Background: NCC is a neglected zoonotic disease with high endemicity and disease burden. Neurocysticercosis is a frequent cause of seizures in endemic countries. Early diagnosis and therapy helps in reducing morbidity and DALYs (daily adjusted life years) lost. Definite diagnosis still relies on neuroimaging identification of scolex or by histopathological examination. Molecular method such as PCR (Polymerase Chain Reaction) is an emerging modality to supplement or complement these Gold standard methods.
Aim: To determine the utility of PCR in detecting Taenia Solium DNA in NCC patients.
Methods: A total of 100 blood samples of cases of NCC and 50 control blood samples, 58 urine samples of NCC cases and 24 control samples were collected. Repetitive element PTsol9 of the Taenia Solium was targeted.
Results: The sensitivity and specificity of PCR in blood samples was 57% and 94%, while sensitivity and specificity in urine samples was 64% and 87%.
Conclusion: PCR assay can be used as an adjunct for the diagnosis of NCC especially in ambiguous cases, this is relatively rapid and non-invasive diagnostic modality.

Taenia solium is a parasite and is endemic in the developing countries due to various unhygienic faecal practices. The disseminated form is commoner with the brain being the most common site of affliction. This report is of a young female patient with complaints of an insidious and progressive swelling of the right forearm.

Background: Cysticercosis, a parasitic infection caused by the larval stages of the pork tapeworm, Taenia solium, predominantly affects cerebral and ocular tissues. The subcutaneous manifestation of this disease is a relatively uncommon clinical occurrence. Previously very few or no cases of cysticercosis presenting as subcutaneous solitary painful swelling have been reported in the literature.

Purpose: Ocular cysticercosis, caused by larvae, presents significant public health challenges, especially in regions with poor sanitation. Traditional imaging techniques often fail to detect anterior segment cysticercosis accurately, necessitating the exploration of more advanced diagnostic modalities like Ultrasound Biomicroscopy (UBM).
Patients And Methods: A retrospective observational analysis was conducted on 18 eyes from 14 patients with cysticercosis involving the anterior segment.

Article Synopsis
- - Cysticercosis is a parasitic infection caused by the pork tapeworm, often linked to chronic headaches and epilepsy in areas like Latin America and Asia, especially when it affects the central nervous system (neurocysticercosis).
- - A serosurvey in Starr County, Texas, identified a 7.4% prevalence of cysticercosis among Mexican-American adults, with brain imaging revealing neurocysticercosis lesions in 2 of the 45 seropositive individuals.
- - Factors such as being female, working in healthcare or social services, and having an indoor job were significantly associated with a higher likelihood of being seropositive, indicating a need for more research on
