AKAP9 supports spermatogenesis via the outcomes in microtubule as well as actin cytoskeletons inside the rat testis.
Also, histopathological features of acute inflammation were more prevalent in examined specimens from group B. CONCLUSION Several histopathological features of the examined bowel specimens in HD, other than presence or absence of ganglion cells, are indicative of postoperative functional outcome. These include the thickness and maturity of nerve bundles, in addition to the presence of histopathological features of acute inflammation. LEVEL OF EVIDENCE This is a case control study (level III evidence). BACKGROUND AND OBJECTIVE Aspiration pneumonia is a common and serious complication to gastroesophageal reflux disease (GERD) among neurologically impaired children. Medication of GERD does not effectively prevent aspiration pneumonia, and whether antireflux surgery with fundoplication is better in this respect is uncertain. The objective was to determine whether fundoplication prevents aspiration pneumonia among children with neurological impairment and GERD. METHODS This was a population-based cohort study from Denmark, Finland, Norway and Sweden, consisting of neurologically impaired children with GERD who underwent fundoplication. The risk of aspiration pneumonia before fundoplication (preoperative person-time) was compared with the risk after surgery (postoperative person-time). Multivariable Cox regression provided hazard ratios (HRs) with 95% confidence intervals (CIs). Except for confounding adjusted for by means of the "crossover like" design, the HRs were adjusted for age, sex, year of entry and respiratory diseases. RESULTS Among 578 patients (median age 3.5 years), the preoperative person-time was 956 years and the postoperative person-time was 3324 years. Fundoplication was associated with 56% decreased overall HR of aspiration pneumonia (HR 0.44, 95% CI 0.27-0.72), and the HRs decreased over time after surgery. The risk of other types of pneumonia than aspiration pneumonia was not clearly decreased after fundoplication (HR 0.79, 95% CI 0.59-1.08). The 30-day mortality rate was 0.7% and the complication rate was 3.6%. CONCLUSIONS Antireflux surgery decreases, but does not eliminate, the risk of aspiration pneumonia among neurologically impaired children with GERD. Fundoplication may be a treatment option when aspiration pneumonia is a recurrent problem in these children. TYPE OF STUDY Cohort study. selleck inhibitor LEVEL OF EVIDENCE Prognosis study-level I. OBJECTIVES Many studies of neonates have shown that renal pelvis ectasia is more common in boys. The aim of this study was to determine whether there are structural differences in the renal pelvis between male and female fetuses in the second trimester of gestation. MATERIAL AND METHODS We studied 34 renal pelvises obtained from 34 human fetuses (17 males and 17 females), ranging in age from 13 to 23 weeks postconception. The renal pelvis tissue was stained with Masson's trichrome to quantify connective and smooth muscle cells (SMC). The tissue also was fixed for scanning electron microscopy (SEM) in a modified Karnovsky solution. The images were captured with an Olympus BX51 microscope and Olympus DP70 camera. The stereological analysis was done with the Image-Pro and ImageJ programs, using a grid to determine volumetric densities (Vv). Means were statistically compared using simple linear correlation and the Mann-Whitney test (p less then 0.05). RESULTS Quantitative analysis indicated differences (p=0.0275)ation with the age. LEVEL OF EVIDENCE III. BACKGROUND Selectively resurfacing the patella based on a patient's risk of secondary patella resurfacing (SPR) may be the optimal strategy for primary total knee arthroplasty (TKA). However, exactly which factors increase the risk of SPR is unknown. Utilizing New Zealand Joint Registry data, we investigated the following (1) What patient and surgical factors are more prevalent among TKA patients who received SPR compared to those who did not? and (2) What is the difference in Oxford Knee Scores (OKS) between those who receive SPR and those who do not? METHODS Prevalence of various patient and surgical factors was compared between 197 non-resurfaced TKAs that proceeded to SPR and 31,399 that did not. Multivariate analysis was used to determine the odds ratio for each factor that differed between groups. Six-month postoperative OKS for each group was utilized for comparison. RESULTS Posterior-stabilized designs had an odds ratio of 1.86 (95% confidence interval [CI] 1.31-2.66; P = .001) when compared to cruciate-retaining designs. When compared to age less than 55, age >75 and age 65-74 had odds ratios of 0.27 (95% CI 0.16-0.46; P less then .001) and 0.44 (95% CI 0.28-0.69; P less then .001) respectively. Six-month OKS was lower among those who received SPR (37.27 vs 27.26; P less then .001). CONCLUSION Younger age, posterior-stabilized design, and a low 6-month OKS were associated with SPR. BACKGROUND Optimal perioperative fluid management has not been established in patients undergoing orthopedic surgical procedures. Our purpose was to investigate the effects of perioperative fluid management (ie, preoperative, intraoperative, and postoperative) on patients undergoing total knee arthroplasty (TKA). METHODS One hundred thirty patients who met inclusion criteria undergoing primary unilateral TKA were prospectively randomized into traditional (TFG) vs oral (OFG) perioperative fluid management groups. The primary outcome was change in body weight (BW). Secondary outcome measures included knee motion, leg girth, bioelectrical impendence, quadriceps activation, functional outcomes testing, Knee injury and Osteoarthritis Outcome Score JR, VR-12, laboratory values, vital signs, patient satisfaction, pain scores, and adverse events. RESULTS The TFG had increased BW the evening of surgery (7.0 ± 4.3 vs 3.0 ± 3.9, P less then .0001), postoperative day (POD) #1 (9.1 ± 4.3 vs 4.7 ± 3.9, P less then .0001), and POD #2 (6.2 ± 5.0 vs 4.4 ± 4.0, P = .032). Bioelectrical impedance showed less limb edema in the OFG (4.2 ± 29.7 vs 17.8 ± 30.3, P less then .0001) on POD #1. Urine specific gravity differences were seen preoperatively between groups (OFG, more hydrated, P = .002). Systolic blood pressure decrease from the baseline was greater in the OFG on arrival to the floor (19.4 ± 13.5 vs 10.6 ± 12.8, P less then .0001) and 8 (23.4 ± 13.3 vs 17.0 ± 12.9, P = .006) and 16 (25.8 ± 13.8 vs 25.8 ± 13.8, P = .046) hours after floor arrival. The TFG had more urine output on POD #1 (3369 mL ± 1343 mL vs 2435 mL ± 1151 mL, P less then .0001). The OFG were more likely to go home on POD #1 than the TFG (63 vs 56, P = .02). CONCLUSION Oral fluid intake with IVF restriction in the perioperative period after TKA may offer short-term benefits with swelling and BW fluctuations. The authors continue to limit perioperative IVFs and encourage patient initiated fluid intake.
