Urolithiasis in Saudi Arabia.

In a retrospective study, 760 Saudi patients with urolithiasis were epidemiologically and metabolically studied (41% were from the Central region, 32% South, 14% West, 9% North, and 1% East; the remaining 3% were Saudi but of unknown region). The male to female ratio was 5:1; 87 percent of the patients were aged thirty to sixty years and 11 patients were under age fourteen. There was no clear relation of stone formation to occupation. Sixty-nine percent of calculi were renal, 29 percent ureteric, and only 3 percent were bladder calculi. Two hundred seventy-eight operative procedures were done (36.5% of all patients), including pyelolithotomy, nephrolithotomy, ureterolithotomy, ESWL, cystolithotomy, and extractions by basket. Infection was a rarity (6%) and urinary schistosomiasis was found in 33 patients (4.3%), 24 of whom were from a schistosoma-infested region. Raised serum calcium was found in only 5.7 percent and raised serum urate in 13 percent. Increased urinary excretion of urate was found in 60 percent and hypercalciuria in 9 percent. Seventy-six percent of stones analyzed (239) were calcium oxalate, 20.5 percent urate, and 3.3 percent phosphate.

Extracorporeal shock-wave lithotripsy (ESWL)-induced erosions in upper gastrointestinal tract. Prospective study in 40 patients.

In a prospective study in 40 patients receiving ESWL treatment, gastric and/or duodenal erosions occurred in 32 patients (80%); in 24 (60%) the erosions were in the proximal part of the stomach. There was no direct relation between the patients' weight and the development of erosions. In some patients more erosions developed in relation to the number of shock waves received and the intensity of energy given. In most patients early onset of hematuria indicated development of more erosions. To our knowledge this is the first report in the literature on ESWL-induced erosions in the upper gastrointestinal tract.

Ocular side effects of systemic steroid therapy in renal transplant patients.

Sixty-one renal transplant patients were studied for ocular complications of steroid therapy. Twenty patients (32.8%) were found to have posterior subcapsular cataract. Three patients (4.9%) had ocular hypertension. There was no significant correlation between cataract formation and the total dose of steroids, number of rejection episodes, or the period of hemodialysis. HLA-A9 was present in noncataract patients to a greater extent, a statistically significant (P less than .05) finding not reported before to our knowledge.

Brucellosis in a farming community in Saudi Arabia.

This communication describes a study of the prevalence of brucellosis in a farming community of Saudi Arabia. Standard agglutination tests of sera from 21 patients were tested for Brucella abortus and Brucella melitensis. The results show that 8 (38%) were positive with titres of 160 or over 20 480 and with titre of complement fixation tests ranging from 8 to 64. Agglutination titres of 20 to 40 were present in only 3 cases. Those patients with positive agglutination titre of 160 or higher admitted histories of consumption of raw milk. All 8 patients presented typical symptoms of brucellosis and responded to appropriate antibiotic therapy. This study suggests that farm workers and those who drink raw milk are more likely to contract brucellosis than are the general population.
