In this case report, we describe a Parkinson's disease (PD) patient with limb-kinetic apraxia (LKA) in whom degeneration of the corticofugal tract (CFT) from the supplementary motor area (SMA) was observed in diffusion tensor tractography (DTT). ⋯ These observations indicated degeneration of the CFTs from the SMAs in both hemispheres in the patient. This degeneration might have, at least in part, contributed to the patient's LKA. The results of this study suggest that CFT degeneration could be one of the pathological mechanisms underlying LKA in patients with PD.

Radiofrequency ablation (RFA) is a first-line option for the treatment of small liver cancers, but the recurrence remains a problem affecting long-term survival. Hepatitis B virus (HBV) activity is associated with the prognosis of hepatocellular carcinoma (HCC). We investigated the significance of hepatitis B surface antigen (HBsAg) in HCC recurrence after curative RFA treatment in HBV-related small HCC. ⋯ The level of HBsAg was an independent risk factor for recurrence in patients with lower HBV-DNA levels. In hepatitis Be antigen (HBeAg)-negative patients, the 1-, 2-, and 3-year RFS rates were 79%, 64%, and 44%, respectively, for that with low HBsAg levels, compared with 73%, 50%, and 37%, respectively, for that with high HBsAg levels (P = .039). HBsAg might serve as a valuable marker to evaluate the risk of HCC recurrence in HBeAg-negative patients with low HBV viral load.

Charcot-Marie-Tooth disease (CMT) is typically an autosomal dominant, inherited neuropathy, although there is a rare male X-linked CMT. Such patients show central nervous system (CNS) involvement in addition to peripheral neuropathy. Recently, we encountered a patient who presented with acute disseminated encephalomyelitis (ADEM)-like symptoms, but was later diagnosed as having X-linked CMT (CMTX) due to a mutation. ⋯ Differential diagnosis of recurrent ADEM-like lesions in the cerebral white matter and peripheral neuropathy should include the possibility of CMTX disease.

Pancreatic encephalopathy (PE) refers to the abnormalities in mental status that complicate acute pancreatitis (AP). We report the case of a patient who developed AP that was complicated by PE and followed by fatal cerebral hemorrhage. ⋯ Although uncommon, PE should be properly monitored. Once the neurological symptoms of a patient dramatically worsen within a short time, the possibility of fatal cerebral hemorrhage should be considered.

Lung cancer is one of the most common cancers and is associated with a poor survival rate in the Chinese Han population. Analysis of genetic variants could lead to improvements in prognosis following lung cancer treatment. Resistin (RETN) is an important mediator of metabolic diseases and tumor progression. ⋯ Moreover, the RETN SNP rs3219175 with AG or AG + AA alleles was associated with a higher risk of distant metastasis than that in patients carrying GG alleles. We also used genotype-tissue expression datasets to compare the correlation of the RETN SNP rs3219175 in lung tissue and whole blood. In conclusion, our study demonstrated, for the first time, that RETN polymorphisms were correlated with lung cancer progression in the Chinese Han population.
