Pediatric-onset Behçet disease in Bahrain: report of nine cases and literature review.

BACKGROUND: This report studies the clinical features of Behçet disease (BD) in children and compares our results with other international studies. METHODS: We retrospectively reviewed patient data that included the clinical picture, HLA typing, and treatment in BD cases. RESULTS: This study reviewed data from a total of nine children with BD. Median age at presentation was seven years, with a male to female ratio of 2:1. There was one patient who had Down's syndrome. Oral ulcers were present in all children, while genital ulcers were present in only 66% of cases. Skin manifestation was seen in 88% and uveitis in 55%. There was evidence of gastrointestinal (55%), neurological (55%), and musculoskeletal manifestations (77%). HLA B5 was positive in 66% of cases and 55% had positive family histories. Apart from gastrointestinal symptoms, our results were comparable with other studies. CONCLUSION: Awareness of BD symptoms in the pediatric age group is crucial for early diagnosis and treatment. The coexistence of BD and Down's syndrome needs further genetic study, which may link these two major disorders.

Renal biopsy findings in the kingdom of bahrain: a 13-year retrospective study.

Glomerular diseases continue to be the leading cause of end-stage renal disease globally. Hence, it is important to recognize the pattern of these diseases in any given geographical area. A total of 498 renal biopsies performed on patients with proteinuria, hematuria and mild to moderate renal impairment during a period of 13 years (between January 1990 and December 2002) at the Salmaniya Medical Complex (a tertiary care hospital of the Kingdom of Bahrain), were reviewed and categorized. Primary glomerular disease accounted for two-third of the glomerular diseases, which in turn constituted 44.8% of all renal biopsies. The most common histological lesion was minimal change disease (30%). Focal and segmental glomerulosclerosis was the second most common lesion (23.8%) followed by membranoproliferative glomerulonephritis (14.3%). Secondary glomerular disease comprised 33.6% of glomerular diseases (22.7% of all the renal biopsies) with lupus nephritis forming the commonest lesion (38.9%) followed by diabetic nephropathy (31.9%) and hypertension (20.4%). Tubulointerstitial diseases accounted for 13.1% of all renal biopsies whereas transplant diseases were noted in 12.2%. The miscellaneous group including inadequate biopsies constituted 7.2% of all the biopsies. The results of this analysis were compared with surveys from other parts of the World.

Renal transplant pathology: bahrain experience.

A ten-year retrospective study on renal transplant biopsies performed at the Salmaniya Medical Complex, Bahrain was performed. The histological changes were classified according to Banff 1997 working classification of renal allograft pathology. A semi quantitative scoring was also given as per the guidelines. Out of a total of 26 cases, 10 belonged to hyperacute and acute forms, while 11 could be categorized to chronic sclerosing allograft nephropathy. In the remaining five, the graft pathology was unrelated to the rejection process. Despite effective management, four cases underwent nephrectomy due to severe vascular rejection. An interesting feature was recorded in two cases in whom transmural arteritis followed chronic histological changes. Presence of tubular atrophy and interstitial matrix increase were considered useful parameters for assessing the severity in cases with chronic allograft nephropathy.
