  • Non-ketotic hyperglycaemia induced occipital reflex focal seizures
    Publication . Buque, Helena; Catamo, Deise; Felix, Catarina; André, Ana; Gil, Inês; Nzwalo, Hipólito
    A myriad of neurological manifestations can occur in association with ketotic and non ketotic hyperglycaemic states. Contrary to diabetic coma, which is a universal complication under relatively established metabolic circumstances, the pathophysiology beyond hyperglycaemicassociated positive neurological manifestations, including seizures, remains to be elucidated. The occurrence of symptomatic focal epilepsy as a manifestation of diabetes-related hyperglycaemia is seldom reported. Herein, we present a case of focal epilepsy with alternating positive and negative neurological manifestations as the initial manifestation of diabetes-related hyperglycaemia. The electroencephalogram confirmed the diagnosis of focal occipital seizures, and the brain magnetic resonance imaging depicted the associated typical transient imaging findings in the occipital lobe. Seizures were refractory to antiepileptics, and symptomatic control was achieved after achieving normoglycemia. On follow-up, complete clinical and imaging recovery occurred. Reflex focal epilepsy in the context of hyperglycaemic states is a rare condition, and the possibility of misdiagnosis is likely high. As reported in similar cases, seizures can be resistant to antiepileptics. An important message to highlight is that seizures associated with hyperglycaemic status can be resistant to antiepileptic treatment and only cease with glycaemic control.
  • Severe neurocysticercosis in a quaternary hospital from Mozambique: case series analysis
    Publication . Buque, Helena; Vaz, Deise; Lorenzo, Elder; Tané, Suraia; Sidat, Mohsin; Nzwalo, Hipólito
    Background: Neurocysticercosis (NCC) is severe and leading global cause of morbidity and mortality. The disease presents with a variety of clinical presentations from focal to diffuse neurological symptoms. Despite being an endemic country, there are no studies describing the clinico-epidemiological characteristics of NCC in Mozambique. Herein, we describe a consecutive cases series of NCC from the national reference Hospital in Maputo, capital of Mozambique. Methods: Consecutive cases of NCC diagnosed during a 3-year period (January/2020-December/2022) were retrieved from the institutional clinical files and imaging database. Results: Six cases of NCC were identified, with mean age of 43.1 years (range 26-66). Four were males (66.6 %). The median time from the beginning of clinical manifestations to the diagnosis was 6 months (range 3-18 months). All patients presented with severe parenchymal NCC, with seizures (n = 5, 83 %) being the most common manifestation. Other clinical manifestations were dementia (n = 1) and hydrocephalus (n = 1). The imaging showed multiple lesions at different stages, with half (n = 3) of them showing the coexistence of nodular calcified lesions at earlier stages (vesicular, colloidal and granular stages). Patients were treated with anthelminthic drugs, corticosteroids and anticonvulsants and no deaths to report. The 3rd month modified Rankin scale was & LE; 2 in 83 % of patients. Conclusion: In our case series, patients with NCC presented very late, with severe advanced stage disease, with multiple coexistent short and long-term brain lesions. These findings can be explained eventually because of the Maputo Central Hospital being national referral center receiving commonly more severe cases. Studies aiming to clarify the diagnosis pathways/barriers and NCC awareness among medical doctors working at primary and secondary health care level is mandatory to assess the real burden of NCC and implement timely diagnosis and care of patients affected by this neglected disease.
