Background: The role of prostatic fossa radiation as salvage therapy in the setting of a rising prostate-specific antigen following radical prostatectomy is not well defined.

Objectives: To study the efficacy and safety of pelvic and prostatic fossa radiation therapy following radical prostatectomy for adenocarcinoma.

Methods: A retrospective review of 1,050 patient charts treated at the Sheba Medical Center for prostate cancer between 1990 and 2002 identified 48 patients who received post-prostatectomy pelvic and prostatic fossa radiotherapy for biochemical failure. Two patients were classified as T-1, T2A-9, T2B-19, T3A-7 and T3B-11. Gleason score was 2–4 in 9 patients, 5–6 in 22 patients, 7 in 10 patients and 8–10 in 7 patients. Positive surgical margins were noted in 28 patients (58%) of whom 18 had single and 10 had multiple positive margins. Radiation was delivered with 6 mV photons using a four-field box to the pelvis followed by two lateral arcs to the prostatic fossa.

Results: At a median follow-up of 34.3 months (25th, 75th) (14.7, 51,3) since radiation therapy, 32 patients (66%) are free of disease or biochemical failure. Exploratory analysis revealed that a pre-radiation PSA[1] less than 2 ng/ml was associated with a failure rate of 24% compared with 66% in patients with a pre-radiation PSA greater than 2 ng/ml (chi-square P < 0.006).

Conclusions: For patients with biochemical failure following radical prostatectomy early salvage radiation therapy is an effective and safe treatment option.

Background: Although the home is perceived to be a safe haven, it is a scene of numerous injuries.

Objectives: To characterize home injury in Israel, the victims, injury circumstances and outcomes, and to identify groups at high risk for injury in order to focus future interventions and thus effectively prevent these injuries and their associated hospitalizations.

Methods: We analyzed 5 year records (1997–2001) from the National Trauma Registry of all patients arriving at eight trauma centers following home injury and admitted to hospital, transferred to another medical center or died in the emergency department.

Results: The study group included 26,921 patients, constituting 34% of all unintentional hospitalized trauma patients. Twenty-seven percent were children (0–4 years) and 37% were elderly (≥ 65 years) – the two age groups whose home injury accounted for most of the trauma injuries. Among children more boys (59%) than girls (41%) were injured, but the opposite was true for the elderly (30% males and 70% females). The share of females among the home-injured increased with age. Falls caused 79% of all home injuries (97% among the elderly) and burns 9%, increasing to 18% among children (0–4 years). Among non-Jewish home-injured patients, infants predominated (50% compared to 20% among Jews). Moderate to critical injuries amounted for 42%, with 38% of the home injured and 60% of the elderly requiring surgery. The clinical and economic consequences of home injuries differed according to the type of injury, with burns carrying the heaviest toll of prolonged intensive care and hospital stay. Overall, hospital stay averaged 6.2 days per patient (median 3 days).

Conclusions: Falls among the elderly, burns among children, and a high prevalence of hospitalization among non-Jewish children define groups at high risk for home injuries. Prevention programs should be based on these findings and should focus on the more vulnerable groups.

Background: Laryngeal obstruction due to bilateral vocal cord immobility in adduction may cause dyspnea, hoarseness and dysphagia and can lead to dependence on a tracheostomy. Treatment poses a challenge because of the opposing functions of the larynx and the risk of neck and laryngeal tissue damage.

Objectives: To describe our experience with endoscopic CO₂-laser-assisted posterior ventriculocordectomy without tracheostomy for the treatment of bilateral vocal cord immobility in adduction.

Method: The study group consisted of five male and five female patients aged 17–81 years. The procedure was performed with an endoscope and operating microscope connected to a CO₂ laser. A C-shaped incision was made, and the posterior third of one vocal cord, the vocal process of the arytenoid, and the posterior third of the false vocal cord were excised. Tracheostomy was not performed.

Results: The technique allowed for a convenient approach to the difficult-to-view areas of the larynx. The procedure was short and bloodless, with minimal damage to laryngeal tissue and no local edema. Hospitalization time was short. Postoperatively, patients had sufficient breathing and mostly fair to good voice quality. None of the patients had severe aspirations and only three patients had mild aspirations.

Conclusions: We recommend this procedure for patients with bilateral vocal cord immobility prior to tracheostomy. Delaying surgery beyond the time of possible re-innervation may place the patient at risk of decompensation, which requires tracheostomy.

Background: Contralateral exploration of the groin has been common practice among pediatric surgeons for nearly 50 years, based on the high incidence of patent processus vaginalis on the contralateral side with the potential for the subsequent development of a hernia.

Objectives: To evaluate transinguinal laparoscopic examination of the contralateral side during repair of inguinal hernia in children in order to reach a decision regarding exploration of the contralateral side.

Methods: Over a of 21 month period 124 children with unilateral inguinal hernia underwent laparoscopic evaluation of the contralateral groin. The operations were performed under general anesthesia as ambulatory procedures.

Results: Transinguinal contralateral laparoscopic exploration was positive (patent processus vaginalis) in 26 children (21%) and negative (closed processus vaginalis) in 88 (71%). Failure to introduce the telescope occurred in 10 patients (8%) due to a friable or narrow hernia sac. Twenty-five children below 2 years of age were spared exploration of the contralateral side as a result of the negative laparoscopic examination. On the other hand, 15 children aged 2–17 had their contralateral groin explored because of a positive finding at laparoscopy.

Conclusions: Transinguinal laparoscopic examination of the contralateral side during repair of inguinal hernia in children is a simple, safe and quick method to avoid systematic bilateral explorations and should be part of every pediatric surgeon's experience.

Background: The external approach is the golden standard for sinonasal tumor removal but it is associated with several side effects, including facial scars, intracranial and extracranial complications, a long hospitalization period and high costs. Endoscopic sinus surgery enables resection of benign and selected malignant sinonasal tumors and has the advantages of no facial scars, better functional and structural preservation of the sinonasal complex, minimal trauma to surrounding tissue, a shorter hospitalization stay and lower costs.

Objectives: To evaluate the advantages and limitations of endoscopic resection of benign and malignant sinonasal tumors, their recurrence and complication rates.

Methods: The medical and radiology records of 56 patients who underwent endonasal endoscopic resection of benign and malignant sinonasal tumors between 1996 and 2003 were retrospectively reviewed. Tumors located in the center of the nose and sinuses were endoscopically resected.

Results: Six cases of malignant tumor and 50 cases of benign tumor underwent resection by ESS[1]. One of the patients with malignant tumor died, the remainder showing no evidence of disease on follow-up of 3–60 months (mean 26.8 months). Inverted papilloma was the most common benign tumor (40 patients). Seven patients (18%) had recurrence followed by endonasal resection. No major complications were recorded. Hospitalization stay was 2–7 days (mean 3.6 days).

Conclusions: Endoscopic resection of benign sinonasal tumors that are centrally located in the nose and sinuses should be considered before the external approach is used. In very carefully selected cases of malignant tumors ESS is oncologically acceptable, but more experience is needed for discerning the indications for endoscopic resection of malignant tumors. The complication rate for endoscopic resection is low, there are no facial scars, hospitalization stay is short, and costs are low.

The treatment of acute pain and anxiety in children undergoing therapeutic and diagnostic procedures in the emergency department has improved dramatically in recent years. The availability of non-invasive monitoring devices and the use of short-acting sedative and analgesic medications enable physicians to conduct safe and effective sedation and analgesia treatment. In today's practice of pediatric emergency medicine, sedation and analgesia has been considered as the standard of care for procedural pain. In most pediatric emergency departments throughout North America, "procedural sedation and analgesia" treatment is being performed by non-anesthesiologists (qualified emergency physicians and nurses). In 2003, the Israel Ministry of Health published formal guidelines for pediatric sedation by non-anesthesiologists; this important document recognizes for the first time the need for pediatric sedation and analgesia in the operating room. We describe the basic principles of procedural sedation and analgesia in children and urge physicians working in pediatric emergency rooms in Israel to expand their knowledge and be more involved in the treatment of pediatric procedural pain.
