Primary renal carcinoid tumor.

Primary renal carcinoid tumor is extremely rare and, therefore, its pathogenesis and prognosis is not well known. We report a primary renal carcinoid in a 26-year-old man treated by radical nephrectomy.

Extrinsic factors promoting insulin producing cell-differentiation and insulin expression enhancement-hope for diabetics.

Diabetes mellitus (DM) is considered to be an autoimmune disorder leading to destruction of beta-cells resulting in to a loss of blood sugar control. Attempts using many pharmacological compositions including exogenous insulin have failed to show tight control of glycemia and associated manifestations. Stem cells are considered a potential tool for the supply of insulin-producing cells (IPC) generation in vitro.

Analgesic efficacy of peritubal infiltration of ropivacaine versus ropivacaine and morphine in percutaneous nephrolithotomy under ultrasonic guidance.

Background And Purpose: Percutaneous nephrolithotomy is a safe and effective endourologic procedure which is less morbid than open surgery. However, pain around a nephrostomy tube requires good post-operative analgesia. We hypothesize that infiltration of local anesthetic with opioid from the renal capsule to the skin around the nephrostomy tract under ultrasonic guidance would alleviate the postoperative pain for a long period.

Randomized double blind trial of intraperitoneal instillation of bupivacaine and morphine for pain relief after laparoscopic gynecological surgeries.

Background: Intraperitoneal injection of anesthetic has been proposed to minimize postoperative pain after laparoscopic surgery. So a randomized, placebo-controlled study was conducted to compare the effectiveness of intraperitoneal bupivacaine with or without morphine for postoperative analgesia after laparoscopic gynecological surgeries.

Methods: A total of 90 ASA I and II female patients scheduled for laparoscopic gynecological procedures were enrolled in the randomized double blind prospective study.

Co-infusion of adipose tissue derived mesenchymal stem cell-differentiated insulin-making cells and haematopoietic cells with renal transplantation: a novel therapy for type 1 diabetes mellitus with end-stage renal disease.

Type 1 diabetes mellitus (T1DM) is a common cause of end-stage renal disease (ESRD). Various factors contribute to wide fluctuations in blood glucose levels and exogenous insulin requirement in such patients even after renal transplantation (RT). Simultaneous pancreas-kidney transplantation is one of the therapies for these patients.

In-vitro generation of human adipose tissue derived insulin secreting cells: up-regulation of Pax-6, Ipf-1 and Isl-1.

We present a study of up-regulation of genes responsible for pancreatic development in glucose-sensitive insulin-secreting mesenchymal stem cells (IS-MSC) generated and differentiated from human adipose tissue (h-AD), with use of our specific differentiation media and without use of any xenogenic material. Anterior wall abdominal fat was collected from 56 volunteers and cultured in self-designed proliferation medium for 10 days. Cells were harvested by trypsinization and differentiated into insulin-expressing cells using self-designed differentiation medium for 3 days followed by evaluation for transcriptional factors Pax-6, Ipf-1, Isl-1, C-peptide and insulin secretion.

Extrinsic factors promoting in vitro differentiation of insulin-secreting cells from human adipose tissue-derived mesenchymal stem cells.

Understanding of β cell regeneration is needed to develop new treatment modalities in diabetes mellitus. We present our experience of glucose-sensitive insulin-secreting mesenchymal stem cells (IS-MSC) generated and differentiated from human adipose tissue (h-AD) with application of specific differentiation media, sans xenogenic material. h-AD from donor abdominal wall was collected in proliferation medium composed of α-Minimum Essential Media, albumin, fibroblast-growth factor and antibiotics, minced, incubated in collagenase I at 37 °C with shaker and centrifuged.

Outcome of deceased donor renal transplantation - a single-center experience from developing country.

Renal transplantation (RTx) is considered as the best therapeutic modality for patient suffering from end-stage renal disease (ESRD). Dearth of donor kidneys is a major problem everywhere, and deceased donor renal transplantation (DDRTx) is seen as at least a partial solution. Even so, DDRTx accounts for only less than 4% of RTx in India.

The effect of stem cell transplantation on immunosuppression in living donor renal transplantation: a clinical trial.

Background/objective: We designed a clinical trial on a group of live-donor renal transplantation (LDRT) patients subjected to pre-transplant stem cell transplantation (SCT) to minimize immunosuppression to low-dose steroid monotherapy.

Methods: LDRT patients subjected to pretransplant SCT who had stable graft function for ≥2 years and serum creatinine (SCr) <2 mg/dL were recruited. Patients with diabetes, hepatitis C/B, rejections, or unwilling to participate, were excluded.

Stem cells versus donor specific transfusions for tolerance induction in living donor renal transplantation: a single-center experience.

Background: We undertook this study to define the role of stem cell transplantation (SCT) versus donor-specific transfusion (DST) in tolerance induction and sustenance in living donor renal transplantation (LDRT).

Methods: In this prospective three-armed trial in LDRT with 13 patients each in demographically well-balanced groups, tolerance induction protocol (TIP) was used with SCT in group 1, DST in group 2, and no induction in group 3. Tolerance induction protocol consisted of SCT/DST under conditioning with bortezomib, methylprednisone, rituximab, and rabbit antithymocyte globulin.

Postrenal transplant Plasmodium vivax malaria: neglected and not benign.

Plasmodium vivax is causing increasingly more cases of severe malaria worldwide. We reported a case of postrenal transplantation acute kidney injury (AKI) associated with P. vivax, a neglected human malaria parasite.

Churg-Strauss syndrome presenting with acute kidney injury in a case of primary focal segmental glomerulosclerosis.

Churg-Strauss syndrome (CSS) also called allergic granulomatosis and angiitis is a multisystem disorder. Churg-Strauss syndrome is defined as an eosinophil-rich, granulomatous inflammation involving the respiratory tract, along with necrotizing vasculitis affecting small- to medium-sized vessels, and is associated with asthma and eosinophilia. Renal involvement in CSS varies from 26 to 88 % but is usually of mild to moderate stage, and advanced renal failure is uncommon.

Postoperative analgesia with epidural opioids after cesarean section: Comparison of sufentanil, morphine and sufentanil-morphine combination.

Background: Epidural analgesia with opioid provides good control of postoperative pain in cesarean section, thereby improving the mother's ability to mobilize and interact with her newborn infant.

Aim: The aim of this study is to evaluate and compare the analgesic actions and side effects of epidural analgesia with sufentanil, morphine or combination of the two after cesarean section.

Materials And Methods: 60 women undergoing elective cesarean section were allocated into three groups of 20 each in a randomized blinded fashion.

Laparoscopic en bloc kidney transplantation.

Laparoscopic donor nephrectomy is well establish procedure and having advantages over open donor nephrectomy in terms of having less pain, early ambulation and rapid post operative recovery. To extend the advantages of laparoscopic surgery to the recipient, recently we have performed laparoscopic kidney transplantations when kidney was procured from deceased donors. As a further extension of the procedure, here we present a case of laparoscopic en bloc kidney transplantation in obese diabetic recipient who received kidneys from 70 year old non-heart beating donor.

Posterior reversible encephalopathy syndrome in setting of postobstructive diuresis and persistent hypocalcemia.

Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiographic entity of heterogenous etiologies, which are grouped together because of similar findings on neuroimaging studies, associated with similar symptom complex of headache, vision loss, altered mentation, and seizures. In this report, we describe a case of PRES in setting of postobstructive diuresis in a 5-year-old male child, whose solitary functioning kidney was obstructed by a 1.6-cm radio-opaque stone, who after percutaneous nephrostomy (PCN) diversion developed persistent hypocalcemia which persisted despite maximum replacement by iv calcium gluconate drip, and the child developed repeated generalized tonic clonic convulsions and became unconscious for 4 days.

An unusual case of Plasmodium vivax malaria monoinfection associated with crescentic glomerulonephritis: a need for vigilance.

Plasmodium vivax infection is increasingly a major public health burden and the second most frequent human malaria. Higher levels of clinical severity and chloroquine resistance are major factors responsible for such increases. Malarial glomerular injury is uncommon and mainly observed in Plasmodium malariae-infected patients.

Ex vivo generation of glucose sensitive insulin secreting mesenchymal stem cells derived from human adipose tissue.

Background: Diabetics are incapable of producing insulin/have autoimmune mechanisms making it ineffective to control glucose secretion. We present a prospective study of glucose-sensitive insulin-secreting mesenchymal stem cells (IS-MSC) generated from human adipose tissue (h-AD) sans xenogenic material.

Materials And Methods: Ten grams h-AD from donor anterior abdominal wall was collected in proliferation medium composed of α-Minimum Essential Media (α-MEM), albumin, fibroblast-growth factor and antibiotics, minced, incubated in collagenase-I at 37°C with shaker and centrifuged.

Medication error: Subarachnoid injection of tranexamic acid.

Some factors have been identified as contributing to medical errors, such as labels, appearance and location of ampoules. We present a case of accidental injection of tranexamic acid instead of Bupivacaine during spinal anaesthesia. One minute after the injection of 3 mL of the solution, the patient developed myoclonus of her lower extremities.

C1q nephropathy with acute hemolytic uremic syndrome.

C1q nephropathy with hemolytic uremic syndrome (HUS) is an uncommon combination associated with rapidly progressive renal failure. We report a case of C1q nephropathy with HUS in an 18-year-old man associated with rapidly progressive renal failure. The patient did not respond to treatment with steroids and was started on maintenance hemodialysis.

Allogenic hematopoietic stem cell transplantation in pemphigus vulgaris: a single-center experience.

Background: Pemphigus vulgaris (PV), an autoimmune disorder characterized by blistering skin/mucus membrane lesions, is mediated by desmoglein-3 autoantibodies. We carried out a prospective clinical trial of hematopoietic stem cell transplantation (HSCT) in thymus, bone marrow (BM) and periphery to reconstitute central and peripheral arms of self-tolerance.

Materials And Methods: Eleven (M:F=5:6) patients with mean age 33.
