Drusen are known to be the important hallmark to predict the development of age-related macular degeneration (AMD). The prevalence of drusen is lower in Asians compared with Caucasians so that the role of signs constituting early AMD is not well established in Asian populations as in Western countries. In this study, we retrospectively investigated clinical characteristics and 5-year incidence of neovascular AMD (nAMD) in the fellow eye of unilateral nAMD patients. Of 296 consecutive unilateral nAMD patients who had been followed up more than 5 years, 170 typical AMD, 119 polypoidal choroidal vasculopathy, and 7 retinal angiomatous proliferation were included. To examine factors associated with nAMD occurrence in the fellow eye, drusen and pigmentary abnormality in the fellow eye were classified into 4 categories; Category 1: no or small drusen < 63 μm (37.2%), Category 2: 63–125 μm medium drusen or pigmentary abnormality (22.2%), Category 3: large drusen > 125 μm (25.0%), Category P: pachydrusen (15.5%). The mean sub-foveal choroidal thickness (SFCT) was Category 1: 276 μm, Category 2: 308 μm, Category 3: 246 μm, and Category P: 302 μm, respectively. Of note, SFCT in Category 2 and Category P was significantly larger than those of Category 3. Finally, the 5-year incidence of nAMD in the fellow eye was 32/296 (10.8%); Category 1: 0/110 (0%), Category 2: 12/66 (18.2%), Category 3: 20/74 (27.0%), and Category P: 0/46 (0%). Thus, signs of intermediate AMD (large drusen) as well as those of early AMD, especially the pigmentary abnormality, may contribute to development of bilateral nAMD in Japanese patients.

Abstract Background Aesthetic treatment of the lower face is increasingly in demand, particularly owing to age-related changes in appearance. VYC-25L is a novel hyaluronic acid filler with high G′ and high cohesivity, specifically designed for sculpting and contouring of the chin and jaw. Objectives The aim of this study was to assess the use of a grid traced onto the chin and jaw for guiding treatment with VYC-25L. Methods This was a retrospective, single-center analysis of data from adult patients undergoing treatment of the lower third of the face with VYC-25L. A grid system of horizontal and vertical lines was used to systematize the process of treatment planning and performance. Results Thirty subjects were enrolled (53.3% female; mean [standard deviation] age, 34.4 [2.8] years). The mean quantity of VYC-25L used was 4.0 [0.8] mL. Based on the 5-point Global Aesthetic Improvement Scale, 29 patients (96.7%) rated their appearance at 20 days posttreatment as “much improved” or “very much improved.” The only complications recorded were early transient soft-tissue edema (n = 14; 46.7%) and bruising (n = 6; 20.0%). There were no cases of infection, paresthesia, asymmetry, hematoma, necrosis, or skin discoloration. Conclusions Treatment of the chin and jawline with VYC-25L, with injection locations determined by a standardized grid-based approach, appears to be effective and safe with high rates of patient satisfaction. Injection of this filler offers a potentially high-impact approach for patients across a variety of biological and economic circumstances. Level of Evidence: 4

Abstract. To investigate the role of gonadotropins in postnatal testicular activation, testosterone responsiveness to human chorionic gonadotropin was studied in 11 male infants (aged 5-180 days). The boys were given a single im injection of 5000 IU/1.7m2 hCG, and serum and salivary testosterone responses were then measured for 7 days. The results were compared with the serum testosterone responses of 8 older prepubertal boys (aged 1.7-10.4 years) studied with the same protocol. The mean (±sem) basal serum testosterone levels were 2.67±1.27 nmol/l in the infants and 0.09±0.02 nmol/l in the prepubertal boys (p<0.05). Both groups gave a significant response to hCG stimulation (p<0.001, ANOVA, one-way). The stimulated concentrations of serum testosterone were higher in the infants than in the prepubertal boys (p<0.001). The mean basal level of salivary testosterone was 30.5 ±7.0 and the mean maximal level was 97± 10.3 pmol/l in the infants (p<0.001). No age-related changes were observed in either basal or hCG-stimulated levels. In infants the mean (±sem) maximal hCG-stimulated increase was 25 ± 10-fold in serum and 8±4-fold in saliva (p=0.13). A clear stimulatory effect of hCG on testicular testosterone production was found, suggesting that the postnatal increase in serum testosterone concentration in male infants is gonadotropin-mediated. Salivary testosterone concentrations can be increased by hCG, indicating that measurements of salivary testosterone may provide an optional, non-invasive method for assessing gonadal function in children.

Objective The goal is to optimize the diagnosis of complications after thread implantation using high-resolution ultrasound (US).Material and Methods The study design included the formation of twelve sample comparison groups. Inclusion criteria for the group: women without evident somatic pathology after cosmetic implantation in various periods after the procedure. The difference between the groups was in the chemical composition of the material (L-lactic acid, polydiaxanone, copolymer of L-actide with ԑ-caprolactone, polypropylene, polyester fiber in a silicone sheath, metal), complaints (the presence of amyctic, the presence of overcorrection, the absence of complaints), the period of time after implantation (up to 6 months, from 6 to 12 months, more than a year). Then ultrasound was performed, 33 qualitative and 7 quantitative indicators were analyzed. The study involved 93 women aged 29 to 65 years after the thread implantation. The circulation period varied from 3 days to 20 years.Results An analysis of the relationship between quantitative and qualitative features revealed statistically significant connections between the presence of an acoustic shadow and threads of polylactic acid and polypropylene, the presence of reverberation, and the metal – gold (p < 0.0001). Relationships were established between polyester fibers in a silicone sheath with complaints of inflammation, the presence of edema during examination, perifocal edema around the thread during ultrasound (p < 0.0001). The difference was also found between the diameter of the thread in the group of patients examined up to 6 months and the group in the period 6–12 months after implantation (p < 0.0001), as well as the group up to 6 months and more than a year (p = 0.0033).Conclusion The presence of an acoustic shadow, a thread diameter of more than 1 mm are ultrasound signs of fibrotic changes around the thread. The characteristic echographic signs of inflammation around the thread will be a zone of reduced echoicity, corresponding to perifocal edema. Hypercorrection is a consequence of fibrotic changes development around the thread.

Appendicular Mass

Background: Appendicular mass consists of matted loops of bowel and omentum adherent to the adjacent inflamed appendix. Laparoscopic approach adds diagnostic value and allows visualization of entire abdominal viscera facilitating better and safer dissection.Methods: This is an observational prospective study done in patients presenting to Gandhi Hospital’s surgical department with incidentally detected appendicular mass on laparoscopy from August 2016 to August 2018.Results: Maximum cases belong to adolescent age group (13 out of 30). Majority of cases are male patients (24 out of 30). Each surgery took around 1 hour. No intraoperative complications occurred in 23 patients. Difficult adhesiolysis experienced in 5 patients. Serosal bowel injury occurred in 1 patient. Orals were delayed where intraoperative dissection was prolonged or difficult. Majority of patients were discharged after 3 days.Conclusions: With immediate operative management of appendicular mass presenting in early stages of inflammation, dissection can be safely proceeded with and appendicectomy can be safely performed eliminating the need for second hospitalization and risk of recurrence. The incidence of intra-operative and post-operative complications is low making laparoscopic appendicectomy in early appendicular mass a safe and feasible treatment option.

Typically, the position error of an eye-tracking device is measured as the distance of the eye-position from the target position in two-dimensional space (angular offset).  Accuracy is the mean angular offset.  The mean is a highly interpretable measure of central tendency if the underlying error distribution is unimodal and normal. However, in the context of an underlying multimodal distribution, the mean is less interpretable. We will present evidence that the majority of such distributions are multimodal.  Only 14.7% of fixation angular offset distributions  were  unimodal, and  of  these,  only  11.5%  were normally distributed.  (Of the entire dataset, 1.7% were unimodal and normal.)  This multimodality is true even if there is only a single, continuous tracking fixation segment per trial. We present several approaches to measure accuracy in the face of multimodality. We also address the role of fixation drift in partially explaining multimodality.

Effect Of Age

The role of metabolism in modifying age-related differential responses to asthma medications is insufficiently understood. The objective of this study was to determine the role of the metabolome in modifying the effect of age on bronchodilator response (BDR) in individuals with asthma. We used longitudinal measures of BDR and plasma metabolomic profiling in 565 children with asthma from the Childhood Asthma Management Program (CAMP) to identify age by metabolite interactions on BDR. The mean ages at the three studied time-points across 16 years of follow-up in CAMP were 8.8, 12.8, and 16.8 years; the mean BDRs were 11%, 9% and 8%, respectively. Of 501 identified metabolites, 39 (7.8%) demonstrated a significant interaction with age on BDR (p-value < 0.05). We were able to validate two significant interactions in 320 children with asthma from the Genetics of Asthma in Costa Rica Study; 2-hydroxyglutarate, a compound involved in butanoate metabolism (interaction; CAMP: β = −0.004, p = 1.8 × 10−4; GACRS: β = −0.015, p = 0.018), and a cholesterol ester; CE C18:1 (CAMP: β = 0.005, p = 0.006; GACRS: β = 0.023, p = 0.041) Five additional metabolites had a p-value < 0.1 in GACRS, including Gammaminobutyric acid (GABA), C16:0 CE, C20:4 CE, C18.0 CE and ribothymidine. These findings suggest Cholesterol esters and GABA may modify the estimated effect of age on bronchodilator response.

The purpose of this study is to explore whether shear wave elastography has diagnostic value in distinguishing benign and malignant thyroid imaging report and data system (TI-RADS) nodules, so as to provide more accurate information for clinical diagnosis and treatment of thyroid nodules. In this study, 134 patients with thyroid nodules who underwent ultrasound examination from February 2018 to October 2018 are collected. Firstly, according to the diagnostic criteria proposed by Horvath, TI-RADS grading is performed on them, and 78 patients with TI-RADS4 single solid nodules are screened out. Secondly, conventional ultrasound examination is performed on all the researchers, and shear wave elastographies are obtained 1 week after the examination. Thirdly, parameters of each lesion are measured by ultrasound physicians, and the maximum, minimum and average values of Young's modulus of each lesion are recorded. The results show that the mean and maximum of Young's modulus of benign lesions are (26.31 ± 9.88) kPa and (51.36 ± 14.51) kPa, respectively, the mean and maximum of Young's modulus of malignant lesions are (48.36 ± 16.53) and (69.15 ± 19.98) kPa, respectively, and the area under the ROC curve of Emean and Emax is 0.852 and 0.748, respectively. Therefore, shear wave elastography is a new type of ultrasound elastography, which has the advantages of objectivity and little influence from operators without artificial pressure. It has high sensitivity, specificity and accuracy in diagnosing benign and malignant thyroid nodules. Among them, the average value of Young's modulus has the greatest diagnostic value.

Цель работы - оценка изменений функционального состояния микроциркуляторного русла, изучение особенностей морфологических параметров кожи неинвазивными методами исследования при различных морфотипах старения. В исследовании приняли участие 55 человек 35-65 лет с инволюционными изменениями нижней трети лица. Выделены четыре морфотипа старения, в зависимости от которых пациенты были разделены на группы: 1-я - 19 пациенток с деформационным типом; 2-я - 17 пациенток с усталым; 3-я - 8 пациенток с мелкоморщинистым; 4-я - 11 пациенток со смешанным морфотипом. Для изучения состояния кожи использовали лазерную допплеровскую флоуметрию и УЗИ кожи (22 Mhz). Методом лазерной допплеровской флоуметрии выявлены достоверные изменения при сравнении показателей микроциркуляции и ультразвуковым методом исследования кожи - деформационного и мелкоморщинистого типов (p<0,05). У деформационного и смешанного типов наблюдали преимущественно атонический тип микроциркуляции (9,42±3,71 и 9,56±2,31 перф. ед. соответственно), а при мелкоморщинистом - спастический тип (7,86±1,6 перф. ед.), при усталом морфотипе показатель микроциркуляции был в пределах нормы (7,86±1,6 перф. ед.). Данные УЗИ кожи позволили выявить у пациенток с деформационным морфотипом старения наиболее высокие значения толщины эпидермиса (125,94±27,84 мкм), дермы (1 439±118,11 мкм), плотности дермы (12±2,59 у. е.) по сравнению с толщиной эпидермиса (85±22,01 мкм), толщиной дермы (1 130±68,55 мкм) и плотностью дермы (7,87±2,1 у. е.) при мелкоморщинистом морфотипе старения. The purpose of the work is to assess changes in the functional state of the microvasculature, study of the features of the morphological parameters of the skin by non-invasive research methods for various morphotypes of aging. The study involved 55 patients with involutional changes in the lower third of the face aged 35 to 65 years, included according with the inclusion and exclusion criteria. 4 morphotypes of aging were identified, depending on which patients were divided into corresponding groups: 1 - 19 patients with deformational type, 2 - 17 with tired type, 3 - 8 with fine wrinkled type, 4 - 11 with mixed morphotype of aging. To study the condition of the patients’ skin, laser Doppler flowmetry and ultrasound examination of the skin (22 Mhz) were used. The method of laser Doppler flowmetry revealed significant changes when comparing microcirculation indices and the ultrasound method for examining deformational and fine wrinkled type (p<0,05). In the deformational type and mixed type, a predominantly atonic type of microcirculation was observed (9,42±3,71 and 9,56±2,31 perf. u., respectively), and in fine wrinkled spastic type of microcirculation (7,86±1,6 perf. u.), in the oral morphotype the microcirculation index was within the normal range of 7,86±1,6 perf. u. The data of ultrasound examination of the skin made it possible to reveal in the deformational morphotype of aging high values of the thickness of the epidermis (125,94±27,84 μm), the dermis (1 439±118,11 μm) and the density of the dermis (12±2,59 a. u.) compared with the thickness of the epidermis 85±22,01 μm, the thickness of the dermis (1 130±68,55 μm) and the density of the dermis (7,87±2,1 c. u.) in the fine wrinkled morphotype of aging.
