PPNG conjunctivitis.

The treatment regimen for penicillin sensitive gonococcal conjunctivitis in an adult normally includes parenteral penicillin, frequent ocular irrigation, and topical ophthalmic gentamicin or tetracycline ointment. However, if a conjunctivitis is caused by a beta-lactamase producing microbe such as PPNG, then different antibiotics are required: e.g., spectinomycin or cefoxitin parenterally and topical chloramphenicol. Also, whereas urethritis is frequently treated with singular injections of penicillin or spectinomycin HCI (Trobicin), cases of PPNG ocular infections require a much longer course of treatment often involving seven days of intramuscular or intravenous antibiotics.

Fear responses in patients with epilepsy.

Ictal fear was found equally with left- and right-sided temporal lobe foci, suggesting that basic components of fear may be bilaterally represented. With regard to interictal fear, patients with left-sided foci reported more fear of social and sexual situations, but not of animals and physical injury, compared with other groups. Men with foci in the right temporal lobe reported less fear than men with left-sided foci. It is conceivable that the two hemisphere contribute differently in the cognitive elaboration of fear responses. Alternatively, differential patterns of self-report of fearfulness may be secondary responses to cognitive or sensorimotor loss. Finally, the present study not only demonstrates differences between right and left temporal lobe epileptics, but also between these groups and those with and without other CNS dysfunction.

Runaway Costs in Medi-Cal-a myth.

An analysis of increases in Medi-Cal expenditures to their present level, more than $4 billion a year, shows them to be attributable largely to changes in eligibility and scope of benefits. The actual costs of providing care have risen at a relatively modest rate. If in fact costs are to be lowered from present levels, public policy makers must make important decisions concerning program changes which transcend merely altering payment and delivery methods.

Atopy and bronchial reactivity in Australian and Melanesian populations.

In order to compare the prevalence of atopy and bronchial hyperreactivity among Papua New Guinian (P.N.G.) and Australian populations, skin prick tests and methacholine bronchial challenge tests were performed. A civilian and an army population from each country were examined and those with past or present asthma, recent respiratory tract infection and chronic lung disease were excluded. No statistical difference in the prevalence of atopy was found between the four populations. In the P.N.G. population 40 and 49%, and in the Australian population 27 and 39%, were found to be atopic, without symptoms of past or present allergic disease. The house dust mites were the commonest allergens in all populations. In response to methacholine (0.3 mg), only 6% of subjects had falls in 1 sec forced expiratory volume (FEV1) of more than 12% (upper limit of normal range) and only two were in the asthmatic range. There was no correlation between the degree of bronchial hyperreactivity and atopic status; however, the degree of bronchial hyperreactivity was slightly greater in the New Guinea civilian than in the Australian civilian population. In the absence of asthma, atopic status does not appear to cause increased bronchial reactivity, suggesting that some factor other than atopy must be present for the development of bronchial hyperreactivity characteristic of asthma.

Cerebral ischemic events associated with prolapsing mitral valve.

Twelve patients who had no evidence of arteriosclerotic cerebral vascular disease, lacked hypertension or coagulation defect, and had not been receiving contraceptive therapy had recurrent transient cerebral ischemic attacks (TIAs) and partial nonprogressive strokes. All had prolapsing mitral valve proved by angiocardiography. The average age was 38 years, compared with 62 years in a larger series of patients with TIA associated with arteriosclerosis. We propose that the ischemic events are related to emboli emanating from the abnormal mitral valve with or without an associated paroxysmal cardiac arrhythmia.

The location of conduction abnormalities in human entrapment neuropathies.

Direct stimulation of 23 median, 13 ulnar and 2 peroneal nerves at the time of surgical exploration has been used to locate, and characterize the conduction abnormalities in the nerves. The most frequent location of the major conduction abnormalities in the median nerve was in the first 1-2 cm distal to the origin of the carpal tunnel. In the ulnar nerve the important conduction abnormalities were located most frequently in the segments 1 cm proximal and distal to the medial epicondyle. In the peroneal nerve the major conduction abnormalities occurred proximal or distal to the entry point of the common peroneal nerve into the peroneus longus muscle.

Vertebrobasilar artery insufficiency in rheumatoid atlantoaxial subluxation.

Cervical myelopathy has become commonly recognized as a complication of rheumatoid atlantoaxial subluxation. A small group of patients with atlantoaxial subluxation may have intermittent symptoms associated with change of head position and which are due to vertebral artery compression. Two such cases are reported, one with necropsy findings of infarction in the area supplied by the vertebrobasilar system. The pathogenesis of the symptomatology and infarction is discussed.

Another look at the medical "generation gap".

A 1969 survey of attitudes held by medical students and recent graduates was repeated in 1972, using the same samples of respondents and adding a new freshman group. Findings from both surveys showed that a "generation gap" existed on many issues.Furthermore, a comparison of the two studies suggested that two kinds of attitude change are occurring simultaneously. On some issues, the next generation of physicians will probably continue to differ from their predecessors. Perhaps the primary thread woven through this cluster of attitudes is that today's medical students and young physicians perceive themselves as members of a larger structure for providing health care.However, many of the students' attitudes held early in their medical careers appear to have been modified in the process of becoming physicians. It appears that medical education continues to convey many traditional professional values to students, and it seems likely that tomorrow's physicians will retain a core of those values.
