Background: Chlorpromazine is a dopamine-receptor antagonist antipsychotic agent. Because of its strong alpha-blocking and sedative actions, it has also been used as emergency therapy for extreme arterial hypertension. Published reports to date have included very small numbers of patients (i.e., 5–30).

Objectives: To analyze data on almost 500 patients who received intravenous chlorpromazine for the emergency treatment of uncontrolled symptomatic hypertension in the pre-hospital setting.

Methods: We reviewed data from 496 consecutive patients who received intravenous chlorpromazine as emergency therapy for uncontrolled symptomatic hypertension. Chlorpromazine was injected intravenously. The dose was 1 mg every 2–5 minutes until the systolic pressure was -<140 mmHg and the diastolic pressure -<100 mmHg with alleviation of symptoms.

Results: The mean dose of chlorpromazine administered was 4.5 +- 5 mg (range 1–50 mg). Only 33 patients (7%) required >10 mg. Chlorpromazine reduced the systolic blood pressure from 222.82 +- 26.31 to 164.93 +- 22.66 mmHg (P < 0.001) and the diastolic blood pressure from 113.5 +- 16.63 to 85.83 +- 11.61 mmHg (P < 0.001). The sinus rate decreased from 97.9 +- 23.5 to 92.2 +- 19.7 beats per minute (P < 0.001). These results were achieved within the first 37 +- 11 minutes.

Conclusions: Intravenous chlorpromazine is safe and effective when used as emergency treatment for uncontrolled symptomatic hypertension.

 Background: Pelvic fracture poses a complex challenge to the trauma surgeon. It is associated with head, thoracic and abdominal injuries. As pelvic fracture severity increases so does the number of associated injuries and the mortality rate.

Objectives: To report our experience in the treatment of pelvic fractures.

Methods: Between October 1998 and September 2001, 78 patients with pelvic fractures were admitted to our hospital. The age range of the 56 male and 22 female patients was 16–92 (mean 42 years). The cause of injury was road accident in 52 patients, fall from a height in 15, a simple fall in 9, and gunshot wounds in 2 patients. The Glascow Coma Scale score on arrival at the hospital was 3–15 (average 12). Twenty-five patients (32%) were admitted to the intensive care unit, 38 (48%) to the orthopedic department, 5 (6.4%) to neurosurgery and the remainder to a surgical department.

Results: Twenty-six patients (33.3%) received blood transfusion in the first 24 hours. Of the 25 patients (32%) with associated head trauma, 6 had intracranial bleeding; 29 patients (37%) had associated chest trauma, 28 (35.9%) had associated abdominal trauma, 16 (20.5%) had vertebral fractures and 40 (51.2%) had associated limb fractures. Pelvic angiography was performed in 5 patients (6.4%), and computed tomography-angiography of the cervical arteries and chest was performed in 1 and 5 patients respectively. Overall, a CT scan was performed in 56 patients (71.8%), of whom 25 (32%) had a pelvic CT on admission. Injury Severity Score was 4–66 (median 20). Laparotomy was performed in 14 patients (18%), spinal fusion in 5 (6.4%), limb surgery in 16 (20.5%), cranial surgery in 4 (5.02%), pelvic surgery in 10 (12.8%), chest surgery in 3 (3.85%), and facial surgery in 2 patients (2.56%). Seven patients (9%) died during the course of treatment.

Conclusion: Pelvic fracture carries a high morbidity rate. Associated chest, abdomen and limb injuries are often encountered. A multidisciplinary approach is needed to improve survival and outcome in patients with pelvic fractures.

 Moyamoya disease is a cerebral vasculopathy characterized mainly by progressive narrowing of the major intracranial vessels. While more common and having a familial predilection in the Far East, it can also develop in association with some common hereditary diseases and can be acquired after environmental exposure. In the young its manifestations are the result of cerebral ischemia. Adults usually suffer from repeated incidents of intracerebral hemorrhage. Surgical revascularization of ischemic cerebral territories plays a major role in their treatment. We review the literature and present our series of three adult and five pediatric patients; these patients were diagnosed at our institution and treated with indirect revascularization techniques.

 Colorectal cancers develop as a consequence of genomic instability. Microsatellite instability is involved in the genesis of about 15% of sporadic colorectal cancers and in most hereditary non-polyposis cancers. High frequency MSI[1] has been associated with a favorable prognosis, however it is not clear whether this is because MSI-H[2] tumors are inherently less aggressive or because they are more sensitive to chemotherapy. Chemotherapy with a combination of 5-fluorouracil and leukovorin or levamizole has been the standard of care for high risk stage II and stage III CRC[3]; it is also used in stage IV CRC. Several in vitro studies have shown that colon cancer cell lines displaying MSI-H are less responsive to fluorouracil than microsatellite-stable cell lines. Human studies, all of them retrospective, yielded conflicting results. The selection of patients with CRC for 5-FU[4] treatment has been based so far on the stage of tumor rather than the biology of the tumor. Although surgical staging is highly predictive of survival, there are indications that the form of genomic instability within a patient’s colorectal tumor has clinical implications, with and without 5-FU treatment. This review suggests that patients with MSI-H colorectal tumors may not benefit from 5-FU-based chemotherapy and can avoid its potential side effects (nausea, diarrhea, stomatitis, dermatitis, alopecia, and neurologic symptoms) that occur in half the treated patients. If confirmed by future prospective randomized controlled studies, these findings would indicate that microsatellite-instability testing should be conducted routinely and the results used to direct rational adjuvant chemotherapy in colon cancer.

 Background: Hypercholesterolemia control status is lacking throughout the western world.

Objectives: To examine whether the treatment recommendations given to ischemic heart disease patients at hospital discharge are compatible with the guidelines of the Israeli Medical Societies and the U.S. National Cholesterol Education Program for coronary artery disease prevention; and to study the effects of brief educational sessions on the adherence of physicians with the guidelines.

Methods: We included consecutive IHD[1] patients admitted to four central hospitals in Israel between 1998 and 2000. The study was conducted in two phases. In phase 1, we reviewed discharge letters to document treatment recommendations given to each patient. In phase 2 we educated the practitioners by reviewing the Israeli Medical Societies and the NCEP[2] guidelines and the quality of their recommendations in phase 1, after which we reevaluated the discharge letters.

Results: The study included 2,994 patients: 627 in phase 1 and 2,367 in phase 2. Of the patients who needed cholesterol-lowering according to their low density lipoprotein levels, 37.4% were not prescribed such drugs at discharge (under-treatment group). This proportion was reduced by education to 26.6% (P < 0.001) in phase 2. Of the treated patients, 65.6% did not reach the target LDL[3] goal in phase 1 (under-dosage group) as compared to 60.2% in phase 2 (P = 0.23). In phase 2 there was an increase in the percent of patients reaching LDL levels <130 mg/day (69.3% vs. 63.8% of patients prescribed medication, P = 0.01), but the percent of patients reaching LDL levels <100 was not different in phase 2 after adjusting for age and gender (the odds ratio for reaching target LDL was 1.16, with 95% confidence interval of 0.95–1.43).

Conclusions: Physician recommendations to IHD patients discharged from hospital were suboptimal. We documented a high proportion of under-treated and under-dosage patients. Brief educational sessions have a beneficial effect on the usage of statins; however, additional effort in guideline implementations is needed.

 Background: Abdominoperineal resection entails the need for a permanent colostomy, which significantly reduces patient self-image and quality of life.

Objective: To investigate the effectiveness of preoperative chemoradiation in increasing the resectability rates of rectal cancer and increasing the anal sphincter preservation rate.

Methods: The study group included 66 patients aged 33–84 years with T2–T3 rectal carcinoma who were treated in our institute from 1997 to 2002 with preoperative chemoradiation followed by surgery 6 weeks later. All patients underwent preoperative transrectal endoscopic ultrasound for tumor staging and localization. The duration of follow-up was 25 months.

Results: Chemoradiation led to tumor downstaging in 61 patients (92.4%), all of whom underwent low anterior resection. Only 11.4% of this group needed a temporary (6 weeks) loop colostomy/ileostomy. None of the 16 patients with post-treatment T0 tumors had evidence of malignant cells on pathologic study. Five patients (7.6%) failed to respond to chemoradiation and underwent APR[1]. There were no major complications, such as leakage, and no deaths.

Conclusions: Neoadjuvant chemoradiation is an effective modality to downstage advanced rectal cancer, improving patient quality of life by significantly reducing the need for a terminal permanent colostomy, or even a temporary one.

 Background: The preferred conservative treatment for congenital idiopathic clubfoot deformity remains a controversial issue.


Objectives: To compare the outcomes of two groups of CICF[1] patients who underwent two different treatment protocols.

Methods: The study cohort included 72 infants treated in our hospital from August 1998 to December 2002. Group 1 comprised 40 infants (61 clubfeet) who were treated by a traditional method (a modification of the Kite and Lovell technique), and group 2 consisted of 32 infants (48 clubfeet) who were treated with the Ponseti technique. Both groups were similar in age, gender and severity of the deformity (Dimeglio scoring system)

Results: After an average follow-up of 54.9 months (range 44–68), 35 (57%) clubfeet in group 1 required surgical intervention and 27 (44%) clubfeet had a residual deformity at last follow-up. In the Ponseti group, 45 (94%) clubfeet were fully corrected at last follow-up (average 29.2 months, range 16–45) while 3 (6%) clubfeet had residual deformity and required surgery. Tendo-Achilles tenotomy was performed with no complications in 47 clubfeet (in group 2) at an average age of 2.4 months (range 2–4 months).

Conclusions: Even after a relatively short follow‑up period, our success rate with the Ponseti approach already appears to be significantly higher and to bear fewer complications than the traditional treatment, in agreement with the results published by other medical centers. We now endorse the Ponseti technique of conservative manipulative treatment for congenital idiopathic clubfoot in our department.

 Background: Minimal invasive surgery for parathyroidectomy has been introduced in the treatment of hyperparathyroidism.

Objective: To evaluate the contribution of the sestamibi-SPECT (MIBI) localization, cervical ultrasonography, and intraoperative rapid turbo intact parathormone assay in minimal invasive parathyroidectomy.

Methods: Between August 1999 and March 2004, 146 consecutive hyperthyroid patients were treated using the MIBI and ultrasound for preoperative localization and iPTH[1] measurements for intraoperative assessment.

Results: Parathyroid adenoma was detected in 106 patients, primary hyperplasia in 16, secondary hyperplasia in 16, tertiary hyperplasia in 5 and parathyroid carcinoma in 1 patient. Minimal invasive exploration of the neck was performed in 84 of the 106 patients (79.2%) with an adenoma, and in 17 of them this procedure was performed under local cervical block anesthesia in awake patients. Adenoma was correctly diagnosed by MIBI scan in 74% of the patients, and by ultrasound in 61%. The addition of ultrasonography to MIBI increased the accuracy of adenoma detection to 83%. In 2 of the 146 patients (1.4%) iPTH could not be significantly reduced during the initial surgical procedure. Minimal invasive surgery with minimal morbidity, and avoiding bilateral neck exploration, was achieved in 79.2% of patients with a primary solitary adenoma.

Highly active antiretroviral therapy has dramatically improved the quality of life and life expectancy of patients with human immunodeficiency virus. However, the prolonged use of HAART[1] leads to severe metabolic adverse events. Both HIV[2]infection and HAART can cause changes in lipid and glucose metabolism as well as elevation of blood pressure, promoting the development of atherosclerosis. Cardiovascular diseases have become a major cause of mortality among HIV-infected subjects who respond well to antiretroviral therapy. Nevertheless, a proper lifestyle and pharmacologic intervention can improve cardiovascular risk factors in the HIV-treated population and significantly reduce healthcare investments in the treatment of future cardiovascular complications in this population. In this review we summarize the current knowledge of CVD[3] prevention and treatment in HIV patients.

Background: Torsade de pointes is rarely associated with chronic amiodarone treatment, despite the effect of amiodarone on QT interval prolongation.

Objective: To identify risk factors and associated conditions that may cause TdP[1] in patients on chronic amiodarone treatment.

Methods: We reviewed the data of six consecutive patients on chronic amiodarone treatment who were admitted to the intensive cardiac care unit due to syncope and TdP.

Results: The patients’ median age was 73.5 years, and five were women. Concomitantly, loratadine was given to two patients and trazodone to one patient. Associated and attributing conditions to the development of TdP were hypokalemia in three patients, drug-induced bradycardia in one and reduced left ventricular function in four.

Conclusions: TdP associated with chronic amiodarone treatment may occur when amiodarone is co-administered with drugs that may potentially prolong QT interval. Additional risk factors for amiodarone-associated TdP include female gender, hypokalemia, reduced left ventricular function and bradycardia.
