This study was designed to evaluate common risk factors for periodontitis and acute coronary syndrome in the study population and demonstrate the systemic impact of periodontitis on the occurrence of acute coronary syndrome. A total of 160 patients (35 female and 125 male) were enrolled in the study. Considering the age range, the largest group of patients (118 patients) was between 55 and 65 years, which accounted for 73.8% of the total study population. There were 35 patients (21.9%) in the age group of 45 to 54 years, while the youngest age group of 35 to 44 years had as many as seven patients. Medical history and physical examination, including periodontal status, were performed. API, PD, CAL, and CPITN were evaluated. Common risk factors for periodontitis and acute coronary syndrome were assessed. The study assessed risk factor...

Values of relative Cerebral Blood Volume (rCBV) and rCBV z-scores from frontal, temporal, parietal and PCG cortices were correlated with the rate of glucose metabolism from PET. Sensitivity, specificity and accuracy of DSC-MRI and FDG-PET in the diagnosis of AD and aMCI were assessed and compared.Results: In AD hypoperfusion was found within all examined locations, while in aMCI in both parietal and temporal cortices and left PCG. FDG-PET showed the greatest hypometabolism in parietal, temporal and left PCG regions in both AD and aMCI. FDG-PET was more accurate in distinguishing aMCI from controls than DSC-MRI. In AD and combined...

Similarly, a high prevalence of gingivitis and periodontitis is observed. There are reports in the literature about the interrelationship between chronic kidney disease and periodontitis pathophysiology. This dissertation attempts to: assess the extent of gingivitis and periodontitis in a group of patients with the end-stage renal disease treated with hemodialysis compared to healthy subjects. The study included 200 subjects: 100 hemodialysis patients (HD) and 100 healthy control subjects (K). Periodontal status was assessed by measuring pocket depth (PD) clinical level of connective tissue attachment (CAL). Gingival inflammation indices Gingival Index (GI) and Bleeding on Probing (BOP) were also performed. PD with a depth of more than 6mm was found in 25% of the HD group and 5% of the K group. CAL ≥ 5 mm was found in 55% of HD and 24% of the K group. As defined by Page and Eke, severe...

Lesions involving the apical and marginal periodontium are endo−perio (EPL) lesions. This study aimed to compare the treatment efficacy of endo−perio lesions using a standard treatment protocol and a standard diode laser-assisted treatment protocol. The 12 patients were divided into the study (a) and control (b) group. Periodontal indices, tooth vitality and mobility, occlusal status, and radiographic diagnosis were evaluated. Standard EPL treatment was then performed—without (a) and with (b) the use of diode laser (940 nm). Again, after six months, the above-mentioned parameters were evaluated and compared. The treatment of endo−perio lesions is a significant challenge for modern dentistry. Diode lasers are increasingly used in addition to traditional treatment methods. The conventional use of a 940...

This study examined local ('patch') scale spatial sampling patterns in the Atlas of Australian Birds and then compared reporting rates, i.e. the proportion of sampling units in which a given species was present, from a sample of atlas points with those from a regular sample. Three sites that have been were surveyed sequentially between January-May 2017: Killawarra Forest, Victoria, Coolah Tops National Park and Pilliga Nature Reserve, New South Wales. Spatial bias in atlas sampling patterns was evident as clusters at tourist areas and special habitat features and linear patterns along roads and creek lines. Atlas samples overestimated reporting rates for species with spatial distributions that were concordant with those sampling patterns and vice versa. At least twofold differences in atlas/regular sample reporting rate ratios were detected for between 13-15% of non-rare species (with reporting rates ≥ 0.08). Concerns are raised that spatial sampling bias is common in the atlas and affects a variety of species, that popular sites may not be representative of habitat patches and that a large proportion of surveys are being filtered out in data analyses.

The participants answered questionnaires about their lifestyle, underwent physical and psychological examination (MoCA test), laboratory blood tests followed by brain MRI. Volumetric measurements of the total gray matter (GMvol), total white matter (WMvol) and WHM (WMHvol) normalized to the total intracranial volume were performed using the Computational Anatomy Toolbox 12 (CAT12) and Statistical Parametric Maps 12 (SPM12) based on 3D T1-weighted sequence. The influence of risk factors was assessed using multiple reg...

The aim of the study was to assess the effect of ageing in women on coordinated brain activity between eight resting-state networks. Material and Methods: The study group comprised 60 healthy female volunteers who were divided into two age groups: younger women (aged 20–30 n = 30) and older women (aged 55–80 n = 30). Resting-state data were collected during a 15 min scan in the eyes-closed condition using a 3T MR scanner. Data were preprocessed and analysed using the CONN toolbox version 19.c. The large-scale network analysis included a priori selected regions of interest of the default mode, the sensorimotor, the visual, the salience, the dorsal attention, the fronto-parietal, the language, and the cerebellar network. Results: Within the visual, the default mode, the salience, and the sensorimotor network, the intra-network rest...

In this report, we describe a child with neuroblastoma who developed an extremely severe acute lung injury after granulocyte colony-stimulating factor was used for peripheral hematopoietic stem cell mobilization. A 3-year-old boy with a medical history of patent foramen ovale and secundum atrial septal defect was diagnosed with an MYCN-amplified neuroblastoma and treated with chemotherapy. During stem cell mobilization with filgrastim, the boy was in very good clinical condition, with a peripheral white blood cell (WBC) count of 57.17 K/μL, but he suddenly deteriorated, and nausea, seizures, and nystagmus were observed. The patient developed dyspnea with hemoptysis, and lung computed tomography showed bilateral asymmetrical pulmonary opacification demonstrating an anteroposterior density gradient. Because of rapidly progressing circulatory and respiratory failure, the child was hospitalized in the intensive care unit. Corticosteroid therapy, broad-spectrum antibiotic therapy, and cardiovascular support with mechanical ventilation were immediately instituted, and the child recovered without sequelae. The presented case emphasizes that life-threatening complications can occur during granulocyte colony-stimulating factor administration, and patient surveillance is warranted, especially if high leukocyte counts are observed or the patient exhibits cardiopulmonary signs.

It is characterized by intention myoclonus, cerebellar ataxia, and preserved intellect. The basis of the disease and its long-term prognosis remain unclear. Case report: The authors present a 53-year-old woman with a history of asthma bronchiale who suffered from myoclonus after hypoxic brain damage due to cardiac arrest. Advanced electrophysiological (quantitative EEG) and MR (MR spectroscopy) techniques were employed. Conclusions: Over long-term observation the results suggested permanent synaptic rearrangements of the neuronal networks due to brain plasticity in the patient after the brain hypoxia.

Rozwarstwienie tętnicy kręgowej występuje stosunkowo rzadko, z roczną częstością 1-1,5 na 100 tys. osób, ale wiąże się z poważnymi konsekwencjami. Obraz kliniczny jest bardzo niespecyficzny i zróżnicowany. Najczęstszy objaw to nagły, jednostronny ból głowy, któremu może towarzyszyć ból szyi. Wymienia się także zawroty głowy o charakterze układowym i nieukładowym oraz objawy wynikające z udaru bądź przejściowego niedokrwienia w tylnym obszarze unaczynienia mózgu, gdy rozwarstwienie dotyczy odcinka zewnątrzczaszkowego naczynia, lub krwotoku podpajęczynówkowegow przypadku rozwarstwienia wewnątrzczaszkowego odcinka tętnicy kręgowej. Etiologia rozwarstwienia jest różnoraka, związana z wieloma czynnikami. Wyodrębnia się rozwarstwienie urazowe, spowodowane najczęściej tępym urazem głowy i/lub szyi, oraz rozwarstwienia spontaniczne (samoistne). W przypadku rozwarstwienia samoistnego bierze się pod uwagę czynniki naczyniowe i genetyczne oraz zaburzenia w budowie ściany naczynia związane z chorobami tkanki łącznej. W przypadku podejrzenia rozwarstwienia tętnicy kręgowej rozpoznanie ustala się na podstawie wywiadu, objawów klinicznych i badań obrazowych. Złotym standardem diagnostycznym pozostaje klasyczna angiografia naczyń dogłowowych, a wśród badań nieinwazyjnych angiografia tomografii komputerowej wykazuje 100-procentową swoistość i czułość. W większości przypadków rozwarstwienie tętnicy kręgowej w odcinku zewnątrzczaszkowym wiąże się z dobrym rokowaniem. Leczenie ma charakter zachowawczy i obejmuje terapię lekami przeciwzakrzepowymi lub przeciwpłytkowymi. Leczenie chirurgiczne i wewnątrznaczyniowe stosuje się w określonych grupach pacjentów. Co ważne, nietypowe objawy kliniczne w początkowym okresie rozwarstwienia naczynia utrudniają diagnozę. Rozwarstwienie tętnicy kręgowej powinno być brane pod uwagę w przypadku udaru mózgu u osoby młodej, mimo niecharakterystycznych objawów i braku urazowego wywiadu. Słowa kluczowe: rozwarstwienie tętnicy kręgowej, udar niedokrwienny mózgu, uraz szyi, ból głowy, angiografia tomografii komputerowej Dissection of the extracranial carotid and vertebral arteries is responsible for 2-3% of all strokes and for 20% of ischaemic events in the population of young people under the age of 45. Vertebral artery dissection is a very rare yet serious condition. The annual overall incidence of vertebral artery dissection is estimated at 1 to 1.5 per 100 000 persons. Its clinical manifestation is very nonspecific and diverse. The most typical clinical sign is sudden unilateral headache accompanied by neck pain. Other symptoms include systemic and non-systemic headaches as well as infarction or transient ischaemic attack in posterior circulation territorial area inn case where the intracranial vertebral artery dissection is associated with subarachnoid haemorrhage. The aetiology of dissection remains unclear and connected with multiple risk factors. Vertebral artery dissection can be caused by blunt force trauma of the head or neck or it can be spontaneous. The aetiology of spontaneous vertebral artery dissection includes vascular and genetic factors as well as structural defects of the arterial wall associated with connective tissue disorders. The diagnosis of vertebral artery dissection has to be established based on anamnesis, clinical features and imaging examination. Catheter cerebral angiography is the gold standard of diagnosis of arterial dissection, but also computed tomography angiography has been proven to have a very high sensitivity and specificity. In most cases extracranial vertebral artery dissection carries a good prognosis. The treatment of vertebral artery dissection is conservative and includes the use of anticoagulation and antiplatelet drugs. Surgical or endovascular treatment can be applied only for selected and small group of patients.
