Pheochromocytoma manifesting as cortical blindness secondary to PRES with associated TMA: a case report and literature review.

Background: Pheochromocytomas are neoplasms originating from neuroectodermal chromaffin cells leading to excess catecholamine production. They are notorious for causing a triad of headaches, palpitations, and sweats. Though the Menard triad is one to be vigilant of, symptomatic presentation can vary immensely, hence the tumor earning the label "the great masquerader.

Recurrent Hypoglycemia Due to a Massive Abdominal Tumor in a Nonagenarian: A Case Report and Review of the Literature.

BACKGROUND Whipple's triad is a rare condition that prompts urgent investigation. A rare cause of such a clinical presentation is excess production of insulin-like growth factor 2 (IGF-2) from a solitary fibrous tumor. CASE REPORT A 94-year-old man presented to the hospital following episodes of confusion, gait disturbance, and multiple falls secondary to hypoglycemia.

Bilateral Lumbar Hernias Following Spine Surgery: A Case Report and Laparoscopic Transabdominal Repair.

Lumbar hernias are rare abdominal wall defects. Fewer than 400 cases have been reported in the literature and account for 2% of all abdominal wall hernias. Lumbar hernias are divided into Grynfelt-Lesshaft or Petit hernias.

Laparoscopic Hiatal Hernia Repair with Falciform Ligament Buttress.

Background: Using synthetic mesh to buttress the crural repair during laparoscopic hiatal hernia repair may be associated with dysphagia and esophageal erosions, while a biologic mesh is expensive and does not decrease long-term recurrence rates. This study documents outcomes of laparoscopic paraesophageal hernia repairs using the falciform ligament to reinforce the crural repair.

Methods: This is a prospective study of laparoscopic paraesophageal hernia repairs with a falciform ligament buttress.

Analysis of Minimally Invasive Esophagectomy at a Single Veterans Affairs Medical Center.

Background: To date, there are no published studies focusing on the benefits of minimally invasive esophagectomy (MIE) versus open esophagectomy at a Veterans Affairs Medical Center (VAMC). Our primary outcome was the incidence of esophageal malignancy in the veteran population and the postoperative morbidity following traditional and MIE for malignancy.

Design: Retrospective analysis of the incidence of esophageal malignancy at a Veteran Integrated Service Network (VISN) 5 VAMC reported to the VAMC Esophageal Tumor Registry between 2003 and 2016 and outcomes of the veterans who received esophagectomy for malignancy.

Does surgery or radiation therapy impact survival for patients with extrapulmonary small cell cancers?

Background And Objectives: Extrapulmonary small cell carcinomas (EPSCC) are rare tumors where therapy remains poorly defined. We sought to determine the impact of surgical extirpation and radiation therapy for outcomes of EPSCC.

Methods: The Surveillance, Epidemiology, and End Results (SEER) database was queried for patients with EPSCC which were further categorized by site and evaluated for survival by specific treatment strategy.

Changes in relative glucose metabolic rate following cortisol administration in aging veterans with posttraumatic stress disorder: an FDG-PET neuroimaging study.

The authors aimed to examine central glucocorticoids effects by measuring relative glucose metabolic rate (rGMR) in the hippocampus, amygdala, and anterior cingulate cortex (ACC) and the relationship between amygdala and ACC activity. The participants were male combat veterans with and without PTSD, 52 to 81 years old. The authors utilized randomized, double-blind, placebo-controlled examinations of the rGMR response to 17.

Parental posttraumatic stress disorder as a vulnerability factor for low cortisol trait in offspring of holocaust survivors.

Context: Lower cortisol levels in posttraumatic stress disorder (PTSD) may reflect a preexisting vulnerability associated with developing the disorder after trauma exposure. Because offspring of trauma survivors with PTSD have a greater prevalence of PTSD after their own life events than offspring of trauma survivors without PTSD and offspring of nonexposed persons, examination of patterns of basal cortisol secretion in such offspring provides an opportunity to test this hypothesis.

Objective: To characterize the patterns of basal cortisol secretion in offspring of Holocaust survivors with and without parental PTSD and children of nonexposed parents.

Are adult offspring reliable informants about parental PTSD? A validation study.

We developed a short questionnaire--Parental PTSD Questionnaire--(PPQ), designed to assess the presence of posttraumatic stress disorder (PTSD) symptoms in parents. Fifty-eight adult offspring of Holocaust survivors (23 men and 35 women) completed the questionnaire about a parent who was independently evaluated by a trained clinician using the Clinician Administered PTSD Scale (CAPS). Only 5.

24-week oral ganciclovir prophylaxis in kidney recipients is associated with reduced symptomatic cytomegalovirus disease compared to a 12-week course.

Background: Cytomegalovirus (CMV) infection is associated with reduced graft and patient survival among kidney recipients. The highest risk of CMV infection occurs in CMV-naive recipients of kidneys from seropositive donors (D+/R-). Optimal CMV prophylaxis is not established.

Effect of sertraline on glucocorticoid sensitivity of mononuclear leukocytes in post-traumatic stress disorder.

This study examined the effects of sertraline (SER) on glucocorticoid sensitivity in mononuclear leukocytes (MNL) from eight subjects with current post-traumatic stress disorder (PTSD) and nine comparison subjects. In all, 60 ml of blood was withdrawn by venipuncture at 0800, and MNL were isolated from blood and divided into two portions: the first contained live cells incubated with a series of concentrations of dexamethasone (DEX); the second contained cells incubated with similar concentrations of DEX+2 muM SER. Group difference in the concentrations of DEX required to inhibit lysozyme activity by 50% were evaluated under conditions of DEX-only and DEX+SER using analysis of covariance (ANCOVA).

Relationship between cortisol and age-related memory impairments in Holocaust survivors with PTSD.

Rationale: Holocaust survivors with PTSD appear to show an accelerated aging effect as evidenced by their performance on tests of explicit memory, and also show more exaggerated patterns on age-related alterations in cortisol release over the diurnal cycle than Holocaust survivors without PTSD and nonexposed subjects. To investigate the implications of age-related HPA axis alterations on cognition, we examined correlations between parameters reflecting circadian cortisol release and implicit and explicit memory performance.

Methods: Nineteen Holocaust survivors with PTSD (7 men, 12 women), 16 Holocaust survivors without PTSD (7 men, 9 women), and 28 non-exposed healthy comparison subjects (13 men, 15 women) collected salivary samples at six times over the diurnal cycle, and were tested with Paired Associates and Word Stem Completion Tests.

Expanded-criteria donor kidneys: a single-center clinical and short-term financial analysis--cause for concern in retransplantation.

Background: Expanded-criteria donor (ECD) kidneys are associated with a higher risk of posttransplant failure, but they remain a favorable alternative to dialysis. Now that a uniform definition of "expanded criteria" exists, it is more appropriate than ever to evaluate their utility compared with that seen with non-ECD kidneys.

Methods: The authors analyzed 202 cadaveric kidney-only recipients that underwent transplantation from January 1999 to September 2001, including 45 (22%) recipients whose donors met current ECD criteria.

Use of EBV PCR for the diagnosis and monitoring of post-transplant lymphoproliferative disorder in adult solid organ transplant patients.

Epstein-Barr virus (EBV) is known to be involved in the majority of patients who develop post-transplant lymphoproliferative disorder after solid organ transplant. We conducted a retrospective study to determine the utility of qualitative and quantitative Epstein-Barr virus polymerase chain reaction (PCR) for the diagnosis and monitoring of post-transplant lymphoproliferative disorder in adult solid organ transplant patients. Peripheral blood leukocytes obtained from 35 adult solid organ transplant patients consecutively referred for evaluation of possible post-transplant lymphoproliferative disorder, were tested by EBV PCR at the time of initial evaluation and at time points thereafter.

Comparison of open, laparoscopic, and hand-assisted approaches to live-donor nephrectomy.

Background: Minimally invasive donor nephrectomy has become a favored procedure for the procurement of kidneys from live donors. The optimal minimally invasive surgical approach has not been determined. In the current work, we compared the outcome of kidneys procured using the traditional open approach with two minimally invasive techniques: the standard laparoscopic procedure and a hand-assist procedure.

Association of hepatitis C with posttransplant diabetes in renal transplant patients on tacrolimus.

Posttransplant diabetes mellitus (PTDM) remains a common complication of immunosuppression. Although multiple risk factors have been implicated, none have been clearly identified as predisposing to the increased PTDM frequency observed in patients on tacrolimus. Hepatitis C virus (HCV) has been associated with diabetes and is a significant renal transplant comorbidity.
