BACKGROUND: Post-extraction alveolar bone loss, mostly affecting the buccal plate, occurs despite regenerative procedures. To better understand possible determinants, this prospective case series assessed gingival blood perfusion and tissue molecular responses in relation to post-extraction regenerative outcomes. METHODS: Adults scheduled to receive bone grafting in maxillary, non-molar, single tooth extraction site were recruited. Clinical documentation included probing pocket depth (PD), keratinized tissue width (KT), tissue biotype (TB), plaque (P) and bleeding...

CONTEXT: Lung is the most common site of small cell carcinoma (SCLC) - a poorly differentiated neuroendocrine carcinoma (PDNEC). SCLC comprises 15-20% of the invasive cancers of the lung. AIM: This study was conducted to appraise the accuracy and pitfalls of the diagnosis of PDNEC on cytology along with treatment responses if available. SETTINGS AND DESIGN: Retrospective study for 2 years yielded 21 cases on cytology. SUBJECTS AND METHODS: Slides of fine-needle aspiration of lymph nodes, the tumor, bronchial brush, and bronchoalveolar lavage specimens were used...

The authors report the successful repair of a Crawford type III thoracoabdominal aortic aneurysm (TAAA) with a thrombosed infrarenal component using a modified hybrid technique without aortic clamping in a high-risk patient. A 64-year-old male with a history of hypertension, diabetes, and severe chronic obstructive pulmonary disease presented with acute on chronic backache and bilateral short distance claudication. A computerized tomography scan demonstrated a large, nonleaking Crawford type III TAAA with thrombosed infrarenal component of the aneurysm...

BACKGROUND: Hemoptysis, i.e., the expectoration of blood from the lower airways, has an annual incidence of approximately 0.1% in ambulatory patients and 0.2% in inpatients. It is a potentially life-threatening medical emergency and carries a high mortality. METHODS: This review article is based on pertinent publications retrieved by a selective search in PubMed. RESULTS: Hemoptysis can be a sign of many different diseases. Its cause remains unknown in about half of all cases...

Computerized tomography (CT) is a widely adopted modality for analyzing directly or indirectly functional, biological and morphological processes by means of the image characteristics. However, the potential utilization of the information obtained from CT images is often limited when considering the analysis of quantitative information involving different devices, acquisition protocols or reconstruction algorithms. Although CT scanners are calibrated as a part of the imaging workflow, the calibration is circumscribed to global reference values and does not circumvent problems that are inherent to the imaging modality...

OBJECTIVE The foramen arcuale (FA) is a bony bridge located over the vertebral artery on the posterior arch of the atlas. The presence of an FA can pose a risk during neurosurgery by providing a false impression of a broader posterior arch. The aim of this study was to provide the most comprehensive investigation on the prevalence of the FA and its clinically important anatomical features. METHODS Major electronic databases were searched to identify all studies that reported relevant data on the FA and the data were pooled into a meta-analysis...

Intracranial subdural hematoma developing following spinal anesthesia is a rare but serious complication. We describe a case of subdural hematoma developing following spinal anesthesia and diagnosed late. A female patient receiving spinal anesthesia for cesarean delivery 45 days prior to arrival at the emergency department presented to our hospital with non-severe headache persisting for 45 days after discharge. Computerized tomography (CT) of the brain performed due to long-term persisting headache resistant to medical treatment and a history of spinal intervention revealed a hypodense chronic subdural hematoma in the left frontoparietal area and a shift from left to right in midline structures...

BACKGROUND: Arterial calcification (AC) is frequent in patients with end stage renal disease and is also considered a risk factor for later morbidity and mortality. However, long-term factors associated with the process are not well known. We analyzed the trends over time of biomarkers related with development and progression of AC in incident patients on peritoneal dialysis (PD). METHODS: We performed a prospective study with 186 patients on PD followed up for 1 year...

Advanced neuroimaging techniques are increasingly being implemented in clinical practice as complementary tools to conventional imaging because they can provide crucial functional information about the pathophysiology of a variety of disorders. Therefore, it is important to understand the basic principles underlying them and their role in diagnosis and management. In this review, we will primarily focus on the basic principles and clinical applications of perfusion imaging, diffusion imaging, magnetic resonance spectroscopy, functional MRI, and dual-energy computerized tomography...

OBJECTIVE: Currently (18)F-2-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computerized tomography (PET/CT) is being successfully used for staging and follow-up of Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). Various studies have demonstrated that PET/CT effectively detects bone marrow involvement (BMI) and is concordant with bone marrow biopsy (BMB) findings, thus it is deemed as a complementary method. This study was aimed to evaluate(18)F-FDG-PET/CT efficiency for detection of BMI in HL and NHL...

The incidence of kidney cancer has increased in the majority of countries worldwide, and this disease has relatively high lethality. For many years, the Slovak Republic has been among the countries with the highest kidney cancer incidence, in particular in 2012 (according to global estimated values) in both genders, although mainly in females. In the last few years, the Czech Republic has had the highest incidence of kidney cancer worldwide. The use of imaging techniques such as ultrasound and computerized tomography has increased the detection of asymptomatic renal cell cancer...

"Amelogenesis imperfecta" (AI) describes a group of genetic conditions that result in defects in tooth enamel formation. Mutations in many genes are known to cause AI, including the gene encoding the serine protease, kallikrein related peptidase 4 (KLK4), expressed during the maturation stage of amelogenesis. In this study we report the fourth KLK4 mutation to be identified in autosomal recessively-inherited hypomaturation type AI, c.632delT, p.(L211Rfs(*)37) (NM_004917.4, NP_004908.4). This homozygous variant was identified in five Pakistani AI families and is predicted to result in a transcript with a premature stop codon that escapes nonsense mediated decay...

BACKGROUND: Recently there has been a large outbreak of Zika virus infections in Colombia, South America. The epidemic began in September 2015 and continued to April 2017, for the total number of Zika cases reported of 107,870. For those confirmed Zika cases, there were nearly 20,000 (18.5%) suspected to be pregnant women, resulting in 157 confirmed cases of microcephaly in newborns reported by their health government agency. There is a clear under-estimation of the total number of cases and in addition no prior publications have been published to demonstrate the clinical aspects of the Zika infection in Colombia...
