The glandular lesions of the uterine cervix can be classified into endocervical glandular dysplasia (EGD), adenocarcinoma in situ (AIS) and adenocarcinoma, but the diagnostic criteria and the continuity of endocervical glandular lesions are still controversial. The aim of this study was to evaluate the significance of immunohistochemical findings of p53 and MIB-1 in the discrimination and the continuity of EGD, AIS and adenocarcinoma. The materials for the study included 11 cases of adenocarcinoma, 7 cases of AIS, 12 cases of high grade EGD, and 19 cases of low grade EGD. Also included were eleven benign glandular lesions (5 cases of tuboendometrial metaplasia, 3 cases of mesonephric remnant, 3 cases of microglandular hyperplasia). A strong reaction of more than 5% of the glandular epithelial nuclei was interpreted as positive for p53 protein. MIB-1 expression was analyzed semiquantitatively as negative, 1 , 2 , 3 , depending on the percentage of positive nuclei (less than 1%, 1~9%, 10~39%, > or = 40%, respectively). p53 protein expression was found in 3 (27.3%) out of 11 cases of adenocarcinoma, and 2 (28.6%) out of 7 cases of AIS. But all of high and low grade EGD cases were negative. High MIB-1 labelling index (> or =10%) was found in all adenocarcinoma cases and in 3 (42.9%) out of 7 cases of AIS. But only 2 (17.7%) out of 12 cases of high grade EGD showed high MIB-1 labelling index, and all of low grade EGD and benign lesions showed negligible MIB-1 positivities. In summary, MIB-1 labelling index might be valuable in the discrimination of malignant glandular lesions and endocervical glandular dysplasia from benign lesions, but p53 expression could be a useful parameter in the discrimination of malignant glandular lesions from endocervical glandular dysplasia and benign lesions.

Bromidrosis is a disorder characterized by rancid body odor which influences a patient's social life and mental health. The therapeutic modalities and the mechanism of bromidrosis have been carefully studied, however, there have been few reports about the genetic inheritance of bromidrosis. We investigated the family history of 42 patients who were operated on for bromidrosis and followed up to the third generation in 10 cases. The results were as follows: Results of investigation which were followed up the second generation. The fathers of five patients and the mothers of 11 patients had bromidrosis in 18 male patients. The fathers of six patients and the mothers of 12 patients had bromidrosis in 24 female patients. Thirty-four patient (81.0%) among a total of 42 have a single parent with bromidrosis. Result of investigation which were followed up to the third generation Bromidrosis was occurred in 17 of 42 patients (40.5%) in the second generation, and 18 of 27 patients (66.7%) in the third generation. In one case, a father transmitted bromidrosis to his three sons, and as a result, X-linked inheritance could be ruled out Bromidrosis was not skipped in every generation of all families. We on conclude that bromidrosis is an autosomal dominant inherited disorder.

BACKGROUND: We aimed to establish robust histoprognostic predictors on residual rectal cancer after preoperative chemoradiotherapy (CRT).METHODS: Analyzing known histoprognostic factors in 146 patients with residual disease allows associations with patient outcome to be evaluated.RESULTS: The median follow-up time was 77.8 months, during which 59 patients (40.4%) experienced recurrence and 41 (28.1%) died of rectal cancer. On univariate analysis, residual tumor size, ypT category, ypN category, ypTNM stage, downstage, tumor regression grade, lymphatic invasion, perineural invasion, venous invasion, and circumferential resection margin (CRM) were significantly associated with recurrence free survival (RFS) or/and cancer-specific survival (CSS) (all p<0.005). On multivariate analysis, higher ypTNM stage and CRM positivity were identified as independent prognostic factors for RFS (ypTNM stage, p=0.024; CRM positivity, p<0.001) and CSS (p=0.022, p=0.017, respectively). Furthermore, CRM positivity was an independent predictor of reduced RFS and CSS, irrespective of subgrouping according to downstage (non-downstage, p<0.001 and p<0.001; downstage, p=0.002 and p=0.002) or lymph node metastasis (non-metastasis, p<0.001 and p=0.001; metastasis, p<0.001 and p<0.001).CONCLUSION: CRM status may be as powerful as ypTNM stage as a prognostic indicator for patient outcome in patients with residual rectal cancer after preoperative CRT.

BACKGROUND: The transrectal ultrasound-guided prostate biopsy (TRUS-PBx) is one of the most common procedures among day care center based urologic procedures. Our aim was to determine if pretreatment with meperidine could improve the quality of anesthesia in patients undergoing deep sedation for TRUS-PBx. METHODS: Sixty male patients (30–80 years; American Society of Anesthesiologists physical status class I or II) scheduled for TRUS-PBx were allocated randomly into two groups. After pretreatment with normal saline (Group C) or intravenous (i.v.) meperidine 0.5 mg/kg (Group M), sedation was induced with i.v. propofol 1.5 mg/kg. Additional doses of i.v. propofol 0.5 mg/kg were administered upon patient movement. During the procedure, hemodynamic variables, patient movement, and the bispectral index were measured. After the procedure, the mean modified observer's assessment of alertness/sedation score (MOASS), postprocedural pain, side effects, and patient satisfaction were evaluated. RESULTS: During the procedure, patient movement was not significantly different between the two groups, but Group M required a significantly lower total propofol dose compared to that of Group C (P = 0.036). After the procedure, the MOASS was comparable between the two groups (P = 0.055), but Group M patients experienced significantly less postprocedural pain (P = 0.012), lower systolic and diastolic blood pressure at 45 (P = 0.044 and P = 0.014) and 60 minutes (P < 0.001 and P = 0.006), and lower incidence of tenesmus than Group C (P = 0.020). CONCLUSIONS: Meperidine can be used as a safe, effective analgesic with deep sedation for patients undergoing TRUS-PBx.

Phenylketonuria (PKU), an autosomal recessive disorder, occurs in one of 53,000 births in Korea. The disorder is associated with deficient activity of phenylalanine hydroxylase. In PKU, phenylalanine cannot be used in a normal fashion because of the deficient enzyme. Untreated, affected individuals develop marked mental disabilities, behavioral difficulties, seizures, rashes, pigment dilution, and unusual body odor. PKU treatment consists of a phenylalanine-restricted diet supplemented with a phenylalanine-free mixture of amino acids. During the restricted diet, PKU patients have an increased risk of developing vitamin B12 deficiency because of a limited intake of animal products. We report a successful anesthetic management in a patient with phenylketonuria for dental procedures.

BACKGROUND: The delta neutrophil index (DNI) is a useful marker for diagnosing and predicting the prognosis of sepsis. The purpose of this study was to investigate the usefulness of DNI as a prognostic marker in patients within the pediatric intensive care unit (PICU), as well as its association with other prognostic factors. METHODS: A total of 516 children admitted to Severance Children's Hospital PICU from December 2009 to February 2015 were analyzed. DNI was measured on the day of PICU admission. Mortality was defined as death within 28 days following PICU admission. RESULTS: The median value of DNI was 1.2% (interquartile range [IQR] 0-4.3%) in the survivor group and 9.5% (IQR 2.3-20.8%) in the non-survivor group, and the difference was statistically significant (p < 0.001). DNI was significantly positively correlated with ICU scores such as Pediatric Index of Mortality 3 and Pediatric Risk of Mortality III, as well as with C-reactive protein and lactate levels. The area under the receiver operating characteristic curve of DNI for mortality was 0.748 (95% CI: 0.687-0.808) and the cut-off value was 4.95%. CONCLUSIONS: The initial DNI level can be considered a useful indicator for predicting prognosis in PICU patients.

Postconditioning has been shown to protect the mouse brain from ischemic injury. However, the neuroprotective mechanisms of postconditioning remain elusive. We have found that toll-like receptor 5 (TLR5) plays an integral role in postconditioning-induced neuroprotection through Akt/nuclear factor kappa B (NF-κB) activation in cerebral ischemia. Compared to animals that received 30 min of transient middle cerebral artery occlusion (tMCAO) group, animals that also underwent postconditioning showed a significant reduction of up to 60.51% in infarct volume. Postconditioning increased phospho-Akt (p-Akt) levels and NF-κB translocation to the nucleus as early as 1 h after tMCAO and oxygen-glucose deprivation. Furthermore, inhibition of Akt by Akt inhibitor IV decreased NF-κB promoter activity after postconditioning. Immunoprecipitation showed that interactions between TLR5, MyD88, and p-Akt were increased from postconditioning both in vivo and in vitro. Similar to postconditioning, flagellin, an agonist of TLR5, increased NF-κB nuclear translocation and Akt phosphorylation. Our results suggest that postconditioning has neuroprotective effects by activating NF-κB and Akt survival pathways via TLR5 after cerebral ischemia. Additionally, the TLR5 agonist flagellin can simulate the neuroprotective mechanism of postconditioning in cerebral ischemia.

Clay-shoveler’s fractures are rare stress-type avulsion fractures of the spinous processes especially in sports. There have been two case reports that discussed clay-shoveler’s fractures in golf. A 36-year-old beginner golfer presented with a pain in the back after practicing golf swing. No fractures were detected using cervical radiography; however, computed tomography (CT) and magnetic resonance imaging (MRI) revealed T2∼T3 spinous process fractures. The patient was treated conservatively and his pain subsided. The mechanism of injury is speculated to that of clay-shoveler’s fractures. Therefore, if a golfer suffers persistent pain in the cervicothoracic region, clay-shoveler’s fracture is one possibility to consider.
