    The selective 5-HT(2A) receptor antagonist sarpogrelate has been clinically used for treatment in atherosclerotic diseases. However, it remains unknown whether administration of sarpogrelate inhibits intimal hyperplasia seen in autologous vein grafts. Therefore, we sought to clarify this question using an experimental rabbit vein graft model. Male rabbits were divided into two groups: a control group and a sarpogrelate-treated group. The jugular vein was interposed in the carotid artery in reversed fashion for 4 weeks and intimal hyperplasia of the grafted vein was measured (n = 8, in each group). Acetylcholine (ACh)-induced endothelium-dependent relaxation was tested by precontraction with prostaglandin F(2alpha) (PGF(2alpha), 5 muM) (n = 5, in each). endothelial nitric oxide synthase (eNOS) protein expression and superoxide production of these veins were also assessed. The suppression of intimal hyperplasia was significantly greater in the sarpogrelate-treated group than in the control group. ACh induced an endothelium-dependent relaxation in the sarpogrelate-treated group (but not in the control group). In endothelium-intact strips from the sarpogrelate-treated group, the nitric oxide (NO) synthase inhibitor nitroarginine enhanced the PGF(2alpha)-induced contraction and blocked the ACh-induced relaxation. Immunoreactive eNOS protein expression was similar between the two groups but superoxide production (estimated from ethidium fluorescence) in endothelial cells was significantly smaller in the sarpogrelate-treated group. The present results indicate that in vivo blockade of 5-HT(2A) receptors leads to an inhibition of intimal hyperplasia in rabbit vein graft. It is suggested that an increased function of endothelium-derived NO through a reduction in endothelial superoxide production may be a possible underlying mechanism for this. These novel findings support the clinical usefulness of sarpogrelate for preventing intimal hyperplasia in vein graft after bypass

    Full Text Available Abstract Background Despite a prodigious investment of funds, we cannot treat or prevent arteriosclerosis and restenosis, particularly its major pathology, arterial intimal hyperplasia. A cornerstone question lies behind all approaches to the disease: what causes the pathology? Hypothesis I argue that the question itself is misplaced because it implies that intimal hyperplasia is a novel pathological phenomenon caused by new mechanisms. A simple inquiry into arterial morphology shows the opposite is true. The normal multi-layer cellular organization of the tunica intima is identical to that of diseased hyperplasia; it is the standard arterial system design in all placentals at least as large as rabbits, including humans. Formed initially as one-layer endothelium lining, this phenotype can either be maintained or differentiate into a normal multi-layer cellular lining, so striking in its resemblance to diseased hyperplasia that we have to name it "benign intimal hyperplasia". However, normal or "benign" intimal hyperplasia, although microscopically identical to pathology, is a controllable phenotype that rarely compromises blood supply. It is remarkable that each human heart has coronary arteries in which a single-layer endothelium differentiates early in life to form a multi-layer intimal hyperplasia and then continues to self-renew in a controlled manner throughout life, relatively rarely compromising the blood supply to the heart, causing complications requiring intervention only in a small fraction of the population, while all humans are carriers of benign hyperplasia. Unfortunately, this fundamental fact has not been widely appreciated in arteriosclerosis research and medical education, which continue to operate on the assumption that the normal arterial intima is always an "ideal" single-layer endothelium. As a result, the disease is perceived and studied as a new pathological event caused by new mechanisms. The discovery that normal

    Full Text Available Genetic P300/CBP-associated factor (PCAF variation affects restenosis-risk in patients. PCAF has lysine acetyltransferase activity and promotes nuclear factor kappa-beta (NFκB-mediated inflammation, which drives post-interventional intimal hyperplasia development. We studied the contributing role of PCAF in post-interventional intimal hyperplasia.PCAF contribution to inflammation and intimal hyperplasia was assessed in leukocytes, macrophages and vascular smooth muscle cells (vSMCs in vitro and in a mouse model for intimal hyperplasia, in which a cuff is placed around the femoral artery. PCAF deficiency downregulate CCL2, IL-6 and TNF-alpha expression, as demonstrated on cultured vSMCs, leukocytes and macrophages. PCAF KO mice showed a 71.8% reduction of vSMC-rich intimal hyperplasia, a 73.4% reduction of intima/media ratio and a 63.7% reduction of luminal stenosis after femoral artery cuff placement compared to wild type (WT mice. The association of PCAF and vascular inflammation was further investigated using the potent natural PCAF inhibitor garcinol. Garcinol treatment reduced CCL2 and TNF-alpha expression, as demonstrated on cultured vSMCs and leukocytes. To assess the effect of garcinol treatment on vascular inflammation we used hypercholesterolemic ApoE*3-Leiden mice. After cuff placement, garcinol treatment resulted in reduced arterial leukocyte and macrophage adherence and infiltration after three days compared to untreated animals.These results identify a vital role for the lysine acetyltransferase PCAF in the regulation of local inflammation after arterial injury and likely the subsequent vSMC proliferation, responsible for intimal hyperplasia.

    Intimal hyperplasia of autologous vein grafts is a critical problem affecting the long-term patency of many types of vascular reconstruction. Within intimal hyperplasia lesions, smooth muscle cells are a major component, playing an essential role in the pathological process. Given that bone marrow-derived cells may differentiate into smooth muscle cells in the neointima of injured arteries, we hypothesized that the bone marrow may serve as a source for some of the smooth muscle cells within intimal hyperplasia lesions of vein grafts. To test this hypothesis, we used an established mouse model for intimal hyperplasia in wild-type mice that had been transplanted with bone marrow from a green fluorescent protein (GFP+/+) transgenic mouse. High-resolution confocal microscopy analysis performed 2 and 8 weeks after grafting demonstrated expression of GFP in 5.4 +/- 0.8% and 11.9 +/- 2.3%, respectively, of smooth muscle cells within intimal hyperplasia lesions. By 16 weeks, GFP expression in smooth muscle cells was not detected by immunohistochemistry; however, real-time PCR revealed that 20.2 +/- 1.7% of the smooth muscle cells captured from the neointima lesion by laser capture microdissection at 16 weeks contained GFP DNA. Our results suggest that bone marrow-derived cells differentiated into smooth muscle cells within the intimal lesion and may provide a novel clinical approach for decreasing intimal hyperplasia in vein grafts.

    Arteriovenous fistula (AVF) is the preferred hemodialysis access type because it has better patency rates and fewer complications than other access types. However, primary failure remains a common problem impeding AVF maturation and adding to patients’ morbidity and mortality. Juxta-anastomotic (or inflow) stenosis is the most common reason leading to primary failure, and percutaneous transluminal angioplasty (PTA) continues to be the gold standard treatment with excellent success rates. Intimal hyperplasia (IH) has been traditionally blamed as the main pathophysiologic culprit, but new evidence raises doubts regarding the contribution of IH alone to primary failure. We report a 64-year-old man with a two-stage brachio-basilic AVF that was complicated by failure four months after creation. Angiogram showed multiple juxta-anastomotic and mid-fistula stenotic lesions. PTA was successful in assisting maturation and subsequently cannulating AVF for hemodialysis treatment. We failed to identify the underlying cause of stenosis as biopsy specimens from fistula tissue obtained at the time of transposition revealed no occlusive IH. This case emphasizes the need for additional research on factors contributing to AVF failure besides IH, and highlights the need for more therapeutic options to reduce AVF failure rate.

    Intimal hyperplasia has been historically associated with improper venous remodeling and stenosis after creation of an arteriovenous fistula. Recently, however, we showed that intimal hyperplasia by itself does not explain the failure of maturation of 2-stage arteriovenous fistulas. We seek to evaluate whether intimal hyperplasia plays a role in the development of focal stenosis of an arteriovenous fistula. This study compares intimal hyperplasia lesions in stenotic and nearby nonstenotic segments collected from the same arteriovenous fistula. Focal areas of stenosis were detected in the operating room in patients (n= 14) undergoing the second-stage vein transposition procedure. The entire vein was inspected, and areas of stenosis were visually located with the aid of manual palpation and hemodynamic changes in the vein peripheral and central to the narrowing. Stenotic and nonstenotic segments were documented by photography before tissue collection (14 tissue pairs). Intimal area and thickness, intima-media thickness, and intima to media area ratio were measured in hematoxylin and eosin stained cross-sections followed by pairwise statistical comparisons. The intimal area in stenotic and nonstenotic segments ranged from 1.25 to 11.61 mm 2 and 1.29 to 5.81 mm 2 , respectively. There was no significant difference between these 2 groups (P=.26). Maximal intimal thickness (P=.22), maximal intima-media thickness (P=.13), and intima to media area ratio (P=.73) were also similar between both types of segments. This preliminary study indicates that postoperative intimal hyperplasia by itself is not associated with the development of focal venous stenosis in 2-stage fistulas. Copyright © 2017 Elsevier Inc.

    . However, the role of SHP-1 in intimal hyperplasia and restenosis has not been clarified in insulin resistance and diabetes. METHODS: We used a femoral artery wire injury mouse model, rodent models with insulin resistance and diabetes, and patients with type 2 diabetes. Further, we modulated SHP-1...... expression using a transgenic mouse that overexpresses SHP-1 in VSMCs (Shp-1-Tg). SHP-1 agonists were also employed to study the molecular mechanisms underlying the regulation of SHP-1 by oxidised lipids. RESULTS: Mice fed a high-fat diet (HFD) exhibited increased femoral artery intimal hyperplasia...... and decreased arterial SHP-1 expression compared with mice fed a regular diet. Arterial SHP-1 expression was also decreased in Zucker fatty rats, Zucker diabetic fatty rats and in patients with type 2 diabetes. In primary cultured VSMCs, oxidised LDL suppressed SHP-1 expression by activating Mek-1 (also known...

    The observation of intimal hyperplasia at bypass graft anastomoses has suggested a potential interaction between local hemodynamics and vascular wall response. Wall shear has been particularly implicated because of its known effects upon the endothelium of normal vessels and, thus, was examined as to its possible role in the development of intimal hyperplasia in arterial bypass graft distal anastomoses. Tapered (4-7 mm I.D.) e-PTFE synthetic grafts 6 cm long were placed as bilateral carotid artery bypasses in six adult, mongrel dogs weighing between 25 and 30 kg with distal anastomotic graft-to-artery diameter ratios (DR) of either 1.0 or 1.5. Immediately following implantation, simultaneous axial velocity measurements were made in the toe and artery floor regions in the plane of the anastomosis at radial increments of 0.35 mm, 0.70 mm, and 1.05 mm using a specially designed 20 MHz triple crystal ultrasonic wall shear rate transducer Mean, peak, and pulse amplitude wall shear rates (WSRs), their absolute values, the spatial and temporal wall shear stress gradients (WSSG), and the oscillatory shear index (OSI) were computed from these velocity measurements. All grafts were harvested after 12 weeks implantation and measurements of the degree of intimal hyperplasia (IH) were made along the toe region and the artery floor of the host artery in 1 mm increments. While some IH occurred along the toe region (8.35+/-23.1 microm) and was significantly different between DR groups (p<0.003), the greatest amount occurred along the artery floor (81.6+/-106.5 microm, mean +/- S.D.) (p < 0.001) although no significant differences were found between DR groups. Linear regressions were performed on the paired IH and mean, peak, and pulse amplitude WSR data as well as the absolute mean, peak, and pulse amplitude WSR data from all grafts. The mean and absolute mean WSRs showed a modest correlation with IH (r = -0.406 and -0.370, respectively) with further improvements seen (r = -0

    Saphenous veins used as arterial grafts are exposed to arterial levels of oxygen partial pressure (pO2), which are much greater than what they experience in their native environment. The object of this study is to determine the impact of exposing human saphenous veins to arterial pO2. Saphenous veins and left internal mammary arteries from consenting patients undergoing coronary artery bypass grafting were cultured ex vivo for 2 weeks in the presence of arterial or venous pO2 using an established organ culture model. Saphenous veins cultured with arterial pO2 developed intimal hyperplasia as evidenced by 2.8-fold greater intimal area and 5.8-fold increase in cell proliferation compared to those freshly isolated. Saphenous veins cultured at venous pO2 or internal mammary arteries cultured at arterial pO2 did not develop intimal hyperplasia. Intimal hyperplasia was accompanied by two markers of elevated reactive oxygen species (ROS): increased dihydroethidium associated fluorescence (4-fold, ppO2 is suggested by the observation that chronic exposure to tiron, a ROS scavenger, during the two-week culture period, blocked intimal hyperplasia. Electron paramagnetic resonance based oximetry revealed that the pO2 in the wall of the vessel tracked that of the atmosphere with a ~30 mmHg offset, thus the cells in the vessel wall were directly exposed to variations in pO2. Monolayer cultures of smooth muscle cells isolated from saphenous veins exhibited increased proliferation when exposed to arterial pO2 relative to those cultured at venous pO2. This increased proliferation was blocked by tiron. Taken together, these data suggest that exposure of human SV to arterial pO2 stimulates IH via a ROS-dependent pathway. PMID:25799140

    Although the aortic interposition bypass model has been widely used to evaluate biomaterials for bypass grafting, there is no comprehensive description of the procedure or of the distribution of intimal hyperplasia that results. The objectives of this study were to (1) review and summarize approaches of aortic interposition grafting in animal models, (2) determine the pertinent anatomy for this procedure, (3) validate this model in the rat and guinea pig, and (4) compare the distribution of intimal hyperplasia that develops in each species. A literature search was performed in PubMed from 1980 to the present to analyze the use of anesthesia, anticoagulation, antiplatelet agents, graft material, suture, and anastomotic techniques. Using 10-week-old male Sprague-Dawley rats and Hartley guinea pigs, we established pertinent aortic anatomy, developed comparable models, and assessed complications for each model. At 30 days, the graft and associated aorta were explanted, intimal formation was assessed morphometrically, and cellularity was assessed via nuclear counting. We reviewed 30 articles and summarized the pertinent procedural findings. Upon establishing both animal models, key anatomic differences between the species that affect this model were noted. Guinea pigs have a much larger cecum, increased retroperitoneal fat, and lack the iliolumbar vessels compared with the rat. Surgical outcomes for the rat model included a 53% technical success rate and a 32% technical error rate. Surgical outcomes for the guinea pig model included a 69% technical success rate and a 31% technical error rate. These two species demonstrated unique distribution of intimal hyperplasia at 30 days. Intimal hyperplasia in the rat model was greatest at two areas, the proximal graft (5400 μm 2 ; P guinea pig model developed similar intimal hyperplasia throughout the graft (4500-5100 μm 2 ; P guinea pig, and describe a unique distribution of intimal formation that results in both species

    The contribution of intimal hyperplasia (IH) to arteriovenous fistula (AVF) failure is uncertain. This observational study assessed the relationship between pre-existing, postoperative, and change in IH over time and AVF outcomes. Prospective cohort study with longitudinal assessment of IH at the time of AVF creation (pre-existing) and transposition (postoperative). Patients were followed up for up to 3.3 years. 96 patients from a single center who underwent AVF surgery initially planned as a 2-stage procedure. Veins and AVF samples were collected from 66 and 86 patients, respectively. Matched-pair tissues were available from 56 of these patients. Pre-existing, postoperative, and change in IH over time. Anatomic maturation failure was defined as an AVF that never reached a diameter > 6mm. Primary unassisted patency was defined as the time elapsed from the second-stage surgery to the first intervention. Maximal intimal thickness in veins and AVFs and change in intimal thickness over time. Pre-existing IH (>0.05mm) was present in 98% of patients. In this group, the median intimal thickness increased 4.40-fold (IQR, 2.17- to 4.94-fold) between AVF creation and transposition. However, this change was not associated with pre-existing thickness (r(2)=0.002; P=0.7). Ten of 96 (10%) AVFs never achieved maturation, whereas 70% of vascular accesses remained patent at the end of the observational period. Postoperative IH was not associated with anatomic maturation failure using univariate logistic regression. Pre-existing, postoperative, and change in IH over time had no effects on primary unassisted patency. The small number of patients from whom longitudinal tissue samples were available and low incidence of anatomic maturation failure, which decreased the statistical power to find associations between end points and IH. Pre-existing, postoperative, and change in IH over time were not associated with 2-stage AVF outcomes. Copyright © 2016 National Kidney Foundation, Inc

  15. A Computational Framework to Optimize Subject-Specific Hemodialysis Blood Flow Rate to Prevent Intimal Hyperplasia

    Development of excessive intimal hyperplasia (IH) in the cephalic vein of renal failure patients who receive chronic hemodialysis treatment results in vascular access failure and multiple treatment complications. Specifically, cephalic arch stenosis (CAS) is known to exacerbate hypertensive blood pressure, thrombosis, and subsequent cardiovascular incidents that would necessitate costly interventional procedures with low success rates. It has been hypothesized that excessive blood flow rate post access maturation which strongly violates the venous homeostasis is the main hemodynamic factor that orchestrates the onset and development of CAS. In this article, a computational framework based on a strong coupling of computational fluid dynamics (CFD) and shape optimization is proposed that aims to identify the effective blood flow rate on a patient-specific basis that avoids the onset of CAS while providing the adequate blood flow rate required to facilitate hemodialysis. This effective flow rate can be achieved through implementation of Miller's surgical banding method after the maturation of the arteriovenous fistula and is rooted in the relaxation of wall stresses back to a homeostatic target value. The results are indicative that this optimized hemodialysis blood flow rate is, in fact, a subject-specific value that can be assessed post vascular access maturation and prior to the initiation of chronic hemodialysis treatment as a mitigative action against CAS-related access failure. This computational technology can be employed for individualized dialysis treatment.

    Intimal hyperplasia (IH) is most commonly the cause of graft occlusion in infrainguinal bypass grafting for arterial occlusive disease. We investigated the influence of nitric oxide on the IH of the arterial vessel wall at the region of prosthetic bypass anastomoses. Experiments were performed in 10 Foxhound dogs. We used a technique of inducible nitric oxide synthase (iNOS) overexpression by a non-virus-mediated, liposome-based iNOS gene transfer. The plasmid pSCMV-iNOS, which drives the expression of iNOS under control of the cytomegalovirus promoter, was complexed with cationic liposomes (lipoplexes). Segments of both carotid arteries were pretreated by intramural injection of a lipoplex solution by using an infiltrator balloon catheter (Infiltrator Drug Delivery Balloon System). In each dog, iNOS was administered at one side, and a control vector (pSCMV2) was administered at the contralateral side. Carotid arteries were ligated, and bypass grafts (expanded polytetrafluoroethylene, 6-mm, ring enforced) were implanted on both sides. The proximal and distal anastomoses (end-to-side fashion; running nonabsorbable sutures) were placed in the pretreated regions. After 6 months, the prostheses were excised, and the intimal thicknesses of 50 cross sections (orcein staining) of each anastomosis were measured planimetrically. The average reduction of the neointima thickness of the iNOS side in proximal anastomoses at the prosthetic wall, suture region, and arterial wall was 43%, 52%, and 81%, respectively. In distal anastomoses, the average reduction was 40%, 47%, and 52%, respectively. All differences of neointima thickness between the iNOS and control sides were statistically significant (Wilcoxon test; P < or = .05). Inducible NOS expression is an efficient approach for inhibition of IH. In contrast to earlier studies, which investigated the efficacy of gene therapeutic NOS expression at 3 to 4 weeks after intervention, the novelty of our findings is that a single

    Leptomeningeal artery abnormalities in Cerebral Autosomal-Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) have not been extensively characterized. We quantified substructure and diameter of leptomeningeal arteries in CADASIL compared with age-matched controls and the very old; in addition, we characterized intimal thickening in CADASIL using immunohistochemistry. Frontal and temporal cortex of 6 genetically proven CADASIL brains (average age, 66 years), 6 controls without symptoms of cerebrovascular disease, and 6 very old brains (average age, 89 years) were examined for leptomeningeal artery intimal, medial, and adventitial thickness; inner diameter; and sclerotic index and for smooth muscle markers. The intima of CADASIL arteries was thickened 5-fold compared with controls and the very aged (PMedial thickness was lower in CADASIL compared with controls and the very old (PArterial diameters were not smaller in CADASIL compared with controls. Sclerotic index was significantly increased in CADASIL compared with other groups (Parteries in CADASIL include intimal thickening and medial thinning, but not luminal narrowing. Smooth muscle-like cells participate in neointimal thickening of CADASIL arteries.

    Full Text Available Background/Aims: Neointimal formation following vascular injury remains a major mechanism of restenosis, whereas the precise sources of neointimal cells are still uncertain. We tested the hypothesis that both injured arterial cells and non-arterial cells contribute to intimal hyperplasia. Methods: Following allograft transplantation of the balloon-injured carotid common artery (n = 3-6, the cellular composition of the transplant grafts and the origins of neointimal cells were measured by immunohistochemistry and immunofluorescence staining. Results: Smooth muscle actin (SMA-positive and CD68-positive cells were clearly observed 14 days later in the neointima after allograft transplantation of the balloon-injured carotid common artery, where re-endothelialization was not yet complete. Green fluorescent protein (GFP and wild-type (WT allograft transplantation revealed that the majority of the neointima cells were apparently from the recipient (≈85% versus the donor (≈15%. Both monocyte chemotactic protein-1 (MCP-1/CCR2 and stromal cell-derived factor-1 (SDF-1/CXCR4 signaling were involved in intimal hyperplasia, with bone marrow-derived cells also playing a role. Conclusion: These data support the hypothesis that intimal hyperplasia could develop in our novel rat allograft transplantation model of arterial injury, where neointima is attributable not only to local arterial cells but also non-arterial cells including the bone marrow.

    The aim of this study was to compare the performance of polytetrafluoroethylene (PTFE) grafts with luminal coating of immobilized heparin to that of standard PTFE grafts at six months. Twenty-eight common carotid arteries in fourteen sheep were bypassed with heparin-coated PTFE grafts (6 mm diameter, 6 cm length) on one side and standard PTFE grafts on the other. The grafts were explanted after six months. The thickness of intimal hyperplasia (IH) in open grafts was measured with histomorphometrical methods. Two of 14 heparinized PTFE grafts and nine of 14 grafts in the control PTFE-group were occluded at explantation (P=0.006). Six-month patency rates for heparinized PTFE grafts and for standard PTFE grafts were 86% and 36%, respectively. Mean graft anastomotic IH thickness in open grafts were 0.074 mm for heparinized PTFE grafts and 0.259 mm for PTFE-grafts (P=0.006). PTFE grafts with luminal coating containing immobilized heparin had significantly better patency and recruited less intimal hyperplasia than standard PTFE grafts at six months.

    Bypass graft thrombosis remains a significant mode of failure in prosthetic graft revascularization. The purpose of this investigation was to evaluate the long-term thromboresistant effect of heparin-bonded expanded polytetrafluoroethylene (ePTFE) graft using Carmeda BioActive Surface technology in a canine model. Bilateral femorofemoral artery bypass grafts with ePTFE grafts were performed in 25 adult grayhound dogs. In each animal, a heparin-bonded ePTFE graft (Propaten, WL Gore) was placed on one side, whereas a control nonheparin graft was placed on the contralateral side. The graft patency was assessed at 1, 6, 12, 18, and 24 months (n = 5 per group) following the bypass. Heparin bioactivity of the graft material was analyzed. The effect of intimal hyperplasia was also assessed. All bypass grafts were patent at 1 month. Significantly greater patency rates were noted in the Propaten group compared to the control group at 12, 18, and 24 months, which were 84%, 80%, and 80% vs. 55%, 35%, and 20%, respectively (P  0.05). Heparin-bonded ePTFE graft provides a thromboresistant surface and reduced anastomotic intimal hyperplasia at 2 years. The stable heparin bioactivity of the Propaten graft confers an advantage in long-term graft patency. Copyright © 2017 The Author(s). Published by Elsevier Inc. All rights reserved.

    The role of the Mas receptor in the activity of valsartan against intimal hyperplasia is unclear. Herein, we investigated the role of the angiotensin-converting enzyme 2 (ACE2)-angiotensin-(1-7)-Mas receptor axis on the activity of valsartan against intimal hyperplasiain balloon-injured rat aortic arteries. Wistar rats were randomized equally into the sham control group, injured group, and injured plus valsartan (20 mg/kg/d)-treated group. Valsartan significantly attenuated the vascular smooth muscle cell proliferation and intimal and medial thickening on days 14 and 28 after injury. The angiotensin-(1-7) levels as well as ACE2 and Mas receptor mRNA/protein expression were significantly decreased in the injured rats, compared to the uninjured rats; meanwhile, the angiotensin II level as well as the ACE and AT1 receptor mRNA/protein expression were increased (all P valsartan significantly increased the angiotensin-(1-7) levels as well as ACE2 and Mas receptor mRNA/protein expression but decreased the angiotensin II level, ACE and AT1 receptor mRNA/protein expression, as well as the p-ERK protein expression, compared to the injured group (all P valsartan attenuates neointimal hyperplasiain balloon-injured rat aortic arteries through activation of the ACE2-angiotensin-(1-7)-Mas axis as well as inhibition of the ACE-angiotensin II-AT1 and p-ERK pathways.

    OBJECTIVE: To evaluate the effects of the everolimus-eluting Xience™/Promus™ stent (EES) and the sirolimus-eluting Cypher™ stent (SES) on intimal hyperplasia (IH) in diabetic patients. BACKGROUND: Patients with diabetes mellitus have increased risk of in-stent restenosis after coronary stent...... implantation due to intimal hyperplasia (IH). METHODS: In a sub study of the Randomized Comparison of Everolimus-Eluting and Sirolimus-Eluting Stents in Patients Treated with Percutaneous Coronary Intervention (SORT OUT IV trial), serial intravascular ultrasound (IVUS) 10-month follow-up data were available...... in 88 patients, including 48 EES and 40 SES treated patients. IVUS endpoints included IH volume, in-stent % volume obstruction and changes in external elastic membrane (EEM) volume. RESULTS: Compared with the SES group, IH volume was increased in the EES group [median (interquartile range): 2.8 mm(3) (0...

    Coronary angioplasty (PTCA) is performed in about two million surgical procedures every year in the world, and coronary restenosis (CR) continues to be it's weakest point. There are four mechanisms involved in CR 1. Thrombosis, 2.elastic recoil, 3. Constrictive arterial remodeling; and 4. Intimal hyperplasia. The first three are managed with Stents, inhibitors of GP lib//iiia, antiagregants and anticoagulants. The fourth is believed to be the only responsible of post Stent CR. endothelin 1(ET1) produces cellular proliferation. Impact of the anti ET1 anti bodies by intra coronary injection, or generated by immune response at the subcutaneous (SC) application of ET1, on the NI growth in porcines, who have undergone barotrauma with Stent, is expected to be demonstrated. PTCA was performed in 12 pigs (36 arterial specimens). They were sacrificed after four weeks of follow up. Specimens were divided in three groups, previously randomized, resulting in 12 specimens a group. The placebo group received intracoronary infusion of saline solution immediately after the barotraumas. The second group received intracoronary infusion of AET1 antibodies and the third group received SC injection of ET1 fourteen days before the trauma. Segments were studied with IVUS and hystomotphometric analysis. Statistical analysis: it was performed by the student t in order to compare independent measures. Because of the small size of the groups, the Mann Whitney test was applied. A double tale analysis was performed in both cases. A significant reduction of the NI area was obtained both with the injection of AET1 Abs and ET1 SC (p 0.001) in the IVUS and the hystomotphometric analyses. AET1 antibodies seem to prevent the post Stent NI growth. There is no significant advantage between both forms of injection

    Purpose: Endovascular brachytherapy for the prevention of intimal hyperplasia (IH) and restenosis after balloon/stent angioplasty has proven effective both in animal preparations and clinical trials. A variety of β-emitting isotopes and catheter-based devices have been developed for the delivery of low-dose radiation in clinical coronary and peripheral trials. No platform, however, has yet been developed for brachytherapy in concert with vascular surgical operations. The purpose of this study was to evaluate the vascular histopathologic response following balloon injury to rabbit carotid arteries with and without topically applied low-dose β-radiation. Methods: The β-emitting isotope strontium-90 (Sr-90) was conjugated onto the matrix of polypropylene (PLYP) mesh. Rabbit carotid arteries were balloon-injured with a no. 2 embolectomy catheter. Six carotid arteries were wrapped with nonradioactive PLYP mesh (controls) and Sr-90 (∼90 μCi) PLYP mesh in order to deliver low-dose radiation to the vessel wall from the external (adventitial) surface. Tissue was harvested at 6 weeks and processed for histologic examination. Results: There was consistent blockade of fibrocellular neointima formation with virtually no neointima present in all treated segments, compared to moderate neointima formation in controls. Medial thinning and smooth muscle cell (SMC) necrosis were also associated with topical brachytherapy. Conclusion: β-Radiation applied by an externally wrapped PLYP mesh labeled with Sr-90 markedly suppressed neointima formation in an animal vascular surgical injury model. Further studies, however, are necessary to determine a suitable isotope and dosage for clinical application

    Hydrocephalus is a common neurological disorder in children and the result of a variety of causes. However, with the advancement of imaging modalities, particularly MRI, previously reported rarer causes of hydrocephalus in children are now being more readily appreciated. We report an 11-year-old boy with diffuse villous hyperplasia of the choroid plexus. He had a ventriculo-peritoneal (VP) shunt in-situ and a prior diagnosis from infancy of congenital aqueduct stenosis as the cause of his hydrocephalus. His current presentation was with further shunt dysfunction. CT and MRI demonstrated enlarged choroid plexuses but did not confirm aqueduct stenosis. CSF overproduction was demonstrated from the externalized ventricular drain. The enlarged choroid plexuses were surgically resected and histology confirmed choroid plexus hyperplasia. Identification of choroid plexus hyperplasia is important since the neurosurgical management of hydrocephalus is not VP shunt insertion, but resection of the hyperplastic choroid plexus. (orig.)

    Intimate partner violence (IPV) and child abuse (CA) are two forms of family violence with shared qualities and risk factors, and are forms of violence that tend to overlap. Acceptability of violence in partner relationships is a known risk factor in IPV just as acceptability of parent-child aggression is a risk factor in CA. We hypothesized that these acceptability attitudes may be linked and represent the expression of a general, underlying nonspecific acceptance of violence in close family relationships. The sample involved 164 male IPV offenders participating in a batterer intervention program. Implicit measures, which assess constructs covertly to minimize response distortions, were administered to assess acceptability of partner violence against women and acceptability of parent-child aggression. To determine whether acceptability attitudes regarding both forms of violence were related to a higher order construct tapping general acceptance of family violence, Bayesian confirmatory factor analyses were conducted. Findings supported a hierarchical (bifactor) model with a general factor expressing a nonspecific acceptance of family violence, and two specific factors reflecting acceptability of violence in intimate partner and parent-child relationships, respectively. This hierarchical model supporting a general acceptance of violence in close family relationships can inform future research aiming to better understand the connections between IPV and CA.

    To assess the impact of urinary symptoms associated with benign prostatic hyperplasia and its treatment with silodosin, on quality of life (QoL) and sexual function, depending on age, severity of symptoms, time on treatment and prostate size. A cross-sectional, observational study was conducted in 305 urology practices all around Spain. Socio-demographic and clinical data were collected and patients filled the following questionnaires: EQ-5D, Sexual Function Index (SFI) and International Prostate Symptom Score (IPSS). Multiple regression models were used to determine factors independently associated with patients' QoL. A total of 1,019 patients were enrolled, mean (SD) for: age 62.7 (5.7), EQ-5D 89.9 (13.9), sexual drive-SFI 3.71 (1.67), erection-SFI 6.11 (3.08), ejaculation-SFI 4.50 (2.06) problems-SFI 6.85 (3.37) and overall satisfaction-SFI 2.00 (0.99). The EQ-5D and SFI score were statistically lower with: older age, severe LUTS and greater prostate size (P<.01), but no differences were found related to time on treatment with silodosin. The EQ-5D score was positively associated with sexual satisfaction and desire size of SFI and the EQ-5D VAS score, and negatively with disability, semi-urban residence and comorbidities in the multiple regression analyses. Severe LUTS and older age are associated to a greater deterioration in sexual function and quality of life. However time on treatment with silodosin does not produce deterioration in the quality of life. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

    Our aim was to determine the pathway underlying the effects of continuous positive airway pressure (CPAP) adherence on intimate relationship with bed partner in men with obstructive sleep apnea (OSA). We hypothesized that CPAP with good adherence affected the intimate relationship with bed partner directly and indirectly, and it was mediated through daytime sleepiness and activity level in men with OSA. Data were obtained from an education program for enhancing CPAP adherence. Men who were newly diagnosed of OSA and CPAP therapy naïve were recruited in a tertiary teaching hospital. Self-reported quality of life [Functional Outcomes of Sleep Questionnaire], daytime sleepiness [Epworth Sleepiness Scale (ESS)], and negative emotion symptoms [depression, anxiety, stress scale] were assessed before and after CPAP treatment at 1-year assessment. Seventy-three men were included in the data analysis, with a mean ± SD age of 52 ± 10 years, body mass index of 29.0 ± 5.2 kg/m(2), ESS of 9.5 ± 5.6, and median [interquartile range(IR)] apnea and hypopnea index of 31 (21, 56) events/h. The median (IR) CPAP daily usage was 4.3(0, 6.1) h/day. From the path analysis, CPAP therapy was shown to improve intimate relationship directly (ß = 0.185) and indirectly (ß = 0.050) by reducing daytime sleepiness and increasing activity level. However, negative emotion symptoms were not the mediators between CPAP adherence and the intimate relationship. CPAP therapy with good adherence is related directly and indirectly to a better intimate relationship with bed partner in men with OSA. It was possibly attributed to reduced daytime sleepiness and increased activity level.

    Human aortocoronary vein grafts fail due to accelerated occlusive disease. The possibility that this is related to cellular hyperplasia was investigated in a rabbit model where kinetics of vein graft thickening, endothelial (EC) repair, and smooth muscle cell (SMC) proliferation were measured from 2 days to 24 weeks after implanting jugular vein segments in the carotid artery. Immediately after graft placement focal EC denudation was observed. These defects were repaired within 1 week and did not recur. By 4 weeks intimal area had increased 30 fold from 0.028 +/- 0.004 to 0.705 +/- 0.021 mm 2 , and a 24 weeks was 0.93 +/- 0.21 mm 2 . This response did not produce a reduction in graft lumen area. EC and SMC thymidine-labeling index were measured by en face and cross-section autoradiography after injection of 3 H-thymidine and perfusion fixation. Despite rapid EC surface repair EC labeling index remained elevated and only returned to normal levels at 12 weeks; SMC labeling was 10 fold greater than baseline even at 24 weeks (0.22% vs 0.02%). SMC mass demonstrated morphometrically increased between 2 and 12 weeks. Intimal thickening in vein grafts is due to SMC proliferation and develops after the EC layer has been restored. In contrast, intimal SMC proliferate in damaged arteries when the EC layer is absent and cease when the EC layer is regenerated

    We present a case of unilateral adrenal medullary hyperplasia in a 63-year-old woman with clinical signs and symptoms of pheochromocytoma unassociated with multiple endocrine neoplasia. The surgically removed adrenal gland revealed diffuse medullary hyperplasia with multiple micronodules measuring up to 2 mm. The micronodules were composed of enlarged chromaffin cells with atypia, histologically similar to those of pheochromocytoma, forming small solid alveolar patterns separated by a fibrovascular stroma. Removal of the hyperplastic adrenal gland resulted in disappearance of paroxysmal nocturnal hypertension and palpitation. These results suggest that diffuse and nodular medullary hyperplasia is the precursor of pheochromocytoma.

    There exist limited data on the relative degree of acute injury and late healing of the radial artery after transradial artery (TRA) percutaneous coronary intervention (PCI) with a 7F sheathless guide catheter compared with a 6F sheath/guide combination. We used ultrahigh-resolution (55 MHz) vascular ultrasound to compare intimal-medial thickening (IMT) and early and late radial artery (RA) injury resulting from a sheathless 7F guide catheter versus a 6F sheath/guide combination for TRA-PCI. Forty-one consecutive consenting patients undergoing elective nonemergent TRA-PCI at a single institution from June 2016 to December 2016 were included. Patients were randomized (stratified by sex) to undergo TRA-PCI using a 7F sheathless guide catheter versus a 6F sheath/6F guide combination. Ultrahigh-resolution vascular ultrasound (55MHz) of the RA access site was performed at 24hours and 90days post-TRA-PCI. The primary outcome of the study was a noninferiority comparison of radial artery IMT thickness at 90days. PCI success rates, fluoroscopy times, number of guides used, and crossover rates to a femoral approach were also compared. Baseline characteristics were similar between groups. Radial arterial IMT (mm) was similar between the 7F sheathless and 6F sheath/guide groups at 24hours (0.27 vs 0.29, respectively; P=.43) and at 90days (0.35 vs 0.34, respectively; P=.96). The P value for the noninferiority testing of a 0.07-mm limit was .002. Limited access site intimal tears were relatively common in both groups at 24hours (4 vs 5, P=.53) but often healed by 90days. Radial artery occlusion was infrequent at 90days (2 vs 1, P=.10), and no frank dissections were noted. PCI success rates (100% vs 95%, P=.59), fluoroscopy times (16 vs 12minutes, P=.17), number of guides used (1.1 vs 1.2, P=.48), and femoral crossover rates (0% vs 0%) were similar between the 2 respective groups. A 7F sheathless approach to TRA-PCI results in no more IMT and early or late RA trauma than a

    Full Text Available Angiolymphoid hyperplasia with eosinophilia is a disease of the occident. It is mainly seen in middle aged women. It presents as multiple small pink or purple popular or nodular eruptions, in the head and neck area. Lesions of angiolymphoid hyperplasia with eosinophilia are often confused with lesions of Kimura’s disease, which is more common in young males. We report a case of angiolymphoid hyperplasia with eosinophilia in a 34 year old female. The patient is responding to monthly intralesional triamcinolone acetate along with cryotherapy with liquid nitrogen. This case is being reported due to its rarity in Indian patients.

    Subareolar sclerosing duct hyperplasia (SSDH) remains to be fully characterized nearly 20 years after initial description. Thirty-five SSDH cases diagnosed over a 16-year period (January 2000 to December 2015) were reviewed. All patients were female (mean age = 59 years, range = 18-80) who had presented with a unilateral solitary lesion (left 22, right 13) with a mean size of 1.3 cm (range = 0.4-3.0 cm), and showed florid and papillary epithelial hyperplasia with dense sclerosis without involvement of nipple or areolar epidermis. Significant lesions concurrent within SSDH included low-grade adenosquamous carcinoma (n = 1), ductal carcinoma in situ (DCIS; n = 1), lobular carcinoma in situ (LCIS; n = 1), and atypical ductal hyperplasia (ADH; n = 13). No case of SSDH recurred in a mean follow-up of 44 months (range = 6-189). Subsequent significant lesions occurred in 6 patients: DCIS (n = 3; ipsilateral 2, contralateral 1), ipsilateral ADH (n = 2), and ipsilateral atypical lobular hyperplasia (n = 1). Long-term follow-up for patients with SSDH is indicated as DCIS can occur subsequently in either breast.

    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and “on-time” puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

    Objective: The study was to evaluate the effect of beta irradiation on intimal proliferation response in vein grafts. Methods: An autogenous vein graft model was established in 40 rats by transplanting internal branch of jugular vein to carotid artery by end-to-end anastomosis. The vein was irradiated by 32 P before anastomosis. Four dose schedules were studied: (1) control graft (nonirradiated); (2) irradiated with 8 Gy; (3) 18 Gy; and (4) 36 Gy. The grafted veins were harvested at 2 weeks after the operation. IH (intimal hyperplasia) and SMC (smooth muscle cell) proliferation were histologically and immuno-histochemically observed and analyzed by a computer digitalising system. Results: In 18 Gy and 36 Gy-irradiated grafts compared with the control, there was a significant decrease in the average intimal thickness (P 0.05). Immunohistochemical analysis of PCNA indicated decrease of positive cells in both 18 Gy and 36 Gy groups compared with 8 Gy and the control group (P 0.05) groups, and there was also no significant difference between 8 Gy and the control group (P > 0.05). Conclusion: These preliminary results demonstrate that proper dose of beta irradiation in vein graft inhibits smooth muscle cells proliferation and neo-intimal hyperplasia in rat

    Purpose. To investigate the efficacy of oral administration of cilostazol to inhibit pseudointimal/intimal hyperplasia in swine TIPS models. Methods. Successful TIPS creation was carried out in 11 of 12 healthy young pigs (20-25 kg). In the treatment group (n = 6), both cilostazol and aspirin were administered daily, from the first day of TIPS creation. The control group (n = 5) was administered only aspirin. The animals were followed-up for 2 weeks and then killed. The specimen (including portal vein, hepatic parenchymal tract, hepatic vein, and inferior vena cava) and stents were carefully bisected in a longitudinal fashion. The control group was compared with the treatment group by means of a gross and histologic evaluation of the degree of pseudointimal/intimal hyperplasia in the shunt. Results. At the gross evaluation, the control group showed considerably more pseudointimal/intimal hyperplasia than the treatment group. Using microscopic evaluation, there was a statistically significant difference (p < 0.05) in the mean maximum pseudointimal/intimal hyperplasia thickness between the control group (2.97 ± 0.33 mm) and treatment group (0.73 ± 0.27 mm). Conclusion. Oral administration of cilostazol may have been effective in reducing pseudointimal/intimal hyperplasia in swine TIPS models

    Full Text Available A hiperplasia intimal ocorre em resposta à lesão vascular, pode complicar significantemente os procedimentos vasculares abertos e endovasculares, levando a diferentes graus de estenose do lume vascular e isquemia. De certo modo, a hiperplasia intimal está presente em todos os tipos de reconstruções vasculares, incluindo enxertos autólogos, homólogos e sintéticos, após angioplastias com ou sem colocação de stent e em órgãos transplantados. Um dos maiores desenvolvimentos experimentais nos últimos anos, para prevenção da hiperplasia intimal, é a utilização da radiação ionizante. A radiação ionizante inibe a proliferação de muitos tipos celulares, incluindo fibroblastos e células musculares lisas in vitro e a síntese de colágeno em culturas de fibroblastos. Modelos animais de experimentação têm sido utilizados para o desenvolvimento de novas estratégias de tratamento e entendimento dos mecanismos fisiopatológicos básicos da hiperplasia intimal. Assim, o objetivo desta revisão e atualização da literatura é o de expor os diferentes modelos de animais de experimentação para o desenvolvimento de hiperplasia intimal, o tipo de lesão empregada, as artérias mais utilizadas e os efeitos encontrados com o uso de diferentes tipos de fontes de radiação ionizante.Most complications that may occur in response to vascular injury of endovascular and open vascular procedures are due to intimal hyperplasia. To a certain extent, intimal hyperplasia is present in all types of vascular reconstruction, including autologous grafts, allografts, and prosthetic grafts found in solid organs transplanted, having a substantial role in chronic rejection and following angioplasty with or without stenting. One of the greatest developments in recent years towards prevention of intimal hyperplasia is the use of ionizing radiation. Ionizing radiation inhibits proliferation of many cell types including fibroblasts and smooth muscle cells

    Intimal hyperplasia is associated with graft failure and vascular sutures in the first year after surgery and in postangioplasty restenosis. Allium sativum (common garlic) lowers cholesterol and has antioxidant effects; it also has antiplatelet and antitumor properties and, therefore, has great potential to reduce or inhibit intimal hyperplasia of the arteries. Our objective is to determine if the garlic has an efficacy to inhibit myointimal hyperplasia compared to cilostazol. Female New Zealand rabbits were divided into the following groups (n=10 each) according to treatment: group A, garlic, 800 µg×kg-1×day-1, orally; group C, cilostazol, 50 mg.day-1, orally; group PS, 10 ml of 0.9% physiological saline solution, orally. Our primary is the difference of the mean of myointimal hyperplasia. Statistical analysis was performed by using ANOVA and Tukey tests, as well as the Chi-square test. We calculated the 95% confidence interval for each point estimate, and the P value was set as Allium sativum had the same efficacy in inhibiting myointimal hyperplasia when compared to the positive control, cilostazol.

    The effects of chronic local irritation have been seen commonly in the form of fibroma or mucocele in children. We report a ten year old girl with the chief complaint of swelling in the lower right region of labial mucosa which was diagnosed clinically as mucocele and histologically as fibro-epithelial hyperplasia. Surgical excision was done under local anesthesia with no post-operative complication.

Twenty-two cases in this study were...... with an ovarian tumor. PTH was found in 20 (91%) of the 22 cases in the Danish study. On the basis of this association of PTH with APSTs with implants and the close morphologic resemblance of PTH, not only to primary ovarian APSTs but also to noninvasive epithelial implants and endosalpingiosis, we speculate...... of ovarian and extraovarian low-grade serous proliferations (APST, noninvasive epithelial implants, and endosalpingiosis) that postulates that all of these lesions are derived from PTH, which appears to be induced by chronic inflammation. If this hypothesis is confirmed, it can be concluded that low...

    Papillary endothelial hyperplasia (Masson's tumour) is a reactive proliferation of endothelium producing papillary structures with fibrovascular cores. Dilatation, stasis and accompanying inflammation have been incriminated as the inciting events, evident by the presence of this lesion in haemorrhoids, urethral caruncles and laryngeal polyps. We present here a case of papillary endothelial hyperplasia in angiokeratoma hitherto undescribed despite sharing common etiopathogenetic features of dilatation and stasis with other aforementioned lesions.

    Intimate partner violence is a common source of physical, psychological, and emotional morbidity. In the United States, approximately 1.5 million women and 834,700 men annually are raped and/or physically assaulted by an intimate partner. Women are more likely than men to be injured, sexually assaulted, or murdered by an intimate partner. Studies suggest that one in four women is at lifetime risk. Physicians can use therapeutic relationships with patients to identify intimate partner violence, make brief office interventions, offer continuity of care, and refer them for subspecialty and community-based evaluation, treatment, and advocacy. Primary care physicians are ideally positioned to work from a preventive framework and address at-risk behaviors. Strategies for identifying intimate partner violence include asking relevant questions in patient histories, screening during periodic health examinations, and case finding in patients with suggestive signs or symptoms. Discussion needs to occur confidentially. Physicians should be aware of increased child abuse risk and negative effects on children's health observed in families with intimate partner violence. Physicians also should be familiar with local and national resources available to these patients.

    Endometrial hyperplasia is a precancerous lesion of the endometrium, commonly presenting with uterine bleeding. If managed expectantly, it frequently progresses to endometrial carcinoma, rates of which are increasing dramatically worldwide. However, the established treatment for endometrial hyperplasia (progestogens) involves multiple side effects and leaves the risk of recurrence. Metformin is the most commonly used oral hypoglycaemic agent in type 2 diabetes mellitus. It has also been linked to the reversal of endometrial hyperplasia and may therefore contribute to decreasing the prevalence of endometrial carcinoma without the fertility and side effect consequences of current therapies. However, the efficacy and safety of metformin being used for this therapeutic target is unclear and, therefore, this systematic review will aim to determine this. We will search the following trials and databases with no language restrictions: Cochrane Gynaecology and Fertility Specialised Register; Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; EBSCO Cumulative Index to Nursing and Allied Health Literature; PubMed; Google Scholar; ClinicalTrials.gov; the WHO International Trials Registry Platform portal; OpenGrey and the Latin American and Caribbean Health Sciences Literature (LILACS). We will include randomised controlled trials (RCTs) of use of metformin compared with a placebo or no treatment, conventional medical treatment (eg, progestogens) or any other active intervention. Two review authors will independently assess the trial eligibility, risk of bias and extract appropriate data points. Trial authors will be contacted for additional data. The primary review outcome is the regression of endometrial hyperplasia histology towards normal histology. Secondary outcomes include hysterectomy rate; abnormal uterine bleeding; quality of life scores and adverse reactions to treatments. Dissemination of the completed review will be through the Cochrane

    Three unusual cases of pseudocarcinomatous (pseudoepitheliomatous) hyperplasia (PH) affecting chronic osteomyelitic mandibular sequestra are reported to highlight the differences with the various squamous neoplasms which occur in that site. In two patients carrying a mandibular graft following the excision of an ameloblastoma, mucosal ulcers resulted in chronic osteomyelitis. In a third patient, an apical dental infection was associated with fistulated osteomyelitis. Histology of the three sequestra showed an intraosseous squamous proliferation. It was characterized by a peripheral involvement of medullary spaces, the more mature epithelial layer covering the bone trabeculae without intervening stroma, and the basal type epithelial layer surrounding a central fibrovascular core. There were no histological or cytological signs of malignancy. PH shows an inverted pattern when compared with the centro-medullary tumoural islands seen in the various oral or odontogenic squamous neoplasms which occur in the jaws. The lack of signs of malignancy distinguish PH from common squamous cell carcinomas. A short clinical course is an important feature in the distinction of PH from the well differentiated squamous cell carcinomas which may develop in fistulated chronic osteomyelitis.

    Congenital adrenal hyperplasia (CAH) describes a family of disorders that comes from enzymatic deficiencies in cortisol production, with 21-hydroxylase deficiency causing ∼90% of cases. Distinction is made between the severe classical form and milder nonclassical form of CAH. Molecular genetic analysis is used to confirm the hormonal diagnosis. A high rate of genotype-phenotype disconcordance has been found in 21-hydroxylase deficiency. The goal of treatment is to replace with synthetic glucocorticoids and mineralocorticoids and suppress adrenal androgen production. The treatment of patients affected with nonclassical CAH, particularly males, remains controversial. Variable synthetic glucocorticoids are used and new modes of glucocorticoid delivery are under investigation. To improve height, growth hormone and other adjuvant therapies are employed. Long-term outcomes of genital surgery using modern techniques in females affected with classical CAH continue to be investigated. Prenatal treatment with dexamethasone is available to avoid ambiguous genitalia in these females. Although studies have shown its safety to mother and fetus, prenatal treatment is still regarded as experimental. Currently, prenatal diagnosis of CAH can only be obtained through invasive methods. Recently, the detection of cell-free fetal DNA in maternal plasma has made it possible to make this diagnosis earlier and noninvasively. © 2016 S. Karger AG, Basel.

    Full Text Available Collateral intimate partner homicide (CIPH is an underinvestigated genre of intimate partner violence (IPV where an individual(s connected to the IPV victim is murdered. We conducted a content analysis of a statewide database of CIPH newspaper articles (1990-2007. Out of 111 collateral murder victims, there were 84 IPV female focal victims and 84 male perpetrators. The most frequently reported CIPH decedent was the focal victim’s new partner (30%; 45% of focal victims were themselves killed. News reports framed CIPH as the unexpected result of interpersonal conflict, despite evidence of a systematic pattern of coercion and violence that capitulated in murder.

    The role of inflammatory cells in thyroid epithelial cell (thyrocyte) hyperplasia is unknown. Here, we demonstrate that thyrocyte hyperplasia in IFN-gamma-/- NOD.H-2h4 mice has an autoimmune basis. After chronic exposure to increased dietary iodine, 60% of IFN-gamma-/- mice had severe thyrocyte hyperplasia with minimal or moderate lymphocyte infiltration, and thyroid dysfunction with reduced serum T4. All mice produced anti-thyroglobulin autoantibody. Some wild-type NOD.H-2h4 mice had isolated areas of thyrocyte hyperplasia with predominantly lymphocytic infiltration, whereas IL-4-/- and 50% of wild-type NOD.H-2h4 mice developed lymphocytic thyroiditis but no thyrocyte hyperplasia. Both thyroid infiltrating inflammatory cells and environmental factors (iodine) were required to induce thyrocyte hyperplasia. Splenocytes from IFN-gamma-/- mice with thyrocyte hyperplasia, but not splenocytes from naïve IFN-gamma-/- mice, induced hyperplasia in IFN-gamma-/- NOD.H-2h4.SCID mice. These results may provide clues for understanding the mechanisms underlying development of epithelial cell hyperplasia not only in thyroids but also in other tissues and organs.

Between November 2014 and April 2016, all patients satisfying the eligibility criteria underwent either bTURP or PVP under sedoanalgesia after randomisation. The groups were compared for functional outcomes, visual analogue scale (VAS) pain scores (range 0-10), perioperative variables and complications, with a follow-up of 3 months. In all, 42 and 36 patients underwent bTURP and PVP under sedoanalgesia, respectively. The mean VAS pain score was operating time [mean (SD) 55.64 (12.8) vs 61.79 (14.2) min, P  = 0.035], shorter duration of hospitalisation [mean (SD) 14.58 (2.81) vs 19.21 (2.82) h, P  post-void residual urine volume at 3 months were similar in both groups. None of our patients required re-admission or re-operation. Both PVP and bTURP can be carried out safely under sedoanalgesia with excellent treatment outcomes.

    Full Text Available Adenomatoid hyperplasia (AH is an uncommon, non-neoplastic swelling on the palate caused due to hyperplasia of the mucinous acini. The lesion clinically presents as a sessile tumor-like nodule resembling pleomorphic adenoma. Histopathologic findings include lobules of enlarged mucinous acini which are filled with secretory granules. The nuclei are squeezed to the basal portions, associated with focal inflammation and ductal dilatation, and a history of trauma is often elicited. Here, we report a rare case of AH of the lower lip in a 20-year-old male patient, which mimics a mucous retention cyst or mucocele.

    Hyperplasia of the PTG underlies the secondary hyperparathyroidism (SHPT) observed in CKD, but the mechanism underlying this hyperplasia is incompletely understood. Because aberrant cyclooxygenase 2 (COX2) expression promotes epithelial cell proliferation, we examined the effects of COX2 on the parathyroid gland in uremia. In patients with ESRD who underwent parathyroidectomy, clusters of cells within the parathyroid glands had increased COX2 expression. Some COX2-positive cells exhibited two nuclei, consistent with proliferation. Furthermore, nearly 78% of COX2-positive cells expressed proliferating cell nuclear antigen (PCNA). In the 5/6-nephrectomy rat model, rats fed a high-phosphate diet had significantly higher serum PTH levels and larger parathyroid glands than sham-operated rats. Compared with controls, the parathyroid glands of uremic rats exhibited more PCNA-positive cells and greater COX2 expression in the chief cells. Treatment with COX2 inhibitor celecoxib significantly reduced PCNA expression, attenuated serum PTH levels, and reduced the size of the glands. In conclusion, COX2 promotes the pathogenesis of hyperparathyroidism in ESRD, suggesting that inhibiting the COX2 pathway could be a potential therapeutic target. PMID:21335517

    African American women are at heightened risk for intimate partner violence (IPV) and its negative consequences, including health-compromising behaviors. Deliberate self-harm (DSH) is one clinically-relevant behavior that has been understudied among African American women generally and those with exposure to IPV in particular. To date, no studies have examined factors that may account for the relationship between IPV and DSH. Therefore, the goal of the present study was to examine the intercorrelations among IPV (physical, psychological, and sexual), PTSD, and DSH history and versatility, and the potentially mediating role of PTSD symptoms in the IPV-DSH relation. Participants were 197 African American community women currently experiencing IPV. Sixty participants (31%) reported a history of DSH. Among participants who reported DSH, there was an average endorsement of 2.3 unique forms of deliberate self-harm (i.e., DSH versatility). Significant positive associations were detected among physical IPV severity, psychological IPV severity, PTSD symptom severity, and DSH history and versatility. PTSD symptom severity mediated the relationships between physical and psychological IPV severity and DSH history and versatility. Results highlight the relevance of PTSD symptoms to DSH and suggest that treatments targeting PTSD symptoms may be useful in reducing DSH among IPV-exposed African American women. Copyright © 2014.

    Objective To assess the effect of local transfer ofplasmid-mediated inducible Nitric Oxide synthase gene using protein-coated metallic stents of inhibiting neointimal hyperplasia after coronary angioplasty. Methods The metallic stent was coated by cross-linked gelatin and mounted on 3.0 mm PTCA balloon,then endotoxin-free ultrapure plasmid pcDNA3hepiNOS was absorbed on the stent. Protein-coated stainless steel stents were used as controls. All stents were implanted into the middle segment of LAD. The ratio of balloon to vessel diameter was 1.1-1.3:1. Results At the 7th day after stenting, RT-PCR and immunohistochemical staining confirmed the expression of iNOS mRNA and presence of its protein at gene transferred vessels (n=2), but there was no expression in remote organs. After 3 months of stenting coronary angiograms showed that there was no restenosis in all animals transferred plasmid pcDNA3hepiNOS(n=5) while restenosis developed in all animals of the control group (n=5). Morphometric analysis showed that lumen diameter loss (0.61±0.30) mm vs (1.58±0.31) mm (P<0.001), residual lumen diameter (1.00±0.51) mm vs (0.36±0.32) mm (P<0.05), neointimal area (1.65±0.83) mm2 vs (2.83±0.83) mm2 (P<0.05), mean percentage of area stenosis (26.45±7.45) mm2 vs (94.2±14.3) mm2 (P<0.001) were significantly less than those in control group. The proportion of the neointimal area to media area(I/M) reduced to 59.84% in pcDNA3hepiNOS group. Conclusions Local plasmid-mediated human iNOS gene transferred with protein-coated metallic stents significantly inhibited intimal hyperplasia,which was usually a causative factor of retenosis after coronary angioplasty, in mini-swine model.%目的 为评价蛋白涂层金属支架携带质粒介导的诱导性一氧化氮合酶(iNOS)基因局部转染血管壁,预防冠状动脉内血管成形术后再狭窄的效果。方法 金属支架涂层为胶联明胶制成。载体为去内毒素纯化pcDNA3。采用标准球囊导管技

    Full Text Available Follicular mucinosis occurring along with angiolymphoid hyperplasia with eosinophils (ALHE has been described in a 54-year-old female. The patient presented with pruritic erythematous papules on the left frontoparietal scalp. Histopathological examination showed prominent blood vessels in the dermis lined by plump histiocytoid endothelial cells that were surrounded by a dense lymphoid infiltrate with numerous eosinophils; these findings are typical of angiolymphoid hyperplasia with eosinophils. Features of follicular mucinosis were observed in the same section with several hyperplastic follicular infundibula containing pools of mucin in the infundibular epithelium. The concurrent occurrence of these two distinct histopathological patterns in the same biopsy specimen has been described in only three cases to date.

    Due to intimal hyperplasia instent reobstruction in the femoropopliteal arterial segment is still an unsolved problem. Different techniques have been discussed in case of reintervention to guarantee longlasting patency rate. We conducted a randomized, controlled, pilot trial comparing Silverhawk atherectomy with percutaneous transluminal angioplasty (PTA) in patients with a first instent reobstruction in the femoropopliteal arterial segment, to evaluate intima media thickness (IMT) within the treated segment, as a parameter of recurrence of intimal hyperplasia. In a total 19 patients were included: 9 patients in the atherectomy device and 10 patients in the PTA arm. IMT within the treated segment was statistically significantly elevated in all patients treated with the Silverhawk device versus the patients treated with PTA. The obvious differentiation in elevation of IMT in nonfavor for patients treated with the Silverhawk device started at month 2 (max IMT SH 0.178 mm vs. IMT PTA 0.1 mm, p = 0.001) with a spike at month 5 (max IMT SH 0.206 mm vs. IMT PTA 0.145 mm, p = 0.003) and a decline once again at month 6 (max IMT SH 0.177 mm vs. IMT PTA 0.121 mm, p = 0.02). The values for mean IMT performed the same way. Although Silverhawk atherectomy provides good results at first sight, in the midterm follow-up of treatment of first instent restenosis it did not perform better than PTA as it showed elevated reoccurrence of intimal media hyperplasia.

    Focal nodular hyperplasia is an uncommon benign hepatic tumor that continues to pose diagnostic dilemmas. Imaging techniques are of great value in diagnosis of this tumor. In this article we present the US, CT, MR imaging, scintigraphy, and angiography findings. The demonstration of a central vascular scar is very helpful. Although the radiologic features may be diagnostic, many atypical cases must be differentiated from other benign or malignant hepatic tumors. In these cases excisional biopsy and histopathologic examination are necessary to determine a definite diagnosis. (orig.)

    Lymphatic vessels are important for maintenance of tissue fluid homeostasis and afferent antigen transport. In chronic inflammation, lymphangiogenesis takes place and is characterized by lymphatic endothelial cell proliferation and lymphatic hyperplasia. Vascular endothelial growth factor C (VEGFC) is the main known lymphangiogenic growth factor, and its expression is increased in periodontitis, a common chronic infectious disease that results in tissue destruction and alveolar bone loss. The role of lymphangiogenesis during development of periodontitis is unknown. Here, we test if transgenic overexpression of epithelial VEGFC in a murine model is followed by hyperplasia of lymphatic vessels in oral mucosa and if the lymphatic drainage capacity is altered. We also test if lymphatic hyperplasia protects against periodontal disease development. Transgenic keratin 14 (K14)-VEGFC mice had significant hyperplasia of lymphatics in oral mucosa, including gingiva, without changes in blood vessel vasculature. The basal lymph flow was normal but slightly lower than in wild-type mice when oral mucosa was challenged with lipopolysaccharide from Porphyromonas gingivalis. Under normal conditions, K14-VEGFC mice exhibited an increased number of neutrophils in gingiva, demonstrated enhanced phagocyte recruitment in the cervical lymph nodes, and had more alveolar bone when compared with their wild-type littermates. After induction of periodontitis, no strain differences were observed in the periodontal tissues with respect to granulocyte recruitment, bone resorption, angiogenesis, cytokines, and bone-related protein expressions or in draining lymph node immune cell proportions and vascularization. We conclude that overexpression of VEGFC results in hyperplastic lymphatics, which do not enhance lymphatic drainage capacity but facilitate phagocyte transport to draining lymph nodes. Hyperplasia of lymphatics does not protect against development of ligature-induced periodontitis.

    Pseudocarcinomatous hyperplasia of the fallopian tube is a rare, benign disease characterized by florid epithelial hyperplasia. The authors present the history and details of a 22-year-old woman with bilateral pelvic masses and a highly elevated serum CA-125 level (1,056 U/ml). Ultrasonography and magnetic resonance imaging (MRI) of the pelvis showed bilateral adnexal complex cystic masses with a fusiform or sausage-like shape. Contrast-enhanced fat-suppressed T1-weighted images showed enhancement of papillary projections of the right adnexal mass and enhancement of an irregular thick wall on the left adnexal mass, suggestive of tubal cancer. Based on MRI and laboratory findings, laparotomy was performed under a putative preoperative diagnosis of tubal cancer. The final pathologic diagnosis was pseudocarcinomatous hyperplasia of tubal epithelium associated with acute and chronic salpingitis in both tubes. The authors report a rare case of pseudocarcinomatous hyperplasia of the fallopian tubes mimicking tubal cancer.

    A prospective study was conducted to explore the relationship between childhood x-irradiation for lymphoid hyperplasia and the subsequent development of thyroid gland and other head and neck disorders. All individuals under 18 years of age who were x-irradiated for lymphoid hyperplasia during the years 1938-69 at Children's Hospital Medical Center, Boston comprised the exposed population. The comparison group consisted of non-exposed, surgically treated individuals. The study included a health questionnaire and a clinical examination component. A history of thyroid cancer was reported by 11 exposed subjects and no non-exposed subjects. Significantly elevated standardized incidence ratios of thyroid cancer were seen for both exposed males and females, 19.9 and 12.1, respectively. The average thyroid radiation dose was 25.8 rads and the mean latency period was 17.3 years

    2002-05-01

    Typical papillary hyperplasia, a recently recognized precursor lesion to low-grade papillary urothelial neoplasms, consists of undulating folds of cytologically benign urothelium. Well-developed, branching fibrovascular cores of a papillary neoplasm are not evident. We have noted lesions with the architectural pattern of papillary hyperplasia; however, the overlying urothelium demonstrated varying degrees of cytologic atypia. We identified 15 cases of atypical papillary hyperplasia (13 males, 2 females, age 55 to 92) with overlying urothelium showing cytologic atypia. Of these cases, 8 (53%) were received in consultation. Of the 15 cases, 8 exhibited overlying flat carcinoma in situ (CIS), 4 had overlying dysplasia, and 3 were transitional between papillary hyperplasia with atypia and the earliest lesions of papillary neoplasia. Of these cases, 5 patients had multiple specimens with atypical papillary hyperplasia (range, 2 to 8) over time. Concurrent to the diagnosis of atypical papillary hyperplasia, there were 25 different urothelial lesions: CIS (n = 11), papilloma (n = 1), papillary neoplasm of low malignant potential with CIS (n = 1), high-grade papillary urothelial carcinoma (n = 10; 3 with CIS), small-cell carcinoma (n = 1), and infiltrating urothelial carcinoma (n = 1). Of 11 patients with known prior history, 2 had 12 prior urothelial neoplasms (9 low-grade papillary neoplasms, 2 papillary urothelial neoplasms of low malignant potential, and 1 high-grade papillary cancer). Of 10 patients with atypical papillary hyperplasia and a minimum of 1 year of follow-up, 9 had 19 recurrences: CIS (n = 4), papilloma (n = 1), papillary neoplasm of low malignant potential (n = 1), infiltrating urothelial carcinoma (n = 3; 1 with CIS), and high-grade papillary urothelial carcinoma (n = 10; 5 with invasion and 2 with CIS). Whether the papillary hyperplasia had overlying CIS or dysplasia did not affect the correlation with urothelial neoplasms. Immunohistochemical analysis

  3. Pituitary hyperplasia: a complication of the pseudomalabsorption of thyroxine

    Full Text Available Mary-Anne Doyle, Heather A Lochnan Division of Endocrinology, University of Ottawa, Ottawa, ON, Canada Objective: “The pseudomalabsorption of thyroxine” has been used to describe patients with hypothyroidism who fail to comply with their treatment. We describe a unique case of a 32-year-old with hypothyroidism who developed pituitary hyperplasia and hyperprolactinemia secondary to the pseudomalabsorption of thyroxine. Investigations and treatment: After baseline thyroid-function tests were performed, the patient was administered levothyroxine 0.5 mg under the supervision of a registered nurse. Thyroid function testing was repeated at 30, 60, 120, and 180 minutes. Arrangements were made for further daily supervised loading of levothyroxine 0.1 mg. Results: With the administration of 0.5 mg levothyroxine, free thyroxine levels increased by 120 minutes, and with daily supervised dosing of 0.1 mg there was normalization of the thyroid hormone levels and a reduction of thyroid-stimulating hormone levels. Maintenance of thyroid-stimulating hormone < 15 mU/L for 2 weeks led to a reduction in prolactin levels and regression in the size of the pituitary on magnetic resonance imaging. Conclusion: If left untreated, these patients face significant morbidity and are at risk of developing pituitary hyperplasia, complications from an increase in pituitary size, hyperprolactinemia, and potentially myxedema coma. Recognizing pituitary hyperplasia and hyperprolactinemia as a complication from the pseudomalabsorption of levothyroxine may prevent the potential of a misdiagnosis of a prolactinoma leading to unnecessary investigations and inappropriate treatment. Patient awareness of this serious complication and the rapid, demonstrable resolution with adequate thyroid hormone replacement may provide motivation to comply with supervised dosing of levothyroxine. It has also been suggested that supervised treatment enables the individual to maintain their patient

    Full Text Available Background/Aim. Nocturia often occurs in patients with benign prostate hyperplasia (BPH. The aim of the study was to investigate the frequency of nocturia in patients with BPH. Nocturia and other factors associated with it were also investigated. Methods. Forty patients with the confirmed diagnosis of BPH were studied. Transurethral and transvesical prostatectomy were performed in all the patients. Symptoms were evaluated with the International Prostate Symptom Score before, as well as three and six months after the surgery. All the results were compared with the control group. Results. There was no statistically significant difference between the patients before and after the surgery regarding nocturia. There was, however, a statistically significant difference between the operated patients and the control group regarding nocturia, as well as a statistically significant correlation between noctruia and the age of the patients in both the investigated and the control group. A correlation also existed between nocturia and the prostatic size. Conclusion. There was no statistically significant improvement in symptoms of nocturia after the surgery. It is necessary to be very careful in decision making in patients with nonabsolute indiction for surgery and isolated bothersome symptom of nocturia. Age of a patient should also be considered in the evaluation of favorable result of the surgery because of a significant correlation between noctura and the age of a patient.

    Due to intimal hyperplasia instent reobstruction in the femoropopliteal arterial segment is still an unsolved problem. Different techniques have been discussed in case of reintervention to guarantee longlasting patency rate. We conducted a randomized, controlled, pilot trial comparing Silverhawk atherectomy with percutaneous transluminal angioplasty (PTA) in patients with a first instent reobstruction in the femoropopliteal arterial segment, to evaluate intima media thickness (IMT) within the treated segment, as a parameter of recurrence of intimal hyperplasia. In a total 19 patients were included: 9 patients in the atherectomy device and 10 patients in the PTA arm. IMT within the treated segment was statistically significantly elevated in all patients treated with the Silverhawk device versus the patients treated with PTA. The obvious differentiation in elevation of IMT in nonfavor for patients treated with the Silverhawk device started at month 2 (max IMT SH 0.178 mm vs. IMT PTA 0.1 mm, p = 0.001) with a spike at month 5 (max IMT SH 0.206 mm vs. IMT PTA 0.145 mm, p = 0.003) and a decline once again at month 6 (max IMT SH 0.177 mm vs. IMT PTA 0.121 mm, p = 0.02). The values for mean IMT performed the same way. Although Silverhawk atherectomy provides good results at first sight, in the midterm follow-up of treatment of first instent restenosis it did not perform better than PTA as it showed elevated reoccurrence of intimal media hyperplasia.

    Focal epithelial hyperplasia (FEH) or Heck's disease is a rare viral infection of the oral mucosa caused by human papilloma virus especially subtypes 13 or 32. The frequency of this disease varies widely from one geographic region and ethnic groups to another. This paper reports an Iranian case of extensive focal epithelial hyperplasia. A 35-year-old man with FEH is described, in whom the lesions had persisted for more than 25 years. The lesion was diagnosed according to both clinical and histopathological features. Dental practitioner should be aware of these types of lesions and histopathological examination together and a careful clinical observation should be carried out for a definitive diagnosis.

    Red pigment tattoos are known to cause pseudoepitheliomatous hyperplasia in the skin, frequently simulating squamous cell carcinoma or keratoacanthoma. Herein, the authors present two additional cases of red pigment tattoo pseudoepitheliomatous hyperplasia in which they noted a lichenoid tissue reaction. They reviewed the previously published cases and observed a lichenoid reaction in the histopathological images similar to hypertrophic lichen planus. The authors suggest that these reactions might best be referred to as “lichenoid reaction with pseudoepitheliomatous hyperplasia” or “hypertrophic lichen planus-like reaction.” Accordingly, recognition of an inflammatory component may allow additional treatment options.

    We report hereditary pituitary hyperplasia. The objective of the study was to describe the results of the clinical and laboratory analysis of this rare instance of hereditary pituitary hyperplasia. The study is a retrospective analysis of three cases from one family. The study was conducted at the National Institutes of Health, a tertiary referral center. A mother and both her sons had very early-onset gigantism associated with high levels of serum GH and prolactin. The condition was treated by total hypophysectomy. We performed clinical, pathological, and molecular evaluations, including evaluation basal and provocative endocrine testing, neuroradiological assessment, and assessment of the pituitary tissue by microscopic evaluation, immunohistochemistry, and electron microscopy. All three family members had very early onset of gigantism associated with abnormally high serum levels of GH and prolactin. Serum GHRH levels were not elevated in either of the boys. The clinical, radiographic, surgical, and histological findings indicated mammosomatotroph hyperplasia. The pituitary gland of both boys revealed diffuse mammosomatotroph hyperplasia of the entire pituitary gland without evidence of adenoma. Prolactin and GH were secreted by the same cells within the same secretory granules. Western blot and immunohistochemistry demonstrated expression of GHRH in clusters of cells distributed throughout the hyperplastic pituitary of both boys. This hereditary condition seems to be a result of embryonic pituitary maldevelopment with retention and expansion of the mammosomatotrophs. The findings suggest that it is caused by paracrine or autocrine pituitary GHRH secretion during pituitary development.

    Full Text Available The limbic brain appears to be the source of basic emotions and urges. In contrast the neocortex gives humans the ability to think in abstract and symbolic terms and to use language. Emotions by neural projections from the limbic system to neocortex influence all aspect of cognition, from perception to rational decision making. Although the cases whose intellectual and motor abilities appeared fully functional, decision making ability and emotional processing impaired together after a damage to the ventromedial prefrontal lobes suggest that the emotions had priority in the brain processing. The effectiveness of the psychotherapy is thought to be related to the left prefrontal cortex activity. The rational decisions are changing easily under the stressful moments and experiencing the same problems over and over again. This concept may explain why the couples under the stressful conditions may easily fall into radicalism, and decide that they are right but the others wrong. The specific kinds of conflict behaviors between couples like the criticism, contempt, defensiveness and stonewalling are correlated with the physical signs of the amygdala activation. For this reason, before the people to engage new forms of thought and behavior must notice and change the emotional processes. In the light of these concepts in addition the cognitive and behavioral approach, it would not be wrong to think that the therapy working with the emotional techniques will be more successful.

    Benign prostatic hyperplasia is a common disease in over 50 years-old men consisting in uncontrolled and benign growth of prostatic gland that leads to lower urinary tract symptoms. The etiology of benign prostatic hyperplasia is multifactoral involving the increased conversion of testosterone in dihydrotestosterone by the prostatic 5α-reductase action, which brought about events that encourage the prostate growth (static component) and the increase of the bladder and prostate smooth muscle tone (dynamic component) regulated by the aα 1 -adrenoceptors (ADR). The pharmacological treatment of the benign prostatic hyperplasia includes the prostatic 5aα-reductase inhibitors, the aα 1 -adrenoreceptor blockers, their combined therapy and the phytotherapy. This paper was aimed at presenting the most relevant aspects of the pharmacology of drugs used for treating the benign prostatic hyperplasia, and providing elements to analyze their efficacy, safety and tolerability. To this end, a review was made of the different drugs for the treatment of this pathology and they were grouped according to their mechanism of action. Natural products were included as lipid extracts from Serenoa repens and Pygeum africanum as well as D-004, a lipid extract from Roystonea regia fruits, with proved beneficial effects on the main etiological factors of benign prostatic hyperplasia. D-004 is a prostatic 5a-reductase inhibitor, an aα 1 -adrenoceptor antagonist, aα 5-lipooxygenase inhibitor and has antioxidant action, all of which reveals a multifactoral mechanism. The results achieved till now indicate that D-004 is a safe and well-tolerated product

    Full Text Available PURPOSE: To investigate the effects of alpha-1 adrenergic receptor antagonists for the treatment of benign prostatic hyperplasia (BPH regarding potential risks of complications in the setting of cataract surgery. AIM: To address recommendations, optimal control therapy, voiding symptoms and safety within the setting of cataract surgery. MATERIALS AND METHODS: A comprehensive literature review was performed using MEDLINE with MeSH terms and keywords "benign prostatic hyperplasia", "intraoperative floppy iris syndrome", "adrenergic alpha-antagonist" and "cataract surgery". In addition, reference lists from identified publications were reviewed to identify reports and studies of interest from 2001 to 2009. RESULTS: The first report of intraoperative floppy iris syndrome (IFIS was observed during cataract surgery in patients taking systemic alpha-1 AR antagonists in 2005. It has been most commonly seen related to use of tamsulosin. Changes of medication and washout periods of up to 2 weeks have been attempted to reduce the risk of complications in the setting of cataract surgery. CONCLUSION: Patients under clinical treatment for BPH should be informed about potential risks of this drug class so that it can be discuss with their healthcare providers, in particular urologist and ophthalmologist, prior to cataract surgery.

    This study was carried out to determine the underestimation rate of carcinoma upon surgical biopsy after a diagnosis of flat epithelial atypia and atypical ductal hyperplasia and 11-gauge vacuum-assisted breast biopsy. A retrospective review was conducted of 476 vacuum-assisted breast biopsy performed from May 2005 to January 2007 and a total of 70 cases of atypia were identified. Fifty cases (71%) were categorized as pure atypical ductal hyperplasia, 18 (26%) as pure flat epithelial atypia and two (3%) as concomitant flat epithelial atypia and atypical ductal hyperplasia. Each group were compared with the subsequent open surgical specimens. Surgical biopsy was performed in 44 patients with atypical ductal hyperplasia, 15 patients with flat epithelial atypia, and two patients with flat epithelial atypia and atypical ductal hyperplasia. Five cases of atypical ductal hyperplasia were upgraded to ductal carcinoma in situ, three cases of flat epithelial atypia yielded one ductal carcinoma in situ and two cases of invasive ductal carcinoma, and one case of flat epithelial atypia/atypical ductal hyperplasia had invasive ductal carcinoma. The overall rate of malignancy was 16% for atypical ductal hyperplasia (including flat epithelial atypia/atypical ductal hyperplasia patients) and 20% for flat epithelial atypia. The presence of flat epithelial atypia and atypical ductal hyperplasia at biopsy requires careful consideration, and surgical excision should be suggested.

    Full Text Available Clinical benign prostatic hyperplasia (BPH is one of the most common diseases in ageing men and the most common cause of lower urinary tract symptoms (LUTS. The prevalence of BPH increases after the age of 40 years, with a prevalence of 8%–60% at age 90 years. Some data have suggested that there is decreased risk among the Asians compared to the western white population. Genetics, diet and life style may play a role here. Recent reports suggest the strong relationship of clinical BPH with metabolic syndrome and erectile dysfunction, as well as the possible role of inflammation as a cause of the prostatic hyperplasia. Lifestyle changes including exercise and diet are important strategies in controlling this common ailment.

    Tumor suppressor phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is a lipid phosphatase that regulates multiple cellular processes including cell polarity, migration, proliferation, and carcinogenesis. In this work, we demonstrate that conditional deletion of Pten (PtenΔ/Δ) in the respiratory epithelial cells of the developing mouse lung caused epithelial cell proliferation and hyperplasia as early as 4 to 6 weeks of age. While bronchiolar cell differentiation was normal, as in...

    Saw palmetto is used by over 2 million men in the United States for the treatment of benign prostatic hyperplasia and is commonly recommended as an alternative to drugs approved by the Food and Drug Administration. In this double-blind trial, we randomly assigned 225 men over the age of 49 years who had moderate-to-severe symptoms of benign prostatic hyperplasia to one year of treatment with saw palmetto extract (160 mg twice a day) or placebo. The primary outcome measures were changes in the scores on the American Urological Association Symptom Index (AUASI) and the maximal urinary flow rate. Secondary outcome measures included changes in prostate size, residual urinary volume after voiding, quality of life, laboratory values, and the rate of reported adverse effects. There was no significant difference between the saw palmetto and placebo groups in the change in AUASI scores (mean difference, 0.04 point; 95 percent confidence interval, -0.93 to 1.01), maximal urinary flow rate (mean difference, 0.43 ml per minute; 95 percent confidence interval, -0.52 to 1.38), prostate size, residual volume after voiding, quality of life, or serum prostate-specific antigen levels during the one-year study. The incidence of side effects was similar in the two groups. In this study, saw palmetto did not improve symptoms or objective measures of benign prostatic hyperplasia.

    Rubio-Puchol, O; Garzón-Pastor, S; Salom-Vendrell, C; Hernández-Mijares, A

    Unilateral adrenal hyperplasia is a rare cause of primary hyperaldosteronism (around a 3%) that has surgical treatment. A case of a patient with hypertension resistant to conventional therapy in treatment with 7 drugs who presented with primary hyperaldosteronism due to unilateral adrenal hyperplasia is presented. A left adrenalectomy was performed, and the patient had a good clinical response, with no need of any drug after 2 years of surgery. Unilateral adrenal hyperplasia is a different entity and it is not an asymmetric variant of the bilateral adrenal hyperplasia. In the study of patients with primary hyperaldosteronism and imaging tests with absence of adenoma is a diagnosis that must be considered before cataloguing patients with bilateral adrenal hyperplasia and start a medical treatment, because unilateral adrenal hyperplasia would have a surgical resolution.

    because of fear of intimate partner violence. Conclusion Intimate partner violence is common in eastern Uganda and is related to gender inequality, multiple partners, alcohol, and poverty. Accordingly, programmes for the prevention of intimate partner violence need to target these underlying factors. The suggested link between intimate partner violence and HIV risky behaviours or prevention strategies calls for further studies to clearly establish this relationship.

    Denture hyperplasia is a reactive lesion of the oral mucosa, usually associated to an ill-fitting denture. This lesion is easily diagnosed and in some cases distinct microscopic variations such as osseous, oncocytic and squamous metaplasia may be found. These metaplastic alterations probably are associated with the lymphocytic infiltrate usually present in denture hyperplasia. We present a case of denture hyperplasia containing salivary gland tissue with ductal alterations mimicking an oral inverted ductal papilloma.

The visual fields returned to normal. This is a case of pituitary hyperplasia due to primary hypothyroidism

  10. Urodynamic implications of benign prostatic hyperplasia

    DEFF Research Database (Denmark)

    Jensen, K M; Andersen, J T

    1990-01-01

    By the age of 60, about 70% of men have developed benign prostatic hyperplasia (BPH), and 85%-95% of these have symptomatic dysfunction of the lower urinary tract, 10%-20% undergoing prostatectomy. Although transurethral resection of the prostate is generally considered to be a safe and effective...... instability has no bearing on the postoperative result. Measurement of urinary flow, in contrast, is of predictive value in BPH, patients in whom the maximum urinary flow before surgery is more than 15 ml/s having significantly worse results of surgery than those with a maximum urinary flow of less than 15 ml...

  11. Prenatal Diagnosis of Congenital Adrenal Hyperplasia.

    2016-06-01

    Congenital adrenal hyperplasia (CAH) owing to 21-hydroxylase deficiency is a monogenic disorder of adrenal steroidogenesis. To prevent genital ambiguity, in girls, prenatal dexamethasone treatment is administered early in the first trimester. Prenatal genetic diagnosis of CAH and fetal sex determination identify affected female fetuses at risk for genital virilization. Advancements in prenatal diagnosis are owing to improved understanding of the genetic basis of CAH and improved technology. Cloning of the CYP21A2 gene ushered in molecular genetic analysis as the current standard of care. Noninvasive prenatal diagnosis allows for targeted treatment and avoids unnecessary treatment of males and unaffected females. Copyright © 2016 Elsevier Inc. All rights reserved.

  12. Interleukin-1/toll-like receptor-induced nuclear factor kappa B signaling participates in intima hyperplasia after carotid artery balloon injury in goto-kakizaki rats: a potential target therapy pathway.

    Directory of Open Access Journals (Sweden)

    Xiaotian Zhang

    Full Text Available The value of restenosis after percutaneous coronary intervention (PCI is recognized worldwide, especially for diabetic patients. Interleukin-1/Toll-like receptor (IL-1/TLR signaling is involved in innate and adaptive immune responses, but whether and how the IL-1/TLR-induced nuclear factor kappa B (NFκB pathway plays key roles in intimal formation is unclear. The underlying mechanism of intima hyperplasia was investigated with a model of carotid balloon injury in Goto-Kakizaki (GK and Wistar rats and with lipopolysaccharide-stimulated macrophages. Elastic-van Gieson staining showed the medial area peakedon Day 3 post-injury and decreased by Day 7 post-injury in both GK and Wistar rats. The N/M at Day 7 in GK rats was significantly higher than in Wistar rats (p<0.001. The percent of 5-ethynyl-2'-deoxyuridine (EdU staining-positive cells on Day 3 post-injury was greater than seen on Day 7 post-injury in GK and Wistar rats. The percent of EdU-positive cells on Days 3 and 7 post-injury in Wistar rats was less than that found in GK rats (p<0.01; p<0.05. NFκBp65 immunostaining had increased by Day 7 post-injury. Agilent Whole Genome Oligo Microarray verified that the IL-1/TLR-induced NFκB pathway was activated by carotid balloon injury. TLR4, IL-1 receptor associated kinase, inhibitors α of NFκB, human antigen R, c-Myc (Proto-Oncogene Proteins, EGF-like module-containing mucin-like hormone receptor-like 1 and Interleukin-6 were up-regulated or down-regulated according to immunochemistry, quantitative real-time PCR, Western blotting and Enzyme linked immunosorbent assay. Overall, we conclude that the IL-1/TLR-induced NFκB pathway participates in the intimal hyperplasia after carotid injury in GK and Wistar rats and that GK rats respond more intensely to the inflammation than Wistar rats.

    Full Text Available Focal nodular hyperplasia is a benign liver lesion incidentally discovered with increasing frequency because of the proliferation of imaging studies. Radiographic characterization can diagnose this pathologic lesion and nonoperative therapy is the standard of care. However, surgical resection may be required for diagnostic reasons or symptomatic patients. Depending on the anatomic location of the lesion, biopsy and/or resection can be performed laparoscopically. We herein report the case of a 26-year-old Japanese woman with a hepatic tumor who required a medical examination. Her medical history was negative for alcohol abuse, oral contraceptive administration and trauma. Clinical examination showed no significant symptoms. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass located in the left lateral segment of the liver with a diameter of about 40 mm. It was difficult to diagnose the tumor definitively from these imaging studies, so we performed laparoscopic partial hepatectomy with successive firing of endoscopic staplers. The histopathological diagnosis was focal nodular hyperplasia. Surgical procedures and postoperative course were uneventful and the patient was discharged from the hospital on postoperative day 5.

    Tumor suppressor phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is a lipid phosphatase that regulates multiple cellular processes including cell polarity, migration, proliferation, and carcinogenesis. In this work, we demonstrate that conditional deletion of Pten (Pten(Delta/Delta)) in the respiratory epithelial cells of the developing mouse lung caused epithelial cell proliferation and hyperplasia as early as 4 to 6 weeks of age. While bronchiolar cell differentiation was normal, as indicated by beta-tubulin and FOXJ1 expression in ciliated cells and by CCSP expression in nonciliated cells, cell proliferation (detected by expression of Ki-67, phospho-histone-H3, and cyclin D1) was increased and associated with activation of the AKT/mTOR survival pathway. Deletion of Pten caused papillary epithelial hyperplasia characterized by a hypercellular epithelium lining papillae with fibrovascular cores that protruded into the airway lumens. Cell polarity, as assessed by subcellular localization of cadherin, beta-catenin, and zonula occludens-1, was unaltered. PTEN is required for regulation of epithelial cell proliferation in the lung and for the maintenance of the normal simple columnar epithelium characteristics of bronchi and bronchioles.

    2007-12-01

    This article examines adolescent intimacy through a developmental lens. As they age, adolescents develop the relational skills necessary to gain independence from their parents and form intimate relationships with friends and romantic partners. This article details how adolescents' intimate relationships expand from parental connections to encompass friendships, dating, and sexual activity during progressing stages of development. Finally, clinical implications for adolescent health care practitioners for promoting intimacy and healthy relationships are suggested.

    To assess the influence of stent design [interlacing (type A) vs. crossing method (type B)] on neointimal hyperplasia using a self-expandable nitinol stent, which crosses the side branches of the abdominal aorta. In seven mongrel dogs, nitinol stents with type A and B intersections were placed in the abdominal aorta across the main branches: 4 Niti-Ms and 3 Niti-Ds. Two months after the stent placement, a DSA was performed for a stent patency evaluation, followed by the extraction of the aortas. The degree of neointimal formation along the wire was evaluated by calculating the area ratio of intimal hyperplasia (type A vs. B). A Student's t-test was employed to investigate the differences in the neointimal hyperplasia between blood types A and B. The total number of wire intersections overlain at the ostia branch ostia was 23 for type A and 36 for type B. The area ratio of the neointimal hyperplasia, for a given area, was 29.09 {+-} 10.82% (type A) and 13.80 {+-} 6.94% (type B) ({rho} < 0.0001)]. Furthermore, the area ratios of the neointimal hyperplasia per area of stent-wire in the given area were 138.38 {+-} 10.84% (type A). 87.58 {+-} 7.36% (type B) ({rho} = 0.0002). In conclusion the interlacing pattern vs. the crossing pattern showed a higher level of neointimal formation than the crossing pattern.

Silodosin, (--1-(3-hydroxypropyl-5-[(2R-2-({2-[2-(2,2,2trifluoroethoxy phenoxy]ethyl}aminopropyl]-2,3-dihydro-1H-indole-7- carboxamide, is a new α1A-AR selective antagonist. Silodosin is highly selective for the α1A-AR subtype, showing an affinity for the α1A-AR that is 583- and 55.5-fold higher than its affinity for the α1B- and α1D-ARs, respectively. In randomized, double-blind, placebo-controlled phase III studies performed in Japan and the United States, silodosin has been shown to be effective for both storage and voiding symptoms associated with benign prostatic hyperplasia. Early effects of silodosin (after 2–6 hours or day 1 on lower urinary tract symptoms have also been reported. In urodynamic studies, detrusor overactivity disappeared in 40% and improved in 35% of patients after administration. In pressure flow studies, the grade of obstruction on the International Continence Society nomogram showed improvement in 56% of patients. The rate of adverse events in the silodosin, tamsulosin and placebo groups was 88.6%, 82.3%, and 71.6%, respectively. The most common adverse event was (mostly mild abnormal ejaculation (28.1%. However, few patients (2.8% discontinued silodosin because of abnormal ejaculation. Orthostatic hypotension showed a similar incidence in the silodosin (2.6% and placebo (1.5% groups. In conclusion, silodosin improves detrusor overactivity and obstruction and thus may be effective for both storage and voiding

    Fibroadenomatoid hyperplasia of the breast (FAHB) is a rare benign breast lesion and its clinical features are similar to fibroadenoma and fibrocystic changes. FAHB has been previously termed sclerosing lobular hyperplasia, fibroadenomatosis, fibroadenomatoid change, or fibroadenomatoid mastopathy. Typically, FAHB is derived from stroma and epithelia. The pathologic characteristics of FAHB are microfocal lobulocentric proliferation of stroma accompanied by epithelial and myoepithelial components resembling similar histological changes, as found in fibroadenoma, apocrine hyperplasia, intraductal hyperplasia, and lobular hyperplasia. FAHB could be present as a localized or diffused pattern in pathology. Most cases show no well-circumscribed mass lesions and no apparent capsules; it is usually identified as an incidental finding in other benign lesions or in random sampling in cancerous breast tissues. FAHB is categorized as a benign proliferative breast disease and it has previously been reported; however, the authors believe this study may be the first case with two giant masses reported. Fiber adenoma hyperplasia is a rare cystic hyperplasia of breast pathology and its ultrasonographic manifestations are easily confused with breast cancer. Comparative MRI ultrasound analysis will help make the differential diagnosis. © 2014 S. Karger AG, Basel.

    Gong, Edward M; Gerber, Glenn S

    2004-01-01

    Benign prostatic hyperplasia (BPH) is a common health issue that affects 8% of all men at the age of 40, 60% of men in their 70s, and 90% of those greater than 80 years of age. One-fourth of these men will develop moderate to severe lower urinary tract symptoms that greatly affect their quality of life. Recent evidence suggests that the use of saw palmetto leads to improvements in urinary function for those suffering from BPH. The favorable comparison of saw palmetto with tamsulosin, a well-known first line agent in the treatment of urinary tract symptoms, demonstrates promise towards a beneficial effect of this herbal agent, with very few, if any, adverse effects. However, what degree of this beneficial activity is due to placebo effects is yet to be determined. In addition, the precise mechanism of action of saw palmetto in men with BPH remains unclear.

    Mesothelial papillary hyperplasia (MPH) has been described as an incidental finding on the epicardial surface of clinically normal laboratory Beagle dogs. We describe MPH in 4 dogs diagnosed with acute cardiac tamponade (1 case) or chronic cardiac disease (3 cases). Cardiac MPH appeared as distinct, soft, irregular villous plaques on the epicardial surface of the auricles and occasionally the ventricles. Histologically, areas of MPH were composed of multiple papillary fronds arising from the epicardial surface and projecting into the pericardial space. Fronds were covered by cuboidal and occasionally vacuolated mesothelial cells and were supported by loose fibrovascular stroma with various degrees of edema and inflammation. Although these may represent incidental findings with no clinical significance, the gross appearance warrants differentiation from other conditions. Additional insight into the pathogenesis of MPH is needed to fully understand its significance in the face of concurrent cardiac disease.

    Full Text Available Congenital adrenal hyperplasia (CAH describes a group of autosomal recessive disorders where there is impairment of cortisol biosynthesis. CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment of CAH. The optimal treatment for adults with CAH continues to be a challenge. Important long-term health issues for adults with CAH affect both men and women. These issues may either be due to the disease or to steroid treatment and may affect final height, fertility, cardiometabolic risk, bone metabolism, neuro-cognitive development and the quality-of-life. Patients with CAH should be regularly followed-up from childhood to adulthood by multidisciplinary teams who have knowledge of CAH. Optimal replacement therapy, close clinical and laboratory monitoring, early life-style interventions, early and regular fertility assessment and continuous psychological management are needed to improve outcome.

    SUMMARY Blood platelets provide the initial response to vascular endothelial injury, becoming activated as they adhere to the injured site. Activated platelets recruit leukocytes, and initiate proliferation and migration of vascular smooth muscle cells (SMC) within the injured vessel wall, leading to development of neointimal hyperplasia. Endothelial CD39/NTPDase1 and recombinant solCD39 rapidly metabolize nucleotides, including stimulatory ADP released from activated platelets, thereby suppressing additional platelet reactivity. Using a murine model of vascular endothelial injury, we investigated whether circulating human solCD39 could reduce platelet activation and accumulation, thus abating leukocyte infiltration and neointimal formation following vascular damage. Intraperitoneally-administered solCD39 ADPase activity in plasma peaked 1 hr post-injection, with an elimination half-life of 43 hr. Accordingly, mice were administered solCD39 or saline 1 hr prior to vessel injury, then either sacrificed 24 hr post-injury or treated with solCD39 or saline (3X weekly) for an additional 18 days. 24 hr post-injury, solCD39-treated mice displayed a reduction in platelet activation and recruitment, P-selectin expression, and leukocyte accumulation in the arterial lumen. Furthermore, repeated administration of solCD39 modulated the late stage of vascular injury by suppressing leukocyte deposition, macrophage infiltration and SMC proliferation/migration, resulting in abrogation of neointimal thickening. In contrast, injured femoral arteries of saline-injected mice exhibited massive platelet thrombus formation, marked P-selectin expression, and leukocyte infiltration. Pronounced neointimal growth with macrophage and SMC accretion was also observed (intimal-to-medial area ratio 1.56±0.34 at 19 days). Thus, systemic administration of solCD39 profoundly affects injury-induced cellular responses, minimizing platelet deposition and leukocyte recruitment, and suppressing

The facial bones, except for the mandible and orbits, are usually not involved. We report an unusual case of a 28-month-old black boy with SCA who presented with extensive marrow hyperplasia of the maxillary sinuses in addition to severe calvarial and mandibular changes. The imaging characteristics on CT (similar to other sites of marrow hyperplasia) and MR (low signal on both T 1 and T 2 sequences) should aid in making the correct diagnosis. (orig.)

    We herein report a case of the breast fibroadenoma with foci of so-called immature variant of the conventional ductal hyperplasia. This type of usual ductal hyperplasia is histologically characterised by encircling intraductal proliferation of large cells with pale to amphophilic cytoplasm and large nuclei which vary in shape and in staining quality of the chromatin. We showed here, using the cytokeratin immunohistochemistry, that the proliferating cells were not of immature but rather mature immunohistochemical phenotype. Because of the presented discordance between immature histology and mature immunohistological profile we suggest that this rare type of usual ductal hyperplasia should be called "immature-like".

    Benign prostatic hyperplasia (BPH) is characterized by an enlargement of the prostate, causing lower urinary tract symptoms in elderly men worldwide. However, the molecular mechanism underlying the pathogenesis of BPH is unclear. Anoctamin1 (ANO1) encodes a Ca(2+)-activated chloride channel (CaCC) that mediates various physiological functions. Here, we demonstrate that it is essential for testosterone-induced BPH. ANO1 was highly amplified in dihydrotestosterone (DHT)-treated prostate epithelial cells, whereas the selective knockdown of ANO1 inhibited DHT-induced cell proliferation. Three androgen-response elements were found in the ANO1 promoter region, which is relevant for the DHT-dependent induction of ANO1. Administration of the ANO1 blocker or Ano1 small interfering RNA, inhibited prostate enlargement and reduced histological abnormalities in vivo. We therefore concluded that ANO1 is essential for the development of prostate hyperplasia and is a potential target for the treatment of BPH.

    2009-01-01

    Full Text Available Intravascular papillary endothelial hyperplasia is a benign nonneoplastic vascular lesion that consists of endothelial cells with abundant vascular tissue with papillary proliferation. An adult female had a painless growing dark red nodule on the left side of the lower lip and often touched and gnawed at it for more than 4 years. The lesion was a tender, smooth mass approximately 1 cm in diameter without discoloration reaction. Magnetic resonance imaging of the lesion showed specific findings. She was diagnosed clinically as having mimicked hemangioma, and the lesion was totally excised under local anesthesia. Histopathological examination revealed that papillary proliferated endothelial cells with venous pool, and the lesion was diagnosed as intravascular papillary endothelial hyperplasia associated with venous pool. There has been no recurrence for more than 1 year. Despite the benign nature of this lesion, it could have been mistaken for a malignant tumor because of its clinical course and radiologic findings.

    To describe the prevalence of intimate partner violence (IPV) in Spain in the last year and at some point during the lifetime, to determine health status in women according to whether they had experienced IPV or not, and to analyze the individual variables associated with IPV in Spain. A cross-sectional study was performed of the database, Macrosurvey on Gender Violence in Spain 2011. This database includes data on 7,898 women older than 18 years old. The dependent variables were IPV-last year, IPV-ever in life. Covariates consisted of sociodemographic characteristics, socioeconomic status, maternal experience of IPV, social support, and self-care. The measure of association used was the OR with its 95% confidence interval (95% CI). A total of 3.6% of women had experienced IPV-last year and 12.2% ever in life. Female victims of IPV had poorer health than women who had not experienced IPV. Immigrant women living in Spain for 6 years or more were more likely to experience IPV-ever in life than Spanish women [OR (95% CI): 1.95 (1.50, 2.53)]. An interaction was found between nationality and the existence of children under 18 years old. Among women with children under 18 years old, immigrant women were more likely to experience IPV-last year than Spanish women [OR (95% CI): 1.99 (1.25, 3.17)]. Other variables associated with IPV were age, low socioeconomic status, low social support and having a mother who had experienced IPV. In Spain, some women have a higher probability of experiencing IPV. The variables associated with greater vulnerability to IPV should be taken into account when implementing measures to prevent or alleviate IPV. Copyright © 2013 SESPAS. Published by Elsevier Espana.

    Full Text Available Adenomyomatous hyperplasia is rarely found in the extrahepatic bile duct. A 54-year-old man was referred to our center with a diagnosis of extrahepatic bile duct stenosis which had been detected by endoscopic retrograde choloangiopancreatography. Abdominal computed tomography revealed thickening of the wall of the middle extrahepatic bile duct, however no malignant cells were detected by cytology. Since bile duct carcinoma could not be ruled out, we performed resection of the extrahepatic duct accompanied by lymph node dissection. Histopathologically, the lesion was diagnosed as adenomyomatous hyperplasia of the extrahepatic bile duct. Present and previously reported cases showed the difficulty of making a diagnosis of adenomyomatous hyperplasia of the extrahepatic bile duct preoperatively or intraoperatively. Therefore, when adenomyomatous hyperplasia is suspected, a radical surgical procedure according to malignant disease may be necessary for definitive diagnosis.

    Objective: To analyze the MRI manifestations of the pituitary hyperplasia due to primary hypothyroidism and to improve the differential diagnosis of secondary pituitary hyperplasia and pituitary tumors. Methods: The MRI findings of pituitary hyperplasia in 10 documented primary hypothyroidism patients (male 3, female 7; age range: 9-15 years) were reviewed. The pulse sequences using a 1.0T MR scanner included coronal and sagittal T 1 W, coronal T 2 W and coronal contrast-enhanced T 1 W in all patients. Results: The pituitary gland was markedly enlarged with mean height of 15.5 mm (11-23 mm). Central bulging of pituitary gland was seen in all 10 patients with mild displacement of the infundibulum in 3 and sellar enlargement in 5. All glands had homogeneous MR signal intensities and contrast enhancement. Conclusion: Pituitary hyperplasia due to primary hypothyroidism has characteristic MR features of central bulging with homogeneous signal intensities and contrast enhancement. (authors)

    Typology of incarcerated intimate partner aggressors. People who engage in intimate partner violence do not constitute a homogeneous group. Many studies in the Anglo-Saxon countries back the possibility of differentiating several subtypes of aggressors, but there are differences among them. One of the main applications of these typologies is the adaptation of the treatments to the subjects' characteristics. The aim of the present pilot study was to empirically establish a typology of batterers in Spain. The sample of 50 convicted violent intimate partner offenders was obtained from the Brians-2 penitentiary (Barcelona). Self-esteem, anger, cognitive distortions, and personality disorders were evaluated, as well as the frequency and type of violence. The results suggest the existence of two subtypes, distinguishable on the basis of the predictive dimensions, and so, partially confirm the typological proposals.

    Cushing\\'s disease is very rare in the paediatric population. Although uncommon, corticotroph hyperplasia causing Cushing\\'s syndrome has been described in the adult population, but appears to be extremely rare in children. Likewise, cyclical cortisol hypersecretion, while accounting for 15 % of adult cases of Cushing\\'s disease, has only rarely been described in the paediatric population. Here, we describe a very rare case of a 13-year old boy with cyclical cortisol hypersecretion secondary to corticotroph cell hyperplasia.

    Objective: To study the effects of angiotensin converting enzyme inhibitor (captopril) and angiotensin II antagonist receptor (valsartan) on neointima hyperplasia after vascular balloon injury. Methods: Thirty-six rabbit models were randomly divided into three groups: injuried group, captopril group and valsartan group. Captopril (2 mg·kg -1 ·d -1 po) and valsartan (10 mg·kg -1 ·d -1 po) were given to twelve rabbits respectively from 1 day before the right carotidarteries were injuried by 2.0 mm ballon cathether to 14 days after injury in captopil group and valsartan group. The medicine was not administered in the injuried group. The tissue plasminogen activator (tPA), plaminogen activor inhibitor-1 (PAI-1) antigen level and plasma endothelin (ET) levels were measured before injury, and 7, 14 days after vascular injury. The pathomorphoiogical examination were carried out 14 days after angioplasty. Results: The levels of plasma PAI-1 and ET in captopril group and valsartan group were significantly lower than those in the injuried group (P<0.05). The intimal thickness and extent of lumen stenosis in captopril and valsartan groups were significantly lower than those in the injuried group (P<0.05). Conclusion: Captopril and valsartan can inhibit neointima hyperplasia after vascular ballon injury. (authors)

    New York State law mandates specific intimate partner violence (IPV) documentation under all circumstances meeting the enumerated relationship and crime criteria at the scene of a domestic dispute. Law enforcement compliance with this mandate is unknown. We reviewed law enforcement completion rates of Domestic Violence Incident Reports (DVIRs) and assessed correlations with individual or legal factors. Law enforcement officers filed DVIRs in 54% of the cases (n = 191), more often when injury occurred (p < .01) and the defendant had prior court contact (p < .05). The discussion explores policy implications and potential means to rectify the gap between mandated processes and implementation. © The Author(s) 2015.

  11. Hypoxia-inducible factor-1 signalling promotes goblet cell hyperplasia in airway epithelium

    Goblet cell hyperplasia is a common feature of chronic obstructive pulmonary disease (COPD) airways, but the mechanisms that underlie this epithelial remodelling in COPD are not understood. Based on our previous finding of hypoxia-inducible factor-1α (HIF-1α) nuclear localization in large airways from patients with COPD, we investigated whether hypoxia-inducible signalling could influence the development of goblet cell hyperplasia. We evaluated large airway samples obtained from 18 lifelong non-smokers and 13 former smokers without COPD, and 45 former smokers with COPD. In these specimens, HIF-1α nuclear staining occurred almost exclusively in COPD patients in areas of airway remodelling. In COPD patients, 93.2 ± 3.9% (range 65 – 100%) of goblet cells were HIF-1α positive in areas of goblet cell hyperplasia, whereas nuclear HIF-1α was not detected in individuals without COPD or in normal-appearing pseudostratified epithelium from COPD patients. To determine the direct effects of hypoxia-inducible signalling on epithelial cell differentiation in vitro, human bronchial epithelial cells (HBECs) were grown in air-liquid interface cultures under hypoxia (1% O2) or following treatment with a selective HIF-1α stabilizer, (2R)-[(4-biphenylylsulphonyl)amino]-N-hydroxy-3-phenyl-propionamide (BiPS). HBECs grown in hypoxia or with BiPS treatment were characterized by HIF-1α activation, carbonic anhydrase IX expression, mucus-producing cell hyperplasia and increased expression of MUC5AC. Analysis of signal transduction pathways in cells with HIF-1α activation showed increased ERK1/2 phosphorylation without activation of epidermal growth factor receptor, Ras, PI3K-Akt or STAT6. These data indicate an important effect of hypoxia-inducible signalling on airway epithelial cell differentiation and identify a new potential target to limit mucus production in COPD. PMID:21557221

    Dopamine acting through D2 receptors (D2Rs) controls lactotroph proliferation and prolactin (PRL) levels. Ablation of this receptor in mice results in lactotroph hyperplasia and prolactinomas in aged females. Alternative splicing of the Drd2 gene generates 2 independent isoforms, a long (D2L) and a short (D2S) isoform, which are present in all D2R-expressing cells. Here, we addressed the role of D2L and D2S on lactotroph physiology through the generation and analysis of D2S-null mice and their comparison with D2L-null animals. These mice represent a valuable tool with which to investigate dopamine-dependent isoform-specific signaling in the pituitary gland. We sought to assess the existence of a more prominent role of D2L or D2S in controlling PRL expression and lactotroph hyperplasia. Importantly, we found that D2L and D2S are specifically linked to independent transduction pathways in the pituitary. D2L-mediated signaling inhibits the AKT/protein kinase B kinase activity whereas D2S, in contrast, is required for the activation of the ERK 1/2 pathway. Under normal conditions, presence of only 1 of the 2 D2R isoforms in vivo prevents hyperprolactinemia, formation of lactotroph's hyperplasia, and tumorigenesis that is observed when both isoforms are deleted as in D2R-/- mice. However, the protective function of the single D2R isoforms is overridden when single isoform-knockout mice are challenged by chronic estrogen treatments as they show increased PRL production and lactotroph hyperplasia. Our study indicates that signaling from each of the D2R isoforms is sufficient to maintain lactotroph homeostasis in physiologic conditions; however, signaling from both is necessary in conditions simulating pathologic states.

    In many cases, the oral health status indicates the general status of the body. 90% of the disorders of the body also manifest at the level of the oral cavity, which means that the dentist can draw the attention of a certain health problem. Diabetes mellitus is associated with a high prevalence of the lesions of the oral mucous, especially lichen planus, recurrent aphthous stomatitis or oral candidiasis. We present here a case of diabetes mellitus with hyperplasic lesion at the level of the inferior vestibule, extended to the right jugal mucosa. The lesion appeared pursuant to the application of removable prosthetics. The biopsy specimen was examined using normal and special staining (HE Hematoxiline - eosine, Van Gieson VG) and immunohistochemistry (IHC). In the HE stain, an epithelial hyperplasia was noticed as a result of the proliferation of the basal cells, associated with hyperkeratosis (parakeratosis or orthokeratosis). A moderated inflammatory limphoplasmocitary infiltrate, composed by lymphocytes and plasma cells, was present within the hyperplasic chorion. The immunohistochemical reactions revealed Ki-67 positive nuclei in the basal and suprabasal strata (indicating an increased proliferating activity); rare p53 positive nuclei in the basal stratum (indicating a suppressive action on the cell proliferation); CD3/CD8 positive cells in the inflammatory infiltrate (indicating an important number of T suppressor lymphocytes in the inflammatory infiltrate). In conclusion, diabetes mellitus is a disease which frequently determines major modifications at the level of the oral cavity. Interdisciplinary collaboration between the pathologist and the dentist is necessary for adequate diagnosis and successful treatment.

    2016-05-01

    Surgical debulking of the adenoma/transition zone has been the fundamental principle which underpins transurethral resection of the prostate - still acknowledged to be the gold-standard therapy for benign prostatic hyperplasia (BPH). However, there has been a recent resurgence in development of new BPH technologies driven by enhanced understanding of prostate pathophysiology, development of new ablative technologies, and the need for less morbid alternatives as the mean age and complexity of the treatment population continues to increase. The objective of this review is to highlight new BPH technologies and review their available clinical data with specific emphasis on unique features of the technology, procedural effectiveness and safety, and potential impact on current treatment paradigms. New technologies have emerged that alter the shape of the prostate to decrease urinary obstruction and enhance delivery of a lethal thermal dose by steam injection into the transition zone of the prostate. Energy can be delivered to the prostate via a beam of high-pressure saline or focused acoustic energy to mechanically disintegrate prostate tissue. Methods of cell death are being targeted with selectivity by the arterial supply with embolization and specific to prostate cells via injectable biological therapies. A number of new technologies are at various stages of development and improve on the transurethral resection of the prostate paradigm by moving closer to the ideal BPH therapy which is definitive, can be performed in minutes, in the office setting, with only local anesthesia and oral sedation.

    A 5-year-old male miniature dachshund was presented with a dermal nodule on the left forelimb that increased to 5 mm in diameter over a 2-month period. Grossly, the nodule was firm, and both the external and cut surfaces were homogeneously pale pink in colour. Microscopically, the nodule was comprised of mainly plump endothelial cells and inflammatory cells; among the latter, lymphocytes were predominant, with few scattered plasma cells, mast cells and macrophages. Lymphoid follicles with germinal centres were often observed. Mitotic figures were not observed amongst the endothelial cells. Immunohistochemically, the endothelial cells were positive for vimentin, factor VIII-related antigen and CD31, and the surrounding cells were positive for smooth muscle actin. Lymphocytes expressed CD3 or BLA36. These findings led to a diagnosis of cutaneous angiolymphoid hyperplasia. To the best of our knowledge, this is the first report of a cutaneous proliferative disorder comprising an admixture of proliferating vascular endothelial cells and lymphocytic infiltration with follicle formation in a dog.

  18. Classic congenital adrenal hyperplasia and puberty.

    2004-11-01

    Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders resulting from deficiency of one of the five enzymes required for synthesis of cortisol in the adrenal cortex. The most common form of the disease is classic 21-hydroxylase deficiency, which is characterized by decreased synthesis of glucocorticoids and often mineralocorticoids, adrenal hyperandrogenism and impaired development and function of the adrenal medulla. The clinical management of classic 21-hydroxylase deficiency is often suboptimal, and patients are at risk of developing in tandem iatrogenic hypercortisolism and/or hyperandogenism. Limitations of current medical therapy include the inability to control hyperandrogenism without employing supraphysiologic doses of glucocorticoid, hyperresponsiveness of the hypertrophied adrenal glands to adrenocorticotropic hormone (ACTH) and difficulty in suppressing ACTH secretion from the anterior pituitary. Puberty imposes increased difficulty in attaining adrenocortical suppression despite optimal substitution therapy and adherence to medical treatment. Alterations in the endocrine milieu at puberty may influence cortisol pharmacokinetics and, consequently, the handling of hydrocortisone used as replacement therapy. Recent studies have demonstrated a significant increase in cortisol clearance at puberty and a shorter half-life of free cortisol in pubertal females compared with males. Furthermore, children with classic CAH have elevated fasting serum insulin concentrations and insulin resistance. The latter may further enhance adrenal and/or ovarian androgen secretion, decrease the therapeutic efficacy of glucocorticoids and contribute to later development of the metabolic syndrome and its complications.

    A major hallmark of classical congenital adrenal hyperplasia (CAH) is genital ambiguity noted at birth in affected females, which leads to psychological and psychosexual issues in adult life. Attempts to correct genital ambiguity through surgical intervention have been partially successful. Fetal hyperandrogenemia and genital ambiguity have been shown to be preventable by prenatal administration of low-dose dexamethasone initiated before the 9th week of gestation. In 7 of 8 at-risk pregnancies, the unaffected fetus is unnecessarily exposed to dexamethasone for weeks until the diagnosis of classical CAH is ruled out by invasive procedures. This therapeutic dilemma calls for early prenatal diagnosis so that dexamethasone treatment can be directed to affected female fetuses only. We describe the utilization of cell-free fetal DNA in mothers carrying at-risk fetuses as early as 6 gestational weeks by targeted massively parallel sequencing of the genomic region including and flanking the CYP21A2 gene. Our highly personalized and innovative approach should permit the diagnosis of CAH before genital development begins, therefore restricting the purposeful administration of dexamethasone to mothers carrying affected females. © 2016 S.

    Full Text Available Objective. The most common form of congenital adrenal hyperplasia (CAH is 21-hydroxylase (21-OH deficiency due to mutation of the CYP21A2 gene. Patients with nonclassical CAH (NC-CAH are usually asymptomatic at birth and typically present in late childhood, adolescence, or adulthood with symptoms of excessive androgen secretion. Subfertility is relative in NC-CAH, but the incidence of spontaneous miscarriage is higher. Here, we report a previously undiagnosed female who gave birth to a normal male child and is planning to become pregnant again. Case Report. A 32-year-old female was referred to our clinic for obesity. Her medical history revealed that she had had three pregnancies. She was planning to become pregnant again. Her laboratory results revealed that she had NC-CAH. Since her husband is the son of her aunt and she had miscarriages and intrauterin exitus in her history, their genetic analyses were performed. Conclusion. Since most patients with NC-CAH have a severe mutation, these patients may give birth to a child with the classical CAH (C-CAH if their partner is also carrying a severe mutation. Females with NC-CAH who desire pregnancy must be aware of the risk of having an infant with C-CAH.

    Full Text Available Abstract Extra nodal marginal zone B-cell lymphoma (EMZL of the conjunctiva typically arises in the marginal zone of mucosa-associated lymphoid tissue. The pathogenesis of conjunctival EMZL remains unknown. We describe an unusual case of EMZL arising from reactive lymphoid hyperplasia (RLH of the conjunctiva. A 35-year-old woman had fleshy salmon-pink conjunctival tumors in both eyes, oculus uterque (OU. Specimens from conjunctival tumors in the right eye, oculus dexter (OD, revealed a collection of small lymphoid cells in the stroma. Immunohistochemically, immunoglobulin (Ig light chain restriction was not detected. In contrast, diffuse atypical lymphoid cell infiltration was noted in the left eye, oculus sinister (OS, and positive for CD20, a marker for B cells OS. The tumors were histologically diagnosed as RLH OD, and EMZL OS. PCR analysis detected IgH gene rearrangement in the joining region (JH region OU. After 11 months, a re-biopsy specimen demonstrated EMZL based on compatible pathological and genetic findings OD, arising from RLH. This case suggests that even if the diagnosis of the conjunctival lymphoproliferative lesions is histologically benign, confirmation of the B-cell clonality by checking IgH gene rearrangement should be useful to predict the incidence of malignancy.

    The intravascular papillary endothelial hyperplasia (IPEH/Masson's tumor) is a rare benign tumor of the skin and subcutaneous vessels. We report, in four pediatric cases, clinical presentation, care (diagnostic and surgical) of Masson's tumor in children. Two boys (two years) and two girls (four and six years) showed a pain subcutaneous tumor (one to five centimeters). They were in the transverse abdominal muscle, between two metatarsals, at the front of thigh and in the axilla. Imaging performed (MRI, Doppler ultrasound) evoked either a hematoma, a lymphangioma or hemangioma. The indication for removal was selected from pain and/or parental concern. The diagnosis was histologically. A lesion persisted in residual form (incomplete initial resection), and is currently not scalable for eleven years. This tumor is characterized by excessive proliferation and papillary endothelial cells in the vessels, following a thrombotic event. It is found mainly in adults (no specific age), and preferentially localizes in the face and limbs. The clinical differential diagnosis of this tumor is angiosarcoma. The imagery has not allowed in our series to diagnose but still essential to eliminate differential diagnoses. Only surgical excision with histological examination can differentiate. Our study emphasizes the possibility of pediatric cases with two cases of unusual locations (abdominal and axilla). Clinical presentations we met, now lead us to direct our histologist looking for a Masson tumor in any child with a subcutaneous tumor and/or intramuscular pain, sudden onset, and vascular appearance (after excluding an arteriovenous malformation).

  3. Growth and development in children with classic congenital adrenal hyperplasia.

    2017-02-01

    Final height outcome in classic congenital adrenal hyperplasia (CAH) has been of interest for many years. With analysis of growth patterns and used glucocorticoid regimens, enhanced treatment strategies have been developed and are still under development. Most of the current reports on final height outcome are confirmative of previous results. Final height data is still reported in cohorts that were diagnosed clinically and not by newborn screening. Clinical diagnosis of CAH leads to delayed diagnosis especially of simple virilizing CAH with significantly advanced bone age resulting in early pubertal development and reduced final height. In contrast salt-wasting CAH is diagnosed at an earlier stage in most cases resulting in better final height outcome in some cohorts. Nevertheless, final height outcome in patients with CAH treated with glucocorticoids is lower than the population norm and also at the lower end of genetic potential. Achievement of regular adult height is still a challenge with conventional glucocorticoid treatment in patients with CAH, which is why new hydrocortisone formulations and new treatment options for CAH are underway.

    There have been several publications on population or community prevalence of benign prostatic hyperplasia and prostate cancer from various countries and races but few reports are from Africa on Africans. A review on the prevalence of benign prostatic hyperplasia and prostate cancer in Africans and other races. The current literature on prevalence of benign prostatic hyperplasia (BPH), prostate cancer (PC), and benign prostatic hyperplasia co-existing with prostate cancer in Africans and other races is reviewed. Benign prostatic hyperplasia (BPH) prevalence in Ghana is responsible for 60% acute retention of urine and 28.6% of haematuria. Worldwide prevalence of BPH varies from 20 - 62% in men over 50 years and this includes USA, UK, Japan and Ghana. Reports from South Africa indicate prevalence of over 50% in adult males of 60 years. BPH co-existing with PC - Reports from USA, UK and Japan and Ghana reveal moderate association of BPH and PC. The co-existence of PC in patients being treated for BPH is 3 - 20% Prostate Cancer prevalence - There is high prevalence in USA, Scandinavian Countries, African Americans (AA) and Caribbean blacks. Ghana, Trinidad & Tobago have reported high prevalence of 6 -10% in men aged 50 years and above but others reported low prevalence in Africans from Africa. The low reporting from Africa of 10 - 40:100,000 is attributable to under reporting, absence of PSA screening/testing, lack of reliable cancer registries and poor medical facilities. Economic Costs of BPH and PC: BPH in the USA national direct costs are estimated at U$4Billion and individual costs of US$1536 annually. In Ghana, individual costs for BPH medications range from US$300 - 550 per year and cost for simple prostatectomy/TURP is estimated at US$1100. For prostate cancer, individual direct costs from Europe range from 6,575 - 12,000 euros, £2818.00 UK and over U$12,000 - 20,000 in USA per annum. In Ghana, individual direct costs ranges, for radical prostatectomy and

    Exophytic oral verrucous hyperplasia (OVH) is a new entity described by an expert working group from South Asia. First reported in Taiwan, there are no reports so far from an Indian population. The aim was to use the microscopic features described by the expert group to differentiate OVH from other oral verruco-papillary lesions in an Indian archive. In a retrospective multicentre study, using pathology archives, 188 verruco-papillary lesions were retrieved from pathology archives. A proforma listing histopathological criteria for OVH based on published guidelines (Annals of Dentistry, University of Malaya, 2013) was used. Patients' demographic and clinical data were transcribed from patient charts. The Pearson chi-square test was used to determine associations between clinical and histopathological features. Of 188 oral verruco-papillary lesions that were evaluated, based on microscopic features the cases were reclassified as OVH (57), verrucous carcinoma (VC) (84), oral squamous cell carcinoma (16), and other verruco-papillary lesions (31). Both OVH (70%) and VC (60%) showed male predominance and commonly affected buccal mucosa (OVH 74% and VC 57%). Absence of downward growth of the hyperplastic epithelium into lamina propria when compared with the level of the basement membrane of the adjacent normal epithelium was a distinct feature in OVH. Keratin plugging, epithelial dysplasia and subepithelial lymphocytic infiltration were found to be significantly different (P < 0.05) in OVH versus VC. The sample size of other verruco-papillary lesions was insufficient for statistical comparison. Apart from the absence of an endophytic growth pattern in OVH, we noted the presence of dysplasia in OVH. This significant observation does institute a debate as to whether this enigmatic lesion could possibly be a precedent of oral squamous or verrucous carcinoma. We propose OVH is a distinct entity in our Indian population and should be considered in the classification of oral

    Full Text Available Purpose: To investigate the chromosomal changes in patients with benign prostatic hyperplasia (BPH. Materials and Methods: A total of 54 patients diagnosed with clinical BPH underwent transurethral prostate resection to address their primary urological problem. All patients were evaluated by use of a comprehensive medical history and rectal digital examination. The preoperative evaluation also included serum prostate-specific antigen (PSA measurement and ultrasonographic measurement of prostate volume. Prostate cancer was detected in one patient, who was then excluded from the study. We performed conventional cytogenetic analyses of short-term cultures of 53 peripheral blood samples obtained from the BPH patients. Results: The mean (±standard deviation age of the 53 patients was 67.8±9.4 years. The mean PSA value of the patients was 5.8±7.0 ng/mL. The mean prostate volume was 53.6±22.9 mL. Chromosomal abnormalities were noted in 5 of the 53 cases (9.4%. Loss of the Y chromosome was the most frequent chromosomal abnormality and was observed in three patients (5.7%. There was no statistically significant relationship among age, PSA, prostate volume, and chromosomal changes. Conclusions: Loss of the Y chromosome was the main chromosomal abnormality found in our study. However, this coexistence did not reach a significant level. Our study concluded that loss of the Y chromosome cannot be considered relevant for the diagnosis of BPH as it is for prostate cancer. Because BPH usually occurs in aging men, loss of the Y chromosome in BPH patients may instead be related to the aging process.

    Objective: This study aims to observe the effect and mechanism of Xiaoru Sanjie Jiaonang (XRSJ) on the treatment of mammary gland hyperplasia, and provide a theoretical basis and clinical evidence for clinical expansion. Methods: Japanese white rabbits were randomly divided into three groups: high-, middle- and low-dose groups; Xiaoyao Pill group; model control group; normal control group. The observation points were as follows: before XRSJ administration, three months after XRSJ administration, and three months after XRSJ discontinuance. Changes in breast height, morphological changes of the mammary gland under a light and electron microscope, and the expression of ki-67 were observed. At the same time, patients diagnosed with mammary gland hyperplasia at an Outpatient Clinic were selected and divided into treatment groups. These patients received XRSJ and Xiaoyao Pills, respectively, for one month, while patients in the control group did not receive any drug treatment. Clinical efficacy was observed while rechecking at the Outpatient Clinic after three months. Treatment with a therapeutic dose of XRSJ could significantly reduce breast height, decrease the number of lobules and acini in hyperplastic mammary glands and the layer number of ductal glandular epithelial cells, substantially lower the content of serum estradiol (E2), significantly downregulate the expression of ki-67 protein in mammary tissues, and inhibit mammary gland hyperplasia. Conclusion: XRSJ treatment can relieve mammary tissue hyperplastic lesions, reduce E2 levels and downregulate the expression of ki-67. It has a significant therapeutic effect on mammary gland hyperplasia. PMID:29636873

    Objective: To evaluate the CT findings of lymphofollicular thymic hyperplasia in adult myasthenia gravis (MG). Methods: The CT findings of thymus area of 134 adult patients with lymphofollicular thymic hyperplasia in MG were reviewed, all of them with surgically and histologically proven diagnosis, and compared with the CT findings of 165 normal subjects. Results: In the group of patient, CT showed enlargement of thymus in 31 patients, 5 patients had nodule or mass ( 3 cm) and 9 patients (6.7%) had normal size thymus with soft-tissue density, it can considered with thymic hyperplasia. The spotty or streak shadow showed in other patients, though it could not be certain diagnosed as thymic hyperplasia, but could not be except it. The thymus area tissue complete replacement by fatty density were not found in patient group. The CT findings of patients had marked difference when compared with group of normal subjects (P<0.01), except the spotty or streak shadows. Conclusion: CT scan is an important method in diagnosing thymic lymphofollicular hyperplasia of MG in adult. (authors)

    This study was designed to investigate the efficacy of cilostazol on the prevention of in-stent neointimal hyperplasia as measured by both quantitative coronary angiography (CAG) and volumetric intravascular ultrasound (IVUS). Fifty-nine patients (39 men, age 62 years) undergoing elective coronary stenting were randomly assigned to receive aspirin plus clopidogrel or ticlopidine (Group I, n=28, 30 lesions) or aspirin plus clopidogrel or ticlopidine plus cilostazol (Group II, n=31, 35 lesions). CAG and IVUS were performed and repeated at 6 months to assess the primary endpoints of minimal luminal diameter (MLD) and in-stent neointimal hyperplasia volume. Follow-up CAG was performed on all patients and follow-up IVUS study was available for 50 lesions in 48 patients (24 lesions in Group I, 26 in Group II). There were no significant differences in the baseline angiographic data between the 2 groups. At 6 months follow-up, in-stent MLD was 1.90±0.76 mm in Group I and 2.41±0.85 mm in Group II (p=0.006). Volumetric IVUS at 6 months demonstrated that in-stent intimal hyperplasia volume per stent length was 2.2±1.4 mm 3 /mm in Group I and 1.0±0.5 mm 3 /mm in Group II (p=0.001). Triple antiplatelet therapy including cilostazol seems to be more effective at preventing in-stent neointimal hyperplasia than a dual antiplatelet regimen. (author)

  18. Hyperplasia of elastic tissue in hepatic schistosomal fibrosis

    Directory of Open Access Journals (Sweden)

    Zilton A. Andrade

    1991-12-01

    Full Text Available Elastic tissue hyperplasia, revealed by means of histological, immunocytochemical and ultrastructural methods, appeared as a prominent change in surgical liver biopsies taken from 61 patients with schistosomal periportal and septal fibrosis. Such hyperplasia was absent in ecperimental murine schistosomiasis, including mice with "pipe-stem" fibrosis. Displaced connective tissue cells in periportal areas, such as smooth muscle cells, more frequently observed in human material, could be the site of excessive elastin synthesis, and could explain the differences observed in human and experimental materials. Elastic tissue, sometimes represented by its microfibrillar components, also appeared to be more condensed in areas of matrix (collagen degradation, suggesting a participation of this tissue in the remodelling of the extracellular matrix. By its rectratile properties elastic tissue hyperplasia in hepatic schistosomiasis can cause vascular narrowing and thus play a role in the pathogenesis of portal hypeertension.

    2009-05-01

    Full Text Available The aim of this study was to examine the prevalence and clinicopathological significance of KRAS point mutation in endometrial hyperplasia and carcinoma. We analysed KRAS in 11 cases of complex atypical hyperplasia and in 49 endometrial carcinomas using polymerase chain reaction associated with restriction fragment length polymorphism (PCR-RFPL. Point mutations at codon 12 of KRAS oncogene were identified in 7 of 49 (14,3% tumor specimens and in 2 of 11 (18,2% hyperplasias. No correlation was found between KRAS gene mutation and age at onset, histology, grade of differentiation and clinical stage. We conclude that KRAS mutation is a relatively common event in endometrial carcinogenesis, but with no prognostic value.

    2009-11-01

    This study of a predominantly Hispanic sample of 92 male and 140 female college students examines both gender symmetry in intimate partner violence (IPV) and inconsistent relationships found in previous studies between sexist attitudes and IPV. Results indicate that although comparable numbers of men and women perpetrate and are victimized in their relationships with intimate partners, the path models suggest that women's violence tends to be in reaction to male violence, whereas men tend to initiate violence and then their partners respond with violence. Benevolent sexism was shown to have a protective effect against men's violence toward partners. Findings highlight the importance of studying women's violence not only in the context of men's violence but also within a broader sociocultural context.

    2017-03-01

    Barry Marshall and Robin Warren were the first to show that the chronic diseases (gastric ulcer and chronic gastritis) were caused by an infection (Helicobacter pylori). The chronic disease benign prostatic hyperplasia belongs to the same ilk, except that the infection process is much more subtle and complex. The enzyme Phospholipase D (PLD) which is attached to the outer membrane of Escherichia coli (E. coli) has now been almost completely proven to be the basic cause of BPH. The evidence for this process is now extremely strong and compelling. PLD obtained from the organism Streptomyces chromofuscus has been used in past research because of its PLD content. It is commercially available. In vitro, on a culture of prostatic smooth muscle, PLD stimulated the production of lysophosphatidic acid (LPA) which acted on and caused substantial growth of that muscle in accordance with the quantity of PLD/ LPA generated. It has been asserted that repeated colonization by E. coli of the transitional zone of the prostate gland and the release of PLD following repeated destruction of these colonized bacteria, is the basic cause of BPH. The evidence for colonizing and re-colonizing infection is now overwhelming. PLD is a simple lipid consisting of a phosphate, glycerol and a fatty acid. After absorption into the prostatic stroma (which consists of connective tissue and of smooth muscle), it stimulates the production of LPA which, in turn, apart from directly stimulating prostatic smooth muscle, also acts on the connective tissue in the prostate and induces a complex mixture of growth regulatory proteins, which include members of the fibroblast, insulin-like and growth transforming factor families and implicates autocrine hormones acting on the stroma and paracrine hormones acting on epithelium. Also involved, are a variety of interleukins and other inflammatory cell cytokines, secreted by the stroma, which may further promote autocrine/paracrine proliferation of BPH cells

    2014-01-01

    Full Text Available This theoretical study reviews two of the most cited profiles of intimate partner batterers in the scientific literature, paying special attention to the most notable differences between them, as well as to their common criteria. The study also discusses one of the longest standing controversies in various research studies, including the particular overview with respect to Spain: it being the constant yet erroneous reference to the equivalence of psychopathy and antisocial personality disorder. Similarly, special attention is paid to the implications of considering intimate partner batterers as having either a psychopathological or psychopathic profile, while also stressing the specific role played by psychopathy in the intimate partner batterer and, concerning psychopathic intimate partner batterers, such aspects as their specific motives for perpetrating intimate partner violence and the evaluation instruments of this particular profile. Finally, a series of future directives for research concerning psychopathic intimate partner batterers are also pointed out.

The fit of findings with compensatory, spillover, and compartmentalization hypotheses was explored. Participants were 49 mothers and 51 children younger than 3 years of age affected by IPV. Data were collected on maternal-child interactions, child development, social support, difficult life circumstances, family functioning, child temperament, and parental depression. The findings suggested developmental impacts on children in the sample, along with children's high sensitivity and responsiveness to their caregivers. Although some spillover effects were observed, the predominant observation was of mothers and infants compensating for exposure to IPV in their interactions.

    Full Text Available Background/Aim. Benign prostatic hyperplasia (BHP is one of the most common diseases of elderly men. The aim of this study was to evaluate the effect of surgical treatment of benign prostatic hyperplasia to voiding and urinary bladder filling symptoms. Quantification of voiding and filling symptoms was done with the International Prostate Symptom Score (IPSS. Method. The study included 80 patients with BHP, of whom 40 were treated with open prostatectomy (group A, and other 40 with transurethral resection of prostate gland (group B. All the patients were under 80 years old (average age in the group A was 70.23 years with a variation interval of 21 years, and in the group B 69.37 years with a variation interval of 22 years, with a value of IPSS > 19 points, quantity of residual urine higher than 150 mL, the weight of benign prostatic gland hyperplasia tissue over 30 grams for the method of prostate transurethral resection, and over 80 grams for the method of open prostatectomy. To all patients, for two times, the value of IPSS was determined, and then in a postoperative period in time intervals of 4 and 12 weeks. Results. Arithmetic mean of IPSS preoperatively was 32.05 points in the group A and 31.75 points in the group B. During the postoperative check-ups in time intervals of 4 and 12 weeks, arithmetic means of IPSS in the group A were 5.4 and 1.85 points, respectively, and in the group B 11.425 and 9.025 points, respectively. Surgical treatment had better effect on voiding symptoms than on urinary bladder filling ones. Conclusion. After the mentioned surgical procedures a significant reduction of the lower urinary tract symptoms quantified by the IPSS was observed. Surgical treatment of BHP had a more pronounced effect on the voiding symptoms in relation to filling ones.

    Research in intimate partner violence has focused on married, cohabiting, adolescents, or college aged women. The experience of intimate partner violence by single women has not been studied separately from other groups of women. An interpretive phenomenological approach was used with feminist inquiry to gain insight into the experience of intimate partner violence by single women. The overarching theme was control and manipulation by the abuser. Subthemes included not feeling safe, poor communication skills, and caretaking. Nurses need to be aware of the occurrence of intimate partner violence in male and female partnered relationships to provide comprehensive and nonjudgmental care.

    Intimate partner violence is a significant public health problem in our society, affecting women disproportionately. Intimate partner violence takes many forms, including physical violence, sexual violence, stalking, and psychological aggression. While the scope of intimate partner violence is not fully documented, nearly 40% of women in the United States are victims of sexual violence in their lifetimes and 20% are victims of physical intimate partner violence. Other forms of intimate partner violence are likely particularly underreported. Intimate partner violence has a substantial impact on a woman's physical and mental health. Physical disorders include the direct consequences of injuries sustained after physical violence, such as fractures, lacerations and head trauma, sexually transmitted infections and unintended pregnancies as a consequence of sexual violence, and various pain disorders. Mental health impacts include an increased risk of depression, anxiety, posttraumatic stress disorder, and suicide. These adverse health effects are amplified in pregnancy, with an increased risk of pregnancy outcomes such as preterm birth, low birthweight, and small for gestational age. In many US localities, suicide and homicide are leading causes of pregnancy-associated mortality. We herein review the issues noted previously in greater depth and introduce the basic principles of intimate partner violence prevention. We separately address current recommendations for intimate partner violence screening and the evidence surrounding effectiveness of intimate partner violence interventions.

    The simplistically and ambiguously termed 'fibrostenosis' of bowel is a hallmark of severe Crohn's disease [CD] and a major contributor to medical treatment failure. Non-invasive imaging assessment and novel medical therapy targeting this condition are under investigation, which particularly requires a better understanding of the underlying histological basis. We analysed 48 patients with stricturing Crohn's ileitis or/and colitis that required surgical resection. The most representative sections of the fibrostenotic, non-stenotic and uninvolved regions were reviewed for histological analysis. For each layer of bowel wall (mucosa including muscularis mucosae [MU], submucosa [SM], muscularis propria [MP], subserosal adventitia [SS]), histological abnormalities were evaluated individually, including active and chronic inflammation, fibrosis, smooth muscle hyperplasia or hypertrophy, neuronal hypertrophy and adipocyte proliferation. A novel semiquantitative histological grading scheme was created. The most significant histopathological features characterizing the stricturing intestines were smooth muscle hyperplasia of SM, hypertrophy of MP and chronic inflammation. The muscular alteration was predominant in all layers. The overall muscular hyperplasia/hypertrophy was positively correlated with chronic inflammation and negatively correlated with fibrosis, whereas SM muscular hyperplasia was also associated with MU active inflammation. Similar changes, to a lesser extent, occurred in the adjacent non-stenotic inflamed bowel as well. In CD-associated 'fibrostenosis', it is the smooth muscle hyperplasia/hypertrophy that contributes most to the stricturing phenotype, whereas fibrosis is less significant. The 'inflammation-smooth muscle hyperplasia axis' may be the most important in the pathogenesis of Crohn's strictures. Copyright © 2016 European Crohn’s and Colitis Organisation (ECCO).

    Full Text Available Fouad Aoun1, Quentin Marcelis,1,2 Thierry Roumeguère,2 1Department of Urology, Jules Bordet Institute, 2Department of Urology, Erasme Hospital, University Clinics of Brussels, Université Libre de Bruxelles, Brussels, Belgium Abstract: Benign prostatic hyperplasia (BPH represents a spectrum of related lower urinary tract symptoms (LUTS. The cost of currently recommended medications and the discontinuation rate due to side effects are significant drawbacks limiting their long-term use in clinical practice. Interventional procedures, considered as the definitive treatment for BPH, carry a significant risk of treatment-related complications in frail patients. These issues have contributed to the emergence of new approaches as alternative options to standard therapies. This paper reviews the recent literature regarding the experimental treatments under investigation and presents the currently available experimental devices and techniques used under local anesthesia for the treatment of LUTS/BPH in the vast majority of cases. Devices for delivery of thermal treatment (microwaves, radiofrequency, high-intensity focused ultrasound, and the Rezum system, mechanical devices (prostatic stent and urethral lift, fractionation of prostatic tissue (histotripsy and aquablation, prostate artery embolization, and intraprostatic drugs are discussed. Evidence for the safety, tolerability, and efficacy of these “minimally invasive procedures” is analyzed.

    Full Text Available Abstract Background Mammary sclerosing lobular hyperplasia is an uncommon benign lesion of adolescent and young women. Fine-needle aspiration cytology of mammary sclerosing lobular hyperplasia is said to show characteristic features that include an absence of stromal fragments. Case presentation In this article, we describe a case of sclerosing lobular hyperplasia that occurred in the right breast of a 12-year-old girl. Fine-needle aspiration cytology showed some fibroadenoma-like features including the presence of stromal fragments, while branched tubular fragments were not seen. The diagnosis of sclerosing lobular hyperplasia was made on histologic examination that showed preserved acinar architecture with lobular hyperplasia and sclerosis of intralobular and interlobular stroma. Conclusion Fine-needle aspiration cytology features of mammary sclerosing lobular hyperplasia are not diagnostic and overlap with those of fibroadenoma; however, a distinction between the two benign entities is of no clinical significance. The definitive diagnosis of sclerosing lobular hyperplasia requires histopathologic evaluation.

    Full Text Available INTRODUCTION: The treatment of benign prostate hyperplasia (BPH presents 2 options: medical or surgical, and there are doubts about what is the best treatment since 80% of patients who undergo surgery become asymptomatic and 10 to 40% of those under medical regimen undergo surgery within a 5 years period. It is difficult to assess the actual costs of treating BPH in Brazil due to several factors, among them regional particularities and the scarcity of current statistical data. PATIENTS AND METHODS: Recently, in the Ribeirão Preto area, São Paulo, Brazil, the IPSS (International Prostatic Symptoms Score and quality of life were verified in 934 volunteers. It was determined the percentage of individuals with ages ranging from 40 to 79 years with moderate symptoms (score 8-19 and with severe symptoms (score 20-35, values for which are indicated medical and surgical treatment, respectively, according to the Brazilian Society of Urology consensus on BPH. Data on Brazilian population in that age range were obtained from the Brazilian Institute of Geography and Statistics referent to the year of 2000. It was determined the number of patients, according to the criteria above, subjected to either one of the treatments mentioned. Surgical costs of prostate transurethral resection were researched according to Unified Health System - SUS tables (US$ 173 and of Brazilian Medical Society - AMB with a mean cost in 3 hospitals of US$ 933. Drug costs were calculated by the annual mean price (US$ 355 of 4 alpha-blockers (tamsulosin, alfuzosin, doxazosin and terazosin. RESULTS: The estimated population for medical treatment was 5,397,321 individuals, with a cost corresponding to US$ 1,916,489,055.00. The estimated population for surgical treatment was 2,040,299 men, what would represent a cost of US$ 353,291,204.00 based on the SUS table and of US$ 1,904,279,066.00 based on AMB with hospital expenses included. CONCLUSION: All theses facts induce us to predict

  9. Classificatory multiplicity: intimate partner violence diagnosis in emergency department consultations.

    To explore the naming, or classification, of physical assaults by a partner as 'intimate partner violence' during emergency department consultations. Research continues to evidence instances when intimate partner physical violence is 'missed' or unacknowledged during emergency department consultations. Theoretically, this research was approached through complexity theory and the sociology of diagnosis. Research design was an applied, descriptive and explanatory, multiple-method approach that combined qualitative semistructured interviews with service-users (n = 8) and emergency department practitioners (n = 9), and qualitative and quantitative document analysis of emergency department health records (n = 28). This study found that multiple classifications of intimate partner violence were mobilised during emergency department consultations and that these different versions of intimate partner violence held different diagnostic categories, processes and consequences. The construction of different versions of intimate partner violence in emergency department consultations could explain variance in people's experiences and outcomes of consultations. The research found that the classificatory threshold for 'intimate partner violence' was too high. Strengthening systems of diagnosis (identification and intervention) so that all incidents of partner violence are named as 'intimate partner violence' would reduce the incidence of missed cases and afford earlier specialist intervention to reduce violence and limit its harms. This research found that identification of and response to intimate partner violence, even in contexts of severe physical violence, was contingent. By lowering the classificatory threshold so that all incidents of partner violence are named as 'intimate partner violence', practitioners could make a significant contribution to reducing missed intimate partner violence during consultations and improving health outcomes for this population.

    Describe gender-based violence by intimate partners against female nurses in a sample of nurses in Andalucia, Spain. Descriptive transversal study. Hospitals and primary health care districts in Andalucia. Six hundred and twenty-two female nurses that work as nurses in the eight provinces in Andalucia (Spain). Social-demographic characteristics and presence of abuse (psychological, physical and sexual). 78.5% of the nurses were married or with a regular partner and had the economic income based on both salaries; 71.1% had a child or an elderly dependent person. It was proved that there can be a statistical association between abuse and: marital status; life together; familiar economic support and children and/or dependent elderly person. The average age was 42.5±8.1 years old (22-62 years) and presented statistical age differences comparing both groups: abused (average 44 years) and non-abused (average 41.8 years). Between the married couples studied, 21.7% of them belong to the social class I and 16.9% to the social class II. Between all studied nurses, 33.0% suffered abuse, among which 75.1% were psychologically abused. Of all the abuse cases 60% were less severe and 40% more serious. It was confirmed the presence of intimate partner violence (IPV) against nurses, which was predominantly psychological abuse, but others classes of abuse were present too.

    Full Text Available Previous research indicates that persons who self-report a high level of preoccupation with celebrities tend to have lower levels of well-being. We administered the “Romantic Partner Conflict Scale”, the “Love Attitudes Scale”, the soulmate subscale from the “Relationship Theories Questionnaire”, and the anxiety subscale from the “Experiences in Close Relationships Scale” to 330 students from four universities to see how well scores on these measures would predict scores on each of the three subscales from the “Celebrity Attitude Scale” (CAS. We predicted that persons whose scores on these measures of intimate relationships indicated a troubled, anxious, or poor quality relationship would have higher scores on the CAS, especially on its two problematic subscales. In three multiple regressions, specific measures of behavior during conflict with a romantic partner and certain love styles significantly predicted scores on all three of the CAS subscales. We discuss the implications of being a celebrity worshiper on one’s relationship with an intimate partner.

    Several studies have implicated estrogen and the estrogen receptor (ER) in the pathogenesis of benign prostatic hyperplasia (BPH); however, the mechanism underlying this effect remains elusive. In the present study, we demonstrated that estrogen (17β-estradiol, or E2)-induced activation of the G protein-coupled receptor 30 (GPR30) triggered Ca 2+ release from the endoplasmic reticulum, increased the mitochondrial Ca 2+ concentration, and thus induced prostate epithelial cell (PEC) apoptosis. Both E2 and the GPR30-specific agonist G1 induced a transient intracellular Ca 2+ release in PECs via the phospholipase C (PLC)-inositol 1, 4, 5-triphosphate (IP 3 ) pathway, and this was abolished by treatment with the GPR30 antagonist G15. The release of cytochrome c and activation of caspase-3 in response to GPR30 activation were observed. Data generated from the analysis of animal models and human clinical samples indicate that treatment with the GPR30 agonist relieves testosterone propionate (TP)-induced prostatic epithelial hyperplasia, and that the abundance of GPR30 is negatively associated with prostate volume. On the basis of these results, we propose a novel regulatory mechanism whereby estrogen induces the apoptosis of PECs via GPR30 activation. Inhibition of this activation is predicted to lead to abnormal PEC accumulation, and to thereby contribute to BPH pathogenesis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Directory of Open Access Journals (Sweden)

    Kazandjieva Jana

    2016-03-01

    Full Text Available Congenital generalized hypertrichosis, in its most common form, is idiopathic. In the absence of underlying endocrine or metabolic disorders, congenital generalized hypertrichosis is rare in humans, affecting as few as one in a billion individuals and may be an isolated condition of the skin, or a component feature of other disorders or syndromes. Congenital generalized hypertrichosis terminalis is an extremely rare condition, a distinct subset of disorders with congenital hypertrichosis, presenting with excessive hair as the primary clinical feature. Congenital generalized hypertrichosis terminalis is characterized by universal excessive growth of pigmented terminal hair and often accompanied with gingival hyperplasia and/or a coarse face. Gingival hyperplasia may be delayed even until puberty. Its pathogenesis may be caused by one of the following mechanisms: conversion of vellus to terminal hairs and/or prolonged anagenetic stage, and/or increase in the number of hair follicles. Since the Middle Ages, less than 60 individuals with congenital hypertrichosis terminalis have been described, and, according to the most recent estimates, less than 40 cases were documented adequately and definitively in the literature. Recent articles identified congenital generalized hypertrichosis terminalis as a genomic disorder.

    Stromal-epithelial interaction plays a pivotal role to mediate the normal prostate growth, the pathogenesis of benign prostatic hyperplasia (BPH), and prostate cancer development. Until now, the stromal androgen receptor (AR) functions in the BPH development, and the underlying mechanisms remain largely unknown. Here we used a genetic knockout approach to ablate stromal fibromuscular (fibroblasts and smooth muscle cells) AR in a probasin promoter-driven prolactin transgenic mouse model (Pb-PRL tg mice) that could spontaneously develop prostate hyperplasia to partially mimic human BPH development. We found Pb-PRL tg mice lacking stromal fibromuscular AR developed smaller prostates, with more marked changes in the dorsolateral prostate lobes with less proliferation index. Mechanistically, prolactin mediated hyperplastic prostate growth involved epithelial-stromal interaction through epithelial prolactin/prolactin receptor signals to regulate granulocyte macrophage-colony stimulating factor expression to facilitate stromal cell growth via sustaining signal transducer and activator of transcription-3 activity. Importantly, the stromal fibromuscular AR could modulate such epithelial-stromal interacting signals. Targeting stromal fibromuscular AR with the AR degradation enhancer, ASC-J9®, led to the reduction of prostate size, which could be used in future therapy. PMID:23893956

    Intimate partner violence is one of the most pervasive global public health problems affecting women. It results in untold costs to the healthcare system and is positively linked to eight out of ten leading indicators for Healthy People 2010. Intimate partner violence also is one of the factors associated with adverse childhood experiences that result in negative healthcare behaviours. Intimate partner violence has been the subject of film, made for television movies and music videos. The use of film as an innovative tool to teach about common health and mental health disorders is well-documented. Film also has been used as an adjunctive therapeutic tool in counselling. This paper will provide an overview of intimate partner violence, its portrayal in popular film and ways in which educators may use film to teach intimate partner violence-related topics.

  1. Homicides between heterosexual intimates: Criminological and victimological characteristics

    Simeunović-Patić Biljana J.

    2002-01-01

    Full Text Available In this paper the problem of homicidal violence between heterosexual intimates is analyzed, and the need for its treatment as a specific criminological issue denoted, having in mind many of its distinctive etiological and victimological dimensions. The presented findings of an empirical research on intimate homicides committed in Belgrade from 1985 to 1993 allowed for a testing of some hypotheses related to the factors of homicidal criminalization and victimization within the context of the intimate heterosexual relationships. The evidence on history and dynamics of deeply disturbed intimate relations, as well as some typical characteristics of male intimate partners in violent heterosexual relationships, are particularly considered. On the bases of research findings, it seems possible that the plausible preventive strategies can be developed.

    Focal epithelial hyperplasia or Heck's disease is an infrequent asymptomatic condition caused by human papillomavirus types 13 or 32 affecting the mucous membrane of the mouth and is commonly seen in young individuals. Firstly, it was described in Indians and Eskimos, but it exists in various populations. We present three cases of Heck's disease in an Afghan immigrant family group living in Iran that seem to have familial predominance. The disease was identified as oral focal epithelial hyperplasia on the basis of histopathologic and clinical findings. The lesions were reduced significantly after 4 months of good oral hygiene. Dentists should be familiar with the clinical manifestations of these types of lesions that affect the oral cavity. In fact, histopathologic assessment and clinical observation are necessary to establish the diagnosis.

    Atypical epithelial hyperplasia (AEH) of the breast is considered benign histological lesions with breast cancer risk. This review focuses on clinical signification and management of AEH that remains controversial. A review of published studies was performed using medline database. In this review, we fully describe the current evidence available. In particular, we describe 1) data from immunohistochemistry and molecular studies that suggest AEH is a precursor of breast cancer; 2) epidemiological studies demonstrate low rate of breast cancer in women with AEH; 3) surgical excision is necessary after diagnosis of AEH, such as lobular carcinoma in situ or atypical ductal hyperplasia, on core needle biopsy; 4) although current recommendations are evolving to fewer (if not no) excisions for flat epithelial with atypia and classic lobular neoplasia found on percutaneous biopsy (without radiologic indications for excision). Expert commentary: HEA management steel need prospective evidences, but recent retrospective data give some clue for less invasive management for some of HEA.

    Multifocal epithelial hyperplasia (MEH), also known as focal epithelial hyperplasia and Heck disease, is a relatively rare condition caused by the human papillomavirus. This case report describes a 92-year-old man who presented with multiple, asymptomatic, circumscribed, soft, flattened papules in different sizes on the retrocommissure of his lower lip. The lesions were of 2 months' duration and had the same coloration as the adjacent normal mucosa. Histopathologic examination showed orthokeratinized stratified squamous epithelium with acanthosis, some areas of club-shaped rete ridges, and a few superficial epithelial cells with koilocytic changes and a mitosoid-like appearance. A diagnosis of MEH was established. Although MEH tends to occur in the first 2 decades of life, it can be encountered in elderly patients as well.

    To evaluate the ultrasonographic appearance of fibroadenomatoid hyperplasia of the breast. We retrospectively reviewed US findings including size, shape, border, boundary echo, internal echo, posterior echo, lateral echo, and transverse/anteroposterior diameter of 19 patients (mean age 36.6 years) with pathologically proven fibrodenomatoid hyperplasia. Mammogramas were available in 18 patients. On US size, shape, border, internal echo, boundary echo, posterior echo, lateral echo, the ratio of transverse to anteroposterior diameter were analyzed by two radiologist in agreement. Fifteen of 19 patients presented with palpable masses. On US, the mean size of the masses was 13 mm (range, 4-26 mm). The shape of lesions were round to oval in 10 cases (53%), lobulated in 6 cases (32%), irregular in 3 cases (15%). The borders of the lesions were sharp-well defined in 11 cases (58%), unsharp-ill defined in 8 cases (42%). Fourteen cases(74%) showed fine homogeneous internal echo and 5 cases (26%) showed coarse heterogeneous internal echo. Nonexistent or regular fine boundary echo was shown in 11 cases (58%) and irregular thick boundary echo was shown in 8 cases (42%).Posterior sonic enhancement was shown in 10 cases (53%), posterior sonic shadowing in 6 cases (32%). And three cases (15%) showed no posterior echo. Marked lateral echo was demonstrated in 11 cases (58%). The transverse/anteroposterior diameter ratio ranged between 1.0 and 1.5 in 1 case (5.5%), below 1.0 in 1 case (5.5%), and above 1.5 and 17 cases (89%). Mammogram showed no abnormality in ten patients with dense breast, mass like density in seven patients, and clustered microcalcification in one patient. Fibroadenomatoid hyperplasia was usually presented in fourth decade as a palpable breast mass and common US findings were similar to fibroadenoma. However, histopathologic confirmation was needed for the diagnosis because fibroadenomatoid hyperplasia sometimes showed the US features of malignancy.

    Severe forms of congenital adrenal hyperplasia are potentially fatal if unrecognized and untreated. The aim of this study was to clarify the clinical presentation together with the chromosomal and laboratory associations in this syndrome. Twenty four patients diagnosed as congenital adrenal hyperplasia were referred from Children's Hospital, Cairo University, Egypt, for hormonal and chromosomal workup. The age ranged from eight months to 19 years with mean age of 3.18 years. Twenty two patients were diagnosed as classic congenital adrenal hyperplasia (CAH) syndrome. Severe salt wasting form was present in ten patients whereas simple virilisation was the presenting manifestation in twelve patients. Two patients presented as late onset congenital adrenal hyperplasia (LOCAH). The sex of rearing was female in 18 cases and male in six cases. Genitography and sonography confirmed the presence of female internal organs in all cases. Advanced bone age was evident by radiographic studies. Although the karyotyping was 46,XX in all cases, the diagnosed correct sex was delayed in six cases. Serum concentrations of 17-hydroxyprogesterone (17.OH.P), dehydroepiandrosterone sulfate (DHEAS), delta, 4-androstenedione (D4A), testosterone (T) and 11-deoxycortisol were all elevated as compared to controls. It was found that the adrenal androgens DHEAS, D4A and T were more elevated in salt losers when compared to simple virilising patients. However, this difference was statistically non-significant. The present study demonstrates that the clinical examination and laboratory investigations are necessary for the early detection and treatment of these cases to avoid major medical and psychological problems for the patients and their parents

    Several forms of congenital adrenal hyperplasia are potentially fatal if unrecognized and untreated. The aim of this study is to throw light on the clinical presentation together with chromosomal and laboratory associations in this syndrome. Twenty four patients diagnosed as congenital adrenal hyperplasia were referred from the Diabetic Endocrine Metabolic Pediatric Unit [DEMPU], Children's Hospital, Cairo University for hormonal and chromosomal workup. Twenty two patients were diagnosed as classic congenital adrenal hyperplasia (CAH) syndrome. Sever salt wasting form was present in ten patients whereas simple virilization was the presenting manifestation in twelve patients. Two patients presented as late onset congenital adrenal hyperplasia (LOCAH). The mean age was 3.18 years, ranging from eight months to 19 years. The sex of rearing was Female in 18 cases and male in six cases. Genitography and sonography confirmed the presence of female internal organs in all cases. Advanced bone age was evident by radiographic studies. Although the karyotyping was (46,XX) in all cases, the correct sex diagnosis was delayed in 6 cases. Serum concentrations of 17-hydroxyprogesterone (17.OH.P); Dehydroepiandrosterone sulfate (DHEAS); Delta,4-androstenedione (D 4 A); Testosterone and 11-deoxycortisol were all elevated in relation to controls. We found that the adrenal androgens DHEAS, delta 4A, and T were more elevated in salt losers when compared to simple virilizing patients. However, this difference was not of statistical significance. The present study demonstrates that clinical examination and laboratory investigations are necessary for early detection and treatment of hese cases to avoid major medical and psychological problems for the patients and their parents.

    Goblet cell hyperplasia and mucous hypersecretion contribute to the pathogenesis of chronic pulmonary diseases including cystic fibrosis, asthma, and chronic obstructive pulmonary disease. In the present work, mouse SAM pointed domain-containing ETS transcription factor (SPDEF) mRNA and protein were detected in subsets of epithelial cells lining the trachea, bronchi, and tracheal glands. SPDEF interacted with the C-terminal domain of thyroid transcription factor 1, activating transcription of genes expressed selectively in airway epithelial cells, including Sftpa, Scgb1a1, Foxj1, and Sox17. Expression of Spdef in the respiratory epithelium of adult transgenic mice caused goblet cell hyperplasia, inducing both acidic and neutral mucins in vivo, and stainined for both acidic and neutral mucins in vivo. SPDEF expression was increased at sites of goblet cell hyperplasia caused by IL-13 and dust mite allergen in a process that was dependent upon STAT-6. SPDEF was induced following intratracheal allergen exposure and after Th2 cytokine stimulation and was sufficient to cause goblet cell differentiation of Clara cells in vivo. PMID:17347682

    Surgical or conservative treatment of ACTH-producing tumors results in acute drop of the previously excessively high cortisol levels. The following associated pathophysiological changes also occur in the organism's recovery from stress, such as trauma, operation or chemotherapy of tumors. Both cases result in a regeneration of the immune system, which might even be exalted. The corresponding radiographic feature is the 'rebound' enlargement of the thymus occuring about six months after remission of hypercortisolism. Histological examination reveals benign thymus hyperplasia. Especially in cases of still unkown primary tumor the apperance of this anterior mediastinal mass can lead to misdiagnosis. We present the cases of two patients with diffuse thymic hyperplasia following surgical and medical correction of hypercortisolism. One patient suffered from classic Cushing's disease responding to transsphenoidal resection of an ACTH-secreting pituitary microadenoma. Six monsths later CT of the chest incidentally demonstrated an anterior mediastinal mass known as thymic hyperplasia. The second patient presented with an ectopic, still unknown source of ACTH-production. (orig./AJ) [de

    A patient with pituitary-dependent hypercortisolism, unresponsive to resection of nodules in the anterior lobe, is described. Histochemical stains of the nodules showed multiple, focal, cellular expansions of the fibrovascular stroma. Transitions between normal and expanded adenohypophysial acini were present. Immunoperoxidase stains for ACTH and other pituitary hormones revealed that these multiple foci contained an excess of ACTH-positive cells. Less than 10% of the cells in these foci were negative for ACTH and positive for other hormones. Serial sections showed that these foci of predominantly ACTH-producing acini were not connected. Clinical, morphological, and immunohistochemical data indicated that ACTH-cell hyperplasia caused Crushing's disease in this patient. Pathologic study of individual cases should concentrate on determining whether hyperplasia or adenoma exist at the time of surgical exploration of the pituitary gland, since this determination is important to proper treatment. Tentative criteria to recognize ACTH-cell hyperplasia are: 1. Multiple foci of ACTH laden cells. 2. A minor subpopulation of cells of alternate hormone series. 3. Expansion without destruction of acini in the adenohypophysis.

    Full Text Available Altered expression of DNA polymerase beta (Pol beta has been documented in a large percentage of human tumors. However, tumor prevalence or predisposition resulting from Pol beta over-expression has not yet been evaluated in a mouse model.We have recently developed a novel transgenic mouse model that over-expresses Pol beta. These mice present with an elevated incidence of spontaneous histologic lesions, including cataracts, hyperplasia of Brunner's gland and mucosal hyperplasia in the duodenum. In addition, osteogenic tumors in mice tails, such as osteoma and osteosarcoma were detected. This is the first report of elevated tumor incidence in a mouse model of Pol beta over-expression. These findings prompted an evaluation of human gastrointestinal tumors with regard to Pol beta expression. We observed elevated expression of Pol beta in stomach adenomas and thyroid follicular carcinomas, but reduced Pol beta expression in esophageal adenocarcinomas and squamous carcinomas.These data support the hypothesis that balanced and proficient base excision repair protein expression and base excision repair capacity is required for genome stability and protection from hyperplasia and tumor formation.

    To compare the post-thymectomy prognosis in different conditions of myasthenia gravis (MG) patients with thymus hyperplasia. Collecting medical record and carrying out the follow-up study of 123 myasthenia gravis patients with thymus hyperplasia who have underwent thymectomy during the period between 2003 and 2013. Dividing into different groups based on gender, age of onset, duration of disease and Myasthenia Gravis Association of America (MGFA) clinical classification to analyze different prognosis in different groups. Complete stable remission (CSR) was achieved in 71 of 123 patients (59.5%). There is no gender-related difference in achieving CSR. Patients with early onset of MG (≤40 years old) or disease duration less than 12 months had significantly higher CSR rates than those with late onset of MG (>40 years old) or disease duration more than 12 months respectively, while no difference was found in remission rate between MGFA clinical classification I and MGFA II. Myasthenia gravis patients with thymus hyperplasia who had thymectomy are proved to possess greater chance of achieving CSR. The onset age of disease and duration are the prognostic factors.

    Former studies evaluated echostructural and vascular patterns in ultrasound of the parathyroid gland to identify nodular hyperplasia in patients with secondary hyperparathyroidism due to chronic kidney disease. This prospective study aims to externally validate suggested ultrasound classifications. Parathyroid glands of 27 patients with secondary hyperparathyroidism undergoing parathyroidectomy were prospectively analyzed. Ultrasound including Doppler imaging was performed 1 day prior to surgery. Ultrasound data were available for 70 parathyroid glands. Echostructural and vascular scores according to previous studies were applied calculating the area under the receiver operating characteristic curve (AUROC). Overall correctness, sensitivity, and specificity of the investigated scores were assessed with the Youden index method. The Doppler score introduced by Vulpio and colleagues based on characteristic blood flow patterns in parathyroid glands showed an AUROC of 0.749 for the prediction of nodular hyperplasia with an overall correctness of 72.8%. Other ultrasound classifications based on blood flow patterns, as well as echostructure of the parathyroid gland displayed AUROCs of secondary hyperparathyroidism was externally validated for the first time. Other ultrasound scores fail as prognostic models in this study population. Doppler sonography of the parathyroid gland has prognostic capability to identify nodular hyperplasia as surrogate marker for patients with secondary hyperparathyroidism indicating the need for ablative or surgical treatment when failing conservative therapy.

    2015-01-01

    The Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) opposes laws and other policies that require nurses to report the results of screening for intimate partner violence (IPV) to law enforcement or other regulatory agencies without the consent of the woman who experiences the IPV. Nurses and other health care professionals, however, should become familiar with laws on mandatory reporting in their states and comply as applicable. Women should be universally screened for IPV in private, safe settings where health care is provided. Nurses are ideally positioned to screen for IPV for the purpose of initiating a referral for services and support when applicable. To protect the woman's safety, AWHONN supports policies that require a woman's consent before reporting occurs.

    Full Text Available This article analyses three works by Mexican painter Frida Kahlo: Las dos Fridas (The Two Fridas, Autorretrato en la frontera entre México y Estados Unidos (Self-Portrait on the Borderline between Mexico and the United States, and Lo que el agua me dio (What the Water Gave Me. Each work is first analyzed separately and then connected with the others. The analysis of the first two is guided by the national/foreign dichotomy present in Kahlo; the analysis of the third shows the overcoming of the dichotomy through the concept of intimate map – in which a feeble and ever-changing territorialization of memory via plastic expression comes to show.

    Intimate partner violence (IPV) is a major public health problem in the United States. Negative outcomes of IPV affect women's attainment and maintenance of employment. The purpose of this study was to develop a theoretical framework that described and explained the process by which women who have experienced IPV attain and maintain employment. Grounded theory methodology was used to analyze interviews of 34 women who had experienced IPV. Analysis suggested that women who had experienced IPV could attain employment; however, they had difficulty maintaining employment. Entanglement of work and IPV was experienced by all 34 participants because of the perpetrator controlling their appearance, sabotaging their work, interfering with their work, or controlling their finances. Some women described ways in which they disentangled work from IPV through a dynamic unraveling process, with periods of re-entanglement, resulting in job security and satisfaction. © 2016 The Author(s).

    Women who experience intimate partner violence (IPV) often do not perceive themselves as abused. This study sought to estimate the health effects of unperceived IPV (uIPV), taking violence-free women as the reference, and to compare the effects of uIPV with those of perceived IPV (pIPV). We performed a cross-sectional population study through telephone interviews of 2835 women aged 18 to 70 years living in the region of Madrid and having an ongoing intimate partner relationship or contact with a former partner in the preceding year. Based on 26 questions from the Conflict Tactics Scale-1 and the Enquête Nacional sur les Violences envers les Femmes en France and the question "Do you feel abused by your partner?" a variable was constructed in three categories, namely, the absence of IPV, uIPV and pIPV. Using logistic regression, we analyzed the association between health problems, medication use, health-service utilization and IPV (perceived and unperceived) vis-à-vis the absence of IPV. There were 247 cases of uIPV and 96 of pIPV (prevalences of 8.8% and 3.4%, respectively). The multivariate analysis showed that a substantial number of the outcomes explored were associated with uIPV, pIPV, or both. The highest odds ratios (ORs) were obtained for depression (Patient Health Questionnaire-9≥10) (uIPV: OR 3.4, 95% CI 2.4-3.8; and pIPV: 4.1, 95%CI 2.5-6.8). In most problems, the ORs did not significantly differ between the two types of IPV. uIPV is 2.6 times more frequent than pIPV and is associated with at least as many health problems as pIPV.

    The objective of this study is to analyze the association between intimate partner violence against women and maternal educational practice directed to children at the beginning of formal education. This is a cross-sectional study, carried out between 2013 and 2014, with 631 mother/child pairs, registered in the Family Health Strategy of the Health District II of the city of Recife, State of Pernambuco, Brazil. It integrates a prospective cohort study designed to investigate the consequences of exposure to intimate partner violence in relation to the child who was born between 2005 and 2006. The maternal educational practice has been assessed by the Parent-Child Conflict Tactics Scale and the intimate partner violence by a questionnaire adapted from the Multi-Country Study on Women's Health and Domestic Violence of the World Health Organization. Intimate partner violence referred to the last 12 months and was defined by specific acts of psychological, physical, and sexual violence inflicted to women by the partner. The crude and adjusted prevalence ratios were estimated for the association studied, using log-binomial regression. The prevalence of intimate partner violence was 24.4%, and violent maternal educational practice was 93.8%. The use of non-violent discipline was mentioned by 97.6% of the women, coexisting with violent strategies of discipline. Children whose mothers reported intimate partner violence presented a higher chance of suffering psychological aggression (PR = 2.2; 95%CI 1.0-4.7). The violence suffered by the mother interferes in the parental education. The findings show high prevalence of violent maternal educational practice, pointing to the need for interventions that minimize the damage of violence in women and children.

    Full Text Available Nodular regenerative hyperplasia (NRH of the liver is often associated with rheumatologic or lymphoproliferative disorders and a cause of portal hypertension in some patients. We report the case of a 71-year-old patient with celiac disease and unexplained portal hypertension. Biopsy of the liver revealed NRH as the underlying cause. The patient did not suffer from an autoimmune, rheumatologic or lymphoproliferative disease. A thrombophilic disorder that might cause NRH was ruled out. Celiac disease is often associated with mild elevation of liver enzymes and steatosis of the liver, but the association with NRH was described in only a few patients. We discuss the possible relationship of celiac disease and NRH.

    Full Text Available Abstract Background Domestic violence has unwanted effects on the physical and psychological well-being of women, which have been recognized globally as an important public health problem. Violence perpetrated by intimate partner is one form of domestic violence, a serious human rights abuse and a public health issue, among refugees owing to its substantial consequences for women's physical, mental and reproductive health problems. Because the incidents are under-reported, the true scale of the problem is unknown and unexamined among refugee women in Ethiopia. Thus, this study aim to assess the magnitude of intimate partner physical violence and associated factors among women in Shimelba refugee camp, Northern Ethiopia. Methods A community-based cross-sectional study was conducted among a sample of 422 refugee women from March to April 2011. A simple random sampling method was used to select the study subjects from seven zones of the refugee camp. Census was done to identify all households with women having an intimate partner. A pre-tested interviewer guided structured questionnaire was used for data collection. Data were entered, cleaned and analyzed using SPSS software version 16.0. Descriptive, bivariate and multivariate logistic regression analyses were done where applicable. A p-value less than 0.05 with 95% CI were set and used as a cut-off point to examine the statistical association between the explanatory and outcome variables. Results The prevalence of physical violence in the last 12 months and lifetime were 107(25.5% and 131(31.0% respectively. The commonest forms of physical violence reported included slapping 101(61.6% and throwing objects 32(19.5%. Significant risk factors associated with experiencing physical violence were being a farmer (AOR = 3.0[95%CI: 1.7, 5.5], knowing women in neighborhood whose husband to beat them (AOR = 1.87[95%CI: 1.0, 3.5], being a Muslim (AOR = 2.4 [95%C.I: 1.107, 5.5], and having a drunkard partner

    The human prostate gland is one of the only internal organs that continue to enlarge throughout adulthood. The specific mechanisms that regulate this growth, as well as the pathological changes leading to the phenotype observed in the disease benign prostatic hyperplasia (BPH), are essentially unknown. Recent studies and their associated findings have made clear that many complex alterations occur, involving persistent and chronic inflammation, circulating hormonal level deregulation, and aberrant wound repair processes. BPH has been etiologically characterized as a progressive, albeit discontinuous, hyperplasia of both the glandular epithelial and stromal cell compartments coordinately yielding an expansion of the prostate gland and clinical symptoms. Interestingly, the inflammatory and repair responses observed in BPH are also key components of general wound repair in post-natal tissues. These responses include altered expression of chemokines, cytokines, matrix remodeling factors, chronic inflammatory processes, altered immune surveillance and recognition, as well as the formation of a prototypical ‘reactive’ stroma which is similar to that observed across various fibroplasias and malignancies of a variety of tissue sites. Stromal tissue, both embryonic mesenchyme, and adult reactive stroma myofibroblasts, has been shown to exert potent and functional regulatory control over epithelial proliferation and differentiation as well as immunoresponsive modulation. Thus, the functional biology of a reactive stroma, within the context of an adult disease typified by epithelial and stromal aberrant hyperplasia, is critical to understand within the context of prostate disease and beyond. The mechanisms that regulate reactive stroma biology in BPH represent targets of opportunity for new therapeutic approaches that may extend to other tissue contexts. Accordingly, this review seeks to address the dissection of important factors, signaling pathways, genes, and other

    Highlights: • Rats and mice orally administered with nicotine tartrate for total of 4 weeks. • No treatment-related death or whole body toxicity observed in any of the groups. • Urothelium showed simple hyperplasia in treated rats and mice. • No significant change in BrdU labeling index or SEM classification of urothelium. - Abstract: Tobacco smoking is a major risk factor for multiple human cancers including urinary bladder carcinoma. Tobacco smoke is a complex mixture containing chemicals that are known carcinogens in humans and/or animals. Aromatic amines a major class of DNA-reactive carcinogens in cigarette smoke, are not present at sufficiently high levels to fully explain the incidence of bladder cancer in cigarette smokers. Other agents in tobacco smoke could be excreted in urine and enhance the carcinogenic process by increasing urothelial cell proliferation. Nicotine is one such major component, as it has been shown to induce cell proliferation in multiple cell types in vitro. However, in vivo evidence specifically for the urothelium is lacking. We previously showed that cigarette smoke induces increased urothelial cell proliferation in mice. In the present study, urothelial proliferative and cytotoxic effects were examined after nicotine treatment in mice and rats. Nicotine hydrogen tartrate was administered in drinking water to rats (52 ppm nicotine) and mice (514 ppm nicotine) for 4 weeks and urothelial changes were evaluated. Histopathologically, 7/10 rats and 4/10 mice showed simple hyperplasia following nicotine treatment compared to none in the controls. Rats had an increased mean BrdU labeling index compared to controls, although it was not statistically significantly elevated in either species. Scanning electron microscopic visualization of the urothelium did not reveal significant cytotoxicity. These findings suggest that oral nicotine administration induced urothelial hyperplasia (increased cell proliferation), possibly due to a

    Hemimandibular hyperplasia (HH), also known as hemimandibular hypertrophy, is characterised by excessive unilateral three-dimensional growth of the mandible after birth. Vertical unilateral elongation of the mandible becomes clinically evident as a rare form of vertical facial asymmetry. Aberrant growth of the facial skeleton affects the developing dentition and the dental compensatory mechanism is usually unable to maintain optimal occlusal relationships. The resulting malocclusion is effectively managed by combined surgical-orthodontic care to address the facial, skeletal and dental problems that confront clinicians. Orthodontists are advised to assess patients with HH during the post-treatment retention stage for continuing mandibular growth and assess the stability of treatment outcomes with long-term follow-up and records as required. To present a case of hemimandibular hyperplasia treated successfully by combined surgical-orthodontic care and evaluated for stability over a seven-year follow-up period. Surgical-orthodontic management was accomplished in four stages: 1) pre-surgical orthodontic; 21 surgical; 3) post-surgical orthodontic; and 4) post-treatment orthodontic retention. Complete orthodontic records, including extra- and intra-oral photographs, study models, and cephalograms plus panoramic radiographs were taken at the pretreatment, post-treatment, and seven-year orthodontic retention time-points. Facial, skeletal and dental goals were achieved in the three planes of space and the long-term stability of the treatment results was shown during a post-treatment orthodontic retention period of seven years. Hemimandibular hyperplasia is a true growth anomaly which may be managed effectively. Clinicians may expect successful long-term correction and stability by utilising a comprehensive surgical-orthodontic treatment approach.

    Homicide is an important cause of premature mortality globally, but evidence for the magnitude of homicides by intimate partners is scarce and hampered by the large amount of missing information about the victim-offender relationship. The objective of the study was to estimate global and regional prevalence of intimate partner homicide. A systematic search of five databases (Medline, Global Health, Embase, Social Policy, and Web of Science) yielded 2167 abstracts, and resulted in the inclusion of 118 full-text articles with 1122 estimates of the prevalence of intimate partner homicide after double-blind screening. All studies were included that reported the number or proportion of women or men who were murdered by an intimate partner in a country, province, or town, using an inclusive definition of an intimate partner. Additionally, a survey of official sources of 169 countries provided a further 53 estimates. We selected one estimate per country-year using a quality assessment decision algorithm. The median prevalence of intimate partner homicide was calculated by country and region overall, and for women and men separately. Data were obtained for 66 countries. Overall 13·5% (IQR 9·2-18·2) of homicides were committed by an intimate partner, and this proportion was six times higher for female homicides than for male homicides (38·6%, 30·8-45·3, vs 6·3%, 3·1-6·3). Median percentages for all (male and female) and female intimate partner homicide were highest in high-income countries (all, 14·9%, 9·2-18·2; female homicide, 41·2%, 30·8-44·5) and in southeast Asia (18·8%, 11·3-18·8; 58·8%, 58·8-58·8). Adjustments to account for unknown victim-offender relationships generally increased the prevalence, suggesting that results presented are conservative. At least one in seven homicides globally and more than a third of female homicides are perpetrated by an intimate partner. Such violence commonly represents the culmination of a long history of abuse

    2017-01-01

    Combining DHS data for 580,000 women from 30 different countries in Sub-Saharan Africa, we analyze how both the incidence and the acceptance of intimate partner violence vary across time and space, in a region with record high levels of violence against women. We review the existing literature regarding the impact of resources on intimate partner violence, extracting testable and often conflicting hypotheses at the micro and macro level, and on the interaction across levels. We propose to ext...

  18. The Remaking of Erotic and Intimate Life The Remaking of Erotic and Intimate Life

    Directory of Open Access Journals (Sweden)

    2009-05-01

    Full Text Available We are living in the midst of an unprecedented transformation of erotic and intimate life. Although this has been the subject of much controversy, most people have taken for granted the results of the changes, with little awareness of how things have changed, and how significant the changes have been. The article explores three traps that commentators fall into. The first is a mindless progressivism that assumes that all is for the best in all possible worlds. The second is a declinist approach, which assumes that all change is for the worst and that the quality of our morality – for which we can read sexual behaviour and values – is in hopeless decline. The third approach assumes continuity: yes, superficial things have changed, but in essence power structures have remained resilient. Subforms of the continuist approach are described, derived from feminist, queer, and anti neo-liberal critiques. Against these broad analytical approaches, the article affirms the importance of a historical approach. This would recognise that change has been uneven, but transforming nevertheless, and for the better. What makes them so significant is that they have largely been grass roots led: a true remaking of everyday life under the pressure of globalisation, detraditionalisation and heightened individualisation. In drawing up a balance sheet of the great transition we must conclude that a new world is emerging, a world we have won.Vivimos en medio de una transformación sin precedentes de la vida erótica e intima. A pesar de que este asunto ha sido objeto de una amplia controversia, han sido muchos los que han dado por supuestos los resultados de los cambios, con escaso conocimiento de cómo han cambiado las cosas y hasta qué punto los cambios han sido significativos.

    Full Text Available Introduction: The purposes of this study were to assess the extent to which latent trajectories of female intimate partner violence (IPV victimization exist; and, if so, use negative childhood experiences to predict trajectory membership.Methods: We collected data from 1,575 women at 5 time-points regarding experiences during adolescence and their 4 years of college. We used latent class growth analysis to fit a series of personcentered, longitudinal models ranging from 1 to 5 trajectories. Once the best-fitting model was selected, we used negative childhood experience variables—sexual abuse, physical abuse, and witnessing domestic violence—to predict most-likely trajectory membership via multinomial logistic regression.Results: A 5-trajectory model best fit the data both statistically and in terms of interpretability. The trajectories across time were interpreted as low or no IPV, low to moderate IPV, moderate to low IPV, high to moderate IPV, and high and increasing IPV, respectively. Negative childhood experiences differentiated trajectory membership, somewhat, with childhood sexual abuse as a consistent predictor of membership in elevated IPV trajectories.Conclusion: Our analyses show how IPV risk changes over time and in different ways. These differential patterns of IPV suggest the need for prevention strategies tailored for women that consider victimization experiences in childhood and early adulthood.

    2017-01-01

    Intimate partner violence (IPV) has been a well-studied problem in the past psychological literature, especially through its classical methodology such as qualitative, quantitative and mixed methods. This article introduces two basic stochastic models as an alternative approach to simulate the short and long-term dynamics of a couple at risk of IPV. In both models, the members of the couple may assume a finite number of states, updating them in a probabilistic way at discrete time steps. After defining the transition probabilities, we first analyze the evolution of the couple in isolation and then we consider the case in which the individuals modify their behavior depending on the perceived violence from other couples in their environment or based on the perceived informal social support. While high perceived violence in other couples may converge toward the own presence of IPV by means a gender-specific transmission, the gender differences fade-out in the case of received informal social support. Despite the simplicity of the two stochastic models, they generate results which compare well with past experimental studies about IPV and they give important practical implications for prevention intervention in this field.

    2003-07-01

    The WHO has declared that violence is a leading worldwide public health problem with intimate partner violence one of the most common forms of violence against women (2002). Health care providers are frequently among the first to see victims of intimate partner violence and must strive to provide appropriate and effective care to abused women. Violence by intimate partners can be prevented. Occupational health nurses have a unique opportunity to intervene with abused women. Routine screening for intimate partner violence increases the likelihood of violence identification, leading to early intervention that may prevent trauma and injury. Occupational health nurses can foster a caring and confidential workplace where abused women feel safe to disclose the violence in their lives and trust that the nurse will provide treatment. A safe and healthy workplace, where abused women feel comfortable disclosing intimate partner violence and seeking treatment may also protect coworkers from the stress and violence that may potentially affect them. Occupational health nurses need to add screening for and treatment of intimate partner violence to their current health promotion and prevention activities to benefit all employees.

    A novel short-term organ culture system was used to evaluate intimal permeability changes by measuring aortic [ 14 C]methylated albumin accumulation. Aortic plugs were removed from the upper thoracic aorta of male guinea pigs and maintained in serum-free media. The accumulation of [ 14 C]albumin in the intimal-medial layer was determined after a 5 h incubation. In preliminary studies, albumin recovered from intimal-injured aortic plugs was significantly greater than those from non-injured plugs. Aortic plugs from streptozotocin-treated guinea pigs, diabetic for 3 weeks, also accumulated significantly more [ 14 C]albumin than plugs from nondiabetic controls. Histological changes were not observed in the aorta of either the diabetic or control group. A strong significant inverse correlation was found between plasma ascorbic acid levels and [ 14 C]-activity recovered from aortic plugs. This study demonstrates a simple and rapid method for assessing aortic permeability changes under a well-defined in vitro system, and suggests that vascular permeability changes in the streptozotocin-diabetic guinea pig may be associated with an ascorbic acid deficit

    Clinical trials of selective RAF inhibitors in patients with melanoma tumors harboring activated BRAFV600E have produced very promising results, and a RAF inhibitor has been approved for treatment of advanced melanoma. However, about a third of patients developed resectable skin tumors during the course of trials. This is likely related to observations that RAF inhibitors activate extracellular signal-regulated kinase (ERK) signaling, stimulate proliferation, and induce epithelial hyperplasia in preclinical models. Because these findings raise safety concerns about RAF inhibitor development, we further investigated the underlying mechanisms. We showed that the RAF inhibitor PF-04880594 induces ERK phosphorylation and RAF dimerization in those epithelial tissues that undergo hyperplasia. Hyperplasia and ERK hyperphosphorylation are prevented by treatment with the mitogen-activated protein/extracellular signal-regulated kinase (MEK) inhibitor PD-0325901 at exposures that extrapolate to clinically well-tolerated doses. To facilitate mechanistic and toxicologic studies, we developed a three-dimensional cell culture model of epithelial layering that recapitulated the RAF inhibitor-induced hyperplasia and reversal by MEK inhibitor in vitro. We also showed that PF-04880594 stimulates production of the inflammatory cytokine interleukin 8 in HL-60 cells, suggesting a possible mechanism for the skin flushing observed in dogs. The complete inhibition of hyperplasia by MEK inhibitor in epithelial tissues does not seem to reduce RAF inhibitor efficacy and, in fact, allows doubling of the PF-04880594 dose without toxicity usually associated with such doses. These findings indicated that combination treatment with MEK inhibitors might greatly increase the safety and therapeutic index of RAF inhibitors for the treatment of melanoma and other cancers. ©2012 AACR.

    The presence of aberrant thyroid tissue in the lateral neck is very rare. In addition, nodular hyperplasia in ectopic thyroid has rarely been reported. Due to the unusual location, the presence of lateral aberrant thyroid tissue could be misdiagnosed as a lymphadenopathy, neurogenic tumor, etc. We report on a case of nodular hyperplasia arising from the right lateral aberrant thyroid tissue.

    To study the Incidence of endometrial hyperplasia in perimenupausal women presenting with polymenorrhagia/menorrhagia. This observational study was conducted at Gynae 'B' unit of Khyber Teaching Hospital Peshawar from January 2000 to December 2001. One hundred consecutive patients who presented at Gynaecology OPD with Polymenorrhagia/ Menorrhagia were registered and incidence of endometrial hyperplasia evaluated in them. All women were above 45 years of age. Post-menopausal bleeding cases were excluded from the study. Out of 100 patients, 15 patients were found to have endometrial hyperplasia, 10 patients (66.6%) simple cystic hyperplasia, 3 patients (20.0%) had adenomotous hyperplasia, 2 patients (13.3%) had atypical hyperplasia, 8 patients (53.3%) with menorrhagia, 1 (6.6%) with polymenorrhagia, and 6 patients (40.0%) with polymenorrhoea. Duration of symptoms was from 4 months to 1 year. Thirteen (86.6%) patients were treated medically, 5 patients (33.33%) needed surgical treatment following medical treatment, 2 patients (13.3%) underwent Total Abdominal Hysterectomy (TAH) and Bilateral Salpingooophorectomy (BSO) who were 51-53 years of age with atypical hyperplasia. endometrial hyperplasia is a pre-malignant condition; if treated in time, incidence can be reduced and early treatment can increase life expectancy and quality in women over age of 45 years.

    survey variant that depicted the wife as intentionally violating gendered standards of behavior were more likely to condone intimate partner violence in a greater number of vignettes (adjusted odds ratios [AORs] ranged from 3.87 to 5.74, with all p < 0.001, while participants assigned the survey variant that depicted the wife as unintentionally violating these standards were less likely to condone intimate partner violence (AORs ranged from 0.29 to 0.70, with p-values ranging from <0.001 to 0.07. The analysis of perceived norms displayed similar patterns, but the effects were slightly smaller in magnitude: participants assigned to the "intentional" survey variant were more likely to perceive intimate partner violence as normative (AORs ranged from 2.05 to 3.51, with all p < 0.001, while participants assigned to the "unintentional" survey variant were less likely to perceive intimate partner violence as normative (AORs ranged from 0.49 to 0.65, with p-values ranging from <0.001 to 0.14. The primary limitations of this study are that our assessments of personal beliefs and perceived norms could have been measured with error and that our findings may not generalize beyond rural Uganda.Contextual information about the circumstances under which women in hypothetical vignettes were perceived to violate gendered standards of behavior had a significant influence on the extent to which study participants endorsed the acceptability of intimate partner violence. Researchers aiming to assess personal beliefs or perceived norms about intimate partner violence should attempt to eliminate, as much as possible, ambiguities in vignettes and questions administered to study participants.ClinicalTrials.gov NCT02202824.

    This study explored how an alcohol education program might be structured to effectively educate college students about the consequences of alcohol use. The primary hypothesis tested stated that individuals would vary significantly in the amount of knowledge learned from a structured alcohol education workshop, based on the degree of familial or social exposure s/he has had to alcohol abuse. Social learning variables of locus of control, dogmatism, and expectancy for risk were tested for interaction with degree of exposure, to determine their influence on learning. A pretest-posttest control group was employed with a sample of 66 undergraduate college students. A four hour alcohol education program was administered to teach cognitive information and fact about alcohol, with a goal of facilitating responsible use/nonuse of alcohol. The Student Drinking Questionnaire measured acquisition of knowledge. The Adult Nowicki-Strickland Internal/External Scale measured locus of control, and Schultze's Short Dogmatism Scale measured dogmatism. The researcher developed an instrument for expectancy for risk. Multiple regression analyses yielded prediction equations for the variables under study. For the sample group, results demonstrated that a significant portion of the variance in the residualized posttest scores was accounted for by level of exposure and dogmatism. When the sample was blocked according to intimate or social exposure, dogmatism was the only construct entering the regression equation at a significant level for the intimate exposure group. None of the constructs were able to predict any of the residualized posttest scores for the social exposure group. It was concluded that: (1) Students in the sample learned differentially based on the degree of intimate exposure of alcohol; (2) Dogmatism is a moderating variable with acquisition of knowledge for those intimately exposed to alcohol abuse, but locus of control and expectancy for risk are not; and (3) Further

    2015-01-01

    Full Text Available Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH is a rare clinical condition with only about 100 cases reported in the literature. It is characterized by primary hyperplasia of pulmonary neuroendocrine cells (PNECs which are specialized epithelial cells located throughout the entire respiratory tract, from the trachea to the terminal airways. DIPNECH appears in various forms that include diffuse proliferation of scattered neuroendocrine cells, small nodules, or a linear proliferation. It is usually seen in middle-aged, nonsmoking women with symptoms of cough, dyspnea, and wheezing. We present a 45-year-old, nonsmoking woman who presented with symptoms of DIPNECH associated with bilateral pulmonary nodules and left hilar adenopathy. Of interest, DIPNECH in our patient was associated with metastatic pulmonary carcinoids, papillary carcinoma of the left breast, oncocytoma and angiomyolipoma of her left kidney, and cortical nodules suggestive of tuberous sclerosis. She had video assisted thoracoscopic surgery (VATS, modified radical mastectomy with reconstruction, and radical nephrectomy. She is currently symptom-free most of the time with over two years of follow-up.

    The association between breast cancer development and exogenous hormone use (EHU) is suggested by indirect clinical evidence. We undertook this study to better define the relationship that EHU has with proliferative fibrocystic change (PFC) and atypical hyperplasia (AH). Women diagnosed with AH without associated carcinoma from January 1990 to December 1999 were compared with control subjects who underwent breast biopsy procedures during the same interval and who were diagnosed with either a proliferative fibrocystic change (PFC) or a nonproliferative fibrocystic change (NPFC). EHU was defined as the use of estrogen or progesterone taken together or separately within 3 months of biopsy. EHU was significantly higher in patients with AH compared with women with NPFC (P =.01). This observation was also significant if all proliferative change (both AH and PFC) was compared with NPFC (P =.03); it was not significant when PFC alone was compared with NPFC. No significant difference in EHU was demonstrated between women with AH and those with PFC. There is strong association between AH and EHU. These results support the theory that a continuum exists between hyperplasia and carcinoma and that EHU may influence the transition from one to the other in an undefined subset of women. We encourage our patients with AH to discontinue EHU.

    All twelve Beagle dogs undergoing long-term therapy (26 weeks) with the immunosuppressive drug cyclosporine-A (30 mg/kg), developed cutaneous papillomatous hyperplasia. By week 7 all dogs developed generalized lesions distributed over the entire body. These occurred as irregular, oval, sessile, unpigmented, firm masses. The incidence and severity of the skin lesions varied among dogs and anatomic site, with no correlation to the blood level of cyclosporine. Microscopic analysis revealed that the epidermis formed short papillary folds on broad fibrovascular stalks and was hyperkeratotic and acanthotic. Mild hyperplasia of hair follicles and sebaceous glands was also evident. A mild diffuse infiltrate of lymphocytes and plasma cells was present in the papillary dermis. No histopathologic changes typical of papillomavirus infection were identified, nor were papillomavirus group-specific antigens or viral DNA detected. Other cutaneous side effects included hyperkeratosis of footpads, increased growth of hair and nails, and hyperkeratinization of the haired skin of the prepuce. All cutaneous lesions regressed spontaneously within 8 weeks following termination of cyclosporine administration. The hyperplastic lesions may have resulted from the action of cyclosporine via the T-lymphocyte system. Conversely a direct action of this drug on epithelial cells may have stimulated proliferation and keratinization.

    Claudin (Cld)-4 is one of the dominant Clds expressed in the kidney and urinary tract, including selective segments of renal nephrons and the entire urothelium from the pelvis to the bladder. We generated Cldn4 −/− mice and found that these mice had increased mortality due to hydronephrosis of relatively late onset. While the renal nephrons of Cldn4 −/− mice showed a concomitant diminution of Cld8 expression at tight junction (TJ), accumulation of Cld3 at TJ was markedly enhanced in compensation and the overall TJ structure was unaffected. Nonetheless, Cldn4 −/− mice showed slightly yet significantly increased fractional excretion of Ca2+ and Cl−, suggesting a role of Cld4 in the specific reabsorption of these ions via a paracellular route. Although the urine volume tended to be increased concordantly, Cldn4 −/− mice were capable of concentrating urine normally on dehydration, with no evidence of diabetes insipidus. In the urothelium, the formation of TJs and uroplaques as well as the gross barrier function were also unaffected. However, intravenous pyelography analysis indicated retarded urine flow prior to hydronephrosis. Histological examination revealed diffuse hyperplasia and a thickening of pelvic and ureteral urothelial layers with markedly increased BrdU uptake in vivo. These results suggest that progressive hydronephrosis in Cldn4 −/− mice arises from urinary tract obstruction due to urothelial hyperplasia, and that Cld4 plays an important role in maintaining the homeostatic integrity of normal urothelium.

    Jaques Waisberg

    Full Text Available CONTEXT AND OBJECTIVE: Castleman's disease, or giant lymph node hyperplasia, is a rare disorder of the lymphoid tissue that causes lymph node enlargement. It is considered benign in its localized form, but aggressive in the multicentric type. The definitive diagnosis is based on postoperative pathological findings. The aim here was to describe a case of retroperitoneal unicentric Castleman's disease in the retroperitoneum. CASE REPORT: A 61-year old white male with weight loss and listlessness presented with moderate arterial hypertension and leukopenia. Abdominal tomography revealed a 5 x 4 x 5 cm oval mass of low attenuation, with inner calcification and intense enhancement on intravenous contrast, located in the retroperitoneal region, between the left kidney and the aorta, at the renal hilus. Exploratory laparotomy revealed a non-pulsatile solid oval mass situated in the retroperitoneum, adjacent to the left renal hilus. The retroperitoneal lesion was removed in its entirety. Examination of frozen samples revealed benign lymph node tissue and histopathological examination of the surgical sample revealed hyaline-vascular giant lymph node hyperplasia (Castleman's disease. The patient was discharged on the 12th day without significant events. Two months after the operation, the patient was readmitted with severe cardiac insufficiency, acute renal failure and bronchopneumonia, which progressed to acute respiratory insufficiency, sepsis and death.

    We evaluated the protective effects of fermented dairy products (FDPs) in an infection model, using the mouse pathogen Citrobacter rodentium (CR). Treatment of mice with FDP formulas A, B, and C or a control product did not affect CR colonization, organ specificity, or attaching and effacing lesion formation. Fermented dairy product A (FDP-A), but neither the supernatant from FDP-A nor β-irradiated (IR) FDP-A, caused a significant reduction in colonic crypt hyperplasia and CR-associated pathology. Profiling the gut microbiota revealed that IR-FDP-A promoted higher levels of phylotypes belonging to Alcaligenaceae and a decrease in Lachnospiraceae (Ruminococcus) during CR infection. Conversely, FDP-A prevented a decrease in Ruminococcus and increased Turicibacteraceae (Turicibacter). Importantly, loss of Ruminococcus and Turicibacter has been associated with susceptibility to dextran sodium sulfate-induced colitis. Our results demonstrate that viable bacteria in FDP-A reduced CR-induced colonic crypt hyperplasia and prevented the loss of key bacterial genera that may contribute to disease pathology. © The Author 2014.

    The precise location and progression of anastomotic hyperplasia and its possible relationship to flow disturbances was investigated in femoro-femoral Dacron grafts in 28 dogs. In 13 grafts, the outflow from the end-to-side downstream anastomosis was bidirectional (BDO), and in 15 it was unidirectional (UDO) (distally). Grafts were electively removed at intervals of two to 196 days or at the time of thrombosis. Each anastomosis and adjacent artery was perfusion-fixed and sectioned sagittally. The mean sagittal section was projected onto a digitized pad, and the total area of hyperplasia internal to the arterial internal elastic lamina and within the adjacent graft was integrated by computer. The location of the hyperplasia was compared with previously established sites of flow separation and stagnation. The observation was made that hyperplasia is significantly greater at the downstream, as compared with the upstream, anastomosis in both groups (BDO = p less than 0.001 and UDO = p less than 0.001) (analysis of variance for independent groups). Furthermore, this downstream hyperplasia was progressive with time (BDO p less than 0.01) (UDO p less than 0.01); Spearman Rank Correlation. There was no significant increase in the extent of downstream hyperplasia where flow separation was known to be greater (BDO). Five grafts failed (three BDO, two UDO), as a result of complete occlusion of the downstream anastomosis by fibrous hyperplasia. Transmission electron microscopy showed the hyperplasia to consist of collagen-producing smooth muscle cells. Anastomotic hyperplasia is significantly greater at the downstream anastomosis, is progressive with time, and is the primary cause of failure of Dacron arterial grafts in this model. Quantitative analysis of downstream anastomotic hyperplasia may be a valuable measure of the biocompatibility of Dacron grafts. Images Fig. 2. Fig. 3. Fig. 5. Fig. 6. Fig. 7. Fig. 8. PMID:6219641

    The mental and physical health consequences of intimate partner violence (IPV) have been well established, yet little is known about the impact of violence on a woman's ability to obtain and maintain housing. This cross-sectional study examines the relationship between recent IPV and housing instability among a representative sample of California women. It is expected that women who have experienced IPV will be at increased risk for housing instability as evidenced by: (1) late rent or mortgage, (2) frequent moves because of difficulty obtaining affordable housing, and/or (3) without their own housing. Data were taken from the 2003 California Women's Health Survey, a population-based, random-digit-dial, annual probability survey of adult California women (N=3619). Logistic regressions were used to predict housing instability in the past 12 months, adjusting for the following covariates; age, race/ethnicity, education, poverty status, marital status, children in the household, and past year IPV. In the multivariate model, age, race/ethnicity, marital status, poverty, and IPV were significant predictors of housing instability. After adjusting for all covariates, women who experienced IPV in the last year had almost four times the odds of reporting housing instability than women who did not experience IPV (adjusted odds ratio=3.98, 95% confidence interval: 2.94-5.39). This study found that IPV was associated with housing instability among California women. Future prospective studies are needed to learn more about the nature and direction of the relationship between IPV and housing instability and the possible associated negative health consequences.

  2. Increased Expression of FoxM1 Transcription Factor in Respiratory Epithelium Inhibits Lung Sacculation and Causes Clara Cell Hyperplasia

    Foxm1 is a member of the Forkhead Box (Fox) family of transcription factors. Foxm1 (previously called Foxm1b, HFH-11B, Trident, Win, or MPP2) is expressed in multiple cell types and plays important roles in cellular proliferation, differentiation and tumorigenesis. Genetic deletion of Foxm1 from mouse respiratory epithelium during initial stages of lung development inhibits lung maturation and causes respiratory failure after birth. However, the role of Foxm1 during postnatal lung morphogenesis remains unknown. In the present study, Foxm1 expression was detected in epithelial cells of conducting and peripheral airways and changing dynamically with lung maturation. To discern the biological role of Foxm1 in the prenatal and postnatal lung, a novel transgenic mouse line that expresses a constitutively active form of FoxM1 (FoxM1 N-terminal deletion mutant or FoxM1-ΔN) under the control of lung epithelial-specific SPC promoter was produced. Expression of the FoxM1-ΔN transgene during embryogenesis caused epithelial hyperplasia, inhibited lung sacculation and expression of the type II epithelial marker, pro-SPC. Expression of FoxM1-ΔN mutant during the postnatal period did not influence alveologenesis but caused focal airway hyperplasia and increased proliferation of Clara cells. Likewise, expression of FoxM1-ΔN mutant in conducting airways with Scgb1a1 promoter was sufficient to induce Clara cell hyperplasia. Furthermore, FoxM1-ΔN cooperated with activated K-Ras to induce lung tumor growth in vivo. Increased activity of Foxm1 altered lung sacculation, induced proliferation in the respiratory epithelium and accelerated lung tumor growth, indicating that precise regulation of Foxm1 is critical for normal lung morphogenesis and development of lung cancer.

  3. The roles of phosphorylation and SHAGGY-like protein kinases in geminivirus C4 protein induced hyperplasia.

    Directory of Open Access Journals (Sweden)

    Katherine Mills-Lujan

    Full Text Available Even though plant cells are highly plastic, plants only develop hyperplasia under very specific abiotic and biotic stresses, such as when exposed to pathogens like Beet curly top virus (BCTV. The C4 protein of BCTV is sufficient to induce hyperplasia and alter Arabidopsis development. It was previously shown that C4 interacts with two Arabidopsis Shaggy-like protein kinases, AtSK21 and 23, which are negative regulators of brassinosteroid (BR hormone signaling. Here we show that the C4 protein interacts with five additional AtSK family members. Bikinin, a competitive inhibitor of the seven AtSK family members that interact with C4, induced hyperplasia similar to that induced by the C4 protein. The Ser49 residue of C4 was found to be critical for C4 function, since: 1 mutagenesis of Ser49 to Ala abolished the C4-induced phenotype, abolished C4/AtSK interactions, and resulted in a mutant protein that failed to induce changes in the BR signaling pathway; 2 Ser49 is phosphorylated in planta; and 3 plant-encoded AtSKs must be catalytically active to interact with C4. A C4 N-myristoylation site mutant that does not localize to the plasma membrane and does not induce a phenotype, retained the ability to bind AtSKs. Taken together, these results suggest that plasma membrane associated C4 interacts with and co-opts multiple AtSKs to promote its own phosphorylation and activation to subsequently compromise cell cycle control.

    Benign prostatic hyperplasia (BPH) and prostate cancer are among the most common diseases of the prostate gland and represent significant burdens for patients and health-care systems in many countries. The two diseases share traits such as hormone-dependent growth and response to antiandrogen...... therapy. Furthermore, risk factors such as prostate inflammation and metabolic disruption have key roles in the development of both diseases. Despite these commonalities, BPH and prostate cancer exhibit important differences in terms of histology and localization. Although large-scale epidemiological...... studies have shown that men with BPH have an increased risk of prostate cancer and prostate-cancer-related mortality, it remains unclear whether this association reflects a causal link, shared risk factors or pathophysiological mechanisms, or detection bias upon statistical analysis.

    Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare disease characterized by single or multiple angiomatous lesions typically located on the scalp and the face. We present a retrospective analysis of 9 cases of ALHE. The lesions appeared largely as multiple grouped papules or, in some cases, subcutaneous nodules, located mainly on the scalp, particularly around the ear. We also observed lesions in atypical locations, such as areas of the head other than the scalp, and the shoulder, neck, and forearm. At these sites the lesions had an atypical clinical appearance that made diagnosis difficult; this should be borne in mind in patients with single, well-delimited lesions with a vascular appearance and superficial ulceration or crusting. Surgery was the most common treatment in our series, and even though ALHE is considered a benign condition, recurrence was common. Copyright © 2012 Elsevier España, S.L. and AEDV.

    Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare disorder characterized by a proliferation of neuroendocrine cells within the lung. It is classically described as a disease with persistent cough, dyspnea and wheezing in non-smoker middle aged females. CT of the chest reveals diffuse air trapping with mosaic pattern. We present two cases of DIPNECH that were sent to our department to perform a lung biopsy with the diagnostic suspicion of diffuse interstitial disease. Both cases were women with a history of chronic cough and moderate effort dyspnea. The aim of this paper is that physicians take into account this diagnostic entity before treating as an asthmatic a patient with these characteristics, not forgetting that they are prenoplastic lesions.

    Nineteen dogs with clinical signs of benign prostatic hyperplasia (BPH) were given a subcutaneous injection of medroxyprogesterone acetate (MPA). At the first follow-up four to six weeks after treatment, 16 (84%) showed no signs of prostatic disease, and in 10 (53%) radiography revealed that the prostate had decreased in size. The dogs were followed for an average of 17 months. Twelve (64%) showed no signs of prostatic disease for at least 10 months. Relapses occurred in 10 between 10 and 24 months after treatment. Based on the results of this study and an earlier study on the effects of estrogen on BPH, it was concluded that MPA was a good alternative for treatment of canine BPH

    Congenital adrenal hyperplasia (CAH) is an autossomic recessive disorder caused by impaired steroidogenesis. Patients with CAH may present adrenal insufficiency with or without salt-wasting, as well as various degrees of virilization and fertility impairment, carrying a high incidence of testicular adrenal rest tumors and increased incidence of adrenal tumors. The diagnosis of CAH is made based on the adrenocortical profile hormonal evaluation and genotyping, in selected cases. Follow-up is mainly based on hormonal and clinical evaluation. Utility of imaging in this clinical setting may be helpful for the diagnosis, management, and follow-up of the patients, although recommendations according to most guidelines are weak when present. Thus, the authors aimed to conduct a narrative synthesis of how imaging can help in the management of patients with CAH, especially focused on genitography, ultrasonography, computed tomography, and magnetic resonance imaging.

    Unilateral condylar hyperplasia (UCH) is a disorder of unknown etiology mainly seen in growing patients, which results in facial asymmetry. High condylectomy alone or in association with orthognathic surgery can improve the occlusion and the facial aesthetics. Between 2005 and 2012, a total of 5 patients underwent high condylectomy for UCH using a piezoelectric cutting device. All patients were treated postoperatively with functional rehabilitation. The long-term follow-up showed that all patients had a satisfactory temporomandibular joint articular function associated with stable occlusion without any recurrence of further condylar growth. High condylectomy in the surgical treatment of unilateral UCH seems to be the procedure of choice in growing patients. The use of a piezoelectric cutting device allows a safe and less invasive high condylectomy.

    Congenital adrenal hyperplasia (CAH) is among the most common genetic disorders. Deficiency of adrenal steroid 21-hydroxylase deficiency due to mutations in the CYP21A2 gene accounts for about 95% cases of CAH. This disorder manifests with androgen excess with or without salt wasting. It also is a potentially life threatening disorder; neonatal screening with 17-hydroxyprogesterone measurement can diagnose the condition in asymptomatic children. Carefully monitored therapy with glucocorticoid and mineralocorticoid supplementation will ensure optimal growth and development for children with CAH. Genital surgery may be required for girls with CAH. Continued care is required for individuals with CAH as adults to prevent long-term adverse consequences of the disease, including infertility, metabolic syndrome and osteoporosis.

    2005-06-01

    Full Text Available Skeletal muscle hypertrophy is resulted from the individual increase of the fiber cross-sectional area. This adaptative phenomenon is normally observed in the muscle tissue submitted to a regimen of physical exercises, like strength training. The degree of muscular hypertrophy is directly related to the type of exercise and its intensity. Strength training normally produces a hypertrophy of greater magnitude when compared to other types of physical exercise. However, it is possible that there is another adaptive mechanism contributing for increasing skeletal muscle size. This mechanism is called hyperplasia, and can be defined as an increase in the cells, or fibers, number in the muscle. This brief review aims to verify the role of hyperplasia in the increase of skeletal muscle size. RESUMO A hipertrofia do músculo esquelético é resultado do aumento individual da área transversal da fibra. Este fenômeno adaptativo é comumente observado no tecido muscular submetido à um regime de exercícios físicos, como o treinamento de força. O grau de hipertrofia muscular está diretamente relacionado ao tipo de exercício e sua intensidade. O treinamento de força normalmente produz uma hipertrofia de maior magnitude, quando comparada aos outros tipos de exercício físico. Todavia, é provável que haja outro mecanismo adaptativo contribuindo para a hipertrofia do músculo esquelético. Este mecanismo chama-se hiperplasia, e pode ser traduzida por um aumento no número de células, ou fibras musculares em relação ao número original. Este breve resumo tem por objetivo verificar qual é o papel da hiperplasia na hipertrofia do músculo esquelético.

    Magnetic resonance imaging of pituitary hyperplasia has been rarely described in children with primary hypothyroidism. We report a case of pituitary hyperplasia in a child presented with significant growth arrest and laboratory evidence of hypothyroidism. Magnetic resonance imaging revealed symmetrical pituitary enlargement simulating macroadenoma. After thyroid hormone replacement therapy, the child's height increased and pituitary enlargement regressed to normal. Awareness of MRI appearance of pituitary hyperplasia in children with laboratory evidence of hypothyroidism might avoid misdiagnosis for pituitary tumor, which may also manifest as growth disorder, obviating unnecessary surgery.

    Mammary sclerosing lobular hyperplasia is an uncommon benign fibroproliferative lesion of adolescent and young women, often of African American heritage with an incidence of ~3%. Patients generally complain of a palpable, painless, or slightly tender and well-defined lump in breast. Very rarely, this lesion may be bilateral and diffuse. The definitive diagnosis of sclerosing lobular hyperplasia requires histopathologic evaluation. Here, we describe a case of diffuse sclerosing lobular hyperplasia in a 29-year-old African American woman that required bilateral mastectomy and recurred bilaterally requiring second resections. This appears to be the first report of this phenomenon.

    This paper reports a study of male nurses' experiences of providing intimate care for women clients. The number of men entering the nursing profession has increased worldwide. As a consequence of the move to a more gender-balanced profession, debate has ensued over how intimate care should be performed when this requires male nurses to be physically close to women clients. As there was little previous work on this topic, we wished to provide nurses, clients and other healthcare professionals with a better understanding of male nurses' experiences of working with women clients and within a healthcare system where they often feel excluded. Semi-structured, open-ended interviews were conducted with male nurses working in various clinical settings in Western Australia. Latent content analysis was used to analyse the interviews, which were carried out between June and July 2004. Three themes were identified: the definition of intimate care, the emotional experience associated with providing intimate care and strategies used to assist in the delivery of intimate care for women clients. Providing intimate care for women clients was a challenging experience for male nurses. Participants described how it required them to invade these clients' personal space. Consequently, they often experienced various negative feelings and used several strategies to assist them during care delivery. Nurse educators should assist male nurses to be better prepared to interact with women clients in various settings. Furthermore, workplace environments need to provide additional support and guidance for male nurses to enable them to develop effective coping strategies to manage challenging situations.

    One in 4 women is affected by intimate partner violence in her lifetime. This article reports on a cross-sectional survey to estimate community preferences for health states resulting from intimate partner violence. A secondary analysis was conducted of data from a convenience sample of 93 abused and 138 nonabused women (231 total) recruited for in-person interviews from hospital outpatient department waiting rooms in metropolitan Boston, Massachusetts. SF-12 data were converted to utilities to describe community-perspective preferences for health states associated with intimate partner violence. Linear regression analysis was used to explore the association between violence and utility while controlling for other health and demographic factors. Median utility for intimate partner violence was between 0.58 and 0.63 on a scale of 0 (equivalent to death) to 1.0 (equivalent to optimal health), with a range from 0.64 to 0.66 for less severe violence to 0.53 to 0.62 for more severe violence. The data do not reveal whether violence itself is responsible for lower utility or whether a constellation of factors contributes to disutility experienced by women victims of abuse. The utility of health states experienced by women exposed to intimate partner violence is substantially diminished compared with optimal health and even other health conditions. These values quantify the substantial negative health impact of the experience of intimate partner violence in terms that allow comparison across diseases. They can be used in cost-effectiveness analyses to identify the benefits and potential returns from resources allocated to violence prevention and intervention efforts.

    To identify pregnancy-associated homicide cases and to estimate the proportion that were perpetrated by a current or former intimate partner. This was an analysis of pregnancy-associated homicides occurring from 1993 to 2008 among Maryland residents using linked birth and death certificates, medical examiner charts, police records, and news publications. Homicides (n=110) were the leading cause of death during pregnancy and the first postpartum year. Women who were African American, younger than 25 years, and unmarried were at the highest risk for homicide. Firearms were the most common (61.8%) method of death. A current or former intimate partner was the perpetrator in 54.5% (n=60) of homicide deaths and a nonpartner in 31.8% (n=35). If the cases (n=15) in which the victim-offender relationship could not be identified are excluded, 63.2% of homicides were committed by an intimate partner. Compared with homicides in which the perpetrator was not an intimate partner, a significantly higher percentage (Phomicides occurred at home (66.7% compared with 28.6%), among women who had completed more than 12 years of education (23.3% compared with 5.7%), and who were married (28.3% compared with 8.6%). Intimate-partner homicides were most prevalent (25.0%) during the first 3 months of pregnancy and least prevalent during the first 3 months postpartum (5.0%). The majority of pregnancy-associated homicides were committed by current or former intimate partners, most commonly during the first 3 months of pregnancy. Efforts to protect women from partners optimally should begin before conception or very early in pregnancy. III.

    2012-01-01

    Full Text Available This article considers the ‘co-affective’ power of the new media artwork Intimate Transactions. This co-affective power operates at the ‘trans-subjective’ level of experience. In order to explore this level of experience the article draws on the work of Brian Massumi, Bracha Ettinger and Felix Guattari amongst others. For these thinkers the ‘trans-subjective’ level of experience, precisely because it is ‘co-affective’, holds ethical potential. The article argues for the importance of tending to ‘co-affective’ level of experience – both in designing “interactive” art, such as Intimate Transactions, and in life more generally.

    For an aim of more uniform child bulb production and good quality kind conservation using tissue culture of the lily, some hyperplasia from organs over ground of the lily were tried. In particular, optimum culture media with higher hyperplasia rate of the child bulb, redifferentiation due to difference among kinds of the lilies, and difference of hyperplasia of the child bulbs were investigated. As a result, it was found that pollution due to various germs attached to used materials often occurs, that efficiency obtainable for initial child bulb by redifferentiation from the organs was low at 20%, and that pollution due to various germs was often found at 25degC of cultivation temperature, which was inferior to that at 20degC. And, when conducting mass hyperplasia of the lily using tissue culture, an optimum culture medium of formation and hyperplasia of child bulb could be obtained for its each kind. As a result of conducting some investigations on configuration of the lily nourished from its child bulb and flowered by the tissue culture, it was also found that cultured bulb had the same character as its parent bulb had.

    Epithelial sheath neuroma is a rarely recognized but established entity in the medical literature. First described in 2000 by Requena et al, there have only been 7 published cases to date, mostly in female patients and presenting as symptomatic solitary lesions on the back without a known history of trauma. In 2006, Beer et al described and reviewed a dozen cases in which epithelial sheath neuroma-like features were seen in the advent of a surgical procedure, which was termed "re-excision perineural invasion" and attributed to possible eccrine duct implantation during surgery. Our case is a 66-year-old male patient who underwent an excision of a melanocytic neoplasm in which a reactive epithelial sheath neuroma was incidentally discovered in the excision specimen, adjacent to the biopsy site cicatrix. Histologically, there was benign cutaneous nerve hyperplasia with a proliferation of squamous epithelium in intimate apposition to the nerve bundles in the superficial dermis. We postulate that the process active in the formation of re-excision perineural invasion is the same as in epithelial sheath neuroma and that minor trauma not appreciable on histologic examination is responsible in the latter entity. We performed IL-6 staining and documented that IL-6 was upregulated at the interface of the nerve and reactive epithelium, but was absent in nerves distant from the site of surgery, suggesting that IL-6 may be essential to the lesion's development. The recognition of reactive epithelial sheath neuroma including the subcategory of re-excision perineural invasion is crucial for the dermatopathologist to prevent mislabeling this reactive entity as a perineural squamous cell carcinoma, which has clinical consequences for the patient such as wider re-excision and radiation treatment. Additionally, we have identified a potential pathophysiologic basis for this lesion.

    To investigate the effect of tranilast on wound healing and the mechanism of inhibiting scar hyperplasia in mice, and to study the relationship between the inhibiting ability of tranilast on scar hyperplasia and administration time. Sixty-six Kunming mice were selected to build deep II degree burn model, and were randomly divided into the control group (18 mice), the early intervention group (18 mice), the medium intervention group (18 mice), and the late intervention group (12 mice). The mice in the early intervention group, the medium-term intervention group, and the late intervention group were given tranilast 200 mg/(kg·d) by gastrogavage at immediate, 7 days, and 14 days after burn respectively, and the mice in the control group were managed with same amount of normal saline every day. The wound healing was observed regularly. At 14, 28, and 42 days in the early and medium intervention groups and at 28 and 42 days in the late intervention group, fresh tissues were taken from 6 mice to observe the shape of mast cells by toluidine blue staining, collagen content by Masson staining; the collagen type I and collagen type III content were measured to calculate the I/III collagen content ratio by immunohistochemistry method, the contents of transforming growth factor β 1 (TGF-β 1 ) and histamine were detected by ELISA; and the ultrastructure of fibroblasts was observed under transmission electron microscope. There was no significant difference in wound healing time between groups ( F =1.105, P =0.371). The mast cells number, collagen content, TGF-β 1 content, histamine content, and the I/III collagen content ratio in the early intervention group were significantly less than those in the other groups ( P 0.05). Compared with the control group, the activity of fibroblasts in the early intervention group was obviously inhibited, and the arrangement of the fibers was more regular; the fibroblast activity in the medium and late intervention groups was also inhibited

    Abstract Background Violence against women, especially by intimate partners, is a serious public health problem that is associated with physical, reproductive and mental health consequences. Even though most societies proscribe violence against women, the reality is that violations against women's rights are often sanctioned under the garb of cultural practices and norms, or through misinterpretation of religious tenets. Methods We utilised data from 17 Demographic and Health Surveys (DHS) co...

  5. Unilateral Bimaxillary Idiopathic Fibrous Gingival Hyperplasia with Alveolar Bone Loss- Report of a Rare Case

    Full Text Available Gingival enlargements are of many types and vary according to the etiologic factors and pathologic processes that produce them. Though there are many classifications of gingival enlargement, the most practical one is as follows: 1 Inflammatory gingival enlargement 2 Fibrous gingival hyperplasia 3 Combination of inflammatory and fibrous hyperplasia. Gingival hyperplasia is a heterogeneous group of disorder, which appears clinically as diffuse, firm, and massive enlargement of the gingiva covering most of the crown of the teeth. Idiopathic gingival enlargement is a rare condition of undetermined etiology, although some cases have definite hereditary basis. A case of unilateral idiopathic fibrous gingival hyperplasia on left side of both the jaws with severe bone resorption is presented.

    Lepidium meyenii (maca) is a plant that grows exclusively above 4000 m in the Peruvian central Andes. Red maca (RM) extract significantly reduced prostate size in rats with benign prostatic hyperplasia (BPH) induced by testosterone enanthate (TE). Zinc is an important regulator of prostate function. This study aimed to determine the effect of RM on prostate zinc levels in rats with BPH induced by TE. Also, the study attempted to determine the best marker for the effect of RM on sex accessory glands. Rats treated with RM extract from day 1 to day 14 reversed the effect of TE administration on prostate weight and zinc levels. However, RM administered from day 7 to day 14 did not reduce the effect of TE on all studied variables. Finasteride (FN) reduced prostate, seminal vesicle and preputial gland weights in rats treated with TE. Although RM and FN reduced prostate zinc levels, the greatest effect was observed in TE-treated rats with RM from day 1 to day 14. In addition, prostate weight and zinc levels showed the higher diagnosis values than preputial and seminal vesicle weights. In conclusion, RM administered from day 1 to day 14 reduced prostate size and zinc levels in rats where prostatic hyperplasia was induced with TE. Also, this experimental model could be used as accurately assay to determine the effect of maca obtained under different conditions and/or the effect of different products based on maca. © 2011 Blackwell Verlag GmbH.

  8. Congenital Adrenal Hyperplasia in an Elite Female Soccer Player; What Sports Medicine Clinicians Should Know about This?

    2012-09-01

    Congenital Adrenal Hyperplasia (CAH) refers to a group of congenital conditions characterized by disordered cortisol synthesis. The correlation between CAH and sports performance has been less studied before and there is very limited information regarding the impacts of this congenital disease on sports performance. Probably, there are some limitations for patients who suffer from CAH in sports, but at the same time, they may enjoy some advantage due to the probable effect of endogenous hyperandrogenism on their exercise performance. The case is a 14 - year old girl with male phenotype who is a known case of congenital adrenal hyperplasia. She plays in the women's national soccer team of under 16. She has been in the first division league of indoor soccer for 4 years and was also selected in the preparation training camp of women's football team for Singapore's youth Olympic Games. Her illness and dependence on corticosteroid have caused some concerns for her participation in the international competitions of women. However, following consultations with the Therapeutic Use Exemption (TUE) Committee of games organization, she received TUE to use corticosteroid only within the games period. Despite all her problems, she is now playing in the Second Division League of indoor soccer. A female adolescent with CAH may compete at the high level of outdoor and indoor soccer. However, there are many questions regarding the advantages and disadvantages of this congenital disorder and its treatment on sports related issues.

    2011-02-01

    Hidradenitis suppurativa/acne inversa is a chronic, inflammatory, scarring disease in the terminal hair follicle and apocrine gland-bearing areas (skin folds). There is considerable histological evidence that perifolliculitis and follicular hyperkeratosis precede the rupture of the follicle. The timing of the epithelial hyperplasia at the infundibula of inflamed terminal follicles has not yet been clarified. To clarify the early histopathological life of lesions ('chronology') in hidradenitis suppurativa/acne inversa, focusing on the terminal follicle structure and its surrounding tissue (hyperkeratosis, hyperplasia of follicular epithelium, perifolliculitis and rupture). In total, 485 operative specimens obtained from 128 patients with diagnosed hidradenitis suppurativa/acne inversa (all surgically treated by wide excision) were examined histologically. Two to five histological preparations (total 485) per operation area (total 196) were prepared by multiple slicing. Hidradenitis suppurativa/acne inversa showed a heterogeneous histological pattern: hyperkeratosis of the terminal follicles (89%), hyperplasia of follicular epithelium (80%), pronounced perifolliculitis (68%) and follicle rupture (24%). Perifolliculitis, follicular hyperkeratosis and hyperplasia occurred prior to the rupture of the follicle. Other histological criteria were: subepidermal cellular inflammatory infiltrate (82%), epidermal psoriasiform hyperplasia (56%), pronounced acute dermal inflammation (28%), pronounced chronic dermal inflammation (49%), and involvement of apocrine glands (52%) and subcutis (31%). Infundibular hyperkeratosis, hyperplasia of the follicular epithelium and perifolliculitis are major histopathological characteristics of hidradenitis suppurativa/acne inversa. These apparently precede rupture of the follicle. In particular, hyperplasia of the follicular epithelium probably marks the beginning of sinus formation, which usually spreads horizontally.

    Thyroid carcinogenesis is traditionally thought to originate 'de novo'. However, it is debatable whether a malignant transformation can possibly arise from a benign thyroid nodule, as suggested for the malignant transformation of a thyroid adenoma. To the best of our knowledge, no studies have been performed addressing the malignant transformation of nodular hyperplasia in the thyroid gland. Here, we report a case of nodular hyperplasia with focally malignant degeneration

    Pituitary hyperplasia is generally associated with end-organ failure such as primary hypothyroidism, physiological changes such as puberty and pregnancy, or neoplasms secreting releasing factors. We present a full-term infant with an enlarged pituitary height of 8 mm at age 3 days despite a normal endocrinological evaluation. Repeat imaging at 5 months of age revealed a normal-size pituitary gland. To our knowledge, pituitary hyperplasia has not been described in a neonate with normal pituitary function. (orig.)

    2001-01-01

    Intimate partner violence not only affects adults but also the children living within that "war zone." The present study expands our understanding about how children are affected when they observe violence in their own homes, as reported by their mothers. This descriptive study was conducted to describe mothers' perspectives of the impact of the violence on their children. A consecutive sample of 72 mothers attempting to file assault charges were interviewed in a private room by a registered nurse and were asked to describe the effect of witnessing intimate partner violence on their child's behavior. Each response was written verbatim by the interviewer. A majority (72%) of the mothers reported negative behaviors in their children that they believed were as a result of witnessing their mother's violent experiences. The most common negative traits were distress-indicating behaviors such as sleep disturbances, clinging, and fretful behaviors followed by problems with the abuser, problems in school, and problems with mother. Because intimate partner violence affects children, health care providers should become familiar with behaviors indicative of this problem. To promote the well being and development of children, recommendations for assessment and intervention for women experiencing intimate partner violence are discussed.

    Introduction The aim of the present cross-sectional study was to investigate the prevalence of intimate partner physical violence among depressive Turkish women, as well as the association of intimate partner physical violence with attachment patterns, childhood traumas, and socio-demographic factors. Methods The study included 100 women diagnosed with depressive disorder and 30 healthy women. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-IV axis I disorders, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Adult Attachment Style Questionnaire (AASQ), and Childhood Trauma Questionnaire (CTQ) were used for clinical assessment. Results It was found that 64% of the women diagnosed with depression were suffering from intimate partner physical violence. In these women, the severity of depression and anxiety symptoms was higher, suicidal ideation and suicide attempts were more common, and the diagnosis of double depression was more prevalent. These women also achieved higher scores in the avoidant and ambivalent subscales of AASQ and higher total scores and higher scores in the physical abuse subscale of CTQ. The partner’s and the woman’s experiences of physical violence in their families during their childhood predicted intimate partner physical violence for women suffering from depression. Conclusion The investigation of domestic violence contributes to the treatment of depression and also to the recognition and prevention of domestic violence that has profound effects on successive generations.

    To apply massage therapy accompanied with stretching exercises for treatment of mammary gland hyperplasia, evaluate the clinical outcome in patients, and estimate the therapy as a novel treatment method for mammary hyperplasia. 28 adult female patients were selected and treated with massage therapy and stretching exercises focusing on skeleton muscles of chest, abdomen, and axilla. The mammary gland oxyhemoglobin (OxyHb) and deoxyhemoglobin (DeoxyHb) levels were detected before and after treatment after 15, 30, and 45 days. In this cohort, pretreatment OxyHb (mean ± SD) is 1.32 ± 0.14 (medium-high), and DeoxyHb is 0.87 ± 0.13 (normal). All patients were clinically diagnosed with benign mammary gland hyperplasia and mastitis. The posttreatment OxyHb levels are 1.23 ± 0.09 (normal-medium, 15-day), 1.16 ± 0.08 (normal, 30-day), and 1.05 ± 0.04 (normal, 45-day), and DeoxyHb levels are 0.90 ± 0.11 (normal, 15-day), 0.94 ± 0.18 (normal, 30-day), and 0.98 ± 0.12 (normal, 45-day). Patients were diagnosed with decreased hyperplasia 15 and 30 days after treatment and with no symptom of hyperplasia in mammary gland 45 days after treatment. Mammary gland hyperplasia is closely correlated with pathological changes of skeletal muscles and could be significantly improved by massage therapy and stretching exercises targeting neighboring skeletal muscles.

    The study was to assess the usefulness of T2-weighted and enhanced T1-weighted MR images in differentiating endometrial adenocarcinoma and hyperplasia. The subjects were 21 patients with endometrial hyperplasia (Group A), consisting of 15 with cystic glandular hyperplasia and 6 with atypical hyperplasia, and 7 with endometrial adenocarcinoma (Group B). Six other patients with no evidence of abnormal endometrial findings served as controls. In Group A, the endometrium had a high signal intensity on T2-weighted images, and was 10 mm or over in thickness before menopause and 6 mm after menopause. It was also a high or intermediate signal intensity on enhanced T1-weighted images. In patiemts with cystic glandular hyperplasia, the junctional zone was 10 mm or over on T2-weighted images. Similar findings were seen on enhanced T1-weighted images. In patients with atypical hyperplasia, the junctional zone disappeared or decreased on enhanced images compared with those on T2-weighted images. In group B, the endometrium had an intermediate or high signal intensity on T2-weighted images, with the junctional zone being 10 mm or more. Enhanced T1-weighted images showed lower signal intensities in the tumorous area than in the normal endometrium and muscular layer. These findings indicated that enhanced MR imaging may be useful in diagnosing endometrial lesions. (N.K.).

    Marcela Franklin Salvador de Mendonça

    Full Text Available ABSTRACT OBJECTIVE To investigate the association of intimate partner violence against women reported in the last 12 months and seven years with the incidence of common mental disorders. METHODS A prospective cohort study with 390 women from 18 to 49 years, registered in the Family Health Program of the city of Recife, State of Pernambuco; from July 2013 to December 2014. The Self Reporting Questionnaire-20 (SRQ-20 assessed mental health. Intimate partner violence consists of concrete acts of psychological, physical or sexual violence that the partner inflicts on the woman. Poisson regression was used to estimate crude and adjusted relative risks (RR of the association between common mental disorders and intimate partner violence. RESULTS The incidence of common mental disorders was 44.6% among women who reported intimate partner violence in the last 12 months and 43.4% among those who reported in the past seven years. Mental disorders remained associated with psychological violence (RR = 3.0; 95%CI 1.9–4.7 and RR = 1.8; 95%CI 1.0–3.7 in the last 12 months, and seven years, respectively, even in the absence of physical or sexual violence. When psychological violence were related to physical or sexual violence, the risk of common mental disorders was even higher, both in the last 12 months (RR = 3.1; 95%CI 2.1–4.7 and in the last seven years (RR = 2.5; 95%CI 1.7–3.8. CONCLUSIONS Intimate partner violence is associated with the incidence of common mental disorders in women. The treatment of the consequences of IPV and support for women in seeking protection for themselves for public services is essential.

    2017-08-01

    In this qualitative study, we explored women's pregnancy intentions and experiences of intimate partner violence before, during and after pregnancy. Unintended pregnancies in the context of intimate partner violence can have serious health, social and economic consequences for women and their children. Feminist and phenomenological philosophies underpinned the study to gain a richer understanding of women's experiences. Eleven women who had been pregnant in the previous two years were recruited from community-based women's refuges in one region of the UK. Of the 11 women, eight had unplanned pregnancies, two reported being coerced into early motherhood, and only one woman had purposively planned her pregnancy. Multiple in-depth interviews focused on participants' accounts of living with intimate partner violence. Experiential data analysis was used to identify, analyse and highlight themes. Three major themes were identified: men's control of contraception, partner's indiscriminate response to the pregnancy and women's mixed feelings about the pregnancy. Participants reported limited influence over their sexual relationship and birth control. Feelings of vulnerability about themselves and fear for their unborn babies' safety were intensified by their partners' continued violence during pregnancy. Women experiencing intimate partner violence were more likely to have an unintended pregnancy. This could be attributed to male dominance and fear, which impacts on a woman's ability to manage her birth control options. The women's initial excitement about their pregnancy diminished in the face of uncertainty and ongoing violence within their relationship. Women experiencing violence lack choice in relation to birth control options leading to unintended pregnancies. Interpreting the findings from the victim-perpetrator interactive spin theory of intimate partner violence provides a possible framework for midwives and nurses to better understand and respond to women

  6. School bullying perpetration and other childhood risk factors as predictors of adult intimate partner violence perpetration.

    To assess the relationship between bullying peers as a child and adult intimate partner violence perpetration in a clinic-based sample of adult men. School bullying perpetration and intimate partner violence perpetration are both thought to stem from desire for power and control over others. A cross-sectional survey was conducted between January 2005 and December 2006. Three urban community health centers in Boston, Massachusetts. Men aged 18 to 35 years (n = 1491) seeking services at participating community health centers. School bullying perpetration. Past-year physical or sexual violence perpetration against a female partner (intimate-partner violence [IPV]). Two-fifths of men reported perpetrating school bullying as a child (n = 610; 40.9%). Men who rarely bullied in school were 1.53 times more likely to perpetrate past-year IPV than men who did not bully (95% confidence interval [CI], 1.02-2.29); this risk was elevated to 3.82 times more likely to perpetrate any past-year IPV for those men who bullied peers frequently (95% CI, 2.55-5.73). The present study indicates that bullying peers in school as a child, especially frequent bullying perpetration, is associated with increased risk for men's perpetration of IPV as an adult. The effect remains strong after controlling for common prior risk factors for both bullying and IPV perpetration. Future research is needed to discern the mechanisms and underlying root causes of abusive behavior, such as power and control, as a means to prevent violence perpetration across settings and life stages.

  7. CHALLENGING SEXUAL PATTERNS OF NORMALITY IN THE XIX CENTURY: THE INTIMATE DIARY OF JOSÉ VIEIRA COUTO DE MAGALHÃES (1880-1887

    Full Text Available This article aims at analyzing the intimate diary of José Vieira Couto de Magalhães, a XIX century politician and thinker. The diary under analysis was written between 1880 and 1887. The author’s intimate writing encompasses a multitude of issues, including his disregard for women, his fears, anguish, business, his personal and intimate relationships, concerns as to caring for the body, and, in particular – and of special interest for this article – a feverish sexuality which is expressed in dreams, revealing a strong homoerotic desire. Living in a period in which homosexuals were badly regarded by society, were considered “propagators of sin”, by the Church, and as carriers of “sexual instinct” diseases in medical discourse, José Vieira described his erotic dreams with partners of the same sex in a natural and spontaneous manner, without attributing any negative labelling to these dreams.

    Multifocal epithelial hyperplasia (MEH), also known as Heck’s disease, manifests as a papulonodular lesion in the oral mucosa and has been associated with the human papillomavirus, a virus related to various precancerous diseases in the oral cavity. It has a predisposition for the female gender and for children. Although the majority of reported cases have been among American Indians and Eskimos, it has been described in multiple ethnic groups in various geographical locations. The objective of this review was to report on the clinical characteristics and epidemiology of MEH and its possible correlation with oral cancer. It is based on a search of articles in international journals published prior to April 2011, using the PubMed database and selecting articles related to the epidemiology and clinical characteristics of MEH. The review revealed a higher number of cases in individuals of American Indian origin and a predilection of the disease for the female gender and for patients between the 1st and 2nd decades of life. The most frequent lesion site was the lower lip. The disease has been associated with socio-economic and genetic factors, among others. No cases of malignant transformation have been reported.

    Stenosis of arteriovenous (A-V) fistulae secondary to neointimal hyperplasia (NIH) compromises dialysis delivery, which worsens patients' quality of life and increases medical costs associated with the maintenance of vascular accesses. In the present study, we evaluated the role of the receptor tyrosine kinase c-Kit in A-V fistula neointima formation. Initially, c-Kit was found in the neointima and adventitia of human brachiobasilic fistulae, whereas it was barely detectable in control veins harvested at the time of access creation. Using the rat A-V fistula model to study venous vascular remodeling, we analyzed the spatial and temporal pattern of c-Kit expression in the fistula wall. Interestingly, c-Kit immunoreactivity increased with time after anastomosis, which concurred with the accumulation of cells in the venous intima. In addition, c-Kit expression in A-V fistulae was positively altered by chronic kidney failure conditions. Both blockade of c-Kit with imatinib mesylate (Gleevec) and inhibition of stem cell factor production with a specific short hairpin RNA prevented NIH in the outflow vein of experimental fistulae. In agreement with these data, impaired c-Kit activity compromised the development of NIH in A-V fistulae created in c-KitW/Wv mutant mice. These results suggest that targeting of the c-Kit signaling pathway may be an effective approach to prevent postoperative NIH in A-V fistulae. PMID:25186298

    We evaluated the pattern of baldness and serum androgen levels in patients with benign prostate hyperplasia (BPH) and prostate cancer. BPH, prostate cancer and androgenic alopecia (AA) were somehow androgen dependent and affect large population of elderly men. A total of 152 patients, 108 patients with BPH and 44 patients with prostate cancer were included in the study. We measured serum total, free and bioavailable testosterone, FSH, LH, prolactin, estradiol, albumin and SHBG levels. Baldness classification was based on Norwood's classification and we categorised baldness as vertex and frontal baldness. The frequency of AA in BPH and prostate cancer groups were not different. We looked for some correlation between the two groups with respect to AA and hormone levels. We did not find any correlation between AA and total testosterone, free testosterone, bioavailable testosterone or SHBG levels in both groups. This prospective study with selected small group of patients showed that there is no difference of male pattern baldness in BPH and prostate cancer patients and also there is no correlation between pattern of baldness and serum androgen levels.

    To assess the epidemiology of benign prostatic hyperplasia (BPH) in a case-control study in greater Athens, Greece. The study comprised 184 patients surgically treated for BPH within one year of its diagnosis (cases) and 246 patients with no symptoms of BPH who were treated in the same hospitals for minor diseases or conditions (controls). All cases and controls were permanent residents of the greater Athens area, Greece. The data were assessed using unconditional logistic regression. After controlling for age and education, cases and controls had similar distributions for height, body mass index, sibship size and birth order in the parental family, marital status, number of offspring and a series of previous medical diagnoses or surgical operations. The sole exception was surgery for haemorrhoids, that appeared to be related to the incidence of BPH, possibly by chance. There was no evidence that vertex baldness, tobacco smoking, alcohol consumption or coffee drinking increased the risk for BPH. Men who had spent most of their lives in a rural rather than an urban environment appeared to be at reduced risk for BPH. The lifestyle factors assessed here have no major effect on the aetiology of BPH.

  12. Bilateral coronoid hyperplasia causing painless limitation of mandibular movement

    2018-02-01

    Full Text Available The coronoid process is a beaklike process in the ramus of the mandible. Coronoid process hyperplasia (CPH is a rare possible cause of reduced mouth opening. An overgrown process interferes with mandibular rotation and lateral excursion and hence leads to restricted mouth opening (RMO. Although some factors are suggested, etiology of CPH is not completely known. Prescription of suitable radiography is necessary for an accurate diagnosis. This article reports a 30-year-old man with bilateral CPH and progressive RMO since childhood. This disorder affected his oral hygiene and quality of life. With the help of different types of radiography, CPH was diagnosed and coronoidectomy was the only treatment option. The patient showed normal jaw movements after the surgery and postoperative physiotherapy. General dentists have an important role in noticing RMO and referring the patients to maxillofacial radiologists. Although it is a rare phenomenon, general dentists need to keep CPH in mind as a possible cause. Panoramic imaging accompanied by computed tomography or cone beam computed tomography is the best imaging option in such cases.

    Objective: To assess the diagnostic value of MRI on multiple focal nodular hyperplasia (FNH) of the liver. Methods: MR images of 9 cases with pathological-confirmed multiple FNH were retrospectively analyzed. MRI features of the lesions were correlated with pathological findings. Results: Multiple FNH was considered in all these 9 cases. Among them, the primary diagnosis was FNH in 5, hepatic adenoma in 3 and fibrolamellar hepatocellular carcinoma in 1 case. A total of 31 lesions were detected in the 9 cases. On T 2 WI, 19 lesions presented slightly high-signal intensity, and the other 12 presented iso-signal intensity. On T 1 WI, 12 lesions presented slightly low-signal intensity, 7 presented iso-signal intensity, and the other 12 presented high-signal intensity. On opposed-phase, the signal intensity of 1 lesion dropped unevenly. After bolus injection of contrast agent Gd-DTPA, in hepatic arterial phase 18 lesions showed mild to marked heterogeneous enhancement, 11 showed marked homogeneous enhancement, 1 showed moderate ring-like enhancement, and the last one did not have obvious enhancement. In portal venous and delayed phase, all the lesions turned to iso- or slightly high-signal intensity gradually. Sixteen of 31 lesions presented central scar, which demonstrated mild star-like enhancement in delayed phase. Conclusion: Multiple FNH presented certain MRI features, which contributed to the preoperative diagnosis. (authors)

    Objective: To evaluate the MSCT findings of focal nodular hyperplasia (FNH) of the liver, and to improve the diagnostic standard. Methods: The MSCT findings were analyzed retrospectively in 25 patients pathologically approved with FNH. All patients underwent 16 detector row spiral CT scanning with and without contrast enhancement. Results: 28 lesions were discovered by CT, with single lesion showed in 22 cases, 2 lesions showed in 3 cases. All lesions showed a solitary nodules or lobulated mass in the liver. On plain CT, FNH showed equal or slightly low density. In the arterial phase, 27 lesions were vigorously and homogeneously enhanced, except the central scars with CT value of 99∼149HU and the mean CT-number of 124 HU. 1 lesion ws enhanced inter-homogeneously. Tortuous and enlarged arteries were seen at the center or periphery in 8 of the 28 lesions. In the portal venous phase, 16 lesions remained slightly hyperdense, 8 lesions turned to isodense, and 1 lesion turned to slightly hypodense. The typical central scar was showed in 8 lesions and 2 lesions showed delayed enhancement. 21 cases were correctly diagnosed by MSCT, with the diagnostic accuracy of 84.0%. Conclusion: MSCT scanning can fully show the pathologic and the blood supplying characteristics of FNH. The typical FNH can be easily diagnosed by CT, while the atypical cases should be differentiated from hepatocellular carcinoma, hemangioma of liver, liver cell adenoma and fibrolamellar hepatocarcinoma.

    Focal nodular hyperplasia of the liver (FNH) is a histologically defined benign hepatic tumour, possibly associated with the use of oral contraceptives. The present study deals with the question whether FNH can be distinguished from other lesions of the liver by ultrasonography alone or by a combination of realtime sonography and radiologic procedures. Therefore 18 cases of FNH, 16 females and 2 males, are presented. We retrospectively reviewed the diagnostic results of real-time sonography, hepatic scintigraphy, computed tomography with dynamic CT-densitometry, and angiography on these 18 patients. Ultrasonography enables the identification of the lesion in all of the 18 cases. FNH appears to show varying degrees of echogenicity (slight hypoechoic in 6 cases, isoechoic in 6 cases, and slight hyperechoic in 4 cases). In most of the patients the tumour had similar acoustic characteristics at the surrounding normal liver. By ultrasonography alone there is no possible differentation of FNH from other hepatic tumours. Both the echo pattern of FNH and the results of the ultrasonically guided cytopuncture are unspecific.

    Full Text Available Background: The purpose of observational program of patients with lower urinary tract symptoms (LUTS because of benign prostatic hyperplasia (BPH (LUTS/BPH was to acquire additional pharmaco-epidemiological data on the safety and efficacy of combination therapy with finasteride and tamsulosin.Methods: Observational program of men with BPH was conducted in urological outpatient clinics in Slovenia from April 2004 until November 2005. In open-label, non-interventional program 1173 patients were observed, who had been treated because of LUTS/BPH with combination therapy with finasteride and tamsulosin, in the framework of common treatment. At baseline and after six months of treatment for each patient the International Prostatic Symptom Score (IPSS questionnaire and assessment of quality of life (QL were filled in. In addition, urinary flow rate and prostate volume were determined. Adverse effects of drugs were reported spontaneously. For statistical analysis the Student’s t-test was performed.Results: Combination therapy with finasteride and tamsulosin was well tolerated. 89 (7.6 % patients discontinued with medication because of lack of efficacy or because of adverse effects of drugs. Symptom score, assessment of quality of patients’ lives and volume of prostates were significantly lower (p < 0.0001, while urinary flow rate was significantly higher (p < 0.0001 after six months of treatment with finasteride and tamsulosin.Conclusions: Combination therapy of patients with LUTS/BPH with finasteride and tamsulosin is effective and safe.

    Benign prostate hyperplasia (BPH) occurs in up to 50% of men by age 50, and the incidence increases with age. This common clinical problem is diagnosed by history, including the International Prostate Symptom Score (IPSS) questionnaire, and physical examination by digital rectal examination (DRE). Initial management for BPH includes lifestyle modification, and smooth muscle relaxant alpha blocker therapy. Alpha blockers usually take effect quickly within 3-5 days, and have minimal side effects. Current commonly used alpha blockers include the selective alpha blockers tamsulosin (Flomax), alfusosin (Xatral), and silodosin (Rapaflo). For patients with larger prostates, the 5-alpha reductase inhibitor class (finasteride (Proscar) and dutasteride (Avodart)) work effectively to shrink prostate stroma resulting in improved voiding. The 5-ARI class of drugs, in addition to reducing prostate size, also reduce the need for future BPH-related surgery, and reduce the risk of future urinary retention. Drugs from the phosphodiesterase-5 (PDE-5) inhibitor class may now be considered for treating BPH. Once daily 5 mg tadalafil has been shown to improve BPH-related symptoms and is currently approved to treat patients with BPH. Referral to a urologist can be considered for patients with a rising prostate-specific antigen (PSA), especially while on 5-ARI, failure of urinary symptom control despite maximal medical therapy, suspicion of prostate cancer, hematuria, recurrent urinary infections, urinary retention, or renal failure. Currently the primary care physician is armed with multiple treatment options to effectively treat men with symptomatic BPH.

    Full Text Available Fibronectin (FN is a multifunctional glycoprotein involved in cell-matrix interactions. It exhibits a complex pattern of forms differing in respect to aminoacid and oligosaccharide composition. In this study we examined glycobiochemical and functional properties of the FN in benign prostatic hyperplasia (BPH and prostatic cancer (PCa, attempting to resolve disease-related differences. Two BPH sera pools and three PCa sera pools were used as the FN source. The affinity-purified molecule was characterized by SDS-PAGE, immuno- and lectin blot, lectin-affinity chromatography and adhesion assay. BPH FN existed as intact molecule, giving the main immunoreactive band at 220 kDa. In contrast, PCa FN comprised three main immunoreactive fragments of 140, 110 and 90 kDa. As for glycosylation the ratio of altogether lectin-reactive PCa FN was different from that of BPH FN manifested as a decrease of Con A- and an increase of LCA-reactive moieties. Fibroblasts adhered to both FN preparations in a concentration dependent manner, but with a significantly lower efficiency to PCa FN. The results obtained showing distinct structural characteristics of PCa FN compared to BPH FN could be important for modulation of its ligand and recognition properties expressed as gain or loss of functions or as specific markers of its origin.

  19. Nonclassic congenital adrenal hyperplasia misdiagnosed as Turner syndrome

    Full Text Available We present a patient with nonclassic congenital adrenal hyperplasia (NCAH misdiagnosed as mosaic Turner syndrome. She presented with complaints of primary infertility. Short stature, the presence of facial hair and hoarse voice was also noted. She had primary amenorrhea and was advised for karyotype at 16 years of age, which was reported as 45, X[20]/46, XX[80], stating her as a case of mosaic Turner syndrome. Clitoroplasty was done at 21 years of age for clitoromegaly, which was noticed during puberty. The diagnosis of mosaic Turner could not explain the virilization. Therefore, we repeated the karyotype, which revealed 46, XX in more than 100 metaphases and was sufficient to exclude mosaicism. Furthermore, the endocrinological evaluation revealed high testosterone level with a normal 17 alpha-hydroxyprogesterone (17-OHP. The presence of pubertal onset virilization with a karyotype of 46, XX and raised testosterone level with normal 17-OHP level, raised the suspicion of NCAH for which adrenocorticotropic hormone stimulation test was done which confirmed the diagnosis of NCAH.

    Full Text Available Psychological outcomes in persons with congenital adrenal hyperplasia (CAH have received substantial attention. The objectives of this paper were to (1 catalog psychological endpoints assessed in CAH outcome studies and (2 classify the conceptual/theoretical model shaping the research design and interpretation of CAH-related psychological effects. A total of 98 original research studies, published between 1955 and 2009, were categorized based on psychological endpoints examined as well as the research design and conceptual model guiding analysis and interpretation of data. The majority of studies (68% investigated endpoints related to psychosexual differentiation. The preponderance of studies (76% examined a direct relationship (i.e., inferring causality between prenatal androgen exposure and psychological outcomes. Findings are discussed in relation to the observed imbalance between theoretical interest in the role of prenatal androgens in shaping psychosexual differentiation and a broader conceptual model that examines the role of other potential factors in mediating or moderating the influence of CAH pathophysiology on psychological outcomes in both affected females and males. The latter approach offers to identify factors amenable to clinical intervention that enhance both health and quality of life outcomes in CAH as well as other disorders of sex development.

    Multifocal adenomatous oncocytic hyperplasia (MAOH) is a non-neoplastic lesion that is classified as oncocytosis. MAOH is a rare entity of the parotid gland and accounts for approximately 0.1% of salivary gland lesions. Here, we report a case of MAOH of the parotid gland. The patient was a 71-year-old woman who presented with discomfort at the left side of her neck. Fine-needle aspiration cytology of the parotid gland revealed a loose sheet-like cluster of round to polygonal cells with granular cytoplasm against a hemorrhagic background. The cells had round to oval, centrally located nuclei with granular chromatin and without distinct nucleoli. Histologically, the lesion was formed of many variable-sized nodules, comprising oncocyte-like cells with small round nuclei and eosinophilic granular cytoplasm that was positive for mitochondrial antibodies. The diagnosis of MAOH is difficult to make by cytology alone, because the findings overlap with those of other oncocytic lesions. In particular, the cytological findings of MAOH have not been sufficiently reported to date. A correlation of cytology and histology was expected. PMID:25580104

    Pandolfo III Malatesta (1370-1427) was a leading figure of the Italian Renaissance. He was a valiant soldier and horseman with a very active life style. Historical sources report that he died of a fever in 1427. The tomb, containing his mummified body, has recently been discovered in Fano (Marche, Central Italy). After careful X-ray and videographic examination, autopsy was performed to diagnose possible pathologies. Samples of different tissues were collected and rehydrated by Sandison's method and submitted to routine histology processes. Sections of treated tissue were fixed on clean slides, stained with hematoxylin-eosin or Gardner's Trichromic and observed at light microscope. RESULTS AND CONCLUSIONS The autopsy showed good preservation of the skeletal muscles, cartilage, internal and external organs included prostate gland and penis. Macroscopic examination revealed stag-horn calculi (calcium urate) of the left kidney and a severe enlargement of the prostate, with calcifications detectable by X-ray and a large nodule protruding in the lumen of an ectatic urethra. Histology shows fibrous bands of connective and muscular tissue surrounding some circular and oblong lacunae, with no preservation of epithelial structures. The macroscopic and histological picture, showing clear prostatic nodular hyperplasia, makes this the first case described in paleopathology. Copyright 2000 Wiley-Liss, Inc.

    Full Text Available Background. Papillary thyroid carcinoma (PTC, follicular thyroid adenoma (FTA, and thyroid nodular hyperplasia (TNH are the most frequent diseases of the thyroid gland. Previous studies described the involvement of dipeptidyl-peptidase IV (DPPIV/CD26 in the development of thyroid neoplasia and proposed it as an additional tool in the diagnosis/prognosis of these diseases. However, very little is known about the involvement of other peptidases in neoplastic and hyperplastic processes of this gland. Methods. The catalytic activity of 10 peptidases in a series of 30 PTC, 10 FTA, and 14 TNH was measured fluorimetrically in tumour and nontumour adjacent tissues. Results. The activity of DPPIV/CD26 was markedly higher in PTC than in FTA, TNH, and nontumour tissues. Aspartyl aminopeptidase (AspAP, alanyl aminopeptidase (AlaAP, prolyl endopeptidase, pyroglutamyl peptidase I, and aminopeptidase B activities were significantly increased in thyroid neoplasms when compared to nontumour tissues. AspAP and AlaAP activities were also significantly higher in PTC than in FTA and TNH. Conclusions. These data suggest the involvement of DPPIV/CD26 and some cytosolic peptidases in the neoplastic development of PTC and FTA. Further studies will help to define the possible clinical usefulness of AlaAP and AspAP in the diagnosis/prognosis of thyroid neoplasms.

    Full Text Available PURPOSE: Objective quantifications of facial asymmetry in patients with Unilateral Condylar Hyperplasia (UCH have not yet been described in literature. The aim of this study was to objectively quantify soft-tissue asymmetry in patients with UCH and to compare the findings with a control group using a new method. MATERIAL AND METHODS: Thirty 3D photographs of patients diagnosed with UCH were compared with 30 3D photographs of healthy controls. As UCH presents particularly in the mandible, a new method was used to isolate the lower part of the face to evaluate asymmetry of this part separately. The new method was validated by two observers using 3D photographs of five patients and five controls. RESULTS: A significant difference (0.79 mm between patients and controls whole face asymmetry was found. Intra- and inter-observer differences of 0.011 mm (-0.034-0.011 and 0.017 mm (-0.007-0.042 respectively were found. These differences are irrelevant in clinical practice. CONCLUSION: After objective quantification, a significant difference was identified in soft-tissue asymmetry between patients with UCH and controls. The method used to isolate mandibular asymmetry was found to be valid and a suitable tool to evaluate facial asymmetry.

    Full Text Available Metabolic syndrome (MetS is a cluster of metabolic abnormalities related to central adiposity and insulin resistance. Its importance is increasingly recognized as it associates with increased risks of metabolic and cardiovascular diseases. These metabolic aberrations of MetS may lead to development of benign prostatic hyperplasia (BPH and lower urinary tract symptoms (LUTS in men. A 26.5%–55.6% prevalence of MetS in men with LUTS was reported in worldwide studies. Although the exact biological pathway is not clear yet, insulin resistance, increased visceral adiposity, sex hormone alterations and cellular inflammatory reactions played significant roles in the related pathophysiological processes. Clinician should recognize the cardiovascular and metabolic impacts of MetS in men with LUTS, early risk factors optimization and use of appropriate medical therapy may possibly alter or slower the progression of LUTS/BPH, and potentially avoid unnecessary morbidities and mortalities from cardiovascular and metabolic diseases for those men.

    To investigate the molecular mechanisms involved in coagulation factor expression and/or function during direct hyperplasia (DH)-mediated liver regeneration. Direct hyperplasia-mediated liver regeneration was induced in female C57BL/6 mice by administering 1,4-bis[2-(3,5-dichloropyridyloxy)] benzene (TCPOBOP), a representative hepatomitogen. Mice were weighed and sacrificed at various time points [Day 0 (D0: prior to injection), 3 h, D1, D2, D3, and D10] after TCPOBOP administration to obtain liver and blood samples. Using the RNA samples extracted from the liver, a comprehensive analysis was performed on the hepatic gene expression profiling of coagulation-related factors by real-time RT-PCR (fibrinogen, prothrombin, factors V, VII, VIII, IX, X, XI, XII, XIIIbeta, plasminogen, antithrombin, protein C, protein S, ADAMTS13, and VWF). The corresponding plasma levels of coagulation factors (fibrinogen, prothrombin, factors V, VII, VIII, IX, X, XI, XII, XIII, and VWF) were also analyzed and compared with their mRNA levels. Gavage administration of TCPOBOP (3 mg/kg body weight) resulted in a marked and gradual increase in the weight of the mouse livers relative to the total body weight to 220% by D10 relative to the D0 (control) ratios. At the peak of liver regeneration (D1 and D2), the gene expression levels for most of the coagulation-related factors (fibrinogen, prothrombin, factors V, VII, VIII, IX, XI, XII, XIIIbeta, plasminogen, antithrombin, protein C, ADAMTS13, VWF) were found to be down-regulated in a time-dependent manner, and gradually recovered by D10 to the basal levels. Only mRNA levels of factor X and protein S failed to show any decrease during the regenerative phase. As for the plasma levels, 5 clotting factors (prothrombin, factors VIII, IX, XI, and XII) demonstrated a significant decrease (Pfactors, factor IX and factor XI showed the most dramatic decline in their activities by about 50% at D2 compared to the basal levels, and these reductions in

    There is little information on the private lives of women engaged in sex work, particularly how power dynamics within intimate relationships may affect intimate partner violence (IPV). Using baseline data of sex workers enrolled in a longitudinal cohort, "An Evaluation of Sex Workers' Health Access" (AESHA), the present study examined the association between sexual relationship power and IPV among sex workers in non-commercial partnerships in Vancouver, Canada. Pulweritz's Sexual Relationship Power Scale (SRPS) and The World Health Organization (WHO) Intimate Partner Violence against Women Scale (Version9.9) were used. Bivariable and multivariable logistic regression techniques were used to investigate the potential confounding effect of sexual relationship power on IPV among sex workers. Adjusted odds ratios (AOR) and 95% confidence intervals (CIs) were reported. Of 510 sex workers, 257 (50.4%) reported having an non-commercial intimate partner and were included in this analysis. In the past 6 months, 84 (32.7%) sex workers reported IPV (physical, sexual or emotional). The median age was 32 years, 39.3% were of Aboriginal ancestry, and 27.6% were migrants. After controlling for known confounders (e.g., age, Aboriginal ancestry, migrant status, childhood trauma, non-injection drug use), low relationship power was independently associated with 4.19 increased odds (95% CI: 1.93-9.10) and medium relationship power was associated 1.95 increased odds (95% CI: 0.89-4.25) of IPV. This analysis highlights how reduced control over sexual-decision making is plays a critical role in IPV among sex workers, and calls for innovation and inclusive programming tailored to sex workers and their non-commercial intimate partnerships.

    Social scientists have increasingly invested in understanding how to improve data quality and measurement of sensitive topics in household surveys. We utilize the technique of list randomization to collect measures of physical intimate partner violence in an experimental impact evaluation of the Government of Zambia's Child Grant Program. The Child Grant Program is an unconditional cash transfer, which targeted female caregivers of children under the age of 5 in rural areas to receive the equivalent of US $24 as a bimonthly stipend. The implementation results show that the list randomization methodology functioned as planned, with approximately 15% of the sample identifying 12-month prevalence of physical intimate partner violence. According to this measure, after 4 years, the program had no measurable effect on partner violence. List randomization is a promising approach to incorporate sensitive measures into multitopic evaluations; however, more research is needed to improve upon methodology for application to measurement of violence.

    Benign prostatic hyperplasia (BPH) is a chronic condition common in older men that can result in bothersome lower urinary tract symptoms. The molecular mechanisms and networks underlying the development and the progression of the disease are still far from being fully understood. BPH results from smooth muscle cell and epithelial cell proliferation, primarily within the transition zone of the prostate. Apoptosis and inflammation play important roles in the control of cell growth and in the maintenance of tissue homeostasis. Disturbances in molecular mechanisms of apoptosis machinery have been linked to BPH. Increased levels of the glycoprotein Dickkopf-related protein 3 in BPH cause an inhibition of the apoptosis machinery through a reduction in B cell lymphoma (Bcl)-2 associated X protein (Bax) expression. Inhibitors of apoptosis proteins influence cell death by direct inhibition of caspases and modulation of the transcription factor nuclear factor-κB. Current pharmacotherapy targets either the static component of BPH, including finasteride and dutasteride, or the dynamic component of BPH, including α-adrenoceptor antagonists such as tamsulosin and alfuzosin. Both these classes of drugs significantly interfere with the apoptosis machinery. Furthermore, phytotherapic supplements and new drugs may also modulate several molecular steps of apoptosis.

    2015-01-01

    The purpose of this study is to provide an update on recent developments regarding the medical management of male lower urinary tract symptoms (LUTS). Silodosin improves storage/voiding symptoms and nocturia and is effective within the framework of a trial without a catheter. 5α-reductase inhibitors (5ARIs) are not associated with male breast cancer development. Alcohol consumption seems to increase the risk of high-grade prostate cancer under 5ARIs. The combination of α-blocker and 5ARIs remains a well established concept for benign prostatic hyperplasia/LUTS patients with an enhanced risk of disease progression. Tadalafil 5 mg/day monotherapy is a valid option particularly for men with LUTS and erectile dysfunction; the combination of Tadalafil 5 mg/day with a 5ARI is an interesting approach. The fixed-dose combination of α-blocker and antimuscarinic provides advantages regarding storage symptom improvement. This approach is currently primarily recommended as an add-on strategy. Mirabegron opens new horizons in the management of male LUTS and has no negative (but also no positive) urodynamic effects. Several encouraging novel approaches are currently in the experimental phase and might enhance our therapeutic armamentarium in the near future. The recent literature refines our knowledge on current therapeutic options and provides further evidence for an individualized, risk-adapted approach for male LUTS mainly depending on symptoms status, comorbidities (i.e. erectile dysfunction) and risk of disease progression.

    Hydrodynamic cavitation is a physical phenomenon characterized by vaporization and bubble formation in liquids under low local pressures, and their implosion following their release to a higher pressure environment. Collapse of the bubbles releases high energy and may cause damage to exposed surfaces. We recently designed a set-up to exploit the destructive nature of hydrodynamic cavitation for biomedical purposes. We have previously shown that hydrodynamic cavitation could kill leukemia cells and erode kidney stones. In this study, we analyzed the effects of cavitation on prostate cells and benign prostatic hyperplasia (BPH) tissue. We showed that hydrodynamic cavitation could kill prostate cells in a pressure- and time-dependent manner. Cavitation did not lead to programmed cell death, i.e. classical apoptosis or autophagy activation. Following the application of cavitation, we observed no prominent DNA damage and cells did not arrest in the cell cycle. Hence, we concluded that cavitation forces directly damaged the cells, leading to their pulverization. Upon application to BPH tissues from patients, cavitation could lead to a significant level of tissue destruction. Therefore similar to ultrasonic cavitation, we propose that hydrodynamic cavitation has the potential to be exploited and developed as an approach for the ablation of aberrant pathological tissues, including BPH.

    Even though rice hull has various physiological functions with high antioxidant potential, the molecular mechanism(s) underlying the effects of rice hull on benign prostatic hyperplasia (BPH) have not been evaluated. The aim of this study was to determine the protective effect of rice hull water extract (RHE) against BPH, which is a common disorder in elderly men and involves inflammation that induces an imbalance between cell proliferation and cell death. In this study, RHE-treated mice exhibited lower prostate weights and ratios of prostate weight to body weight compared to those for the BPH-induced group. In addition, RHE-treated mice had lower serum levels of dihydrotestosterone, mRNA expression of 5α-reductase2, and protein expressions of proliferating cell nuclear antigen (PCNA). Furthermore, RHE treatment significantly decreased cell proliferation by regulating the expression levels of inflammatory-related proteins (iNOS and COX-2) and apoptosis-associated proteins (Fas, FADD, procaspase-8, -3, and Bcl-2 family proteins). These results suggest that RHE could protect against the development of BPH through its anti-inflammatory and apoptotic properties and has good potential as a treatment for BPH.

    Management of adult patients with classic congenital adrenal hyperplasia (CAH) is challenging and often complicated by obesity, metabolic syndrome, and adverse cardiovascular risk. Alterations in weight can influence cortisol kinetics. A 19-year-old woman with classic CAH and morbid obesity experienced persistent elevations of androgen levels while receiving oral glucocorticoid therapy. Control of adrenal androgens was improved with continuous subcutaneous hydrocortisone infusion therapy, but obesity-related comorbidities persisted. After undergoing sleeve gastrectomy, the patient experienced dramatic weight loss, with improvement in insulin sensitivity and fatty liver in the postbariatric period. Cortisol clearance studies performed to evaluate changes in hydrocortisone dose requirements showed marked alternations in cortisol pharmacokinetics with decreases in volume of distribution and cortisol clearance, along with an increase in area under the curve for cortisol. Hydrocortisone dose was subsequently decreased 34% by 15 months after surgery. Effective control of androgen excess on this lower hydrocortisone dose was achieved and continues 27 months after surgery. This case highlights obesity-related complications of glucocorticoid replacement therapy in the management of CAH. Individual patient factors, such as fatty liver disease and insulin resistance, can have a clinically important effect on cortisol metabolism. Bariatric surgery was a safe and effective treatment of obesity in this patient with CAH and should be considered for patients with CAH and multiple obesity-related comorbidities.

    Currently, there are not many data on the evolution of nodular regenerative hyperplasia (NRH) associated or not with underlying diseases and in particular that associated with common variable inmunodeficiency (CVID). Twenty cases of NRH are presented, and the differences between the cases associated with CVID and those related to other diseases are analysed. Retrospective and descriptive study over a period of 14 years. Twelve out of the 20 patients were men; the median age was 51 years. CVID was the main illness associated with NRH. In patients with CVID and NRH, gastrointestinal haemorrhage was more common, all the patients had high gamma glutamyl transferase and alkaline phosphatase and none had altered albumin and bilirubin levels compared to the patients without CVID. On follow-up, 50% of patients with CVID (2/4) had died compared to 33.3% (5/15) without CVID. NRH in patients with CVID seems to have more biochemical data of anicteric cholestasis and portal hypertension and could be associated with lower survival. Copyright © 2015 Elsevier España, S.L.U.

    Advanced prostate cancer undergoing androgen receptor pathway inhibition (ARPI) eventually progresses to castrate-resistant prostate cancer (CRPC), suggesting that (i) androgen receptor (AR) blockage is incomplete, and (ii) there are other critical molecular pathways contributing to prostate cancer (PCa) progression. Although most PCa occurs in the epithelium, prostate stroma is increasingly believed to play a crucial role in promoting tumorigenesis and facilitating tumor progression. In the stroma, sex steroid hormone receptors such as AR and estrogen receptor-α are implicated to have important functions, whereas the progesterone receptor (PR) remains largely under-investigated despite the high sequence and structural similarities between PR and AR. Stromal progesterone/PR signaling may play a critical role in PCa development and progression because not only progesterone is a critical precursor for de novo androgen steroidogenesis and an activator of mutant androgen receptors, but also PR functions in a ligand-independent manner in various important pathways. In fact, recent progress in our understanding of stromal PR function suggests that this receptor may exert an inhibitory effect on benign prostatic hyperplasia (BPH), reactive stroma development, and PCa progression. These early findings of stromal PR warrant further investigations as this receptor could be a potential biomarker and therapeutic target in PCa management. Copyright © 2016 Elsevier Ltd.

    To evaluate the outcome of a cohort of young women treated with progestin for fertility-sparing management of endometrial atypical hyperplasia (AH) and endometrial carcinoma (EC). This retrospective multicentre cohort study included women under the age of 40 years treated conservatively for AH and EC to preserve fertility using progestin for at least 3 months. Four inclusion criteria were defined: (i) the presence of AH or grade 1 EC confirmed by two pathologists (including a reference pathologist); (ii) the use of conservative management for fertility sparing; (iii) adequate radiological examination before conservative management; and (iv) a minimal follow-up time of one year. Twenty-two patients fulfilled the inclusion criteria (8 had EC, and 14 had AH). After progestin treatment, 17 patients responded. Among the 17 patients who experienced remission, three also experienced disease relapse. One patient initially diagnosed with AH experienced progression of her disease to stage IIIA EC. Ten pregnancies were achieved in eight patients. Fertility-sparing management using progestin offers the opportunity to fulfil maternal desires in young patients diagnosed with AH and EC. However, progression of the disease is possible and close follow-up is needed.

  2. Ablation of benign prostatic hyperplasia using microbubble-mediated ultrasound cavitation.

    2010-04-01

    Benign prostatic hyperplasia (BPH) is a world-wide common disease in elderly male patients. A number of invasive physiotherapies have been used to replace prostatectomy. In this article we report our hypothesis of using microbubbles-mediated ultrasound cavitation effects to ablate prostatic tissues. Microbubble ultrasound contrast agent is widely used contrast media in ultrasonography, yet it is also found to act as cavitation nuclei or enhancer. Once excited by a high peak pressure ultrasound pulse, the mechanical effects, like shock wave and microstream, released from cavitation could produce a series of bioeffects, contributing to sonoporation, microvascular rupture and hematoma. BPH is known to have hyperplastic neovasculature and this make it possible to be disrupted by the physical effects of cavitation under existing microbubbles in circulation. Mechanical ablation of prostatic capillary or small vessels could result in pathological alterations such as thrombosis, micro-circulation blockage, prostatic necrosis and atrophia. Thereupon it could effectively treat BPH by nontraumatic ways. (c) 2009 Elsevier Ltd. All rights reserved.

    Lung cancer is the leading cause of cancer-related mortality worldwide. Early detection or prevention strategies are urgently needed to increase survival. Hyperplasia is the first morphologic change that occurs in the bronchial epithelium during lung cancer development, followed by squamous metaplasia, dysplasia, carcinoma in situ, and invasive tumor. The current study was designed to determine the molecular mechanisms that control bronchial epithelium hyperplasia. Using primary normal human tracheobronchial epithelial (NHTBE) cells cultured using the 3-dimensional organotypic method, we found that the epidermal growth factor receptor (EGFR) ligands EGF, transforming growth factor-alpha, and amphiregulin induced hyperplasia, as determined by cell proliferation and multilayered epithelium formation. We also found that EGF induced increased cyclin D1 expression, which plays a critical role in bronchial hyperplasia; this overexpression was mediated by activating the mitogen-activated protein kinase pathway but not the phosphoinositide 3-kinase/Akt signaling pathway. Erlotinib, an EGFR tyrosine kinase inhibitor, and U0126, a MEK inhibitor, completely inhibited EGF-induced hyperplasia. Furthermore, a promoter analysis revealed that the activator protein-1 transcription factor regulates EGF-induced cyclin D1 overexpression. Activator protein-1 depletion using siRNA targeting its c-Jun component completely abrogated EGF-induced cyclin D1 expression. In conclusion, we demonstrated that bronchial hyperplasia can be modeled in vitro using primary NHTBE cells maintained in a 3-dimensional (3-D) organotypic culture. EGFR and MEK inhibitors completely blocked EGF-induced bronchial hyperplasia, suggesting that they have a chemopreventive role. PMID:21505178

  6. The INTIMATE event stratigraphy and recommendations for its use

    2014-05-01

    The North Atlantic INTIMATE (INtegration of Ice-core, MArine and TErrestrial records) group has previously recommended an Event Stratigraphy approach for the synchronisation of records of the Last Termination using the Greenland ice core records as the regional stratotypes. A key element of these protocols has been the formal definition of numbered Greenland Stadials (GS) and Greenland Interstadials (GI) within the past glacial period as the Greenland expressions of the characteristic Dansgaard-Oeschger events that represent cold and warm phases of the North Atlantic region, respectively. Using a recent synchronization of the NGRIP, GRIP, and GISP2 ice cores that allows the parallel analysis of all three records on a common time scale, we here present an extension of the GS/GI stratigraphic template to the entire glacial period. In addition to the well-known sequence of Dansgaard-Oeschger events that were first defined and numbered in the ice core records more than two decades ago, a number of short-lived climatic oscillations have been identified in the three synchronized records. Some of these events have been observed in other studies, but we here propose a consistent scheme for discriminating and naming all the significant climatic events of the last glacial period that are represented in the Greenland ice cores. In addition to presenting the updated event stratigraphy, we make a series of recommendations on how to refer to these periods in a way that promotes unambiguous comparison and correlation between different proxy records, providing a more secure basis for investigating the dynamics and fundamental causes of these climatic perturbations. The work presented is a part of a manuscript under review for publication in Quaternary Science Reviews. Author team: S.O. Rasmussen, M. Bigler, S.P.E. Blockley, T. Blunier, S.L. Buchardt, H.B.

    2010-01-01

    A Heideggerian hermeneutic phenomenological approach was used to investigate the lived experience of women in Botswana who had experienced emotional abuse in intimate relationships. Hermeneutic phenomenology is concerned with the human experience as it is lived. Ten educated Botswana women who had formal employment and have been in intimate relationships for longer than ten years, narrated their life experiences with abusive men. Extensive interviews took place over a six month period. Sociocultural practices in Botswana emerged as salient factors that contribute to emotional abuse and predispose women to mental illness. Entwined in these cultural practices are issues of age, ethnicity, payment of lobola (bride price), financial standing, change of name, and relocation to the man's residence. Education and employment seem to worsen the abuse. Depression and anxiety are common results of abuse. Understanding how the sociocultural factors perpetuate abuse can assist nurses in the way they provide health care services to women.

    Full Text Available The present study sought to estimate the magnitude of intimate partner violence (IPV in university students in southern Chile; to describe its manifestations, its associated factors, consequences and coping strategies. Method: A descriptive quantitative design was used, the sample was constituted by 447 university students randomly selected balanced by sex. Participants were asked about violent behaviour conduct through a questionnaire. Results: 57% of those questioned reported having experienced some psychological abuse, 26% reported physical violence at least once in their lifetime. Associated factors to receive physical violence were: sex, suffering psychological violence, favourable attitudes towards violence, and low religious participation. Associated factor to receive psychological violence was: sex, physical violence received, favourable attitudes towards the violence, and the length of the relationship. Discussion: Typical features of intimate partner violence in college life settings seem to favor its invisibility, thus turning it into a difficult phenomenon to approach and to prevent.

    2017-07-01

    A case is presented in which the staff of a long-term care facility discovers that the husband of a resident with dementia is engaged in sexual activity with her. The case illustrates a dilemma for long-term care facilities that create a home-like environment with a goal of maximizing residents' autonomy while ensuring their safety. An approach to assessing capacity to consent to intimate sexual activity is described, followed by guidelines that nursing homes can implement to support residents who wish to engage in sexual activity. Recommendations are also offered for supporting long-term care staff and family members of residents who are interested in intimate sexual activity. © 2017 American Medical Association.

    Pseudoangiomatous stromal hyperplasia (PASH) is a benign lesion of myofibroblasts that is composed of a network of slit-like channels that resemble vascular spaces. The aims of this study were to document the frequency of PASH in core needle biopsy specimens (CNBS) of the breast, to describe which histopathologic findings coexist with PASH and to examine any endothelial cell differentiation. We reevaluated hematoxylin and eosin-stained sections of all CNBS that were obtained during a 1-year period. First, we performed CD34 and CD31 immunostainings to highlight the areas of PASH, then performed D2-40/podoplanin (lymphatic endothelial marker) and Fli-1 (vascular endothelial cell marker) immunostains. The total number of CNBS was 412. Areas of PASH were noted in 37 of the 412 cases (9%), with a mean age of 38.5 years. The lesions that were described in association with PASH were "benign breast parenchyma with stromal fibrosis" (17/37; 46%), "fibroepithelial tumors" (17/37; 46%), "columnar cell changes (CCC)" (2/37; 5%), and "invasive carcinoma" (1/37; 3%). There were 2 cases of CCC within the foci of PASH (direct contact with PASH), and 8 additional cases of CCC that coexisted in the same specimen but were not in direct contact. There was no staining for D2-40 or Fli-1 within PASH foci. PASH lesions occurred with a frequency of 9% in CNBS and were mostly in association with benign breast lesions in premenopausal women. CCC was determined as an accompanying epithelial lesion within or near PASH areas. No obvious immunopositivity compatible with endothelial cell differentiation was revealed.

    Focal nodular hyperplasia (FNH) is a rare benign hepatocellular tumor occurring in noncirrhotic patients, mostly females, 20-50 years of age. It is usually asymptomatic. The authors took the lead from 5 cases of FNH studied over last year to analyze the different patterns exhibited by the condition on the various imaging techniques currently available. At scintigraphy with 99mTc DISIDA or with TcSC, FNH can be hyper, normal, or hypocaptating. On US scans, the lesion is often homogeneous and isoechoic, but it can also be hyper/hypoechoic. With Doppler US, high-flow signals can be observed. On unenhanced CT scans the lesion is solid, well-demarcated, isodense or slightly hyperdense; sometimes it shows a central hypodense area corresponding to fibrovascular scar. On postcontrast scans it appears hyper/isodense. At dynamic CT the lesion density, which is high during the arterial phase, decreases quickly in the parenchymal and the venous phases and reaches equal/inferior values to surrounding liver parenchyma. On liver angio-CT it is sometimes possible to visualize the bile ducts in the central scar. At angiography, FNH is hypervascular and homogeneous. On MR scans, in T1-weighted SE sequences, the condition is isointense or slightly hypointense, whereas on T2-weighted pulse sequences it is slightly hyperintense; the central scar is hypointense on T1, and hyperintense on T2, weighted scans. As we have no pathognomonic patterns but only orientative ones, a reliable differential diagnosis with hepatocellular adenoma (HA) and fibrolamellar hepatocellular carcinoma (FL-HCC) must be based on biopsy or cytology or, even better, histology. The differential diagnosis is nevertheless necessary because, while FNH does not usually require a surgical approach but only a radiological follow-up, both HA (due to possible bleeding and degeneration) and FL-HCC require surgery.

    Background We reviewed our experience with micronodular adrenal hyperplasia (MAH), its pigmented variant primary pigmented nodular adrenocortical disease (PPNAD), and the association with Carney’s Complex (CNC) in order to better characterize the disorders. Methods This study is a retrospective analysis of clinical data and operative reports of 34 patients identified with MAH and/or PPNAD who underwent resection between 1969 and 2006 at the Clinical Research Center, an inpatient research hospital, at the National Institutes of Health. Symptoms and anthropometric and biochemical data were used to evaluate effect of resection. Results Fifteen patients (44%) presented as adults and 19 (56%) as children. Twenty five patients (74%) presented with non-cyclic Cushing syndrome and nine patients (26%) presented with cyclic Cushing Syndrome. Thirty one patients underwent bilateral resection; this was curative biochemically in 30 patients. Fourteen operations were performed laparoscopically (41%), and 20 were perfomed as open resections (59%). There was one post-operative complication in the laparoscopic group (7%) and 6 complications in the open group (30%) (p=0.20). Follow-up was available for 25 patients (74%). Statistically significant improvements in anthropometrics were observed for both adults and children. The most frequent manifestation of CNC requiring additional operation was cardiac myxoma which was associated strongly with an atypical (cyclic) presentation of Cushing Syndrome (p=0.009). Conclusion Cushing Syndrome due to MAH and PPNAD may be cured by bilateral adrenal resection. All patients should be screened for manifestations of CNC at the time of adrenal diagnosis with particular attention to cardiac disease. PMID:18549891

    The medical armamentaria for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) have been extensively implemented over the past decade. Nevertheless, the timeliest moment for a possible treatment has not been fully established. A systematic literature search in January 1996 until June 2016 was performed to answer the following question: in men with LUTS due to BPH, does early treatment result in better outcome? An ad hoc Population/patient Intervention/indicator Comparator/control Outcome (PICO) was developed.The Medline, PubMed and Scopus databases were searched. Each article title and abstract were reviewed for relevance and appropriateness with regard to the topic of this review. Overtime, the introduction of novel medications and the implementation of surgical techniques have significantly improved the treatment outcomes and markedly reduced the rate of BPH surgery. Early treatments in patients at risk of disease progression may result in better clinical outcomes than a delayed approach. However, the evidence to support early intervention remains weak and criteria to identify the patient phenotype that could best benefit from immediate treatment remain ill-defined.On the contrary, the patients who ultimately undergo surgery following prolonged pharmacological treatment present with larger prostates, older age and comorbidities. At the same time, the technological progress has partly compensated this critical scenario, and commonly, a nonpejorative trend has been recorded in perioperative complications. The ideal moment to begin a treatment in LUTS/BPH patients is still uncertain, and surprisingly, rare good quality studies are available on this topic.

    Full Text Available Purpose To assess the outcome of transurethral plasmakinetic vaporization (PKVP in the management of benign prostatic hyperplasia (BPH. Patients and methods From August 2010 to May 2012, 60 patients with obstructive LUTS due to BPH were included in the study. All patients were evaluated by International Prostate Symptom Score (IPSS, general examination, digital rectal examination, PSA, routine laboratory examinations, pelvi-abdominal ultrasound, trans-rectal ultrasound, and uroflowmetry. Patients with Qmax of 8 and a prostate volume of >40 mL underwent transurethral PKVP. Results Mean age of the patients was 66.8±4.5 years. The mean times of the operation, post-operative bladder irrigation, and post-operative catheterization were 63.8±13.9 minutes, 15.2±5.7 hours, and 23.9±5.2 hours, respectively. At 3 months of follow-up, there were significant reductions in the mean IPSS from 23.4±3.5 to 9.2±3.7 (P=0.4, mean PSA from 3.03±2.2 ng/mL to 1.2±1.04 ng/mL (P value=0.02, mean post voiding residual urine from 149.8±59.5 mL to 46.9±24.1 mL (P value <0.01, and mean prostate volume from 72.8±10.3 mL to 22.7±6.1 mL (P value <0.01. Also, there was a statistically significant increase in the mean Q max. from 8.7±2.4 mL/s to 19.5±3.5 mL/s (P value <0.01. Conclusion PKVP is an effective and safe treatment option in the management of symptomatic BPH.

    To describe magnetic resonance imaging (MRI) features of intravascular papillary endothelial hyperplasia (IPEH), to identify findings differentiating IPEH of the finger from that of other locations, and to correlate these with pathology. Nineteen patients with 20 I.E. masses of the finger (n = 13) and other locations (n = 7) were evaluated. All patients underwent MRI, and the results were correlated with pathology. Seventeen IPEHs, including all IPEHs of the finger, were located in the subcutis, the three other lesions in the muscle layer. On T1WI, all masses were isointense or slightly hyperintense. IPEHs of the finger (n = 13) revealed focal hyperintense nodules (n = 2) or central hypointensity (n = 2) on T1WI, hypointensity with a hyperintense rim (n = 7), hyperintensity with hypointense nodules (n = 5), or isointensity with a hypointense rim (n = 1) on T2WI, and rim enhancement (n = 5), heterogeneous enhancement with nodular nonenhanced areas (n = 6), peripheral nodular enhancement (n = 1), or no enhancement (n = 1) on gadolinium-enhanced T1WI. IPEHs of other locations (n = 7) demonstrated focal hyperintense nodules (n = 5) on T1WI, hyperintensity with hypointense nodules (n = 5) or heterogeneous signal intensity (n = 2) on T2WI, and rim or rim and septal enhancement (n = 6) or peripheral nodular enhancement (n = 1). Microscopically, IPEHs were composed of thrombi that were hypointense on T2WI and papillary endothelial proliferations that showed T2 hyperintensity and enhancement. MRI of finger IPEH reveals well-demarcated subcutaneous masses with hypointensity or hypointense nodules with peripheral hyperintensity on T2WI, as well as peripheral enhancement. T1 hyperintense nodules, internal heterogeneity on T2WI, and septal enhancement are more common in IPEH of other locations. (orig.)

    Sex assignment in infancy for patients with disorder of sex development (DSD) is a challenging problem. Some of the patients with congenital adrenal hyperplasia (CAH) have DSD that may affect their gender identity. The study aimed to assess gender identity in patients with CAH. In this study, 52 patients with CAH, including 22 prepubertal children and 30 adolescents and adults, were assessed using two separate gender identity questionnaires for children and adults based on the criteria of diagnostic and statistical manual of mental disorders, 5th edition. In the children group, compatibility was seen between gender identity and rearing gender. In the adult group, there were three cases of mismatching between gender identity and sex assignment composed of two females with poor control and one male with good control with 21-hydroxylase deficiency (21-OHD). Three girls with 11-hydroxylase deficiency (11-OHD) were reared as boy. Two of them with late diagnosis at 5 and 6 years of age had pseudoprecocious puberty. Parents and children did not accept to change the gender. One of them is 36 years old now, is depressed and unsatisfied with her gender, another girl is still child and has male sexual identity. One girl with 11-OHD and early diagnosis at birth with Prader 5 virilization but with good hormonal control was changed to female gender at 12 years of age when female sexual characteristics appeared; she is 34-years-old now, married, and with two children, and she is satisfied with her gender. In patients with CAH, gender identity disorder is a rare finding. Hormonal control, social, familial, and religious beliefs have impacts on gender identity of these patients.

    Interleukin 15 (IL-15) is a pro-inflammatory cytokine that modulates T cell recruitment and activation, independent of antigen. It has been detected in human atherosclerotic plaques and atherosclerotic plaques of apoE-/- mice. IL-15 regulates fractalkine (FKN)-CX3CR1 chemokine signaling which is involved in atherogenesis and promotes SMC proliferation. We investigated the role of IL-15 in intimal thickening after arterial injury. Treatment of serum-stimulated SMC with IL-15 in vitro attenuated proliferation and suppressed CX3CR1 and FKN mRNA expression. The role of endogenous IL-15 in vivo was investigated in injured carotid arteries of mice. Periadventitial arterial injury resulted in increased IL-15 expression in the media and neointima, paralleled by increased IL-15 receptor α expression. Blockade of endogenous IL-15 increased intimal thickening. FKN and CX3CR1 expression increased after injury and were further augmented after IL-15 blockade. These data suggest that endogenous IL-15 attenuated intimal thickening after arterial injury. The potential mechanism of action is suppression of CX3CR1 signaling

    To evaluate the impact of intimate partner violence on the quality of life in Obstetric/Gynecological (OBGYN) patients. A total of 1614 OBGYN patients were classified into four groups (Group 1: requesting termination of pregnancy, n=300; Group 2: infertility patients, n=500; Group 3: other general gynecological patients, n=300; Group 4: obstetric patients, n=514) were successfully interviewed in the absence of their male partners, using a structured questionnaire modified from the Abuse Assessment Screen Questionnaire. Those who reported ever having been abused, together with an equal number of non-abused women as controls, were asked to complete the World Health Organization Quality of Life Measure - Abbreviated version (Hong Kong) Questionnaire. The overall lifetime prevalence of intimate partner violence was 7.2%, with the lifetime prevalence being 12.7%, 1.8%, 4.7%, and 10.9% respectively in Groups 1-4. The mean quality of life domain scores among the abused victims were significantly lower in the physical health domain, social relationship domain, environment domain and psychological health domain. The baseline quality of life of the victims of intimate partner violence is significantly impaired compared with the non-abused controls.

    Full Text Available OBJECTIVE : To investigate the association between common mental disorders and intimate partner violence during pregnancy. METHODS : A cross sectional study was carried out with 1,120 pregnant women aged 18-49 years old, who were registered in the Family Health Program in the city of Recife, Northeastern Brazil, between 2005 and 2006. Common mental disorders were assessed using the Self-Reporting Questionnaire (SRQ-20. Intimate partner violence was defined as psychologically, physically and sexually abusive acts committed against women by their partners. Crude and adjusted odds ratios were estimated for the association studied utilizing logistic regression analysis. RESULTS : The most common form of partner violence was psychological. The prevalence of common mental disorders was 71.0% among women who reported all form of violence in pregnancy and 33.8% among those who did not report intimate partner violence. Common mental disorders were associated with psychological violence (OR 2.49, 95%CI 1.8;3.5, even without physical or sexual violence. When psychological violence was combined with physical or sexual violence, the risk of common mental disorders was even higher (OR 3.45; 95%CI 2.3;5.2. CONCLUSIONS : Being assaulted by someone with whom you are emotionally involved can trigger feelings of helplessness, low self-esteem and depression. The pregnancy probably increased women`s vulnerability to common mental disorders

  9. Intimate Partner Jealousy and Femicide Among Former Ethiopians in Israel.

    2018-02-01

    Ethiopian immigrant women in Israel are overrepresented as victims of femicide; they are killed at more than 16 times the rate of the general population. This article suggests integrating current theoretical and empirical models to explain Ethiopian femicide, and stresses that considering psychological or sociocultural explanations as risk factors alone is not enough to understand this phenomenon. We distinguish between risk factors and triggers for femicide against Ethiopian women. While sociocultural and even psychological changes are risk factors for femicide, one, two, or three main triggers may activate such potential risk factors, such as the woman's willingness (WW) to leave the intimate relationship, sexual jealousy (SJ), and formal complaints against the abusive partner. The first two triggers are jealousy oriented. To analyze this phenomenon in Israel, we examined all court decisions on intimate partner homicide (IPH) from 1990 to 2010. After reading former studies on IPH and identifying important variables that could explain the phenomenon, we first catalogued the data in every decision and verdict according to main independent variables mentioned in the literature. The study population consists of first-generation immigrants, N = 194: native Israelis (47%), new immigrants from the former Soviet Union (FSU; 31%), and Ethiopians (16%). Our analysis of court decisions reveals that triggers containing jealousy components are responsible for 83% of femicide cases committed by Ethiopian men, in comparison with native Israelis (77%) and immigrant Russian men (66%) who murdered their intimate partners. In addition, there is a significant correlation among motive (jealousy), method of killing (stabbing), and "overkilling" (excessive force).

    Maintaining safety is of utmost importance during research involving participants who have experienced intimate partner violence (IPV). Limited guidance on safety protocols to protect participants is available, particularly information related to technology-based approaches to informed consent, data collection, and contacting participants during the course of a study. The purpose of the article is to provide details on the safety protocol developed and utilized with women receiving care at an urban HIV clinic and who were taking part in an observational study of IPV, mental health symptoms, and substance abuse and their relationship to HIV treatment adherence. The protocol presents the technological strategies to promote safety and allow autonomy in participant decision-making throughout the research process, including Voice over Internet Protocol telephone numbers, and tablet-based eligibility screening and data collection. Protocols for management of participants at risk for suicide and/or intimate partner homicide that included automated high-risk messaging to participants and research staff and facilitated disclosure of risk to clinical staff based on participant preferences are discussed. Use of technology and partnership with clinic staff helped to provide an environment where research regarding IPV could be conducted without undue burden or risk to participants. Utilizing tablet-based survey administration provided multiple practical and safety benefits for participants. Most women who screened into high-risk categories for suicide or intimate partner homicide did not choose to have their results shared with their healthcare providers, indicating the importance of allowing participants control over information sharing whenever possible.

    Full Text Available This study investigated the association between unintended pregnancy and intimate partner violence before pregnancy. A cross-sectional study was carried out with 1,054 women, aged 18 to 49, in Recife, Northeastern Brazil, from July 2005 to March 2006. Non-conditional logistic regression analysis was performed with a hierarchical strategy for entering variables into the model, according to the conceptual framework defined. Unintended pregnancy was reported by 60.3% (636 women. Intimate partner violence prior to the pregnancy was associated with unintended pregnancy (ORadj = 1.57; 95%CI: 1.17-2.11, even when adjusted for the women's sociodemographic characteristics, the partner's behaviour, and the relationship dynamic. When the association was adjusted for the use of contraception and the partner's refusal to use contraception, the association was no longer significant, suggesting that the effect of partner violence on unintended pregnancy may be mediated by these variables. The findings point to the need of screening for intimate partner violence in reproductive health services.

    Benign prostatic hyperplasia (BPH) develops in elderly males when serumandrogens are relatively lower than in healthy younger males, but is not wellunderstood whether and how sex steroids are altered in prostatic hyperplasia.It is also uncertain that whether there is any change in sex steroids levelsin males older than 40 years of age. The use of androgens in elderly males isoften discouraged because of the probable worsening effect of androgens onprostatism. This study aimed to determine the relationship between prostatichyperplasia and sex steroid levels and whether there is any significantchange in these hormones after the age of 40 years. We studied healthy malesof >40 years with (n=92) or without (n=93) clinical prostatic hyperplasia.Serum testosterone, estradiol, gonadotrophins and sex hormone-bindingglobulin (SHBG) were compared. The hormones and SHGB were also correlatedwith age. No significant difference was found in any hormone in cases withprostatic hyperplasia as compared with the controls. There was no significantage-related change in any hormone except estradiol where as a negativecorrelation (P<0.003) with age was found. Serum sex steroids and SHGBremained unchanged in symptomatic prostatic hyperplasia and except forestrdoil there was no significant age-related change in serum testosterone,gonadotrophins and SHGB in healthy males after the fourth decade. Morestudies are needed to confirm the age-related decline of estrogens in males.(author)

    This study examined the coping styles used by sexual minority men who have experienced intimate partner violence, including sexual, emotional and physical victimisation, as well as physical injury. Although sexual minority men experience intimate partner violence at least as often as do heterosexuals, there is currently limited knowledge of intimate partner violence in this community or resources for sexual minority men who experience intimate partner violence. Cross-sectional design. Sexual minority men (N = 89) were recruited as part of a national online survey and completed questionnaires assessing lifetime experiences of intimate partner violence as well as various coping strategies. In terms of intimate partner violence, 34·8% of participants reported having been targets of sexual abuse, 38·2% targets of physical abuse, 69·7% targets of psychological abuse and 28·1% had experienced an injury as a result of intimate partner violence during their lifetime. Canonical correlation analyses found that intimate partner violence victimisation explained 32·5% of the variance in adaptive and 31·4% of the variance in maladaptive coping behaviours. In the adaptive coping canonical correlation, standardised loadings suggested that sexual minority men who experienced intimate partner violence resulting in injury were more likely to use religious coping, but less likely to use planning coping. In the maladaptive coping canonical correlation, sexual minority men who had been targets of intimate partner sexual victimisation and intimate partner violence resulting in injury tended to engage in increased behavioural disengagement coping. This study revealed several coping behaviours that are more or less likely as the severity of different forms of intimate partner violence increases. The identification of these coping styles could be applied to the development and modification of evidence-based interventions to foster effective and discourage ineffective coping styles

    Intimate coupling of photocatalysis and biodegradation (ICPB) technology is attractive for phenolic wastewater treatment, but has only been investigated using UV light (called UPCB). We examined the intimate coupling of visible-light-induced photocatalysis and biodegradation (VPCB) for the first time. Our catalyst was prepared doping both of Er(3+) and YAlO3 into TiO2 which were supported on macroporous carriers. The macroporous carriers was used to support for the biofilms as well. 99.8% removal efficiency of phenol was achieved in the VPCB, and this was 32.6% higher than that in the UPCB. Mineralization capability of UPCB was even worse, due to less adsorbable intermediates and cell lysis induced soluble microbial products release. The lower phenol degradation in the UPCB was due to the serious detachment of the biofilms, and then the microbes responsible for phenol degradation were insufficient due to disinfection by UV irradiation. In contrast, microbial communities in the carriers were well protected under visible light irradiation and extracellular polymeric substances secretion was enhanced. Thus, we found that the photocatalytic reaction and biodegradation were intimately coupled in the VPCB, resulting in 64.0% removal of dissolved organic carbon. Therefore, we found visible light has some advantages over UV light in the ICPB technology.

    Age at first marriage has risen substantially and birth rates are at a record low; people are spending more time in relationships that, by comparison, have fewer emotional, financial, and legal commitments. Little research has examined intimate partner violence (IPV) prevalence in current and former adult (vs. adolescent) dating relationships. Such information is relevant to federal firearms policies that are based on the nature of an intimate relationship. We examined assaultive behaviors by the type and status of the relationship - current spouse, former spouse, current boyfriend or girlfriend, and former boyfriend or girlfriend - in 31,206 IPV incidents responded to by Philadelphia police in 2013. Over 80% of the IPV incidents involved individuals in non-marital relationships. Incidents involving current boyfriends or girlfriends had the highest percentage of violent behaviors (e.g., punch, strangle). They also were more likely than current spouses to use bodily weapons (hands, fists, or feet) or non-gun weapons (knives, bats, etc.) (AOR = 1.19 and 1.43, respectively), to injure their victims (AOR = 1.37), and to be arrested (AOR = 1.46). Former unmarried partners had the highest odds of stalking their intimate (AOR = 3.37) and violating a restraining order (AOR = 2.61). Gun use was similar across relationship type. A growing portion of the population is not protected by federal policies designed to keep guns out of the hands of abusers. Current boyfriends and girlfriends are a risk to their intimates. Federal data collection practices and firearm policies merit updating to more fully take into account dating, same-sex marriage, and other partnerships. Copyright © 2018 Elsevier Inc.

    1986-01-01

    Susceptibility to photocarcinogenesis has been examined in several mouse strains and stocks including SENCAR, CD-1, BALB/c, C3H, C57Bl, and NZB. SENCAR mice are hypersusceptible to tumorigenesis caused by single high dose exposures to ultraviolet (UV) radiation but not by chronic low-dose exposures. SENCAR mice also exhibit an exaggerated and persistent epidermal hyperplasia in response to UV-induced tissue damage. The persistent hyperplasia is apparently due to a sustained proliferation of the epithelial basal cells, rather than to delayed cell differentiation. SENCAR mice did not exhibit persistent hyperplasia following other forms of tissue damage (surgical or thermal). In related studies, the levels of thymine dimers induced in SENCAR epidermis by UV radiation were comparable to those observed in BALB/c epidermis. In addition, no differences were found in the tissue distribution or persistence of thymine dimers in SENCAR and BALB/c skin

    Prostatic inflammation is of considerable importance to urologic research because of its association with benign prostatic hyperplasia and prostate cancer. However, the mechanisms by which inflammation leads to proliferation and growth remain obscure. Here, we show that insulin-like growth factors (IGFs), previously known as critical developmental growth factors during prostate organogenesis, are induced by inflammation as part of the proliferative recovery to inflammation. Using genetic models and in vivo IGF receptor blockade, we demonstrate that the hyperplastic response to inflammation depends on interleukin-1–driven IGF signaling. We show that human prostatic hyperplasia is associated with IGF pathway activation specifically localized to foci of inflammation. This demonstrates that mechanisms of inflammation-induced epithelial proliferation and hyperplasia involve the induction of developmental growth factors, further establishing a link between inflammatory and developmental signals and providing a mechanistic basis for the management of proliferative diseases by IGF pathway modulation.

    Focal epithelial hyperplasia (FEH), or Heck's disease, is a benign proliferative viral infection of the oral mucosa that is related to Human Papil-lomavirus (HPV), mainly subtypes 13 and 32. Although this condition is known to exist in numerous populations and ethnic groups, the reported cases among Caucasians are relatively rare. It presents as asymptomatic papules or nodules on the oral mucosa, gingiva, tongue, and lips. Histopathologically, it is characterized by parakeratosis, epithelial hyperplasia, focal acanthosis, fusion, and horizontal outgrowth of epithelial ridges and the cells named mitozoids. The purpose of this case report was to present 3 cases of focal epithelial hyperplasia in a pediatric age group. Histopathological and clinical features of cases are discussed and DNA sequencing analysis is reported in which HPV 13, HPV 32, and HPV 11 genomes are detected.

    The results of a immunomorphologic comprehensive study of epithelial-stromal relationships in the uterus hyperplasia and endometrial cancer suggest that the suppressor gene of cancer (PTEN) plays a key role in the process of neoplastic transformation of endometrial hyperplasia and adenocarcinoma development. For the first time the existence of two highly differentiated endometrial adenocarcinoma immunophenotype were detected The first one is a PTEN-negative endometrial aedenocarcinoma, characterized by an almost complete inhibition of tumor suppressor gene PTEN in the epithelium of the glands and stromal cell of the tumor The second type is a PTEN-positive endometrial adenocarcinoma, in which epithelial and stromal tumor suppressor gene PTEN activity has retained Based on these results we have formulated a hypothesis about the different types of endometrial hyperplasia morphogenesis and its possible transfer to cervical cancer associated with features of tumor suppressor gene PTEN.

    We investigated whether IL-33 is involved in mucus overproduction and goblet cell hyperplasia in eosinophilic chronic rhinosinusitis (ECRS). IL-33 mRNA was significantly higher in the eosinophilic CRS group than in the non-eosinophilic CRS group from human nasal polyps. IL-33 induced MUC5AC mRNA and MUC5AC protein, and also goblet cell hyperplasia at air liquid interface culture in human nasal epithelial cells. In addition to that, IL-33 induced MUC5B and FOXA3, and reduces FOXJmRNA. In conclusion, our present study demonstrated that the direct evidence of IL-33 which lead to increase mucin gene and protein expression, as well as goblet cell hyperplasia. This study provides novel insights into the role of IL-33 on mucus overproduction in eosinophilic inflammation of human airways. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Adrenocorticotropin-independent adrenal hyperplasias are rare diseases, which are classified into macronodular (>1 cm and micronodular (≤1 cm hyperplasia. Micronodular adrenal hyperplasia is subdivided into primary pigmented adrenocortical disease and a limited or nonpigmented form 'micronodular adrenocortical disease (MAD', although considerable morphological and genetic overlap is observed between the 2 groups. We present an unusual case of a 44-month-old girl who was diagnosed with Cushing syndrome due to MAD. She had presented with spotty pigmentation on her oral mucosa, lips and conjunctivae and was diagnosed with multiple bone tumors in her femur, pelvis and skull base at the age of 8 years. Her bone tumor biopsies were compatible with osteoblastoma. This case highlights the importance of verifying the clinicopathologic correlation in Cushing syndrome and careful follow-up and screening for associated diseases.

    Using a 1.5 T MR imaging unit, T1- and T2-weighted images were obtained before and after i.v. administration of chondroitin sulfate iron colloid (CSIC) in order to differentiate hepatocellular carcinoma (n=20) from adenomatous hyperplasia without atypia (n=16). Differentiation was made from the tumor-liver contrast to noise ratio (CNR) and visual evaluation of the nodule, with reference to signal intensity relative to that of the surrounding liver. The CNR of adenomatous hyperplasia was on T1-weighted images significantly decreased after CSIC administration (p<0.01). On T2-weighted images, there was no significant difference in CNR after CSIC administration. On the other hand, the CNR of hepatocellular carcinoma was significantly increased after CSIC administration on both T1- and T2-weighted images (p<0.01). CSIC reflects intratumor reticuloendothelial cellular functions, and is therefore useful in differentiating hepatocellular carcinoma from adenomatous hyperplasia without atypia. (orig.).

    Multilocular thymic cysts are rare and acquired lesions induced by an inflammatory arising within the thymus. We report a rare case of multilocular thymic cyst with follicular lymphoid hyperplasia in a 59-year-old female. Chest CT and MRI revealed a large multilocular cystic mass, which contains thick septa and nodules in the thymus. F-18 FDG PET/CT showed almost no FDG uptake of the multilocular cystic mass but moderate FDG uptake of the solid nodules. Extended total thymectomy was performed. Histopathological findings revealed follicular lymphoid hyperplasia of thymic tissue but no neoplastic lesion. Based on these findings, diagnosis of multilocular thymic cyst with follicular lymphoid hyperplasia was made. This is a rare case that preoperatively was difficult to diagnose.

    To evaluate the clinical and radiologic findings of atypical ductal hyperplasia (ADH) using mammography and ultrasonography, and to correlate the radiologic and histopathologic findings. Sixty-four pathologically proven lesions in 64 patients who were examined between March 2000 and March 2003 were the subject of this study. Mammography was performed in all 64 cases, and ultrasonography in 30. Two radiologists retrospectively evaluated the radiologic findings, classifying them as one of four types: mass, microcalcification, other finding, and no detected lesion. At mammography, masses were classified according to their shape, margin, and density and microcalcifications according to their shape and distribution. At ultrasonography, masses were evaluated in terms of their shape, margin, internal and posterior echotexture, ductal extension, and parallelism to skin. Geographic correlation between the radiologic and histopathologic findings was classified as direct, near direct, or remote correlation. Mammography demonstrated 37 cases of microcalcification (57.8%), 14 in which masses were present (21.9%), two in which there were other findings (3.1%), and 11 in which lesions were not detected (17.2%). The 'other finding' was ductectasia. Microcalcifications were round in 19 cases, pleomorphic heterogeneous in 16, and branching linear in one. The most common distribution of microcalcification was clustered (29 cases; 78.4%). Masses were oval or round in nine cases and irregular in three, and in seven cases their margin was ill-defined. In 13 cases, the density of the masses was equal to that of breast tissue. Ultrasonography showed that the masses were round or oval in 15 cases and irregular in 14, and that the margin was ill-defined in 16 cases and circumscribed in ten. In 19 cases, the echotexture of the masses was low, and in 20 cases, heterogeneous. Parallel orientation was seen in 25 cases, and ductal extension in 22. Category 4 was the most common final assessed BI

    Inflammation is the most prevalent and widespread histological finding in the human prostate, and associates with the development and progression of benign prostatic hyperplasia and prostate cancer. Several factors have been hypothesized to cause inflammation, yet the role each may play in the etiology of prostatic inflammation remains unclear. This study examined the possibility that the common protozoan parasite Toxoplasma gondii induces prostatic inflammation and reactive hyperplasia in a mouse model. Male mice were infected systemically with T. gondii parasites and prostatic inflammation was scored based on severity and focality of infiltrating leukocytes and epithelial hyperplasia. We characterized inflammatory cells with flow cytometry and the resulting epithelial proliferation with bromodeoxyuridine (BrdU) incorporation. We found that T. gondii infects the mouse prostate within the first 14 days of infection and can establish parasite cysts that persist for at least 60 days. T. gondii infection induces a substantial and chronic inflammatory reaction in the mouse prostate characterized by monocytic and lymphocytic inflammatory infiltrate. T. gondii-induced inflammation results in reactive hyperplasia, involving basal and luminal epithelial proliferation, and the exhibition of proliferative inflammatory microglandular hyperplasia in inflamed mouse prostates. This study identifies the common parasite T. gondii as a new trigger of prostatic inflammation, which we used to develop a novel mouse model of prostatic inflammation. This is the first report that T. gondii chronically encysts and induces chronic inflammation within the prostate of any species. Furthermore, T. gondii-induced prostatic inflammation persists and progresses without genetic manipulation in mice, offering a powerful new mouse model for the study of chronic prostatic inflammation and microglandular hyperplasia. © 2017 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Endometrial carcinoma is one of the most common gynecological malignancies in women. The diagnosis of the disease at early or premalignant stages is crucial for the patient's prognosis. To date, diagnosis and follow-up of endometrial carcinoma and hyperplasia require invasive procedures. Therefore, there is considerable demand for the identification of biomarkers to allow non-invasive detection of these conditions. Methods In this study, we performed a quantitative proteomics analysis on serum samples from simple endometrial hyperplasia, complex endometrial hyperplasia, atypical endometrial hyperplasia, and endometrial carcinoma patients, as well as healthy women. Serum samples were first depleted of high-abundance proteins, labeled with isobaric tags (iTRAQ™, and then analyzed via two-dimensional liquid chromatography and tandem mass spectrometry. Protein identification and quantitation information were acquired by comparing the mass spectrometry data against the International Protein Index Database using ProteinPilot software. Bioinformatics annotation of identified proteins was performed by searching against the PANTHER database. Results In total, 74 proteins were identified and quantified in serum samples from endometrial lesion patients and healthy women. Using a 1.6-fold change as the benchmark, 12 proteins showed significantly altered expression levels in at least one disease group compared with healthy women. Among them, 7 proteins were found, for the first time, to be differentially expressed in atypical endometrial hyperplasia. These proteins are orosomucoid 1, haptoglobin, SERPINC 1, alpha-1-antichymotrypsin, apolipoprotein A-IV, inter-alpha-trypsin inhibitor heavy chain H4, and histidine-rich glycoprotein. Conclusions The differentially expressed proteins we discovered in this study may serve as biomarkers in the diagnosis and follow-up of endometrial hyperplasia and endometrial carcinoma.

    Full Text Available Purpose. To apply massage therapy accompanied with stretching exercises for treatment of mammary gland hyperplasia, evaluate the clinical outcome in patients, and estimate the therapy as a novel treatment method for mammary hyperplasia. Methods. 28 adult female patients were selected and treated with massage therapy and stretching exercises focusing on skeleton muscles of chest, abdomen, and axilla. The mammary gland oxyhemoglobin (OxyHb and deoxyhemoglobin (DeoxyHb levels were detected before and after treatment after 15, 30, and 45 days. Results. In this cohort, pretreatment OxyHb (mean ± SD is 1.32±0.14 (medium-high, and DeoxyHb is 0.87±0.13 (normal. All patients were clinically diagnosed with benign mammary gland hyperplasia and mastitis. The posttreatment OxyHb levels are 1.23±0.09 (normal-medium, 15-day, 1.16±0.08 (normal, 30-day, and 1.05±0.04 (normal, 45-day, and DeoxyHb levels are 0.90±0.11 (normal, 15-day, 0.94±0.18 (normal, 30-day, and 0.98±0.12 (normal, 45-day. Patients were diagnosed with decreased hyperplasia 15 and 30 days after treatment and with no symptom of hyperplasia in mammary gland 45 days after treatment. Conclusion. Mammary gland hyperplasia is closely correlated with pathological changes of skeletal muscles and could be significantly improved by massage therapy and stretching exercises targeting neighboring skeletal muscles.

    The role of tumour inflammation and the dysplastic epithelial-stromal interactions on the nature of collagen fibres in the extracellular matrix of dysplastic epithelium is not fully understood. The present study was aimed to evaluate and compare the inflammation and pathological stromal collagen (loosely packed thin disorganized collagen) present in mild, moderate and severe epithelial dysplasias with that of inflammatory fibrous hyperplasias. The basement membrane intactness of epithelial dysplasias was also evaluated to determine if dysplastic epithelial mesenchymal interaction has any role in the integrity of stromal collagen in epithelial dysplasia. Oral epithelial dysplasias, inflammatory fibrous hyperplasia and normal oral mucosal samples were used for the study. Packing, thickness and orientation of collagen fibres in mild, moderate and severe grades of oral epithelial dysplasias (n = 24), inflammatory fibrous hyperplasia (n = 8) and normal oral mucosal samples (n = 8) were analysed based on the polarisation of collagen fibres in picrosirius red polarising stain under polarising microscope. All the grades of epithelial dysplasias showed greenish yellow birefringence confirming the presence of loosely arranged pathological collagen in the presence of moderate inflammation. All the cases of inflammatory fibrous hyperplasia showed red polarisation hue and moderate inflammation. A statistically significant difference was found in the packing and orientation of collagen when epithelial dysplasias and inflammatory fibrous hyperplasia were compared (P collagen even in mild epithelial dysplasia suggests that tumourigenic factors are released to connective tissue stroma much earlier than expected. Hence we suggest considering the integrity of extracellular matrix collagen, intactness of basement membrane and inflammation associated with dysplasia along with the anaplasia of epithelial cells in the microscopic assessment of dysplastic epithelium.

Methods: The apoptosis and expression of Ki-67 in benign prostatic hyperplasia (BPH) before and after irradiation 90 Sr- 90 Y were detected by transferase-mediated dUTP-biotin nick end labeling (TUNEL) method and immunohistochemical technique, respectively. Results: The proliferation index (PI) of BPH after 90 Sr- 90 Y irradiation was much lower than that before irradiation, but there was no significant change in apoptosis index (AI). Conclusion: Irradiation with 90 Sr- 90 Y could restrain cell proliferation of BPH, but could not induce apoptosis

    We report here on a case of localized lymphoid hyperplasia of the pancreas in a 70-year-old man which manifested as double lesions (uncinate process and tail) in the organ. The lesions were incidentally detected as hypoechoic lesions on ultrasonography and they appeared as delayed enhancing lesions on the contrast-enhanced dynamic CT and MRI. Total pancreatectomy was performed, because malignant tumor could not be excluded according to the preoperative imaging studies and the endoscopic ultrasound-guided biopsy failed. Pathology revealed localized lymphoid hyperplasia. The patient had an uneventful postoperative course. He has been alive for 18 months after surgery.

This model for health care delivery has been called the "medical home," a concept that was originally developed in pediatrics for the care of children with special needs. Patient and family-centered, comprehensive, interdisciplinary, culturally effective, and readily accessible health care delivery is desirable for the care of children with congenital adrenal hyperplasia. As children with congenital adrenal hyperplasia (CAH become adolescents and young adults, transfer of this health care delivery model to adult endocrinologists is appropriate.

    Ultrasonographic, computed tomographic, and angiographic abnormalities of nodular regenerative hyperplasia have been described in very few cases. We report here the case of a 50-year-old man with round, well-limited hypoechogenic lesions involving the two lobes of the liver, and hypervascular, poorly delineated angiographic lesions. Computed tomography and magnetic resonance of the liver were normal. Histological examination of large liver specimens provided by intraoperative biopsy allowed the diagnosis of nodular regenerative hyperplasia. Such a pseudo-tumoral ultrasonographic and angiographic pattern must be recognized in order to avoid diagnostic and therapeutic mistakes, especially since percutaneous liver biopsy usually fails to diagnose this disease.

    2013-09-01

    The Bangladesh government, nongovernmental organizations, donors, and advocacy groups have attempted various interventions to promote gender equality and reduce intimate partner violence (IPV) against women, but rigorous evaluations of these interventions are rare and few published studies have yet to show that any of them has had a substantial impact. This study presents qualitative evidence from four villages in central and northern Bangladesh drawn from 11 group discussions (6 with men, 5 with women), 16 open-ended interviews with men, and 62 women's life history narratives. The findings strongly suggest that IPV is declining in these villages as women's economic roles expand and they gain a stronger sense of their rights. Periodic surveys are recommended to measure trends in the incidence of IPV in settings where transitions in gender systems are under way. © 2013 The Population Council, Inc.

    In this article, we argue that past efforts to distinguish among types of intimate partner violence in general survey data have committed a critical error--using data on current spouses to develop operationalizations of intimate terrorism and situational couple violence. We use ex-spouse data from the National Violence Against Women Survey (NVAWS) to develop new operationalizations. We then demonstrate that NVAWS current spouse data contain little intimate terrorism; we argue that this is likely to be the case for all general surveys. In addition, the ex-spouse data confirm past findings regarding a variety of differences between intimate terrorism and situational couple violence, including those predicted by feminist theories.

    Full Text Available BACKGROUND: Suicide is the 10th leading cause of death in the United States. Furthermore, intimate partner problems are amid the top precipitating circumstances among suicide decedents. The aim of this study was to determine circumstantial associations of intimate partner problem-related suicides in suicide decedents in Kentucky. METHODS: All suicides that were reported to the Kentucky Violent Death Reporting System between 2005 and 2012 were eligible for this study. Multiple logistic regression was used to explore predictors (precipitating health-related problems, life stressors, and criminal/legal issues of intimate partner problem-related suicides. RESULTS: Of the 4,754 suicides, included in this study, approximately 17% had intimate partner problems prior to suicide. In the adjusted analysis, mental health issues, alcohol problems, history of suicides attempts, suicides precipitated by another crime, and other legal problems increased the odds of having an intimate partner-related suicide. However, having physical health problems, prior to the suicide, decreased the odds of intimate partner-related suicide. CONCLUSIONS: These results provide insight for the development of suicide interventions for individuals with intimate partner problems by targeting risk factors that are prevalent among this population. Moreover, these results may help marriage/relationship and/or family/divorce court representatives identify individuals with intimate partner problems more at risk for suicide and alleviate the influence these suicide risk factors have on individuals experiencing Intimate partner problems.

    Woman abuse varies across intimate relationship categories (e.g., marriage, divorce, separation). However, it is unclear whether relationship status variations in violence against women differ across urban, suburban, and rural areas. We test the hypothesis that rural females, regardless of their intimate partner relationship status, are at higher risk of intimate violence than their urban and suburban counterparts. Results indicate that marital status is an important aspect of the relationship between intimate victimization and geographic area and that rural divorced and separated females are victimized at rates exceeding their urban counterparts.

    Purpose Hemodialysis grafts fail because of venous neointimal hyperplasia formation caused by adventitial fibroblasts which have become myofibroblasts (α-smooth muscle actin positive cells) and migrate to the neointima. There is increased expression of hypoxia inducible factor-1 alpha (HIF-1α in venous neointimal hyperplasia formation in experimental animal model and clinical samples. We hypothesized that under hypoxic stimulus (HIF-1α fibroblasts will convert to myofibroblasts through a matrix metalloproteinase-2 (MMP-2) mediated pathway. Materials and methods Murine AKR-2B fibroblasts were made hypoxic or normoxic for 24, 48, and 72 hours. Protein expression for HIF-1α, α-smooth muscle actin, MMP-2, MMP-9, TIMP-1, and TIMP-2 was performed to determine the kinetic changes of these proteins. Immunostaining for α-smooth muscle actin, collagen, and fibronectin was performed. Results At all time points, there was significantly increased expression of HIF-1α in the hypoxic fibroblasts when compared to normoxic fibroblasts (P<0.05). There was significantly increased expression α-smooth muscle actin at all time points which peaked by 48 hours in hypoxic fibroblasts when compared to normoxic fibroblasts (P<0.05). There was a significant increase in the expression of active MMP-2 by 48-72 hours and a significant increase in tissue inhibitor of metalloproteinase-1 (TIMP-1) by 48-72 hours by hypoxic fibroblasts (P<0.05). By 72 hours, there was significant increase in TIMP-2 expression (P<0.05). Immunohistochemical analysis demonstrated increased expression for α-smooth muscle actin, collagen, and fibronectin as the length of hypoxia increased. Conclusions Under hypoxia, fibroblasts will convert to myofibroblasts through a MMP-2 mediated pathway which may provide insight into the mechanism of venous neointimal hyperplasia. PMID:20434368

    We tested the effects of a saw palmetto herbal blend in men with symptomatic benign prostatic hyperplasia (BPH) via a randomized, placebo controlled trial. We randomized 44 men 45 to 80 years old with symptomatic BPH into a trial of a saw palmetto herbal blend versus placebo. End points included routine clinical measures (symptom score, uroflowmetry and post-void residual urine volume), blood chemistry studies (prostate specific antigen, sex hormones and multiphasic analysis), prostate volumetrics by magnetic resonance imaging, and prostate biopsy for zonal tissue morphometry and semiquantitative histology studies. Saw palmetto herbal blend and placebo groups had improved clinical parameters with a slight advantage in the saw palmetto group (not statistically significant). Neither prostate specific antigen nor prostate volume changed from baseline. Prostate epithelial contraction was noted, especially in the transition zone, where percent epithelium decreased from 17.8% at baseline to 10.7% after 6 months of saw palmetto herbal blend (p saw palmetto herbal blend (p saw palmetto herbal blend. When the study was no longer blinded, 41 men elected to continue therapy in an open label extension. Saw palmetto herbal blend appears to be a safe, highly desirable option for men with moderately symptomatic BPH. The secondary outcome measures of clinical effect in our study were only slightly better for saw palmetto herbal blend than placebo (not statistically significant). However, saw palmetto herbal blend therapy was associated with epithelial contraction, especially in the transition zone (p <0.01), indicating a possible mechanism of action underlying the clinical significance detected in other studies.

    Early studies suggested macrophages might play roles in inflammation-associated benign prostatic hyperplasia (BPH) development, yet the underlying mechanisms remain unclear. Here we first showed that CD68(+) macrophages were identified in both epithelium and the stromal area of human BPH tissues. We then established an in vitro co-culture model with prostate epithelial and macrophage cell lines to study the potential impacts of infiltrating macrophages in the BPH development and found that co-culturing prostate epithelial cells with macrophages promoted migration of macrophages. In a three-dimensional culture system, the sphere diameter of BPH-1 prostate cells was significantly increased during coculture with THP-1 macrophage cells. Mechanism dissection suggested that expression levels of epithelial-mesenchymal transition (EMT) markers, such as N-cadherin, Snail, and TGF-β2, were increased, and administration of anti-TGF-β2 neutralizing antibody during co-culture suppressed the EMT and THP-1-mediated growth of BPH-1 cells, suggesting THP-1 might go through EMT to influence the BPH development and progression. Importantly, we found that modulation of androgen receptor (AR) in BPH-1 and mPrE cells significantly increased THP-1 and RAW264.7 cell migration, respectively, and enhanced expression levels of EMT markers, suggesting that AR in prostate epithelial cells might play a role in promoting macrophage-mediated EMT in prostate epithelial cells. Silencing AR function via an AR degradation enhancer, ASC-J9, decreased the macrophage migration to BPH-1 cells and suppressed EMT marker expression. Together, these results provide the first evidence to demonstrate that prostate epithelial AR function is important for macrophage-mediated EMT and proliferation of prostate epithelial cells, which represents a previously unrecognized role of AR in the cross-talk between macrophages and prostate epithelial cells. These results may provide new insights for a new therapeutic

    Full Text Available Abstract Background Inhalation of particles aggravates respiratory symptoms including mucus hypersecretion in patients with chronic airway disease and induces goblet cell hyperplasia (GCH in experimental animal models. However, the underlying mechanisms remain poorly understood. Methods To understand this, the numbers of goblet cells, Muc5ac (+ expressing epithelial cells and IL-13 expressing mast cells were measured in the trachea of sham or TiO2 particles – treated rats using periodic acid-Schiff, toluidine blue and immunohistochemical staining. RT-PCR for Muc-1, 2 and 5ac gene transcripts was done using RNA extracted from the trachea. Differential cell count and IL-13 levels were measured in bronchoalveolar lavage (BAL fluid. In pretreatment groups, cyclophosphamide (CPA or dexamethasone (DEX was given before instillation of TiO2. TiO2 treatment markedly increased Muc5ac mRNA expression, and Muc5ac (+ or PAS (+ epithelial cells 48 h following treatment. Results The concentration of IL-13 in BAL fluids was higher in TiO2 treated – rats when compared to those in sham rats (p 2 treated – rats (p 0.05. In contrast, pretreatment with dexamethasone (DEX diminished the percentage of PAS (+ cells and the levels of IL-13 (p 2 treatment increased the IL-13 (+ mast cells (p 0.05. In addition there were significant correlations of IL-13 (+ rate of mast cells in the trachea with IL-13 concentration in BAL fluid (p 2 treated rats (p Conclusion In conclusion, TiO2 instillation induces GCH and Muc5ac expression, and this process may be associated with increased production of IL-13 by mast cells.

    Background: Intimate partner violence (IPV) is commonly bidirectional with both partners perpetrating and being victims of aggressive behaviors. In these couples, family dysfunction is reported across a broad range of family functions: communication, intimacy, problem solving, expression or control of anger, and designation of relationship roles. This study reports on the perceived family functioning of suicidal inpatients. Method: In this descriptive, cross-sectional study of adult suicidal inpatients, participants completed assessments of recent IPV and family functioning. Recruited patients were between 18 and 65 years of age and English fluent, had suicidal ideation, and were living with an intimate partner for at least the past 6 months. Intimate partner violence was assessed using the Conflict Tactics Scale-Revised, and family functioning was measured using the McMaster Family Assessment Device. The study was conducted from August 2004 through February 2005. Results: In 110 inpatients with suicidal ideation and IPV, family functioning was perceived as poor across many domains, although patients did report family strengths. Gender differences were not found in the overall prevalence of IPV, but when the sample was divided into good and poor family functioning, women with poorer family functioning reported more psychological abuse by a partner. For both genders, physical and psychological victimization was associated with poorer family functioning. Conclusion: Among psychiatric inpatients with suicidal ideation, IPV occurred in relationships characterized by general dysfunction. Poorer general family functioning was associated with the perception of victimization for both genders. The high prevalence of bidirectional IPV highlights the need for the development of couples treatment for this population of suicidal psychiatric inpatients. PMID:18185819

  5. The INTIMATE event stratigraphy of the last glacial period

    2015-04-01

    The North Atlantic INTIMATE (INtegration of Ice-core, MArine and TErrestrial records) group has previously recommended an Event Stratigraphy approach for the synchronisation of records of the Last Termination using the Greenland ice core records as the regional stratotypes. A key element of these protocols has been the formal definition of numbered Greenland Stadials (GS) and Greenland Interstadials (GI) within the past glacial period as the Greenland expressions of the characteristic Dansgaard-Oeschger events that represent cold and warm phases of the North Atlantic region, respectively. Using a recent synchronization of the NGRIP, GRIP, and GISP2 ice cores that allows the parallel analysis of all three records on a common time scale, we here present an extension of the GS/GI stratigraphic template to the entire glacial period. In addition to the well-known sequence of Dansgaard-Oeschger events that were first defined and numbered in the ice core records more than two decades ago, a number of short-lived climatic oscillations have been identified in the three synchronized records. Some of these events have been observed in other studies, but we here propose a consistent scheme for discriminating and naming all the significant climatic events of the last glacial period that are represented in the Greenland ice cores. In addition to presenting the updated event stratigraphy, we make a series of recommendations on how to refer to these periods in a way that promotes unambiguous comparison and correlation between different proxy records, providing a more secure basis for investigating the dynamics and fundamental causes of these climatic perturbations. The work presented is a part of a newly published paper in an INTIMATE special issue of Quaternary Science Reviews: Rasmussen et al., 'A stratigraphic framework for abrupt climatic changes during the Last Glacial period based on three synchronized Greenland ice-core records: refining and extending the INTIMATE event

    In this article, I examine how gender-based violence has been framed in Spanish legal, social and cultural discourses since the fall of the dictatorship. Prior to 1997, far less attention was paid to intimate partner abuse than in most other democratic states. In the last ten years, this situation has been reversed. There has been heavy media coverage, and new legislation that adopts an holistic approach to the problem. I will attempt to place these changes in context and to provide extensive bibliographical information for those readers seeking information in more specialised fields.

    When spouses received feedback that disconfirmed their impressions of their partners, they attempted to undermine that feedback during subsequent interactions with these partners. Such partner verification activities occurred whether partners construed the feedback as overly favorable or overly unfavorable. Furthermore, because spouses tended to see their partners as their partners saw themselves, their efforts to restore their impressions of partners often worked hand-in-hand with partners' efforts to verify their own views. Finally, support for self-verification theory emerged in that participants were more intimate with spouses who verified their self-views, whether their self-views happened to be positive or negative.

    Persistent infection with high-risk human papillomaviruses (HPV) causes epithelial hyperplasia that can progress to cancer and is thought to depend on immunosuppressive mechanisms that prevent viral clearance by the host. IL-17 is a cytokine with diverse functions in host defense and in the pathology of autoimmune disorders, chronic inflammatory diseases, and cancer. We analyzed biopsies from patients with HPV-associated cervical intraepithelial neoplasia grade 2/3 and murine skin displaying HPV16 E7 protein-induced epithelial hyperplasia, which closely models hyperplasia in chronic HPV lesions. Expression of IL-17 and IL-23, a major inducer of IL-17, was elevated in both human HPV-infected and murine E7-expressing lesions. Using a skin-grafting model, we demonstrated that IL-17 in HPV16 E7 transgenic skin grafts inhibited effective host immune responses against the graft. IL-17 was produced by CD3(+) T cells, predominantly CD4(+) T cells in human, and CD4(+) and γδ T cells in mouse hyperplastic lesions. IL-23 and IL-1β, but not IL-18, induced IL-17 production in E7 transgenic skin. Together, these findings demonstrate an immunosuppressive role for IL-17 in HPV-associated epithelial hyperplasia and suggest that blocking IL-17 in persistent viral infection may promote antiviral immunity and prevent progression to cancer.

    The aim of the present study is to determine the prevalence of endometrial premalignancies in women diagnosed with epithelial ovarian cancer (EOC). Endometrial and ovarian specimens of 186 patients with EOC were retrospectively selected using the nationwide pathology network and registry, and sections were comprehensively reviewed: 136 (73%) serous, 19 (10%) endometrioid, 15 (8%) mucinous, seven (4%) clear cell, and nine (5%) undifferentiated. Immunohistochemical phenotypes were compared for patients with serous EOC with concurrent endometrial pathology. In 31%, endometrial (pre)malignancy was found: carcinoma in 3%, endometrial intraepithelial carcinoma (EIC) in 4%, and atypical hyperplasia in 24%. Atypical hyperplasia was found in 47% of endometrioid EOCs but in 7% to 33% of other subtypes. Body mass index was higher concurrent to atypical hyperplasia (P=.001). Serous EOC and EIC immunophenotypes were comparable, whereas atypical hyperplasia was expressed differently. Apart from synchronous endometrial carcinoma, endometrial premalignancies should be taken into account when determining optimal treatment for women diagnosed with EOC.

    Multifocal epithelial hyperplasia is an uncommon disease of the oral mucosa caused by the human papilloma virus. To study the clinical and pathological findings of multifocal epithelial hyperplasia detected during an oral examination of 343 Mexican Nahuatl children from a single primary school in El Paso de Cupilco, Mexico. A thorough oral examination was performed in all children and clinical data (age, gender, location and number of lesions) were documented and analyzed. Multifocal epithelial hyperplasia was diagnosed in 110 of the 343 children (32.3%). The ages of the children varied from 5 to 15 years, and of these, 56.3% were girls. The lesions were asymptomatic, 0.2 to 3.0 cm in diameter, soft, round to oval, smooth surfaced, sessile papulonodules, similar in colour to that of the surrounding mucosa. The lesions were commonly seen on the buccal mucosa and tongue, and most affected children (85%) had less than 5 lesions. Children in the 7 to 10 years age group were most often affected. Human papillomavirus typing was not done owing to a lack of facilities. There is a high incidence of multifocal epithelial hyperplasia in Nahuatl children with a predilection for females.

    Full Text Available Reactive hyperplasia can occur in any part of the body but of concern is occurrence adjacent to certain neoplasm such as cutaneous fibrous histiocytoma, granular cell tumor, spitz nevus and melanoma. Ocular reactive epithelial hyperplasia is not as common as ocular reactive lymphoid hyperplasia. This is the first reported case in our environment. The patient was concerned about his cosmetic appearance, comments of friends and fear of eye problem in future. We report the case of a 32 year old patient with painless, progressive swelling of the conjunctiva following stone injury to the eye while on a bike 5 years earlier. A traumatic conjunctival cyst to rule out melanoma was the initial diagnosis. We therefore, managed the case by excision biopsy and histology report was in keeping with conjunctival reactive epithelial hyperplasia. One year after removal, he was free of any swelling and had no complaints. Conclusion: Excision biopsy is effective and it will assist in ruling out neoplasm and taking care of the patient’s cosmetic problem.

    Pseudoangiomatous stromal hyperplasia is a benign proliferative lesion of the mammary stroma that rarely presents as a localized mass. Pseudoangiomatous stromal hyperplasia is characterized by a dense, collagenous proliferation of the mammary stroma, associated with capillary-like spaces. Pseudoangiomatous stromal hyperplasia can be mistaken with fibroadenoma on radiological examination or with low-grade angiosarcoma on histological examination. Its main importance is its distinction from angiosarcoma. The presented case was a 40-year-old woman who was admitted with a rapidly growing breast tumor. Physical examination revealed an elastic-firm, well-defined, mobile and painless mass in her right breast. Mammograms revealed a 6.7 x 3.7 cm, lobulated, well-circumscribed mass in her right breast but no calcification. Sonographic examination showed a well-defined and homogenous mass, not including any cyst. Based on these findings, a provisional diagnosis of fibroadenoma was made. Considering the rapid growth history of the mass, tumor excision was performed. The excised tumor was well demarcated and had a smooth external surface. Histological examination revealed the tumor to be composed of markedly increased fibrous stroma and scattered epithelial components (cystic dilatation of the ducts, blunt duct adenosis). The fibrous stroma contained numerous anastomosing slit-like spaces. Isolated spindle cells appeared intermittently at the margins of the spaces resembled endothelial cells. Immunohistochemical staining showed that the spindle cells were positive for CD34 and negative for Factor VIII-related antigen. The lesion was diagnosed as nodular pseudoangiomatous stromal hyperplasia.

    Full Text Available Phosphatase and tensin homolog (PTEN is a protein that acts as a tumor suppressor by dephosphorylating the lipid second messenger phosphatidylinositol 3,4,5-trisphosphate. Loss of PTEN function has been implicated in the pathogenesis of a number of different tumors, particularly endometrial carcinoma (ECa. ECa is the most common neoplasia of the female genital tract. Our study evaluates an association between the morphological appearance of endometrial hyperplasia and endometrial carcinoma and the degree of PTEN alterations. A total of 45 endometrial biopsies from Slovak women were included in present study. Formalin-fixed and paraffin-embedded tissue samples with simple hyperplasia (3, complex hyperplasia (5, atypical complex hyperplasia (7, endometrioid carcinomas G1 (20 and G3 (5, and serous carcinoma (5 were evaluated for the presence of mutations in coding regions of PTEN gene, the most frequently mutated tumor suppressor gene in endometrial carcinoma. 75% of the detected mutations were clustered in exons 5 and 8. Out of the 39 mutations detected in 24 cases, 20 were frameshifts and 19 were nonsense, missense, or silent mutations. Some specimens harboured more than one mutation. The results of current study on Slovak women were compared to a previous study performed on Polish population. The two sets of results were similar.

    Purpose: To evaluate parathyroid substration scintigraphy with Tc99m-pertechnetate-Tc99m-MIBI, for detection of parathyroid adenomas or hyperplasia in patients with hyperparathyroidism. Materials and methods: Thirty patients were studied by Tc99m-pertechnetate-Tc99m-MIBI scintigraphy, 24 with primary hyperparathyroidism, 2 with hypo echogenic nodular image behind the thyroid gland, 1 with bone fracture history, 1 with hypophosphataemia and 2 with secondary hyperparathyroidism. The initial image was made with pertechnetate, the next one and the late (2-3 hs) with Tc99m-MIBI, making digital substration with the first image. Six patients were excluded (difficult follow-up n=5, death n=1). Results: The final 24 patients series showed: 10 positive and 12 negative for adenomas; 1 positive and 1 negative for hyperplasia. The correlation between the scintigraphic study and the clinical, biochemical and anatomicopathological data, showed a high sensitivity (90%), and specificity (92%), for parathyroid adenomas and/or hyperplasia. Conclusions: The Tc99m-pertechnetate-Tc99m-MIBI shows high sensitivity and high specificity for the detection of adenomas and hyperplasia in patient with hyperparathyroidism. (author)

    The distinction between atypical hyperplasia and carcinoma in situ in breast lesions can be difficult. The identification of myoepithelial cell layers may be helpful in establishing a diagnosis of proliferative breast disease vs. intraepithelial neoplasia. We reviewed pathologic material on 20 cases of atypical hyperplasia and 29 cases of carcinoma in situ. Immunohistochemical stains were employed against muscle-specific actin, S-100 protein, and cytokeratin to identify myoepithelial cells and to recognize different staining patterns. In atypical hyperplasia, muscle-specific actin staining identified myoepithelial cells in fine branching fibrovascular layers or as scattered cells between other proliferating cells. This pattern was absent in carcinoma in situ. S-100 protein showed more positive staining in atypical hyperplasia than in carcinoma in situ with patterns distinct from muscle-specific actin. Immunostaining for cytokeratin demonstrated distinctly different patterns between the two lesions. This study suggests that muscle-specific actin, S-100 protein, and cytokeratin in combination may assist in distinguishing proliferative breast disease with atypia from carcinoma in situ.

Another objective was to investigate the clinical effect and safety of mega dose of tamsulosin in the treatment of benign prostatic hyperplasia in combination with overactive bladder. One hundred and twenty-four patients who were admitted to the Dept. of Urology at Binzhou People's Hospital, , China with confirmed benign prostatic hyperplasia (BPH) with overactive bladder were randomly divided into two groups. Sixty-two patients in the control group were treated with tamsulosin, while sixty-two patients in the observation group were treated with tamsulosin in combination with solifenacin. The treatment of both groups lasted for 12 weeks. The effect and adverse reaction were compared between the two groups. The international prostate symptom score (IPSS), quality of life (QOL), and overactive bladder symptom score (OABSS), Q max , pulmonary vascular resistance (PVR), daytime urination frequency, urgent urination frequency, urge urinary incontinence frequency and night urinary frequency of both groups improved after treatment, and the difference had statistical significance (P0.05). Treating benign prostatic hyperplasia in combination with overactive bladder with tamsulosin in combination with solifenacin is more effective than tamsulosin, without significantly increasing adverse reactions. Thus the therapy is worth clinical promotion.

    To evaluate the ultrasound (US) findings that can help differentiate lymphoid hyperplasia in the appendix from acute appendicitis. A total of 1230 patients (below 20 years old) suspected of having appendicitis received an appendectomy between November, 1999, and March, 2008, with US findings in 27 patients with pathologically proven lymphoid hyperplasia of the appendix. Of 167 patients that received an appendectomy from January, 2007, to December, 2007, 52 patients with acute appendicitis were retrospectively reviewed as a control group. Retrospective review of US images was performed by two radiologists who were blinded to the pathologic results. The review was based on 12 ultrasonographic criteria derived from reports on the diagnostic findings of the appendicitis. Compared with acute appendicitis, lymphoid hyperplasia in appendix had a smaller diameter (7.14±1.22 mm vs 9.37±1.80 mm, p < 0.001) and less wall thickening(1.38±0.36 mm vs 1.74 ± 0.56 mm, p =0.001). Periappendicular inflammation (p < 0.001), intraluminal air (p = 0.006), round shape in transverse scan (p = 0.002),increased blood flow on color Doppler US (p = 0.03) were also different.

    National estimates suggest intimate partner violence (IPV) rates are equal or higher among lesbian, bisexual, or questioning (LBQ)-identified women than heterosexual-identified women. Women veterans are a population at high risk for IPV, yet the occurrence of lifetime and past-year IPV experiences by sexual orientation have not been examined in this population. Lifetime and past-year IPV experiences and current IPV-related posttraumatic stress disorder (PTSD) symptoms were assessed with validated screening measures as part of a 2014 web-based national survey of women veterans. Among 403 respondents, 9.7% (n = 39) identified as LBQ, and 90.3% (n = 364) identified as heterosexual. When controlling for age, LBQ-identified women veterans were significantly more likely to report lifetime sexual and physical IPV and lifetime intimate partner stalking. In the past year, LBQ-identified veterans were twice as likely to endorse emotional mistreatment and physical IPV, and three times more likely to endorse sexual IPV, than were heterosexual-identified women veterans. However, sexual orientation was unrelated to IPV-related PTSD symptoms, when controlling for age, race, and number IPV forms experienced. IPV is prevalent among LBQ-identified women veterans, suggesting the need to understand the potentially unique contextual factors and health-care needs of this group.

    Early studies examining parenting in the setting of intimate partner violence (IPV) often focus on abuse by the IPV perpetrator or effects of long term exposure. This review addresses how intimate partner violence impacts victim parenting. Seven databases were searched for the time period 1970-2015. Included were comparative studies involving children 11 years or younger. Quality ranking was based on: confirmation of victim status, consideration of co-perpetration, heterogeneity of the population, and standardization of measurements. Of 13,038 studies reviewed, 33 included studies showed that victimization is associated with negative parenting practices. Based on data presented within individual studies, 21 studies were eligible for meta-analysis which demonstrated modest effect sizes with high levels of heterogeneity. There was a negative correlation between IPV and positive parenting (r = -0.08; 95% CI: -.12, - .04); positive correlation between IPV and physical aggression (r = .17; 95% CI: .11, .23) and neglect (r = .12; 95% CI: .01, .23); and a trend toward positive correlation between IPV and psychological aggression (r = .23; 95% CI: -.94, .47). A synthesis of studies unsuitable for meta-analysis reinforced these findings. The review demonstrated ongoing methodological issues with extant literature. Copyright © 2018 Elsevier Ltd.

    Research on gender roles suggests that men who strongly adhere to traditional masculine gender norms are at increased risk for the perpetration of violent and abusive acts toward their female intimate partners. Yet, gender norms alone fail to provide a comprehensive explanation of the multifaceted construct of intimate partner violence (IPV) and there is theoretical reason to suspect that men who fail to conform to masculine roles may equally be at risk for IPV. In the present study, we assessed effect of masculine discrepancy stress , a form of distress arising from perceived failure to conform to socially-prescribed masculine gender role norms, on IPV. Six-hundred men completed online surveys assessing their experience of discrepancy stress, masculine gender role norms, and history of IPV. Results indicated that masculine discrepancy stress significantly predicted men's historical perpetration of IPV independent of other masculinity related variables. Findings are discussed in terms of potential distress engendered by masculine socialization as well as putative implications of gender role discrepancy stress for understanding and intervening in partner violence perpetrated by men.

    We report the case of a 59-year-old female with progressive bilateral painful swelling of the thighs. MRI revealed multiple intramuscular necrotic masses with similar morphologic patterns. Whole-body CT and 18-FDG PET-CT scans demonstrated additional hypermetabolic muscular masses and a lobulated lesion within the left atrial cavity. As biopsy of a muscular mass was compatible with a poorly differentiated sarcoma with MDM2 oncogene amplification, two diagnoses were discussed: a dedifferentiated liposarcoma with muscle and heart metastases or a primary cardiac sarcoma, mainly a cardiac intimal sarcoma, with muscular metastases, which was finally confirmed by array-comparative genomic hybridization (aCGH) in a sarcoma reference center. This case emphasizes the potential for intimal sarcoma to disseminate in skeletal muscle prior to any other organ and the need for a genomic approach in addition to classical radiopathologic analyses to distinguish primary from secondary locations facing simultaneous tumors of the heart and skeletal muscles with MDM2 amplification.

    Intimate partner violence (IPV) is a significant global public health concern, affecting 5.3 million US individuals annually. An estimated 1 in 3 women globally are abused by an intimate partner in their lifetime, and the effects carry over into the workplace. This article examines employers' perceptions of IPV in the workplace, targeting supervisors of Latina employees. Fourteen employers and supervisors of small service-sector companies in Oregon were interviewed using semi-structured interviews. Interpretive description was used to identify themes. These qualitative interviews preceded and helped to formulate a larger workplace intervention study. THE FOLLOWING THEMES WERE FOUND AND ARE DETAILED: (1) factors associated with recognizing IPV in the workplace, (2) effects of IPV on the work environment and (3) supervisors' responses to IPV-active vs. passive involvement. Also, supervisors' suggestions for addressing IPV in the workplace are summarized. These findings demonstrate the need for more IPV-related resources in the workplace to be available to supervisors as well as survivors and their coworkers. The needs of supervisors and workplaces vary by site, demonstrating the need for tailored interventions, and culturally appropriate workplace interventions are needed for Latinas and other racially and ethnically diverse populations.

    In spite of enough prevalence data on Intimate Partner Violence (IPV) during pregnancy from many countries, there are still some regions such as the Middle East with relatively limited data. The purpose of research was to investigate the magnitude of IPV during pregnancy in an Iranian community. Thirty hundred fifty women during their postpartum period were invited to participate in a cross-sectional population-based study, but 10.6% of them refused participation. The data was compiled using the Abuse Assessment Screen questionnaire. Of the 313 women, 55.9% reported violence during pregnancy. All types of violence were detected in victims during pregnancy, including psychological violence (43.5%), physical violence (10.2%), and sexual violence (17.2%). Intimate partner violence during pregnancy was significantly associated with lower education of the husbands (PR 1.64; 95% CI 1.15-2.36), un-employment of the husbands (PR 1.36; 95% CI 1.12-1.64), marriage duration of 5-9 years (PR 0.95; 95% CI 0.74-1.20) and gravidity of two (PR 0.80; 95% CI 0.59-1.08). The reported prevalence of IPV before and during pregnancy in this sample is substantially higher than estimates of exposure to violence in other parts of the globe, even the East Mediterranean region which has the highest prevalence estimation in the globe.

  3. Intimate Surveillance: Normalizing Parental Monitoring and Mediation of Infants Online

    Directory of Open Access Journals (Sweden)

    2017-05-01

    Full Text Available Parents are increasingly sharing information about infants online in various forms and capacities. To more meaningfully understand the way parents decide what to share about young people and the way those decisions are being shaped, this article focuses on two overlapping areas: parental monitoring of babies and infants through the example of wearable technologies and parental mediation through the example of the public sharing practices of celebrity and influencer parents. The article begins by contextualizing these parental practices within the literature on surveillance, with particular attention to online surveillance and the increasing importance of affect. It then gives a brief overview of work on pregnancy mediation, monitoring on social media, and via pregnancy apps, which is the obvious precursor to examining parental sharing and monitoring practices regarding babies and infants. The examples of parental monitoring and parental mediation will then build on the idea of “intimate surveillance” which entails close and seemingly invasive monitoring by parents. Parental monitoring and mediation contribute to the normalization of intimate surveillance to the extent that surveillance is (resituated as a necessary culture of care. The choice to not survey infants is thus positioned, worryingly, as a failure of parenting.

    Previous research has consistently found that low SES is associated with higher levels of both intimate partner violence (IPV) and sexual violence (SV) victimization. Though associated with poverty, two indicators of economic insecurity, food and housing insecurity, have been identified as conceptually distinct social determinants of health. This study examined the relationship between food and housing insecurity experienced in the preceding 12 months and IPV and SV victimization experienced in the preceding 12 months, after controlling for SES and other demographic variables. Data were from the 2010 National Intimate Partner and Sexual Violence Survey, a nationally representative telephone survey of U.S. adults. In 2016, multivariate logistic regression modeling was used to examine the association between food and housing insecurity and multiple forms of IPV and SV victimization. Robust associations were found between food and housing insecurity experienced in the preceding 12 months and IPV and SV experienced in the preceding 12 months, for women and men, even after controlling for age, family income, race/ethnicity, education, and marital status. Food and housing insecurity may be important considerations for the prevention of SV and IPV or the reductions of their consequences, although future research is needed to disentangle the direction of the association. Strategies aimed at buffering economic insecurity may reduce vulnerability to IPV and SV victimization. Copyright © 2017. Published by Elsevier Inc.

    Violence against women (VAW) is a global social issue affecting health, social, and legal systems. VAW contributes to the inequities with respect to the social determinants of health that many women face today. The onus on self-care in the face of violence remains almost singularly with the victims. Access to information and services in support of women's health and safety is fundamental. However, research gaps exist regarding how women access health information across all stages of an abusive intimate relationship. Given the ubiquity of online access to information, the purpose of this scoping review was to provide an overview of online interventions available to women within the context of intimate partner violence (IPV). Research literature published between 2000 and 2016, inclusive, was reviewed: 11 interventions were identified. Findings suggest that online interventions focused on the act of leaving with less emphasis on the experiences that occur after a woman has left the relationship. In addition, the online interventions concentrated on the individual capacity of the survivor to leave an abusive relationship and demonstrated limited understanding of IPV in relation to the broader social-contextual factors. Findings from this research highlight information gaps for women who require significant support after leaving an abusive relationship.

    2010-02-01

    A 1-year-old sexually intact female domestic shorthair cat was evaluated because of an 8-week history of pronounced mammary gland hyperplasia that had progressed to mastitis and abscessation of the mammary glands since parturition 7 days earlier. The cat was anorectic, was febrile, and had signs of discomfort. Its kittens were weak and appeared to have difficulty nursing. Physical examination revealed pyrexia, mastitis with abscessation in the 6 caudal mammary glands, skin ulceration over the nipples, and areas of skin necrosis over the abscessed mammary glands. A CBC revealed nonregenerative anemia and leukocytosis with a left shift (2.160 x 10(9) band cells/L) and toxic changes. Mastitis and incipient septicemia were considered the most likely causes. The history of mammary gland hyperplasia since the second week of pregnancy suggested a diagnosis of fibroadenomatous hyperplasia that predisposed the cat to subsequent mastitis. Surgical drainage of the abscessed mammary glands, debridement of necrotic skin, and placement of a Penrose drain resulted in rapid improvement in clinical status. Broad-spectrum antimicrobial treatment (amoxicillin-clavulanic acid) was prescribed, and the cat was discharged from the hospital. Mastitis and fibroadenomatous mammary gland hyperplasia resolved rapidly afterward. Management of abscessed mammary glands through surgical drainage and drain placement is an option for treatment of cats with complications of fibroadenomatous hyperplasia. In the cat of this report, the treatment approach resulted in rapid resolution of mastitis, was less invasive than mastectomy, and avoided the potential complications of treatment with a progesterone-receptor antagonist.

    Benign prostatic hyperplasia is a common disease in over 50 years-old men consisting in uncontrolled and benign growth of prostatic gland that leads to lower urinary tract symptoms. The etiology of benign prostatic hyperplasia is multifactoral involving the increased conversion of testosterone in dihydrotestosterone by the prostatic 5{alpha}-reductase action, which brought about events that encourage the prostate growth (static component) and the increase of the bladder and prostate smooth muscle tone (dynamic component) regulated by the a{alpha}{sub 1} -adrenoceptors (ADR). The pharmacological treatment of the benign prostatic hyperplasia includes the prostatic 5a{alpha}-reductase inhibitors, the a{alpha}{sub 1}-adrenoreceptor blockers, their combined therapy and the phytotherapy. This paper was aimed at presenting the most relevant aspects of the pharmacology of drugs used for treating the benign prostatic hyperplasia, and providing elements to analyze their efficacy, safety and tolerability. To this end, a review was made of the different drugs for the treatment of this pathology and they were grouped according to their mechanism of action. Natural products were included as lipid extracts from Serenoa repens and Pygeum africanum as well as D-004, a lipid extract from Roystonea regia fruits, with proved beneficial effects on the main etiological factors of benign prostatic hyperplasia. D-004 is a prostatic 5a-reductase inhibitor, an a{alpha}{sub 1}-adrenoceptor antagonist, a{alpha} 5-lipooxygenase inhibitor and has antioxidant action, all of which reveals a multifactoral mechanism. The results achieved till now indicate that D-004 is a safe and well-tolerated product

    Full Text Available Objective: We evaluated the correlation between benign prostate hyperplasia (BPH measures and diabetes mellitus in men with benign prostate hyperplasia in a prospective study. Materials and methods: Between 2008-2012, 100 diabetic and 200 non diabetic patients undergoing surgery due to benign prostate hyperplasia were enrolled in the study. The parameters evaluated for each patients included prostate volume, fasting blood glucose, HbA1c, total testosterone, total prostatic specific antigen (T-PSA, triglicerides, total cholesterol and body mass index (BMI. A questionnaire including international prostate symptom score (IPSS was sdministered and uroflow test measuring the peak urinary flow rate was performed to appreciate the complaints of the patients objectively. Results: Diabetic patients are more likely to have larger prostate volume. The symptom score evaluated by IPSS and post micturition residual volume were also significantly higher in diabetic groups. The other statistically significant different parameter between two groups was total testosterone that diabetic patients tend to have lower levels. Diabetic counterparts were established to have higher BMI. No statistically significant differentiation was observed about trigliceryde and total cholesterol levels and uroflow rates. Conclusions: Our study suggests a positive correlation between high prostate volume and diagnosis of diabetes mellitus in patients with benign prostatic hyperplasia. We also observed a positive correlation between symptom scores and post micturion residual volumes and diagnosis of diabetes mellitus suggesting that the presence of diabetes is related to both static and dynamic components of benign prostate hyperplasia. Additionally testosterone levels were lower in diabetic patients. Further studies need to confirm these relationship in a larger population.

    Endometrial cancer is a prevalent cancer, and its metastasis causes low survival rate. This study aims to utilize DNA methylation data to investigate the mechanism of the development and metastasis of endometrial cancer. Methylation profiling data were down-loaded from Gene Expression Omnibus, including 8 hyperplasias, 33 primary and 53 metastatic endometrial cancers. COHCAP package and annotation files were utilized to identify differentially methylated genes (DMGs) and CpG islands between the three different endometrial diseases. STRING database and Cytoscape were used to analyze and visualize protein-protein interactions (PPIs) between DMGs. CytoNCA plugin was utilized to identify key nodes in PPI network. A total of 610, 1076, and 501 DMGs were identified between primary endometrial cancer and hyperplasia, metastatic endometrial cancer and hyperplasia, as well as metastatic and primary endometrial cancers, respectively. For the three DMG sets, 53 common hypermethylated DMGs (e.g. PAX6 and INSR) and 6 common hypomethylated DMGs (e.g. PRDM8, KLHL14, and DUSP6) were found. For primary-hyperplasia DMG set and metastasis-hyperplasia DMG set, 527 common DMGs were found. For these common DMGs, a PPI network involving 692 PPIs was constructed. For DMGs between metastatic and primary endometrial cancers, a PPI network involving 673 PPIs was established, with PAX6 and INSR in the top 20 DMGs in both networks. PRDM8, KLHL14, and DUSP6 had hypomethylated CpG islands. DMGs comparison, PPI network analysis, and analysis of differentially methylated CpG islands indicated that PAX6, INSR, PRDM8, KLHL14, and DUSP6 might participate in the development and metastasis of endometrial cancer.

    Benign prostatic hyperplasia creates significant expenses for the Medicare program. We determined expenditure trends for benign prostatic hyperplasia evaluative testing after urologist consultation and placed these trends in the context of overall Medicare expenditures. Using a 5% national sample of Medicare beneficiaries from 2000 to 2007 we developed a cohort of 40,253 with claims for new visits to urologists for diagnoses consistent with symptomatic benign prostatic hyperplasia. We assessed trends in initial inflation and geography adjusted expenditures within 12 months of diagnosis by evaluative test categories derived from the 2003 American Urological Association guideline on the management of benign prostatic hyperplasia. Using governmental reports on Medicare expenditure trends for benign prostatic hyperplasia we compared expenditures to overall and imaging specific Medicare expenditures. Comparisons were assessed by the Z-test and regression analysis for linear trends, as appropriate. Between 2000 and 2007 inflation adjusted total Medicare expenditures per patient for the initial evaluation of patients with benign prostatic hyperplasia seen by urologists increased from $255.44 to $343.98 (p inflation adjusted expenditures increased for benign prostatic hyperplasia related evaluations. This growth was slower than the overall growth in Medicare expenditures. The increase in BPH related imaging expenditures was restrained compared to that of the Medicare program as a whole.

    In a particular way, the HIV pandemic exposes the prevailing gender relations and the definitions of male and female gender roles, both in intimate relationships and in the wider society. The HIV pandemic reveals the contradictions between women's legal rights and the persistence of women's cultural and sexual subordination. It reflects the impact of poverty, gender roles, culture and religion. Although HIV and AIDS cuts across class, South African rural black women's infection risk seems particularly high since they suffer notably from subordination and socio-economic hardships. Negotiating safer sex in marriage or intimate partnerships is very difficult for them in view of the traditional spaces in which they find themselves, where patriarchal structures are pervasive. Based on data obtained from a case study, this paper examines socio-cultural constraints to rural women's sexual agency in a patriarchal social order. These rules are based on a patriarchal code of respect, which is still pervasive in many aspects of the community under investigation. In terms of gender relations, the patriarchal code of respect is founded on an assumed 'naturalisation' of the two genders and the natural superiority of the male over the female. In terms of sexuality it is translated into male sex-right. The fear of HIV infection is omnipresent and results in unmarried women engaging in the negotiation of their wants and needs. Owing to the patriarchal code of respect, married women are perceived as having no choice in negotiating safer sex and are forced to put their lives at risk in contracting HIV. Unmarried women have greater although not endless choices in this regard. Although the study participants unexpectedly displayed a rather negative perception of other women, in order to strengthen women in their proximal environment the HIV epidemic may be seen as a vehicle for building solidarity among women in the community.

Glucagon-like peptide-1 receptor agonists such as exendin-4 are currently used in type 2 diabetes, and considered to have beneficial effects on the cardiovascular system. To further elucidate the effect of glucagon-like peptide-1 receptor agonists on cardiovascular diseases, we investigated the effects of exendin-4 on intimal thickening after endothelial injury. Under continuous infusion of exendin-4 at 24 nmol/kg/day, C57BL/6 mice were subjected to endothelial denudation injury of the femoral artery. Treatment of mice with exendin-4 reduced neointimal formation at 4 weeks after arterial injury without altering body weight or various metabolic parameters. In addition, in vitro studies of isolated murine, rat and human aortic vascular smooth muscle cells showed the expression of GLP-1 receptor. The addition of 10 nM exendin-4 to cultured smooth muscle cells significantly reduced their proliferation induced by platelet-derived growth factor. Our results suggested that exendin-4 reduced intimal thickening after vascular injury at least in part by the suppression of platelet-derived growth factor-induced smooth muscle cells proliferation.

    Few evaluations have assessed the factors triggering an adequate health care response to intimate partner violence. This article aimed to: 1) describe a realist evaluation carried out in Spain to ascertain why, how and under what circumstances primary health care teams respond to intimate partner violence, and 2) discuss the strengths and challenges of its application. We carried out a series of case studies in four steps. First, we developed an initial programme theory (PT1), based on interviews with managers. Second, we refined PT1 into PT2 by testing it in a primary healthcare team that was actively responding to violence. Third, we tested the refined PT2 by incorporating three other cases located in the same region. Qualitative and quantitative data were collected and thick descriptions were produced and analysed using a retroduction approach. Fourth, we analysed a total of 15 cases, and identified combinations of contextual factors and mechanisms that triggered an adequate response to violence by using qualitative comparative analysis. There were several key mechanisms -the teams' self-efficacy, perceived preparation, women-centred care-, and contextual factors -an enabling team environment and managerial style, the presence of motivated professionals, the use of the protocol and accumulated experience in primary health care- that should be considered to develop adequate primary health-care responses to violence. The full application of this realist evaluation was demanding, but also well suited to explore a complex intervention reflecting the situation in natural settings. Copyright © 2015 SESPAS.

    Posttraumatic stress disorder has been linked to women's ill health, including headaches. Intimate partner violence, which may result in posttraumatic stress disorder, is often reported by women with headaches. Prior studies of intimate partner violence and headache have estimated lifetime but not 12-month prevalence. The researchers in this study examined the relationship between headache and posttraumatic stress disorder in a novel population, and estimated 12-month and lifetime prevalence rates of intimate partner violence. Patients were recruited from a women's headache center (n = 92) during 2006-07 and completed the Migraine Disability Assessment measure of headache severity. Posttraumatic stress disorder was measured using a modified Breslau scale. Twelve-month and lifetime physical intimate partner violence were measured with the Partner Violence Screen and the STaT ("slapped, threatened and throw") measure. Multivariable regression determined factors independently associated with headache severity. Among all participants, 28.3% screened positive for posttraumatic stress disorder; 9.8% and 36.9% of women endorsed recent and lifetime intimate partner violence. Posttraumatic stress disorder was strongly associated with headache severity (β = 34.12, p = 0.01). Patients reporting lifetime intimate partner violence exhibited a trend of nine additional days of disability due to headache over 90 days. Posttraumatic stress disorder and intimate partner violence occur among a sizable proportion of women referred for headache. The authors' findings reaffirm that clinicians treating women with headaches must be aware of the possibility of posttraumatic stress disorder and intimate partner violence in such patients.
