Malignant mixed miillerian tumor (MMMT) was one of the rare uterine sarcoma. This tumor is composed of sarcoma and carcinoma. Primary MMMT in the peritoneum is among the rarest sites for MMMT. MMMT is highly malignant and the prognosis is grave due to frequent recurrence and metastasis. In the world literature, only 22 cases with primary MMMT of the peritoneum have been reported and most of these were single report. We report one case of primary MMMT in the peritoneum with a brief review.

The hypervariable short tandem repeat (STR) locus D12S391 was investigated in a Korean population. A total of 14 alleles were detected by size under denaturing conditions in 517 unrelated individuals. To confirm all of the alleles detected in a Korean population, a total of 34 fragments were sequenced. Prior to allele designation, we constructed the allelic ladders containing 11 alleles sequenced in this study. Allele 18 is the most common with a frequency of 0.281 in Koreans, and one variant allele 19.3 which have been confirmed by sequencing, was detected. The observed heterozygosity, the power of discrimination (PD), and the mean exclusion chance (MEC) for the locus D12S391 is 0.781, 0.946 and 0.652, respectively. No deviation from Hardy-Weinberg equilibrium was observed in a Korean population (p=0.557). In the 424 meioses in 105 Korean families confirmed using other 17 STR loci, no mutation was detected in locus D12S391. The STR locus D12S391system is useful both for the analysis identification and parternity.

A 37-year-old female presented with a conjunctival mass discovered 3 years prior. An excisional biopsy revealed a patternless proliferation of round and spindle-shaped cells with an eosinophilic fibrillary cytoplasm and vesicular nuclei with occasional inclusions. Psammoma bodies were arranged around the dilated irregularly-shaped vessels. Differential diagnoses included conjunctival solitary fibrous tumor (SFT), nevus, glomangioma, ectopic meningioma, and mesectodermal leiomyoma. The tumor cells were immunoreactive for CD34, CD99, bcl-2 and vimentin, and were negative for smooth muscle actin, desmin, glial fibrillary acidic protein, S-100 protein, epithelial membrane antigen, and human melanoma black-45. Ultrastructurally, the tumor cells had rough endoplasmic reticulum, free ribosomes, and scattered mitochondria without basal lamina or cellular junctions, which are features of fibroblasts. A diagnosis of SFT was rendered based on the light microscopic, immunohistochemical, and electron microscopic findings. We report here on the second case of a SFT arising in the conjunctiva, which clinically and histologically mimics conjunctival nevus, glomangioma, ectopic meningioma, and a hybrid neurogenic-myogenic tumor such as mesectodermal leiomyoma.

Allele-and genotype frequencies of the two short tandem repeat (STR) loci, HumFGA and D21S11, were determined in Korean population(n=196). DNA typing was accomplished by applying fluorescence-labeled PCR products and a differently labeled sequenced allelic ladders, followed by automated analysis using ABI 377 automatic sequencer and GeneScan 2.02 software. Prior to typing, allelic ladder of each locus was constructed with a combination of all alleles occuring from the population sample. A total of 15 alleles and 48 genotypes with the heterozygosity of 0.854 for HumFGA, and 12 alleles and 33 genotypes with the heterozygosity of 0.787 for D21S11 are observed in a population of 196 genetically unrelated individuals. No deviations from Hardy-Weinberg equilibrium were observed(p=0.753 for HumFGA, p=0.262 for D21S11). The data presented here (power of discrimination and average power of exclusion) show that both STR Loci, HumFGA and D21S11, are very informative for individualization from criminal evidences, and are also useful for parentage testing.

Occipital neuralgia is a form of headache that involves the posterior occiput in the greater or lesser occipital nerve distribution. Pain can be severe and persistent with conservative treatment. We present a case of intractable occipital neuralgia that conventional therapeutic modalities failed to ameliorate. We speculate that, in this case, the cause of headache could be the greater occipital nerve entrapment by the obliquus capitis inferior muscle. After steroid and local anesthetic injection into obliquus capitis inferior muscles under fluoroscopic and sonographic guidance, the visual analogue scale was decreased from 9-10/10 to 1-2/10 for 2-3 weeks. The patient eventually got both greater occipital neurectomy and partial resection of obliquus capitis inferior muscles due to the short term effect of the injection. The successful steroid and local anesthetic injection for this occipital neuralgia shows that the refractory headache was caused by entrapment of greater occipital nerves by obliquus capitis inferior muscles.

BACKGROUND/AIMS: There have been only a few endoscopic studies of lower intestinal lesions of malignant lymphoma. The aims of this study were to classify the ileocolonic lymphomas according to the colonoscopic findings and to reveal the clinicopathological relationship according to the classes. METHODS: Subjects were 24 cases of ileocolonic lymphomas. We evaluated the clinicopathological features according to their endoscopic findings. RESULTS: The chief complaints were abdominal pain, bleeding, and abdominal mass. Twenty-six lesions from 22 patients, excluding 2 multiple lymphomatous polyposis, were endoscopically classified as follows: fungating (10 lesions), ulcerofungating (7 lesions), infiltrative (5 lesions), ulceroinfiltrative (3 lesions), and ulcerative (1 lesion). The location of the lesions was the terminal ileum in 11 lesions, the colon in 10 lesions, and both regions in 5 lesions. Within the large bowel, the cecum was involved most frequently, followed by the ascending colon and the remainder. Most of pathological types were the diffuse large cell and the large cell immunoblastic. There was no relationship between the endoscopic findings and the histologic types. Eight cases were manifested as intussusception. CONCLUSIONS: Ileocolonic lymphomas can be classified endoscopically into five types. Among the types, fungating and ulcerofungating types are the most frequent.

BACKGROUND: Several types of three-dimensional (3D)-printed tracheal scaffolds have been reported. Nonetheless, most of these studies concentrated only on application of the final product to an in vivo animal study and could not show the effects of various 3D printing methods, materials, or parameters for creation of an optimal 3D-printed tracheal scaffold. The purpose of this study was to characterize polycaprolactone (PCL) tracheal scaffolds 3D-printed by the 4-axis fused deposition modeling (FDM) method and determine the differences in the scaffold depending on the additive manufacturing method. METHODS: The standard 3D trachea model for FDM was applied to a 4-axis FDM scaffold and conventional FDM scaffold. The scaffold morphology, mechanical properties, porosity, and cytotoxicity were evaluated. Scaffolds were implanted into a 7 × 10-mm artificial tracheal defect in rabbits. Four and 8 weeks after the operation, the reconstructed sites were evaluated by bronchoscopic, radiological, and histological analyses. RESULTS: The 4-axis FDM provided greater dimensional accuracy and was significantly closer to CAD software-based designs with a predefined pore size and pore interconnectivity as compared to the conventional scaffold. The 4-axis tracheal scaffold showed superior mechanical properties. CONCLUSION: We suggest that the 4-axis FDM process is more suitable for the development of an accurate and mechanically superior trachea scaffold.

BACKGROUND: Hand eczema is one of the most common skin disorders and negatively affects quality of life. However, a large-scale multicenter study investigating the clinical features of patients with hand eczema has not yet been conducted in Korea. OBJECTIVE: To identify the prevalence of various hand diseases, which is defined as all cutaneous disease occurring in hands, and to investigate the clinical features of patients with hand eczema and the awareness about hand eczema in the general population and to compare the prevalence of hand eczema between health care providers and non-health care providers. METHODS: To estimate the prevalence of hand diseases, we analyzed the medical records of patients from 24 medical centers. Patients were assessed by online and offline questionnaires. A 1,000 from general population and 913 hand eczema patients answered the questionnaire, for a total of 1,913 subjects. RESULTS: The most common hand disease was irritant contact dermatitis. In an online survey, the lifetime prevalence of hand eczema was 31.2%. Hand eczema was more likely to occur in females (66.0%) and younger (20~39 years, 53.9%). Health care providers and housewives were the occupations most frequently associated with hand eczema. Winter (33.6%) was the most common season which people experienced aggravation. The 63.0% and 67.0% answered that hand eczema hinders their personal relationship and negatively affects daily living activities, respectively. CONCLUSION: Hand eczema is a very common disease and hinders the quality of life. The appropriate identification of hand eczema is necessary to implement effective and efficient treatment.

BACKGROUND: Since the bioavailability of itraconazole capsule is influenced by patients gastric acidity, it results in treatment failure due to its low dissolution and subsequent low absorption when administered in fasting. Itraconazole Melt-Extrusion tablet has been lately developed in order to improve its dissolution profile. It is the first clinical study to evaluate the efficacy and safety of itraconazole Melt-Extrusion tablet in Korea. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of itraconazole melt-extrusion tablet 400mg daily for 1 week(pulse therapy) for hyperkeratotic type of tinea pedis and manus. METHODS: A clinical and mycological investigation was made of 812 outpatients with hyperkeratotic type of tinea pedis and/or tinea manus who had visited at 52 general hospitals under the lead of the Korean Dermatological Association from June to December, 1998. Patients confirmed by clinically and microscopically as hyperkeratotic type of tinea pedis and/or tinea manus were administered 2 tablets twice a day for one week and followed up for 8 weeks from the start of the medication. RESULTS: The results were summarized as follows; 1. Clinical symptoms of hyperkeratotic type of tinea pedis and/or tinea mauns were significantly improved at the end of study, week 8(p<0.001). 2. Clinical response rate, defined as more than 50% decrease of the sum of the clinical symptom scores, was 79.3%(512/646). 3. Mycological cure rate, dafined as both culture and KOH negative at week 8, was 78.2%(244 /312). 4. 40(5.5%) patients, of the 727 patients evaluable for drug safety evaluation, were reported to have adverse event. CONCLUSION: Itraconazole Melt-Extrusion tablet 400mg/day for 1 week (pulse therapy) is effective and safe in the treatment of hyperkeratotic type of tinea pedis and/or tinea manus.
