This study demonstrates that in intertrochanteric 31-A1 and 31-A2 stable fractures, the absence of distal locking screw does not compromise bone healing and prevents several clinical complications.

Minimally invasive image-guided thermal ablation is becoming increasingly common as an alternative to surgery for the treatment of benign thyroid nodules. Among the various techniques for thermal ablation, laser ablation (LA) is the least invasive, using the smallest applicators available on the market and enabling extremely precise energy deposition. However, in some cases, multiple laser fibers must be used simultaneously for the treatment of large nodules. In this review, the LA technique is described, and its main clinical applications and results are discussed and illustrated.

Breast cancer metastases to the gastrointestinal tract are very rare occurrences. Among the histological subtypes of breast cancer, invasive lobular carcinomas have a high capacity of metastasis to uncommon sites including the stomach. Conversely, there has not been sufficient evidence supporting the gastric metastasis of invasive ductal carcinoma. Herein, we report a unique case of metastatic ductal breast carcinoma mimicking primary linitis plastica in a male patient, particularly focusing on the clinical and pathological features of presentation. Moreover, we propose a immunohistochemical panel of selected antibodies including those for cytokeratin 20, cytokeratin 7, estrogen receptor, progesterone receptor, E-cadherin, gross cystic disease fluid protein 15, and GATA binding protein 3 for an accurate differential diagnosis.

tPLB seems to be an effective and feasible procedure, accompanied by a low risk of pneumothorax in UPLN cases.

The discovery of sensitizing epidermal growth factor receptor (EGFR) mutations as a predictive marker of sensitivity to first-generation EGFR tyrosine kinase inhibitors (TKIs) has dramatically changed the paradigm of care for advanced non-small cell lung cancer (NSCLC) patients. Unfortunately, the majority of patients with EGFR-mutant NSCLC treated with EGFR-TKIs develop acquired resistance within 14-16 months. T790M mutation recently emerged as a major determinant of acquired resistance to gefitinib and erlotinib. Osimertinib (AZD9291) is a novel mono-anilino-pyrimidine third-generation EGFR TKI targeting both sensitizing and T790M EGFR-mutation which showed promising results in T790M-positive NSCLC. Here we report two cases of gefitinib- or erlotinib-pretreated NSCLCs with a T790M mutation-positive (as assessed on plasma through the therascreen EGFR test) disease and untreated, asymptomatic central nervous system metastases that responded to treatment with osimertinib.

Image-guided thermal ablations are increasingly applied in the treatment of renal cancers, under the guidance of ultrasound (US) or computed tomography (CT). Sometimes, multiple ablations are needed. The aim of the present study was to evaluate the long-term results in patients with renal mass treated with radiofrequency ablation (RFA) with both US and CT, with a focus on the multiple ablations rate. 149 patients (median age 67 years) underwent RFA from January 2008 to June 2015. Median tumor diameter was 25 mm (IQR 17–32 mm). Median follow-up was 54 months (IQR 44–68). 27 (18.1%) patients received multiple successful ablations, due to incomplete ablation (10 patients), local tumor progression (8 patients), distant tumor progression (4 patients) or multiple tumor foci (5 patients), with a primary and secondary technical efficacy of 100%. Complications occurred in 13 (8.7%) patients (6 grade A, 5 grade C, 2 grade D). 24 patients died during follow-up, all for causes unrelated to renal cancer. In conclusion, thermal ablations with the guidance of US and CT are safe and effective in the treatment of renal tumors in the long-term period, with a low rate of patients requiring multiple treatments over the course of their disease.

This study demonstrated EVOH 6% appears to be as safe and effective as coils in the treatment of non-variceal UGIB.
