RESUMEN
BACKGROUND: Presence of retro-aortic left renal vein poses special challenge in creating spleno-renal shunt potentially increasing the chance of shunt failure. The technical feasibility and successful outcome of splenectomy with proximal spleno-renal shunt (PSRS) with retro-aortic left renal vein is presented for the first time. The patient was treated for portal hypertension and hypersplenism due to idiopathic extra-hepatic portal vein obstruction. CASE PRESENTATION: A twenty year old male suffering from idiopathic extra-hepatic portal vein obstruction presented with bleeding esophageal varices, portal hypertensive gastropathy, asymptomatic portal biliopathy and symptomatic hypersplenism. As variceal bleeding did not respond to endoscopic and medical treatment, surgical portal decompression was planned. On preoperative contrast enhanced computed tomography retro-aortic left renal vein was detected. Splenectomy with proximal splenorenal shunt with retro-aortic left renal vein was successfully performed by using specific technical steps including adequate mobilisation of retro-aortic left renal vein and per-operative pressure studies. Perioperative course was uneventful and patient is doing well after 3 years of follow up. CONCLUSIONS: PSRS is feasible, safe and effective procedure when done with retro-aortic left renal vein for the treatment of portal hypertension related to extra-hepatic portal vein obstruction provided that attention is given to key technical considerations including pressure studies necessary to ensure effective shunt. Present case provides the first evidence that retro-aortic left renal vein can withstand the extra volume of blood flow through the proximal shunt with effective portal decompression so as to treat all the components of extra-hepatic portal vein obstruction without causing renal venous hypertension.

BACKGROUND/OBJECTIVES: To assess the efficacy and safety of pancreatin (pancrelipase) enteric-coated minimicrospheres (MMS) over a one-year period in patients with pancreatic exocrine insufficiency (PEI) due to chronic pancreatitis (CP). METHODS: This was a 51-week, open-label extension (OLE) of a one-week, multicenter, double-blind, randomized, placebo-controlled trial in India that enrolled patients ≥18 years of age with confirmed PEI due to CP. Patients received pancreatin (Creon(®) 40000 MMS™) at a dose of 80,000 Ph. Eur. lipase units with each of three main meals/day and 40,000 with each of up to three snacks/day. RESULTS: Of 61 patients entering the OLE, 48 completed treatment (nine were lost to follow up, two withdrew consent, one discontinued due to adverse event [acute exacerbation of CP], one protocol violation). There were significant improvements from baseline to end of OLE in mean ± SD coefficient of fat absorption (CFA: 22.7 ± 12.2%), coefficient of nitrogen absorption (CNA: 6.5 ± 7.9%), body weight (4.9 ± 4.9 kg), BMI (1.9 ± 1.9 kg/m(2)), and most nutritional laboratory parameters tested (p ≤ 0.001). Mean daily stool frequency was reduced from 2.8 to 1.6 (p < 0.001). Improvements in clinical symptoms, clinical global impression of disease symptoms, and quality of life were also observed. Treatment-emergent adverse events (TEAEs) were observed in 64% of patients overall. Only 13% of patients experienced TEAEs judged treatment related. CONCLUSIONS: In patients with PEI due to CP, treatment with pancreatin for one year was associated with significant improvements in fat absorption, nitrogen absorption, and nutritional parameters, improvements in clinical symptoms, and a favorable safety and tolerability profile.

Diabetic Retinopathy (DR) is one of the leading causes of blindness in all age groups. Inadequate blood supply to the retina, retinal vascular exudation, and intraocular hemorrhage cause DR. Despite recent advances in the diagnosis and treatment of DR, this complication remains a challenging task for physicians and patients. Hence, a comprehensive and automated technique for DR screening is necessary, which will give early detection of this disease. The proposed work focuses on 16 class classification method using Support Vector Machine (SVM) that predict abnormalities individually or in combination based on the selected class. Our proposed work comprises Gaussian mixture model (GMM), K-means, Maximum a Posteriori (MAP) algorithm, Principal Component Analysis (PCA), Grey level co-occurrence matrix (GLCM), and SVM for disease diagnosis using DR. The proposed method provides an accuracy of 77.3% on DIARETDB1 dataset. We expect this low computational cost will be helpful in the medicine and diagnosis of DR.

We report a 32-year-old who lady when presented with anemia and was detected to have Peutz-Jegher syndrome. She had malignancies of the colon and ovary over a 2-year follow up and was successfully managed. On screening the family two more members were confirmed to have Peutz-Jeghers syndrome and have been put on surveillance.

Triple A syndrome (Allgrove syndrome) is an autosomal recessive disorder consisting of achalasia, alacrima and Addison insufficiency. We report an 11-year-old girl with predominant symptom of achalasia who was diagnosed as Triple A syndrome almost 3 years after initial presentation.

Rumination syndrome is known to exist in infants and mentally retarded adults since long time. In past few years, some reports appeared that showed its existence in adult patients also. It is frequently confused with the intractable vomiting in adults and misdiagnosis leads to delay in appropriate management. We are here describing the case of a female patient with rumination syndrome where specific points in the history delineated the presence of this illness and helped in appropriate management. The patient became symptom free soon after the diagnosis was reached.
