Comparison of Tissue Elastography With Magnetic Resonance Imaging T2* and Serum Ferritin Quantification in Detecting Liver Iron Overload in Patients With Thalassemia Major.

BACKGROUND & AIMS: We investigated whether tissue elastography (TE) can be used as an alternative to magnetic resonance imaging (MRI) T2* analysis to determine the degree of iron overload in patients with thalassemia major. METHODS: We conducted a prospective study of 154 patients (99 male; mean age, 12 ± 3.6 years) with thalassemia major requiring chronic blood transfusion and on iron chelator therapy. The study was performed at a tertiary hospital in India from January 2015 through June 2015. We performed routine blood sample analyses, measurements of serum levels of ferritin, and TE within 1 month of MRI T2* analysis of the liver. The Spearman correlation test and linear regression analysis were used to evaluate the correlation between TE liver stiffness measurements and R2* MRI results or serum ferritin levels. RESULTS: The subjects' mean total serum levels of bilirubin, alanine aminotransferase, aspartate aminotransferase, and albumin were 1.4 ± 0.6 mg/dL, 65.0 ± 51.8 IU/L, 62.9 ± 44 IU/L, and 4.2 ± 0.2 g/d, respectively. Mean liver stiffness measurement, MRI T2* (3 T), corresponding MRI R2* (3 T), and ferritin values were 8.2 ± 4.4 kPa, 3.18 ± 2.6 milliseconds, 617.3 ± 549 Hz, and 4712 ± 3301 ng/mL, respectively. On the basis of MRI analysis, 67 patients (43.5%) had mild iron overload, 49 patients (31.8%) had moderate iron overload, and 22 patients (14.3%) had severe iron overload. Fibroscan liver stiffness measurements correlated with MRI R2* values (r = 0.85; P < .001). TE results identified the patients with severe, moderate, and mild iron overload with area under the receiver operating characteristic curve values of 94.8%, 84.5%, and 84.7%, respectively. Liver stiffness measurements greater than 13.5, 7.8, and 5.5 kPa identified patients with severe, moderate, and mild iron overload, respectively; the sensitivity and specificity values were 92% and 93% for severe overload, 82% and 82% for moderate overload, and 73% and 75% for mild overload. No correlation was found between TE results and serum level of ferritin (r = 0.19; P = .11). CONCLUSIONS: Results of TE correlate with those from MRI T2* analysis. TE is cheaper and more available than MRI and might be used to estimate hepatic iron overload, especially moderate to severe overload in patients with thalassemia major who require chronic transfusion.

Post Colonoscopy Ischaemic Colitis in a Patient without Risk Factors for Colon Ischemia: A Case Report.

Ischaemic colitis is the most common form of intestinal ischaemia and is more common in the elderly and in the people having risk factors for colonic ischaemia. Colonoscopy procedure itself is a rare cause of ischaemic colitis. Fewer than 20 cases of ischaemic colitis caused by colonoscopy procedure have been reported in the english literature till date. This patient presented to us within hours of routine colonoscopy with rectal bleeding and lower abdominal pain. On repeat colonoscopy, the patient had mucosal oedema and ulcerations in the descending colon and sigmoid colon. Computed tomography of abdomen and biopsy of the involved segment confirmed ischaemic colitis. The patient recovered with conservative management.

Etiology, clinical profile, and outcome of liver disease in pregnancy with predictors of maternal mortality: A prospective study from Western India.

BACKGROUND: The aim of this study is to study the etiology, clinical profile, and prognostic factors related to maternal and fetal health in pregnant patients with liver disease in Western India. METHODS: This study included 103 consecutive pregnant patients with liver dysfunction from August 2013 to July 2015, who underwent regular biochemical tests, viral markers, ultrasound of abdomen, etc. and were followed up for 6 weeks postpartum or until death. RESULTS: Pregnancy-specific causes of liver dysfunction were found in 39 % (40/103) patients. Liver diseases were most frequent in third trimester 69.9 % (72/103). Etiologies in third trimester were viral hepatitis 36.1 % (26/72), pregnancy induced hypertension (PIH) 30.5 % (22/72), intrahepatic cholestasis of pregnancy 11.1 % (8/72), acute fatty liver of pregnancy (2/72), etc. Hepatitis E was the commonest agent among viral hepatitis 71.8 % (28/39). Causes of maternal mortality (n = 25) were hepatitis E 40 % (10/25), PIH 32 % (8/25), and tropical diseases 20 % (5/25). Fetal mortality (n = 31) was 38.7 % (12/31) in hepatitis E. Maternal mortality was significantly associated with presence of jaundice, fever, abdominal pain, oliguria, anemia, leukocytosis, and coagulopathy. Model for end-stage liver disease (MELD) score >21 predicted maternal mortality with 80 % sensitivity and 91 % specificity (area under the receiver operating characteristic curve = 0.878 and p < 0.001). CONCLUSIONS: Liver disease was most common in the third trimester of pregnancy. Hepatitis E was the most common cause of liver disease in pregnant women in western India with significant maternal mortality, predicted by high MELD score.

A Rare Case of Solitary Peutz Jeghers Type Hamartomatous Duodenal Polyp with Dysplasia!

Solitary Peutz Jeghers (SPJ) type hamartomatous polyp is a rare and separate entity from classic Peutz Jeghers syndrome (PJS). A hamartomatous polyp without associated mucocutaneous pigmentations, any other gastrointestinal polyp or a family history of PJS is diagnosed as a SPJ type polyp. We described a case of 22-year-old young man in whom solitary duodenal polyp was incidentally detected and resected. Histopathological examination revealed PJ type hamartomatous polyp with foci of adenomatous and moderate dysplastic change. Very few cases of solitary duodenal PJ type hamartomatous polyps with malignant transformation have been reported. They can be treated with endoscopic or surgical resection. Endoscopic ultrasound can give an idea about the depth of involvement. This is a rare case of duodenal solitary PJ polyp with dysplasia in a young patient.

Esomeprazole induced galactorrhea: a novel side effect.

Proton pump inhibitors (PPIs) are one of the most frequently prescribed medications across the globe. Esomeprazole is the S-isomer of omeprazole, and it is currently the most widely prescribed PPI. The safety profile of esomeprazole is extremely favorable with only minor side effects, like headache and diarrhea, that are encountered in day to day practice. We report a case of a young female with symptoms of gastroesophageal reflux disease who developed galactorrhea after starting esomeprazole therapy. Resolution of galactorrhea after stopping the drug and self-rechallenge by the patient herself with reappearance of galactorrhea confirmed the culprit to be esomeprazole only. We postulate that esomeprazole may have a mild inhibitory effect on CYP3A4, which leads to decreased metabolism of estrogen, thereby increasing serum estrogen levels. Estrogen causes stimulation and production of prolactin release, which results in development of galactorrhea. This is the first case of esomeprazole induced galactorrhea, to the best of our knowledge.

Neurodegeneration with brain iron accumulation--late onset slowly progressive variant.

Neurodegeneration with Brain Iron Accumulation (NBIA) is a rare type of neuroaxonal dystrophy that can be familial or sporadic, characterized by progressive extrapyramidal degeneration. We report a case of 23 year old male who presented with cervical dystonia, dysarthria and MRI brain suggestive of characteristic "eye-of-the-tiger" appearance in the globus pallidus.
