During the winter of 1995, nasopharyngeal colonization of Streptococcus pneumoniae was evaluated in 204 children with respiratory infection and 107 normal control children. There was no difference in gender or mean age between the groups, and no difference in carrier rate between sick (24.5%) and normal (22%) children (p=0.6). Carrier rates were 19%, 32%, 31% and 17% at 6, 12, 24 and 48 months, respectively. Penicillin-resistant pneumococci (PRP) were found in 42% of sick and 16.6% of normal children, (p<0.05). Resistance to more than 2 antibiotics was found in 28% of sick and in 12.5% of normal children. PRP were found in 67% and 34% of sick children with and without prior antibiotic treatment (p<0.05). We conclude that there is no difference in the carrier rate of Streptococcus pneumoniae between sick and normal children. However, the high prevalence of PRP in children with respiratory infections is probably due to prior antibiotic treatment.

A 14-year-old girl with fever and low back pain was diagnosed as having brucellosis and diskitis. Treatment with doxycycline and gentamicin had no effect nor was there any improvement when the treatment was changed to doxycycline and rifampicin. With cessation of this treatment and administration of cloxacillin fever was reduced and the back pain disappeared. After 12 days of IV cloxacillin, she was released from hospital with instructions to continue cloxacillin orally for another 4 weeks. We conclude that when a patient is suffering from brucellosis and diskitis and does not respond to the usual anti-brucellosis treatment, an anti-staphylococcal preparation should be added.

We review various theories of the pathogenetic mechanisms of steroid-induced and essential hypertension. We investigated the possibility that a pathogenetic mechanism leading to glucocorticoid (GC)-induced hypertension or to mineralocorticoid (MC)-induced hypertension, or both, may be of critical importance in primary hypertension. We studied plasma levels of corticosterone (BK) and aldosterone (Aldo), and their concentrations in arterial and renal tissues of spontaneously hypertensive rats (SHR), a model of primary hypertension, and in the antecedent strain WKY rats as a normotensive control. Plasma levels of BK and Aldo were found to be normal and identical in SHRs and WKYs. Tissue (intracellular) levels of BK were more than double in SHRs than in WKYs. Subsequently we examined the activity of 11b-hydroxy steroid dehydrogenase (11-HSD) in both aortic and renal tissues of SHRs and WKYs. 11-HSD converts BK to the corresponding 11-keto compound, 11-dehydro-corticosterone (cpd.AK), which is inactive, in view of its inability to bind to the MC receptors (and also to the GC receptors). BK, the main glucocorticoid in the rat, as well as cortisol, have high affinity for the MC-receptor (MR). Normally BK or cortisol are present in 10²-10³ times greater concentrations than Aldo in tissues possessing MR. The enzyme 11-HSD deactivates BK (or cortisol), thus protecting MC-receptors in the MC target tissues from being activated by GC. When we examined arterial and renal tissue activities of 11-HSD in SHRs, the activity of 11-HSD was only one-third that found in the WKY rats. This explained higher levels of BK in the tissues of SHR, and suggested that decreased activity of 11-HSD is a pathogenetic factor for hypertension in SHRs.

Thus, in a model of primary hypertension such as SHR, decreased activity of 11-HSD in the target tissues of MC appears to lead to glucocorticoid-induced mineralocorticoid hypertension.

Kimura's disease is a rare angiolymphoid proliferative disorder of soft tissue characterized by subcutaneous swelling and a predilection for the head and neck. There are usually enlarged regional lymph nodes, eosinophilia and elevated sedimentation rate and IgE levels. A 26-year-old women with subcutaneous masses in the submandibular area is reported. The diagnosis of Kimura's disease versus angiolymphoid hyperplasia is discussed.

The dramatic course of necrotizing soft tissue infection represents a medical emergency, since it is limb - and life-threatening. Most necrotizing soft tissue infections are caused by mixed aerobic and anaerobic Gram-negative and Gram-positive organisms. Most case have been reported in immunocompromised hosts after penetrating trauma or surgery. We describe a unique series of cases of necrotizing soft tissue infection. The mainstay of treatment is early and daily debridement of devitalized tissue and broad-spectrum antibiotics. Hyperbaric oxygen therapy should be considered.

In the past 15 years there has been continuous increase in the use of injections into the corpora cavernosa of different vasoactive drugs for treatment of erectile dysfunction (ED). However, some of these drugs are very expensive, are not available everywhere, and have side effects. We therefore compared the success rate of the most widely used compounds, papaverine and regitine, in 452 patients (age range 26-85) with different types of ED. Each patient received in the clinic injections of papaverine, 6-25 mg, and regitine, 0.05-1.5 mg. When maximal rigidity of the penis (MRP) was >80%, we instructed the patient to self-inject the drug at home, 5-30 minutes before coitus. If after 3 injections MRP was not >80%, prostaglandin E1 (PGE1) in an average dose of 10-25 mcg was added. If there was no response, papaverin+regitine+PGE1 were given in higher dosage, and atropine sulfate, 0.02+0.06 mg, was added if necessary.

Of 452 patients, 305 (67.4%) had MRP >80% after 3 injections of papaverine plus regitine. The other patients received PGE1 in addition. This was helpful in 61 patients (41.5%), while 55 (63.9%) required papaverine + regitine + prostin in higher doses. Of these, only 31 received papaverine + regitine + PGE1 + atropine sulfate. Of these, 20 (64.5%) reached MRP >80%, and 11 (2.4%) MRP <60. For these 11 patients, we recommended a penile prosthesis. Thus in 67.4% of the 452 patients, papaverine + regitine injections were effective; in 41.5%, PGE1; in 63.9%, papaverine + regitine + prostin + atropine sulfate. Only 11 (2.4%) did not react to intracorporeal injection.

This progressive method of treatment enabled us to select the optimal dosage and combinations of compounds in 441/452 patients (97.5%) according to the severity of their dysfunction. During follow-up of 6 months, spontaneous erections without injection were achieved in 115 (26.0%).

18 patients suffering from persistent synovitis despite medical therapy were treated with an intra-articular injection of osmic acid. After 1 year of follow-up, 68% had good results and there were no complications nor detectable radiographic evidence of disease progression. Because osmic acid is almost as effective as surgical synovectomy and is cheap and easy to administer, it can be recommended as the first choice for treatment of corticosteroid-resistant arthritis in the early stages of the disease.

Pigmentary dispersion syndrome is a precursor of pigmentary glaucoma whose prevalence in the urban population of USA was found to be 2.45%. We evaluated its prevalence during ocular screening examinations among normal Israelis. We screened for excessive pigmentation on the corneal endothelium with the slit-lamp and determined in each patient best corrected visual acuity, intra-ocular pressure (after mydriasis), condition of the anterior segment, cup-disk ratio, posterior segment abnormalities and questioned about history of any ocular disease and family history of glaucoma. 374 patients (mean age 49±11) were examined on 10 consecutive days. In 5.9% excessive corneal endothelial pigmentation was found. Intra-ocular pressure (after mydriasis) averaged 15.52±1.93 mm Hg as compared to 14.73±2.04 among the rest of our study population, (p=0.01). The prevalence of suspected pigmentary dispersion syndrome among young adults in Israelis is high.

Six Cases of Acute Rheumatic Fever in One Year

George Habib, Ramiz Abu-Ahmad

Rheumatology Clinic and Dept. of Medicine, Nazareth Hospital; and Medical Dept. B, Carmel Medical Center, Haifa

During 1995, 6 cases of acute rheumatic fever were diagnosed here. Taking into account differences in total admissions, this appears to represent an increase over 1994. Most of the cases were males, with average age at diagnosis 19.5 years. All were of low socioeconomic status. 50% had cardiac involvement, and 1 needed treatment with corticosteroids. Most had pharyngeal symptoms prior to the acute attack, and 1 patient had 2 prior episodes of rheumatic fever. A thorough epidemiological study should be done in the Nazareth area to assess the real incidence of acute rheumatic fever, and to determine whether there is a true increase in incidence.

In 1994-1995, central venous lines were placed in 47 children. All except 1 were of the Broviac type, with subcutaneous tunneling via the internal or external jugular vein. Ages were between 7 days and 16 years. Indications for central venous cannulation were chemotherapy (35 cases), TPN (5), prolonged parenteral antibiotics (4), and repeated blood transfusions (3). The catheter was the source of infection in 13 children (28%), 11 of whom were immunocompromised. The commonly identified bacteria were Staphylococcus aureus (4 cases), Pseudomonas aeruginosa (4), coagulase-negative Staphylococcus (2), and various gram-negative rods (3). All cases were treated with antibiotics through the catheter. The most commonly used were oxacillin (4), ceftazidime (4), and amikacin (4). In 10, treatment succeeded without having to remove the line. In 2 others, tunnel infection developed and the catheter had to be removed. 1 child forcefully removed his catheter before treatment could be started. There were no further complications in the group treated conservatively, except for a case of superior vena cava thrombosis in a girl with recurrent infection of the tunnel. In 7 out of 13 treatment was continued and completed at home. This saved 65 days of hospitalization out of 210. We conclude that the conservative approach to treatment is feasible in most cases of infection when the source is the central venous catheter itself. However, when the tunnel is infected, conservative treatment may be ineffective. Treatment can be carried out in the home, with economy in cost and in use of hospital beds, and is preferred by patients and their parents.

Bromocriptine for Refractory Rheumatoid Arthritis

Reuven Mader

Rheumatic Disease Unit, HaEmek Medical Center, Afula

In recent years prolactin (PRL) has emerged as an important immunomodulator in various autoimmune disorders. Bromocriptine (BRC) is a dopamine agonist that suppresses secretion of PRL. Good clinical response to BRC has been reported in patients with psoriatic arthritis, Reiter's syndrome, and systemic lupus erythematosus. 5 mg of BRC at bedtime were given to 5 patients (aged 35-50) with refractory rheumatic arthritis (RA) who had failed to respond to previous treatment with at least 2 disease-modifying antirheumatic drugs. Patients were assessed at 4-6 week intervals for 6 months. 3 showed more than 25% improvement in the number of tender and swollen joints at 12 weeks of treatment. However, in only 2 of them was improvement maintained till the end of the 6 months. There were no changes in other measures of disease activity. 1 patient dropped out of the study due to acute exacerbation of her disease 4 weeks after initiation of BRC and required intra-articular injections of corticosteroid. The remaining patient did not show any significant clinical changes. No correlation was found between serum PRL levels and disease activity over time. It is suggested that some patients with refractory RA might improve with BRC. Its use in larger doses in larger groups of patients may help elucidate its role in the treatment of RA.

Implementation of Advanced Trauma Life Support (ATLS) skills among practicing physicians and its perceived utility in their civilian practices, as well as in their potential army combat assignments, was evaluated. 177 physicians in various subspecialties, who were graduates of ATLS training courses, answered a specially designed telephone questionnaire. An unexpectedly high percentage of physicians (47%) had used their ATLS training when called to treat trauma victims. 67% of physicians stressed the contribution of the ATLS course to enhancing their skills. We believe that a properly designed ATLS course for general practitioners would be very beneficial for trauma victims.

Diarrheal diseases weigh heavily on the health of children, especially in developing countries, but also impose burdens on health care services worldwide. This study was performed to determine whether patterns of referrals in the Negev to the pediatric emergency room (PER) for diarrhea differ between the Jewish and Bedouin populations of the Negev, and the extent of the burden imposed on the PER and in-hospital services in the Negev. Characteristics of referrals and hospitalizations were examined from March 1994 to February 1995. Of the 27,834 referrals to the PER for children under 16, 2518 (9%) had diarrhea and there were 5,169 hospital admissions, 701 (13.6%). The annual rates of referral were 146 per 10,000 in Jews and 225 in Bedouin, giving an odds ratio (OR) of 1.5 (p<0.001). for Bedouin. The rates of hospitalization were 23 per 10,000 in Jews and 99 in Bedouin (OR 4.4, p<0.001). 1380 (54.8%) of the PER referrals were of infants under a year of age. For hospitalization, the annual rates were 164 per 10,000 in Jews and 756 in Bedouins (OR 4.9, p<0.001). During June to August referrals and hospitalizations for diarrhea were significantly higher, and from December to February significantly lower than during the remaining months. These differences arise from the marked seasonal pattern in the Bedouin population, whereas in the Jewish population there was no seasonal variation. Even in the 90's the burden on health services in the Negev as a result of diarrheal illness is considerable and the Bedouin population still contributes to that burden disproportionately. There is need both to reduce the gap in referrals and hospitalization between the populations, as well as to reduce the rates, using currently available means such as education, while developing new technologies, such as vaccines.

Percutaneous endovascular techniques are well established procedures in the management of peripheral vascular disease and visceral arterial stenosis. They are now being adapted for use in the carotid artery as well. 8 patients with 9 extracranial carotid artery stenoses were successfully treated by percutaneous angioplasty, following which in 4 of them 5 stents were inserted. The stenotic lesions were situated in the proximal internal carotid artery and in its bifurcation and also in the common carotid artery. The indications for angioplasty in these patients were the same as for surgery. There were no major complications. 1 patient had transient hemiparesis lasting a few hours, and another had bradycardia following balloon dilatation in the region of the carotid body. Percutaneous endovascular treatment of carotid artery stenosis is becoming a safe, feasible alternative to surgery.
