OBJECTIVE: To estimate the predictive value of initial serum B-hCG and progesterone measurement for pregnancy outcome in IVF-ET. METHODS: Serum B-hCG at 11-12th day after embryo transfer and progesterone at 7th day after oocyte aspiration were measured in 48 successful pregnant IVF-ET cases from July 1993 to June 1997. RESULTS: Of 48 cases, 26 cases (54.2%) successfully carried to sustaining gestation and 22 cases (45.8%) failed to sustain gestation. The estimated initial serum B-hCG levels in the normal sustaining pregnancy group (132.28+ 22.42 mlU/ml) were statistical significantly higher than 29.43+8.08 mIU/ml in the failed sustaining pregnancy group (p<0.001), while the estimated initial serum progesterone levels showed no significant differences (p=0.159). In order to determine the predictive values using the Receiver Operator Curve (ROC), an appropriate cutoff value of 38 mIU/ml for initial serum B-hCG was obtained. In IVF-ET pregnancies, the estimated serum B-hCG levels in cases of chemical abortion in failed sustaining pregnancy were significantly lower compared to the normal sustaining pregnancy group (p<0.001). CONCLUSION: The initial serum B-hCG levels at 11 days after embryo transfer could be used to predict the pregnancy outcome in an IVF program. An initial progesterone level acquired on the 7th day after oocyte retrieval is not a useful indicator to predict pregnancy outcome.

BACKGROUND: In Korea, the prevalence of tuberculosis and hepatitis is high, and combined therapy with rifampicin and pyrazinamide is used in tuberculosis, so drug induced hepatitis is not only problem of tuberculosis therapy but also cause of treatment failure. However most of recent reports on drug induced hepatitis during antituberculosis medication have dealt with its pathogenesis and have stressed the biochemical, and histopathological aspects of the disorder, whereas this study was designed primarily to provide information on the clinical features. METHOD: The subjects of study were 1414 patients treated with antituberculosis drugs on the department of chest medicine at National Medical Center during the 5-year 6-month period from January 1, 1988, to June 30, 1993. Retrospective analysis of clinical features for the 29 patients who developed drug induced hepatitis was done. RESULTS: 1) The incidence of antituberculosis drug induced hepatitis was 2.1%. 2) Male to female ratio of antituberculosis drug induced hepatitis was 2:1, but case rates among males and females were not significantly different. 3) Rates of drug induced hepatitis according to age distribution shows the most common incidence between 35 to 49 year old age group, but rates among groups of age were not significantly different. 4) Drug induced hepatitis was most common in the case of moderate advanced Pulmonary tuberculosis(rate is 2.78%), but rates among types of tuberculosis were not significantly different. 5) 18 cases(62%) of antituberculosis drug induced hepatitis patients had no signs or symptoms. In remaining cases, they were nausea, vomiting, jaundice, hepatomegaly, icteric sclera, right upper quadrant -tenderness in order 6) 22 cases(76%) of antituberculosis drug induced hepatitis cases had occurred within the first month. 7) The duration of abnormal liver function was 28±5(Mean±SD), ranged from 5 days to 180 days. 8) One case of antituberculosis drug induced hepatitis died. 9) The levels of abnormal GOT ranged from 64 to 1055U/L and GPT from 68 to 931U/L. CONCLUSION: There are no decided predisposing factors of antituberculosis drug induced hepatitis, so it should be done biochemical monitoring as week as close monitoring for overt signs or symptoms of hepatitis to avoid the development of irreversible hepatic reaction, especially at the treatment of the first month.

Infantile digital fibromatosis(IDF) is a rare, benign fibrous tumor, first described in 1965 by Reye. IDF may occur single or multiple lesions exclusively on the fingers or toes, rare occurrence outside the digit have been reported. This tumor grow slowly and may adhere to the deeper tissue, and may lead to deformity of the digit, but do not distant metastasis or dissemination. There is a marked tendency for recurrence after surgical excision. Up to now, only 6 cases have been reported in the literature showing spontaneous regression. We experienced a case of infantile digital fibromatosis located on hypothenar area at birth. Also that spontaneous regressed at 13 months of age. We reported a case of IDF showing spontaneous regression with brief review of related literature.

PURPOSE: The purpose of this study was to investigate the effects of a mouthguard on stress distribution under mandibular impact. MATERIALS AND METHODS: The FEM model of head consisted of skull, maxilla, mandible, articular disc, teeth, and mouthguard. The impact locations on mandible were gnathion, the center of inferior border, and the anterior edge of gonial angle. And the impact directions were vertical, oblique (45degrees), and horizontal. The impact load was 800 N for 0.1 sec. RESULTS: When vertical impact was applied, the similar stress and the distribution pattern was occurred without the relation of the mouthguard use (P>.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the oblique (45degrees) impacts were happened. However, the stress was centralized on the teeth in the model without mouthguard (P<.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the horizontal impacts was occurred. However, the stress was centralized on the teeth without mouthguard (P<.05). For all impact loads, stress concentrated on maxillary anterior teeth in model without mouthguard, on the contrary, the stress was low in the model with mouthguard and distributed broadly on maxillary anterior teeth, facial bone, and skull. CONCLUSION: The mouthguard was less effective at shock absorbing when vertical impact was added. However, it was approved that mouthguard absorbed the shock regarded to the oblique (45degrees) and horizontal impact by dispersing the shock to the broader areas and decreasing the stress.

Although Crohn's disease is usually found in the ileum and colon, it can be located in the whole gastrointestinal tract from the oral cavity to the anus. The frequency of gastroduodenal Crohn's disease is rare and is reported to range between 0.5% and 4.0% in Crohn's disease. And when Crohn's disease does involve the upper gastrointestinal tract, there is nearly always concomitant disease in the small bowel and colon. Very rarely, isolated Crohn's disease of the stomach and duodenum may occur. Definite diagnosis requires histologic confirmation, however, endoscopic biopsies often fail to reveal granuloma. Thus, if absence of definite histologic findings, combining clinical, radiologic and endoscopic findings suggest this condition. We experienced a first case of Crohn's disease confined to stomach and reported with review of the literature.

PURPOSE: To determine the incidence of pseudolesions seen in the posterior aspect of segment IV of the liveron CT arterial portography(CTAP), and to evaluate the findings of CT hepatic arteriorgraphy(CTHA) and celiacangiography. MATERIALS AND METHODS: We retrospectively analysed 450 cases of patients who had undergone CTHA,CTAP and celiac arteriorgraphy for the diagnosis and treatment of hepatic lesion, and evaluated the incidence andimaging findings of pseudolesions in segment IV of the liver, as seen on CTAP, CTHA and celiac arteriography. RESULT: In 28 of 450 patients(6.2%), pseudolesions of focal perfusion defect were seen in segment IV on CTarterial portography. Pseudolesions were seen on CTAP on 39 different section slices ; these were wedge-shaped in41% of cases(16/39), rectangular in 30.8%(12/39), ovoid-shaped in 23.1%(9/39), and half moon-shaped in 5.1%(2/39); they were from 1 to 3cm(average, 1.5cm) in anteroposterior diameter, from 1 to 3cm(average, 1.9cm) in width, andfrom 1 to 4cm(average, 1.9cm) in craniocaudal diameter. Twenty-seven patients underwent CTHAs ; hyperattenuationwas seen in 13(48.2%), isoattenuation in 12(44.4%), and hypoattenuation in two(7.4%). In 19 of 28 celiacangiograms(67.9%), the right gastric artery was seen to arise from the hepatic artery, and aberrant right gastricveins directly draining into the left lobe of the liver were seen in three(10.7%). CONCLUSION: The incidence ofpseudolesion seen in segment IV of the liver on CTAP was 6.2% (28/450), and in 3 of 28 cases(10.7%), celiacangiography showed aberrant right gastric venous drainage. For pseudolesions, CTHA showed variable attenuation,and this modality is less sensitive than CTAP for the detection of pseudolesion.

Superior mesenteric artery (SMA) syndrome results from compression of the third portion of the duodenum by the superior mesenteric artery or one of its branches where this vessel crosses over the duodenum as it descends from the aorta. Recently 2 cases of SMA syndrome were experienced. A 43-year-old female and a 41-year-old male were admitted due to complaints of frequent postprandial abdominal distension and vomiting for 4 months. An UGI series and abdominal CT scan revealed distension of stomach and duodenum with a cut-off in the duodenal third portion. Both patients underwent duodenojejunostomy with successful symptom relief.

The majority of undiagnosed diaphragmatic ruptures are associated with a high mortality rate if not treated immediately. A high index of suspicion for diaphragmatic injury during initial evaluation is the most important factor. A case was experienced involving delayed presentation of a traumatic diaphragmatic hernia, in a 49 year old female injured in a road traffic accident a year prior to admission. She was admitted with complaints of left side chest pain, nausea, and vomiting for 7 days. She was diagnosed as a diaphragmatic hernia on her left side by several diagnostic tests including a gastroscopy and CT scan. Her medical history was carefully examined as well. Surgical repair was performed.
