A hemangioma doesn't often involve the scapula and concurrent high scapular deformity is also too. We present a case of capillary left scapula hemangioma at its superior angle with Cavendish grade 2 high scapular deformity treated by surgical intervention. Excision of the hemangioma and resection of the fibrous band attached to the superior angle of the scapula resulted in symptomatic and cosmetic improvement. Even though the causality between the two lesions is not clear, we cannot exclude the possibility that the hemangioma contributed to the development of high scapular deformity.

BACKGROUND: Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. METHODS: Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. RESULTS: Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderateintensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisuretime physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. CONCLUSION: Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

This review focuses on our effort in addressing the development and lesion-induced plasticity of the gravity sensing system. After severance of sensory input from one inner ear, there is a bilateral imbalance in response dynamics and spatial coding behavior between neuronal subpopulations on the two sides. These data provide the basis for deranged spatial coding and motor deficits accompanying unilateral labyrinthectomy. Recent studies have also confirmed that both glutamate receptors and neurotrophin receptors within the bilateral vestibular nuclei are implicated in the plasticity during vestibular compensation and development. Changes in plasticity not only provide insight into the formation of a spatial map and recovery of vestibular function but also on the design of drugs for therapeutic strategies applicable to infants or vestibular disorders such as vertigo and dizziness.

4.Romance of the three domains: how cladistics transformed the classification of cellular organisms.

Cladistics is a biological philosophy that uses genealogical relationship among species and an inferred sequence of divergence as the basis of classification. This review critically surveys the chronological development of biological classification from Aristotle through our postgenomic era with a central focus on cladistics. In 1957, Julian Huxley coined cladogenesis to denote splitting from subspeciation. In 1960, the English translation of Willi Hennig's 1950 work, Systematic Phylogenetics, was published, which received strong opposition from pheneticists, such as numerical taxonomists Peter Sneath and Robert Sokal, and evolutionary taxonomist, Ernst Mayr, and sparked acrimonious debates in 1960-1980. In 1977-1990, Carl Woese pioneered in using small subunit rRNA gene sequences to delimitate the three domains of cellular life and established major prokaryotic phyla. Cladistics has since dominated taxonomy. Despite being compatible with modern microbiological observations, i.e. organisms with unusual phenotypes, restricted expression of characteristics and occasionally being uncultivable, increasing recognition of pervasiveness and abundance of horizontal gene transfer has challenged relevance and validity of cladistics. The mosaic nature of eukaryotic and prokaryotic genomes was also gradually discovered. In the mid-2000s, high-throughput and whole-genome sequencing became routine and complex geneologies of organisms have led to the proposal of a reticulated web of life. While genomics only indirectly leads to understanding of functional adaptations to ecological niches, computational modeling of entire organisms is underway and the gap between genomics and phenetics may soon be bridged. Controversies are not expected to settle as taxonomic classifications shall remain subjective to serve the human scientist, not the classified.

Background/Aims:
Data on treatment efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) for chronic hepatitis C virus (HCV) infection in Asian patients with severe renal impairment are limited. This study aimed to study the treatment and side effects of GLE/PIB in these patients infected with non-1 genotype (GT) HCV.
Methods:
We prospectively recruited patients with Child’s A cirrhosis and eGFR <30 mL/min/1.73 m2 in Hong Kong and Taiwan during 2017–2018 to receive GLE/PIB treatment.
Results:
Twenty-one patients (GT2, n=7; GT3, n=6; and GT6, n=8) received GLE/PIB for 11.2±1.8 weeks. All except one were treatment-naïve. GLE/PIB was initiated in 16 patients while on dialysis (seven on peritoneal dialysis [PD] and nine on hemodialysis) and in five patients before dialysis. One patient died of PD-related peritonitis during treatment and two were lost to follow up. The SVR12 rate in the remaining 18 patients was 100%. All patients achieved undetectable levels at 4-, 12-, 24- and 48-week after treatment. Patients with deranged alanine aminotransferase showed normalization after 4 weeks and the response was sustained for 48 weeks. No significant adverse event was observed.
Conclusions
GLE/PIB treatment was associated with high efficacy and tolerability in HCV-infected patients with severe renal impairment.
