Seizure and Epilepsy Learning objectives: at the end of this lesson the student will be able to: 1. Definition: Seizure is a paroxysmal event due to abnormal excessive discharge of cerebral neurons. Depending on the distribution of the discharge, the manifestations may be: Motor Sensory Autonomic or Psychiatric manifestation. Epilepsy is a syndrome characterized by recurrent (two or more) unprovoked seizure attacks, due to a chronic, underlying process in the brain. This definition implies that a person with a single seizure, or recurrent seizures due to correctable or avoidable circumstances, does not necessarily have epilepsy. International classification of seizures: Epileptic seizures can be classified in many different ways. Commonly used classification is the one developed by International League against Epilepsy. This classification is useful in understanding underlying etiology, selecting appropriate treatment and understanding the prognosis of seizure type. Analysis of 468 epileptics seen in neurology clinics of Addis Ababa showed highest incidence in males aged 11-20 years. The commonest type of seizure was found to be grand mal seizure accounting for 60% of all cases. Etiology of seizure or risk factors: The causes of epilepsy/seizure are vary greatly in different age groups and across different regions of the world Idiopathic or cryptogenic: in which the cause is unknown, accounts for the majority. Partial Seizures: these are seizures, which arise from localized region of the brain. This seizure activity may spread over one side of the body (Jacksonian march) to involve larger body part. The patient is unable to respond appropriately to visual or verbal commands during the seizure, and has impaired recollection or awareness of ictal phase. These are usually tonic-clonic type and difficult to differentiate from primary generalized tonic-clonic seizure. Generalized seizures There are seizure disorders which arise from both cerebral hemispheres simultaneously, with without any detectable focal onset. After 10 20 seconds the tonic phase evolves to clonic phase characterized by bilateral jerking clonic movement involving the whole body. Patients gradually regain consciousness over minutes to hours, and during this transition there is typically a period of postictal confusion, headache, muscle ache and fatigue that can last for many hours. Complications Status epilepticus Accidents Hypoxic brain damage Mental retardation and impairment of intellectual function Sudden death Psychosocial (Social stigma). Diagnostic approach/Evaluation Patients history and physical examination can aid in the determination of whether or not a seizure or some other transient event was responsible for the patients symptoms History should include: - History of the event Presence of any prodromal symptoms Description of seizure by reliable observer 527 Internal Medicine Post ictal symptoms Urinary incontinence, myalgia and tongue bite or oral lacerations are clues to the proper diagnosis. Differential Diagnosis for Seizure Syncope Psychogenic seizure (hysteric conversion) Transient Ischemic attack Migraine 528 Internal Medicine Management: Goal of therapy: Complete control of seizure Prevent development of complications and socioeconomic consequences. Avoidance of precipitating factor Maintain normal sleep schedule Avoid taking excess alcohol Reduce stresses using, physical Exercise, meditation or counseling 3. General principles: An attempt is usually made to prevent subsequent seizure using a single agent, in order to limit side effects. The addition of a second drug is associated with worsening of adverse effects; hence care should be taken, before one decides to add a second drug to the original regimen. Phenytoin: is the usual prescribed as a second line drug in resource limited settings like ours mainly because of its availability and cost. It is often given for the treatment of partial seizure Dosage: a low initial dosage with gradual increase is advised. Side effects Aplastic anemia Dizziness drowsiness 531 Internal Medicine Skin rash Transient diplopia When to stop antiepileptic drugs? The more severe and long lasting a patients active epilepsy before remission, the greater the risk of relapse. When to refer patients to a neurologist or tertiary level hospital Failure to respond to treatment Recurrence of previously controlled seizure Change in clinical pattern of seizure Appearance of previously absent symptoms/sign Development of side effects of a drug 4. Surgical interventions include Temporal lobe resection Corpus callosum sectioning Status epilepticus A condition characterized by continuous or repetitive discrete seizure with impairment of consciousness during interictal period, which lasts for more than 30 minutes. Patients may have mild clonic movement of only the fingers, or fine, rapid movement of the eyes. Complications of Status epilepticus: Aspiration Hypoxia Metabolic acidosis Hypotension Hyperthermia Rhabdomyolysis and associated myoglobinuria Multiple physical injures including vertebral bone fracture Irreversible neuronal injury Management 1. Parkinsons Diseases and other movement disorders Learning objectives: at the end of this lesson the student will be able to: 1. Parkinsonism: Definition: Parkinsonism is a clinical syndrome characterized by:- Bradykineisa: slowness and paucity of movement Tremor: This occurs at rest Rigidity Snuffling gate and Flexed posture Etiologies: 1. These degenerative changes are believed to be due to accumulation of the presynaptic protein -synuclien. Bradykinesia/akinesia: It is the most disabling feature which interferes with all aspects of daily living. Patients have trouble in walking, rising from seated position, turning over in bed, dressing etc. Brief regular interruption of resistance during passive movement may give rise tocogwheels rigidity. Pharmacotherapy of motor symptoms: Therapy to control motor symptoms should be initiated as soon as the patients symptoms begin to interfere with the quality of life. This drug has minimal effect on symptoms when used as monotherapy or as an adjuvant to Carbidopa/levodopa. Advanced Therapy c) Levodopa/Carbidopa Formulation (Sinemet, Atamet) Levodopa: is converted to dopamine by presynaptic neuron and therefore increase the amount of neurotransmitter available to the post synaptic dopamine receptor. Some of the neuroprotecitve treatment trails arte Non steroidal anti-inflammatory agents Estrogens replacement therapy in post menopausal women Selegilline therapy delays the need for levodopa therapy by 9 -12 months in newly diagnosed patients. Studies demonstrated that patients who remain on Selegilline for 7 yrs experienced slower motor decline. Therapy of non motor symptoms Insomnia due to nocturnal akinesia : treated with night time supplemental dose of Carbidopa /levodopa Depression : Responds to anti depressants like Amitriptyline Psychotic patients: first remove anticholinergics and amantadine if the patient is taking. If still the patient has psychotic symptoms and signs, start antipsychotics with minimal extrapyramidal side effects.

In 2009 the Scottish Diabetes Survey indicated there were 27 generic apcalis sx 20 mg mastercard erectile dysfunction which doctor to consult,363 patients with type 1 diabetes in Scotland discount 20mg apcalis sx mastercard what is erectile dysfunction wiki answers. Non-type 1 diabetes is being recognised with increasing frequency, particularly emerging molecular forms of diabetes, diabetes secondary to pancreatic disease and a rise in type 2 diabetes and other insulin-resistance syndromes in the young. While there are known antibody markers of prediction in high risk subjects, there is no evidence for effective methods of prevention of type 1 diabetes. The evidence on the role of the intensification of therapy in the attempt to achieve as rapid as possible normoglycaemia is inconsistent. In particular, there is no evidence of a sustained effect of any specific insulin therapy on glycaemic control during the first few months after diagnosis. Therefore, no recommendation can be given for the most appropriate insulin therapy at diagnosis. Thus, there is no agreed single target for 1+ glycaemic control in these patients. The guideline development group concluded that identifying a single target for all people with type 1 diabetes was not appropriate, but that patients should discuss this with their healthcare professionals, in the knowledge that the overall aim is to achieve the lowest HbA1c as possible, which does not interfere with the patients quality of life. B Intensive insulin therapy should be delivered as part of a comprehensive support package. While there is no evidence on the most effective form of support package, in general this refers to increased contact between patients and their families with a local multidisciplinary team of health professionals delivering specific healthcare strategies. Both basal (eg, glargine and detemir) and rapid-acting (eg, lispro, aspart and glulisine) insulin analogues are prescribed widely in the management of type 1 diabetes. Rapid-acting insulin analogues in adults In comparison with regular human insulin and as part of a basal bolus regimen, short-acting insulin analogues have a small but statistically significant effect on HbA1c in people with type 1 diabetes, with a reduction of approximately 0. Some studies have reported a reduction in hypoglycaemia in association with their use, however there is considerable heterogeneity between these studies, making it difficult to draw firm conclusions. The use of insulin analogues has been associated with an improvement in treatment satisfaction scores in several, though not all, studies which used a validated assessment tool. B An intensified treatment regimen for adults with type 1 diabetes should include either regular human or rapid-acting insulin analogues. The first meta-analysis, undertaken by the Canadian Agency for Drugs and Technologies in Health, concluded that use of glargine was associated with a reduction in HbA1c of 0. Comparison of insulin detemir and insulin glargine In a 52 week study comparing insulin detemir and insulin glargine as the basal component of a basal bolus regimen in 443 patients with type 1 diabetes, there was no difference or change + 1 in HbA1c or rates of hypoglycaemia between the groups. According to the study protocol, two thirds of the detemir group completed the study on twice daily detemir. Even these few are of relatively short duration, and most involve small numbers of subjects. One systematic review identified four studies in pre-pubertal children and one study involving adolescents which showed no difference in glycaemic control (as measured by HbA1c) between 1++ the use of rapid-acting insulin analogues and regular human insulin. One study showed reduction in rates of both overall and nocturnal hypoglycaemia when using rapid-acting insulin analogues. In developed countries its usage is increasing in patients with type 1 diabetes, who are expert at carbohydrate counting or have undertaken an appropriate structured education course. Concern has been raised over the lack of independently funded studies to allow objective comparison of results. Such studies should not restrict entry on the basis of hypoglycaemia and should use a validated QoL assessment. Progress against targets should be monitored and, if appropriate, alternative treatment strategies should be offered. B Dietary advice as part of a comprehensive management plan is recommended to improve glycaemic control. No studies were identified looking at the impact of self or carer care compared to routine care on length of stay or patient satisfaction. There are several different methods of providing advice and support to those diagnosed with type 1 diabetes in Scotland. Transition models have evolved according to local circumstances and beliefs 4 and their complexity makes comparison very difficult. There is little evidence available on the different adolescent transition models and their benefits and there is no evidence to recommend a particular transition model. Some common themes appear in the literature: Patients and their families favour a structured transition from paediatric to adult services together with adequate information along the way. Those adults responsible for them during school hours may not be experienced 3 in the care of children with diabetes. Complications such as hypoglycaemia and poor glycaemic control may occur during these times. The first study involved school-based consultations from the diabetes nurse, but was described as a pilot study, with no control group 2- and a self-selected intervention group. The intervention consisted of increased visits during 1- school hours to discuss diabetes and advice on dose adjustments. Intensification of diabetes management requires increased monitoring and insulin use and, as this significantly improves glycaemic control, should be available to all children while at school. Children at school should be supported with all necessary aspects of diabetes care, such as glucose monitoring, insulin injection and treatment of hypoglycaemia. Improvements in blood glucose control are associated with + 229,230 1 improvements in quality of life, providing there is no increase in hypoglycaemic symptoms. For clarity and simplicity the guideline development group suggests 12 years of age in both boys and girls. Recommendations for screening patients with type 1 diabetes for retinopathy, nephropathy and hypertension are included in sections 10. There is no evidence that routine screening for autonomic neuropathy or hyperlipidaemia are of benefit in children and adolescents with type 1 diabetes. C Patients with cystic fibrosis should be screened annually for diabetes from 10 years of age. C Young people with diabetes should be screened for thyroid and coeliac disease at onset of diabetes and at intervals throughout their lives. Standard blood tests exist to screen for thyroid and coeliac disease but there are limited data to support the specific frequency of screening. People with type 1 diabetes: should have the right to choose not just the insulin regimen, but whether to use an analogue (designer insulin), human or animal insulin. People with diabetes must appreciate the time action profiles of their type of insulin, have knowledge of injection sites and absorption rates of insulin. Ideally all of the above should form part of an education programme provided locally by the Diabetes Team, with the aim to empower patients to make the choice that is right for them. This will often involve the local Diabetes Team in office hours, but outwith these times arrangements vary across Scotland. Hospital admission- If you have concerns about your diabetes management as an inpatient ask the local ward staff to have the Diabetes Team review your progress. Healthcare professionals should: develop a local transition process that facilitates a seamless move to an adult service, which encourages regular attendance of teenagers. However, type 1 and 2 diabetes are high risk states for both the woman and her fetus. There are increased complications of diabetes, severe hypoglycaemia, and progression of microvascular complications.

The number of nauplii that the target organism can consume in a given period of time will have to be taken into consideration. As the antibiotic is mostly given as medicated food pellets, the food surplus not eaten by the fish, together with the drug excreted, will eventually reach the bottom around the pens. Previous research indicates that 70-80 percent of the drug ends up in the environment. Drug concentrations with antibacterial activity were found in the sediment underneath fish farm (Samuelsen, Torsvik and Erik, 1992). Their results confirm that, based on the concentration gradient of the antibacterial agents in the sediment, leaching accounts for the depuration. Variations observed in antibiotic half-lives are most probably caused by differences in water solubility and chemical- sediment interactions. In fish therapy, a strain may be resistant or sensitive depending on some additional factors: the way the antibiotic is administered, the antibiotic distribution compared with the pathogen location in the fish, and the physicochemical environment of the fish. An example of environmental influence is the well-known fact that the presence of Ca++ and Mg++ in the marine environment reduces the biological activity of oxytetracycline, quinolones, flumequine and oxolinic acid. Oxytetracycline and quinolones are reported to degrade photochemically and form divalent cationic complexes with Ca++ and Mg++ in seawater, which produces a loss of antibacterial activity in less than one month through cation complexation or binding to sediment and associated organic matter, or a combination. While the risks associated with persistence of oxytetracycline in saltwater are mitigated by complexation, when the drugs are used in freshwater, a greater fraction of the compound may exist in an uncomplexed form, and persistent antimicrobial activity in the environment could be an ever greater concern. The out-washing of oxytetracycline from the marine sediment into the water column will result in its moving from one environment where its activity is inhibited to another with an increase of biological activity (Smith and Samuelsen, 1996). The use of antibiotics in aquaculture may contribute to an increase in the frequency of resistance in the related microflora (Table 3. Horizontal transfer of resistance genes on plasmids has been demonstrated between bacteria in the water of fishponds and in marine sediments. Plasmids carrying resistance determinants have also been transferred in vitro from fish pathogens to human pathogens, including Vibrio cholerae and Vibrio parahemolyticus (Angulo, 1999). Bacteria present in aquaculture settings may be transmitted to humans who come in contact with this ecosystem. In 1991, an epidemic of Vibrio cholerae 01 infections affected Latin America; the epidemic strain in Latin America. Bacteria from the aquaculture ecosystem may also be transmitted directly to humans through handling of fish. Recently, the fish pathogen Streptococcus iniae has caused invasive infections in persons who handled store-bought aquacultured tilapia; S. Similarly, a new biotype of Vibrio vulnifcus caused hundreds of serious infections among persons handling live tilapia produced by aquaculture in Israel (Bisharat and Raz, 1996). Bacteria on fish may also be transmitted to humans when the aquacultured products are eaten, or when other foods are eaten that have been cross-contaminated by bacteria from fish. For example, Vibrio parahaemolyticus is a common food-borne disease in Japan, where infections have been linked to the consumption of aquacultured finfish (Ministry of Health and Welfare, 1999). Antibiotic-resistant bacteria have been isolated from the carcasses of catfish from the retail market (De Paola, Peeler and Rodrick, 1995). These bacteria can be transferred during food preparation at home or by handling in the market. It has to be pointed out that most of the studies mentioned above were realized under experimental conditions, which may not exactly reflect the real characteristics of aquaculture environments and realistic selection pressures. This may change as the result of mutation or by acquisition of new genetic material. Resistant bacteria can transfer the resistance to other bacteria (even to bacteria of different genera) that have never been exposed to the antibiotic, and this phenomenon is known as horizontal gene transfer. One classical horizontal gene transfer example was observed in Germany where, in 1983, some farmers started using nourseothricin for growth promotion in swine. In 1990, this resistance was transferred to farm workers, their families and citizens of the community where this antibiotic had been used, and patients were suffering urinary tract infections. Later, the resistance to nourseothricin was also observed in Shigella, a bacterium found in primates but not in swine. No nourseothricin-resistant bacteria were isolated in other parts of the country since this antibiotic had not been used elsewhere. This fact indicated that resistance from bacteria exposed to antibiotics on the farm moved to human pathogens. At the same time, the fact that one micro-organism acquires resistance against an antibiotic seems to help it in becoming resistant against others; this capacity is known as co-selection. The danger of this element is evident because it means that a single transfer event conveys resistance to several antimicrobials in the recipient bacteria. The new genetic material may be acquired by three different mechanisms: conjugation, in which a plasmid is passed from one organism to another through a pilus. This may occur between the members of same species and between bacteria from different genera or families. The integron mechanism as described has only been seen in the context of moving resistance genes, but ancestors to it have recently been discovered in Vibrio cholerae and other bacteria (Rowe-Magnus, Guerot and Mazel, 1999). Most gene cassettes encode for antibiotic resistant determinants, but antiseptic resistant genes have also described. Other types of integrons coding for other determinants in Gram-negatives have been studied, such as for biochemical functions and virulence factors, which suggests they may be implied in bacterial genome evolution (Ploy et al. These events may occur in the animal gastrointestinal tract, which serves not only as the main reservoir and major site of bacterial propagation, but also as a place for the exchange of genetic information (Wegener et al. Antibiotic resistance spreads both as a result of resistance genes spreading (infectious drug resistance) and to a major extent as a result of resistant bacteria spreading. There are two main factors that have to be considered in resistance transference: the antibiotic as a selective agent in a particular environment, and the resistant gene as the vehicle of resistance. Parameters affecting the equation equilibrium will determine the presence or absence of resistance. If both elements are kept under control, the fact that drug-resistant organisms exist does not mean that they necessarily constitute a public health problem. If the two elements are not controlled, a drug resistant trait will be selected and propagated and the environment will be populated with different kinds of resistant bacterial flora.
