Fungus isolated from dermatomycoses: a 9-month prospective study at Hospital Melaka.

INTRODUCTION: Dermatomycoses are common superficial cutaneous fungal infections which affect the skin, nails and human hairs. It affects 20 to 25% of the world population. The causative fungus varies geographically across the globe. Study on dermatomycoses is crucial to identify the aetiological fungus involved locally. The study aimed to determine the causative fungus of superficial fungal infections of the skin, nail and hair in patients presented to Hospital Melaka. METHODS: This was a prospective study conducted from 15th January 2022 till 15th October 2022 at Dermatology Clinic, Hospital Melaka. Subjects with clinical dermatomycoses were included in this study. The samples were collected from skin, nails and hairs clinically affected by tinea corporis/cruris/pedis, onychomycosis and tinea capitis respectively. A potassium hydroxide (KOH) study was performed on the sample in which the fungal hyphae/yeast positive subjects were sent for fungal culture and fungal PCR test. RESULT: A total of 222 clinical samples from skin, nails and hairs with a clinical suspicion of dermatomycoses yielded fungal hyphae/yeast in KOH. Majority of the samples were collected from skin (138, 62.2%), followed by nails (65, 29.3%) and hairs (19, 8.6%). Male to female ratio was 1.18: 1. The age ranged from 2 to 87 with the median of 55.5-yearsold. Out of 222 samples, 150 (67.6%) were fungal culture positive. From fungal culture positive samples, 87 samples were from tinea corporis, 50 samples were from onychomycoses and 13 samples were from tinea capitis. Trichophyton rubrum (39, 44.8%) was the commonest dermatophyte isolated in tinea corporis/cruris/pedis. Nondermatophyte moulds (NDM, 35, 70%) were the main fungi isolated in onychomycosis. Microsporum canis (7/53.8%) was the principal causative fungus among patients with tinea capitis. Among 150 fungal culture positive samples, 76 were fungal PCR positive. Only 38 samples consistently isolated same fungal species in both fungal culture and PCR test. CONCLUSION: Majority of tinea corporis and tinea capitis fungal culture isolated dermatophytes, especially Trichophyton rubrum and Microsporum canis, respectively. Non-dermatophyte moulds were mainly isolated in onychomycosis.

The efficacy of intense pulse light among patients with skin type III-IV in acute facial acne: The Malaysian experience.

INTRODUCTION: Twenty-seven adult patients, skin type III -V with mild to moderate acne, were recruited. IPL at wavelengths range of 420 - 600nm with triple pulses was administered every two weeks for a total of 3 sessions. Assessment of acne severity and improvement of treatment was based on Global Acne Grading System (GAGS), scoring before and after treatment for each session and patient satisfaction's using a 5-item Likert scale range at the end of session three. RESULTS: Of the 27 patients, 77.8% were female. Their ages group ranged from 18 to 35 years, and all patients had skin type III or IV. There were 14 mild acne patients and 13 moderate ones. There was a statistically significant improvement in mean acne severity score from 18.1± 4.3 at baseline to 14.3 ± 4.6 after two weeks post-IPL and 12.3 ± 4.9 after four weeks post-IPL. The result on satisfaction level of patients showed 'satisfied' in 3 patients, "very satisfied" in 5 patients; and, half of the patients (11) answered "fair" at the end of the study. Most patients tolerated well the procedure, and only 5 patients developed either post-inflammatory hyperpigmentation or skin hyperpigmentation. CONCLUSION: The IPL of wavelength of 400-600nm offers effective, safe, and well-tolerated treatment of mild to moderate acne lesions in Malaysians with skin types III-IV. The majority of subjects had a fair score on treatment satisfaction. It is recommended that reasonable expectations for clinical results be addressed with patients before hands to prevent over-expectation.

Tumour biomarkers: association with heart failure outcomes.

BACKGROUND: There is increasing recognition that heart failure (HF) and cancer are conditions with a number of shared characteristics. OBJECTIVES: To explore the association between tumour biomarkers and HF outcomes. METHODS: In 2,079 patients of BIOSTAT-CHF cohort, we measured six established tumour biomarkers: CA125, CA15-3, CA19-9, CEA, CYFRA 21-1 and AFP. RESULTS: During a median follow-up of 21 months, 555 (27%) patients reached the primary end-point of all-cause mortality. CA125, CYFRA 21-1, CEA and CA19-9 levels were positively correlated with NT-proBNP quartiles (all P < 0.001, P for trend < 0.001) and were, respectively, associated with a hazard ratio of 1.17 (95% CI 1.12-1.23; P < 0.0001), 1.45 (95% CI 1.30-1.61; P < 0.0001), 1.19 (95% CI 1.09-1.30; P = 0.006) and 1.10 (95% CI 1.05-1.16; P < 0.001) for all-cause mortality after correction for BIOSTAT risk model (age, BUN, NT-proBNP, haemoglobin and beta blocker). All tumour biomarkers (except AFP) had significant associations with secondary end-points (composite of all-cause mortality and HF hospitalization, HF hospitalization, cardiovascular (CV) mortality and non-CV mortality). ROC curves showed the AUC of CYFRA 21-1 (0.64) had a noninferior AUC compared with NT-proBNP (0.68) for all-cause mortality (P = 0.08). A combination of CYFRA 21-1 and NT-proBNP (AUC = 0.71) improved the predictive value of the model for all-cause mortality (P = 0.0002 compared with NT-proBNP). CONCLUSIONS: Several established tumour biomarkers showed independent associations with indices of severity of HF and independent prognostic value for HF outcomes. This demonstrates that pathophysiological pathways sensed by these tumour biomarkers are also dysregulated in HF.

Effect of Using a Wheeled Walker on Physical Activity and Sedentary Time in People with Chronic Obstructive Pulmonary Disease: A Randomised Cross-Over Trial.

PURPOSE: To determine the effects of providing a wheeled walker (WW) for use in the home and community, on daily physical activity (PA) and sedentary time (ST) in people with chronic obstructive pulmonary disease (COPD). METHODS: A randomised cross-over study in which participants with COPD characterised by a 6-min walk distance ≤ 450 m, who had recently finished pulmonary rehabilitation, completed two 5-week phases. During one phase, participants were provided a WW to use, whereas during the other phase, the WW was not available. The order of the phases was randomised. For the final week of each phase, measures of PA and ST were collected using wearable devices and health-related quality of life was measured using the Chronic Respiratory Disease Questionnaire (CRDQ). Wheeled walker use was also measured using an odometer attached to the device. RESULTS: 17 participants [FEV1 = median (interquartile range) 33 (25) % pred; ten males] aged mean (SD) 73 (9) years completed the study. Comparing the data collected when the WW was not available for use, the daily step count was greater (mean difference [MD] 707 steps/day (95% confidence interval [CI] 75 to 1340) and participants tended to report less dyspnoea during daily life (MD 0.5 points per item, 95% CI - 0.1 to 1.0) when WW was available. No differences were observed for ST, upright time or stepping time. The WW was used over 4504 m/week (95% CI 2746 to 6262). CONCLUSION: These data demonstrated that, when provided to selected patients with COPD, WWs increased daily step count. CLINICAL TRIAL REGISTRATION NUMBER: ACTRN12609000332224.

Novel endotypes in heart failure: effects on guideline-directed medical therapy.

Aims: We sought to determine subtypes of patients with heart failure (HF) with a distinct clinical profile and treatment response, using a wide range of biomarkers from various pathophysiological domains. Methods and results: We performed unsupervised cluster analysis using 92 established cardiovascular biomarkers to identify mutually exclusive subgroups (endotypes) of 1802 patients with HF and reduced ejection fraction (HFrEF) from the BIOSTAT-CHF project. We validated our findings in an independent cohort of 813 patients. Based on their biomarker profile, six endotypes were identified. Patients with endotype 1 were youngest, less symptomatic, had the lowest N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and lowest risk for all-cause mortality or hospitalization for HF. Patients with endotype 4 had more severe symptoms and signs of HF, higher NT-proBNP levels and were at highest risk for all-cause mortality or hospitalization for HF [hazard ratio (HR) 1.4; 95% confidence interval (CI) 1.1-1.8]. Patients with endotypes 2, 3, and 5 were better uptitrated to target doses of beta-blockers (P < 0.02 for all). In contrast to other endotypes, patients with endotype 5 derived no potential survival benefit from uptitration of angiotensin-converting enzyme-inhibitor/angiotensin-II receptor blocker and beta-blockers (Pinteraction <0.001). Patients with endotype 2 (HR 1.29; 95% CI 1.10-1.42) experienced possible harm from uptitration of beta-blockers in contrast to patients with endotype 4 and 6 that experienced benefit (Pinteraction for all <0.001). Results were strikingly similar in the independent validation cohort. Conclusion: Using unsupervised cluster analysis, solely based on biomarker profiles, six distinct endotypes were identified with remarkable differences in characteristics, clinical outcome, and response to uptitration of guideline directed medical therapy.

Cyanotic Congenital Heart Disease Modes of Presentation and Prenatal Detection

Prenatal detection of structural congenital heart disease (CHD) optimises cardiovascular stability pre-operatively and post-operative outcomes. We compared prenatal detection rates of critical CHD in units offering universal fetal anomaly scans with those offering imaging to selected women. One hundred and thirteen infants met inclusion criteria. The overall pre-natal detection rate for critical CHD was 57% of liveborn infants. It was 71% (57/80) in hospitals who offered a universal anomaly scan and 29% (9/31) in centres offering a limited service. Postnatal diagnosis was associated with PICU admission (p=0.016) and preoperative mechanical ventilation (p=0.001). One-year mortality was 10 fold higher in the postnatally diagnosed group 15% vs 1.55% (p=0.0066). There is a significant disparity between centres offering universal anomaly versus selective screening. Prenatal detection confers advantage in terms of pre-operative stability and one year survival. Failure to deliver an equitable service exposes infants with CHD to avoidable risk.

Imaging appearances of hepatic tuberculosis: experience with 12 patients.

AIM: To review computed tomography (CT), ultrasound (US), magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiogram (PTC) appearances and their diagnostic value in hepatic tuberculosis. MATERIALS AND METHODS: The imaging studies for 12 patients with biopsy-proven hepatic tuberculosis from January 2012 till March 2014 were reviewed retrospectively. These cases were confirmed via ultrasound-guided biopsy. RESULTS: The patients were aged 24-72 years. Four patients had parenchymal tuberculosis only and eight patients had mixed parenchymal and biliary duct involvement. The parenchymal tuberculosis patients showed poorly enhancing, hypodense nodules on CT with central calcification and adjacent dilated intrahepatic ducts. Most patients had multiple lesions except for two patients with a single lesion. The size of the lesions ranged from 0.5 to 6 cm. Seven patients with biliary duct involvement showed a hilar strictures involving the intrahepatic ducts and common bile duct. Nine of the patients showed hilar stricture with atrophy of the ipsilateral lobe of the liver and compensatory hypertrophy of the contralateral lobe. Hepatolithiasis was seen in five patients. Tuberculous lung involvement was seen in seven patients. CONCLUSION: The presence of calcified and hypodense nodules with biliary duct dilatation associated with lobar atrophy were the most consistent features of hepatic tuberculosis, especially in the presence of active lung disease.

Determinants and clinical outcome of uptitration of ACE-inhibitors and beta-blockers in patients with heart failure: a prospective European study.

INTRODUCTION: Despite clear guidelines recommendations, most patients with heart failure and reduced ejection-fraction (HFrEF) do not attain guideline-recommended target doses. We aimed to investigate characteristics and for treatment-indication-bias corrected clinical outcome of patients with HFrEF that did not reach recommended treatment doses of ACE-inhibitors/Angiotensin receptor blockers (ARBs) and/or beta-blockers. METHODS AND RESULTS: BIOSTAT-CHF was specifically designed to study uptitration of ACE-inhibitors/ARBs and/or beta-blockers in 2516 heart failure patients from 69 centres in 11 European countries who were selected if they were suboptimally treated while initiation or uptitration was anticipated and encouraged. Patients who died during the uptitration period (n = 151) and patients with a LVEF > 40% (n = 242) were excluded. Median follow up was 21 months. We studied 2100 HFrEF patients (76% male; mean age 68 ±12), of which 22% achieved the recommended treatment dose for ACE-inhibitor/ARB and 12% of beta-blocker. There were marked differences between European countries. Reaching <50% of the recommended ACE-inhibitor/ARB and beta-blocker dose was associated with an increased risk of death and/or heart failure hospitalization. Patients reaching 50-99% of the recommended ACE-inhibitor/ARB and/or beta-blocker dose had comparable risk of death and/or heart failure hospitalization to those reaching ≥100%. Patients not reaching recommended dose because of symptoms, side effects and non-cardiac organ dysfunction had the highest mortality rate (for ACE-inhibitor/ARB: HR 1.72; 95% CI 1.43-2.01; for beta-blocker: HR 1.70; 95% CI 1.36-2.05). CONCLUSION: Patients with HFrEF who were treated with less than 50% of recommended dose of ACE-inhibitors/ARBs and beta-blockers seemed to have a greater risk of death and/or heart failure hospitalization compared with patients reaching ≥100%.

Discovery of coarctation of the aorta following renal doppler sonography.

Coarctation of the aorta (CoA) is present in 0.4% of live births and in 7% of patients with congenital heart disease. While there may be florid presentations of congestive heart failure in the neonatal period, the diagnosis during adulthood is often delayed. We encountered a 20-year-old woman who was discovered to be hypertensive on routine check-up. Following bilateral abnormal renal doppler sonography, MR angiogram revealed a short-segment stenosis of the descending thoracic aorta. Review of her chest radiograph showed a small aortic knuckle. This case highlights an unconventional algorithm in diagnosing aortic coarctation in adulthood.

Posttraumatic stress disorder in the World Mental Health Surveys.

BACKGROUND: Traumatic events are common globally; however, comprehensive population-based cross-national data on the epidemiology of posttraumatic stress disorder (PTSD), the paradigmatic trauma-related mental disorder, are lacking. METHODS: Data were analyzed from 26 population surveys in the World Health Organization World Mental Health Surveys. A total of 71 083 respondents ages 18+ participated. The Composite International Diagnostic Interview assessed exposure to traumatic events as well as 30-day, 12-month, and lifetime PTSD. Respondents were also assessed for treatment in the 12 months preceding the survey. Age of onset distributions were examined by country income level. Associations of PTSD were examined with country income, world region, and respondent demographics. RESULTS: The cross-national lifetime prevalence of PTSD was 3.9% in the total sample and 5.6% among the trauma exposed. Half of respondents with PTSD reported persistent symptoms. Treatment seeking in high-income countries (53.5%) was roughly double that in low-lower middle income (22.8%) and upper-middle income (28.7%) countries. Social disadvantage, including younger age, female sex, being unmarried, being less educated, having lower household income, and being unemployed, was associated with increased risk of lifetime PTSD among the trauma exposed. CONCLUSIONS: PTSD is prevalent cross-nationally, with half of all global cases being persistent. Only half of those with severe PTSD report receiving any treatment and only a minority receive specialty mental health care. Striking disparities in PTSD treatment exist by country income level. Increasing access to effective treatment, especially in low- and middle-income countries, remains critical for reducing the population burden of PTSD.

Exploratory analysis of factors associated with venous thromboembolism in Victorian acute traumatic spinal cord-injured patients 2010-2013.

STUDY DESIGN: A retrospective medical records audit. OBJECTIVES: To investigate the presence of venous thromboembolism (VTE) events following acute traumatic spinal cord injury (SCI) and the association between VTE events and a number of postulated risk factors. SETTING: The state-wide SCI service in Victoria Australia (Victorian Spinal Cord Service) located at Austin Hospital Melbourne Australia. METHODS: A retrospective electronic medical records file audit was performed of all patients admitted to VSCS between 2010 and 2013 with an acute traumatic SCI. The outcome measure was the presence of VTE (deep venous thrombosis (DVT), pulmonary embolism (PE) or both). Data were also collected on a variety of established and postulated risk factors for VTE post SCI. RESULTS: VTE events occurred in 21.2% of acute SCI patients during the hospitalisation of the patient. Statistically significant associations were found between the presence of VTE events and increased weight, male sex, completeness of motor paralysis, length of stay (LOS), associated pelvic or lower limb fracture and delayed admission to the state-wide spinal cord service. CONCLUSION: Further studies are warranted to investigate whether in other SCI centres the risk of VTE in acute SCI patients is similarly associated with the risk factors identified in our study. A study exploring whether giving acute SCI patients of heavier weight a larger dose of chemical thromboprophylaxis is safe and efficacious is also warranted.

Measurement of daily physical activity using the SenseWear Armband: Compliance, comfort, adverse side effects and usability.

Little is known about the acceptability of wearing physical activity-monitoring devices. This study aimed to examine the compliance, comfort, incidence of adverse side effects, and usability when wearing the SenseWear Armband (SWA) for daily physical activity assessment. In a prospective study, 314 participants (252 people with COPD, 36 people with a dust-related respiratory disease and 26 healthy age-matched people) completed a purpose-designed questionnaire following a 7-day period of wearing the SWA. Compliance, comfort levels during the day and night, adverse side effects and ease of using the device were recorded. Non-compliance with wearing the SWA over 7 days was 8%. The main reasons for removing the device were adverse side effects and discomfort. The SWA comfort level during the day was rated by 11% of participants as uncomfortable/very uncomfortable, with higher levels of discomfort reported during the night (16%). Nearly half of the participants (46%) experienced at least one adverse skin irritation side effect from wearing the SWA including itchiness, skin irritation and rashes, and/or bruising. Compliance with wearing the SWA for measurement of daily physical activity was found to be good, despite reports of discomfort and a high incidence of adverse side effects.

Uncontrolled hypertension, palpitation and sweating in young female - A rare cause.

Extra-adrenal /retroperitoneal paraganglioma is a rare cause of hypertension in young with increased incidence of metastasis as compared to adrenal pheochromocytoma. We present a case of a young female with history of headache, nausea/vomiting, palpitations, uncontrolled hypertension, heat intolerance and diaphoresis. The 24-hour urine catecholamine levels were elevated. Clinical diagnosis of pheochromocytoma was made and further evaluation with Computed Tomography (CT) scan of the adrenals revealed extradrenal para-aortic retroperitoneal mass in keeping with paraganglioma. Gallium-68 DOTATE positron emission tomography-CT scan (PET-CT) confirmed the diagnosis without evidence of metastatic foci.

Pelvic floor spasm as a cause of voiding dysfunction.

PURPOSE OF REVIEW: Pelvic floor disorders can present with lower urinary tract symptoms, bowel, sexual dysfunction, and/or pain. Symptoms of pelvic muscle spasm (nonrelaxing pelvic floor or hypertonicity) vary and can be difficult to recognize. This makes diagnosis and management of these disorders challenging. In this article, we review the current evidence on pelvic floor spasm and its association with voiding dysfunction. RECENT FINDINGS: To distinguish between the different causes of voiding dysfunction, a video urodynamics study and/or electromyography is often required. Conservative measures include patient education, behavioral modifications, lifestyle changes, and pelvic floor rehabilitation/physical therapy. Disease-specific pelvic pain and pain from pelvic floor spasm needs to be differentiated and treated specifically. Trigger point massage and injections relieves pain in some patients. Botulinum toxin A, sacral neuromodulation, and acupuncture has been reported in the management of patients with refractory symptoms. SUMMARY: Pelvic floor spasm and associated voiding problems are heterogeneous in their pathogenesis and are therefore often underrecognized and undertreated; it is therefore essential that a therapeutic strategy needs to be personalized to the individual patient's requirements. Therefore, careful evaluation and assessment of individuals using a multidisciplinary team approach including a trained physical therapist/nurse clinician is essential in the management of these patients.

Clinical associations of anosognosia in mild cognitive impairment and Alzheimer's disease.

AIMS AND OBJECTIVE: While loss of insight of cognitive deficits is a common phenomenon in patients with Alzheimer's disease (AD), there is a lack of consensus regarding the presence of impaired insight among patients with mild cognitive impairment (MCI). We aim to investigate the clinical, cognitive, and behavioral associations of anosognosia in AD and MCI subjects. METHODS: A consecutive series of 87 subjects (30 healthy older patients, 21 MCI, and 36 AD) each accompanied by a caregiver, underwent clinical assessment including the evaluation of insight using the Anosognosia Questionnaire for Dementia (AQD). We also separately assessed Intellectual Function (AQD-IF) and Behavior domains of the AQD scale. Regression models were subsequently used to investigate associations of AQD scores with cognitive and other neuropsychiatric symptoms, including depression and apathy. RESULTS: Both AD and MCI groups demonstrated significant anosognosia compared with the healthy control group. In the AD group, 55.6% had "Mild Anosognosia," and 27.8% had "Severe Anosognosia." In the MCI group, 42.9% showed "Mild Anosognosia," and 9.5% had "Severe Anosognosia." Greater levels of AQD-Total and AQD-IF were associated with lower Mini-mental state examination and higher apathy scores in the AD group. In the MCI group, caregiver burden was significantly associated with AQD-Total (p = 0.016) and AQD-IF (p = 0.039). CONCLUSION: The results indicated that anosognosia is common in both AD and MCI patients and associated with cognitive dysfunction and apathy in AD. The findings of this study warrant further research to delineate the mechanisms of anosognosia as it poses a challenge to treatment outcomes.

Methylnaltrexone to prevent intrathecal morphine-induced pruritus after Caesarean delivery: a multicentre, randomized clinical trial.

BACKGROUND: Intrathecal morphine-induced pruritus is a very common side-effect that is difficult to prevent or treat. Central and peripheral mechanisms are believed to be involved. The aim of this study was to determine if a peripherally acting, µ-opioid antagonist would reduce morphine-induced pruritus. METHODS: We conducted a multicentre, randomized, blinded, placebo-controlled trial of women having elective Caesarean section under spinal anaesthesia with intrathecal morphine 100 µg. After delivery, participants received either subcutaneous methylnatrexone bromide 12 mg (MNTX group, n=69) or saline (placebo group, n=68). Pruritus, nausea, pain, analgesic use, and side-effects were assessed at 2, 4, 8, and 24 h. The primary outcome was the severity of pruritus (0-10 score). RESULTS: One hundred and thirty-seven women completed the study, with five major protocol violations. There was no statistically significant difference between the MNTX and placebo groups for the median (IQR) pruritus AUC scores [24 (9-47) vs 36 (11-68), median difference 8.5, 95% confidence interval (CI) 0-20, P=0.09] or the worst pruritus score [3 (2-7) vs 5 (2-6), median difference 1, 95% CI 0-2, P=0.24]. The incidence of pruritus was 84% in the MNTX group and 88% in the placebo group (P=0.48). Analgesic and gastrointestinal outcomes did not significantly differ between the groups. CONCLUSIONS: A single dose of subcutaneous methylnaltrexone bromide 12 mg did not reduce the overall severity or incidence of pruritus. In this study, treatment with a peripherally acting µ-opioid antagonist was generally ineffective against intrathecal morphine-induced pruritus, but a small clinical effect cannot be excluded.

Effects of two different knee tape procedures on lower-limb kinematics and kinetics in recreational runners.

The purpose of this study was to compare the effects of Mulligan's tape (MT) and kinesio tape (KT) with no tape (NT) on hip and knee kinematics and kinetics during running. Twenty-nine female recreational runners performed a series of 'run-throughs' along a 10-m runway under the three taping conditions. Two force plates and a 14-camera Vicon motion analysis system (Oxford Metrics, Inc., Oxford, UK) captured kinematic and kinetic data for each dependent variable from ground contact to toe off. Comparisons of each dependent variable under three taping conditions were assessed through Statistical Package for the Social Sciences (SPSS; SPSS, Inc., Chicago, Illinois, USA; P-value < 0.01) using repeated measure analyses of variance. For each dependent variable with a P-value < 0.01, repeated measures with pairwise comparisons and Bonferroni adjustment were conducted to compare the three taping conditions. MT induced a significant reduction in anterior and posterior hip forces, knee flexion angular velocity, knee extensor moments, and hip flexion and extension moments compared with NT and KT (P = 0.001). There was no difference in hip or knee, kinematics or kinetics, between KT and NT (P = 1.000). MT appears to influence hip and knee biomechanics during running in an asymptomatic sample, whereas KT appeared to be biomechanically not different from NT.
