UNASSIGNED: Despite being generally treatable and preventative, pulmonary tuberculosis (PTB) is one of the most common infectious agents that cause death. Misdiagnosis of TB frequently leads to unwarranted diagnostic procedures and postpones the start of treatment.
UNASSIGNED: Pulmonary tuberculosis (PTB) can present with various unusual radiological and clinical characteristics. Misdiagnosis of TB frequently leads to unwarranted diagnostic procedures and postpones the start of treatment. Here, we describe a 50-year-old man who presented with a cancerous-type lesion on radiological findings and atypical symptoms that led to an initial diagnosis of lung cancer. However, histopathology and biopsy of the lung lesion revealed chronic granulomatous inflammation with caseous necrosis, confirming PTB as the true cause, with no further indications of malignancy.

The concurrent incidence of lung cancer and tuberculosis is expected to escalate due to the projected growth in the older population. Combination therapy with osimertinib and antituberculosis drugs has not been well-established. We report a case of successful treatment involving the concomitant administration of osimertinib and antituberculosis drugs in an older patient, an 89-year-old female, diagnosed with epidermal growth factor receptor (EGFR)-mutant lung cancer and pulmonary tuberculosis. Accumulating evidence is warranted to develop an optimal treatment strategy for patients with lung cancer and tuberculosis.

BACKGROUND: Tuberculosis (TB) in children under 15 years often results in airway compression, with bronchus intermedius (BI) being the most common site. Endoscopic enucleations can be used to remove lymph nodes and establish an airway in severe cases. Both rigid and flexible bronchoscopy are suitable, with alligator forceps being preferred for its ability to extract tissue. Recent studies have also explored cryoprobe enucleation.
METHODS: An HIV-positive boy with persistent symptoms after 9 months of TB treatment was diagnosed based on his mother\'s and sister\'s Xpert MTB/RIF positive status. He was started on 4-drug TB treatment, but the child remained clinically symptomatic with abnormal chest X-ray and unconfirmed TB. Bronchoscopy was performed, revealing complete obstruction of BI due to caseating granulomas causing collapse of the right middle and lower lobes. Cryotherapy was used to recanalize the airway, and follow-up bronchoscopy confirmed patent BI.
CONCLUSIONS: While cryotherapy was effective in the restoration of airway patency in this case, there is a lack of knowledge about its use in children.

Lemierre\'s syndrome is characterized by internal jugular vein thrombophlebitis and bacteremia, primarily from anaerobic organisms. The condition usually arises after a recent oropharyngeal infection. Young, healthy people with prolonged pharyngitis that progresses into septicemia, pneumonia, or lateral neck stiffness should be suspected of having Lemierre\'s syndrome. Identifying internal jugular vein thrombophlebitis and developing anaerobic bacterial growth on blood culture are frequently used to confirm the diagnosis. Treatment consists of long-term antibiotic treatment, sometimes in conjunction with anticoagulant medication. In this case report, we describe the unique case of a 29-year-old male with Mycobacterium tuberculosis with pulmonary tuberculosis, tubercular meningitis, tuberculosis-related acute ischemic stroke with septic thrombophlebitis. The patient presented with sudden onset altered sensorium for 4 hours. Magnetic resonance imaging of the brain was done, which suggested obstructive hydrocephalus with periventricular ooze. The patient was started on antibacillary treatment, antibiotics, anticoagulants, and systemic steroids. The patient was vitally stable when he was discharged. Therefore, it is crucial to consider the likelihood of such atypical tuberculosis presentations while providing a prompt and relevant diagnosis and recommending the right course of therapy.

Peritoneal tuberculosis (TB) is known to mimic advanced ovarian cancer. In this case report, we describe a unique case of ovarian cancer (endometrioid carcinoma grade 3) at the International Federation of Gynecology and Obstetrics (FIGO) stage IC1 with pulmonary and peritoneal TB, which was suspected preoperatively to be a coexistence of advanced ovarian cancer and pulmonary TB. A 68-year-old woman presented with a prominent abdominal mass and fever. Laboratory investigations, imaging, and sputum analysis indicated a probable diagnosis of ovarian cancer at FIGO stage IIIC, characterized by peritoneal dissemination and para-aortic lymph node metastasis, which was further complicated by coexisting pulmonary TB. Surgical management included total abdominal hysterectomy, bilateral salpingo-oophorectomy, and partial omentectomy. Intraoperatively, the tumor was localized to the right ovary with significant peritoneal thickening and adhesions indicative of peritoneal TB. The surgery was completed without apparent complications. Postoperative histopathological evaluation confirmed grade 3 endometrioid carcinoma in the right ovary along with evidence of peritoneal TB. Given the extent of adhesions attributed to TB, lymph node dissection for staging was deemed challenging and was thus not pursued. Initiation of anti-TB treatment on postoperative day 2 resulted in marked regression of the preoperatively identified pulmonary nodules and para-aortic lymph node enlargement, suggesting their inflammatory origin from TB. Although postoperative chemotherapy is typically advocated for patients with stage IC1 endometrioid carcinoma grade 3, the patient opted against it. Consequently, no adjuvant therapy was administered and the patient remained under close observation.

UNASSIGNED: Pulmonary tuberculosis (PTB) is a major public health concern in most underdeveloped and developing countries. PTB affects the nutritional status of the patients and influences the body mass index (BMI). There is tissue inflammation and free radical burst from activated phagocytes resulting in oxidative stress. The present study was designed to assess the relationship between oxidative stress and body mass index in newly detected pulmonary tuberculosis patients.
UNASSIGNED: This was a case-control study designed to assess oxidative stress parameters such as nitric oxide (NO) and malondialdehyde (MDA) in 40 consecutives newly diagnosed PTB patients and compared with 40 age-matched healthy controls. The nutritional status of the study subjects was measured by calculating the BMI.
UNASSIGNED: The mean BMI was 21.61±3.52 Kg/m2 in controls and 17.47±1.56 Kg/m2 in PTB patients and the difference was statistically significant (p <0.0001). The mean levels of MDA (7.65±0.65 nmol/ml) and NO (36.12±1.07 μmol/l) were significantly higher in PTB patients compared to controls (MDA 3.56±0.41 nmol/ml and NO 14.48±0.93 μmol/l).
UNASSIGNED: Increased levels of malondialdehyde and nitric oxide were observed in newly diagnosed PTB patients when compared to controls indicating oxidative stress in PTB. The BMI of these patients was significantly lower than the controls. Thus, it is concluded that there is an inverse relationship between oxidative stress and BMI in PTB patients and antioxidant supplementation in addition to nutritional intervention under the National Tuberculosis Elimination Program may help to improve the BMI and promote better recovery in these patients.

UNASSIGNED: Identifying pulmonary pathology while evaluating electrolyte disorders is crucial for optimal patient management. Physicians working in endemic regions of tuberculosis should consider this pathology as a differential for electrolyte imbalances.
UNASSIGNED: Hyponatremia, a common electrolyte imbalance, can arise from various underlying etiologies such as diuretics, diarrhea, vomiting, congestive heart failure, and liver and renal disease. We present a case report of a 74-year-old man highlighting the association between pulmonary tuberculosis (TB) and the development of hyponatremia. GeneXpert assay of the patient\'s sputum sample led to the identification of underlying active pulmonary TB as the cause of hyponatremia. The patient was started on anti-TB therapy, and concurrent fluid restriction and sodium supplementation were initiated to correct the electrolyte imbalance. Over the next 3 days, the patient demonstrated clinical improvement with the resolution of hyponatremia. This case also highlights the importance of considering TB as a potential etiology in patients presenting with hyponatremia, especially in endemic areas. Further research is warranted to explore the mechanistic pathways linking pulmonary TB and hyponatremia, aiding in the development of targeted therapeutic interventions.

BACKGROUND: Pulmonary tuberculosis (PTB) is prevalent in immunocompromised populations, including patients with hematologic malignancies, human immunodeficiency virus infections, and chronic diseases. Effective treatment for acute promyelocytic leukemia (APL) combined with PTB is lacking. These patients show an extremely poor prognosis. Therefore, studies should establish efficient treatment options to improve patient survival and prognosis.
METHODS: A 60-year-old male with pain in the right side of his chest and a fever for 4 d visited the outpatient department of our hospital. Peripheral blood smear revealed 54% blasts. Following bone marrow examinations, variant APL with TNRC18-RARA fusion gene was diagnosed. Chest computed tomography scan showed bilateral pneumonitis with bilateral pleural effusions, partial atelectasis in the lower lobes of both lungs, and the bronchoalveolar lavage fluid gene X-Pert test was positive, indicative of PTB. Carrimycin, ethambutol (EMB), and isoniazid (INH) were administered since he could not receive chemotherapy as the WBC count decreased continuously. After one week of treatment with carrimycin, the patient recovered from fever and received chemotherapy. Chemotherapy was very effective and his white blood cells counts got back to normal. After being given five months with rifampin, EMB and INH and chemotherapy, the patient showed complete remission from pneumonia and APL.
CONCLUSIONS: We report a case of PTB treated successfully with carrimycin with APL that requires chemotherapy.

Destroyed lung syndrome (DLS) refers to the irreversible and complete destruction of lung tissue, often due to chronic or recurrent lung infections. Pulmonary tuberculosis (PTB) is a prominent cause of this condition, particularly prevalent in regions burdened by high PTB rates. This report delineates the case of a 60-year-old Indian male who presented with DLS as a consequence of a history of irregular PTB treatment. The patient complained of a productive cough, hemoptysis, fever, and dyspnea. A comprehensive evaluation confirmed the diagnosis, prompting the re-initiation of antitubercular therapy. This case report highlights the challenges and consequences of irregular PTB therapy leading to severe lung damage, emphasizing the significance of prompt and consistent treatment in preventing such debilitating outcomes.
