Background: The French AmbUlatory Cesarean Section (FAUCS) technique was introduced to the Galilee Medical Center in September 2021. FAUCS was performed electively for interested women who meet the criteria.

Objectives: To evaluate the learning curve of senior surgeons performing FAUCS, the procedure short-term outcomes, and complications.

Methods: This retrospective study included 50 consecutive women who underwent FAUCS from September 2021 until March 2022 at our facility. Preoperative, intraoperative, postoperative, and demographic data were retrieved from patient electronic charts.

Results: The mean duration of surgery was 53.26 ± 11.62 minutes. This time decreased as the surgical team's experience increased: from a mean 58.26 ± 12.25 minutes for the first 15 procedures to a mean 51.17 ± 9.73 minutes for subsequent procedures. The mean visual analogue scale score for 24 hours was 1.08 ± 0.84 (on a 10-point scale). The rate of neonatal cord pH < 7.2 was 6%, and there were 11.3% cases of vacuum assisted fetal extraction. In total, 44% of the women were able to mobilize and urinate spontaneously by 4–6 hours. Complications included bladder injury (n=1), endometritis (n=1), and incisional hematoma (n=1). Overall, the maternal satisfaction rate was high; 94% of the women would recommend FAUCS to others.

Conclusions: FAUCS is a feasible procedure with a high satisfaction rate. Following the first 15 procedures performed by one surgical team, the operative time decreased considerably. Further randomized controlled studies are needed to compare this procedure to regular cesarean section and evaluate neonatal outcomes.

Background: Implantable loop recorders (ILRs) are a central tool in the evaluation of unexplained syncope. These devices record and store electrocardiograms, both automatically and on patient-dependent activation. Therefore, obtaining optimal diagnostic results relies on a patient's comprehension and collaboration.

Objectives: To evaluate the effect of ethnic background and mother-tongue language on the diagnostic yield (DY) of ILRs.

Methods: Patients at two medical centers in Israel, who had ILRs as part of syncope workup were included. Inclusion criteria were age over 18 years and an ILR for at least one year (or less if the cause of syncope was detected). Patient demographics, ethnic background, and previous medical history were recorded. All findings from ILR recordings, activation mode (manual vs. automatic), and treatment decisions (none, ablation, device implantation) were collected.

Results: The study comprised 94 patients, 62 Jews (i.e., ethnic majority) and 32 non-Jews (i.e., ethnic minority). While baseline demographic characteristics, medical history, and drug therapy were similar in both groups, Jewish patients were significantly older at the time of device implantation: 64.3 ± 16.0 years of age vs. 50.6 ± 16.9, respectively; (P < 0.001). Arrhythmias recorded in both groups as well as treatment decisions and device activation mode were similar. Total follow-up time from device implantation was longer in the non-Jewish vs. the Jewish group (17.5 ± 12.2 vs. 24.0 ± 12.4 months, respectively; P < 0.017).

Conclusions: The DY of ILR implanted for unexplained syncope did not seem to be influenced by patient's mother-tongue language or ethnicity.

Background: Statins have anti-inflammatory effects that are independent of their lipid-lowering activity.

Objectives: To examine whether prior statins therapy affects the clinical course of the first episode of acute idiopathic pericarditis (AIP) as the 1-year recurrence and length of hospitalization (LOH).

Methods: This retrospective study included 148 subjects with first episode AIP admitted between the years 2015 and 2019. Data were collected from two hospitals in Northern Israel. We divided the patients in into two groups: 117 those without statins use and 31 those with prior statins use. We compared age, sex, co-morbidities, drugs, laboratory data, 1-year recurrence, and LOH.

Results: The mean age of participants was 43.1 ± 19.4 years. Comparisons between subjects without statins and with prior statins use were made according to age (37.5 ± 16.7 years vs. 64.4 ± 12.7 years, P < 0.01), C-reactive protein (50 ± 40 vs. 48 ± 35 mg/dl, P = 0.9), LOH (5.4 ± 2.85 vs. 8.03 ± 4.92 days, P < 0.01), 1-year recurrence of pericarditis (23 vs. 6 cases, P = 0.95), respectively. Multivariate logistic regression analysis revealed that 1-year recurrence (odds ratio [OR] 0.8, 95% confidence interval [95%CI 0 0.6–1.1, P = 0.41), was not associated with prior statin use, while LOH (OR 2.56, 95%CI 2.08–2.75, P = 0.01) was prolonged with prior statins use in patients with first episode of AID.

Conclusions: Prior statins use in patients with the first episode of AIP did not reduce the 1-year recurrence of pericarditis and prolong the LOH.

A 47 year old man presented with a combination of dry mouth and lightheadedness while standing. His medical background was unremarkable except for cigarette smoking and hyperlipidemia. Sjögren’s syndrome was ruled out, and he was referred for evaluation of orthostatic hypotension, which by then included syncopal episodes and injuries. Additional symptoms included dry eyes, constipation, reduced sweating, and erectile dysfunction. After excluding medications and structural cardiac abnormalities as causes of orthostatic hypotension, a clinical autonomic evaluation was performed. The pattern of beat-to-beat blood pressure associated with performance of the Valsalva maneuver, and a low plasma norepinephrine level that did not increase in response to standing, established that the orthostatic hypotension was neurogenic. Treatment with an alpha-adrenoceptor agonist and fludrocortisone yielded partial improvement. After systemic diseases involving autonomic failure were excluded, cardiac sympathetic neuroimaging was performed by ¹²³I-metaliodobenzylguanidine (MIBG) scanning. The normal uptake seen in the heart indicated intact post ganglionic sympathetic innervation. There were no signs of central neurodegeneration or peripheral neuropathy. Because of symptoms and signs of both parasympathetic and sympathetic failure without denervation, an autonomic ganglionopathy was considered. A high titer of antibody to the neuronal nicotinic receptor, which mediates ganglionic neurotransmission, was obtained. The diagnosis of autoimmune autonomic ganglionopathy (AAG) was made, and the management strategy shifted to first lowering the antibody burden by plasma exchanges and then instituting chronic anti-autoimmune treatment with rituximab and a low dose of cortiosteroid. The patient showed remarkable improvement.

Objectives: To study the effects of purified allicin on the cardiovascular system.

Methods: Spontaneously hypertensive rats treated for 6 weeks with a daily dose of 80 mg/kg/day of purified allicin added to their chow were compared to control rats that were fed regular chow. Weight, systolic blood pressure (SBP), triglycerides, cholesterol, insulin and adiponectin were measured at baseline and at the end of the study.

Results: Allicin had no effect on body weight whereas it reduced SBP significantly from 190 ± 7.5 mmHg to 168 ± 5.7 (P < 0.0001) and triglyceride levels from 96 ± 25 mg/dl to 71 ± 19 (P =0.009). Allicin had no effect on plasma cholesterol, insulin and adiponectin levels.

Conclusions: Allicin lowers blood pressure and triglyceride levels in spontaneously hypertensive rats. This effect is not mediated through weight loss.

Background: Splanchnic nerve stimulation evokes adrenomedullary catecholamine secretion via acetylcholine release and occupation of nicotinic cholinergic receptors on chromaffin cells.

Objectives: To assess whether among cultured adrenomedullary cells there exists a population that tonically secretes acetylcholine. If so, then blockade of enzymatic breakdown of acetylcholine by addition of a cholinesterase inhibitor to the medium would increase occupation of nicotinic receptors by endogenous acetylcholine and thereby induce catecholamine release.

Methods: Primary cultures of bovine adrenomedullary cells in 24-well plates (1 million cells per well) were incubated after 48–72 hours with fresh incubation medium (control), medium with added secretagogues (nicotine, angiotensin II, or K+) or the acetylcholinesterase inhibitor, edrophonium (10-7 to 10-³ M), for 1–20 minutes. Fractional release rates of epinephrine, norepinephrine and dopamine were compared to a control. We also examined whether co-incubation with edrophonium enhanced the effects of the secretagogues. All experiments were performed in quadruplicate and repeated three times.

Results: Nicotine, angiotensin II, and K+ each elicited time-related release of epinephrine, norepinephrine and dopamine by up to fourfold compared to the control. At all tested concentrations, edrophonium had no such effect. Co-incubation with edrophonium also failed to augment the secretory responses to nicotine, angiotensin II, or K+.

Conclusion: Bovine adrenomedullary cells in primary culture do not include a population of tonically active cholinergic cells.

Background: Some studies have indicated a possible link between cigarette smoking and hearing loss.

Objectives: To analyze the association between smoking and hearing loss, other than that induced by noise, and to characterize the type of HL impairment found in smokers.

Methods: We conducted a retrospective cross-sectional study in 13,308 men aged 20±68 (median 34.6 years) who underwent a hearing test as part of a routine periodic examination. For each subject, age, smoking status (current, past or non-smokers) and number of cigarettes per day were noted and a hearing test was performed. The test was performed in a sealed, soundproof room by an experienced audiologist and included pure tone audiometry of 250±8,000 Hz. The audiograms were analyzed and subjects were accordingly divided into two groups: those with HL and at least one of the following impairments in at least one ear: sensorineural, conductive or mixed; and those with no hearing loss (control). Audiograms showing HL typical to noise exposure were excluded.

Results: The prevalence of any type of HL among subjects <35 years was 4.5%, compared to 10.5% among those >35 years (P < 0.0001). A significantly higher incidence of any type of HL was found in current (11.8%) and past smokers (11.7%) than in non-smokers (8.1%) (P < 0.0001). The risk increment of the smoking status for developing HL among subjects under age 35 was 43%, and 17% among those above 35 years. Both mild, flat, sensorineural impairment and conductive impairment were found to be associated particularly with smoking (odds ratio 2.2 and 1.9, respectively).

Conclusions: The incidence of HL unrelated to noise exposure is higher in smokers than in non-smokers, and in young adults the effect is greater.
