Abdominoscrotal hydrocele with ipsilateral hydroureteronephrosis in an adult: A case report

Abdominoscrotal hydrocele (ASH) is very rare in adults and difficult to suspect on clinical examination. ASH is a very unusual presentation of scrotal hydrocele with extension intra-abdominally through the inguinal canal either communicating to the peritoneal cavity or non-communicating. An ASH is a congenital pathology involving a scrotal hydrocele expanding through the inguinal canal and reaching the abdominal cavity. Here, we present the case of a 25-year-old man admitted with a complaint of pain and lump in the left lower abdomen for 2 months and swelling in the left groin for 2 years. Ultrasound and computed tomography suggest left ASH with left-sided hydroureteronephrosis. A left DJ stent was placed and on exploration, a large cystic mass was seen intraperitoneally extending into the scrotum through the inguinal canal. Excision of the abdominal part and partial excision of the scrotal part were done with eversion of the remaining tunica vaginalis sac. Although ASH is a rare entity, it should always be kept on the list of differential diagnoses during the complaint of large abdominal mass in adults.

Intracardiac Repair in Late Adolescent and Adult Tetralogy of Fallot — Early and Midterm Results from a Tertiary Care Centre

Abstract Introduction: In developing countries like India, it is common for late presentation of Tetralogy of Fallot (TOF) patients to a hospital as compared to that of developed countries. The objective of this study is to analyze the surgical outcome of TOF patients with age > 15 years. Methods: This is a retrospective descriptive study of the surgical outcomes of 45 adult patients undergoing correction for TOF. Epidemiology, symptomology, and preoperative evaluation were performed. Results: Most of the patients were male (33 [73%]). The median age was 21 years. A total of 42 (93.33%) patients had subaortic ventricular septal defect (VSD), while three (6.6%) patients presented with doubly committed VSD. The most common type of right ventricular outflow tract (RVOT) obstruction was combined infundibular and valvular types, accounting for 34 cases (75.5%). Six patients had infundibular RVOT obstruction, while three patients (6.6%) had predominantly valvular pulmonary stenosis. We performed trans-right atrial repair in 33 patients. Right atrium-pulmonary artery approach was used in five patients (11.1%). The most common postoperative complication was right bundle branch block, seen in 14 patients, with a mortality rate of 2% in the early postoperative period. We achieved excellent early and midterm survival results and significant improvement in functions and disease-free quality of life. Conclusion: Intracardiac repair in adult TOF can be performed with low mortality, less residual RVOT obstruction, and need for revision of RVOT far less frequent by using the Jhajhria Infundibular Resection Adequacy Assessment technique (JIRAAT) to assess for adequacy of infundibular resection.

Purification of a protease inhibitor from Dolichos biflorus using immobilized metal affinity chromatography.

Plant protease inhibitors (PIs) are generally small proteins which play key roles in regulation of endogenous proteases and may exhibit antifeedant, antifungal, antitumor and cytokine inducing activities. Dolichos biflorus (horse gram) is an unexploited legume, which is rich in nutrients and also has therapeutic importance. It contains a double-headed PI, which is an anti-nutritional factor. As there is no report available on its simultaneous removal and purification in single step, in this study, a double-headed PI active against both trypsin and chymotrypsin was purified from Dolichos biflorus to ~14-fold with ~84% recovery using an immobilized metal affinity chromatography (IMAC) medium consisting of Zn-alginate beads. The method was single-step, fast, simple, reliable and economical. The purified inhibitor showed a single band on SDS-PAGE corresponding to molecular mass of 16 kDa and was stable over a pH range of 2.0-12.0 and up to a temperature of 100°C for 20 min. The optimum temperature for trypsin and chymotrypsin inhibitor was observed to be 50°C and 37°C, respectively and pH optimum was pH 7.0 and 8.0, respectively. Thus, IMAC using Zn-alginate beads was useful in simultaneous purification and removal of an anti-nutritional factor from horse gram flour in single step. This procedure may also be employed for purification of other plant PIs in one step.

Isolation, purification and characterization of alkali and thermo stable Xylanase from bacillus sp. Ks09.

Nine bacterial strains were isolated using xylan rich media. The bacterial strain KS09 was selected on the basis of qualitative and quantitative test. It was identified as Bacillus sp. via physiological, morphological and biochemical characterization. The xylanase was purified to homogeneity from crude extract of Bacillus sp. KS09 using ammonium sulphate fractioning and CM-Sephadex C-50. The final purification fold was 10.20 with a recovery of 36.18%. The enzyme was optimally active at 50°C, pH 7.0 and stable over a broad pH range of 6.0-11.0. The residual activity at 6.0-11.0 pH was 100% even upto 3 h of incubation. The enzyme showed 75, 70 and 60% thermal stability at 50, 55 and 60°C, respectively after 1 h of incubation. The kinetic parameters (Km 22.59 mM; Vmax 76.93 IU/mL) were estimated using Lineweaver-Burk plot for purified xylanase. The xylanase activity was inhibited by all the metal ions applied. The characteristic studies revealed that xylanase including its cellulase free nature, broad pH stability and temperature stability are particularly suited its industrial applications.

Improved and convenient method of RNA isolation from polyphenols and polysaccharide rich plant tissues.

It has been difficult to extract a good quality total RNA from the plant parts (such as seeds) which contain high levels of phenolic compounds, carbohydrates and other compounds that bind and/or co-precipitate with RNA. A simple, rapid and efficient method for isolating total RNA from polyphenols and polysaccharide rich plant tissues has been developed. Seeds of leguminosae family were chosen for the study. The good quality and high yield of total RNA was achieved with A260/A280 ratio of 1.9. Seeds of three different crops (Cajanus cajan, Dolichos biflorus and Vigna mungo) at different developmental stages were evaluated for total RNA extraction using standardized protocol. Seeds at 21 days after flowering (DAF) gave the best results among others (7 DAF and dry seeds). Quality of isolated RNA from all the three crops was further checked by cDNA synthesis. The extracted RNA was found suitable for further molecular applications such as reverse transcription and cDNA library construction.
