A Rare Case of Pseudoangiomatous Stromal Hyperplasia in a Male Patient.

Pseudoangiomatous stromal hyperplasia (PASH) is a rare benign breast condition that can mimic the appearance of breast cancer on imaging studies.

Role of Percutaneous Glue Treatment After Persisting Leak After Laparoscopic Sleeve Gastrectomy.

Background: Over the years, many treatment modes have been attempted for gastrocutaneous fistula (GCF) after laparoscopic sleeve gastrectomy (LSG). Minimally invasive techniques for GCF treatment include stent placement and radiological percutaneous glue treatment (GT).

Material And Method: Ten patients underwent a radiological acrylate mixed with contrast medium GT combined or not with other treatment strategies such as relaparoscopy, ultrasound, or computerized tomography scan (CT scan)-guided drain and endoscopic stent placement.

Serologic markers for hepatitis B virus and hepatitis A virus in Bushmen in West Caprivi, Namibia.

A community based sero-epidemiological study was undertaken to determine the age specific prevalence rates of hepatitis A virus (HAV) and hepatitis B virus (HBV) infection in a band of Bushmen in the West Caprivi, Namibia. All children tested and all but two of the adults tested showed the presence of anti-HAV antibodies. Nineteen individuals (18%) were positive for HBsAg and 65 (61%) individuals had serologic evidence of past exposure to HBV infection.

African trypanosomiasis: haematogenic brain parasitism early in experimental infection through bypassing the blood-brain barrier, with considerations on brain trypanosomiasis in man.

A hematogenic invasion of the brain in suckling NMRI mice infected with Trypanosoma brucei rhodesiense was initiated by means of a mechanical damage of the blood-brain barrier. The brain was punctured after development of a blood infection. Brain infection was found in 31 out of 32 animals examined.

Specificity of the Testryp CATT card agglutination test in a non-sleeping-sickness area of Africa.

A card agglutination test (CATT), recently developed for the diagnosis of trypanosomiasis, has been evaluated in certain southern African localities; 179 blood specimens and 63 serum samples from black patients of both sexes and widely ranging ages, suffering from a variety of generalized and parasitic disorders, were tested. False-positives were minimal (2.9%) and there were no cross-reactions with any of the parasitic infections.

African trypanosomiasis: treatment-induced invasion of brain and encephalitis.

Histological sections of the brain from Microtus montanus infected with Trypanosoma rhodesiense and treated after the initial infection period showed that trypanosomes promptly invade the brain tissue and induce a severe encephalitis within a very short time. These findings suggest that the brain invasion and encephalitis that occur after treatment in sleeping sickness must be considered an effect of the treatment. The results illustrate that the brain invasion is probably not hematogenic but rather due to a process of parasite migration from the subarachnoidal space over the Virchow-Robin spaces into the brain.

Experimental Trypanosoma (Nannomonas) congolense infection in Microtus montanus.

Seventy-two voles (Microtus montanus) were infected with a strain of Trypanosoma congolense of low virulence in mice to study their susceptibility and value as a tool for testing chemotherapeutic agents. The infection in Microtus was highly virulent. Parasitaemia was low to moderate.

Experimental chronic Trypanosoma brucei rhodesiense infection in Microtus montanus.

Adult Microtus montanus were inoculated with a recently isolated strain of Trypanosoma brucei rhodesiense of human origin. The animals developed subacute to chronic infection and low-grade parasitemia. Histopathological examination of the heart revealed a severe pancarditis resulting in pronounced weight loss, and survival times of 5-8 weeks, preventing development of meningoencephalitis.
