The changes of electroencephalogram(EEG) in patients with dementia are most commonly studied by analyzing power or magnitude in certain traditionally defined frequency bands. However because of the absence of on identified metric which quantifies the complex amount of information, there are many limitations in using such a linear method. According to chaos theory, irregular signals of EEG cal also result from low dimensional deterministic chaos. Chaotic nonlinear dynamics in the EEG can be studied by calculating the correlation dimension. The authors have analyzed EEG epochs from three patients with dementia of Alzheimer type and three matched control subject. The result showed that patients with dementia of Alzheimer type had significantly lower correlation dimension than non-demented controls on 12 channels. Topographic analysis showed that the correlation dimensions were significantly lower in patients with Alzheimer's disease on frontal, temporal, central, and occipital head regions. These results show that brains of patients with dementia with dementia of Alzheimer type have a decreased complexity of electrophysiological behavior. We conclude that the nonlinear analysis such as calculating correlation dimension can be a promising tool for detecting changes in the complexity of brain dynamics.

Hepatoid carcinoma is a rare type of malignant tumor resembling hepatocellular carcinoma that arises in extrahepatic sites.(stomach, lung, ovary, pancreas, bladder and renal pelvis). Hepatoid carcinoma of the ovary is an extremely rare ovarian tumor, first described by Ishikura and Scully in 1987. Histologically it is important to differentiate this entity from other oxyphil tumors of the ovary as it requires aggressive treatment. We have experienced a case of hepatoid carcinoma of the ovary in 69-year-old postmenopausal woman, who has been treated with operation and adjuvant Taxol - cisplatin chemotherapy. We present this case with brief review of literatures.

Case histories of isolated and complete volar dislocation of the carpal scaphoid have rarely been reported .We report here another such case. On examination, the wrist was moderately swollen and tender over its volar aspect. Radiographs showed isolated, complete volar dislocation of the scaphoid. We used open reduction with K-wire fixation as treatment. After four weeks of operative reduction the patient had undertaken neurolysis due to median nerve compression symptom (carpal tunnel syndrome). At six weeks, the K-wires were removed and the patient was allowed to do a range of motion exercise. Twenty months after injury, the wrist was asymptomatic and had a mid-range of active motion without instability. There was no roentgenographic evidences of scapholunate dissociation or avascular necrosis

Extraperitoneal inguinal endometriosis often presents as an inguinal mass in women of reproductive age, Approximately 40 cases of inguinal endometriosis have been documented in the sutgical and gynecological literature. The overall incidence is in the range of 0.4% of patients with endometriosis. The right side is much more commonly involved than the left (almost 90% of the time in one series of 23 patients), and rarely is the condition bilateral. The most frequent complaint of patients with inguinal endometriosis is an inguinal mass, followed by pain and enlargement of the mass near menstruation. Authors have experienced two cases of endometriosis of the extraperitoneal portion of the round ligament of uterus and report with a brief literature review.

Primary sarcomas of the uteriae cerrix are exceedingly rare neoplasms. They comprise less than 1 percent of all cancers, with an incidence of 0.2 to 0.4 percent of those originating in the cervix. Indeed, only 19 cases of primary cervical leiomyosarcomas have been reported in the English literature. We have recently experienced one case of leiomyosarcoma arising from the cervix in a 40-year-old woman. Therefore, we the case with a brief review of the literature.
