The prevalence of human papillomavirus (HPV) genotypes in relation to age was investigated by the polymerase chain reaction (PCR) method in cytologically normal smears from 4 different groups of women. Group A consisted of young women from a district population, aged 15-34 years, using oral contraceptives and visiting general practitioners for a check-up (n(More)
Tick borne relapsing fever is an endemic disease in Sengerema district, Mwanza region, Tanzania, East Africa. Five cases of neonatal relapsing fever occurring in this endemic area are described. Two neonates showed signs of septicaemia, clumping of spirochetes (Borrelia index is uncountable) in the thick blood smear and they died the day of admission. Two(More)

The diagnosis of tick-borne relapsing fever was established in 27 pregnant patients by demonstration of Borrelia spirochaetes in a thick blood smear and the borrelia index was estimated to calculate the density of the spirochaetaemia. Clinical findings are described and compared with those reported from Rwanda. The results suggest that the density of the(More)
No aetiological factors are at present known in the pathogenesis of liposarcomas. Benign lipomatous disorders, such as lipomas and lipomatosis, generally do not predispose to the development of liposarcomas. A case is presented of a patient with multicentric retroperitoneal liposarcomas, associated with retroperitoneal lipomatosis and preceded by a long(More)
Clinical findings on 25 patients with a high spirochaetemia are presented. The diagnosis was established by demonstration of Borrelia spirochaetes in the thick blood smear and a Borrelia-index was estimated to calculate the density of the spirochaetemia. Causes of death were septicaemia (3x), severe spirochaetemia in a neonate (1x), and successive relapses(More)
Tetanus is a life-threatening, preventable infection with a high mortality. Our aim was to determine the changes in incidence and case fatality rate at Sengerema Designated District Hospital in a retrospective review of patients who had been hospitalised with tetanus between 1962 and 2012. In the 1970s and 1980s a vaccination campaign was organised in order(More)
A fatal Jarisch-Herxheimer reaction developed after treatment with high doses of penicillin in a case of lobar pneumonia caused by Borrelia duttoni. Penicillin given on the first day and tetracycline on subsequent days to avoid severe Jarisch-Herxheimer reactions, has the disadvantage of a longer period of spirochetemia and hypotension as compared with(More)
Relapsing fever is a disease caused by one of the species of Borrelia. It is often misdiagnosed as malaria and can have fatal complications such as the Jarisch-Herxheimer reaction (JHR) after the commencement of treatment with antibiotics. A 19-year-old Tanzanian woman was admitted after a term home delivery that day. She presented with a 2 day history of(More)
A 31-year-old woman is reported with in the genital region multiple squamous carcinomas of the skin (buttock), vulva, vagina, anus and cervix uteri. All these carcinomas were HPV 16 positive as tested by DNA in situ hybridization. The existence of areas with normal epithelium between all tumor localisations and the absence of distant metastases indicate(More)
