Objective: The features of childhood attention deficit hyperactivity disorder (ADHD) are significantly associated with adult mood disorders. Some genetic factors may be common to both ADHD and mood disorders underlie the association between these two phenotypes. The present study aimed to determine whether a genetic role may be played by the serotonin transporter-linked polymorphic region (5-HTTLPR) in the childhood ADHD features of adult patients with mood disorders. Methods: The present study included 232 patients with major depressive disorder (MDD), 154 patients with bipolar disorder (BPD), and 1,288 normal controls. Childhood ADHD features were assessed with the Korean version of the Wender Utah Rating Scale (WURS-K). The total score and the scores of three factors (impulsivity, inattention, and mood instability) from the WURS-K were analyzed to determine whether they were associated with the 5-HTTLPR genotype. Results: In the BPD type II group, the 5-HTTLPR genotype was significantly associated with the total score (p=0.029) and the impulsivity factor (p=0.004) on the WURS-K. However, the inattention and mood instability factors were not associated with the 5-HTTLPR genotype. BPD type I, MDD and normal control groups did not exhibit any significant associations between the WURS-K scores and the 5-HTTLPR genotype. Conclusion: The findings suggest that the 5-HTTLPR genotype may play a role in the impulsivity component of childhood ADHD in patients with BPD type II. Because of a small sample size and a single candidate gene, further studies investigating other candidate genes using a larger sample are warranted to determine any common genetic links.

Objective: We examined the relationship between chronotype and sleep disturbance, and assessed various factors that might be associated with sleep disturbance in Korean firefighters. Methods: Self-administered questionnaires assessing chronotype, depression, alcohol use, posttraumatic stress disorder (PTSD), stress response and sleep quality were examined in 515 firefighters. Results: Evening type firefighters more reported depression, alcohol use, PTSD, stress response and sleep disturbance. Also evening chronotype was the most significant risk factor for poor sleep quality (odds ratio [OR], 4.812; 95% confidence interval [CI], 2.448-9.459), even after controlling for all other variables (OR, 3.996; 95% CI, 1.806-8.841). Conclusion: Chronotype was the factor most strongly associated with sleep disturbance, and therefore should be considered an important variable in sleep quality, particularly in occupations involving stressful activities, such as firefighting.

Aspergillus tracheobronchitis (AT), an unusual form of invasive pulmonary aspergillosis (IPA), is characterized by pseudomem brane formation, ulcer or obstmction that is predominantly confined to tracheobronchial tree. Hematologic malignancies, neutropenia, solid organ transplantation, chronic corticosteroid therapy and acquired immunodeficiency syndrome (AIDS) are known to be major predisposing conditions. However, since the introduction of highly active antiretroviral therapy, there is only one reported case of AT in AIDS patient. After pandemic of influenza A/H1 N1 2009, there are several reports of I PA in patient with influenza and most of them received corticosteroid or immunosuppressive therapy before the development of I PA. We present a 45 year-old AIDS patient with influenza A infection who developed pseudomembranous AT without corticosteroid use or immunosuppressive therapy. [ABSTRACT FROM AUTHOR]

Background: Opportunistic infections are relatively rare in early human immunodeficiency virus infection, especially infection with Mycobacterium tuberculosis. Here, we report a patient who presented with acute human immunodeficiency virus and multidrug-resistant M. tuberculosis co-infections. Case presentation: A 27-year-old homosexual male was admitted for fever, cough, and hepatitis. At the time of admission, the p24 antigen was detected in his serum, indicating that he had an acute human immunodeficiency virus infection. He was also diagnosed with disseminated tuberculosis spreading to the lung and skin. Anti-tuberculosis medication had been started earlier with one-week intervals of highly active antiretroviral therapy. Despite prolonged anti-tuberculosis treatment, the patient developed tuberculous meningitis on the 50th day of admission. Multidrug-resistant tuberculosis was cultured from his sputum and cerebrospinal fluid. The patient was successfully treated with second line anti-tuberculosis medication and antiretroviral treatment. Conclusion: This is the first case of acute human immunodeficiency virus and multi drug-resistance tuberculosis co-infections. This case indicates that tuberculosis infection should be considered even in patients with acute human immunodeficiency virus infection. [ABSTRACT FROM AUTHOR]

Objective: The current study compared the long-term effectiveness, safety, and tolerability of paliperidone extendedrelease (ER) among patients with schizophrenia who had switched from risperidone (risperidone group) or other antipsychotic medications (non-risperidone group) due to lack of efficacy, intolerability, or nonadherence. Research design and methods: This open-label, prospective, multicenter, 48 week study utilized the Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impression–Severity scale (CGI-S), the Personal and Social Performance scale (PSP), and the Subjective Well-being under Neuroleptics scale (SWN) to assess patients with schizophrenia. Additionally, extrapyramidal symptoms (EPS) and subjective side effects were evaluated with validated scales. Results: The completion rate for this study was 51.6% (95/184), and 169 patients finished with ≥1 post-baseline assessment (81 patients in the risperidone group, 88 in the non-risperidone group). The mean (SD) PANSS total score decreased significantly from 78.3 (18.8) to 65.5 (19.7) in the risperidone group and from 79.1 (19.8) to 65.4 (20.8) in the other group (all p<0.001). Similar to PANSS, the severity rating for overall scores of the CGI-S and the PSP scores improved significantly from baseline (all p<0.001). The magnitude of improvement in all effectiveness measures at 48 weeks did not differ between the two groups. EPS and subjective side effects improved significantly for all patients. Akathisia (18.5%) and increased weight (14.1%) were the main adverse events. Elevated prolactin levels were identified in female subjects in the non-risperidone group. Conclusions: Switching from previously unsuccessful antipsychotic treatments to paliperidone ER can be a useful option to achieve long-term improvement in symptoms and functioning for patients with schizophrenia. The clinical effectiveness appeared to be similar in patients who previously received risperidone and those treated with other antipsychotic medications. The open-label design and lack of a placebo group were limitations. [ABSTRACT FROM AUTHOR]

As the number of Korean adults with diabetes is expected to increase continuously, the health care for these patients is becoming increasingly important. In recent years, the prevention of infectious diseases through vaccination of the adult population has attracted much interest. Patients with diabetes are more vulnerable to various infectious diseases and the prevention of these diseases through adequate vaccination is especially important. With the recent introduction of newly developed vaccines throughout the country, clinicians have more options for vaccinating their patients. In 2012, the Korean Society of Infectious Diseases developed revised guidelines for adult vaccination, which include recommendations for diabetic patients. Generally, vaccines for healthy adults are also recommended for diabetic patients, and these vaccines include those for Streptococcus pneumoniae, influenza, tetanus-diphtheria-pertussis, hepatitis A and B and herpes zoster. In this review, we will focus our discussion on the pneumococcal (PSV-13 and PPSV 23), influenza and zoster vaccines. [ABSTRACT FROM AUTHOR]

Objectives We investigated the tolerability, safety, and treatment response to flexible-dose paliperidone ER in patients with non-acute schizophrenia in whom previous antipsychotic drugs were ineffective. Methods This 24-week interim analysis of the 48-week multicenter, prospective, open-label study assessed effectiveness using the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Schizophrenia-Severity (CGI-SCH-S) Scale, Personal and Social Performance (PSP) and Drug Attitude Inventory (DAI). Safety and tolerability were assessed using the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) and Liverpool University Neuroleptic Side Effect Rating Scale (LUNSERS). Results Effectiveness was assessed in 169 patients. Significant improvement in the PANSS total score was observed by week-1 and continued until week-24. The response rate was 33%. The CGI-SCH-S and PSP total scores significantly improved during 24 weeks ; however, no change occurred in the total DAI. Fifty-nine percent of patients reported adverse events, of which extrapyramidal symptoms were the most frequent (19.0%). The DIEPSS and LUNSERS scores were improved after 24 week. Conclusions Switching to the flexible-dose paliperidone ER from an ineffective antipsychotic drug was safe, tolerable, and showed a good treatment response in Korean patients with schizophrenia [ABSTRACT FROM AUTHOR]

Objectives: Recent studies have reported a correlation between obstructive sleep apnea syndrome (OSA) and depression. In attempt to verify the suggestion that eveningness is related to depression, we examined the effect of morningness-eveningness on their depressive mood in patinets with OSA .Methods: The examination was based on the medical records and polysomnography reports of 211 OSA patients. Information was gathered from the patients who filled out the Hörne and Ostberg questionnaire (HOQ), profile of mood states-Korean version (K-POMS), and Epworth sleepiness scale (ESS). We compared mean values of K-POMS total, subscales of K-POMS, ESS, and OSA severity variables among the 3 morningness-eveningness groups (morningness, eveningness, and neither groups). Partial correlation analysis was performed between variables and ANCOVA was performed among the 3 groups after adjustment with age and weight.Results: There were significant negative correlations between HOQ and the followings : K-POMS total, POMS-T (tension-anxiety), POMS-D (depression-dejection), POMS-A (anger-hostility), POMS-F (fatigue-inertia), POMS-C (confusion-bewilderment), spontaneous arousal index, average O2 saturation. There were significant positive correlations between HOQ and the followings : POMS-V (vigor-activity), apnea-hypopnea index, respiratory arousal index, snore time. There were significant negative correlations between POMS-D and the followings : HOQ, POMS-V, stage 1 sleep (%), AHI, TAI (total arousal index), oxygen desaturation index, respiratory arousal index, neck circumference, average O2 desaturation, snore time (%). There were significant positive correlations between POMS-D and K-POMS total, POMS-T, POMS-A, POMS-F, POMS-C, sleep latency, stage 2 sleep (%), heart rate, spontaneous arousal index. There were significant differences in K-POMS total, POMS-T, POMS-D, POMS-F, POMS-C, spontaneous arousal index among the three HOQ groups in ANCOVA.Conclusion: The depressive correlates of OSA patients might be affected, not by excessive daytime sleepiness or OSA severity indexes, but by eveningness circadian characteristics. It would be important to take into account the morningness-eveningness tendency when we manage the depressive mood of OSA patients. [ABSTRACT FROM AUTHOR]

Objective: Morningness/eveningness (M/E) is a stable characteristic of individuals. Circadian rhythms are altered in episodes of mood disorder, Mood disorder patients were more evening-type than normal population. In this study, we compared the char-acteristics of M/E among the 257 patients with bipolar I disorder (BPD1), bipolar II disorder (BPD2) and major depressive disorder, recurrent (MDDR). Methods: M/E was evaluated using the Korean version of the composite scale of morningness (CS). Factor analysis was done to extract specific elements of circadian rhythm (morning preference, morning alertness, and evening tiredness). The total score and scores for factors and individual items of CS were compared in order to evaluate differences among the three different diagnostic groups. Factor scores of CS were different among the diagnostic groups. Results: BPD1 subjects had a higher score for evening tiredness than BPD2 subjects (,0=0.060), and BPD1 subjects had a sig-nificantly higher score for morning alertness than subjects with MDDR (p=0.034). This difference was even more profound for the representative item scores of each factor; item 2 of CS for evening tiredness (BPD1 >BPD2, p=0.007) and item 5 of CS for morning alertness (BPD1>MDDR, p=0.002). Total score of CS were not different among 3 diagnostic groups. Conclusion: Circadian rhythm characteristics measured by CS were different among BPD1, BPD2, and MDDR. BPD2 showed more eveningness than BPD1. MDDR showed less morningness than BPD1. CS would be a reasonable endophenotype associated with mood disorders. More studies with large sample size of mood disorders on M/E are warranted. [ABSTRACT FROM AUTHOR]

Melioidosis is a life-threatening disease caused by Burkholcleria pseudomallei, which is endemic in Southeast Asia and Northern Australia. It may manifest as a pulmonary lesion, osteomyelitis, septicemia, or abscesses of soft tissue or various organs. However, soft tissue abscess associated with bacteremia, especially those found in the head and neck, are rarely reported. We report a case of disseminated septicemia due to Burkholderia pseudomallei presenting as head and neck abscesses in a 55-year-old Korean man with a history of working in Malaysia. This is the first report of fatal melioidosis presenting as a complicated skin and soft tissue infection, in Korea. [ABSTRACT FROM AUTHOR]

The Diagnostic Interview for Genetic Studies (DIGS), developed in 1994 by the National Institute of Mental Health (NIMH), was translated into Korean and tested for reliability and diagnostic validity. Concurrent validity was tested using the Structured Clinical Interview for DSM-IV (SCID) and clinical diagnoses in 53 patients, most of whom had either schizophrenia or bipolar disorder. Inter-cater reliability was tested in 24 patients. Test-retest reliability was also tested in 17 patients. Overall and specific diagnostic validity for the Korean version of DIGS (DIGS-K) was excellent for most diagnoses. Inter-rater and test-retest reliability for overall and specific diagnoses also ranged from fair to excellent. For schizoaffective disorder, the test-retest reliability of DIGS-K was in a fair range, although the level was lower than that of other diagnoses. However, its diagnostic validity and inter-rater reliability was below fair range. In conclusion, DIGS-K appears to be a reliable interview for major psychiatric disorders. [ABSTRACT FROM AUTHOR]
