Spontaneously ruptured uterine angioleiomyoma

Angioleiomyoma is an uncommon type of leiomyoma of the uterus that originates from smooth muscle cells and contains thick-walled vessels. A 45-year-old woman with the complaint of lower abdominal pain was admitted to the hospital. In the operation a ruptured, bleeding uterine tumor was seen. She underwent total hysterectomy and bilateral salpingo-oophorectomy. On pathologic examination of the specimen, the tumor was diagnosed as angioleiomyoma. Here, an unusual clinical presentation of uterine angioleiomyoma was reported.

Expression of NF-κB in Helicobacter pylori Infection

Helicobacter pylori colonizes the gastric mucosa in humans and causes chronic gastritis. NF-κB has a key role as a mediator in mucosal inflammation. In this study, we examined the expression of NF-κB in the antral epithelial cells of H. pylori-infected and H. pylori-uninfected biopsies and examined these processes in relationship with grade and activity of gastritis, density of H. pylori, presence of the intestinal metaplasia, and atrophy.Fifty biopsies (35 H. pylori-positive patients and 15 H. pylori-negative controls) were studied. NF-κB immunohistochemical stain was performed. NF-κB activity in H. pylori-infected biopsies were markedly enhanced compared with uninflamed biopsies (P = 0.001). We also found positive correlation NF-κB expression with severity of gastritis (according to Sydney score) (P = 0.001), activity of gastritis (P = 0.046) and H. pylori load (P < 0.001), and atrophy (P = 0.004). We did not find a significant relationship between NF-κB and the presence of intestinal metaplasia (P = 0.355). These findings suggested that expression of NF-κB has an important role in H. pylori gastritis.

Adenomatoid Ameloblastoma in the Mandible and Maxilla: Report of a Case

Ameloblastoma is an infrequent odontogenic neoplasm located in the mandible and/or infratemporal fossa extending into the maxilla. The authors report a patient who underwent a total of five operative interventions for recurrent lesions involving mandible and infratemporal fossa at other institutions before admission to our hospital. Radiographic imaging in our case demonstrated a solid/multicystic recurrent lesion of the right infratemporal fossa extending into the maxilla. Gross total excision of the tumour was done and the postoperative course was uneventful. In any case with a tumour located in this region, it is important to be aware of this condition because this lesion is unusual but serious pathology as illustrated in this report.
