The chest radiograph in brucellosis.

A retrospective study of chest radiographs in patients with brucellosis was undertaken at King Khalid University Hospital, Riyadh. The commonest presenting symptoms were fever, back and joint pains, excessive sweating, headache, and cough. Different chest radiographic abnormalities were detected, including soft miliary mottling, parenchymal nodules, consolidation, chronic diffuse changes, hilar or paratracheal lymphadenopathy and pneumothorax. Soft miliary mottling and pneumothorax have not been described before. The high incidence of lung abnormalities is most probably due to the chronicity of the disease in the present series.

Unusual presentation of culture positive brucellosis.

We have reviewed the clinical presentation of 100 consecutive culture positive cases of brucellosis which came under our care during the last two years. Of these, six had atypical presentations and but for the routine practice of sending blood for brucella culture, the diagnosis would have been missed. The unusual presentations included a 19 year old boy presenting as an acute abdomen ending in laparotomy, a 52 year old man presenting with a psoas abscess, a 29 year old woman presenting with a transient perinephric mass, a 75 year old man with an acute flare up of his osteoarthritis, a 65 year old diabetic man presenting in an insulin-resistant diabetic state and a 35 year old man presenting with a cauda equina syndrome.

Upper gastrointestinal endoscopy in Saudi Arabia: analysis of 6386 procedures.

Fibreoptic endoscopy is now established in the investigation of upper gastrointestinal disease. We report our findings in a large series of endoscopic procedures (6386) mostly in Middle Eastern Arabs, and compare the results obtained in Western patients. We find fibreoptic endoscopy to be feasible, safe, acceptable and effective.

Brucella meningitis.

Infection with Brucella melitensis is endemic in Saudi Arabia but involvement of the central nervous system (CNS) is rare. We report on three patients with acute brucella meningitis, all of whom had a history of exposure to a possible source of infection. Diagnosis was confirmed by isolation of Brucella species from blood cultures. Examination of cerebrospinal fluid revealed lymphocytic pleocytosis with a high concentration of protein and low concentration of glucose. The patients were treated by combinations of co-trimoxazole, doxycycline or rifampicin. All responded well without recurrences. A combination of two of the three drugs was effective in treating brucellosis of the CNS when given for a period of 6-8 weeks.

Spinal brucellosis.

The findings in 44 patients with back pain and brucellosis are described. Radiological changes tended to occur in older patients with a longer duration of disease. The younger patients more often experienced an acute arthritis with sacroiliitis resembling a reactive disease. Bone scanning was more sensitive than radiographs, particularly in detecting acute sacroiliitis and hip involvement. The lumbar spine was the most frequently involved site although no part of the spine was spared. Extensive destruction of a vertebral body with little involvement of the adjacent vertebrae, lower lumbar spondylolysis and spondylolisthesis, and discitis with calcification were striking radiological findings hitherto undescribed in brucellosis. Computerized axial tomography (CAT) scanning revealed vertebral-arch destruction in three cases of spondylolisthesis. Circumferential sclerosis of the vertebral bodies was another CAT-scan finding.

A genetic marker for rheumatic heart disease.

The frequency of antigen types (A, B, C, and DR) in an unselected group of 25 patients with chronic rheumatic heart disease and an unselected group of 15 patients with acute rheumatic fever was compared with that in a group of 100 healthy volunteers. All patients and controls were Arabs of Saudi origin. Only the frequency of HLA-DR4 was significantly different in the controls and the patient groups--controls 12%, chronic rheumatic heart disease 72%, acute rheumatic fever 53%, both patient groups together 65% (relative risk 13.6 with 95% confidence interval 10.5-16.7). Eighty three per cent of 12 patients with mitral stenosis and 70% of seven with aortic incompetence had HLA-DR4 antigen. In 17 non-Saudi Arab patients who had acute rheumatic fever or chronic rheumatic heart disease, the frequency of HLA-DR4 was identical (65%) to that in Saudi patients. These findings may have implications for the pathogenesis of rheumatic fever and rheumatic heart disease.

Papillon-Lefevre syndrome. A report of six cases in one family.

Papillon-Lefevre syndrome in six Saudi children in the same family is described. The parents were unaffected, and parental consanguinity was present. Palmoplantar keratosis started at the age of 1 1/2 years. The loss of deciduous teeth was a consequence of juvenile periodontitis. All essential features of the syndrome were present in this series.

Treatment of Schistosoma mansoni infection with oxamniquine in Riyadh, Saudi Arabia.

Single dose therapy with oral oxamniquine was given to 107 Saudi patients suffering from schistosomiasis due to Schistosoma mansoni and they were followed for a period of six months. Clinical cure judged by symptomatic improvement and negative stool counts for S. mansoni eggs was achieved in 88.8%. Side effects were minimal and reversible and it is concluded that this form of treatment is successful for the control of S. mansoni infection.
