BACKGROUND The correlation between the histologic grades and the apparent diffusion coefficient (ADC) in head and neck squamous cell carcinomas (HNSCCs) remains unclear. This study aimed to evaluate the potential of diffusion-weighted MRI (DW-MRI) at both standard and high b values to differentiate the histologic grades of HNSCC. METHODS In all, 54 consecutive patients with HNSCCs (34 well-di...

Background: Most data on laser resurfacing have come from studies of people with Fitzpatrick skin types 1 3; however, the world’s population is comprised mostly of Fitzpatrick skin types 4 6, which are more susceptible to post-inflammatory hyperpigmentation (PIH). Objective: For the purpose of expanding the expertise of plastic surgeons treating patients with darker skin types, this study exami...

This study utilized three-dimensional micro-computed tomography (micro-CT) to evaluate the regenerative response to Bio-Oss Collagen when used alone or in combination with a Bio-Gide bilayer collagen membrane for the treatment of four intrabony defects (5 to 7 mm) around single-rooted teeth. The micro-CT observations are compared to the clinical, radiographic, and histologic results, which have...

INTRODUCTION This study investigated the correlation between histologic predominant pattern and postrecurrence survival (PRS), and identified the clinicopathologic factors influencing PRS in patients with completely resected stage I lung adenocarcinoma. METHODS A total of 136 stage I lung adenocarcinoma patients who experienced tumor recurrence after completely resection were included in this...

It is unclear whether the different histologic subtypes of epithelial ovarian carcinoma have different risk factors. We investigated the relationships between selected epidemiologic variables (i.e., parity, family history of ovarian cancer, oral contraceptive use, a history of tubal ligation and noncontraceptive estrogen use) and the major histologic subtypes of epithelial ovarian cancer in a h...

INTRODUCTION Pulmonary arteriovenous malformations are a common cause of progressive cyanosis in children after cavopulmonary anastomoses. We analyzed the pulmonary histologic characteristics from children in whom pulmonary arteriovenous malformations developed after procedures that resulted in pulmonary arterial blood flow devoid of hepatic venous effluent. METHODS We performed routine histo...

BACKGROUND There are controversies about the importance of biopsies of normal colon mucosa in the investigation of patients with chronic diarrhea. STUDY Colonic and terminal ileum biopsies of 167 patients were reviewed. In 5 patients, used as controls, colonoscopy was done due to family history of colon cancer. RESULTS The 5 patients without symptoms had no histologic abnormalities. The his...

Age has been used as a prognostic factor for patients with peripheral neuroblastic tumours (pNTs). The latest analysis disclosed a cut-off around 18 months for the optimal prognostic distinction. The International Neuroblastoma Pathology Classification (INPC) distinguishes favourable and unfavourable histology based on the age-appropriate evaluation of histologic indicators (grade of neuroblast...

BACKGROUND/AIMS Ulcerative colitis (UC) patients are at greater risk for the development of colorectal neoplasia. Several individual studies have demonstrated associations between severity of histologic inflammation and colorectal neoplasia. However, a comprehensive systematic review has not been completed. We performed a systematic review and meta-analysis to explore the relationship between h...
