PURPOSE: Numerous methods exist for diagnosing nonpalpable testis in treatment of cryptochidism. However, there is no clinically established data for the rational diagnostic tool of nonpalpable testis in terms of expenses. We tried to establish a current conventional diagnostic course of nonpalpable testis. We then evaluated the efficacy of ultrasonography, physical examination under general anesthesia and laparoscopy for diagnosing nonpalpable testis. METHODS: Between March 2000 and February 2005, 103 boys(129 testes) with undescended testes were treated in our department. There were 31 testes(24.0%) that were not palpable at physical examination. These patients were evaluated with ultrasonography and repeated physical examination under general anesthesia. In the cases where testes could not be detected with ultrasonography and physical examination under general anesthesia, laparoscopy was performed to diagnose nonpalpable testis. RESULTS: In 31 cases of nonpalpable testis, 13 testes were detected with ultrasonography and 15 testes became palpable with physical examination under general anesthesia. All of the remaining 16 nonpalpable testes were confirmed with laparoscopy. CONCLUSION: Physical examination under general anesthesia was superior to ultrasonography in making a diagnosis of nonpalpable testis. Ultrasonography and physical examination under general anesthesia could reduce the incidence of diagnostic laparoscopy. Therefore, it is recommended that ultrasonography, physical examination under general anesthesia and laparoscopy must be performed conventionally in order to diagnose nonpalpable testis.

BACKGROUND: Valve replacement in children has many problems such as the durability of prosthetic valve, thomboembolism and hemorrhage. But recently, the necessity of valve replacement in children increased and the above problems were solved party. So the number of valve replacement in children increased progressively. RESULTS: Valve replacement in 47 children were done at Seooul National University Chidren's Hospital from March 1986 to July 1991. The patients were composed of 25 males and 33 females. 25 patients had congenital heart disease and 22 patients rheumatic heart disease. 45 patients received single valve repalcement, 2 patients double valve repalcement, and among all of them, 2 patients redo-replacement. The major valve lesion was mitral insufficiency and post-operative status in view of NYHA functinonal class was improved in most patients. The mechanical valves were applied to 45 patients and tissue valves to 2 patients. The indication of valve replacement were progressive increase in ventricular volume, major regurgitant fraction over grade III decrease in exercise tolerance and vegetation. The overall early mortality was 8.5% and late mortality 0%. There were post-operative complication rate of 30% and late complication rate 14%, and among the later, valve faliure was reported in 2 pantients and thromboembolism in 1 patient. The complication-free rate was 97.7% at post-operative 1 month, 91.3% at 12 months, 90% at 36 months and 60% at 48 months. 43 patients received anticoagulation and/or antiplatelet therapy, but there was no critical indication for this. CONCLUSION: These results suggest that cardiac valve replacement in children have been effective therapeutic modality even though various problems still remain, but we propose that sufficient long-term follow-up and clinical research be needed.

The adenocarcinoma of appendix and fallopian tube are both very rare. The incidence rate for fallopian tube is less than 1% of all genital malignancies. Fallopian tubes have been very rarely associated with synchronous tumorigenesis, and to the authors knowledge, the combination of mucinous adenocarcinoma of appendix has never been previously reported. The authors experienced a extremely rare case of synchronous adenocarcinoma of appendix and fallopian tube in 56 years old female patient who has suffered for 10days from RLQ abdominal pain. Pathologic examination of the resected specimen revealed a synchronous mucinous type adenocarcinoma of vermiform appendix and fallopian tube.

BACKGROUND: Adenocarcinoma arising in the body or tail of the pancreas tends to be metastasized at the time of diagnosis, is mostly in inoperable stage, and poor in prognosis. In this study, we evaluated the adenocarcinoma arising in the body or tail of the pancreas and investigated the prognostic factors and ideal treatment. MATERIAL AND METHODS: We retrospectively analyzed 33 patients who were cytologically or histologically confirmed as adenocarcinoma in the body or tail of the pancreas at Samsung Medical Center from October 1994 to December 1999. RESULTS: The mean age of the patients in the resectable and unresectable groups were 63.4 and 60.6 year-old, respectively. The mean CA19-9 level was higher in unresectable group (5166.2u/ml), compared to the resectable group (964.7u/ml).(p=0.039) In the resectable group, the body was the most common location of the tumor, and in the unresectable patient group, the tail was more prevalent.(p= 0.021) The mean survival time of the resectable group was 15.1months. The univariate analysis of the resectale group showed that the age, sex, lymph node metastasis, chemotheraeutic modalities, radiotherapeutic modalities, and the location of tumor were not significantly related with the prognosis. In unresetable group, the mean survival time was 6.4months. The mean survival time were 3.3 months in patients over 60 year-old and 9.9 months in patients less than 60, showing statistically significant difference.( p=0.007) The mean survival time were 12.2 months and 3.4 months in patients who received the chemotherapy and who did not, respetively.(p=0.004) Evaluating the relationship between the extent of metastasis and survival, the mean survival length of single metastasis was 9.3 months, showing significantly higher survival length compared that of multiple metastasis.(p=0.027) Patient's sex, radiotherapeutic modality and location of the tumor were not significantly related with the prognosis. Multivariate analysis of prognostic factor showed that the patietnt's age (p=0,842), the extent of metastasis( p=0.458), and chemotherapeutic modality (p=0.078) were unrelated with prognosis. CONCLUSION: In adenocarcinoma arising in the body and tail of the pancreas, the CA19-9 level and tumor location could be utilized as indicating factors of the operability of the tumor. Age, sex, lymph node metastasis, and location of the adenocarcinoma are not significantly related with the survival length in both the resectable and unresectable groups. Also, in both groups, the chemotherapeutic and radiotherapeutic modalities were not related with the survival length.

A 70-year old man presented with postprandial upper abdominal pain of two months duration, accompanied by indigestion, weight loss, and anorexia. There was no abnormality noted in the lab results. Abdominal CT showed a 3-cm round cystic mass in the tail of the pancreas. A distal pancreatectomy was done. The patient was discharged in 9 days. The cystic wall was composed of a keratinizing squamous epithelium surrounded by subepithelial, dense lymphoid tissue. Some clusters of the sebaceous gland were noted but there was no sweat gland or hair follicle. These findings were consistent with a lymphoepiethelial cyst with sebaceous differentiation. The patient was followed up for 12 months post operatively, and no recurrence was noted.

PURPOSE: This study aimed to evaluate the clinical course and prognostic factors of acquired third, fourth, and sixth cranial nerve (CN) palsy grouped according to etiology. METHODS: This study involved a retrospective review of the medical records of 153 patients who were diagnosed with acquired paralytic strabismus from January 2004 to July 2015. Outcomes, recovery rates, and time to recovery were investigated according to the affected CN: CN3, CN4, and CN6 palsies. The patients were classified into four groups based on etiology: idiopathic, traumatic, neoplastic, and vascular. RESULTS: The mean age of the patients was 59.8 ± 14.5 years and the mean follow-up period was 10.8 months. Out of the 153 patients, 63 (41.2%) had CN3 palsy, 35 (22.9%) had CN4 palsy, and 55 (35.9%) had CN6 palsy. The most common causes were vascular related (54.9%), followed by idiopathic (28.1%), trauma (8.5%), and neoplasm (5.88%). About 50% of the patients recovered within six months. Among the four etiologic groups, the idiopathic group showed the best prognosis because about 50% of the patients in this group recovered within three months. This was followed by the vascular, traumatic, and neoplastic groups. Cox proportional hazard analysis revealed a significant association between the baseline prism diopter and recovery rate. CONCLUSIONS: The prognosis and natural history of paralytic strabismus vary depending on its cause. The vascular group had the best recovery rate and shortest recovery time, whereas the neoplastic group required the longest time to recover.

Stress induced cardiomyopathy is a disease that shows a dysfunction of the ventricle, but it can be rapidly reversible. It often occurs in older women primarily who suffers from emotional or physical stress. There are some case reports about postpartum stress induced cardiomyopathy. Most of the patients are recovered naturally within days to weeks. We report a case of a 37 years-old woman, who had experienced postpartum stress induced cardiomyopathy 8 years ago, revisited hospital because of cardiomyopathy after secondary delivery. Herein we report a rare case of recurrent stress induced cardiomyopathy after secondary normal vaginal delivery.

OBJECTIVES: Since the 1990s, drug-resistant bacteria have become common pathogens of hospital-acquired infections. In recent years, healthcare-associated infections have come to the fore, and it is reported that distribution rates of these bacteria are comparable to those of hospital-acquired infections. However, there have been few studies on differences in resistant bacteria depending on the size of hospitals. Thus, the authors studied differences in drug-resistant bacteria between a tertiary hospital and smaller medical institutions. METHODS: We retrospectively analyzed the clinical findings and sputum culture results of patients transferred from tertiary hospitals (group A, n=74) and those transferred from smaller medical institutions (group B, n=65). RESULTS: The number of patients with malignancy was higher in group A than in group B. The length of intensive care unit stay was longer in group A than in group B. Antibiotic therapy and mechanical ventilation were more frequently used in group A than in group B. There were no significant differences between the 2 groups in bacterial species (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa) and their resistance rates to carbapenem, while there were significant differences between the 2 groups in the bacterial species (Acinetobacter baumannii) and its resistance rate to carbapenem. CONCLUSION: In this study, there were significant differences between the 2 groups in the bacterial species and resistance rates to carbapenem for A. baumannii infection unlike other bacterial infections. Further studies on risk factors and patient classification are needed to confirm our results.
