Fibroscan and low-density lipoprotein as determinants of severe liver fibrosis in diabetic patients with nonalcoholic fatty liver disease.

BACKGROUND: Fibroscan is an effective and noninvasive tool to quantify fibrosis and steatosis in liver diseases including nonalcoholic fatty liver disease (NAFLD). Type-2-diabetes is a known risk factor for worse prognosis in NAFLD. In this study, we compare liver status in NAFDL diabetic and nondiabetic patients, identify potential risk factors, and determine the usefulness of Fibroscan in this population. PATIENTS AND METHODS: The charts of all patients with NAFLD who underwent Fibroscan at our institution were reviewed. Fibroscan results, demographics, and clinical data were collected and analyzed using SPSS software. RESULTS: Of the 248 NAFLD patients, 73 (29.4%) were diabetic and 175 (70.6%) were nondiabetic. As detected by the NAFLD' liver stiffness measure, 35 (47.94%) diabetic patients had severe liver fibrosis (F4) in contrast to only 46 (26.3%) nondiabetics. Diabetic patients also presented more with hypertension, dyslipidemia, coronary artery disease, and chronic kidney disease. Liver steatosis, liver function tests, and noninvasive scores did not vary significantly between the two groups, except for γ-glutamyltransferase, prothrombin time-international normalized ratio, and BMI-alanine aminotransferase ratio-diabetes score. Diabetic patients had significantly lower high-density lipoproteins and low-density lipoproteins. CONCLUSION: Fibroscan results and low-density lipoprotein are potential diagnostic factors of liver fibrosis in diabetic patients with NAFLD. Further studies are necessary to verify liver fibrosis diagnostic tools and prognostic and genetic markers in diabetic patients.

Median Arcuate Ligament Syndrome: A Single-Center Experience with 23 Patients.

BACKGROUND: Median arcuate ligament syndrome (MALS) is a rare entity that occurs when the median arcuate ligament of the diaphragm is low-lying, causing a compression to the underlying celiac trunk. We reviewed the vascular changes associated with MALS in an effort to emphasize the seriousness of this disease and the complications that may result. METHODS: This is a retrospective descriptive analysis of 23 consecutive patients diagnosed with MALS between January 1, 2012 and December 31, 2015 at a tertiary medical center. Computed tomographic (CT) scans, medical records, and patient follow-up were reviewed. RESULTS: The number of patients included herein was 23. The median age was 56 years (17-83). Sixteen patients (69.6%) had a significant arterial collateral circulation. Eleven patients (47.8%) were found to have visceral artery aneurysms; 4 patients (36.4%) bled secondary to aneurysm rupture. All ruptured aneurysms were treated with endovascular approach. The severity of the hemodynamic changes appears to be greater with complete occlusion, CONCLUSIONS: MALS causes pathological hemodynamic changes within the abdominal vasculature. Follow-up is advised for patients who develop a collateral circulation. Resulting aneurysms should preferably be treated when the size ratio approaches three. Treatment of these aneurysms can be done via an endovascular approach coupled with possible celiac artery decompression to restore physiologic blood flow.

Propafenone hepatotoxicity: report of a new case and review of the literature.

Propafenone is a class Ic antiarrhythmic drug. It is a beta-adrenergic blocker that causes bradycardia and bronchospasm. It is metabolized primarily in the liver. Its bioavailability and plasma concentration differ among patients under long-term therapy. They are genetically determined by the hepatic cytochrome P-450 2D6. Hepatic toxicity is highly uncommon. To date, only eight patients were reported in the reviewed world literature. In this article, one new case will be reported emphasizing the importance of medication history taking in patients presenting with new-onset liver enzymes abnormalities.

The outcome of cervical exploration for asymptomatic and symptomatic patients with primary hyperparathyroidism.

This study examined the success and safety of cervical exploration in patients with primary hyperparathyroidism (HPT). The presentation, pathologic findings, and outcome of patients with asymptomatic primary HPT were compared with those with symptomatic disease. Records of patients undergoing cervical exploration for primary HPT from January 1993 until December 31, 2003, were reviewed. Information collected consisted of preoperative symptoms, calcium and parathormone (PTH) levels, imaging studies, operative findings, pathology, and outcome of the patients. The groups with asymptomatic and symptomatic primary HPT were compared. In all, 139 patients were studied; 31 (22.3%) were asymptomatic (group I), and 108 (77.7%) had symptoms (group II). The two groups were also comparable regarding mean age, sex, and the yield of the imaging studies. The mean preoperative serum calcium level was comparable in the two groups (11.1 mg/dl versus 11.3 mg/dl). However, PTH levels were significantly lower in group I than in group II (142 pg/dl versus 283 pg/dl, P = 0.01). The weight of the adenoma was also significantly less in group I than in group II (1082 mg versus 1679 mg P = 0.079). The outcome of the surgical exploration was comparable in the two groups with an immediate success rate close to 98% and a long-term success rate of 95.4%. Cervical exploration and parathyroidectomy in patients with primary HPT is a safe procedure with a high success rate and favorable outcome.
