Three cases of human embryo of Carnegie stage 13 were described. The CR length of these embryos were 3.0-5.3mm. The authors made a reconstruction model using photograph, photocopy and computer. These embryos were characterized externally by 4 limb buds and 4 pairs of branchial arches, and internally closed otic pits, appearance of venous valves, septum primum and foramen primum in the heart, beginning of the right and left lung buds, appearance of lens disk.

PURPOSE: Inidence of recurrent common duct stones reported approximately 20% for a second operation, and with even higher rate following subsequent reoperation. However, the factors contributing to recurrent stones have not well defined. Some authors have reported on association of juxtapapillary diverticula with recurrent biliary stones. We have studied to assess the clinical significance of coexisting PAD on recurrent common bile duct stones and to establish the rational operative procedure in primary or recurrent common duct stones with coexisting PAD. METHODS: Medical records of 456 consecutive patients (Feb. 1993~Aug. 2002) who performed ERCP for biliary symptoms were reviewed. We comparative study retrospectively have done between patients with and without PAD on recurrence of common duct stones and outcome of treatment. RESULTS: Incidence of PAD was 15.1% on ERCP, and increased in the old aged patients. Incidence of biliary stone in PAD group was higher than that of non-PAD group (73.9% vs. 50.6%), and gall stone involving common duct was more prevalent in PAD group than non-PAD group. PAD group showed higher stone recurrence rate (23.5% vs. 6.1%) and earlier recurrence following conventional treatment, and needs more multiple treatments, compared with non-PAD group. Intradiverticular papillae (IDP) type showed higher stone recurrence, compared with juxtapapillary diverticula (JPD) type (36.8% vs. 15.6%). CONCLUSION: PAD would be one of important contributing factors for development and recurrence of common bile ductstones. So rational operative procedure for primary or recurrent common duct stones with coexisting PAD should include extirpation of PAD, particulary in IDP type.

Pneumothorax was recognized as a potential hazard of mechanical ventilation after tracheal intubation. Excessive pressure the trachea during general anesthesia could produce lung rupture and pneumothorax. The incidence of pneumothorax has increased as a result of increased application of invasive diagnostic and therapeutic procedures. Emphysematous bleb rupture afterlaryngospasm, bronchospasm, or cough may be causes of pneumothorax. Tension pneumothorax during anesthesia is often difficult to diagnosis, but it needs prompt dignose and treatment. We experienced 3 cases of tension pneumothorax during and after general anesthesia.

BACKGROUND: Detection methods for ABO antibody (Ab) titers vary across laboratories, and the results are different depending on the method used. We aimed to compare titer values using different detection methods for the measurement of ABO Ab titers. METHODS: For ABO Ab detection, pooled group A or B red blood cells (RBCs) were reacted with each of 20 sera from blood groups A, B, or O without dithiothreitol treatment. The room-temperature (RT) incubation technique and the indirect antiglobulin test (IAT) were used in the tube test and gel card test. Flow cytometry (FCM) was performed by using anti-IgM and anti-IgG Abs. RESULTS: Regardless of the blood groups tested, the FCM assay with anti-IgM showed the highest titer compared to the tube test and gel card test with RT incubation in both. The tube test with IAT showed a higher titer than the gel card test with IAT (Gel-IAT) or FCM with anti-IgG in blood group A and B, while Gel-IAT showed the highest titer relative to the other tests, only for the anti-A Ab in blood group O. CONCLUSIONS: There were significant differences in the titers depending on the detection method used, and each method showed a different detection capacity for each ABO Ab depending on the ABO blood group tested. Therefore, caution should be exercised in interpreting ABO Ab titer results, taking into consideration the detection method used and the blood group.

A ‘collision’ tumor refers to the existence of two different neoplasms within the same tumor. Sometimes, the term ‘biphasic tumor’ is also used. However, a ‘collision’ tumor is defined as the occurrence of two neoplasms within proximity of each other yet maintaining distinctly defined, separate boundaries. In contrast, a ‘biphasic’ tumor demonstrates two or more phenotypically distinct neoplastic cell populations merging within the same space. Here, we report a case of collision tumor associated with sarcomatoid eccrine porocarcinoma and basal cell carcinoma arising in a 57-year-old male patient.

The incidence of lung cancer and its mortality rate are increasing in Korea. At the time of diagnosis, 40% patients of lung cancer patients had metastatic lesions. The common metastatic sites are the contralateral lung, bone, liver, adrenal gland and the brain. Metastasis to oral mucosa is rarely encountered in lung cancer and metastasis to the gingiva is more uncommon. Approximately 1% of malignant carcinomas in the oral cavity are the result of metastases, and 10-25% of metastatic cancers originate from lung cancer. Clinically metastatic gingival lesions are benign including hemangioma, pyogenic granuloma, giant-cell granuloma or a peripheral fibroma. Often metastases to the gingiva are diagnosed too late and by the time they are detected, they have metastases to other organs. Here we report a case of small cell lung carcinoma that had metastased to the gingiva with review of relevant literature.

Because castration-resistant prostate cancer (CRPC) does not respond to androgen deprivation therapy and has a very poor prognosis, it is critical to identify a prognostic indicator for predicting high-risk patients who will develop CRPC. Here, we report a dataset of whole genomes from four pairs of primary prostate cancer (PC) and CRPC samples. The analysis of the paired PC and CRPC samples in the whole-genome data showed that the average number of somatic mutations per patients was 7,927 in CRPC tissues compared with primary PC tissues (range, 1,691 to 21,705). Our whole-genome sequencing data of primary PC and CRPC may be useful for understanding the genomic changes and molecular mechanisms that occur during the progression from PC to CRPC.
