Lichenoid photodermatitis associated with nimesulide

An 81‐year‐old‐female patient presented with a 2 week history of erythematous to violaceous lichenoid papules and plaques exhibiting a reticulated pattern on the ‘‘V’' area of the chest and dorsal hands. Fine, whitish reticulated networks were present over the surface of many well developed papules. The lesions were sharply demarcated and moderately pruritic ( Fig. 1 ).

Prolidase deficiency

A 32‐year‐old mentally retarded woman was admitted to hospital with recurrent ulcers on her legs, which appeared for the first time at 8 years of age. Apart from recurrent lower respiratory tract infections and chronic otitis media, her personal history was unremarkable. Her parents were second‐degree relatives. The family history showed no similar disease or mental retardation. Physical examination revealed that the patient had an unusual facial appearance, with a high‐arched palate; she had multiple tooth caries ( Fig. 1 ).

Sildenafil Citrate Does Not Alter Ventricular Repolarization Properties: Novel Evidence from Dynamic QT Analysis

Background: Sildenafil citrate may have direct cardiac electrophysiological effects, and is possibly responsible for some cardiac events. The aim of our study was to investigate the effects of sildenafil citrate on QT dynamicity properties with a new QT analysis program showing even small changes in ventricular repolarization. Methods: Twenty‐four‐hour Holter electrocardiographic recordings were used to obtain the data in the predrug phase (1‐hour rest position before drug administration), and in the postdrug phase (1‐hour rest position, which began 60 minutes after 50 mg oral sildenafil citrate administration). With the special QT analysis program (Verda, Reynolds Medical Ltd., UK); mean values of RR, QT, QT_o (corrected QT), J (the exponent of correction formula) and S (QT/RR plots slope) parameters together with QT variability indexes (QTVI) were calculated for study phases. Results: Mean ± SEM values for RR and QT were higher in postdrug phase than in predrug phase (RR: 845 ± 42 ms vs 816 ± 46 ms, P < 0.05; QT: 371 ± 8 ms vs 361 ± 9 ms, P < 0.05). However, sildenafil did not induce any significant change in mean ± SEM values for QT_o, J, and S in postdrug phase compared with predrug phase (408 ± 10 ms vs 406 ± 8 ms, 0.474 ± 0.030 vs 0.433 ± 0.025, 0221 ± 0.020 vs 0.198 ± 0.017, respectively; P > 0.05). QTVIs were also not different in each phase (predrug: ?0.874 ± 0.071 vs postdrug: ?0.997 ± 0.067, P = 0.109). Conclusions: Fifty milligrams sildenafil does not affect QT dynamicity properties. The cardiac events associated with sildenafil could not be explained with ventricular arrhythmias.     

A multicenter experience of thrombotic microangiopathies in Turkey: The Turkish Hematology Research and Education Group (ThREG)-TMA01 study

Thrombotic microangiopathies (TMAs) are rare, but life-threatening disorders characterized by microangiopathic hemolytic anemia and thrombocytopenia (MAHAT) associated with multiorgan dysfunction as a result of microvascular thrombosis and tissue ischemia. The differentiation of the etiology is of utmost importance as the pathophysiological basis will dictate the choice of appropriate treatment.We retrospectively evaluated 154 (99 females and 55 males) patients who received therapeutic plasma exchange (TPE) due to a presumptive diagnosis of TMA, who had serum ADAMTS13 activity/anti-ADAMTS13 antibody analysis at the time of hospital admission. The median age of the study cohort was 36 (14-84). 67 (43.5%), 32 (20.8%), 27 (17.5%) and 28 (18.2%) patients were diagnosed as thrombotic thrombocytopenic purpura (TTP), infection/complement-associated hemolytic uremic syndrome (IA/CA-HUS), secondary TMA and TMA-not otherwise specified (TMA-NOS), respectively. Patients received a median of 18 (1­75) plasma volume exchanges for 14 (153) days. 81 (52.6%) patients received concomitant steroid therapy with TPE. Treatment responses could be evaluated in 137 patients. 90 patients (65.7%) achieved clinical remission following TPE, while 47 (34.3%) patients had non-responsive disease. 25 (18.2%) non-responsive patients died during follow-up. Our study present real-life data on the distribution and follow-up of patients with TMAs who were referred to therapeutic apheresis centers for the application of TPE.     

The effects of connective tissue manipulation and Kinesio Taping on chronic constipation in children with cerebral palsy: a randomized controlled trial

Purpose: The aim of this study was to investigate the effects of connective tissue manipulation (CTM) and Kinesio Taping^® (KT) on constipation and quality of life in children with cerebral palsy (CP).

Method: This study was designed as a randomized controlled trial. Forty children diagnosed with chronic constipation based on Rome III criteria were randomly assigned to CTM group [6 females, 7 males; 8 y 6?mo (SD = 3y 4?mo)], KT group [7 female, 7 male; 8y 7?mo (SD =3y 5?mo)] or control group [6 female, 7 male; 8y 3?mo (SD = 3y 6?mo)]. All patients were assessed with 7-day bowel diaries, Bristol Stool Form Scale (BSFS), Visual Analog Scale (VAS), and Pediatric Quality of Life Inventory (PEDsQL). Kruskal-Wallis, Wilcoxon’s signed-rank, and Mann–Whitney U tests were used to determine intra-group and inter-group differences. The level of significance was p?Results: Among the CTM, KT, and control groups, there were statistically significant differences regarding the changes in defecation frequency (2.46, 3.00, 0.30, ES 1.16, p?p?=?0.003), BSFS (1.84, 2.14, 0.07, ES 0.91, p?p?p?Conclusions: This study revealed that CTM and KT seem equally effective physiotherapy approaches for the treatment of pediatric constipation and these approaches may be added to bowel rehabilitation program.

• Implications for rehabilitation

• CTM and KT have similar effectiveness in alleviating the constipation-related symptoms and improving quality of life in children with CP.

• CTM and KT can be integrated into bowel rehabilitation programs.

• Considering the characteristics of patients, these treatment options can be used as an alternative of each other by physiotherapists.

     

Evaluation of effects of T and N type calcium channel blockers on the electroencephalogram recordings in Wistar Albino Glaxo/Rij rats,an absence epilepsy model

Objectives:It is suggested that excessive calcium entry into neurons is the main triggering event in the initiation of epileptic discharges. We aimed to investigate the role of T and N type calcium channels in absence epilepsy experimental model.Results:Beta and delta recording ratios in 1 μM/5 μl mibefradil group was significantly different from basal and other dose-injected groups. Beta, alpha, and theta recordings in 0.2 μM/5 μl w-Conotoxin MVIIA group was significantly different from basal and other dose-injected groups. In w-Conotoxin MVIIA after mibefradil group, beta, alpha, and theta recording ratios were significantly different from basal and mibefradil group. Mibefradil and w-Conotoxin MVIIA significantly decreased the frequency and duration of SWDs. The decrease of frequency and duration of SWDs in mibefradil group was significantly different from w-Conotoxin MVIIA group. The frequency and duration of SWDs significantly decreased in w-Conotoxin MVIIA after mibefradil group compared with basal, mibefradil, and w-Conotoxin MVIIA groups.Conclusions:We concluded that both T and L type calcium channels play activator roles in SWDs and have positive effects on frequency and duration of these discharges. These results are related with their central effects more than peripheral effects.KEY WORDS: Epilepsy, mibefradil, T and N type calcium channels, Wistar Albino Glaxo/Rij rats, w-Conotoxin MVIIA
