Lacrimal sac diverticulum: clinical presentation and endoscopic management.

Background: To describe the clinical presentation, surgical intervention and clinical outcomes of patients with a lacrimal sac diverticulum.

Methods: Retrospective chart review of all patients who underwent endonasal endoscopic dacryocystorhinostomy (DCR) in a single medical center from January 2010 to October 2020. The diagnosis of a lacrimal sac diverticulum was based upon intraoperative findings.

[FACIAL NERVE PARALYSIS - THERAPEUTIC APPROACH, FACIAL REANIMATION AND ADJUNCTIVE TREATMENT].

Paralysis of the facial mimetic muscles causes loss of voluntary and non-voluntary muscle function, as well as facial tone. This is a devastating condition with profound functional, aesthetic and psychological consequences. Etiologies include congenital paralysis and acquired paralysis following viral infection, trauma, head and neck tumors, iatrogenic damage and more.

Intense focused ultrasound for neck and lower face skin tightening a prospective study.

Background: Intense focused ultrasound (IFUS) is a Nonablative skin tightening technology with good safety profile, but limited efficacy. Most clinical studies have been performed to evaluate the efficacy of the Ulthera IFUS (Ulthera, Mesa, AZ) in treating redundant skin.

Objective: To report our experience with Doublo IFUS (Doublo™, HIRONIC Co.

Avoiding dacryocystorhinostomy in cases of epiphora caused by inferior meatus obstruction.

Aims: To determine the role of inferior meatus pathologies as an underdiagnosed cause of epiphora.

Methods: This study was conducted in the oculoplastic institution of Tel Aviv medical center-a regional referral center. A retrospective review of files of patients presenting to the lacrimal clinic with nasolacrimal duct obstruction between October 2010 and September 2016.

Incomplete Facial Paralysis: The Use of the Ipsilateral Residual Facial Nerve as a Donor Nerve for Facial Reanimation.

Background: The reconstructive approach for incomplete facial paralysis is not yet determined. In this article, the authors present a new surgical approach for patients with incomplete facial paralysis in which residual, ineffective movement is detected preoperatively in the ipsilateral buccozygomatic territory of the paretic facial nerve.

Methods: Sixteen patients with incomplete facial paralysis were found eligible for the procedure and underwent one-stage facial reanimation performed by the senior author (E.

Trends and predictors of prehospital delay in patients undergoing primary coronary intervention.

Objective: Delay in seeking medical care following symptom onset in patients with acute ST-elevation myocardial infarction (STEMI) is related to increased morbidity and mortality. Actual trends of prehospital delays in patients hospitalized with STEMI have not been well characterized. We evaluated trends in the length of time that had elapsed from symptom onset to hospital presentation among STEMI patients admitted to our hospital.

Trial of labor following one previous cesarean delivery: the effect of gestational age.

Purpose: To stratify maternal and neonatal outcomes of trials of labor after previous cesarean delivery (TOLAC) by gestational age.

Methods: Retrospective cohort study of all singleton pregnancies with one previous cesarean delivery in TOLAC at term between 2007 and 2014. We compared outcomes of delivery at an index gestational week, with outcomes of women who remained undelivered at this index gestational week (ongoing pregnancy).

CRP velocity and short-term mortality in ST segment elevation myocardial infarction.

Context: There is a known association between C-reactive protein (CRP) levels and adverse outcomes in patients presenting with ST-elevation myocardial infarction (STEMI). The optimal time frame to measure CRP for risk stratification is not known.

Objective: The aim of the current study was to evaluate the relation between the change in CRP velocity (CRPv) and 30-d mortality among STEMI patients.

The implications of body-image dissatisfaction among kidney-transplant recipients.

The role that body image plays in the psychological adjustment of kidney-transplant recipients is an understudied issue. In the current study, the association between three variables - (a) body-image dissatisfaction, (b) quality of life (QOL), and (c) psychological distress - was investigated. The research participants were 45 kidney-transplant recipients who were under follow-up care at the Transplant Unit of the Tel-Aviv Medical Center (Israel).

Involvement of CXCR4/CXCR7/CXCL12 Interactions in Inflammatory bowel disease.

Directional movement of cells in the human body is orchestrated via chemokines. This migration was initially identified in pathological and immunological processes but quickly extended to homeostatic cell trafficking. One such chemokine is the ubiquitous CXCL12 (initially called SDF1-α) which signals via the chemokine receptors CXCR4 and CXCR7.

Increased serum levels of oxidative stress are associated with hospital readmissions due to acute heart failure.

Objectives: Inflammation and serum oxidative stress (OS) are important components in heart failure (HF) deterioration. In this study we tested the hypothesis that an increase in patients' sera OS levels is associated with acute HF (AHF) readmissions.

Methods: Thirty consecutive patients (mean age 71 ± 10 years) admitted with AHF were included in the study.

Intrasplenic preconditioning: a model for the study of xenostimuli accommodation.

Background: Discordant xenotransplantation, the grafting of organs from one phylogenic species to another, results in hyper-acute rejection (HAR). HAR is associated with the deposition of recipient preformed xenoreactive natural antibodies and complement on the endothelium of the donor organ, leading to activation and apoptosis of the endothelium, an event associated with xenograft rejection. Endothelial resistance to HAR, termed "accommodation," an active protection of graft endothelium, may be achieved by previous stimulation of endothelial cells by discordant xenoantibodies.

Automated system to detect low-grade underlying inflammatory profile: Gaucher disease as a model.

Patients with Gaucher disease, perhaps due to chronic storage of glycolipids, apparently harbor a subclinical or underlying inflammation. Quantification of a baseline inflammatory profile in patients with Gaucher disease is more impressive when compared with that of matched healthy controls in a systematic, automated fashion. A mean of 16 healthy controls was generated for each of 50 patients with Gaucher disease by applying variables relating to potential for inflammatory features, for example, atherothrombotic risk factors.

Exercise Radionuclide Cineangiography for Predicting Long Term Prognosis in Elderly Post Coronary Artery Bypass Graft Patients.

ISSUE: The immediate benefits of coronary artery bypass grafting may only be transient. Recent studies which showed that exercise radionuclide cineangiography studies may predict cardiac events and survival had evaluated post coronary artery bypass grafting patients of all ages. This prospective study was done on an elderly subgroup.

[Isolated limb perfusion with tumor necrosis factor for malignancies of the limbs].

Tumor necrosis factor (TNF) induces rapid necrosis in a variety of experimental neoplasms. However, its clinical application is limited by life-threatening systemic toxicity. Isolated limb perfusion (ILP) enables administration of large doses of TNF and cytotoxic drugs directly to the affected limb, avoiding systemic toxicity.
