Sound Around the World: Ultrasound for Tropical Diseases.

Ultrasound for diagnosis and staging of schistosomiasis and echinococcosis have paved the way over the past several decades for the application of ultrasound in tropical diseases. Until recently, the size and cost of ultrasound systems limited the application in low-resource settings. The increase in portable ultrasound systems has given more clinicians access to ultrasound, and clinically based protocols for the care of patients have emerged, such as focused assessment with sonography for HIV/TB and tropical cardiac ultrasound.

Point-of-care lung ultrasound for diagnosis of Pneumocystis jirovecii pneumonia: notes from the field.

Background: Thoracic ultrasound is helpful to evaluate lung pathology in patients with acute dyspnea. Several studies have demonstrated the efficacy of point-of-care ultrasound in patients with extrapulmonary TB and HIV co-infection. This retrospective, open-label case-control study explores the role of lung ultrasound in the diagnosis of Pneumocystis jirovecii pneumonia (PJP) in HIV-positive patients.

Utility of Point-of-care Ultrasound in Children With Pulmonary Tuberculosis.

Background: Point-of-care ultrasound (POCUS) detects extrapulmonary tuberculosis (EPTB) in HIV infected adults but has not been evaluated in children despite their higher risk of EPTB. This study's aims were to investigate feasibility of POCUS for EPTB in children, frequency of POCUS findings suggestive of EPTB and time to sonographic resolution of findings with treatment.

Methods: This prospective South African cohort study enrolled children with suspected pulmonary tuberculosis (PTB).

Case Report: Cysticercosis: Sonographic Diagnosis of a Treatable Cause of Epilepsy and Skin Nodules.

A case of disseminated cysticercosis of brain, muscle subcutaneous tissue is reported and the use of musculoskeletal ultrasound in the diagnosis of the condition emphasized.

Lessons Learned From Option B+ in the Evolution Toward "Test and Start" From Malawi, Cameroon, and the United Republic of Tanzania.

The acceleration of prevention of mother-to-child transmission (PMTCT) activities, coupled with the rollout of 2010 World Health Organization (WHO) guidelines, led to important discussions and innovations at global and country levels. One paradigm-shifting innovation was Option B+ in Malawi. It was later included in WHO guidelines and eventually adopted by all 22 Global Plan priority countries.

Sonographic Findings of Abdominal Tuberculosis in Children With Pulmonary Tuberculosis.

Ultrasound reports of 102 children with microbiologically confirmed or clinically diagnosed pulmonary tuberculosis (TB) showed that 23 of 37 (64%) and 23 of 65 (36%) had TB suggestive abdominal lymphadenopathy, and 16 of 37 (44%) and 8 of 65 (13%) had splenic microabscesses, respectively. Splenic microabscesses were associated with HIV infection (P = 0.041).

Ultrasound for patients in a high HIV/tuberculosis prevalence setting: a needs assessment and review of focused applications for Sub-Saharan Africa.

Ultrasound is increasingly used in point-of-care applications and has great potential to support the diagnosis of infectious diseases, especially in resource-limited settings. A cross-sectional study was performed involving 100 Malawian patients with a clinical indication for ultrasound. Furthermore, the literature on point-of-care ultrasound (POCUS) in Sub-Saharan Africa was reviewed to establish its applicability, most frequent indications, findings, and implications for treatment, and therefore relevance in POCUS curricula, with a main focus on infectious diseases.

Peripheral neuropathy in HIV-positive patients at an antiretroviral clinic in Lilongwe, Malawi.

Peripheral neuropathy (PN) is common in the setting of antiretroviral (ARV) programmes in resource-limited settings and poses significant challenges in assessment and management. A retrospective analysis was undertaken of prevalence and management of PN in a cohort of 3341 patients on highly active antiretroviral therapy. A first line ARV regimen containing stavudine (D4T) is used for clinically eligible patients.
