Background: This study aimed to investigate the reliability and validity of the Chinese version of the Patient Health Questionnaire (PHQ-15) in a tertiary hospital. Methods: Using a cross-sectional study design, the Chinese version of the PHQ-15 was administered to a total of 1329 inpatients. To examine the discriminant validity of this questionnaire, we investigated the correlation of the PHQ-15 score with sociodemographic data and the PHQ-9 and GAD-7 scale scores. Exploratory factor analysis was performed to assess the internal consistency of the PHQ-15. To evaluate the consistency of this questionnaire with item response theory (IRT), IRT analysis was performed.

Conclusions: The PHQ-15 scale had good reliability and high validity to detect patients with high somatic symptom severity in a Chinese tertiary hospital. Several of the current findings were consistent with previous research on the PHQ-15 in Western countries and in China. To improve the diagnostic quality of this questionnaire, items 4, 8 and 11 can be omitted. [ABSTRACT FROM AUTHOR]

This study characterized particulate matter 2.5 microns in the naturally ventilated Pediatric and Medicine wards and mechanically ventilated Central and Neonatal Intensive Care Units (CENICU and NICU) of an urban tertiary care hospital in the Philippines in terms of concentration, elemental composition, indoor/outdoor (I/O) ratios and enrichment factors. The samples were collected from October to December 2013 and from March to April 2014. Results showed that the average of PM 2.5 in the Pediatric (32.8 μgm -3 in October to December 2013 and 28.4 μgm -3 in March to April 2014) and Medicine Wards (30.0 μgm -3 in October to December 2013) exceeded the WHO guideline value of 25 μgm -3 . The I/O ratios suggest that outdoor air is the major source of PM 2.5 in all sites. Comparison of pollutant levels showed differences between the PM 2.5 concentrations in Pediatrics and NICU (p < 0.0001 in October to December 2013 and p = 0.003 in March to April 2014) and in Medicine and CENICU (p = 0.002 in October to December 2013 and p = 0.037 in March to April 2014). Moreover, outdoor PM 2.5 concentrations were higher than the measurements in NICU and CENICU (p < 0.0001). X-ray fluorescence analysis measured 15 elements, including manganese, iron, vanadium, lead and mercury, which are highly hazardous to health. Enrichment factor analysis showed that mercury, sulfur and bromine were highly enriched indicating significant contamination from anthropogenic sources. The researchers recommend the determination of these elements in soil within the area and other compartments and undertake a source apportionment study to ascertain the sources of these elements.

Background: Skin diseases affect 21-87 % of children in developing countries in Africa. However, the spectrum of the skin diseases varies from region to region due to several factors such as genetics, socioeconomic and environmental. The aim of this study was to determine the spectrum of childhood skin diseases in Tanzania.Methods: We conducted a prospective hospital- based cross-sectional study between September 2012 and August 2013 at a tertiary referral dermatology clinic. Children younger than 14 years presenting with new skin conditions were recruited. Diagnosis was mainly done clinically, but if the diagnosis was not clinically clear, further investigations were undertaken accordingly.Results: A total of 340 patients were recruited of which 56 (16.5 %) had more than one skin condition. Both genders were equally affected. Infections and infestations accounted for the majority (43.5 %, n = 177) of the skin conditions followed by eczematous dermatitis (28.5 %, n = 116) and pigmentary disorders (7.4 %, n = 30). Among the 152 infectious skin diseases, fungal infections predominated (50.7 %, n = 77) in the infectious group followed by bacterial (29.6 %, n = 45), and viral (19.7 %, n = 30).Conclusions: Skin infections are still the main cause of dermatological consultations in children although with a reduced prevalence. Inflammatory skin conditions are increasing and can be attributed to improved socioeconomic status and HIV pandemic. [ABSTRACT FROM AUTHOR]

Background: HIV/AIDS and Diabetes Mellitus are the diseases’ known to supress cell mediated immunity and predispose patients for opportunistic infections. Hence, we conducted a study to compare the common opportunistic infections (OIs) between People Living with HIV with DM (PLHIV-DM) and PLHIV without DM (PLHIV). Methodology: PLHIV with DM and without DM (1:1) were prospectively included in the study from January 2011 to January 2012 at a tertiary care hospital in Mangalore city. Patients were classified as Diabetic if their fasting plasma glucose was ≥ 7.0mmol/l (126mg/dl) or 2–h plasma glucose was ≥11.1mmol/l (200mg/dl). Standard procedures and techniques were followed for diagnosis of OIs as per WHO guidelines. The data was entered and analyzed using Statistical Package for Social Sciences (SPSS) version 11.5. Findings: The study included 37 PLHIV with DM and 37 PLHIV without DM and both groups were treated with Anti-Retroviral Therapy (ART). The median age was 47 years (IQR: 41-55years) for PLHIV-DM as compared to 40 years (IQR: 35–45.5 years) for PLHIV (p<0.0001). PLHIV-DM had median CD4 counts of 245 (IQR: 148–348) cells/μl compared to 150(IQR: 70–278) cells/μl for PLHIV (p = 0.02). Common OIs included oral candidiasis (49% of PLHIV-DM and 35% of PLHIV); Cryptococcal meningitis (19% of PLHIV-DM and 16% of PLHIV); Pneumocystis jiroveci pneumonia (5% of PLHIV-DM and 18% of PLHIV); extra pulmonary tuberculosis (22% of PLHIV-DM and 34.5% of PLHIV); and Cerebral toxoplasmosis (11% of PLHIV–DM and 13.5% of PLHIV). Microbiological testing of samples from PLHIV- DM, C krusei was the most common Candida species isolated from 9 out of 18 samples. Out of six pulmonary TB samples cultured, four grew Non-tuberculosis mycobacteria (NTM) and two Mycobacterium tuberculosis complexes. Conclusions: Study did not identify any significant difference in profile of opportunistic infections (OIs) between PLHIV with and without Diabetes. [ABSTRACT FROM AUTHOR]

Objectives: Staphylococcus lugdunensis can cause community- and healthcare-associated infections. This study investigated the molecular characteristics of S. lugdunensis isolates collected at our hospital and compared the characteristics of the infectious and commensal isolates. Methods: We collected the S. lugdunensis isolates between 2003 and 2013. The antimicrobial resistance test, SCCmec typing, accessory gene regulator (agr) typing, pulsed-field gel electrophoresis (PFGE), and δ-like hemolysin activity were performed. Results: In total, 118 S. lugdunensis isolates were collected, of which 67 (56.8%) were classified into the infection group and 51 (43.2%) into the commensal group. The oxacillin resistance rate was 36.4%. The most common SCCmec types were SCCmec types V (51.4%) and II (32.6%). In total, 34 pulsotypes were identified. The PFGE typing revealed five clones (pulsotypes A, J, M, N, and P) at our hospital. Pulsotypes A and N caused the spread of high oxacillin resistance. In total, 10.2% (12 of 118) of the isolates lacked δ-like hemolysin activity. Compared with the infection group, the commensal group showed a higher percentage of multiple drug resistance and carried a higher percentage of SCCmec type II (11 of 22, 50% and 3 of 21, 14.3%) and a lower percentage of SCCmec type V (8 of 22, 36.4% and 14 of 21, 66.7%). The commensal group (27 PFGE types) showed higher genetic diversity than did the infection group (20 PFGE types). No difference was observed in the distribution of the five main pulsotypes, agr typing, and the presence of δ-like hemolysin activity between the two groups. Conclusions: Five main clones were identified at our hospital. The commensal group showed higher genetic diversity, had a higher percentage of multidrug resistance, and carried a higher percentage of SCCmec type II and a lower percentage of SCCmec type V than did the infection group.

Introduction: Staphylococcus aureus is one of the most common pyogenic bacteria. They are notorious for developing prompt resistance to newer antimicrobials. With increasing incidence of methicillin-resistant S. aureus (MRSA) isolates, the treatment options are also becoming limited. Clindamycin is an excellent drug for skin and soft tissue infections, but resistance mediated by the inducible phenotype (iMLSB) leads to in vivo therapeutic failure even though there may be in vitro susceptibility. The double disk approximation test (D-test) can reliably detect the presence of such isolates. This study was aimed to detect and report the prevalence of the iMLSB phenotype in NEIGRIHMS, a tertiary care center in Northeast India. Methodology: A total of 243 consecutive isolates were subjected to routine identification tests followed by antimicrobial sensitivity testing. Erythromycin-resistant isolates were tested for inducible resistance phenotype by the D-test. Results: Among strains tested, 95 (39%) were erythromycin resistant. Twenty-six (10.7%) isolates were D-test positive (iMLSB phenotype), 41 (16.88%) were constitutively resistant (cMLSB phenotype), and 28 isolates (11.52%) were found to be negative by D-test. The incidence of both inducible and constitutive phenotypes was higher in MRSA isolates compared to methicillin-sensitive S. aureus (MSSA) isolates. Conclusions: This study revealed a moderate prevalence of the inducible clindamycin phenotype in the staphylococcal isolates tested. Clinical microbiology laboratories in areas of high MRSA prevalence should consider performing the D-test routinely. This will help prevent prescription of drug(s) whose therapeutic efficacy is doubtful. [ABSTRACT FROM AUTHOR]

Objective(s) Dyspnoea is a common and often debilitating symptom that affects up to 50% of patients admitted to acute tertiary care hospitals. The primary purpose of this study was to compare the numeric rating scale (NRS) and the visual analogue scale (VAS) for dyspnoea evaluation in the ED setting. Study design and patients This was a cohort study of patients admitted to the ED in a university hospital, with dyspnoea as the chief complaint. Methods The agreement of the two dyspnoea scales was assessed using the intraclass correlation coefficient (ICC). Results One hundred and seventeen patients were included in this analysis. The median age for the whole study population was 67 years and 42% of patients were male. The aetiology of dyspnoea was acute heart failure (AHF) in 35% of patients. There was good agreement between the two scores (ICC = 0.795; 95% CI = 0.717–0.853; P < 0.001). Conclusions This pilot study demonstrated that numerical rating and visual analogue scales agree well when assessing the severity of dyspnoea in the ED. Further studies with larger cohorts of patients are needed to confirm these preliminary results. [ABSTRACT FROM AUTHOR]

Some cases of psoriatic arthritis (PsA) cannot be explicitly diagnosed, especially when the skin and nail lesions present years after the joint disease or are absent. Autoimmunity may also play a role in the development of Dupuytren's disease. However, the simultaneous presence of PsA and Dupuytren's disease is very rare. We present a patient displaying arthritis in multiple small joints, with bone erosions and bony fusions in all four extremities, combined with Dupuytren's disease. Because of the atypical clinical manifestation, the diagnosis perplexed doctors for decades. Without formal treatment, the disease followed a natural course over time. Reviewing the patient's data, a potential diagnosis of PsA, combined with Dupuytren's disease, was eventually made. After surgery, contractures of palmar and plantar fascia as well the thumb web were released, and the hallux valgus was corrected. [ABSTRACT FROM AUTHOR]

Objective: To discuss the medical, social and legal characteristics of the child sexual abuse and to provide a perspective for gynecologists on this topic. Methods: A retrospective analysis was carried out of the medicolegal records of female children below the age of 18 referred to a tertiary teaching hospital and diagnosed as being exposed to sexual abuse within the family between the years of 2004 to 2012. Results: One hundred and thirty-nine cases were diagnosed as being exposed to sexual abuse during the 8 year period, 23 of them (16.5%) had been involved in sexual abuse within the family. Eleven out of 23 had been admitted as part of a legal process while the rest were reported by a third person. Conclusion: Since sexual abuse within the family is a taboo in Islamic societies, the diagnosis can take a long time. Recognition of sexually abused children, providing early performance of medicolegal examinations, and applying standardized medical guidelines are essential to protect these children.

Objective: To determine the frequency of etiological factors in short statured patients presenting at endocrine clinic of National Institute of Child Health, Karachi. Methods: This descriptive cross sectional study was conducted at Endocrine clinic of National Institute of Child Health, Karachi. One hundred children (48 boys and 52 girls) aged 3-15 years (mean 9.9±3.4) with short stature from January 2007 to July 2007 were evaluated during that period. Results: Constitutional growth delay (CGD) and familial short stature (FSS) were identified as the most common, 55% of all short stature cases. Non-endocrinal causes as a single entity was detected in 17 children. Most common etiological factors in order of frequency were normal variant of growth (CGD, FSS), Hypothyroidism, Growth Hormone deficiency (GHD), and Celiac disease. GHD was found in 13% of total cases and it comprises 44% among endocrinal causes. Boys outnumbered girls with ratio of 2.7:1 (p < 0.05). Conclusion: Most common cause of short stature was normal variants of growth as a group. Children with height falling below 0.4th percentile are more likely to have pathological cause.

Background and Objectives: Methicillin-resistant S. aureus (MRSA) tends to be resistant to multiple antibiotics. Methicillin resistance is conferred by the acquisition of the mecA gene, which is carried by a mobile genetic element called the staphylococcal cassette chromosome mec (SCCmec). There are five major types of SCCmec elements (I-V). The majority of hospital-acquired MRSA (HA-MRSA) strains carry SCCmec types I, II, or III, whereas community-acquired MRSA (CA-MRSA) strains carry SCCmec types IV or V. In addition, Panton-Valentine Leucocidin (PVL) is a gene encoding a powerful cytotoxin that is strongly associated with CA-MRSA strains. The present study was aimed to identify the types of SCCmec and PVL genes among clinical MRSA isolates. Methods: This study was conducted in 5 tertiary care hospitals in Makkah city from March to September of 2012. A total of 206 S. aureus clinical isolates were analysed using standard microbiological methods. Multiplex PCR was performed on genomic DNA from MRSA isolates in order to identify the types of SCCmec. In addition, PCR was performed to detect the PVL gene among the isolates. Results: Of the 206 S. aureus isolates, 114 (55.3%) were MRSA, and 100 of the MRSA isolates carried the mecA gene. Results from SCCmec typing revealed that 3% were type I; 9% were type II; 47% were type III, and 29% were type IV. Nineteen per cent of the isolates harboured the PVL gene. Furthermore, there was a statistically significant correlation between the presence of the PVL gene and SCCmec type IV. Conclusion: The virulence of MRSA strains is increasing in both hospital and community settings in Makkah, highlighting the importance of their rapid identification in order to appropriately control infection.

Background: Liver disease is frequently missed as the cause for a patient's thrombocytopenia. Aim: To evaluate the role of liver disease in causing thrombocytopenia within a tertiary hospital. Design: A hospital-based retrospective study. Methods: Analysis of medical records of outpatients and inpatients with a platelet count <100×109/l seen at St Mary's Hospital, London in October 2011, was conducted. Cause for thrombocytopenia was determined in each case and patients with liver disease were analysed further looking at factors associated with their low platelet count. Results: In total, 223 patients were included in this study, 109 of them were outpatients and 114 were inpatients. The mean age was 57.1 years (range 22-106), 64% male and 36% female. Liver disease was the cause for thrombocytopenia in 58% of outpatients. Overall, 92 patients with liver disease were identified; cirrhosis and/or splenomegaly were present in 78%, a further 8% were on interferon therapy. Thrombocytopenia was not explained by the extent of liver disease in 8%, significantly more in hepatitis C than other causes of liver disease (P < 0.05). Factors correlating with low platelet count in patients with liver disease were spleen size (P < 0.05) and serum bilirubin (P < 0.001). There were none, or mild abnormalities only in liver function tests in 19 patients with liver disease-associated thrombocytopenia. Conclusions: Liver disease should be considered in all patients with an unknown cause of thrombocytopenia. Advanced liver disease does not have to be present for thrombocytopenia to develop. All patients with unexplained thrombocytopenia should be evaluated to see if liver disease is present, even when liver function tests are normal. [ABSTRACT FROM AUTHOR]
