Candidemia is one of the leading causes of bloodstream infections in the pediatric intensive care unit (PICU). The aim of this study was to define characteristics and risk factors for candidemia in the PICU setting and propose a predictive model to identify the patients at risk.

This was a retrospective matched case-control study in the PICU during a 9-year period. Patients with candidemia were studied and matched with control patients without candidemia. Univariate analysis was performed for potential risk factors and multivariate analysis was conducted to determine the prediction score for candidemia.

Forty-two cases of candidemia were matched with 84 control patients. Candida parapsilosis was the most common (71.4%) species. CathepsinInhibitor1 Risk factors independently associated with candidemia were the use of >2 antibiotics in a maximum period of 4 weeks before the candidemia (odds ratio [OR] 10.59; 95% confidence interval [CI] 2.05-54.83), a previous bacterial infection in a maximum period of 4 weeks before the candidemia (OR 5.56; 95% CI 1.44-21.5) and the duration of PICU stay of >10 days (OR 4.22; 95% CI 1.02-17.41). The proposed predictive scoring system has a sensitivity of 95.24%, specificity of 76.12%, OR 64.0, 95% CI 14.2-288.6, the positive predictive value of 66.67% and the negative predictive value of 96.97%.

Previously reported risk factors for candidemia have been confirmed and some new have been detected. The presented scoring system can help identify patients who would benefit from prophylactic antifungal therapy.

The purpose of this study is to determine whether the Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) patients is able to predict fall, fracture, periprosthetic fracture, or dislocation risk after femoral neck fracture arthroplasty surgery.

Four hundred one patients who underwent hip arthroplasty surgery after a femoral neck fracture at one urban academic medical center were stratified into groups based on their risk scores assigned at femoral neck fracture presentation. The cohort was reviewed for the occurrence of postdischarge falls, secondary fractures, and prosthetic dislocations that resulted in a presentation to the emergency department (ED) after discharge from their hip fracture surgery. The incidence and timing of these complications after discharge were compared between the low-risk and high-risk groups.

The low-risk group included 201 patients, and the high-risk group included 200 patients. The high-risk group had significantly more postdischarge falls resulting in ED presentation (49 vs. 32, p = .035) that occurred significantly sooner (12.6 vs. 18.3 months, p = .034) after discharge.

The STTGMA model was able to successfully stratify patients who are at a higher risk of sustaining a fall after an arthroplasty procedure for a femoral neck fracture.

To quantify changes in manifest refractive error and mean keratometric power (Km) at 1 month and ≥12 months after Salzmann nodule excision.

Clinical practice.

Retrospective consecutive case series.

Changes in manifest refractive error (spherical-equivalent), Km, and best-corrected visual acuity (BCVA) were compared for 73 eyes of 58 patients who underwent Salzmann nodule excision. Eyes with ocular comorbidities were excluded. Comparisons between preoperative and postoperative measurements were made by using generalized estimating equation models.

Mean patient age was 66 years, and 68 patients (93%) were female. Spherical-equivalent manifest refractive error was -0.27 ± 2.66 D before nodule excision and became more myopic (-1.10 ± 2.78 D) at 1 month after nodule excision (n=69, p<0.001) with no change at 12 months (n=14, p=0.13). A myopic shift ≥0.5 D occurred in 65% of eyes and ≥1.0 D in 36% of eyes. Km increased from 42.7 ± 2.11 D before nodule excision to 44.2 ± 1.82 D at 1 month after excision (n=49, p<0.001). BCVA improved from 0.18 ± 0.15 logMAR (Snellen equivalent 20/30) before nodule excision to 0.05 ± 0.09 logMAR (20/22, n=69, p<0.001) at 1 month after excision with no change at 12 months (n=14, p=0.73).

In addition to known changes in cylinder, Salzmann nodule excision is associated with a myopic shift in most eyes caused by corneal steepening. Patients should be counseled about the likelihood of refractive changes, and cataract surgery should be deferred until refractive stability is achieved.

Current intraocular lens (IOL) explantation techniques are limited to cutting the optic and removing the pieces through a small incision, or folding single piece acrylic IOLs using a two-handed technique. Poor execution of IOL explantation can result in injury to intraocular structures, including the corneal endothelium and iris. The minimally invasive "cartridge pull-through technique" was invented, using a cartridge for IOL implantation and novel forceps optimized for secure grasping of the IOL for removal. This method involved less manipulation in the anterior chamber, thereby reducing the risks of complications such as corneal and iris injuries. A "dropped IOL" lying on the retinal surface can be extracted directly without lifting it onto the iris first. The cartridge-pull through technique offers a more streamlined and potentially safer approach for IOL explantation.

A limited number of studies have investigated the presence of ongoing disease activity independent of clinical relapses in neuromyelitis optica spectrum disorder (NMOSD), and data are conflicting. The objective of our study was to examine whether patients with aquaporin-4 (AQP4)-IgG seropositive NMOSD exhibit progressive retinal neuroaxonal loss, independently of optic neuritis (ON) attacks.

In this single-center, longitudinal study, 32 AQP4-IgG+ NMOSD patients and 48 healthy controls (HC) were followed with serial spectral-domain optical coherence tomography and visual acuity (VA) assessments. NMOSD patients with ON less than 6 months before baseline were excluded, whereas data from patients with ON during follow-up were censored at the last visit before ON. VA worsening was defined as a decrease in monocular letter acuity ≥5 letters for high-contrast VA and ≥7 letters for low-contrast VA. Analyses were performed with mixed-effects linear regression models adjusted for age, sex, and race.

The median fophy in AQP4-IgG+ NMOSD eyes unaffected by ON. These results support that subclinical involvement of the anterior visual pathway may occur in AQP4-IgG+ NMOSD.Performing injections with a bulking agent consisting of nonanimal stabilized hyaluronic acid and dextranomer is a well-tolerated and efficacious treatment for mild to moderate fecal incontinence. Here, we discuss a case of a patient with a history of a bulking procedure for fecal incontinence who presented to the obstetrics/gynecology clinic for evaluation of a new vaginal "cyst," which was excised. Histopathologic examination revealed migrated bulking agent within the excised specimen.Fumarate hydratase-deficient leiomyomas (dFH leiomyomas) often display atypical pathologic features yet exhibit a benign clinical course. Recent data suggest that dFH leiomyomas may be misclassified as smooth muscle tumors of uncertain malignant potential, a category that encompasses a heterogenous subgroup of uterine neoplasms with smooth muscle differentiation and atypical features that impart ambiguity regarding their expected clinical behavior. dFH leiomyomas can be seen in the context of hereditary leiomyomatosis and renal cell carcinoma syndrome or in the sporadic setting. In this retrospective study, we sought to examine the prevalence and clinicopathologic characteristics of dFH leiomyomas in 48 tumors previously diagnosed as smooth muscle tumors of uncertain malignant potential from 38 patients. Of these 48 tumors, 3 (6.3%) occurring in 2 patients were found to be deficient for FH by immunohistochemistry, including 1 uterine and 2 extrauterine (abdominopelvic) tumors. The 3 tumors showed histologic features typical of dFH leiomyomas, including hemangiopericytoma-like vessels, edema, macronucleoli, and atypia. Neither patient developed recurrent leiomyomas or renal cell carcinoma, and both were alive without disease at last follow-up. Our data suggest that dFH leiomyomas should be considered in the differential diagnosis of smooth muscle tumors of uncertain malignant potential, even in the context of extrauterine disease. Identification of FH deficiency in these tumors supports their classification as dFH leiomyomas despite their atypical morphologic features and/or clinical presentation. Importantly, detection of dFH in these cases may identify women at increased risk for hereditary leiomyomatosis and renal cell carcinoma who would benefit from genetic counseling and consideration for FH germline testing.In the female genital tract, rhabdomyosarcoma may occur in "pure" form or as a heterologous constituent of a biphasic neoplasm such as carcinosarcoma or adenosarcoma. Discriminating rhabdomyosarcoma from its histologic mimics relies on confirmation of skeletal muscle differentiation by morphology or immunohistochemistry (IHC), which can be challenging to interpret in some cases owing to limited expression. PAX7, a transcription factor expressed in mammalian muscle progenitor cells, has been reported in up to 86% of soft tissue rhabdomyosarcomas by IHC. To determine whether PAX7 IHC could augment current approaches to identify rhabdomyosarcoma in gynecologic malignancies, we assessed PAX7, myogenin, and MyoD1 IHC on whole tissue sections from 100 gynecologic tumors 50 with rhabdomyosarcomatous differentiation and 50 with features mimicking rhabdomyosarcoma. PAX7 expression was present in 96% (48/50) of gynecologic tumors with rhabdomyosarcomatous differentiation and was absent in all rhabdomyosarcoma mimics; it was more diffusely expressed than myogenin in 16 cases and was positive in a greater percentage of tumor cells in 28 cases.
