Abstract
OBJECTIVES To quantitatively describe the nature, severity, and duration of symptoms and functional impairment during recovery from transurethral resection of bladder tumors. MATERIALS AND METHODS All patients scheduled for transurethral resection were approached for enrollment in a text-message based ecological momentary symptom assessment platform. Nine patients reported outcomes were measured 7 days before surgery and on postoperative days 1, 2, 3, 5, 7, 10, and 14 using a 5-point Likert scale. Self-reported degree of hematuria was collected using a visual scale. Clinical data was collected via retrospective chart review. RESULTS A total of 159 patients were analyzed. Postoperative symptoms were overall mild, with the largest differences from baseline to postoperative day 1 seen in dysuria (median 0/5 vs. 3/5) and ability to work (median 5/5 vs. 4/5). Recovery was generally rapid, with 76% of patients reporting ≥4/5 agreement with the statement "I feel recovered from surgery" by postoperative day 2, although 15% of patients reported persistently lower levels of agreement on postoperative day 10 or 14. Patients undergoing larger resections (≥2cm) did take longer to return to baseline in multiple symptom domains, but the difference of medians vs. those undergoing smaller resections was less than 1 day across all domains. Multivariable analysis suggested that receiving perioperative intravesical chemotherapy was associated with longer time to recovery. 84% of patients reported clear yellow urine by postoperative day 3. CONCLUSION In this population, hematuria and negative effects on quality of life resulting from transurethral resection of bladder tumors were generally mild and short-lived, although a small number of patients experienced longer recoveries.

Abstract
PURPOSE We evaluated oncologic risks in a large cohort of patients with radiographic cystic renal masses who underwent active surveillance or intervention. MATERIALS AND METHODS A single-institutional database of 4,340 kidney lesions managed with either active surveillance or intervention between 2000-2020 was queried for radiographically cystic renal masses. Association of radiographic tumor characteristics and high-grade pathology was evaluated. RESULTS We identified 387 radiographically confirmed cystic lesions in 367 patients. Of these, 247 were resected (n=240) or ablated (n=7; n=247, 203 immediate vs 44 delayed intervention). Pathologically, 23% (n=56) demonstrated high-grade pathology. Cystic features were explicitly described by pathology in only 18% (n=33) of all lesions and in 7% (n=4) of high-grade lesions. Of the intervention cohort, African American race, male gender, and Bosniak score were associated with high-grade pathology (P < .05). On active surveillance (n=184), Bosniak IV lesions demonstrated faster growth rates than IIF and III lesions (2.7 vs 0.6 and 0.5 mm/y, P ≤ .001); however, growth rates were not associated with high-grade pathology (P = .5). No difference in cancer-specific survival was identified when comparing intervention vs active surveillance at 5 years (99% vs 100%, P = .2). No difference in recurrence was observed between immediate intervention vs delayed intervention (P > .9). CONCLUSIONS A disconnect between "cystic" designation on imaging and pathology exists for renal lesions. Over 80% of radiographic Bosniak cystic lesions are not described as "cystic" on pathology reports. More than 1 in 5 resected cystic renal lesions demonstrated high-grade disease. Despite this finding, judiciously managed active surveillance ± delayed intervention is a safe and effective management option for most radiographic cystic renal masses.

Abstract
Global warming poses detrimental effects on poultry production leading to substantial economic losses. The goal of our experiment was to test the hypothesis that heat stress (HS) would alter welfare and egg quality (EQ) of breeder ducks. Furthermore, we wanted to test if HS would increase cortisol levels in egg albumen. Adult Pekin ducks were randomly assigned to two different rooms at 85% lay with 60 hens and 20 drakes per room. Baseline data including body weight, body condition scores (BCS), and egg production/quality were collected the week preceding heat treatment. Ducks were subjected to cyclic HS of 35°C for 10h/day and 29.5°C for the remaining 14h/day for 3 weeks while the control room was maintained at 22°C. Eggs were collected daily and analyzed weekly for quality assessment, and for albumen glucocorticoid (GCs) levels using mass spectrometry. One week before the exposure to HS, 10 hens and 5 drakes were euthanized and the same number again after 3 weeks and birds necropsied. Data analyses were done by 1- or 2-way ANOVA as appropriate with a Tukey-Kramer post hoc test. BCS were analyzed using a chi-squared test. A p ≤ 0.05 was considered significant. Circulating levels of corticosterone were significantly (p < 0.01) elevated at week 1 only in the HS hens. The circulating levels of cortisol increased significantly at week 1 and 2 (p < 0.05), and week 3 (p < 0.01) in the hens and at weeks 2 and 3 only (p < 0.05) in the drakes. Feather quality scores (p < 0.01), feather cleanliness scores (p < 0.001) and footpad quality scores (p < 0.05) increased significantly in the HS group. HS elicited a significant (p < 0.001) decrease in egg production at weeks 1 and 3. Hens in the HS group showed significantly decreased BW (p < 0.001) and number of follicles (p < 0.05). Shell weight decreased significantly at week 1 only (p < 0.05) compared to controls. Yolk weight decreased significantly at week 3 (p < 0.01) compared to controls. HS elicited a significant increase in albumen cortisol levels at week 1 (p < 0.05) and week 3 (p < 0.05). Thus, cortisol may provide critical information to further understand and to improve welfare.

Abstract
OBJECTIVE This study sought to identify microRNA (miRNA) profiles of small, pathologically confirmed stage 1 clear cell renal cell carcinoma (ccRCC) tumors that are associated with progression to metachronous metastatic disease. MATERIALS AND METHODS Fifty-five pathologic stage 1 ccRCC tumors ≤5cm, from 2 institutions, were examined in a miRNA screening, followed by a validation study. For the screening phase 752 miRNA were evaluated on each sample to identify those with differential expression between tumors that subsequently did (n = 10) or did not (n = 10) progress to metastatic disease. For the validation, 35 additional samples (20 nonprogressors and 15 with distant progression) were utilized to investigate 20 miRNA to determine if a miRNA panel could differentiate aggressive tumors: associations of miRNA expression with cancer specific survival was also investigated. RESULTS In the screening analysis, 35 miRNA were differentially expressed (P < 0.05, FDR < 0.1) between the groups. In the validation, 11 miRNA were confirmed to have differential expression. The miRNA -10a-5p, -23b-3p, and -26a-5p differentiated nonprogressive and distant progressive disease with a sensitivity of 73.3% and a specificity of 85% (AUC=0.893). In addition, levels of miR-30a-3p and -145-5p were identified as independent prognostic factors of cancer specific survival. CONCLUSIONS This investigation identified miRNA biomarkers that may differentiate between non-progressive ccRCC tumors and those that progress to metastatic disease in this group of stage I tumors. The miRNA profiles determined in this study have the potential to identify patients with small renal masses who are likely to have progressive ccRCC. Such information may be valuable to incorporate into predictive models.

Abstract
Introduction: Volume of renal parenchymal loss is known to affect postoperative renal function after partial nephrectomy (PN). We utilize a novel comparison using donor nephrectomy (DN) patients to demonstrate the primary effect parenchymal volume loss plays on postoperative renal function following PN. Materials and Methods: Records of 250 living donor (DN) and 118 PN patients were retrospectively reviewed. Baseline characteristics and preoperative estimated glomerular filtration rate (eGFR)s were recorded. Percent changes in eGFR and incidences of surgically induced chronic kidney disease (CKD-S) in short, intermediate, and long-term postoperative periods were compared. Univariate and multivariate analyses of prognostic factors for development of CKD-S were performed. The PN group was further divided into subgroups with different lengths of warm ischemia time (WIT) and compared with DN patients. Results: At baseline, DN patients were younger, less likely to be male, had lower body mass index, lower American Society of Anesthesiologists, and higher preoperative eGFR (all p < 0.001). At hospital discharge, intermediate follow-up, and latest follow-up, renal function changes in DN and PN groups were -40.5% vs. -3.6%, -34.1% vs. -5.5%, and -33.2% vs. -4.4%, respectively (all p < 0.001). More DN than PN patients developed CKD-S (p < 0.001). DN was a significant risk factor for the development of chronic kidney disease on univariate and multivariate analyses (p < 0.001). On subgroup analysis, both subgroups with WIT 1 to 30 minutes and 31 to 60 minutes had less renal function decline at all time points compared with DN (p < 0.001). Conclusions: Volume of renal parenchyma retained is the dominant driver of postoperative renal function after nephrectomy, compared with all other factors. Surgeons should minimize parenchymal loss during PN to optimize postoperative renal function.

Abstract
In transgender surgery, the ideal neophallus is one that: (a) is constructed using a reproducible procedure, (b) possesses tactile and erogenous sensation, (c) is large and rigid enough (naturally, or using a prosthesis) to permit penetrative intercourse, (d) leaves acceptable donor site morbidity, (e) results in esthetically satisfactory appearance, and (f) allows for voiding while standing. The musculocutaneous latissimus dorsi (MLD) flap has favorable results in the area of neophalloplasty. Among its advantages are acceptable donor site appearance, stiffness sufficient for intercourse, and esthetically satisfactory genital appearance. The anatomy of the MLD flap supports the creation of a neophallus for transsexual anatomy revision. Herein, we give an overview of the advantages and disadvantages of the procedure, and the anatomical details and surgical steps involved. Novel illustrations were created from standard surgical text descriptions to clarify this topic for surgical training and patient understanding and decision making. A review of the relevant literature regarding the anatomy, procedure development, and outcomes is presented. The MLD flap uses part of the latissimus dorsi muscle with branches of the thoracodorsal vessels and nerve to construct a neophallus. A thin strip of muscle around the pedicle is harvested, resulting in a slightly curvilinear scar. The blood supply is connected to the femoral artery and saphenous vein or the deep inferior epigastric artery and vein, while the nerve is connected to the ilioinguinal nerve or the obturator nerve. The MLD flap for neophalloplasty is a reliable graft with a well concealed scar and low donor site morbidity. Clin. Anat. 31:152-159, 2018. © 2017 Wiley Periodicals, Inc.

Abstract
The origin of strong magnetic fields in the Universe can be explained by amplifying weak seed fields via turbulent motions on small spatial scales and subsequently transporting the magnetic energy to larger scales. This process is known as the turbulent dynamo and depends on the properties of turbulence, i.e., on the hydrodynamical Reynolds number and the compressibility of the gas, and on the magnetic diffusivity. While we know the growth rate of the magnetic energy in the linear regime, the saturation level, i.e., the ratio of magnetic energy to turbulent kinetic energy that can be reached, is not known from analytical calculations. In this paper we present a scale-dependent saturation model based on an effective turbulent resistivity which is determined by the turnover time scale of turbulent eddies and the magnetic energy density. The magnetic resistivity increases compared to the Spitzer value and the effective scale on which the magnetic energy spectrum is at its maximum moves to larger spatial scales. This process ends when the peak reaches a characteristic wave number k☆ which is determined by the critical magnetic Reynolds number. The saturation level of the dynamo also depends on the type of turbulence and differs for the limits of large and small magnetic Prandtl numbers Pm. With our model we find saturation levels between 43.8% and 1.3% for Pm≫1 and between 2.43% and 0.135% for Pm≪1, where the higher values refer to incompressible turbulence and the lower ones to highly compressible turbulence.

Abstract
OBJECTIVE To assess the prevalence of vulvovaginitis, enuresis and encopresis in children who were referred for allegations of sexual abuse. SUBJECTS A retrospective chart review of 1280 children presenting for non-acute examination after allegations of sexual abuse during a 15-year time span. Interview documentation, physical examination documentation, urinalysis, urine and vaginal cultures were reviewed. RESULTS Of the 1280 children, 73.3% were female and 26.7% male. The ages of the children ranged from 6 months to 18 years (median age was 6 years). Interviews revealed that fondling contact was the most common allegation, followed by oral, vaginal, and anal penetration. Interviews also disclosed lower urinary tract symptoms, UTI, constipation, encopresis and enuresis. Physical examination revealed no abnormal genital findings in 44.7% of cases. Examinations of the vagina noted: erythema (18.1%); hymenal notching (posterior 16.8%, anterior 4.4%); vuvlovaginitis (14.0%); laceration or transection (0.6%); and bruising (0.4%). Examination of the anus noted: anal fissure/tear (14.9%); loss of anal tone (10.6%); reflex anal dilatation (9.2%); venous congestion (3.8%); and proctitis (0.9%). Vulvovaginitis was noted in 14% (131/936) and encopresis in 2.3% (21/936). Enuresis according to age was reported in 13% of 5-9 year olds, 14.7% of 10-16 year olds and 18.2% of 17-18 year olds suspected of being abused. CONCLUSION Prevalence of vulvovaginitis and enuresis were increased, and encopresis was decreased in children with allegations of sexual abuse when compared to the general pediatric population. Physicians should continue to be aware of the possibility of the presence of these conditions in children who have been sexually abused, and offer appropriate treatment.

Abstract
We study the growth rate and saturation level of the turbulent dynamo in magnetohydrodynamical simulations of turbulence, driven with solenoidal (divergence-free) or compressive (curl-free) forcing. For models with Mach numbers ranging from 0.02 to 20, we find significantly different magnetic field geometries, amplification rates, and saturation levels, decreasing strongly at the transition from subsonic to supersonic flows, due to the development of shocks. Both extreme types of turbulent forcing drive the dynamo, but solenoidal forcing is more efficient, because it produces more vorticity.

Abstract
This study was conducted to evaluate the importance of intraoperative smear examinations for the final diagnosis of intracerebral stereotaxic procedures. 125 consecutive patients with suspect intracerebral lesions underwent stereotaxic frame-based biopsies after acquisition of computer tomographic and magnetic resonance images. After secondary image processing, including multiplanar visualization of the target region and target definition, a serial biopsy was realized using an aspiration Sedan needle. Biopsy taking was repeated as long as pathological tissue samples were obtained according to the visual impression of the neurosurgeon (group I) or to the first neuropathological result of a smear examination (group II). Retrospective analysis of all cases showed that intraoperative microscopic diagnostics could improve the conditions for a definitive neuropathological diagnosis from 91.8% (56/61 patients, group I) to 96.9% (62/64 patients, group II) (t>0.05). The number of biopsy specimens and the rate of CT-detectable small bleedings differed slightly between both groups and were higher in group II. The duration of surgery and anaesthesia as well as the final neurological outcomes were comparable in both groups. In conclusion, intraoperative smear examination as a kind of "bedside" diagnostics confers a better diagnostic safety and improves the reliability of this minimal invasive manoeuvre.

Abstract
37 consecutive patients with space-occupying intracerebral lesions were operated via frame-based stereotaxy. After CT-localizing of suspect lesions and computer-supported definition of entry and target coordinates a serial stereotactic biopsy was performed. Biopsy specimens allowed a satisfactory neuropathological examination and diagnostic result in 36 cases (97 %). Only three patients (8.1 %) showed an intraoperative bleeding, which was not associated with any postoperative CT-detectable hematoma, neurosurgical intervention nor with any neurological deficits. In summary we described the method of a computerized planning technique for stereotactic biopsy with the use of a special stereotactic planning program. High percentage of satisfactory neuropathological diagnoses and comfortable and accurate definition of target and entry coordinates justify computer support as a routine method.

Abstract
Data were collected on six large multigenerational pedigrees, four ascertained through a proband with major depression and two ascertained through a proband with a bipolar form of illness. Diagnoses were made using the SADS-L structured interview and Research Diagnostic Criteria (RDC). Complex segregation analyses were conducted on the bipolar and the major depression pedigree sets using a model allowing for both major locus and polygenic inheritance; in these analyses a variety of diagnostic schemes and assumptions concerning the lifetime population prevalence were examined. Linkage analyses on standard markers were conducted using parameters for transmission of susceptibility to illness derived from the segregation analyses. Results of the segregation analyses were quite sensitive to the diagnostic and prevalence assumptions. In the pedigrees ascertained through probands with a bipolar form of illness, we were unable to discriminate between major gene and polygenic inheritance. The data were compatible with Mendelian major gene transmission of susceptibility to illness when bipolar and schizoaffective manic diagnoses were considered as affected and the lifetime population prevalence was between 0.04 and 0.06. Outside this narrow prevalence range, or when additional diagnoses, such as major depression or hypomania, were included as expressions of liability to disease, major gene transmission of susceptibility to disease could be rejected. Similarly, in the pedigrees ascertained through probands with major depression, it was not generally possible to discriminate between major gene and polygenic transmission of susceptibility to illness. For a diagnostic scheme including only major depression as a manifestation of susceptibility to illness, there was a narrow range of lifetime population prevalence values (female prevalence ranging from 0.20 to 0.25, male prevalence set to 1/2 female prevalence) which yielded results compatible with major gene transmission. Linkage analyses for all markers yielded negative or inconclusive results. In one bipolar pedigree a lod score of 1.65 was found with a marker in chromosome 1 recommending further studies of this chromosome.
