PURPOSE: Spiculation pathologically correlated with irregular fibrosis, localized lymphatic spread of tumor, or an infiltrative growth pattern of tumor, and the spiculation was Observed in malignant mass. But the spiculation was also observed in benign mass, particularly in tuberculoma. We retrospectively reviewed the length of spiculation under the hypothesis that the length of spiculation could be one of differential diagnostic points between lung cancer and tuberculoma. MATERIALS AND METHODS: We studied thirty seven patients (27 men and 10 women) ranging in age from 35 to 80 years (mean, 60 years). Analysis of spiculation included (a) the number of spicules (b) the mean length of spicules (c) the mean length of the longest spicule (d) the percentage of the mean length of spicules to the longest diameter of mass (e) the percentage of the mean length of spicules to the shortest dia, meter of mass. RESULTS: The mean length of spicules of tuberculoma was 13.8 mm (S. D. 6.7) and that of lung cancer was 5.7 mm (S. D. 3.5). The percentage of the mean length of spicules to the longest diameter of tuberculoma was 63.6% and that of lung cancer was 13.7%. The percentage of the mean length of spicules to the shortest diameter of tuberculoma was 90.4% and that of lung cancer w~s 18.3%. CONCLUSION: It is hard to differentiate lung cancer from tuberculoma on the basis of the spiculation being present or not, but we suggest that the longer spiculation be more highly suggestive of tuberculoma rather than lung cancer. The length of spiculation may help us differentiate lung cancer from tuberculoma.

The idiopathic retroperitoneal fibrosis means that proliferation of fibrous tissue in the retroperitoneal cavity influences the aorta, inferior vena cava, psoas muscle and ureter, and its etiology is not found. Especially, when both ureters are compressed, hydronephrosis resulted in uremia are developed progressively, and it may be treated by urinary diversion. We report a case of idiopathic retroperitoneal fibrosis that treated by bilateral pyelo-ileo-neocystostomy and postoperative metabolic derangement that managed successfully with brief review of literature.

We report a case of naturally-occurring anti-Miltenberger (anti-Mia(a)) antibody in a 16-year-old man who had never been transfused before. During an operation for a trauma he received 2 units of packed red blood cells. He was negative on an antibody screening test, but positive a week after the surgery when an extended screening test was conducted using blood cells positive for Miltenberger III (Mi.III) phenotype. The Mi.III phenotype is a low incidence antigen among Caucasians, however, it is reported to be relatively high in incidence among people in South-East Asia. Anti-Mia(a) antibodies are clinically significant antibodies that cause hemolytic transfusion reactions (HTRs) and hemolytic disease of the newborns (HDNs). In addition, anti-Mia(a) has a high rate of incidence among Thais, Taiwanese, and Hong Kong Chinese. There has been no particular report on Koreans regarding the incidence of this antibody, it would therefore require further research on the Mi.III phenotype and anti-Mia(a).

Prevotella intermedia has been implicated as a potent pathogen in many kinds of periodontal, pulpal and periapical diseases. However, it has been isolated from periodontally healthy adults and from edentulous children as well. The intraspecies heterogeneity of Prevotella intermedia has been demonstrated in early studies and finally Shah & Gharbia confirmed the existence of 2 DNA homology groups and proposed dividing Prevotella intermedia into 2 species, Prevotella intermedia and Prevotella nigrescens. This study was designed to examine the frequency of Prevotella intermedia and Prevotella nigrescens in diseased periodontal pockets and healthy gingival sulcus of Korean people by PCR based on 16s ribosomal DNA sequence. One hundred adults who had adult periodontitis but not taken any periodontal treatment or antibiotics during previous 6 months and 50 adults who had healthy periodontal tissue were selected for this study. The sulcular fluid was collected into VMGA by sterilized paper point and diluted to 1,000 times in anaerobic chamber. 100ml of sample was cultured in 37degrees C for 10 days. Among the bacterial colonies, BPB were selected and cultured in BHI broth and then Prevotella intermedia was identified through Gram staining and biochemical test. Identified Prevotella intermedia was cultured again and centrifuged. DNA was extracted from the pellet using several reagents. PCR was performed by previously designed primer. The results were followed. 1.BPB were isolated from 39 of 100 samples of diseased periodontal pockets(39%). 2.Prevotella intermedia was identified from 24 of 39 BPB samples. 3.Among 24 Prevotella intermedia, 21 were confirmed as Prevotella intermedia(87.5) and 2 were confirmed as Prevotella nigrescens(8.33%). 4.BPB were isolated from 9 of 50 samples of periodontally healthy patients. Among them only two were identified as Prevotella intermedia, that is, one was confirmed as Prevotella intermedia and the other was Prevotella nigrescens.

A horseshoe kidney is the most common renal fusion anomaly. It is well known that horseshoe kidneys may be associated with many urological problems, including calculi, vesicoureteral reflux, and ureteropelvic junction obstruction. However, a horseshoe kidney with unilateral severe hydronephrosis and ureteral hypoplasia is very rare. We report an 11-year-old female who underwent a retroperitoneoscopic nephrectomy for a horseshoe kidney with severe hydronephrosis and unilateral ureteral hypoplasia.

10.Is Oxytocin Application for Autism Spectrum Disorder Evidence-Based?.

Autism spectrum disorder (ASD) is characterized by persistent deficits within two core symptom domains: social communication and restricted, repetitive behaviors. Although numerous studies have reported psychopharmacological treatment outcomes for the core symptom domains of ASD, there are not enough studies on fundamental treatments based on the etiological pathology of ASD. Studies on candidate medications related to the pathogenesis of ASD, such as naltrexone and secretin, were conducted, but the results were inconclusive. Oxytocin has been identified as having an important role in maternal behavior and attachment, and it has been recognized as a key factor in the social developmental deficit seen in ASD. Genetic studies have also identified associations between ASD and the oxytocin pathway. As ASD has its onset in infancy, parents are willing to try even experimental or unapproved treatments in an effort to avoid missing the critical period for diagnosis and treatment, which can place their child in an irreversible state. While therapeutic application of oxytocin for ASD is in its early stages, we have concluded that oxytocin would be a promising therapeutic substance via a thorough literature review focusing on the following: the relationship between oxytocin and sociality; single nucleotide polymorphisms as a biological marker of ASD; and validity verification of oxytocin treatment in humans. We also reviewed materials related to the mechanism of oxytocin action that may support its potential application in treating ASD.
