Background: Pilonidal disease in the natal cleft is treated traditionally by a wide and deep excision of the affected area. There is growing awareness, however, to the advantages of minimally invasive surgeries.

Objectives: To compare the efficacy of wide excision operations and minimal trephine surgery in patients with primary pilonidal disease.

Methods: In this retrospective study we examined surgical and inpatient records of 2039 patients who underwent surgery for primary pilonidal disease in five private hospitals between 2009 and 2012. Most procedures were of lay-open, primary midline closure, and minimal surgery types. Pilonidal recurrence rates were evaluated in a subset of 1260 patients operated by 53 surgeons each performing one type of surgery, regardless of patient characteristics or disease severity.

Results: With a mean follow-up of 7.2 years, 81.5%, 85%, and 88% of patients were disease-free after minimally invasive surgery, wide excision with primary closure, and lay-open surgery, respectively, with no statistically significant difference in recurrence rates. Minimal surgeries were usually performed under local anesthesia and involved lower pain levels, less need for analgesics, and shorter hospital stays than wide excision operations, which were normally performed under general anesthesia. The use of drainage, antibiotics, or methylene blue had no effect on recurrence of pilonidal disease.

Conclusions: Minimally invasive surgeries have the advantage of reducing the extent of surgical injury and preserving patient’s quality of life. They should be the treatment of choice for primary pilonidal disease

Background: The single-breath diffusing capacity of the lungs (DLCO_SB) test measures the extent to which carbon monoxide (CO) passes from the lung air sacs into the blood. The accessible alveolar volume (VA_SB) is measured by inert gas during a 10-second period. The single-breath transfer coefficient of the lung for carbon monoxide (KCO_SB) is the DLCO_SB divided by VA_SB. Cystic fibrosis (CF) disease comprises progressive airway obstruction with bronchiectasis and parenchyma fibrosis. Yet, the KCO_SB appears insignificant in the assessment of pulmonary function in CF.

Objectives: To challenge the precision of normal KCO_SB in CF.

Methods: The authors collected pulmonary function tests (PFT) data from 74 confirmed CF patients (mean age 26 ± 10 years) with various levels of pulmonary disease severity. Tests included spirometry, DLCO_BP, and body plethysmography (_BP). Anatomical dead space was calculated by deducting anatomical dead space from total lung capacity TLC(_BP) to establish alveolar volume (VA_BP) and to determine KCO_BP. We also included individual data of arterial pCO₂ blood-gas level.  

Results: KCO_SB values were normal or higher in most patients, regardless of patient FEV1 value (R² = 0.2204; P < 0.02). In contrast, the measurements of KCO_BP were low corresponding with low FEV1 values, and negatively correlated with the elevation of trapped air and pCO₂ levels (R² = 0.1383; P = 0.0133, P > 0.05, respectively).

Conclusions: The 10- second perfusion time of the inert gas during DLCO_SB represent the communicative alveolar volume in CF patients with advanced pulmonary disease. The findings justify the use of DLCO_SB with the deterioration of FEV1 and elevation of pCO₂ levels.

 Background: Hemorrhagic radiation cystitis (HRC) is a significant clinical problem that occurs after pelvic radiation therapy and is often refractory.

Objectives: To evaluate the efficacy and safety of hyperbaric oxygen therapy (HBO) for HRC.

Methods: Daily 90 minute sessions of HBO at 2 ATM 100% oxygen were given to 32 HRC patients with American Society of Therapeutic Radiology and Oncology (ASTRO) grades 3-4 hematuria.

Results: The median age was 72.5 (48–88 years). The median time interval between radiation therapy and HBO was 4 years (1–26 years). The patients received a median of 30 HBO sessions (3–53). Hematuria resolved in 27 patients (84%) and persisted in 5. Cystectomy was required in two, and ileal-conduit and bilateral percutaneous nephrostomies were performed in one and two patients, respectively. With a median follow-up of 12 months (5–74 months), the hematuria cleared completely in 16 patients (59%) and mild hematuria requiring no further treatment recurred in 10 others. Another patient with ASTRO grade 4 hematuria needed bladder irrigation and blood transfusions. Complications included eardrum perforation in four patients and transient vertigo and mild hemoptysis in one case each. None of them required HBO discontinuation.

Conclusions: HBO controlled bleeding in 84% of the patients. A durable freedom from significant hematuria was achieved in 96% of the patients. HBO seems to be an effective and safe modality in patients with HRC.

Objectives: To evaluate the national Israeli experience with lung transplantation in patients with CF[1].

Methods: We reviewed the medical charts of all CF patients who underwent lung transplantation between January 1996 and June 2005 at the two Israeli centers that performed this procedure.

Results: Eighteen transplantations were performed in 17 patients. Mean patient age at transplantation was 25.3 ± 9.1 years, and mean duration of follow-up in survivors (n=14) was 37.2 months (range 1–113 months). The actuarial survival rate was 88% at 1 year and 74% at 5 years. Pulmonary function, expressed as percent of predicted normal forced expiratory volume in 1 sec, improved from 22.4 ± 8.1% to 76 ± 16.8% at one year after transplantation. Bronchiolitis obliterans syndrome was diagnosed in 5 patients (29%), of whom 2 died and 2 are currently candidates for retransplantation. Median time to onset of BOS[2] was 34.2 months (range 17–64 months).

Conclusion: In Israel, the early and intermediate-term results of lung transplantation for cystic fibrosis are encouraging. BOS remains a major complication that threatens long-term outcome.

Objective: To describe the experience of our CF[1] center in the management of CF pregnant woman from 1977 to 2004.

Methods: We analyzed 27 years of records (1977–2004) of the national CF registry of all CF women who wished to conceive and became pregnant.

Results: Eight CF women (mean age 24 ± 4.5 years) who wished to conceive had 11 pregnancies and delivered 12 neonates. The pregestational results of forced expiratory volume per 1 second varied significantly among patients (59 ± 23%), yet most (10/11) stayed stable throughout the pregnancy course. Maternal deterioration in CF condition occurred in only one mother, necessitating cesarean section. In 9 of the 11 pregnancies the women were pancreatic-insufficient. Of the 11 pregnancies, 2 CF women had diabetes mellitus and 3 developed gestational diabetes. One pregnancy occurred in a mother with a transplanted lung. Of the 12 neonates, 3 were preterm and one was born with esophageal atresia. No miscarriages, terminations or neonatal mortalities occurred. Although most of the CF mothers had FEV_1[2] below 55% before pregnancy, the maternal and neonatal outcome was favorable and lung function tests generally remained stable.

Conclusions: We conclude that pregnancy in CF is feasible with a positive maternal and neonatal outcome. Early participation of the CF physician in the wish of the CF woman to reproduce is required. The integration of an intensive multidisciplinary approach during pregnancy, which includes close follow-up of maternal and fetal condition by the various specialists, should ensure an optimal outcome.

Background: Pulmonary disease is the most frequent cause of morbidity and mortality in cystc fibrosis patients. New techniques such as non-invasive positive pressure ventilation have resulted in prolongation of life expectancy in CF[1] patients with end-stage lung disease.

Objectives: To determine the role of NIPPV[2] in CF patients awaiting lung transplantation.

Methods: Between 1996 and 2001 nine CF patients (5 females) with end-stage lung disease were treated with bi-level positive airway pressure ventilation in the "spontaneous" mode.

Results: The patients' mean age at initiation of BiPAP[3] was 15 years (range 13–40 years) and the mean duration of BiPAP usage was 8 months (range 3–16 months). Four patients underwent successful lung transplantation, three patients died while awaiting transplantation, and the remaining two are still on NIPPV while waiting for transplantation. Patients' body mass index increased significantly (P < 0.05) during BiPAP therapy (from 16.1 to 17.2 kg/m²). Blood pH, p_aCO₂, and bicarbonate improved significantly (from 7.31 to 7.38, 90.8 to 67.2 mmHg, and 48.9 to 40.3 mEq/L, respectively). Pulmonary function tests were not affected by BiPAP usage. The patients experienced a significant alleviation in morning headaches and improvement in quality of sleep (P < 0.003). There were no major complications during BiPAP usage.

Conclusions: We demonstrated that long-term NIPPV can stabilize and improve physiologic parameters such as ventilation, arterial blood gases and body mass index, as well as subjective symptoms such as sleep pattern, daily activity level, and morning headaches in CF patients with end-stage lung disease. Further prospectively controlled studies are needed to evaluate the potential of BiPAP therapy and its influence on morbidity and mortality in the post-lung transplantation period.

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.

Vasopressin is a potent endogenous vasoconstrictor that increases blood pressure and systemic vascular resistance. The administration of exogenous vasopressin during closed and open cardiopulmonary resuscitation in humans was shown to be more effective than optimal doses of epinephrine in several clinical studies. We summarize here the recent experimental and clinical data on the use of vasopressin in cardiopulmonary resuscitation and septic shock. As the use of vasopressin in human resuscitation is now in its early stages, it is expected that accumulated future experience will shed more light regarding the risk-benefit aspects of its use.

Background: Acute scrotal pain in children presents a major diagnostic and therapeutic challenge. Epididymitis has been considered uncommon in childhood. The clinical spectrum and therapeutic policy of the acute scrotum in children is continually being reassessed.

Objectives: To determine whether there has been an increase in the incidence of epididymitis in children and to advocate a more selective surgical approach to the acute scrotum.

Methods: We conducted a retrospective review of 65 children admitted to our department of pediatric surgery with the diagnosis of acute scrotum during a 5 year period.

Results: Of the 65 children admitted with the diagnosis of acute scrotum, epididymitis was diagnosed in 42 (64.6%). The remaining cases included torsion of the testis in 12 patients (18.5%), torsion of the appendix testis in 5 (7.7%), scrotal pain and minimal physical findings in 4 (6.1%), and scrotal hematoma and idiopathic scrotal edema in one patient each. Doppler ultrasound of the groin, color Doppler ultrasound of the testis and testicular nuclide scintigraphy (Tc-99m scan) examinations were performed on 49, 30 and 57 occasions, respectively; the Tc-99m scan was the most effective tool. All the patients with epididymitis were diagnosed before surgical intervention and were treated conservatively.

Conclusions: We observed an increasing frequency of epididymitis in children admitted with the diagnosis of acute scrotum.
