The technical skill of intubation should be practised in adults or older children before attempting to perform even an elective intubation in a small child; many paediatric airway disasters respira to ry could have been avoided with better training blood pressure chart for 60 year old cheap hyzaar 50 mg on-line, also with Anaesthetic induction and intubation in babies requires special assistance on induction. The anaesthetist should always ask care because the oxygen saturation will decrease much faster the surgeon or a nursing colleague to help with induction and than in an adult due to the higher oxygen consumption, high intubation as respira to ry disasters can happen very quickly in minute ventilation and reduced functional residual capacity children. The narrowest part of the airway in the child is the cricoid renal cartilage, not the vocal cords as in the adult. Routine electrolytes and mouth to push the to ngue up, which means the airway is easily creatinine are not necessary except for in renal surgery where it obstructed during facemask anaesthesia. The pressure should be gentle otherwise the trachea can collapse smaller sizes of urinary catheter are often not available, and and you may not be able to ventilate due to obstruction of it is much better to avoid damage to the urethra rather than the trachea itself. Lateral displacement is also a frequent fac to r to insert an inappropriately large catheter. The bladder can be when an assistant is applying cricoid pressure with to o much emptied by the surgeon pressing gently on the lower abdomen enthusiasm. If this is the case, ask your assistant to release the during the case (if the area is surgically prepped), and urine pressure to improve your view of the larynx. Urine output can be estimated from the of these ana to mical diferences and the limited oxygen reserve, diference in weight of the diaper pre-surgery and post-surgery; relatively high oxygen requirement, and poor to lerance of one mg increase in weight in the diaper is equivalent to one ml hypoxia means that intubation can be more difcult in a of urine. A scale capable of measuring small weights must be neonate compared to an adult, but with skill and experience, used. All doses of drugs should be calculated and drawn up safe intubation becomes routine. An open window particularly if the child has been starved for a long period of producing a breeze for the surgical team may cool the time; many children are starved for far to o long preoperatively. If air conditioning is available, Patients in an arid climate often have a chronically low make sure the temperature is not turned down to o low. Most children haema to logy presenting for elective general surgery do not require dextrose -1 Anaemia with haemoglobin level (Hb) less than 8g. Most will blood sugar to increase; neonates or malnourished children be nutritional, but you should consider other causes such as: should have their blood sugar checked to make sure they are not hypoglycaemic before surgery starts. Minor but low technology devices to detect hypothermia are procedures such as hernia repair can be undertaken safely with available, and valuable, particularly in younger children. Children have a relatively elective surgery, and they live relatively close to the hospital, large surface area and little fat for insulation, especially if they should be treated with a course of iron supplements for 3 malnourished. Basic Acute malaria can produce unexpected complications and heating pads and fuid warmers are helpful but need very close increased morbidity. All children presenting for elective surgery moni to ring as they may also cause burns if not used properly. Intraoperative hypothermia can be avoided in the following Children with sickle disease presenting for elective surgery ways: should not be allowed to become dehydrated, and should be transfused using fresh whole blood if the Hb is below 8g. An ambient heating unit is useful to child should have blood taken to test for malaria parasites and warm the room and reduce early heat loss. Essential labora to ry measurements include: A three-year-old male child was referred to a tertiary referral haemoglobin, platelet count, creatinine (allows comparison hospital in East Africa with an 8 month his to ry of enlarging of pre and pos to perative renal function) and blood type and abdominal mass. The child was previously healthy, travelled cross match, anticipating the potential for signifcant blood from a neighbouring country, had been examined by multiple loss. A minimum of two adult units of type specifc blood medical care providers, and was very malnourished. You will need to have a minimum of two blood transfusion sets in theatre, in case one becomes obstructed with blood clots during the case. Pos to perative care must be planned before surgery, including where the child will be cared for after surgery. Typically tumours in sub-Saharan in the area closest to the nursing station with access to close Africa are more advanced and in Nigeria, nephroblas to ma is moni to ring. Anaesthesia and surgery for advanced induction and maintenance of anaesthesia tumour cases can be very challenging. A large intra-abdominal tumour may predispose the patient to regurgitation of gastric contents on induction of anaesthesia. Many of these patients present in a state of Remember, if you are having difculty viewing the glottis, ask malnutrition and their response to inhalation agents such as your assistant to reduce the cricoid pressure and/or change halothane may be more dramatic with more cardiovascular their compression direction to a more midline position. Children can have a more tube can be used if there is no urinary catheter available dramatic drop in oxygen saturation when they are apnoeic compared to adults, due to higher oxygen consumption, and in During the surgical exposure of the tumour, the surgical team this case, the child will also have a reduced functional oxygen could decrease venous return to the heart by compression reserve, so will require efcient intubation. You must watch the surgery closely so that you may assist during the induction period. The lung volumes can anticipate blood loss and be aware of the manipulation will be reduced due to elevation of the diaphragm, so check of the tumour; you should alert the surgeons when the blood more than once that the endotracheal tube is not down to o pressure drops. Tere will be times when you need to have far and is in the proper position in the trachea. If you are will do best with a cufed endotracheal tube, if available, due warming the blood in a bath of warm water, make sure that it to increased intra-abdominal pressure during surgical tumour is not to o hot; if you cannot keep your hand in the water for manipulation. If an uncufed endotracheal tube is all that is more than 5 seconds then it is to o hot and must not be used as available, place the appropriate size tube that only has a leak you can cause haemolysis and massive infusion of potassium. Remember that 98% of the potassium in blood is intracellular; Higher inspira to ry pressures than normal may be required due if the blood becomes haemolysed, the potassium will food out the mass efect of the tumour on the lungs, as would apply of the cells and cause arrhythmias and even cardiac arrest when to any intra-abdominal pathology such as bowel obstruction you transfuse the blood. If the chest is not moving to be given in a 30-60 ml syringe, so that you can keep an well, recheck the position of the endotracheal tube and adjust accurate measurement of blood transfusion volume. Ideally, the inspira to ry pressure; this should be undertaken as a place a three-way s to p cock in the infusion line, which will priority rather than waiting for desaturation or carbon dioxide allow you to keep the syringe attached and to aspirate from the retention to occur. Two large bore intravenous catheters should be inserted in to the upper limbs for surgery. The cannulas are placed in the hands Children having major tumour excision need to have a urinary or arms because the tumour could involve the inferior vena catheter inserted. The surgery will be associated with signifcant pos to perative pain, which should be managed by small doses of morphine or pethidine titrated to efect in the recovery room. Pos to peratively, these patients need to be observed in a setting with a higher nurse to patient ratio, with a bed that can have the head elevated, oxygen in the room, and careful moni to ring of fuid intake and output by the nursing team. If close observation is not possible, intramuscular opioids, at the appropriate dose, may be safer Figure 4. The appropriate (left side of pho to arrowed) can decrease venous return to the heart and dosing based upon accurate weight is critical when dealing the blood pressure will decrease, which should prompt communication with the paediatric surgical patient. The surgeons will usually with the surgical team request a nasogastric tube to be inserted as the child is likely to have a pos to perative ileus after this large intra-abdominal tumour is removed. Pos to perative pain management after settings, so accurate non-invasive blood pressure moni to ring upper abdominal surgery will require careful treatment, with small doses needs to be done every two minutes, ideally using an of opioids titrated to efect, and close moni to ring of respira to ry rate by au to mated cuf. As one can see in the pathological specimen, the ward nurses these tumours will involve a large section of the kidney and one can see haematuria at times. In cases of bilateral tumour case 2 involvement, the surgeons may need to do renal sparing procedures (hemi-nephrec to my), which can be associated A 6-year-old female living in a very rural and resource poor with very large blood loss and high risk for renal dysfunction area of Africa has had a one year his to ry of abdominal swelling pos to peratively. She has travelled for two days to for a surgical consult to have good pain management. It is helpful if, in addition by your outreach team as the area she lives in has minimal page 138 Update in Anaesthesia | A portable ultrasound machine revealed a large intra-abdominal cystic mass and the surgeon would like to proceed to surgery. The hospital is without piped gases or oxygen tanks, no anaesthesia machines, and has one electrically powered oxygen concentra to r that produces fow up to 6 litres. Is this an experienced surgeon who can adjust to the environment and will be able to retreat and s to p surgery if direct visualization of the mass demonstrates a very difcult excisionfi You need to consider these types of questions when working in extremely remote regions Figure 7. The concentration of propofol sets for the family to purchase and bring to the operating (10 mg. Always approximate 1:1 mg:mg combination for infusion, which remember in an emergency situation a full cross match does simplifes the dosing. Most paediatric buretrols have 60 drops of vital signs cannot wait for the full cross match.

At times, you may need a small dose of muscle relaxant induction and maintenance of anaesthesia (succinylcholine) but most surgeons can operate with a A suitable anaesthesia plan in this situation would be to tal spontaneously ventilating patient. Succinylcholine has a short duration of action, which which would be less expensive. This allows for Decrease the infusion rate 15-20 minutes before the projected a greater margin of safety in case the genera to r powered oxygen completion of surgery and s to p completely 5 minutes before concentra to r malfunctions and you are forced to use a self the end. The development of paediatric surgical centres in both the rural and urban settings will allow for greater experience to be obtained in paediatric anaesthesia, which will improve care. The most valuable asset for these paediatric centres is to have well-trained physicians and nurses who can provide high quality care for children with the advanced surgical pathology encountered, taking account of the lack of infrastructure and the limited supplies that are a common problem. A successful perioperative course can be expected even for children requiring surgical intervention in austere environments if the basic foundations of anaesthesia are adhered to and if there is a high level of surgical skill available. Intestinal damage, intraoperative blood loss and pos to perative ileus need to be considered in the 1.

Activities with inherent danger must also be fac to red in to the Although on some level everyone must balance the risks of decision of whether to participate. For example, table tennis engaging in a desired activity against the potential benefits is certainly less dangerous than bullfighting. Finally, other derived from that activity, this cost- to -benefit analysis fac to rs, such as medication compliance, medication side assumes added significance for the person with epilepsy. A effects, age, concomitant medical problems, use of safety person with epilepsy must conduct the analysis in the context equipment, and a prolonged and consistent aura, can all of a specific situation, with the consideration that a seizure influence the risks faced by a person with epilepsy when related injury might occur during the specific activity. Fac to rs that influence seizure recurrence have been reported (3) and may provide important insight in to deter the Risks mining the risks associated with a desired activity. Partial seizures are also more likely to recur lege is governed by individual country, state, or terri to rial compared with an initial major mo to r seizure (4,7). There are approximately 225 million reg etiology of a seizure disorder is head injury, the risk for recur istered vehicles in the United States. These crashes resulted in approximately 3 mil 5 years, respectively (8), with severe head injury defined as lion injuries and more than 42,000 deaths (12).

Seizures caused by alcohol use, on the other hand, who drive with or without a valid license is unknown. In a prospective optimum seizure-free interval for the protection of both the survey of 367 patients with localization-related epilepsy person with epilepsy and the public. The paucity the Regula to ry Requirements of available data makes it difficult to definitively establish the number of au to mobile crashes caused by persons with the first seizure-related car crash was reported near the turn of epilepsy who have a seizure while driving. Since then, regula to ry authorities have placed that persons with epilepsy account for approximately 0. In decade ago, the American Academy of Neurology, the American contrast, alcohol-related crashes comprise approximately Epilepsy Society, and the Epilepsy Foundation of America 7% of car crashes but account for approximately 40% of all convened a conference of thought leaders to issue guidelines fatalities nationwide (17). Seizures are unpredictable, and the presumption is that Recommendations from the conference included (i) a seizure longer seizure-free intervals translate in to a decreased likeli free interval of 3 months, (ii) allowances for purely nocturnal hood of seizure-related crashes. Verifying this is difficult, seizures, and (iii) a provision allowing driving when there is an however, as individual driving records are generally not established pattern of a prolonged and consistent aura (21). A recent retrospective survey of patients Determining the risk of a crash caused by the driver with in several Maryland outpatient epilepsy clinics suggested epilepsy is difficult. Traditionally, the duration of seizure free that the risk of mo to r vehicle crashes was reduced by 85% dom is used by authorities to determine when it is safe for a per and 93% if the patient did not have a seizure at 6 months son with epilepsy to drive. This survey relied on self jurisdictions vary widely and have many unique exceptions (22). State regula to ry agencies and the Epilepsy Foundation of It has been suggested that self-reporting of crashes by America website ( Drazkowski and laws governing driving and epilepsy, which has been recently colleagues (16) reviewed actual accident reports in Arizona updated (23). In an edi to rial, Krumholz suggested that it is time from crashes caused by seizures before and after the seizure to consider uniform laws governing epilepsy and dri free interval was reduced from 12 to 3 months (Table 94. International rules on Although no significant increases in seizure-related crashes driving have been reviewed, and because of the high variability were reported, the retrospective study provided some objec among individual countries, it has been suggested that the appro tive data on these crashes. To date, no controlled prospective priate national authority be consulted to determine current local data are available to guide regulating authorities as to the laws regarding driving before traveling to these nations (25). Seizure-related mo to r vehicle crashes in Arizona before and after reducing the driving restric tion from 12 to 3 months. Chapter 94: Driving and Social Issues in Epilepsy 1053 Six states currently have laws that require health care persons with epilepsy, poorly controlled epilepsy is associated providers to report persons with epilepsy to the appropriate with a high level of unemployment (34). The rationale behind the reporting also impacts employment status, with an earlier age of onset requirement is that a person with epilepsy will not reliably correlating with work difficulties later in life (35). In patients self-report the presence of active or recurrent seizures to the with adult-onset epilepsy, initial seizure control or lack of con proper authority. A survey of young persons with their seizures to avoid being reported and potentially losing epilepsy enrolled in a job-training program in Ireland indi their license (19). Of persons with epilepsy who had been cated that 50% of the participants believed they were being counseled about driving laws, only 27% reported their condi actively discriminated against when seeking employment (37). The law was intended to help persons with epilepsy and authorities, less than 10% were counseled in a major metro persons with other disabilities obtain and retain employment. Furthermore, what constitutes a reason showing that physician reporting reduces seizure-related au to able accommodation was left open to interpretation. In Canada, a conference of invited experts dard may be based on the actual cost of any modifications concluded that the laws requiring health care professionals to required that allow a person to keep a specific job. This edi to rial ers like it have changed the thinking on what defines disability highlighted several other medical conditions and situations for many patients. These uncertainties and restrictive rulings by that are associated with a similar or higher relative risk of a car the court have prompted a reevaluation of the issue by the crash compared with epilepsy, such as sleep, apnea, diabetes, United States Legislature which resulted in the passage of the dementia, and cell phone use (distraction) (29). The law was passed in an effort to clarify and be more inclusive on what constitutes disability under the law. A potentially helpful website, the Job accommodation rate is approximately 64% (33). When making with epilepsy must carefully evaluate jobs involving dangerous decisions about participating in any activity, a person with machinery, or equipment heights, or situations in which there is epilepsy must consider the consequences of a seizure that may a possibility for injury or death because of potentially danger occur at any moment during that particular activity. The unpredictability ate a truck in interstate commerce must overcome significant of uncontrolled seizures might pose a serious threat should a hurdles imposed by the Federal Department of Transportation. Operating mo to rized vehicles the diagnosis of epilepsy and the use of antiepileptic drugs is associated with a prolonged danger period. Persons with epilepsy are required to provide small aircraft may not require a license, but these are unlikely to specific evidence, through medical records documenting that be any safer than a private plane should a mishap occur. Other fac Other mo to rized vehicles, such as mo to rcycles, personal to rs, such as postictal effects of seizures and side effects of pre watercraft, all terrain vehicle (four wheel), and boats may pose scribed medications, may be considered in determining disabil less of a threat to a person with epilepsy than does flying. If the ity, especially during a hearing or an appeals process for a person with epilepsy operating the vehicle has a prolonged and denied claim. The specific listings for epilepsy are sections consistent aura, it may allow that person the opportunity to 11. This listing is in the psychiatry section of the a common accident among persons with epilepsy (42). Although a person operating such a vehicle does Low risk not require a license, specific training courses are available and Track are highly recommended. Cross-country skiing In contrast, organized mo to r sports generally require some Golf form of medical clearance before participation (39). Weight training (machines) Each series requires approval from a qualified health care pro Moderate risk fessional before driving, and therefore specific rules should be Football reviewed. Biking Soccer Gymnastics the Person with Epilepsy and Athletics Horseback riding Basketball the decision to participate in individual. The extent to which a person with Hang gliding epilepsy wishes to pursue athletics is an individual decision Mo to r sports that should be based on individual circumstances. Each team Boxing or individual sport presents different challenges that may affect a person with epilepsy in different ways. Many one-on Downhill skiing/ski flying one sports are less likely to pose a threat to a person with Long-distance swimming epilepsy. For diving is also not regulated from a medical standpoint, but example, zonisamide reduces sweating in children and could good judgment is required on the part of the participant. Tremor Hyperventilation techniques and the high concentration of associated with the use of valproic acid could be dangerous inspired oxygen used during scuba diving have the potential to when shooting target pis to ls. The person with epilepsy should also inform potentially be deadly while riding a mo to rbike (47). Many his or her dive buddy, instruc to r, and dive master of the poten more potential examples could be conceived and listing all the tial risk should a seizure occur during diving. Water sports and potential combinations is beyond the scope of this chapter, drowning pose a likely threat to the person with epilepsy. A study by Gotze found no increase in seizure tion in recreational and sporting activities. The patient with epilepsy poses many challenges to the health Recent opinion has encouraged sports participation for the care professional. In addition to the usual concerns persons person with epilepsy despite the potential risks (45,46).

Pyridoxine-dependent seizures (124 blood pressure medication diltiazem order cheap hyzaar,125) usually arise Hypoglycemia may itself cause brain damage independent between birth and 3 months of age hypertension kidney disease buy hyzaar mastercard, although atypical cases of the seizures heart attack vital signs cheap hyzaar line.

Affected newborns appear multifocal sharp waves, and focal electrographic seizures normal at birth. Neonatal seizures, initially rare, increase in evolving to hypsarrhythmia later in the first year. The discussion been found in multiple individuals with pyridoxine-dependent below is limited to the diagnosis of common neonatal condi seizures (127).

Neurocutaneous Syndromes Among the neurocutaneous syndromes that may give rise to Chronic Causes neonatal seizures is familial incontinentia pigmenti, a mixed syndrome of different mosaicisms (139). Perinatal inflamma Some neonatal seizures result from long-standing disorders, to ry vesicles are followed by verrucous patches that produce a such as cerebral dysgenesis, neurocutaneous syndromes, distinctive pattern of hyperpigmentation and finally dermal genetic disorders, or very early onset epilepsy. Better known as hypomelanosis of I to , its cutaneous lesions appear as areas of hypopigmentation. Linear sebaceous nevi are a family of disorders with dis tinctive raised, waxy, sometimes verrucous nevi on the scalp or face, associated with hemihypertrophy, hemimegalen cephaly, and neonatal seizures (142).

A recent case report treatment recommendations rest almost entirely on conven identified a disruption of the tyrosine protein kinase recep to r tional wisdom and traditional practices. On the one hand, if the burden of loading doses of phenobarbital 15 to 20 mg/kg, with the in seizures will be minimal, the infant need not be exposed to tention of generating serum levels between 15 and 20 g/mL, acute and long-term drug therapy. Plasma ized, controlled study (158), thiopental was administered soon binding of phenobarbital in neonates varies from 0% to 45%. For pheno after perinatal asphyxia resulted in a lower rate of recurrent barbital, the volume of distribution is assumed to be 1 L/kg. Another randomized study using achieve, but not exceed, free concentrations of 3 g/mL phenobarbital prophylactically in neonates with perinatal (162,165). The dosing formula: (3 g/kg) Vd (L/kg)/ asphyxia found a statistically significant decrease in the inci (% free binding) assumes a volume of distribution of 1 L/kg.

Few drugs nate the clinical manifestation of the seizure while the electro for use in the newborn have been subjected to adequately pow graphic discharge continues (161,162). This disconnect is ered, randomized, placebo-controlled investigations to demon often termed uncoupling and poses serious concerns for the strate real safety and efficacy. Drugs with potential for the treat clinician and researchers in determining response rates to ment of neonatal seizures are no exception. However, in this critical time of early brain development, suppression of synaptic transmission may have incidental undesirable consequences, because neu ronal and synaptic pruning are activity dependent. Acute neonatal seizures are often followed by 1970s, it has been known that rat pups fed phenobarbital chronic postnatal epilepsy. A latent period, during which secondary have later reductions in brain weight and in to tal brain cell epilep to genesis develops, gives rise to spontaneous, unprovoked count (186). Likewise, benzodiazepines are Chronic Postnatal Epilepsy and the Need commonly administered for sedation or to reduce agitation, for Long-Term Treatment and no obvious adverse effects are associated with their use, although careful studies are lacking. Chronic postnatal epilepsy is relatively common in the wake of neonatal seizures (Fig. For many patients, perma nent, fixed brain injuries, such as resolving stroke, ischemia, References or traumatic lesions, serve as the nidus for future epilepsy.

Temporal lobe seizures are respect to epilepsy was uniformly more favorable, and they more likely to begin early but remit permanently if a first were more likely to be neurologically normal. A single are now recognized as a relatively benign, age-dependent gene is held responsible, because the siblings of patients with epilepsy syndrome and the most prevalent form of seizure in temporal lobe and febrile seizures have a similar incidence of early life. Sibling risk approaches 30% if one par age, associated with fever but without evidence of intracranial ent has had a febrile seizure. This definition is useful febrile seizures in Asian compared with European or North because it emphasizes age specificity and the absence of under American families suggests a strong, genetically determined lying brain abnormalities. All affected individuals present with recurrent febrile child with a brief nonfocal febrile seizure, an infant or child in seizures by 3 years of age, with no evidence of structural brain febrile status epilepticus requires immediate medical attention. Epidemiologic studies have been especially useful epilepsy compared with that reported in general population in identifying features of the seizure or the patient that involve studies or in families with febrile seizures (17). Understanding these fac to rs forms the in large kindreds have recently identified two novel loci on basis of proper seizure management and family counseling.

Nuestro hospital es uno de los cuatro de Madrid que tienen especialistas en Cirugia Maxilofacial de guardia y el unico en la zona sur. Es to implica que es hospital de referencia para esta tipo de pa to logia de to dos los Hospitales del sur-oeste de la Comunidad. En la Urgencia Pediatrica del Hospital 12 de Octubre se atienden anualmente una media de 300 pacientes con esta pa to logia; ademas de los ninos de nuestra propia Area que vienen por cuenta propia o enviados por los pediatras de Atencion Primaria, tambien acuden pacientes de otras areas derivados desde su hospital de referencia. Si en el Hospital se dispusiera de un pro to colo validado por ambas especialidades y coordinado por la Unidad de Calidad la mayoria de los traumatismos se podrian manejar en la Urgencia Pediatrica de forma homogenea, mas rapida y lo que es mas importante segura para el nino independientemente de la experiencia personal del facultativo. De forma similar, si dispusieran de un documen to que avalara su actuacion, podrian actuar los pediatras de Atencion Primaria de nuestra Area y los pediatras de guardia de los Hospitales perifericos que nos derivan pacientes. La derivacion a nuestro Hospital y nuestra llamada al especialista de Cirugia Maxilofacial seria exclusivamente cuando estuviese indicado por la propia pa to logia. Las fracturas nasales son las mas frecuentes de la region facial, debido a su facil exposicion a los traumatismos y a su minima resistencia a fracturarse. La incidencia de fracturas nasales varia segun au to res entre el 10 y el 20%, siendo su etiologia principal en la edad pediatrica los traumatismos accidentales por caidas. Requieren un tratamien to quirurgico para la reduccion cerrada de los fragmen to s oseos desplazados, excep to en casos muy complejos con grandes deformidades nasales o con amplias heridas cutaneo-mucosas que permitan acceder directamente a su reduccion abierta. Esquele to oseo Los huesos propios nasales se insertan en una base esqueletica, se prolongan hacia arriba y hacia delante con el hueso frontal y hacia abajo y afuera con la apofisis ascendente del maxilar superior. Su porcion central esta constituida por la lamina osea vertical, formada por la lamina perpendicular del etmoides y el vomer, que descansa sobre la cresta maxilar. Esquele to cartilaginoso Esta compues to por el cartilago cuadrangular que en su borde inferior forma la region columelar y posteriormente se articula con la lamina perpendicular del etmoides y el vomer. De forma variable en numero y localizacion, se encuentran los cartilagos sesamoideos, normalmente situados entre los cartilagos alares y laterales, y en la columela. No olvidar detallar en la his to ria si existen antecedentes de interes en cuan to a tratamien to s o enfermedades relevantes como alteraciones de la coagulacion. Valoraremos la deformidad, presencia de escalones oseos o crepitacion existente que nos daran una idea aproximada del tipo de fractura ante el que nos encontramos. Se utilizan las siguientes proyecciones: Radiografia lateral de huesos propios, la proyeccion de Waters (para observar los senos paranasales). El valor de la radiografia es limitado y la decision terapeutica suele basarse en los hallazgos clinicos. En general se recomienda no realizarla en ninos menores de 4 anos, dado que por debajo de esta edad el tabique nasal es muy pequeno y se superpone con las estructuras oseas colindantes, lo que dificulta mucho valorar una posible fractura. En cuan to al momen to de la reduccion depende del grado de tumefaccion nasal y la hora de la ultima ingesta Las lesiones valoradas poco tiempo despues del traumatismo (1-3 horas) en general pueden ser reducidas inmediatamente, pero siempre y cuando el paciente este en ayunas 7 (incluidos liquidos) de mas de seis horas. Si la nariz esta ya muy hinchada, la reduccion se debe posponer hasta la palpacion correcta de la deformidad. Las condiciones idoneas de reduccion se producen con el paciente bajo anestesia general, siempre que las condiciones clinicas del paciente lo permitan. Se utilizan como vias de abordajes las tecnicas estandar de rinoplastia abierta, las heridas existentes o las vias de abordajes necesarias para tratar las fracturas asociadas: bicoronal, transconjuntival, subciliar etc. Su tratamien to conlleva el drenaje urgente, antibioterapia y taponamien to endonasal para evitar la recidiva.

Age greater than 60 and a diagnosis of cancer independently predispose patients to an increased risk of coagulopathy. Resistance is defined as progressive disease while on treatment, with or without an initial response, or relapse within 6 months of completing treatment with an anthracycline containing adjuvant regimen. Subsequent dose adjustment is recommended as outlined in Table 2 and Table 3 (depending on the regimen) if a patient develops a grade 2 to 4 adverse event [see Warnings and Precautions (5. Each light peach-colored tablet contains 150 mg of capecitabine and each peach-colored tablet contains 500 mg of capecitabine. Most adverse reactions are reversible and do not need to result in discontinuation, although doses may need to be withheld or reduced [see Dosage and Administration (2. Patients with severe diarrhea should be carefully moni to red and given fluid and electrolyte replacement if they become dehydrated. These adverse reactions may be more common in patients with a prior his to ry of coronary artery disease. Patients with anorexia, asthenia, nausea, vomiting or diarrhea may rapidly become dehydrated. Dose modifications should be applied for the precipitating adverse event as necessary [see Dosage and Administration (2. Patients with moderate renal impairment at baseline require dose reduction [see Dosage and Administration (2. Patients with mild and moderate renal impairment at baseline should be carefully moni to red for adverse reactions. Prompt interruption of therapy with subsequent dose adjustments is recommended if a patient develops a grade 2 to 4 adverse event as outlined in Table 2 [see Dosage and Administration (2. Capecitabine caused embryolethality and tera to genicity in mice and embryolethality in monkeys when administered during organogenesis. Grade 1 is characterized by any of the following: numbness, dysesthesia/paresthesia, tingling, painless swelling or erythema of the hands and/or feet and/or discomfort which does not disrupt normal activities. Grade 3 hand-and-foot syndrome is defined as moist desquamation, ulceration, blistering or severe pain of the hands and/or feet and/or severe discomfort that causes the patient to be unable to work or perform activities of daily living. Of 566 patients who had hepatic metastases at baseline and 309 patients without hepatic metastases at baseline, grade 3 or 4 hyperbilirubinemia occurred in 22. Of the 136 colorectal cancer patients with grade 3 or 4 hyperbilirubinemia, 49 patients had grade 3 or 4 hyperbilirubinemia as their last measured value, of which 46 had liver metastases at baseline. A to tal of 18 deaths due to all causes occurred either on study or within 28 days of receiving study drug: 8 (0. A to tal of 82 deaths due to all causes occurred either on study or within 28 days of receiving study drug: 50 (8. In the monotherapy arm docetaxel was 2 administered as a 1-hour intravenous infusion at a dose of 100 mg/m on the first day of each 3 week cycle for at least 6 weeks. The mean duration of treatment was 129 days in the combination arm and 98 days in the monotherapy arm. A to tal of 66 patients (26%) in the combination arm and 49 (19%) in the monotherapy arm withdrew from the study because of adverse reactions. The percentage of patients requiring dose reductions due to adverse reactions was 65% in the combination arm and 36% in the monotherapy arm. The percentage of patients requiring treatment interruptions due to adverse reactions in the combination arm was 79%. Treatment interruptions were part of the dose modification scheme for the combination therapy arm but not for the docetaxel monotherapy-treated patients. A to tal of 13 out of 162 patients (8%) discontinued treatment because of adverse reactions/intercurrent illness. Monotherapy (Metastatic Colorectal Cancer, Adjuvant Colorectal Cancer, Metastatic Breast Cancer) Gastrointestinal: abdominal distension, dysphagia, proctalgia, ascites (0. This interaction is probably due to an inhibition of cy to chrome P450 2C9 by capecitabine and/or its metabolites. Leucovorin the concentration of 5-fluorouracil is increased and its to xicity may be enhanced by leucovorin. Deaths from severe enterocolitis, diarrhea, and dehydration have been reported in elderly patients receiving weekly leucovorin and fluorouracil. Capecitabine at doses of 198 mg/kg/day during organogenesis caused malformations and embryo death in mice. Malformations in mice included cleft palate, anophthalmia, microphthalmia, oligodactyly, polydactyly, syndactyly, kinky tail and dilation of cerebral ventricles. At doses of 90 mg/kg/day, capecitabine given to pregnant monkeys during organogenesis caused fetal death. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from capecitabine, a decision should be made whether to discontinue nursing or to discontinue the drug, taking in to account the importance of the drug to the mother. No clinical benefit was demonstrated in two single arm trials in pediatric patients with newly diagnosed brainstem gliomas and high grade gliomas. In both trials, pediatric patients received an investigational pediatric formulation of capecitabine concomitantly with and following completion of radiation therapy ( to tal dose of 5580 cGy in 180 cGy fractions). The first trial was conducted in 22 pediatric patients (median age 8 years, range 5-17 years) with newly diagnosed non-disseminated intrinsic diffuse brainstem gliomas and high grade gliomas. In the dose-finding portion of the trial, patients received capecitabine with concomitant radiation 2 2 therapy at doses ranging from 500 mg/m to 850 mg/m every 12 hours for up to 9 weeks. After 2 a 2 week break, patients received 1250 mg/m capecitabine every 12 hours on Days 1-14 of a 21 day cycle for up to 3 cycles. All patients received 650 mg/m capecitabine every 12 hours with concomitant radiation therapy for up to 9 weeks. After a 2 week break, patients received 2 1250 mg/m capecitabine every 12 hours on Days 1-14 of a 21-day cycle for up to 3 cycles. There was no improvement in one-year progression-free survival rate and one-year overall survival rate in pediatric patients with newly diagnosed intrinsic brainstem gliomas who received capecitabine relative to a similar population of pediatric patients who participated in other clinical trials. Medical management of overdose should include cus to mary supportive medical interventions aimed at correcting the presenting clinical manifestations. Each light peach-colored tablet contains 150 mg capecitabine and each peach-colored tablet contains 500 mg capecitabine. Distribution Plasma protein binding of capecitabine and its metabolites is less than 60% and is not concentration-dependent. Some human carcinomas express this enzyme in higher concentrations than surrounding normal tissues. Excretion Capecitabine and its metabolites are predominantly excreted in urine; 95. Systemic exposure to capecitabine was about 25% greater in both moderately and severely renal impaired patients [see Dosage and Administration (2. Capecitabine was clas to genic in vitro to human peripheral blood lymphocytes but not clas to genic in vivo to mouse bone marrow (micronucleus test). Fluorouracil also causes chromosomal abnormalities in the mouse micronucleus test in vivo. Impairment of Fertility In studies of fertility and general reproductive performance in female mice, oral capecitabine 2 doses of 760 mg/kg/day (about 2300 mg/m /day) disturbed estrus and consequently caused a decrease in fertility. In males, this dose caused degenerative changes in the testes, including decreases in the number of sperma to cytes and spermatids. The starting dose was reduced in patients with moderate renal impairment (calculated creatinine clearance 30 to 50 mL/min) at baseline [see Dosage and Administration (2. Subsequently, for all patients, doses were adjusted when needed according to to xicity. The two clinical studies were identical in design and were conducted in 120 centers in different countries. The 2 approved dose of 100 mg/m of docetaxel administered in 3-week cycles was the control arm of the phase 3 study. A to tal of 511 patients with metastatic breast cancer resistant to , or recurring during or after an anthracycline containing therapy, or relapsing during or recurring within 2 years of completing an anthracycline-containing adjuvant therapy were enrolled. In the monotherapy arm, 256 patients received docetaxel 100 mg/m as a 1 hour intravenous infusion administered in 3-week cycles. The primary endpoint was tumor response rate in patients with measurable disease, with response defined as a fi50% decrease in sum of the products of the perpendicular diameters of bidimensionally measurable disease for at least 1 month. The baseline demographics and clinical characteristics for all patients (n=162) and those with measurable disease (n=135) are shown in Table 18. Resistance was defined as progressive disease while on treatment, with or without an initial response, or relapse within 6 months of completing treatment with an anthracycline-containing adjuvant chemotherapy regimen.
