Trichomonads are flagellated protozoa that have occasionally been detected in the human respiratory tract, although detection rates have often been underestimated. We applied a nested PCR assay targeting the 18S rRNA gene of trichomonads to induced sputum from asthma patients to determine the prevalence of Trichomonas. Induced sputum was collected from 41 adults with asthma and analyzed through nested PCR using broad-range trichomonad primers and DNA sequencing for species identification. Nested PCR detected trichomonad DNA in 10 of the 41 (24.4%) samples. Sequencing and phylogenetic analysis revealed Trichomonas tenax in 8 cases and Tetratrichomonas sp. in 2 cases. These findings indicate that trichomonads can be present in the lower airways of patients with asthma, warranting further investigation into their clinical relevance.

To characterize the bioaccessibility of inhaled organophosphate esters (OPEs) in the respiratory tract, we employed a highly idealized mouth-throat model to investigate the occurrence, distribution, and deposition of 17 OPEs in airborne particulate matter (PM, PM, and PM; = 80 pairs) and gas phases ( = 48) under gradient temperature and humidity. OPEs concentrations were also measured in exhaled breath condensate (EBC; = 50) and sputum ( = 30) from 30 adults. Total median ∑OPEs concentrations in inhaled air were 4.

Background: commonly colonizes the genitourinary tract and primarily affects immunocompromised individuals. It is mostly confined to localized infections, with bloodstream dissemination being rare. Because of its fastidious nutritional requirements, the organism is seldom recovered by routine blood culture, and the absence of a cell wall renders it intrinsically resistant to many first-line antimicrobials.

Tuberculous meningitis (TBM) is predominantly observed in developing countries but remains relatively rare in developed countries. Therefore, if a clinician does not suspect TBM, its diagnosis may be delayed. Furthermore, drug-induced hepatotoxicity is common and can become severe during TBM treatment.

Extrapulmonary tuberculosis (TB), particularly when it involves the central nervous system (CNS), remains a significant clinical challenge. Cerebral tuberculoma, though rare, can present with complex symptoms that overlap with other neurological conditions, making timely diagnosis difficult. The condition demands a multidisciplinary approach for accurate diagnosis and effective management, especially in patients with multiple comorbidities.

Background: Dyspnea is a common clinical symptom and cause of outpatient and inpatient presentations to the clinic. Diagnostic and therapeutic challenges appear, when additional diseases appear that are themselves associated with subjectively perceptible dyspnea. We report on a young woman with orthopnea as a trigger of a diagnostic cascade of various diseases.
