Prognostic factors for postoperative survival in melanoma patients with bone metastasis.
Melanoma can spread to the bone by metastasis and is relevant to a poor outcome. However, because of the rarity of melanoma patients with bone metastasis, the prognostic postoperative survival factors of them have not been elucidated. The aim of this special population-based cohort was to elucidate the prognostic factors associated with postoperative survival. ⋯ Regarding overall survival, the 1-, 3-, and 5-year overall survival rates for the entire cohort were 36.2%, 15.4%, and 9.5%, respectively. Regarding cancer-specific survival, the 1-, 3-, and 5-year cancer-specific survival rates were 42.0%, 23.2%, and 16.6%, respectively. Within a cohort of melanoma patients with bone metastasis after surgery, our analysis showed that a smaller tumor size and the lack of metastases at other sites were predictors of survival.

Cortical anatomy plasticity in cases of cervical spondylotic myelopathy associated with decompression surgery: A strobe-compliant study of structural magnetic resonance imaging.
Using voxel-based morphometry (VBM), we studied cortical gray matter volume changes in patients with cervical spondylotic myelopathy (CSM) before and after cervical cord surgical decompression. We then discussed the structural damage mechanisms and the neural plasticity mechanisms involved in postsurgical CSM. Forty-five presurgical CSM patients, 41 of the same group followed-up 6 months after decompression surgery and 45 normal controls (NC) matched for age, sex and level of education underwent high-resolution 3-dimensional T1-weighted scans by 3.0 T MR. ⋯ Postsurgical CSM patients had significantly lower gray matter volume in the left caudate nucleus but greater regional gray matter volume in the right inferior temporal gyrus, the right middle orbitofrontal cortex (OFC) and the bilateral lingual gyrus / precuneus /posterior cingulate cortex than did NC. Abnormal areas gray volume in presurgical CSM and postsurgical CSM patients showed no significant correlation with clinical data (P > .05). Myelopathy in the cervical cord may cause chronic cerebral structural damage before and after the decompression stage, markedly in outlier brain regions involving motor execution/control, vision processing and the default mode network and in areas associated with brain compensatory plasticity to reverse downstream spinal cord compression and respond to spinal cord surgical decompression.

An esophago-bronchial fistula is one of the rare postoperative complications of esophageal cancer. There are various medical treatments, including suturing, endoscopic clip, and fibrin glue. However, these treatments often lead to unsatisfactory results, causing physicians to opt for surgical alternatives. The Over-The-Scope-Clipping (OTSC) system offers an alternative method for fistula closure. It can capture a large amount of tissue and is able to compress the lesion until it has fully healed. However, data indicating the efficacy of OTSC for esophago-bronchial fistula are limited. ⋯ We demonstrate that OTSC is useful in the management of esophago-bronchial fistulas, and may become a standard procedure for the endoscopic treatment of esophago-bronchial fistulas, replacing the use of stents, clips, or glue.

Risk factors for positive brain CT scan in children with traumatic brain injury and GCS = 15: A retrospective study.
It is controversial whether it is necessary to carry out head computed tomography (CT) examination for children who had a traumatic brain injury (TBI) but are conscious (Glasgow Coma Scale (GCS) = 15). The present study explored the risk/predictive factors of positive CT results in children with mild closed head injury and GCS = 15. This was a retrospective study of children (0-18 years of age) with TBI and GCS = 15 and treated at the First People's Hospital of Wenling between 06/2013 and 06/2018. ⋯ The top three clinical symptoms were headache (201/279, 72.0%), scalp hematoma (133/279, 47.7%), and nausea with or without vomiting (105/279, 37.6%). The multivariable analysis showed that scalp hematoma (OR = 3.040, 95%CI: 1.791-5.159, P < .0001), ear and nostril bleeding or periorbital soft tissue contusion (OR = 2.234, 95%CI: 1.087-4.590, P = .029), and nausea with or without vomiting (OR = 2.186, 95%CI: 1.255-3.810, P = .006) were independently associated with positive results of head CT. For children with TBI and GCS = 15, the factors independently associated with positive CT results are scalp hematoma, ear and nostril bleeding or periorbital soft tissue contusion, and nausea with or without vomiting.

Evaluation of the diagnostic utility of carbohydrate-deficient transferrin in chronic alcoholism: Results from Southwest China.
Although recent gathered evidence indicates that obtaining the diagnostic value of serum carbohydrate-deficient transferrin might be more useful for identifying alcohol abuse than other widely available biochemical tests; however, its precise value as an indicator of chronic alcoholism is unclear. The main objective is to investigate the diagnostic significance of carbohydrate-deficient transferrin in chronic alcoholism in the Chinese population. In this study, we enrolled (1) 52 physically healthy subjects, (2) 20 patients with nonalcoholic liver disease, and (3) 70 alcoholics. ⋯ Compared with the other parameters evaluated, CDT was a better indicator of alcoholism. It should, therefore, be actively promoted in clinical practice. However, the correlation between CDT and daily alcohol consumption needs further evaluation.
