PURPOSE
Tuberculosis is one of the dreadful infections and India contributes to substantial burden of TB cases globally. Though majority of cases are pulmonary, extra-pulmonary tuberculosis (EPTB) share significant burden, more in HIV-positive persons. Despite the striking burden, very few studies have been conducted in India and present study was undertaken to determine trends of EPTB at our tertiary care centre.
METHODS
This was a retrospective study conducted over a period of 4 years 3 months. Diagnosis of EPTB was based on suspected clinical features, with positive micobiological evidence with cartridge based nucleic acid amplification test (CBNAAT) with/without microscopy.
RESULTS
A total of 10,560 samples (pulmonary and extra-pulmonary) were received during the study period, of which 3,972 were extrapulmonary. Of these, a total of 18% were noted to be positive for EPTB. Trend of positivity revealed highest burden in in 2018 and a decline was noted over the years, however, rise in cases was noted in 2022. Pleural, meningitis, musculoskeletal, peritoneal and pericardial TB was more common in males, while lymphadenitis was more common in females (p value: <0.0001). Pleural TB (31%) was the most common presentation, followed by lymphadenitis. A gradual decline in lymphadenitis was noted with significantly increasing trend only for musculoskeletal TB. Rifampicin resistance was detected in 7.45% of positive samples, of which the maximum rate of resistance was noted in lymph node aspirates (11.11%), followed by musculoskeletal and pleural samples.
CONCLUSION
The present study showed a gradual decline in positivity of EPTB cases over the years. Younger productive age group with more propensity to transmit infection was the most commonly affected, with pleural TB as the most common presentation. Rare presentations of EPTB also contributed major share. Higher rates of resistance underline requisite to strengthen ongoing programs, to achieve the End TB strategy by 2025.

BMC Infectious Diseases Jun 2024Nocardia species can affect both immunocompetent and immunocompromised people. (Comparative Study)
Comparative Study
BACKGROUND
Nocardia species can affect both immunocompetent and immunocompromised people.
METHOD
This retrospective study, from 2009 to 2022, aims to compare the survival analyses of pulmonary nocardiosis in AIDS and non-AIDS patients in northeastern Thailand.
RESULTS
A total of 215 culture-confirmed cases of pulmonary nocardiosis: 97 with AIDS and 118 without AIDS. The median CD4 count of AIDS patients was 11 cells/µL (range: 1-198), and 33% had concurrent opportunistic infections. 63.6% of 118 non-AIDS patients received immunosuppressive medications, 28.8% had comorbidities, and 7.6% had no coexisting conditions. Disseminated nocardiosis and pleural effusion were more prevalent among AIDS patients, whereas non-AIDS patients revealed more shock and respiratory failure. One hundred-fifty patients underwent brain imaging; 15 (10%) had brain abscesses. Patients with pulmonary nocardiosis have overall 30-day and 1-year mortality rates of 38.5% (95% CI: 32.3%, 45.4%) and 52.1% (95% CI: 45.6%, 58.9%), respectively. The Cox survival analysis showed that AIDS patients with disseminated nocardiosis had a 7.93-fold (95% CI: 2.61-24.02, p < 0.001) increased risk of death within 30 days compared to non-AIDS patients when considering variables such as age, Charlson comorbidity index, concurrent opportunistic infections, duration of illness, shock, respiratory failure, multi-lobar pneumonia, lung abscesses, and combination antibiotic therapy. While AIDS and pulmonary nocardiosis had a tendency to die within 30 days (2.09 (95% CI, 0.74-5.87, p = 0.162)).
CONCLUSION
AIDS with pulmonary nocardiosis, particularly disseminated disease, is a serious opportunistic infection. Early diagnosis and empiric treatment with a multidrug regimen may be the most appropriate approach in a resource-limited setting.

The aim of this study is to delineate the distinctive high-resolution computed tomography features of pulmonary cryptococcosis in non-HIV-infected patients. This retrospective analysis encompasses high-resolution computed tomography scans from 58 patients with histologically confirmed pulmonary cryptococcosis, focusing on the diagnostic challenges and the factors that lead to misdiagnosis. Analysis of computed tomography scans from these patients indicated that nodular or mass-like presentations were evident in 32 cases (55.2%), consolidation presentations in 7 cases (12.1%), and mixed presentations in 19 cases (32.8%). Lesions were predominantly located in the lower lobes of the lungs (40 cases, 69.0%) and in peripheral zones (55 cases, 94.8%). Notable radiographic signs included the presence of the burr sign in 55 cases (94.8%), lobulation sign in 53 cases (91.4%), halo sign in 53 cases (91.4%), and air bronchogram in 46 cases (79.0%). Moreover, 24 cases (41.4%) exhibited necrosis or cavitation, mediastinal lymphadenopathy was noted in 6 cases (10.3%), and pleural effusion was present in 5 cases (8.6%). Lesions were devoid of calcification. Pulmonary cryptococcosis ought to be contemplated in the differential diagnosis when computed tomography imaging exhibits patterns including, but not limited to, lower lobe and peripheral distribution, a broad base abutting the pleura, clustered growth with a propensity for fusion, air bronchogram within lesions, and peripheral halo sign.

Outcomes of Tube Thoracostomies in COVID-19 Patients: A Retrospective Cohort Study in the University of the Philippines - Philippine General Hospital COVID-19 Referral Center.
OBJECTIVE
To describe the treatment outcomes of patients who underwent tube thoracostomy for pleural complications in patients with COVID-19 and determine the association between patient profile and treatment outcomes.
METHODS
A single-institution retrospective review of patients who underwent tube thoracostomy for complications of COVID-19 infection in the University of the Philippines - Philippine General Hospital (UP-PGH) from March 30, 2020, to March 31, 2021, was performed. These patients' demographic and clinical profiles were evaluated using median, frequencies, and percentages. The association between patient profile, and mortality and reintervention rates was assessed using univariable Cox proportional hazards regression analysis.
RESULTS
Thirty-four (34) of 3,397 patients (1.00%) admitted for COVID-19 pneumonia underwent tube thoracostomy. Of these, 34, 47.06% were male, 52.94% were female, the median age was 51.5 years old, 85.29% had comorbid conditions, and 29.41% had a previous or ongoing tuberculous infection. The most common indication for tube thoracostomy was pleural effusion (61.76%), followed by pneumothorax (29.41%), and pneumo-hydrothorax (8.82%). The mortality rate was 38.24%, and the reintervention rate was 14.71%. Intubated patients had 14.84 times higher mortality hazards than those on room air. For every unit increase in procalcitonin levels, the mortality hazards were increased by 1.06 times.
CONCLUSION
An increasing level of oxygen support on admission and a level of procalcitonin were directly related to mortality risk in COVID-19 patients who underwent tube thoracostomy for pleural complications. There is insufficient evidence to conclude that patient-related, COVID-19 pneumonia-related, and procedure-related factors included in this study were significantly associated with reintervention risk.

Comparative Study
The onset of the COVID-19 pandemic allowed physicians to gain experience in lung ultrasound (LUS) during the acute phase of the disease. However, limited data are available on LUS findings during the recovery phase. The aim of this study was to evaluate the utility of LUS to assess lung involvement in patients with post-COVID-19 syndrome. This study prospectively enrolled 72 patients who underwent paired LUS and chest CT scans (112 pairs including follow-up). The most frequent CT findings were ground glass opacities (83.3%), subpleural lines (72.2%), traction bronchiectasis (37.5%), and consolidations (31.9%). LUS revealed irregular pleural lines as a common abnormality initially (56.9%), along with subpleural consolidation >2.5 mm ≤10 mm (26.5%) and B-lines (26.5%). A strong correlation was found between LUS score, calculated by artificial intelligence percentage involvement in ground glass opacities described in CT (r = 0.702, < 0.05). LUS score was significantly higher in the group with fibrotic changes compared to the non-fibrotic group with a mean value of 19.4 ± 5.7 to 11 ± 6.6, respectively ( < 0.0001). LUS might be considered valuable for examining patients with persistent symptoms after recovering from COVID-19 pneumonia. Abnormalities identified through LUS align with CT scan findings; thus, LUS might potentially reduce the need for frequent chest CT examinations.

: Lung ultrasound (LUS) is a tool of growing interest in Rheumatoid Arthritis (RA) oligo- symptomatic ILD to avoid. : We aimed to evaluate (i) the prevalence of pleural (PLUS) and parenchymal (PAUS) abnormalities in LUS in the RA population and their possible correlation to biomarkers; (ii) the predictivity of gender, smoking habits, previous infections (past COVID-19 tuberculosis), and treatments; (iii) the differences in LUS between sexes. : We collected the data of 155 (15 early and 140 late) RA patients with mild respiratory symptoms, evaluating PLUS and PAUS, in fourteen lung areas and also summing the scores (LUS-T). : Only 13/155 (8.4%) were completely negative; LUS correlated to age (all parameters 0.0001), rheumatoid factor IgM (PLUS 0.0006, PAUS 0.02, LUS-T 0.001) and ACPA ( 0.001, 0.006, 0.001, respectively), and PLUS also correlated to IL6 ( 0.02). The male gender was predictive of all LUS evaluations ( 0.001, 0.05, 0.001, respectively), which were higher than in women ( 0.001, 0.01, 0.001, respectively). Other potential risk factors were independent, except biological treatments, which showed a low predictivity to PLUS ( < 0.05). We can conclude that LUS is a useful technique in RA low respiratory symptoms and correlates with age, the most important RA biomarkers, and male sex.

Hepatocellular carcinoma (HCC) stands as a significant contributor to cancer-related mortality globally. While the acute and often fatal manifestations of locally advanced HCC primarily present within the abdomen, it is crucial to recognize that the respiratory and circulatory systems can also fall victim due to the liver's unique anatomical position within the body. Here, we present the case of a 63-year-old male recently diagnosed with locally advanced HCC with vascular invasion. Shortly after receiving target therapy and focal radiotherapy, the patient developed repeated secondary infections and a persistent diaphragmatic defect. As the necrotic tissue invaded the pleural space, subsequent tumor-to-bronchial and tumor-to-cardiac fistulas emerged, resulting in an abnormal connection between the respiratory and cardiovascular systems, leading to massive air emboli in circulation. This report highlights the risk of supradiaphragmatic complications in HCC patients with post-treatment secondary infections, particularly in patients predisposed to developing diaphragmatic defects.

Multiple myeloma is a rare haematological malignancy characterised by the clonal proliferation of plasma cells within the bone marrow. Typical manifestations include bone pain, fatigue and monoclonal protein elevation in serum and urine. Less than 1% of cases develop myelomatous pleural effusion, a severe complication indicative of advanced disease and a very poor prognosis.Here, we present a case of a woman with a new diagnosis of multiple myeloma complicated by bilateral myelomatous pleural effusions as the initial presentation. This case underscores the diverse clinical spectrum of multiple myeloma, the significance of timely diagnosis and the threatening implications associated with myelomatous pleural effusions.

BACKGROUND
pneumonia is very rare in normal people. At present, there is a lack of clinical data on the clinical characteristics and diagnosis and treatment experience of patients with this type of infection. Our team had recently treated 7 cases of these patients. This study aims to comprehensively summarize and analyze the clinical characteristics and treatment methods of pneumonia, and to provide clinical evidence for the diagnosis and treatment of pneumonia.
METHODS
Clinical data were retrospectively collected from patients diagnosed with pneumonia through metagenomic next-generation sequencing (mNGS) at the Department of Pulmonary and Critical Care Medicine, Meizhou People's Hospital.
RESULTS
Seven patients with pneumonia reported a history of poultry exposure, experiencing fever alongside respiratory or digestive symptoms. Marked elevation of blood inflammation markers, accompanied by hypoproteinemia and liver damage, was observed. Chest CT scans revealed pneumonia and pleural effusion. was detected in blood or bronchoalveolar lavage fluid (BALF) through mNGS, often co-occurring with or other bacteria infections. Notably, Doxycycline demonstrated efficacy in treating
CONCLUSION
infection is a zoonotic disease, particularly among individuals with a history of poultry exposure, and mNGS emerges as a reliable diagnostic tool for its detection. infection manifests with systemic and lung inflammation, effectively addressed through Doxycycline therapy.

As the number of pacemaker insertions increases to manage numerous cardiac arrhythmias, the number of complications is also increasing as a result. More common complications such as infection and lead displacement are routinely discussed with patients before they undergo the procedure. However rare complications such as superior vena cava syndrome are not discussed during the consenting period. But they do occur, as seen in this case of a 69-year-old male. This fit and active man had a right-sided dual-chamber pacemaker inserted due to sinus node disease and presented 5 years later with symptoms suggestive of superior vena cava obstruction (SVCO). Despite anticoagulation and before surgical intervention could be performed, the patient developed a right-sided chylothorax which was drained. An autologous pericardial patch repair of the SVC and a thrombectomy of SVC clots was subsequently performed. This was only partially successful and the SVCO recurred. A low fatty chain diet was initiated to manage the chylothorax, which remains stable. This rare complication has left the patient with a small pleural effusion and chronic pleural thickening. They can still exercise with mild breathlessness. The management of such a complication, which requires the input of many specialists, is challenging and often does not completely resolve all symptoms. For this reason, superior vena cava obstruction should be considered as a risk during the consenting procedure for a pacemaker insertion.
