Background: Patients with cutaneous malignant melanoma (CMM) are at increased risk of non-melanoma skin cancers (NMSCs) and possibly precancerous lesions.
Objectives: To analyse the association between CMM and not only NMSCs but also precursor lesions, actinic keratosis (AK) and Bowen disease (BD).
Materials & Methods: The Finnish Cancer Registry data was used to calculate the age-standardized incidence ratio during 2000-2013 for basal (BCC) and squamous (SCC) cell carcinoma in patients with CMM.
When used appropriately, buprenorphine and oxycodone are safe drugs. They are, however, widely abused in combination with other drugs. Here we describe a case series of 8 patients with cervical myelopathy and rhabdomyolysis of the adjacent deep neck muscles after using an opioid in combination with other drugs.

This study aims to update the knowledge on the neuropathology of iNPH and to develop the neuropathological diagnostic criteria of iNPH. We evaluated the clinical lifelines and post-mortem findings of 29 patients with possible NPH.

Purpose: To analyse the 543 melanoma samples in 524 subjects collected during 2000-2013 at Kuopio University Hospital and reposited in the Biobank of Eastern Finland.
Translation of promising experimental therapies from rodent models to clinical success has been complicated as the novel therapies often fail in clinical trials. Existing rodent glioma models generally do not allow for preclinical evaluation of the efficiency of novel therapies in combination with surgical resection. Therefore, the aim of the present study was to develop a larger animal model utilizing lentivirus vector‑mediated oncogenic transformation in the rabbit brain.

Disease State Index (DSI) is a method to combine data from various sources for differential diagnosis and progression of neurodegenerative disorders.
Objective: To apply DSI to predict clinical AD in shunted iNPH-patients in a defined population.
Background: Idiopathic normal pressure hydrocephalus (iNPH) is frequently associated with concomitant amyloid-β (Aβ) pathology.
Objective: To compare the [11C]PIB PET uptake in the patients with suspected iNPH to Aβ and hyperphosphorylated-tau (HPτ) in the right frontal cortical biopsy, the cerebrospinal fluid (CSF) Aβ, the response to a CSF shunt, and the final clinical diagnosis of Alzheimer's disease (AD).
Methods: Patients (n = 21) from Kuopio NPH Registry (http://www.
Background: It remains unclear how intracranial pressure (ICP) measures are associated with brain biopsies and radiological markers. Here, we aim to investigate associations between ICP and radiological findings, brain biopsies, and shunt surgery outcome in patients with suspected idiopathic normal pressure hydrocephalus (iNPH).
Method: In this study, we retrospectively analyzed data from 73 patients admitted with suspected iNPH to Kuopio University Hospital.
Mutations in the progranulin (GRN) gene represent about 5-10% of frontotemporal lobar degeneration (FTLD). We describe a proband with a novel GRN mutation c.687T>A, p.

Disease State Index (DSI) is a statistical method that merges multimodal data to assist clinical decision-making. It has previously been shown to be useful in predicting progression in mild cognitive impairment and differentiating Alzheimer's disease (AD) and frontotemporal dementia.

Introduction: The incidence of Creutzfeldt-Jakob disease (CJD) in Finland in 1974-1989 was reported to be 0.6/1 000 000. Our aim was to compare the current incidence of CJD in Finland with the earlier incidence and also study the diagnostics of the disease.
View Article and Find Full Text PDFBackground: Amyloid-β (Aβ1 - 42), total tau (T-tau), and phosphorylated tau (P-tau181) in the cerebrospinal fluid (CSF) are the most promising biomarkers of Alzheimer's disease (AD). Still, little is known about the dynamics of these molecules in the living brain. In a transgenic mouse brain, soluble Aβ decreases with increasing age and advanced Aβ pathology as seen similarly in CSF.
View Article and Find Full Text PDFBackground: The significance of amyloid precursor protein (APP) and neuroinflammation in idiopathic normal pressure hydrocephalus (iNPH) and Alzheimer's disease (AD) is unknown.
Objective: To investigate the role of soluble APP (sAPP) and amyloid beta (Aβ) isoforms, proinflammatory cytokines, and biomarkers of neuronal damage in the cerebrospinal fluid (CSF) in relation to brain biopsy Aβ and hyperphosphorylated tau (HPτ) findings.
Methods: The study population comprised 102 patients with possible NPH with cortical brain biopsies, ventricular and lumbar CSF samples, and DNA available.
Unlabelled: BACKGOUND/OBJECTIVE: To determine the level of association between uptake of the amyloid positron emission tomography (PET) imaging agent [(18)F]flutemetamol and the level of amyloid-β measured by immunohistochemical and histochemical staining in a frontal cortical region biopsy site.
Methods: Seventeen patients with probable normal pressure hydrocephalus (NPH) underwent prospective [(18)F]flutemetamol PET and subsequent frontal cortical brain biopsy during ventriculoperitoneal shunting. Tissue amyloid-β was evaluated using the monoclonal antibody 4G8, thioflavin S and Bielschowsky silver stain.
Background: Idiopathic normal pressure hydrocephalus (iNPH) causes cognitive decline that can be alleviated by shunting, but long-term outcome studies are scarce.
Objective: To elucidate the long-term cognitive condition of shunt-responsive iNPH patients.
Methods: The follow-up data (Kuopio University Hospital NPH Registry) of 146 patients diagnosed with iNPH by clinical and radiological examination, 24-hour intraventricular pressure monitoring, frontal cortical biopsy, and response to the shunt were analyzed for signs of dementia.

Objective: To investigate the association of apolipoprotein E (APOE) genotype, especially the APOE4 allele, to (1) idiopathic normal pressure hydrocephalus (iNPH) and (2) amyloid-β (Aβ) plaques in cortical brain biopsies of presumed NPH patients with and without a final clinical diagnosis of Alzheimer's disease (AD).
Methods: 202 patients with presumed NPH were evaluated by intraventricular pressure monitoring and frontal cortical biopsy immunostained against Aβ (134 semiquantified by Aβ plaques/mm2). The 202 patients and 687 cognitively healthy individuals were genotyped for APOE.
Introduction: Heteroplasmic mitochondrial DNA (mtDNA) mutations are an important cause of childhood disorders, but the role of homoplasmic mtDNA mutations in severe neonatal manifestations is not well understood.
Methods: The following were performed: full mtDNA sequencing for mutation detection, blue-native protein analysis of autopsy-derived tissues to detect respiratory chain (RC) deficiency, light and electron microscopy for morphologic analysis, and northern blot and computational modeling to study the effect of mtDNA mutations on transfer RNA (tRNA) stability.
Results: We describe data from a patient with fatal neonatal lactic acidosis caused by a novel homoplasmic mutation at a highly conserved nucleotide G7453A within the tRNA(Ser (UCN)) in mtDNA.
Normal pressure hydrocephalus (NPH) can be alleviated by cerebrospinal fluid shunting but the differential diagnosis and patient selection are challenging. Intraventricular intracranial pressure monitoring as part of the diagnostic workup as well as shunting enable to obtain cortical brain biopsies to detect amyloid-β (Aβ) and hyperphosphorylated tau (HPτ), the hallmark lesions of Alzheimer's disease (AD). In possible NPH, Aβ alone indicates an increased risk of AD and when present with HPτ probable AD, but the effect of those brain lesions on survival is not known.

The major mediators in the secretory granules of the MC(TC) type of mast cells, serine proteinases tryptase and chymase, may be involved in squamous cell carcinoma (SCC) lesions by inducing matrix remodeling and epithelial cell detachment. The objective of this study was to analyze immunohistochemically whether MC(TC) mast cells as well as protease inhibitors, squamous cell carcinoma antigens (SCCAs), are present in the uterine cervical SCC.

Methods: Between 1991 and 2006 we evaluated 468 patients with suspected normal pressure hydrocephalus with intraventricular pressure monitoring and a right frontal cortical biopsy sample immunostained for Aβ and hyperphosphorylated tau (HPτ). Adequate samples and the clinical follow-up data until death or the end of 2008, available in 433 cases, were reviewed for the clinical signs of dementia, including AD.
Background: Previous reports showed that mast cells can typically be found in the peritumoral stroma of cervix carcinomas as well as in many other cancers. Both histamine and TNF-alpha are potent preformed mast cell mediators and they can act simultaneously after release from mast cells. Thus, the effect of TNF-alpha and histamine on cervical carcinoma cell lines was studied.
