The study suggests that changes in planning-related sensorimotor CNS regions may explain difficulties with force exertion and motor control in CRPS.Perspective Functional changes in motor planning-related brain regions might indicate that feedback-enhanced functional motor training may be effective for CRPS rehabilitation.Crooke cell change was first found in the regressed and suppressed corticotroph (adrenocorticotropic hormone-producing) cells, and now is known to occur in pituitary tumors. The tumor cells of this type can be recognized by morphology with immunohistochemistry, and are well known to predict aggressive behavior such as invasion and rare metastases. This is one of the representative neuroendocrine tumors in the pituitary which is now considered to have malignant potential as proposed in the pancreas and gastrointestinal tracts. It is important to emphasize the pituitary tumor pathology such as Crooke cell change for prognostication and appropriate therapies. This review article describes the evolution from the Crooke cells to Crooke cell tumors which is timely along with the Fifth WHO classification 2022 published online.Few reports assessed endothelial activation biomarkers in kidney allograft biopsies using immunohistochemistry. This retrospective cohort study evaluated the association between posttransplant outcomes and the immunohistochemistry expression of Caveolin-1, Von Willebrand Factor (Vwf), and T-Cadherin in for-cause biopsies diagnosed as interstitial fibrosis and tubular atrophy of unknown etiology. Samples with antibody-mediated changes were excluded. The patients were followed for 3 years after the biopsy or until graft loss/death. Seventy-one (71) samples from 66 patients were included. Eighteen (25.4%) patients lost their grafts, mainly due to chronic rejection (33.3%). Caveolin-1 and T-Cadherin were not associated with graft loss. Vwf had good accuracy in predicting graft failure (AUC 0.637, 95% CI 0.486 to 0.788 P =0.101). The presence of more than 10% of Vwf positivity in the microvasculature (Vwf >10%) was associated with reduced death-censored graft survival (58.2% vs. 85.4% P =0.006), and this result was also observed in the subgroup presenting mild interstitial fibrosis (ci=1) (65.7% vs. 88.6% P =0.033). The multivariate analysis showed that Vwf >10% was an independent risk factor for graft loss (HR=2.88, 95% CI 1.03 to 8.02 P =0.043). In conclusion, Vwf might be an additional tool to predict allograft outcomes in kidney transplant recipients with interstitial fibrosis and tubular atrophy of unknown etiology, probably reflecting immune endothelial activation.Invasive breast carcinomas are routinely tested for HER2 using immunohistochemistry (IHC), with reflex in situ hybridization (ISH) for those scored as equivocal (2+). ISH testing is expensive, time-consuming, and not universally available. In this study, we trained a deep learning algorithm to directly predict HER2 gene amplification status from HER2 2+ IHC slides. Data included 115 consecutive cases of invasive breast carcinoma scored as 2+ by IHC that had follow-up HER2 ISH testing. An external validation data set was created from 36 HER2 IHC slides prepared at an outside institution. All internal IHC slides were digitized and divided into training (80%), and test (20%) sets with 5-fold cross-validation. Small patches (256×256 pixels) were randomly extracted and used to train convolutional neural networks with EfficientNet B0 architecture using a transfer learning approach. Predictions for slides in the test set were made on individual patches, and these predictions were aggregated to generate an overall prediction for each slide. This resulted in a receiver operating characteristic area under the curve of 0.83 with an overall accuracy of 79% (sensitivity=0.70, specificity=0.82). Analysis of external validation slides resulted in a receiver operating characteristic area under the curve of 0.79 with an overall accuracy of 81% (sensitivity=0.50, specificity=0.82). Although the sensitivity and specificity are not high enough to negate the need for reflexive ISH testing entirely, this approach may be useful for triaging cases more likely to be HER2 positive and initiating treatment planning in centers where HER2 ISH testing is not readily available.Endometrial cancer (EC) is the most common gynecologic cancer and the current methods for the prediction of its prognosis and treatment response are unfortunately suboptimal. In this study, we evaluated the prognostic value of p53, Pirh2, and L1CAM in 60 cases of EC using immunohistochemistry (IHC) and polymerase chain reaction. TP53 missense mutations result in nuclear accumulation of p53 protein that can be detected as overexpression by IHC. This is in the form of diffuse strong nuclear positivity involving at least at least >50% of the tumor cells as a whole or if >50% of the tumor cells of a discrete geographical areas. Abnormal p53 IHC expression was expressed in 33.3% of the cases and significantly associated with the tumor grade, myometrial invasion (MI), lymphovascular invasion (LVSI), nodal metastasis, and FIGO stage, and the advanced European Society for Medical Oncology (ESMO) risk groups ( P less then 0.001 for each). High IHC Pirh2 expression was noted in 58.3% of the cases, and significantly asM-positive EC are highly aggressive tumors with a shortened survival rate, dismal outcome, and high risk of relapse after the standard protocol of therapy.Migraine is a common disabling disease with a complex pathophysiology. Headache is a frequent side effect after intravenous adenosine administration, although adenosine receptor antagonist, caffeine, relieves migraine headache. These observations suggest a possible involvement of adenosine signaling in headache and migraine pathophysiology. In a randomized, double-blinded, placebo-controlled, crossover study, 18 participants diagnosed with migraine without aura received 120 µg/kg per minute adenosine or placebo over 20 minutes. Headache intensity, migraine-associated symptoms, vital signs, the diameter of the superficial temporal artery (STA), blood flow velocity in the middle cerebral artery (V MCA ), and facial skin blood flow were measured at baseline and every 10 minutes until 2 hours after infusion start. The primary end point was the difference in the incidence of migraine attacks after adenosine infusion compared with placebo. Eighteen participants completed the study. L-α-Phosphatidylcholine molecular weight We found no difference in the incidence of migraine after adenosine infusion (7 of 18, 39%) compared with placebo (3 of 18, 17%) ( P = 0.29). Fourteen participants reported headache after adenosine infusion (14 of 18, 78%) compared with placebo (6 of 18, 33%) ( P less then 0.01). Adenosine increased heart rate ( P less then 0.001), facial skin blood flow ( P less then 0.05), and STA diameter (AUC T0-20min , P = 0.01) and decreased V MCA (AUC T0-20min , P less then 0.001) compared with placebo. Adenosine induced headache accompanied by a short-lasting ( less then 30 minutes) dilation of intracerebral and extracerebral arteries. The nonsignificant migraine induction might be because of the presence of several adenosine receptors with counteracting signaling, highlighting the need of more selective modulators to dissect the implication of adenosine in migraine.

Post-operative healing after clitoral reconstruction (CR) for Female Genital Mutilation/Cutting (FGM/C) can be long and painful due to prolonged clitoral re-epithelialization time (3 months). Autologous Platelet-Rich Plasma (A-PRP) might reduce post operative clitoral epithelialization time and pain.

We assessed post-op clitoral re epithelialization time and pain after the use of intraoperative clitoral administration of A-PRP.

Five consecutive women underwent CR (Foldès technique) followed by the administration of A-PRP Regen Lab SA (Le Mont-sur-Lausanne, Switzerland) plasma and glue, respectively injected inside and applied above the re-exposed clitoris. We recorded surgical complications, post-operative clitoral pain (VAS), painkiller intake, time to complete re epithelialization and the experienced subjective changes in sexual response and perception of their own body image referred by women.

Sexual distress/dysfunction as well as the desire to be physically and symbolically "repaired" were the reasons behind women's requests for surgery. None of the women suffered from chronic vulvar or non-vulvar pain. All women achieved complete clitoral epithelialization by day 80. Three between day 54 and 70. Only one woman was still taking 1 g of Paracetamol twice a day at two-months post-op. She had stopped it before the three-month control. We did not have short nor long term complications. All women described easier access and stimulation of their clitoris, improved sexual arousal, lubrication, and pleasure, and said to be satisfied of their restored body image.

A-PRP could expedite post-op clitoral epithelialization and reduce post op pain after CR after FGM/C.

A-PRP could expedite post-op clitoral epithelialization and reduce post op pain after CR after FGM/C.Referred sensations (RS) are a common clinical phenomenon in patients with musculoskeletal pain; however, the underlying mechanisms of RS and implications for diagnosis and management are poorly understood. The location of referral seems to have a preferred site, but studies have suggested it can be redirected to a site of previous injury and pain. However, it is not known if the same phenomenon can occur for a much shorter-lasting painful stimulus in the trigeminal system. The aim of this study was to assess if RS location elicited with standardized palpation of the masseter muscle could be altered following a 10-minute painful infusion of hypertonic saline into the retromolar region. A total of 56 healthy participants participated in this cross-over study performed in 2 sessions separated by 1 hour. At each session, baseline and postinfusion assessments of masseter muscle mechanical sensitivity were performed using 2 different forces (0.5 kg and 2 kg). Between assessments, hypertonic saline (5%) or isotonic saline (control) were continuously infused into the retromolar region. Participants were asked to rate their mechanical sensitivity and any RS they experienced as well as to draw the location of the RS. No difference in mechanical sensitivity or RS frequency was seen after either infusion when compared with before infusion. However, the RS location was displaced on average 1.2 cm between the baseline and postinfusion assessments for the hypertonic saline infusion, which was significantly increased when compared with the isotonic saline infusion which was on average 0.4 cm. These novel findings indicate the potential to modify the location of RS in the trigeminal system following a relatively brief noxious input. Clinicians need to be aware of the possible rerouting of RS in patients with complex orofacial pain.This article describes the development of an advanced practice RN (APRN) council in a large hospital network. Despite obstacles, the council was able to demonstrate positive outcomes, which include standardization of the credentialing and onboarding process, productive networking, and an APRN-oriented education fair. The council has been able to guide workplace culture, establish and support vertical and horizontal interprofessional relationships, provide recommendations to relevant leadership boards, and develop standardized procedures.
