Interventions to improve psychosocial well-being for children affected by HIV and AIDS: a systematic review.

In addition to its contribution to child mortality, HIV/AIDS has a substantial impact on the psychosocial well-being of children across the globe and particularly in sub-Saharan Africa. We conducted a systematic review of the literature in order to identify studies that assess the effectiveness of interventions developed to improve the psychosocial well-being of children affected by HIV/AIDS, published between January 2008 and February 2016. Studies that were eligible for the review included male and/or female children under the age of 18 years of age, who had lost a parent to HIV/AIDS, were living with a parent with HIV/AIDS, or were vulnerable because of other social and economic factors and living in communities of high HIV and AIDS prevalence, including child and caregiver reports. Studies were included if they documented any intervention to improve the psychosocial well-being of children including psychological therapy, psychosocial support and/or care, medical interventions and social interventions, with psychological and/or social factors as outcomes. We identified 17 interventions to improve the psychosocial well-being of children affected by HIV/AIDS. Of these, 16 studies took place in eight different low and middle-income countries (LMIC), of which 6 were in southern and eastern Africa. One study took place in a high-income setting. Of the total, fifteen showed some significant benefits of the intervention, while two showed no difference to psychosocial outcomes as a result of the intervention. The content of interventions, dosage and length of follow up varied substantially between studies. There were few studies on children under seven years and several focused mostly on girls. Efforts to improve evaluation of interventions to improve the psychosocial well-being of children affected by HIV/AIDS have resulted in a number of new studies which met the inclusion criteria for the review. Most studies are specially designed research projects and not evaluations of existing services. We call for increased partnerships between policy-makers, practitioners and researchers in order to design evaluation studies and can feed into the growing evidence base.

Comparing acute and chronic human cutaneous leishmaniasis caused by Leishmania major and Leishmania tropica focusing on arginase activity.

BACKGROUND: Cutaneous leishmaniasis (CL) in Iran is mainly caused by Leishmania major (L. major) and L. tropica. Arginase mediated L-arginine metabolism is an important issue in Leishmania parasite propagation. Arginase activity in human CL due to L. major and L. tropica have not been studied up to now. OBJECTIVES: We aimed to compare the clinical and laboratory aspects of acute and chronic CL, focussing on arginase activity. METHODS: In this case-control study, 30 patients with acute CL (duration ≤ 1 year), 13 patients with chronic CL (duration ≥ 2 year) and 11 healthy controls were recruited. Arginase activity was measured in skin biopsies of lesions, peripheral blood polymorphonuclear cells (PMNs), peripheral blood mononuclear cells (PBMCs) and plasma by standard methods. RESULTS: The median of arginase activity in the acute lesions was higher than in chronic samples and significantly higher than in healthy controls (P = 0.008). PMNs of both acute and chronic patients showed higher levels of arginase activity as compared to the levels in PBMCs and plasma. The median of arginase activity in the PMNs of patients with chronic CL was higher than that of patients with acute CL and significantly higher than that of the healthy controls (P = 0.010). CONCLUSION: The level of arginase activity in lesions of patients with acute and chronic CL was higher than the skin of healthy controls. The highest level of arginase activity was observed in PMNs from patients with chronic CL. This suggests that the high level of arginase activity in PMNs of patients with chronic CL may contribute to the chronicity.

The association of pyoderma faciale and erythema nodosum.

Pyoderma facial (PF) is a sudden severe eruption of pustules and cystic swellings which may be interconnected by sinuses. It affects mainly adult women. We report the case of a 21-year-old woman presenting with sudden onset of coalescing nodules and abscesses on the face, with mild systemic disturbance. She also had erythema nodosum (EN)-like lesions on the legs. To the best of our knowledge, this is the first reported case of PF associated with EN.
