Simplified Surgical Placement of Tenckhoff Catheter under Local Anesthesia: The Dammam Central Hospital Experience.

Many methods are used for the placement of Tenckhoff catheters. Eighteen consecutive Tenckhoff catheters were placed under local anesthesia through a mini laparotomy with a reduced operating team. There were only three total catheter failures.

Atypical presentation of xanthogranulomatous pyelonephritis: a case report.

Xanthogranulomatous pyelonephritis (XPN) is a rare form of chronic pyelonephritis, which is usually caused by calculous obstructive uropathy. We present a previously healthy 45-year-old housewife, who was admitted to The Dammam Central Hospital, Dammam, Saudi Arabia with left loin pain and increased frequency of micturition of four days duration. She also had icterus and features of disseminated intravascular coagulation.

Atypical presentation of Churg-Strauss syndrome: another "forme fruste" of the disease?

Vasculitis is a clinicopathologic process characterized by inflammation and damage to blood vessels. A broad and heterogenous group of syndromes may result from this process, because any type, size, and location of blood vessel may be involved. The cause of these conditions remains unclear, but an autoimmune inflammatory process, characterized by involvement of both neutrophils and endothelial cells, seems to play an important role.

[Extramembranous glomerulonephritis: clinicopathologic finding in a group of 45 Cameroonians].

Forty five Cameroonian patients in West Africa who were diagnosed as having membranous glomerulonephritis (MGN) were studied and followed up over a five year period. The mean age of these patients was 32.3 years with a female to male ratio of 5/4.

Resistant hypertension in Yaounde.

Sixty six consecutive patients with resistant hypertension were studied over a period of 12 months. During that same period 565 patients were seen in all for hypertension given an average prevalence of 11.7% of resistant hypertension.

Serological and epidemiological studies of hepatitis B and human immunodeficiency virus in a dialysis unit of Africa.

Hepatitis B infection is endemic in the tropics. Human immunodeficiency virus infection might also be endemic in parts of Africa. Blood transfusion is a major risk factor in the transmission of either virus.

[The level of plasma renin and plasma aldosterone activity in normotensive women and in pregnancy-induced arterial hypertension in a group of women from Cameroon].

Plasma renin and aldosterone activity levels were measured in a group of women from the Cameroons at various stages of pregnancy with results that were similar to the classical results already reported elsewhere. In another group of Cameroons women at term presenting with hypertension of pregnancy, the plasma renin and aldosterone activity values were the same as those found in normotensive, non-pregnant controls. However, these values were higher than those recorded in similar studies performed in Black African women.

Plasma renin activity studies in a group of African neonates and children.

Plasma Renin Activity (PRA) was determined in a group of 50 Cameroonian newborns and 50 Cameroonian children aged 1-15 years under resting conditions in order to establish baseline values, and also to investigate the relationship between PRA distribution, and blood pressure levels, age, or body weight. Mean PRA values were 0.98 +/- 0.

[Renal puncture biopsy in nephrotic syndrome in Cameroonian children, adolescent and adults: histopathologic profile according to age].

Eighty-six renal biopsies were under-taken in the Nephrology Service of the Yaounde Central Hospital (Cameroon, Central Africa) during a 4 year period (1st January 1986 to 31st of December 1989). Fifty of them (58%) were done in case of nephrotic syndrome associated or not with hypertension, renal failure. Only 42 of these 50 biopsies were valid and concerned 9 patients aged 8 to 15 years, 22 aged 16 to 30 years and 11 above 30 years.

Blood pressure profiles of a group of African children in the first year of life.

Systolic blood pressure was measured at birth, every week till 6 months, then every month till 12 months in normal Cameroonian neonates in the two Yaounde teaching hospitals. Systolic arterial pressure in awake babies rose from a mean of 65.1 +/- 1.
