Methodological Issues Associated with an Audit of Stillbirth in a Family Medicine Practice in Israel

An audit of ‘deficient outcome’ involves the step-by-stepanalysis of every event preceding the occurrence of a preventablemedical outcome in order to determine exactly what went wrong.This paper describes methodological problems and related issuesassociated with a deficient outcome audit undertaken on fivestillbirths which occurred in a rural family medical practiceIsrael between 1985 and 1987. Problems included initial officialdisinterest towards the audit, and the high levels of suspicionand antagonism which it aroused in hospital staff approachedfor information. The problematic aspect of such audits needsmore attention. The importance of this type of audit for establishing the precisereasons for perinatal deaths, and thus for maintaining antenatalcare standards is discussed. In view of the small numbers ofsuch events likely to occur within any one family practice itis not only feasible but also desirable for more family doctorsto carry out such audits routinely, despite the difficultieswhich are involved.     

Myopathies of the lower extremities

The myopathies that can manifest themselves within the lower extremity are reported here and can serve as a guideline for clinicians in the early diagnosis of these disabling conditions. The classification of these disease entities based on signs and symptoms is significant if correlated with the age of the patient at the time of onset, the evolution and course, and the type of familial inheritance. This article can also aid the practitioner in assessing and planning the course of treatment for a particular patient.     

Quantitative immunocytology as a marker for indications and follow-up of recurrence prevention of superficial urinary bladder cancers

In 1985, we initiated a prospective clinical trial to evaluate the risk of recurrence for superficial bladder cancer. Up to now, 41 patients subjected to TUR have subsequently been monitored by immunocytology with a monoclonal antibody (mab 486 p) recently developed in our laboratory. Of these patients, 15 (36.6%) remained marker-negative and received no prophylactic therapy. There was only one recurrence (6.7%) in this subset of patients, whereas 10 out of 26 (38.5%) marker-positive patients have so far developed recurrent malignancies. In all cases, the conversion of immunocytological characteristics preceded visible recurrence by 2-5 months. These preliminary results indicate that immunocytology might make it possible to identify patients at low risk of recurrence more accurately than has so far been feasible with standard cytology or flow-cytometry.     

Neutropenic enterocolitis in adults with acute leukemia

Neutropenic enterocolitis has been previously described only by case reports and literature reviews. Of 499 adults with acute leukemia seen over a 23-year period (1962 to 1985), 13 cases (2.6%) of neutropenic enterocolitis have been reported. Eleven of these 13 patients were profoundly neutropenic (mean white blood cell count, 472/cu mm) and developed abdominal symptoms during either initial induction or relapse of acute leukemia. Histologic confirmation was available in ten cases, five cases after surgical resection and five cases at autopsy after nonoperative management. Three patients with isolated ileocecal inflammation without infarction at the time of surgery were successfully managed without resection. Five patients treated with surgery died four to 64 weeks postoperatively (mean survival, 21.6 weeks) of nonsurgical complications of leukemia. Three patients were still alive, one patient 42 months after right hemicolectomy and two patients five months after exploration only. All five patients managed medically died an average of 1.4 days (range, zero to four days) after the onset of abdominal pain. Survival in patients with acute leukemia who develop neutropenic enterocolitis is determined by early recognition and appropriate surgical exploration that can be expected to yield an acceptable operative mortality.     

Role of blood flow in acute gastric lesion after hepatectomy and effect of prostaglandin I2 and H2-receptor antagonist

In order to investigate the cause of gastric mucosal lesion following hepatectomy, changes of gastric, pancreatic and femoral arterial blood flow were measured in 70% hepatectomized rabbits. Following administration of 0.5 microgram/kg of GRP, gastric blood flow increased to 120% of the basal level in the controls, but reached to only 107% of the basal level in the hepatectomized rabbits. Following hemorrhage of 10% of the total blood volume seven days after hepatectomy, blood flow decreased to 55% of the basal level in the stomach, 57% in the pancreas and 76% in the femoral artery. Although pancreatic blood flow recovered to 81% of the basal level, gastric blood flow remained low, 59% of the basal level, suggesting poor recovery of gastric blood flow as compared to pancreatic blood flow. Administration of PGI2 and ranitidine in hepatectomized rabbits with hemorrhage conferred a considerable degree of recovery of gastric blood flow in the PGI2 group (from 56% to 80%) and in the ranitidine group (from 52% to 72%). Thus, disturbance of reaction and poor recovery of gastric blood flow following hemorrhage were indicated as important causes of acute gastric mucosal lesion associated with hepatectomy. Both PGI2 and ranitidine appeared to be effective for the maintenance of gastric blood flow after hepatectomy.     

Spiral coils for arterial occlusion

Roentgen endovascular occlusion with spiral emboli was used in 240 patients with different diseases. The introduction of spiral emboli into the arteries of abdominal and retroperitoneal organs was fulfilled through usual angiographic catheters. Duration of the arterial occlusion was checked up in the following angiographic examinations and showed the devices described to be appropriate for a continuous arterial blockade. No complications resulting from the introduction of the spiral embolus were noted.     

Enzyme immunoassays and related procedures in diagnostic medical virology

This review article describes several applications of the widely used enzyme immunoassay (EIA) procedure. EIA methods have been adapted to solve problems in diagnostic virology where sensitivity, specificity, or practicability is required. Concurrent developments in hybridoma and conjugation methods have increased significantly the use of these assays. A general overview of EIA methods is given together with typical examples of their use in diagnostic medical virology; attention is drawn to possible pitfalls. Recent advances in recombinant DNA technology have made it possible to produce highly specific nucleic acid probes that have a sensitivity approximately 100 times greater than that of EIA. Some applications of these probes are described. Although the non-labelled nucleic acid probes for use in the field are not as refined as non-labelled immunoassays, their range of applications is expected to expand rapidly in the near future.
