SUI in postmenopausal women: advantages of an intraurethral + intravaginal Er:YAG laser.

OBJECTIVE: This study aimed to compare the efficacy of concomitant application of an intraurethral (IU) + intravaginal (IV) non-ablative Erbium (Er):YAG laser with IV application in improving the symptoms of stress urinary incontinence (SUI) in women. METHODS: This observational retrospective cohort study included 122 patients with SUI, 60 women in the IU + IV laser arm and 62 in the IV laser arm. The primary outcome was the International Consultation on Incontinence Questionnaire - Urinary Incontinence Short Form score at entry and at 3, 6 and 12 months from baseline. RESULTS: Demographic characteristics were comparable in both arms. Significant improvement in SUI symptoms was seen 3 months after the intervention and was sustained until the end of month 12 in both arms. The women who had severe SUI symptoms initially showed greater improvement. A higher number of women who initially had mild to moderate SUI symptoms were dry after treatment. Patients treated with IU + IV Er:YAG laser showed significant improvement in SUI symptoms compared to IV laser only, especially at postmenopausal state (p = 0.003). CONCLUSIONS: The Er:YAG laser appears to be an efficient treatment method for SUI. Concomitant application of an IU + IV Er:YAG laser is more effective in relieving SUI symptoms at postmenopausal state.

Greater occipital nerve blockade for the treatment of chronic migraine: a randomized, multicenter, double-blind, and placebo-controlled study.

OBJECTIVES: We aimed to assess the efficacy of greater occipital nerve (GON) blockade at chronic migraine (CM) treatment. MATERIALS AND METHODS: Patients with CM were randomly divided into two groups of 42. GON blockade was administered four times (once per week) with saline in group A or bupivacaine in group B. After 4 weeks of treatment, blinding was removed; in group A, GON blockade was achieved using bupivacaine, while group B continued to receive bupivacaine, and blockade was administered once per month, then followed for 2 months. Primary endpoint was the difference in number of headache days, duration of headache, and pain scores. RESULTS: Seventy-two of 84 patients completed the study. After 1 month of treatment, number of headache days had decreased from 16.9 ± 5.7 to 13.2 ± 6.7 in group A (P = 0.035) and from 18.1 ± 5.3 to 8.8 ± 4.8 in group B (P < 0.001), (P = 0.004, between groups); duration of headache (hour) had decreased from 24.2 ± 13.7 to 21.2 ± 13.4 in group A (P = 0.223) and from 25.9 ± 16.3 to 19.3 ± 11.5 in group B (P < 0.001), (P = 0.767, between groups). VAS score decreased from 8.1 ± 0.9 to 6.7 ± 1.6 in group A (P = 0.002) and from 8.4 ± 1.5 to 5.3 ± 2.1 in group B (P < 0.001), (P = 0.004, between groups). After blinding was removed (in 2nd and 3rd month), group A exhibited similar results like group B in 3rd month. CONCLUSIONS: Our results suggest that GON blockade with bupivacaine was superior to placebo and was found to be effective, safe, and cost-effective for the treatment of CM. According to our knowledge, this is the first randomized, multicentre, double-blind, and placebo-controlled study in the literature in this field of work.

Differentiation of lymphoma versus sarcoidosis in the setting of mediastinal-hilar lymphadenopathy: assessment with diffusion-weighted MR imaging.

OBJECTIVES: To determine the performance of diffusion-weighted magnetic resonance imaging in differentiating lymphoma from sarcoidosis in mediastinal-hilar lymphadenopathy. MATERIALS AND METHODS: Forty-four mediastinal-hilar lymphadenopathy were examined in 27 patients with T1- and T2-weighted conventional images. Then, two diffusion-weighted images were obtained with b = 0 and 1000 s/mm2 values and apparent diffusion coefficients (ADCs) were calculated. The statistical significance of differences between measurements was tested using the Student-t test. RESULTS: The ADC value in the lymphoma group was lower than in the sarcoidosis group, and the difference was statistically significant (p < 0.001). By using the cut-off value of 1.266 x 10(-3) mm2/s, ADC had a sensitivity of 100%, specificity of 81%, positive predictive value of 100%, and negative predictive value of 77% for the differentiation of lymphoma and sarcoidosis. With the cut-off value of 1,97 x 10(-3) mm2/s, ADC had a sensitivity of 50%, specificity of 99.4%, positive predictive value of 68%, and negative predictive value of 91%. CONCLUSIONS: Diffusion-weighted imaging may be useful besides other modalities in differentiating lymphoma from sarcoidosis in mediastinal-hilar lymphadenopathy.

Leiomyoma of the seminal vesicle mimicking tumoral extension of prostatic carcinoma.

Leiomyoma of the seminal vesicle is an extremely rare tumour. The diagnosis of this entity is important when it co-exists with prostatic carcinoma, since it can simulate tumour extension from prostate or bladder cancer on MR imaging and lead to overstaging. In this report, we describe a 74-year-old man with a leiomyoma of the seminal vesicle that mimics tumour extension from co-existent prostatic cancer on T2-weighted MR imaging. To our knowledge, this is the first description of imaging findings of concurrent leiomyoma of the seminal vesicle and prostatic carcinoma.

Clinical significance of basal core promoter and precore mutations in chronic hepatitis B.

BACKGROUND/AIMS: The mutations in the basal core promoter and precore region of hepatitis B virus genome in hepatitis B e antigen-positive and -negative chronic hepatitis B patients have been described. The reports about their prevalence and clinical significance in the Mediterranean region where D is the predominant genotype, are very limited. METHODOLOGY: The serum samples were collected from 44 naive chronic hepatitis B patients. For detection of the mutations basal core promoter and precore regions of HBV genome were amplified and sequenced. RESULTS: All samples were determined as genotype D. Before initiation of treatment basal core promoter mutations were found as 55% (11/20) and 46% (11/24) in HBeAg-positive and -negative patients, respectively (p > 0.5). HBeAg-negative samples were associated with precore mutations (G1896A and G1899A). Three of 20 (15%) patients of HBeAg-positive and seven of 24 (29%) of HBeAg-negative populations showed sustained response to therapy at the 24th month of initiation. CONCLUSIONS: The presence of precore stop codon mutant in those with sustained response was 89%, overall at the end of therapy. At initiation of therapy basal core promoter mutations were more common in non-responders than responders (65% vs. 20%; p < 0.001). While 23% of cases totally showing sustained response, absence of mutations in the basal core promoter region of hepatitis B virus genotype D may be related to sustained response in patients with chronic hepatitis B.

Ex-vivo injection technique for implanting solid pulmonary nodules into porcine lungs for multi-slice CT.

PURPOSE: To develop a method for generating realistic pulmonary nodules that equal small pulmonary metastases and granulomas. MATERIALS AND METHODS: A total of 70 artificial lesions were introduced into 5 inflated porcine lungs inside a dedicated chest phantom by high pressure injection of a fat-wax-Lipiodol mixture and scanned with 16-slice computed tomography (CT). Image evaluation by two experienced radiologists included analysis of morphology, nodule size and density. RESULTS: The median nodule density was 78.8 Hounsfield units (HU), with 54 of 70 nodules (77.14 %) judged typical of small lung metastases. CONCLUSION: Without inducing visible damage of lung parenchyma, the injection technique produces highly realistic pulmonary nodules for morphometry or nodule detection with CT.

C2/C3 nerve blocks and greater occipital nerve block in cervicogenic headache treatment.

In the diagnosis of cervicogenic headache, greater occipital nerve (GON), cervical nerve, minor occipital nerve, and cervical facet joint blocks are used. In our study we compared the GON and C2/C3 nerve blocks in the diagnosis and treatment of cervicogenic headache. In both cases, repeated blocks proved to have a long-lasting effect in the treatment of this disorder, with both GON and C2/C3 blocks being found to be equally effective.

MR Spectroscopy Findings in Lhermitte-Duclos Disease. A Case Report.

Lhermitte-Duclos disease (LDD) is a rare hamartomatous focal or diffuse enlargement of the cerebellum with unclear etiology. The characteristic magnetic resonance imaging (MRI) appearance consists of a non-enhancing mass in the cerebellar hemisphere with a striated pattern. The slow growing behavior of this benign lesion is characteristic. In a few reports on magnetic resonance spectroscopy (MRS) findings in LDD, a decreased level of N-acetyl aspartate, increased level of lactate and near normal level of choline were described. The information obtained from MRS is useful to confirm the relatively benign hamartomatous nature of the lesion. This paper reports a case of LDD and describes the MRI and MRS findings.

Characteristics of headache in migraine without aura and episodic tension-type headache in the Turkish population according to the IHS classification.

We evaluated the characteristics of headache in migraine without aura and episodic tension-type headache diagnosed according to the International Headache Society (IHS) Classification. Fifty migraine without aura and 50 tension-type headache patients were selected prospectively. Fifty-eight percent of migraineurs had pain of a pulsating quality; 88% had severe pain and 74% had unilateral pain; aggravation by routine physical activity was reported by 96%. Episodic tension-type headache was of a pressing quality in 52%, moderate in 40%, bilateral in 82% and aggravated by routine physical activity in 16%. Nausea and/or vomiting, photophobia and phonophobia were reported significantly more commonly in migraineurs than tension-type headache patients.

The effects of etomidate, thiopental, and propofol in induction on hypoperfusion-reperfusion phenomenon during laparoscopic cholecystectomy.

BACKGROUND: A hypoperfusion-reperfusion human model is observed during and soon after laparoscopic surgery. The aim of the study was to research the preventive effects of etomidate, thiopental, and propofol in induction on hypoperfusion- reperfusion phenomenon during laparoscopic cholecystectomy. METHODS: Thirty-six consecutive ASA I-II patients were randomized into three groups of 12 patients each. Anaesthesia was induced with etomidate in group 1, thiopental in group 2, and propofol in group 3. Venous blood samples were obtained at different time points for measurement of plasma malondialdehyde (MDA) levels. Arterial blood and gastric juice samples were obtained for the calculation of gastric intramucosal pH (pHi). Also changes in aminotransferases, alkaline phosphatase and total bilirubin levels were assessed. RESULTS: There was a significant decrease in pHi at 1 min before desufflation (BD) and 20 min after desufflation (AD) compared with before insufflation (BI) in all groups. Plasma level of MDA was significantly increased in group 1 at 1 min BD and 20 min AD compared with before induction of anaesthesia (baseline). Malondialdehyde levels were decreased significantly in group 3 and increased non-significantly in group 2 at the same time points. Also AST and ALT levels were significantly increased in both groups 1 and 2 at 24 h postoperatively. CONCLUSION: Propofol with antioxidant activity may offer many advantages by scavenging reactive oxygen species and their metabolites in case of anticipated hypoperfusion-reperfusion phenomenon, such as would occur in laparoscopic surgery.
