A specificity of the vertebrobasilar system (VBS) is a convergent junction of paired vertebral arteries (VAs) in the basilar artery (BA) usually at the level of bulbopontine sulcus on the ventral side of the rhombencephalon. We revealed multiple VBS variations (a high junction of both VAs, absence of posterior inferior cerebellar arteries, short and ectatic BA, hypoplasia and initial duplication of the left anterior inferior cerebellar artery, and bilateral common trunks of the posterior cerebral and superior cerebellar arteries) in a 52-year-old male that routinely autopsied at the Institute of Forensic Medicine...

Surgery of the posterior fossa represents a technical challenge because of the proximity of the vessels of the cerebellum. If the arterial vascularization of the cerebellum is well known, the main arterial variations and the whole venous vascularization are probably under recognized. We describe the vascular organization and the main variations through photographs of colored latex perfused brains, obtained with a surgical microscope. The arterial vascularization of the cerebellum is based on three arteries which all originate from the vertebrobasilar system: the superior cerebellar artery (SCA), the anterior and inferior cerebellar artery (AICA), and the posterior and inferior cerebellar artery (PICA)...

BACKGROUND: Extreme conditioning programs (ECPs) are fitness training regimens relying on aerobic, plyometric, and resistance training exercises, often with high levels of intensity for a short duration of time. These programs have grown rapidly in popularity in recent years, but science describing the safety profile of these programs is lacking. HYPOTHESIS: The rate of injury in the extreme conditioning program is greater than the injury rate of weightlifting and the majority of injuries occur to the shoulder and back...

BACKGROUND: The solitary form of Spitz nevus is a common clinical entity in children, typically occurring on the face and extremities. However, less frequent variants of Spitz nevi, such as agminated forms and eruptive disseminated Spitz nevi (EDSN), have been described. The agminated form is characterised by localised clusters or segmental distribution of Spitz nevi on the face, back, or extremities. First described as "eruptive juvenile melanomata", EDSN is the rarest clinical variant, consisting of a widespread eruption of Spitz nevi, most frequently involving the trunk, buttocks, and proximal limbs, and usually occurs in the second to third decade of life...

BACKGROUND: The portal vascularization of segment IV (S4) of the liver has not been well described. Knowledge of the portal supply to S4 is of great interest for liver surgery and for interventional radiological procedures. This study aimed to analyse the distribution of portal vein branches supplying S4. METHODS: We retrospectively analysed data from patients operated on for liver tumours between 2007 and 2016. Patients with involvement of S4 branches or the left portal vein, previous liver surgery or poor quality imaging were excluded...

BACKGROUND: Rhabdomyosarcoma (RMS) is a malignant tumor of mesenchymal origin and comprises the largest category of soft-tissue sarcomas both in children and adolescents. From a pediatric oncology point of view, RMS has traditionally been classified into alveolar (ARMS) and embryonal (ERMS) subtypes. The anatomical localization of the tumor may vary, but commonly involve the head/neck regions, male and female urogenital tract or the trunk and extremities. CASE PRESENTATION: Here, we report two challenging cases involving 17- and 9-years-olds males where diffuse and multiplex bone lesions suggested either a hematological disease or a primary bone tumor (mesenchymal chondrosarcoma)...

The melanocortin 1 receptor is a Gs protein-coupled receptor implicated in melanogenesis regulation. The receptor gene is highly polymorphic, which accounts for the association of several of its single-nucleotide polymorphisms (SNPs) with an increased risk of melanoma. The present study aimed to evaluate the distribution of melanocortin 1 receptor gene variants R151C, R160W, and D294H within the Russian population of Eastern Siberia and its association with melanoma development. Melanoma patients (n=95) admitted to Krasnoyarsk Territorial Oncological Center and healthy controls (n=334) were enrolled in the study...

Dog bites are a major cause of injury, especially in the pediatric population. Common anatomic sites of dog bites on children are the peripheries and the head and neck. The torso is reportedly injured less frequently, and only 2 cases of intra-abdominal injury secondary to dog bites have been reported. We recently encountered a 3-year-old boy presenting with peritonitis who had sustained multiple dog bites to his trunk and upper limbs. Emergency laparotomy was performed. Surgical findings revealed penetration of the peritoneum and single perforation of the anterior gastric wall with multiple tooth marks; thus, the gastric perforation was debrided and repaired...

The musculoskeletal system is mainly composed of the bones, muscles, tendons, and ligaments, in addition to nerves and blood vessels. The greatest difficulty in an ultrasonographic freeze-frame created by the examiner is recognition of the targeted structures without indicators, since an elephant's trunk may not be easily distinguished from its leg. It is not difficult to find descriptive ultrasonographic terms used for educational purposes, which help in distinguishing features of these structures either in a normal or abnormal anatomic condition...

Schwannomas are mesenchymal tumors originating from Schwann cells in peripheral nerve sheaths. Although the tumor can be located in any part of the human body, the most common locations are the head, neck, trunk and extremities. Pancreatic schwannomas are rare. To our knowledge, only 64 cases of pancreatic schwannoma have been reported in the English literature over the past 40 years. In this paper, we present a pancreatic schwannoma in a 59-year-old female. Ultrasound, computed tomography and magnetic resonance imaging revealed the tumor located in the pancreatic body; however, accurate diagnosis was hard to obtain preoperatively and a pancreatic cystadenoma was preliminarily considered...

PURPOSE: Positional plagiocephaly (PP) is the most common subtype of asymmetric deformity in the infant skull. Cumulative evidence has demonstrated that PP is associated with abnormal neuromotor development; however, neurological assessment scores of infants with PP have not been well established, and PP has not attracted sufficient attention in China. This study used a Chinese version of the Infant Neurological International Battery (INFANIB) to identify neurological abnormalities among infants with PP and to determine the differences between infants with different (mild, moderate, and severe) degrees of PP...

Tracheostomy is a common procedure in head and neck surgery and emergency medicine to secure a patent airway. Surgeons should always be aware of anatomical variants of the branches of the aortic arch, which could lead to life-threatening complications. Open tracheostomy is the safest emergency procedure.

Anatomic variations of axillary artery branches are commonly encountered during radiological investigation and surgical operations. Their existence can confuse interpretation of radiological results and lead to undesired complications during surgery. In this report authors describe a rare case of a subscapular arterial trunk that gave origin to thoracodorsal, circumflex scapular, posterior humeral circumflex, and lateral thoracic artery. Such a variation might cause undesired sequelae during trauma management and a variety of common flap harvesting operations including latissimus dorsi, scapular and parascapular flaps...

Epilepsia partialis continua (EPC) is a particular type of epilepsy which is distinguished from "common epilepsy" by its characteristic semiological features. However, unusual manifestations should be described in order to give awareness at clinical diagnosis. In this case report we describe a rare EPC case not previously reported, in which left shoulder joint-trunk-hip joint jerk was present for 1 week. Abnormal electroencephalogram and cerebrospinal fluid results supported a diagnosis of viral encephalitis...
