Medullary hemorrhage causing vertigo and gaze nystagmus.

Brainstem hematomas carry a poor prognosis. There are rare reports of excellent outcome with hemorrhages in the midbrain. We report a 43-year-old woman with vertigo and minimal neurological symptoms, whose symptoms were initially mistaken for "inner ear disease," but subsequent investigations revealed a medullary hemorrhage. Recovery was complete within two weeks. While rare, medullary hemorrhage should be considered in the differential diagnosis of vertigo.

Sarcoidosis in Arabs: the clinical profile of 20 patients and review of the literature.

Sarcoidosis is being increasingly recognised in Kuwait. Twenty patients were studied over three years and the clinical, biochemical and radiological data were analysed. The clinical profile revealed thoracic involvement in all the patients as well as constitutional symptoms (50%), arthralgia (55%), arthritis (15%), chest infection (35%), tuberculosis (10%), hypercalcaemia (5%), angina (15%) and hypertension (20%). None had central nervous system manifestations. Other clinical signs were erythema nodosum (25%), hepatomegaly (30%) splenomegaly (15%) and chest signs (25%), together with salivary gland (15%), skin (15%), eye (15%), and cardiac involvement (5%). The tuberculin test was negative in all those tested. The patients were classified radiologically into stage I (55%), stage II (40%) and stage III (5%) of the disease. The clinical profile was similar to the Western pattern of the disease, but there were several differences including an older age group, more frequent constitutional symptoms, the rarity of ocular and central nervous system involvement, and initial presentation as a chest infection. Therapy with steroids alone or steroids and azathioprine was used when appropriate and the response to therapy monitored.

Computed tomography manifestations of brucellosis of the sternoclavicular joint.

Computed tomography (CT) in three patients with sternoclavicular brucellosis revealed the following features: soft-tissue mass centred around the joint, sclerosis with or without lysis of the periarticular bone, and destruction and irregularity of the cortex of the sternal and clavicular articular surfaces. The CT features, in the appropriate clinical setting, should help in making the correct diagnosis and managing this serious but rare manifestation of brucellosis.

Abdominal tuberculosis in children: CT findings.

Tuberculous peritonitis is a rare manifestation of childhood tuberculosis. The computed tomographic (CT) scans of three patients with abdominal tuberculosis were reviewed to determine the range of abdominal involvement. This report describes the following CT features of abdominal tuberculosis: (1) diffuse lymphadenopathy involving mesenteric and retroperitoneal lymph nodes; (2) low-density lymph nodes with multilocular appearance following intravenous contrast; (3) high-density ascites; (4) mottled low-density masses in the omentum; (5) thickening of the bowel wall adjacent to the mesentery; and (6) hepatic pseudotumors. These CT features of abdominal tuberculosis, in the appropriate clinical setting, should help optimize the correct diagnosis and management of tuberculosis in children.

Improved immunotherapy for pulmonary tuberculosis with Mycobacterium vaccae.

We previously demonstrated that a single intradermal injection of 10(9) irradiation-killed M. vaccae, given 1 month after starting chemotherapy, caused significant changes in responses to mycobacterial antigens. Amongst 38 patients with pulmonary tuberculosis, 29% had lymphocytes responding to common myocobacterial antigens after the injection, compared with only 11% of 49 similar patients after an injection of saline (p less than 0.03). To increase the proportion of responders to these antigens, six modifications of the potentially immunotherapeutic injection, randomized with injections of saline, have been assessed by biochemical, clinical, haematological, immunological and radiological criteria. Subsequent lymphocyte proliferation to mycobacterial antigens enabled the modifications to be ranked in order of efficacy. Tuberculin plus murabutide plus 10(9) irradiated M. vaccae (36% of 25), an autoclaved preparation of 10(9) M. vaccae (45% of 22), and 2 x 10(9) irradiated M. vaccae (75% of 12) were the most effective. Antibody responses in several IgG subclasses to mycobacteria, but not streptococci, were also significantly increased by the most effective modifications over the 8 weeks following injection. Detailed radiological study showed that use of the autoclaved bacilli was followed by a delay in clearing of consolidation, but by better closing of cavities than was found in the control group, suggesting enhanced, or altered, immunological activity around the lesions.

A unique case of Munchausen's syndrome.

A most unusual case of Munchausen's syndrome in an 18-year-old Yemeni female is described. The patient presented with bleeding from various sites; repeated subcutaneous emphysema of the face, orbit and upper chest; ulcers on the tongue, and dermatitis autogenica. The illness was confirmed to be factitious and self-induced when she was caught red-handed trying to inject air. We believe this to be the first report of a case where all these features occurred concurrently and only the second report where a patient developed self-induced orbital emphysema.

Insulinoma in a black South African. A case report.

A 69-year-old black woman with an insulinoma presented with recurrent episodes of sweating and confusion culminating in two episodes of hypoglycaemic coma. The diagnosis was confirmed by finding an inappropriately elevated serum insulin level in the presence of hypoglycaemia after a fast of 14 hours. Computed tomography revealed a large tumour in the head of the pancreas. Removal of the tumour necessitated partial resection of the head and body of the pancreas, which in turn necessitated certain repair and drainage procedures. Postoperative complications, while not insignificant, were acceptable. At 1-year follow-up the patient is well.

Orbital varix--an unusual cause of proptosis. A case report.

An orbital varix is a pathological enlargement of the venous channels within the orbit. It is an unusual cause of proptosis, the proptosis being unilateral, painless and intermittent. The diagnosis is established by means of orbital venography, an investigation seldom performed.
