Traumatic pulmonary pseudocyst.

Blunt thoracic trauma manifests in various ways, depending on the structures injured and type of injury. Commonly manifested as parenchymal contusion, at times, pseudacavitation may also been seen on the chest X ray. They are to be differentiated from other causes of pulmonary cavitations which are often done based on history. The so called pulmonary pseudo cysts usually have a benign course and needs only observation.

Analysis of thyroid function tests in patients of multidrug resistance tuberculosis undergoing treatment

Sir, Emergence of multidrug resistance tuberculosis is now a health problem faced by most of the developing countries as well as developed countries across the globe. MDR-TB is defi ned as resistance to isoniazid and rifampicin with or without resistance to other anti-TB drugs.[1] The prevalence of MDR-TB is 1–3% in new cases and around 12–17% in retreatment cases or failure cases.[2,3] The treatment of these cases includes a regimen for 24 month duration including initial 6–9 months of intensive phase. Drugs used for treatment (beta-blocker) were used. Phentolamine countered the immobility duration reducing action of tramadol to a greater extent than propranolol. Thus the antidepressant activity of tramadol may be mediated through its interactions with the noradrenergic system as evidenced by the results of our study. Similar observations were noted in the earlier literature.[5] Although the antidepressant-like effect of tramadol is explained by its ability to modulate opioid receptors and noradrenergic system, the serotenergic system and the dopaminergic system might also account for its action as these are also substrates for monoaminergic transporter.[5,6] Role of these monoaminergic systems was not evaluated in this study which needs to be investigated in future studies.

Non-small cell lung carcinoma presenting as carcinomatous meningitis

Meningeal carcinomatosis is a diffuse infiltration of leptomeninges and sub arachnoid space by malignant cells metastasizing from systemic cancer. Primary bronchogenic carcinoma presenting as carcinomatous meningitis is a very rare occurrence in clinical practice, often occurring during the treatment course of the underlying malignancy. We present this rare presentation in a young non-smoker male.

Myelomatous pleural effusion ‐ Thoracoscopic evaluation of a rare entity

Multiple myeloma is a malignant neoplasm of plasma cell origin that mainly affects bone marrow and skeletal system, producing large amount of light chain immunoglobulins. Pleural involvement in multiple myeloma is a rare complication which carries very poor prognosis. We report a case of multiple myeloma who presented with recurrent pleural effusion that was evaluated by means of thoracoscopy.

Carcinoma breast related metastatic pleural effusion: A thoracoscopic approach

Background: Pleural effusions are common and devastating complication of advanced malignancies. Lung and breast cancers cause approximately 75% of all malignant pleural effusions. Pleural effusions associated with carcinoma breast (either malignant or paramalignant) pose diagnostic and therapeutic dilemmas for the treating chest physician. Materials and Methods: In a prospective study of analysis of unexplained pleural effusions, we performed medical thoracoscopy in 9 cases of carcinoma breast between April 2011 and September 2014. All the relevant clinical and paraclinical were collected and analyzed. Results: Sole pleural effusion was the most common radiological finding. This article reviews 9 cases of carcinoma breast patients, who had developed recurrent lymphocytic exudative pleural effusion, within a year of diagnosis. Thoracoscopy was diagnostic in all 9 cases with a histological diagnosis of metastatic carcinoma arising from the breast. Surprisingly malignant cells were negative in pleural fluid of all cases on three consecutive occasions. Conclusion: Carcinoma breast related pleural effusion is a common condition encountered in respiratory medicine and oncology. Thoracoscopic guided pleural biopsy is an effective and safe technique in patients with undiagnosed pleural effusion. It not only gives an accurate diagnosis but also gives a high degree of relationship between thoracoscopic appearance and primary disease or tumor classification.

Diagnostic evaluation of mediastinal lesions: Analysis of 144 cases

Background: Mediastinum is a “Pandoras box” with many neoplastic and nonneoplastic lesions. The purpose of this study was to analyze our institutional experience of mediastinal lesions on fine-needle aspiration cytology (FNAC) and/or biopsy. Materials and Methods: This study was an analysis of 144 patients who had undergone ultrasound-guided FNAC and/or core biopsy for mediastinal lesions. Results: A total of 144 cases of suspected mediastinal masses were seen, and in 139 cases, tissue diagnosis was attempted. Out of 139 cases, 93 cases were neoplastic in nature (67%), 32 were nonneoplastic (23%), and 14 remained inconclusive (10%). Among neoplastic mediastinal lesions, metastatic carcinoma (37.4%) was the most common neoplastic lesion, followed by non-Hodgkins lymphoma (12.2%), Hodgkins lymphoma (7.1%), thymic lesions (3.5%), etc. Among nonneoplastic conditions, tuberculosis was the most common lesion (20.1%). An accurate tissue diagnosis was made in 89.9% cases by FNAC or core biopsy of mediastinal lesions in this study. Procedure-related mortality was nil. Complications were mostly minor and included chest pain in 24.5%, small pneumothorax in 13.6% requiring closed tube thoracostomy in 1.4%, and scanty hemoptysis in 9.3% cases. Conclusion: Neoplastic mediastinal lesions are more common than nonneoplastic lesions, with metastatic carcinoma being the most common cause followed by tuberculosis. A wide variety of lesions observed in this study stress on the importance of cytohistological diagnosis in all cases of mediastinal lesions for the final diagnosis and management planning. A guided FNAC or core biopsy is still accurate, well tolerated, and devoid of major complications.

Thoracoscopic evaluation of 129 cases having undiagnosed exudative pleural effusions.

Background: Medical thoracoscopy is a minimally invasive procedure used in diagnostic and therapeutic applications for pleural diseases. In this study, we describe our experience in the outcome and analysis of thoracoscopy in undiagnosed pleural effusion presenting to our center. Materials and Methods: This is a prospective study conducted over last 2 years. We performed thoracoscopy in 129 cases of undiagnosed exudative pleural effusions using rigid thoracoscope. Clinical, radiological, cyto and histopathological data of the patients were collected prospectively and analyzed. Results: The overall diagnostic yield of thoracoscopic pleural biopsy was 110/129 (85.2%) in patients with undiagnosed pleural effusion, and 19/129 (14.8%) patients remained unexplained. Histopathological diagnosis confirmed malignancy in 66.4% patients (both primary and metastatic pleural carcinoma), tuberculosis in 28.2%, others including parapneumonic effusion in 4 cases followed by multiple myeloma, lupus pleuritis, and pulmonary langerhans cell histiocytosis in one case each. Procedure-related mortality was nil. Minor complications related to the procedure include hemorrhage, subcutaneous emphysema, etc. Conclusion: Thoracoscopy is relatively a safe and well-tolerated procedure with high diagnostic accuracy in undiagnosed pleural effusions, decreasing the need of formal diagnostic thoracotomy. Every chest physician must, therefore, consider this procedure to decrease the time lag in achieving the final diagnosis and to initiate the treatment as early as possible.

Hepatitis B infection and vaccination: Knowledge, Attitude and Practices among primary health care personnel in Lucknow -

Background: Hepatitis B is a major global health problem and one of the most serious type of viral hepatitis, but it can be prevented with strategies like safe and effective vaccination, increasing awareness and by adhering to universal precautions. Objective: The present study aimed to assess the knowledge attitude and practice concerning Hepatitis B infection among the health care personnel in selected Primary Health Care Centres in Lucknow. Materials and methods: Cross-Sectional study was conducted among health care personnel working at the Primary Health Centres in Lucknow. A total of 89 health care personnel comprising of medical officers, staff nurses, laboratory technicians, pharmacists including class IV workers present on the day of data collection were included in the study and interviewed using pretested questionnaire. Descriptive summary using frequencies, proportions and percentages were used to present study results. Result: Majority (93.4%) of the medical officers were aware about type of hepatitis, while knowledge regarding same was comparatively low among staff nurses, paramedical staff and class IV workers (20.0%, 21.8% and 4.5% respectively). Knowledge about symptoms of hepatitis B was found minimal (9.1%) among class IV workers and paramedical staff (18.7%) as compared to doctors (80.0%) and staff nurse (35.0%). Only 13.6% of class IV worker had concern to report each and every case of needle stick injury. Practice to strictly follow of universal precautions and biomedical waste management guidelines was found to be least (9.1% and 18.1% respectively) among class IV workers. Conclusion: The study revealed sub-optimal KAP in concern to several aspects of Hepatitis B infection among primary healthcare personnel. Therefore insights a need to increase the knowledge level as well ideal behaviour in practice through quality training and proper orientation programmes for health care personnel to prevent the spread of hepatitis B infection.

A rare case of pulmonary cysticercosis manifesting as lung cavity with pleural effusion.

Isolated pulmonary cysticercosis is extremely rare manifestation of a rather common disease which is distributed worldwide. Most common sites which provide perfect nourishment for the growth of cysticercosis are muscle and brain followed by eye. Pulmonary involvement in cysticercosis is very rare and if at all present, then ill-defined nodular shadows distributed throughout the lung is the usual radiological presentation. No case of cysticercosis presenting as lung cavity with pleural effusion has been reported so far in literature. We came across a rarest presentation of cysticercosis as cavity in the lung with effusion. After nullifying all the differential diagnosis of cavitary lung lesions, a diagnosis of pulmonary cysticercosis was made by histopathological examination of the lung cavity aspirate and enzyme linked immunosorbent assay (ELISA) for cysticercosis. Case was successfully treated with albendazole (15mg/kg) with steroid cover.

Peripheral neuropathy in Chronic Obstructive Airway Disease

Peripheral neuropathy in COPD has received scanty attention despite the fact that very often clinicians come across COPD patients having clinical features suggestive of peripheral neuropathy while this comorbidity is often overlooked & considered a separate entity. A number of studies have now confirmed the association of COPD and peripheral neuropathy with hypoxaemia being a dominant etiopathogenic factor among others. We report a case a demyelinating polyradiculopathy in a patient with COPD along with a brief review of literature.
