This would be valuable because it is easier to measure patterns of ge- netic association than tomeasureprocesses such as immune selection or the frequency of genetic mixing order strattera 18mg fast delivery medicine emblem. However 40 mg strattera with amex symptoms 4dp5dt fet, many di?erent processes can lead to similar patternsofgenetic association order strattera 18mg medications 73, making it di?cult to infer process from pattern. Detailed data and a careful accounting of al- ternative hypotheses can allow one to narrow the possible explanations for observed patterns. The third section describes various processes of genetic mixing be- tween lineages and the consequences for genome-wide linkage disequi- librium. Some parasites have discrete, unmixed lineages, whereas other parasites recombine frequently andhavelittlelinkagebetween di?er- ent loci. New antigenic combinations have the potential to overcome existing patterns of host immunity. The fourth section presents one example of antigenic linkage dis- equilibrium, the case of Neisseria meningitidis. The immune structure of the host population could disfavor recombinant types, explaining the ob- served linkage between antigenic loci. The?fth section proposes that hosts form isolated islands for para- sites (Hastings and Wedgwood-Oppenheim 1997). Island structure con- ?nes selection within hosts to the limited genetic variation that enters with initial infection or arises de novo by mutation. Islandstructurealso enhances stochastic ?uctuations because each host receives only a very small sample of parasite diversity. As the number of genotypes coloniz- ing a host rises, selection becomes more powerful and stochastic per- turbations decline in importance. Linkage disequilibrium arises when alleles occur to- gether in individuals (or haploid gametes) more or less frequently than expected by chance. Immune pressure by hosts could potentially create linkage disequilib- rium between antigenic loci of the parasite (Gupta et al. Suppose that the parasite genotype A/B infects many hosts during an epidemic, leaving most hosts recovered and immune to any parasite genotype with either A or B. Thus, host immunity favors strong linkage dise- quilibrium in the parasites, dominated by the two strains A/B and A /B. Genome-wide linkage disequilibrium has been observed in some parasites but not in others (Maynard Smith et al. Immune pressure can create associations between di?erent antigenic loci of the parasite. But if the parasite mixes its genome by recombina- tion, nonantigenic loci will often remain in linkage equilibrium and will not be separated into discrete strains. Consider, for example, a third, nonantigenic locus with the allele C causing severe disease symptoms and the equally frequent allele C causing mild symptoms. Strong host immune pressure could potentially separate the antigenic loci into discrete strains, A/B and A /B. Butifrecombination occurs, the nonantigenic locus will be randomly associated with each strain, for example, A/B/C and A/B/C will occur equally frequently. The alleles C and C will also be distributedequally within the A /B antigenicstrain. Immunity by itself does not organize the entire parasite genome into discrete, nonoverlapping strains(Hastings and Wedgwood-Oppenheim 1997). The distinction between antigenic and genome-wide linkage is impor- tant for medical applications. If genome-wide linkage occurs, then each strain de?nes a separate biological unit with its own immune interac- tions, virulence characteristics, and response to drugs (Tibayrenc et al. Strains can be typed, followed epidemiologically, and treated based on information from a small number of identifying markers of the genome.

Flexural eczema: starts at 3-4 years order 40 mg strattera medicine you can give cats, affecting the flexure surface of elbows cheap strattera 10mg otc permatex rust treatment, knees and nape of neck (thickening and lichenificaiton) discount strattera 25mg visa medications that cause weight gain. In adults any part of the body may be affected with intense itching, particularly at night. Note: Eczema may evolve through acute (weepy), subacute (crusted lesions), and chronic (lichenified, scaly) forms. Choice of skin preparations depends on whether lesions are wet (exudative) or dry/lichenified (thickened skin with increased skin markings). Where large areas are involved give a course of antibiotics for 5-10 days (as for impetigo) After the lesions have dried, apply an aqueous cream for a soothing effect. Use the mildest topical corticosteroid which is effective, start with: C: Hydrocortisone 1% cream for wet, ointment for dry skin. Striae, acne, hyperpigmentation and hypopigmentation, hirsutism and atrophy may result. Treatment If acute (existing for less than 3 months), exclude drug reactions. If no improvement after 1 month or chronic problem, refer to specialist for combination therapy (H1, H2 inhibitors). Treatment Sun exposure to the lesions for half an hour or one hour daily may be of benefit C:Crude Coal tar 5% in Vaseline in the morning Plus C:Salicylic acid 5% in Vaseline to descale Plus C: Betamethasone ointment 0. If not responding well, refer to specialist for appropriate systemic treatment with methotrexate, cyclosporine, azathioprine etc. Cardinal signs: diarrhea, dermatitis (sites exposed to sun and pressure) and dementia. Important skin findings include: Casal’s necklace; hyperpigmented scaling involving the neck region Hyperpigmented scaly lesions on sun exposed areas Treatment Treat both adults and children with: C: Nicotinamide (O) 500mg once daily for four weeks or until healing is complete; Children give 5mg/kg per day for children. Advice on Diet: the diet should be rich in protein (meat, groundnuts, and beans) 6. Clinical features include depigmentation of patches of skin that occurs on the face, neck, trunk and extremities Treatment There is no cure for vitiligo, but there are a number of treatments that improve the condition. Treatment options generally fall into four groups: Sub block Skin camouflage Corticosteroids Depigmentation Note: Counsell the patient about the condition 6. It is characterized by sweating, weakness, headache, anorexia, fever, malaise, arthralgia, weight loss, and pain in the limbs, back and rigorous. Treatment Adults: A: Doxycycline (O)100mg once daily for 4 weeks Plus A: Co-trimoxazole (O) 960 mg every 12 hours for 4 weeks. Primary lesions are characterized by violaceous, shiny flat topped papules which may coalesce and evolve into into scaly plaques distributed over inner wrists, arms and thighs as well as sacral area. Scarring alopecia may result from lichen planopilaris (severe) Treatment A: Chlorpheniramine (O) 4mg 6 hourly Plus A:Betamethasone valerate ointment 0. One useful approach is to separate predictable reactions occurring in normal patients from unpredictablereactions occurring in susceptible patients. Predictable adverse reactions Overdosage (wrong dosage or defect in drug metabolism) Side effects (sleepiness from antihistamines) Indirect effects (antibiotics change normal flora) Drug interactions (alter metabolism of drugs; most commonly the cytochromeP-450 system) Unpredictable adverse reactions Allergic reaction (drug allergy or hypersensitivity; immunologic reaction to drug; requires previous exposure or cross-reaction). Clinically, one must learn which reactions are most likely to produce certain findings.

The views expressed in documents by named authors are solely the responsibility of those authors. Humanistic approaches to health of the whole family, broad-based care of the person rather than focusing on the disease, and improvement of quality of life are some pertinent concerns of the discipline. The family physician now functions as the core of the health care system in many countries. In countries of the South-East Asian Region, Nepal, Sri Lanka and Thailand have introduced this discipline as a full-fledged specialty, while several others have expressed interest in developing it. The current trend towards specialization with advanced technology, combined with decentralization and community-based care in countries of the South-East Asia Region, has enhanced the need for a specialty that cuts across territorial boundaries of the traditional specialties in order to promote primary care in the district health system. The Scientific Working Group Meeting for the Development of a Core Curriculum in Family Medicine for the South-East Asia Region was held in Colombo, Sri Lanka, from 9 to 13 June 2003. Twenty-seven representatives from 7 countries in the Region, including specialists in family medicine / general practice, specialists in m edical education, decision makers in universities and ministries of health, and representatives of national medical associations or medical councils, participated in the meeting. The main objectives of the meeting were: (1) To identify the status of family medicine and general practice as an academic discipline in Member Countries; (2) To formulate basic principles for a core curriculum in family medicine at undergraduate and specialist levels, and (3) To recommend specific mechanisms for promotion of family medicine programmes. Page v Executive Summary Representatives from each participating country presented the current status of training in family medicine at both undergraduate and postgraduate levels. Group discussions focussed on core curricula for three levels of practices: basic medical education; intermediate diploma level of post- graduate specialization; and full specialist level. Although several countries in the region do not have separate departments of family medicine in their medical schools, it was agreed that basic medical graduates must have several competencies that fall within the domain of family medicine. Thus, the core curriculum for family medicine was defined in such a way that it could be achieved through currently existing structures. Learning objectives relevant to the discipline of family medicine and the core content areas were identified. Recommendations were made regarding the sequence of teaching, teaching-learning methods, and methods of assessment. For post-graduate education at intermediate level, at present the period of training is 1 – 2 years in Bangladesh, India, Myanmar, Sri Lanka and Thailand. Flexibility in the duration and nature of the training programme was strongly recommended, based on the variable nature of employment for prospective candidates. Recruits should have a basic medical degree and a license to practice medicine from the national licensing authority. Recommendations were made regarding the competencies expected at this level of specialization, the relevant content areas that should be included in the training programme, and the procedural skills that should be mastered, as well as teaching-learning methods and assessments. Specialist qualifications in family medicine are usually awarded after a three-year training programme, i.
