Objective: Patients with chronic hepatitis C (CHC) have a poorer quality of life than those with other chronic liver diseases. However, some of the factors that determine health-related quality of life (HRQOL) in these patients, such as the degree of liver fibrosis, are still controversial. Therefore, the aim of the present study was to investigate the impact of CHC on HRQOL by conducting clinical, psychiatric, and sociodemographic evaluations. Methods: One hundred and twenty-four consecutive patients attending a referral center for hepatitis were evaluated using the Mini-International Neuropsychiatry Interview, the Hamilton Depression Rating Scale, the Hospital Anxiety and Depression Scale, and the Medical Outcomes Study 36-Item Short-Form Health Survey. Multiple linear regression analyses were used to quantify independent associations between HRQOL and the clinical, psychiatric, and sociodemographic variables of interest. Results: Reduced HRQOL was independently associated with major depressive disorder (MDD) and with elevated levels of alanine aminotransferase, but was not associated with hepatic cirrhosis. Conclusions: MDD rather than the grade of liver fibrosis was strongly associated with HRQOL impairment in patients with CHC. These findings highlight that, in patients with CHC, the psychological effects of the disease deserve more attention and the implementation of integrated medical, psychiatric, and psychological care may be helpful.

The rough grind machine operation in metallic material produce a sub product with the followings components such as: metallic residue, small parts come from the resin grinds, diatomaceous earth material (filter material) and soluble oil in water for tools cooling. According [HU1UH] from ABNT, this sub product is toxic, not inert material, aggress the environment with pollution in the currency water and contaminate the ground when incorrectly go to the municipal solid waste. The final destination of this sub product, is the incineration, in the cements company, being the incorporated the sub product to the cement, during your production. With the qualitative result using the scanning electron microscopy (SEM), coupled to the dispersive energy spectroscopy (EDS), two experiments were made with objective to separate the magnetic material of the non-magnetic material, using a permanent magnet. We conclude that the magnetic material can be used by powder metallurgy process in production of pieces.

Foram investigados aspectos clínicos, laboratoriais, terapêuticos e evolutivos da leishmaniose tegumentar americana em Belo Horizonte. O estudo incluiu 358 pacientes com leishmaniose cutânea (LC) e 25 com leishmaniose mucosa (LM). Comparados aos pacientes com LC, aqueles com LM apresentaram maior tempo de doença e relato de outras doenças concomitantes, sugerindo que a debilitação pela leishmaniose e/ou outras doenças podem contribuir para a ativação e/ou disseminação mucosa do parasito. As sensibilidades das reações intradérmica, de imunofluorescência indireta e da pesquisa direta do parasito foram de 78,4, 79,3 e 68,3%, respectivamente. O tratamento com antimoniato de meglumina foi 100% eficaz, com 59% de efeitos colaterais ao longo do tratamento. A recidiva após tratamento ocorreu em 32 (10,1%) dos 318 casos seguidos por até dois anos. A maioria das recidivas (31 dos 32 casos) ocorreu em pacientes com LC tratados com 15mg Sb5+/kg/dia. Na investigação de critérios de cura, a reação intradérmica negativa foi o único fator associado a um risco três vezes maior de recidiva. Um aumento da dose ou do tempo de tratamento talvez melhore o prognóstico nestes pacientes.

This study investigated clinical, laboratorial, therapeutic and prognostic aspects of American cutaneous leishmaniasis in Belo Horizonte in 358 patients with cutaneous leishmaniasis (CL) and 25 with mucocutaneous leishmaniasis (MCL). Compared to CL patients, the MCL patients reported longer duration of disease and higher frequency of other diseases, suggesting that debilitation caused by leishmaniasis or other conditions might contribute to activation and/or mucous dissemination of the parasite. The sensitivity of skin test, indirect immunofluorescence reactions and direct detection of parasites was 78.4, 79.3 and 68.3%, respectively. The treatment with meglumine antimoniate presented 100% efficacy, but 59% patients had side-effects. During two years of follow-up, there were 32/318 relapses after successful treatment. Most relapses (31/32) were of CL patients treated with 15 mg Sb5+/kg/day. The negative response to skin test was the only factor associated with a significant threefold increased risk of relapse. Higher dose or longer duration of treatment might improve the prognosis in these patients.

In order to characterize the epidemiology of American Cutaneous Leishmaniasis (ACL) in a periurban area of the municipality of Sabará in the metropolitan region of Belo Horizonte (MRBH), an area until then considered free of the disease, a cross sectional survey was undertaken in 1990. The survey of the population consisted of 1119 interviews and 881 clinical examinations using Montenegro's skin test (MST). A low prevalence (3.7%) of positive MST was encountered. The disease had been occuring in the area for about 20 years in the form of sporadic cases. The predominant species of sandfly both in domestic areas and nearby areas of secondary vegetation was Lutzomyia whitmani. A canine survey of delayed hypersensitivity to the antigen P10,000 identified only one dog with a positive reaction out of 113 examined. The transmission of ACL in MRBH was confirmed. The occurrence of the disease in women, children and individuals with no contact with forest areas as well as the presence of potential vector species in the domiciliar environment, suggests the transmission of the disease in this environment.
