Distribution and Positive Predictive Value of Follicle Stimulating Hormone Among Nonazoospermic Men.

PURPOSE: Our goal was to characterize the distribution of follicle stimulating hormone (FSH) in fertile and subfertile nonazoospermic men, and to determine the ability of various FSH thresholds to predict fertility status. MATERIALS AND METHODS: We performed a retrospective cohort study of 1389 nonazoospermic men who presented for fertility evaluation. Men with at least 2 semen analyses and 1 FSH level were included. Men were dichotomized into fertile and subfertile groups based on total motile sperm count. FSH was evaluated within a multivariable model, and positive predictive values (PPVs) for subfertility were used to assess the clinical utility of various FSH thresholds. RESULTS: One thousand fifteen (80%) men were classified as fertile and 274 (20%) as subfertile. Age, presence of varicocele, and testosterone levels were not statistically different between the groups. Median FSH was 4.0 vs 6.0 (P < .001) among fertile vs subfertile men. Multiple FSH thresholds ranging from 2.9 to 9.3 performed similarly in predicting fertility status (PPV 0.49-0.59). Only FSH thresholds above the 95th percentile (12.1) had PPVs greater than 0.7. The highest PPV (0.84) was seen at an FSH of 20.8 (99th percentile). CONCLUSIONS: While there were significant differences in FSH levels among fertile and subfertile nonazoospermic men, multiple FSH cutoffs between 2.2 and 9.3 performed poorly for prediction of fertility status as determined by total motile sperm count. It was not until the 95th percentile FSH value that a clinically useful level of predictability for subfertility was reached, indicating that FSH should not be used as a standalone test of fertility status. Nonetheless, FSH testing remains clinically useful and may be most informative in the setting of extreme values or discordant FSH and semen analysis results.

Hypogonadism, frailty, and postoperative outcomes among men undergoing radical nephrectomy.

BACKGROUND AND OBJECTIVE: Hypogonadism and frailty may impact postoperative outcomes for men undergoing radical nephrectomy (RN). We aimed to determine the prevalence of hypogonadism in men undergoing RN and whether hypogonadism and frailty are associated with adverse postoperative outcomes. METHODS: We identified men undergoing RN between 2012 and 2021 using the IBM Marketscan database. Frailty was determined using the Hospital Frailty Risk Score (HFRS). Patients were considered to have hypogonadism if diagnosed <5 years before RN. Length of stay (LOS), complications, emergency department (ED) visits, and readmissions were evaluated between men with and without hypogonadism at the time of surgery. Subgroup analysis of men with hypogonadism was performed to determine the effect of testosterone replacement therapy (TRT) on clinical outcomes. RESULTS: Among 13 598 men who underwent RN, 972 (7.1%) had hypogonadism. Men with hypogonadism were more frail compared to men without hypogonadism (HFRS: median: 8.2, interquartile range [IQR]: 5.2-11.7 vs. median: 7.0, IQR: 4.3-10.7, p < 0.001) and had increased incidence of postoperative ileus (13.0% vs. 10.8%, p = 0.045), acute kidney injury (25.5% vs. 21.6% p = 0.005), and cardiac arrest (1.2% vs. 0.6%, p = 0.034). Hypogonadism was not associated with LOS, 90-day ED visit or readmission. However, high-risk frailty was associated with increased risk of 90-day ED visit (hazard ratio [HR]: 2.1, 95% confidence interval [95% CI]: 1.9-2.4, p < 0.001) and 90-day inpatient readmission (HR: 2.6, 95% CI: 2.2-3.1, p < 0.001), compared to low-risk frailty patients. Among men with hypogonadism, TRT was not associated with any postoperative outcomes. CONCLUSIONS: Hypogonadism and frailty should be considered in the preoperative evaluation for men undergoing RN as risk factors for adverse postoperative outcomes.

Novel reference range values for serum testosterone: a cross-sectional study of 200,000 males.

PURPOSE: To better understand the effects of aging, metabolic syndrome, diurnal variation, and seasonal variation on serum testosterone levels in the context of current guideline statements on testosterone deficiency. METHODS: This cross-sectional study utilized the United Kingdom Biobank. Physical examination, anthropomorphic measurements, and laboratory evaluation were performed at the time of enrollment from 2006 to 2010. The primary outcomes were the effect of age, the presence of metabolic syndrome, the time of day, and the month of the year on serum testosterone levels. RESULTS: Among 197,883 included men, the 5th, 25th, 50th, 75th and 95th percentile testosterone levels in men without metabolic syndrome were significantly higher than those in men with metabolic syndrome at every decade of life (p < 0.001). The average testosterone level within each group (men without metabolic syndrome vs. men with) was clinically similar across decade of life (12.43 in 40's 12.29 in 50's 12.24 in 60's vs. 10.69 in 40's 10.56 in 50's 10.63 in 60's respectively). Average testosterone levels decreased with blood draws later in the day ranging from 10.91 to 12.74 nmol/L (p < 0.01). Similarly, there was seasonal variation in serum testosterone ranging from 11.86 to 12.18 nmol/L (p < 0.01). CONCLUSIONS: We found significant variation in serum testosterone according to the presence of metabolic syndrome and time of laboratory draw, but not according to age. These data challenge the prior dogma of age-related hypogonadism and favor an individualized approach towards serum testosterone measurement and interpretation. However, further studies are needed to correlate these population-based data with individuals' hypogonadal symptoms.

ALDH2 Expression, Alcohol Intake and Semen Parameters among East Asian Men.

PURPOSE: Inactivating mutations in mitochondrial aldehyde dehydrogenase 2 (ALDH2) are highly prevalent. The most common variant allele, ALDH2*2, is present in 40%-50% of East Asians, and causes acetaldehyde accumulation, flushing and tachycardia after alcohol intake. The relationship between alcohol intake and ALDH2 genotype on semen parameters remains unknown. MATERIALS AND METHODS: We conducted a cross-sectional study to determine the association between ALDH2 genotype, alcohol consumption and semen parameters among East Asian men. Volunteers completed a survey and submitted a semen sample for analysis. Participants were genotyped to determine ALDH2 status (ALDH2*1/*1, ALDH2*1/*2, ALDH2*2/*2), and immunohistochemical staining was used to determine protein expression of ALDH2 in spermatozoa. RESULTS: Of 112 men 45 (40.2%) were ALDH2*2 carriers. Among ALDH2*2 carriers, alcohol consumption was associated with significantly lower total sperm motility (median 20% [interquartile range 11%-42%] vs 43% [IQR 31%-57%], p=0.005) and progressive sperm motility (19% [IQR 11%-37%] vs 36% [IQR 25%-53%], p=0.008). Among alcohol consumers, ALDH2*2 carriers had significantly lower total sperm motility (20% [IQR 11%--42%] vs 41% [IQR 19%-57%], p=0.02), progressive sperm motility (19% [IQR 11%-37%] vs 37% [IQR 17%-50%], p=0.02) and total motile sperm count (28 million [M; IQR 9-79M] vs 71M [IQR 23-150M], p=0.05) compared to ALDH2*1/*1 individuals. Secondly, ALDH2 expression in human spermatozoa was significantly lower in ALDH2*2 carriers (ALDH2*1/*1 vs ALDH2*1/*2, p=0.01; ALDH2*1/*1 vs ALDH2*2/*2, p <0.001). CONCLUSIONS: Our findings suggest genotyping ALDH2, coupled with alcohol cessation counseling, may improve semen parameters among men.

Comparison of pulse-dose and high-dose corticosteroids with no corticosteroid treatment for COVID-19 pneumonia in the intensive care unit.

Corticosteroid dosing in the range of 0.5-2 mg/kg/day of methylprednisolone equivalents has become a standard part of the management of intensive care unit (ICU) patients with COVID-19 pneumonia based on positive results of randomized trials and a meta-analysis. Alongside such conventional dosing, administration of 1 gm of methylprednisolone daily (pulse dosing) has also been reported in the literature with claims of favorable outcomes. Comparisons between such disparate approaches to corticosteroids for Coronavirus disease 2019 (COVID-19) pneumonia are lacking. In this retrospective study of patients admitted to the ICU with COVID-19 pneumonia, we compared patients treated with 0.5-2 mg/kg/day in methylprednisolone equivalents (high-dose corticosteroids) and patients treated with 1 gm of methylprednisolone (pulse-dose corticosteroids) to those who did not receive any corticosteroids. The endpoints of interest were hospital mortality, ICU-free days at Day 28, and complications potentially attributable to corticosteroids. Pulse-dose corticosteroid therapy was associated with a significant increase in ICU-free days at Day 28 compared to no receipt: adjusted relative risk (aRR): 1.45 (95% confidence interval [CI]: 1.05-2.02; p = 0.03) and compared with high-dose corticosteroid administration (p = 0.003). Nonetheless, receipt of high-dose corticosteroids-but not of pulse-dose corticosteroids-significantly reduced the odds of hospital mortality compared to no receipt: adjusted Odds ratio (aOR) 0.31 (95% CI: 0.12-0.77; p = 0.01). High-dose corticosteroids reduced mortality compared to pulse-dose corticosteroids (p = 0.04). Pulse-dose corticosteroids-but not high-dose corticosteroids-significantly increased the odds of acute kidney injury requiring renal replacement therapy compared to no receipt: aOR 3.53 (95% CI: 1.27-9.82; p = 0.02). The odds of this complication were also significantly higher in the pulse-dose group when compared to the high-dose group (p = 0.05 for the comparison). In this single-center study, pulse-dose corticosteroid therapy for COVID-19 pneumonia in the ICU was associated with an increase in ICU-free days but failed to impact hospital mortality, perhaps because of its association with development of severe renal failure. In line with existing trial data, the effect of high-dose corticosteroids on mortality was favorable.

Testing delivery of components of cognitive behavioral therapy for insomnia to breast cancer survivors by smart speaker: a study protocol.

BACKGROUND: Insomnia is common in breast cancer survivors (BCS), affecting an estimated 30-50% of the 3.8 million BCS in the US. Insomnia is associated with health consequences for cardiometabolic and immune systems, neurobehavioral function, depression, fatigue, and quality of life and may put BCS at particular risk. While pharmacotherapy for insomnia may address symptoms in the short-term, cognitive behavioral therapy for insomnia (CBT-I) is considered the gold standard insomnia treatment. We describe our protocol to determine the efficacy of voice-activated delivery of CBT-I components on insomnia symptoms compared to a sleep education control among BCS. METHODS: We will conduct a 6-week, randomized controlled trial with two arms. Intervention arm participants will receive a smart speaker device and will be asked to engage with the program daily, using a voice-activated speaker with an accompanying smart-phone app. Control participants will have access to a website with basic information about CBT-I, sleep, and breast cancer survivorship and will be asked to engage with the website as desired. DISCUSSION: Our primary outcome is the Insomnia Severity Index total score. Secondary outcomes include sleep diary outcomes (sleep efficiency, wake after sleep onset, sleep onset latency, total sleep time, and sleep quality). This study will provide evidence on a promising modality to deliver elements of CBT-I for BCS experiencing insomnia. Trial Registration ClinicalTrials.gov NCT05233800 Released 3/25/2022.

Primary malignancies of the epididymis: clinical characteristics and prognostic factors.

INTRODUCTION We sought to describe clinical characteristics and identify prognostic factors among patients with primary malignancies of the epididymis (PMEs). MATERIALS AND METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (1975-2015) was queried to identify patients with PME. Descriptive statistics and multivariable Cox proportional hazards models were used. RESULTS: Eighty-nine patients with PME were identified. Median age was 57 years (5-85), and median overall survival (OS) was 16.8 years. The most commonly represented histologies were rhabdomyosarcoma (19.1%), B-cell lymphoma (16.9%), leiomyosarcoma (16.9%), and liposarcoma (12.4%). In multivariable analysis, tumor size ≥ 4 cm was associated with worse OS (HR = 4.46, p = 0.01) compared to tumors < 4 cm. Patients with nonsarcomatoid histology had OS similar to patients with sarcomatoid histology (HR = 0.95, p = 0.92). Disease with regional invasion (HR = 5.19, p = 0.007) and distant metastasis (HR = 29.80, p = 0.0002) had worse OS compared to localized disease. Receipt of radiotherapy was associated with enhanced OS (HR = 0.10, p = 0.006), whereas receipt of chemotherapy was not associated with OS. CONCLUSIONS: We describe the largest cohort of PMEs to date. Larger lesions and tumor stage were independently associated with poor overall survival, while receipt of radiotherapy was associated with enhanced overall survival.

Male and Female Sexual Dysfunction in Pediatric Cancer Survivors.

BACKGROUND: Pediatric cancer survivors suffer indirect long-term effects of their disease; however, there is a paucity of data regarding the effect of pediatric cancer survivorship on sexual function. AIM: To assess the prevalence and risk factors associated with sexual dysfunction among pediatric cancer survivors. METHODS: Pediatric cancer survivors were recruited to complete an online survey using the Female Sexual Function Index (FSFI) or the International Index of Erectile Function (IIEF-5), both validated questionnaires to assess female sexual dysfunction (FSD) and erectile dysfunction (ED). Patient demographics, oncologic history, prior treatment, and sexual habits were also queried. Logistic regression was used to evaluate risk factors for sexual dysfunction, and Mann-Whitney U test was used to identify factors associated with individual domains of the FSFI. OUTCOMES: The main outcome measures were FSFI and IIEF-5 score, which are used to diagnose FSD (FSFI<26.55) and ED (IIEF-5<22). RESULTS: A total of 21 (72.4%) female respondents and 20 (71.4%) male respondents were sexually active and completed the survey and FSFI or IIEF-5 questionnaire, respectively. Mean (±SD) age was 23.7 (4.1) years, and average age at diagnosis was 9.1 (5.0), with no difference between genders. Overall, 25.0% (5/20) of male and 52.4% (11/21) of female pediatric cancer survivors reported sexual dysfunction (P = .11). Oncologic history and prior treatment were not associated with sexual function. Females who reported difficulty relaxing during intercourse in the last 6 months had higher odds of reporting sexual dysfunction (odds ratio: 13.6, 95% confidence interval: 1.2-151.2, P = .03). Subgroup analysis of FSFI domains found that previous radiation therapy was correlated with decreased lubrication and satisfaction during intercourse, whereas previous treatment to the pelvic region significantly reduced satisfaction and increased pain during intercourse. CLINICAL IMPLICATIONS: Female pediatric cancer survivors have higher odds of reporting sexual dysfunction after treatment and should be screened appropriately to provide early intervention and to mitigate risk. STRENGTH & LIMITATIONS: Our study includes validated questionnaires to assess FSD and ED and queries specific characteristics to assess their association with sexual dysfunction. However, the study is limited by sample size and its cross-sectional survey design. CONCLUSIONS: The prevalence of female sexual dysfunction in this cohort is higher than that in the general population of equivalent-aged individuals, and clinicians should be aware of these potential long-term sequelae.

The Quality of Systematic Reviews and Meta-Analyses in Erectile Dysfunction Treatment and Management Published in the Sexual Medicine Literature.

INTRODUCTION: Erectile dysfunction (ED) is a common medical condition that requires high-quality evidence to guide clinical practice; however, systematic reviews (SRs) and meta-analyses (MAs) often vary in quality, raising concerns regarding the validity of their results. AIM: To perform an objective analysis of SRs and MAs in ED treatment and management and to report on the quality of published literature. METHODS: A comprehensive search in PubMed/MEDLINE and EMBASE of 12 high-impact urology journals was used to identify relevant publications. 2 authors independently performed searches, screened citations for eligibility, extracted data for analysis, and graded methodologic quality using A Measurement Tool to Assess Systematic Reviews (AMSTAR) criteria. MAIN OUTCOME MEASURES: The main outcome was AMSTAR score, which is a validated tool to evaluate the quality of SRs and MAs. RESULTS: 31 publications met inclusion criteria and were included in the analysis. The mean AMSTAR score (± SD) among all publications was 6.5 (±2.2) of 11, reflecting "fair to good" quality. 74.2% of systematic reviews and meta-analyses focused on pharmaceutical therapy for ED, with 51.6% studying the effect of phosphodiesterase-5 inhibitors. Only 1 SR/MA studied intracavernosal injection therapy and vacuum erection devices. No publications studied intraurethral injection therapy or implantable penile prostheses. Although not statistically significant, there has been a trend of increasing quality of SRs/MAs over time (P = .072). CLINICAL IMPLICATION: The methodologic quality of SRs/MAs should be assessed to ensure high-quality evidence for clinical practice guidelines in ED treatment and management. STRENGTH & LIMITATION: The data showed that methodologic quality of SRs/MAs in the treatment and management of ED is increasing over time. 12 high-impact urology journals were included in our search, which may introduce selection bias in our results. CONCLUSIONS: This review highlights a need for increased effort to study second- and third-line treatments for patients who fail oral therapy. Greenberg DR, Richardson MT, Tijerina JD, et al.

Genital Pain and Numbness and Female Sexual Dysfunction in Adult Bicyclists.

INTRODUCTION: Bicycle seat pressure on the perineum may impair arousal and clitoral erection, likely contributing to genital pain and numbness experienced by female cyclists. AIM: We aimed to identify the association between genital pain and numbness experienced by female cyclists and female sexual dysfunction (FSD). METHODS: Female cyclists were recruited to complete an online survey using the Female Sexual Function Index (FSFI), a validated questionnaire to assess FSD. Cyclist demographics, experience, preferred riding style, use of ergonomic cycle modifications, and genital discomfort while riding were also queried. Multivariate logistic regression analysis was used to evaluate risk factors of FSD. MAIN OUTCOME MEASURES: The main outcome was FSFI score, which is used to diagnose FSD when the FSFI score is <26.55. RESULTS: Of the survey respondents, 178 (53.1%) completed the survey and FSFI questionnaire. Mean age was 48.1 years (±0.8 standard error [SE]), and the average riding experience was 17.1 years (±0.9 SE). Overall, 53.9% of female cyclists had FSD, 58.1% reported genital numbness, and 69.1% reported genital pain. After adjusting for age, body mass index, relationship status, smoking history, comorbidities, and average time spent cycling per week, females who reported experiencing genital numbness half the time or more were more likely to have FSD (adjusted odds ratio [aOR], 6.0; 95% CI, 1.5-23.6; P = .01), especially if localized to the clitoris (aOR, 2.5; 95% CI, 1.2-5.5; P = .02). Females that reported genital pain half the time or more while cycling also were more likely to have FSD (aOR, 3.6; 95% CI, 1.2-11.1; P = .02). Cyclists experiencing genital pain within the first hour of their ride were more likely to have FSD (aOR, 12.6; 95% CI, 2.5-63.1; P = .002). Frequency and duration of cycling were not associated with FSD. Analysis of FSFI domains found that the frequency of numbness was correlated with decreased arousal, orgasm, and satisfaction during intercourse, whereas the frequency of pain significantly reduced arousal, orgasm, and genital lubrication. CLINICAL IMPLICATIONS: Female cyclists that experience numbness and/or pain have higher odds of reporting FSD. STRENGTHS & LIMITATIONS: Our study includes a validated questionnaire to assess FSD and queries specific characteristics and symptoms of genital pain and genital numbness; however, the study is limited by its cross-sectional survey design. CONCLUSION: This study highlights the need for cyclists to address genital pain and numbness experienced while cycling, and future studies are required to determine if alleviating these symptoms can reduce the impact of cycling on female sexual function.

Predicting Pathology From Imaging in Children Undergoing Resection of Congenital Lung Lesions.

BACKGROUND: Prenatal magnetic resonance imaging (MRI) is increasingly obtained to define congenital lung lesions (CLL) for surgical management. Postnatal, preoperative computed tomography (CT) provides further clarity at the cost of radiation. Depending on the lesion identified, the indication for resection remains controversial. We investigated the differences in detail found on prenatal MRI and postnatal CT compared with final pathology to determine their utility in preoperative decision-making. MATERIALS AND METHODS: All children undergoing resection of CLLs at a single institution between July 2009 and February 2018 were retrospectively identified. Their imaging, operative, and pathology reports were compared. All imaging studies were examined by pediatric radiologists with experience in prenatal CLL diagnosis. RESULTS: Fifty-five patients underwent CLL resection during the study period with 31 undergoing prenatal MRI, 45 postnatal CT, and 22 both. Resection was performed before 6 mo of age in 62% of patients. In the cohort undergoing both imaging studies, pathologic CLL diagnosis correlated with prenatal MRI and CT in 82% and 100% of patients, respectively (P = 0.13). Eight patients had systemic feeding vessels, of which 38% were identified on MRI, and 88% on CT (P = 0.13). Both studies had a specificity of 100% for detecting systemic feeding vessels. CONCLUSIONS: For children where prenatal MRI detected a systemic feeding vessel, CT was redundant for preoperative planning but had greater sensitivity. Ultimately, the CLL type predicted from postnatal CT was not significantly different from that predicted by prenatal MRI; however, both imaging modalities had some level of discrepancy with pathology.

Outcomes of Sacral Nerve Stimulation for Treatment of Refractory Overactive Bladder Among Octogenarians.

OBJECTIVE: Sacral nerve stimulation (SNS) is an effective treatment for refractory overactive bladder (OAB). However, advanced age is often cited as a reason to avoid SNS in the elderly. This study evaluates the safety and efficacy of SNS for refractory OAB among our octogenarian population. METHODS: A retrospective review from a single institution was performed on all SNS lead placements from December 1998 to June 2017 for refractory OAB. Octogenarians were characterized as 80 years of age or older at the time of Stage I. Efficacy and safety were determined by the rate of progression to Stage II, subsequent need for multimodal therapy, and rate of surgical revision and explantation. All patients were followed for a minimum of 12 months. RESULTS: Of 374 patients in this study, 37 (9.9%) were octogenarians. There was no difference in gender, race, smoking history, or prior OAB treatment regimens between cohorts. The rate of progression to Stage II was 56.8% for octogenarians compared to 60.5% for nonoctogenarians (p = 0.66). The rate of surgical revision, explantation, and need for multimodal therapy did not differ between groups. Subgroup analysis of octogenarians did not reveal any significant differences between successful and nonsuccessful Stage I patients. CONCLUSIONS: The safety and efficacy of SNS was similar between cohorts. This result suggests that SNS is a safe and effective therapy that should be considered among the treatment options for refractory OAB in octogenarian patients. Further studies are needed to determine predictive factors of Stage I success in elderly patients.

Anchoring effects on early autobiographical memories.

Studies of childhood memory typically show that our earliest memories come from between three and four years of age. This finding is not universal, however. The age estimate varies across cultures and is affected by social influences. Research from the judgments and decision-making literature suggests that these estimates might also involve a judgment under uncertainty. Therefore, they might be susceptible to less social influences such as heuristics and biases. To investigate this possibility, we conducted two experiments that used anchoring paradigms to influence participants' estimates of their age during early autobiographical memories. In Experiment 1, participants answered either a high-anchor or a low-anchor question, and were warned that the anchor was uninformative; they went on to estimate their age during their earliest autobiographical memory. In Experiment 2, we replicated Experiment 1 and extended the design to examine additional early autobiographical memories. In both experiments, participants in the low-anchor condition gave earlier age estimates than those in the high-anchor condition. These results provide new insights into the methods used to investigate autobiographical memory. Moreover, they show that reports of early autobiographical memories can be influenced by a relatively light touch - a change to a single digit in a single question.

Quality Measures in Orthopaedic Sports Medicine: A Systematic Review.

PURPOSE: To report the current quality measures that are applicable to orthopaedic sports medicine physicians. METHODS: Six databases were searched with a customized search term to identify quality measures relevant to orthopaedic sports medicine surgeons: MEDLINE/PubMed, EMBASE, the National Quality Forum (NQF) Quality Positioning System (QPS), the Agency for Healthcare Research and Quality (AHRQ) National Quality Measures Clearinghouse (NQMC), the Physician Quality Reporting System (PQRS) database, and the American Academy of Orthopaedic Surgeons (AAOS) website. Results were screened by 2 Board-certified orthopaedic surgeons with fellowship training in sports medicine and dichotomized based on sports medicine-specific or general orthopaedic (nonarthroplasty) categories. Hip and knee arthroplasty measures were excluded. Included quality measures were further categorized based on Donabedian's domains and the Center for Medicare and Medicaid (CMS) National Quality Strategy priorities. RESULTS: A total of 1,292 quality measures were screened and 66 unique quality measures were included. A total of 47 were sports medicine-specific and 19 related to the general practice of orthopaedics for a fellowship-trained sports medicine specialist. Nineteen (29%) quality measures were collected within PQRS, with 5 of them relating to sports medicine and 14 relating to general orthopaedics. AAOS Clinical Practice Guidelines (CPGs) comprised 40 (60%) of the included measures and were all within sports medicine. Five (8%) additional measures were collected within AHRQ and 2 (3%) within NQF. Most quality measures consist of process rather than outcome or structural measures. No measures addressing concussions were identified. CONCLUSIONS: There are many existing quality measures relating to the practice of orthopaedic sports medicine. Most quality measures are process measures described within PQRS or AAOS CPGs. CLINICAL RELEVANCE: Knowledge of quality measures are important as they may be used to improve care, are increasingly being used to determine physician reimbursement, and can inform future quality measure development efforts.

The role of visual imagery in autobiographical memory.

Visual imagery plays a fundamental role in autobiographical memory, but several aspects of this role remain unclear. We conducted three experiments to explore this relationship. In the first experiment, we examined the relation between the phenomenological properties of autobiographical memory and several measures of visual-imagery ability. We found no significant positive relation between imagery ability and autobiographical memory, except on a measure of cognitive style. In a second experiment, we examined the autobiographical memories of people with different cognitive styles-namely, visualizers and verbalizers. We found that, for both kinds of participant, visual imagery was correlated with the feeling that they were reliving their memories, but auditory imagery played a greater role in verbalizers. In a third experiment, we examined the memories of individuals who had a congenital absence of visual imagery. We found that they had a deficit of auditory imagery, as well; moreover, they were much less likely than controls to feel as though they were reliving their memories. The results support the idea that visual imagery plays a vital and irreplaceable role in autobiographical recall.

A 24-year-Old woman with recurrent pneumothoraces.

Lymphangioleiomyomatosis (LAM) is an abnormal proliferation of smooth muscle-like cells and may occur sporadically or in association with tuberous sclerosis complex. Patients are typically female, nonsmoking and may have cystic lung disease with pneumothorax. Diagnosis can be made by compatible imaging findings with a history of tuberous sclerosis complex, or in conjunction with vascular endothelial growth factor-D 800 pg/ml or greater, a highly specific finding. Sirolimus is first line treatment for LAM.
