The deletion 9p syndrome is a well characterized syndrome with about one hundred cases having been reported. Most patients have dysmorphic facial features, cardiac anomalies, and mental retardation. We report on a female infant with micrognathia, corneal opacity, cleft palace, cardiac anomaly, left polycystic kidney, and deletion 9p. Chromosome analysis and fluorescence in situ hybridization (FISH) showed her to have a derived chromosome 9 inherited from a maternal t(9;16) (p22;p13.2) by adjacent I segregation There are few reports of this particular chromosome rearrangement. We review deletion Sp syndrome.

Parovarian cysts constitute 10% of adnexal masses. They were found in broad ligament and mostly arise from mesothelium and less commonly from paramesonephric element and rarely from mesonephric element. In most cases parovarian cysts were asymptomatic. So, they were found incidentally at surgery for other conditions. Torsion is infrequent and it is difficult to distinguish it from torsion of other adnexal masses, appendicitis, etc. Recently, we experienced a voluminous parovarian cyst undergoing torsion, 25 cm in diameter. The case is presented with a review of literature.

The Reconstructive techniques of palatal defect are palatal island flap, palatal mucoperiosteal expansion, buccal flap, tongue flap, pushback palatoplasty, free flap and so on. We report a reconstruction of palatal defect using palatal flap. Excellent results were obtained by palatal connective tissue island flap and split thickness pedicle flap. Healing of defect occured rapidly. There were no postoperative complications except dull pain.

PURPOSE: The purpose of this study was to find the predictors for successful arthrocentesis for anterior disc displacement without reduction(ADD without Reduction) of the temporomandibular joint (TMJ). PATIENTS AND METHODS: Arthrocentesis and lavage was carried out in 25TMJs of 22patients whose MRI findings were all anterior disc displacement without reduction. The effectiveness of the treatment was evaluated in terms of the postoperative range of maximal mouth opening (MMO) and the degree of postoperative pain score. Predectors which was analyzed were age, duration of painful locking, MMO, the degree of pain, perioperative clicking and the amounts of irrigation fluid. RESULTS: 18cases (72%) was included to criteria for success. There were no significant differences in age, duration of locking, MMO and the degree of pain statistically. But In 15cases(83%) of successful cases, amouts of irrigated solution recovered to normal MMO were less than 150ml. And In 8cases (44%) of successful cases, perioperative clicking was appeared. CONCULSION: Amounts of irrigated solution recovered to normal MMO and the appeareance of perioperative clkicking may be predictors of the successful results of arthrocenetesis of ADD without reduction of TMJ.

PURPOSE: To determinate the effect of clinical factors on the duration of hematuria after transurethral resection of the prostate (TURP). PATIENTS AND METHODS: Seventy-three men who underwent TURP were analyzed retrospectively to determine the time of cessation of hematuria. The effect of various clinical factors (weight of tissue resected, operation duration, and resection rate) was assessed. RESULTS: Microscopic hematuria ceased in 37%, 70%, 87%, and 96% of patients at the end of the second, fourth, sixth, and eighth weeks, respectively. The duration of postoperative bleeding was significantly associated with the weight of tissue resected and the operation time (p<0.014 and <0.001, respectively). CONCLUSIONS: Postoperative hematuria usually stopped within 4 weeks of TURP. This period was directly related to the size of the gland resected and the duration of the procedure.

PURPOSE: To observe the histopathological changes in the periodontal tissues of mandibular molars in streptozotocin-induced diabetic rats after irradiation. MATERIALS AND METHODS: The male Sprague-Dawley rats weighing approximately 250 gm were divided into four groups: control, diabetes, irradiation, and diabetes- irradiation groups. Diabetes mellitus was induced in the rats by injecting streptozotocin. Rats in the control and irradiation groups were injected with citrate buffer only. After 5 days, the head and neck region of the rats in irradiation and diabetes-irradiation groups were irradiated with a single absorbed dose of 10 Gy. All the rats were sacrificed at 3, 7, 14, 21, and 28 days after irradiation. The specimen including the mandibular molars were sectioned and observed using a histopathological method. RESULTS: In the diabetes group, osteoclastic activity was observed in the alveolar bone and the root throughout the period of experiment. Also, osteoblastic and fibroblastic activities were markedly decreased. In the irradiation group, the osteoclasts were observed in the alveolar bone and the dilated capillaries were increased in the early experimental phases. However, vigorous osteoblastic activity was noted in the late experimental phases. In the diabetes-irradiation group, osteoclastic activity in the alveolar bone and the root was observed in the early experimental phases. However, there were no resorption and osteoblastic activity in the alveolar bone and the root in the late experimental phases, and obvious atrophic change of fibrous tissues was noted. CONCLUSION: This experiment suggests that osteoblastic activity was caused by irradiation in the late experimental phases, but atrophic change of the periodontal ligament tissues was induced after irradiation in diabetic state.

The objective of the present study is to obtain information on the hemodynamic characteristics in the anastomotic sites of femoral artery through the vascular implantation. Three dimensional steady and physiological blood flows in the femoral artery are simulated using the finite volume method. The geometrical shape of the anastomotic sites is made based on the vascular anatomy of a white rabbit. Wall shear stress distributions in the anastomotic sites for the physiological flow are compared with those for steady flow. Blood flow phenomena in the anastomotic sites of the femoral artery are discussed extensively.

The hemodynamic characteristics of the cuff end-to-side anastomosis model are investigated using by the finite volume predictions. The flow rates and the impedance indices through of the cuff anastomosis model are compared with those of the anastomosis model without the cuff. Blood flow increased through the cuff anastomosis model than the standard anastomosis model. The impedance index decreased with the increase of flow rate. The impedance index at a given flow rate is reduced by the increase of anastomosis angle and further reduced by the addition of the cuff. The results suggest that the cuff anastomosis model should be applied for the low Reynolds number flow and/or the small artery anastomosis model.
