Glenoid Fossa Fracture

M. Kligman, M. Roffman

Dept. of Orthopedic Surgery, Carmel Medical Center, Haifa

4 patients with displaced intra-articular glenoid fossa were treated either surgically or conservatively. After an average follow-up of 7 years, the clinical and radiographic results were satisfactory in all. The 2 treated surgically required shorter follow-up than those treated conservatively. Conservative treatment should be considered a good option for displaced intra-articular glenoid fossa fracture.

Use of Student Feedback by Pre-Clinical and Clinical Course Directors

Ruth Abramowitz, Netta Notzer

Medical Education Unit, Sackler Faculty of Medicine, Tel Aviv University

We examined the conceptual and instrumental uses of student feedback on teaching by 2 preclinical and clinical course directors with authority to change structure and content of the courses, assess suitability of instructors and to change methods of student feedback questionnaires have been collected systematically for over 2 decades. A report based on this feedback is sent to course directors, the dean, his assistants and the head of the curriculum committee. Course directors from both groups made broad use of the feedback but made greater use of the report than preclinical course directors. Students had greater regard for individual teaching by clinical course directors than by preclinical course coordinators. No relationship was found between the degree of use of feedback by members of either group and their level of teaching. We conclude that senior faculty use student feedback in their decisions regarding the structure and teaching methods of their courses and are not influenced by individual assessments, positive or negative, by their students.

CT-guided core needle biopsy of abdominal, pelvic and retroperitoneal masses is accurate and safe and can be performed on an outpatient basis. Between 1987 and 1995, 809 patients (age range 1-87 years) underwent 851 biopsies (minimal lesion diameter 1 cm). Cutting needles were always used, facilitating both cytological and histological diagnosis while minimizing risk of complications. A positive result (malignant, inflammatory or infectious) was obtained in 69% of the 809 and a negative result (normal tissue) in 17.4%, while in 13.6%, material for diagnosis was insufficient. Biopsy was repeated in 42 of them in whom radiological or clinical suspicion of malignancy was high. In 24 (60%) a positive result was obtained after the second biopsy.

Significant complications occurred in 7 (0.8%). 1 hemo-rrhaged following liver biopsy and required blood transfusion. Pancreatitis occurred in 6 (2.6%) following pancreatic biopsy. An intra-abdominal fluid collection in 1 necessitated percutaneous drainage. There was no mortality following the procedure and no documented case of needle-tract seeding of tumor. All outpatients were discharged within 3 hours of completion of the biopsy, without ill effects.

The gonadotropin-releasing hormone (GnRH) test was performed on 182 patients with various degrees of varicocele before and after low, inguinal, spermatic vein ligation, and on 18 controls. The levels of follicle-stimulating hormone (FSH) and luteinizing hormone, a synthetic GnRH (LH), were evaluated before and 45 minutes after intravenous injection of 100 mcg relisorm L. FSH levels increased more than 2-fold in 118 patients [64.8%] and LH levels increased more than 5-fold in 135 patients [74.1%]). In the control group the increase was less in all cases. Therefor, whenever FSH increased more than 2-fold and LH more than 5-fold, we considered the test positive (pathologic); On this basis the GnRH test was positive in 126 (69.2%) and negative (normal) in 56 (30.7%). Of the 126 with positive tests, only 32 (27.3%) still had a positive result 5-6 months after operation. There was correlation between a positive GnRH test and significant improvement in sperm parameters after varicocelectomy: of the 126 with positive tests before operation, sperm parameters improved in 87 patients (69%), while in the 56 patients with negative tests before operation, in only 7 (12.5%) was there improvement after correction. We conclude that a positive GnRH test indicates impairment of the hypothalamic-pituitary-gonadal axis caused by varicocele and could serve as a marker for surgical intervention with good prediction of outcome.

Prognostic Factors And Surgical Results In Traumatic Cataract

The visual outcome in 23 men and 2 women with traumatic cataracts was analyzed retrospectively. Their average age was 33 and they ranged from 10 to 69 years. Surgical results were either very good or very poor. Associated retinal injuries significantly decreased final visual acuity (p = 0.001). Those with initial visual acuity restricted to finger counting had better visual results than those with initial visual acuity restricted to light perception (p = 0.01) and hand motions (p = 0.02). Usually the lens was removed via the pars plana; the most common mode of optical correction was contact lenses.

Volume reduction surgery (VRS) is a new procedure based on the concept that relieving hyperinflation in emphysema improves diaphragmatic and chest wall mechanics and ventilation perfusion mismatch. We present our early experience with 16 patients who underwent VRS from August 1995 to June 1996. Patient selection was based on: PFT, CT scan, V/Q scan, ABG's and 6-min walk. After pulmonary rehabilitation, operation was by median sternotomy and bilateral lung shaving. Pulmonary function improved significantly. FEV1 increased from 0.68 ± 0.2 to 1.0 ± 0.2 L (p<0.01) and FVC increased from 1.7 ± 0.5 to 2.7 ± 0.5 L (p<0.017). Total lung capacity decreased from 129% ± 24% to 108% ± 20% (p<0.03). 6-min walk increased from 221 ± 90 to 404 ± 123 meters (p<0.001). Complications included 1 death, prolonged air leak in 7 cases and infection in 2. Quality of life improved substantially in 12 of the 16 cases; in 3 cases there was only slight improvement and in 1 the condition became worse. Volume reduction surgery is a promising surgical solution in selected patients with advanced emphysema.

Acute Effusive Constrictive Pericarditis in Influenza A

Constrictive pericarditis may complicate the course of several viral infections, mainly Coxsackie virus group B, as well as in rheumatoid disease, radiation and neoplasm. Perimyocardial involvement during influenzal infections is usually mild and does not progress to constriction or tamponade. A single case of cardiac tamponade caused by influenza A was reported in 1986. We report a case of acute effusive-constrictive pericarditis due to influenza A infection. Corticosteroids resulted in some benefit, but did not relieve constriction, which required extensive pericardiectomy.
