PURPOSE: The purpose of this study was to compare knowledge level of those clinical nurses who received HPV vaccine and those who did not and their perception of the relatedness of HPV vaccine to causes of cervical cancer. METHODS: A total of 249 clinical nurses were surveyed from June to July, 2009. The questionnaire originally developed by Kim & Ahn (2007) examined HPV-related knowledge originally and the tool for perception of the causes of cervical cancer was originally developed by Kim (1993). The total number of subjects equaled to: vaccination group of 52 (20.9%) and non-vaccination group of 197 (79.1%). RESULTS: Vaccination group showed significantly higher score of both knowledge of HPV vaccination and the perception of the cause of cervical cancer in comparison to the nonvaccination group at (p<.05). Among 4 subscales of the perception of causes of cervical cancer, destiny and constitution subscale scores were significantly different between the two groups at (p<.05). CONCLUSION: Clinical nurses need to constantly update with current knowledge of HPV and be prepared with currently changing cancer prevention strategies, especially in cervical cancer.

Crypt glandular infection theory is accepted as an explanation of anal fistula's major cause. However, the pathogenesis of an anal fistula in Crohn's disease is different from that of a conventional anal fistula because a Crohn's anal fistula is caused by ulceration which, in turn, is caused by transmural inflammation of the rectal wall due to Crohn's disease. The difficulty with operating on anal fistulas in Crohn's disease lies in the fact that healing of the wound is inhibited because of continuous inflammation of the anorectal tissue due to Crohn's disease. Hence, there is a high possibility of incontinence due to sphincter muscle injury. Especially, because almost all Crohn's disease patients have frequent defecation and diarrhea, the patients will suffer more if incontinence occurs. Nowadays, even with increased understanding of the etiology of Crohn's disease, new medications, and aggressive surgical approaches, the result of treatment is still not satisfactory. Recently, since Korean eating habits have changed to include more western-style food in the diet, inflammatory bowel disease, such as Crohn's disease, is expected to increase. Consequently, the number of cases of anal fistulas in Crohn's disease is also expected to increase. The authors reviewed 20 confirmed cases of anal fistulas in Crohn's disease, which were treated from January 1993 to December 1995 at Song-Do Colorectal Hospital. The results are as follows: 1) Anal fistulas in Crohn's disease were present in 20(0.6%) of the 3378 cases of anal fistulas treated during the time period considered. 2) The male to female ratio for these 20 cases was 2: 1, and the most Prevalent age group was the 3rd decade, followed by the 2nd decade, the 4th decade, and the 5th decade in that order. 3) Three cases of anal fistulas whose origins could be explained by crypt glandular infection theory and which did not involve the rectum healed, although the healing was delayed. 4) Seventeen cases of anal fistulas whose origins could not be explained by crypt glandular infection theory and which involved the rectum did not heal after the operation. he results of the study show that anal fistulas whose origins can be explanined by crypt glandular infection theory and which do not involve the rectum can be cured by conventional fistula surgery. However, perirectal fistulas whose origins can not be explained by crypt glandular infection theory and which involve the rectum do not heal. Because there is the possibility of incontinence after a conventional operation, it is suggested that, in the cases of perirectal fistulas in Crohn's disease, better results, although not completely satisfactory, can be obtained by long-term seton drainage and diversion colostomy.

Antral web is a rare cause of gastric outlet obstruction in neonate. It is a 2-4 mm thin mucous membrane that can be found anywhere from 1 to 7 cm proximal to the pylorus. The baby was born at gestational age of 32(+1) weeks with 1,880 g as 2nd baby of dizygotic twin. After birth, the baby had constant non-bilious vomiting without feeding while he didn't show abdominal distension or discoloration. The infantogram showed distended stomach with distal small bowel gas. Upper gastrointestinal series revealed that the antrum was abruptly narrowed at 1 cm proximal to pylorus. We performed laparotomy at the 10th day after birth and excised the 2 mm-thick web circumferentially. He began milk feeding after 6 days and discharged uneventfully at postoperative 35 days with corrected age of 38(+4) weeks with body weight 2,420 g. The antral web should be considered in the case of non-bilious vomiting in neonate.

Accurate D antigen blood typing is needed owing to the clinical importance of the Rh blood group. We describe a female infant who was suspected to suffer from Rh incompatible hemolytic disease of the newborn, and who showed a strong positive direct antiglobin test (DAT) result and false red blood cell (RBC) agglutination in D typing. Using chloroquine dissociation of IgG, we confirmed that the antibodies coating her RBCs were of anti-D type. D typing with 0.8% RBC suspensions in saline using saline gel cards showed 2+ RBC agglutinations. After increasing the incubation time of dissociation by chloroquine for up to 4 hr, the dissociated RBCs began to show agglutination in both the tube technique (2+) and the gel card technique (4+) for D typing, although the DAT rest was still positive. Therefore, in order to prevent mistyping as a false-negative D blood group, whenever the D blood typing of a patient with a strong positive DAT rest does not show RBC agglutination, retesting of the D blood typing is recommended by using saline-suspended RBCs or dissociated RBCs.

Berardinelli lipodystrophy syndrome is a rare autosomal recessive disorder, characterized by loss of body fat, muscular hypertrophy, acanthosis nigricans, hepatomegaly, hyperlipidemia, insulin resistant diabetes, and elevated metabolic rate. The mechanism(s) responsible for these abnormalities is not known. We report a forteen-month old girl with Berardinelli Lipodystriphy Syndrome, who had signs above mentioned, with a brief review and its related literatures.

BACKGROUND: The VITROS 3600 (Ortho Clinical Diagnostics, Johnson & Johnson, Buckinghamshire, UK), which uses the enhanced chemiluminescence immunoassay, has recently been introduced; however, it has not been evaluated for detection of HBsAg in Korea. We evaluated the ability of the VITROS 3600 for detection of HBsAg, compared with the ARCHITECT i2000 (Abbott Laboratories, Abbott Park, IL, USA), which is used widely in Korea to help in selection of an analyzer for detection of HBsAg. METHODS: A total of 800 samples were tested randomly for HBsAg and 150 samples with positive HBV DNA detected by real-time PCR were used in this study. Precision, agreement, and Pearson correlations between two analyzers were evaluated. RESULTS: The total standard deviations (SD) were 0.016 and 0.183 for the negative and positive HBsAg controls, respectively; the precision met the criteria suggested by the manufacturer. There were 100% agreements for the 800 random samples (positive 33, negative 767) and 150 samples with HBV DNA (positive 148, negative 2) between two analyzers. In addition, good correlation was observed between two analyzers for the 767 HBsAg negative samples (r=0.691, P=0.004), and 148 HBV DNA positive samples (r=0.763, P<0.001). CONCLUSION: The VITROS 3600 showed good precision and agreement. And, correlation between the VITROS 3600 and the ARCHITECT i2000 was excellent. Therefore, this result will be helpful in selection of an analyzer for detection of HBsAg.

The aim of the present study was to examine the effect of provinol, which is a mixture of polyphenolic compounds from red wine, on the secretion of catecholamines (CA) from isolated perfused rat adrenal medulla, and to elucidate its mechanism of action. Provinol (0.3~3 microgram/ml) perfused into an adrenal vein for 90 min dose- and time-dependently inhibited the CA secretory responses evoked by ACh (5.32 mM), high K+ (a direct membrane-depolarizer, 56 mM), DMPP (a selective neuronal nicotinic NN receptor agonist, 100 micrometer) and McN-A-343 (a selective muscarinic M1 receptor agonist, 100 micrometer). Provinol itself did not affect basal CA secretion. Also, in the presence of provinol (1 microgram/ml), the secretory responses of CA evoked by Bay-K-8644 (a voltage-dependent L-type dihydropyridine Ca2+ channel activator, 10 microgram), cyclopiazonic acid (a cytoplasmic Ca2+-ATPase inhibitor, 10 microgram) and veratridine (an activator of voltage-dependent Na+ channels, 10 microgram) were significantly reduced. Interestingly, in the simultaneous presence of provinol (1 microgram/ml) plus L-NAME (a selective inhibitor of NO synthase, 30 micrometer), the CA secretory responses evoked by ACh, high K+, DMPP, McN-A-343, Bay-K-8644 and cyclpiazonic acid recovered to the considerable extent of the corresponding control secretion in comparison with the inhibition of provinol-treatment alone. Under the same condition, the level of NO released from adrenal medulla after the treatment of provinol (3 microgram/ml) was greatly elevated in comparison to its basal release. Taken together, these data demonstrate that provinol inhibits the CA secretory responses evoked by stimulation of cholinergic (both muscarinic and nicotinic) receptors as well as by direct membrane-depolarization from the perfused rat adrenal medulla. This inhibitory effect of provinol seems to be exerted by inhibiting the influx of both calcium and sodium into the rat adrenal medullary cells along with the blockade of Ca2+ release from the cytoplasmic calcium store at least partly through the increased NO production due to the activation of nitric oxide synthase.

Purpose: The aim of this descriptive study was to identify the factors influencing depression risk among South Korean nursing students. Methods: The data were collected from nursing students attending two universities through web-based questionnaires that surveyed them about depression, academic stress, social network service (SNS) addiction tendency, and upward social comparison from August 22 to September 4, 2021. The collected data from 196 nursing students were analyzed by t-test, one-way ANOVA, Pearson’s correlation coefficients, and multiple linear regression. Results: The mean score of depression (using CES-D Korean version) among nursing students was 13.91, which denotes probable depression. Concerning the variance with regard to depression among nursing students, 20.2% was explained by clinical practice period, academic stress, and upward social comparison. Conclusion Programs to relieve academic stress and depression should be developed in a simple way and systematically provided at the organizational level so that nursing students secure sufficient support during the initial and continuing period of clinical practicums. Concomitantly, an attempt to reduce the upward social comparison should be highly considered.

The metal chromium is widely used in industry. Hexavalent chromium is a strong oxidizing agent, and exposure to some hexavalent compounds can cause serious problems, such as skin ulcers, acute gastroenteritis, acute tubular necrosis with renal failure, and hepatic necrosis. We report a case of acute kidney injury following skin exposure to hexavalent chromium, which burned a relatively small percentage of the total body surface area (TBSA). A 49-year-old man developed oliguria and acute kidney injury 3 days after burning about 5% of his TBSA with chromic acid solution, causing second-to third-degree chemical burns. His creatinine level increased to 12.5 mg/dL. The patient underwent hemodialysis with supportive care. His renal function improved and the dialysis was discontinued. The serum and urine chromium concentrations also decreased.
