Background: A dental appliance for obstructive sleep apnea (OSA) is recommended for patients who cannot adjust to continuous positive airway pressure (CPAP) treatments.



Objectives: To describe patients with extremely severe OSA who were successfully treated with a dental appliance and to compare their characteristics with the relevant literature to identify clinical features associated with a good outcome.



Methods: The clinical, management, and outcome data of three patients with an apnea-hypopnea index (AHI) of > 80 who showed clinical improvement following treatment with a dental appliance were collected retrospectively from sleep laboratory reports in Israel over a period of 3 years. 



Results: The patients included one man and two women, aged 33, 56, and 61 years, respectively. The diagnosis of OSA was based on clinical examination and polysomnography. AHI values at presentation were 83, 81, and 84, respectively. Treatment with a dental appliance (Herbst® or MDSA®) was proposed due to patient noncompliance with CPAP. Follow-up polysomnography with the dental appliance revealed a reduction in the AHI to 1.7, 10.7, and 11, respectively. All patients had supine OSA and a retrognathic mandible, both of which have been found to be associated with a good prognosis for treatment with a dental appliance.



Conclusions: Dental appliances may be considered an appropriate second-choice option to treat severe OSA in patients who are noncompliant with CPAP. This study helps physicians identify patients with extremely severe OSA who are suitable for dental appliance treatment. Well-designed large-scale studies are needed to reach definitive conclusions. 

Delusional parasitosis (DP) is a somatic type of delusional disorder, usually mono-symptomatic, in which the patients are convinced they are being infested with animal parasites while no objective evidence exists to support this belief. The complaints are usually about skin infestation, but involvement of the gastrointestinal tract has also been described. Numerous samples are brought for examination from skin, clothes, and environmental sources, while a detailed description of the “parasite” is given. In primary DP, the delusion arises spontaneously as a mono-delusional disorder, while in secondary DP, the delusional disorder arises secondary to another major medical, neurological, or psychiatric disorder. Practically all patients refuse psychiatric help. Shared psychotic disorder – folie à deux – is a known mode of presentation in delusional parasitosis. More than one member within a family may experience the same delusional state. For diagnosis and treatment of DP, a close collaboration among dermatologists, psychiatrists, and parasitologists is essential. Patients whose delusion of parasitosis is not severe can sometimes be relieved of their symptoms by establishing a reliable and meaningful therapeutic relationship. Symptomatic medication may be prescribed for the relief of pruritus, pain, and other symptoms. In more severe cases, such patients should be treated with psychopharmacological agents.

Background: The most common complication after tonsillectomy is bleeding. We investigated whether performing the procedure during the summer or the winter affects the bleeding rate.

Objectives: To investigate whether there is an association between meteorological conditions and the occurrence of post-tonsillectomy hemorrhage (PTH) in the southern Israel Negev region.

Methods: All patients who underwent tonsillectomy from 2001–2013 at the Soroka Medical Center were included. We collected patient demographic data and indications for surgery. Meteorological data were obtained from a weather station operated by the Israel Ministry of Environmental Protection.

Results: Of 4438 patients who underwent tonsillectomy, with or without adenoidectomy, 432 (9.73%) experienced hemorrhage. Patients who suffered from PTH were significantly older: median age 9.61 years vs.4.7 years, P < 0.0001. When comparing patients without PTH to those who bled within 0–3 days after surgery, there was a higher risk for bleeding during the warmer seasons: relative risk (RR) 1.38, 95% confidence interval ([95%CI] 1.07–1.77), RR 1.45 (95%CI 1.17–1.80), and 1.62 (95%CI 1.27–2.06) comparing the winter to spring, summer, and fall, respectively. A statistically significant positive association was also found with the average temperature on the day of surgery. Bleeding more than 3 days after surgery was less likely in summer: RR 0.82, 95%CI 0.69–0.97. We found no association with temperature on the day of surgery and PTH after postoperative day 3.

Conclusions: Seasonality, and to an extent temperature, seem to play only a minor role in PTH.

Background: Wandering spleen is a rare entity that may pose a surgical emergency following torsion of the splenic vessels, mainly because of a delayed diagnosis. Complications after surgery for wandering spleen may necessitate emergency treatment.

Objectives: To describe the clinical course and treatment for children who underwent emergency surgeries for wandering spleen at a tertiary pediatric medical center over a 21 year period and to indicate the pitfalls in diagnosis and treatment as reflected by our experience and in the literature.

Methods: The database of a tertiary pediatric medical center was searched retrospectively for all children who underwent emergency treatment for wandering spleen between 1996 and 2017. Data were collected from the medical files. The relevant literature was reviewed.

Results: Of ten patients who underwent surgery for wandering spleen during the study period, five underwent seven emergency surgeries. One patient underwent surgery immediately at initial presentation. In the other four, surgical treatment was delayed either due to misdiagnosis or for repeated imaging studies to confirm the diagnosis. Emergency laparotomy revealed an ischemic spleen in all patients; splenectomy was performed in two and the spleen was preserved in three. Four of the seven emergency operations were performed as the primary surgery and three were performed to treat complications.

Conclusions: Wandering spleen should ideally be treated on an elective or semi-elective basis. Surgical delays could be partially minimized by a high index of suspicion at diagnosis and by eliminating unnecessary and time-consuming repeated imaging studies.

Background: About half of all patients with heart failure are diagnosed with heart failure preserved ejection fraction (HFpEF). Until now, studies have failed to show that medical treatment improves the prognosis of patients with HFpEF.

Objectives: To evaluate changes in exercise capacity of patients with HFpEF compared to those with heart failure with reduced ejection fraction (HFrEF) following an exercise training program.

Methods: Patient data was retrieved from a multi-center registry of patients with heart failure who participated in a cardiac rehabilitation program. Patients underwent exercise testing and an echocardiogram prior to entering the program and were retested6  months later.

Results: Of 216 heart failure patients enrolled in the program, 170 were diagnosed with HFrEF and 46 (21%) with HFpEF. Patients with HFpEF had lower baseline exercise capacity compared to those with HFrEF. Participating in a 6 month exercise program resulted in significant and similar improvement in exercise performance of both HFpEF and HFrEF patients: an absolute metabolic equivalent (MET) change (1.45 METs in HFrEF patients vs. 1.1 in the HFpEF group, P = 0.3).

Conclusions: An exercise training program resulted in similar improvement of exercise capacity in both HFpEF and HFrEF patients. An individualized, yet similarly structured, cardiac rehabilitation program may serve both heart failure groups, providing safety and efficacy.

Background: The treatment of advanced dementia patients is very complex and presents a difficult dilemma for physicians, and especially for the patient's family. In many cases, when the advanced dementia patient has no decisional capacity, the family needs to decide about force-feeding and resuscitation for their relative.

Objectives: To examine public opinion regarding force-feeding and resuscitation of patients with advanced dementia.

Methods: Data from 1002 people who accompanied a patient to a hospital emergency department in Israel were collected and analyzed.

Results: We noted the following results: the more religious the orientation of the respondents, the more likely they were to agree to forcefully feed and resuscitate advanced dementia patients and advanced dementia patients older than 80 years; those accompanying younger patients were more likely to think that the medical staff should resuscitate advanced dementia patients and advanced dementia patients older than 80 years compared to those accompanying elderly patients; younger people were more likely than older people to agree to force-feed and resuscitate patients.

Conclusions: This paper attempts to provide decision-makers and medical staff with some knowledge about public opinion regarding a sensitive and complex issue. This awareness may guide physicians in making critical medical decisions about those with dementia.

Background: Vitamin D deficiency and insufficiency have been reported in fibromyalgia. However, to the best of our knowledge, only one study has evaluated the role of 25-hydroxyvitamin D [25(OH)D] supplementation on fibromyalgia symptoms.

Objectives: To analyze the effects of 3 months of 25(OH)D supplementation on symptoms of fibromyalgia.

Methods: This study included 11 female patient. Demographic and clinical data, tender points, visual analog scale results, and pre- and post-serum levels of 25(OH)D supplementation were analyzed. The levels of 25(OH)D were measured by a radioimmunologic test.

Results: Patients with fibromyalgia diagnosis and 25(OH)D values ≤ 30 ng/ml were recruited to receive 50,000 IU of oral vitamin D once every week for 3 months. The disease was diagnosed based on the American College of Rheumatology criteria. The median age of all patients was 48.5 (28–67) years and 63.4% were Caucasian. Disease duration varied from 1–10 years. The 25(OH)D levels increased significantly after 3 months, 18.4 (15.5–25.8) ng/ml vs. 33.8 (28–58) ng/ml, P = 0.01. Interestingly, an improvement of visual analog scale scores was observed at 3 months, 90 (0–100) vs. 30 (0–80), P = 0.002. Eight patients (72.2%) responded that they experienced a very significant improvement in symptoms. In addition, a trend for reduction of the number of tender points was observed after 3 months, 17 (11–18) vs. 10 (0–18), P = 0.07.

Conclusions: The 25(OH)D levels and disease symptoms in patients with fibromyalgia and vitamin D deficiency/insufficiency seem to improve with vitamin D supplementation.

Background: Limited information exists about detailed clinical characteristics and management of the small subset of Brugada syndrome (BrS) patients who had an arrhythmic event (AE).

Objectives: To conduct the first nationwide survey focused on BrS patients with documented AE.

Methods: Israeli electrophysiology units participated if they had treated BrS patients who had cardiac arrest (CA) (lethal/aborted; group 1) or experienced appropriate therapy for tachyarrhythmias after prophylactic implantable cardioverter defibrillator (ICD) implantation (group 2).

Results: The cohort comprised 31 patients: 25 in group 1, 6 in group 2. Group 1: 96% male, mean CA age 38 years (range 13–84). Nine patients (36%) presented with arrhythmic storm and three had a lethal outcome; 17 (68%) had spontaneous type 1 Brugada electrocardiography (ECG). An electrophysiology study (EPS) was performed on 11 patients with inducible ventricular fibrillation (VF) in 10, which was prevented by quinidine in 9/10 patients. During follow-up (143 ± 119 months) eight patients experienced appropriate shocks, none while on quinidine. Group 2: all male, age 30–53 years; 4/6 patients had familial history of sudden death age < 50 years. Five patients had spontaneous type 1 Brugada ECG and four were asymptomatic at ICD implantation. EPS was performed in four patients with inducible VF in three. During long-term follow-up, five patients received ≥ 1 appropriate shocks, one had ATP for sustained VT (none taking quinidine). No AE recurred in patients subsequently treated with quinidine.

Conclusions: CA from BrS is apparently a rare occurrence on a national scale and no AE occurred in any patient treated with quinidine.

Background: Acute musculoskeletal pain is one of the most commonly reported symptoms among patients visiting the emergency department (ED). Treatment with over-the-counter pain medications, given by nurses, results in improved pain management and reduces the waiting time to drug administration without significant side effects. Opioid analgesics are extensively used for acute pain in the ED. Compared to morphine, oxycodone has a much more specific pharmacological activity, higher analgesic potential, and more tolerable side effects.

Objectives: To assess the degree of pain reduction using different protocols, including dypirone and oxycodone given by nurses, in treating acute musculoskeletal pain in the emergency department (primary outcome) and to evaluate the need for rescue medications (secondary outcome).

Methods: This observational prospective clinical trial compared two groups of 50 patients, each one visiting the ED due to musculoskeletal pain. One group was treated with dipyrone syrup and the other was treated with oxycodone syrup. The primary outcome was pain reduction measured by the Numeric Rating Scale (NRS). The secondary outcome was the difference in need for rescue medications.

Results: The reduction in the NRS was greater in the patients treated with oxycodone. This finding was statistically and clinically significant (P < 0.001). The need for rescue medications was also significantly reduced in this group of patients (P = 0.007).

Conclusions: This study showed that the administration of over-the-counter oxycodone syrup by nurses decreases the post-treatment pain reported by patients, reduces the need for rescue medications, and increases the satisfaction of the medical staff.

Background: The recommendation of the U.S. Centers for Disease Control and Prevention regarding universal screening for Group B Streptococcus (GBS) at 35–37 weeks gestational age in pregnancy is not accepted in Israel. The National Council for Obstetrics, Neonatology and Genetics recommends intrapartum prophylaxis, mainly based on risk factors, to prevent early neonatal GBS infection. This policy is based on past studies demonstrating low colonization rates of the bacteria in Israeli pregnant women and very low neonatal sepsis rates.

Objectives: To determine the applicability of the high-risk group prophylaxis policy for Arab Israeli pregnant women.

Methods: Vaginorectal swabs from Arab Israeli pregnant women who attended the labor ward between October 2015 and February 2016, were obtained before any pelvic examination for GBS identification using Quidel’s AmpliVue® GBS assay. Women who tested positive received intrapartum antibiotic prophylaxis to prevent neonatal infection. Obstetric data were collected from each woman from a standardized questionnaire. Data regarding the delivery and neonates were collected as well.

Results: The study comprised 188 Arab pregnant women who met the inclusion criteria and signed a consent form to participate in the study. Of these, 59 had positive tests, and a carriage rate of 31%. No neonatal colonization of GBS was found.

Conclusions: The carrier rate in Arab pregnant women in northern Israel is higher than the national average, at least partially due to the more sensitive method of GBS detection used in the present study.

Background: Damage control laparotomy (DCL) is the widely accepted procedure of choice in management of severely injured trauma patient. It has been implemented in non-trauma-related surgical pathology in the last decade.

Objectives: To evaluate our experience with planned re-laparotomy (PRL) in non-trauma patients and compare it to other reports.

Methods: Charts of all patients admitted to Assaf Harofeh Medical Center who underwent PRL for non-trauma-related abdominal pathology during a 6 year period were reviewed. Data regarding demographics, vital signs, laboratory tests, indications for surgery, length of hospital stay, and mortality were obtained from medical charts. Indications for surgery, risk factors, and mortality were analyzed.

Results: The study was comprised of 181 patients. Primary abdominal sepsis (50), postoperative sepsis (49), mesenteric event (32), and intestinal obstruction (28) were the most common indications for PRL. Mortality rate was 48.6%. Factors correlating with increased mortality were advanced age, hypotension, hypothermia, metabolic acidosis, and renal failure. Bowel resection was performed on 122 patients (67%) and primary intestinal anastomosis constructed in 46.7%. Mortality rate was lower in patients who underwent PRL with primary anastomosis compared to patients with postponed bowel anastomosis (33.3% vs. 55.4%, P = 0.018).

Conclusions: PRL in abdominal emergencies carries a high mortality rate. Primary anastomosis may be considered in non-trauma-related PRL.

Background: When a patient arrives at the emergency department (ED) presenting with symptoms of acute decompensated heart failure (ADHF), it is possible to reach a definitive diagnosis through many different venues, including medical history, physical examination, echocardiography, chest X-ray, and B-type natriuretic peptide (BNP) levels. Point-of-care ultrasound (POCUS) has become a mainstream tool for diagnosis and treatment in the field of emergency medicine, as well as in various other departments in the hospital setting. Currently, the main methods of diagnosis of ADHF using POCUS are pleural B-lines and inferior vena cava (IVC) width and respiratory variation.

Objectives: To examine the potential use and benefits of bedside ultrasound of the jugular veins in the evaluation of dyspneic patients for identification of ADHF.

Methods: A blood BNP level was drawn from each participant at time of recruitment. The area and size of the internal jugular vein (IJV) during inspiration and expiration were examined.

Results: Our results showed that the respiratory area change of the IJVs had a specificity and sensitivity of nearly 70% accuracy rate in indentifying ADHF in our ED.

Conclusions: Ultrasound of the IJV may be a useful tool for the diagnosis of ADHF because it is easy to measure and requires little skill. It is also not affected by patient body habitus.

Cesarean section has undergone a transformation that has radically changed the prognosis of both the pregnant woman and her unborn child. The attributed mortality rate of Cesarean section during the 19th century was over 50% worldwide. Today, mortality from Cesarean delivery is rare. However, the technique of transversely incising the uterus in its lower uterine segment, although less than a century old, is passed on from instructor to apprentice, often without either of them being aware of its noble history. In this brief review, we discuss the reported history regarding this incision and the significant role played by John Munro Kerr.

Cardiac patients of all ages were managed in the past by internists who specialized in cardiology. During the past 50 years, the medical field has witnessed great strides in the management of congenital heart disease, and thus pediatric cardiology has become a subspecialty in many countries. This review article focuses on the advances in fetal cardiac interventions (FCI) since its inception by our group in 1975. Three major modes of FCI have evolved during the past 42 years: pharmacologic, closed FCI, and open FCI. All treatments require a careful approach by the heart team and are reserved for severe fetal cardiac conditions. They call for prenatal intervention in view of the severity and progressive nature of the diseases that are associated with high fetal morbidity and mortality if left untreated. The well-established pharmacologic FCI approach includes several new and effective agents with recommendations often varying between class I and class IIa and IIb. The advances in prenatal echocardiographic imaging and color flow Doppler has given an impetus to the development of the other FCI modes; however, the need for uterine incision and fetal cardiac bypass in the open technique have limited its advance. Long-term outcomes are still unknown and definite conclusions as to the efficacy and safety of FCI need further investigation, including multicenter trials with long-term data.
