RESUMO

Purpose Acute lower extremity ischemia is still a main cause of mortality and morbidity in orthopedic traumatology and reconstructive surgery. In acute lower extremity ischemia, the skeletal muscles are the tissues that are the most vulnerable to ischemia. The aim of this study was to evaluate the effects of iloprost (IL) therapy on skeletal muscle contractile impairment and mitochondrial degeneration in an acute lower extremity ischemia-reperfusion rat model. Main Methods Forty Wistar albino rats were randomly divided into a control group and four experimental groups. Experimental groups were either subjected to 2 h of lower extremity ischemia followed by a 4-h reperfusion period or to 4 h of ischemia followed by an 8-h reperfusion period. Except for the animals in the control group, all animals received IL (1 ng/kg/min) or saline (1 ml/kg) by intraperitoneal infusion for 10 min immediately before reperfusion. At the end of the recording of skeletal muscle electrical activity and contractility, all rats were sacrificed by decapitation and muscle samples of lower extremity were immediately harvested for histopathologic analyses. Results After ischemia-reperfusion, a breakdown in the force-frequency curves of extensor digitorum longus muscle was observed, showing the diminished muscle contractility. However, IL significantly improved muscle contractility following injury induced by 2 h of ischemia followed by a 4-h reperfusion period. In addition, IL partially ameliorated mitochondrial degeneration in the muscle cells of ischemia groups. Conclusion This study indicates that immediate IL therapy repairs muscle damage especially after 2 h of ischemia and 4 h of reperfusion and therefore that IL improves contractile function.

RESUMO

Objective. The risk of atherosclerotic heart disease is increased in autoimmune thyroiditis, although the reason is not clear. Lipoprotein(a) (Lp(a)) excess has been identified as a powerful predictor of premature atherosclerotic vascular diseases. The aim of this study is to investigate the relationship between Lp(a) levels and thyroid hormones in Hashimoto patients. Method. 154 premenopausal female Hashimoto patients (48 patients with overthypothyroid (OH), 50 patients with subclinical hypothyroid (SH), and 56 patients with euthyroid Hashimoto to (EH)) were enrolled in this study. The control group consists of 50 age matched volunteers. In every group, thyroid function tests and lipid parameters with Lp(a) were measured. Lp(a) excess was defined as Lp(a) > 30 mg/dL. Results. Total-C, LDL-C, TG, and Lp(a) levels were increased in Hashimoto group. Total-C, LDL-C, and TG levels were higher in SH group than in the control group. Total-C and LDL-C levels were also higher in EH group compared to controls. Lp(a) levels were similar in SH and EH groups with controls. However, excess Lp(a) was more common in subclinical hypothyroid and euthyroid Hashimoto group than in the control group. Conclusion. The Total-C and LDL-C levels and excess Lp(a) were higher even in euthyroid Hashimoto patients. Thyroid autoimmunity may have some effect on Lp(a) and lipid metabolism.

RESUMO

PURPOSE: To reveal the variety of symptoms experienced by patients before acromegaly diagnosis and to emphasize unneeded surgeries that patients undergo related to acromegaly prior to diagnosis of the disease. METHODS: In total, 490 consecutive adult patients with acromegaly who were treated at our institution between 1998 and 2014 were included in this cross-sectional study, of which 313 could be contacted. Participants were questioned about their complaints at initial consultation and at the time of diagnosis, the first medical professional who they consulted, interval between onset and diagnosis, and surgeries they had undergone. RESULTS: This study included 313 participants, of whom 181 were women. The mean age was 48.8 ± 12.0 years. Patients most frequently presented with acral growth of hands and feet (32.6%) and headache (26.2%). Internists were the medical specialists who were most frequently first consulted (29.4%) then neurosurgeons (11.8%). Acromegaly was generally diagnosed by endocrinologists (55%), followed by neurosurgeons (23%). The median elapsed period prior to diagnosis was 24 months, interquartile range 6.0-48.0 months. Some 45.7% had undergone surgery; 35.2% were related to acromegaly symptoms: head and throat surgery (12.8%), nose surgery (9.3%), thyroidectomy (6.4%), carpal tunnel surgery (4.8%). The delay period for patients who had an operation prior to acromegaly diagnosis was significantly longer than for those who had no operations (p < 0.001). CONCLUSIONS: Acromegaly patients mostly present to internal medicine professionals. Surgeries related to acromegaly complications and symptoms before diagnosis cause a long delay period before diagnosis. Medical staff must be more aware of the clinical aspects of acromegaly.

RESUMO

AIM: The aim of this study was to investigate depression and sexual dysfunction in female patients with mucocutaneous Behçet's disease (BD). METHODS: Twenty-five consecutive, sexually active premenopausal female patients with mucocutaneous BD (mean age: 34.76 ± 4.61 SD years) followed at a rheumatology outpatient clinic were enrolled into the study. The control group consisted of 27 age-matched (mean age: 37.0 ± 4.6 SD years), sexually active, healthy volunteers. The Female Sexual Function Index (FSFI) and Beck Depression Inventory (BDI) were used for sexual and psychiatric assessment. RESULTS: Depression was found in four of 27 (14.8%) in the control group and eight of 25 (32%) in the BD group (P = 0.01). The median total FSFI score for patients with BD was 21.85 (interquartile range [IQR]: 18.25-27.9) and for healthy controls, 27 (IQR 21.5-29.3; P = 0.03). Female sexual dysfunction was diagnosed in 14 of 25 (56%) in the BD group and in 11 of 27 (41%) in the control group (P = 0.27). The pain domain was significantly higher in the BD group at 5.6 (4.4-6.0) than in the control group at 4.4 (3.2-5.5; P = 0.03). None of the other domains (desire, arousal, lubrication, orgasm and satisfaction) of the BD and control groups were different. There were no statistically significant differences between the FSFI, BDI scores and presence of genital ulceration in the BD patients. CONCLUSION: Depression and FSD were more common in the patients with BD than in the healthy subjects. This might have been a result of the depressive effect of chronic disease as well as BD and low androgen levels.
