Nonparasitic splenic cysts are rare clinical lesions of the spleen. The management has entailed partial or total splenectomy via an open approach. Recently, laparoscopic approaches have been developed. In this report,we describe laparoscopic marsupialization of a giant splenic cyst (diameter <15 cm).A 15-year-old Indian child presented with a four and a half year history of mass in upper left quadrant associated with left upper quadrant pain which increased since 2 days. Physical examination revealed a large, nontender left upper quadrant mass with minimal movement on respiration. Computed tomography scan confirmed a cyst arising from the spleen, measuring 20×15 cm suggestive of a primary splenic cyst. Echinococcus and Entamoeba histolytica serologies were negative. Laparoscopic exploration was performed. three liters of brown fluid were aspirated and intraoperative cytology confirmed a nonparasitic cyst. The cyst wall was excised, preserving the spleen. The patient's recovery was uneventful, and he was discharged, tolerating a regular diet on postoperative day 3. At follow-up, the patient was asymptomatic and showed no evidence of recurrence. Non-parasitic splenic cysts are rare lesions. Laparoscopic marsupialization is safe and effective and should be considered the treatment of choice even for giant splenic cyst. [ABSTRACT FROM AUTHOR]

Purpose: The present study was conducted to evaluate the epidemiological characteristics of the Acetabular fractures treated in a level one trauma centre of India. This study is one of the largest to provide first-hand information regarding the demography, fracture patterns, other associated injuries, and the hospital stay of acetabular fractures in India., Method: Patients admitted with the diagnosis of acetabular fractures between January 2013 and November 2019 were retrospectively analyzed in terms of demographic data such as age and sex, mechanism of injury, other associated injuries, and the duration of hospital stay., Results: A total of 305 patients with 313 fractures of the acetabulum were included in the study. Among the 305 patients, 268 (87.8%) were male and 37 (12.1%) were female, with a declining male to female ratio over the years. The mean age was 37.1 ± 13.2 years (range 14-84 years). During the seven years, the mean age of presentation progressively increased. Linear regression showed an increase from 33 to 40 years from 2013 to 2019 (R2 = 0.027). Road traffic injuries were the most common mechanism of injury, contributing to about 77.4% of all cases. Associated injuries were seen in 62% of total cases with multiple system involvement in 26.6% of patients. The most frequent pattern in this epidemiological study was an isolated posterior wall fracture (21.4%) while the isolated anterior wall was the least frequent (0.95%)., Conclusion: Acetabular fractures are increasing in numbers and with increasing knowledge so is their surgical management in our country. It shall be prudent to establish an integrated electronic national trauma registry to maintain complete documentation in all institutions dealing with trauma management to ascertain the changing trends of acetabular fracture patterns in the country over time., Competing Interests: On behalf of all authors, the corresponding author states that there is no conflict of interest to disclose., (© 2020 Delhi Orthopedic Association.

Introduction Repair of a "U" shaped rotator cuff tear tends to create extreme tensile forces at the central part of the rotator cuff margin, causing tensile overload and may result in subsequent failure. We describe our technique of repairing the "U" shaped tear in which margin convergence is done using Ethibond (Ethicon Inc., New Jersey) and a single triple-loaded suture anchor. It results in the reduction of the strain and also allows the repair of seemingly irreparable tears. Patients and method We included 10 patients having a "U" shaped degenerative rotator cuff tear. All patients were assessed preoperatively. The University of California at Los Angeles Shoulder score (UCLA shoulder score) recorded preoperatively and at final follow-up was used to assess functional outcome. Result Out of 10 patients, six were males and four were females. The mean age was 60 years (range 50-70 years). The average follow-up was for 31 months (range 24 - 48 months). The UCLA score increased from an average of 9 preoperatively (range 8 - 12) to an average of 29.6 (range 27 - 31) at the terminal follow-up. The UCLA increased in the postoperative period and was statistically significant (unpaired t-test; p < 0.0001). All patients had good/excellent outcomes (UCLA score > 27). Abduction increased from average 27 degree preoperatively (range 20 degree - 35 degree) to an average 131 degree (range 125 degree - 140 degree) at final follow-up (unpaired t-test; p < 0.0001). Conclusion Our technique of modified margin convergence achieves low tension repair and anatomical footprint reconstruction with good clinical outcomes using a single triple-loaded anchor., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2020, Jain et al.)

The framework ruthenium-containing nickel (NiRu) hydrotalcite (HT)-type materials were prepared by a co-precipitation method for the first time in this study. Fourier-transform infrared spectroscopy and X-ray diffraction analysis revealed the formation of a layered hydrotalcite-type phase. DRUV-Vis and X-ray photoelectron spectroscopic studies revealed the presence of nickel in the +2 and +3 oxidation states along with the presence of ruthenium as Ru 3+ ions. Temperature-programmed desorption studies of the NiRu-HT-type materials indicated a two-stage reduction with a decrease in T max , supporting the presence of Ni 2+ and Ru 3+ in the framework of hydrotalcite. The obtained NiRu-HT-type materials proved to be promising catalysts for the reduction of aromatic nitro compounds in the presence of hydrazine as a hydrogen source under ambient conditions. The NiRu-HT-type material demonstrated enhanced activity and selectivity during the reduction of nitrobenzene and its derivatives due to the synergistic effect of nickel and ruthenium ions., Competing Interests: There are no conflicts to declare., (This journal is © The Royal Society of Chemistry.)
