RESUMEN
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 < 0.001). Breathlessness, cough, and anxiety post FB were significantly less severe in the interventional group (p = 0.042, p = 0.001, p < 0.001), but the pain was not significantly different (p = 0.290). CONCLUSION: VR used during FB led to better participants' satisfaction and tolerability (breathlessness and cough). There was a significantly lower anxiety score in the VR group.

BACKGROUND: Current management of poorly draining complex effusions favours less invasive image-guided placement of smaller tubes and adjunctive intrapleural fibrinolysis therapy (IPFT). In MIST-2 trial, intrapleural 10 mg alteplase (t-PA) with 5 mg of pulmozyme (DNase) twice daily for 72 h were used. We aimed to assess the effectiveness and safety of a modified regimen 16 mg t-PA with 5 mg of DNase administered over 24 h in the management of complex pleural infection. METHODS: This was a single centre, prospective study involving patients with poorly drained pleural infection. Primary outcome was the change of pleural opacity on chest radiograph at day 7 compared to baseline. Secondary outcomes include volume of fluid drained, inflammatory markers improvement, surgical referral, length of hospitalisation, and adverse events. RESULTS: Thirty patients were recruited. Majority, 27 (90%) patients were successfully treated. Improvement of pleural opacity on chest radiograph was observed from 36.9% [Interquartile range (IQR 21.8-54.9%)] to 18.1% (IQR 8.8-32.7%) of hemithorax (P < 0.05). T-PA/DNase increased fluid drainage from median of 45 mls (IQR 0-100) 24 h prior to intrapleural treatment to 1442 mls (IQR 905-2360) after 72 h; (P < 0.05) and reduction of C-reactive protein (P < 0.05). Pain requiring escalation of analgesia affected 20% patients and 9.9% experienced major adverse events. None required surgical intervention. CONCLUSION: This study suggests that a modified regimen 16 mg t-PA with 5 mg DNase can be safe and effective for patients with poorly drained complex pleural infection. Trial registration The study was registered retrospectively on 07/06/2021 with ClinicalTrials number NCT04915586 ( https://clinicaltrials.gov/ct2/show/NCT04915586 ).

BACKGROUND: Intrapleural fibrinolytic therapy (IPFT) is one of the treatment options for complex pleural effusion. In this study, the IPFT agent used was alteplase, a tissue plasminogen activator (t-PA). This study aims to determine the difference in the outcome of patients with complex pleural effusion between IPFT and surgery in terms of radiological improvement, inflammatory parameters, length of stay, and post-intervention complications. METHODS: A retrospective review of patients with complex pleural effusion treated at Universiti Kebangsaan Malaysia Medical Center from January 2012 to August 2020 was performed. Patient demographics, chest imaging, drainage chart, inflammatory parameters, length of hospital stay, and post-intervention and outcome were analyzed. RESULTS: Fifty-eight patients were identified (surgical intervention, n = 18; 31% and IPFT, n = 40, 69%). The mean age was 51.7 ± 18.2 years. Indication for surgical intervention was pleural infection (n = 18; 100%), and MPE (n = 0). Indications for IPFT was pleural infection (n = 30; 75%) and MPE (n = 10; 25%). The dosages of t-PA were one to five doses of 2-50 mg. The baseline chest radiograph in the IPFT group was worse than in the surgical intervention group. (119.96 ± 56.05 vs. 78.19 ± 55.6; p = 0.029) At week 1, the radiological success rate for IPFT and surgical intervention were 27% and 20%, respectively, and at weeks 4-8, the success rate was 56% and 80% respectively. IPFT was associated with lesser complications; fever (17.5%), chest pain (10%), and non-life-threatening bleeding (5%). CONCLUSION: IPFT was comparable to surgery in radiological outcome, inflammatory parameters, and length of stay with lesser reported complications.

Surgical evacuation has long been the standard treatment for hemothorax. However, some patients are not suitable candidates for surgery. Intrapleural fibrinolytic therapy (IPFT) has recently emerged as an effective alternative for managing retained hemothorax. This case report describes two patients with retained hemothorax who were unfit for surgery and were successfully treated with IPFT at our centre. Both patients were deemed unsuitable for surgery due to comorbidities and their overall functional status. They received three cycles of IPFT, each consisting of 2.5 mg of alteplase. This treatment effectively evacuated the retained hemothorax, achieving complete radiological resolution without immediate or delayed complications up to 3 months post-discharge.
RESUMEN
The treatment for empyema thoracis has been evolving over the years, including the usage of intrapleural fibrinolytic therapy (IPFT), for example, alteplase with intrapleural deoxyribonuclease (DNase) to enhance the drainage of pleural effusion. Here, we report two cases of thoracic empyema that were successfully treated with intrapleural saline irrigation and intrapleural tyloxapol apart from parenteral antibiotics as the pillar of the treatment. Both patients averted surgical procedure (decortication) and were discharged well. Upon follow-up, both cases showed clinical cure, biochemical recovery, and radiological improvement, indicating a good treatment outcome. This is the first reported cases on combination of saline irrigation with tyloxapol as alternative treatment for pleural infection.
RESUMEN
A 37-year-old woman, 25 weeks pregnant, experienced sudden massive hemoptysis. She had a background history of systemic lupus erythematosus (SLE) and past pulmonary tuberculosis (PTB). Emergency intubation was necessary, and bronchoscopy revealed blood pooling in both main bronchi, with active bleeding from the right upper lobe bronchus. Urgent computed tomography (CT) angiography of the bronchial artery identified a bleeding source and was successfully embolized. Antifungal and anti-tuberculous therapy was initiated based on bronchoalveolar lavage results. Despite initial improvement, hemoptysis recurred after the third week, leading to repeat embolization, followed by a caesarean section and right upper lobectomy. Both mother and baby survived, remaining well at a 6-week follow-up, emphasizing the complexities of managing recurrent hemoptysis during pregnancy and potential drug interactions.
RESUMEN
Managing a complicated pleural infection related to postsurgery can pose a clinical challenge, especially when initial interventions such as intercostal chest drain and antibiotics prove ineffective. We describe a man in his mid-60s who developed a recurrence of exudative pleural effusion caused by an oesophageal leak following laparoscopic total gastrectomy with Roux-y oesophagojejunostomy for gastric adenocarcinoma. Surgical repairs and oesophageal stenting were performed to address the oesophageal leak. Despite attempts at intercostal chest tube drainage, ultrasonography-guided targeted drainage of the locule and antibiotics, he did not show any improvement. He was unfit for surgical decortication. Due to the risk of bleeding, we chose a modified dose of intrapleural alteplase 5 mg and DNase 5 mg at 12-hour intervals for a total of three doses. This led to the complete resolution of the effusion. This case highlights that intrapleural tPA/DNase can be an adjunctive therapy in postsurgery-related complicated pleural effusion.

Chylothorax is a rare condition caused by pleural effusion resulting from thoracic duct injury. Recurrent chylothorax is often resistant to conservative treatment and presents a clinical conundrum in its management. Here, we report a compelling case of recurrent chylothorax that persisted despite the administration of total parenteral nutrition, octreotide and thoracic duct embolisation. The patient eventually required thoracic duct ligation and talc pleurodesis, which resulted in the resolution of the effusion. Our case is an illustrative example of the effective multidisciplinary management of recurrent bilateral idiopathic chylothorax.

We report a 35-year-old woman who presented with dyspnoea and chest pain for 1 week. High-resolution computed tomography (HRCT) thorax revealed bilateral pneumothoraces with diffuse lung cysts. Bilateral intercostal chest tubes were inserted, and there was a persistent air leak (PAL) bilaterally. We performed an autologous blood patch pleurodesis (ABPP) for the left PAL. For the right PAL, she underwent a successful right video-assisted thoracic (VATS) surgery, wedge biopsy, and surgical pleurodesis. Histopathology examination confirmed the diagnosis of lymphangioleiomyomatosis (LAM). The left pneumothorax recurred. An indwelling pleural catheter (Rocket® IPC™; Rocket Medical plc; WASHINGTON) was inserted and the patient was discharged after 1 day with an atrium pneumostat (Pneumostat™; Atrium Medical Corporation, Hudson, NH, USA) chest drain valve. The patient was initiated on Sirolimus 2 mg daily. The left PAL resolved at 6 weeks. This case highlights the benefit of IPC with an ambulatory pneumothorax device in a patient with LAM with PAL.
RESUMEN
Before the era of COVID-19 pandemic, organizing pneumonia (OP) is often underdiagnosed while tuberculosis (TB) is overdiagnosed especially in an endemic area. We report two patients with cryptogenic OP mimicking TB. First, a 56-year-old lady with right upper lobe air space opacity and, second, a 37-year-old lady with left upper lobe cavitary lesion. They were treated empirically for pulmonary TB as they had chronic cough with typical chest imaging findings. As there were no improvements despite anti-TB and investigations for TB were negative, they underwent image-guided biopsy which confirmed OP. Both patients received 6 months of corticosteroids therapy and made complete recovery. These cases highlight the rare presentation of OP and serves as a reminder that patients tested negative for TB, despite typical history and chest imaging findings, warrant further investigations as many diseases may mimic TB and vice versa.
RESUMEN
Hydrofluorocarbon (HFC) pneumonitis is an uncommon cause of inhalation injury. HFCs are a group of chemicals predominantly used for refrigeration and cooling. A 19-year-old air-conditioning technician developed acute onset of dyspnoea and chest tightness while servicing an air conditioner in a confined space. We diagnosed him with HFC pneumonitis based on the history of exposure and the high-resolution computed tomography (HRCT) thorax findings. He was treated with steroids and supportive oxygen therapy. He recovered fully after 5 days of hospitalization and was discharged. Review at 2 weeks in the outpatient setting showed significant radiological improvement on HRCT thorax.
RESUMEN
Tuberculous pleurisy is extra-pulmonary tuberculosis caused by Mycobacterium tuberculosis (MTB), which is one of the main cause of pleural effusions in developing countries. Intercostal chest catheter is useful for drainage of infected pleural fluid and facilitates sepsis control. However, management might be challenging in complex tuberculous pleural effusion as the septations within the effusion hinder pleural drainage. Intrapleural fibrinolysis therapy improved infected fluid drainage and septic parameter in parapneumonic effusions; however, there seems to be little data on its use in tuberculous pleurisy. In our case series of seven patients with complex tuberculous pleurisy, the use of intrapleural alteplase and deoxyribonuclease (DNase) facilitated fluid drainage which resulted in clinical and radiological improvement. These medications should not be confined to bacterial aetiology only as our case series highlights that in complex tuberculous pleurisy, intrapleural alteplase and DNase may be used as an adjunctive treatment which are proven to be successful and safe.
RESUMEN
Pleural infection is an important clinical problem with significant morbidity. In poorly draining complex pleural effusions, the current management favours a less invasive image-guided placement of smaller bore catheters and adjunctive intrapleural fibrinolysis therapy (IPFT). We describe our experience of using IPFT in three patients with different bleeding risks with complex pleural effusions. The first was a 30-year-old with transfusion-dependent ß-thalassemia with haemoglobin of 7.8 g/dL; second was an 87-year-old on dabigatran with haemoglobin of 10 g/dL; and the third was an 80-year-old with diffuse large B-cell lymphoma with haemoglobin of 8.6 g/dL. All three patients received three doses of alteplase and deoxyribonuclease (DNase) without any adverse effects of bleeding and had resolution of the effusion. This case series is an addition to the current literature on the safety of IPFT and we highlight the use of IPFT in patients with low baseline haemoglobin and on anticoagulation therapy.
RESUMEN
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.

Indwelling pleural catheter (IPC) is a useful tool for refractory malignant pleural effusions (MPEs). It allows palliation by intermittent symptomatic relief of the effusion and improves quality of life. Its use in benign pleural effusions comes mainly from retrospective studies, case series, and case reports. Lupus effusion is common, causes minimal symptoms, and usually responds to either steroid therapy or immunosuppressants. Refractory lupus effusion is less common and treatment may require invasive surgical pleurectomy. We describe a 52-year-old woman whose first presentation of systemic lupus erythematosus (SLE) was a pleural effusion refractory to steroids and immunosuppressants. She successfully achieved spontaneous pleurodesis with intermittent IPC drainage at three months.
RESUMEN
Chylothorax is an uncommon cause of pleural effusion. Recurrent chylous effusions are often resistant to conservative treatment and many need surgical intervention. We report a 69-year-old woman with refractory idiopathic chylothorax resistant to medium-chain triglyceride diet and intermittent thoracentesis. Lymphangiography and lymphoscintigraphy failed to identify the site of leakage. We initiated continuous positive airway pressure (CPAP) 12 h before and 48 hours after talc pleurodesis. Chest drain was removed at day 3 and she was discharged at day 5. To our knowledge, this is the first case of successful resolution of idiopathic refractory chylothorax with CPAP ventilation used in tandem with talc pleurodesis.
RESUMEN
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was declared a pandemic on 11 March 2020. We have since seen its fast spread worldwide. A likely contributing factor was the lack of symptoms of some of the carriers, making them unaware of their risk of spreading to other more vulnerable individuals. The other important finding has been the reported cases of infectivity despite lack of symptoms. We describe the SARS-CoV-2 pneumonia patterns in asymptomatic individuals. The common computed tomography (CT) thorax patterns found are peripheral ground-glass opacification (GGO) with upper or lower lobe predominance. We believe screening for 2019-novel coronavirus (COVID-19) in high-risk individuals may help identify the patients needing longer follow-up.
RESUMEN
Background: The effect of circadian disruption on the bio-psychological clock system has been widely studied. However, the mechanism and the association of circadian rhythm disruption with mental health and physiological responses are still unclear. Therefore, this study was conducted to investigate the effects of circadian rhythm disruption on mental health and physiological responses among shift workers and the general population. Methods: A total of 42 subjects participated in this quasi-experimental study. Participants were divided into a group of shift workers (n = 20) and a general population group (n = 22). Polysomnography tests, blood tests (cortisol, triglycerides and glucose), and psychological tests (Abbreviated Profile of Mood States, General Health Questionnaire-28, Working Memory and Processing Speed Indexes of the Wechsler Adult Intelligent Scale (WAIS-IV) were used to examine the effects of circadian rhythm disruption. Results: The results showed a significant relationship between circadian rhythm disruption and mood (r = 0.305, p < 0.05). The findings of this study also indicated that there was a significant effect of circadian rhythm disruption on mood (F(2,40) = 8.89, p < 0.001, η2 =0.182), processing speed (F(2,40) = 9.17, p < 0.001, η2 = 0.186) and working memory (F(2,40) = 4.963, p < 0.01, η2 = 0.11) in shift workers and the general population. Conclusions: Our findings showed that circadian rhythm disruption affects mood and cognitive performance, but it does not significantly affect psychological wellbeing and physiological responses. Future studies are warranted to examine moderator and mediator variables that could influence the circadian rhythm disruption.

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.
RESUMEN
This case series reviews two cases of elderly patients who presented with fever, cough and shortness of breath. Clinical examinations and initial chest radiographs confirmed unilateral pleural effusion. Thoracenteses were consistent with exudative pleural effusion. We commenced intravenous antibiotics treating for parapneumonic effusions. The first case showed persistent effusion despite drainage, and the second case had a little aspirate from pleural tapping. Subsequent ultrasound of the thorax showed multiloculated effusions. We made the decisions for intrapleural fibrinolytic therapy using low-dose alteplase 2.5 mg each time, in view of the elderly patient as sacrosanct for risk of bleeding. Furthermore, DNase was not used, as it is not yet available in our setting. Both of our patients had good clinical and radiological outcomes, without the need for surgical interventions.
