REVIEW
Sang Myung Woo
The term of biliary tract cancer (BTC) refers to all tumors that arise from the biliary tract or the biliary drainage system, including the intra- and extra-hepatic bile ducts as well as the gallbladder. BTCs are aggressive tumors with limited treatment options and poor overall survival. Currently, surgery remains to be the only potentially curative treatment, and most patients develop recurrence. For advanced tumors, only limited effective treatment modalities exist today. Gemcitabine plus cisplatin is considered as a standard option for advanced biliary cancer...

Ivermectin (IVM) is a broad-spectrum anti-parasitic drug with significant anti-inflammatory properties. The emergence of treatment resistance to lindane, permethrin, and possibly malathion complicates the global strategy for management of common parasitic skin diseases such as scabies and head lice. In this regard. IVM has been safely and effectively used in the treatment of these common human infestations. In addition, IVM may be useful in inflammatory cutaneous disorders such as papulopustular rosacea where demodex may play a role in pathogenesis...

Superficial angiomyxoma is a distinctive cutaneous soft tissue neoplasm that is clinically variable, infrequent, and benign. However, this tumor has a high propensity for local recurrence. There is a known association of angiomyxomas with Carney complex. We report a case of superficial angiomyxoma in a 28-year-old woman who presented with an erythematous, mul-tilobulated nodule on the nipple. This tumor has a predilection for the trunk, head and neck, extremities, and genitalia. The present case, hence, is unusual, because the lesion developed on the nipple...

Dermatofibrosarcoma protuberans (DFSP) is an uncommon intermediate-grade soft tissue sarcoma. The tumor is found preferentially on the trunk, whereas the head and neck region are affected in only 10% to 15% of cases. We report the case of a 44-year-old woman with a 5-month history of an asymptomatic, firm, yellow nodule in the mucosa of the right cheek measuring 2.5 cm. The clinical diagnosis was lipoma and an excisional biopsy was obtained. Histopathological analysis revealed a proliferation of spindle-shaped mesenchymal cells arranged in interlacing fascicles amidst fibrous stroma...

Syringocystadenoma papilliferum is a rare cutaneous adnexal tumor that usually arises in the head and neck region. It may develop de novo or within a nevus sebaceus. Linear syringocystadenoma papilliferum is an uncommon variant of this benign tumor. We report a child with linear retroauricular distribution of syringocystadenoma papilliferum. A background nevus sebaceus was shown histologically. Total excision was curative with no recurrence. An association between the linear variant of syringocystadenoma papilliferum and nevus sebaceus has not been reported previously...

Blue nevi are benign proliferations of melaninproducingdendritic melanocytes located in thedermis. These nevi tend to occur mostly on the skin,predominantly on the head and neck, dorsal aspectsof the distal extremities, and the sacral area, butcan also occasionally appear on mucosal surfaces.Blue nevi of the nail apparatus are uncommon. Themajority originate in the nail matrix where there is ahigher density of melanocytes. Herein we report ona 47-year-old man with a rare common blue nevus ofthe nail bed, an area with low melanocyte density...

Blast-induced traumatic brain injury (TBI) has been on the rise in recent years due to the increasing use of improvised explosive devices (IEDs) in conflict zones. Our study investigates the response of a helmeted human head subjected to a blast of 1 atm peak overpressure, for cases with and without a standard polycarbonate (PC) face shield and for face shields comprising of composite PC and aerogel materials and with lateral edge extension. The novel introduction of aerogel into the laminate face shield is explored and its wave-structure interaction mechanics and performance in blast mitigation is analysed...

An 83-year-old man with arch aneurysm underwent total arch replacement with frozen elephant trunk and extra-anatomical left subclavian artery bypass. One year later, he felt dizziness associated with head rotation. The hypoplastic left vertebral artery was occluded by a thrombus extending from the left subclavian artery ligation site, and the dynamic stenosis of right vertebral artery by head rotation induced dizziness. He was diagnosed with Bow Hunter syndrome. Vertebral artery hypoplasia represents a possible cause of this rare complication...

Background.: Little is known regarding the optimal treatment of ventriculoperitoneal (VP) shunt infections in adults. Our aim was to assess the efficacy of treatment strategies and to identify factors that predict failure. Methods.: Retrospective, observational study of patients aged ≥12 years with VP shunt infections (1980 -2014). Therapeutic approaches were classified under 4 headings: only antibiotics (OA), one-stage shunt replacement (OSSR), two-stage shunt replacement (TSSR), and shunt removal without replacement (SR)...

Background: Antiretrovirals (ARVs) affect bone density and turnover, but their effect on risk of fractures and osteonecrosis of the femoral head is less understood. We investigated if exposure to ARVs increases the risk of both bone outcomes. Methods: EuroSIDA participants were followed to assess fractures and osteonecrosis. Poisson regression identified clinical, laboratory and demographic predictors of either bone outcome. Ever, current and cumulative exposures to ARVs were assessed...

Bernd Lütkenhöner
Small electrodynamic shakers are becoming increasingly popular for diagnostic investigations of the human vestibular system. More specifically, they are used as mechanical stimulators for eliciting a vestibular evoked myogenic potential (VEMP). However, it is largely unknown how shakers perform under typical measurement conditions, which considerably differ from the normal use of a shaker. Here, it is shown how the basic properties of a shaker can be determined without requiring special sensors such as accelerometers or force gauges...

The genus Dipsacus is characterized by a remarkable bidirectional flowering sequence and a rare phyllotactic pattern. Considering that flower initiation and flowering sequence may be interconnected, we document the development of the head meristem in Dipsacus fullonum. Our results indicate a gradual change in the geometry of the head meristem beginning with a dome shaped stage, continuing with a remarkable widening in the middle part of the head meristem and ending in a spindle-like form. Quantitative data confirm that meristem expansion is higher in the middle part than at the base of the meristem...

Although most pediatric proximal humeral fractures can be successfully treated conservatively with satisfactory results, many operative techniques have been described for the treatment of displaced proximal humeral fractures. The aim of this study is to evaluate the efficacy of percutaneous fixation using a modified palm tree technique for proximal humerus fractures in children. Between March 2011 and May 2013, the modified palm tree technique was used for the management of 30 children (20 boys and 10 girls) with displaced proximal humeral fractures...

BACKGROUND: The Injury Severity Score (ISS) is the most commonly used injury scoring system in trauma research and benchmarking. An ISS>15 conventionally defines severe injury; however, no studies evaluate whether ISS performs similarly between adults and children. Our objective was to evaluate ISS and AIS to predict mortality and define optimal thresholds of severe injury in pediatric trauma. METHODS: Patients from the Pennsylvania trauma registry 2000-2013 were included...

Non-Hodgkin lymphoma is the second most common neoplasm of the head and neck after squamous cell carcinoma. However, it accounts for only 3.5% of all malignancies of the oral cavity. Oral lesions are often a component of disseminated disease process that may involve regional lymph nodes or may at times represent the primary extra nodal form of the disease. Although, isolated oral lymphoma in adults is extremely rare, this paper presents a patient with Burkitt lymphoma in an adult male with atypical clinical presentation primarily involving the oral soft tissue...
