Comparison of CT-guided sclerotherapy with using 95% ethanol and 20% hypertonic saline for managing simple renal cyst.

OBJECTIVE: We wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts. MATERIALS AND METHODS: A prospective series of 74 consecutive patients (average age: 57.6 +/- 8.1 years) with simple renal cysts were enrolled in this study. They were randomized into two groups and 95% ethanol or 20% HS, respectively, corresponding to 25% of the aspiration volume, was injected. Treatment success was determined six months later with follow-up clinical evaluation and performing ultrasonography. RESULTS: The sclerotherapy was accepted as technically successful without major complications in all except two patients who were excluded because of a communication between the simple renal cyst and the pelvicalyceal collecting system. Thirty-six patients in the ethanol group received sclerotherapy with 95% ethanol and 36 patients in the HS group underwent sclerotherapy with 20% HS. The complete regression ratio of the ethanol group was significantly higher (94% versus 72%, respectively) than that of the HS group. There was one patient with partial regression in each group. The failure ratio of the ethanol group was significantly lower (3% versus 25%, respectively) than that of the HS group. CONCLUSION: Ethanol sclerotherapy under CT guidance is a successful and safe procedure and it can be used for the treatment of simple renal cysts. Sclerotherapy with 95% ethanol is more effective than 20% HS sclerotherapy. Sclerotherapy with HS may be an option for patients preferring to undergo a less painful treatment procedure.     

Cardiac involvement in childhood polyarteritis nodosa

In this report, we evaluated the cardiac findings of 15 children with polyarteritis nodosa. The age range of the patients was 4–14 years; with a mean of 10 years. All have had systemic involvement of the disease. The most common findings in cardiac evaluation were diminished left ventricular systolic functions and mild mitral and/or tricuspid valve regurgitation. One patient had pericardial thickening with no effusion. One had sinus tachycardia. There were no signs of myocardial infarction or ischemia clinically or electrocardiographically. In conclusion, we did not find cardiac complications, such as pericarditis or myocardial infarction, to be as frequent as in previous reports. However, even in asymptomatic patients, systolic dysfunction or valvular involvement were common findings in patients with polyarteritis nodosa, which were not reported previously. These findings may be due to the histological changes of the myocardium or atrioventricular valves. Although these were not severe and fatal lesions, long-term follow-up of these patients with echocardiography may help to determine the course of cardiac involvement.     

Prostatic adenocarcinoma metastasis in the thyroid gland

Metastasis from prostate to thyroid gland is very uncommon. Here we report a 77-year-old man who was admitted to the hospital because of a nodular goiter. A fine-needle aspiration biopsy of the nodule showed metastatic prostatic adenocarcinoma. This is the second case of a metastatic prostate carcinoma to the thyroid gland.     

Susac's syndrome: A case of simultaneous development of all three components of the triad

Susac's syndrome is characterized by the clinical triad of encephalopathy, branch retinal artery occlusions and sensorineural hearing loss. We here report a case of 46 year old woman with a sudden diminution in visual acuity at the left eye, headache and decreased hearing at the right ear with mild confusion considered as Susac's syndrome with complete triad. Although it's a relatively rare entity, it should be kept in mind in differential diagnosis of the neurological disorders, especially in women in 20- to 40-year of age presenting with acute hearing loss.     

The evaluation of renal hemodynamics changes in Familial Mediterranean fever with color Doppler sonography

Background: Renal resistive index (RRI) scanned through renal Doppler is a practical marker employed in measuring blood flow in renal and intrarenal arteries and in noninvasive evaluation of renal vascular resistance. We aimed to investigate the renal hemodynamic variations in patients with Familial Mediterranean Fever (FMF).

Material and methods: Seventy-nine FMF patients and 51 healthy subjects suitable for age and sex were included. Patients were divided into two groups according to their urinary albumin excretion. Fifty-two patients with 0–29?mg/day albuminuria were included in the normoalbuminuric group while 27 patients with 30–299?mg/day albuminuria were included in the microalbuminuric group.

Results: RRI values were higher in patients with FMF compared to the healthy subjects (p?p?=?0.002, p?p?=?0.013.

Conclusion: RRI may be a marker that may be used in assessing resistance to renal blood flow, early renal damage, and progression of renal damage in FMF patients.     

Phylogenetic and recombination analysis of the homing protein domain of grapevine fanleaf virus (GFLV) isolates associated with ‘yellow mosaic’ and ‘infectious malformation’ syndromes in grapevine

The RNA2 of seven grapevine fanleaf virus (GFLV) isolates from vines with yellow mosaic (YM) symptoms from different origin were sequenced. These sequences showed a high variability in the homing protein (2A^HP) and, in five of them, a putative recombination with arabis mosaic virus (ArMV) was detected. To investigate recombination frequency, the partial sequences of the 2A^HP of 28 additional GFLV isolates from nine different countries, showing either YM or infectious malformations (MF) symptoms, were obtained and compared with those of GFLV isolates from GenBank. The analysis confirmed the high level of sequence variability (up to 41 % at the nucleotide level) among isolates. In phylogenetic trees constructed using different approaches, the sequenced isolates always clustered in four conserved groups, three of which comprised YM strains (groups 1, 2 and 3), and one (group 4) the MF strains. Potential interspecific recombination sites between GFLV and ArMV were predicted in the 2A^HP gene of several isolates, all of which were associated with YM symptoms.     

Efficacy of vaginal misoprostol before hysteroscopy for cervical priming in patients who have undergone cesarean section and no vaginal deliveries

We wanted to investigate the effect of misoprostol administered vaginally before operative hysteroscopy on cervical dilation, complications, and failure rates in patients who have undergone cesarean section and who have never delivered vaginally. Sixty patients who had undergone cesarean section, who had never delivered vaginally before, and were about to undergo hysteroscopy for various intrauterine lesions were included in this randomized controlled study. Thirty-two patients in the study group were given misoprostol 400 microg, and 28 patients in the control group were given placebo (hexetidine pill) vaginally twice, 6 and 12 hours before the procedure. Primary endpoints were cervical width detected with Hegar dilators and complication and failure rates. Mean cervical width was greater in patients in the study group (6.5 +/- 0.8) than it was in patients in the control group (3.0 +/- 0.6), (p = .0001). Complication and failure rates were lower in patients in the study group (p = .01). Administration of vaginal misoprostol before hysteroscopy proved to be effective in cervical ripening and in reducing complication and failure rates.     

Low Dose Ketoconazole is an Effective and a Relatively Safe Alternative in the Treatment of Hirsutism*

Summary: Efficacy, clinical and hormonal effect of ketoconazole in 400 mg/day dose was tested in a prospectively-designed study. Twenty four patients with hirsutism according to the Ferriman and Gallwey score (>8) and elevated blood androgen levels were administered 400 mg/day ketoconazole for 6 months. Basal and posttherapy early follicular phase androgens and biochemical parameters were evaluated. In 22 patients significant improvement and in 2 slight improvement was seen in subjective complaints. No side-effects were observed in these patients other than 2 cases of pruritus (transient), 2 mild gastric upset and 1 mastodynia. All patients completed the study. Low dose ketoconazole seems to be effective in the treatment of hirsutism with relatively few side-effects but still should be reserved as an alternative choice due to the potential for deleterious hepatic effects.     

Nephropathy and retinopathy in type 2 diabetic patients living at moderately high altitude and sea level

BACKGROUND: High-altitude-induced hypoxia results in various diseases, such as chronic mountain sickness and high altitude retinal edema, and may affect severity and incidence of some cardiovascular diseases. In order to evaluate the effects of moderately high altitude on diabetic nephropathy and retinopathy, a cross-sectional study was planned. MATERIAL METHOD: Long-term type II diabetic residents of sea level (n=75, 38 male, 37 female, mean age 51.9+/-10.5 in Trabzon and Zonguldak cities) and moderately high altitude (h = 1,727 m, n = 73, 28 male, 45 female, mean age 48.3+/-12.1, Van city) were compared. RESULTS: No difference was observed in terms of age, gender, diabetes duration, body mass index, smoking, systolic, diastolic, and mean arterial blood pressure values, serum glucose levels, cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, hemoglobin, HbA1C, hypertension control, or blood pressure medications and retinopathy incidence. Mean 24 h protein excretion (210.0+/-139.9, 127.8+/-112.1 mg; P=0.00), proteinuria prevalence (57.5% versus 33.3%, p=0.003), and serum creatinine levels (1.04+/-0.22 versus 0.84+/-0.21, p = 0.00) were significantly higher in the highlanders, glomerular filtration rate (GFR) was significantly lower in sea level (SL) patients (90.9+/-26.5 versus 83+/-21.1, p=0.05). CONCLUSION: Tendency to diabetic nephropathy as indicated by higher proteinuria and creatinine levels is increased among type 2 diabetic patients living at moderately high altitude. Prospective studies are needed to confirm these findings.
