        Choanal atresia is uncommon and consists of congenital blockage between the nasal cavity and the nasopharynx. The anomaly presents either immediately after birth as respiratory distress, or as a coincidental finding at an older age. Treatment is usually surgical. The approaches are transnasal, transseptal, transpalatal and transantral. Different types of stents are used and for various periods after each type of correction. Between 1983-1996, 20 patients with choanal atresia were operated on, in 12 of whom it was bilateral. The youngest was 3 days old and the oldest 22 years (average 6 years). The 20 patients underwent a total of 29 operations of which all were transnasal except for 2 corrected through a transseptal approach; 3 had their primary operation elsewhere. In all cases the atresia was bony or combined bony and membranous, except for 2 in whom there was combined atresia on 1 side and membranous on the other. The success rate was 75% in those first operated on here, in whom stents were employed. In our last 5 cases we used the endonasal approach and a rigid endoscope, a safe technique that has the advantage of direct unobscured vision.

        Erythromycin is considered the drug of choice in the treatment of streptococcal pharyngitis in patients allergic to penicillin. However, in recent years several publications, especially in Finland and Italy, showed high resistance rates of S. pyogenes isolates to erythromycin and other new macrolides. To evaluate the situation in Israel, we checked the MIC of isolates from patients with tonsillitis during 1996. E-test results showed an MIC-50 of 0.23, 0.13 and 0.47 mcg/ml for erythromycin, clarithromycin and roxithromycin, respectively and a MIC-90 of 0.37, 0.23 and 0.78 mcg/ml. Only 2 isolates (2.1%) were partially or completely resistant to all 3 antibiotics. We conclude that empiric therapy with macrolides in Israel is still a viable option and can be recommended in S. pyogenes tonsillitis for patients allergic to penicillin.

        The common structural and functional brain imaging techniques are described from a practical, clinical point of view. The clinical indications for brain imaging in psychiatry are reviewed in relation to the specific limitations and advantages of each technique. The clinical applications of computerized tomography (CT), magnetic resonance imaging (MRI) and single photon emission computerized tomography (SPECT) are discussed in relation to the differential diagnosis between organic and functional psychiatric disorders. In a 55-year-old man with late onset of behavioral changes but without neurological signs the application of structural brain imaging (CT and MRI) in case management was demonstrated. The imaging findings involved the differential diagnosis between depression and focal brain lesions. In a 38-year-old man with personality changes and depression following a traumatic brain injury, time interval repeated functional brain imaging (SPECT) was used. Brain imaging reflected improvement in clinical status following treatment and was able to differentiate between reversible and permanent traumatic brain injuries. The superior yield of time interval repeated functional imaging in diagnosis and management of postconcussion syndrome is discussed.

        Should Physical Restraints be used in an Acute Geriatric Ward?

        A prospective study was carried out in an acute geriatric ward to determine the incidence of the use of physical restraints, the reasons for using them and the consequences. Over a period of 8 months an independent observer documented all cases in which a restraint was used and followed them until it was removed. A questionnaire was submitted to the nurses as to why they applied the restraints. 16% of patients had some form of restraint applied, in 2/3 of them for up to half of their stay in the ward. In over 90% of those restrained, functional (Barthel) and cognitive (mini-mental) scores were between 0-5. In unrestrained patients, the functional score was 0-5 in 79% and the cognitive score 0-5 in 72%. The main reason for applying restraints, usually sheets or body binders, was to prevent the patient from falling out of, or slipping from chairs, rather than to stop them from rising out of them. Other important reasons, which overlapped, were to prevent the patient from interfering with nasogastric tubes, catheters, and IV cannulas, each in 1/3 of the group. Restraints were discarded when deterioration did not allow the patient to sit out of bed, to decrease agitation, to allow enteral or parenteral treatment, and in 12%, when there was supervision by the family. Of 33 families interviewed, none opposed application of restraints, and most left the decision to the responsible ward staff. We conclude that restraints cannot be avoided in some acutely ill, old patients with severe physical and mental dysfunction. However, ways should be sought to minimize their use, as recommended in the literature, by demanding from the staff a specific reason, signed agreement of a physician, close follow-up, and favorable environmental conditions such as suitable chairs, occupational activity, and staff cooperation in removing the restraints.

        The phenotype of susceptibility to malignant hyperthermia (MHS); can only be detected reliably by the in vitro caffeine-halothane contracture test (CHCT). Enhanced sensitivity of the calcium-induced calcium release mechanism is responsible for the exaggerated contracture response of skeletal muscle fibers from MHS patients to halothane and caffeine. Chlorocresol was demonstrated to be a potent activator of Ca++release from skeletal muscle sarcoplasmic reticulum. This effect is probably mediated through action on a ryanodine sensitive Ca++ release channel known to be more sensitive in MH. We studied the effect of chloroscresol on the mechanical contracture response of skeletal muscle from patients presenting for the in vitro CHCT. Chlorocresol induces contracture response in a concentration 1/200 of that of caffeine in muscle strips from MH patients. By adding chlorocresol to the protocol of the CHCT, there is clearer discrimination between the responses of MH patients and normal subjects can be achieved.

        Na+/H+ exchange (NHE) was measured as maximal initial velocity of pH-dependent H+ efflux from red cells into an alkaline medium containing Na+ in patients with insulin-dependent or noninsulin-dependent diabetes, with and without hypertension and in normoglycemic, essential hypertensives and normal controls (50 subjects in each subgroup). Maximal velocities of NHE were found in microalbuminuric patients in all subgroups, and NHE correlated with the rate of microalbuminuria (r=0.61, p=0.02). Daily insulin requirements were greater in those with elevated NHE (84±8 vs 42±4 U/day). There was no correlation between NHE and levels of plasma glucose, HbA1 and plasma aldosterone and lipid profile and PRA. NHE was correlated with plasma prolactin (r=0.51, p=0.02) and PTH r=0.24, p=0.05). In uremic patients, NHE was inversively correlated with creatinine clearance (r=-0.48, p=0.03). Since calphostin C, a selective inhibitor of protein kinase C, lowered increased NHE in vitro, the protein kinase C-dependent pathway of the exchanger regulation was concluded to be responsible for NHE activation in diabetes mellitus and essential hypertension.

        Depts. of Urology and Radiology, Hadassah Medical Center, Hebrew University of Jerusalem

         

        Superficial venous thrombosis of the chest wall was first described by Mondor in 1939. Braun-Falco reported in 1955 superficial penile vein involvement in diffuse thrombophlebitis of the abdominal wall and in 1958 Helm and Hodge first described isolated superficial dorsal penile vein thrombosis. Since then, fewer than 50 cases have been reported. The clinical presentation is usually redness and swelling of the dorsum of the penis, accompanied by a palpable, tender thrombotic vein. This acute and painful disease frightens the patient, who is concerned about his fertility and sexual function. The main cause of this disease is frequent sexual intercourse. Diagnosis is based upon anamnesis, physical examination and penile sonography with color Doppler imaging. It is usually a benign disease which resolves quickly under appropriate medical therapy. We present a man who was admitted for this condition and was successfully treated.

        We report a 59-year-old woman with acute fungal endocarditis of a prosthetic valve caused by the endogenic organism, Trichosporon beigelli. This slowly developing disease mainly effects drug addicts who use intravenous narcotics. In nonaddicts it is rare, with mortality as high as 50%. There are only sporadic reports of T. beigelli as a complication long after open heart surgery. The ongoing infection is undetected for even several years after the primary infection, due to its prolonged latent phase. We present the difficulties of diagnosis, and of treating the disease with a combination of surgery and of long-term chemotherapy.

        All reported case-studies in which the author-described route of infection was deemed to be casual household contact were reviewed and analyzed, as well as all sample-based studies designed to estimate the frequency of casual household transmission. Several recurring biased mechanisms of interpretation were found in the studies, the use of which made it impossible to obtain evidence for casual household transmission. After correcting for these interpretations 8 documented cases of casual household transmission were found. Analysis of the sample-based studies indicated 10 cases of casual household transmission, which occurs at a risk of 0.4% per year of contact (95% confidence interval: 0.20 to 0.66).
