Gangliosides of cultured astroglia

Cultured astrocytes prepared from newborn rat brain and 13-day-old chick embryonic brain were analyzed qualitatively and quantitatively for ganglioside content. All preparations contained approximately the same total level: 2.4-3.4 micrograms N-acetylneuraminic acid (NeuAc)/mg protein. In contrast, the value for primary cultures of neurons from chick embryonic brain was 5.9. The non-hexosamine-containing species, GM3 and GD3, comprised 75-85% of the total in astroglial cultures, the remainder consisting mainly of structural types other than the gangliotetraose series; choleragenoid assay revealed the latter to be virtually absent or to comprise at most a few percent. Deficiency of gangliotetraose synthesizing ability was indicated by the very low level of UDP-GalNac:GM3 N-acetylgalactosaminyltransferase detected in the cells. Treatment of cultured astrocytes with astroglial growth factor 2 or dibutyryl cyclic AMP caused little if any change in quantity or pattern of gangliosides. The large majority of cells stained in a manner characteristic of astrocytes: positive for glial fibrillary acidic protein, negative for galactosyl ceramides. Staining with cholera toxin and anti-GM1 antibody was essentially negative, as was that with tetanus toxin, A2B5 monoclonal antibody, and antibody to GD3. All evidence thus points to cultured astrocytes of rat and chick brain containing appreciable gangliosides, most of which are GM3 and GD3 with the majority of the remainder comprising structures other than the gangliotetraose type.     

Is same-day discharge associated with increased 30-day postoperative complications and readmissions in patients undergoing laparoscopic adrenalectomy?

BackgroundAdvances in minimally invasive surgery and perioperative care have decreased substantially the duration of time that patients spend recovering in hospital, with many laparoscopic procedures now being performed on an ambulatory basis. There are limited studies, however, on same-day discharge after laparoscopic adrenalectomy. The objectives of this study were to investigate the outcomes and trends of ambulatory laparoscopic adrenalectomy in a multicenter cohort of patients.MethodsAdult patients who underwent elective laparoscopic adrenalectomy between 2005 and 2016 were identified in the database of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). Baseline demographics and 30-day outcomes were compared between patients who underwent ambulatory laparoscopic adrenalectomy and those who were discharged after an inpatient stay. Multivariable logistic regression and Cox proportional hazards modelling were used to investigate the association between same-day discharge and 30-day complications and unplanned readmissions.ResultsOf the 4,807 patients included in the study, 88 (1.8%) underwent ambulatory laparoscopic adrenalectomy and 4,719 (98.2%) were admitted after the adrenalectomy. The same-day discharge group contained fewer obese patients (37.2% vs 50%; P = .04), a lesser proportion of American Society of Anesthesiologists class III patients (45.5% vs 61%; P = .003), and more patients with primary aldosteronism (14.8% vs 6%; P = .002) compared with the inpatient group. After adjustment for confounders, same-day discharge was not associated with 30-day overall complications (OR 1.17, 95% CI 0.35–3.85; P = .80) or unplanned readmissions (HR 2.77, 95% CI 0.86–8.96; P = .09). The percentage of laparoscopic adrenalectomies performed on an ambulatory basis at hospitals participating in the ACS NSQIP remained low throughout the study period (0–3.1% per year) with no evidence of an increasing trend over time (P = .21).ConclusionAmbulatory laparoscopic adrenalectomy is a safe and feasible alternative to inpatient hospitalization in selected patients. Further study is needed to determine the cost savings, barriers to uptake, and optimal selection criteria for this approach.     

Anterior segment findings in AIDS patients with cytomegalovirus retinitis

Background: Anterior segment findings in AIDS patients presenting with cytomegalovirus (CMV) retinitis have not been specifically addressed in the American literature. Methods: Our study evaluated 21 AIDS patients with CMV retinitis. Results: Nineteen (90%) of these patients exhibited corneal endothelial deposits concurrent with CMV retinitis. The endothelial deposits were microscopic, opaque, linear flecks arranged in a reticular-like fashion. Of 42 eyes evaluated, 32 (76%) demonstrated active CMV retinitis. Corneal endothelial deposits were noted in 26 (81%) of the 32 eyes with retinitis. These corneal endothelial deposits were absent in the eyes which did not have CMV retinitis. Conclusion: Meticulous examination of the retina of an HIV-positive or AIDS patient who presents with reticularly arranged, linear, flecked corneal endothelial deposits should be performed to ensure that the diagnosis of CMV retinitis can be ruled out.     

The John Kay Williams Gold Medal of the Royal College of Surgeons of England and Glasgow 2015

This paper describes the clinical treatment of two cases presented by the recipient of the 2015 Bi-collegiate Membership in Orthodontics John Kay Williams Gold Medal of the Royal College of Surgeons of England and Glasgow. The first case describes the management of an 11-year-old male with a class II Division 1 malocclusion with a 9?mm overjet complicated by an upper anterior odontome and moderate upper arch crowding. The second case describes a 14-year-old female with a class III malocclusion with a reverse overjet complicated by moderate lower arch crowding and previously removed upper permanent canines.     

Future ophthalmology practice pattern: A survey of Saudi Board of Ophthalmology residents

Purpose

The main purpose of the study was to examine and identify factors that influence the future practice pattern of Saudi Board of Ophthalmology residents as well as their academic goals. This study also aimed to compare the plans and career goals of the current Saudi ophthalmology residents with a former cohort of Saudi ophthalmology residents.

Fungal Orbital Cellulitis: Presenting Features,Management and Outcomes at a Referral Center

Purpose: To report a series of patients with fungal orbital cellulitis who underwent exenteration surgery and describe presenting features, management and outcomes at a referral center.

Methods: Retrospective case series.

Results: From November 2011 to March 2014, four patients underwent orbital exenteration for fungal orbital cellulitis at the University of Illinois. Three patients had mucormycosis and one had aspergillosis. All patients were treated with intravenous antifungals and underwent orbital exenteration. Two patients were successfully treated with supplemental intra-orbital catheter delivery of amphotericin B. Presenting visual acuity in the affected eye ranged from 20/25 to no light perception. Some level of ophthalmoplegia was present in three patients. Significantly elevated intraocular pressure was found in two patients. All patients with mucormycosis were found to have uncontrolled diabetes mellitus. One patient had a history of myelodysplastic syndrome, chronic hepatitis C infection, polysubstance abuse and Crohn’s disease. Another patient had a history of alcoholic liver cirrhosis, Crohn’s disease treated with systemic immunosuppression and renal cell carcinoma. The patient with aspergillosis had myelodysplastic syndrome and portal hypertension, and the initial presentation resembled giant cell arteritis. Two of four patients died during their hospitalization.

Conclusions: Fungal orbital cellulitis has a high mortality rate despite aggressive antifungal treatment and orbital exenteration performed soon after the diagnosis is confirmed. Patients often have a history of immunosuppression and the onset may be insidious. There must be a high rate of suspicion for fungal orbital cellulitis given the appropriate signs and medical history in order to avoid treatment delay.
