        In order to examine the effect of reflux therapy on Hyper Reactive Airway Disease (HRAD) and apnea severity, 107 children, 78 with HRAD and 29 with apnea, underwent pH monitoring in the Pediatric Surgery Unit of Wolfson Hospital and the Dana Children's Hospital during the years 1995-1998. Pathological reflux was defined by means of the Boix-Ochoa and RI (Reflux Index) scores. In patients with positive reflux, anti-reflux treatment was initiated. Prior to and following pH monitoring, the respiratory status of all patients (both with and without reflux) was evaluated by a pediatric pulmonologist employing commonly used scores to determine severity.

        Results: Subject age ranged between one day and 15 years (mean: 15.44±29 months, median: 6.37 months). In HRAD, following anti-reflex treatment the reflux positive group showed a significant score improvement, from an average of 2.9±1.1 units to 1.54±1.2 units (p<0.0001); a decrease in the number of patients treated with oral corticosteroids (p<0.01); a close to significant decrease (p=0.069) in the average dose of inhaled corticosteroids; and a decrease in the number of patients using bronchodilators (p=0.042). The reflux-negative group, not treated for reflux, displayed no significant improvement, with only a decrease in the severity scores from 2.44±1.0 to 1.78±1.2 units (p=0.14), and no change on any of the other parameters.

        In apnea, all patients improved, from an average score of 2.34±0.77 to 0.03±0.19 units (p<0.0001), with no significant difference between the reflux positive and the reflux negative groups.

        In view of these findings, it is postulated that anti-reflux therapy may have an additive effect on HRAD severity, beyond that of spontaneous respiratory improvement. We therefore find it appropriate for every severe HRAD patient (frequent exacerbations or high corticosteroid dose) to undergo pH monitoring in order to treat those with proven reflux. In respect to apnea, we cannot attribute any significance to the existence of reflux or to anti-reflux treatment.

        We conducted a retrospective 5-year survey of corneal infections treated in the ophthalmology ward of Hasharon Hospital. The most frequent type of corneal infection was corneal abscess; the most frequent cause was Staphylococcus albus, although this bacterium is not reported as a frequent cause of corneal infections.

        There was improvement in visual acuity in 69.2% and no change in 15.4%. Corneal infection by Pseudomonas aeruginosa was the most frequent cause of worsening of corneal acuity (23.08%). The greatest improvement of visual acuity was in those with corneal ulcers. The worst visual acuity was in those with corneal abscesses. Pseudomonas aeruginosa was the main cause of infection in contact-lens wearers.

        In the world medical literature, Staphylococcus albus is considered of very low virulence. This bacterium was the most frequent cause of corneal infections in our study so it may have greater virulence in Israel.

        Several studies have documented the impact of clinical pharmacy services on patient care and drug costs in hospital wards. However most hospitals in Israel do not provide such services and until recently their benefits in local health care have not been demonstrated. We therefor determined whether the activity of a pharmacist in the medical department of a medical center leads to improved quality of drug utilization and reduced costs.

         

        During the first 3 months of the clinical pharmacist's work all interventions and consultation were documented. The effect of these interventions on drug costs was calculated by the change in drug acquisition costs during the study period compared with those of preceding months, as well as in the other 5 medical departments of the hospital without clinical pharmacy services.

         

        During the study period the pharmacist joined 44 clinical rounds in which he documented 40 consultations in response to physicians' requests for drug information and 42 interventions on his own initiative. The pharmacist's recommendations were accepted in 38 of the 42 cases (90%). In 10 cases the pharmacist's initiative in improving the quality of drug therapy led to an increase in drug acquisition costs. However, the overall drug costs during the study period decreased 12.6%. During the same period drug costs in the other medical departments decreased only 2.2%.

         

        The results of this study conform with those of many other studies that show a beneficial impact of the clinical pharmacist on the quality of drug therapy and on drug costs. They indicate that the clinical pharmacist can play a crucial role in the medical department.

        It has been shown that the inspiratory muscles of patients with congestive heart failure (CHF) are weaker than normal. This weakness may contribute to dyspnea and limit exercise capacity. But respiratory muscles can be trained for increase in both strength and endurance. This study was designed to evaluate the effect of specific inspiratory muscle training (SIMT) on muscular performance, lung function, dyspnea and exercise capacity in moderate heart failure.

        10 patients with CHF (NYHA functional class II-III) received 1/2 hour of SIMT daily, 6 times/week, for 3 months. They started breathing at a resistance 15% of their Pimax for 1 week and the resistance was then increased incrementally to 60%. Spirometry, inspiratory muscle strength and endurance, and the 12-minute walk test were performed before and after the training period. All showed an increase in inspiratory muscle strength and endurance. This was associated with a small but significant increase in FVC, a significant increase in the distance walked (458±29 to 562±32 m, p<0.01), and improvement in the dyspnea index score.

        SIMT resulted in increased inspiratory muscle strength and endurance. This increase was associated with decreased dyspnea and an increase in submaximal exercise capacity. SIMT may prove to be useful complementary therapy in CHF.

        Cardiology Dept., Bnei-Zion Medical Center and Technion Faculty of Medicine, Haifa

         

        This study was designed to assess possible diurnal fluctuations in the efficacy of thrombolysis with streptokinase. 156 consecutive patients treated with streptokinase during the period 1.1.95-1.7.96 were studied retrospectively. Success or failure of thrombolysis was determined according to the accepted clinical and angiographic criteria starting at midnight, 12 times at 2-hour intervals, then 8 times at 3-hour intervals, and then 6 times at 4-hour intervals. A definite peak for successful thrombolysis was found in the late afternoon and early evening hours. Between 16:00-20:00 PM, in 30.23% successful thrombolysis were observed, compared to 6.98% between 20:00-24:00 PM (p<0.05) and in 10.53% between 00.00-04:00 AM (p<0.05).

         

        Multiple regression analysis showed that the independent factor with the greatest impact on successful reperfusion was the actual time until thrombolysis (p=0.037); then came the interval from pain onset to streptokinase administration (p=0.020), while age and gender had much lesser impacts (p=0.328 and 0.215, respectively), and individual risk factors even less.

        These findings may have several clinical implications: dose adjustment for the time of day may be required, with larger doses needed during morning hours, or preference for primary coronary angioplasty to avoid increase in bleeding complications due to higher doses of thrombolytic agents.

        In a joint effort of the Israel Center for Disease Control, the National Center for Influenza in the Central Virology Laboratory, together with a group of collaborating pediatricians and family physicians, a network for influenza surveillance was established in the winter of 1996-97. Nose and throat swabs were obtained from 571 patients with flu-like illness. 133 (23%) were positive for influenza virus. Both influenza A(H3N2) and B were isolated, predominantly influenza B during the beginning of the season. Both circulating strains were antigenically similar to those included in the vaccine for 1996-1997. Patients from whom influenza virus was isolated were significantly more likely to suffer from cough and myalgia in comparison with patients whose cultures were negative (p=0.02 and 0.003. respectively). Results of the first year of surveillance indicate that sentinel reporting clinics are useful for timely detection and identification of the viral strains circulating in the community, thus allowing prompt intervention in preventing the spread of influenza. Conclusions from the first year of the study were drawn and applied in the winter of 1997-1998.

        Influence of Warning Labels on Medicines and Physicians' Orders on Patient Behavior

        Child Health Center of Kupat Holim Klalit, Kiryat Gat and Dept. of Family Medicine, Ben-Gurion University of the Negev, Beer Sheba

         

        Compliance of 40 mothers with a warning label, "for external use," on a medicine package was checked in a survey in a primary care clinic for children. We also checked parents' attitudes to giving a medicine to their child when instructions given by the physician or by a friend contradicted the printed warning on the label. All mothers who were told that the medicine was recommended by their physicians accepted the recommendation without hesitation. Another group included 20 mothers who were told that the medicine was recommended by a friend. 9 of 20 mothers in this group refused to use the medicine. Talking with the nurse about the potential risk of medicine in general, some mothers, after second thought, refused to give the medicine to their child. At the end, 65% of recommendations made by a friend were rejected by mothers as compared to only 15% of the physicians' recommendations.

         

        35 of 40 mothers (87%) understood the meaning of the warning label, but only 13 (32%) had noticed it at all. We conclude that patients may accept their physicians' recommendation to use a medicine despite a contradictory warning label much more readily than when it was recommended by a friend. Therefore, any intervention program intended to promote a more cautious use of medicines should include not only the explanations of the various warning labels but should also promote a change in the patient's behavior to a more active search for warning labels.

        In the past 10 years there has been a growing preference for early, complete correction of congenital heart disease. The first year of operation of this cardiac unit is described. 216 operations were performed: 15% in the neonatal age group and 35% in the newborn to l-year-old groups; 2% were palliative procedures. Mortality was 4.9%. Average stay in the ICU was 3.2  days, with a median of 2.25. Average length of ventilation was 35 hours, with a median of 17.5. Complications were: diaphragm paralysis in 13 (6%), 2/3 of which were recurrent operations; in 2 patients (0.9%) we had to plicate the diaphragm. There was severe neurological damage in 2, which deteriorated to brain death in 1. There was peripheral, reversible neurological damage in 4 (1.8%), and acute renal failure in 3%, with half of them requiring dialysis. 75% of these children died and there was superficial infection in 4.1%, deep wound infection in 1.3%, bacteremia in 4.1%, superior vena cava syndrome in 3 (1.3%) and chylothorax in 2 of them (0.9%). 1 patient (0.45%) required a ventricle-peritoneal shunt after acute viral meningitis. We are encouraged by our results to offer early complete correction to all children with congenital heart disease.

        Circadian Fluctuations of the Signal-Averaged ECG

        Circadian periodicity for the time of onset of acute myocardial infarction has been shown; the early morning peak of infarction coincides with the onset of other related phenomena, including sudden cardiac death, ventricular arrhythmias, thrombotic stroke, etc. Late potentials detected by the signal-averaged ECG are considered to be independent markers of vulnerability to ventricular arrhythmias. The signal-averaged ECG enables the amplifying and recording of small bioelectric signals of cardiac origin, while eliminating extraneous electrical "noise." To determine whether late potentials are themselves subject to circadian influence, 31 patients (age range 41-79) who had had an old or recent myocardial infarction underwent late potential assessment by the signal-averaged ECG. 4 indices were studied: duration of late LPD potentials (LPD), total QRS duration (TQRS), and root mean square voltage of the last 40 msec, and of the last 50 msec (RMS 40 and RMS 50). These indices were assessed 3 times, during the early morning hours, at noon and during the evening. Morning LPD differed significantly from noon and evening LPD and the morning RMS 40 similarly differed from noon and evening values. TQRS and RMS 50, even though remaining in the normal range, also showed a tendency to abnormal values during morning hours. These findings could possibly be related to the early morning incidence peaks of severe ventricular arrhythmia and sudden cardiac death, since abnormal late potentials constitute the physiopathological basis for certain ventricular arrhythmias.

        A 43-year-old man presented with weakness, pruritus, skin rash and jaundice 2 weeks after treatment for onychomycosis with terbinafine (Lamisil) was started. Liver function tests showed combined hepatocellular and cholestatic injury. Ultrasound examination, computerized tomography and ERCP excluded extrahepatic obstruction. Serology was negative for HBV, HCV, HAV, CMV, and EBV. Liver biopsy was consistent with drug-induced cholestatic injury. Since the clinical picture did not improve when terbinafine was stopped, corticosteroids were started and resulted in complete clinical and laboratory recovery; liver function tests were normal 8 months after corticosteroids were discontinued.

        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.

        Food-withdrawal has been proposed as a possible mechanism for initiating the onset of labor in animals and humans. The hypothesis was based upon the reported increase in deliveries of infants during the Yom Kippur fast. We studied the effect of the fast on full term deliveries of Jewish women, with non-fasting Bedouin women as controls (1988-1995, 1,313 Jewish and 1,091 Bedouin deliveries). To determine the effect of Yom Kippur itself, delivery rates on Sukkot and Yom Kippur were compared in both groups. The mean delivery rate in the Jewish population was significantly higher during Yom Kippur and the day after, than during the 7 days before Yom Kippur (15.1±5.1 and 14.6±4.7 vs 10.7±3.5, p<0.04 and p<0.01, respectively). There was an increase in delivery rate during the 6 hours before the end of the fast. In the Bedouin women there were no changes in delivery rate during any of these periods. There were no significant differences in the rates of deliveries during the Sukkot festival between Jewish and Bedouin women. We conclude that fasting is associated with a significant increase in the rate of deliveries at term.

        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.
