The effects of delivery type and gender on intraocular pressure and central corneal thickness in newborns

ABSTRACT Purpose: To analyze intraocular pressure (IOP) and central corneal thickness (CCT) in newborns during the first 12 h of life. Methods: Forty-three newborns born by vaginal delivery (VD) and 30 newborns born by cesarean section (CS) were evaluated. IOP and CCT were measured using Tono-Pen and handheld pachymeter, respectively, at both the 5th minute after delivery and at the 12th h of life. Results: The mean IOP for the VD group was significantly higher than that of the CS group at both the 5th minute and 12th h (p =0.042 and p =0.018, respectively). In both groups, the IOP decreased by the 12th h, but the decrease was only significant for the CS group (p =0.020). The decrease in CCT over the 12 h was significant for both groups (p <0.001). In the VD and CS groups, the IOP values of the males were significantly higher than those of the females at the fifth minute only (p =0.024 and p =0.043, respectively). No other values were significantly different between the genders. Conclusions: Newborn IOP is affected by the mode of delivery and gender. A higher IOP was found in vaginally delivered newborns than in CS newborns for at least 12 h postpartum. CCT showed a significant decline within 12 h. Male newborns have significantly higher IOP values in the first minutes of life

Comparison of CT and integrated PET-CT based radiation therapy planning in patients with malignant pleural mesothelioma

<p>Abstract</p> <p>Background</p> <p>When combined with adequate tumoricidal doses, accurate target volume delineation remains to be the one of the most important predictive factors for radiotherapy (RT) success in locally advanced or medically inoperable malignant pleural mesothelioma (MPM) patients. Recently, 18-fluorodeoxyglucose positron emission tomography (PET) has demonstrated significant improvements in diagnosis and accurate staging of MPM. However, role of additional PET data has not been studied in RT planning (RTP) of patients with inoperable MPM or in those who refuse surgery. Therefore, we planned to compare CT with co-registered PET-CT as the basis for delineating target volumes in these patients group.</p> <p>Methods</p> <p>Retrospectively, the CT and co-registered PET-CT data of 13 patients with histologically proven MPM were utilized to delineate target volumes separately. For each patient, target volumes (gross tumor volume [GTV], clinical target volume [CTV], and planning target volume [PTV]) were defined using the CT and PET-CT fusion data sets. The PTV was measured in two ways: PTV1 was CTV plus a 1-cm margin, and PTV2 was GTV plus a 1-cm margin. We analyzed differences in target volumes.</p> <p>Results</p> <p>In 12 of 13 patients, compared to CT-based delineation, PET-CT-based delineation resulted in a statistically significant decrease in the mean GTV, CTV, PTV1, and PTV2. In these 12 patients, mean GTV decreased by 47.1% ± 28.4%, mean CTV decreased by 38.7% ± 24.7%, mean PTV1 decreased by 31.1% ± 23.1%, and mean PTV2 decreased by 40.0% ± 24.0%. In 4 of 13 patients, hilar lymph nodes were identified by PET-CT that was not identified by CT alone, changing the nodal status of tumor staging in those patients.</p> <p>Conclusion</p> <p>This study demonstrated the usefulness of PET-CT-based target volume delineation in patients with MPM. Co-registration of PET and CT information reduces the likelihood of geographic misses, and additionally, significant reductions observed in target volumes may potentially allow escalation of RT dose beyond conventional limits potential clinical benefits in tumor control rates, which needs to be tested in future studies.</p

Use of knee height for the estimation of stature in elderly Turkish people and their relationship with cardiometabolic risk factors

The determination of the approximately truest value in height measurement is important in many fields, but it is difficult to perform true measurements, especially in the elderly individuals. We planned to investigate the following items in geriatric Turkish population: to calculate the decrease in height with advancing age by using the standing height measurement and estimated height derived from the knee height; to evaluate the significance of difference between the two measurement methods in the calculation of body mass index (BMI) and waist/height ratio (WHtR); to determine the cut-off value of WHtR according to estimated height in elderly individuals. We studied 551 cases aged between 19 and 97 years. Knee height was measured using a sliding caliper in a sitting position. Linear regression analysis was carried out to derive predictive equations for the estimation of stature with adults ( 60 years (mean: 69.51 +/- 7.12). Estimated BMI (EBMI) measurements in the females and males > 60 years were in average 1.23 kg/m(2) and 0.92 kg/m(2) higher than their real BMIs, respectively. EBMI measurements in the females 60 years, as compared to our estimated WHtR (EWHtR) measurements (p 60 years in our study, respectively. WHtR seemed to be a better anthropometric index that could predict most cardiometabolic risk factors in our study. EWHtR emerged to be a better cardiometabolic risk index especially in the elderly group. Crown Copyright (C) 2010 Published by Elsevier Ireland Ltd. All rights reserved

A geriatric patient with diffuse idiopathic skeletal hyperostosis

The most frequent health problems seen in senility are chronic and degenerative diseases. A 75-year-old male patient with the complaints of weight loss and difficulty in swallowing was admitted to our hospital from a nursing home. Upper system fiber-optic gastrointestinal endoscopy was performed and a mass at the junction of the hypopharynx and esophagus just below recessus piriformis obstructing almost the whole of the lumen and blocking the distal passage was detected. Computed tomography revealed marked narrowing secondary to osseous hypertrophy in the air column of the hypopharynx and proximal esophagus. Diffuse idiopathic skeletal hyperostosis or Forestier’s disease is an idiopathic disease characterized by the ossification of the anterior longitudinal ligament of vertebra and some of the extraspinal ligaments. In the present case we aim to discuss an elderly patient who suffered from dysphagia and weight loss and the diagnostic stages

Current perspective on diabetes mellitus in clinical sciences

Diabetes Mellitus (DM) receives significant attention from most scientists due to being a major global public health threat. Diabetes is considered one of the leading causes of death due to its micro and macrovascular complications. This insidious killer is estimated to reach a staggering number of 578 million (700 million by 2045) cases by 2030. In this book, utilizing the disciplines of clinical sciences, various contemporary topics related to diabetes are extensively discussed. These include the classification of diabetes, underlying causes, epidemiology, pathogenesis, impact on sexual functions, association with cancer, clinical manifestations, diagnostic methods, complications, and treatment options. Furthermore, intriguing and current subjects such as "antidiabetic phytotherapy" and "the relationship between oral health and diabetes" are also covered. By doing so, readers will acquire comprehensive and detailed knowledge about the clinical management of diabetes. Thus, this book not only serves those who seek to understand the scientific aspects of diabetes but also proves to be a valuable resource for healthcare professionals, researchers, and students in a clinical setting. We believe that this book will contribute to understanding the complexity of diabetes and provide beneficial solutions while shedding light on future studies
