A dermatologist can often diagnose scabies by visually examining a patient’s skin from head to toe.
To make sure that a patient has scabies, a dermatologist may remove some skin. This is painless. Your dermatologist will put the skin on a glass slide and look at the slide under a microscope. If y...our dermatologist sees scabies mites or their eggs, it is certain that you have scabies.

High levels of storage iron may increase malaria susceptibility. This risk has not been investigated in semi-immune adolescents. We investigated whether baseline iron status of nonpregnant adolescent girls living in a high malaria transmission area in Burkina Faso affected malaria risk during the fo...llowing rainy season. For this prospective study, we analysed data from an interim safety survey, conducted six months into a randomised iron supplementation trial. We used logistic regression to model the risk of P. falciparum infection prevalence by microscopy, the pre-specified interim safety outcome, in relation to iron status, nutritional indicators and menarche assessed at recruitment.

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

2nd edition. Children with TB comprise about 10-12% of the total TB cases diagnosed in the country. This burden is likely to be higher given the challenges in diagnosing TB in children. The symptoms of TB in children mimic those of other childhood diseases. Children do not readily expectorate and th...ey have pauci-bacillary TB hence some will be missed using bacteriological tests. The government has however introduced GeneXpert molecular testing that is more sensitive than microscopy in detecting TB. Health care workers therefore need a reference guide to obtaining sputum from children for testing. Treatment of TB in children has been reviewed and now includes Ethambutol. There are now improved paediatric friendly TB medicines for treatment of TB in children and health care workers need a reference guide to enable them accurately dispense the TB medicine to children. Malnutrition is a common predisposing factor for TB in children. On the other hand, TB predisposes children to malnutrition or worsens an existing state of malnutrition. Nutrition care and support forms an integral part of treatment for a child with TB disease.

Для создания этого отчета MSF исследовала программы и практику лечения лекарственно-чувствительного и лекарственно-устойчивого туберкулеза в восьмистранах с высо...ким бременем туберкулеза, обладающих различным набором эпидемиологических, экономических, географических и демографических характеристик (Бразилия, Зимбабве, Индия, Кения, Мьянма, Российская Федерация, Узбекистан, ЮАР). Мы исследовали ключевые показатели диагностики, лечения и доступности основных препаратов, поставок лекарственныхсредств и финансирования .
