Dimenhydrinate

Of epilepsy in which drop-attacks are the most hazardous type of seizure. Callosotomy has been advocated as a palliative treatment option in order to reduce the severity of such seizures. We studied the clinical outcome and quality of life of LG patients undergoing callosotomy. METHODS : From September 1995 and May 2003, 23 patients with LG underwent callosotomy and of those 13 were further studied. All of them had multiple types of seizures that were refractory to medical treatment, with drop-attacks as the most severe type and were followed for at least 1 year after surgery. Demographic data, etiology, neuroimaging, VEEG, medical treatment, seizure type and family satisfaction after surgery were evaluated. RESULTS: 86% were male, onset of seizures was in infancy in the majority of patients, all had cognitive impairment, 5 patients had an unknown etiology. All were dependent on their caregivers for daily activities, such as feeding, taking their medications and walking. Drop-attacks were the most severe and disabling seizures. Interictal EEG had typical LG features and ictal VEEG had diffuse electrodecremental and generalized run of rapid spikes or generalized slow spike-and-wave. Seizure frequency reduction was 50% in 8 61.5% ; , 50% in 3 23% ; and without significant changes in 2 15.3% ; . Quality of life in the opinion of caregivers was better in 11 84.6% ; , and 10 76.3% ; patients had a fewer behavioural disorders. CONCLUSIONS: In our series, callosotomy reduced seizure frequency in the majority of patients and led to a better behavioural outcome and ditropan.

Papillary muscle dysfunction or Ebstein's anomaly of the valve is also recognised. This improves as the pulmonary artery pressure falls over the next few days. c. CHF in first week of life Serious cardiac disorders which are potentially curable but carry a high mortality if untreated, often present with CHF in the first week of life. Accordingly, a sense of urgency should always accompany evaluation of the patient with CHF in the first week. The closure of the ductus arteriosus is often the precipitating event leading to catastrophic deterioration in a seemingly healthy neonate. It follows that prostaglandins E1, now available in India ; should be utilised in such babies. Regarding CHF in this age group a few points need to be emphasised. i ; Peripheral pulses and oxygen saturation by a pulse oximeter ; should be checked in both the upper and lower extremities. A lower saturation in the lower limbs means right to left ductal shunting and occurs due to pulmonary hypertension, coarctation of aorta or aortic arch interruption. ii ; An atrial or ventricular septal defect ASD VSD ; does not lead to CHF in the first two weeks of life. Therefore, an additional cause must be sought eg. coarctation of aorta or TAPVC ; . iii ; Premature infants have a poor myocardial reserve and a patent ductus arteriosus PDA ; may result in CHF in the first week in them . iv ; Adrenal insufficiency due to enzyme deficiencies or neonatal thyrotoxicosis could present with CHF in the first few days of life. d. CHF beyond second week of life The most common cause of CHF in infants is a ventricular septal defect that presents around 6-8 weeks of age. This is because the volume of the left to right shunt increases as the pulmonary resistance falls. Although a murmur of VSD is apparent by one week, the full blown picture of CHF occurs around 6-8 weeks. Other left to right shunts like PDA present similarly. The fall in pulmonary vascular resistance is delayed in presence of hypoxic lung disease and at high altitude [7] and could somewhat alter the time course accordingly. Medical management of CHF is perhaps most important in this age group, since the VSD may close on follow up. It is equally important to understand that spontaneous improvement in CHF could result from development of obstructive pulmonary arterial hypertension, even in early childhood [8]. Left coronary artery arising from the pulmonary artery LCAPA ; , a rare disease in this age group merits separate mention, since it is curable and often missed. As the.

Longitudinal studies have demonstrated that lateral lumbar radiographic scoring of abdominal aortic calcification AAC ; is predictive of cardiovascular disease death, which suggests the possibility of using lateral VFA images for a similar purpose. Therefore, we examined how well DXA images obtained for vertebral fracture assessment VFA ; detected AAC compared to radiography in 59 women mean age 76.5 years, range 66 to 93 ; Methods: Both sets of images were blindly evaluated for AAC by a single reader using a previously validated 24-point scale. A 24-point radiographic score of R5 was considered to be significant AAC. Results: The VFA and radiograph readings showed moderate agreement intra-class correlation coefficient 0.81, 95% C.I. 0.66 to 0.90 ; . The sensitivity and specificity of a VFA score R 5 for those with significant AAC were 65% and 90%, respectively. The area under the receiver operating characteristic curve was 0.83 figure 1 ; using the VFA 24-point scale for the detection of those with significant AAC and famotidine.
Those who received HPV vaccine 89.9% ; than in those given placebo 85.5% ; . Among live births, the proportion of infants in whom a medical condition was uncovered was found to be somewhat higher in women who received HPV vaccine than in those who received placebo. Of particular importance, however, the proportions of pregnancies with known outcomes that resulted in a normal infant were comparable between the two study groups: 50% 56 112 ; in the women given HPV vaccine and 51.3% 59 115 ; in those receiving placebo. Overall, the administration of HPV vaccine was generally well tolerated among patients nine to 26 years of age. Its use was associated with an increase in side effects at the injection site and a modest increase in transient low-grade fevers, compared with placebo, all of which were of mild intensity.

Members enthusiastically. Postoperative vomiting continues to be a problem after strabismus surgery in children. Our study demonstrates that rectal application of 23 mg kg body weight dimenhydrinate given 30 minutes before the induction of anesthesia leads to approximately a 50% relative decrease of PONV and significantly reduces requirements for rescue medication during the first 12 hours after surgery, compared with placebo. Several therapies have proven effective for treatment and prevention of PONV. Rose et al. 4 ; evaluated the antiemetic efficacy of odansetron and metoclopramide in children undergoing strabismus surgery and found a reduction of PONV from 67% in the placebo group to 53% in the metoclopramide group and 30% in the odansetron group. Compared with our results, IV odansetron was only slightly more effective in reducing PONV than dimenhydrinate, whereas metoclopramide was markedly less effective. IV and oral application of droperidol were also found to lead to a significant reduction of PONV 5, 6 ; . However, the minimal effective dose without sedative side effects is still under discussion 11, 12 ; . Although in our study no direct comparison between commonly used antiemetics and dimenhydrinate was. Percutaneous gastrostomy tube for venting and a percutaneous jejunostomy tube for feeding work better in combination than alone.18 Low-fat diet. As liquid emptying is usually normal in gastroparesis, liquid nutrition should be encouraged. Fats delay gastric emptying by promoting the release of inhibitory cholecystokinin, and low-fat, high-carbohydrate meals are therefore recommended. Frequent, small, low-residue meals are preferable. Tight glucose control. In people with diabetes, optimum glucose control can improve gastric myoelectrical activity, 19 whereas glucose levels above 150 mg dL can impede gastric emptying.20 Antiemetic agents Antiemetic agents are the most widely used drugs for gastroparesis, since nausea and vomiting are the most common symptoms and also due to the relative ineffectiveness of other drug classes. The important classes are the phenothiazines, antihistamines, and antagonists of the serotonin 5-HT3 receptor. As a general rule, medications used in gastroparesis should not be considered ineffective until full therapeutic dosages have been used. Phenothiazines include prochlorperazine, trimethobenzamide, and promethazine. Elixirs and suppositories are preferable to other preparations. Long-term use is generally safe, but sedation and extrapyramidal symptoms are the important side effects. Antihistamines include diphenhydramine and dimenhydrinate. Sedation is the most common side effect of these medications. Their anticholinergic effects might occasionally worsen gastroparesis. Serotonin 5-HT3 ; receptor antagonists such as ondansetron and granisetron are very effective in controlling nausea and vomiting. They act both centrally and peripherally. They should be used only intermittently, as their long-term effects are unknown. They are also the most expensive of the antiemetic agents. Prokinetic agents Prokinetic agents TABLE 3 ; enhance gastric contractility, correct dysrhythmias, and improve antroduodenal coordination. Usually, they should be given about 30 minutes before. NV may originate after the activation of sensors detectors ; located in the gut, the vestibular labyrinths and the chemoreceptor trigger zone CTZ ; . The sensation of nausea also involves the cerebral cortex. Signals associated with lamina content and gastric tone are detected by intestinal chemo- and mechanoreceptors and reach the medulla via the vague whose afferents terminate in the nucleus tracts solitaries NTS ; . The activation of chemoreceptors is probably mediated by the local release of cartooning 5HT ; which binds to intestinal 5HT3 and 5HT4 receptors. Impaired GI motor activity i.e. post-surgery ; may also have a role in the aetiology of NV. Emesis-related afferents from the periphery terminate mainly in the NTS which contains the CTZ that can be activated by chemicals present in blood ; and the area postrema. The NTS includes several nuclei that control related functions such as swallowing, gastric tone motility, laryngeal and pharyngeal sensation, baroreceptor reflexes and respiration. It has been postulated that neurones from the NTS project to the ventral medulla, the hypothalamus and to a central pattern generator CPG ; , which would co-ordinate the sequence of events taking place during emesis. Thus, the concept of a single vomiting centre has been replaced by groups of organised neurones present throughout the medulla that would be sequentially activated and controlled by a CPG [4]. Many transmitters and receptors participate in emesis both at the periphery intestinal ; and in the CNS. Among them, the dopaminergic D2R ; , cholinergic, serotoninergic 5HT3, 5HT4 ; , histaminergic, adrenergic 2 ; , opioid MOR ; , neurokinin NK1R ; and cannabinoid CB1 ; receptors are present in brain regions associated with the vomiting reflex, and provide the basis for the antiemetic action of drugs used in the management of NV [5]. Drugs that act as antagonists of these receptors include dopamine antagonists droperidol, haloperidol ; . Low doses of droperidol are as effective as 5HT3 antagonists, but may induce severe arrhythmias and its use has been questioned by the FDA USA ; . Transdermal scopolamine is useful in motion sickness and has also proven to be beneficial in PONV. The 5HT3 antagonists ondansetron, dolasetron ; are safe and effective, their high cost being the main disadvantage. Anti-histaminics i.e. cyclicine ; are good antiemetics but induce dizziness, dry mouth and sedation, related to their anticholinergic action. Combinations of two or more antiemetics are used in the management of refractory nausea end vomiting, and have proven to be beneficial in PONV [6]. Despite the opioid induced NV being elicited by direct stimulation of MOR located in the CTZ, the vestibular component seems to be significant since opioid-induced NV is enhanced by vestibular stimulation, and opioids increase labyrinthine sensitivity to motion. Opioid antagonists naloxone, naltrexone ; reverse the emetic response induced by opioids. All MOR agonists used in clinical practise induce NV in a similar proportion. The reported incidence after acute and chronic opioid administration varies between 8-30 %, and tolerance generally develops within days to weeks. Several factors related to the route, the drug, the dose and the patient might influence the manifestation of opioid-induced emesis [7]. Multiple reports suggest that oral p.o. ; administration induces more GI effects than when given by the rectal, transdermal or subcutaneous routes. Regarding the dose, opioid-induced NV shows a poor dose-response relationship that could be related to tolerance. There are important inter-individual differences in the response to opioids, which can be explained by co-morbidity, as well as genetic variations related to the pharmacokinetics and pharmacodynamics MOR polymorphisms ; of opioids. Concerning treatment, most patients will respond to antiemetics active at the CTZ and or those used in motion sickness; there is no definite evidence suggesting the superiority of one antiemetic over another in opioid-induced emesis. Drugs that have been successfully used in cancer patients include haloperidol, prochlorperazine, dimenhydrinate, phenotiazine, scopolamine, cisapride, ondansetron, and dexamethasone. The peripherally acting opioid antagonist methylnaltrexone may antagonise opioid induced emesis, but additional clinical trials are required to demonstrate its safety and efficacy. Refractory NV can be treated with combinations of antiemetics. POSTOPERATIVE NAUSEA AND VOMITING PONV ; . The aetiology of PONV is multifactorial and may be related to patient, type of anaesthesia and surgical procedure [6]. Although the overall incidence is high about 30 % in the first 24 h postoperatively ; , PONV is self-limiting and generally remits spontaneously; nevertheless it is particularly bothersome for the patient. It may induce dehiscence of surgical wounds and have a considerable impact in healthcare cost. Children below puberty have an incidence twice as high as adults. In ambulatory surgery, about 1% of the patients are readmitted due to PONV. Predictive factors for PONV include the use of inhalation anaesthetics and opioids, the duration and type of surgery laparoscopic, strabismus, other ; , female sex, and a history of PONV or motion sickness; smokers have a lower incidence of PONV. Taking these factors into account Apfel et al [8] have designed a simple score to predict the incidence of PONV.
