PURPOSE: The purpose of this study is to test a model linking infant health problem, mother's depression and marital relationship to infant abuse. METHODS: This study employed a cross-sectional survey design. Data were collected from 2009 Data of Index Studies for Korean Children and Adolescents Development. Survey data from 1,060 infants and their mothers (including infant health status and infant physical illness scale, depression scale, marital relationship scale, and child abuse scale) were used to test the model. The model was tested using path analysis techniques within structural equation modeling. RESULTS: The model fit indices suggested that the original hypothesized model adequately fit the data (chi2 = .33, df = 5, p = .84, Tucker-Lewis Index = 1.04, Comparative Fit Index = 1.00, Root Mean Square Error of Approximation = .00). Infant health problem and mother's depression had a negative direct effect on marital relationship, which in turn had a direct negative effect on infant abuse. Infant health problems directly affected infant abuse and also influenced infant abuse indirectly through the marital relationship. Mother's depression had significant direct effects on infant abuse and also influenced infant abuse indirectly through the marital relationship. CONCLUSION: The findings from this study demonstrate the fundamental importance of infant health as linked to the mother's mental health, and marital relationship and increasing the quality of marital relationship may be the key to infant abuse prevention.

During temporomandibular joint (TMJ) formation, discomalleolar ligament (DML) and anterior malleolar ligament (AML) are formed within the dorsal end of the 1st branchial arch. But, DML is known as a remnant or the degenerated tissue through the TMJ development. There is few reports said that damage of AML and DML cause the damage of middle ear during surgical procedures. Especially, in case of anterior disk displacement of TMJ, aural symptom can be made via DML due to hyperextension anteriorly. A few studies have been reported about DML and AML in embryological and histological points of view, morphology and clinical aspects of DML and AML are still unclear. Four fetuses and sixteen adult hemi -sectioned heads were dissected to clarify the topographical relationship of AML and DML and to find out the anatomico -clinical relevance related with temporomandibular disorder. In fetal specimens, DML was firmly attached from the disk of the TMJ to the malleus. Also, AML in which distinguished into the superior and inferior lamellae was running anteriorly and continuous with the sphenomandibular ligament (SML) through the future petrotympanic fissure (PTF). DML attached to the malleus was observed in all adult specimens and was expanded broadly to the disk and capsule of the TMJ as shown the V -shaped ligament structures. The average distance between the anterior aspects of the malleolar head to the anterior wall of the tympanic cavity was 1.13 mm(0.75 ~1.59), and the length of the DML from the anterior aspect of the malleolar head to the attached site to the TMJ capsule at the PTF was 5.37 mm (4.53 ~6.07). The average width of the DML at the PTF was 6.06 mm (4.72 ~7.46). Most of the posterior attachments of the DML were the cases in which DML was directly attached to the malleus (68.7%). In all specimens, DML was attached to the disk and capsule of TMJ and attached to the anteromedial border of the PTF concurrently. In this study, two morphological patterns of AML were observed according to the presence of the bony ridge on the Huguiers canal in the PTF. The bony ridge of the Huguiers canal showed DML and AML separately in 56.3%, and the fused pattern of DML and AML was observed in 43.7%. AML was not distinguished with two lamellae in most specimens, superior ligament fibers were attached to the anteromedial border of the PTF and most of the inferior lamella was entering the gap in PTF and continuous with the SML. Average length from the anterior aspect of the malleolar head to the exit point of the AML on the PTF was 8.40 mm(6.62 ~11.42), and the shortest distance between the AML and chorda tympani was 2.01 mm(1.25 ~3.02). Taken all together, DML and AML were not the rudimentary, but the distinguishable structures in adults. Through the various morphological findings, DML and AML were separated ligamentous structures in which might be given rise from the divergent origin. And the anterior hyperextension of the disk of TMJ did not lead the movement of the malleus in the tympanic cavity, whereas, the movement of the malleus followed by the traction of the AML and SML was observed in a few cases. So, this results can be explained the possibility of the clinical symptom on the middle ear in case of the over -traction of the AML and SML.

PURPOSE: In May 2008, a diarrhea outbreak occurred among students of in a girls' high school (S school) in Sangju-si, Korea. An epidemiological investigation was carried out to clarify the cause and transmission route of the outbreak. METHODS: S school has been providing meals directly since July 2007. We conducted a questionnaire survey among 591 persons, and examined 283 rectal swabs and 98 environmental specimens. The patient case was defined as a member of S school who had diarrhea more than one time in a day, accompanied with one or more symptoms among abdominal pain or tenesmus from May 19th to May 26th 2008. RESULTS: The attack rate was 24.0%. Bacillus cereus were cultured from three of the rectal swabs and five of the preserved foods. It was suspicious that contamination was possible in seasoning vegetables, and we found some foods were seasoned with spices after being cooled by moving cooler for about 20 minutes. Enterotoxin positive B. cereus were cultured from two foods cooled by moving cooler. Enterotoxin negative B. cereus were cultured from two environmental specimens of the moving cooler. CONCLUSIONS: We presumed the cause of the diarrhea outbreak in S school was food poisoning by B. cereus. Because enterotoxin positive B. cereus were cultured from rectal swabs and foods, and the symptoms were corresponded. We estimated the outbreak was occurred by this process that B. cereus in the moving cooler contaminated foods during cooling and then rapidly proliferated.

OBJECTIVES: It was aimed to observe the regional cerebral blood flow (rCBF) response on methamphetamine challenge test in rats which were subjected to repeated administration of methamphetamine, and to investigate the mechanism(s) of changes in rCBF response in relation to the dopaminergic receptors and cyclic AMP. METHODS: Male Sprague-Dawley rats received daily injections of methamphetamine (0.3 mg/kg, i.p.) for 10 days, and were then allowed a 4-day drug-free period. Naive and methamphetamine-pretreated rats were challenged with topical application of methamphetamine on the surface of parietal cortex through a cranial window. The changes in rCBF were measured by laser-Doppler flowmetry. RESULTS: Acute topical application of methamphetamine dose-dependently increased rCBF with little effect on mean arterial blood pressure. The methamphetamine-induced increases in rCBF were significantly blocked by SCH23390, a D1-like receptor antagonist, but not by sulpiride, a D2-like receptor antagonist. Repeated administration of methamphetamine induced progressive augmentation of rCBF in response to the challenge of methamphetamine. Repeated administration of methamphetamine in combination with SKF38393, a D1-like receptor agonist, as well as with SCH23390 significantly attenuated the development of augmentation of rCBF response to methamphetamine. The augmentation of rCBF response was markedly inhibited by pretreatment with 2',3'-dideoxyadenosine, a specific adenylyl cyclase inhibitor, and Rp-cAMPS, a protein kinase A inhibitor, respectively. CONCLUSION: Based on these results, it is suggested that repeated administration of methamphetamine induces an augmentation of rCBF in response to the challenge of methamphetamine, and that D1-like receptor-mediated cyclic AMP plays a critical role in the development of augmentation of methamphetamine-induced rCBF response.

Labial adhesions are extremely rare in adolescent and adult populations, because the etiology of this entity commonly relates to chronic vulvar inflammation or irritation, and is basically associated with low estrogen status. Although a few cases reported urinary retention resulting from severe labial adhesions, there is no report of labial adhesion that precipitates upper genital tract infection in prepubertal and postpubertal females. We present a rare case of severe labial adhesion and consequential lower genital tract obstruction that allegedly causing bilateral pyosalpinx in a 14-year-old adolescent girl who decisively denied sexual experience. The patient was successfully treated with surgical lysis of adhesion and administration of antibiotics.

Variant angina pectoris is characterized by chest symptoms at rest and transient ST elevation on the electrocardiography due to coronary artery spasm. Although most patients with coronary spasm respond well to medical treatment with vasodilators such as calcium channel blockers and nitrates, some patients show intractable attack of coronary vasospasm despite standard medical therapy. We experienced 50-year-old woman with intractable chest pain due to coronary artery spasm, who suffered from ventricular fibrillation despite continuous intravenous nitrate therapy.

OBJECTIVES: Despite the importance of human immunodefi-ciency virus(HIV) transmission through heterosexual contact, the features of heterosexual transmission has not been well studied in Korea. So we conducted a cross sectional study to determine the transmission rates in married couples and assess risk factors for male to female heterosexual transmission of HIV. METHODS: 169 HIV-infected males and their female sex partners were recruited from 1985 to June 1998. We examined female sex partners HIV infection status and interviewed male index partners and their female sex partners about demographic characteristics and sexual practices. We analysed heterosexual transmission rate by epidemiologic characteristics, disease status and sexual practices. And we assessed risk factors for HIV infection by univariate and multivariate analysis. RESULTS: 30 female sex partners were infected at enrollment, yielding an transmission rate of 17.8%. Among couples who had used condoms consistently, none of the female sex partners was infected with HIV. In univariate analysis the significant risk factors were full blown AIDS status (OR=4.1, 95% CI: 1.49-11.43) and low CD4 T cell count of index partners at enrollment (OR=7.8, 95% CI: 2.19-27.80). In multivariate analysis HIV-1 RNA levels was significant risk factor when adjusted by CD4 T cell counts and mean sexual contacts per month (OR=19.2, 95% CI: 1.03-357.59) CONCLUSION: The risk of male to female heterosexual transmission increased with advanced stages of HIV infection in the index male partners.
