Acute portal vein thrombosis secondary to hyperhomocysteinemia with folic acid deficiency and methyl tetrahydrofolate reductase mutation: a case report and literature review

Portal vein thrombosis secondary to postoperative gastric cancer: Report of two cases

Few cases of portal vein thrombosis secondary to gastric cancer surgery have been reported. Here we report the diagnosis and management of two such cases. Case 1: Gastric carcinoma with acute hematemesis was detected by endoscopy in the gastric body of a 48-year-old woman. Histologic examination revealed signet-ring cell carcinoma with marked invasion of the vessels and nerves. Laparoscopic partial gastrectomy and Roux-en-Y gastrogastrostomy were performed. One month after surgery, imaging examination showed the formation of thrombi in the main portal vein and the right hepatic vein. Case 2: Gastric carcinoma with pyloric obstruction was clinically diagnosed in a 66-year-old woman. Laparoscopic partial gastrectomy and Billroth Roux-en-Y gastrogastrostomy were again performed. Two months after surgery, an abdominal imaging examination detected a thrombus in the right hepatic vein. Clinicians should consider portal vein thrombosis in patients with hyperthermia combined with an abnormal increase in procalcitonin.

Androgen status in non-diabetic elderly men with heart failure

PURPOSE

We aimed at evaluating androgen status (serum testosterone [TT] and estimated free testosterone [eFT]) and its determinants in non-diabetic elderly men with heart failure (HF). Additionally, we investigated its associations with body composition and long-term survival.

METHODS

Seventy three non-diabetic men with HF and 20 healthy men aged over 55 years were studied. Echocardiography, 6-min walk test, grip strength, body composition measurement by DEXA method were performed. TT, sex hormone binding globulin, NT-proBNP, and adipokines (adiponectin and leptin) were measured. All-cause mortality was evaluated at six years of follow-up.

RESULTS

Androgen status (TT, eFT) was similar in elderly men with HF compared to healthy controls (4.79 ± 1.65 vs. 4.45 ± 1.68 ng/ml and 0.409 ± 0.277 vs. 0.350 ± 0.204 nmol/l, respectively). In HF patients, TT was positively associated with NT-proBNP (r= 0.371, p = 0.001) and adiponectin levels (r = 0.349, p = 0.002), while inverse association was noted with fat mass (r = -0.413, p < 0.001). TT and eFT were independently determined by age, total fat mass and adiponectin levels in elderly men with HF (p < 0.05 for all). Androgen status was not predictor for all-cause mortality at six years of follow-up.

CONCLUSIONS

In non-diabetic men with HF, androgen status is not altered and is not predictive of long-term outcome.
