ABSTRACT
INTRODUCTION: Spirometry is considered as a 'gold standard' for diagnosis of asthma. Impulse oscillometry (IOS) is an alternative diagnostic tool which requires less cooperation by the participants. We performed a study to determine the correlation of IOS with bronchodilator reversibility from spirometry in asthmatic participants. We studied the correlation between forced expiratory flow (FEF25%-75%) and differences between the resistance at 5Hz and 20Hz (R5-R20) in small airway disease (SAD) and the proportion of SAD diagnosed using IOS. MATERIALS AND METHODS: This was a cross-sectional study involving 82 asthmatic participants in Hospital Canselor Tuanku Muhriz (HCTM), Universiti Kebangsaan Malaysia (UKM) conducted between December 2020 till January 2022. Participants performed pre- and post-bronchodilator IOS and spirometry within the same day. Correlation between spirometry and IOS parameters and FEF25%-75% with IOS were determined and analysed. RESULTS: The change of forced expiratory volume in 1 second (FEV1) was statistically correlated with a change of R5 in IOS. A decrement of 14.5% in R5 can be correlated with positive bronchodilator response (BDR) with a sensitivity of 63.9% and specificity of 60.9%, p=0.007. Pre-bronchodilator FEF25%-75% correlated with all parameters of SAD in IOS, e.g., R5-R20, reactance at 5Hz (X5) and area of reactance (AX), p < 0.05. IOS detection for SAD is higher compared to FEF25%-75% in the BDR negative group (91.3% vs 58.7%). CONCLUSION: IOS detected both bronchodilator reversibility and SAD hence can be considered as an alternative tool to spirometry for diagnosis of asthma in adults. IOS detected SAD more than FEF25%-75%, especially in BDR-negative group.

INTRODUCTION: Fluoroscopic-guided transbronchial lung biopsy (FG-TBLB) is routinely performed via bronchoscopy to diagnose focal peripheral lesions and diffuse lung disease. Identifying the risk factors of FG-TBLB-related pneumothorax can assist the operator in taking pre-emptive measures to prepare for this potential complication. MATERIALS AND METHODS: We retrospectively analysed data from 157 patients who underwent FG-TBLB, with the primary outcome being procedure-related pneumothorax. We assessed several risk factors for pneumothorax following FG-TBLB: patient characteristics, location of biopsy, number of biopsies and computed tomography pattern. Univariate and multivariate logistic regression analyses were performed. RESULTS: One-hundred fifty-seven patients were included [mean (SD) age 57.9 (16.2) years; 60.5% male]. The most common location for FG-TBLB was the right upper lobe (n=45, 28.7%). The mean (SD) number of biopsy samples was 6.7 (2.1). Radiographic evidence of pneumothorax was reported in 12 (7.6%) patients, with 11 of those requiring intercostal chest tube intervention (mean air leak time: 5.7 days and 1 had persistent air leak requiring autologous blood patch pleurodesis. None experienced pneumothorax recurrence. Female gender and upper lobe location of the biopsy were identified as predisposing factors for pneumothorax. In the multivariable analysis, upper lobe biopsies were associated with a higher risk of pneumothorax (OR 0.120; 95% CI 0.015-0.963; p = 0.046). CONCLUSION: The overall rate of pneumothorax is low. We recognise the increased risk of pneumothorax associated with upper lobe biopsy. These findings suggest that clinicians should exercise caution when performing FGTBLB in this region and consider alternative biopsy locations whenever feasible. We suggest adequate planning and preparation should be implemented to minimise the risk of pneumothorax following FG-TBLB.

INTRODUCTION: The correlation between pulmonary function and hypertension remains ambiguous. This study therefore determined the relationship between pulmonary function and hypertension among adult subgroup in Malaysia. MATERIALS AND METHODS: Data for this study were obtained from an ongoing Prospective Urban Rural Epidemiology- Rural Urban Study (PURE RUS) , which is a prospective cohort study done by MARA University of Technology (UiTM) Medical Faculty research team to track risk factors, changing lifestyles, and chronic diseases in rural and urban population. The inclusion criteria included: Malaysian citizen, age 18-80 years, not on any anti-hypertensive agents, and able to perform lung function test. 1640 participants satisfied the criteria and were recruited in this study. RESULTS: From the studied population, males comprised 43.5% of them and female comprised 56.5%. A significant inverse relationship was found between pulmonary function and systolic blood pressure in both sexes measured by forced vital capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1). A substantial inverse relationship was also found between pulmonary function and age, and there was a profound positive association between blood pressure and age. No major disparities were significant in pulmonary function between hypertensive and age-matched normotensive participants. CONCLUSION: Even though a substantial inverse relationship was evident between systolic blood pressure and pulmonary function, its precise clinical importance needs to be further explored particularly when age can influence both pulmonary function and blood pressure. Clearly, the impact of age has to be removed before FVC can be used as a prognosticator of hypertension.

OBJECTIVE: This study assessed the delivery of tiotropium via Respimat® in addition to standard care of treatment among chronic obstructive pulmonary disease (COPD) patients. We study the efficacy, clinical outcome of handling inhaler device, rate of exacerbation and frequency of hospital admission of tiotropium via Respimat® with and without the use of a spacer (AeroChamber®). METHODS: Randomised, open-label study of COPD patients which was randomised into two groups: spacer or nonspacer groups using tiotropium via Respimat®. Treatment with their pre-existing inhalers continued. Subjects were assessed at weeks 0, and 8 for forced expiratory volume in 1 second (FEV1), COPD assessment tool (CAT), St. George's Respiratory Questionnaire (SGRQ), and satisfaction questionnaire. RESULTS: We enrolled 96 subjects: 49 in the spacer group and 47 in the non-spacer group. The mean predicted FEV1 in spacer group was 54.48% at baseline and 57.5l% at week 8: p=0.011. In the non-spacer groups, FEV1 was 54.48% at baseline and 59.20% with a mean increment of 4.72 in both groups: p=0.002. There were no difference of exacerbation rates and hospital admission between both groups. At baseline, mean CAT score in the spacer group was 14.01 which improved to 9.80 (p<0.001) and 14.01 to 8.80 (p<0.001) in the non-spacer group. SGRQ total score reduced in both groups with mean difference of 3.1 (p<0.001) and 3.7: (p<0.001) at weeks 0 to 8. CONCLUSION: There was no difference between exacerbation and hospital admissions between both groups. There was no difference in FEV1, CAT and SQRQ score using Tiotropium via Respimat® with or without a spacer.

Pulmonary alveolar proteinosis (PAP) is a rare disease and its prognosis can be improved by whole lung lavage (WLL). Herein, we present three cases with idiopathic PAP treated successfully with either single or double WLL in the same setting. All three of them presented with exertional dyspnoea with radiographic findings of pulmonary infiltrates. They showed a marked clinical and physiologic improvement post WLL. Two of them were in remission. These three cases were diagnosed using different lung biopsy modalities, including video-assisted thoracoscopic lung biopsy, computed tomography-guided percutaneous transthoracic tru-cut needle lung biopsy, and transbronchial forceps lung biopsy (TBLB), respectively. The current cases have shown that TBLB may provide adequate diagnostic yield, and the invasive surgical lung biopsy may not be necessary to achieve a definitive diagnosis.

Introduction: Knee injuries largely vary including cartilaginous, ligamentous, bony, and tendinous injuries. Greatest of the reported knee injuries associated with in a non-contact method includes mainly the anterior cruciate ligament (ACL). Additionally, medial and lateral menisci act as shock absorbers with an additional role in stabilizing the joint which can be or partially or totally torn. The current study aimed to assess athletes' knowledge and attitude concerning the meniscus, meniscal injury, and management. Methodology: A descriptive cross-sectional study was conducted to achieve the objectives. A pre-structured electronic questionnaire was used to collect the data, covered participants socio-demographic data, personal and family history of meniscus injury and surgery, physical activity during past year, and also knowledge regarding the meniscal injury and management. Results: A total of 448 athletes fulfilling the inclusion criteria completed the study questionnaire. Participants 'age ranged from 18 to 60 years with mean age of 26.7 ± 7.7 years old. A total of 256 (57.1%) participants were males. Exact of 21 participants had meniscus surgery. As for family history, 75 (16.7%) had family history of meniscus injury. Exact of 95 (21.2%) athletes had good knowledge level, while vast majority (78.8%; 353) had poor knowledge level. Conclusions: In conclusion, the study showed that the estimated rate of meniscus injury and surgery was not high (within the international range). The participants' knowledge regarding meniscus injury and meniscus surgery with its related management was unsatisfactory, where 1 out of each 5 was knowledgeable.
ABSTRACT
Tuberculosis (TB) is a common communicable disease. Active TB infection may be complicated by both venous and arterial thrombosis which are often under-recognised. We report two patients with incidental TB associated thrombosis involving different venous systems. Both responded to anticoagulant and anti-tuberculous therapy (ATT). Patients with tuberculosis are at risk of VTE and careful monitoring for venous thromboembolism (VTE) is needed during ATT. Our case illustrates the importance of having a high index of suspicion for silent VTE as it may complicate active TB infection.

INTRODUCTION: Continuous Positive Airway Pressure (CPAP) is required for obstructive sleep apnoea (OSA). Thisstudy compares the efficacy between Fixed Pressure CPAP (Fixed CPAP) and Auto-adjusting Pressure (APAP) based on Apnoea Hypopnoea Index (AHI), Epworth Sleepiness Score (ESS) among patients with symptomatic OSA and to ascertain their CPAP preference. METHODS: This is a prospective, randomised, crossover, single-blinded study conducted from February 2018 to February 2019 among adult subjects attending respiratory clinic Universiti Kebangsaan Malaysia Medical Centre (UKMMC). RESULTS: Forty-six subjects were recruited with 27 males (58.7%). The mean age was 54 (+11) year old. The baseline median Body Mass Index (BMI) was 34.2 kg/m2 (Interquartile Range IQR: 30.8 kg/m2 -41.7 kg/m2); baseline median AHI 28.8 /hour (IQR 21.2/hour-54.0/hour); andbaseline median ESS 15 (IQR 13-16). After intervention, the median AHI was 5.0 / hour (IQR 4.2/hour-6.0/hour) at fixed CPAP arm; APAP arm was 5.5/ hour (IQR 4.2/hour-6.3/hour); p<0.01. The median ESS at fixed CPAP arm was 2 (IQR 0-3); APAP arm was 2 (IQR 1-3); p < 0.01. Those who preferred APAP were 22 subjects (47.8%) and had median optimal CPAP pressure 13.0 cmH2O (IQR 12.0 cmH2O -13.5 cmH2O); 24 subjects (52.2%) who preferred Fixed CPAP had median optimal CPAP pressure 8.0 cmH2O (IQR 6.3 cmH2O -8.7 cmH2O); p<0.01. Median baseline BMI was 37.6 kg/m2 (IQR 30.8 kg/m2 -43.0 kg/m2) for those who preferred APAP and 32.3 kg/m2 (IQR 30.8 kg/m2 - 38.4 kg/m2) for subjects preferred Fixed CPAP; p=0.03. DISCUSSION: Fixed CPAP maybe considered as first line therapy for symptomatic moderate and severe OSA with titrated optimal CPAP pressure less than 8 cmH2O and BMI less than 32.3 kg/m2; based on subjects' preference. Baseline AHI and average daily CPAP usage was not statisticallysignificant in affecting patient preference between fixed and auto adjusting CPAP. This is the first study of its kind conducted in Malaysia.

INTRODUCTION: Knowledge and adequate practice of preventive measures among health care workers (HCWs) are important to reduce the risk of COVID-19 transmission. METHODS: A cross-sectional study was conducted among doctors and nurses in the medical department in Pusat Perubatan Universiti Kebangsaan Malaysia between November 18, 2020 and December 18, 2020 during the third wave of COVID-19 epidemic in Malaysia. We studied the knowledge and practice of preventive measures of COVID-19 among doctors and nurses in the COVID-19 or sudden acute respiratory infection (SARI) wards and general medical wards. Data was collected using a validated self-designed google form online-questionnaire. RESULTS: A total of 407 subjects completed the study and 80.8% were females; 55.8% were aged between 30-39 years; 46.4% were medical doctors. The main source of COVID-19 knowledge was the Ministry of Health Malaysia (MOH) website (35.1%). Majority (97%) had sufficient knowledge and 82% practiced proper preventive measures. Doctors had a higher mean knowledge score compared to nurses (p < 0.001). HCWs working in COVID-19 or SARI wards scored higher in knowledge questions compared to those in the general medical wards (p = 0.020). Nurses practiced better preventive measures (p < 0.001). Good knowledge could not be predicted based on professions (OR: 0.222, 95% CI: 0.048 - 1.028, p = 0.054). Majority were unable to recall the proper steps of donning (85.8%) and doffing (98.5%). CONCLUSIONS: Although majority had good knowledge and practiced proper preventive measures, there was a poor recall in donning and doffing steps regardless of place of practice. The MOH website is a useful platform for tailored continuous medical education and regular updates on COVID-19. Regular training and retraining on donning and doffing of PPE is needed to bridge this gap.

BACKGROUND: COVID-19 has the potential to affect the mental health of health care workers (HCWs). It is known that HCWs who serve as front-liners during the COVID-19 pandemic experience stress and have the fear of contracting the infection. Little is known of how being a positive contact affects HCWs. OBJECTIVE: We examined the experience of HCWs who were quarantined following a close unprotected contact with a COVID-19 positive colleague and explore the psychological impact especially as the timing of the quarantine coincided with the Eid (annual Muslim festival) celebration in Malaysia. METHODS: This was a cross-sectional on-line questionnaire study, involving HCWs exposed to a COVID-19 positive colleague in Universiti Kebangsaan Malaysia Medical Centre, a teaching hospital. Data on demographics, levels of depression, anxiety and stress using a validated depression, anxiety, and stress scale (DASS-21) questionnaire, aspects of quarantine, wearing of masks, hand hygiene practice and swab experience were collected. RESULTS: Twenty-two HCWs participated. Eighteen (81.8%) were between 30-39 years and 17 (77.3%) were women. Majority 19 (86.3%) were Malays. There were twelve (54.5%) medical officers, 5 (22.7%) specialists and 5(22.7%) allied health staff. Eighteen out of 22 (81.8%) felt they were able to do home quarantine adequately. All tested negative with a mean (Standard Deviation) hour of contact of 2.56±2.38 hours. Eighteen reported their biggest concern was infecting their families. CONCLUSION: HCWs undergoing contact swabbing and quarantine are vulnerable to depression, anxiety and stress. The ability of the HCW to adequately home quarantine should not be taken for granted. Psychological support should be offered to HCWs who are positive contacts.

BACKGROUND AND OBJECTIVE: Coronavirus Disease 2019 (COVID- 19) was first reported in Malaysia in March 2020. We describe here the clinical characteristics and computed tomography (CT) patterns in asymptomatic young patients who had laboratory-confirmed COVID-19. METHODS: This is a retrospective observational study where 25 male in-patients with laboratory-confirmed COVID-19 in Hospital Canselor Tuanku Muhriz. Demographics, clinical data and CT images of these patients were reviewed by 2 senior radiologists. RESULTS: In total there were 25 patients (all males; mean age [±SD], 21.64±2.40 years; range, 18-27 years). Patients with abnormal chest CT showed a relatively low normal absolute lymphocytes count (median: 2.2 x 109/L) and absolute monocyte count (median: 0.5 x 109/L). Lactate dehydrogenase was elevated in 5 (20%) of the patients. The procalcitonin level was normal while elevated levels of alanine aminotransferase, total bilirubin, platelet and C-reactive protein were common. Baseline chest CT showed abnormalities in 6 patients. The distribution of the lesions were; upper lobe 3 (12%) lower lobe 3 (12%) with peripheral distribution 4 (16%). Of the 25 patients included, 4 (16%) had ground glass opacification (GGO), 1 (4%) had a small peripheral subpleural nodule, and 1 (4%) had a dense solitary granuloma. Four patients had typical CT features of COVID-19. CONCLUSION: We found that the CT imaging showed peripheral GGO in our patients. They remained clinically stable with no deterioration of their respiratory symptoms suggesting stability in lung involvement. We postulate that rapid changes in CT imaging may not be present in young, asymptomatic, non-smoking COVID-19 patients. Thus the use of CT thoraxfor early diagnosis may be reserved for patients in the older agegroups, and not in younger patients.

In the past, many case series have reported the effectiveness of autologous blood patch pleurodesis (ABPP) in recurrent secondary spontaneous pneumothorax (SSP), particularly in those who were unfit for surgery. We describe two cases of persistent air leak in pneumoconiosis and pulmonary fibrosis with bronchiectasis, whereby the techniques employed had improved the success rate of ABPP. The determining factors that lead to the success of ABPP were determined by the volume of autologous blood instilled, Trendelenburg position post instillation, and early chest physiotherapy with mobilisation by application of pneumostat.

The indwelling pleural catheter (IPC) is a 16-Fr-multifenestrated catheter. It has become an accepted practice in the management of malignant pleural effusion, especially in patients with non-expandable lung. However, IPC blockage or not draining is common. A 53-year-old female with malignant pleural effusion presented to us with blocked IPC and symptomatic pleural loculation one month after IPC insertion. After failing saline flushing and low-pressure wall suction, intrapleural alteplase was instituted through the IPC with a favourable outcome, and she continued to drain daily thereafter. The present case highlights the safety of intrapleural alteplase via IPC in the non-expandable lung.

There have been few but timely studies examining the role of air pollution in lung cancer and survival. The Southeast Asia haze is a geopolitical problem that has occurred annually since 1997 in countries such as Malaysia, Singapore and Indonesia. To date, there has been no study examining the impact of the annual haze in the presentation of lung cancer. Data on all lung cancers and respiratory admissions to Universiti Kebangsaan Malaysia Medical Centre (UKMMC) from 1st January 2010 to 31th October 2015 were retrospectively collected and categorized as presentation during the haze and non-haze periods defined by the Department of Environment Malaysia. We report a lung cancer incidence rate per week of 4.5 cases during the haze compared to 1.8 cases during the non-haze period (p<0.01). The median survival for subjects presenting during the haze was 5.2 months compared to 8.1 months for the non-haze period (p<0.05). The majority of subjects diagnosed during the haze period initially presented with acute symptoms. Although this study could not suggest a cause and effect relationship of the annual haze with the incidence of lung cancer, this is the first study reporting a local air pollution-related modifiable determinant contributing to the increase in presentation of lung cancer in Southeast Asia.

Electromagnetic navigational bronchoscopy (ENB), one of the methods of navigational bronchoscopy is an advanced diagnostic tool allowing tissue sampling at the lung peripheries which were previously accessible only by computed tomography (CT) guidance or video-assisted thoracoscopic surgery (VATS). We report a 53-year-old man who presented with a cough and dyspnea with constitutional symptoms for one month. CT thorax revealed multiple bilateral peripheral lung nodules and there were no endobronchial lesions on flexible bronchoscopy. ENB was performed using a loan machine from Veran navigational technology. Biopsy successfully revealed small cell carcinoma of the lung thus preventing him from undergoing a more invasive diagnostic procedure. This case highlights the utility of ENB in the evaluation of peripheral lung nodules that were inaccessible by conventional bronchoscopy. This is one of the first few successful applications of Veran ENB in Asia.

A 36-year-old lady presented with four episodes of right sided pneumothorax during pregnancy requiring multiple chest drain insertion. It was complicated with persistent air leak despite low pressure high volume suction applied to the chest drainage. She delivered safely through spontaneous vaginal delivery with chest drainage. Further imaging by high resolution computed tomography (HRCT) scan of thorax done revealed bilateral scattered pulmonary cysts and sub pleural bullae and was later followed up with respiratory unit. She had no further episodes of pneumothorax postpartum. This case highlights the vital importance of prompt recognition and management of pneumothorax in pregnancy as the patient involved is at higher risk for acute respiratory failure leading to maternal and/or foetal mortality. It is essential for early involvement of obstetric team and to expedite the delivery for a better perinatal and maternal outcome.

Purple urine bag syndrome (PUBS), as the name implies produces purplish discoloration of the urine. It is commonly observed among elderly women with constipation, and individuals with long term catheter in the setting of urinary tract infection (UTI). From the literature research, there were no publications on PUBS in Malaysia; however we believe that it is underreported. We present a unique case of this rare condition occurring in a 68-year-old man, a nursing home resident on long term urinary catheter. The urine cleared after hydration, antibiotic therapy and replacement of the catheter.
ABSTRACT
Sixty-three Arabic patients (16 males and 47 females) with thyroid toxic and nontoxic goiter who attended the endocrinologist in Nuclear Medicine Hospital and Al Yarmok Nuclear Medicine Department in Baghdad, Iraq were examined for thyroid peroxidase (TPO) gene mutations. A total of ten heterozygous mutations have been identified in the human TPO gene associated with thyroid toxic and nontoxic goiter. These mutations involved transition or transversion of cysteine either by thymine or guanine at the position 1708 of the exon 10 (c.1708C>T) and the position 1978 of the exon 11 (c.1978C>G). From a total of ten detected mutations, two c.1978C>G mutations were detected in nontoxic goiter patients and eight (two c.1708C>T and six c.1978C>G mutations) were detected in toxic goiter. In conclusion, this study identified ten TPO mutations associated with toxic and nontoxic goiter that have not been yet reported in Iraq, and most of them are detected among females (90 %) and adults age between 30 and 50 years old (80 %).
