Cystic Shape Cemento-Ossifying Fibroma of Ethmoid Sinus.

Cemento-ossifying fibromas are a group of rarely occurring benign tumours, developing from the periodontal membrane and varying considerably in appearance and in the progress of the disease. Their common feature is higher or lower production of cemental tissue. In most cases the tumours are small because their cementoma mature quickly and become inactive, which causes the tumour to stop growing.

Posttraumatic Stress Disorder and Orofacial Pain.

Chronic orofacial pain occurs frequently in patients with posttraumatic stress disorder (PTSD) and at the same time any pathological process involving orofacial area can be reflected in emotional interpretation of pain and can trigger a series of reactions associated with the PTSD group of symptoms in patients with PTSD. Painful stimuli caused in this way may occur after the primary cause ceased, and because of convergence can cause referred pain outside of the anatomical site where the primary injury occurred. Chronic orofacial pain and PTSD are diagnosed on the basis of subjective testimony and this regularly occurs in the context of social interaction between patients, doctors, medical staff or researchers making it difficult to standardize the results and introduces many cultural phenomena.

Impact of posttraumatic stress disorder on sinonasal symptoms and quality of life in patients with chronic rhinosinusitis.

Background: Severity of chronic rhinosinusitis (CRS), measured by disease-specific health-related quality-of-life questionnaires, is expected to increase in patients who also suffer from posttraumatic stress disorder (PTSD). Altered pain perception, sleep disorders, and fatigue may be associated with this comorbidity.

Methods: Severity of CRS was compared between a group of 28 patients with CRS and a group of 28 patients with CRS and concomitant PTSD using different disease-specific and generic instruments, such as visual analog scale (VAS), Short Form-36 test (SF-36), and Sino-Nasal Outcome Test-22 (SNOT 22).

Giant congenital nevus with plexiform neurofibroma and malignant peripheral nerve sheath tumor.

A female patient with a giant congenital nevus associated with plexiform neurinoma and malignant peripheral nerve sheath tumor (MPNST) on head and neck is presented. We theoretically discuss possibilities of mutual origin all three entities, including the Boland theory of neurochristopaty. The clinical, surgical, and histologic aspects of the disease are discussed.

Thermography-measured effect of capsaicin, methylprednisolone and mitomycin on the survival of random skin flaps in rats.

Aims: This study was designed to determine if steroids, capsaicin and mitomycin improved skin flap survival in rats, and it has confirmed that thermography is an effective method to measured skin flap vitality.

Methods: Forty female Wistar rats were randomised into four groups. A standardised full thickness inferiorly based dorsal random-pattern skin flap was raised, and a gelatine sponge was placed before suturing between the flap and its recipient bed, soaked with 0.

Prolonged esophagitis after primary dysfunction of the pyloric sphincter in the rat and therapeutic potential of the gastric pentadecapeptide BPC 157.

Seven or fourteen days or twelve months after suturing one tube into the pyloric sphincter (removed by peristalsis by the seventh day), rats exhibit prolonged esophagitis with a constantly lowered pressure not only in the pyloric, but also in the lower esophageal sphincter and a failure of both sphincters. Throughout the esophagitis experiment, gastric pentadecapeptide BPC 157 (PL 14736) is given intraperitoneally once a day (10 microg/kg, 10 ng/kg, last application 24 h before assessment), or continuously in drinking water at 0.16 microg/ml, 0.

An experimental model of prolonged esophagitis with sphincter failure in the rat and the therapeutic potential of gastric pentadecapeptide BPC 157.

We report a simple novel rat model that combines prolonged esophagitis and parallel sphincters failure. The anti-ulcer gastric pentadecapeptide BPC 157, which was found to be stable in gastric juice, and is being evaluated in inflammatory bowel disease trials, is an anti-esophagitis therapy that recovers failed sphincters. Twelve or twenty months after the initial challenge (tubes sutured into sphincters for one week and then spontaneously removed by peristalsis), rats exhibit prolonged esophagitis (confluent hemorrhagic and yellowish lesions, thinner epithelium and superficial corneal layer, with stratification derangement); constantly lowered pressure of both sphincters (assessed by using a water manometer connected to the drainage port of a Foley catheter implanted into the stomach either through esophageal or duodenal incision); and both lower esophageal and pyloric sphincter failure.
