Effect of caffeic acid phenethyl ester on survival of axial pattern flaps in rats with ischaemia-reperfusion injuries.

Oxygen-derived free radicals have been implicated in the pathogenesis of tissue injury after ischaemia-reperfusion. Caffeic acid phenethyl ester (CAPE), an active ingredient of honeybee propolis, has been identified as having potent antioxidant and anti-inflammatory properties. We evaluated the ability of CAPE applied intraperitoneally in reducing tissue injury after ischaemia-reperfusion. To investigate whether treatment with CAPE modifies the concentrations of the endogenous indices of oxidant stress, we examined its effects on a model of flap ischaemia-reperfusion injury in rats. CAPE (10 micromol/kg) was given through the peritoneum before reperfusion. CAPE given intraperitoneally had an inhibitory effect on tissue injury after ischaemia-reperfusion comparable to that of a control group. The anti-inflammatory and antioxidant properties of CAPE may contribute to its suppression of tissue injury.     

Dydrogesterone-induced hepatitis and autoimmune hemolytic anemia.

Dydrogesterone, similar to women's natural progesterone, has been used in a wide range of gynecological conditions. Despite its widespread use, dydrogesterone-induced hepatotoxicity and dydrogesterone-induced hemolytic anemia have, to the best of our knowledge, never been reported previously. We describe a case of hepatitis and warm antibody hemolytic anemia due to dydrogesterone.     

A new syndrome with cardiac malformation,cleft lip-palate,microcephaly and digital anomalies?

A family with cardiac malformation, cleft lip-palate, short stature, microcephaly, distally placed thumbs, short 2nd and 5th fingers, long and broad 1st toes, broad distance between 1st and 2nd toes and mediodorsal curvature of the 4th toes with syndactyly of the 2nd and 3rd toes has been described as having a new syndrome. While some members of the family had full signs of the syndrome, others had similar but fewer and less severe anomalies of the same structures. The presence of common findings in three generations, its variable expressivity and pleiotropism, and the non-consanguineous history in the parents suggest that the inheritance is autosomal dominant.     

The Top 100 Most-Cited Articles on Hallux Valgus

BackgroundTo perform the citation and content analysis of 100 articles on Hallux valgus from the most cited to the least.Materials and methodsArticles published on Hallux valgus between 1980 and 2020 were analyzed by making use of the Web of Science database. Articles were ranked from most cited to the least. Content analysis of all articles was also carried out. Original research articles, reviews, and clinical trials were included in the study whereas case reports were excluded from the study.ResultsThe total number of citations of the 100 most-cited articles was 7,697. The most-cited article was ‘Prevalence of hallux valgus in the general population; systematic review and meta-analysis’ published by Sheere Nix in Journal of Foot and Ankle Research in 2010. The country where the articles were mostly produced was USA (n = 46). The most interesting issue was the osteotomy techniques and changes in Hallux valgus surgery.ConclusionThe treatment of the Hallux valgus disease is still discussed today. Citation analyses have shown that surgical developments related to HV surgery still attract attention, and this information will be updated continuously in line with the increasing number of articles.

Exercise-induced changes in QT interval duration and dispersion in patients with isolated myocardial bridging

BACKGROUND: Isolated myocardial bridging (MB) often is considered to be an unimportant angiographic finding; however, its association with cardiovascular event has been shown. In this study we aimed to assess exercise-induced electrocardiographic (ECG) changes and susceptibility to arrhythmia in patients with MB. METHOD: 21 consecutive patients who had angiographically proven MB (group I) and 25 subjects (group II) who had normal coronary arteries underwent exercise test using Bruce protocol. Before and after the exercise test the changes in QT interval duration and dispersion were compared. RESULTS: Baseline characteristics of both groups were similar. Heart rate significantly increased after exercise test in both groups. In group I, after exercise mean QT(max) and QT(min) durations did not change significantly compared to baseline values, respectively. (QT(max): 411+/-20 vs. 421+/-18 ms, p>0.05 and QT(min): 380+/-12 vs. 378+/-10 ms, p>0.05). However, following exercise test QT dispersion (QT(d)) and corrected QT dispersion (QT(cd)) significantly increased when compared to baseline values, respectively. (34+/-13 vs. 66+/-14 ms, p<0.05 and 37+/-14 vs. 69+/-17 ms, p<0.05) On the other hand, in control group QT(max) and QT(min) durations, QT(c) and QT(cd) did not change significantly compared to baseline values, respectively. (QT(max): 408+/-18 vs. 412+/-17 ms, p>0.05 and QT(min): 390+/-11 vs. 387+/-10 ms, p>0.05; QT(d): 25+/-14 vs. 31+/-16 ms, p>0.05; QT(cd): 27+/-15 vs. 33+/-17 ms, p>0.05). CONCLUSION: Treadmill exercise test significantly increased QT dispersion in patients with MB. This increase may result from exercise-induced ischemia at the area perfused by bridged artery.     

Percutaneous transluminal angioplasty of the inferior right hepatic vein for the treatment of Budd-Chiari syndrome

Budd-Chiari Syndrome is one of the several causes of portal hypertension and is characterised by hepatomegaly, ascites and abdominal pain. The treatment requires either medical or interventional/surgical procedures. A case of Budd-Chiari Syndrome with a membranous web that causes obstruction in the ostium of the inferior right hepatic vein is reported here which was treated by percutaneous transluminal angioplasty (PTA). The patient was asymptomatic and off medication and there was no recurrence after 18-months follow-up.
