In this study of 64 cases of breast cancer with a clinical follow-up period of more than 5 years, several prognostic factors were evaluated. The purpose of this study was to determine whether any one parameter or group of parameters serves as adequate predictors of tumor behavior and patient's prognosis. Several prognostic factors included clinicopathological variables (patient's age, histologic grade, status of lymph node (LN) metastasis, and tumor size), expression of estrogen receptor (ER), progesterone receptor (PR), p53, bcl-2 and CD44 by immunohistochemistry, and DNA ploidy pattern. The results showed that the expression of ER and PR had a significant inverse correlation with the histologic grade (ER, p=0.05; PR, p<0.05). The expression of p53 protein showed a significant relationship with high histologic grade of tumor (p<0.05). The expression of bcl-2 protein was preferably seen in low histologic grade of tumor (p<0.05) and significantly associated with ER positive or PR positive tumors (ER, p<0.05; PR, p<0.05). This results suggest that bcl-2 protein might play significant roles in ER and PR. The CD44 expression showed a significant relationship with tumor size (p<0.05). The large size and aneuploidy pattern of tumor had a tendency to be associated with shorter patient survival. Cox's multivariate analysis showed that overall survival was affected by LN metastasis because of the shorter survival in patients with LN metastasis. In conclusion, tumor size, DNA ploidy pattern, and LN metastasis were themselves significant predictors of breast cancer survival rate.

The retinoblastoma (Rb)/cyclin D1/p16 pathway is an important constituent of cell cycle regulation. Perturbations in this pathway due to a variety of genetic aberrations have been reported in many human cancers including breast cancer. We examined the significance of immunoexpression of p16 protein, cyclin D1 protein, Rb protein (pRb), and p53 protein in 128 cases of invasive breast carcinoma. The results were correlated with survival rate and clinicopathological variables, including age, histologic grade, lymph node status, tumor size, estrogen receptor (ER), and progesterone receptor (PR) content. Abnormal expressions of p16 and pRb which were defined as negative staining were seen in 21% and 43% of tumors, respectively. There was a significant inverse relationship between p16 and pRb expression. There was no correlation between p16 staining and any other parameters, including survival rate, cyclin D1, p53, and clinicopathologic variables. Surprisingly, there was a trend for tumors which were positive for pRb to be grade III ductal carcinomas. Cyclin D1 positivity was noted in 46% of cases. The expression of cyclin D1 protein was significantly higher in lower histologic grade, higher ER and PR expression. The expression of p53 protein showed a significant correlation with high tumor grade. In a Cox multivariate analysis, neither p16, pRb, cyclin D1 nor p53 was an independent predictor, but tumor size and lymph node status were independent predictors of patient outcome.

PURPOSE: To describe the appearance and average thickness of the internal anal sphincter with anal endosonography in healthy Korean adults. MATERIAL AND METHODS: 184 subjects(male: 96, female: 88) with no history of anorectal disease or surgery were studied with anal endosonography. The average thickness of internal sphincter was meas ured at the mid-anal canal. For the internal sphincter, which is often asymmetric, the thickness of each 4 part(12, 3, 6 and 9 o'clock direction) were measured in left lateral decubitus position. RESULTS: The anal wall was well visualized in 5 layers(mucosa, submucosa, internal anal sphincter, intersphincteric plane, external anal sphincter) with anal endosonography. The anal endosonogram showed the internal anal sphincter as a homogenous, well-defined, hypoechoic, circular band, and slightly asymmetric. The average thickness of the internal anal sphincter in the area of mid-anal portion was 2.0 0.3 mm(range: 1~3 mm). There was no sexual difference; however, a significant positive correlation with age was found in average thickness of the internal anal sphincter. The correlation with lean body mass was not found. CONCLUSION: The internal anal sphincter is well-visualized, best defined structure by anal endosonography. Average thickeness of the sphincter in Korean appeared to be the same as in the Western.

C-erbB-2 oncoprotein has been known to act as growth factor receptor responsible for the regulation of cellular growth, proliferation and differentiation and has been demonstrated in a number of cancers by immunohistochemical as well as matrix blotting techniques. Breast and ovarian cancer patients, whose tumor cells have amplification or overexpression of this oncoprotein, have been suggested to have worse prognosis. Yet, there are only a few studies on c-erbB-2 oncoprotein expression in transitional cell carcinoma(TCC) of the bladder. The aim of this study was to examine c-erbB-2 oncoprotein expression in bladder cancer to assess its potential as a useful prognostic marker in transitional cell carcinoma of the bladder. Deparaffinized tumor specimens from 42 patients with TCC of the bladder and 3 normal bladder tissue specimens were utilized. C-erbB-2 oncoprotein expression was detected by immunohistochemical analysis and then correlated with conventional prognostic variables such as histologic tumor grade, stage and DNA ploidy. In addition, we related the expression of c-erbB-2 oncoprotein to indicators of cellular proliferative activities such as proliferating cell nuclear antigen(PCNA), mean number of silver nucleolar organizer regions(AgNORs) per nucleus, flow cytometric S-phase fraction(CPF) and proliferation index(PI). The incidence of c-erbB-2 oncoprotein expression in Ash grade IV TCC of bladder was higher than that in Ash grade II and III (Chi-square test, p<0.05). The incidence of positive immunoreaction was higher in cases with muscle invasion and metastasis than in superficial tumors with statistical significance(p<0.05). In addition, statistical significant correlation was noted between c-erbB-2 oncoprotein expression and PCNA expression rate. But there were no significant differences in c-erbB-2 oncoprotein expression to DNA ploidy, PI nor SPF by flow cytometry and mean number of AgNORs per nucleus. The results of this study suggests that the c-erbB-2 oncoprotein together with other predictive parameters may serve to provide a phenotypic profile which permits more accurate forecasting of bladder cancer behavior and may prove to be useful in the future as an important guide to specific anti-tumor therapy.

During the rehabilitation period, traumatic fracture of the lower extremity in chronic spinal cord injured patients may be occur frequently. In the past, conservative treatment with pillow or plaster splinting was advocated by many clinician, but its treatment is still controversial. This paper presents our experience with fracture of 20 patients(5.7%) of total 350 patients who had spinal cord injuries from Jan. 1980 to Mar. 1987 at Korea Veterans Hospital. The results were as follow. 1. The incidence of fracture was not related to age, sex, type and duration of spinal cord injury. 2. The most common cause of fracture was insignificant trauma(94%). 3. The distribution of fracture was in the following order of frequency;supracondyle of femur (20%), shaft of femur (20%), shaft of tibis (16%). 4. The methods of treatment-Twenty cases were treated by conservative treatment and eleven cases were treated by operative treatment in following order; paster splint with well padded; 9 cases (20%), pillow splint; 4 eases (13%), plate and screw; 3 cases (10%). 5. Total 11 cases of complications were 8 cases in conservative treatment and 3 cases in operative treatment. 6. The duration of bone union was average 10 weeks in nonoperative treatment and average 10.2 weeks in operative treatment. Treatment should strive to achieve fracture healing with minimal danger to the patient and should cause little or no interfrence with patient's daily routine.

BACKGROUND: The perfect preanesthetic medication and its ideal route of administration are still debated. Transmucosal administration of midazolam has been of interest because of the rapid, reliable onset of action, predictable effects and avoidance of injections. Because many medications are well absorbed from the mucosa, we conducted a randomized, prospective, blinded study to compare acceptance and efficacy of intranasal and sublingual administration of midazolam as a preanesthetic medication in children. METHODS: One hundred twenty eight patients aged 0.5-12year were stratified by age: 38 infants and toddlers, 0.5-3yr; 48 preschoolers, 3.1-7yr; and 42 school age, 7.1-12yr. They were randomized to received 0.2 mg/kg of midazolam in the nose or under the tongue. Hemoglobin oxygen saturation by pulse oximetry and sedation score were recorded before drug administration, at 2.5min intervals for 15min, at separation from parents and during induction with enflurane in O2. Retention time of sublingual drug and duration of crying were recorded. RESULTS: The incidence of crying at the time of administration of midazolam was greater following intranasal compared with sublingual administration(60% vs 17%, p<0.05). Within age groups, only infants and toddlers showed a significant difference in the incidence of crying between treatment groups. Significant changes in sedation occured in both groups from 2.5min after administration. CONCLUSIONS: Sublingual midazolam is better accepted than intranasal midazolam as a preanesthetic sedative in children.

Congenital hypoprothrombinemia is a rare congenital coagulation defect. The clinical signs are manifestation of generalized tendency such as; mucosal bleeding, hypermenorrhea and post tooth extraction hemorrage. It is associated with prolongation of PT and PTT with normal thrombin time and decreased serum prothrombin level. A case with congenital hypoprothrombinemia was experienced by the authors. A 36 days old male baby was admitted with palor skin and vomiting started one day before admission. Right side brain parenchymal hemorrhage and left shift of lateral ventricle were on brain CT scan. Prologation of prothrombin time and partial prothrombin time with decreased serum prothrombin level were resulted. Serum factor I, V, VII, VIII, IX and X were within normal level. We report a case congenital hypoprothrombinemia with a brief review of relaed literatures.

Injury of diaphragm mainly occur in penetrating, crush and blunt injuries to the lower chest or upper abdomen, and it is most often secondary to automobile accidents. Diaphragmatic rupture is most frequent in blunt chest trauma and the rate is below 1% of them. Traumatic rupture of the diaphragm is responsible for the herniation of abdominal viscera. Physical finding and radiographic sign of diaphragmatic hernia is nonspecific and misreading. Therefore, the diagnosis of traumatic rupture of diaphragm may be difficult during the early period after the injury, especially when clinical features are dominated by associated injuries. Emergency surgical management is necessary when it is complicated with serious complication. We experienced the case of traumatic diaphragmatic hernia detected after the operation of femur fracture. The patient was injured by motor vehicle accident 6 days before the operation of the femur fracture. There was no specific symptom and sign and the manifestation of the diaphragmatic hernia. in radiographic studies until operation of the femur fracture was done. Diaphragmatic hernia was confirmed by chest X-ray and arterial blood gas analysis after operation of the femur fracture. The repair of the diaphragmatic hernia was directly performed after the diagnosis. The prognosis was favorable, and she was discharged to ward from intensive care unit after 1 day of operation. We must consider the possibility of traumatic diaphragmatic hernia in the patient who have the history of blunt chest or abdominal trauma.

One of the goals of anesthesia is complete, comfortable and rapid recovery without sequelae from anesthesia. We compared the recovery pattern between anesthesia with propofol and thiopental/isoflurane. The fifty patients undergoing emergency appendectomy were allocated randomly to receive one of the anesthesia with propofol or thiopental/isoflurane. All of the patients were also given fentanyl, atracurium in equivocal dosage per weight and 50% N2O. Group 1(patient No; 25) was received anesthesia with fentanyl, atracurium, N2O and continuous injection of 6~12 mg/kg/hour of propofol. Group 2(patient No; 25) was received anesthesia with thiopental, fentanyl, atracurium, N2O and 1~2 MAC(minimal alveolar concentration) of isoflurane. We studied the duration of return of self respiration from discontinuation of anesthetics and recovery pattern in time sequence. The results were as following; The group 1 compared with group 2 at early recovery phase. 1) The duration of return of self respiration from discontinuation of anesthetics retured more rapid. 2) Emergence time was more rapid. 3) Postoperative sequelae(nausea, vomiting, sedation, drowsiness, memory dysfunction, pain) rate was less severe. But at recovery phase after 24 hours, there were no significant difference in postoperative sequelae and recovery condition in both groups. Therefore, we concluded that propofol is better than thiopental/isoflurane for anesthesia of emergency appendectomy in view of early recovery pattern.

10.Fracture of the penis: results of early surgical treatment.
Korean Journal of Urology 1991;32(3):428-430
Rupture of the corpus cavernosum, commonly referred to as penile fracture, is an unusual urologic emergency. Nine patients were treated surgically among ten patients with fracture of the penis between January 1987 and February 1991. Follow up was obtained in nine. During follow up they were achieving normal, painless erections or normal marital relations. One patient developed a slight penile curvature but this did not affect his sexual activity. In view of these good results, including a short hospital stay, low morbidity and early return to full sexual activity, early surgical treatment is strongly recommended in patients with fracture of the penis.
