Many patients mechanically ventilated for acute respiratory failure, are treated with medication that includes a combination of cortico-steroids and non-depolarizing neuromuscular-blocking agents (NNBa). A third of them can be expected to develop delayed neuromuscular damage, which may be severe and prolonged.

We describe a 50-year-old man who suffered from acute myeloid leukemia and was ventilated due to pneumonia. He was treated with pancuronium and cortico-steroids, and during recovery suffered quadriparesis that lasted several months.

Typically this damage is purely motor and is accompanied by absent tendon-reflexes, sometimes with elevated creatin-kinase. Muscle biopsy usually shows deletion and degeneration of thick myosin filaments. The phenomenon is related to the duration of NNBa treatment, and probably results from an adverse synergistic effect on muscle tissue of the cortico-steroids and cortico-steroid-like NNBa given the immobilized patient.

Awareness of this adverse effect of steroids and pancuronium, the use of passive mobilization, shortening the use of NNBa and early rehabilitation would minimize disability due to this phenomenon.

We assessed the incidence of drug abuse among patients requiring psychiatric hospitalization, and characterized the population at risk. The data on drug abuse were obtained from self-reports and urine tests in 103 patients, aged 18-65, hospitalized in the Kfar Shaul Psychiatric Hospital (autumn 1998).

There was close correspondence between the self-reports and the results obtained from urine tests. 1/3 admitted to having used illegal drugs and signs of drug abuse were found in about 1/4 of the urine tests. The most prevalent drugs were cannabis products (hashish and/or marijuana) and in 15 patients opiates.

Drug users were younger than non-users. With regard to psychiatric symptomatology, fewer negative symptoms were recorded among cannabis abusers with schizophrenia, compared to schizophrenic patients with no history, past or present, of cannabis abuse.

The present findings confirm the clinical impression that there has been an increase in drug abuse among mental patients, parallel to that found in society at large. Confirmatory surveys are necessary. Our findings clearly suggest that a change in attitude has occurred in Israel to what has been considered a marginal problem. Hospitalized mentally-ill patients, the younger in particular, should be considered at risk for drug abuse.

The War of Attrition between Israel and Egypt along the Suez Canal line lasted 23 months (9/1968-8/1970), during which the Israel Defense Forces (IDF) were mostly in fixed fortifications. A few of the important principles of field medical support, which became cornerstones of IDF procedure, were established during that war. These included use of armored vehicles for evacuation under artillery fire, as well as emergency treatment, physiological stabilization, and maintenance of the wounded until evacuation.

The latter objectives were achieved by stationing medical officers and paramedics within the fortifications, where they remained with the troops. A field surgical hospital was established in Refidim which had a trained surgical staff and a well-equipped emergency department. It included an operating theater and post-op recovery facilities for proper surgical care until evacuation to hospitals in the rear.

Tables showing the number of casualties throughout 1 year of the War of Attrition are presented. Better personal shielding by helmets and body shields decreased the number and severity of head and thoraco-abdominal injuries. The relative large number of those who died-of-wounds was due to the proximity of medical facilities, so that treatment could be administered within the fortifications. Otherwise, many more would have been included among the killed-in-action.

Etoposide and cisplatin (EP) has been the standard therapy for non-small cell lung cancer (NSCLC) at many cancer centers for over a decade. We analyzed our experience with EP in NSCLC to provide a baseline for comparison with new drugs. From 1986 through 1994, 46 of our patients with NSCLC received EP as first-line chemotherapy. Radiation therapy was administered to 25 of them, including 20 who received it immediately before or concomitantly with chemotherapy. Toxicity was mild and included only 1 episode of neutropenic fever and 1 case of reversible renal failure.

Overall response was 22%. In 3, response was complete (pathologically documented in 2 of them) and in 7 partial. Median survival in locally advanced (stage III) and metastatic disease (stage IV and recurrent) were 12 months and 7 months, respectively. 2 patients are alive and free of disease more than 6 years after diagnosis.

Our results are consistent with other published studies of EP in NSCLC. EP provides modest benefit in locally advanced NSCLC, with minimal toxicity.

Age over 80 years is generally considered an independent risk factor in elective surgery for abdominal aortic aneurysm (AAA). As the general population increases in age, more elderly are likely to be candidates for such surgery.

We studied prospectively 100 consecutive patients undergoing elective AAA surgery between 1992-1995. All were operated on by the same team of anesthetists and surgeons and all were transferred to the general ICU for at least the first 24 hours. 16 were above the age of 80 (Group I) and 84 below (Group II).

We recorded preoperative factors (demographics, medical history, risk factor indices, EKG findings, as well as left ventricular ejection fraction (LVEF) and stress imaging when indicated); intraoperative factors (duration of surgery, size of aneurysm, complications and units of blood transfused); postoperative factors (length of ICU stay, duration of ventilation, APACHE II [Acute Physiological and Chronic Health Evaluation] and TISS [Therapeutic Intervention Scoring System] scores; complications in the ICU, need for readmission to the ICU, and mortality).

In Group I LVEF was greater (p=0.03) and aneurysm size significantly larger (p=0.036), but there were no other significant differences between the 2 groups with regard to pre- and intraoperative data. Group I patients were not ventilated as long (p=0.038), but there were no significant differences in outcome factors. Mortality for the whole group was 5% and was not significantly different in the 2 groups (1/16 in Group I and 4/84 in Group II).

We conclude that there is no excess morbidity or mortality in octogenarians undergoing AAA surgery. However risk of the aneurysms rupturing is significantly greater since they are larger. We suggest that age not be considered the sole criterion for aneurysm repair, or at least not in selected patients with normal LVEF.

Brachytherapy is especially suitable for palliative treatment of endobronchial tumors adjacent to internal organs that might be damaged by intensive external beam radiation, but are easily accessed with a flexible bronchoscope. This treatment is mostly palliative.

30 patients underwent such palliative high-dose endobronchial brachytherapy to alleviate malignant airway obstruction. With the aid of a flexible fiberoptic bronchoscope an endobronchial catheter was inserted adjacent to the tumor and treatment delivered using a 192Ir remote afterloader for 5-10 min, in 2 or 3 sessions.

There was symptomatic improvement in 26 (86%) and objective improvement in 27 (90%). 1 patient died of hemoptysis.

Acute epidural hematoma is very rare in the elderly after head injury. It is usually associated with extremely high mortality or severe disability. In an 87-year-old woman a large, hyperacute, epidural hematoma was diagnosed. She was treated promptly and enjoyed an uneventful, complete recovery. This exceptional case should encourage an intensive approach even in seemingly minor head trauma in the elderly.

Therapeutic injection of botulin toxin is well-recognized for reducing tonus in local dystonia. However, its efficacy in reducing spasticity in spinal cord injuries is still unproven. 4 men and 1 woman (mean age 39 years, range 20-56) with spinal cord injury and debilitating spasticity, and no response to standard treatment for spasticity received injections of botulin, 200-300 U, into 4-8 points in their legs to block muscle-nerve synapses.

In all 5 tonus was reduced in the area of the block, while in some it was also reduced in more distal muscles. In 1 there was reduced tonus in both the injected and contralateral leg. The therapeutic effect on tonus persisted for 3 months. In spite of objective improvement in tonus in all 5, only 3 felt subjective improvement, but in none was there improvement on standard functional scaling.

We found injection of botulin toxin effective in reducing tonus in the spinal cord-injured, and to some extent in improving subjective feeling of well-being in some of them. Obective measurement might show functional improvement after larger doses of toxin injected into more muscles. This might be necessary because the muscle mass of the legs is large and the intensity of involuntary contraction is especially high in these patients.

Endoscopic Sinus Surgery for Extracranial Complications of Sinusitis

E. Deutsch, I. Hevron

ENT Dept., Bikur Cholim Hospital, Jerusalem

Orbital subperiosteal abscess (SPA) and Pott's puffy tumor (PPT) are the major extracranial complications of acute sinusitis. These complications are aggravated by the close anatomic relationships between the nasal sinuses and the orbits and frontal bone. Furthermore, the rich diploic venous drainage of the region enhances the spread of the infection.

Between 1992 and 1997, 16 patients (mean age 12 years, range 2-15, 10 of them males), 11 of them with SPA and 4 with PPT were operated on by the senior author by means of endoscopic sinus surgery (ESS). Indications for operation included: CT findings of abscess formation and lack of clinical improvement after 48 hours of IV antibiotic therapy. Clinical resolution of symptoms was achieved in all and there were no operative or postoperative complications.

We emphasize and explain the advantages of ESS over external approaches in surgery for extracranial complications of acute sinusitis by several facts: the technique treats the source of the disease, clinical success rate is high, morbidity is low, and facial distortion and poor cosmetic results completely avoided.

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.

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.

Hepatocellular carcinoma (HCC) is a common malignancy with a grave prognosis. Most patients have both the malignant tumor as well as hepatic cirrhosis. Liver transplantation or hepatectomy are considered the only curative procedures, but can be applied in fewer than 10% of patients. In recent decades the most common treatments of HCC are transarterial chemoembolization with oil (TOCE) and percutaneous ethanol injection (PEI). We summarize our retrospective study of 100 patients (mean age 64) 3‏ treated by TE.

In 271 procedures between 1989-1998, in 16 patients hepatectomy was combined with TOCE and in 8 PEI was combined with TOCE, while the rest were treated by TOCE alone. Tumor mass was reduced in 36% of those treated by TOCE (tumor volume reduced 24-75%). Alpha-feto protein (AFP) was reduced 25-90% in 20/32 of those with elevated AFP levels. Median survival for the 100 in the entire group was 19 months (10.9 months in those with conservative treatment). Median survival in the 57 in Okuda stage 1 and the 43 in stages 2 or 3 was 30.1 months and 10.9 months, respectively (p<0.0001). Of the 57 in stage 1, 16 underwent hepatectomy in addition to TOCE and 41 were treated only by TOCE (median survival 15 and 26 months, respectively, p not significant).

Comparing Okuda 1 patients treated by TOCE only with the natural history of the disease and historical controls (Okuda 1 patients treated conservatively in 1984) median survival was 26 and 10 months respectively (p<0.001). The side effects of TOCE were relatively mild. There was 1 fatality (3 days after treatment), and quality of life was maintained. Despite progress in the treatment of HCC by TOCE, PEI, and liver transplantation, long-term survival has remained unsatisfactory.

Acquired infection with hepatitis C virus (HCV) in hemodialysis patients has been described lately. In dialysis units in Italy and France, the prevalence and incidence of HCV are 20-60% and 1-2%, respectively. Most infected patients develop chronic hepatitis. The clinical presentation of acute HCV in hemodialysis patients is very mild and therefore the diagnosis is often made only by laboratory tests. Acute infection is usually followed by mild elevation of liver enzymes and the presence of HCV-RNA and anti-HCV in serum.

We report a 48-year-old man on hemodialysis who developed acute hepatitis C. The diagnosis was made by finding mild elevation of liver enzymes and the presence of HCV-RNA in his serum. A few months later, he developed severe hepatitis which was followed by rapid deterioration in liver function. However, the virus was eradicated and liver function tests became normal. Surprisingly, serum anti-HCV antibodies were detected 5 months later.

Low back pain radiating to a limb is usually caused by lumbar disc herniation. Tumors of the spinal cord or near the sciatic or femoral plexus can cause neural compression and clinical signs similar to those of disc herniation. Such tumors are usually misdiagnosed as discal herniation and appropriate treatment is delayed. We present 4 men who had tumors causing low back pain radiating to the leg: a 70-year-old with metastatic squamous cell carcinoma of the lung, a 20-year-old with aneurysmal bone cyst of the vertebral column, a 52-year-old with retroperitoneal sarcoma and a 32-year-old who also had retroperitoneal sarcoma. Diagnosis and trwere delayed because the clinical symptoms were ascribed to lumbar disc herniation. The latter 2 patients had CT-scans showing lumbar disc herniation, but similar findings are common among asymptomatic individuals.

The differential diagnosis of low back pain radiating to the leg should include tumor when there is a history of cancer, pain not relieved by conservative treatment nor by lying down, pain is increased at night, pain accompanied by weight loss, and when physical examination demonstrates injury to more than 1 nerve root. In these circumstances work-up should include EMG, radioisotope scan and CT of the pelvis.

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.
