Attentional Characteristics of Developmental Right Hemi-Sphere Syndrome

Neuropediatric Unit, Shaare Zedek Medical Center, Jerusalem

Developmental right hemisphere syndrome (DRHS) is characterized by emotional and interpersonal difficulties, attention deficit hyperactivity disorder (ADHD), visuo-spatial handicaps, subtle left body neurologic signs and failure in nonverbal academic domains, especially arithmetic. Concurrence of ADHD and DRHS is not surprising because research has implicated dysfunction of the right hemisphere in both syndromes. Furthermore, the right hemisphere has more brain areas devoted to attentional processing, making it more important and more vulnerable in attentional problems.

We describe the clinical parameters of DRHS as exemplified by 2 cases, a boy and a girl, both 13 years old. They participated in a study group in which attention and speed of performance were assessed in children with DRHS and were compared to children with ADHD and to a control group. A tendency to overfocusing, difficulty in inhibition, perseverative behaviors, stereotypy, and slowness and absence of hyperactivity characterized the DRHS group. These behaviors led us to hypothesize that the attentional symptoms in DRHS define a specific subgroup of ADHD which requires a different therapeutic approach.

Stress urinary incontinence is a medical and social problem. In the past decade there has been increased awareness of this condition and the number of those affected who seek help is increasing. Treatment is usually surgical - elevation of the bladder neck. Pelvic floor exercise is an accepted conservative treatment modality used for mild to moderate cases that have not yet completed their families.

We present our results in 30 women, aged 28-71 years, av. 49% with genuine stress incontinence treated with pelvic floor exercise and biofeedback. 14 patients (46.7%) were completely cured and 15 (50%) were improved. In only 1 was there no improvement.

Our results show significant improvement in the duration and intensity of pelvic floor contractions after treatment. Pelvic floor exercise with biofeedback is a very important treatment modality, requiring a highly motivated patient and a physiotherapist specialized in pelvic floor exercise.

Soft tissue sarcomas are exceedingly rare, making up less than 1% of all solid malignancies. In the retroperitoneum, they tend to be large when diagnosed and are a therapeutic challenge to the surgical oncologist. Our experience with 51 patients with retroperitoneal sarcomas operated on during the past 4 years is presented. 37 were primary and 26 presented as recurrent tumors. The group included many different histological sub-types, the majority being high grade tumors.

Complete resection was achieved in 84%, necessitating extensive surgery, but was not possible in 8 patients (16%) who underwent partial resection or biopsy only. There was 1 perioperative fatality (2%). 18 (35%) suffered complications, all of which were reversible. The estimated 5-year survival in the complete resection group is 40%, while none of those who underwent partial resection survived more than 2 years. There was significantly better survival in patients with primary, low grade sarcomas which were smaller than 8 cm, compared to those with high-grade, recurrent sarcomas larger than 8 cm. Local recurrence developed in 8 patients of the complete resection group (18%), 2 months to 3 years after surgery.

These data show that despite the concept of retroperitoneal sarcomas as being aggressive, invasive tumors with a poor prognosis, the prognosis is not unusually bad. With proper surgical technique, resectability may be high, with improved overall survival.

Malaria is 1 of the main causes of death in third world countries. It has become extinct in Israel and imported cases are rare, since most visitors to endemic countries take anti-malarial prophylaxis. We report an Israeli tourist to Kenya infected with falciparum malaria complicated by severe metabolic acidosis, renal failure and adult respiratory distress syndrome. After intensive care treatment this preventable condition improved.

Plagiocephaly in a head-and-neck irradiated rat model or rhomboid-shaped head, occurs in at least 1 in 300 live births. In most cases such asymmetry is not caused by synostosis of the unilateral coronal or lambdoid sutures, but is rather a deformity produced by intrauterine and/or postnatal deformational forces. Categorization and diagnosis of plagiocephaly as synostotic or deformational is reliably made by physical examination and computerized tomography. Its differential diagnosis is extremely important because prompt surgical correction is usually indicated for the synostotic type. In contrast, infants with deformational frontal or occipital plagiocephaly generally respond to helmet treatment.

10 infants with significant deformational plagiocephaly were treated with individual plastic helmets during the past 2 years and 4 other infants with plagiocephaly are currently being treated. In each instance, cranial asymmetry dramatically improved as the brain grew and the head filled out the helmet. There were no significant complications. Awareness of deformational plagiocephaly allows more accurate diagnosis and appropriate treatment, avoiding unnecessary surgical intervention in patients with positional molding.

Irradiation Injury of the Salivary Glands

R. M. Nagler

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.

Smoking is the dominant risk factor for lung cancer. We compared trends in smoking with those of the incidence of lung cancer in Israel. The proportion of smokers has declined during the past 20 years; the decrease is greater in men than in women, and more marked in the elderly. Since 1980 the age-adjusted incidence of lung cancer in Jewish men has decreased slightly, but in women it has remained constant. Among Arab men there was an increase in age-adjusted incidence of lung cancer and since 1986 it has been higher than in Jewish men.

The largest decrease in lung cancer incidence was among Jewish men aged 75 and over. This may be explained by data on the age of smoking cessation in the population. It was observed that the main decrease in smoking occurred among men over the age of 55 in the past 20 years, which correlates with the decline in lung cancer observed in the older age group. Lung cancer rates in Israel are lower than in other western countries despite the similar prevalence of smoking, for unknown reasons.

A-V Junctional Arrhythmia Due to Oral Phenytoin Intoxication

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.

Hepatitis A is one of the most frequently reported notifiable infectious diseases in Israel. The annual incidence as reported is around 70/100,000. The physician or the diagnostic laboratory notifies the district health office of the Ministry of Health.

The purpose of this research was to evaluate the sensitivity of passive surveillance of hepatitis A morbidity among adults, 18 years and over. Methods included study of notifications to the Ministry of Health or hospitalizations of cases of hepatitis A and of positive laboratory tests results (IgM) for hepatitis A. We estimated the extent of under-reporting by 2 different methods of extrapolation.

Data based on passive surveillance among the adult population, between 1.1.1993-31.12.1994, comprised less than 1/5 of the actual number of cases. Physicians notified about 6.2% of their hepatitis A patients. 5.1% of the notifications to the district health office were sent twice or more, usually both by the physicians and labs.

The official data on hepatitis A morbidity, based on passive surveillance, are considerably underestimated. Physicians and public health officials should be aware that such data may not accurately reflect the magnitude of the risk or the amount of disease that can be prevented. Efforts should be made to improve this situation.

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.

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.

The development of laparoscopic surgery in gynecology and general surgery has greatly advanced over the past decade, and recently has been successfully performed in pregnancy. In the English literature we found that of the 518 cases reported (mean age 32 years) the most common was for cholecystectomy (45%), followed by operations on the adnexae (34%), appendectomy (15%) and others (6%). To these we add 3 cases of cholecystectomy and 1 of an adnexal tumor. Of all the reported cases, 33% were performed in the 1st trimester, 56% in the 2nd and 11% in the 3rd.

This review demonstrates a definite trend to laparoscopy in pregnancy. It appears to be safe when performed by experienced surgeons, but further studies addressing safety of laparoscopic surgery during pregnancy are needed to reach definitive conclusions.
