Fulltext A rare presentation of isolated carpal bone tuberculous osteomyelitis mimicking gouty arthritis

Abdul Hamid MF, Rajandiran SR, Yu-Lin AB, Sapuan J

Int J Mycobacteriol, 2020 8 31;9(3):325-328.

Tuberculosis (TB) is the most prevalent infectious disease in Southeast Asia. It causes both pulmonary and extrapulmonary diseases. TB of the wrist is rare and presents as osteomyelitis or tenosynovitis. We report a middle-aged male with carpal bone tuberculous osteomyelitis. He presented with left wrist pain initially treated as gouty arthritis. Within 2 weeks, he developed seropurulent discharge with osteomyelitic changes on imaging. He underwent debridement, and intraoperatively, there was destruction of most carpal bones. Histopathological examination revealed chronic granulomatous inflammation with abscess formation. Anti-TB medication was initiated, and he made a complete recovery with almost full range of wrist movement after 9 months of treatment. This case serves as a reminder that TB is a great mimicker, and a high index of suspicion is required to make a diagnosis of TB of the wrist. Early initiation of anti-TB is pivotal to prevent complications and deterioration of joint functions.
Fulltext Suture Granuloma 14 Years Following Partial Thyroidectomy Masquerading as Tuberculosis af The Sinus Tract

Suture granuloma rarely occurs after thyroid surgery using non-absorbable sutures. We report the case of a 63-year-old female with a chronic discharging sinus in the anterior neck region. She had a history of subtotal thyroidectomy at the age of 45. The sinus had been excised and was reported as granulomatous lesions suggestive of tuberculosis. She was treated with anti-tuberculous medications, but unfortunately, she developed side effects. Histopathological slides were re-evaluated, which showed evidence of foreign material under polarized light; hence, the diagnosis was revised to suture granuloma. In conclusion, although sinus tract discharges are commonly attributed to tuberculosis, physicians should consider suture granuloma if they encounter a patient who has undergone a surgical procedure in the past.
Fulltext Disseminated tuberculosis masquerading primary myelodysplastic syndrome

Shaharir SS, Tumian NR, Yu Lin AB, Abdul Wahid SF

Tuberculosis is notoriously known to be a great mimicker of other diseases and may cause various haematologic abnormalities, especially with marrow involvement. A 61-year-old man who presented with right empyema and pancytopenia was diagnosed to have disseminated tuberculosis supported by the presence of caseating granuloma with Langhan's giant cells in the marrow and demonstration of acid-fast bacilli in the pleural fluid. Trilineage dysplasia from marrow aspirate was initially attributed to be reactive to the infection. A cytogenetic study was repeated after he showed poor response to a year of anti-tuberculosis treatment. The underlying primary myelodysplastic syndrome was unmasked when his cytogenetics showed trisomy 8. This case report has demonstrated the various haematological manifestations of tuberculosis and highlighted the importance of cytogenetic study in differentiating between primary and secondary myelodysplastic marrow changes.

Liquid silicone (polydimethylsiloxane) is an inert material that is commonly used for cosmetic purpose. Silicone embolization syndrome (SES) can rapidly progress to pneumonitis as a consequence of the injection of nonmedical-grade liquid silicone. We describe a case of severe silicone pneumonitis complicated with acute respiratory distress syndrome and bilateral pneumothorax secondary to silicone gluteal augmentation. In this case report, we aim to discuss our experience and approach in managing an uncommon case of SES.
Fulltext Cluster Analysis Evaluating PM2.5, Occupation Risk and Mode of Transportation as Surrogates for Air-pollution and the Impact on Lung Cancer Diagnosis and 1-Year Mortality

Asian Pac J Cancer Prev, 2019 07 01;20(7):1959-1965.
PMID: 31350951 DOI: 10.31557/APJCP.2019.20.7.1959

Objective: Epidemiological studies have reported the close relationship between risk for lung cancers and air pollution
in particular, for non-smoking related lung cancers. However, most studies used residential address as proxies which may
not estimate accurately an individual’s air pollution exposure. Therefore, the aim of this study was to identify risk factors
such as occupation and mode of transportation associated with lung cancer diagnosis and death. Methods: Subjects
with lung cancer (n=514) were evaluated both by chart reviews for clinical data and interviews to determine residential
address for ten years, main occupation and main mode of transportation. Annual particulate matter with diameter size
less than 2.5 micrometre (PM2.5) concentration were calculated based on particulate matter with diameter size less than
10 micrometre (PM10) data recorded by Malaysian Department of Environment. Logistic regression analysis, cluster
analysis and the Cox regression analysis were performed to the studied variables. Results: This study concurred with
previous studies that lung adenocarcinoma were diagnosed in predominantly younger, female non-smokers compared
to the other types of lung cancers. Lung adenocarcinoma subjects had annual PM2.5 that was almost twice higher than
squamous cell carcinoma, small cell carcinoma and other histological subtypes (p=0.024). Independent of smoking,
the κ -means cluster analysis revealed two clusters in which the high risk cluster involves occupation risk with air
pollution of more than four hours per day, main transportation involving motorcycle and trucks and mean annual PM2.5
concentration of more than 30 based on residential address for more than ten years. The increased risk for the high-risk
cluster was more than five times for the diagnosis of lung adenocarcinoma (OR=5.69, 95% CI=3.14-7.21, p<0.001).
The hazard ratio for the high-risk cluster was 3.89 (95% CI=2.12-4.56, p=0.02) for lung adenocarcinoma mortality at
1 year. Conclusion: High-risk cluster including PM2.5, occupation risk and mode of transportation as surrogates for
air-pollution exposure was identified and highly associated with lung adenocarcinoma diagnosis and 1-year mortality.
Satisfaction and tolerability using virtual reality (VR) as adjunctive treatment during flexible bronchoscopy: a randomized control trial

Sooriyaghandan IV, Mohamad Jailaini MF, Nik Abeed NN, Ng BH, Yu-Lin AB, Shah SA, et al.

BMC Pulm Med, 2023 Jan 10;23(1):10.
PMID: 36627598 DOI: 10.1186/s12890-023-02304-y

BACKGROUND: Patient comfort during invasive and therapeutic procedures is important. The use of virtual reality (VR) devices during flexible bronchoscopy (FB) as a method of distraction to increase patient tolerability and improve satisfaction has not been investigated. We aim to assess the satisfaction and tolerability of participants undergoing FB with or without VR.
METHODS: This was a single-center, open-label study on patients undergoing bronchoscopy, randomized into the control and interventional (VR) groups. The control group received standard care during FB. The interventional group was given a VR device during FB showing nature videos with soothing instrumental music. Pain, breathlessness, and cough were evaluated using a 10 cm visual analogue scale administered before and after FB. Anxiety was assessed using the State-Trait Anxiety Inventory. Satisfaction questionnaire (5-point Likert scale) was given to participants post FB.
RESULTS: Eighty participants enrolled, 40 in each arm. Median (IQR) satisfaction score in the VR group was 5.0 (3.0-5.0), and in the control group was 4.0 (3.0-5.0); (p

BACKGROUND: The extent of short-acting Beta-2-agonist (β2-agonist) (SABA) use across Asian countries is not well documented. As part of the SABA use IN Asthma (SABINA) III study, we assessed SABA prescriptions and clinical outcomes in patients with asthma from Asia.
METHODS: This cross-sectional study recruited patients (aged ≥12 years) with asthma from 8 Asian countries. Data on disease characteristics and asthma treatments were collected using electronic case report forms. Patients were classified by practice type (primary or specialist care) and investigator-defined asthma severity (per Global Initiative for Asthma [GINA] 2017 recommendations). The association of SABA prescriptions with clinical outcomes was analyzed using multivariable regression models.
RESULTS: Overall, 3066 patients were analyzed, with a mean (standard deviation) age of 51.8 (16.7) years; of these patients, 2116 (69%) were female, 2517 (82.1%) had moderate-to-severe asthma and 2498 (81.5%) and 559 (18.2%) were treated in specialist and primary care, respectively. In total, 1423 (46.4%) patients had partly controlled/uncontrolled asthma, with 1149 (37.5%) patients experiencing ≥1 severe asthma exacerbation in the previous year. Overall, 800 (26.7%) patients were prescribed ≥3 SABA canisters in the previous year, which is regarded as overprescription and was associated with a significantly decreased odds of at least partly controlled asthma and increased incidence rates of severe exacerbations (P
