Cervical vestibular evoked myogenic potentials in primary headache disorders

ObjectiveTo determine if cervical vestibular evoked myogenic potentials (cVEMPS) differ in patients with migraine without aura (MoA), vestibular migraine (VM) and tension type headache (TTH).MethodsTwenty patients with MoA, 24 patients with VM and 20 patients with TTH were included in the study. Thirty healthy volunteers of comparable age and gender were taken as the control group. The latencies of peaks p13 and n23, peak-to-peak amplitude of p13–n23 divided by a mean prestimulus EMG recorded during cVEMP testing were measured. The amplitude asymmetry between right and left sides was also calculated and taken into consideration. Caloric testing was conducted to check if the results are associated with the results of the cVEMPs.ResultsFive (one on the right, four on the left side) of the 24 patients with VM (20.8%) displayed a unilateral caloric hypofunction. Normal results were recorded from patients with MoA and TTH. p13, n23 latencies and amplitudes of the patient groups were not statistically different from the results of the healthy controls (p > 0.05). An amplitude asymmetry between right and left sides exceeding that of the healthy controls was not also present (p > 0.05).ConclusionsThough a hypofunctioning horizontal semicircular canal was detected in 20.8% of the patients with VM, saccular function seemed to be unaffected. Patients with MoA and TTH did not display any vestibular test abnormality.SignificancePrimary headache disorders seem to be associated with a normal interictal cVEMP profile.     

Comparison of pain threshold,health and functional status of females with fibromyalgia and multiple sclerosis: a pilot study

Objectives. Fibromyalgia (FM) and multiple sclerosis (MS) are known to cause disability and have an impact on physical functioning, social functioning, and emotional well-being of affected individuals. The aim of this study was to compare pressure pain threshold, health and functional status in females with FM and MS who were ambulatory. Methods. Control point scores (CPS), total myalgic scores (TMS; using an algometer), tender point (TP) counts, and chronic widespread pain were assessed in females with FM and MS and in healthy age-matched female controls. The Fibromyalgia Impact Questionnaire (FIQ), and the Nottingham Health Profile were performed. The Kurtzke Expanded Disability Status Scale (EDSS) was used to estimate the disability status of persons with MS. Results. Fibromyalgia patients have significantly lower CPS and TMS than MS patients and controls. Multiple sclerosis patients had similar CPS but significantly lower TMS compared to controls. Tender point counts were significantly higher in FM than MS patients and controls. Patients with MS had a higher numbers of TPs with respect to controls. Chronic widespread pain was reported by only three patients with MS and these patients did not meet FM criteria for tender point counts. Fibromyalgia patients had significantly lower FIQ-first item scores than MS patients. FM patients had higher NHP section scores in pain, social isolation, emotional reaction, sleep and energy, but similar physical mobility compared to MS patients. In MS patients energy and physical mobility dimension of NHP and FIQ-first item scores correlated with EDSS (r=0.42, P=0.047, r=0.83, P=0.001, and r=0.62, P=0.001, respectively). Conclusion. This cross-sectional study warrants further research comparing FM and MS, which share a lot of clinical and psychosocial features or may coexist. Chronic pain and related fatigue, social and emotional reactions and disability seem to be important components in FM, so taking care of these components, in other words a biopsychosocial model, may improve disease outcome and quality of life not only in FM but also in MS.     

Management of open apices in thirteen traumatized permanent incisors using mineral trioxide aggregate: Case series

AimThe partial pulpotomy can offer a successful outcome for the treatment of traumatic complicated crown fractures. The aim of this clinical report was to evaluate the effect of mineral trioxide aggregate (MTA) in apexogenesis of traumatized immature permanent incisors with pulp exposure.Case reportAccording to clinical and radiological examinations complicated crown fractures and open apices were identified in 13 permanent upper incisors in ten patients (age range 7–10 years). Partial pulpotomy procedures were performed and the teeth were treated with MTA. In this report, periodic clinical and radiological follow-ups were performed. At recall examinations, all teeth were asymptomatic, and clinical and radiological investigations revealed excellent healing patterns with continued apexogenesis.ConclusionRegular examination of immature traumatized permanent teeth is critical for vitality and apexification. In this report, clinical and radiological findings confirm that partial pulpotomy with MTA is a reliable and effective treatment approach in apexogenesis of traumatized immature permanent incisors with pulp exposure.     

Determination of the appropriate catheter length and place for needle thoracostomy by using computed tomography scans of pneumothorax patients

Introduction

The primary goal of this study was to compare the chest wall thicknesses (CWT) at the 2nd intercostal space (ICS) at the mid-clavicular line (MCL) and 5th ICS at the mid-axillary line (MAL) in a population of patients with a CT confirmed pneumothorax (PTX). This result will help physicians to determine the optimum needle thoracostomy (NT) puncture site in patients with a PTX.

Materials and methods

All trauma patients who presented consecutively to A&E over a 12-month period were included. Among all the trauma patients with a chest CT (4204 patients), 160 were included in the final analysis. CWTs were measured at both sides and were compared in all subgroup of patients.

Results

The average CWT for men on the 2nd ICS-MCL was 38 mm and for women was 52 mm; on the other hand, on the 5th ICS-MAL was 33 mm for men and 38 mm for women. On the 2nd ICS-MCL 17% of men and 48% of women; on the 5th ICS-MAL 13% of men and 33% of women would be inaccessible with a routine 5-cm catheter. Patients with trauma, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 2nd ICS-MCL. Patients with trauma, lung contusion, sternum fracture, subcutaneous emphysema and multiple rib fractures would have thicker CWT on the 5th ICS-MAL.

Conclusions

This study confirms that a 5.0-cm catheter would be unlikely to access the pleural space in at least 1/3 of female and 1/10 of male Turkish trauma patients, regardless of the puncture site. If NT is needed, the 5th ICS-MAL is a better option for a puncture site with thinner CWT.
