Systemic Therapy for Small-Cell Lung Cancer: ASCO-Ontario Health (Cancer Care Ontario) Guideline.

PURPOSE: To provide evidence-based recommendations to practicing clinicians on the management of patients with small-cell lung cancer. METHODS: An Expert Panel of medical oncology, thoracic surgery, radiation oncology, pulmonary, community oncology, research methodology, and advocacy experts were convened to conduct a literature search, which included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2022. Outcomes of interest included response rates, overall survival, disease-free survival or recurrence-free survival, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS: The literature search identified 95 relevant studies to inform the evidence base for this guideline. RECOMMENDATIONS: Evidence-based recommendations were developed to address systemic therapy options, timing of therapy, treatment in patients who are older or with poor performance status, role of biomarkers, and use of myeloid-supporting agents in patients with small-cell lung cancer.Additional information is available at www.asco.org/thoracic-cancer-guidelines.

Pleural Effusion: An Uncommon Manifestation of Hepatitis.

Hepatitis A virus infection is the commonest form of hepatitis in pediatric age group and common health problem in developing countries due to poor sanitation. The clinical spectrum of hepatitis A virus infection ranges from asymptomatic infection to fulminant hepatitis and the symptoms are primarily hepatobiliary or constitutional. Here, we present a case of 16 years old male who presented with complains of fever, vomiting, anorexia, right sided abdominal pain, shortness of breath and cough. On clinical examination, patient has hepatomegaly and decreased breath sounds on right sided mammary, infra- mammary and infra scapular region. Blood investigations showed aminotransferases while pleural effusion and ascites with thickened gall bladder were found in chest x-ray and abdominal ultrasonography respectively. In absence of others causes, pleural effusion can be a rare complication of hepatitis A. Thus, this complication should be kept in mind in endemic countries in clinically matching scenarios. Keywords: Acalculous cholecystitis; ascites; hepatitis A; pleural effusion.

A case report of secondary spontaneous pneumothorax in acute exacerbation of COPD managed with improvised chest tube drain.

Introduction: and importance: We reported a case of secondary spontaneous pneumothorax (SSP) in a 70-years-old male with acute exacerbation of COPD (AE COPD) managed with improvised chest tube drain (ICD). Case presentation: He presented with sudden onset breathlessness and oxygen saturation of 78%. With prolonged expiration on auscultation, he was treated as AE COPD with oxygen therapy, nebulization with albuterol/ipratropium, and injectable antibiotics and steroids. The patient was not improving with treatment on third day, and non-critical respiratory distress continued. Considering the alternative diagnosis, the chest X-ray was done which revealed right sided spontaneous pneumothorax and COPD. Due to his reluctancy to go to higher center for chest tube insertion during ongoing COVID-19 pandemic, we inserted ICD (intravenous set put in saline bottle) at our primary care. Following drainage, breathlessness improved and saturation increased. Then inpatient symptomatic treatment for COPD was continued for three more days. He was discharged on inhalers after fifth day and asked for follow up after 10 days. He came after 1 month and on repeat chest X-ray, his right sided pneumothorax resolved completely and COPD was in control with inhaled medications. There was no recurrence of pneumothorax in five months follow up. Clinical discussion: ICD is a safe, and an alternative option in resource limited setting. However, the guidelines recommend chest tube insertion as appropriate treatment. Conclusion: This would remind the physicians to anticipate the alternative possibility, and to re-examine those with AE COPD who are not improving as expected with oxygen and nebulization therapy.

Small Cell Lung Carcinoma with Pancoast Syndrome: A Case Report.

Small cell lung cancer mostly arises centrally in the large bronchi. The literature search revealed very limited cases of small cell lung cancer arising at the upper part of the pulmonary sulcus near the thoracic inlet as superior sulcus tumor and also manifesting with typical Pancoast syndrome. We report a case of a 71 years old male patient, presenting with features of Pancoast syndrome including Horner's syndrome with completed three cycles of chemotherapy resulting in partial response which concludes that small cell lung carcinoma has to be considered despite the clinical findings like pancoast syndrome.

Study of diagnostic utility of Xpert MTB/Rif test on pleural fluid in the evaluation of patients presenting with Pleural Tuberculosis in Nepal.

Introduction: Existing tests for the diagnosis of pleural tuberculosis (TB) have major limitations in terms of accuracy, time to diagnosis and drug resistance testing. A test which can diagnose pleural TB and detect resistance, like Xpert MTB/Rif, would be optimal for rapid diagnosis and treatment. Methods: A prospective observational study was done in a tertiary care hospital in Eastern Nepal. Fifty-one patients with clinic-radiologic suspicion of pleural TB were included. The results of pleural fluid Xpert MTB/Rif were compared with two Composite Reference Standards. Composite Reference Standard-1 consisted of positive pleural fluid smear, positive culture, positive histology of pleural biopsy, and positive sputum results. Composite Reference Standard-2 included those with Composite Reference Standard-1 and those with high ADA values (>40 U/l) with response to anti-tubercular treatment at 8 weeks of follow-up. Results: Thirty-six patients were diagnosed as Pleural TB. Nine fulfilled Composite Reference Standard-1. Pleural fluid Xpert MTB/Rif was positive in five cases with Composite Reference Standard-1 and nine cases with Composite Reference Standard-2. The sensitivity, specificity, positive predictive value and negative predictive value with reference to Composite Reference Standard-1 were 55.56%, 88.10%, 50%, and 90.24%, respectively. Using Composite Reference Standard-2 as reference, sensitivity, specificity, positive predictive value and negative predictive value were 25%, 93.33%, 90%, and 34.15%, respectively. Two cases were diagnosed Xpert Rif resistant on pleural fluid. Conclusion: Due to low sensitivity, the Xpert MTB/Rif test cannot be recommended as initial test of diagnosis in a high prevalence setting. At the same time its clinical utility lies in testing of patients suspected to have drug-resistant pleural tuberculosis.

Success of Using Iodopovidone as a Sclerosing Agent for Chemical Pleurodesis in a Tertiary Care Center: A Descriptive Cross-Sectional Study.

INTRODUCTION: Pleurodesis is a procedure to achieve symphysis between the two layers of pleura aimed at preventing the accumulation of either air or fluid in the pleural space. In Nepal, intrapleural instillation of the chemical sclerosing agent is more commonly done as  thoracoscopy facility is not easily available. However, iodopovidone is rarely used for this purpose in Nepal. The study aims to find the prevalence of success using iodopovidone as the chemical sclerosing agent. METHODS: The study included cases undergoing pleurodesis over a two-year period. The clinicodemographic data, diagnosis, treatment effect and treatment response were analyzed. The treatment response was graded as Treatment Success (Complete Response or Partial Response) and Treatment Failure. RESULTS: Pleurodesis was done in a total of 54 cases. Of those, 39 cases were Secondary Spontaneous Pneumothorax, 11 were Malignant Pleural Effusion, 3 were Primary Spontaneous Pneumothorax, and 1 was a case of Hepatic Hydrothorax. Among Secondary Spontaneous Pneumothorax, Pleurodesis was successful in 37 (95%) out of 39 cases, with 35 (90%) having a Complete Response and 2 (5%) having a Partial Response while 2 (5%) had Treatment failure. Among Malignant Pleural Effusion, treatment success was achieved in 6 (55%) out of 11, whereas 5 (45%) failed the treatment. The commonest complication was burning sensation, and the commonest pain scale was "distressing." CONCLUSIONS: This study highlights the safety and ease of use of iodopovidone as an agent for chemical pleurodesis. It confirms the high rate of success of pleurodesis in cases of pneumothorax as found in other studies. In contrast, the success rate is understandably lower in cases of Malignant Pleural effusion.

Mesothelioma with Nonbacterial Thrombotic Endocarditis: A Case Report.

Non-bacterial thrombotic endocarditis is a rare condition characterized by noninfectious vegetation on cardiac valves which are often associated with malignancy. It often presents with features of embolism rather than cardiac failure. These are usually seen in autoimmune conditions, disseminated intravascular coagulation, malignancy of gut and lung but has also been reported in other malignancies as well. This entity is rare but one must have a clinical suspicion of the disease especially in a patient suffering from malignancy presenting with the embolic phenomenon. In this report, we are presenting a case of non-bacterial thrombotic endocarditis in an inpatient with pleural mesothelioma, a rare malignant neoplasm arising from pleura in a 35 years old mason, and a rare association as well.

Rare Cause of Tension Pneumothorax: Hydatid Disease of Lung: A Case Report.

Lung is the second most common site of hydatid disease, after liver. Pleural involvement of hydatid disease can occur, and usually follows the rupture of a pulmonary or hepatic hydatid cyst into the pleural space. When a patient presents with tension pneumothorax, zoonotic infections, especially hydatid disease of the lung, also has to be considered especially in areas with high burden of the disease. We report a 31 years male patient presenting with tension pneumothorax due to rupture of hydatid cyst of lung.

Prevalence of Iron Deficiency Anemia in Biochemically Defined Moderate to Severely Anemic patients in a Tertiary Care Centre.

INTRODUCTION: Anemia due to iron deficiency and chronic diseases is common occurrence in developing country like Nepal, the latter seen in patients with various inflammatory, autoimmune, and malignant disorders . The Intensive method of marrow iron examination, which this study has employed, provides clinically useful iron status classification in cases of functional iron deficiency. The aim of the study is to find out the prevalence of iron deficiency anemia in biochemically defined moderate to severe anemic patients in tertiary care center. METHODS: A descriptive cross-sectional study was done in 43 patients who underwent bone marrow aspiration for evaluation of any cause and had moderate to severe anemia at the same time over a period of one year from Nov 2015 to 2016. Ethical clearance was obtained from Institutional Review Committee. The bone marrow iron stores were assessed by"intensive method" apart from the routinely used Gale's method. Data was collected and entry were done in Statistical Package for Social Sciences version 24. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: The intensive grading system demonstrated normal marrow iron store in 13 (30.2%), depleted iron stores in 3 (7%), functional iron deficiency in 14 (32.6%), and combined deficiency in 13 (30.2%) patients. Mean log ferritin concentration was lower in patients with depleted iron stores (2.2µg/l) than in those with normal (2.7µg/l), and functional iron deficiency (2.4µg/l). The mean log ferritin in combined deficiency was lower than the mean log ferritin concentration in iron store deficiency (1.9µg/l). CONCLUSIONS: The prevalence of functional iron deficiency anemia was greatest when the intensive method for assessment of bone marrow iron was used, thus differentiating four different iron status categories, including functional iron deficiency, from actual iron store deficiency, avoiding unnecessary iron supplementation in the former group.

Correlation of urinary cotinine with cardiovascular risk factors in pan masala tobacco users.

BACKGROUND: Tobacco consumption is considered as one of the major risk factors for cardiovascular (CV) morbidity. However, the effect of paan masala tobacco (PMT) (a type of smokeless tobacco) consumption has not been well studied in our context. Our study is aimed to find an association of CV risk factors between PMT users and nonusers and to correlate those parameters with urinary cotinine level, a degradation product of nicotine occurring in tobacco. METHODS: This comparative cross-sectional study was carried out among 200 participants. The effect of PMT use on CV risk factors such as blood pressure (BP), lipid profile, and body mass index was measured against urine cotinine level. Statistical tests used were χ2 test for categorical variable, independent t-test, Mann-Whitney U test, and Spearman's correlation applied for numerical variable, and multivariate regression analysis was performed as required. The level of significance was set at p < 0.05. RESULT: Mean BP, total cholesterol, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and median cotinine level were found to be significantly higher in PMT users than in controls (p < 0.001). Urinary cotinine level was positively correlated with mean BP, TC, TG, and LDL-C in PMT users (p < 0.001). Similarly, the odds of having hypercholesterolemia and increased diastolic BP was also significantly higher in PMT users (p < 0.001). CONCLUSION: PMT use has an adverse effect on CV risk parameters and there is a rational of cotinine measurement for screening CV risk among PMT users.

Air due to Glue: Spontaneous Pneumothorax in a Young Adult with Glue Sniffing.

Solvent abuse, as inhalant specially, in the form of low cost adhesives like dendrite is common in low income countries among children and the teens. This habit is often a stepping stone to harder drugs. The neurological and neuropsychological effects of solvent abuse are well explored. But the respiratory effects are often overlooked. In this report, we present a case of a 19 year old gentleman, with regular history of sniffing of commercial "glue" compounds. This patient presented with right sided chest pain and chest x-ray showed a right sided pneumothorax. The pulmonary barotrauma, possibly due to increased intra-alveolar pressure, during the sniffing process can lead to alveolar rupture and in turn, pneumothorax. In the absence of other risk factors for Pneumothorax, the link between inhalant abuse and respiratory complications has to be explored in patients with history of such abuse. Keywords: inhalant abuse; pneumothorax; solvent.

Anaphylactic reactions due to pantoprazole: case report of two cases.

BACKGROUND: Drug-induced hypersensitivity reaction is of great clinical significance in therapeutics. The objective of this reporting of two cases is to show that anaphylaxis reaction can occur with pantoprazole. CASE SUMMARIES: A 38-year-old female reported to the emergency ward in a critical condition, with a history of periorbital edema, edema of the skin, pruritus, nausea, vomiting, and difficulty breathing 20 minutes after ingestion of a pantoprazole 40 mg tablet. A 32-year-old female reported to the emergency ward in a critical condition, with complaints of rashes all over the body, itching on the whole body, and swollen lips and eyes after ingestion of a pantoprazole 40 mg tablet. CONCLUSION: It is necessary for all health care providers to know that pantoprazole can cause anaphylaxis, which is a life-threatening reaction, and to be cautious while prescribing it.

Incidence and Outcome of Ventilator Associated Pneumonia in ICU of a Tertiary Care Hospital in Nepal.

INTRODUCTION: Ventilator associated pneumonia is an important intensive care unit acquired infection in mechanically ventilated patients. Early and correct diagnosis of Ventilator associated pneumonia is difficult but is an urgent challenge for an optimal antibiotic treatment. METHODS: A prospective observational study was conducted in Intensive Care Unit of a tertiary care hospital in Nepal. Consecutive patients were considered during the study period, who met the criteria were included for the study. Clinical Pulmonary Infection Score was used to diagnose Ventilator associated pneumonia. RESULTS: Among 60 patients ventilated for more than 48 hours, 25 (41.6%) developed ventilator associated pneumonia. The incidence was 25 VAPs per 100 ventilated patients or 26 VAPs per 1000 ventilator days during the period of study. Days on ventilator and duration in ICU were higher in the VAP group. There was a trend towards increasing mortality in the VAP group (P value=0.06). CONCLUSIONS: There exists a high rate of VAP in our Intensive Care Unit. Targeted strategies aimed at reducing Ventilator associated pneumonia should be implemented to improve patient outcome and reduce length of Intensive Care Unit stay and costs.
