Fusarium endocarditis involving aortic valve following coronary artery surgery

This article describes a case of infective aortic valve endocarditisdue to Fusarium oxysporum occurring 4 years after coronary arterybypass grafting. It is the first reported case of endocarditiscaused by Fusarium.     

USE OF POST-TETANIC COUNT IN ASSESSMENT OF A REPETITIVE VECURONIUM-INDUCED NEUROMUSCULAR BLOCK

In order to evaluate the use of the post-tetanic count (PTC)method during repetitive administration of vecuronium, we studied20 patients allocated randomly to one of two groups: 10 patientsreceived droperidol-fentanyl anaesthesia (control group); 10other patients were given droperidol-fentanyl anaesthesia modifiedsubsequently by addition of 0.5% isoflurane (isoflurane group).Before tracheal intubation, a bolus dose of vecuronium 0.08mg kg^–1 was given i. v. followed by repeated doses of0.03 mg kg^–1. The twitch response of adductor polliciswas recorded after supramaximal stimulation of the ulnar nerveat the wrist using a Myograph 2000 neuromuscular transmissionanalyser. In the control group, a close correlation was foundbetween PTC and time to first reaction to train-of-four (TOF)nerve stimulation. This relationship was unchanged when comparingthe bolus dose and each of eight consecutive maintenance doses.Further, the degree and the duration of intense block were unchangedafter each of the eight maintenance doses. In the isofluranegroup, the relationship between PTC and time to first reactionto TOF stimulation remained unchanged after addition of isoflurane.However, isoflurane caused a significant prolongation of theduration of intense block and a corresponding lower PTC in allpatients. We conclude that PTC is a reliable method to evaluateintense neuromuscular block caused by vecuronium, even afterrepetitive administration of the drug and in combination with0.5% isoflurane.

Vertical Banded Gastroplasty-Gastric Bypass with and without the Interposition of Jejunum: Preliminary Report

Background: The complications of the gastric pouch in gastric bypass surgery are well known. Since the first report of this surgery 30 years ago, new technical aspects that make it safer and more effective have been implemented. Methods: As a modification of gastric bypass, the authors have performed 305 vertical banded gastroplasty-gastric bypass procedures. Two groups of patients underwent the procedure: Group I (n = 206) without a limb of jejunum interposed between the gastric pouch and the excluded stomach, and Group II (n = 99) with a limb of jejunum interposed between the pouch and the stomach. The results regarding excess weight loss and complications of the gastric pouch during the first year after surgery were compared. Results: Age, sex, initial weight, body mass index, and percentage of ideal weight were similar in both groups. Excess weight loss was also similar. The complications in Group I were 1 leak, 3 left subphrenic abscesses, 2 erosive gastritis with bleeding, 1 stenosis of the gastrojejunostomy, 1 perforated ulcer, and 4 marginal ulcers with bleeding. Two patients in Group II developed bleeding from the staple-line. Conclusions: These preliminary data suggest that complications of the gastric pouch can be reduced by interposing a limb of jejunum between the pouch and the excluded stomach. This is an early experience; long-term results are pending.     

Renal immunoblastic sarcoma complicating immunosuppressive therapy for wegener granulomatosis

A renal tumor developing in a patient receiving cyclophosphamide (Cytoxan) therapy for Wegener granulomatosis is reported. The tumor was similar histologically to the "immunoblastic" sarcoma that develops in renal allograft recipients as a complication of immunosuppressive therapy. This case report strengthens the cause and effect relationship between immunosuppressive drug usage and the subsequent development of neoplasia.     

Infants born to narcotic dependent mothers: Physical growth patterns in the first 12 months of life

Objectives: To describe the physical growth patterns of infants born to narcotic dependent mothers (INDM) over a 12 months period and, if possible, to relate the growth to drug taking patterns during pregnancy.
Methodology: The growth of a cohort of 43 INDM was measured during the first 12 months of life. Weight and length measurements were compared with percentile charts and converted to Z scores. Questionnaire data about drug taking practices, demographic variables and the neonatal period (including withdrawal scores) were obtained.
Results: Twenty-four (55.8%) of INDM had evidence of neonatal drug withdrawal requiring treatment with phenobarbitone. At birth, Z scores for weight and length indicated relative intrauterine growth retardation. By 12 months, there had been some catch up growth, but Z scores for weight and length were still below zero. Persistent weight retardation at 12 months was correlated with methadone dosage during pregnancy, but not the need for phenobarbitone therapy.
Conclusions: The growth patterns of INDM in the first 12 months of life indicated that at birth there was evidence of intrauterine growth retardation, but by 12 months the growth was little different from the rest of the community. There appears to be some influence of narcotic agents taken while pregnant on subsequent growth of INDM.     

Microtubular inclusions in normal skin of systemic lupus erythematosus patients

Biopsy specimens of clinically normal skin of 9 consecutive patients with SLE were examined ultrastructurally to determine the presence and frequency of microtubular inclusions. Ten blood vessels were examined in each specimen; every specimen contained at least two positive blood vessels, and some contained 80 to 100% positive vessels. No correlation was found between the frequency of the inclusions and either the disease duration or antinuclear factor titer. The inclusions tended to be more frequent in patients with more acute disease. The absence of inclusions in normal skin may mitigate a diagnosis of SLE.
