Calciphylaxis, known as calcific uremic arteriolopathy, is a rare cause of dry gangrene. Despite an increase in the clinical recognition of demographic characteristics and risk factors associated with calciphylaxis, it remains a poorly understood disease with high mortality. ⋯ This case contributed to the current understanding of calciphylaxis. Since no standard treatment is available and the prognosis remained poor, early, and accurate diagnosis of calciphylaxis is important. We here report the current case and provide data for the diagnosis and treatment of this kind of disease.

Observational Study
Plethysmographic variability index and perfusion index in patients with axillary brachial plexus nerve catheters: An observational study.
Axillary nerve blocks are commonly using for forearm and hand surgery. Especially for finger replacement it has been shown continuous plexus blockade improves microcirculation. Addition to that benefit continuous blockade provides adequate analgesia. ⋯ The PI increases after peripheral plexus blockade and may be used as an indicator for successful block placement in awake patient. And also, it may be used as an indicator for catheter effectiveness after surgery. But PVI values cannot detect that kind of relation with nerve blockade.

There are few studies on the predictive factors of early recurrence (ER) and late recurrence (LR) of advanced gastric cancer (GC) after curative surgery. Our study aims to explore the independent predictors influencing the prognosis between ER and LR in patients with advanced GC after curative intent surgery respectively. And we will further develop nomograms for prediction of post recurrence survival (PRS). ⋯ The calibration curves for probability of 1-, 2-, and 3-year PRS showed excellent predictive effect. Internal validation concordance indexes of PRS were 0.722 and 0.671 for ER and LR respectively. In view of the different predictive factors of ER and LR of GC, the practical predictive model may help clinicians make reasonable decisions.

Respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) infections are common in children worldwide. However, the clinical factors related to extended hospitalization in Japanese patients aged ≥3 years remain elusive. We aimed to elucidate the clinical risk factors contributing to hospital stays ≥7 days in patients with RSV and hMPV infections. ⋯ The presence of prophylactic antibiotics usage, co-bacterial colonization, and underlying diseases were extracted by univariate analysis (P < .05). In multivariate analysis, underlying diseases were determined as an independent clinical risk factor (odds ratio 8.09, P = .005). Underlying diseases contributed to extended hospitalization in RSV- or hMPV-infected patients ≥3 years of age.

Osteosarcoma (OS) is one of the most prevalent malignant bone tumors. The proportion of patients with limb OS was relatively high. Lung metastasis (LM) and bone metastasis are the first and second most common metastatic types of OS, respectively. ⋯ In limb OS patients with LM and BM, the mean survival months in the no surgery group was lower than in the surgery group. T stage and radiotherapy significantly influence the occurrence of limb OS with lung and/or BM. Surgery at the primary site has been shown to be effective in improving the survival rate of patients with lung and/or BM.
