Our knowledge on the susceptibility of humans to different genotypes of the zoonotic tapeworm and the genetic make-up of the cysts in multi-organ involvements is limited. This study aimed to identify the genotype profile of in patients undergoing hydatid surgery in an endemic area for cystic echinococcosis (CE) in southeastern Iran. Individuals who underwent hydatid cyst surgery were included in this study. Protoscoleces/germinal layers from each individual isolate were washed and kept in -20°C until use. Genotyping was carried out using PCR-sequencing of two mitochondrial CO1 and ND1 genes. Molecular phylogeny and haplotype network analysis of the human isolates were carried out using sequence data obtained from this study and National Center for Biotechnology Information (NCBI) databases. Forty-two patients (23 women and 19 men) participated in the study; the mean age was 43 years. Eighteen (42.9%) and 24 (57.1%) patients were infected by sensu stricto (G1-G3) and (G6 genotype), respectively. Molecular study showed mixed infection of G1 (in the liver and right lung) and G6 (in left lung) in a patient. The study showed a significantly high proportion of CE patients infected with the G6 genotype particularly in the southern parts of the province. In the present study a human CE patient infected by two species/genotypes of sensu lato is documented.

Background: Existing longitudinal cohort study data and associated biospecimen libraries provide abundant opportunities to efficiently examine new hypotheses through retrospective specimen testing. Outcome-dependent sampling (ODS) methods offer a powerful alternative to random sampling when testing all available specimens is not feasible or biospecimen preservation is desired. For repeated binary outcomes, a common ODS approach is to extend the case-control framework to the longitudinal setting.

Background: Scrub typhus (ST), also known as tsutsugamushi disease, is a common febrile vector-borne illness in South Korea, transmitted by trombiculid mites infected with Orientia tsutsugamushi, with rodents serving as the main hosts. Although vector-borne diseases like ST require both a One Health approach and a spatiotemporal perspective to fully understand their complex dynamics, previous studies have often lacked integrated analyses that simultaneously address disease dynamics, vectors, and environmental shifts.
Objective: We aimed to explore spatiotemporal trends, high-risk areas, and risk factors of ST by simultaneously incorporating host and environmental information.

Purpose: To describe differences in the expression of selected host biomarkers, by analysing the aqueous humour (AH), cerebrospinal fluid (CSF) and serum of patients with ocular syphilis, both with and without neurosyphilis and HIV infection, to support the diagnosis of ocular syphilis.
Methods: A prospective observational descriptive study was conducted at Tygerberg Academic Hospital in Cape Town, South Africa, from February 1, 2018, to January 31, 2021. The study included all patients aged 18 years or older who presented to the eye clinic with ocular syphilis, provided they had a positive serum Treponema pallidum antibodies (TPA) test, an RPR titre of ≥ 8 and confirmed ocular inflammation.

Background: Spring-mediated cranioplasty (SMC) is a safe and effective treatment for craniosynostosis. The authors describe the largest cohort of endoscopic SMC for coronal craniosynostosis to date, highlighting the evolution of their technique.
Methods: The authors retrospectively reviewed patients who underwent endoscopic coronal suturectomy and SMC between 2017 and 2023.

Background: Congenital accessory auricle is a common aurcile malformation, often associated with tragus malformation, impacting the appearance and psychology of patients. To optimize surgical treatments for congenital accessory auricle with tragus malformation, this article proposes a novel classification and explores surgical strategies.
Methods: This retrospective study included 120 patients with congenital accessory auricle and tragus malformation who underwent surgery between December 2019 and June 2024.
