The increased rate of cesarean sections in recent decades has brought with it an increase in the frequency of placenta accreta. There are direct correlations between previous cesarean deliveries and also maternal age, with the risk of placenta accreta. There is also a direct correlation between placenta accreta and placenta previa.

The risk of placenta accreta in women who have had placenta previa is 2% for those younger than 35 years and with no history of uterine surgery. The risk increases to 39% for those over 35 who have had 2 or more cesarean sections.

We present 3 cases of placenta accreta admitted in 15 months, all of whom had a history of cesarean sections. The frequency of placenta accreta in our hospital is 1:1,579 deliveries, in line with the 1:1,420 in the literature. We consider hysterectomy the treatment of choice for this serious complication. When performing a cesarean in cases of placenta previa with a history of cesarean sections, the possibility of placenta accreta should be considered.

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.

There are 2 stages of alopecia, anagen and telogen effluvium, both of which may be associated with medication- related alopecia. We describe massive hair loss in a 51-year-old woman during treatment with Seroxat (paroxetine), which remitted after it was discontinued. Pathological mechanisms of drug-associated alopecia are complex and have yet to be fully elucidated.

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.

The rich blood supply of the stomach protects it from ischemia and necrosis. Acute gastric ischemia, an emergency with high mortality, is rare. Atherosclerosis is the leading cause of acute ischemia, and the lesser curvature of the stomach is more vulnerable due to its relatively lesser blood supply. Reduction in gastric blood supply usually presents as chronic disease characterized by gastritis, gastric ulcer, or gastroparesis.

Gastroscopy can identify lesions of the gastric mucosa, and angiography demonstrates occluded vessels. Treatment of acute gastric ischemia is surgical, with total gastrectomy preferred over partial resection.

Constant advances and increasing experience in laparoscopic surgery renders it applicable for adrenal surgery. The wide exposure required for open adrenal surgery makes this minimally invasive procedure an attractive and advantageous alternative.

Between 1996-1999, we performed 35 laparoscopic adrenal-ectomies in 30 patients 20-72-years old. Indications included: Conn's syndrome - 14, pheochromocytoma - 11, Cushing's syndrome - 6, nonfunctioning adenoma - 3, and metastatic sarcoma - 1.

5 underwent bilateral laparoscopic adrenalectomy. In 3 (8.5%) the procedures were converted to open operations. Overall morbidity was 13% and there was no mortality. Mean operative time was 188 minutes, but only 130 in our last 10 cases. Mean hospital stay was 4 days and they returned to normal activity an average of 2 weeks later.

According to our study and previous reports, laparoscopic adrenalectomy is feasible and safe and it may soon become the procedure of choice for adrenal tumors.

Deep sclerectomy (DS) can be used in glaucoma with increased intraocular pressure when medical treatment fails. It involves removing part of the ocular drainage apparatus. Resistance to intraocular fluid drainage is decreased, improving drainage and decreasing intraocular pressure. By avoiding anterior chamber penetration, DS diminishes frequency of the complications of filtering surgery.

24 eyes of 23 patients underwent DS for primary or secondary open angle glaucoma with elevated intraocular pressure not controlled medically. It included preparation of a 4.0 x 4.0 mm limbal-based external scleral flap, dissecting and removing most of an internal scleral flap (leaving it 1 mm smaller than the external flap), unroofing Schlemm's canal and removing fine endothelial tissue lining its inner walls. The external scleral flap was then repositioned and sutured. Collagen implants were not used. In some cases DS was combined with extracapsular cataract extraction and intra-ocular lens implantation.

Mean intraocular pressure decreased from 24.8‏3.9 mmHg initially to 12.8‏4.4 mmHg 6 months after operation (p<0.0001). There was no difference in postoperative intra-ocular pressure between DS as a single procedure or as part of a combined operation. Comations were mild and of short duration.

If long-term follow-up shows that lowered intraocular pressures are maintained, DS should be a surgical option in earlier stages of glaucoma.

37 candidates for epilepsy surgery underwent the intra-carotid amytal procedure (IAP; also known as the Wada test) to determine hemispheric speech dominance and memory capacity. 31 demonstrated left hemisphere speech dominance, 2 showed evidence for bilateral language and 4 demonstrated right hemispheric language dominance.

Our study supports a correlational relationship between handedness, lesion laterality and age of onset of seizures, as reported in earlier studies. Left-handed patients with a left hemisphere lesion whose seizures began to an early age had a strong tendency for reversed language dominance.

Asymmetry of at least 20% in performing the memory test was taken as the cutoff score for demonstrating laterality of lesions. The asymmetry score correctly predicted laterality of lesions in all 28 patients; 6 did not have asymmetry scores and 3 were examined for language only. None of the patients who successfully passed the Wada memory test had any significant postsurgical memory deficits; 1 had transient reduction in verbal memory and 4 who did not pass the test were not operated on for this reason.

Our results demonstrate the importance of the Wada test in determining cerebral speech dominance, in predicting post-surgical amnesia, and support its usefulness in predicting laterality of seizure focus in candidates for temporal lobectomy.

Physicians' Assessment of Computerized Prescribing

Prescription errors are a major source of preventable adverse drug events. Computerized prescribing (CP) which screens physicians' order for mistakes, drug-allergy, drug-disease, drug-laboratory and drug-drug interactions can prevent many of these errors and improve quality of care. However, computerized systems are often time-consuming, difficult to handle, and may create their own mistakes.

Following the introduction of CP on an internal medicine ward, we administered a questionnaire to evaluate physicians' opinions about the new system. The survey assessed computer literacy, ease of using CP, effects on time management, opinion of users regarding error prevention, and usefulness of the information provided. Opinions were generally favorable; most users felt that CP makes their work more accurate, reduces errors, is easy to learn and to use, and provides important and useful information. Physicians were most critical of equipment failure and drugs and dosages not included in the CP program, a result of rapid development of the system.

Errors resulting from the use of CP were considered minimal. Comparison of physicians, with and without previous experience with computer work, as well as local and foreign graduates, revealed minor differences. But once physicians learn to work with a well-organized CP system and computerized work stations, they appreciate the order, safety and knowledge they provide.

A case of carbon dioxide gas embolism during laparascopic cholecystetomy is presented. Prompt diagnosis and immediate treatment resulted in positive outcome. Laparascopic cholecystectomy is nowadays one of the most common operations for cholecystectomy and certainly the most frequent endoscopic surgical procedure. It is usually safe and effective. However, a number of serious complications have been reported during the procedure.

Gas embolism is one of the complications that may occur during the initial gas insufflation or during dissection of the gall bladder. Symptoms are mainly related to the speed and the amount of gas that reaches the venous system. Early recognition and prompt treatment are required to prevent severe morbidity or even fatal outcome.

Transesophageal echocardiography has detected many unsuspected cases of gas embolism. However, capnograph monitoring of end-tidal CO₂, routinely used in everyday anesthesia, is highly reliable in alerting to the possibility of gas embolism and also in confirming its occurrence.

In cases of suspected gas embolism close collaboration between anesthetist and surgeon is required.

Accepting and forgiving attitudes to the use of cannabis in its various forms, such as marijuana or hashish, are not justified, as they may result in dangerous mental health consequences.

A theoretical framework for this opinion is provided, including information on the various forms of cannabis available. Case studies presented exemplify possible complications resulting from use of cannabis or its derivatives.

Syme ankle disarticulation for foot infections in diabetics with concomitant peripheral vascular disease is often unsuccessful. The need for re-amputation usually results from recurrent infection or ischemia of the posterior heel flap. We present 5 such cases of deep foot infections in diabetics who underwent Syme amputation after failure of local debridement. All patients needed reamputation in 4-18 days for ischemia of the flap.

Unconventional Treatment of Severe Heart Failure in the Elderly

In the elderly, congestive heart failure is common and associated with significant morbidity and mortality.

Comprehensive management of heart failure improves functional status and decreases mortality. Diuretics remain the mainstay in treating congestive heart failure. However, some patients are resistant to diuretics. This is a serious problem as it seems to represent a final manifestation of congestive heart failure.

In an 85-year-old woman diuretic resistance was recognized as the cause of failure of conventional diuretic therapy. When the dose of furosemide was rapidly increased from 120 mg per os to 1000 mg IV within 4 days, diuresis began and there was dramatic improvement in her condition. The dose was then gradually decreased until a conventional maintenance dose of 200 mg/day per os was reached. This dose was sufficient to keep her heart failure under control.

Dept. of Medicine and Hypertension Institute, Wolfson Medical Center and Sackler Faculty of Medicine, Tel Aviv University

In a multicenter study in community clinics, 413 patients with mild to moderate essential hypertension were treated with cilazapril (Vasocase), 2.5 mg daily. Patients had either been untreated or had developed side-effects from previous antihypertensive treatment. When response was inadequate the dose was either increased to 5 mg or another antihypertensive medication was added, or both.

Treatment significantly reduced systolic and diastolic blood pressures. Pulse rate decreased significantly from the second month of treatment onwards. At the end of the 3rd month of treatment blood pressure was normalized or had decreased by more than 10 mmHg in 91.9% of patients. Physicians' evaluations revealed improvement in 62%; patients' self-evaluations suggested improvement in 61%. Efficacy was equal in all age groups and in both obese and nonobese patients. Antihypertensive response was superior in those with normal renal function. Side-effects were rare and similar to those reported in the literature.

Prioritizing Suspected Diagnosis of Both Brain and Abdominalinjuries: Is it a Problem?

Leon Levi, Moshe Michaelson

Dept. of Neurosurgery and Trauma Unit, Rambam Medical Center, Haifa

Current guidelines for management of suspected head and abdominal injuries are based on retrospective studies like that of Wisner & al, Following a recent review in this journal by Y. Kluger & al, which was based on non-Israeli data, we decided to define the current status at our trauma center.

We compare our data of 18 months of hospital admissions for acute trauma in which head CTs were done with those of 5 articles advocating specific protocols for decisions in pre-laparotomy diagnosis.

In the 861 cumulated cases, compared with the 800 of Wisner & al, craniotomy was required in 15% vs 7% (p<0.05); laparotomy was much less frequent, 2.7% vs 12.9% (p<0.05). The chance of finding a case requiring both craniotomy and laparotomy was 1 in 300.

As the clinical condition of multiple trauma involving the head and abdomen is becoming less frequent and includes diverse situations, a comprehensive algorithm might be inaccurate. Good clinical judgment of the clinician and teamwork are therefor preferable.
