Meigs syndrome presenting with recurrent unilateral pleural effusion.

Pelvic tumours are a rare cause of pleural effusion. We describe an approach to a case of Meigs syndrome with recurrent unilateral pleural effusion. A woman in her 60s' presented with recurrent right-sided pleural effusion, leading to cough and shortness of breath. Thoracentesis yielded exudative pleural fluid with cytology negative for malignancy. Pleuroscopy revealed inflamed pleura, and pleural biopsy was consistent with inflammatory changes. The patient's cancer antigen 125 level was elevated at 256 U/mL. Given the high suspicion of malignancy, a computed tomography scan of the chest, abdomen, and pelvis was performed and revealed ascites and a large left ovarian and uterine mass. The patient underwent a total abdominal hysterectomy and bilateral salphingo oophorectomy after experiencing three additional episodes of pleural effusion. Histological examination revealed the left ovarian mass to be a cellular fibroma and the uterine masses to be leiomyomata. Following the operation, there was no recurrence of pleural effusion.

The benefit of indwelling pleural catheter with ambulatory pneumothorax device and autologous blood patch pleurodesis in lymphangioleiomyomatosis with persistent air leak.

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.

Evaluating the Optimal Operating Table Height for ProSeal-LMA™ Insertion.

Introduction: ProSeal-Laryngeal Mask Airway™ (P-LMA™) is one of the commonly used laryngeal mask airways. Despite the proper insertion technique, suboptimal positioning and airway morbidity still occurs. This study explored the possibility of the operating table height position affecting successful P-LMA™ placement. Methods: A total of 138 patients aged between 18 and 65 years old with the American Society of Anesthesiologists (ASA) I or II status, who required general anaesthesia and had no contraindication towards the use of P-LMA™, were recruited. They were randomly positioned into three anatomical landmarks, which were umbilicus, lowest rib margin, and xiphoid. P-LMA™ was inserted following muscle paralysis, and the first successful placement was evaluated using positional and performance tests. Duration, ease of P-LMA™ insertion, and airway complications were compared. Results: Demographic and airway features were comparable among all groups. The P-LMA™ placement success rate improved when the table height was positioned at the lowest rib margin (p=0.002). All three positions were comparable in terms of duration, ease of insertion, and airway morbidities. Conclusion: The lowest rib margin anatomical landmark can be used as a guide in achieving the optimal operating table height for successful P-LMA™ placement.

Indwelling pleural catheter for malignant pleural effusion with persistent air leak.

Malignant pleural effusion with persistent air leak (PAL) is a rare manifestation of lung malignancy. We present a woman in her 50s with postpleuroscopy PAL. Pleural biopsy confirmed adenocarcinoma with detection of epidermal growth factor receptor mutation in exon 19. An indwelling pleural catheter (IPC) was inserted and connected to an Atrium Express Mini ambulatory drain. This procedure reduced the length of hospital stay. Autopleurodesis with resolution of PAL occurred at week 3 of IPC insertion.

Prevention of Shivering Post Subarachnoid Block: Comparison between Different Doses of Intravenous Magnesium Sulphate.

Background and Objectives: Shivering is a common complication of subarachnoid block (SAB). Magnesium sulphate has been proven to be effective in preventing shivering. The aim of this study was to compare the effectiveness and adverse effects in hemodynamic parameters between 50 mg/kg and 30 mg/kg of intravenous magnesium sulphate for prevention of shivering post-subarachnoid block. Materials and Methods: Eighty-six patients scheduled for surgery under SAB, aged between 18 to 65 years old with American Society of Anesthesiologists physical status I and II were randomised into two groups. Group A received a bolus of 50 mg/kg, while Group B received 30 mg/kg of intravenous magnesium sulphate, given over a 20 min duration following SAB. Shivering grade was recorded intraoperatively according to the Crossley and Mahajan shivering scale. Mean arterial pressure (MAP), heart rate, tympanic temperature, oxygen saturation and the use of vasopressors were recorded. Results: Forty-five percent of patients in Group A and 20% of patients in Group B did not exhibit shivering (p-value < 0.01). High-grade shivering was observed in 12.5% in Group A and 40% in Group B, respectively (p-value 0.02). The MAP trend was lower in Group B (p-value < 0.01), but the incidence of hypotension was not significant in both groups. The use of vasopressors was also similar between groups. Group B showed a lower oxygen saturation trend (p-value 0.04). The trends of heart rate and tympanic temperature were not significant in both groups. No patients had episodes of bradycardia or oxygen desaturation. Conclusions: In this study, intravenous magnesium sulphate 50 mg/kg is the lowest effective dose for prevention and treatment of high-grade shivering post-SAB without significant hemodynamic adverse events.

Validation of Malay Language Translated Questionnaire on Adult Intensive Care Unit Nurses’ Perception and Involvement in End-of-life Care

@#Introduction: The study’s objective was to validate a Malay language translated questionnaire on end-of-life care to be used among nurses practicing in critical care areas. Methods: The English language questionnaire underwent forward and backward translations by four experts. The translated Malay language questionnaire was pilot tested on 30 subjects and revised accordingly. The validation of the revised questionnaire was carried out on 250 nurses. The reliability of the translated questionnaire was checked. Cronbach alpha value of at least 0.70 suggests adequate internal consistency. The validity of the questionnaire was explored using Confirmatory Factor Analysis (CFA) and model fit tests were run to achieve fit test specific cut off values. The CFAs were run repeatedly with iterative item reductions until acceptable goodness of fit for the model was achieved. Results: All domains of the translated questionnaire showed reasonable to excellent reliability (Cronbach Alpha 0.687 to 0.922). Multiple CFAs were run and 13 out of 46 items were excluded, and the final model fit improved substantially with the indices were within the acceptable threshold of good or reasonably fit, cut off values are in brackets [Chi-Square statistics 1.635 (≤ 2.0), Root Mean Square Error of Approximation 0.050 (< 0.05), Standardised Root Mean Square Residual 0.059 (≤ 0.08), Comparative Fit Index 0.911 (0.90-0.94), Tucker Lewis Index 0.900 (0.90-0.94), Akaike Information Criteria 13024, Bayesian Information Criteria 13334]. Conclusion: The psychometric properties of the final model indicated the Malay language translated questionnaire is reliable and valid to investigate nurses’ perspective and involvement in end-of-life care.

An approach to develop clinical prediction rule for candidemia in critically ill patients: A retrospective observational study.

PURPOSE: Early detection of candidemia in critically ill patients is important for preemptive antifungal treatment. Our study aimed to identify the independent risk factors for the development of a new candidemia prediction score. METHODS: This single-centre retrospective observational study evaluated 2479 intensive care unit (ICU) cases from January 2016 to December 2018. A total of 76 identified candidemia cases and 76 matched control cases were analyzed. The patients' demographic characteristics and illness severity were analyzed, and possible risk factors for candidemia were investigated. RESULTS: Multivariate logistic regression analysis identified renal replacement therapy (RRT) (odds ratio [OR]: 52.83; 95% confidence interval [CI]: 7.82-356.92; P < 0.0001), multifocal Candida colonization (OR: 23.55; 95% CI: 4.23-131.05; P < 0.0001), parenteral nutrition (PN) (OR: 63.67; 95% CI: 4.56-889.77; P = 0.002), and acute kidney injury (AKI) (OR: 7.67; 95% CI: 1.24-47.30; P = 0.028) as independent risk factors. A new prediction score with a cut-off value of 5.0 (80.3% sensitivity and 77.3% specificity) was formulated from the logit model equation. CONCLUSIONS: Renal replacement therapy, AKI, PN, and multifocal Candida colonization were the independent risk factors for the new candidemia prediction score with high discriminatory performance and predictive accuracy.

Cryodebulking of endobronchial hamartoma via fibreoptic bronchoscopy and literature review.

Endobronchial hamartoma is a rare tumour. We report a 65-year-old woman with a history of recurrent pneumonia. Bronchoscopy revealed a 1 cm endobronchial mass obstructing the left upper lobe bronchus. Histopathological examination was consistent with a pulmonary hamartoma. This lesion was successfully debulked endoscopically with the use of a flexible cryoprobe without any complications. This case highlights both the importance of investigating recurrent pneumonia and the usefulness of endoscopic recanalisation in an obstructed segmental bronchus.

Indwelling pleural catheter and successful autopleurodesis of refractory inflammatory lupus effusion.

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.

Resolution of refractory chylothorax with a combination of talc pleurodesis and CPAP.

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.

What happens when we treat the "Typhoid Mary" of COVID-19.

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.
