Abdominal and pelvic hernias may be indolent and detected incidentally, manifest acutely with pain and distress, or cause chronic discomfort. Physical examination findings are often ambiguous and insufficient for optimal triage. Therefore, accurate anatomic delineation and identification of complications are critical for effective treatment planning. Imaging, particularly computed tomography, provides a vital understanding of the hernia's location and size, involved viscera, and severity of associated complications...

Type IV paraesophageal hernia (PEH) is very rare and is characterized by the intrathoracic herniation of the abdominal viscera other than the stomach into the chest. We describe a case of a 90-year-old male patient who presented at our emergency department complaining of epigastric pain that he had experienced over the past few hours and getting progressively worse. On the day after admission, his pain became severe. Chest radiography revealed an intrathoracic intestinal gas bubble; emergency exploratory laparotomy identified a type IV PEH with herniation of only the jejunum with perforated diverticula on mesenteric side through a hiatal defect into mediastinum...

Angiosarcoma is a rare soft tissue sarcoma, and the data about its clinicopathological features and prognostic factors are limited. The purpose of the present study was to report a large series of angiosarcoma at a single institution. Clinical data from 200 cases of angiosarcoma from the Shanghai Cancer Center (Shanghai, China) between March 2006 and March 2014 were retrospectively analyzed. The study population included 97 males and 103 females with ages between 4 and 91 years (median, 53 years). According to the tumor location, 200 cases were divided into 4 groups: i) Tumors involving the head and neck; ii) breast; iii) viscera (including internal organs and bone); and iv) soft tissue (including trunk and extremities)...

Situs inversus totalis is the mirror image of situs solitus, the normal position of abdominal and thoracic viscera. Many associated intraabdominal anomalies have been described with this condition. However, association of choledochal cyst with situs inversus has never been reported. Diagnosis and surgical procedures for abdominal pathology in patients with situs inversus totalis are technically more complicated and pose unique challenges because of left-right transposition of the visceral organs. The choledochal cyst is usually diagnosed in the neonatal period or during childhood...

This study evaluates the feasibility of using simultaneous mass balances of different nutrients as a tool for optimizing feeding composition in anaerobic digestion. Different ratios, among them total chemical oxygen demand/total Kjeldahl nitrogen (TCOD/TKN) and soluble chemical oxygen demand/total chemical oxygen demand (SCOD/TCOD) were assessed. As an example, the TCOD/TVS ratio reached a value of 1.73 kg O2/kg TVS, while, with the exception of the sewage sludge, pig slurry and animal wastes, a linear relationship was established between phosphorus and nitrogen, whose slope was found to be 0...

The vagus nerve is responsible for the parasympathetic innervation of the major thoracic and abdominal organs. It also carries sensory afferent fibres from these viscera and reaches different brain structures. These connections have proven useful in the treatment of different diseases. Afferent stimulation of the left vagus nerve is used to treat epilepsy and major depression, and stimulation of the right vagus nerve is being tried for the treatment of heart failure. The device used for the therapy delivers intermittent stimuli...

Introduction: Heterotopic ossification involves the formation of trabecular bone outside of its usual anatomic location. While it is a well-known entity in orthopedic and spinal injury literature, it has also been observed after midline laparotomy and severe burns. Methods/Case Report: We present a case of a 69-year-old man who presented for ventral hernia repair after a prolonged postoperative course following colectomy involving an open abdomen with eventual closure with skin grafting. Results: Two large calcified objects were encountered during the excision of the skin graft from the small intestine and during the component separation...

Melanomas are aggressive cancers that present as cutaneous, mucosal and ocular lesions with the ability to metastasise widely. There are, however, occasions where lesions are found in distant sites such as lymph nodes, viscera and subcutaneous tissues without clinically apparent skin involvement. This is known as metastatic melanoma of unknown primary (MUP). Its presentation in skeletal muscle is rare, and the available literature is sparse. This article presents an 85-year-old woman with a MUP presenting in the right temporalis muscle, which was diagnosed with the aid of the ultrasound-guided core biopsy...

PURPOSE: Although recommended placement of IVC filters is with their tips positioned at the level of the renal vein inflow, in practice, adherence is limited due to clinical situation or IVC anatomy. We seek to evaluate the indwelling and retrieval complications of IVC filters based on their specific position within the infrarenal IVC. MATERIALS AND METHODS: Retrospective, single institution study of 333 consecutive infrarenal vena cava filters placed by interventional radiologists in patients with an average age of 62...

OBJECTIVE AND METHODS: Metabolic viscera and their vasculature are richly innervated by peripheral sensory neurons. Here, we examined the metabolic and inflammatory profiles of mice with selective ablation of all Nav1.8-expressing primary afferent neurons. RESULTS: While mice lacking sensory neurons displayed no differences in body weight, food intake, energy expenditure, or body composition compared to controls on chow diet, ablated mice developed an exaggerated inflammatory response to high-fat feeding characterized by bouts of weight loss, splenomegaly, elevated circulating interleukin-6 and hepatic serum amyloid A expression...

INTRODUCTION: Impalement injury is a rare type of mechanical injury following forceful insertion of projecting object into the body. Careful planning for removal of the impaling object is essential to decrease the blood loss and preserve the function of the injured organ. PRESENTATION OF CASE: A 27 year-old male fell from 4m height over a U shaped projecting up metallic bar. The bar penetrated the left side of the pelvis and traversed through the left iliac bone causing a comminuted fracture in the supra-acetabular region extending to the left psoas muscle, injuring the viscera and causing fracture of the right femur...

The Australian paralysis tick (Ixodes holocyclus) secretes neuropathic toxins into saliva that induce host paralysis. Salivary glands and viscera were dissected from fully engorged female I. holocyclus ticks collected from dogs and cats with paralysis symptoms. cDNA from both tissue samples were sequenced using Illumina HiSeq 100 bp pair end read technologies. Unique and non-redundant holocyclotoxin sequences were designated as HT2-HT19, as none were identical to the previously described HT1. Specific binding to rat synaptosomes was determined for synthetic HTs, and their neurotoxic capacity was determined by neonatal mouse assay...
