Central corneal thickness measurement permits an evaluation of physiological and pathological corneal changes. It allows for an intra-ocular pressure correction factor. Our purpose was to determine the mean central corneal thickness in children aged 0 to 72 months and to examine factors that might affect it.

This was a cross-sectional hospital study which took place from February to December 2019 in the ophthalmology service of YO University Medical Center. It included healthy eyes of children 0-72 months of age examined under general anesthesia. Ultrasonic pachymetry was used to measure the central corneal thickness. The studied variables were age, sex, CCT, corneal diameter, intraocular pressure, and cup/disc ratio.

One hundred and twenty-seven healthy eyes of 78 children 0-72 months of age were included. The mean age was 22 months. The overall mean CCT was 554.01±34.21μm. It was 556.58μm for children from 0 to 36 months of age and 536.12μm for subjects over 36 months. The mean CCT was 555.96±32.96μm in boys and 551.80±36.16μm in girls. In patients who underwent bilateral CCT measurement, the mean CCT was 554.74±35.67μm in the right eye and 549.76±24.08μm in the left eye. Lower IOP's were found in patients with thicker corneas (p=0.00).

The CCT values for black children over 36 months of age was similar to the CCT in black adults.

The CCT values for black children over 36 months of age was similar to the CCT in black adults.

To compare the peripapillary and optic nerve head vessel density (PP-ONH VD) between glaucoma patients (all, early, moderated, and advanced) and healthy subjects of Afro-Caribbean descent (AD) and European descent (ED).

This was a cross-sectional study. One eye was evaluated in 90 subjects, including 66 glaucoma patients and 24 healthy subjects, who underwent PP-ONH VD imaging using SPECTRALIS® Optical Coherence Tomography Angiography (OCT-A). We analysed the superficial vascular complex using the AngioTool version 0.6a software. The correlation between the PP-ONH VD and visual field mean deviation (MD) was evaluated using a scatter plot and Spearman's rho correlation coefficient.

Among the healthy subjects, the AD group had a lower superficial PP-ONH VD [43.29±3.25% (mean±standard deviation)] than the ED group (46.06±1.75%) (P=0.016). FF-10101 Overall, superficial PP-ONH VD did not show any significant differences between the total AD and ED glaucoma patients or in the subgroup analyses (early/moderate/advanced) (AD 32.73±6.70%, 37.11±5.72%, 32.48±5.73%, 27.76±4.74%, respectively; ED 33.94±6.89%, 38.52±3.82%, 35.56±4.18%; 27.65±6.31%, respectively) (P>0.05 for all). A strong, statistically significant correlation was established between vessel density and mean deviation among AD and ED glaucoma patients (r=0.709 and r=0.704, respectively) (P<0.001 for both).

This pilot study shows that healthy subjects of AD had lower peripapillary and optic nerve head superficial vessel density than healthy subjects of ED, but no significant differences were found between AD and ED glaucoma groups (all, early, moderate, or advanced).

This pilot study shows that healthy subjects of AD had lower peripapillary and optic nerve head superficial vessel density than healthy subjects of ED, but no significant differences were found between AD and ED glaucoma groups (all, early, moderate, or advanced).Contrast-enhanced ultrasound imaging allows vascular imaging in a variety of diseases. Radial modulation imaging is a contrast agent-specific imaging approach for improving microbubble detection at high imaging frequencies (≥7.5 MHz), with imaging depth limited to a few centimeters. To provide high-sensitivity contrast-enhanced ultrasound imaging at high penetration depths, a new radial modulation imaging strategy using a very low frequency (100 kHz) ultrasound modulation wave in combination with imaging pulses ≤5 MHz is proposed. Microbubbles driven at 100 kHz were imaged in 10 successive oscillation states by manipulating the pulse repetition frequency to unlock the frame rate from the number of oscillation states. Tissue background was suppressed using frequency domain radial modulation imaging (F-RMI) and singular value decomposition-based radial modulation imaging (S-RMI). One hundred-kilohertz modulation resulted in significantly higher microbubble signal magnitude (63-88 dB) at the modulation frequency relative to that without 100-kHz modulation (51-59 dB). F-RMI produced images with high contrast-to-tissue ratios (CTRs) of 15 to 22 dB in a stationary tissue phantom, while S-RMI further improved the CTR (19-26 dB). These CTR values were significantly higher than that of amplitude modulation pulse inversion images (11.9 dB). In the presence of tissue motion (1 and 10 mm/s), S-RMI produced high-contrast images with CTR up to 18 dB; however, F-RMI resulted in minimal contrast enhancement in the presence of tissue motion. Finally, in transcranial ultrasound imaging studies through a highly attenuating ex vivo cranial bone, CTR values with S-RMI were as high as 23 dB. The proposed technique demonstrates successful modulation of microbubble response at 100 kHz for the first time. The presented S-RMI low-frequency radial modulation imaging strategy represents the first demonstration of real-time (20 frames/s), high-penetration-depth radial modulation imaging for contrast-enhanced ultrasound imaging.This pilot clinical study evaluated primarily the efficacy of feeding vessel ablation (FVA) in the treatment of hepatocellular carcinoma (HCC) located at the liver marginal angle (LMA). link2 Nine patients with nine unresectable HCC lesions were prospectively included in this study. The target tumors (mean 3.0 cm, interquartile range 2.4-3.6 cm) were located at the LMA (segment 2/3/6) and adjacent to the gastrointestinal tract. Artificial ascites was attempted and failed. Multimode ultrasound technologies, including 2-D and real-time 3-D contrast-enhanced ultrasound, were used to identify the morphology and structure of the feeding vessels for the target tumors. During the treatment, a unipolar cool-tip electrode was used to ablate the feeding vessels, and the target ablation point was set in subsegmental or more distal vessels to induce a downstream ischemia region. Therapeutic outcomes were assessed after FVA, including the rates of technical success, tumor response, local tumor progression (LTP), overall survival (OS) and major complications. Cumulative LTP and OS were estimated with the Kaplan-Meier method. The technical success rate determined immediately after radiofrequency ablation was 7 of 9 (77.8%). Complete response (CR) was achieved in 7 of 7 tumors (100%) at the 1-mo evaluation. During a median follow-up period of 15.6 mo (range 4.3-53.3 mo), CR remained in 6 of 7 tumors (85.7%), with LTP observed in 1 of 7 tumors (14.3%) 4.7 mo after treatment. The cumulative 1-, 3- and 5-y LTP-free rates were all 83.3%, and the cumulative 1-, 3- and 5-y OS rates were 42.9%, 28.6% and 0%, respectively. No major complications occurred. We concluded that FVA can induce subsegmental devascularization and has the potential to serve as an effective and safe alternative technique for local control of unresectable HCC located at the LMA when artificial ascites fails.India is well known for the rampant growth of ESBLs that jeopardized the clinical utility of standalone beta-lactam. Pharmaceutical organizations fancied to rescue these beta-lactams by combining them with generic beta-lactamase inhibitors despite such combinations were never investigated in non-clinical or clinical studies. Lack of stringency in regulatory review practices allowed the market entry of these combinations. CSE 1034 (ceftriaxone, sulbactam and EDTA) and cefoperazone sulbactam are the most irrational antibiotics in clinical use. The effectiveness of such combinations relies on multiple factors such as relative beta-lactamase stability of the standalone beta-lactam, the inhibitory potency of the beta-lactamase inhibitor and more importantly the adequacy of the dose incorporated in the formulation. Unfortunately, none of the unconventional BL-BLI inhibitor combinations marketed in India has been subjected to such evaluations. Therefore, their therapeutic utility is uncertain. Besides questionable therapeutic utility, sub-optimal exposures would lead to the selection of resistant clones.

The aim of this multicenter study is to evaluate AYC.2.2 agar for the isolation of mycobacteria from clinical samples.

Totally 5559 media were tested in 7 centers. AYC.2.2 agar media for the study were prepared by C1 and sent to other centers under appropriate conditions. Other media except AYC.2.2 agar were purchased commercially. The media were subjected to routine laboratory operations in the center where they were sent. After the samples received for routine processing (in all centers, samples were processed with the same method (NALC-NaOH)), they were cultivated on routine media and AYC.2.2 agar afterward.

C1 Average growth time was determined as 12.74±3.74 days with MGIT 960 system; 24.42±4.75 days with LJ and 24.37±4.96 days with AYC.2.2 agar. C2 Average growth time was determined as 18.25±9.32 days with TK-Medium, 28.73±7.44 days with LJ, and 31.72±6.35 days with AYC.2.2 agar. C3 Average growth time was determined as 20.48±7.24 days with Ogawa medium, 20.74±7.12 days with LJ, and 20.26±7.43 daysosis and performing antibiotic susceptibility tests using AYC.2.2 agar before it can be used as a routine media in the laboratories.Here, we report on the remarkable survival of a simultaneous kidney-pancreas transplant recipient who has received minimal immunosuppression, has had normal kidney function, and has been insulin-free for 40 years since her transplant surgery.Despite the increase in deceased organ donation over the past ten years, the gap between patients awaiting transplant and available organs continues to widen. Deceased donors secondary to acute fatal poisonings represent less than 1% of all organ donors. Organs from poisoned donors have largely been discarded due to concerns of toxin transmission and poor organ function as well as the paucity of data that exists regarding this donor population. Here, we report a case of a 40-year-old male who underwent successful liver re-transplantation from a donor who died following ethylene glycol ingestion. To our knowledge this case report is the first to describe successful re-transplantation from an ethylene glycol-poisoned donor. link3 We also provide a comprehensive review of the literature describing organ donation from poisoned donors.

Despite ongoing efforts to decrease ionizing radiation exposure from computed tomography (CT) use in pediatric appendicitis, high CT utilization rates are still observed across many hospitals. This study aims to identify factors influencing CT use and facilitators and barriers to quality improvement efforts.

The Pediatric Surgery Quality Collaborative is a voluntary consortium of 42 children's hospitals participating in the National Surgical Quality Improvement Project - Pediatric. Hospitals were compared based on CT utilization from January 1, 2019, to December 31, 2019. Semi-structured interviews were conducted with surgeons, radiologists, emergency medicine physicians, and clinical data abstractors from 7 hospitals with low CT use rates (high performers) and 6 hospitals with high CT use rates (low performers). A mixed deductive and inductive coding approach for analysis of the interview transcripts was used to develop a codebook based on the Theoretical Domains Framework and subsequently identify prominent barriers and facilitators to CT reduction.
