Pineal gland is structured by special morphology of neural cells. The tumor originates from the gland or its surrounding tissnes therefore these tumors have histologically different origins. They are in deep location with narrow path inward. Pineal tumor has not specific symptoms and usually diagnosed lately. The removal surgery comfuses of 2 stages - first: brain ventricular-abdomen drainage, second: tumor removal within 2-3 weeks after the first stage. There are 5 methods to approach the tumor, with own advantages and short comings

On July 4th 2002 at the Department of Trauma and Burn, Can Tho General Hospital, an accidental total amputation of the left forearm in a 14 years old child was replanted successfully. Micro-surgery was initiated 2 hours after injury and lasting for 7 hours. Immediate results showed good survival signs of the replanted forearm. Further surgery on the bone of the arm and skin transplantation was performed. Rehabilitation is on going to regain the function of the forearm.

Study was performed on 48 subjects with inward deformity of elbow after a supracordylar fraction on the arm, form January 1999 to June 2002 at the Department of Surgery, National Institute of Pediatry. Results showed that this deformity was occurred commonly in children of 6-11 years old of age, especially in boys. Humeral ostectomy was indicated in the case of deformity of cubitus varus of > 15o and > 6 months after the trauma. The opening of the lower end of brachial bone and the campbell classical technique of excison of the muscle did not mineralize did not limit the motions of the joints of elbow. Kirschner screw was fixed temporarily and removed 12-14 days after the operation

Improved No8 plaster dressing was used in Thai Nguyen Centre Hospital from August 2001 to August 2002. Results were as follows: 56/56 subjects ahd good fixation without secondary dislocations, without other complications. After the procedure, shoulder joints got good movements. Good results were comfirmed by X-ray examinations

OBJECTIVE: The purposes of this study were to evaluate the relationship between the dental and basal arch forms; to analyze their differences in the tapered, ovoid, and square arch forms in normal occlusion by using three-dimensional (3D) virtual models; and to test the hypothesis that the overjet and maxillomandibular basal arch width difference have a significantly positive correlation. METHODS: Seventy-seven normal occlusion plaster casts were examined by 3D scanning. Facial axis (FA) and WALA points were digitized using the Rapidform 2006 software. The dimensions of the dental and basal arches and the overjet were measured. The samples were classified into 3 groups according to arch forms: tapered (n = 20), ovoid (n = 20), and square (n = 37). Analysis of variance (ANOVA) was used to compare the dental and basal arch dimensions. The Pearson correlation coefficients between the intercanine as well as the intermolar widths at the FA and WALA points were calculated. RESULTS: With regard to the basal arch dimensions, the tapered arch form showed a larger mandibular intermolar depth than the ovoid. Strong correlations were noted between the basal and dental intermolar widths in both the upper and lower arches (r = 0.83 and 0.85, respectively). Moderate correlation was found between the upper and lower intercanine widths (r = 0.65 and 0.48, respectively). CONCLUSIONS: The 3 dental arch form groups differed only in some dimensions of the skeletal arch. Moderate correlations were found between the basal and dental intercanine widths. These findings suggest that the basal arch may not be a principle factor in determining the dental arch form.

Fractures of the carpal navicular is a serious injury, particulary in a manual worker, because non union and the resultant disability may limit the usefulness of the extremity. There is almost unanimous agreement that fresh fractures of the carpal navicular should be treated by immobilization in a plaster cast and how immobilization should be maintained. As a result of this study we have arrived at several conclusion regarding to the conservative treatment of fresh navicular fracture.

Congenital dislocation of the knee is very rare skeletal deformity and was firstly described by Chatelaine in 1822. Since then there have been a few number of case reports and some series discussing the etiology and treatment. The tibia is displaced anteriorly in relation to the femur. It is generally subdassified as simple hyperextention, subluxation, and dislocation depending on the degree of the joint displacement and the severity of disease. Early gentle manipulation and serial splintage or plaster cast are recommended for treatment and were successful in the majority except the case of quadriceps contrarture or late correction. The authors experienced one case of congenital dislocation of the right knee and brief review of the related literatures was made.

BACKGROUND AND OBJECTIVES: This study aimed to gather three-dimensional data to detect fish bones as an esophageal foreign body model and to assess the possibility that this method could be applied for cases of real fish bone foreign body (FBFB). MATERIALS AND METHOD: Fish bones from two species were collected and sizes were measured. Pork meat loaf was placed flat into a plastic box containing plaster cast and bones were laid over the meat layer. Another layer of meat was placed on the bones, then another layer of plaster cast, and the final layer of meat were placed. The meat-bone sandwich was regarded as a fish bone foreign body model of esophagus. The model was imaged using computed tomography (CT) scan and the CT data were reconstructed three-dimensionally making multi-planar reconstruction, maximal intensity projection, and volume rendering images. We tried to find tools to detect the shape and lying position of the FBFB model. The above tools were applied to 3 FBFB cases to verify effectiveness of the tools. RESULTS: Multi-planar reconstruction, maximal intensity projection, and volume rendering images were reconstructed easily. After single or more processing, all of the bones could be detected. The shape and lying positions could be detected using tools made from FBFB models. CONCLUSION: Reconstructed images of CT data readily enabled the detection of fish bone in the esophageal model and real cases.
