised. In several areas of Chekiang and Kiangsi Provinces, China, the prevalence can be as high as 85%; in contrast, in other areas of the country infection rates ranging from less than 1% to 5% are found. Approximately half of all human infections are believed to occur in China (Malek, 1980). A study conducted in an endemic area of Thailand found that the prevalence of infection in humans was similar to that of the swine population. In some areas of China with high rates of human infection, the parasitosis in swine has not been confirmed. The Disease in Man and Animals: this parasite produces few or no symptoms in most hosts. Perhaps because it is the largest trematode affecting man, traumatic, toxic, and obstructive effects have been attributed to it, with epigastric pain, nausea, diarrhea, undigested food in the feces, and edemas of the face, abdomen, and legs. Yet a clinical study of a group of mostly young persons in Thailand who were eliminating F. The severe disease described in the literature seemingly corresponds to cases with a large parasite burden (Liu and Harinasuta, 1996). By and large, the health of the pigs is not affected, and the symptoms of the disease occur only in cases of massive parasitosis. Source of Infection and Mode of Transmission: the source of infection for humans and swine is aquatic plants and water containing metacercariae. Epidemiological research in China suggests that between 10% and 13% of persons and from 35% to 40% of swine are infected more from drinking water contaminated with metacercariae than from eating plants. Endemic areas offer the ecological conditions necessary for the growth of both the intermediate hosts and the edible aquatic plants. In central Thailand, these conditions occur in flooded fields, where edible aquatic plants are cultivated near dwellings. These fields receive human excreta directly from the houses, which are built on pillars. The hosts are the snails Hippeutis umbilicalis and Segmentina trochoideus in Bangladesh, in addition to Polypylis hemisphaerula in China, Thailand, and Taiwan (Gilman et al. It has also been found that Helicorbis umbilicalis is an intermediate host in Laos (Ditrich et al. Certain parts of these plants are eaten raw, and the teeth and lips are often used to peel the pods and bulbs. In general, the prevalence of human infection is higher in areas where the aquatic plants are cultivated and lower in distant towns, since metacercariae attached to the plants are not resistant to desiccation when some time elapses between harvest and marketing. The pig is considered a reservoir of the parasite that could maintain the infection in the human population even if the sanitary elimination of human excreta were achieved. In Muslim countries, such as Bangladesh, swine do not play any role as a reservoir; man is practically the only reservoir and only source of infection for snails (Gilman et al. The infection can be imported by patients into regions where intermediate hosts exist; one study found that 3 of 93 Thai workers in Israel were infected by F. The eggs are very similar to those of Fasciola gigantica and Fasciola hepatica; experts say that the eggs of F. There are no reports on attempts at immunological diagnosis, but the parasite has shown crossreactions in tests for Fasciola hepatica, the larva of Taenia solium, and Trichinella spiralis. Control: the simplest way to prevent human parasitosis is to refrain from eating fresh or raw aquatic plants, peeling them with the teeth, or drinking water from contaminated areas, but this recommendation requires changing a habit, which is difficult to achieve. Studies conducted in China have shown that immersing contaminated plants in boiling water for 1 to 2 minutes is sufficient to kill the parasite. Other measures to combat the parasitosis, in addition to health education, are to use molluscicides, to treat the affected population, to treat the human excreta in septic tanks or with quicklime, to prevent the fertilization of fields with human feces, and to prohibit swine raising in endemic areas.

Agenesis of the corpus callosum may be either complete or partial (usually affecting the posterior part) muscle relaxant lodine buy 10mg lioresal mastercard. Etiology Agenesis of the corpus callosum may be due to maldevelopment or secondary to a destructive lesion spasms near temple discount 25 mg lioresal with mastercard. It is commonly associated with chromosomal abnormalities (usually trisomies 18 spasms in legs buy cheap lioresal 25mg, 13 and 8) and more than 100 genetic syndromes spasms hamstring order lioresal in india. Agenesis of the corpus callosum is demonstrated in the mid-coronal and mid-sagittal views muscle spasms zinc cheap lioresal line, which may require vaginal sonography muscle relaxant drugs flexeril purchase lioresal with a mastercard. In about 90% of those with apparently isolated agenesis of the corpus callosum development is normal. The condition is classified into (a) Dandy-Walker malformation (complete or partial agenesis of the cerebellar vermis and enlarged posterior fossa), (b) Dandy-Walker variant (partial agenesis of the cerebellar vermis without enlargement of the posterior fossa), and (c) mega-cisterna magna (normal vermis and fourth ventricle). Etiology the Dandy-Walker complex is a non-specific end-point of chromosomal abnormalities (usually trisomy 18 or 13 and triploidy), more than 50 genetic syndromes, congenital infection or teratogens such as warfarin, but it can also be an isolated finding. Diagnosis Ultrasonographically, the contents of the posterior fossa are visualized through a transverse suboccipito-bregmatic section of the fetal head. In the Dandy-Walker malformation there is cystic dilatation of the fourth ventricle with partial or complete agenesis of the vermis; in more than 50% of the cases there is associated hydrocephalus and other extracranial defects. Enlarged cisterna magna is diagnosed if the vertical distance from the vermis to the inner border of the skull is more than 10 mm. Prenatal diagnosis of isolated partial agenesis of the vermis is difficult and a false diagnosis can be made prior to 18 weeks gestation, when the formation of the vermis is incomplete and anytime in gestation if the angle of insonation is too steep. Prognosis Dandy-Walker malformation is associated with a high postnatal mortality (about 20%) and a high incidence (more than 50%) of impaired intellectual and neurological development. Experience with apparently isolated partial agenesis of the vermis or enlarged cisterna magna is limited and the prognosis for these conditions is uncertain. Etiology this may result from chromosomal and genetic abnormalities, fetal hypoxia, congenital infection, and exposure to radiation or other teratogens, such maternal anticoagulation with warfarin. It is commonly found in the presence of other brain abnormalities, such as encephalocele or holoprosencephaly. Diagnosis the diagnosis is made by the demonstration of brain abnormalities, such as holoprosencephaly. In cases with apparently isolated microcephaly it is necessary to demonstrate progressive decrease in the head to abdomen circumference ratio to below the 1st centile with advancing gestation. In microcephaly there is a typical disproportion between the size of the skull and the face. The brain is small, with the cerebral hemispheres affected to a greater extent than the midbrain and posterior fossa. Prognosis this depends on the underlying cause, but in more than 50% of cases there is severe mental retardation. However, it may also be the consequence of genetic syndromes, such as Beckwith-Wiedemann syndrome, achondroplasia, neurofibromatosis, and tuberous sclerosis. Diagnosis the diagnosis is made by the demonstration of a head to abdomen circumference ratio above the 99th centile without evidence of hydrocephalus or intracranial masses. Unilateral megalencephaly is characterized by macrocrania, a shift in the midline echo, borderline enlargement of the lateral ventricle and atypical gyri of the affected hemisphere. Unilateral megalencephaly is associated with severe mental retardation and untreatable seizures. In hydranencephaly there is absence of the cerebral hemispheres with preservation of the mid-brain and cerebellum. In porencephaly there are cystic cavities within the brain that usually communicate with the ventricular system, the subarachnoid space or both. Schizencephaly is associated with clefts in the fetal brain connecting the lateral ventricles with the subarachnoid space. Etiology Hydranencephaly is a sporadic abnormality that may result from widespread vascular occlusion in the distribution of the internal carotid arteries, prolonged severe hydrocephalus, or an overwhelming infection such as toxoplasmosis or cytomegalovirus. Porencephaly may be caused by infarction of the cerebral arteries or hemorrhage into the brain parenchyma. Schizencephaly may be a primary disorder of brain development or it may be due to bilateral occlusion of the middle cerebral arteries. Diagnosis Complete absence of echoes from the anterior and middle fossae distinguishes hydranencephaly from severe hydrocephalus in which a thin rim of remaining cortex and the midline echo can always be identified. In porencephaly there is one or more cystic areas in the cerebral cortex, which usually communicates with the ventricle; the differential diagnosis is from intracranial cysts (arachnoid, glioependymal), that are usually found either within the scissurae or in the mid-line and compress the brain. In schizencephaly there are bilateral clefts extending from the lateral ventricles to the subarachnoid space, and is usually associated with absence of the cavum septum pellucidum. Prognosis Hydranencephaly is usually incompatible with survival beyond early infancy. The prognosis in porencephaly is related to the size and location of the lesion and although there is increased risk of impaired neurodevelopment in some cases development is normal. They occur most frequently in the area of the cerebral fissure and in the midline. Large cysts may cause significant mass effect and the distinction from porencephaly may be difficult. Interhemispheric cysts associated with agenesis of the corpus callosum most likely are not arachnoid cysts, but rather glioependymal cysts. However, a normal intellectual development in the range of 80-90% is reported by most series. Spontaneous remission has been described both in the postnatal as well as in the antenatal period. Glioependymal cysts, that should be suspected in those cases with associated agenesis of the corpus callosum probably reflect a greater degree of derangement in the development of the brain and this may be reflected in a worse outcome. Prevalence Choroid plexus cysts are found in about 2% of fetuses at 20 weeks of gestation but in more than 90% of cases they resolve by 26 weeks. Etiology the choroid plexus is easily visualized from 10 weeks of gestation when it occupies almost the entire hemisphere. Thereafter and until 26 weeks, there is a rapid decrease in both the size of the choroid plexus and of the lateral cerebral ventricle in relation to the hemisphere. Diagnosis the diagnosis is made by the presence of single or multiple cystic areas (greater than 2 mm in diameter) in one or both choroid plexuses. Prognosis They are usually of no pathological significance, but they are associated with an increased risk for trisomy 18 and possibly trisomy 21. In the absence of other markers of trisomy 18 the maternal age-related risk is increased by a factor of 1. Diagnosis the diagnosis is made by the demonstration of a supratentorial mid-line translucent elongated cyst. Prognosis In the neonatal period about 50% of the infants present with heart failure and the rest are asymptomatic. Good results can be achieved by catheterization and embolization of the malformation. Sagittal, transverse and coronal planes are all useful for the evaluation of normal and abnormal anatomy. A mid-sagittal plane allows visualization of the fetal profile, whereas the ears are visualized in parasagittal scans tangential to the calvarium. The coronal planes are probably the most important ones in the evaluation of the integrity of facial anatomy. A series of transverse scans from the top of the head moving caudally allows examination of the forehead, nasal bridge, orbits, nose, upper lip and anterior palate, the tongue within the oral cavity, lower lip and mandible. As a rule of thumb, each orbital diameter is equal in size to the interorbital diameter. In cases of suspected defects measurement of the internal and external orbital diameters may be necessary. As gestation progresses, they migrate toward the mid-line, creating favorable conditions for the development of stereoscopic vision. Hypertelorism is an increased interorbital distance and this can be either an isolated finding or associated with many clinical syndromes or malformations. The most common syndromes with hypertelorism are the median cleft syndrome (hypertelorism, median cleft lip with or without a median cleft of the hard palate and nose, and cranium bifidum occultum), craniosynostoses (including Apert, Crouzon, and Carpenter syndromes), agenesis of the corpus callosum and anterior encephaloceles. Hypertelorism per se results only in cosmetic problems and possible impairment of stereoscopic binocular vision. For severe cases, a number of operative procedures, such as canthoplasty, orbitoplasty, surgical positioning of the eyebrows, and rhinoplasty, have been proposed. The median cleft face syndrome is usually associated with normal intelligence and life span. However, there is a high likelihood of mental retardation when either extracephalic anomalies or an extreme degree of hypertelorism is found. The severity of the cosmetic disturbance should not be underestimated, because this syndrome may be associated with extremely grotesque features. Hypotelorism (stenopia) Hypotelorism (decreased interorbital distance) is almost always found in association with other severe anomalies, such as holoprosencephaly, trigonocephaly, microcephaly, Meckel syndrome, and chromosomal abnormalities. Microphthalmia / anophthalmia Microphthalmia is defined as a decreased size of the eyeball and anophthalmia refers to the absence of the eye; however, the term anophthalmia should be reserved for the pathologist, who must demonstrate not only absence of the eye but also of optic nerves, chiasma, and tracts. Microphthalmia / anophthalmia, which is either unilateral or bilateral, is usually associated with with one of about 25 genetic syndromes. In Goldenhar syndrome (found in about 1 per 5,000 births) there is unilateral anophthalmia, together with ear and facial abnormalities. Prenatal diagnosis is based on the demonstration of decreased ocular diameter and careful examination of the intraorbital anatomy is indicated to identify lens, pupil, and optic nerve. Congenital microphthalmia is frequently associated with visual disorders and with other anomalies. Facial clefts encompass a broad spectrum of severity, ranging from minimal defects, such as a bifid uvula, linear indentation of the lip, or submucous cleft of the soft palate, to large deep defects of the facial bones and soft tissues. The typical cleft lip will appear as a linear defect extending from one side of the lip into the nostril. Cleft palate associated with cleft lip may extend through the alveolar ridge and hard palate, reaching the floor of the nasal cavity or even the floor of the orbit. Isolated cleft palate may include defects of the hard palate, the soft palate, or both. Both cleft lip and palate are unilateral in about 75% of cases and the left side is more often involved than the right side. In about 50% of cases both the lip and palate are defective, in 25% only the lip and in 25% only the palate is involved. Etiology the face is formed by the fusion of four outgrowths of mesenchyme (frontonasal, mandibular and paired maxillary swellings) and facial clefting is caused by failure of fusion of these swellings. Cleft lip with or without cleft palate is usually (more than 80% of cases) an isolated condition, but in 20% of cases it is associated with one of more than 100 genetic syndromes. Isolated cleft palate is a different condition and it is more commonly associated with any one of more than 200 genetic syndromes. All forms of inheritance have been described, including autosomal dominant, autosomal recessive, X-linked dominant and X-linked recessive. Associated anomalies are found in about 50% of patients with isolated cleft palate and in about 15% of those with cleft lip and palate. Chromosomal abnormalities (mainly trisomy 13 and 18) are found in 1-2% of cases and exposure to teratogens (such as antiepileptic drugs) in about 5% of cases. Recurrences are type specific; if the index case has cleft lip and palate there is no increased risk for isolated cleft palate, and vice versa. Diagnosis the sonographic diagnosis of cleft and palate depends on demonstration of a groove extending from one of the nostrils inside the lip and possibly the alveolar ridge. A transverse scan is required to distinguish isolated cleft lip from cleft lip/palate. Bilateral Cleft Lip and Palate 3D view (yellow arrow "flap") Median cleft lip is usually associated with other facial anomalies (hypertelorism with median cleft face syndrome, hypotelorism with holoprosencephaly). The diagnosis of isolated cleft palate is difficult and in cases at risk for Mendelian syndromes fetoscopy may be necessary. Prognosis Minimal defects, such as linear indentations of the lips or submucosal cleft of the soft palate, may not require surgical correction. Recent advances in surgical technique have produced good cosmetic and functional results. However, prognosis depends primarily on the presence and type of associated anomalies. Etiology Micrognathia is usually associated with genetic syndromes (such as Treacher-Collins, Robin and Robert syndromes), chromosomal abnormalities (mainly trisomy 18 and triploidy) and teratogenic drugs (such as methotrexate). The Robin anomalad (severe micrognathia, glossoptosis and a posterior cleft palate or an arched palate) may be a sporadic isolated finding (in about 40% of cases) or it may be associated with other anomalies or with recognized genetic and non-genetic syndromes. Diagnosis Micrognathia is a subjective finding in the midsagittal view of the face and is characterized by a prominent upper lip and receding chin. Severe micrognathia is associated with polyhydramnios possibly because of the glossoptosis preventing swallowing. Severe micrognathia can be a neonatal emergency due to airway obstruction by the tongue in the small oral cavity. If prenatal diagnosis is made a pediatrician should be present in the delivery room and be prepared to intubate the infant. In general, about half are either lethal or require surgery and half are asymptomatic. Prevalence Cardiovascular abnormalities are found in 5-10 per 1,000 live births and in about 30 per 1,000 stillbirths.

Other Definitions [0065] the following definitions are more general terms used throughout the present application. A salt is composed of one or more cations (positively charged ions) and one or more anions (negative ions) so that the salt is electrically neutral (without a net charge). Salts of the compounds as described herein include those derived from inorganic and organic acids and bases.

In certain embodiments, the molecular weight of a small molecule is at most about 1,000 g/mol, at most about 900 g/mol, at most about 800 g/mol, at most about 700 g/mol, at most about 600 g/mol, at most about 500 g/mol, at most about 400 g/mol, at most about 300 g/mol, at most about 200 g/mol, or at most about 100 g/mol. In certain embodiments, the molecular weight of a small molecule is at least about 100 g/mol, at least about 200 g/mol, at least about 300 g/mol, at least about 400 g/mol, at least about 500 g/mol, at least about 600 g/mol, at least about 700 g/mol, at least about 800 g/mol, or at least about 900 g/mol, or at least about 1,000 g/mol. In certain embodiments, the small molecule is a therapeutically active agent such as a drug. The small molecule may also be complexed with one or more metal atoms and/or metal ions. In this instance, the small molecule is also referred to as an "small organometallic molecule. In certain embodiments, the molecular weight of a large molecule is greater than about 2,000 g/mol, greater than about 3,000 g/mol, greater than about 4,000 g/mol, or greater than about 5,000 g/mol. In certain embodiments, the molecular weight of a large molecule is at most about 100,000 g/mol, at most about 30,000 g/mol, at most about 10,000 g/mol, at most about 5,000 g/mol, or at most about 2,000 g/mol. In certain embodiments, the large molecule is a therapeutically active agent such as a drug. The large molecule may also be complexed with one or more metal atoms and/or metal ions. In this instance, the large molecule is also referred to as an "large organometallic compound. The term, as used herein, refers to proteins, polypeptides, and peptides of any size, structure, or function. Inventive proteins preferably contain only natural amino acids, although non-natural amino acids. Also, one or more of the amino acids in a protein may be modified, for example, by the addition of a chemical entity such as a carbohydrate group, a hydroxyl group, a phosphate group, a farnesyl group, an isofarnesyl group, a fatty acid group, a linker for conjugation or functionalization, or other modification. A protein may be naturally occurring, recombinant, synthetic, or any combination of these. Apolipoproteins also serve as enzyme cofactors, receptor ligands, and lipid transfer carriers that regulate the metabolism of lipoproteins and their uptake in tissues. Accordingly, a chimeric gene or chimeric construct may comprise regulatory sequences and coding sequences that are derived from different sources, or regulatory sequences and coding sequences derived from the same source, but arranged in a manner different than that found in nature. A "foreign" gene refers to a gene not normally found in the host organism, but which is introduced into the host organism by gene transfer. Foreign genes can comprise native genes inserted into a non-native organism, or chimeric genes. A "transgene" is a gene that has been introduced into the genome by a transformation procedure. The polynucleotides can be chimeric mixtures or derivatives or modified versions thereof, single-stranded or double-stranded. The oligonucleotide can be modified at the base moiety, sugar moiety, or phosphate backbone, for example, to improve stability of the molecule, its hybridization parameters, etc. A nucleotide sequence typically carries genetic information, including the information used by cellular machinery to make proteins and enzymes. As examples, phosphorothioate oligonucleotides may be synthesized by the method of Stein et a, Nucl. Vectors can be plasmid, viral, or others known in the art, used for replication and expression in mammalian cells. Alternatively, viral vectors can be used which selectively infect the desired tissue, in which case administration may be accomplished by another route. Non-limiting examples of such modifications include methylation, "caps", substitution of one or more of the naturally occurring nucleotides with an analog, and internucleotide modifications such as, for example, those with uncharged linkages. Polynucleotides may contain one or more additional covalently linked moieties, such as, for example, proteins. The polynucleotides may be derivatized by formation of a methyl or ethyl phosphotriester or an alkyl phosphoramidate linkage. Furthermore, the polynucleotides herein may also be modified with a label capable of providing a detectable signal, either directly or indirectly. Exemplary labels include radioisotopes, fluorescent molecules, biotin, and the like. By "recombinantly produced" is meant artificial combination often accomplished by either chemical synthesis means, or by the artificial manipulation of isolated segments of nucleic acids. Alternatively, it may be performed to join together nucleic acid segments of desired functions to generate a single genetic entity comprising a desired combination of functions not found in nature. Restriction enzyme recognition sites are often the target of such artificial manipulations, but other site specific targets. Plasmids are considered replicons, capable of replicating autonomously within a suitable host. The ability to hybridize will depend on both the degree of complementarity and the length of the antisense nucleic acid. One skilled in the art can ascertain a tolerable degree of mismatch by use of standard procedures to determine the melting point of the hybridized complex. Transcriptional gene silencing is the result of histone modifications, creating an environment of heterochromatin around a gene that makes it inaccessible to transcriptional machinery. Examples of particles include polymeric particles, single-emulsion particles, double-emulsion particles, coacervates, liposomes, microparticles, nanoparticles, macroscopic particles, pellets, crystals, aggregates, composites, pulverized, milled or otherwise disrupted matrices, and cross-linked protein or polysaccharide particles, each of which have an average characteristic dimension of about less than about 1 mm and at least 1 nm, where the characteristic dimension, or "critical dimension," of the particle is the smallest cross-sectional dimension of the particle. A target tissue may be an abnormal or unhealthy tissue, which may need to be treated. A target tissue may also be a normal or healthy tissue that is under a higher than normal risk of becoming abnormal or unhealthy, which may need to be prevented. A "non-target tissue" is any biological tissue of a subject (including a group of cells, a body part, or an organ) or a part thereof, including blood and/or lymph vessels, which is not a target tissue. In some embodiments, treatment may be administered after one or more signs or symptoms of the disease have developed or have been observed. In other embodiments, treatment may be administered in the absence of signs or symptoms of the disease. For example, treatment may be administered to a susceptible subject prior to the onset of symptoms. Treatment may also be continued after symptoms have resolved, for example, to delay or prevent recurrence. As will be appreciated by those of ordinary skill in this art, the effective amount of a compound described herein may vary depending on such factors as the desired biological endpoint, the pharmacokinetics of the compound, the condition being treated, the mode of administration, and the age and health of the subject. The term "therapeutically effective amount" can encompass an amount that improves overall therapy, reduces or avoids symptoms, signs, or causes of the condition, and/or enhances the therapeutic efficacy of another therapeutic agent. The term "prophylactically effective amount" can encompass an amount that improves overall prophylaxis or enhances the prophylactic efficacy of another prophylactic agent. In such cases, the genetic disease will be heritable if it occurs in the germline. A proliferative disease may be associated with: 1) the pathological proliferation of normally quiescent cells; 2) the pathological migration of cells from their normal location. Angiogenesis is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors. The first vessels in a developing embryo form through vasculogenesis, after which angiogenesis is responsible for most blood vessel growth during normal or abnormal development. Angiogenesis is a vital process in growth and development, as well as in wound healing and in the formation of granulation tissue. However, angiogenesis is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer. Angiogenesis may be chemically stimulated by angiogenic proteins, such as growth factors. A neoplasm or tumor may be "benign" or "malignant," depending on the following characteristics: degree of cellular differentiation (including morphology and functionality), rate of growth, local invasion, and metastasis. A "benign neoplasm" is generally well differentiated, has characteristically slower growth than a malignant neoplasm, and remains localized to the site of origin. In addition, a benign neoplasm does not have the capacity to infiltrate, invade, or metastasize to distant sites. Exemplary benign neoplasms include, but are not limited to , lipoma, chondroma, adenomas, acrochordon, senile angiomas, seborrheic keratoses, lentigos, and sebaceous hyperplasias. In contrast, a "malignant neoplasm" is generally poorly differentiated (anaplasia) and has characteristically rapid growth accompanied by progressive infiltration, invasion, and destruction of the surrounding tissue.
