Occupational lead exposure and renin release.

Hypertension may result from chronic lead exposure. Lead poisoning arising from "moonshine whiskey" drinking has been associated with a rise in plasma renin activity. In the present study, plasma renin concentration following intravenous administration of frusemide was measured in eleven subjects with moderate or severe lead poisoning of industrial origin. The results were compared with those obtained for seven normal, control subjects. There was no significant difference in response obtained in the two groups. Industrial lead poisoning does not appear to affect renin release. The combined insult of lead and alcohol may explain the findings in the previous study.

The inferior turbinate mast cell population of patients with perennial allergic and nonallergic rhinitis.

The number of mast cells in the inferior turbinates of patients with perennial allergic rhinitis and perennial nonallergic rhinitis was compared with normal controls. Mast cell counts expressed as the mean number in 100 high-power fields, assessed after Carnoy's fixation and toluidine blue staining were 1.84 in normal controls (n = 11), 4.39 in patients with perennial allergic rhinitis (n = 13), and 4.00 in those with perennial nonallergic rhinitis (n = 26). Statistical analysis confirmed that the density of mast cells in allergic as well as in nonallergic patients was significantly higher than in normal controls, whereas no significant difference was found between the number of mast cells in allergic and nonallergic patients. It is concluded that the number of mast cells in the inferior turbinate mucosa of patients with perennial rhinitis is increased compared with normal controls, and the increased number is not necessarily allergy-dependent.

The accuracy of diagnostic laparoscopy in trauma patients: a prospective, controlled study.

BACKGROUND: Numerous studies advocate the use of diagnostic laparoscopy (DL) for abdominal trauma, but none have documented its ability to diagnose specific injuries. This study tests the hypothesis that DL can accurately identify all significant intra-abdominal injuries in trauma patients. METHODS: Of trauma patients requiring laparotomy for presumed injuries, 47 underwent DL followed by laparotomy. Injuries noted at laparoscopy were compared with those found at laparotomy. RESULTS: Of these, 14 patients had no significant injuries necessitating operative intervention noted at laparoscopy and celiotomy. The remaining 33 patients harbored 93 significant injuries at laparotomy, of which only 57.0% were found by DL. DL possessed poor sensitivity (<50%) for injuries to hollow viscera. Despite DL's poor performance in finding specific injuries, it possessed excellent sensitivity (96.2%), and specificity (100%) for determining the need for therapeutic celiotomy. CONCLUSIONS: DL offers no clear advantage over diagnostic peritoneal lavage and computed tomography in blunt trauma. Its utility lies in assessment of the need for laparotomy in patients with penetrating wounds. Currently, DL cannot consistently identify all abdominal injuries, disqualifying it as a therapeutic tool in abdominal trauma.

A prospective study of the neurological effects of lead in children.

In the past three years, our research group has investigated the relationship between lead exposure and mental and behavioural development. This has been carried out through studies in children and studies in animals. Earlier studies in children have shown that associations might be expected between environmental exposure to lead and various aspects of cognitive and behavioural development. Our study has examined, and continues to examine, a cohort of 151 children subdivided into three groups according to the level of lead exposure during early in utero development as assessed by maternal blood lead concentration and water lead exposure in early pregnancy. Data amassed to date include measurement of psychometric function and postnatal development at the ages of 1 and 2, together with biochemical measures of lead exposure. Assessment will continue through to early scholastic performance and will include measurement of deciduous tooth lead concentration as an integrated measure of long-term exposure.

Self psychology and the distinctiveness of psychotherapy.

After a brief review of some major theoretical points of the psychology of the self, psychotherapy is delineated from psychoanalysis via this perspective. The suggestion is made that the difference lies less in the method than in the goal. Clinical examples illustrate that the goal of psychotherapy consists of a repair of the self. This is in contrast to the goal of psychoanalysis which is a reorganization of the self An accurate diagnostic assessment of the nature of the individual psychopathology enables one to recommend either reparative (that is, psychotherapeutic in the narrow sense) or reconstructive (psychoanalytic) treatment.
