A reappraisal of routine marrow examination therapy of acute lymphoblasticv leukaemia.

Out of 557 routine marrow examinations performed in children receiving maintenance therapy, or having completed therapy, for acute lymphoblastic leukaemia or non-Hodgkin's lymphoma, only 9 marrow relapses were found. Out of 14 marrow examinations performed because of haematological or clinical indications of possible relapse, only 3 failed to confirm relapse. It is suggested that routine marrow examination to detect relapse is not worthwhile and should be stopped.

A technique to prepare asbestos air samples for light and electron microscopy.

The direct transfer technique used in preparing waterborne asbestos for analysis by transmission electron microscopy is also suitable for preparing airborne asbestos collected on polycarbonate filters for light microscopy, scanning, and transmission electron microscopy. The same area and even the same fibre may be examined by the three microscopic methods and individual fibres identified by optical and electron-optical techniques and by x-ray microanalysis.

Bilateral anteromedial defect of the diaphragm in children.

Four cases are reported, along with a review of the literature, to demonstrate the radiographic and clinial spectrum of bilateral anteromedial defect of the diaphragm in infants and children. Bilateral anteromedial defect of the diaphragm produces a characteristic radiographic pattern on herniation of abdominal structures through a single midline opening. The usually solid herniated structures elevate the heart and thymus producing a three-tiered snowman appearance. The lateral chest view substantiates the anterior location differentiating anteromedial herniation from eventration, partial or complete. Diagnosis can be confirmed by pneumoperitoneography but the high incidence of liver herniation allows less invasive determination by radionuclide scanning. While many patients will be asymptomatic, clinical symptoms can be severe due to pulmonary compression and hypoplasia or associated cardiovascular abnormalities.

The distribution of amylobarbitone, butobarbitone, pentobarbitone and quinalbarbitone and the hydroxylated metabolites in man.

Fluid and tissue specimens collected from 30 subjects at autopsy have been assayed for their content of common sedative barbiturates and the corresponding hydroxylated metabolites by g.l.c. Where one barbiturate had been ingested an inverse relationship between lipid solubility of the drug and the distribution in fluids and tissues was observed. In most cases the liver, and in the remainder the spleen, contained the highest concentrations of barbiturate. Bile concentrations were often in excess of those in the corresponding liver. The metabolites of the four sedative barbiturates were usually present in lower amounts than the parent drugs in the fluids and tissues of most subjects but urine often contained much higher concentrations of metabolites--sometimes exceeding that of the parent drug in the liver. Administration of two or more barbiturates together did not appear to affect the distribution and metabolism of the individual drugs.

Cholecystitis and hydrops of the gallbladder in the newborn.

Inflammatory gallbladder disease is not usually considered in the evaluation of septic newborn infants. When present, the radiographic findings are thought to be sparse. Three instances were recently encountered with radiographic evidence to indicate right upper quadrant abdominal disease. In one, a negative defect on the bodygram phase film of a high volume contrast study demonstrated gallbladder hydrops. Cholecystitis extended to obstruct the pyloroduodenal area with inflammatory reaction in 2 other patients. In all instances, the radiographic changes prompted surgical intervention at an early age.

Atypical radiographic appearance and clinical presentation of pulmonary tuberculosis.

Fourteen patients with unusual presentation of pulmonary tuberculosis are described. Often, exposure to the tubercle bacillus was not apparent. In other cases, there was tuberculous infection or reactivation of a previous focus in individuals with altered immunity. The radiographic presentation often differed from the classic cavitating upper lobe disease. Persistent pneumonia, cavities, and nodules were seen in other areas of the lung including the anterior segments and the lung bases. Isolated effusion and solitary nodules were also evident. Increased suspicion of tuberculosis should be maintained when evaluating persistent parenchymal consolidation, effusion, and cavitating pulmonary disease.

Reduced severity of Rh-haemolytic disease after anti-D immunoglobulin.

A total of 2459 Rh-negative women who received anti-D immunoglobulin after a Rh-positive pregnancy were followed up in at least one subsequent pregnancy. There was a failure of protection rate of 1-6%. Follow-up of 53 subsequent infants of mother in whom protection had failed showed that the infants were less severely affected than would have been expected. This was confirmed by a comparative statistical analysis of the present series and a series of first affected cases before anti-D immunoglobulin was available, using the antibody titre during pregnancy and the haemoglobin levels at delivery.

Experimental Closure of Arteriovenous Fistula by Transcatheter Electrocoagulation.

Introduction of a small electric current by way of a catheter-placed electrode can completely occlude experimentally produced arteriovenous fistula. The occlusion appears permanent and without morbidity in experimental animals. This technique might be clinically useful in obliterating an arteriovenous fistula and controlling gastrointestinal hemorrhage.
