Background: Pulmonary tuberculosis (PTB) and paragonimiasis remain as health problems in certain areas in the Philippines. Both share similar clinical manifestations, which include chronic productive cough, hemoptysis, dyspnea, fever, weight loss, and night sweats. This study aimed to determine the prevalence of PTB, paragonimiasis, and co-infections in Zamboanga del Norte, Philippines. Methods: This study was conducted in selected villages in two municipalities in Zamboanga del Norte. Patients with chronic cough were interviewed, examined, and requested to submit two sputum samples which were processed using Ziehl-Neelsen method to detect acid-fast bacilli (AFB), and NaOH concentration technique for the detection of Paragonimus ova. Results: A total of 836 patients submitted sputum samples for examination. Prevalence was 6.7% (2.5-12.7%) for paragonimiasis and 1.9% (0.9-6.3%) for PTB. Co-infection rate was 0.3%, with two identified cases. Positivity rates for males and females were 9.6 and 5.8% for paragonimiasis and 3.4 and 1.2% for PTB. Conclusion: Pulmonary tuberculosis and paragonimiasis are co-endemic in Zamboanga del Norte, suggesting the need to integrate surveillance and control efforts. Strengthening local health systems through collaboration between different sectors is recommended for effective disease control. Development of more sensitive diagnostic tests is important for more accurate disease surveillance.
A 48-year-old man presented with a non-healing wound on his left foot after stepping on a nail. He self-medicated with amoxicillin, but the wound progressed prompting consult. On examination, his left foot was diffusely swollen with surrounding erythema, areas of gangrene, foul-smelling purulent discharge and subcutaneous emphysema. He was managed as a case of necrotising fasciitis and underwent emergent amputation. Three days after amputation, he developed a sudden and progressive blurring of vision, swelling and conjunctival erythema, with purulent discharge and the presence of hypopyon on the left eye. He was then managed as a case of endophthalmitis of the left eye and underwent pars plana vitrectomy. All cultures (blood, tissue and vitreous fluid) grew pan-susceptible hypermucoviscous Klebsiella pneumoniae, with positive string tests and confirmed by multilocus gene sequencing and sequence type analysis. He gradually improved with intravenous antibiotics, but only regained light perception in the left eye.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
