Colorectoanal intussusception is a rare and distinct entity that differs from the more common rectal prolapse. Typically the intussusception occurrs with tumor at the apex of the intussuscepted segment acting as lead point. Here we present a case and review the literature of colorectoanal intussusception. The case presented here is that of an elderly woman with a proximal sigmoid colon cancer at its apex. Anterior resection was electively performed after reduction of the intussusception. It is important to differentiate a colorectoanal intussusception from the more common rectal prolapse because treatment may differ. The anorectum remains in its normal anatomic position in colorectoanal intussusception, whereas the anal canal is effaced with the prolapsed segment of bowel in rectal prolapse. Identification of a tumor at the apex of the intussuscepted bowel should also arouse suspicion that the condition is not a rectal prolapse.

Fractures of the body of the talus are extremely rare, constituting only about 0.1 percent of all fractures (Coltart 1952). Consequently, the prognostic problems have so far been elucidated only on the basis of few reports in the literature. The authors experienced an unusual type of the shearing fracture of the talar body with total disocation that the talar body was lying upside down in the ankle joint. Satisfactory results were obtained after follow up period of 20 months and some are reporting this case with bibliographic reviews.

We investigated the effect of 2% dorzolamide and 0.12% UF-021 on intraocular pressure and peripapillary and optic nerve head microcirclation with Heidelberg Retina Flowmeter. The 40 eyes of 40 normal subjects were divided 2 groups. 2% Borzolamide and 0.12% UF-021 were instilled in each group. The IOP and microcirculation of peripillary retina and optic nerve head were measured before and 90min, 4, 8, 12, 24 hours after instillation. The IOP was decreased at 90 minutes, 4, 8 hours after instillation of 2% dorzolamide and maximal reduction of IOP was observed at 90 minutes (P<0.05). The IOP was decreased at 90min, 4, 8, 12 hours after instillation of 0.12% UF-021 and maximal reduction of IOP was observed at 4 hours(P<0.05). But, there was no statistically significant changes of microciculation in both groups(P>0.05). We suggest that 2% dorzolamide and 0.12% UF-021 reduce the IOP, but do not alter the mictocirculation of peripapillary retina and optic nerve head.

Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. 82 cases of traumatic optic neuropathy were investigated to evaluate the effectiveness of high dose corticosteroid for the visual improvement. Age, sex, initial visual acuity, final visual acuity, interval to treatment, the type of trauma and the affected region were studied retrospectively.250 mg of Methylprednisolone was administered intravenously every 6 hours for 3 days, and then followed by tapering using oral prednisone The vision was improved in 36 of 82 cases[43.9%]. It was difficult to interpret the relation-ships between the affected region and visual improvement, the interval for each treatment and final visual acuity. However, the vision was improved in 45 of 50 cases who had an initial visual acuity of above light perception, but in the two of 32 cases with no light perception. If indicated, fifteen cases were treated with a combination of high dose corticosteroid and optic nerve decompression. In initial treatment of traumatic optic neuropathy, high dose corticosteroid was effecive. Whether or not initial visual acuity was better than light perception was a key risk factor in the outcome.

Statement of problem. Relatively low success rate of root analogue implant system was supposed to be due to the time duration between extraction and implant installation. The use of three-dimensional computer tomography and the reconstruction of objects using rapid prototyping methods would be helpful to shorten this time. Purpose. This aim of this study was to evaluate the application possibility of the 3-dimensional computer tomography and the rapid prototyping to root analogue implants. Material and methods. Ten single rooted teeth were prepared. Width and height of the teeth were measured by the marking points. This was followed by CT scanning, data conversion and rapid prototyping model fabrication. 2 methods were used; fused deposition modelling and stereolithography. Same width and height of this models were measured and compared to the original tooth. Results. Fused deposition modeling showed an enlarged width and reduced height. The stereolithography showed more exact data compared with the fused deposition modelling. Smaller standard deviation were recorded in the stereolithographic method. Overall width error from tooth to rapid prototyping was 7.15% in fused depostion modelling and 0.2% in stereolithography. Overall height showed the tendency of reducing dimensions. Conclusion. From the results of this study, stereolithography seems to be very predictable method of fabricating root analogue implant.

he Magnetic. resonance imaging has been used widely to evaluate the disk position without any interruption of the TMJ structures, and the dynamic MRI presenting computed serial imaging or the video-recorded simulation images is thought to be very effective to evaluate the disk position under function. This is to study the correlation between the clinical diagnosis and the findings of dynamic MRI for diagnosis of internal derangement of the 7 patients were examined clinically, and the movement of TMJ meniscus was reviewed in the dynamic MRI. MRI was very reliable to diagnose the amount of anterior displacement of articular disc, the structural abnormality of temporomandibular joint, the cause of functional limitation, and to differentiate the muscle related pain & dysfunction.
