The second case is a ten year old male who had received numerous medications over the past several years medicine neurontin order reminyl with a visa. Despite these treatments medications 8 rights buy reminyl 8mg fast delivery, and optimal family environment and commitment medications with pseudoephedrine reminyl 8mg overnight delivery, the primary symptoms of mood instability and cognitive impairment continued medications before surgery purchase reminyl 4mg amex. The quetiapine was discontinued due to associated insomnia and worsened mood and behavioral states symptoms checker 8mg reminyl with visa. At the time of the review the child presented with neurological immaturity treatment plan for depression discount reminyl online visa, delayed fine motor integration, jerky saccadic eye movements and possible symptoms of partial complex seizures. Subsequent to improved emotional stability and broadly reduced symptoms the contribution of aripiprazole was assessed by a dose reduction to 2. Plans were made to subsequently assess his stimulant treatment response as the monitoring continued.

While a single drug has not triumphed in the treatment of autism spectrum disorders, many drugs have proven helpful to varying degrees and for various purposes. Pharmacological Neuromodulation in Autism Spectrum Disorders 307 It is proposed that pharmacological approaches with neuroprotective characteristics have potential to reduce the dynamic pathogenic states that are likely occurring in highly symptomatic young children who are in developmentally critical stages of neural patterning and maturation. In a manner similar to the example provided regarding atypical antipsychotics, drugs will increasingly be chosen based on their particular characteristics or used together for separate or synergistic effects. Arriving at a full understanding of these approaches will take further studies that consider the potential for unwanted effects. The most frequently reported adverse effects were sleep disorders, excitement, hyperkinesia, enuresis and diarrhea. It will be important to learn if sapropterin’s benefits are primarily from developmentally critical neuroprotective effects and/or effects on neurotransmitters. It will also be important to determine if indiscriminate neurotransmitter potentiation in dysregulated neurons and circuits are being reflected in the adverse effect profile that some demonstrate. Synaptic molecules are important targets for protective treatments, to slow disease progression and preserve cognitive and functional abilities by preserving synaptic structure and function. Glutamate receptors and post synaptic density proteins play a central role in excitatory synaptic plasticity. Synaptic dysregulation may contribute to brain disorders present in those with Autism Spectrum Disorders by preventing appropriate synaptic signaling and plasticity. The synapse constitutes an important target for treatments to slow progression and preserve cognitive and functional abilities in these diseases. These hypotheses are consistent with those that identify the final common pathway of many neuropsychiatric diseases as synaptic pathology. Such treatments may one day provide preventative pharmacological interventions as well as those that can reduce impairment and improve functioning. Memantine, as an augmenting agent, demonstrated significant improvements in open-label use for language function, social behavior, and self-stimulatory behaviors, although selfstimulatory behaviors comparatively improved to a lesser degree. The efficacy and safety of dextromethorphan and quinidine was demonstrated in clinical trials of late stage neurological conditions (amyotrophic lateral Sclerosis and Multiple Sclerosis) demonstrating reductions of emotional lability and improvements in sleep. This is an important therapeutic for those suffering the debilitating effects of pseudobulbar affect. The efficacy in reducing dysregulated and involuntary congruent and incongruent emotional expressions is a significant achievement. Future studies will help us determine if these unique characteristics will lead to improved outcomes for those with autism spectrum disorders. Conclusion the distress, irritability and emotional lability often seen in Autism Spectrum Disorders may be a reflection of pathological glutamatergic functioning or otherwise dysregulated circuits relative to inhibitory-excitatory balance. When sustained, these symptoms demonstrate potential for pathological development of abnormal neural circuits capable of dysregulation through neural synchronicity and state dependent effects on genetic expression. Within the framework of this hypothesis the neural plasticity and critical periods, present in developing brains, place them at particular risk. Early pharmacological intervention related to severe emotional lability, irritability and dysregulated circuits may also reduce the pathogenic potential and reduce or prevent the development or maintenance of pathological processes.

Introduction Menopause represents the final stage of the continuous process of reproductive aging in a woman’s life, marking the end of her fertility. Preceded by endocrine and menstrual cycle changes described as menopausal transition, natural menopause occurs at an average age of approximately 51 years, although a high inter-individual variability is supported by results from epidemiological studies. However, occurrence of menopause outside the estimated normal age interval (45-55 years) is associated with increased morbidity, either when a late or on the contrary, a premature cessation of menstruation appears. A late menopause implies a longer exposure to estrogens and a possible increased risk for breast (Colditz, 1993; Kelsey & Bernstein, 1996) and endometrial cancer (Dossus et al. On the other hand, women entering menopause earlier are facing a hypo-estrogenic state for a longer period compared to women undergoing normal menopause. Women facing a premature cessation of the ovarian function were shown to be at increased risk for premature death, cardiovascular disease, neurologic disease, mood disorders, osteoporosis or psychosexual dysfunction (Shuster et al. As the main rationale for these disorders was linked to hormonal changes, maintaining a certain level of ovarian steroids for a given period of time arose as an essential condition for conserving life quality in women (Wilson, [1966]). Accentuated by the increasing life span, researches related to menopause and its treatment have provided scientific community with an increased body of data during the last decades. This characteristic is maintained until menopause, when subsequent to a decline in ovarian synthesis, sex steroid plasmatic levels rely only to the less significant amounts produced peripherally. In the particular case of pregnant women, the pivotal role for steroid secretion shifts from ovaries to placenta. Ovarian secretion of sex steroids during reproductive age follows a monthly cyclic evolution under the control of pituitary gonadotropins (Figure 1A). The pharmacological basis of hormone replacement therapy is to compensate the decrease of estradiol production by ovaries in order to limit the adverse events due to sex steroids deficiency. In the second class of female sex steroids, progesterone represents the most important component, with significantly higher secreted levels than 17-hydroxyprogesterone, the other naturally occurring progestogen (Figure 2). Due to their lipophilic nature, steroids will easily cross the cell membrane and bind to specific receptors, resulting in hormone-receptor complexes. Prior to ligand binding, receptors are inactive and associate protein complexes, among which the heat shock proteins (hsp) play important roles. The expression of target genes is thus modulated after interaction with various coregulators (Rosenfeld & Glass, 2001; Amazit et al. Furthermore, the complexity of oestrogen and progesterone actions is enhanced by the growing body of evidence supporting the non-genomic mechanisms of steroid hormones action (Hammes & Levin, 2007; Levin, 2011; Losel & Wehling, 2003). These rapid effects may not be explained by the classic pathway and involve a variety of signalling events, such as the activation of various kinases, ion channels regulation and intracellular calcium mobilization or nitric oxide synthesis (Edwards, 2005; Madak-Erdogan et al. Secondary sex characteristics are under the Pharmacology of Hormone Replacement Therapy in Menopause 317 close control of gonadal steroids. During the reproductive lifetime of a woman, oestrogens dictate the proliferation of the uterine endometrium and the development of endometrial glands, while progesterone promotes secretory changes of the endometrium, in a process of preparation of the ideal milieu for implantation of the fertilized ovum. In the breast, oestrogens promote the development of the stromal and ductal systems together with fat deposition at this level, and progesterone induces the development of the secretory units of the breast, causing alveolar cells to proliferate. Although the reproductive system represents the principal target for sex steroids, their effects are far from being limited only to this system. Bone health, for instance, is greatly influenced by oestrogens levels, as they play an important role in the process of bone remodelling. Under their action, skeletal resorption is diminished due to a decreased osteoclastic activity and by consequence, bone formation is promoted. Furthermore, a cardioprotective role exerted by ovarian steroids was inferred due to the significantly lower rates of cardiovascular diseases manifested by women prior to menopause compared to men and the cancelation of these gender differences following menopause. Menopause principal consequences Given the multitude of physiological effects exerted by sex steroids in women, it is not surprising that the hormonal changes related to menopause have been linked to a wide spectrum of symptoms and disorders. Furthermore, the increased risk of dementia and Alzheimer disease in postmenopausal women was also partially attributed to endogenous oestradiol depletion (Yaffe et al. All-cause mortality rates in women appear to be associated with age at menopause, women entering menopause before 40 years having mortality rates twice as the ones seen in the 50-54 years group (Snowdon et al. Finally, an increased risk for cognitive impairment, dementia and Parkinson disease, inversely proportional with age at menopause, was reported in premature menopausal women following oophorectomy (Rocca et al. That was the hypothesis guiding clinicians decisions about substitution of ovarian steroids in menopause. It should not be used as a mean of chronic disease prevention and it is advisable to restrict treatment administration to the shortest period and the lowest dosage possible to control symptoms effectively. In most women, excepting hysterectomized patients, menopausal treatment requires preparations combining oestrogens with a progestin, the latter being used mainly to balance oestrogen’s effects on the endometrium and to avoid endometrial hyperplasia and an increased risk of secondary carcinoma. This combination therapy may be administrated either in a sequential cyclic regimen or in a continuous one. The sequential regimen involves the alternation of a pure oestrogenic period to an oestro-progestative one, leading to withdrawal bleeding when the progestin administration is discontinued. This regimen is commonly administrated with a monthly cyclicity including at least 10 days of progestin treatment. Quarterly regimens are also available, involving progestin administration every 3 months, although in this case the risk for endometrial hyperplasia needs further evaluation. The continuous combined treatment implies the administration of both compounds on a daily basis and uses lower doses of progestin compared to the sequential regimen. This constitutes an option especially in older women not desiring a monthly withdrawal bleeding, even if uterine bleeding with unpredictable onset may not be excluded particularly during the first administrations (Doren, 2000; Ylikorkala & Rozenberg, 2000). Thus, after exclusion of other possible causes, androgen therapy represents an option for menopausal women with hypoactive sexual desire disorder undergoing concomitant oestrogen treatment, especially in those who have suffered a surgical menopause (Davis et al. These are pharmacologic agents characterised by variable oestrogen activity, acting as oestrogen agonists in some tissues while in other tissues they exert oestrogen antagonist effects. There is an urgent need to develop evidence-based guidelines relying on solid research in order to optimize the care of this group of women (Panay & Kalu, 2009). In an attempt to explain the disparity between these results the timing hypothesis arose as a possible answer, supported by differences between women enrolled in this study and those participating in observational studies (Grodstein et al. Animal studies supported this hypothesis and demonstrated that the positive cardiovascular effects of hormonal substitution are inversely correlated with the delay of initiating the treatment (Clarkson, 2007). Additionally, this positive effect appears to be present even when lower doses of oestrogen are used (Lindsay et al. The relation between colorectal cancer and hormone exposure is further complicated by recent evidences suggesting that a greater endogenous estrogen exposure may increase the risk of colorectal cancer in postmenopausal women (Clendenen et al. However, as either current evidences are insufficient or their impact on the overall benefitrisk balance is not significant, we will not detail them. Secondly, the breast cancer risk profile differs in women undergoing a premature menopause compared to the general population. A younger age at menopause is protective against breast cancer regardless of whether the menopause was natural or surgical (Hulka & Moorman, 2008). Pharmacology of hormone replacement therapy the pharmacology of hormone replacement therapy is of a particular interest given the complex benefit/risk balance and the importance of this treatment for women health. Our analysis will be limited to the pharmacology of the natural sex steroid 17β-estradiol. In turn, following oral administration, oestradiol is subject to the firstpass effect, a term that encompasses the metabolic changes underwent by a drug before it reaches systemic circulation. This results in the use of higher doses of oestradiol (~ 1,5 mg/day) compared to parenteral routes (patch ~ 50µg/24h). Moreover, subsequent to the various metabolic changes suffered by oestrogens once absorbed in the intestinal tract, a specific profile of oestradiol metabolites and oestrogen-dependent serum parameters with particular pathophysiological implications will appear, widely different from what is observed after the use of transdermal oestradiol where the first-pass effect is avoided. Subsequent to this process, the oestrone/ oestradiol ratio resulting from oral administration is significantly higher (approximately 5:1) than the one observed following transdermal administration (approximately 1:1, which is similar to the physiologic ratio found in premenopausal women)(Kuhl, 2005). The first pass effect of oestradiol results in various biological consequences (De Lignieres et al. Oxidative metabolites, such as hydroxyestradiol and quinone derivatives, are conjugated by various phase-2 enzymes. The oral route of oestradiol administration is easy and convenient, however the hormone is extensively metabolized in the gut and the liver leading to first-pass effect and, as previously mentioned, to a high estrone/oestradiol ratio (Kuhl, 2005). On the other hand, transdermal 17β-oestradiol is well absorbed through the epidermis and produces higher parent oestrogens serum concentrations and lower metabolites ratios because it bypasses the liver. Pharmacokinetic profiles of transdermal and oral oestradiol are very different with oral administration producing fluctuant concentrations compared to the more constant levels achieved with transdermal formulations (Kopper et al. Interestingly, there is no pharmacokinetic/pharmacodynamic relationship between serum levels and positive effects of oestradiol treatment. It has been clearly shown that serum level after transdermal oestradiol does not predict the outcome when treating hot flushes (Steingold et al. This was shown to affect the synthesis of various oestrogen-dependent hepatic serum factors (Kuhl, 2005), including coagulation and fibrinolysis factors, resulting in blood coagulation activation (Scarabin et al. Genetic polymorphisms modulating liver metabolism and first pass effect of oestrogens. This original finding deserves further investigations in largest and independent series of women receiving oral 17β-oestradiol as well as other oestrogens with different metabolic pathways, not only to treat postmenopausal symptoms but also for contraception. Taking into account the proportion of women using exogenous hormone therapy, these new results may have important clinical implications to improve the stratification of thrombotic risk and identify new groups at high risk. Conclusion the increasing life expectancy observed during the last century, without an equivalent change in the average age of menopause, resulted in an increased number of women facing the effects of low ovarian steroids for a longer period of time. Thus, the high interest towards therapeutic options capable to alleviate menopausal symptoms and the extensive research in this field are not surprisingly.

The choice and command of technique can only be mastered with continuous practice. This exercise should include both laboratory training as well as the work in the operating room.

In case of a right-handed suroperation ¨eld, so as to allow relaxed posture geon the majority of instruments are passed and optimal visualization of all the necessary to the right hand. With modern microscopes equipped with high quality video cameras this can be easily achieved. Monitors showing real time microsurgery to the anesthesiologist, the operating room nurses, and the technicians are essential and enhance teamwork and co-ordination. The progress of the operations, moments of crucial dissection or intervention, and timing for use of bipolar coagulation are essential reasons for such audiovisual equipment. Live or real-time teaching of a large number of residents and visitors is made possible by video monitors. Recording facilities for still photos and videos can be used for teaching and lecturing purposes, as well as documentation.

The neurosurgeon may also adjust height by 3 to 4 cm by high-heeled clogs (by wearing the greatest disadvantage of standing to operthem or not) – platforms are seldom necessary. Sitting is preferable in certain instances, for example, during bypass operations when the operative area is very small and the angle of vision does not have to be changed. Standing position does not a©ect the stability of the hands compared to the sitting position if a proper armrest is used (Figure 4-3). Standing position allows freedom of as desired to ne-tune the surgeon‘s height movement – even acrobatics!

Here we list the most important tools, some of which are necessary, some very useful adjuncts of Helsinki style microneurosurgery. Operating microscope A highly mobile operating microscope is the most essential tool of modern microneurosurgery. High magni¨cation, powerful illumination, and stereoscopic vision constitute the primary assets of the operating microscope. A surgical ¨eld can be viewed at great depth, in sharp focus and stereoscopically. This is essential and facilitates operation at great depth and without a ¨xed retraction system. Mirrors or endoscopes can be used to see structures hidden from view of the microscope. The counterweight-balanced microscope was designed by Yaşargil, and copFigure 4-6.

For the mouthproach, it is mostly used after the placement switch, two surgical masks are placed on each of the last dural hitch suture and for all the other before gently biting on the mouth switch.

They represent cells in Mcer have 40 to 80% cure rates using chemotherapy phase and S-phase and deﬁne the proliferative characalone or chemotherapy plus surgery or radiation (Table teristics of normal and tumor cells. For this purpose cure is deﬁned as the disappearance of any evidence of tumor for several years and a the Tumor Cell Cycle high actuarial probability of a normal life span. Patients with other types of unresectable cancer also the duration of the S-phase in human tumors is 10 to 20 may beneﬁt from chemotherapy, as evidenced by prohours. This period is followed by the G2-phase, or period longation of life, shrinkage of tumor, and improvement of preparation for mitosis, in which cells contain a in symptoms. The G2-phase lasts lial and breast carcinomas, oat cell (small cell undifferonly 1 to 3 hours for most cell types, with mitosis itself entiated) carcinoma of the lung, and acute myelocytic lasting approximately 1 hour. Cancers that are for the most part resistant to then enter the G1-phase, whose duration varies from today’s agents include melanoma, colorectal and renal several hours to days. The G1-phase also can give rise to carcinomas, and non–oat cell cancers of the lung. The factors that inﬂuence daughter cells to enter the G0, or resting the normal cell cycle consists of a deﬁnable sequence of stage, are not well understood. The ability to cause such events that characterize the growth and division of cells resting cells to reenter the cell cycle would be quite useand can be observed by morphological and biochemical ful, since proliferating cells generally are more sensitive means. Age Type of Cancer Unfortunately, many human cancers have a large Childhood Acute lymphocytic leukemia Burkitt’s sarcoma proportion of cells in the resting phase, and these cells Ewing’s sarcoma are also resistant to the class 3 agents, which include cyRetinoblastoma clophosphamide, dactinomycin, and ﬂuorouracil. Rhabdomyosarcoma this classiﬁcation of anticancer drugs has inherent Wilms’ tumor limitations. For instance, it may be difﬁcult to generalize Adult Hodgkin’s disease Non-Hodgkin’s disease about the phase speciﬁcity of a particular drug, since Trophoblastic choriocarcinoma this may vary among cell types. Several techniques are Testicular and ovarian germ cell cancers available to synchronize cell populations in such a way that most cells will be in the same phase of the cell cycle. After synchronization, one can treat cells in each phase and determine their relative sensitivity to drugs classiﬁcation divides the anticancer drugs into three catthroughout the cell cycle. This inhibition of cell cycle progression plateau in cell kill with increasing dosages. Such a dosage regimen would increase increasing tumor size is related both to a decrease in the the number of tumor cells exposed to the drug proportion of cancer cells actively proliferating (termed during the sensitive phase of their cell cycle. Class 3 agents kill proliferating cells in preferloss due to hypoxic necrosis, poor nutrient supply, imence to resting cells. However, the growth fraction, or percentage of cells in the cell cycle, is the most important determinant of overall tumor enlargement. The doubling times of human tumors have been estimated by direct measurement of chest radiographs of lesions or palpable masses G2 to be 1 to 6 months. The growth fraction indicates dividing cells that are potentially sensitive to chemotherapy; thus, it is not surG1 M (mitosis) prising that tumors with high growth fractions are the G0 ones most easily curable by drugs. Other patients respond mor decreases, and the greater the distance of cells from initially, only to relapse. Tumors of chemotherapy is instituted for a human cancer that has a the same type and size will vary in their responsiveness low growth fraction.

Drugs used in Acid-peptic disease: Acid-peptic disease includes peptic ulcer (gastric and duodenal), gastroesophageal reflux and Zollinger – Ellison syndrome. Peptic – ulcer disease is thought to result from an imbalance between cell – destructive effects of hydrochloric acid and pepsin and cell-protective effects of mucus and bicarbonate on the other side. Pepsin is a proteolyic enzyme activated in gastric acid, also can digest the stomach wall. A bacterium, Helicobacter pylori is now accepted to be involved in the pathogenesis of ulcer. In gastroesophageal reflux, acidic stomach contents enter into the esophagus causing a burning sensation in the region of the heart; hence the common name heartburn, or other names such as indigestion, dyspepsia, pyrosis, etc. They are used as gastric antacids; and include aluminium, magnesium and calcium compounds. Calcium compounds are effective and have a rapid onset of action but may cause hypersecretion of acid (acid rebound) and milk-alkali syndrome (hence rarely used in peptic ulcer disease). All gastric antacids act chemically although some like magnesium trisiolicate can also act physically. Antacids act primarily in the stomach and are used to prevent and treat peptic ulcer. H 2-receptors blocking agents such as cimetidine, ranitidine, famotidine, nizatidine. Common adverse effects: muscular pain, headache, dizziness, antiandrogenic effects at high doses such as impotence,gynecomastia,menstrual irregularities. Drug interactions may occur when it is co-adminstered with warfarin, theophylline, phenytoin, etc. Anticholinergic agents such as pirenzepine, dicyclomine Major clinical indication is prevention & treatment of peptic ulcer disease, Zollinger Ellison syndrome, reflux esophagitis. However, they are combined with H2-antagonists to further decrease acid secretion, with antacids to delay gastric empting and thereby prolong acid – neutralizing effects, or with any anti-ulcer drug for antispasmodic effect in abdominal pain. Locally active agents help to heal gastric and duodenal ulcers by forming a protective barrier between the ulcers and gastric acid, pepsin, and bile salts. Laxatives and cathartics (purgatives) Laxatives and cathartics are drugs used orally to evacuate the bowels or to promote bowel elimination (defecation). The term cathartic implies strong effects and elimination of liquid or semi liquid stool. Both terms are used interchangeably because it is the dose that determines the effects rather than a particular drug. Example:castor oil laxative effect= 4ml Cathartic effect = 15-60ml Laxative and cathartics are arbitrarily classified depending on mode of action as:. Bulk forming laxatives: are substances that are largely unabsorbed from the intestine. When water is added, the substances swell and become gel-like which increases the bulk of the fecal mass that stimulates peristalsis and defecation. Osmotic laxatives such as magnesium sulfate, magnesium hydroxide, sodium phosphate, etc. These substances are not efficiently absorbed, thus creating a stronger than usual solution in the colon which causes water to be retained. Individual drugs are castor oil, bisacodyl, phenolphthalein, cascara sagrada, glycerine, etc. It lubricates the intestine and is thought to soften stool by retarding colonic absorption of fecal water. To empty the bowel in preparation for bowel surgery or diagnostic procedures (saline or stimulant) 4. To accelerate excretion of parasite after anthelmintic drugs (saline or stimulant) have been administered. Are used in the treatment of diarrhea, defined as the frequent expulsion of liquid or semi liquid stools → hinders absorption of fluids and electrolytes. Antidiarrheal drugs may be given to relive the symptom (non-specific therapy) or may be given to treat the underlying cause of the symptom (specific therapy). They decrease diarrhea by slowing propulsive movements in small and large intestine. Species can be treated by antibiotics (ampicillin, chloramphinicol, colistin, co-trimoxazole etc. Nausea is an unpleasant sensation of abdominal discomfort accompanied by a desire to vomit. Vomiting is the expulsion of stomach contents through the mouth Nausea may occur without vomiting and vomiting may occur without prior nausea, but the two symptoms most often occur together. To a certain extent, vomiting is a protective mechanism which can result from various noxious stimuli. Drugs used in nausea and vomiting belong to several different therapeutic classifications. Peripherally metoclopoamide stimulates the release of acetylcholine, which in turn, increases the rate of gastric emptying (used in esophapeal reflux) Indication as chlorpromazine. Scopolamine, an anticholinergic drug is very effective in reliving nausea & vomiting associated with motion sickness. Drugs used to induce vomiting In case of poisoning with noncorrosive agents, and assuming incomplete absorption of the poison has taken place, induction of vomiting can be carried out the drug used for this purpose is emetine, the active ingredient of ipecacuanha (syrup of ipecac). Drugs used in the treatment of haemorrhoids Haemorrhoids are varicose veins of the anal canal which can be very distressing for the sufferer. There is no pharmacological cure for this disorder, which is often self-limiting, if not, may require surgical intervention. Stool softeners may alleviate constipation; lessen straining which can worsen the condition. Drugs used in inflammatory bowel disease (ulcerative colitis and crohn’s disease). Ulcerative colitis is an inflammatory condition of the rectum and colon; crohni’s disease can involve the whole intestine. In the absence of adequate iron, small erythrocytes with insufficient hemoglobin are formed resulting in microcytic hypochromic anemia. Nutritional deficiency Low intake of iron containing foods, reduced absorption as a result of mucosal damage, coadministration of drugs that chelate iron. Pharmacokinetics of Iron Daily requirement of Iron Male 10mg Female 15 mg Increases in growing children, pregnant and lactating women Sources Dietary mostly in the organic form from meat, cereals, etc. Body composition of Iron Total content of Iron in the body is about 4000mg in an adult male, of which about 2/3 – 2500 mg is present in circulating red blood cells see table. Table: Iron distribution in normal adults Iron content (mg) Men Women Hemoglobin 3050 1700 Myoglobin 430 30 Enzymes 10 8 Transport (transferin 8 6 Storage (ferritin and 750 300 other form) Total 4246 2314 N. The above estimations are based on the assumptions that: 96 the average male adult weighs 80 kg and has a mean Hb level of 16 g/dL and the female adult weighs 55 kg and has a mean Hb level of 14 g/dL. Iron crosses the stinal mucosal cell by active transport; then according to mucosal iron store, it can either be available to transferrin to be transported to plasma or be stored in the mucosal cell as ferritin. Storage: Iron is stored primarily as ferritin in intestinal mucosal cells and in macrophages in the liver, spleen and bone. Elimination: Very small amount are execrated in stool by exfoliation of intestinal mucosal cells and trace amounts are execrated in bile, urine and sweat with total daily excretion not more than 1mg/day. Treatment of iron deficiency anemia consists of administration of oral or parenteral iron preparation. Oral Iron Therapy: Only ferrous salts should be used because of most efficient absorption. Ferrous sulfate, ferrous gluconate, ferrous fumarate are the most commonly used oral iron preparations. About 25% of oral iron given as ferrous salt can be absorbed; therefore 200-400mg elemental irons should be given daily to correct iron deficiency most rapidly. Side effects: Oral iron therapy can cause nausea, vomiting, epigastric discomfort, abdominal cramps, constipation and diarrhea. Parenteral iron therapy: Should be reserved for patient unable to tolerate or absorb oral iron. Patients with extensive chronic blood loss who can not be maintained with oral iron alone including patients with various post gastrectomy conditions, previous small bowel resection, inflammatory bowel disease involving proximal small bowel and malabsorption syndromes need parenteral iron therapy. Intravenous administration may result in very severe allergic reactions and thus should be avoided if possible. Side effect: include local pain, tissue staining, headache, light headedness, fever, arthralgia, nausea, vomiting, urticaria, back pain, bronchospasm, and rarely anaphylaxis and death. Acute iron Toxicity Is exclusively seen in young children who ingest a number of iron tablets and rarely seen in adults as a result of suicide or repeated blood transfusions. Signs and symptoms Necrotizing gastroenteritis with vomiting, abdominal pain and bloody diarrhea, shock, metabolic acidosis, coma Treatment Whole bowel irrigation. It is mainly obtained from animal products and serves as a co factor for essential biochemical reaction in humans. Excess vitamin B12 is transported to the liver for storage and excreted in the urine. Clinical uses Vit B12 is used to treat or prevent deficiency of vit B 12 Deficiency of Vit B 12 results in: Megaloblastic anemia Neurological syndrome involving spinal cord and peripheral nerves Causes: the causes for Pernicious anemia are defective secretion of intrinsic factor necessary for absorption of vitB 12, partial or total gastrectomy, diseases that affect distal ileum, malabsoption syndrome. Almost all cases of vit B12 deficiencies are caused by malabsorption Treatment Vit B12 therapeutic preparations are cyanocoblamin and hydroxycobalamin and For intrinsic factor deficiency the vitamin should be given parenterally and patients with pernicious anemia will need life-long therapy. Body stores of folates are relatively low and daily requirement is high and hence folic acid deficiency and magaloblasitc anemia can develop within 1 -6 months after the in take of folic acid stops. Congenital malformation in newborn like spina bifida are also consequences of folate deficiency during pregnancy. Causes Dietary deficiency, alcoholics with liver disease, hemolytic anemia, malabsorption syndrome, patients with cancer, leukemia, myeloprolferative disorders, chronic skin diseases, patients on renal dialysis and patients on drugs that impair absorption or metabolism. B Folic acid supplementation to prevent folic acid deficiency should be considered in high-risk individuals including pregnant women, alcoholics and patients with hemolytic anemia, liver disease, certain skin disease, and patients on renal dialysis. Drugs used in Disorder of coagulation Introduction Hemostasis is spontaneous arrest of bleeding from a damaged blood vessel. Steps: Vascular injury Æ vasospasmÆ platelate adhesionÆ platelate aggregation Æ coagulation cascadesÆ fibrin formation Anticoagulants are the drugs which inhibit fibrin formation. Oral therapy is ineffective because it is inactivated by gastric acids and absorption is minimal because of large molecular size. Heparin must never be administered intramuscularly because of danger of hematoma formation at injection site. It is the most widely used coumarin anticoagulant and may be considered to be the drug of choice as an oral anticoagulant. The anticoagulant prevents reductive metabolism of the inactive vitamin K epoxide back to its active form Pharmacokinetics:. Clinical uses Prevention and treatment of deep vein thrombosis, treatment of atrial fibrillation with thrombus formation, prevention and treatment of pulmonary embolus, as part of the treatment of coronary occlusion and prevention of thrombus formation after value replacement Side effects Birth defect in pregnancy, hemorrhagic disease of newborn, hemorrhagic infarcts and cutaneous necrosis Contraindications – similar to heparin and the drug should never be administered during pregnancy. Drug interactions the effect of warfarin will be increased when it is used with the following drugs. All thrombolytic agents currently in use act directly or indirectly as plasminogen activators. Streptokinasea protein synthesized by streptococci, combines with plasminogen to convert it to active plasmin. Urokinase-human enzyme synthesized by the kidneys that directly converts plasminogne to active plasmin c. Anistreptase (Acylated plasminongen -streptokinase activator)bacterial streptokinase plus human plasminogen d. Indications: Multiple pulmonary emboli, central deep vein thrombosis and acute myocardial infarction. Adverse Reactions: Bleeding and allergic reactions are most common adverse effects thrombolytics. Contra-indications: Severe hypertension, recent cranial trauma and history of cerebrovascualr accident. Agents generated within the platelets and interact with the membrane receptors. Drugs that antagonize this pathway interfere with platelet aggregation and prolong bleeding time. It inhibits the synthesis of thromboxane A2 by irreversible acetylation of the enzyme cyclo-oxygenase. Therapeutic Uses: Prophylaxis against myocardial infarction and prevention of stroke in patients at risk. Aspirin is the drug of choice for treating the majority of articular and musculoskeletal disorders. Pharmacokinetics: the salicylates are rapidly absorbed from the stomach and upper small intestine. The acid medium in the stomach keeps a large fraction of the salicylate in the nonionized form, promoting absorption. Aspirin is absorbed as such and is rapidly hydrolyzed to acetic acid and salicylate by esterases in tissue and blood.
