Chest X-ray findings in drug-sensitive and drug-resistant pulmonary tuberculosis patients in Uganda.

Background: Tuberculosis (TB) is one of the leading causes of death worldwide. Radiology has an important role in the diagnosis of both drug-sensitive (DS) and rifampicin-resistant (RR) pulmonary TB (PTB). This study aimed to compare the chest x-ray (CXR) patterns of microbiologically confirmed DS and RR PTB cases stratified by HIV serostatus in Uganda. Methods: We conducted a hospital-based retrospective study at the Mulago National Referral Hospital (MNRH) TB wards. All participants had a microbiologically confirmed diagnosis of PTB. CXR findings extracted included infiltrates, consolidation, cavity, fibrosis, bronchiectasis, atelectasis, and other non-lung parenchymal findings. All films were examined by two independent radiologists blinded to the clinical diagnosis. Results: We analyzed CXR findings of 165 participants: 139 DS- and 26 RR-TB cases. The majority (n = 118, 71.7%) of the participants were seronegative for HIV. Overall, 5/165 (3%) participants had normal CXR. There was no statistically significant difference in the proportion of participants with consolidations (74.8% versus 88.5%; p = 0.203), bronchopneumonic opacities (56.1% versus 42.3%, p = 0.207) and cavities (38.1% versus 46.2%, p = 0.514), across drug susceptibility status (DS versus RR TB). Among HIV-infected participants, consolidations were predominantly in the middle lung zone in the DS TB group and in the lower lung zone in the RR TB group (42.5% versus 12.8%, p = 0.66). HIV-infected participants with RR TB had statistically significantly larger cavity sizes compared to their HIV uninfected counterparts with RR TB (7.7 ± 6.8 cm versus 4.2 ± 1.3 cm, p = 0.004). Conclusions: We observed that a vast majority of participants had similar CXR changes, irrespective of drug susceptibility status. However, HIV-infected RR PTB had larger cavities.The diagnostic utility of cavity sizes for the differentiation of HIV-infected and non-infected RR TB could be investigated further.

The prevalence of concurrent pulmonary and extrapulmonary tuberculosis in Uganda: a retrospective study.

Background: Concurrent pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB) is associated with poor treatment outcomes yet its epidemiology in Uganda is unknown. The purpose of this study was to determine the prevalence, associated factors, and treatment outcomes of concurrent PTB and EPTB among patients at a national tuberculosis (TB) treatment center located at Mulago National Referral Hospital in Kampala, Uganda. Methods: We conducted a retrospective review of charts for people with TB who were enrolled in care between January 2015 and December 2019. Eligible charts were for people with pulmonary bacteriologically confirmed TB enrolled into care in the period under study. Concurrent PTB and EPTB was defined as PTB and bacteriological, histopathological, and/or radiological features of TB at another noncontiguous sites. Results: Overall, 400 patient charts were eligible, of whom 240 (60.0%) were aged 15-34 years and 205 (51.3%) were female. The prevalence of concurrent PTB and EPTB was 8.5% (34/400) [95% confidence interval (CI): 6.0-11.7%]. People with concurrent PTB and EPTB were more likely to have at least one comorbidity (82.4% versus 37.2%, p < 0.001), of which HIV was the most frequent. Furthermore, people with concurrent PTB and EPTB were more likely to have empyema (15% versus 2.6%, p = 0.028) but less likely to have bronchopneumonic opacification (0.0% versus 15.3%, p = 0.043) on chest x-ray imaging. People with concurrent PTB and EPTB had higher mortality (26.5% versus 6.37%) and a lower cure rate (41.2% versus 64.8%), p = 0.002. Conclusion: Our findings highlight the need for early detection of TB before dissemination particularly among people who use alcohol and people with HIV.

Overlapping holoprosencephaly-polydactyl syndrome and asphyxiating thoracic dystrophy, an incidental finding in late prenatal ultrasound: A rare case report.

Holoprosencephaly-polydactyly syndrome and asphyxiating thoracic dystrophy rarely overlap but if they do, they have poorer prognosis. Early prenatal detection of multiple congenital anomalies plays a crucial role in the management of pregnancy.

Thyroid hemiagenesis with a TI-RADS 2 nodule in the contralateral lobe.

BACKGROUND: Thyroid hemiagenesis is a rare congenital anomaly in which one lobe of the thyroid gland fails to develop. There is an increased incidence of associated thyroid disorders in patients with thyroid hemiagenesis. CASE PRESENTATION: A 32-year-old Ugandan woman presented with a complaint of painless neck swelling of 3-months duration. The swelling was associated with a globus sensation. There was no history of thyroid - related problems or treatment prior to this presentation. Physical examination demonstrated a mobile right thyroid swelling without an obvious nodular contour. Neck ultrasound showed an absent left lobe of thyroid gland, a right lobe with a solitary nodule scoring two points on the Thyroid Imaging, Reporting and Data System (TI-RADS) and an isthmus in situ. Extensive search for possible ectopic thyroid tissue was negative. She was biochemically euthyroid. The patient was counseled about thyroid hemiagenesis and was put on a regular follow up in the clinic for the TI-RADS 2 nodule. CONCLUSION: Thyroid hemiagenesis is often associated with other thyroid disorders. Its diagnosis should prompt an active search for other associated morphological or functional thyroid abnormalities.

T-cell non-Hodgkin's lymphoma of both breasts: An uncommon presentation of a common disease.

Secondary T-cell non-Hodgkin's lymphoma of the breasts is a very rare disease and can be easily missed as inflammatory carcinoma at initial presentation. High index of suspicion and radiological investigations has a big role in identifying the primary lymphoma.

Mature cystic teratoma of anterior mediastinum in a 4-month-old infant: a rare case report.

Teratomas of anterior mediastinum are rare tumors and are often slow growing, asymptomatic and detected incidentally on chest imaging. We report, a rare case of an anterior mediastinal teratoma occurring in early childhood. A 4-month-old male infant presented to the pediatric unit of our hospital with a 2-week history of a progressive difficulty in breathing and stridor. He had received several courses of oral and intravenous antibiotics for a clinical diagnosis of pneumonia. The baby started to show social smile and hold his head fairly steady. Chest radiography and chest ultrasound revealed a cystic anterior mediastinal mass which was confirmed by a contrasted chest CT. An ultrasound-guided trucut biopsy of the mass was performed and histopathology showed mature cystic teratoma. Surgical removal of the mass was done with excellent post-operative outcome. Occurrence of a mature cystic anterior mediastinal teratoma is uncommon in early infancy. Early and complete surgical resection offers the best possible prognosis.

COVID-19, HIV-Associated Cryptococcal Meningitis, Disseminated Tuberculosis and Acute Ischaemic Stroke: A Fatal Foursome.

BACKGROUND: Several viral, bacterial and fungal co-infections have been associated with increased morbidity and mortality among patients with COVID-19. We report a fatal case of severe COVID-19 pneumonia in a patient with a recent diagnosis of advanced HIV disease complicated by cryptococcal meningitis, disseminated tuberculosis and acute ischemic stroke. CASE PRESENTATION: A 37-year-old Ugandan woman was diagnosed with HIV infection 8 days prior to her referral to our center. She was antiretroviral naïve. Her chief complaints were worsening cough, difficulty in breathing, fever and altered mental status for 3 days with a background of a 1-month history of coughing with associated drenching night sweats and weight loss. The reverse transcriptase-polymerase chain reaction for SARS-CoV-2 of her nasopharyngeal swab sample was positive. Chest radiograph demonstrated military pattern involvement of both lungs. The serum and cerebrospinal fluid cryptococcal antigen tests were positive. Urine lipoarabinomannan and sputum GeneXpert were positive for Mycobacterium tuberculosis. Computed tomography of the brain showed a large acute ischemic infarct in the territory of the right middle cerebral artery. Regardless of the initiation of treatment, that is, fluconazole 1200 mg once daily, enoxaparin 60 mg, intravenous (IV) dexamethasone 6 mg once daily, oral fluconazole 1200 mg once daily, IV piperacillin/tazobactam 4.5 g three times daily and oxygen therapy, the patient passed on within 36 hours of admission. CONCLUSION: Co-infections worsen COVID-19 outcomes.
