Intracranial nerve sheath tumors unrelated to the cranial nerve roots are extremely rare, and the origin of the tumors are debatable. We report a case of pathologically-proven neurofibroma inside the lateral ventricle. A 49-year-old man presented with headache of 6 months duration, urinary incontinence, visual disturbance and right hemiplegia. Brain CT scan showed a well defined isodense mass with homogenous contrast enhancement and marginal calcification. At surgery the tumor was found to be a 4cm-sized lobulated mass attached only to the choroid plexus. Histologically, the tumor masses consisted of fasciculating bundles of wavy spindle cells, with a considerable collagen laydown.

BACKGROUND: This study is aimed to elucidate the developmental pattern of human fetal lip by histological and immunohistochemical examinations. METHODS: Totally 231 normal human lip tissues obtained from autopsied fetuses were fixed with 10% buffered formalin, sectioned in cross and longitudinal directions, routinely stained for H&E and performed for immunohistochemistry with antibodies of S-100 protein, proliferating cell nuclear antigen (PCNA), transglutaminase C (TGase-C), metalloproteinase (MMP)-3, MMP-10, tenascin, KL1, K8.12, E-cadherin, tissue inhibitors of matrix metalloproteinase (TIMP)-1, TIMP-2 and total keratin (TK). RESULTS: The lip structure first appeared as an orifice of stomodeum around the 7-8th week of gestation, and a major structure of the midface was observed by the 11-12th week. As the squamous epithelium of the lip became thick and was keratinized, the vermilion border became distinguished in the 15-16th week, and the lip structure was almost completed with the presence of orbicularis oris muscle in the lingual side of vermilion border by the 17-18th week. Immunohistochemically, the vermilion border showed strong reactions for tenascin, E-cadherin and MMP-3 and increased positivity for PCNA, cytokeratins (TK, KL1, K8.12), and TGase-C. CONCLUSIONS: With the above findings we suppose that the cytodifferentiation of vermilion border epithelium plays an important role for the development of human fetal lip.

Fingerprints have been used for personal identification, for revealing physical anthropological characteristics, and for diagnosing genetic disorders. Morphology of fingerprints has been analyzed in various tribes. However, in Korean, the analytical methods of fingerprints and the numbers of subjects were not sufficient to find standard values for Korean fingerprints. In this study, fingerprints of 3216 Koreans (2095 males and 1121 females) were analyzed using the various methods and compared with those of other tribes to contribute in revealing physical anthropological characteristics of Korean and also in diagnosing genetic disorders of Korean. The results were as follows. 1. The incidence of ulnar loop type, whorl type, radial loop type, and arch type was 50.4%, 42.9%, 3.8%, and 2.9%, respectively. Data from the comparison of the incidences of fingerprint types in Korean with those in various tribes lead us to conclude that Korean belongs to the Asians and becomes closer to the Whites and Blacks in which loop type is frequent and whorl type is not frequent. 2. Fingerprint type seems to be related to the strength of finger since whorl type was frequent in male and in right hand, and arch type was frequent in female and in left hand. In addition, loop of fingerprint appears to have the tendency to open to the side bearing more physical contact since radial loop type was frequent in second finger, and ulnar loop type was frequent in fifth finger. 3. Among the subtypes of fingerprint, morphologically simple types were common. Among the subtypes of arch types, simple arch type with the same number of radial dermal ridges as ulnar ones was the most common. Among the subtypes of loop types, ulnar loop type without concentric circles or spirals was the most common. Among the subtypes of whorl types, concentric whorl type without loops was the most common. 4. Finger ridge counts were 16.9, 13.9, 11.9, 11.3, and 11.2 in first, fourth, third, second, and fifth finger, respectively; and were greater in male than in female. Finger ridge counts are greater in fingers which shows whorl type. However, there would be other factors to determine finger ridge counts; for examples, the size and behavioral habit of finger.

1. The intracranial pressure (ICP) was raised by the extradural balloon method in urethane-anesthetized rabbits, and change of the arterial blood pressure (BP) with change of ICP was studied. 2. In the control rabbit group raising ICP resulted in marked increase in BP. 3. In the reserpine-treated group raising ICP did not induce the increase in BP but the decrease in BP. 4. In the tetrabenazine-treated group raising ICP did not cause change in BP. 5. After the administration of norepinephrine through the lateral ventricle to the reserpine-treated and tetrabenazine-treated rabbits, raising ICP resulted in marked increase in BP. 6. These results indicate that the existence of norepinephrine in the brain is essential for the BP increase by raising ICP.

Castleman's disease is a benign disorder characterized by hypervascular lymphoid hyperplasia. The etiology of the disease is still unknown. Although it may occur at the various sites such as peritoneum, retroperitoneum, pelvic lymph node, muscle and lung, it occurs most commonly at the mediastinum. Even though specific pathophysiologic relations are still not clearly determined between two different histologic types -hyaline vascular type and plasma cell type-, there were several previous reports dealing with the plasma cell type transformed or progressed into different types of malignancies such as malignant lymphoma, Kaposi's sarcoma and Hodgkin's disease. We experienced a case of plasma cell type Castleman's disease that transformed into a malignant lymphoma and report this case with review of literatures.

BACKGROUND: Multiple Antigen Simultaneous Test (MAST)-immunoblot assay is a practical and economical test, which has been recently introduced nationwide. Authors investigated test efficiency of a MAST-immunoblot assay, Polycheck Allergy (PA). METHODS: A total of 3,153 patients were tested by PA and the results were compared with the results of ImmunoCAP and skin prick test (SPT) in 532 and 75 patients, respectively. The correlation with the lgE results measured by VIDAS was also analyzed. RESULTS: The agreements of PA with SPT were 87.8% in the Inhalant Panel and 89.3% in the Food Panel and the agreement of ImmunoCAP with SPT was 95.2%. The most common allergens giving positive reactions were Dermatophagoides farinae (46.2%) and Dermatophagoides pteronyssinus (40.0%). SPT taken as a reference, PA compared with ImmunoCAP showed higher agreement (D. farinae, 76.0 vs. 70.7%; D. pteronyssinus, 76.0 vs. 74.4%), sensitivity (D. farinae, 72.7 vs. 68.2%; D. pteronyssinus, 75.0 vs. 71.2%) and specificity (D. farinae, 85.0 vs. 81.3%) except for the specificity for D. pteronyssinus (78.3 vs. 87.5%). The rate of allergen specific IgE positive patients was higher than that of negative patients when total IgE was over 100 kU/L. CONCLUSIONS: Our results showed that the agreement, sensitivity and specificity of PA were similar to or better than those of the previously established test, ImmunoCAP. The allergen specific IgE results of PA were in correlation with total IgE. PA may be used for testing allergen specific IgE to diagnose and treat allergic diseases.

The upstream stimulatory factor 1 (USF1) gene has been shown to play an essential role as the cause of familial combined hyperlipidemia, and there are several association studies on the relationship between USF1 and metabolic disorders. In this study, we analyzed two single nucleotide polymorphisms in USF1 rs2073653 (306A>G) and rs2516840 (1748C>T) between the case (dyslipidemia or obesity) group and the control group in premenopausal females, postmenopausal females, and males among 275 Korean subjects. We observed a statistically significant difference in the GC haplotype between body mass index (BMI) > or =25 kg/m(2) and BMI <25 kg/m(2) groups in premenopausal females ( chi-square=4.23, p=0.04). It seems that the USF1 GC haplotype is associated with BMI in premenopausal Korean females.

The nephrotic syndrome in association with extrarenal malignancy is not an uncommon event. The membranous nephropathy is most frequently associated with various carcinomas of the lung, breast, stomach and colon. Though the exact causal relationship has not been determined completely, deposition of the immune complexes composed of antitumor antibody and tumor antigens in the subepithelium is most favorably accepted. We experienced a patient with previously diagnosed membranous nephropathy and subsequently demonstrated early gastric cancer during patient follow-up. After surgical resection proteinuria improved significantly. All physicians are strongly recommended to examine thoroughly and search carefully for possibility of concomitant occult malignancy when an aged patient, especially over 40 years old, is diagnosed as a nephrotic syndrome.

OBJECTIVE: To evaluate risk factors for massive lymphatic ascites after laparoscopic retroperitoneal lymphadenectomy in gynecologic cancer and the feasibility of treatments using intranodal lymphangiography (INLAG) with glue embolization. METHODS: A retrospective analysis of 234 patients with gynecologic cancer who received laparoscopic retroperitonal lymphadenectomy between April 2006 and November 2015 was done. In June 2014, INLAG with glue embolization was initiated to manage massive lymphatic ascites. All possible clinicopathologic factors related to massive lymphatic ascites were determined in the pre-INLAG group (n=163). Clinical courses between pre-INLAG group and post-INLAG group (n=71) were compared. RESULTS: In the pre-INLAG group (n=163), four patients (2.5%) developed massive lymphatic ascites postoperatively. Postoperative lymphatic ascites was associated with liver cirrhosis (three cirrhotic patients, p<0.001). In the post-INLAG group, one patient with massive lymphatic ascites had a congestive heart failure and first received INLAG with glue embolization. She had pelvic drain removed within 7 days after INLAG. The mean duration of pelvic drain and hospital stay decreased after the introduction of INLAG (13.2 days vs. 10.9 days, p=0.001; 15.2 days vs. 12.6 days, p=0.001). There was no evidence of recurrence after this procedure. CONCLUSION: Underlying medical conditions related to the reduced effective circulating volume, such as liver cirrhosis and heart failure, may be associated with massive lymphatic ascites after retroperitoneal lymphadenectomy. INLAG with glue embolization can be an alternative treatment options to treat leaking lymphatic channels in patients with massive lymphatic leakage.
