Hollow visceral

M R Aboobakar, J P Singh, K Maharaj, S Mewa Kinoo, B Singh
Gastric perforations following blunt abdominal trauma are rare, accounting for < 2% of all blunt abdominal injuries. Isolated blunt gastric ruptures are uncommon. They are usually associated with other solid visceral injuries. Injuries to the stomach are associated with the highest mortality of all hollow viscus injuries. Severity of the injury, timing of presentation and presentation following the last meal as well as concomitant injuries are important prognostic factors. Imaging modalities may be unreliable in making a diagnosis and thus clinical vigilance is mandatory...

Computed tomography (CT) is key to the assessment of hemodynamically stable patients with blunt or penetrating trauma to the abdomen and pelvis. Dual-energy (DE) CT is a technology that allows acquisition of data at both high and low kilovolt peaks, allowing materials that have different x-ray absorption behaviors as a function of kilovolt peak (such as iodine) to be differentiated and quantified. DE CT has a variety of postprocessing applications that may be helpful in abdominal and pelvic trauma, including iodine-selective imaging, virtual monenergetic imaging, and virtual noncalcium imaging...

Introduction: The vast majority of patients presenting with pneumoperitoneum have visceral organ perforation and require urgent diagnostic laparoscopy. Nonsurgical causes are relatively rare and may be attributed to multiple etiologies. Case Presentation: Here we describe the case of a 38-year-old Caucasian female who presented to the emergency department with three days of cramping, epigastric abdominal pain. Her physical exam was notable for tenderness to palpation in the epigastric area and abdominal and chest X-rays showed free air under the diaphragm...

Laparoscopic repair for ventral and incisional hernias was first reported in the early 1990s. It uses intraperitoneal only mesh placement to achieve a tension-free repair of the hernia. However, in recent years, there has been greater concern about long-term complication involving intraperitoneal mesh placement. Many case reports and case series have found evidence of mesh adhesion, mesh fistulation, and mesh migration into hollow organs including the esophagus, small bowel, and large bowel, resulting in various major acute abdominal events...

The variability of osteological characters has been investigated in cyprinid fish of the genus Oreoleuciscus (Potanin Altai osman) from the river Zavkhan; this fish species is endemic for water bodies of Central Asia. Multivariate analysis of 13 quantitative parameters of the size of the cerebral and visceral skull and the pectoral girdle and the construction of ontogenetic channels allowed the detection of morphologically distinct forms in the fluvial habitats. The result obtained provides additional proof of the possibility of sympatric diversification of fish in river ecosystems...

Blunt colorectal traumas are rare clinical entities with a challenging diagnostic and operative management. We describe the case of a 40-year-old man, victim of an accidental fall from a height of four meters who was subsequently diagnosed to have a blunt rectal trauma. A first CT scan showed fracture of the skull and an extensive subcutaneous haematoma of the lower back associated with a fracture of the left transverse processes of lumbar vertebrae. No other visceral abdominal lesions were recognized and patient was admitted to our department for observational studies...

Subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), and fat beneath the dermis layer were investigated using a ball lens top hollow optical fiber Raman probe (BHRP). Hamsters were fed with trilinolein (TL) and tricaprin (TC) for six weeks and measurements were carried out every two weeks. The BHRP with an 800 μm diameter fused-silica ball lens was able to obtain information on the subcutaneous fat in a totally non-invasive manner. Changes in the concentration of TL and TC during the treatment were analyzed, and the relationship between fat accumulation and dietary fat was studied...

Serotonin [5-hydroxytryptamine (5-HT)] is involved in both motor and sensory functions in hollow organs, especially in the gastrointestinal tract. However, the involvement of 5-HT in visceral sensation of the urinary bladder remains unknown. Because distention-induced ATP release from the urothelium plays an essential role in visceral sensation of the urinary bladder, we investigated the regulation of urothelial ATP release by the 5-HT signaling system. RT-PCR and immunohistochemical analyses of the urothelium revealed specific expression of 5-HT1D and 5-HT4 receptors...

INTRODUCTION: In 1931, Simpson et al. coined the term "peritoneal carcinomatosis" to describe the regional spread of ovarian tumors as localized or extended with involvement of the peritoneal serous membrane and neighboring anatomical structures. Research into the origin of peritoneal carcinomatosis is based on two phases in a woman's life: EMBRYO DEVELOPMENT: During week 3, the bilaminar disc becomes a trilaminar disc called the mesoderm. Inside the lateral plate mesoderm, the coelomic cavity is divided into 2 layers: the parietal (somatic) mesoderm, which gives rise to the parietal peritoneum and pleural surfaces; and the visceral (splanchnic) mesoderm, which gives rise to the visceral peritoneum, visceral surface of the pleura, gonadal stroma, and the muscular layer of the hollow viscera and its mesenteries...

Male internal genitalia of eriophyoid mites comprise cuticle lined (anterior genital apodeme, genital chamber and ductus ejculatorius) and soft (paired vasa deferentia and single testis) organs. Three-dimensional reconstructions based on autofluorescence show that a thin-walled genital chamber is usually situated in a transverse plane and precisely copies the shape of the spermatophore. A thin vertical longitudinal plate (homologous to female longitudinal bridge) joins the genital chamber and ventral genital cuticle...

OBJECTIVE: Acupuncture is increasingly used as an alternative to medical therapy for various pain conditions. To study the effect of acupuncture in experimental and clinical studies, a control condition with sham acupuncture is needed. However, as such models have not been established in assessment of acupunctures effect against visceral pain, this study aimed to validate a new method for blinded sham acupuncture in experimental rectal pain. METHODS: Fifteen subjects underwent a sequence of either sham or real acupuncture in randomized order...

The celiac axis (CA) and its branches are critically important arteries that supply blood to the vital solid and hollow abdominal viscera of the foregut. There are many potential anatomic configurations, with up to half the population having a variation from the classic pattern of the CA bifurcating into the hepatosplenic trunk and left gastric artery. These configurations result from permutations in the fusion of the paired dorsal aortas during the first trimester. Despite the short length of the CA, it is affected by a wide range of pathologic conditions, including mesenteric ischemia due to intrinsic occlusion (secondary to causes such as atherosclerosis or thromboembolic events) and extrinsic compression from masses or the median arcuate ligament...

INTRODUCTION: Pneumoperitoneum, observed by radiography, is typically associated with the perforation of hollow viscous. More than 90% of all cases of pneumoperitoneum are the result of a gastrointestinal tract perforation. These patients usually present with signs of acute peritonitis and require immediate surgical exploration and intervention. However, rare cases of idiopathic spontaneous pneumoperitoneum do occur without any indication of visceral perforation and other known causes of the free intraperitoneal gas...

Visceral pain has been defined as a pain resulting from activation of pain receptors localized in mucous membrane, serous membrane, and smooth muscles of hollow organs. The great majority of these organs are innervated by parasympathetic and sympathetic outflows. Afferent nerve fibres are involved in conduction of both acute and persistent pain and hyperalgesia. Visceral pain differs significantly from other types of pain in the way it originates and in clinical presentation. It can be misleading as a symptom, producing several problems in the diagnostic process...
