Bilateral pneumothorax following tracheal intubation.
An elderly patient undergoing elective cholecystectomy, developed bilateral pneumothorax following intubation of the trachea and manual ventilation of the lungs. Diagnosis was confirmed by chest x-ray and drainage with wide bore cannulae. Drainage of the chest was necessary.
Post-yersinial arthritis in Cleveland, England.
Four cases of post-yersinial reactive arthritis are described. All patients presented with an acute lower limb arthropathy with features of an associated enthesopathy. Two patients had restriction of axial skeletal movements. Systemic features were prominent in three, including weight loss and malaise. Mean age of onset was 34 years. Three patients gave a history of antecedent diarrhoea within the previous month. Three patients had raised titres to Y enterocolitica type 0:3 (ranging from 1 in 320 to 1 in 2560) and one had raised titres to Y pseudotuberculosis type 2 at 1 in 640. Two of the three patients with Y enterocolitica reactive arthritis ran a chronic course with low grade arthropathy of lower limbs and back stiffness. One patient developed radiological sacroiliitis at two years, and two patients had an increased sacroiliac index, though x rays of the sacroiliac joints were normal. The patient with Y pseudotuberculosis reactive arthritis had a self limiting disease with spontaneous resolution over six months.
Recurrent pyogenic meningitis--a retrospective study.
Records of 17 patients who had two or more attacks of pyogenic meningitis were collected from eight centres in the United Kingdom for retrospective analysis. Thirteen patients had intracranial abnormality; of seven with head injury five produced cerebrospinal fluid rhinorrhoea. The first of the 28 attacks seen in these occurred between a few weeks and 12 years of the head injury. Pneumococci were identified in 25 episodes in cerebrospinal fluid. Of six patients without a history of head injury, one had 'spontaneous cerebrospinal fluid rhinorrhoea' and five had pathological changes of the ear. Various organisms were found in the cerebrospinal fluid during the 12 attacks in these five. Four of the 17 patients had primary complement deficiency (C7, C5, C4 and C3b inhibitor); 10 (possibly 11) of 16 attacks in these cases were due to Neisseria meningitidis. Routine radiological investigations including computerized tomography did not always identify the abnormality; radioactive cisternography can help to establish cerebrospinal fluid leak. All 58 episodes of pyogenic meningitis in these 17 patients with different underlying disease responded to conventional treatment with antibiotics without mortality and without undue morbidity. Surgical procedures in intracranial disease had variable success. Correction of complement deficiency is not practical at present. In some patients prophylaxis with antimicrobial drugs is the only method of preventing future attacks.
Embryopathic effects of ethanol in the chick.
The chick embryo is considered a highly sensitive system for the screening of drugs for possible teratogenicity. The effects of varying concentrations of ethanol on the early development of chick embryos were studied. The mean weight of embryos exposed to ethanol was reduced compared to that of the control groups, but the difference was not significant. However, embryolethality and the incidence of abnormal embryos were significantly increased and related to the dose of ethanol.
