Minimally Invasive Treatment of Pilonidal Disease: Crystallized Phenol and Laser Depilation

Pilonidal disease has been treated surgically and by various other methods for many years. The most important problem associated with such treatment is recurrence, but cosmetic outcome is another important issue that cannot be ignored. Today, crystallized phenol is recognized as a treatment option associated with good medical and cosmetic outcomes. We hypothesized that the addition of laser depilation to crystallized phenol treatment of pilonidal disease might increase the rate of success, and this study aimed to determine if the hypothesis was true. Patients who were treated with crystallized phenol and 755-nm alexandrite laser depilation were retrospectively analyzed. In total, 42 (31 male and 11 female) patients were treated with crystallized phenol and alexandrite laser depilation and were followed up between January 2009 and January 2012. In all, 38 patients (90.5%) had chronic disease and 4 (9.5%) had recurrent disease. Among the patients, 26 (61.9%) recovered following 1 crystallized phenol treatment, and the remaining patients had complete remission following repeated treatment. Some patients needed multiple treatments, even up to 8 times. None of the patients had a recurrence during a mean 24 months (range, 6–30 months) of follow-up. Whatever method of treatment is used for pilonidal disease, hair cleaning positively affects treatment outcome. The present results support the hypothesis that the addition of laser depilation (which provides more permanent and effective depilation than other methods) to crystallized phenol treatment (a non-radical, minimally invasive method associated with very good cosmetic results) can increase the effectiveness of the treatment and also reduce the recurrence rate of the disease.     

Determination of the mineral content of bee honeys produced in Middle Anatolia

The mineral content of 43 honey samples from the middle regions of Turkey was investigated. Minerals were determined by inductively coupled plasma-atomic emission spectrophotometer. Calcium, potassium, sodium and phosphorus were the most abundant of the elements in all the studied honeys, with average concentrations ranging between 40.13 and 189.69 mg/kg for calcium, 161.01 and 598.62 mg/kg for potassium, 9.34 and 45.9 mg/kg for sodium, and 460.11 and 3,776.96 mg/kg for phosphorus. Cluster analysis of the honey data revealed that the mineral content of Çorum and Konya honeys was closer as they formed a cluster at a similarity level of 60%.     

Application of Rhenium-186 Radiosynovectomy in Elbow Diffuse Pigmented Villonodular Synovitis. - A Case Report with Multiple Joint Involvement

After surgical therapy of diffuse pigmented villonodular synovitis (DPVNS), recurrence is seen in almost half of the patients. The effectiveness of radiosynovectomy (RSV) in preventing recurrence and complaints of DPVNS is well known. Elbow involvement in DPVNS is a very rare condition; therefore, RSV in elbow hasn’t been experienced widely. The aim of this case report is to show the effectiveness of RSV with rhenium-186 (Re-186) sulfide colloid. We applied Re-186 sulfide colloid to the elbow joint of DPVNS patients six weeks after arthroscopic synovectomy. As a result, the patient did not have any complaints, and our findings are compatible with residue or recurrence on magnetic resonance imaging (MRI) in sixth and twentieth month controls after administration. We concluded that Re-186 is an effective adjuvant therapy for the prevention of recurrence and complaints.     

Nutritional composition,microbiological and sensory properties of dried melon: A traditional Turkmen product

Seven different cultivars (Taze vaharman, Gökjek, Arap hatl?, Türkmen vaharman?, Torl? payendeke, Yazk? bi?ek, G?z?l gülab?) of honeydew melons (Cucumis melo L.) from Turkmenistan were processed to a dried traditional product known as ‘kavun kak?’ in order to evaluate the most suitable cultivar for drying process. The chemical composition (dry matter, crude oil, crude protein, crude fibre, energy, ash, water-soluble solids, total sugar, invert sugar, titratable acidity, pH and mineral contents) of the products was determined. The microbiological load (total aerobic bacteria, coliform bacteria and yeasts–moulds) of the samples were also evaluated. There were no significant differences between the odour, taste and texture scores of all the cultivars according to acceptance sensory analysis. The Türkmen Vaharman? and Torl? payendeke samples had the highest colour scores.     

Correlations between Oxidative DNA Damage, Oxidative Stress and Coenzyme Q10 in Patients with Coronary Artery Disease

The correlation of coronary artery disease (CAD) with pro-oxidant/antioxidant balance and oxidative DNA damage was investigated.Seventy-seven patients with CAD and 44 healthy individuals as control were included in this study. The comparative ratios of ubiquinol-10/ubiquinone-10, 8-hydroxy-2^''-deoxyguanosine/deoxyguanosine and the level of MDA measured by HPLC and the activities of GPX and SOD by colorimetric approach in blood samples obtained from patients with CAD were unraveled.8-OHdG/dG ratios, serum MDA level and GPX activity were found significantly elevated level in serum of CAD patients compared to control group. The SOD activity was observed in stable levels in CAD patients. Ubiquinol-10/ubiquinone-10 ratio was significantly lower in patients with CAD than the controls.The positive correlation was observed between 8-OHdG/dG ratios in both MDA levels and GPX activity, while the significant negative correlation was seemed between the ratio of 8-OHdG/dG and ubiquinol-10/ ubiquinone-10 as well as MDA levels and ubiquinol-10/ ubiquinone-10 ratio.We conclude that, both the disruption of pro-oxidant/antioxidant balance and oxidative stress in DNA may play an important role in the pathogenesis of coronary artery disease.     

In vivo effect of losartan on platelet aggregation in patients with hypertension

The angiotensin II receptor, losartan, has been found to inhibit platelet aggregability to some extent in in vitro experiments. There have been conflicting results about the in vivo effects of losartan. We sought to clarify the in vivo effect of losartan on platelet aggregation. Forty patients with grade I essential hypertension were treated with losartan for 3 weeks. Platelet aggregation tests with adenosine diphosphate (ADP) and ristocetin were analyzed and compared before and at the end of the study. Losartan effectively decreased systolic (SBP) and diastolic (DBP) blood pressure. Mean SBP before and after treatment was 159.6 ± 12.8 and 149.2 ± 17.3mmHg, respectively. Mean DBP decreased from 93.7 ± 8.2 to 87.7 ± 10.3mmHg after treatment. The results of the platelet aggregation tests with ADP and ristocetin were not significantly different when both rate and amplitude of maximal aggregation were included. Peak platelet aggregation with ADP regarding the lowest light transmission in the aggregometer was 59.8% ± 24.3% before and 58.3% ± 18.1% after the treatment. The same variables with ristocetin were 66.8% ± 21.6% and 60.8% ± 23.3%, respectively. In vivo effects of losartan on platelet aggregation with ADP and ristocetin were insignificant.     

The effects of hypothyroidism in rats on serum leptin concentrations and leptin mRNA levels in adipose tissue and relationship with body fat composition

Both thyroid hormones and leptin affect sympathetic nervous system activity, basal metabolic rate, body fat mass, food intake, and thermogenesis, and each one also affects the actions of the other. We examined the alterations in serum leptin concentrations and leptin mRNA expression in hypothyroid rats and investigated the relation between serum leptin and leptin mRNA levels with the total adipose tissue mass and total body weight. Twenty male Wistar rats were divided into 2 groups, euthyroid and hypothyroid. Their body compositions were examined by Dual Energy X-ray Absorptiometry at the beginning and end of the study. Serum leptin concentrations and levels of leptin mRNA in the retroperitoneal white adipose tissue were measured at the end of the study. Serum leptin concentrations did not show any difference between the two groups (1.9 +/- 0.2 ng/ml in the hypo and euthyroid group, P > 0.05), but the fat mass of the hypothyroid rats were lower than the euthyroid rats (21.1 +/- 2.5 g in the euthyroid group and 14.2 +/- 1.9 g in the hypothyroid group, P > 0.05 between groups at the end of the study) although the difference between the groups was statistically not significant. Leptin mRNA level was significantly higher in the hypothyroid group than in the euthyroid group (21.6 +/- 1.6 vs. 15.1 +/- 1.2 ng respectively, P = 0.002) although the dissected retroperitoneal fat weight was significantly lower in the hypothyroid group versus the euthyroid group (1.0 +/- 0.2 vs. 1.8 +/- 0.2 g respectively, P = 0.013). In conclusion, the change of leptin mRNA expression in white adipocytes was thought to be the direct result of hypothyroidism or a compensatory response to metabolic changes caused by hypothyroidism.
