Background: The contribution of drugs and alcohol to current trauma‑related morbidity and mortality in Israel is not known. Identification of these factors in the fast-changing demographics of the Israeli population might lead to better care and, no less importantly, to targeted prevention measures.

Objectives: To determine the incidence of alcohol‑related trauma, and to specify the time of day, the cause of trauma, and the morbidity and mortality rates as compared to non-alcohol‑associated trauma in the tertiary trauma unit of a large medical center in Tel Aviv.

Methods: Data were obtained from the Israel National Trauma Registry, based on patient records in our institution (Tel Aviv Sourasky Medical Center) from January 2001 to December 2003.

Results: Of the 5,529 patients who were enrolled in the study, 170 had high alcohol blood levels (> 50 mg/dl). Patients intoxicated with alcohol had higher rates of road accident injuries (35% versus 24% non‑intoxicated) and stab wounds (29% vs. 7%). The Injury Severity Score of the alcohol‑intoxicated patients was higher (32% ³ 16 vs. 12% ³ 16). The alcohol‑intoxicated patients were more likely to be non-Jewish (34% vs. 9%), young (82% aged 15–44 years) and males (91%). Most of the alcohol‑related injuries occurred during the weekend (47%) and during evening‑late night hours (from 7 a.m. to 11 p.m.; 55%).

Conclusions: Alcohol‑associated trauma differs from non-alcohol‑associated trauma in many ways. Since the population at risk can be identified, it is important that legislative, social, enforcement and educational measures be adopted to reduce the extent of alcohol abuse and thereby improve the level of public safety.
 

Background: Preoperative radiotherapy is standard treatment for rectal cancer and is often combined with 5-fluorouracil-based chemotherapy. UFT, a new oral 5FU[1] derivative, given daily during a course of radiotherapy mimics the effect of continuous-infusion 5FU.

Objectives: To determine the maximum tolerated dose of oral UFT and leucovorin with preoperative pelvic irradiation for rectal cancer, and assess tumor response.

Methods: In this phase 1 trial, 16 patients aged 42–79 years with tumors within 12 cm of the anal verge received radiotherapy, 45 Gy over 5 weeks, an escalating dose of oral UFT, and a fixed dose of 30 mg/day leucovorin. UFT and leucovorin were given for 28 consecutive days concomitant with the first 4 weeks of radiotherapy. Surgery was scheduled for 4–6 weeks after completion of radiotherapy. The surgical procedure was determined by the surgeon at the time of surgery.

Results: No grade III toxicity was seen at 200 mg/m²/day UFT. Of eight patients who received 240 mg/m²/day UFT, one developed grade IV diarrhea; of four patients who received 270 mg/m²/day UFT, one was hospitalized with grade IV diarrhea and leukopenic fever and died during hospitalization. Of the 15 evaluable patients, 9 had pathologic tumor down-staging including 4 patients with complete response. Only one patient required a colostomy.
Conclusions: The MTD[2] of UFT together with leucovorin and preoperative radiotherapy for rectal cancer is 240 mg/m². The major toxicity was diarrhea. Down-staging was noted in 60% of patients, allowing sphincter-preserving surgery even in patients with low tumors.

Background: Primary hyperparathyroidism in elderly patients is usually associated with additional co-morbidity that increases operative risk, and thus many geriatric patients are denied the benefit of surgery for a single parathyroid adenoma.

Objectives:  To evaluate the safety and efficacy of accurate single photon emission computed tomography sestamibi scintigraphy, enabling precise localization of a single adenoma, in the geriatric population

Methods: Twenty-two patients aged 70 years and over with biochemically proven PHPT[1] and with a single parathyroid adenoma identified by localization studies (sestamibi SPECT[2] scan and ultrasonography) underwent 23 operations over 29 months (out of a total of 140 patients operated upon during the same period). Immediate preoperative sestamibi scintigraphy and marking of focal adenoma uptake followed by intraoperative hand-held gamma probe were used for the removal of the parathyroid adenoma by unilateral minimal access surgery. Associated major co-morbid conditions and pre- and postoperative calcium, phosphorus and parathormone levels were recorded. Indications for surgery were listed and operative and postoperative complications were noted. The patients were followed for a mean period of 17.7 months using the same parameters.

Results: The 22 patients with PHPT had a mean age of 76.3 ± 5.9 years (range 70–88 years)  and a female to male ratio of 13:9. Associated co-morbidity included ischemic heart disease (n=15), hypertension (n=22), non-insulin-dependent diabetes mellitus (n=9), chronic obstructive pulmonary disease (n=3), and previous neck surgery (n=3). Mean preoperative serum calcium, phosphorous and PTH[3] were 11.7 ± 1.3 mg/dl, 2.5 ± 0.5 mg/dl and 160.9 ± 75.4 pg/ml respectively. In 20 of the 22 patients, surgery was successful in curing PHPT (91%). One patient had persistent hypercalcemia due to a missed adenoma, and repeat operation (by focused minimal access surgery) was successfully performed 2 weeks later. There were no complications and no morbidity postoperatively. Mean postoperative serum calcium, phosphorous and PTH were 9.6 ± 1.2 mg/dl, 3.0 ± 0.5 mg/dl and 35.2 ± 24 pg/ml respectively. In all patients, serum calcium levels remained normal (9.7 ± 1.3 mg/ml) after long-term follow-up (mean 17.7 ± 9.6 months).

Conclusions: Minimally invasive, radio-guided focused parathyroidectomy for a single adenoma is a safe and effective method to cure hyperparathyroidism in the elderly. Success of surgery is directly related to the surgeon's experience and to the precise localization marking provided by sestamibi scintigraphic SPECT localization and concurrent sonographic findings.

Background: Congenital subependymal pseudocysts are incidental findings that are found in 05-5.2% of neonates during postmortem examination or head ultrasonography. In our institution we detected 10 neonates with CSEPC.

Objective: To investigate associated etiological factors, morphologic characteristics and outcome of CSEPC.

Methods: We performed a meta-analysis of the literature on CSEPC (1967-98), including our 10 cases.

Results: A total of 256 cases of CSEPC were analyzed. Ultrasound diagnosed 77.6% of CSEPC 48.8% were bilateral and 53.4% were located in the caudothalamic groove or head of caudate nucleus. Altogether, 93.5% resolved during 1-12 months of ultrasonographic follow-up. Compared to the general neonatal population, the following features were more prevalent in the CSEPC population: prematurity, maternal vaginal bleeding, preeclamptic toxemia, intrauterine growth restriction, asphyxia, fetal cytomegalovirus and rubella infec­tions, congenital malformations, chromosomal aberrations, infant mortality, and neurodevelopmental handicap. The risk for neurodevelopmental handicap was significantly higher when CSEPC were associated with fetal infections, IUGR, malformations and chromosomal aberrations, or persistence of CSEPC during follow-up. CSEPC infants without any of these four conditions had a low risk for neurodevelopmental handi­cap.

Conclusions: CSEPC are morphologic features of various underlying conditions encountered in the fetus. Association of CSEPC with IUGR, fetal infections, malformations and chromosomal aberrations or persistence of CSEPC indicates a higher risk for future neurodevelopmental handicaps, probably because of the deleterious effects on the fetal brain that are inherent in these conditions. A favorable outcome is expected in the absence of these risk factors.
