Incorrect Application Technique of Metered Dose Inhalers by Internal Medicine Residents: Impact of Exposure to a Practical Situation

Background. Several well-controlled studies have proven the clinical benefit of specific immunotherapy (SIT) for seasonal allergic rhinitis (AR). However, whether subcutaneous SIT injection could cause a transient increase in bronchial reactivity (BR) remains unknown. Objective. To investigate whether subcutaneous SIT injection, either during or outside the pollen season, could cause an increase in BR in children with pollen allergy. Methods. Twenty-two children (mean age 13.6 ± 0.7 years) with AR who were receiving maintenance SIT for 15 months were included in the study. Pre-injection BR of the patients was evaluated with methacholine provocation test immediately before maintenance dose of SIT during the peak pollen season and outside the season. The post-injection test was administered 24 hours after SIT injection. Results. There was no difference in FEV₁ measures recorded during [98(93–109)%] and outside [102(96–111)%] the pollen season. There was no significant difference between pre- [64(7–64)mg/mL] and post-allergen injection [32(7.5–64) mg/mL] BR outside the pollen season (p = 0.9). A trend towards improvement following allergen injection [64(5.4–64)] as compared to pre-allergen injection [14.6(3.5–64)] was shown during the pollen season (p = 0.053). Although PC20 measures in the pollen season were lower than outside the season, the difference was not significant. The percentage of the patients with bronchial hyperreactivity was 62% during and 43% outside the season. Conclusion. SIT injections both during and outside the pollen season cause no increase in BR in children with AR. This calls into question the necessity of empirical dose reduction during the pollen season.     

Barbexaclone Abuse in a Cannabis Ex-User

ABSTRACT

Abuse of drugs including addictive ingredients is common among patients with initial addiction history. This article reports a patient who had experienced a panic attack due to cannabis intoxication and has began to abuse an antiepileptic drug barbexaclone after he had quitted cannabis.     

Speckle-tracking echocardiographic imaging of the right ventricular systolic and diastolic parameters in chronic exercise

Morphology and functions of the right ventricle (RV) show differences in the athletes based on whether exercising acutely or chronically. Temporary RV dysfunction occurs during acute exercise. However, RV functions during chronic exercise are speculative. In the present study, we aimed to evaluate RV functions of long-distance runners, who perform chronic exercise, by both conventional and speckle-tracking echocardiography. In this study, we examined 44 long-distance runner and 30 sedentary subjects. RV longitudinal strain (LS), RV systolic longitudinal strain rate (LSRs), RV early diastolic longitudinal strain rate and late diastolic longitudinal strain rate parameters were evaluated by apical 4-chamber gray-scale imaging through the septum and free wall of RV in accordance with automated function imaging protocol. It was observed on the conventional echocardiographic parameters of longdistance runners that RA and RVED diameter have been increased (p = 0.028; p = 0.003 respectively), whereas systolic right ventricle fractional area change and tricuspid annular plane systolic excursion values were similar to those of sedentary subjects (p = 0.65; p = 0.75 respectively). LS and systolic and diastolic strain rate functions were also similar. Morphological adaptation, but not functional change, occurs in the athletes performing chronic exercise.     

Antimicrobial Activities of Fruits of Crataegus. and Pyrus. Species

Abstract

The antimicrobial activity of the ethyl acetate extracts from fruits of Crataegus tanacetifolia., Crataegus x bornmülleri., Pyrus communis. subsp. communis., and Pyrus serikensis. (Rosaceae) were investigated by the agar-well diffusion assay, and the extracts exhibited antimicrobial effect against most of the bacteria and all of the yeasts tested. Although the plants differed in their activities against the microorganisms tested, the extracts of C. x bornmülleri. and P. communis. subsp. communis. displayed no antifungal activity against the fungi tested. P. serikensis. extract inhibited the growth of all bacteria tested but not Aspergillus niger., Aspergillus parasiticus., Aspergillus citri., and Aspergillus fumigatus.. In conclusion, P. serikensis. was the most active antimicrobial plant. Particularly, P. serikensis. extract showed significant antifungal activities and could be used as an antimicrobial agent in new drug therapy.     

Muscle transposition and skin grafting for salvage of below-knee amputation level after bilateral lower extremity thermal injury

Thermal injury to the lower extremity sometimes necessitates amputation around the knee joint. Knee function is so critical to prosthetic rehabilitation that every attempt should be made to salvage the knee joint. This report presents an unusual case of bilateral lower extremity flame burn requiring amputations. While the distal two-thirds of the legs and both feet were totally necrotic, the thermal damage was limited to skin and subcutaneous tissue sparing muscle and bone in the proximal one-third of the legs and posterior thighs. The below-knee amputation level was salvaged by muscle transposition over the anterior tibia and resurfacing of muscle cuffs with thick split-thickness skin grafts. The post-operative period was uneventful. Amputation stumps tolerated the below-knee prosthesis well and the patient attained independent functional prosthetic ambulation at the post-operative fourth month. It is known from the reconstruction of the plantar foot that skin-grafted muscle tissue tolerates weight bearing and shearing forces well. This principle can also be used for salvage aspects of the below-knee amputation level.     

Anatomy,Variants, and Pathologies of the Superior Glenohumeral Ligament: Magnetic Resonance Imaging with Three-Dimensional Volumetric Interpolated Breath-Hold Examination Sequence and Conventional Magnetic Resonance Arthrography

The purpose of this review was to demonstrate magnetic resonance (MR) arthrography findings of anatomy, variants, and pathologic conditions of the superior glenohumeral ligament (SGHL). This review also demonstrates the applicability of a new MR arthrography sequence in the anterosuperior portion of the glenohumeral joint. The SGHL is a very important anatomical structure in the rotator interval that is responsible for stabilizing the long head of the biceps tendon. Therefore, a torn SGHL can result in pain and instability. Observation of the SGHL is difficult when using conventional MR imaging, because the ligament may be poorly visualized. Shoulder MR arthrography is the most accurately established imaging technique for identifying pathologies of the SGHL and associated structures. The use of three dimensional (3D) volumetric interpolated breath-hold examination (VIBE) sequences produces thinner image slices and enables a higher in-plane resolution than conventional MR arthrography sequences. Therefore, shoulder MR arthrography using 3D VIBE sequences may contribute to evaluating of the smaller intraarticular structures such as the SGHL.
