Hiatal hernia is defined as a protrusion of abdominal contents through the hiatal foramen into the thoracic cavity. Etiology is presumed to be a congenital malformation, trauma, or iatrogenic like prior surgical dissection of the hiatus during surgery for esophageal or gastric etiology. Age, sex, hormonal changes, body habitus (i.e., kyphosis, scoliosis), and increased body weight are key risk factors. Most hiatal hernias are asymptomatic and discovered incidentally. Surgical repair of hiatal hernia is indicated in symptomatic patients with dysphagia, weight loss, respiratory symptoms such as aspirations, and recurrent pneumonia events [1]. Complications arising from laparoscopic repair of hiatal hernia are generally minor and do not typically necessitate surgical intervention. Major complications include pneumothorax, splenic laceration, esophageal rupture, and pericardial injury. Other complications include recurrence of hernia, vagal nerve injury, gastroesophageal reflux disease, and gastroparesis. The utilization of mesh in repair procedures introduces additional complications such as mesh migration and mesh infection. Previously reported recurrence rates following the repair of a hiatal hernia with mesh range from 10–30%. In this case communications, we presented a case involving the early recognition and treatment of postoperative cardiac tamponade.

Background: Asthma is a common respiratory disease, which is linked to air pollution. However, little is known about the effect of specific air pollution sources on asthma occurrence.

Objective: To assess individual asthma risk in three urban areas in Israel characterized by different primary sources of air pollution: predominantly traffic-related air pollution (Tel Aviv) or predominantly industrial air pollution (Haifa bay area and Hadera). 

Methods: The medical records of 13,875, 16- 19-year-old males, who lived in the affected urban areas prior to their army recruitment and who underwent standard pre-military health examinations during 2012–2014, were examined. Nonparametric tests were applied to compare asthma prevalence, and binary logistic regressions were used to assess the asthma risk attributed to the residential locations of the subjects, controlling for confounders, such as socio-demographic status, body mass index, cognitive abilities, and education.

Results: The asthma rate among young males residing in Tel Aviv was 8.76%, compared to 6.96% in the Haifa bay area and 6.09% in Hadera. However, no statistically significant differences in asthma risk among the three urban areas was found in controlled logistic regressions (P > 0.20). This finding indicates that exposure to both industrial- and traffic-related air pollution is associated with asthma prevalence.

Conclusions: Both industrial- and traffic-related air pollution have a negative effect on asthma risk in young males. Studies evaluating the association between asthma risk and specific air pollutants (e.g., sulfur dioxide, particulate matter, and nitrogen dioxide) are needed to ascertain the effects of individual air pollutants on asthma occurrence.

Background: Fecal incontinence is defined as involuntary passage of stool through the anus. It may vary from soiling to complete evacuation. This involuntary loss of feces, flatus or urge incontinence adversely affects quality of life. Urinary urge incontinence is characterized by symptoms of frequency, urgency and urge incontinence (either alone or in combination). Urgency frequency syndrome is defined as symptoms of frequency and urgency without incontinence episodes.

Objectives: To evaluate the efficacy of sacral neuromodulation on these pathologies. 

Methods: Following a detailed investigation, 51 patients with either urinary or fecal incontinence, or both, who did not respond to medical and behavioral treatment were offered the temporary implant. Of the 51 patients 40 showed improvement and advanced for a permanent device.

Results: After a mean follow-up of 5 years (range 1–8), there was a significant reduction in the number of incontinence episodes (P < 0.0001), and the number of pads used also declined significantly (P < 0.0001). A marked improvement in quality of life was reported by 71.4% of the women and 58.3% of the men.

Conclusions: Sacral neuromodulation as shown in this study appears to be a promising treatment for urinary and fecal incontinence and can dramatically improve patients' quality of life.

 Background: The Israeli Board of Anesthesiology Examination Committee added a simulation-based Objective Structured Clinical Evaluation (OSCE) component to the board examination process. This addition was made in order to evaluate medical competence and considers certain domains that contribute to professionalism. This unique and new process was in a need to be validated.

Objectives: To validate and evaluate the reliability and realism of incorporating simulation-based OSCE into the Israeli Board Examination in Anesthesia.

Methods: Validation was performed before the exam regarding Content Validity using the modified Delphi technique by members of the Task Force of the Israeli Board Examination Committee in Anesthesiology.

Results: The examination has been administered six times in the past 3 years to a total of 145 examinees. The pass rate ranged from 62% (trauma) to 91% (regional anesthesia). The mean inter-rater correlations for the total score (all items), for the Critical checklist items score, and for the Global (General) rating were 0.89, 0.86 and 0.76, respectively. The inter-correlations between the five OSCE stations scores were significant (P < 0.01) only between Trauma & Ventilation for the Total score (r = 0.32, n=63), and between Resuscitation & Regional and OR-crisis for the Global score (r = 0.42 and 0.27, n=64 and 104, respectively). The correlation between the OSCE examination score and the success rate at each of the eight different clinical domains of the oral board examination did not reach statistical significance. Most participants (70–90%) found the difficulty level of the examination stations reasonable to very easy. All major errors, which were identified in the initial two exam periods, disappeared later in the next two exam periods.

Conclusions: The exam has gradually progressed from being an optional part of the oral board examination to a prerequisite component of this test. Other anesthesiology programs or medical professions can adopt the model described here.

Background: Lipoid pneumonia is a pneumonitis resulting from the aspiration of lipids, and is commonly associated with the use of mineral oil as a laxative. LP[1] is relatively unfamiliar to clinicians and is probably underdiagnosed.

Objectives: To increase physicians' awareness of LP, its diagnosis and prevention.

Methods: We present two illustrative cases of LP and review the literature.

Results: Two cases of LP were diagnosed within half a year in an internal medicine ward. Both cases were elderly patients, and LP was associated with the use of mineral oil as a laxative agent. Computerized tomography revealed bilateral low attenuation infiltrates, associated with a "crazy paving" pattern in one case. Sudan Black staining was diagnostic in both cases – in one on a transbronchial biopsy specimen, and in the other on sputum cytologic examination. Both patients suffered from neurologic diseases and were at risk of aspiration. In both cases clinical symptoms and signs continued for several months prior to diagnosis but resolved after the mineral oil was discontinued.

Conclusions: LP often occurs in elderly patients who are at risk of aspiration. The condition may be underdiagnosed. Since in most cases mineral oil cathartics are the causative agent, an effort at primary prevention is indicated. It is suggested that the licensing of mineral oil for internal use be changed.

Background: The precise genes involved in conferring prostate cancer risk in sporadic and familial cases are not fully known.

Objectives: To evlauate the genetic profile within several candidate genes of unselected prostate cancer cases and to correlate this profile with disease parameters.

Methods: Jewish Israeli prostate cancer patients (n=224) were genotyped for polymorphisms within candidate genes: p53, ER, VDR, GSTT1, CYP1A1, GSTP1, GSTM1, EPHX and HPC2/ELAC2, followed by analysis of the genotype with relevant clinical and pathologic parameters.

Results: The EPHX gene His113 allele was detected in 21.4% (33/154) of patients in whom disease was diagnosed above 61 years, compared with 5.7% (4/70) in earlier onset disease (P < 0.001). Within the group of late-onset disease, the same allele was noted in 5.5% (2/36) with grade I tumors compared with 18% (34/188) with grade II and up (P = 0.004). All other tested polymorphisms were not associated with a distinct clinical or pathologic feature in a statistically significant manner.

Conclusions: In Israeli prostate cancer patients, the EPHX His113 allele is seemingly associated with a more advanced, late-onset disease. These preliminary data need to be confirmed by a larger and more ethnically diverse study.

Background: Cystinuria is an autosomal recessive disease that is manifested by the development of kidney stones. Mutations in SLC3A1 cause type I disease, while mutations in SLC7A9 are associated with non-type I disease. In Israel cystinuria is especially common among Libyan Jews who suffer from non-type I disease.

Objectives: To compare clinical manifestations of patients with mutations in SLC3A1 to those with mutations in SLC7A9, and to assess the carrier rate among unaffected Libyan Jewish controls.

Methods: Clinical manifestations were evaluated in patients with mutations in SLC3A1 and in patients with mutations in SLC7A9. Carrier rates for two SLC7A9 mutations were assessed in 287 unaffected Libyan Jewish controls.

Results: Twelve patients with mutations in SLC3A1 were compared to 15 patients with mutations in SLC7A9. No differences were detected between the patients with mutations in SLC3A1 and those with mutations in SLC7A9 in relation to the age of disease onset, the estimated number of stones, the number of invasive procedures, the number of patients receiving drug therapy, or the patients’ urinary pH. Eleven of the unaffected Libyan Jewish controls were found heterozygotes for the V170M mutation, establishing a carrier rate of 1:25. The 1584+3 del AAGT mutation was not found in any of the Libyan Jewish controls.

Conclusion: Mutations in SLC3A1 and SLC7A9 cystinuria patients result in indistinguishable disease manifestations. The high carrier rate among Libyan Jews is a result of a single missense mutation, V170M.
