Two cases of suprasellar papillary craniopharyngioma are presented. The tumors are exclusively composed of well-formed papillary squamous epithelium and show morphologic homogeneity. There is no palisading basal layer in squamous epithelium. Clinical and radiologic findings, exclusive occurrence in adult and lack of calcification, are much different from conventional craniopharyngioma. Differences between papillary craniopharyngiom and conventional craniopharyngioma are discussed.

Glassy cell carcinoma is an unusual neoplasm of the uterine cervix with highly aggressive clinical behavior. On cervico-vaginal smear examination, the tumor has well confused of atypical repair cell of the endocervix. Recently, we have experienced two cases of glassy cell carcinoma of the uterine cervix, diagnosed on cervico-vaginal smears and confirmed on following histologic sections. The cervico-vaginal smears revealed abundant clusters with well defined boarders. The cell clusters were composed of large tumor cells. The tumor cells had distinct granular cytoplasm and eosinophilic macronucleoli. Characteristic cytologic features of this tumor were discussed in view of differential diagnosis.

Thallium-201 brain SPECT is utilized in the diagnosis of brain tumor especially in cases where CT or MRI findings alone cannot differentiate malignant lesion from benign. Recently we came across two cases of positive T1-201 brain SPECT in clinically suspected brain tumor patients that turned out to be hemorrhagic cerebral infarction instead on biopsy. The findings in these cases demonstrate that thallium-201 accumulation may occur by the breakdown of the blood-brain barrier and phagocytic cell infiltration in the liquefaction stage of infarction.

To investigate the role of the p53 gene in the development of endometrial adenocarcinoma and to study the relation between alteration of the p53 gene and histologic grade, the author studied the alteration of thep53 gene in hyperplastic lesions and adenocarcinomas of the uterine endometrium. The study was carried out with immunohistochemical stain and PCR-SSCP. The materials included ten cases of endometrial hyperplasia (five simple and five atypical complex) and 18 cases of endometrial adenocarcinoma. Overexpression of the p53 protein were found in one of five atypical complex hyperplasias (20%) and 11 of 18 adenocarcinomas (61.1%). The intensity of p53 overexpression appeared to have increasing tendency with higher histologic grade of adenocarcinomas. Among the II cases of adenocarcinoma that overexpressed p53 protien, five cases (45.5%) were found to have mutations by PCR-SSCP. One was grade 1 (20%), two were grade 11 (25%), and two were grade III (40%). The sites of mutation were three exon 8, one exon 5, and one exon 6. In conclusion, alteration of the p53 gene may paly a role in the development of endometrial adenocarcinoma and appears to occur as a late event in carcinogenesis.HHowever, inactivation of the p53 gene in early stage of tumor development cannot be excluded.

One of the strenuous problems in orthodontic procedures is postretention stability and retention against relapse. Many investigative trial had been done to disclose the factors associated with relapse and effective prescription to stave off, however, the nature of these jeopardies remained obscure. The objective was to investigate the long-term stability and quantitative changes of dental arches subsequently after Class I nonextraction treatment Study models,cephalometric headfilms of 26 samples which were taken before, after teatment and postretention were employed to measure the interdental width of corresponding buccal teeth,overbite,overjet and the inclination of incisors and molars. Statistical analysis was carried to compare each measurements across the time period, and followings were brought around 1. The quantitative amount of relapse in overbite presented positive correlation with the amount of changes through the treatment. 2. Stability of intercanine width was so far secure in the case the expansion had been done through. 3. The amount of changes in intercanine width of the lower regardless of expansion or contraction manifested less than the upper, however, the relapse ratio got high. 4. The upper !and lower incisors were likely to be labioversive, and remained stable after retention. 5. The first molars of the upper and lower were conceivably tipped back immediately after treatment and returned to the original angulation. The expansion of intermolar width stayed stable across the time scheme after treatment It was suggested that the maintenance of intercanine width of lower was pertinent to perform the postretention stabilityv and the expansion of dental arch shoed be confined within physiologic boundaries of the patients.

Fat Embolism is a rare complication of multiple long bone fracture or extensive soft tissue injury. The pathogenesis of fat embolism has been poorly understood and still its definite pathogenesis, diagnosis and treatment were not fully established. Recently fat embolism considered as a post traumatic respiratory failure. Monitoring of blood gas is required for early diagnosis and respiratory supportive treatment with continued minitoring is necessary until resolution. Fifteen cases of fat embolism treated at from September 1979 to October 1981 Eul Ji General Hospital were clinically analized. Among the fifteen cases, fourteen were recovered without sequalae and one was expired ten days after trauma.

OBJECTIVE: It has been known that the posterior pedicle screw fixation provides good mechanical stability in unstable burst fracture. But, posterior fixation without anterior column support may not be adequate to withstand the axial load and to keep the corrected kyphotic angle. We present results of one stage fixation by posterior approach in unstable burst fracture. METHODS: Nine patients with unstable burst fracture were treated with posterior fixation and intervertebral fusion using titanium mesh cages and pedicle screws. The canal decompression was achieved by laminectomy and partial pediculectomy through the posterior approach. In all cases, the short segment fixation and anterior column support with cage were performed on the one stage operation. RESULTS: Of nine patients, seven was satisfied with excellent clinical results except two cases of the Frankel's grade A. All patients had good stabilization of spinal column and enough decompression without any neurological complications. It was possible to maintain the corrected kyphotic angle with the circumferential stabilization(three column fixation). CONCLUSION: The anterior and posterior column fixation through the posterior approach provides good stability and decompression in the patients with unstable burst fracture.

Anastomotic leakage (AL) after colorectal surgery is a significant concern, as it can lead to adverse functional and oncologic outcomes. Numerous studies have been conducted with the aim of identifying risk factors for AL and developing strategies to prevent its occurrence, thereby reducing the severe morbidity associated with AL. The intraoperative method for reducing AL includes a mechanical assessment of AL, an assessment of bowel perfusion, drain placement, and the creation of diverting stomas. The anastomosis technique is also associated with AL, and the appropriate selection and accurate application of anastomotic methods are crucial for preventing AL. Indocyanine green fluorescence imaging has recently gained popularity as a method for assessing bowel perfusion. While it is useful for detecting bowel perfusion, standardized protocols and measurement methods need to be established to ensure its reliability and effectiveness in clinical practice. The use of intraoperative drains to reduce AL has produced inconsistent results, and the routine adoption of this practice is not currently recommended. Diverting stomas can be used to help reduce the morbidity associated with AL. However, it is important to carefully consider the complications that can arise directly from the stoma itself. It should be noted that while a stoma can reduce AL, it cannot completely prevent it. This descriptive review examines various intraoperative methods aimed at reducing AL, discussing their effectiveness in reducing AL.
