Private wells as potential sources of heavy metal exposure: a pilot study in northwest Slovakia.

Objectives: The aim of this study is to analyse levels of selected heavy metals: chromium (Cr), cadmium (Cd), copper (Cu), manganese (Mn), and lead (Pb), and to recognize factors related to wells' stewardship.

Methods: The pilot study was realized in May 2018 in three villages in northwest of Slovakia. We analysed 69 water samples from private wells.

Determination of Cadmium and Chromium in Fruit Spirits Intended for Own Consumption Using Graphite Furnace Atomic Absorption Spectrometry.

Introduction: Analysis of the occurrence of cadmium and chromium in selected samples of fruit spirits intended for own consumption.

Material And Methods: In our pilot study, we analysed 89 samples of fruit spirits intended for own consumption. The samples were mineralized with use of microwave decomposition system MULTIWAVE 60 50 Hz and analysed by atomic absorption spectrometry with a graphite furnace (AAS GBC XPLORAA 5000 with GF 5000).

Association of the role of personal variables and nonoccupational risk factors for work-related carpal tunnel syndrome.

Objectives: The purpose of this study was to identify personal variables and nonoccupational risk factors for carpal tunnel syndrome and to analyse the strength of association of these factors.

Methods: We performed a case-control study with 162 cases and 300 controls. We studied consecutive patients with an electrophysiologically confirmed diagnosis of symptomatic carpal tunnel syndrome.

Lead contamination of fruit spirits intended for own consumption as a potential overlooked public health issue? A pilot study.

Objective: The aim of the study was to analyse the occurrence of lead in selected samples of fruit distilled spirits for own consumptions in terms of possible contribution to the occurrence of alcohol-attributable diseases.

Methods: In a pilot study, we analysed 18 samples of fruit spirits for own consumption. Most of the samples were distilled in the local growing distilleries in the Žilina Region with exception of 3 samples collected in the Trnava Region (one of them was of Hungarian origin).

Clinical evaluation of coronally advanced flap with or without platelet-rich fibrin for the treatment of multiple gingival recessions.

Objectives: The aim of this randomized, controlled study was to assess the clinical effect of platelet-rich fibrin (PRF) in combination with coronally advanced flap (CAF) on root coverage, esthetics, and patient satisfaction when compared to CAF alone for the treatment of multiple Miller class I recessions.

Materials And Methods: A total of 24 patients with 52 Miller class I multiple recessions ≥ 3 mm were included and divided into CAF + PRF and CAF groups. At baseline and 12 months after surgery, recession height (RH), keratinized tissue height, gingival thickness (GT), and mean and complete defect coverage were evaluated.
