CT-guided excision of osteoid osteoma is a new surgical technique that enables accurate resection of the nidus during 1-day hospitalization. We present 5-year results in 42 patients (26 males and 16 females, mean age 18 years, range 3-46). In 40 out of 42, complaints disappeared immediately after the procedure. The recovery period was short and the return to normal activity was faster than in the open surgical approach. Complications were minimal and transient.

Dept. of Oral Diagnosis, Medicine and Radiology, Hebrew University- Hadassah School of Dental Medicine, Jerusalem

Bulimia nervosa (BN) is an eating disorder frquently accompanied by changes of the hard and soft tissues of the oral cavity and of the salivary glands. Routine dental examination in a 25-year-old woman disclosed oral signs and symptoms characteristic of BN and she was referred for psychiatric evaluation. Oral evaluation of patients suspected of BN is recommended to prevent irreversible damage to the oral and perioral structures.

Irradiation Injury of the Salivary Glands

Dept. of Oral and Maxillofacial Surgery and Oral Biochemistry Laboratory, Rambam Medical Center and Technion Faculty of Medicine, Haifa

Ionizing irradiation of the salivary glands often leads to severe histological and functional alterations. Such exposure usually occurs during radiotherapy in patients with head and neck malignancy. The consequent xerostomia, often life-long, may result from even relatively low dosage irradiation, and causes a great deal of suffering. We suggest a radiobiological mechanism for this phenomenon which has been studied extensively since first described in 1911. The suggested injurious role of redox active transition metal ions and highly destructive free radicals is discussed in relation to the ultimate radiosensitive cellular target, DNA.

Reactive Increase in Blood Pressure on Immobilization, but not Hypertension, Prevents Pressure Ulcers

Vladimir Shats, Silvio Kozacov

Geriatric Dept., Rebecca Sieff Hospital, Safed

Of 135 geriatric patients immobilized for at least 2 days, 37 (27.4%) had pressure ulcers (PU). Those without PU were the control comparison group. Gender, length of immobilization, number of blood pressure determinations and proportion with hypertension were similar in those with and without PU. Those with PU were slightly older than those in the comparison group: 75.5±8.8 and 74.7±9.6 years, respectively (p>0.05).

Of 66 patients with acute ischemic stroke, reactive increase of systolic or diastolic blood pressure to 140/90 mm Hg or above following immobilization, was seen in 60.6% and 22.7% of patients, respectively, and there were PU in 12.1%. Of 17 with recurrent ischemic stroke, corresponding figures were: 41.2%, 23.5% (p>0.05), and 47.1% (p<0.01). In 7 patients with previous ischemic stroke corresponding figures were: 14.3% and 0% (p<0.01) and 100% (p<0.001). In 36 operated for fracture of the femur, corresponding figures were: 50%, 11.1% (p>0.05), and 27.8% (p>0.05). For 9 patients with severe infections, sepsis or pneumonia, the corresponding figures were: 22.2% and 0.0% (p>0.05), and 44.4% (p<0.04).

The proportion of patients with reactive increase in systolic blood pressure on immobilization was lower in the PU group than in the controls, 27% vs 59.2%, (p<0.001). The corresponding figures for reactive increase in diastolic blood pressure were similar, 8.1% and 20.4%, respectively (p>0.05).

The mean systolic blood pressure on immobilization was higher in the control than in the PU group, 145.4±21.7 and 130.8±14.9 mm Hg, respectively (p<0.001). The corresponding figures for the mean diastolic blood pressure were similar, 81.2±10.5 and 75.7±8.9 mm Hg, respectively (p<0.01). An increase in systolic blood pressure on immobilization reduced the risk of developing PU (p<0.05).

There was no significant statistical relation between diagnosis of hypertension and proportion of patients with PU (p>0.05). Of 67 patients with hypertension, in 23.9% and 74.6% of them there was no increase in systolic or diastolic blood pressure, respectively. Statistical difference between lack of diastolic or systolic response was very significant (p<0.001).

Reactive increase of blood pressure, but not hypertension, predicts reduced risk of PU on immobilization in the hospitalized elderly. Diminished reactive increase of blood pressure in response to stress of any kind may be a criterion of frailty and reduced physiological reserves. Efforts to reduce elevated blood pressure when a patient is immobilized appear irrational.

A-V Junctional Arrhythmia Due to Oral Phenytoin Intoxication

Dept. of Medicine A, Hillel Yaffe Medical Center, Hadera

Phenytoin (Dilantin) is the drug of choice for most of the convulsive disorders. However, even when given orally it causes many adverse reactions, mainly affecting the nervous system, both central and peripheral. When administered intravenously, severe cardiovascular reactions may occur, including conduction disorders, sinus arrest, atrioventricular block or hypotension.

Medline screening did not reveal previous reports of arrhythmias induced by oral phenytoin. We present a case in which oral phenytoin administered chronically for a convulsive disorder caused atrioventricular junctional arrhythmia.

Knowledge and practice of primary care physicians as to diagnosis and treatment of group A, b-hemolytic streptococcal pharyngitis, and the degree to which they agreed with the medical literature and current clinical guidelines were examined. The study was conducted in a group of 195 general physicians, pediatricians, and family medicine specialists and residents. The data were collected using questionnaires which included personal information and questions relating to b-hemolytic streptococcal pharyngitis and were analyzed by chi-square and t-tests, and logistic regression, as appropriate. A new dependent variable, good clinical practice (GCP), was defined as the total number of correct answers to the questions in the questionnaire. 147 of the 195 eligible physicians returned completed questionnaires, a compliance rate of 76%.

96.6% cited pV as the drug of choice at a daily dosage of 1 g (43.7%) or 2 g (25.4%), for 10 days (90%). 133 physicians (90%) stated that the goal of penicillin therapy for beta-hemolytic streptococcal pharyngitis is to prevent late complications. 116 physicians (82%) cited rheumatic fever as a complication of group A beta-hemolytic streptococcal pharyngitis, preventable by appropriate antibiotic therapy. However, only 84 (59%) cited glomerulonephritis as a preventable complication.

When the knowledge and attitudes of the respondents was analyzed in terms of the new variable, GCP, a significant association (p<0.001) was found between physicians’ attitudes and variables such as where they had studied medicine, and work seniority. Those with less seniority and or medical graduates of the Americas demonstrated greater knowledge and better clinical judgment than their more senior colleagues and graduates of European and Asian medical schools. Most primary care physicians in northern Israel treat group A b-hemolytic streptococcal pharyngitis as recommended in the medical literature.

The level of medical studies in Israel and the Americas and the quality of training of residents in family medicine and pediatrics, have a positive influence on the degree of knowledge of as common a subject as b-hemolytic streptococcal pharyngitis. Emphasis should be placed on continuing medical education among primary care physicians, particularly veteran general physicians and those who studied in European or Asian medical schools.

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.

Road accidents, work accidents, or other trauma can cause impotence and are frequently followed by insurance claims. During 1990-97 we examined 230 males with such a complaint. All underwent full polysomnographic recordings in the sleep laboratory for 2 nights, during the course of which NPT (nocturnal penile tumescence) was examined with special equipment. It was assessed by an experienced technician following planned awakenings from REM sleep.

In 75 of the 230 subjects (33%), satisfactory erections were observed. In 100 (43%), who experienced at least 3 periods of REM sleep, no erections occurred. These patients were categorized as suffering from organic impotence. In the remaining 55 (24%), the results were inconclusive, with only partial erections or not enough REM sleep periods.

Since a man recognized as suffering from impotence may be awarded large monthly payments for life, these examinations, in our opinion, are an important tool to prevent unjustified claims, and can save the state unnecessary expenses.

Cardiac Catheterization Unit, Schneider Children's Medical Center, Petah Tikva, and Sackler School of Medicine, Tel Aviv University

The use of balloon dilatation to treat native coarctation of the aorta is gaining acceptance among interventional pediatric cardiologists, but is still controversial. We describe our experience with this procedure in 21 children, mean age 5.6 years and mean weight 21.1 kg. Most had an additional congenital heart defect, most commonly a bicuspid aortic valve. 17 were asymptomatic, 3 had tachypnea and 1 infant had severe congestive heart failure and was ventilated. The mean systolic blood pressure was 129.7 mm Hg.

Balloon dilatation was successful in 90% (19), decreasing the mean maximal systolic gradient from 35.3 to 9 mm Hg (p<0.001), and increasing the narrowest area from 3.9 to 8.2 mm (p<0.001), with a mean balloon-to-coarctation width-ratio of 2.8. There were no complications. Of 15 who underwent repeat cardiac catheterization at a mean interval of 10.6 months, 2 had a maximal systolic gradient of more than 20 mm Hg. 1 of these underwent successful repeat angioplasty and the other, who also had a small aneurysm, underwent surgical repair successfully. 2 others had small aneurysms and they are being followed clinically.

All patients were seen again after a mean interval of 31 months. The mean systolic blood pressure was 104 mm Hg, significantly lower than before intervention (p<0.002). 1 had an increased pressure gradient between right arm and leg of 35 mm Hg at later follow-up, and repeat cardiac catheterization demonstrated a good result 13 months after the initial procedure. She is awaiting a third catheterization. Overall, 90% had good mid-term results.

Based on our experience and recent reports, balloon angioplasty is safe and effective in most children older than 7 months and should be considered a viable alternative to operation for discrete aortic coarctation. Further long-term evaluation is needed.

Major hepatic resections have been associated with significant morbidity and mortality. In the past decade or so this has changed and such procedures are now done in increasing numbers. In the past 5 years we operated on 129 patients with benign or malignant hepatic lesions (75 females, 54 males; age-range 14-84). the reason for surgery was malignancy in 94 (72.9%) and benign lesions in 35 (27.1%). The most common indication for surgery was liver metastases secondary to colorectal cancer in 45% of all patients or 61.7% of those operated for malignancy. Primary liver cancer was the cause for liver resection in 13.2% of all patients or 18.1% for those with malignancy. Of the 35 patients with benign lesions the leading causes for surgery included: giant cavernous hemangioma, simple liver cysts, echinococcus cysts and focal nodular hyperplasia (11%, 22.8%, 20% and 14.3%, respectively).

76 patients underwent anatomical resection and 63 had either a nonanatomical resection or a different operation. Among the former the most common procedure was right hepatectomy (36) and among the later a nonanatomical resection equal to 1-3 Couinod segments (44). Operating time ranged from 55 min. to 8:41 hours with a mean of 3:31‏1:37. Mean hospital stay was 8.7‏5.8 days and 86.8% received between 0-2 units of blood. Overall mortality was 6.2% and 31.2% of the fatalities had cirrhosis. Overall mortality in noncirrhotic patients was 2.6%. The complication rate was 16.3% and only 7 patients (4.4%) were hospitalized in the intensive care unit. This indicates that major liver resections can be done safely, with morbidity and mortality similar to that of other major abdominal operations.

Guillain-Barre and other neurologic syndromes rarely occur as complications of viral hepatitis (A, B and C). Other neurologic syndromes have also been reported in serologically defined viral hepatitis, including mononeuritis, auditory neuritis, and seizures. Chronic hepatitis B and mononeuritis multiplex are found together in 31-54% of patients with periarteritis nodosa. The mechanisms of these associations are unknown, but may include direct cytotoxicity of the virus or immune-mediated damage. Vasculitis of the vasa nervorum plays an intermediate role, at least in some cases. We describe a 36-year-old man with acute non A-G hepatitis complicated by Guillain-Barre syndrome. The neurological manifestation resolved completely without specific therapy within 6 days, as the hepatitis resolved.

Mesenteric and portal vein thrombosis are rare complications of splenectomy. Their presentation depends on the underlying disease. It is most frequent in lymphoproliferative disorders but extremely rare in trauma. We describe a 22-year-old man and a 49-year-old woman who underwent splenectomy for idiopathic thrombocytopenic purpura and developed mesenteric and portal vein thromboses. Both were treated successfully with anticoagulants for 3 months until the thrombi regressed, as shown by CT scan. During a year of follow-up they were asymptomatic.

Danaparoid sodium is an anticomposed of 3 glycosaminoglycans: heparan sulfate, dermatan sulfate and chondroitin sulfate. Similar to heparin, operates by activating antithrombin 3, but does not contain heparin or heparin fragments, and is therefore antigenically distinct.

Danaparoid has been advocated as a safe and effective anticoagulant for heparin-associated thrombocytopenia. However, there is little experience in its use as a substitute for heparin in hemodialysis.

We report 2 men, aged 82 and 73 years, respectively, who developed thrombocytopenia while undergoing hemodialysis with heparin, and who subsequently underwent successful dialysis with danaparoid. There was a rise in platelet levels in both while receiving danaparoid, and dialysis was completed without hemorrhagic or thrombotic complications. Danaparoid is a safe and effective substitute for heparin, and may be used as an anticoagulant in hemodialysis.

Inguinal hernias are common and have highly variable clinical presentations, ranging from the asymptomatic to surgical emergencies when incarcerated, sometimes necessitating bowel resection. Several techniques have been described for repair of inguinal hernias based on the unique anatomic structure of the inguinal region. In 1989 Lichtenstein and co-workers described a "tension free" repair based on using a synthetic mesh patch to reinforce the inguinal canal floor and as a plug to prevent recurrence through the internal inguinal ring. This technique has been used in many centers worldwide with good rates of success.
