Clinical experience with extensively Drug Resistant
tuberculosis (XDR-TB) has not been reported in Malaysia
before. We describe the clinical characteristics, risk factors,
progress and therapeutic regimen for a healthcare worker
with XDR-TB, who had failed therapy for multidrug resistant
TB (MDR TB) in our institution. This case illustrates the risk
of TB among healthcare workers in high TB-burden settings,
the importance of obtaining upfront culture and
susceptibility results in all new TB cases, the problem of
acquired drug resistance developing during MDR-TB
treatment, the challenges associated with XDR-TB treatment
regimens, the value of surgical resection in refractory cases,
and the major quality of life impact this disease can have on
young, economically productive individuals.

Objectives: This study was carried out to ascertain the aetiology of exudative pleural effusions
when other diagnostic investigations such as pleural fluid and sputum examination for cytology and
acid fast bacilli fail to yield a definitive diagnosis and to differentiate between tuberculosis and
malignancy in cases suspicious of malignancy. Methods: Pleuroscopic biopsies were obtained in
219 cases by Chest Physicians in the endoscopy suite using flexi-rigid fiber-optic pleuroscopes.
Histological sections were stained with H&E and microscopic examination performed. Ziehl-Nielsen
stain for acid fast bacilli was performed in all suspected tuberculosis cases and immunohistochemistry
for Thyroid transcription factor 1 and other markers were carried out for all cases suspicious of
malignancy. Results: Adequate biopsy material for interpretation was obtained in 210 (95.9%) of
219 cases. Histopathology revealed 79 (37.6%) cases were tuberculosis, 64 (30.5%) were malignant
(primary from lung and other sites), 62 (29.5%) were non-specific inflammation and 5 (2.4%) were
empyema. A definitive diagnosis of tuberculosis, malignancy and empyema was obtained in 70.5%
of cases. Tuberculosis was encountered in a younger age-group than malignancy. Mean age for
tuberculosis patient was 49 years while for malignant patients was 63 years. The majority (79.6%)
of malignances encountered were metastatic lung adenocarcinoma.

Background:
In the absence of significant pleural effusion, conventional medical thoracoscopy (MT) is often not feasible due to the risk of lung injury. Dry MT mitigates these risks by inducing artificial pneumothorax through needle insufflation or blunt dissection. Although the Veress needle is commonly used by surgeons to create pneumoperitoneum before laparoscopic surgeries, its application in dry MT has not been widely reported in recent times.
Methods:
We report on a series of 31 patients who underwent dry MT with artificial pneumothorax induction using Veress needle under thoracic ultrasonography (TUS) guidance. A procedure was considered technically successful if it met all the following criteria: successful pneumothorax induction, allowing smooth insertion of the semi-rigid thoracoscope; absence of immediate significant procedural-related complications; and no delayed complications such as persistent air leaks, defined as leakage lasting more than 5 days necessitating extended chest tube placement.
Results:
Complete pneumothorax induction was achieved in 25 cases, resulting in an 80.6% technical success rate; however, biopsies were successfully performed in all cases. The most frequent histopathological diagnoses were malignancy (n=9, 29.0%), followed by inflammatory pleuritis (n=8, 25.8%) and tuberculosis (n=8, 25.8%). No procedural complications were reported.
Conclusion
These results indicate that TUS-guided dry MT utilizing a Veress needle is technically feasible and secure when performed by experienced MT practitioners in TUS.

Tuberculosis and Respiratory Diseases 2023;86(4):284-293
Background:
Attitudes towards smoking, lung cancer screening, and perceived risk of lung cancer have not been widely studied in Malaysia. The primary objective of this study was to describe the factors affecting the willingness of high-risk current smokers and ex-smokers to undergo low-dose computed tomography (LDCT) screening for lung cancer.
Methods:
A prospective, cross-sectional questionnaire study was conducted in current smokers or ex-smokers aged between 55 and 80 years at three hospitals in Kota Kinabalu, Sabah, Malaysia. The questionnaire recorded the following parameters: perceived lung cancer risk; Prostate Lung Colon Ovarian Cancer 2012 risk prediction model excluding race and ethnicity predictor (PLCOm2012norace); demographic characteristics; psychosocial characteristics; and attitudes towards lung cancer and lung cancer screening.
Results:
A vast majority of the 95 respondents (94.7%) indicated their willingness to undergo screening. Stigma of lung cancer, low levels of knowledge about lung cancer symptoms, concerns about financial constraints, and a preference for traditional medication were still prevalent among the respondents, and they may represent potential barriers to lung cancer screening uptake. A desire to have an early diagnosis (odds ratio [OR], 11.33; 95% confidence interval [CI], 1.53 to 84.05; p=0.02), perceived time constraints (OR, 3.94; 95% CI, 1.32 to 11.73; p=0.01), and proximity of LDCT screening facilities (OR, 14.33; 95% CI, 1.84 to 111.4; p=0.01) had significantly higher odds of willingness to undergo screening.
Conclusion
Although high-risk current smokers and ex-smokers are likely to undergo screening for lung cancer, several psychosocial barriers persist. The results of this study may guide the policymakers and clinicians regarding the need to improve lung cancer awareness in our population.
