Sympathetic skin responses from postauricular region in Meniere's disease.

OBJECTIVE: To investigate the sympathetic nervous system activity in Meniere's disease (MD) by recording sympathetic skin responses (SSRs) from the postauricular region (PA). METHODS: Twenty-one patients with definite unilateral MD diagnosis and 12 healthy volunteers were studied by evoking right and left PA-SSRs with electrical stimulation of the left median nerve at the wrist in attack and interval periods of MD. Mean latencies and maximum amplitudes were used in statistical analyses. RESULTS: In unilateral definite MD patients, the mean latencies were longer and the maximum amplitudes were smaller on the involved ear side than those on the normal ear side (p<0.01 for both amplitude and latency) and than those from the controls (p<0.01 and p<0.05). In three patients, there was no detectable PA-SSR on the involved ear side while there were SSRs on the healthy side. In four patients, the responses were absent bilaterally during the attack period. CONCLUSIONS: There is a marked asymmetric sympathetic hypofunction in the area of the PA region of the involved ear in MD patients. SIGNIFICANCE: The PA region is a new site for recording sympathetic skin responses. PA-SSR is a useful tool to investigate sympathetic nervous system function in MD patients.     

Outcomes of patients older than 55 years undergoing abdominoplasty after bariatric surgery

BackgroundBariatric surgery has become widely performed for treating patients with morbid obesity, and the age limits are being pushed further and further as the procedure proves safe. After massive weight loss, many of those patients seek body-contouring surgery for excess skin and fat.ObjectivesTo analyze the feasibility and the safety of abdominoplasty in patients older than 55 years old after bariatric surgery.SettingUniversity hospital medical center.MethodsWe performed a retrospective review of prospectively collected data from patients aged older than 55 years who had undergone abdominoplasty following massive weight loss due to a bariatric surgery at a single institution from 2004 to 2017. The data analyzed included age, gender, preoperative body mass index, associated interventions, co-morbidities, and postoperative complications.ResultsWe retrieved records for 104 patients; 85.6% percent of them were female, and the mean age was 60.1 ± 3.9 years old. Of the 104 patients, 21 (20.2%) underwent a sleeve gastrectomy and 77 (74%) underwent a Roux-en-Y gastric bypass. The mean interval between the bariatric surgery and the abdominoplasty was 33.6 ± 26.9 months. The mean preoperative weight and body mass index were 76.1 ± 14.5 kg and 28.9 ± 4.5 kg/m², respectively. A total complication rate of 20% was observed. The only factor significantly associated with postoperative morbidity was the associated procedure (P = .03), when we performed another procedure at the same time as the abdominoplasty. Complications included postoperative bleeding in 5 patients (4.8%), seromas in 5 patients (4.8%), surgical site infections in 12 patients (11.5%), and wound dehiscence or ischemia in 2 patients (1.9%). No mortality occurred.ConclusionAbdominoplasty can be safely performed in carefully selected patients older than 55 years old after weight loss surgery, and does not present increased morbidity or mortality. We recommend that surgeons avoid adding concomitant procedures when possible, to decrease the risk of complications. It is also important to look at the patient’s previous maximum BMI levels, as a higher maximum BMI can predict higher postoperative risks and longer hospital stays.     

A comparison of spiral and conventional computerized tomography methods in diagnosing various laryngeal lesions

Although endoscopic procedures with tissue biopsy are the mainstay in the evaluation of laryngeal lesions, radiological imaging studies remain important. Computerized tomography (CT), magnetic resonance imaging (MRI) and ultrasound (US) are the most reliable methods, especially for deep laryngeal compartments, cartilage, extralaryngeal structures and neck nodes. However, the larynx is a difficult organ for radiological imaging because respiration and swallowing can cause several artifacts and distort image. In this report we studied the role of a spiral CT technique and compared this with conventional CT in 32 patients. We used the Hitachi W950SRBT machine and took both conventional and spiral sections of the larynx and neck in all 32 patients. The scans were taken with a 5-mm table motion and 5-mm section thickness in both studies. In the spiral technique the raw data acquired were used retrospectively for 2-mm and 5-mm reconstructions. Anatomic details, motion artifacts and vascular enhancements were compared by a scoring system. The mean values were then analyzed statistically by the paired t-test. The average examination time was 3 min 18 s for conventional CT and 28 s for spiral CT. Anatomic detail scores were better in the 2-mm section spiral CT studies compared to 5-mm section spiral and conventional CT groups. Motion artifact scores were better in the 2-mm and 5-mm spiral CT groups compared to the 5-mm conventional CT group. Vascular enhancement scores were better in the spiral CT group. Overall, the thinner (2-mm) sections of the spiral CT studies further improved image quality regarding both anatomic details and motion artifacts. Scanning time for spiral CT was very short, motion artifacts were less, and vascular enhancement and anatomic details were better. Volumetric data could also be reconstructed for thinner sections in all planes retrospectively for further evaluation. Our findings showed that spiral CT was a better method than conventional CT for evaluating laryngeal lesions. Received: 4 December 1996 / Accepted: 18 August 1997     

Effect of Pilates training on people with ankylosing spondylitis

The objective of this study was to investigate the effects of Pilates on pain, functional status, and quality of life in patients with ankylosing spondylitis. The study was performed as a randomized, prospective, controlled, and single-blind trial. Fifty-five participants (30 men, 25 women) who were under a regular follow-up protocol in our Rheumatology Clinic with the diagnosis of AS according to the modified New York criteria were included in the study. The participants were randomly assigned into two groups: in group I, Pilates exercise program of 1?h was given by a certified trainer to 30 participants 3 times a week for 12?weeks, and in group II, designed as the control group, 25 participants continued previous standard treatment programs. In groups, pre-(week 0) and post treatment (week 12 and week 24) evaluation was performed by one of the authors who was blind to the group allocation. Primary outcome measure was functional capacity. Evaluation was done using the Bath Ankylosing Spondylitis Functional Index (BASFI). Exploratory outcome measures were Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Metrology Index (BASMI), Chest expansion, and ankylosing spondylitis quality of life (ASQOL) questionnaire. In group I, BASFI showed significant improvement at week 12 (P?=?0.031) and week 24 (P?=?0.007). In group II, this parameter was not found to have significantly changed at week 12 and week 24. Comparison of the groups showed significantly superior results for group I at week 24 (P?=?0.023). We suggest Pilates exercises as an effective and safe method to improve physical capacity in AS patients. Our study is the first clinical study designed to investigate the role of Pilates method in AS treatment. We believe that further research with more participants and longer follow-up periods could help assess the therapeutic value of this popular physical exercise method in AS.
