Introduction: Urolithiasis is one of the most common urological problems worldwide. The fastest treatment modality to achieve stone clearance of ureteral stones is Ureteroscopic Lithotripsy (URSL). However, it is negated by both the cost burden and potential risk to the patient. Medical Expulsive Therapy (MET) is a treatment option for upto 10 mm stones but has failure rates of 40-60% in the literature. Aim: To analyse the various indications for surgery, whether MET was used or not, if used-its details, operative findings at ureteroscopy including the reason for the failure of MET. Materials and Methods: A cross-sectional study consisting of 72 patients with ureteric calculi undergoing URSL was analysed from June 2017 to December 2018 at Mazumdar Shaw Medical Centre, Bangalore, Karnataka, India. Indications were assessed at the time of admission. During ureteroscopy, factors like impaction, distal obstruction, and unusual findings were studied, which could have contributed to the failure of MET. The Chi-square test was used as a test of significance for categorical data. The Analysis of Variance (ANOVA) test was used as a test of significance to identify the mean difference between continuous variables. The p-value of <0.05 was considered statistically significant. Results: The mean age in the study was 41.65±13.4 years (range 20-69 years), and the mean stone size was 10.03±3.34 mm. Large stone was the most common indication (41, 56.9%, p=0.004), followed by failed MET (35, 48.6%). Even though MET could have been continued for four weeks in 17 patients (23.6%), they were taken up for surgery. The impaction rate was 70.8% (51), with 48.6% (35) being large impacted stones and 22.2% (16) being small impacted stones. The overall stone clearance rate was 68 out of 72 (94.4%). Conclusion: Large stone size (=10 mm) and failed MET were the main indications for surgery. One reason for the failure of MET was not waiting for a duration of four weeks. During ureteroscopy, impaction of the stone, irrespective of size, was the most common finding and was the reason for the failure of MET. Ureteric stones on MET should not be neglected as there are reasons for the failure of MET, and they will require URSL after four weeks. [ABSTRACT FROM AUTHOR]

Introduction: Differentiation between Chronic Hand Eczema (CHE) and Palmoplantar Psoriasis (PP) is a diagnostic challenge. Dermoscopy can helpto distinguish between the two conditions. Aim: To establish and compare the dermoscopic findings of the CHE and PP using DermLite DL4 dermoscope and to confirm the accuracy of the dermoscopic findings with the histopathological findings. Materials and Methods: A cross-sectional study was conducted at Navodaya Medical College, Hospital and Research Centre, Raichur, Karnataka, India, from January 2017 to June 2018. Fifty patients each of CHE (26 male and 24 female subjects) and PP (25 male and 25 female subjects) were included in the study. A detailed clinical history, cutaneous clinical and dermoscopic findings of each case were noted. A 4 mm punch biopsy was taken from 30 patients for histopathological analysis. The data was tabulated, analysed and tested for significance using the Chi-square test. Results: The mean age of the patients was 46±4 years. On dermoscopic examination, diffuse white scales in 45 (90%) patients, over a red background in 49 (98%) patients with regularly arranged dots and globules in 45 (90%) patients was seen in PP. Patchy yellow scales 46 (90%), yellow dots, globules and yellow to brown crusts against a yellow background was seen in all patients (100%) of CHE (p-value <0.001). Histopathological findings are in agreement with dermoscopic findings in 9/16 and 10/14 cases of CHE and PP respectively. Conclusion: Dermoscope is a useful non invasive clinical aid to differentiate between CHE and PP. The presence of diffuse white scales over a red background and regularly arranged vessels indicates PP, whereas the presence of patchily distributed yellow scales, yellow dots and globules; and yellow to brown crusts against a yellow background is more suggestive of CHE.
