To determine whether phacoemulsification cataract surgery is an aerosol-generating medical procedure (AGMP) and therefore, to help determine the personal protective equipment required by healthcare providers in the era of the COVID-19 pandemic, as COVID-19 can be transmitted via aerosolization during AGMPs.

Laboratory DESIGN In this laboratory-based simulation, phacoemulsification cataract surgery was performed on porcine eyes. At a fixed distance, a DustTrak DRX Aerosol Monitor Model 8534 (DustTrak) was positioned to quantify particle generation during surgery. Experiments were run in triplicate for two wound sizes, 2.4 and 2.75mm. Positive controls were established by measuring particle generation from an aerosolizing spray-bottle. Negative controls were established while the phacoemulsification machine was not running.

The DustTrak was used to measure particulate matter (PM) mass fractions for each of three particle sizes, PM1, PM2.5, and PM4 (in microns), every 2 seconds during surgery and for one minute after. The main outcome measure was an increase in the mass fraction of aerosolized particles of various sizes.

There was no significant aerosolization of particles during cataract surgery for both the 2.4 and 2.75mm wound sizes.

Phacoemulsification cataract surgery was not found to be an AGMP. In the midst of the COVID-19 pandemic, ophthalmologists can continue to use droplet precautions while performing this surgery.

Cross-sectional, non-randomized, retrospective study.

Data of all patients waiting for cataract surgery were analysed at the beginning of May 2020, after two months without performing elective surgery. The waiting time since surgical inscription was considered an independent and overriding factor. Also, higher priority was given to patients with white or brunescent cataracts and patients with low visual acuity corrected distance visual acuity (CDVA) ≤20/200 in binocular patients or CDVA ≤20/63 in monocular patients. Criteria of medium priority included patients that remained with anisometropia and patients with glaucoma or low to moderate risk of chronic angle closure. Data of scheduled surgeries in the following months were then analyzed.

A total of 717 patients were waiting for phacoemulsification in our center. 191 patients (26.64%) had more than 4.5 months on the waiting list; the medium waiting time was 3.51±1.57 months. According to both priority criteria and waiting time, 48.6% (n=348) were categorized as priority cases. A total of 158 patients (22.0%) met the highest priority; 61 patients (8.5%) met the medium priority criteria. In 129 patients (18.0%), priority was considered based solely on higher waiting time. This algorithm allowed us to operate all priority cases within the first three months.

The presented protocol showed to be effective, providing a timely surgical opportunity for priority cases.

Neisseria (N.) gonorrhoeae infections are becoming increasingly resistant to recommended treatments. Resistance-guided therapy may mitigate the continued emergence of resistance by enabling the use of previously recommended treatments like ciprofloxacin.

To describe the effectiveness of ciprofloxacin to treat "susceptible" infections, we estimated the clinical efficacy of ciprofloxacin at various minimum inhibitory concentrations (MICs) and anatomic sites.

We reviewed publicly available reports using the PubMed.gov database and search terms "Gonorrhea/drug therapy"[Mesh] AND ciprofloxacin. We included clinical treatment studies in which ciprofloxacin was administered alone to treat N. gonorrhoeae, specimens were collected for N. gonorrhoeae culture from each infection, the MIC was determined for ≥ 90% of infective strains, and individual treatment outcomes were clearly defined. We recorded those data, ciprofloxacin dose and infection site. We calculated the frequency of treatment success and 95% confide in gonorrhea treatment. Clinicians can confidently use ciprofloxacin to treat susceptible gonococcal infections.
Data on testing rates and prevalence of and factors associated with of genital and extragenital chlamydia and gonorrhea among transgender women with HIV in the United States are limited.

This retrospective cohort analysis included transgender women living with HIV enrolled in the U.S. Centers for AIDS Research Network of Integrated Clinical Systems cohort between January 2005 and December 2016 with chlamydia or gonorrhea testing performed in HIV clinic. The primary outcome was a positive test for chlamydia or gonorrhea at urogenital or extragenital (rectal/pharyngeal) sites. Factors associated with infection were examined using logistic regression and generalized estimating equations to account for multiple tests per woman.

Among 312 transgender women in HIV care, 252 (81%) were tested for chlamydia or gonorrhea at least once. Annual testing rates were low 23%-53% at genital sites and 24%-47% at extragenital sites. A total of 88 infections were detected and 22% of women (55/252) had at least one positive test. Most infections occurred at extragenital sites (80% of chlamydia and 82% of gonorrhea positive tests). Factors associated with infection in an adjusted model were age 18-29 years compared to ≥50 years (aOR 7.6; 95% CI 1.8-31.2), CD4 count >350 compared to CD4 <200 (aOR 5.5; 95% CI 1.2-25.1) and higher engagement in HIV care (aOR 2.2; 95% CI 1.0-4.5).

Among transgender women living with HIV, testing rates for chlamydia and gonorrhea are inadequate, particularly at extragenital sites where most infections occur.

Trochlear dysplasia is a known risk factor for patellar dislocations yet normal trochlea development is not well described. This study will define the articular cartilage (AC) and subchondral trochlear morphology development in pediatric patients using magnetic resonance imaging (MRI) evaluation.

A retrospective knee MRI review included patients aged 3 to 16 years with nonpatellofemoral-related diagnoses. International classification of diseases-9/International classification of diseases-10 codes were used to identify eligible study patients. Measurements of the trochlea were made on the basis of previously established methods using the axial MRI just distal to the physis at the deepest portion of the trochlear groove. Three linear [lateral trochlear height (LTH), medial trochlear height (MTH), and central trochlear height (CTH)] and 3 angular [sulcus angle (SA), lateral trochlear slope (LTS), and medial trochlear slope (MTS)] were made at AC and subchondral bone (SCB). The 12 measurements were made indep no significant changes occurring thereafter.
This study found an increase in AC and SCB MTH, LTH, and CTH over time, as well as an increase in SCB LTS and MTS, with a decrease in SA. However, AC of the LTS and SA remained constant, with no significant change throughout growth. This normative data indicate that the LTS and SA of AC are predictors of final trochlea shape in normal development. Final trochlear morphologic development is nearly complete around age 12 years, with no significant changes occurring thereafter.
Deformity index (DI) and extrusion index (EI) are 2 radiographic methods currently used to quantify femoral head deformity in the active stages of Legg-Calvé-Perthes disease. This study aimed to quantify the interobserver reproducibility of the 2 methods using a large, international group of pediatric orthopaedic surgeons with diverse clinical experience.

Radiographs of patients (age 6 to 11 y at time of diagnosis) prospectively enrolled in an international multicenter-cohort study, were measured by members of our study group. For each radiograph, the raters independently assessed EI (n=33 cases) and DI (n=32 cases), along with the rater's subjective assessment of the extent of hip deformity (ie, none, mild, moderate, or severe). Reliability analysis was conducted using intraclass correlation coefficient (ICC) and κ techniques.

The ICC for EI on the affected side was 0.68 (95% confidence interval 0.57-0.79). The calculated DI ICC was 0.53 (95% confidence interval 0.41-0.68). Subjectively, an average of 68±3.5% of surgeons agreed on the subjective description of each patient's femoral head deformity.

EI is measured with a reasonably high rate of correlation among surgeons from disparate backgrounds. Agreement is lower among the same group of surgeons when the more complex DI is used. DI is most useful when utilized by a small number of experienced observers in a research setting, whereas EI may have better clinical applicability.

Factors that contribute to the development of juvenile osteochondritis dissecans (JOCD) of the talus are poorly understood. Some authors suggest that a higher loading of the affected zone may be a cofactor in osteochondral lesions. Therefore, the purpose of the study is to evaluate any association between ankle morphology and talus JOCD using morphologic parameters from magnetic resonance images. Our hypothesis is that ankles with JOCD lesions would have differences in the anatomy compared with age and sex-matched unaffected ankles.

We evaluated a total of 75 extremities. There were 22 patients (25 ankles) with talus JOCD lesions, and 50 patients (50 ankles) sex and age-matched individuals with healthy ankles served as controls. Two examiners conducted independent measurements of 8 magnetic resonance images parameters tibial anterior surface angle, tibial shaft both malleoli angle (TBM), tibial axis-medial malleolus angle, anterior opening angle of the talus, malleolar width, tibial lateral surface angle, Maximal tibial thickness, length of trochlea tali arc, and height of trochlea tali arc. Measurement reliability was assessed using intraclass correlation coefficients. Differences in parameters between JOCD patients and controls were evaluated using independent t test. The level of significance was taken to be P<0.05.

Intraclass correlation coefficients demonstrated good to excellent consistency for all measurements. Sagittal parameters demonstrated a significant length of trochlea tali arc increase in ankles with JOCD lesions compared with normal ankles (P=0.015). There was no statistical difference in any of the axial or coronal parameters.

Ankle morphology may have a relationship with JOCD lesions. Future larger studies will be useful for further clarifying our findings, and detecting other potential predisposing factors with clinical relevance and how they can be modified.
