Both NCPB and VSPL provide significant reduction of pain and improvement of quality of life in inoperable pancreatic cancer patients. They present rather similar efficacy, but lower invasiveness of NCPB, in combination with its more positive effect on quality of life, pre-disposes it as being the preferred method.

We report a case of Wernicke's encephalopathy after sleeve gastrectomy, which had been complicated by stomach wall edema and aggravated by dietary non-compliance. Despite intense parenteral nutrition, thiamine deficiency became clinically evident. It suggests that nutritional preparations used were unable to cover the increased thiamine requirement. After intense thiamine supplementation, gradual improvement occurred during the 6 months after the diagnosis, without permanent cognitive impairment. Clinicians involved in postoperative management of bariatric surgery patients must consider Wernicke's syndrome in hyper-emetic patients, who show unclear neurological deterioration. Early diagnosis and treatment can instantly improve the patient's condition without permanent sequelae.

Human HtrA proteins are serine proteases involved in essential physiological processes. HtrA1 and HtrA3 function as tumor suppressors and inhibitors of the TGF-β signaling pathway. HtrA2 regulates mitochondrial homeostasis and plays a pivotal role in the induction of apoptosis. The aim of the study was to determine whether the HtrA proteins are involved in thyroid carcinogenesis. We used the immunoblotting technique to estimate protein levels of HtrA1, HtrA2, long and short variants of HtrA3 (HtrA3-L and HtrA3-S) and TGF-β1 in tissues of benign and malignant thyroid lesions, and control groups. We found that the levels of HtrA2 and HtrA3-S were higher in thyroid malignant tumors compared to normal tissues and benign tumors. The HtrA3-L level was increased in malignant tumor tissues compared to benign tumor tissues and control tissues from patients with benign lesions, and elevated in normal tissues from patients with thyroid carcinoma compared to normal tissues from patients with benign lesions. We also compared levels of HtrA proteins in follicular thyroid carcinoma (FTC) and papillary thyroid carcinoma (PTC) and found that these types of carcinoma differed in the expression of HtrA3-S and HtrA1. These results indicate the implication of HtrA proteins in thyroid carcinogenesis suggest that HtrA3 variants may play different roles in cancer development, and that the increased HtrA3-L levels in thyroid tissue could be correlated with the development of malignant lesions. The TGF-β1 levels in tumor tissues were not significantly altered compared to control tissues.

pHPT patients have significantly decreased concentration level, nonverbal learning process, access to verbal resources and constructional and visual memory ability. Thus, neuropsychological testing may be useful in the decision making for early surgery in patients with mild asymptomatic disease in order to avoid further deterioration of cognitive functions.
