Central auditory processing and word discrimination in patients with multiple sclerosis

Many multiple sclerosis (MS) patients with normal pure tone threshold suffer from difficulties in their hearing especially speech perception in background noise, which is possibly because of incompetence of central auditory processing in this group. Three audiologic tests including gap in noise test (GIN), duration pattern sequence test (DPST) and word discrimination score (WDS) were used for comparing a number of aspects of central auditory processing between patients with MS and normal subjects. Approximate threshold and percent of correct answers in GIN test, percent of correct answers in DPST test and monosyllabic discrimination in WDS test were obtained through cross-sectional non-invasive study conducted on 26 subjects with relapsing-remitting multiple sclerosis who had mean age of 28.9 (SD 4.1) years, and 26 18–40-year-old ones with normal hearing and mean age of 27.7 (SD 5.2). Results of this study demonstrate increased approximate threshold and reduction of percent of correct answers obtained from GIN test in patients with multiple sclerosis (Pv = 0.0001). Furthermore in patients with MS, the average of correct answers in DPST was lower than normal subjects and finally performance of MS subjects in WDS test in quiet environment was correlated with GIN threshold (r = ?/624, Pr = /003). Results of the present study showed that patients with MS had defect in aspects of central auditory processing consisting of temporal resolution, auditory pattern and the memory for auditory task and difficulty in discrimination of speech in noisy environment that are related to the involvement of central nervous system.     

Association of VEGFA,TIMP-3, and IL-6 gene polymorphisms with predisposition to optic neuritis and optic neuritis with multiple sclerosis

ABSTRACT

Background

The etiology of the inflammatory ON is multifactorial. Much attention is paid to the inflammatory and immune processes that are likely to contribute to the demyelination and MS development. IL-6, VEGFA, and TIMP-3 genes are thought to be involved in the inflammatory processes and manifestation of CNS demyelination, so we aimed to determine the relationship between VEGFA rs1413711, TIMP-3 rs9621532, IL-6 rs1800796 gene polymorphisms and ON, and ON with MS.     

Perioperative outcomes after totally robotic gastric bypass: a prospective nonrandomized controlled study

Background

Perioperative short-term outcomes could be improved after totally robotic Roux-en-Y gastric bypass (TR-RYGBP) compared with conventional laparoscopic gastric bypass.

Methods

This is a nonrandomized controlled prospective study (N = 200) to evaluate perioperative short-term outcomes. The primary endpoint was to investigate risk factors for 30-day surgical complications.

Results

Mean total operative time was shorter in patients who underwent TR-RYGBP (130 vs 147 minutes; P < .0001). However, postoperative surgical complications rate (13% vs 1%; P = .001), and mean overall hospital stay (9.3 vs 6.7 days; P < .0001) were higher after TR-RYGBP. By multivariate analysis, robotic surgery (hazard ratio [HR] = 15.1; 95% confidence interval [CI], 2.8 to 280; P = .01), and conversion to laparotomy (HR = 18.8; 95% CI, 1.7 to 250.8; P = .014) were independent risk factors for 30-day surgical complications.

Conclusions

Although robotic gastric bypass reduces mean operative time, TR-RYGBP is associated with an increased postoperative surgical complications rate and longer hospitalization.     

Three-Dimensional CT Volumetry Predicts Outcome of Laparoscopic Splenectomy for Splenomegaly: Retrospective Clinical Study

Background

The aim of this study was to determine the predictive value of the preoperative three-dimensional reconstructed volume (3D volumetry) for outcomes of laparoscopic splenectomy. The impact of splenomegaly on the feasibility of laparoscopic splenectomy is still debated. We hypothesized that splenic volumetry may accurately estimate splenic volume preoperatively and be used by surgeons to select patients for laparoscopic splenectomy.

Methods

We performed a retrospective review of 88 patients seen at a tertiary referral center undergoing laparoscopic or open splenectomy between 2001 and 2010. Patients included in the study underwent elective splenectomy without associated procedures and had preoperative imaging available at our institution. We evaluated clinical, demographic characteristics and perioperative imaging as predictors of outcome. Study endpoints included conversion to open splenectomy, operating time, estimated blood loss (EBL), length of stay (LOS), postoperative complications, and mortality.

Results

In all, 53 procedures were started laparoscopically. Among them, 7 (13.2 %) were converted to open splenectomy and 7 (13.2 %) to hand-assisted laparoscopic splenectomy. The conversion group was matched with 35 patients who underwent open splenectomy to determine differences in outcomes between these groups. There were no conversions in spleens measuring <1100 cc, whereas spleens of 1100 to 2700 cc had a conversion rate of 41 %. Spleen volume >2700 cc was associated with an 87.5 % conversion rate. Spleen 3D volumetry >2700 cc was the only independent predictor of surgical conversion on multivariate analysis (odds ratio 38.0, confidence interval 4.02–358.75, p = 0.001). Patients who underwent open splenectomy had shorter operating times (160.3 vs. 253.0 min, p = 0.001) than those converted from laparoscopic to open splenectomy.

Conclusions

A 3D reconstructed splenic volume of >2700 cc is a predictor of conversion from laparoscopic to open splenectomy. For spleens measuring <2700 cc, laparoscopic splenectomy may be performed by experienced surgeons with low to moderate rates of conversion. For spleens with a 3D reconstructed volume >2700 cc, laparoscopic splenectomy is associated with high rates of conversion to open surgery.     

Trends in periodontal health among 35-year-olds in Oslo, 1973-2003

AIM: The aim of the present study was to describe trends in periodontal health and oral hygiene using data available from four epidemiological studies on 35-year-olds in Oslo performed from 1973 to 2003. MATERIAL AND METHODS: Periodontal status of randomly selected 35-year-olds was assessed clinically and radiographically. Clinical registrations were based on the Community Periodontal Index of Treatment Needs (CPITN) and the Simplified Oral Hygiene Index. In addition, the proportion of individuals with marginal bone loss was assessed using available orthopantomograms. RESULTS: The proportion of persons with CPITN score 4 (one or more pockets > or = 6 mm) decreased from 21.8% in 1984 to 8.1% in 2003. In addition, the mean number of sextants with deep pockets per person was considerably lower in 2003 than previously. The proportion of persons without recorded bone loss increased from 46% in 1973 to 76% in 2003. An improvement in oral hygiene scores was also observed during this period. CONCLUSIONS: The results suggest that periodontal health and oral hygiene have been improving among 35-year-olds in Oslo during the last 30 years.     

Obesity does not increase morbidity of laparoscopic cholecystectomy

Background

Obesity has historically been a positive predictor of surgical morbidity, especially in the morbidly obese. The purpose of our study was to compare outcomes of obese patients undergoing laparoscopic cholecystectomy (LC).

Methods

We reviewed 1382 consecutive patients retrospectively who underwent LC for various pathologies from January 2008 to August 2011. Patients were stratified based on the World Health Organization definitions of obesity: nonobese (body mass index [BMI] < 30 kg/m²), obesity class I (BMI 30–34.9 kg/m²), obesity class II (BMI 35–39.9 kg/m²), and obesity class III (BMI ≥ 40 kg/m²). The primary end points were conversion rates and surgical morbidity. The secondary end point was length of stay.

Results

There were significantly more females in the obesity II and III groups (P = 0.0002). American Society of Anesthesiologists scores were significantly higher in the obesity I, II, and III groups compared with the nonobese (P < 0.05; P < 0.01; and P < 0.0001, respectively). Independent predictors of conversion on multivariate analysis (MVA) included age (P = 0.01), acute cholecystitis (P = 0.03), operative time (P < 0.0001), blood loss (P < 0.0001), and fellowship-trained surgeons (P < 0.0001). Independent predictors of intraoperative complications on MVA included age (P = 0.009), white patients (P = 0.009), previous surgery (P = 0.001), operative time (P < 0.0001), and blood loss (P = 0.01). Independent predictors of postoperative complications on MVA included American Society of Anesthesiologists score (P < 0.0001), acute cholecystitis (P < 0.0001), and a postoperative complication (P < 0.0001). BMI was not a predictor of conversions or surgical morbidity. Length of stay was not significantly different between the four groups.

Conclusions

This study demonstrates that overall conversion rates and surgical morbidity are relatively low following LC, even in obese and morbidly obese patients.     

Is race or ethnicity associated with under-utilization of statins among women in the United States: The study of women's health across the nation

BackgroundRates of statin use among minority women are unclear.HypothesisWe hypothesized that statin use would vary by race/ethnicity with lower rates among minority women compared with Whites.MethodsData from the study of women''s health across the nation, a multiethnic cohort of women collected between 2009 to 2011 were used to examine reported statin use by race/ethnicity and risk profile. Multivariable logistic modeling was performed to estimate the odds ratio (OR) of statin treatment.ResultsOf the 2399 women included, 234 had a diagnosis of atherosclerotic disease (ASCVD), 254 were diabetic (without ASCVD), 163 had an LDL ≥190 mg/dL, and 151 had a 10 year ASCVD pooled risk score ≥7.5%. Statins were used by 49.6% of women with CVD; 59.8% of women with diabetes without known ASCVD; 42.3% of women with an LDL ≥190 mg/dL; and 19.9% of women with an ASCVD risk ≥7.5%. Rates of statin use were 43.8% for women with ≥ two prior ASCVD events and 69.4% for women with ≥ one prior ASCVD event plus multiple high‐risk conditions. Among women eligible for statins, Black women had a significantly reduced adjusted odds of being on a statin (OR 0.53, 95% confidence interval [CI] 0.36‐0.78) compared with White women.ConclusionsIn this cohort of multiethnic women, rates of statin use among women who would benefit were low, with Black women having lower odds of statin use than White women.     

Drug-induced cutaneous lupus erythematosus: 88 new cases

Background

An increasing number of drugs have been linked to drug-induced subacute cutaneous lupus erythematosus (DI-SCLE). The recognition and management of DI-SCLE can be challenging, as the condition may be triggered by different classes of drugs after variable lengths of time.

Objectives

To determine the proportion of patients with cutaneous lupus erythematosus (CLE) whose drugs are an inducing or aggravating factor.

Materials & methods

We conducted a retrospective chart review of patients diagnosed with CLE at a dermatological department over a 21-year period. We registered clinical, serological, and histological data with a focus on drug intake.

Results

Of 775 consecutive patients with a diagnosis of lupus erythematosus (LE) or suspected LE, a diagnosis of CLE could be confirmed in 448 patients. A total of 130 patients had a drug intake that could suggest DI-SCLE. In 88 cases, a drugwas evaluated to be definitely, probably, or possibly triggering CLE using the Naranjo probability scale. The most common drugs involved were proton pump inhibitors (PPIs), thiazide diuretics, antifungals, chemotherapeutics, statins, and antiepileptics. The incubation period varied widely with a median of eight weeks. The characteristics of DI-SCLE patients were more widespread rash relative to the other patients, with inflamed skin lesions or atypical variants which could resemble erythema multiforme.

Conclusions

We present 88 patients with DI-SCLE, which is the largest case series reported, to date. DISCLE represented 20% of patients with CLE seen at our department.We conclude that DI-SCLE should be considered in every case of SCLE.
