Extrahepatic cholangiocarcinoma requires invasive surgery and is associated with poor prognosis; thus, a prognostic biomarker is highly needed. Extrahepatic cholangiocarcinoma is sub-classified into two types based on their location, namely perihilar and distal. Perihilar cholangiocarcinoma requires lobectomy as curative surgical resection, whereas the distal requires pancreatoduodenectomy. HMGA2 overexpression is reported to correlate with progression, aggressiveness, dissemination and poor prognosis in several types of cancers. Although its association with extrahepatic cholangiocarcinoma has been reported, none of the previous studies assessed its significance in each subtype.

We assessed the expression of HMGA2 protein in surgical specimens after curative intent surgery in 80 patients including 41 with perihilar cholangiocarcinoma and 39 with distal cholangiocarcinoma by immunohistochemistry. We then examined its association with clinicopathological findings and patient survival outcomes.

We found that HMGA2 was expressed in 51% (21 of 41) of perihilar cholangiocarcinoma and 41% (16 of 39) of distal cholangiocarcinoma samples. In perihilar cholangiocarcinoma, we found significant correlations between expression and vascular invasion and perineural invasion. In distal cholangiocarcinoma, we found that protein levels correlated with tumor grade. #link# Univariate and multivariate analyses demonstrated that HMGA2 expression was an independent poor prognostic factor for patients with both subtypes of disease.

Our results revealed that HMGA2 expression as an independent prognostic marker for both perihilar and distal cholangiocarcinoma that were resected with curative intent.

There is a need to assess clinical practice in light of increasing literature recommending fixation of posterior malleolus (PM) fractures. This multicentre study examines treatment approaches, within both Major Trauma Centres and District General Hospitals and role of radiographs and CT scanning.

Trauma lists and databases were used to identify patients and data collected from electronic and paper medical records and imaging systems between August 2017-18. Analysis of treatment and outcomes was then conducted.

One-hundred-and-sixty ankle fractures were included in the study, only 68 ankle fractures underwent CT scanning following initial radiographs and of these, 65 were managed operatively, with 32 undergoing PM fixation. Syndesmotic stabilisation was performed in 9.6% where the PM was fixed.

CT is still under-utilised, PM fractures that appear to be anything other than small avulsion-type injuries should undergo CT scanning. Syndesmotic stabilisation is statistically less likely to be performed with fixation of the PM.

Spinal muscular atrophy (SMA) is caused by a defect in the survival motor neuron 1 (SMN1) gene. The Cooperative Study of the natural history of SMA Type I in Taiwan is a retrospective, longitudinal, observational study that helps in further understanding SMA disease progression in patients who have not received disease-modifying therapeutic interventions.

Case report forms were used to collect demographics; genetic confirmation; SMN2 copy number; treatment patterns; and clinical outcomes including ventilator use, endotracheal tube intubation, tracheostomy, gastrostomy, complications, and survival.

A total of 111 patients with SMA Type I were identified over the study period (1979-2015). Mean (median) age of onset and age at confirmed diagnosis were 1.3 (0.8) and 4.9 (4.4) months, respectively. SMN1 deletion/mutation was documented in 70 patients and SMN2 copy number in 32 (2 copies, n=20; 3 copies, n=12). At 240months, survival probability for patients born during 1995-2015 versus 1979-1994 was significantly longer (p=0.0057). Patients with 3 SMN2 copies showed substantially longer 240-month survival versus patients with 2 SMN2 copies. Over the 36-year period, mean (median) age at death was 31.9 (8.8) months. As of Tucatinib cost , 95 patients had died, 13 were alive, and 3 were lost to follow-up. The use of supportive measures (tracheostomy and gastrostomy) was associated with improved survival.

These data describe the short survival of patients with SMA Type I in Taiwan in the pretreatment era, emphasizing the positive impact of supportive measures on survival.

Bottom shuffling is a locomotion strategy that precedes independent walking in some infants. Shuffling babies are generally considered to have favorable outcomes. The aim of the present study was to reveal clinical features and neurodevelopmental outcomes of shuffling babies who visited a child developmental center.

We studied 48 shuffling babies who visited Toyota Municipal Child Development Center from April 2007 to March 2015. We excluded patients with cerebral palsy, Down syndrome, or congenital disorders. In 2018, we retrospectively reviewed the clinical charts of the enrolled children. We investigated family history, neurological findings, and the developmental outcome during the follow-up period.

During the follow-up period, 20 children (42%) were diagnosed with ASD. Gross motor development in infancy was not different between infants with and without ASD. The rate of poor eye contact at the first visit and a delay in the first word speech were significantly higher in infants with ASD than in infants without ASD.
