Locoregional recurrence of rectal cancer ranges between 20%-50% following apparently radical surgery. Radiation has the potential of reducing this high rate of recurrence and residual disease. A retrospective analysis of 78 patients with locally advanced, biopsy proven, adenocarcinoma of the rectum treated between 1980-1987 was conducted. 28 (36%) were treated by surgery alone (surgery); 29 (37%) by surgery and postoperative radiotherapy (post-op); and 21 (27%) by surgery and preoperative radiotherapy (pre-op). 41 were females and 37 males. The median age was 62 years (range 25-90).

All tumors were resectable. 42 patients (54%) underwent abdomino-perineal resection and 36 (46%) anterior resection patients [8 Dukes B₁ (10%); 37 B₂ (47%); 2 C₁ (3%); 31 C₂ (40%]. Local recurrences were verified by transanal or ultrasound guided needle biopsy.

The 5-year actuarial survival rates by the Kaplan-Meier method for 75 evaluated patients was 55%. Overall 5-year actuarial survival was significantly higher (p=0.001) in pre-op radiotherapy (95%) compared to surgery alone (45%), or surgery with postoperative radiotherapy (32%). The data were significant (p=0.006) for patients with stage B tumors, but not stage C. This trend of improved survival held also at 8-year follow-up (80% pre-op; 32% post-op; 27% surgery). The 5-year actuarial local control was significantly better (p=0.03) for the pre-op irradiated patients (22%), compared with surgery only (56%) and post-op radiotherapy (38%). Local control was better (p=0.02) for Dukes B tumors in the preoperative group, but not Dukes C tumors.

Actuarial 5-year survival of those without distant metastases was 87% for pre-op patients, 62% for surgery alone and 48% for post-op radiotherapy. As all patients were clinically classified as advanced rectal tumors, tumor downstaging by preoperative radiotherapy seems to be paramount for local control. Improved local control translates into a siginificant advantage in overall actuarial survival.

The prevalence of hypersensitivity and untoward reactions to natural rubber latex (NRL) products is increasing, particularly among specific risk groups. A young man aged 23 years who experienced several episodes of allergic reactions, 2 of which included anaphylactic shock during hospital admission, is presented. These episodes were initially attributed to intravenous medication, but were most probably caused by inadvertent exposure to latex.

Medical facilities may contain large amounts of latex, and therefore present a hazardous environment for sensitive people. Increasing awareness of latex sensitivity among patients-at-risk and medical personnel, and implementing simple prophylactic measures, may reduce morbidity and mortality. We propose simple and practical guidelines for diagnosis and treatment.

Gyrate atrophy of the choroid and retina is a rare degenerative disease, characterized biochemically by a marked increase in blood ornithine levels, due to deficiency of ornithine S-amino transferase. 4 men aged 35, 36, 48 and 62 years are described with different stages of myopia, night blindness and loss of peripheral vision, which progressed to tunnel vision and partial blindness. Onset of the disease was at ages 3, 10 and 15 years, respectively, while in the 4th patient there was delayed expression starting at about age 50. Most had posterior subcapsular cataracts, and the ocular fundus exhibited demarcated circular areas of chorioretinal degeneration. So far the only patients described in Israel have been of Iraqui origin. Our fourth patient originated from Istanbul, and he may represent a hitherto undescribed variant with a much delayed expression of the disease.

Solid and papillary neoplasm of the pancreas is an interesting and rare malignant tumor. It occurs most commonly in young women. It was first described in 1959 and since then has been referred to by different names, including solid and cystic tumor, solid and cystic epithelial neoplasms, and others. Its malignant potential is low and metastasis is very rare.

Treatment includes partial pancreatectomy with full resection of the tumor. The prognosis is generally very good. We present 3 women (aged 17, 19, 39) diagnosed and treated for solid and papillary neoplasm of the pancreas. The unique clinical, histological, and epidemiological characteristics of this tumor are detailed.

Mitochondrial encephalopathies represent a heterogeneous group of various neurological syndromes caused by defects in mitochondrial metabolism. All clinical syndromes can be subdivided by type of biochemical defect into 3 subgroups: defective oxidation, defects in pyruvate metabolism and various defects in the respiratory chain.

We present a 12-year-old girl admitted for evaluation of progressive ptosis over a period of 3 years, diagnosed as having the rare mitochondrial encephalopathy, Kearns-Sayre syndrome.

It is clear to experts in the health care industry that with regard to medical decision-making, considering costs of medical devices is not a good index, but it is highly important to include medical aspects. This approach guarantees an advance and an appropriate method.

We present a cost-effectiveness analysis to target the optimal strategy of how to use medical diagnostic devices in cases of knee injuries. Today, one of the more common medical emergency referrals seen worldwide is in the area of orthopedics, knee injuries in particular. They can harm soft tissue, bone tissue, or both simultaneously. The diagnosis of soft tissue injury is difficult at best. Among the devices helping the clinician make an accurate diagnosis are MRI and ultrasound (US).

We conclude that US is superior to MRI in this condition. This is especially true when the orthopedic examination leads to the suggestion of arthroscopy. The results were not modified, and a sensitive study of the parameters that influence the decision- making process was undertaken. Decision-makers should not consider medical outcome alone, but should take into account the costs. A clinical study should validate the assumption on which this study was based.

Intractable pain is the most distressing symptom in nonresectable pancreatic carcinoma and in chronic pancreatitis. Recently, thoracoscopic splanchnicectomy has been advocated as a minimally invasive method of pain control in these patients. Between May 1995 and April 1998, 24 patients with nonresectable pancreatic cancer and 4 with chronic pancreatitis, underwent 43 thoracoscopic splanchnicectomies. All suffered from intractable pain, were opiate-dependent and unable to perform normal daily activities. Unilateral left splanchnicectomy was done in 13 and bilateral in 15.

All procedures were completed thoracoscopically. Operative time ranged from 25 to 60 min and mean hospital stay was 3 days. Median pain intensity was reduced by 50% in 24 and no further narcotics or analgesics were required. We found thoracoscopic splanchnicectomy a safe and effective procedure for intractable pancreatic pain.

Trauma increases risk of thromboembolic complications. Thus, in pelvic fractures and spinal injuries the incidence of deep vein thrombosis (DVT) is about 35-60%. Half occur in the pelvic veins and are the most likely to result in pulmonary embolism. While symptomatic pulmonary embolism occurs in 2-10% of patients, more have silent pulmonary embolism. 0.5-2% of pulmonary embolisms are fatal. In lower extremity trauma the incidence of DVT is about 58%, with 18% of them in the proximal veins. Thromboembolic complications are the prime cause of morbidity and mortality among trauma patients, yet they can be prevented efficiently and cost-effectively. The arsenal of prophylactic agents includes heparin, low molecular weight heparin, and mechanical devices including inferior vena cava filters.

Physiological Aspects of Women in Combat

Since military service is physically demanding, soldiers must maintain high levels of physical fitness for optimal performance of their duties. Women are at a physiological disadvantage when competing against men: they have a smaller muscle mass, more body fat, lower red blood cell counts, lower hemoglobin levels and smaller cardiac outputs. Women are slower and weaker than men and more prone to exercise-induced skeletal injuries. Fewer women than men meet the standards of physically demanding jobs. Therefore integrating women into physically demanding military-oriented jobs requires redesigning or modifying the tasks (different pace, mechanical aids, teamwork). While physical training can increase the physical capacity of women, training cannot completely eliminate gender differences. Thus the data presented do not imply that women cannot be integrated into combat units, but highlight gender-related differences which might have an effect on the ability of women to compete equally with men at the same task.

Airway obstruction during infancy and childhood requiring surgical ablation is rare, and surgical intervention poses a significant challenge. During recent decades, appropriate endoscopic instrumentation, together with advanced laser beam technology have provided new operative modalities for such patients.

From 1993 to 1995 we treated 40 infants and children, 26 males and 14 females, 13 days to 11 years old (mean 3.3 years) with Nd-YAG or CO² laser. Obstructing lesions included granulation tissue or polyps (16 cases), septa or webs (27), or benign tumors (4). 7 had more than a single lesion.

All were treated endoscopically under general anesthesia without any operative or postoperative deaths. Surgical intervention removed the obstruction and related symptoms in 34. In 6, laser treatment failed, necessitating additional surgical procedures. 3 had circumferential subglottic web. Operative complications included bleeding during removal of a hemangioma in 1 and recrudescence in another. Postoperative complications were transient respiratory failure and pneumonia in 6, all of which resolved with appropriate treatment.

This series proves that laser technology is feasible in the treatment of airway obstruction during infancy and childhood, and is safe and effective.

Laparoscopic adrenalectomy has recently been shown to be safe and effective for a variety of benign adrenal tumors, such as aldosterone adenoma, pheochromocytoma, nonfunctioning adenoma, Cushing's adenoma and Cushing's syndrome. Recently, laparoscopic surgeons adopted an extraperitoneal approach in which a space is created by the introduction of a trocar with an inflatable balloon tip. This technique with a minimal access procedure provides direct access to the adrenal glands without interfering with intraperitoneal organs.

Laparoscopic adrenalectomy using the extraperitoneal approach was completed in 18/20 consecutive patients. Mean operative time was 95 min (range 80-120) and median hospital stay 3 days. Blood transfusion was not required, and there were no postoperative complications.

Many drugs used in children are based on pharmacological data obtained in adults. Therefore, many drugs are either unlicensed for use in children or are prescribed outside the terms of the product license (off-label). This pilot study assessed use of unlicensed or off-label drugs in hospitalized children.

Drug orders of patients admitted to a general pediatric ward were reviewed retrospectively in a random sample. Assessment was based on the data of the Physicians' Desk Reference and the Israel Drug Compendium. 80 different drugs and 278 drug orders were written for 92 patients (0.5 months - 11 years old, mean 26.9 months) in 97 admissions. Of these 52.9% were either off-label or unlicensed. Patients received 1 or more unlicensed or off-label drugs in 64.9% of admissions. They were more often off-label than unlicensed. The main reasons for use of off-label drugs were unusual doses and inappropriate age. The main reason for unlicensed drugs was modification of a particular formulation of a licensed drug.

This pilot study indicates that use of drugs in an off-label or unlicensed manner in children is probably quite frequent in Israel. Our data emphasize the need for licensing a large number of drugs for use in children, based on the same scientific principles as in adults. Further collaborative studies in different pediatric centers in Israel, involving different types of pediatric settings (ambulatory and in-hospital), is required to evaluate comprehensively the magnitude of this preliminary finding.

The records of 537 patients with 750 maxillofaciafractures were reviewed and analyzed. 55 (10.2%) had sport-related injuries and the rest were due to othercauses. The sport-related group was predominantly male (ratio 9:1) with a mean age of 24.5 years. The mandible was most commonly injured (52.5%), followed by the zygomatic complex (32.8%). The incidence of complicated mid-facial fractures was only 2.8%, and of comminuted fractures 9%. This distribution of injuries is most likely due to the relatively low-energy of trauma associated with many sport activities. The relatively low mean age of the patients, most of whom had full dentition, allowed for conservative treatment of most of the mandibular fractures, using closed reduction.

Injuries were caused by 11 different sports. The highest incidence was soccer (45%), followed by skating (15%), basketball (9%) and horse-riding (9%). Contact sports were the cause of injuries in 72.2%, with the highest incidence of trauma due to impact with another player (60%). Better protection of the oral and maxillofacial region is needed, especially during high-contact sport.

Cervical pregnancy is a rare but serious complication. The most frequent presenting symptom is vaginal bleeding, and is thus common in inevitable abortion. Examination reveals a dilated cervix containing products of conception derived from the emptied uterine cavity. The pathologic criteria are cervical glands opposite the placental site, attachment to and actual invasion of the cervix by the placenta, a portion of the placenta below the posterior reflection, and no fetal parts in the corpus uteri. Treatment ranges from hysterectomy to treatment with chemical agents, mostly methotrexate. We present a case of ectopic, cervical pregnancy with exaggerated placental site in the cervix.

Pancreatic lesions present a diagnostic challenge. Even modern imaging techniques are not sensitive enough in determining resectability of pancreatic tumors. A substantial proportion of patients therefore undergo unnecessary surgical exploration. We determined the impact of laparoscopy and laparoscopic ultrasound (LAPUS) examinations on surgical decision-making in 60 patients with pancreatic lesions.

Of 48 with solid pancreatic lesions, 22 were defined by LAPUS as having nonresectable tumors, while conventional imaging studies defined only 9 of them as such. 3 of these 9 underwent successful resections of the pancreatic mass. Surgical intervention was ruled out by LAPUS in 16 patients (33.3%) but 26 had resectable lesions of whom 25 underwent surgery. 3 of this group were found to have nonresectable tumors at surgery, a false-positive rate of 6.2%. Overall sensitivity of LAPUS in our series was 88%.

In 12 patients with cystic pancreatic lesions LAPUS contributed significantly to the preoperative decision due to clear imaging of the cystic lesion. Additional information was obtained from ultrasound guided-biopsy of the cyst wall, as well as determination of tumor-marker levels in the cystic fluid aspirate. LAPUS contributed significantly to operative management in 58%.
