Background: Transurethral prostatectomy is the gold standard surgical treatment of bladder outlet obstruction due to benign enlargement of the prostate, with more than 30,000 procedures performed annually in the United States alone. The success rate of this minimally invasive procedure is high and the results are durable. The development of urethral stricture is a long-term complication of the procedure and is noted in about 2% of patients. The stricture narrows the urethral lumen, leading to re-appearance of obstructive urinary symptoms. Traditionally, the evaluation of the stricture was performed by retrograde urethrography. Advancements in the fields of flexible endoscopy allowed rapid inspection of the urethra and immediate dilatation of the stricture in selected cases.

Objectives: To compare the efficacy of urethrography versus cystoscopy in the evaluation of urethral strictures following transurethral prostatectomy.

Methods: A retrospective review was conducted of a series of 32 consecutive patients treated due to post-transurethral resection of prostate (TURP) urethral stricture.

Results: Twenty patients underwent both tests. In 16 there was concordance between the two tests. Four patients had no pathological findings in urethrography but had strictures in cystoscopy. All strictures were short (up to 10 mm) and were easily treated during cystoscopy, with no complaints or re-surgery needed in 24 months follow-up.

Conclusions: Cystoscopy was superior to urethrography in the evaluation of post-TURP strictures. Strictures where often short and treated during the same procedure. We recommend that cystoscopy be the procedure of choice in evaluating obstructive urinary symptoms after TURP, and retrograde urethrography be preserved for selected cases.

Background: Prophylactic cranial irradiation (PCI) exclusion in favor of brain magnetic resonance imaging (MRI) staging and surveillance in the management of small cell lung cancer (SCLC) is controversial yet accepted by some centers. The use of MRI suggests performing stereotactic radiosurgery (SRS) treatment for limited brain metastases. Data regarding SRS efficacy in this setting is limited.

Objectives: To assess intracranial objective response rate (iORR), progression-free survival (iPFS), intracranial failure patterns, overall survival (OS) and time-to-whole-brain radiation therapy (WBRT)/death, whichever occurred first (TTWD) with SRS in SCLC.

Methods: The study comprised 10 consecutive SCLC patients with brain metastases treated with SRS and followed-up at Davidoff Cancer center between Aug 2012 and March 2019. Brain MRI images were reviewed by a neuro-radiology specialist.

Results: iORR was 57% as assessed by response assessment in neuro-oncology brain metastases. Intracranial progression developed in 8 patients. Median iPFS was 4.0 months (95% confidence interval [95%CI] 1.7–7.2). In-site, off-site and combined pattern of intracranial failure was seen in 0, 5, and 3 patients, respectively; median number of new brain lesions following SRS was 4 (range, 1–12). SRS was performed 10 additional times in 6 patients (median number of lesions irradiated per round was 1, range 1–5). WBRT was administered in 3 patients. Median TTWD was 20.9 months (95% CI, 1.9–26.8). Median OS since SRS administration was 23.2 months (95% CI, 4.2–not reached).

Conclusions: MRI surveillance with multiple rounds of SRS may serve a reasonable alternative to PCI or therapeutic WBRT in SCLC. 

Recurrent pericarditis is a state of repetitive inflammation of the pericardium with intervals of remission. The etiology of recurrent pericarditis is still largely unknown, yet most causes are presumed to be immune mediated. Genetic factors, including human leukocyte antigen (HLA) haplotypes, can be involved in dysregulation of the immune system and as a predisposition to several autoimmune conditions, including recurrent pericarditis. Several diseases are frequently associated with such manifestations. They include systemic lupus erythematosus, familial Mediterranean fever, and tumor necrosis factor receptor-associated periodic syndrome. However, idiopathic recurrent pericarditis remains the most frequently observed clinical condition and the conundrum of this disease still needs to be solved.

Erectile dysfunction (ED) is a syndrome associated with endothelial dysfunction, which may predict cardiovascular events in men presenting with this syndrome. It has been shown to be associated with a higher rate of acute myocardial infarction and cardiovascular mortality, vascular inflammation, and impaired endothelial function. In this review we present the literature findings and describe the mechanistic pathways that are known to be involved in this syndrome and its related clinical consequences.

Background: Previously described as a subcategory of obsessive compulsive disorder (OCD), hoarding disorder was added to the fifth Diagnostic and Statistical Manual of Mental Disorders (DSM-V) as a stand-alone diagnosis for the first time. The first formal research in the 1990s surprisingly found no connection between material deprivation early in life and hoarding; however, later studies linked early traumatic life experiences with hoarding. Subsequent familial studies demonstrated a genetic predisposition for hoarding. Emerging evidence suggests a link between a post-traumatic stress disorder (PTSD) and hoarding in Jewish Holocaust survivors.

Objectives: To evaluate the literature on PTSD among Jewish Holocaust survivors for associations between PTSD and hoarding.

Methods: A systematic search of selected databases, including PubMed, Google Scholar, NCBI, Psych Info, and EBSCO Host was conducted from 1 March 2017 to 15 July 2018 using the following search terms: hoarding, hoarding disorder, obsessive compulsive disorder, OCD, compulsive hoarding, Jewish Holocaust survivors, Shoa, post-traumatic stress disorder, and PTSD. Inclusion criteria included peer reviewed research published on adults in English since 1990. Because no publications linking hoarding and PTSD in Jewish Holocaust survivors were found, references in retained papers were also searched for any relevant published work.

Results: Seven articles linking PTSD and hoarding were identified for this review. However, no articles were found linking PTSD and hoarding in Jewish Holocaust survivors.

Conclusions: A relationship between PTSD and hoarding in Jewish Holocaust survivors is conceivable and should be explored to effectively diagnose and care for affected individuals.

Background: Increasing antibiotic resistance in the community results in greater use of empiric broad spectrum antibiotics for patients at hospital admission. As a measure of antibiotic stewardship it is important to identify a patient population that can receive narrow spectrum antibiotics.

Objectives: To evaluate resistance patterns of Escherichia coli bloodstream infection (BSI) from strictly community-acquired infection and the impact of recent antibiotic use on this resistance.

Methods: This single center, historical cohort study of adult patients with E. coli BSI was conducted from January 2007 to December 2011. Patients had no exposure to any healthcare facility and no chronic catheters or chronic ulcers. Data on antibiotic use during the previous 90 days was collected and relation to resistance patterns was assessed.

Results: Of the total number of patients, 267 BSI cases met the entry criteria; 153 patients (57%) had bacteria sensitive to all antibiotics. Among 189 patients with no antibiotic exposure, 61% of isolates (116) were pan-sensitive. Resistance to any antibiotic appeared in 114 patients and 12 were extended-spectrum beta-lactamase (ESBL) producers. Quinolone use was the main driver of resistance to any antibiotic and to ESBL resistance patterns. In a multivariate analysis, older age (odds ratio 1.1) and quinolone use (odds ratio 7) were independently correlated to ESBL.

Conclusions: At admission, stratification by patient characteristics and recent antibiotic use can help personalize primary empirical therapy.

Background: Fractures of the distal radius are the most common fractures in the upper extremity, and their incidence is increasing with the aging of the population. Despite anatomical reduction of the bones, many patients complain of residual pain. A reason for this may be ligament injury not addressed during surgery or conservative treatment. Radiographic measurements may allow assessment of ligament integrity but they may be population specific and differ among races.

Objectives: To assess radiographic wrist measurements in an Israeli population and to compare them to existing values.

Methods: Demographic data, previous diagnosis of osteoporosis, fracture classification, and radiologic measurements (radial height, radial inclination, ulnar variance, volar tilt, and d2/w2) were measured and compared.

Results: The study was comprised of 53 females and 27 males, mean age 64 years, with wrist radiographs following surgery. Of these, 13% were smokers and 38.5% had osteoporosis. According to the Arbeitsgemeinschaft für Osteosynthesefragen classification system, most of the fractures were comminuted and intra-articular. The mean values for all measurements did not differ significantly from values in the literature. The average d2/w2 ratio (describing the radiocarpal ligaments) was 0.42, significantly differing from this measurement in normal wrists as described in the literature, but similar to a population following surgery (P = 0.002).

Conclusions: Our population had more fragility fractures than other populations. Otherwise, our demographics and measurements did not differ from normal values described in the literature. This study supports the validity of any wrist radiographic study performed in our population.

Background: Multiform fascicular tachycardia (FT) was recently described as a ventricular tachycardia (VT) that has a reentrant mechanism using multiple fascicular branches and produces alternate fascicular VT forms. Ablating the respective fascicle may cause a change in the reentrant circuit resulting in a change in morphology. Ablation of the septal fascicle is crucial for successful treatment.

Objectives: To describe four cases of FT in which ablation induced a change in QRS morphologies and aggravated clinical course.

Methods: Four out of 57 consecutive FT cases at three institutions were retrospectively analyzed and found to involve multiform FT. These cases underwent electrophysiological study, fascicular potential mapping, and electroanatomical mapping. All patients initially had FT with right bundle branch block (RBBB) and superior axis morphology.

Results: Radiofrequency catheter ablation (RFCA) targeting the distal left posterior fascicle (LPF) resulted in a second VT with an RBBB-inferior axis morphology that sometimes became faster and/or incessant and/or verapamil-refractory in characteristics. RFCA in the upper septum abolished the second VT with no complications and uneventful long-term follow-up.

Conclusions: The change in FT morphology during ablation may be associated with a change in clinical course when shifting from one route to another and may aggravate symptoms. Targeting of the proximal conduction system (such as bifurcation, LPF, left anterior fascicle, high septal/auxiliary pathway) may serve to solve this problem.

Background: Preterm birth is the leading cause of morbidity and mortality among neonates in the United States. Early recognition of sepsis in this population is a challenging task since overt clinical signs can be difficult to determine. C-reactive protein (CRP), one of the most frequently non-specific used laboratory test, can indirectly aid the diagnosis of neonatal sepsis.

Objectives: To evaluate the relationship between histological findings in the placenta of preterm newborns born after prolonged rupture of membranes, CRP levels, and blood cultures.

Methods: Medical records were reviewed of all preterm newborns born after prolonged premature rupture of membranes at a medical center in Israel between 2011 and 2014.

Results: Of 128 newborns with prolonged rupture of membranes, 64 had evidence of histological chorioamnionitis (HCA). Gestational age, birth weight, and Apgar scores were significantly lower, while CRP levels (on admission and 10–12 hours post-delivery) were significantly higher in preterm newborns born to mothers with histological evidence of chorioamnionitis, but values were within normal ranges. Duration of the rupture of membranes and white blood cell counts did not differ between groups.

Conclusions: CRP levels taken on admission and 10–12 hours after delivery were higher when HCA was present, but since there was a substantial overlap between those with and without HCA and the values for most were within normal range, the differences were not enough to serve as a tool to diagnose placental histological chorioamnionitis in preterm infants born after prolonged premature rupture of membranes and exposed to intrapartum antibiotics.
