Treatment of renal stones with flexible ureteroscopy in preschool age children

The aim of the study is to evaluate the efficacy and safety of retrograde intrarenal surgery (RIRS) to treat renal stones in preschool age (<7 years) children. From September 2005 to May 2013, a total of 65 children (31 boys and 34 girls) with 72 renal stones were treated using RIRS. Patients were considered stone-free when the absence of residual fragments was observed on imaging studies. In the presence of residual calculi >4 mm, a second-stage RIRS was performed. The pre-operative, operative and post-operative data of the patients were retrospectively analyzed. A total of 65 patients with a mean age of 4.31 ± 1.99 years (6 months–7 years) were included in the present study. The mean stone size was 14.66 ± 6.12 mm (7–30 mm). The mean operative time was 46.47 ± 18.27 min. In 5 (7.69 %) patients, the initial procedure failed to reach the renal collecting system and ended with the insertion of a pigtail stent. The stone-free rates were 83.07 and 92.3 % after the first and second procedures, respectively. Complications were observed in 18 (27.7 %) patients and classified according to the Clavien system. Post-operative hematuria (Clavien I) occurred in 6 (9.2 %) patients, post-operative urinary tract infection with fever (Clavien II) was observed in 10 (15.4 %) patients, and ureteral wall injury (Clavien III) was noted in 2 (3 %) patients. RIRS is an effective and safe procedure that can be used to manage renal stones in preschool age children.     

Paradox in the cubital tunnel syndrome—frequent involvement of left elbow: first report

Objective

Cubital tunnel syndrome (CuTS) is the second most common compression neuropathy in the arm, but the existence of a compressive cause has not been determined conclusively and the majority of the cases are idiopathic. In this paper, involvement sides of limbs of patients with cubital tunnel syndrome were studied.

Material and methods

Between October 2008 and December 2011, the clinical assessment of consecutive operated patients with cubital tunnel syndrome in Rize Education and Research Hospital were analysed. The diagnosis and severity of syndrome was based on electro-diagnostic study.

Results

This study included 57 consecutive patients with cubital tunnel syndrome (39 men, 18 women; mean age, 44,7 years; range, 23–79 years; mean age, 44,7 years; range, 23–79 years); 31 patients underwent surgical treatment. Involvement was on the right side in 18 and on the left in 39 patients. Severity scores and MCV were statistically significant between sides.

Conclusion

Profound involvement with cubital tunnel was found in left elbow. According to the finding of non-dominant elbow involvement in our study, the exact etiology and ideal management of cubital tunnel syndrome continues to be heavily debated.     

Relationship between plasma apelin level and coronary collateral circulation

Objective

Coronary collaterals play a crucial role during an acute ischemic attack. Angiogenesis has an important role in the formation of coronary collateral vessels. Previously, it was shown that apelin is a potential angiogenetic factor. Thus, we aimed to investigate relationship between plasma apelin levels and coronary collateral circulation in patients with stable coronary artery disease.

Methods

Among patients who underwent coronary angiography with stable angina pectoris, patients with a stenosis of ≥90% were included in our study. Collateral degree was graded according to Rentrop–Cohen classification. Patients with grade 2 or 3 collateral degree were included in good collateral group and patients with grade 0 or 1 collateral degree were included in poor collateral group.

Results

Plasma apelin level was significantly higher in good collateral group (0.69 ± 0.2 vs 0.59 ± 0.2 ng/dl, p < 0.001). Serum nitric oxide levels were similar between two groups. In multivariate regression analysis apelin [6.95 (1.46–33.15), p = 0.015] and presence of total occlusion [4.40 (1.04–18.62), p = 0.044] remained as independent predictors for good coronary collateral development.

Conclusions

Higher plasma apelin level was related to better coronary collateral development. Demonstration of favorable affects of apelin on good collateral development may lead to consider apelin in antiischemic treatment strategies in order to increase collateral development.     

Giant rhinophyma: Excision with coblation assisted surgery

An 83-year-old man presented with an unusually severe case of rhinophyma. Giant rhinopyhma is very rare in literature. The giant lesion was widely excised using sharp surgical incision and coblation assisted surgery. Using direct coblation to the nasal dorsum may cause edema in the surrounding tissue. There was minimal edema in surrounding tissue using this technique. A full thickness-skin graft was applied after excision. Cosmetic and functional postoperative results were satisfactory.KEY WORDS: Coblation, giant, rhinophyma     

The efficiency of Gd‐EOB‐DTPA‐enhanced magnetic resonance cholangiography in living donor liver transplantation: a preliminary study

The aim of this study was to evaluate utility of gadoxetic acid disodium (Gd‐EOB‐DTPA)‐enhanced magnetic resonance cholangiography (MRC) for the detection of biliary complications after living donor liver transplantation (LDLT). A total of 18 patients with suspected biliary complications underwent MRC. T2‐weighted MRC and contrast‐enhanced MRC (CE‐MRC) were used to identify the biliary complications. MRC included routine breath‐hold T2‐weighted MRC using half‐Fourier acquisition single‐shot turbo spin‐echo (HASTE) sequences and Gd‐EOB‐DTPA‐enhanced MRC T1‐weighted volumetric interpolated breath‐hold examination (VIBE) sequences. Before confirming the biliary complications, one observer reviewed the MRC images and the CE‐MRC images separately. The verification procedures and MRC findings were compared, and the sensitivity, specificity, and accuracy of both techniques were calculated for the identification of biliary complications. The observer found six of seven biliary complications using CE‐MRC. The sensitivity was 85.7% and the accuracy was 94.4%. Using MRC alone, sensitivity was 57.1% and accuracy was 55.5%. The accuracy of Gd‐EOB‐DTPA‐enhanced MRC was superior to MRC in locating biliary leaks (p < 0.05). The usage of Gd‐EOB‐DTPA‐enhanced MRC yields information that complements the MRC findings that improve the identification of biliary complications. We recommend the use of MRC in addition to Gd‐EOB‐DTPA‐enhanced MRC to increase the preoperative accuracy when assessing the biliary complications after LDLT.     

Does concomitant vaginal prolapse repair affect the outcomes of the transobturator tape procedure in the long term?

Introduction and hypothesis

Little information is available on the effects of concomitant vaginal prolapse repair on the outcomes of the transobturator tape (TOT) procedure. The purpose of this study is to assess the results and complications of TOT when combined with vaginal prolapse repair with a long-term follow-up.

Methods

We conducted a retrospective cohort study of 232 female patients who underwent the TOT procedure at two institutions. There were two groups: group 1 consisted of patients who had undergone TOT alone and group 2 consisted of patients who had undergone concomitant vaginal prolapse repair. The outcomes were analyzed considering four postoperative parameters: objective cure, subjective cure, resolution of urgency urinary incontinence (UUI), and patient satisfaction. The mean follow-up was 66.3 months (range 60–85).

Results

A total of 117 patients in group 1 and 104 patients in group 2 were documented in this study. The subjective and objective cure rates were 87.17 %, 64.95 % in group 1 and 89.42 %, 68.26 % in group 2. Patient satisfaction rates (visual analog scale [VAS] score ≥80) were 71.79 and 83.65 % in groups 1 and 2 respectively (p?=?0.035). Complications were reported according to the Clavien–Dindo classification with grade I 7.7 %, grade II 69.2 %, grade IIIa 7.7 %, and grade IIIb 15.4 %, and grade I 9.5 %, grade II 47.6 %, grade IIIa 42.8 %, and grade IIIb 0 % in groups 1 and 2 respectively.

Conclusions

Concomitant vaginal prolapse repair with TOT does not have any negative effects on continence outcomes; on the contrary, it increases patient satisfaction.     

Prolonged QT Dispersion in the Infants of Diabetic Mothers

Myocardial hypertrophy and cardiac dysfunction frequently occur in newborns of diabetic mothers. The authors hypothesized that wall hypertrophy or disproportionate left ventricular wall thickness in newborns of diabetic mothers may affect both QT and QTc dispersion. This study aimed to assess whether left ventricular hypertrophy affects the QT variables of infants born to diabetic mothers. This prospective cross-sectional study was conducted with 47 consecutively selected neonates of gestational diabetic mothers and 30 healthy neonates born to healthy mothers. All the subjects were evaluated during the neonatal period. Electrocardiography with echocardiography was performed for the patients and the control subjects. The newborns of the diabetic mothers were classified according to septal thickness as group 1 (16 newborns with septal hypertrophy) or group 2 (31 newborns without septal hypertrophy). The study group consisted of three cohorts: groups 1, 2, and 3 (control group). Both QT and QTc dispersion were computed from a randomly selected beat as well as from an average beat derived from 12 beats included in a 10-s electrocardiography. A total of 16 infants (34 %) had a septal thickness of 6 mm or greater. The left ventricular end-systolic diameter in group 1 was smaller (p = 0.0029) than in groups 2 and 3 (p = 0.003). The interventricular septal thickness at end diastole (IVSTd) and the left ventricular posterior wall thickness at end diastole in group 1 were higher than in of groups 2 and 3. The QT and QTc dispersion intervals were longer in group 1 than in groups 2 and 3 (p < 0.001), and a highly significant positive correlation was detected between IVSTd and QT dispersion (r = 0.514, p = 0.042). Elevated QT and QTc dispersions may be risk factors for the development of arrhythmias in newborns of diabetic mothers. These patients may critically need systematic cardiac screening.
