Indian Journal of Pharmaceutical and Biological Research , 2013,
Abstract: The presence of functional hypothalamo-hypophysial neurosecretory system in vertebrates has led to reviseearlier views regarding the hypothalamus-pituitary relationship. The hypothalamo-neurohypophysialsystem which consists of hypothalamic nuclei, their axonal fibres forming tractus preoptico-hypophysesand the neurohypophysis) works as a morphological as well as a physiological connection between thehypothalamus and the pituitary gland. In fishes, fibres from the neurosecretory hypothalamic nucleiterminate in the neurohypophysis, which remains inter digitized with the adenohypophysis and provides avery close association between the neurosecretory fibres and pars intermedia of the pituitary gland forminga neuro-intermediate lobe. Hypothalamo-Neurosecretory complex of Xenentodon cancila consists ofNucleus Pre-opticus (NPO), Nucleus Lateralis Tuberis (NLT) and their axonal tracts. NPO is a pairedstructure situated on either side of the third ventricle anterodorsal to the optic chiasma. NPO is divisibleinto a dorsal Pars Magnocellularis (PMC) consisting of large neurosecretory cells and Pars Parvocellularis(PPC) formed of smaller neurons. Neurons of PMC and PPC contribute beaded axons to formneurohypophysial tract. Herring bodies are seen in the anterior as well as posterior neurohypophysis.

Abstract: From March 2005 till February 2010, we prospectively followed all patients with diffuse duodenal nodular lymphoid hyperplasia (DDNLH). Patients underwent esophagogastroduodenoscopy with targeted biopsies, colonoscopy, and small bowel video capsule endoscopy. Duodenal nodular lesions were graded from 0 to 4 based on their size and density. Patients were screened for celiac sprue (IgA endomysial antibody), immunoglobulin abnormalities (immunoglobulin levels & serum protein electrophoresis), small intestine bacterial overgrowth (lactulose hydrogen breath test), and Helicobacter pylori infection (rapid urease test, and histological examination of gastric biopsies). Patients infected with Helicobacter pylori received sequential antibiotic therapy and eradication of infection was evaluated by 14C urea breath test. Follow up duodenoscopies with biopsies were performed to ascertain resolution of nodular lesions.Forty patients (Males 23, females 17; mean age ± 1SD 35.6 ± 14.6 years) with DDNLH were studied. Patients presented with epigastric pain, vomiting, and weight loss. Esophagogastroduodenoscopy showed diffuse nodular lesions (size varying from 2 to 5 mm or more) of varying grades (mean score ± 1SD 2.70 ± 0.84) involving postbulbar duodenum. Video capsule endoscopies revealed nodular disease exclusively limited to duodenum. None of the patients had immunoglobulin deficiency or small intestine bacterial overgrowth or positive IgA endomysial antibodies. All patients were infected with Helicobacter pylori infection. Sequential antibiotic therapy eradicated Helicobacter pylori infection in 26 patients. Follow up duodenoscopies in these patients showed significant reduction of duodenal nodular lesions score (2.69 ± 0.79 to 1.50 ± 1.10; p < 0.001). Nodular lesions showed complete resolution in 5 patients and significant resolution in remaining 21 patients. Patients with resistant Helicobacter pylori infection showed no significant reduction of nodular lesions score (2.71 ± 0.

Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.47A2007
Abstract:

The goal of this study was to examine potential deficits in working memory capacity for college students that had a diagnosis of ADHD. College students with ADHD may be a particularly vulnerable group of individuals, given that success on academic work required focus and working memory for a variety of problem solving activities. Performance on these assessments involved controlled processing with simultaneous memory load. Both verbal and visual complex span tasks were used to assess working memory. Additionally, students were all administered with the Brown ADD scale in order to examine self-reported issues with distractibility. Results revealed that ADHD students performed significantly lower on the verbal complex span measure of working memory. No differences in reported inattentiveness were found. Findings were discussed in context of varying task demands in working memory and executive function measures.

Case Reports in Surgery , 2012, DOI: 10.1155/2012/572484
Abstract: We report a case of biliary peritonitis caused by gall bladder perforation due to Taenia saginata induced gangrenous cholecystitis. Although parasites are not unusual causes of biliary tract disorders, especially in disease endemic areas, but this is for the first time that Taenia saginata has been reported to cause gall bladder perforation.

Abstract: Background: Budd-chiari syndrome (BCS) is rare disorder, varied in etiology, inconsistent in presentation, unpredictable in progression, and challenging in therapy. Aim of study: The aim of this study is to review experience of Budd-Chiari syndrome at KFSH, Riyadh; over a ten-year period. Methods: In a retrospective study using a computer data search of the medical records from May 1990 to May 2000, 43 patients′ charts suspected of BCS were reviewed. 29 patients were found to have BCS, diagnosed by Doppler ultrasound, venography, MRI, or CT with or without liver biopsy. Findings: Of the 29 patients, 18 were male (62.1%) and I 1 were female (37.9%); mean age was 35.4 (range 17-69 years). Nine patients had Behcet′s disease; seven patients had malignancy (five HCC, one melanoma and one hypernephroma). Eight patients had antiphospholipid syndrome, two patients had no known cause and three (one related to trauma, the other related to protein C deficiency and the third related nephrotic syndrome). Nineteen patients presented acutely with abdominal pain, progressive ascites and hepatomegaly. Ten patients had subacute presentation mimicking cirrhosis of liver. Five patients had web in the intrahepatic IVC or ostium HV and the remaining 24 patients had thrombosis of hepatic veins. Five patients received surgical shunts, three had balloon dilatation of webs, 11 had anticoagulant therapy and seven patients had symptomatic treatment. Eleven patients died, six of them had malignancy, two died while awaiting liver transplantation and three died with fulminant hepatic failure. Fourteen patients are still on follow-up. Conclusion: Budd Chiari syndrome in Saudi Arabia is related to a defined cause in majority of patients (92%). Behcet′s disease is a dominant cause of BCS in Saudi Arabia. This is in contrast to world literature where around 50% of patients are of unknown etiology

Abstract: We report a case of biliary peritonitis caused by gall bladder perforation due to Taenia saginata induced gangrenous cholecystitis. Although parasites are not unusual causes of biliary tract disorders, especially in disease endemic areas, but this is for the first time that Taenia saginata has been reported to cause gall bladder perforation. 1. Introduction Taeniasis is endemic in Southeast Asia. Two species from the genus Taenia are common parasites of humans—the pork tape worm or T. solium and the beef tape worm or T. saginata. Recent studies suggest that the taenia found in Asia is a subspecies of T. saginata and it has been renamed as T. saginata asiatica [1]. Infection is acquired by taking improperly cooked beef or pork. Most cases of taeniasis are asymptomatic and usually complain of passage of proglottids with stools. However, others present with pruritus ani (77%), nausea (46%), abdominal pain (43%), dizziness (42%), increased appetite (30%), and other mild gastrointestinal symptoms [2]. We report a case of a 32-year-old man with biliary peritonitis caused by gall bladder perforation due to Taenia saginata induced gangrenous cholecystitis—a very rare but potentially fatal complication of taeniasis. 2. Case Presentation A 32-year-old unmarried male, smoker, and beef eater from rural Kashmir, India presented to the surgical emergency department of a tertiary care hospital in Srinagar with features of acute abdomen. He had a three-day history of upper abdominal pain of increasing severity, nausea, and bilious vomiting with fever and chills. Previous history was suggestive of chronic acid peptic disorder. Physical examination revealed anicterus, tachycardia, temperature of 38.5°C, tenderness, and guarding in the epigastrium and right hypochondrium. The total leukocyte count was 13.5 × 109/L with a differential count depicting polymorphs77, lymphocytes20, monocytes02, and eosinophils01. The total bilirubin was 12.7?μmol/L, ALP was 197?IU/L, AST was 68?IU/L and ALT was 42?IU/L. Chest and abdominal radiographs (standing/supine) were normal. USG abdomen reported free fluid in Morrison’s pouch. The patient was operated with an impression of a perforated duodenal ulcer. Operative findings showed a severely inflamed gall bladder with patchy necrosis and a perforation in fundus with pericholecystic pus collection. Further exploration was interesting, and to our surprise we extricated an adult tape worm of approximately 1.7?m in length from the gall bladder which was devoid of stones (Figure 1).
