We evaluated 581 patients with open-angle glaucoma (285 men and 296 women) and 595 individuals without glaucoma (273 men and 322 women). All of the participants underwent visual field testing using a Humphrey Visual Field Analyzer (30-2 program), an electrocardiogram (ECG), and blood pressure measurement.

Anatomy education for medical students in a virtual reality workspace: A pilot study.

The COVID-19 pandemic has posed a challenge for many medical schools, as they have had to adjust their curricula into an online format. This was particularly problematic for anatomy courses as in person dissections have historically been preferred for providing students with a three-dimensional learning environment. In this study, we aim to share our experience with conducting anatomy lectures for medical student using a virtual reality (VR) workspace.

Easy three-dimensional scanning technology for anatomy education using a free cellphone app.

The COVID-19 pandemic has brought difficult times to anatomy educators and medical/dental students. Under normal circumstances, gross anatomy classes give students opportunities to touch and observe human bones and cadaveric tissues, thus enhancing their understanding; such morphology is difficult to learn from textbooks alone. As many studies have shown, three-dimensional (3D) technologies used in online lectures can serve as alternatives to real specimens for providing knowledge of anatomy.

Visual Acuity in Glaucomatous Eyes Correlates Better with Visual Field Parameters than with OCT Parameters.

The visual acuity is very important for glaucoma patients in their lives. The purpose of this study was to examine about the correlation of visual acuity and visual field (VF) parameters or optical coherence tomography (OCT) parameters in patients with glaucoma. We evaluated 210 eyes of 210 patients (110 men and 100 women; mean age, 69.

A new option for education during surgical procedures and related clinical anatomy in a virtual reality workspace.

The COVID-19 pandemic and mandatory social distancing has brought challenges to anatomy educators who generally need in-person classes. The purpose of this study is to share the experience of a distant online lecture on a surgical procedure and related anatomy in a three-dimensional (3D) virtual reality (VR) workspace and to compare it with reported teaching methods, that is, an in-person class and a Zoom online class. The lecture was delivered by three authors of this article in a VR workspace that enables people to meet through VR.

Low placental growth factor levels and high soluble endoglin levels at 26-31 weeks of gestation precede light placenta with and without relatively heavy infant, respectively: A retrospective cohort study.

Aim: Our aim was to examine whether serum levels of placental growth factor (PlGF) and soluble endoglin (sEng) at 19-25 and 26-31 weeks of gestation were associated with the occurrence of the 9-block categorization of placenta weight (PW) and fetal/placenta ratio (F/P ratio).

Methods: We performed a retrospective cohort study in 1391 women with singleton pregnancy. Serum levels of PlGF and sEng were measured by enzyme immunosorbent assay.

[A Breast Stromal Sarcoma-Case Report and Literature Review].

A 83-year-old female presented with a painful, palpable mass of the breast, which had been growing rapidly for the past few months. The physical examination revealed a 5×5 cm, elastic, hard, mobile mass with a smooth surface in the right breast. Ultrasound confirmed a 6×4 cm hypoechoic mass with regular borders in the inferior lateral quadrant of the right breast, which required core-needle biopsy to establish diagnosis.

Difference in Z scores of placental weight and fetal/placental weight ratio by mode of delivery.

Aim: The difference of placental weight (PW) and fetal/placental weight ratio (F/P) Z scores by mode of delivery is unclear. To investigate such differences and the actual conditions underlying the imbalance between fetal and placental growth.

Methods: The data from Japanese database 2013 were assessed.

Glucose hypometabolism in the visual cortex proportional to disease severity in patients with essential blepharospasm.

Essential blepharospasm (EB) causes difficulty in eyelid opening because of involuntary movements of the orbicularis oculi muscle. Patients with EB have functional visual loss due to sustained eyelid closure. We examined cerebral glucose metabolism in 39 patients with EB (12 men and 27 women; mean age, 52.

Intrauterine Fetal and Neonatal Death between Small for Date and Non-Small for Date in Small for Gestational Age Infants.

To demonstrate the differences in intrauterine fetal deaths and neonatal deaths between small for date (SFD) and Non-SFD neonates by applying a novel classification from both Z scores of placental weight (PW) and fetal/placental weight ratio (F/P) to small for gestational age (SGA) neonates. From 93,034 placentas/infants of mothers who vaginally delivered a singleton infant (Japan Perinatal Registry Network database 2013), SGA (n=7,780) was chosen according to the reference to Japanese neonatal growth chart. They were divided into two subgroups: SFD (body weight and height less than the 10 percentile, n=3,379) and Non-SFD (only body weight less than the 10 percentile, n=4,401).

Treatment of asthma in smokers: A questionnaire survey in Japanese clinical practice.

Background: Cigarette smoking in patients with asthma leads to poor symptom control. As patients who are current smokers have been excluded from enrollment in many clinical trials on asthma, there are few reports on the treatment in current smokers with asthma. In this study, we aimed to assess how respiratory physicians manage asthma in current smokers in Japan.

Impact of placental weight and fetal/placental weight ratio Z score on fetal growth and the perinatal outcome.

To classify the infants into 9 blocks based on the deviation of both placental weight (PW) and fetal/placental weight ratio (F/P) Z score and compared the incident rate of perinatal death in each of the small for date (SFD) vs. appropriate for date (AFD) vs. heavy for date (HFD) groups.

Adrenal Rest Tumor of the Liver Preoperatively Diagnosed as Hepatocellular Carcinoma.

Background: Hepatic adrenal rest tumors are rare and show similar findings to hepatocellular carcinoma (HCC). It is difficult to distinguish an adrenal rest tumor from HCC due to radiological similarity. We report a case of an adrenal rest tumor in the liver that mimicked HCC radiologically.
