Radiation exposure and safety in low-dose CT-guided glycerol rhizotomy for trigeminal Neuralgia outside the operating room.

Background: Percutaneous rhizotomy of the Gasserian ganglion is a well-established intervention for patients suffering from refractory trigeminal pain, not amenable to pharmacological management or microvascular decompression. Traditionally conducted under fluoroscopic guidance using Hartel's technique, this study investigates a modified approach employing low-dose CT guidance to achieve maximal procedural precision and safety with the emphasis on minimizing radiation exposure.

Methods: A retrospective analysis of patients undergoing percutaneous rhizotomy of the Gasserian ganglion at our institution was undertaken.

Bevacizumab Does Not Inhibit the Formation of Liver Vessels and Liver Regeneration Following Major Hepatectomy: A Large Animal Model Study.

Background/aim: Patients with unresectable liver colorectal cancer metastases are treated with neoadjuvant chemotherapy often accompanied by biological therapy aimed at reducing the mass of metastases and thus increasing the chances of resectability. Bevacizumab comprises an anti-VEGF (vascular endothelial growth factor) humanized IgG monoclonal antibody that is used for biological therapy purposes. It acts to inhibit angiogenesis, thereby slowing down the growth of metastases.

Mixed neuroendocrine-non-neuroendocrine carcinoma of gallbladder: case report.

Background: Mixed neuroendocrine-non-neuroendocrine tumors (MINEN) of the gallbladder are extremely rare; indeed, the English expert literature reports a mere handful of case reports and case series on this topic. According to the WHO classification of 2010, MINEN are considered to be tumors consisting of two major components, neuroendocrine and non-neuroendocrine, each of which hosts at least 30% of the total cellular population. To date, the etiology and pathogenesis of MINEN have not been precisely determined and the non-specific symptoms generally result in late diagnosis (mainly in the terminal stages of the condition) and contribute to the generally poor prognosis.

[Ipsilateral traumatic dislocation of hip and knee joints. Case report].

Traumatic obturator dislocation of the hip without fracture associated with antero-lateral knee dislocation is considered to be an extreme injury. Such a case, which has never been treated in our department, is reported here. The patient was a 40-year-old man who suffered his injury in a motorcycle accident.

[Osteosynthesis of intracapsular femoral neck fractures by dynamic hip screw (DHS) fixation].

Purpose Of The Study: The treatment of femoral neck fractures shows a relatively high number of poor outcomes, usually due to late complications, such as avascular necrosis of the femoral head or pseudoarthrosis. The latter may develop when the osteosynthesis of osteoporotic bone fails. The aim of this retrospective study was to evaluate a group of patients treated by osteo- synthesis for intra-capsular femoral neck fractures at our department, and to verify indication criteria and identify the therapeutic procedures that are best suited to our conditions.
