Chronic dietary exposure to aristolochic acid and kidney function in native farmers from a Croatian endemic area and Bosnian immigrants.

Background And Objectives: Improvements in agricultural practices in Croatia have reduced exposure to consumption of aristolochic acid-contaminated flour and development of endemic (Balkan) nephropathy. Therefore, it was hypothesized that Bosnian immigrants who settled in an endemic area in Croatia 15-30 years ago would be at lower risk of developing endemic nephropathy because of reduced exposure to aristolochic acid. To test this hypothesis, past and present exposure to aristolochic acid, proximal tubule damage as a hallmark of endemic nephropathy, and prevalence of CKD in Bosnian immigrants were analyzed.

Prevalence of genetic polymorphisms of CYP2C9 and VKORC1 - implications for warfarin management and outcome in Croatian patients with acute stroke.

Background: Data on the prevalence of CYP2C9 and VKORC1 genes and their influence on anticoagulant effect and warfarin dose in stroke patients are scarce. The aim of this study was to determine the occurrence and significance of these gene polymorphisms and to establish pharmacogenetic algorithm to estimate the dose of introduction. Also, the goal was to determine tailored safety and intensity of anticoagulation response depending on the allelic variants and their impact on the clinical outcome in acute stroke patients in Croatia.

Variation in presentation and presence of DNA adducts and p53 mutations in patients with endemic nephropathy--an environmental form of the aristolochic acid nephropathy.

Background: Endemic nephropathy (EN) and associated urothelial cell cancers (UUC) are an environmental form of aristolochic acid nephropathy where the most probable rout of ingestion of aristolochic acid (AA) was made by bread contaminated with AA, leading to chronic dietary intoxication. Clinical courses of three members of the same family, similarly exposed to toxin, who exhibited different clinical courses of the disease are presented.

Methods: Questionnaires on AA exposure were taken.

An infrequent type of stroke with an unusual cause and successful therapy: basilar artery occlusion caused by a cardiac papillary fibroelastoma recanalized 12 hours after onset.

We herein report the case of a 32-year-old woman with sudden onset ataxia, limb dysmetria and somnolence. Emergency radiological findings showed bilateral cerebellar and thalamic infarctions as a result of a basilar artery occlusion. The patient was treated with intra-arterial (IA) and mechanical thrombolysis 12 hours after symptom onset and showed an excellent recovery.

Beware of "old" Horner syndrome.

Purpose: Chronic Horner syndrome is a rare clinical condition, the etiology of which often remains undiscovered. A patient is presented with an 8-year history of Horner syndrome who was diagnosed with multiple cervical artery dissections.

Case Report: A 42-year-old woman presented to our emergency department with a severe occipital headache that woke her up from sleep 3 days earlier.

Systemic thrombolytic therapy in acute ischemic stroke--new experiences in spreading network of stroke units in Croatia.

Background: The aims of this paper are: 1) to present the data of systemic thrombolysis for ischemic stroke in five Croatian centers from July 2008 till January 2010; 2) to compare the results between centers and; 3) to compare data with previously published results from 2006 to 2008 period from our center, and with the data from SITS (Safe Implementation of Treatments in Stroke).

Methods: We retrospectively reviewed the medical data of thrombolysed patients in following hospitals: University Hospital Center Zagreb (91 patients), University Hospital Split (25 patients), University Hospital Osijek (22 patients), General Hospital Varaždin (21 patient), and General Hospital Zadar (7 patients).

Results: The "time to door" for all centers was 79.

Cardiac papillary fibroelastoma: source of cerebral embolism treated with intravenous thrombolysis.

We present the case of a 41-year-old man with sudden development of left hemiparesis due to infarction of the right middle cerebral artery that was successfully treated with intravenous (IV) thrombolysis with alteplase. Transthoracic echocardiography showed a small mass in the left ventricle. The patient underwent surgical resection, and histological examination of the mass confirmed the diagnosis of papillary fibroelastoma.

Systemic thrombolysis with recombinant tissue plasminogen activator in acute ischemic stroke: first Croatian experiences.

In September 2003, recombinant tissue plasminogen activator (rt-PA) for acute treatment of ischemic stroke was finally approved by the Croatian Ministry of Health. For the next 5 years, only three stroke units in the country implemented this therapy in their routine practice until summer 2008, when neurological wards in most Croatian hospitals started to treat acute stroke patients with systemic thrombolysis. We present a 2-year experience of thrombolytic therapy (2006-2008) in the stroke unit of the University Hospital in Zagreb, Croatian largest hospital, serving nearly one-fifth of the citizens of Croatia.

Isolated nontraumatic abducens nerve palsy.

Introduction: Abducens nerve palsy (ANP) is the most common isolated palsy. The injury of the abducens nerve can occur anywhere along its long course, so differential diagnosis of ANP occasionally demands thorough investigation to find the proper cause.

Patients: Ten patients with isolated ANP are presented.

[Classical type of Fabry disease without angiokeratomas--a case report].

A patient with classical type of Fabry disease is described. The appearance and character of neuropathic pain during hemodyalisis is described. Characteristic changes in head shape and changes of hands and fingers are the additional phenotypic characteristics of Fabry disease.

Series of seizures as a sign of development of recurrent malignant neuroleptic syndrome - a case report.

Neuroleptic malignant syndrome (NMS) is an uncommon but sometimes fatal complication of neuroleptics and other medications that involve the central dopaminergic system. Many diagnostic criteria have been proposed for NMS but because of its variable presentation, universal criteria have not been established yet. Hyperthermia, disturbances of consciousness, extrapyramidal and autonomic symptoms are common features of NMS.
