The combined influence of road and railway noise showed an increase of total annoyance.

The effects of environmental noise on sleep are of great interest to public health. Numerous studies have been conducted to investigate these effects; however, these previous studies applied existing sound-level statistics that were not based on neurophysiology.

This study aimed to develop a new night-time noise index based on neurophysiology and epidemiology.

First, we derived a formula for predicting the noise effects on sleep based on a neurophysiological model of brainstem sleep regulation, where awakening was associated with greater electrical potentials in the brainstem. Second, we investigated the noise effects on sleep using the results of an epidemiological study conducted in the vicinity of the Kadena military airfield in Okinawa, Japan. Thirty volunteers participated in the study. Vibrations of whole-body movements were recorded using sheet-shaped sleep monitors for 26 consecutive nights. The onset of motility, which was defined by monitor vibrations, was used to index awakening reactions.

Our statistical model could properly predict the fluctuating risk of motility onset. The new index, which is the mean of the sound level above 60 dB, can be successfully used, irrespective of the duration of noise exposure. Additionally, it out-performed existing event-related noise indices.

We derived a new night-time noise index for evaluating the noise effects on sleep. To our knowledge, this is the first study to explain the noise effects on sleep with the consideration of neurophysiology and epidemiology.

Given its rarity, we queried a national cohort over an 11-year period to study the temporal and demographic variations in presentation, evaluation, and management of patients with PF compared with a cohort of control patients. The National Inpatient Sample was queried between the years 2005 and 2016 for patients with a diagnosis of PF. Appendectomy patients were selected as a control cohort, given the non-discriminatory nature of this disease. Clinical and demographic data of the patients were compared with that of controls. Presenting symptoms, rates of surgical repair, and rates of associated surgical procedures were evaluated in the PF cohort. During the study period, 5802 patients were hospitalized for PF. The annual incidence of PF remained unchanged at 1.0-1.8 cases per 100 000 hospitalizations over the study period. Compared with the control cohort, PF patients were more likely to be younger (38.7 years vs 41.2 years, P ≤ 0.001), have lower rates of comorbidities except erectile dysfunction (1.4% vs 0.1%, P ≤ 0.001), and were more likely of Black race (25.4% vs 6.2%, P ≤ 0.001). Notably, PF patients had significantly higher rates of substance abuse (26.4% vs 18.1%, P ≤ 0.001), despite no difference in the diagnosed psychiatric disorders. PF rarely presented with hematuria (3.5%); however, urethral evaluation was performed in 23.1%, most commonly with cystoscopy (19.2%). PF occurs more commonly in a younger, healthier male population, and among minorities. Importantly, rates of substance abuse appear to be higher in the PF cohort compared with those of controls.Lack of investment for magnetic resonance (MR) fusion systems is an obstacle to deliver targeted prostate biopsies within the prostate cancer diagnostic pathway. We developed a coordinate-based method to support cognitive targeted prostate biopsies and then performed an audit on cancer detection and the location of lesions. In each patient, the prostate is considered as two separate hemiprostates, and each hemiprostate is divided into 4 × 4 × 4 units. Each unit is therefore defined by a three-dimensional coordinate. We prospectively applied our coordinates approach to target 106 prostatic lesions in 93 men. Among 45 (of 106; 42.5%) lesions positive for cancer, 27 lesions (60.0%) harbored clinically significant disease. PSA density was significantly higher in patients with proven cancer (median 0.264 ng ml-2) when compared to the noncancer group (median 0.145 ng ml-2; P = 0.003, Wilcoxon rank-sum test). learn more Lesions with Prostate Imaging-Reporting and Data System (PIRADS) score of 5 were found to have a cancer incidence of 65.2%, while PIRADS 4 and 3 lesions have a lower risk of cancer detection, as expected, at 37.3% and 31.3%, respectively. The probability of a lesion being cancerous in our series significantly decreases as we go from the "apex-to-base" dimension (odds ratio [OR] 2.62, 95% confidence interval [CI] 1.55-4.44, P = 0.00034). Our analysis also indicates that the probability of cancer decreases as the prostate volume increases (OR 1.03, 95% CI 1.01-1.05, P = 0.00327). Based on this feasibility study, the use of coordinates to guide cognitive targeted prostate biopsies warrants future validation study in additional centers.The inhibition of 5-α reductase type 2 (SRD5A2) by finasteride is commonly used for the management of urinary obstruction resulting from benign prostatic enlargement (BPE). Certain BPE patients showing no SRD5A2 protein expression are resistant to finasteride therapy. Our previous work showed that methylated cytosine-phosphate-guanine (CpG) islands in the SRD5A2 gene might account for the absence or reduction of SRD5A2 protein expression. Here, we found that the expression of the SRD5A2 protein was variable and that weak expression of the SRD5A2 protein (scored 0-100) occurred in 10.0% (4/40) of benign adult prostates. We showed that the expression of SRD5A2 was negatively correlated with DNA methyltransferase 1 (DNMT1) expression. In vitro SRD5A2-negative BPH-1 cells were resistant to finasteride treatment, and SRD5A2 was re-expressed in BPH-1 cells when SRD5A2 was demethylated by 5-Aza-2'-deoxycytidine (5-Aza-CdR) or N-phthalyl-L-tryptophan (RG108). Furthermore, we determined the exact methylation ratios of CpG dinucleotides in a CpG island of SRD5A2 through MassArray quantitative methylation analysis. Ten methylated CpG dinucleotides, including four CpG dinucleotides in the promoter and six CpG dinucleotides in the first exon, were found in a CpG island located from -400 bp to +600 bp in SRD5A2, which might lead to the silencing of SRD5A2 and the absence or reduction of SRD5A2 protein expression. Finasteride cannot exert a therapeutic effect on patients lacking SRD5A2, which may partially account for the resistance to finasteride observed in certain BPE patients.Foreign accent syndrome (FAS) is a rare, poorly understood speech disorder. It is characterized by the patient speaking their native language in a different accent foreign to both the speaker and the listener. A majority of previously reported cases have been described in patients with diagnosed organic brain damage and a handful of other psychiatric disorders. FAS was not the result of language experience in our index patient, and there is no history of the patient ever visiting the United States of America. This case is presented because it is the first-ever seen case in the environment.Ventral hernia is a common complication of abdominal surgeries, with the incidence of up to 20% in some series. Giant ventral hernia is that with a neck more than 10 cm wide. The loss of abdominal domain due to the shift of viscera into the hernia sac could lead to the complication after surgery. A 54-year-old female presented with a giant pedunculated ventral hernia. She had low tension mesh repair through a transverse suprapubic incision. The surgical repair of giant hernia with mesh has led to reduced complications. The sublay mesh repair method has further reduced the rate of underlay mesh recurrence.Sickle hemoglobin (HbS) formed by the point mutation in the genetic code of beta-globin chain leading to valine substituting glutamic acid at position 6 of the beta-chain. The resultant sickle cell disease (SCD) characterized by occlusion of microvasculature by red blood cells is associated with multiple organ pathologies. One of such complications is chronic leg ulcers. We report a case of chronic leg ulcer, in a known sickle cell anemia patient, which did not respond to the wound dressing methods at the hospital's disposal. The ulcer was successfully treated using standard operative procedure (S.O.P) in wound care, applying local honey, and use of blood transfusion. EA was a 20-year-old university undergraduate who was admitted to April 2019 in Central Hospital Benin City with chronic leg ulcer of 1 year duration. She was also anemic with hemoglobin concentration of 3.0 g/dl (packed cell volume 15%). The wound was dressed with local honey, and anemia corrected with blood transfusion using concentrated red cells lacking the HbS trait. There was a progressive improvement in the healing of the ulcer with total closure after 4 months of treatment. Maintenance and follow-up measures were instituted to prevent reoccurrence. This report showed that honey has remarkable properties in promoting wound healing. Its usage in combination with transfusion of HbA red blood cells to manage chronic leg ulcers in SCD patients is advocated. However, this calls for further studies and research.

Rouviere's sulcus is a 2-5 cm fissure on the liver between the right lobe and caudate process. The benefit of finding the Rouviere's sulcus during laparoscopic cholecystectomy is supported by the fact that the cystic duct and artery lay anterosuperior to the sulcus, and the common bile duct (CBD) lays below the level of the Rouviere's sulcus. Hence, it can serve as an extrabiliary anatomical reference point during laparoscopic cholecystectomy to identify the location of CBD.

This prospective observational study was carried out on 99 patients during a period of 1 year. During laparoscopic cholecystectomy, Rouviere's sulcus was identified after retracting the fundus of the gallbladder toward the right shoulder. Its morphology in terms of open type, close type, or scar-like shapes was recorded, and if the CBD outline could be visualized, then its relation with the Rouviere's sulcus was noted.

Among all 99 study patients, Rouviere's sulcus could be identified in 63 cases (63.63%), whereas it could not be seen in 36 cases (36.36%) (P < 0.007). It was of open type in 68.25% (43 cases), close type in 25.39% (16 cases), and scar like in 6.35% (4 cases) (P < 0.0001). The Rouviere's sulcus was found to be above the level of CBD line in 50 patients (79.36%) and at the same level in 11 patients (17.46%), and in two patients, (5.97%) CBD line could not be visualized.

Identification of Rouviere's sulcus during laparoscopic cholecystectomy can serve as an additional reference point to avoid major bile duct injury. In the era of laparoscopy, it can be better visualized after creating the pneumoperitoneum and retracting the fundus of the gallbladder.
