Children's drawings about dentistry.

Drawings about the dentist at work were solicited from 1,101 children in grades 2, 4, 6 and 8 in an urban school district. A system to classify the contents of these drawings was developed. The frequency of various items occurring in the children's drawings was determined. The "typical" or most frequent child's drawing of the dentist at work was described. This drawing contained a normal dental chair, dentist, a patient in the chair and dental cabinetry or furniture. The picture was a very matter-of-fact representation. Abnormal or bizarre pictures occurred infrequently. A few children drew pictures that did not relate to dentistry.

Late cardiac tamponade: a potentially lethal complication of open-heart surgery.

Cardiac tamponade occurring late after open-heart surgery is a frequently fatal complication. Of the 13 cases previously reported in the literature, there were seven deaths. In this report, three additional patients with late cardiac tamponade successfully treated are presented. Postoperative anticoagulation with Coumadin appeared to contribute to this complication. Increased awareness of late cardiac tamponade allowing prompt recognition and immediate decompression of the pericardial sac should lower the high mortality rate previously associated with the condition.

Evaluation of fecal technics for the diagnosis of cat liver fluke infection.

The comparative efficiency of 5 standard technics for the detection of feline liver fluke ova in feces was evaluated. The formalin-ether technic proved superior to direct smear, sugar flotation, zinc sulfate flotation, or detergent sedimentation technics. The formalin-ether technic correctly diagnosed all Platynosomum concinnum-infected cats studied, as confirmed by necropsy findings.

Hydrolysis of carbon-labeled cocaine in human serum.

Hydrolysis of 14C-cocaine in human serum, separation of the metabolites on TLC, and subsequent identification on GLC is described. AT 1 H, 20 percent of the cocaine was metabolized to benzoylecgonine, ecgonine and ecgonine methylester. At this time interval the highest percent of product was in the form of the ecogonine methyl ester, a metabolite not previously reported in humans. After 4 h, 67 percent of the cocaine was hydrolyzed; of this, 45 percent was benzoylecgonine and ecgonine in a ratio of 1.6 to 1. The half-life for cocaine hydrolyzed in human serum was approximately 2.5 h.

Factors influencing survival following postinfarction ventricular septal defects.

Postinfarction ventricular septal defect (VSD) carries a grave prognosis. Surgical closure appears to improve survival. Eighteen patients with postinfarction VSD are reviewed. Nine died before operation could be performed and 9 underwent closure of the VSD; 4 patients are late survivors. Factors which appear to influence survival are: (1) time of surgical intervention after appearance of VSD, (2) presence or absence of cardiogenic shock, (3) location of the infarct, and (4) operative approach to the VSD. Based on these factors, a method of management for postinfarction VSD is outlined.

Burkitt's lymphoma presenting as acute leukaemia.

A Nigerian male child presented with extensive superficial lymphadenopathy, a bleeding diathesis, and numerous tumour cells in blood and bone marrow. Further characterization of the tumour cells confirmed the diagnosis of Burkitt's lymphoma. The main unusual features shown by this patient are discussed.

Differentiating feline T and B lymphocytes by rosette formation.

The number of bone marrow-derived and thymus-dependent lymphocytes in the peripheral blood of felines was assessed. Feline bone marrow-derived lymphocytes were determined by erythrocyte antibody complement (EAC)-rosette formation and membrane immunofluorescence. A good correlation was observed between the cells forming EAC-rosettes (mean of 40.2 +/- 9.7%) and those possessing membrane immunoglobulins (mean of 45.3 +/- 4.1%). Feline thymus-dependent lymphocytes form non-immune (E)-rosettes with rodent erythrocytes (mouse, rat, guinea pig) but not with erythrocytes from humans, monkeys, dogs, mongooses, chickens, rabbits, sheep, and hamsters. An average of 32.3 +/- 992% of the peripheral blood lymphobytes of cats formed rosettes with guinea pig erythrocytes. Antibody blocking, cytotoxicity, and mix-rosette studies demonstrated that guinea pig red blood cells bind specifically to T lymphocytes. Of feline peripheral blood lymphocytes, 41.0 +/- 7.5% showed fluorescent staining with fluorescein-labeled rabbit anti-cat thymus antiserum.
