    • To investigate the influence of baseline variables on the 4-year incidence of acute urinary retention (AUR), benign prostatic hyperplasia (BPH)-related surgery and overall clinical progression in men treated with tamsulosin, dutasteride, or a combination of both. • The 4-year Combination of Avodart® and Tamsulosin (CombAT) study was a multicenter, randomized, double-blind, parallel-group study of clinical outcomes in men aged ≥ 50 years with symptomatic (International Prostate Symptom Score [IPSS]≥ 12) BPH, with prostate-specific antigen (PSA) levels of ≥ 1.5 ng/mL and ≤ 10 ng/mL, and a prostate volume (PV) of ≥ 30 mL. • Eligible patients received tamsulosin 0.4 mg, dutasteride 0.5 mg, or a combination of both. • The primary endpoint was time to first AUR or BPH-related surgery. Secondary endpoints included clinical progression of BPH and symptoms. Posthoc analyses of the influence of baseline variables (including age, IPSS health-related quality of life [HRQL], PV, PSA, IPSS, peak urinary flow rate [Q(max) ] and body-mass index [BMI]) on the incidence of AUR or BPH-related surgery, clinical progression of BPH, and symptoms were performed. • There were 4844 men in the intent-to-treat population. Overall baseline characteristics were similar across all patient groups. • Regardless of baseline subgroup, the incidence of AUR or BPH-related surgery was higher in men treated with tamsulosin than in those treated with dutasteride or combined therapy. • Combined therapy was statistically better than tamsulosin in reducing the risk of AUR or BPH-related surgery in subgroups of baseline PV > 42.0 mL, in all subgroups of baseline PSA level, and all other baseline subgroups (P ≤ 0.001). • Across treatment groups, the incidence of clinical progression was highest in men with a baseline IPSS of BPH-related surgery and greater reductions in the RR of clinical progression and symptom deterioration on combined therapy or dutasteride monotherapy than

    To examine, using post hoc analysis, the influence of baseline variables on changes in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax ) and IPSS quality of life (QoL) in patients with moderate-to-severe lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) treated with either the α-blocker tamsulosin or the dual 5-alpha reductase inhibitor dutasteride, alone or in combination, as part of the 4-year Combination of Avodart and Tamsulosin (CombAT) study. CombAT was a 4-year, multicentre, randomized, double-blind, parallel-group study in 4844 men ≥50 years of age with a clinical diagnosis of BPH by medical history and physical examination, an IPSS ≥12 points, prostate volume (PV) ≥30 mL, total serum PSA level ≥1.5 ng/mL, and Qmax >5 mL/s and ≤15 mL/s with a minimum voided volume ≥125 mL. Eligible subjects were randomized to receive oral daily tamsulosin, 0.4 mg; dutasteride, 0.5 mg; or a combination of both. Baseline variable subgroups analysed were as follows: PV (30 to tamsulosin were performed from the general linear model with statistical significance defined as P ≤ 0.01. Combination therapy resulted in a significantly greater improvement from baseline IPSS at 48 months vs tamsulosin monotherapy across all baseline subgroups. The benefit of combination therapy over dutasteride was confined to groups with lower baseline PV (tamsulosin but not dutasteride monotherapy. Qmax improvement appeared to increase with PV and PSA level in combination therapy subjects. The proportion of subjects with an IPSS QoL ≤2 (at least mostly satisfied) at 48 months was significantly higher with combination therapy than with dutasteride for subgroups with PV 40-60 mL and PSA level tamsulosin for all PSA subgroups and PV subgroups ≥40 mL. CombAT data support the use of long-term combination therapy with dutasteride and tamsulosin in patients considered at risk for progression of BPH, as determined

    We studied the long-term results of photorefractive keratectomy (PRK) in keratoconus suspects detected by videokeratography (TMS). Bilateral inferior corneal steepening was detected in 6 candidates for PRK presenting with moderate myopia or astigmatism. Mean follow-up was 44.5 +/- 4.4 months (range, 38 to 54 mo). Mean spherical equivalent refraction was -5.18 +/- 1.60 D (mean sphere, -4.73 D; mean cyclinder, -0.92 D) which was stable for at least the preceding year. The quantitative measurement of inferior corneal steepening (I-S value) was greater than +1.60 (mean, 1.83 +/- 0.11) in all eyes. An Aesculap Meditec Mel 60 excimer laser was used for the PRK procedures and mean follow-up was 44.5 months. Postoperative pachymetric measurements were also performed in 6 eyes. Postoperative uncorrected visual acuity was 20/20 in 8 eyes (66.6%) and 20/32 or better in all eyes with a mean postoperative spherical equivalent refraction of -0.70 +/- 0.74 D (mean sphere, -0.63 D; mean cyclinder, -0.39 D). Five eyes (41.6%) were within +/- 0.50 D spherical equivalent refraction. Inferior steepening was associated with thinning of the inferior cornea which was statistically significantly thinner than the superior thickness (Student's t-test, P < .05). There were no wound healing problems or any sign that the excimer laser adversely affected the cornea during follow-up. Photorefractive keratectomy seems to be a safe procedure for reducing or eliminating myopia or astigmatism in keratoconus suspect eyes-most probably forme fruste keratoconus-with a stable refraction, but this may be different in eyes with early keratoconus, known to be a progressive disease.

    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.

    The MACHO project is a search for dark matter in the form of massive compact halo objects(MACHOs). The project has photometrically monitored tens of millions of stars in the Large Magellanic Cloud (LMC), Small Magellanic Cloud (SMC), and Galactic bulge in search of rare gravitational microlensing events caused by these otherwise invisible objects. Microlensing toward the LMC has allowed powerful statements to be made about the dark population in the halo of our Galaxy, indicating that the MACHO halo fraction could be as high as f=0.5 with a most probable MACHO mass being ~ 0.5Msun. However, to date the LMC has been the only line of sight out of our Galaxy's halo. Clearly, another line of sight would provide a consistency check on these results, as well as another contraint on models of the halo, in particular on halo flattening. The SMC affords us this second line of sight. Here we give a status report on our upcoming 4 year results toward the SMC. We present the results of a preliminary analysis on over 2.2 million stars from 3 square degrees and discuss the implications for the dark matter in the halo of our Galaxy. A detailed analysis of the microlensing candidates toward the SMC, with blending and parallax fits, will be shown. This work is dedicated to the memory of Alex Rodgers.

    Single-tooth implant restorations are commonly used to replace anterior maxillary teeth. The esthetic, functional, and biologic outcomes are, in part, a function of the abutment and crown. The purpose of this clinical study was to describe the implant, abutment, and crown survival and complication rates for CAD/CAM zirconia abutment and lithium disilicate crown restorations for single-tooth implants. As part of a broader prospective investigation that enrolled and treated 141 participants comparing tissue responses at the conical interface (CI; AstraTech OsseoSpeed), flat-to-flat interface (FI; NobelSpeedy), and platform-switch interface (PS; NanoTite Certain Prevail) of single-tooth implants, computer-aided design and computer-aided manufacturing (CAD/CAM) zirconia abutments (ATLANTIS Abutment) and cemented lithium disilicate (e.max) crowns were used in the restoration of all implants. After 2.4 years in function (3 years after implant placement), the implant, abutment, and crown of 110 participants were evaluated. Technical and biologic complications were recorded. Demographic results were tabulated as percentages with mean values and standard deviations. Abutment survival was calculated with the Kaplan-Meier method. After 2.4 years, no abutments or crowns had been lost. Abutment complications (screw loosening, screw fracture, fracture) were absent for all 3 implant groups. Crown complications were limited to 2 crowns debonding and 1 with excess cement (2.5%). Five biological complications (4.0%) were recorded. The overall complication rate was 6.5%. CAD/CAM zirconia abutments restored with cemented lithium disilicate crowns demonstrated high survival on 3 different implant-abutment interface designs. No abutment or abutment screw fracture occurred. The technical complications observed after 2.4 years were minor and reversible. The use of CAD/CAM zirconia abutments with cemented lithium disilicate crowns is associated with high technical and biologic success at 2.4

    Eliglustat is an investigational, oral substrate reduction therapy for Gaucher disease type 1 (GD1). Nineteen treatment-naïve patients have now completed 4years of an open-label study (NCT00358150). Mean hemoglobin level and platelet count increased by 2.3±1.5g/dL (baseline: 11.3±1.5g/dL) and 95% (baseline: 68,700±21,200/mm(3)), respectively. Mean spleen and liver volumes (multiples of normal, MN) decreased by 63% (baseline: 17.3±9.5 MN) and 28% (baseline: 1.7±0.4 MN), respectively. Median chitotriosidase and CCL-18 each decreased by 82%; plasma glucosylceramide and GM3 normalized. Mean bone mineral density T-score for the lumbar spine increased by 0.8 (60%) (baseline: -1.6±1.1). Femur dark marrow, a reflection of Gaucher cell infiltration into bone marrow, was reduced or stable in 17/18 patients. There were no bone crises. Most adverse events were mild and unrelated to treatment. These results extend the safety and efficacy of eliglustat reported at 1 and 2 years to 4 years. Copyright © 2014.

    Purpose: To evaluate the effects of limited field conventional cerebral radiotherapy (RT) on cognitive functions of adults. Methods and Materials: A prospective neuropsychological study was performed on 17 patients who underwent conventional limited field RT for a low-grade glioma or for a good-prognosis anaplastic glioma. Results were compared with 14 control patients with low-grade gliomas who did not receive radiotherapy. Results: A transient significant decrease of performances for the Reaction Time test was observed at 6 months in the irradiated group with return to baseline values 12 months post-RT. Subsequently, no other significant changes were observed over a 48-month follow-up period in the irradiated and nonirradiated groups. Nonetheless, when the scores of each patient were considered over time instead of the mean values of the group, one irradiated patient (5.8%) experienced progressive deterioration while two irradiated patients (11.7%) experienced long-lasting improvement. Individual changes did not occur in the control group. Conclusion: This study suggests that a transient early delayed drop of neuropsychological performances at 6 months is frequent following limited field conventional RT, but the risk of long-term cognitive dysfunction after irradiation is low, at least in the first 4 years after RT and when it is administered alone in young adults

    To evaluate the long-term effectiveness and safety of ranibizumab 0.5 mg in patients with choroidal neovascularization (CNV) secondary to pseudoxanthoma elasticum (PXE) in a real-world setting. A descriptive, observational, multicenter study in a retrospective and prospective cohort was conducted in France that included patients who had received at least one injection of ranibizumab 0.5 mg during the period October 2011 to October 2014, for CNV secondary to PXE. Eligible patients were identified by review of medical records or during routine consultations. The main objectives were to describe patient characteristics, assess changes in best-corrected visual acuity [VA, Early Treatment Diabetic Retinopathy Study (ETDRS) letters] over time, the number and reasons for ranibizumab treatment and overall safety. Of the 72 enrolled patients (98 eyes) from 23 centers, 39 (54.2%) were male and mean [±standard deviation (SD)] age was 59.6 (±8.3) years. The mean VA was 64.6 letters at the first ranibizumab injection, which was maintained at the 1-year follow-up (64.7 letters). Thereafter, the mean VA was stable until the 4-year follow-up. At 4 years, the proportion of eyes with VA gain of ≥15 letters was 3/19 (15.8%) and stable VA (change between -15 and +15 letters) was 10/19 (52.6%). Mean (±SD) annual number of ranibizumab injections was 4.1 (±4.0), lower in the second versus first year. The most common reason for ranibizumab treatment was progression of neovascular activity (42.9%). No deaths or new safety findings were reported. In patients with CNV secondary to PXE, ranibizumab 0.5 mg resulted in stable VA over 4 years with a limited number of injections. Safety findings were consistent with the established safety profile of ranibizumab.

    To compare qualitative vs quantitative results of Single Photon Emission Computerised Tomography (SPECT), calculated from percentage of 99m Tc-MDP (methylene diphosphonate) uptake, in condyles of patients with a presumptive clinical diagnosis of condylar hyperplasia. A retrospective, descriptive study was conducted on the 99m Tc-MDP SPECT bone scintigraphy reports from 51 patients, with clinical impression of facial asymmetry related to condylar hyperplasia referred by their specialist in orthodontics or maxillofacial surgery, to a nuclear medicine department in order to take this type of test. Quantitative data from 99m Tc-MDP condylar uptake of each were obtained and compared with qualitative image interpretation reported by a nuclear medicine expert. The concordances between the 51 qualitative and quantitative reports results was established. The total sample included 32 women (63%) and 19 men (37%). The patient age range was 13-45 years (21±8 years). According to qualitative reports, 19 patients were positive for right side condylar hyperplasia, 12 for left side condylar hyperplasia, with 8 bilateral, and 12 negative. The quantitative reports diagnosed 16 positives for right side condylar hyperplasia, 10 for left side condylar hyperplasia, and 25 negatives. Nuclear medicine images are an important diagnostic tool, but the qualitative interpretation of the images is not as reliable as the quantitative calculation. The agreement between the two types of report is low (39.2%, Kappa=0.13; P>.2). The main limitation of quantitative reports is that they do not register bilateral condylar hyperplasia cases.

    A large aneurysm of the left renal artery was found incidentally during abdominal ultrasound in a 39-year-old woman with no medical or family history of cardiovascular disease. Vascular pathology with a dysplastic appearance was confirmed by magnetic resonance angiography and the patient was offered transcatheter embolization. Since the position and size of the neck of the aneurysm could not be determined at angiography, detachable platinum coils were used for occlusion. The procedure was performed without complications. During a 4-year follow-up no alterations of renal function, recanalization of the aneurysm, or perfusion defects in the rest of the left renal circulation were noted.

    Due to the increase in childhood obesity, identifying children with excess body fat as early as possible is essential. Body mass index (BMI) is commonly used as a marker of body fat in children, adolescents, and adults, yet whether BMI is a valid marker of body fat in pre-school aged children remains to be confirmed. Therefore, we analyzed the associations of BMI with fat and fat-free mass in healthy 4-year-old Swedish children. The study comprised of 303 children (135 girls) participating in the MINISTOP obesity prevention trial. Fat and fat-free mass were measured using air displacement plethysmography and we computed fat mass index (FMI) and fat free mass index (FFMI) as fat and fat free mass (kg)/height 2 (m). BMI was positively yet weakly associated with percent fat mass (boys: r 2  = 0.120, P Children classified as normal weight had a wide range of percent fat mass (12.3 to 35.3%) and FMI (1.75 to 5.78 kg/m 2 ). BMI was strongly associated to both FMI and FFMI. Therefore, caution is needed when interpreting body fat status based on BMI values in pre-school children.

    Survivors of severe traumatic brain injury have a great variety of impairments and participation restrictions. Detailed descriptions of their long-term outcome are critical. We aimed to assess brain injury outcome for subjects with traumatic brain injury in terms of the International classification of functioning, disability and health. Four-year follow-up of an inception cohort of adults with severe traumatic brain injury by using face-to-face interviews with patients and proxies. Among 245 survivors at 4 years, 147 were evaluated (80% male, mean age: 32.5±14.2 years at injury); 46 (32%) presented severe disability, 58 (40%) moderate disability, and 40 (28%) good recovery. Most frequent somatic problems were fatigue, headaches, other pain, and balance. One quarter of subjects had motor impairments. Rates of cognitive complaints ranged from 25 to 68%, the most frequent being memory, irritability, slowness and concentration. With the Hospital Anxiety and Depression Scale, 43% had anxiety and 25% depression. Overall, 79% were independent in daily living activities and 40 to 50% needed help for outdoor or organizational activities on the BICRO-39. Most had regular contacts with relatives or close friends but few contacts with colleagues or new acquaintances. Subjects spent little time in productive activities such as working, studying, looking after children or voluntary work. Quality of life on the QOLIBRI scale was associated with disability level (Plife. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Alcohol-based hand sanitizers have become widely available because of widespread usage in schools, hospitals, and workplaces and by consumers. We report what we believe is the first unintentional ingestion in a small child producing significant intoxication. A 4-year-old 14-kg girl was brought to the emergency department with altered mental status after a history of ingesting an alcohol-based hand sanitizer. Physical examination revealed an obtunded child with periods of hypoventilation and a hematoma in the central portion of her forehead from a fall at home that occurred after the ingestion. Abnormal vital signs included a heart rate of 139 beats/min and temperature of 96.3 degrees F, decreasing to 93.6 degrees F. Abnormal laboratory values consisted of potassium of 2.6 mEq/L and a serum alcohol of 243 mg/dL. A computed tomography scan of her brain without contrast showed no acute intracranial abnormality. A urine drug screen for common drugs of abuse was reported as negative. The child was intubated, placed on mechanical ventilation, and admitted for medical care. She recovered over the next day without sequelae. As with other potentially toxic products, we would recommend caution and direct supervision of use when this product is available to young children.

    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.

    Full Text Available Abstract Background The existence of unilateral adrenal hyperplasia (AH has been considered a rare cause of primary hyperaldosteronism (PA. Methods In a prospective study we screened for PA in a non-selected (NSP and selected hypertensive population (SP, to define the cause of PA. We included 353 consecutive patients with hypertension; age 20 to 88 years, 165 women and 188 men, from a university-based Hypertension and Nephrology Outpatient clinics (123 SP and two primary care centres, (230 NSP from the same catch-up area. Serum aldosterone and plasma renin activity (PRA were measured and the ARR calculated. Verifying diagnostic procedure was performed in patients with both elevated aldosterone and ARR. Patients diagnosed with PA were invited for adrenal venous sampling (AVS and offered laparoscopic adrenalectomy when AVS found the disease to be unilateral. Results After screening, 46 patients, 13% of the whole population (22.8% SP and 7.8% NSP had aldosterone and ARR above the locally defined cut-off limits (0.43 nmol/l and 1.28 respectively. After diagnostic verification, 20 patients (6% had PA, (14.5% SP and 1.4% NSP. Imaging diagnostic procedures with CT-scans and scintigraphy were inconclusive. AVS, performed in 15 patients verified bilateral disease in 4 and unilateral in 10 patients. One AVS failed. After laparoscopic adrenalectomy, 4 patients were found to have adenoma and 5 unilateral AH. One patient denied operation. Conclusion The prevalence of PA was in agreement with previous studies. The study finds unilateral PA common and unilateral AH as half of those cases. As may be suspected PA is found in much higher frequency in specialised hypertensive units compared to primary care centers. AVS was mandatory in diagnosis of unilateral PA.

Between August, 2004 and March, 2010 we performed 109 total knee arthroplasties of the Columbus knee system in 101 consecutive patients suffering from primary arthrosis of the knee. Mean age was 72.4 years in women and 70.3 years in men. Mean followup was 47.3 months. The 4-year results of a group of patients who received the NexGen Full Flex implant operated by the same surgeon were used for comparison. Mean total knee score was Columbus: 175.6 and NexGen Flex: 183.4; =0.037. Mean operation time was 53 min for Columbus and 66 min for NexGen Flex; 0.05. Radiological assessment showed no signs of loosening for both groups. Therefore, the Columbus knee system can be recommended for flexion angles up to 140∘.

    The promotion of socio-emotional skills in educational contexts is highly beneficial to individuals' global adjustment and development. Evaluation research suggests that interventions for the promotion of socio-emotional skills are effective. However, most of this work has been carried out in the USA and there is now a pressing need to evaluate interventions at the cross-cultural level. This 4-year study evaluated the effectiveness of a teacher manual-based intervention for the promotion of social and emotional skills in Portuguese elementary school children. Using a quasi-experimental design, teachers taught manual-based strategies to children in the experimental group, focusing on specific social and emotional skills. These strategies were integrated as part of the curricular activities. Results showed statistically significant differences between the experimental group and the control group on the evaluated outcomes (self-control, emotional differentiation, emotional regulation, social skills, and self-esteem). For each of the dimensions studied, effect sizes were large (above 0.80). Findings are similar to those reported by international research evaluating the effectiveness of programmes for the promotion of social and emotional skills in school-age children. This study is an important contribution in the establishment of evidence-based socio-emotional skills programmes at the cross-cultural level.

    Purpose: To examine the incidence and clinical relevance of fat necrosis after accelerated partial-breast irradiation (PBI) using interstitial high-dose-rate brachytherapy (HDR-BT) in comparison with partial-breast electron irradiation (ELE) and whole-breast irradiation (WBI). Methods and Materials: Between 1998 and 2004, 258 early-stage breast cancer patients were randomized to receive 50 Gy WBI (n = 130) or PBI (n = 128). The latter consisted of either 7 x 5.2 Gy HDR-BT (n = 88) or 50 Gy ELE (n = 40). The incidence of fat necrosis, its impact on cosmetic outcome, accompanying radiologic features, and clinical symptoms were evaluated. Results: The 4-year actuarial rate of fat necrosis was 31.1% for all patients, and 31.9%, 36.5%, and 17.7% after WBI, HDR-BT and ELE, respectively (p WBI/HDR-BT = 0.26; p WBI/ELE = 0.11; p ELE/HDR-BT = 0.025). The respective rate of asymptomatic fat necrosis was 20.2%, 25.3%, and 10% of patients. The incidence of symptomatic fat necrosis was not significantly different after WBI (8.5%), HDR-BT (11.4%), and ELE (7.5%). Symptomatic fat necrosis was significantly associated with a worse cosmetic outcome, whereas asymptomatic fat necrosis was not. Fat necrosis was detectable with mammography and/or ultrasound in each case. Additional imaging examinations were required in 21% of cases and aspiration cytology in 42%. Conclusions: Asymptomatic fat necrosis is a common adverse event of breast-conserving therapy, having no significant clinical relevance in the majority of the cases. The incidence of both symptomatic and asymptomatic fat necrosis is similar after conventional WBI and accelerated partial-breast HDR-BT

    Cervical spondylotic myelopathy is caused by cervical stenosis. Several techniques have been described for the treatment of multilevel disease, such as the anterior corpectomy with titanium mesh cage and anterior cervical plate placement, which has the advantage of performing a wider decompression and using the same bone as graft. However, it has caused controversy since the collapse of the mesh cage continues being a major limitation of this procedure. A prospective 4-year follow-up study was conducted in 7 patients diagnosed with cervical stenosis, who were treated surgically by one level corpectomy with titanium mesh cage and anterior cervical plate placement, evaluating them by radiographs and clinical scales. 7 patients, 5 women and 2 males were studied. The most common level was C5 corpectomy (n=4). The Neck Disability Index (NDI) preoperative average was 30.01±24.32 and 4-year postoperative 16.90±32.05, with p=0.801. The preoperative and 4-year postoperative Nürick was 3.28± 48 and 3.14±1.21 respectively, with p=0.766. Preoperative lordosis was 14.42±8.03 and 4-year postoperative 17±11.67 degrees, with p=0.660. The immediate postoperative and 4-year postoperative subsidence was 2.69±2.8 and 6.11±1.61 millimeters respectively, with p=0.0001. Despite the small sample, the subsidence of the mesh cage is common in this procedure. No statistically significant changes were observed in the lordosis or Nürick scale and NDI.

    This report summarises results and experiences gathered from field trials with recycling of pre-treated wastewater, diverted human urine mixed with water, and municipal sludge, within plantations of willow species specifically selected for biomass production. Experimental sites were established in Sweden (Roma), France (Orchies), Northern Ireland (Culmore) and Greece (Larissa). The project was carried out during a 4-year period with financial support from the EU FAIR Programme. The experimental sites were supplied with primary effluent from municipal treatment plants (Culmore and Larissa), stored industrial effluent from a chicory processing plant (Orchies), biologically treated and stored municipal wastewater (Roma) and human urine mixture from diverting low-flush toilets mixed with water (Roma). Application rates of the wastewaters or the urine mixture were equivalent to the calculated evapotranspiration rate at each site. Wastewaters were also applied up to three times this value to evaluate any possible negative effects. Estimations and evaluations were carried out mainly concerning: biomass growth, potential biological attacks of the plantations, plant water requirements, fertilisation effects of the wastewater, plant uptake of nutrients and heavy metals from applied wastewater, possible soil or groundwater impact, sanitary aspects, and potentials for removal in the soil-plant filter of nutrients and biodegradable organic material from applied wastewater. The results clearly indicated that biomass production in young willow plantations could be enhanced substantially after recycling of wastewater resources. The impact on soil and groundwater of nutrients (nitrogen and phosphorus) and heavy metals (copper, zinc, lead and cadmium) was limited, even when the application of water and nutrients exceeded the plant requirements. Also, the soil-plant system seemed to function as a natural treatment filter for pre-treated (primary settled) wastewater, with a treatment

    National blood use patterns in sub-Saharan Africa are poorly described. Although malaria and maternal hemorrhage remain important drivers of blood demand across Africa, economic growth and changes in malaria, HIV/AIDS, and noncommunicable disease epidemiology may contribute to changes in blood demand. We evaluated indications for blood use in Namibia, a country in southern Africa, using a nationally representative sample and discuss implications for the region. Clinical and demographic data related to the issuance of blood component units in Namibia were reviewed for a 4-year period (August 1, 2007-July 31, 2011). Variables included blood component type, recipient age and sex, and diagnosis. Diagnoses reported by clinicians were reclassified into International Statistical Classification of Diseases, 10th Revision categories. Multiple imputation methods were used to complete a data set missing age, sex or diagnosis data. Descriptive analyses were conducted to describe indications for transfusions and use of red blood cells (RBCs), platelets, and plasma. A total of 39,313 records accounting for 91,207 blood component units were analyzed. The median age of Namibian transfusion recipients was 45 years (SD, ±19). A total of 78,660 RBC units were issued in Namibia during the study period. Red blood cells transfused for "unspecified anemia" accounted for the single largest category of blood issued (24,798 units). Of the overall total, 38.9% were for diseases of the blood and blood-forming organs (D50-D89). Infectious disease (A00-B99), pregnancy (O00-O99), and gastrointestinal (K20-K93) accounted for 14.8%, 11.1%, and 6.1% of RBC units issued, respectively. Although a specific diagnosis of malaria accounted for only 2.7% of pediatric transfusions, an unknown number of additional transfusions for malaria may have been categorized by requesting physicians as unspecified anemia and counted under diseases of blood forming organs. During the study period, 9751 units of fresh

  9. Expression of activated PIK3CA in ovarian surface epithelium results in hyperplasia but not tumor formation.

    Directory of Open Access Journals (Sweden)

    Shun Liang

    Full Text Available The Phosphatidylinositol 3'-kinase is a key regulator in various cancer-associated signal transduction pathways. Genetic alterations of its catalytic subunit alpha, PIK3CA, have been identified in ovarian cancer. Our in vivo data suggests that PIK3CA activation is one of the early genetic events in ovarian cancer. However, its role in malignant transformation of ovarian surface epithelium (OSE is largely unclear.Using the Müllerian inhibiting substance type II receptor (MISIIR promoter, we generated transgenic mice that expressed activated PIK3CA in the Müllerian epithelium. Overexpression of PIK3CA in OSE induced remarkable hyperplasia, but was not able to malignantly transform OSE in vivo. The consistent result was also observed in primary cultured OSEs. Although enforced expression of PIK3CA could not induce OSE anchorage-independent growth, it significantly increased anchorage-independent growth of OSE transformed by mutant K-ras.While PIK3CA activation may not be able to initiate OSE transformation, we conclude that activation of PIK3CA may be an important molecular event contributing to the maintenance of OSE transformation initiated by oncogenes such as K-ras.

    Our objective was to identify the most accurate method of endometrial sampling for the diagnosis of complex atypical hyperplasia (CAH), and the related risk of underestimation of endometrial cancer. We conducted a systematic literature search in PubMed and EMBASE (January 1999-September 2013) to identify all registered articles on this subject. Studies were selected with a 2-step method. First, titles and abstracts were analyzed by 2 reviewers, and 69 relevant articles were selected for full reading. Then, the full articles were evaluated to determine whether full inclusion criteria were met. We selected 27 studies, taking into consideration the comparison between histology of endometrial hyperplasia obtained by diagnostic tests of interest (uterine curettage, hysteroscopically guided biopsy, or hysteroscopic endometrial resection) and subsequent results of hysterectomy. Analysis of the studies reviewed focused on 1106 patients with a preoperative diagnosis of atypical endometrial hyperplasia. The mean risk of finding endometrial cancer at hysterectomy after atypical endometrial hyperplasia diagnosed by uterine curettage was 32.7% (95% confidence interval [CI], 26.2-39.9), with a risk of 45.3% (95% CI, 32.8-58.5) after hysteroscopically guided biopsy and 5.8% (95% CI, 0.8-31.7) after hysteroscopic resection. In total, the risk of underestimation of endometrial cancer reaches a very high rate in patients with CAH using the classic method of evaluation (i.e., uterine curettage or hysteroscopically guided biopsy). This rate of underdiagnosed endometrial cancer leads to the risk of inappropriate surgical procedures (31.7% of tubal conservation in the data available and no abdominal exploration in 24.6% of the cases). Hysteroscopic resection seems to reduce the risk of underdiagnosed endometrial cancer. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

    Soil sealing is one of the most pervasive forms of soil degradation that follows urbanization and, despite innovative pavements (i.e. pervious) are being installed in urban areas to mitigate it, there is little research on the effects of pervious pavements on soil water and carbon cycle and on the physiology of urban trees. The aim of this 4-year experiment was to assess the effects of three pavements, differing in permeability to water and gases, on some soil physical parameters, and on growth and physiology of newly planted Celtis australis and Fraxinus ornus. Treatments were: 1) impermeable pavement (asphalt on concrete sub-base); 2) permeable pavement (pavers on crushed rock sub-base); 3) porous design (porous pavement on crushed rock sub-base); 4) control (unpaved soil, kept free of weed by chemical control). Soil (temperature, moisture, oxygen content and CO 2 efflux) and plant (above- and below-ground growth, leaf gas exchange, chlorophyll fluorescence, water relations) parameters were measured. All types of pavements altered the water cycle compared to unpaved soil plots, but this disturbance was less intense in porous pavements than in other soil cover types. Porous pavements allowed both higher infiltration and evaporation of water than both pavers and asphalt. Reduction of evaporative cooling from soil paved with permeable and impermeable pavements contributed to significant soil warming: at 20cm depth, soils under concrete pavers and asphalt were 4 and 5°C warmer than soil covered by porous pavements and unpaved soils, respectively. Thus, enhancing evaporation from paved soil by the use of porous pavements may contribute to mitigating urban heat islands. CO 2 greatly accumulated under impermeable and permeable pavements, but not under porous pavements, which showed CO 2 efflux rates similar to control. Soil oxygen slightly decreased only beneath asphalt. Growth of newly planted C. australis and F. ornus was little affected by pavement type. Tree

    Long thoracic nerve (LTN) injury can result in ipsilateral serratus anterior palsy and scapular winging. Traditional means of evaluating patients with suspected LTN injury include physical examination and electrodiagnostic studies. The purpose of our study is to describe high-resolution magnetic resonance (MR) findings in patients with clinical suspicion of LTN neuropathy. In this HIPAA-compliant, IRB-approved, retrospective study, two radiologists reviewed MR imaging performed for long thoracic neuropathy. Clinical presentation, electrodiagnostic studies and MR imaging of 20 subjects [mean age 37 ± 13 years; 25% (5/20) female] were reviewed. Observers reviewed MR imaging for LTN signal intensity, size, course, presence or absence of mass and secondary findings [skeletal muscle denervation (serratus anterior, trapezius, rhomboid) and scapular winging]. Descriptive statistics were reported. Clinical indications included trauma (n = 5), hereditary neuropathy (n = 1), pain (n = 8), winged scapula (n = 6), brachial plexitis (n = 4) and mass (n = 1). Electrodiagnostic testing (n = 7) was positive for serratus anterior denervation in three subjects. Abnormal LTN signal intensity, size, course or mass was present in 0/20. Secondary findings included skeletal muscle denervation in the serratus anterior in 40% (8/20), trapezius in 20% (4/20) and rhomboid in 20% (4/20). In 5% (1/20), an osteochondroma simulated a winged scapula, and in 2/20 (10%) MR showed scapular winging. High-resolution MR imaging is limited in its ability to visualize the long thoracic nerve directly, but does reveal secondary signs that can confirm a clinical suspicion of LTN injury. (orig.)

    Concomitant chemo-radiotherapy is the standard treatment for advanced nasopharyngeal carcinoma (NPC). Induction chemotherapy may improve the results further by enhancing both loco-regional and distant control. Fifty patients with untreated, stage IV (UICC 1992) undifferentiated NPC were initially treated with three courses of epidoxorubicin, 90 mg/m(2), day 1 and cisplatin, 40 mg/m(2), days 1 and 2, every three weeks and then underwent three courses of cisplatin, 20 mg/m(2)/day, days 1-4 and fluorouracil, 200mg/m(2)/day, days 1-4 (weeks 1, 4, 7), alternated to three splits of radiation (week 2-3, 5-6, 8-9-10) up to 70 Gy. All patients but one received 3 cycles of induction chemotherapy. Toxicities from induction chemotherapy were grade III or IV mucositis (2%), grade III or IV nausea/vomiting (22%), grade III or IV hematological toxicity (6%). At the end of induction phase 12% of CRs, 84% of PRs were recorded. Toxicities from alternating chemo-radiotherapy were grade III or IV mucositis (30%), grade III or IV nausea/vomiting (8%), grade III or IV hematological toxicity (24%). Overall, 86% of CRs and 14% of PRs were observed. Four-year progression free survival and overall survival rates are 71% and 81%, respectively. In a small number of patients studied, no correlation between the level of EGFR overexpression and outcomes was detected. In locally advanced UNPC our combined program including induction chemotherapy followed by alternating chemo-radiotherapy is active and gives promising long-term outcomes with acceptable toxicity and optimal patients' compliance. This program merits to be tested in a phase III trial.

    Full Text Available Graves′ disease is an autoimmune thyroid condition characterized by the production of autoantibodies against the thyrotropin receptor. It is known to be associated with autoimmune conditions such as myasthenia gravis, Addison′s disease, type 1 diabetes mellitus, and vitiligo. We present a case of rare autoimmune association of Graves′ disease with thymic hyperplasia which regressed after treatment with antithyroid drugs. Exact pathophysiology of thymic hyperplasia in Graves′ is not well understood; it is likely to be the result of rather than the cause of Graves′ disease.

    To assess the value of cardiac structure/function in predicting heart rate variability (HRV) and the possibly predictive value of HRV on cardiac parameters. Baseline and 4-year follow-up data from the population-based CARLA cohort were used (790 men, 646 women, aged 45-83 years at baseline and 50-87 years at follow-up). Echocardiographic and HRV recordings were performed at baseline and at follow-up. Linear regression models with a quadratic term were used. Crude and covariate adjusted estimates were calculated. Missing values were imputed by means of multiple imputation. Heart rate variability measures taken into account consisted of linear time and frequency domain [standard deviation of normal-to-normal intervals (SDNN), high-frequency power (HF), low-frequency power (LF), LF/HF ratio] and non-linear measures [detrended fluctuation analysis (DFA1), SD1, SD2, SD1/SD2 ratio]. Echocardiographic parameters considered were ventricular mass index, diastolic interventricular septum thickness, left ventricular diastolic dimension, left atrial dimension systolic (LADS), and ejection fraction (Teichholz). A negative quadratic relation between baseline LADS and change in SDNN and HF was observed. The maximum HF and SDNN change (an increase of roughly 0.02%) was predicted at LADS of 3.72 and 3.57 cm, respectively, while the majority of subjects experienced a decrease in HRV. There was no association between further echocardiographic parameters and change in HRV, and there was no evidence of a predictive value of HRV in the prediction of changes in cardiac structure. In the general population, LADS predicts 4-year alteration in SDNN and HF non-linearly. Because of the novelty of the result, analyses should be replicated in other populations.

    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.

    The aim of the investigation was to assess the prevalence of ovarian adrenal rest tumours and polycystic ovaries in female patients with congenital adrenal hyperplasia (CAH). Thirteen female CAH patients (median age 19.8 years, range 14.8-23.5 years) underwent transvaginal (n=6) or transabdominal (n=7) ultrasonography by a gynaecologist and MR imaging (n=13) of the ovaries (pre and post contrast-enhanced T1- and T2-weighted images). Ovarian adrenal rest tumours were defined as small hypoechoic and multifocal nodules on ultrasound and isointense lesions on T1- and hypointense on T2-weighted MR images (derived from characteristics of testicular adrenal rest tumours). Polycystic ovaries were defined as the presence of {>=}10 follicles arranged peripherally around or scattered throughout increased stroma. No ovarian adrenal rest tumours were found either on ultrasound, or by MR imaging. Polycystic ovaries were found in 2 of the 13 patients (15.4%), both with ultrasound and MR. No ovarian adrenal rest tumours were detected in these female CAH patients, which suggests that ovarian adrenal rest tumours in CAH females are rare. The prevalence of polycystic ovaries corresponded to that in the general population. From these results, we would suggest that routine ovarian imaging in CAH females is not indicated. However, when ovarian dysfunction is present, ovarian imaging is advised, first by ultrasonography, to detect ovarian adrenal rest tumours or polycystic ovaries. (orig.)

    of p53 and Ki-67 expression in 8 cases demonstrated overexpression of p53 (n = 2; 1 with overlying dysplasia and 1 with overlying CIS), and Ki-67 (n = 5; 2 with overlying dysplasia and 3 with overlying CIS). Taken together, these results suggest that atypical papillary hyperplasia is most frequently associated with CIS and high-grade papillary cancer. In some cases, CIS or dysplasia may evolve into atypical papillary hyperplasia, with further progression to high-grade papillary cancer. This process may be analogous to papillary hyperplasia without cytologic atypia progressing to low-grade papillary urothelial neoplasms. Copyright 2002, Elsevier Science (USA). All rights reserved.

    PIK3CA, the gene coding for the p110α subunit of phosphoinositide 3-kinase, is frequently mutated in a variety of human tumors including breast cancers. To better understand the role of mutant PIK3CA in the initiation and/or progression of breast cancer, we have generated mice with a conditional knock-in of the common activating mutation, Pik3caH1047R, into one allele of the endogenous gene in the mammary gland. These mice developed a ductal anaplasia and hyperplasia by 6 weeks of age characterized by multi-layering of the epithelial lining of the mammary ducts and expansion of the luminal progenitor (Lin−; CD29lo; CD24+; CD61+) cell population. The Pik3caH1047R expressing mice eventually develop mammary tumors with 100% penetrance but with a long latency (>12 months). This is significantly longer than has been reported for transgenic models where expression of the mutant Pik3ca is driven by an exogenous promoter. Histological analysis of the tumors formed revealed predominantly ERα-positive fibroadenomas, carcinosarcomas and sarcomas. In vitro induction of Pik3caH1047R in immortalized mammary epithelial cells also resulted in tumor formation when injected into the mammary fat pad of immunodeficient recipient mice. This novel model, which reproduces the scenario of a heterozygous somatic mutation occurring in the endogenous PIK3CA gene, will thus be a valuable tool for investigating the role of Pik3caH1047R mutation in mammary tumorigenesis both in vivo and in vitro.

    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.

    As the clinical effects of the available α1-adrenoceptors (ARs) blockers are usually considered comparable for treatment in patients suffering from lower urinary tract symptoms (LUTS) secondary to prostatic enlargement, officially recognised guidelines do not make specific recommendations regarding the choice of which agent should be considered according to the patient's characteristics. To analyse data supporting the use of silodosin, a highly selective once-daily dosing α1-ARs blocker, in different daily clinical practice scenarios. A structured literature review was performed using data retrieved from articles assessing the role of silodosin in the management of LUTS secondary to benign prostatic hyperplasia (BPH). A literature search of English language publications was performed using MEDLINE(®) and Web of Science from 2000 to 2012 using the terms LUTS; BPH; silodosin; α1-ARs blockers. The papers with the highest level of evidence were identified and represent the basis of the present review. Available data coming from basic research analyses, randomised trials and prospective studies showed that silodosin is efficacious for the initial management of patients with LUTS. Clinical developmental safety data from patients receiving silodosin with concomitant antihypertensive therapy do not indicate an increase in risk of orthostatic hypotension. In this context, a recent study demonstrated that silodosin can be safely administered to patients who are consensually assuming phosphodiesterase type 5 inhibitors. A recent randomised crossover study comparing the efficacy of silodosin and tamsulosin in patients with LUTS showed that further significant improvement was observed after switching to silodosin treatment, while worsening or little improvement was observed after switching to tamsulosin treatment. Preliminary results seem to demonstrate a potential role of silodosin in the treatment of chronic prostatitis/chronic pelvic pain syndrome and to facilitate

    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.

    It is unknown whether the quantity or quality of green space is more important for mental wellbeing. We aimed to explore associations between availability of, satisfaction with, and use of green space and mental wellbeing among children aged 4 years in a multi-ethnic sample. We did a 4-year follow-up assessment of participants in the Born in Bradford longitudinal cohort study, which recruited children and mothers at the city's main maternity unit from 2007 to 2011. The primary outcome was parent-reported mental wellbeing for children aged 4 years, assessed with the standardised Strengths and Difficulties Questionnaire. Total, internalising, and externalising behavioural difficulties and prosocial behaviour scales were computed (with higher scores indicating greater difficulties or more prosocial behaviour). Residential green space around participants' home addresses and distance to major green spaces were computed with the normalised difference vegetation index (NDVI). A subsample of participants completed additional questionnaires on measures of satisfaction with, and use of, local green spaces. Multiple regressions examined associations between green space and children's mental wellbeing and explored moderation by ethnicity (white British vs south Asian) and socioeconomic status. Between Oct 1, 2012, and June 30, 2015, 2594 mothers attended a follow-up appointment during which they completed a detailed questionnaire assessing the health of their child. 1519 (58%) participants were of south Asian origin, 740 (29%) of white British origin, and 333 (13%) of another ethnicity. Data on ethnicity were missing for two participants. 832 (32%) of 2594 participants completed additional questionnaires. Ethnicity moderated associations between residential green space and mental wellbeing (pspace was associated with fewer internalising behavioural difficulties (mean NDVI 100 m: β -2·35 [95% CI -4·20 to -0·50]; 300 m: -3·15 [-5·18 to -1·13]; 500 m: -2·85 [-4·91 to -0

    The real thymic hyperplasia is benign disease sometimes simulating malignant tumours. The aim of this study is to analyse the clinical symptoms of real thymic hyperplasia and the results from imaging diagnostic based on our clinical material. Clinical material include 27 children, aged from two months to 15 years, admitted in department of thoracic surgery, for a period of 20 years (1985 - 2004). We retrospectively analyze the clinical signs and results from X-ray investigation, CT (Siemens Somatom DRG and Philips Secura) and echocardiography (Acuson TX, 5 and 7 MHz). We discuss the diagnostic value of different methods as well as typical and atypical findings. (authors)

    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.

    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.

    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.

    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

    Compare safety and tolerability of the Prolieve(®) System with the Targis(®) System using objective and subjective measures. Thirty-four men with symptomatic benign prostatic hyperplasia (BPH) were randomized to a single treatment with either the Prolieve or Targis system; 30 were treated and then followed for 6 months. After post-treatment bladder fill with ≥200 mL saline, patients were catheterized if they could not void after 2 hours or had a postvoid residual >150 mL. Catheter use, visual analog scale (VAS) tolerability scores, American Urological Association scores, and safety were assessed. After treatment, 15/16 (94%) Prolieve patients remained catheter-free compared with 3/14 (21%) Targis patients (P = 0.0001). Foley catheter indwelling time was 58.8 hours for the one Prolieve patient compared with 103.9 hrs (range 54-270 h) for the Targis patients (n = 9). Targis patients' catheterization requirements were: Seven Foley only, two intermittent self-catheters only, and two needing both. Intermittent self-catheterization continued for 1 month in two Targis patients. VAS tolerability scores were 24% to 50% lower during Prolieve treatment vs Targis (P 0.05). Overall, the incidence of device-related adverse events was 31% (Prolieve) compared with 64% (Targis) (P > 0.05)-most prevalently, urinary retention, dysuria, and hematuria. No device-related serious adverse events occurred. Prolieve provided enhanced near-term therapeutic benefit over Targis as assessed by catheterization, tolerability, and symptom relief, which may assist physician and patient decision-making when selecting an office-based transurethral microwave therapy option for patients.

    Flat epithelial atypia (FEA) of the breast have a tendency to calcify and, as such, are becoming increasingly detected by mammography. There is no consensus yet on whether to excise these lesions or not after diagnosis on core needle biopsies (CNB). We reviewed 3,948 cases of breast CNB between June 2004 and June 2009 correlating histomorphologic, radiological, and clinical features. There were 3.7 % (145/3,948) pure FEA and 1.5 % (58/3,948) concomitant FEA and atypical ductal hyperplasia (ADH). In the pure FEA population, 46.2 % (67/145) had microcalcifications on mammography with 65.5 % (95/145) of patients undergoing subsequent excisional biopsies with the following findings: benign 20 % (19/95), ADH 37.9 % (36/95), ductal carcinoma in situ (DCIS) 1.1 % (1/95), and DCIS and invasive ductal carcinoma (IDC) 2.1 % (2/95). In the concomitant FEA and ADH group, 86.2 % (50/58) patients had microcalcifications on radiograph with 74.1 % (43/58) of patients undergoing subsequent excisions with: benign 23.3 % (10/43), DCIS 9.3 % (4/43), DCIS and IDC 4.7 % (2/43), DCIS + lobular carcinoma in situ + invasive lobular carcinoma 2.3 % (1/43), and tubular carcinoma 2.3 % (1/43). The incidence of carcinoma in the FEA + ADH group is 18.6 % (8/43) and 3.2 % (3/95) for the pure FEA group. This difference is statistically significant (p = 0.0016). The relative risk of carcinoma in the ADH + FEA group versus the pure FEA group is 6.4773, with 95 % CI of 1.8432 and 22.76 24. Five-year mean follow-up in the unexcised pure FEA did not show any malignancies. These findings suggest that pure FEA has a very low association with carcinoma, and these patients may benefit from close clinical and mammographic follow-up while the combined pure FEA and ADH cases may be re-excised.

    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.

    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)

    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.

    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

    2011-01-01

    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.

    2010-01-01

    Florid lymphoid hyperplasia in the terminal ileum can present to surgeons as an acute abdominal pain. Only few cases were reported in the literature. Our case illustrates that a rare case of florid lymphoid hyperplasia can present to surgeons as acute appendicitis. During the operation the gross appearance may mimic Crohn’s disease. A limited resection is sufficient to clinch the diagnosis of florid lymphoid hyperplasia / Crohn’s disease. In florid lymphoid hyperplasia limited resection may b...

  6. Analysis of arterial intimal hyperplasia: review and hypothesis

    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

    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.

    Transrectal sonography of prostate was sensitive to textural changes produced by both benign prostate hyperplasia (BPH) and prostate cancers. During recent 4 years, twenty cases of BPH and twenty cases of prostate cancers proven histologically were analyzed in their sonographic features, retrospectively, by using transrectal prostate sonography and suprapubic prostate sonography. The results were as follows: 1. Mean weights of BPH and prostate cancers was 40.4g and 47.6g, respectively. 2. Sonographic features of BPH revealed isoechogenecity in 11 cases, homogeneity in 18 cases, well defined capsular margins in 19 cases, and calcification in 16 cases. 3. Sonographic features of prostate cancers revealed mixed echogenecity in 14 cases, inhomogeneity in 15 cases, poorly defined capsular margin in 14 cases, and calcifications in 13 cases. 4. Authors concluded that prostate sonography were valuable diagnostic modality in the differentiation of BPH and prostate cancers.

    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...

    PurposeTo compare clinical and urodynamic results of transurethral resection of the prostate (TURP) to original and PErFecTED prostate artery embolization (PAE) methods for benign prostatic hyperplasia.MethodsWe prospectively randomized 30 patients to receive TURP or original PAE (oPAE) and compared them to a cohort of patients treated by PErFecTED PAE, with a minimum of 1-year follow-up. Patients were assessed for urodynamic parameters, prostate volume, international prostate symptom score (IPSS), and quality of life (QoL).ResultsAll groups were comparable for all pre-treatment parameters except bladder contractility and peak urine flow rate (Q{sub max}), both of which were significantly better in the TURP group, and IIEF score, which was significantly higher among PErFecTED PAE patients than TURP patients. All groups experienced significant improvement in IPSS, QoL, prostate volume, and Q{sub max}. TURP and PErFecTED PAE both resulted in significantly lower IPSS than oPAE but were not significantly different from one another. TURP resulted in significantly higher Q{sub max} and significantly smaller prostate volume than either original or PErFecTED PAE but required spinal anesthesia and hospitalization. Two patients in the oPAE group with hypocontractile bladders experienced recurrence of symptoms and were treated with TURP. In the TURP group, urinary incontinence occurred in 4/15 patients (26.7 %), rupture of the prostatic capsule in 1/15 (6.7 %), retrograde ejaculation in all patients (100 %), and one patient was readmitted for temporary bladder irrigation due to hematuria.ConclusionsTURP and PAE are both safe and effective treatments. TURP and PErFecTED PAE yield similar symptom improvement, but TURP is associated with both better urodynamic results and more adverse events.

    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)

    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.

Materials and Methods: This was a single-country, prospective, observational cohort study in which patients newly prescribed tadalafil 5 mg QD for the treatment of BPH/LUTS were followed-up for 12±2 or 24±2 weeks, or to the last treatment, during post-marketing surveillance. Safety was evaluated in terms of the frequency of treatment-emergent adverse events (TEAEs and serious adverse events (SAEs. Effectiveness was assessed by changes in the International Prostate Symptom Score (IPSS from baseline to each endpoint. Results: All patients receiving ≥1 dose of tadalafil 5 mg QD (N=637 were included in the safety population. Two percent of patients (n=13 experienced 15 TEAEs of mild (n=10; 66.7% or moderate (n=5; 33.3% severity. No severe TEAEs and no SAEs were reported. Effectiveness evaluations included all patients receiving tadalafil who had both baseline and endpoint observations (12-week, N=265; 24-week, N=44. Compared with baseline, the mean IPSS total score (±standard error significantly improved by 4.7±0.3 and 6.4±0.7 points at the 12- and 24-week endpoints, respectively (p<0.0001, with significant improvements also observed on the storage, voiding, and quality of life subscores. In total, 69.1% of the patients had a clinically meaningful ≥3-point improvement in the IPSS total score. Conclusions: Tadalafil 5 mg QD was well tolerated and effective in Korean men with BPH/LUTS in a real-world clinical setting.

    Does access to 4-year colleges affect degree completion for students who would otherwise attend 2-year colleges? Admission to Georgia’s 4-year public sector requires minimum SAT scores. Regression discontinuity estimates show that access to this sector increases 4-year college enrollment and college quality, largely by diverting students from 2-year colleges. Access substantially increases bachelor’s degree completion rates for these relatively low-skilled students. SAT retaking behavior sugg...

    A case of hemifacial hyperplasia that presented with muscular, skeletal, and dental hyperplasia along with lipomatous infiltration was described. Advanced imaging was useful in identifying the lipomatous infiltration present in the lesion, which raises the possibility of lipomatosis having a diverse presentation in hemifacial hyperplasia. As there was a scarcity of related literature in the field of dentomaxillofacial radiology, this report would make us familiar with its computed tomographic and magnetic resonance image findings.

    1983-01-01

    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

    Abstract Background Working Health Service Scotland (WHSS) supports the self-employed and employees of small and medium-sized enterprises (SMEs) in Scotland with a health condition affecting their ability to work, who are either absent or at risk of becoming absent due to it. Aims To evaluate the impact on health and work outcomes of WHSS clients over a 4-year period. Methods Data were collected at enrolment, entry, discharge and follow-up at 3 and 6 months after discharge. Clients completed up to three validated health questionnaires at entry and discharge—EuroQol five dimensions (EQ-5D) and visual analogue scale (VAS); Hospital Anxiety and Depression Scale (HADS); and Canadian Occupational Performance Measure (COPM). Results A total of 13463 referrals occurred in the 4-year period; 11748 (87%) were eligible and completed entry assessment and 60% of the latter completed discharge paperwork. The majority of referrals were due to musculoskeletal conditions (84%) while 12% were referred with mental health conditions. Almost a fifth (18%) of cases were absent at entry and back at work at discharge. Work days lost while in WHSS was associated with age, length of absence prior to entering WHSS, primary health condition and time in programme. All health measures showed significant improvements from entry to discharge. Improvement in general health was sustained at 3- and 6-month follow-up. Conclusions The WHSS evaluation findings indicate that participation was associated with positive changes to health and return-to-work. The extent of the positive change in health measures and work ability can be highly important economically for employees and employers. PMID:29390161

    At birth the child's kidney is anatomically and functionally immature and the Hg uptake rate is only a quarter that of an adult. At 12 months this value is already 3/4 that of the adult and the final normal mature values are reached between 3 and 4 years. A curve of normal values for children below 4 years old is proposed, though being based on a small number of measurements only it must be taken as provisional [fr

  11. Role of Hyperplasia of Gingival Lymphatics in Periodontal Inflammation.

    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.

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 Aim: Benign prostatic hyperplasia (BPH also known as nodular hyperplasia, benign enlargement of the prostate refers to the increase in size of the prostate in middle aged and elderly men. Although four different types of specific alpha blocker have been used in the treatment of BPH it remains controversial that which alpha adrenergic blocker is effective than others. The aim of this study is to compare the efficacy of 4 different alpha blockers agents on the treatment of BPH. Material and Methods: Between June 2005 and December 2008 a total of 135 consecutive patients with diagnosed of BPH were evaluated in our clinic. Patients were randomized into four groups according to alpha blocker types as fallows: group I, doxazosin 4 mg; group II, tamsulosin 0.4 mg; group III, terazosin 5 mg; and group IV, alfuzosin 10 mg. All patients were followed up with International Prostatic Symptom Score (IPSS, maximal urinary flow rates (Qmax and adverse effects were determined at baseline and again at least 3 months as efficacy parameters. Results: The mean age of the patients were 59.8±5.4 years, 58.9±6.4 years, 58.7±5.1 years, and 59.2±5.5 years in group I, group II, group III, and group IV, respectively (p>0.05. After 3 months treatment with alpha blockers the improvements in IPSS were found as 2.73, 3.73, 3.55 and 4.44 in group I, group II, group III, and group IV, respectively. Maximum urine flow rates increased as 2.81 ml/sec, 3.24 ml/sec, 3.88 ml/sec and 4.49 ml/sec in group I, group II, group III, and group IV, respectively. However, among 4 alpha blockers statistically significant difference was found only between doxazosin and alfuzosin groups according to uroflowmetry and IPSS results. According to these results, when compared adverse effect, the significant difference was observed only in tamsulosine group. Conclusions: As a result we can say that except retrograde ejaculation in tamsulosine group, adverse effects are not different between the

    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.

    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

    Ischemic pseudo-cellular crescent (IPCC) that is induced by ischemia and composed of hyperplastic glomerular parietal epithelial cells resembles cellular crescent. In this study, we aimed to assess the clinical and pathological features of IPCC in renal biopsy to avoid over-diagnosis and to determine the diagnostic basis. 4 IPCC cases diagnosed over a 4-year period (2012-2015) were evaluated for the study. Meanwhile, 5 cases of ANCA-associated glomerulonephritis and 5 cases of lupus nephritis (LN) were selected as control. Appropriate clinical data, morphology, and immunohistochemical features of all cases were retrieved. Results showed that the basement membrane of glomerulus with IPCC appeared as a concentric twisted ball, and glomerular cells of the lesion were reduced even entirely absent, and the adjacent afferent arterioles showed sclerosis or luminal stenosis. Furthermore, immune globulin deposition, vasculitis, and fibrinous exudate have not been observed in IPCC. While the cellular crescents showed diverse characteristics in both morphology and immunostaining in the control group. Therefore, these results indicated that IPCC is a sort of ischemic reactive hyperplasia and associated with sclerosis, stenosis, or obstruction of adjacent afferent arterioles, which is clearly different from cellular crescents result from glomerulonephritis.

    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

    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.

    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 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.

    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.

  8. 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.

    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.

    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.

    The Fermi Gamma-ray Space Telescope was launched into orbit in June 2008, and is conducting a multi-year gamma-ray all-sky survey, using the main instrument on Fermi, the Large Area Telescope (LAT). Fermi began its science mission in August 2008, and has now been operating for almost 4 years. The SLAC National Accelerator Laboratory hosts the LAT Instrument Science Operations Center (ISOC), which supports the operation of the LAT in conjunction with the Mission Operations Center (MOC) and the Fermi Science Support Center (FSSC), both at NASA's Goddard Space Flight Center. The LAT has a continuous output data rate of about 1.5 Mbits per second, and data from the LAT are stored on Fermi and transmitted to the ground through TDRS and the MOC to the ISOC about 10 times per day. Several hundred computers at SLAC are used to process LAT data to perform event reconstruction, and gamma-ray photon data are subsequently delivered to the FSSC for public release with a few hours of being detected by the LAT. We summarize the current status of the LAT, and the evolution of the data processing and monitoring performed by the ISOC during the first 4 years of the Fermi mission, together with future plans for further changes to detected event data processing and instrument operations and monitoring.

    While reports showing a link between prenatal androgen exposure and human gender role behavior are consistent and the effects are robust, associations to gender identity or cross-gender identification are less clear. The aim of the current study was to investigate potential cross-gender identification in girls exposed prenatally to high concentrations of androgens due to classical congenital adrenal hyperplasia (CAH). Assessment included two standardized measures and a short parent interview assessing frequency of behavioral features of cross-gender identification as conceptualized in Part A of the diagnostic criteria for gender identity disorder (GID) in the DSM-IV-TR. Next, because existing measures may have conflated gender role behavior with gender identity and because the distinction is potentially informative, we factor analyzed items from the measures which included both gender identity and gender role items to establish the independence of the two constructs. Participants were 43 girls and 38 boys with CAH and 41 unaffected female and 31 unaffected male relatives, aged 4- to 11-years. Girls with CAH had more cross-gender responses than female controls on all three measures of cross-gender identification as well as on a composite measure of gender identity independent of gender role behavior. Furthermore, parent report indicated that 5/39 (12.8 %) of the girls with CAH exhibited cross-gender behavior in all five behavioral domains which comprise the cross-gender identification component of GID compared to 0/105 (0.0 %) of the children in the other three groups combined. These data suggest that girls exposed to high concentrations of androgens prenatally are more likely to show cross-gender identification than girls without CAH or boys with and without CAH. Our findings suggest that prenatal androgen exposure could play a role in gender identity development in healthy children, and may be relevant to gender assignment in cases of prenatal hormone disruption

    The aim of this study was to investigate the safety and effectiveness of tadalafil 5 mg once daily (quaque die [everyday], QD) among Korean men with benign prostatic hyperplasia (BPH)/lower urinary tract symptoms (LUTS) in a real-world clinical setting. This was a single-country, prospective, observational cohort study in which patients newly prescribed tadalafil 5 mg QD for the treatment of BPH/LUTS were followed-up for 12±2 or 24±2 weeks, or to the last treatment, during post-marketing surveillance. Safety was evaluated in terms of the frequency of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs). Effectiveness was assessed by changes in the International Prostate Symptom Score (IPSS) from baseline to each endpoint. All patients receiving ≥1 dose of tadalafil 5 mg QD (N=637) were included in the safety population. Two percent of patients (n=13) experienced 15 TEAEs of mild (n=10; 66.7%) or moderate (n=5; 33.3%) severity. No severe TEAEs and no SAEs were reported. Effectiveness evaluations included all patients receiving tadalafil who had both baseline and endpoint observations (12-week, N=265; 24-week, N=44). Compared with baseline, the mean IPSS total score (±standard error) significantly improved by 4.7±0.3 and 6.4±0.7 points at the 12- and 24-week endpoints, respectively (peffective in Korean men with BPH/LUTS in a real-world clinical setting.

Treatment Satisfaction Scale-BPH (TSS-BPH) responses were assessed based on median treatment differences using the van Elteren test. Overall treatment satisfaction was greater for tadalafil vs placebo (P = 0.005), based on greater satisfaction with efficacy (P = 0.003); neither overall treatment satisfaction nor satisfaction with efficacy was greater for tamsulosin vs placebo (P ≥ 0.409). For individual questions, 66.5% of men rated tadalafil treatment as 'effective/very effective' (Question 1, Q1) vs placebo (P = 0.011), 72.6% would 'definitely/probably recommend their treatment' (Q3; P = 0.043), 71.8% were generally 'very satisfied/satisfied with their medication' (Q8; P BPH by baseline age (≤65/>65 years), history of erectile dysfunction (yes/no), LUTS/BPH severity (IPSS

    2015-01-01

    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.

    Patient: Female, 4 Final Diagnosis: Tumoral calcinosis Symptoms: Hard immobile mass Medication: — Clinical Procedure: — Specialty: Surgery Objective: Congenital defects Background: Tumoral calcinosis is an uncommon condition associated with the deposition of painless calcific masses. It is more common in childhood or early adolescence of African-American females. Case Report: We present a case of a 4-year-old girl with tumoral calcinosis treated surgically. The case is rather rare in terms of the age of the patient and the localization of the masses (gluteal site). In our patient, the biochemical findings were normal, except for hyperphosphatemia and elevated alkaline phosphatase. Conclusions: Total excision appears to lead to a good clinical outcome and a low incidence of local relapse. PMID:24644527

    To describe the prevalence of doping and its progression in a cohort of preadolescent athletes during a 4-year follow-up. Prospective cohort study. Self-questionnaire survey. All of the pupils entering the first year of secondary school (sixth grade) in the Vosges Département (east France) and followed for 4 years. Drug use (prohibited substances, tobacco, alcohol, cannabis), intention to use, reported health hazards, perceived drug effectiveness, self-esteem, trait anxiety. At the beginning of the study, 1.2% (95% CI 0.8 to 1.6) stated that they had taken doping agents at least once in the preceding 6 months, and this had risen to 3.0% (95% CI 2.3-3.7) 4 years later (pself-esteem and trait anxiety. The results show that doping does exist in preadolescent athletes who train every day. This fact should to be taken into account in preventive actions.

    Full Text Available Introduction: Oral motor disorders, such as speech and swallowing disorders, often occur in children. Generally parents complain that children refuse to eat hard food, drooling excess, and unable to speak clearly. Oral motor disturbance can occur due to the unavailability of maturation of oral motor structure. This study was aimed to determine the description of oral motor disturbance in children aged 2-4 years in some Integrated Health Service (Posyandu in Bandung. Methods: Descriptive research with cross sectional design. The study was conducted on 100 parents who came to six posyandu in Bandung by using questionnaires through guided interviews by researchers. Samples were taken using multistage random sampling technique. The results will be presented in tabular form and assessed using Arikunto standard criteria. Results: The results showed a low percentage in oral motor disturbances. Indicators of oral motor disturbance in children aged 2 - 4 years included in either category. As for children who have oral motor disorders exhibit various manifestations. Conclusion: The description of oral motor disorders in children aged 2 - 4 years in Posyandu in Bandung was shown by various manifestations. Based on the number of populations taken, oral motor disorders in children aged 2-4 years included into either category.

    responders by Q(max) was 46.6%, 46.5%, and 40.5% in the silodosin, tamsulosin, and placebo treatment groups, respectively. This difference was not statistically significant (p = 0.155 silodosin vs placebo and p = 0.141 tamsulosin vs placebo). Active treatments were well tolerated, and discontinuation rates due to adverse events were low in all groups (2.1%, 1.0%, and 1.6% with silodosin, tamsulosin, and placebo, respectively). The most frequent adverse event with silodosin was a reduced or absent ejaculation during orgasm (14%), a reversible effect as a consequence of the potent and selective a(1A)-adrenoreceptor antagonism of the drug. The incidence was higher than that observed with tamsulosin (2%); however, only 1.3% of silodosin-treated patients discontinued treatment due to this adverse event. Silodosin is an effective and well-tolerated treatment for the relief of both voiding and storage symptoms in patients with lower urinary tract symptoms suggestive of bladder outlet obstruction thought to be associated with benign prostatic hyperplasia. Its overall efficacy is not inferior to tamsulosin. Only silodosin showed a significant effect on nocturia over placebo.

    Bennett, Samuel C; Goonewardene, Mithran S

    2016-05-01

    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.

    The National Practitioner Data Bank became operational September 1, 1990, as a flagging system to identify health care practitioners who may have been involved in incidents of medical incompetence. Query volumes have grown substantially over the Data Bank's first 4 years of operation. The greatest increase has come in the number of voluntary queries. By the end of 1994, the Data Bank had processed more than 4.5 million requests for information on practitioners, more than 1.5 million of which were received in 1994 alone. The proportion of queries for which the Data Bank contains information on the practitioner in question has grown as the Data Bank has come to contain more reports. During 1994, 7.9 percent of queries were matched. The Data Bank contained more than 97,500 reports at the end of 1994. More than 82 percent of the reports concerned malpractice payments. Licensure reports made up the bulk of the rest. Physicians predominate in reports, accounting for slightly more than 76 percent of the total. The remainder are related to dentists (16 percent) and all other types of practitioners (8 percent). Since reporting of adverse actions is mandatory only for physicians and dentists, the proportion of reports attributable to these types of practitioners is higher than it would be if adverse action reporting requirements were uniform for all practitioners. State malpractice payment rates and adverse action rates vary widely, but a State's rate in any given year is highly correlated with its rate in any other year. State malpractice rates are not strongly correlated with adverse action rates, neither are the rates for physicians strongly correlated with those for dentists. There is a weak tendency for States with smaller physician populations to have higher levels of licensure and privileging actions.

    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.

    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.

    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.)

    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.

  16. The epigenetic factor PCAF regulates vascular inflammation and is essential for intimal hyperplasia development.

    Directory of Open Access Journals (Sweden)

    Rob C M de Jong

    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.

    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.

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

    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.

    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.

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.

    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 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.

    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.

    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.

    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.

    Full Text Available Abstract Background Management of endometrial precancerous lesions has been of much debate due to inconsistencies in their classification, natural history and histologic diagnosis. Endometrial hyperplasia constitutes a wide range of histomorphologic features associated with high intra and interobserver diagnostic variability. Although traditional microscopic diagnosis is by far the most applicable method and the gold standard for histomorphologic diagnosis, digitized image analysis has been used as a powerful adjunct to maximize the histologic data retrieval and to add some detailed objective criteria for correct diagnosis in difficult cases. Methods A series of 100 endometrial curettage specimens with diagnosis of endometrial hyperplasia or well differentiated adenocarcinoma were blindly reviewed by 5 pathologists; their intra and interobserver reproducibility determined and further compared to the objective morphometric data i.e. D-score and volume percent of stroma (VPS. Results The results were assessed using the weighted kappa statistics. Mean intraobserver kappa value was 0.8690 (99.44% agreement. Mean interobserver kappa values by diagnostic category were: simple hyperplasia without atypia: 0.7441; complex hyperplasia without atypia: 0.3379; atypical hyperplasia: 0.3473, and well-differentiated endometrioid carcinoma: 0.6428; with a kappa value of 0.5372 for all cases combined. Interobserver agreement was in substantial rate for simple hyperplasia (SH and well differentiated adenocarcinoma (WDA but was in fair limit for complex hyperplasia (CH and atypical hyperplasia (AH. Intraobserver agreement was almost perfect. The specimens were divided in two groups according to the computerized morphometric analysis: Endometrial Hyperplasia (EH ( D Score ≥ 1 or VPS ≥ 55% and Endometrial Intraepithelial Neoplasia (EIN (D-Score Conclusion It may be necessary to make some revisions in WHO classification for endometrial hyperplasia and

    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.

    Full Text Available The use of testosterone to treat the symptoms of late-onset hypogonadal men has increased recently due to patient and physician awareness. However, concerns regarding the effect of testosterone on the prostate, in particular any possible effect on the risk of prostate cancer have prompted further research in this regard. Surprisingly, numerous retrospective or small, randomized trials have pointed to a possible improvement in male lower urinary tract symptoms (LUTS in patients treated with testosterone. The exact mechanism of this improvement is still debated but may have a close relationship to metabolic syndrome. For the clinician, the results of these studies are promising but do not constitute high levels of evidence. A thorough clinical examination (including history, examination and laboratory testing of testosterone should be undertaken before considering the diagnosis of late-onset hypogonadism or instigating treatment for it. Warnings still remain on the testosterone supplement product labels regarding the risk of urinary retention and worsening LUTS, and these should be explained to patients.

  16. Insights Gained From 4 Years of EOSDIS User Surveys

    The Earth Observation System Data and Information System (EOSDIS) is a large, complex data system currently supporting over 18 operational NASA satellite missions including the flagship EOS missions: Terra, Aqua, and Aura. A critical underpinning for management of EOSDIS is developing a thorough knowledge of the EOSDIS user community and how they use the EOSDIS products in their research. It is important to know whether the system is meeting the users' needs and expectations. Thus, in 2004 NASA commissioned a comprehensive survey to determine user satisfaction using the American Customer Satisfaction Index (ACSI) approach. NASA has continued to survey users yearly since. Users continue to rate EOSDIS systems and services highly as the EOSDIS ACSI score has outperformed both the averages for U.S. companies and for Federal Agencies. In addition, users' comments have provided valuable insight into the effect of data center processes on users' experiences. Although their satisfaction has remained high, their preferences have changed with the rapid advances in web-based services. We now have four years of data on user satisfaction from these surveys. The results of each survey highlight areas that, if improved, could lead to increased user satisfaction, including overall product quality, product documentation, and product selection and ordering processes. This paper will present the survey results and how they compare from year to year.

    Our studies have shown that endotoxin intratracheally instilled into the rat lung induces proliferation of alveolar type II cells. In that study, the alveolar type II cells. In that study, the alveolar type II cell hyperplasia occurred 2 d after instillation of endotoxin and persisted for a further 2 d. After hyperplasia, the lung remodeled and returned to a normal state within 24-48 h. Understanding the mechanisms involved in the remodeling process of this transient hyperplasia may be useful to identify molecular changes that are altered in neoplasia. The purpose of the present study was to corroborate induction of epithelial cell hyperplasia by endotoxin and to delineate mechanisms involved in tissue remodeling after endotoxin-induced alveolar type II cell hyperplasia. In conclusion, immonostaining with cyclin D1 and cytokeratin shows that endotoxin induced epithelial cell proliferation and resulted in hyperplasia in the lung which persisted through 4 d post-instillation.

    Girls with congenital adrenal hyperplasia (CAH) diagnosed at birth have some masculine behaviors but rarely convert to male gender. In developing countries, however, diagnosis and treatment (with secondary androgen suppression) are delayed. We aimed to assess effect of delayed treatment of CAH on gender identity. As part of a cross-sectional, case-control study of children with disorders of sex development (DSD), there were 11 patients with CAH. Patients and caregivers answered a questionnaire about gender identity, and behavior was assessed by observing toy play. Patients were examined for Prader score and gender identity. Of 11 CAH patients initially raised as girls, 3 (27%) had converted to male gender at presentation (5, 9, 9years) (Prader 3, 4, 4). Of the remaining 8 patients, one 4-year-old (Prader 2) had a male gender identity score. The remaining girls (2-13years, mean 8.1) (Prader 1-3) had gender identity scores in the female range. One third (4/11) of CAH patients presenting in mid-childhood had male gender identity scores, and ¾ had assumed male gender role. Although social and cultural factors are important in developing countries, this result suggests that delayed treatment may trigger male gender identity, and delayed female genital surgery may be unwise.

    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.

    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

    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.

    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)

    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.

    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

    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

    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.

    1993-01-01

    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

    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.

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

    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.

    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.

    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.

    To evaluate the long-term outcomes of aspheric corneal wavefront ablation profiles for excimer laser retreatment. Eighteen eyes that had previously undergone LASIK or photorefractive keratectomy (PRK) were retreated with LASIK using the corneal wavefront ablation profile. Custom Ablation Manager (SCHWIND eye-tech-solutions, Kleinostheim, Germany) software and the ESIRIS flying spot excimer laser system (SCHWIND) were used to perform the ablations. Refractive outcomes and wavefront data are reported up to 4 years after retreatment. Pre- and postoperative data were compared with Student t tests and (multivariate) correlation tests. P<.05 was considered statistically significant. A bilinear correlation of various postoperative wavefront aberrations versus planned correction and preoperative aberration was performed. Mean manifest refraction spherical equivalent (MRSE) before retreatment was -0.38±1.85 diopters (D) and -0.09±0.22 D at 6 months and -0.10±0.38 D at 4 years postoperatively. The reduction in MRSE was statistically significant at both postoperative time points (P<.005). Postoperative aberrations were statistically lower (spherical aberration P<.05; coma P<.005; root-mean-square higher order aberration P<.0001) at 4 years postoperatively. Distribution of the postoperative uncorrected distance visual acuity (P<.0001) and corrected distance visual acuity (P<.01) were statistically better than preoperative values. Aspheric corneal wavefront customization with the ESIRIS yields visual, optical, and refractive results comparable to those of other wavefront-guided customized techniques for the correction of myopia and myopic astigmatism. The corneal wavefront customized approach shows its strength in cases where abnormal optical systems are expected. Systematic wavefront customized corneal ablation appears safe and efficacious for retreatment cases. Copyright 2012, SLACK Incorporated.

    To explore employment status, work limitations, and productivity loss after mild traumatic brain injury (TBI). Inception cohort study over 4 years. General community. Adults (N=245; >16y at the time of injury) who experienced a mild TBI and who were employed prior to their injury. Not applicable. Details of the injury, demographic information, and preinjury employment status were collected from medical records and self-report. Symptoms and mood were assessed 1 month postinjury using the Rivermead Post-Concussion Symptom Questionnaire and the Hospital Anxiety and Depression Scale. Postinjury employment status and work productivity were assessed 4 years postinjury using the Work Limitations Questionnaire. Four years after mild TBI, 17.3% of participants had exited the workforce (other than for reasons of retirement or to study) or had reduced their working hours compared with preinjury. A further 15.5% reported experiencing limitations at work because of their injury. Average work productivity loss was 3.6%. The symptom of taking longer to think 1 month postinjury significantly predicted work productivity loss 4 years later (β=.47, t=3.79, P≤.001). Although changes in employment status and difficulties at work are likely over time, the results indicate increased unemployment rates, work limitations, and productivity loss in the longer term after a mild TBI. Identification of cognitive difficulties 1 month after TBI in working aged adults and subsequent interventions to address these difficulties are required to facilitate work productivity.

    Victor Hugo Maciel Meloni

    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.

    To investigate whether a fixed-dose combination (FDC) of 0.5 mg dutasteride and 0.4 mg tamsulosin is more effective than watchful waiting with protocol-defined initiation of tamsulosin therapy if symptoms did not improve (WW-All) in treatment-naïve men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression. This was a multicentre, randomised, open-label, parallel-group study (NCT01294592) in 742 men with an International Prostate Symptom Score (IPSS) of 8-19, prostate volume ≥30 mL and total serum PSA level of ≥1.5 ng/mL. Patients were randomised to FDC (369 patients) or WW-All (373) and followed for 24 months. All patients were given lifestyle advice. The primary endpoint was symptomatic improvement from baseline to 24 months, measured by the IPSS. Secondary outcomes included BPH clinical progression, impact on quality of life (QoL), and safety. The change in IPSS at 24 months was significantly greater for FDC than WW-All (-5.4 vs -3.6 points, P tamsulosin. FDC therapy with dutasteride and tamsulosin, plus lifestyle advice, resulted in rapid and sustained improvements in men with moderate BPH symptoms at risk of progression with significantly greater symptom and QoL improvements and a significantly reduced risk of BPH progression compared with WW plus initiation of tamsulosin as per protocol. © 2015 The Authors.

    The aim of this paper is to share our experience and observations in running the Universal Neonatal Hearing Screening Program on a national level, present results and indicate some problems that have arisen during these 4 years. Polish Universal Neonatal Hearing Screening Program started back in 2002 in all neonatal units in Poland. Implemented testing methods consisted of test of transient evoked otoacoustic emission (TEOAE) performed in all new born children in their first 2-3 days of life and auditory brainstem response testing (ABR) conducted on children, who did not meet the TEOAE pass criteria. Additional questionnaire registered information on ototoxic drugs and family history of hearing impairment in every newborn. Diagnosed children were further referred for treatment and rehabilitation. After 4 years of running the program (between 2003 and 2006) a total number of 1,392,427 children were screened for hearing impairment, what stands for 96.3% of all delivered babies, registered in Poland. The screening program enabled to identify and refer for further treatment 2485 children with various types of hearing loss, 312 with profound (0.02% of population) and 145 with severe sensorineural hearing loss (0.11% of population). Our results indicate the accuracy of newborn hearing screening which remain an issue. Although improvement is needed in both intervention systems and diagnostic follow-up of hospitals, the Polish Universal Neonatal Hearing Program fully has achieved the main goal, the identification and treatment of hearing impaired children.

    The importance of tubular epithelial hyperplasia in polycystic kidney diseases has become apparent during the last decade. Micropapillary hyperplasia occurs in autosomal dominant polycystic kidney disease, in localized cystic disease, and in acquired cystic disease. Neoplastic or severely dysplastic epithelial hyperplasia occurs in von Hippel-Lindau disease. A histopathologically distinctive epithelial hyperplasia occurs in tuberous sclerosis.

    We report a case of lymphangioma circumscriptum (cavernous lymphangioma with epithelial hyperplasia) in a 12-year-old girl, presenting as a papillary tumor on the right dorsal side of her tongue. Microscopic examination found cavernous vascular channels lined by a single layer of CD31(+), podoplanin-positive, CD34(-) endothelial cells that occupied the papillary lamina propria and were accompanied by epithelial hyperplasia. A review of the literature on oral vascular tumors with epithelial hyperplasia, namely, lymphangioma circumscriptum and angiokeratoma, provided information that draws into question the use of these terms.

    Full Text Available Hysteroscopy is a new and precise method for evaluating of uterus, so it is valuable in evaluating infertile women. In 18 months, 363 hysteroscopies were done on patients who were visited in IVF center of Shariati Hospital for treatment of infertility. Incidence of abnormal hysteroscopy was 18%. 32% of these abnormal hysteroscopies was endometrial hyperplasia. In evaluating of laparoscopy and other factors of these patients there was a statistically significant relation between diagnosis of PCOD (polycystic ovary disease and endometrial hyperplasia (P<0.008, but there is no significant relation between other diagnoses like endometriosis and endometrial hyperplasia (P<0.4.

    Marrow hyperplasia is a sequela of sickle cell anemia (SCA) and may be seen in the skull in children after 5 years of age. 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.)

    2016-01-01

    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".

    Full Text Available The aim of this study was to investigate if children’s early responsiveness towards social partners is developmentally related to their growing concept of self, as reflected in their mirror self recognition (MSR and delayed self recognition (DSR. Thus, a longitudinal study assessed infants' responsiveness (e.g., smiling, gaze towards social partners during the still-face task and a social imitation game and related it to their emerging MSR and DSR. Thereby, children were tested at regular time points from 9 months to 4 years of age. Results revealed significant predictive relations between children’s responsiveness towards a social partner in the still-face task at 9 months and their MSR at 24 months. Further, interindividual differences in children’s awareness of and responsiveness towards being imitated in a social imitation game at 12 months proved to be the strongest predictor of children’s DSR at 4 years, while some additional variance was explained by MSR at 24 months and verbal intelligence. Overall, findings suggest a developmental link between children’s early awareness of and responsiveness towards the social world and their later ability to form a concept of self.

    In the young population, spontaneous rupture of Achilles tendon is very rare. The big hematoma is also rare finding of the Achilles tendon partial rupture. It is usually seen with complete rupture. We presented imaging findings of 4 years follow up of the spontaneous partial rupture of Achilles tendon presenting with giant expanding hematoma and mimicking complete rupture radiologically. We discussed the alterations of tendon signal intensity and result of conservative therapy after partial rupture with big hematoma in the long term. A 29 year-old man, applied with pain and swelling in the retrocalcaneal region of left ankle. He did not have chronic metabolic disease. He was not active in physical activities. X-ray radiograms were normal. At magnetic resonance images (MRI), there was an intratendinous big hematoma, subcutanous fat planes were edematous around tendon. The diagnosis was partial rupture and giant hematoma. Hematoma was drained. The conservative treatment was applied and his complaints disappeared. After treatment, approximately 4 years later, control MRI showed thickened and hypointense tendon in all images. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

    The study objective is to evaluate the results of our surgical technique for children with congenital adrenal hyperplasia and ambiguous genitalia at the University Hospital of Heidelberg, Department of Paediatric Surgery. The records of 19 patients with congenital adrenal hyperplasia treated between 1972 and 2004 were reviewed with respect to age at surgery, operative procedures and outcome. We describe the recession clitoroplasty technique currently used in our hospital and highlight the importance of short and long-term follow-up results with respect to appearance, position and size of the clitoris and quality of the vagina. One-stage recession clitoroplasty and vaginoplasty gives very satisfactory cosmetic and functional results, with few complications and a reduced need for secondary surgical interventions. The results of this study support the assumption that total correction can be achieved through a single-stage operation, performed in infancy.

    Purpose: To identify and compare magnetic resonance imaging (MRI) characteristics, with and without intravenous contrast medium, of cavernous synovial hemangiomas and cystic synovial hyperplasia. Material and Methods: Four cases of cavernous synovial hemangioma and five of cystic synovial hyperplasia of the knee were studied retrospectively. The patients (5 F and 4 M; 15-25 years of age) all had long-standing knee pain. At clinical examination we observed elastic swelling and pain without significant joint effusion. The patients underwent conventional radiography and MRI without and following intravenous contrast medium before arthroscopic biopsy. Results: The radiographs were interpreted as negative in all patients. MRI examination without contrast medium revealed a similar multicystic appearance for both lesions. Following intravenous contrast agent administration, cavernous synovial hemangiomas demonstrated avid, rather homogenous enhancement, whereas cystic synovial hyperplasia demonstrated less intense, peripheral enhancement only. Arthroscopy with histological examination of the lesions confirmed the MRI diagnosis in every case. Conclusion: In our experience, cavernous synovial hemangioma and cystic synovial hyperplasia have a similar appearance on unenhanced MRI, but can be reliably differentiated on the basis of enhancement characteristics following intravenous contrast administration.

    Creation of an autologous arteriovenous fistula (AVF) for vascular access in haemodialysis is the modality of choice. However neointimal hyperplasia and loss of the luminal compartment result in AVF patency rates of ~60% at 12months. The exact cause of neointimal hyperplasia in the AVF is poorly understood. Vascular trauma has long been associated with hyperplasia. With this in mind in our rabbit model of AVF we simulated cannulation autologous to that undertaken in vascular access procedures and observed significant neointimal hyperplasia as a direct consequence of cannulation. The neointimal hyperplasia was completely inhibited by topical transdermal delivery of the non-steroidal anti-inflammatory (NSAID) diclofenac. In addition to the well documented anti-inflammatory properties we have identified novel anti-proliferative mechanisms demonstrating diclofenac increases AMPK-dependent signalling and reduced expression of the cell cycle protein cyclin D1. In summary prophylactic transdermal delivery of diclofenac to the sight of AVF cannulation prevents adverse neointimal hyperplasic remodelling and potentially offers a novel treatment option that may help prolong AVF patency and flow rates.

    Full Text Available Objective: To examine the relationship between benign prostatic hyperplasia (BPH and the presence of lower urinary tract stones. Methods: We retrospectively reviewed the records of men with lower urinary tract stones who presented to three clinical centers in Korea over a 4-year period. We divided the patients into two groups based on the location of urinary stones: Group 1 (bladder calculi and Group 2 (urethral calculi. We compared the characteristics of both groups and performed univariate and multivariate analyses with a logistic regression model to investigate the relationship between BPH and lower urinary tract stones. Results: Of 221 patients, 194 (87.8% had bladder calculi and 27 (12.2% had urethral calculi. The mean age of Group 1 was higher than that of Group 2 (68.96 ± 12.11 years vs. 55.74 ± 14.20 years, p < 0.001. The mean prostate volume of Group 1 was higher than that of Group 2 (44.47 ± 27.14 mL vs. 24.70 ± 6.41 mL, respectively, p < 0.001. Multivariate logistic regression showed that age (OR = 1.075, 95%CI: 1.023–1.129 and prostate volume (OR = 1.069, 95%CI: 1.017–1.123 were independently associated with increased risk for bladder calculi. Upper urinary tract stones and/or hydronephrosis conferred a 3-fold risk for urethral calculi (OR = 3.468, 95%CI: 1.093–10.999. Conclusion: Age and prostate volume are independent risk factors for bladder calculi. In addition, men with upper urinary tract disease are at greater risk for urethral calculi, which may migrate from the upper urinary tract rather than from the bladder.

    Full Text Available ABSTRACT: Introduction & Objective: Results of different studies show that a relatively large number of healthcare services offered are inappropriate or unnecessary. Benign prostatic hyperplasia is a benign enlargement of the prostate gland. Clinical features of this disease are one of the most common problems encountered by elderly males. The aim of this study was to assess the appropriateness of benign prostatic hyperplasia surgery. Materials & Methods: In this qualitative study which was conducted in 2008-9, in Tehran University of Medical Sciences, the RAN/UCLA method was used, which was designed in 1980 by the RAND institute and the University of California in Los Angeles. Regarding the stages of our method, scenarios and indications for benign prostatic hyperplasia surgery were chosen from the latest approved scientific resources and subsequently sent to urology specialists, who were chosen as members of the specialized panel. Panel members gave scores ranging from 1 to 9 to each indication and scenario based on scientific resources, clinical experiences and patient’s condition in two separate panel sessions. After compilation, the indications were finally grouped as appropriate, equivocal, and inappropriate so that they could be used to determine appropriateness of benign prostatic hyperplasia surgery in hospitals. In this study, the most suitable and most approved clinical guidelines related to benign prostatic hyperplasia, the Guidelines Evaluation and Research Appraisal (AGREE were used.The selected guidelines were used as scientific resources for choosing the indications of benign prostatic hyperplasia surgery. SPSS version 16 and kappa weighted value were used in analysis process of the study. Results: Out of 282 scenarios grouped as 9 conditions related to benign prostatic hyperplasia surgery, which were extracted from scientific sources, 73 cases (25.9% were considered as appropriate, 14 cases (5% as equivocal and 7 cases (2

    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.

    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.

    The histopathology of papillary thyroid hyperplasia and papillary thyroid carcinoma is similar enough to cause a diagnostic dilemma in a few cases. Both lesions may have papillary fronds with fibrovascular cores, nuclear crowding, and nuclear anisocytosis. Formalin- fixed paraffin-embedded tissues from 30 randomly selected patients with papillary thyroid hyperplasia and an equal number from patients with papillary thyroid carcinoma were analyzed for expression of cytokeratin 19 (CK19), galectin-3, and HBME-1. Cases of papillary thyroid carcinoma had moderate to strong CK19, galectin-3, and HBME-1 reactivity although both CK19 and galectin-3 showed positive staining in a significant number of nonneoplastic thyroid cases. HBME-1 was uncommon in the nonneoplastic cases. These results indicate that HBME-1 may be useful in helping to distinguish papillary thyroid carcinoma from hyperplasia in diagnostically difficult cases.

    Full Text Available Topicality. The most common disease of the men’s urogenital system is Benign Prostatic Hyperplasia. Causation of disease - not fully understood. There are several theories of emergence benign prostatic hyperplasia, major importance given to age-related disorders of hormonal metabolism. According to the World Health Organization (WHO information BPH is found in 11.3% in men aged 40-49 years, and in 81,4% at the age of 80 years. Currently, the main treatment of benign prostatic hyperplasia is operational. Each method of surgical treatment of BPH has its indications and contraindications. The indications for open prostatectomy is the presence of bladder stones, bladder tumors and bladder diverticulum, a large volume of a gland (80 cm3 or more. Endoscopic intervention (without opening of the bladder is performed if there is a serious general comorbidities, which does not allow to carry out major surgery if prostate volume does not exceed 80 cubic centimeters. It can be done in a relatively young age and if patient has desirability of sexual function preserving. Postoperative results of treatment of patients in both groups, overall survival, duration of the postoperative period, the number of postoperative complications and rehabilitation of patients in the postoperative period are based on the method of surgical treatment. The aim of our research was to make a comparative analysis of the effectiveness of transurethral resection of the prostate (TURP and open prostatectomy in patients with BPH.

    Cerebral candidiasis is a devastating disease which contributes to a high mortality. Most of the cerebral candidiasis are never microbiologically or radiologically confirmed. In this case, a 4-year-old boy who developed cerebral candidiasis was successfully rescued and presented. The diagnosis of cerebral candidiasis was established based on both microbiologic and radiologic examinations. The pathogen was revealed to be Candida albicans by cerebrospinal fluid and central venous catheter cultures, and the cerebral involvement was recorded by series head magnetic resonance imaging (MRI) with an appearance of special encephalitis demonstrated. The imaging studies played a critical role throughout the diagnosis and treatment. Familiarity with the imaging findings in the appropriate clinical setting may result in a heightened level of awareness of this infection and, consequently, in earlier diagnosis and treatment. © The Author(s) 2014.

    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.

    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 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).

    To describe the results obtained in a neonatal screening program after its implementation and to assess the clinical and molecular profiles of confirmed and suspicious congenital adrenal hyperplasia cases. A cross-sectional study was conducted. Newborns with suspected disease due to high 17-hydroxyprogesterone levels and adjusted for birth weight were selected. Classical congenital adrenal hyperplasia (salt-wasting and simple virilizing forms) was diagnosed by an increase in 17-hydroxyprogesterone levels as confirmed in the retest, clinical evaluation, and genotype determined by SNaPshot and multiplex ligation-dependent probe amplification. After 24 months, 15 classic congenital adrenal hyperplasia cases were diagnosed in a total of 217,965 newborns, with an estimated incidence of 1:14,531. From 132 patients, seven non-classical and 14 heterozygous patients were screened for CYP21A2 mutations, and 96 patients presented false positives with wild type CYP21A2. On retest, increased 17-hydroxyprogesterone levels were found in classical congenital adrenal hyperplasia patients and showed significant correlation with genotype-related classical genital adrenal hyperplasia. The most frequent mutations were IVS2-13A/C>G followed by gene deletion or rearrangement events in the classical form. In non-classical and heterozygous diseases, p.Val282Leu was the most common mutation. The results underscore the effectiveness of congenital adrenal hyperplasia neonatal screening in the public health system and indicate that the adopted strategy was appropriate. The second sample collection along with genotyping of suspected cases helped to properly diagnose both severe and milder cases and delineate them from false positive patients. Copyright © 2018.

    The radiographic pattern of nodular lymphoid hyperplasia, perhaps better called the lymphoid follicular pattern, has variously been described as an indication of disease and as a normal variant in the adult, with current opinion favoring the latter. We report 3 cases wherein this pattern resulted from definite pathologic processes: sarcoidosis, infectious mononucleosis, and Crohn's disease. Although usually of no pathological significance, the benign follicular pattern may reflect a variety of diseases.

    Full Text Available Objective. To report an unusual case of ovarian Leydig cell hyperplasia resulting in virilization in a postmenopausal woman. Methods. Patient’s medical history and pertinent literature were reviewed. Results. A 64-year-old woman presented with virilization with worsening hirsutism, deepening of her voice, male musculature, and male pattern alopecia. Her pertinent past medical history included type 1 diabetes, hyperlipidemia, and hypertension. Her pertinent past surgical history included hysterectomy due to fibroids. On further work-up, her serum total testosterone was 506 ng/dL (nl range: 2–45 and free testosterone was 40 pg/mL (nl range: 0.1–6.4. After ruling out adrenal causes, the patient underwent an empiric bilateral oophorectomy that showed Leydig cell hyperplasia on pathology. Six weeks postoperatively, serum testosterone was undetectable with significant clinical improvement. Conclusion. Postmenopausal hyperandrogenism can be the result of numerous etiologies ranging from normal physiologic changes to ovarian or rarely adrenal tumors. Our patient was found to have Leydig cell hyperplasia of her ovaries, a rarely reported cause of virilization.

    Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate that results in obstructive lower urinary tract symptoms. Plant extracts are frequently used to treat BPH rather than therapeutics that can cause severe side effects. ACTICOA() (Ba0rry Callebaut France, Louviers, France) powder (AP) is a cocoa polyphenolic extract, and we have shown in a previous study that oral treatment with AP prevented prostate hyperplasia. This study investigated whether AP could improve established prostate hyperplasia using the same testosterone propionate (TP)-induced prostate hyperplasia model in rats. Male Wistar-Unilever rats were randomly divided in four groups of 12 rats: one group injected with corn oil and orally treated with the vehicle (negative control) and three groups injected subcutaneously with TP and orally treated with the vehicle (positive control) or AP at 24 (AP24) and 48 (AP48) mg/kg/day. Treatments started 1 week after the start of the induction of prostate hyperplasia and lasted for 2 weeks. The influence of TP and AP on body weights, food and water consumptions, plasma polyphenolic concentration, and serum dihydrotestoterone (DHT) level of rats was examined. At completion of the study, rats were sacrificed, and the prostates were removed, cleaned, and weighed. The prostate size ratio (prostate weight/rat body weight) was then calculated. TP significantly influenced the body weight gain of the rats and their food and water consumptions, while AP reduced significantly these differences in a dose-dependent manner. AP significantly reduced serum DHT level and prostate size ratio in comparison with positive controls also dose-dependently. In conclusion, AP orally administered was effective for reducing established prostate hyperplasia, especially at the dose of 48 mg/kg/day.

    Health-related factors are part of the multifactorial background of dysphonia in children. Respiratory tract infections affect the same systems and structures that are used for voice production. The purpose of this study was to investigate if the number of respiratory tract infections or the viral etiology were significant predictors for a more hoarse voice quality. The participants were 4-year-old children who participated in the multidisciplinary STEPS study (Steps to the Healthy Development and Well-being of Children) where they were followed up from pregnancy or birth to 4 years of age. Data were collected through questionnaires and a health diary filled in by the parents. Some of the children were followed up more intensively for respiratory tract infections during the first 2 years of life, and nasal swab samples were taken at the onset of respiratory symptoms. Our participants were 489 of these children who had participated in the follow-up for at least 1 year and for whom data on respiratory tract infections and data on voice quality were available. The number of hospitalizations due to respiratory tract infections was a significant predictor for a more hoarse voice quality. Neither the number of rhinovirus infections nor the number of respiratory syncytial virus infections was statistically significant predictors for a more hoarse voice quality. Based on our results, we would suggest including questions on the presence of respiratory tract infections that have led to hospitalization in the pediatric voice anamnesis. Whether the viral etiology of respiratory tract infections is of importance or not requires further research. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    A laparoscopic choledochoduodenostomy (LCDD) may be performed when the common bile duct (CBD) is obstructed by primary or secondary stones or strictures. A biliary bypass procedure has two goals in view. The short-term goal is complete removal of stones and bypass of obstruction and stricture to restore biliary drainage. The long-term goal is preventing a recurrence of the problem. There is debate over the superiority of any one procedure to achieve both goals. Therefore, it may help the practicing clinician to be aware of the success (or failure), on a case-by-case basis, of these procedures. This awareness may help in the choice of technique. To date, since 1991, we have performed 16 LCDDs; however, in this report, we describe our results with LCDD over the last 4 years to emphasize the usefulness of this procedure. We find that it is a safe and effective procedure for treating patients with benign bile duct obstruction, even for those whose condition may be described as complicated or difficult. Evidence is slowly accumulating that LCDD is also successful in promoting long-term biliary drainage. We reviewed our LCDDs done over the past 4 years, documenting our preoperative, intraoperative, and postoperative experience. A successful LCDD was performed on all six patients. None of the patients had postoperative leaks. There was only one death, which was due to the patient's comorbidities and not the procedure itself. The hepatobiliary enzyme levels returned to normal in all of the surviving patients. The average postoperative length of stay was 6 days. With proper selection and adequate laparoscopic experience, LCDD can be performed in a safe and effective way.

    2008-01-01

    A 4-year field trial was established in eastern Sweden to evaluate the effects of organic waste on soil chemical and microbiological variables. A simple crop rotation with barley and oats was treated with either compost from household waste, biogas residue from household waste, anaerobically treated sewage sludge, pig manure, cow manure or mineral fertilizer. All fertilizers were amended in rates corresponding to 100kgNha(-1)year(-1). The effects of the different types of organic waste were evaluated by subjecting soil samples, taken each autumn 4 weeks after harvest, to an extensive set of soil chemical (pH, Org-C, Tot-N, Tot-P, Tot-S, P-AL, P-Olsen, K-AL, and some metals) and microbiological (B-resp, SIR, microSIR active and dormant microorganisms, PDA, microPDA, PAO, Alk-P and N-min) analyses. Results show that compost increased pH, and that compost as well as sewage sludge increased plant available phosphorus; however, the chemical analysis showed few clear trends over the 4 years and few clear relations to plant yield or soil quality. Biogas residues increased substrate induced respiration (SIR) and, compared to the untreated control amendment of biogas residues as well as compost, led to a higher proportion of active microorganisms. In addition, biogas residues increased potential ammonia oxidation rate (PAO), nitrogen mineralization capacity (N-min) as well as the specific growth rate constant of denitrifiers (microPDA). Despite rather large concentrations of heavy metals in some of the waste products, no negative effects could be seen on either chemical or microbiological soil properties. Changes in soil microbial properties appeared to occur more rapidly than most chemical properties. This suggests that soil microbial processes can function as more sensitive indicators of short-term changes in soil properties due to amendment of organic wastes.

    Delivery can be complicated by urinary or anal incontinence (UI or AI). We hypothesized that the mechanisms of injury may differ for UI and AI. Hence, obstetrical risk factors may be specific for different types of incontinence. Data on maternal characteristics were collected at first delivery. Data on incontinence were obtained by a questionnaire completed by 627 women 4 years after first delivery. UI was defined by "Do you have involuntary loss of urine" and AI by "Do you have involuntary loss of flatus or stool". A multinomial logistic regression analysis was conducted to assess risk factors for UI only, AI only, and UI+AI. Twenty-two percent of women reported UI only, 6.5% AI only, and 6.5% both. Risk factors associated with UI only were age (at first delivery)≥ 30 (OR 2.27 [95% CI 1.47-3.49]), pre-existing UI (6.44 [2.19-19.0]) and pregnancy UI (3.64 [2.25-5.91]). Risk factors associated with AI only were length of the second active stage> 20minutes (2.86 [1.15-7.13]) and third degree perineal tear (20.9 [1.73-252]). Significant predictors of UI+AI were age ≥ 30 (2.65 [1.29-5.46]), no epidural (4.29 [1.65-11.1]), third degree perineal tear (20.0 [1.28-314]), and UI before pregnancy (32.9 [9.00-120]). Cesarean delivery was not significantly associated with UI, AI, or UI+AI, although for all three outcomes, the adjusted odds ratios were substantially less than one. We found specific associations between obstetrical risk factors and urinary versus anal incontinence 4 years after first delivery. Our results are consistent with the hypothesis that the underlying mechanisms of injury differ for UI and AI. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Mental health has been reported to be associated with allergy, but only a few cohort studies have assessed if neurodevelopment predicts atopy. To investigate if neurobehavioral status of healthy 4-year-old children was associated with specific immunoglobulin E (IgE) at the same age and skin prick test results 2 years later. A population-based birth cohort enrolled 482 children, 422 of them (87%) provided neurobehavioral data, 341 (71%) had specific IgE measured at the age of 4 years; and 395 (82%) had skin prick tests completed at the age of 6 years. Atopy was defined as IgE levels higher than 0.35 kU/l to any of the three tested allergens at the age of 4 or as a positive skin prick test to any of the six tested allergens at the age of 6. McCarthy Scales of Child Abilities and California Preschool Social Competence Scale were the psychometric instruments used. Twelve percent of children at the age of 4 and 17% at the age of 6 were atopic. Neurobehavioral scores were negatively associated with 6-year-old atopy after adjustment for socio-demographic and allergic factors, A relative risk of 3.06 (95% CI: 1.30-7.24) was associated with the lowest tertile (scorings eczema at the age of 6, but not at the age of 4, were associated with neurodevelopment at the age of 4. Neuropsychologic functioning and later atopy are negatively associated in preschool age children.

    Highlights: • Cervical lymph node hyperplasia is a benign processes. • Lymph node hyperplasia found in treated children and adolescents with lymphoma. • We define imaging manifestations of cervical lymph node hyperplasia in PET/CT. • Awareness of lymph node hyperplasia avoid invasive procedures and over-treatment. - Abstract: Purpose: To define imaging manifestations and clinical prognosis of cervical lymph node hyperplasia using [ 18 F]-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) scanning after treatment of children and adolescents with malignant lymphoma. Methods: Children and adolescent patients with malignant lymphoma who had high FDG uptake in their cervical lymph nodes via PET/CT after treatment, which was not due to tumor recurrence or residue, were retrospectively analyzed. Results: Twenty-seven patients with a median age of 12 years were included; 11 had Hodgkin's disease and 16 had non-Hodgkin's lymphoma. The time from PET/CT scan to completion of therapy was 1–36 months, 85.2% (23/27) of which took place within 12 months. Three patients had confirmed lymph node follicular hyperplasia by biopsy, while all 27 patients achieved disease-free survival during the follow-up period. The maximum standardized uptake values (SUV max ) of cervical lymph nodes were 2.2–16.2 and the maximum short axis ranged from 0.3 to 1.2 cm. Cervical lymph node hyperplasia was noted in neck levels I–V, and neck level II bilaterally had the highest incidence (100%). Bilateral cervical lymph node hyperplasia was symmetrical in terms of both the SUV max and affected locations. Thymic hyperplasia and nasopharyngeal lymphoid hyperplasia were both observed in 24 patients (88.9%). There was no relationship in terms of the SUV max between cervical lymph nodes and thymic tissue, cervical nodes or nasopharyngeal lymphoid tissue. Conclusion: Cervical lymph node hyperplasia with high FDG uptake on PET/CT scans found after treating

    Full Text Available Benign prostatic hyperplasia (BPH has been described as the uncontrolled prostate gland growth which leads to difficulty in urination. One of the treatment of BPH is saw palmetto lipid extracts which has been shown to inhibit prostate 5 α-reductase and some of its components (lauric acid, myristic acid and oleic acid also inhibit the enzyme. Coffee was also rich in fatty acids namely linoleic acid, oleic acid and palmitic acid. The aim of this research is to investigate whether coffee is effective in preventing testosterone-induced prostatic hyperplasia in rats using testosterone propionate and estradiol valerate. After and before the induction, the rats were tested for prostate specific antigen (PSA . The condition of the prostate gland of the test animals were correlated with the results of the said test and in the histopathologic results. After 14 days of experimentation, animals in the test group significantly decreased their PSA levels as compared to the BPH group. The histomorphology showed that Coffea arabica bean oil inhibited testosterone propionate while estradiol valerate induced prostatic hyperplasia. These findings indicate that Coffee arabica bean oil effectively inhibited the development of BPH. With the proven safety of coffee oil, these findings strongly support the feasibility of using Coffea arabica bean oil therapeutically in treating BPH.

  15. 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.

    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

    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 most cases, the histopathologic and cytologic distinction between Graves' disease and papillary thyroid carcinoma is relatively easy, but on occasion Graves' disease may simulate a thyroid papillary carcinoma. For example, papillary fronds with fibrovascular cores may be present in both Graves' disease and papillary carcinoma. p27kip1 (p27) is a cyclin-dependent kinase inhibitory protein that has been shown to be an independent prognostic factor in a variety of human tumors. Our previous studies of p27 expression in hyperplastic and neoplastic endocrine lesions showed that the level of p27 was quite different in these two conditions. To determine if this distinction could also be made between Graves' disease and papillary carcinoma, we analyzed expression of p27 and other cell cycle proteins in a series of cases of Graves' disease with papillary hyperplasia and a series of papillary thyroid carcinomas. Formalin-fixed paraffin-embedded tissues from 61 randomly selected patients with thyroid disease, including 29 cases of Graves' disease with papillary architectural features and 32 cases of papillary carcinoma, were analyzed for expression of p27, Ki-67, and DNA topoisomerase II alpha (topo II alpha) by immunostaining. The distribution of immunoreactivity was analyzed by quantifying the percentage of positive nuclei that was expressed as the labeling index (LI) plus or minus the standard error of the mean. The papillary hyperplasia of Graves' disease had a p27 LI of 68.2 +/- 3.1 (range, 24 to 88), whereas papillary carcinomas had a LI of 25.6 +/- 2.5 (range, 12 to 70) (P hyperplasia in Graves' disease and papillary carcinoma. These results indicate that p27 protein expression is significantly higher in papillary hyperplasia of Graves' disease compared to papillary carcinoma, which may be diagnostically useful in difficult cases.

    Full Text Available The articles presents a view of the pharmacological and nutritive therapy of the most frequent diseases of males, which are benign prostatic hyperplasia and chronic prostatitis. A modern man is in constant deficiency of various biologically active substances, with the lack of them in food and without generating of sufficient quantity of coenzymes and enzymes. In the author,s opinion, complex drugs that contain highquality biological extracts may provide the substances required for prevention and slowing down the progress of benign prostatic hyperplasia and chronic prostatitis to the male organism. Study of biological activity of food supplement Andro-PRO (Russia that contain the elements required for normalization of the functional state of the prostate was performed. Application of the drug favors positive dynamics of clinical symptoms of the studied nosological entities and has restorative effect on the function of the glandular tissue of the prostate. Analysis of modern references, primary results of clinical studies show the necessity of pharmacological and nutritive support of patients with asymptomatic progress of benign prostatic hyperplasia and chronic prostatitis with the drug. Application of drug studied is efficient and safe, which is confirmed with improvement of indicators and life quality assessment, positive clinical dynamics, and absence of side effects.

    The Polycomb group protein enhancer of zeste homolog 2 (EZH2), which has roles during development of numerous tissues, is a critical regulator of cell type identity. Overexpression of EZH2 has been detected in invasive breast carcinoma tissue samples and is observed in human breast tissue samples of morphologically normal lobules up to 12 years before the development of breast cancer. The function of EZH2 during preneoplastic progression in the mammary gland is unknown. To investigate the role of EZH2 in the mammary gland, we targeted the expression of EZH2 to mammary epithelial cells using the mouse mammary tumor virus long terminal repeat. EZH2 overexpression resulted in aberrant terminal end bud architecture. By the age of 4 months, 100% of female mouse mammary tumor virus-EZH2 virgin mice developed intraductal epithelial hyperplasia resembling the human counterpart accompanied by premature differentiation of ductal epithelial cells and up-regulation of the luminal marker GATA-3. In addition, remodeling of the mammary gland after parturition was impaired and EZH2 overexpression caused delayed involution. Mechanistically, we found that EZH2 physically interacts with beta-catenin, inducing beta-catenin nuclear accumulation in mammary epithelial cells and activating Wnt/beta-catenin signaling. The biological significance of these data to human hyperplasias is demonstrated by EZH2 up-regulation and colocalization with beta-catenin in human intraductal epithelial hyperplasia, the earliest histologically identifiable precursor of breast carcinoma.

    CD8(+) T cells can be important effector cells in autoimmune inflammation, generally because they can damage target cells by cytotoxicity. This study shows that activated CD8(+) T cells induce thyroid epithelial cell hyperplasia and proliferation and fibrosis in IFN-γ(-/-) NOD.H-2h4 SCID mice in the absence of CD4(+) T cells. Because CD8(+) T cells induce proliferation rather than cytotoxicity of target cells, these results describe a novel function for CD8(+) T cells in autoimmune disease. In contrast to the ability of purified CD8(+) T cells to induce thyrocyte proliferation, CD4(+) T cells or CD8 T cell-depleted splenocytes induced only mild thyroid lesions in SCID recipients. T cells in both spleens and thyroids highly produce TNF-α. TNF-α promotes proliferation of thyrocytes in vitro, and anti-TNF-α inhibits development of thyroid epithelial cell hyperplasia and proliferation in SCID recipients of IFN-γ(-/-) splenocytes. This suggests that targeting CD8(+) T cells and/or TNF-α may be effective for treating epithelial cell hyperplasia and fibrosis.

    Fibrous hyperplasia is treated by surgical incision using a scalpel, together with removal of the source of chronic trauma. However, scalpel techniques do not provide the haemostasis that is necessary when dealing with highly vascular tissues. Diode laser surgery can be used in the management of oral tissues due to its high absorption by water and haemoglobin, and has provided good results in both periodontal surgery and oral lesions. The aim of the present study was to compare the effects of diode laser surgery to those of the conventional technique in patients with fibrous hyperplasia. A randomized clinical trial was performed in which surgical and postoperative evaluations were analyzed. On comparison of the laser-treated (study group) patients to those treated with a scalpel (control group), significant differences were observed in the duration of surgery and the use of analgesic medications. Over a 3-week period, clinical healing of the postoperative wound was significantly faster in the control group as compared to the study group. In conclusion, diode laser surgery proved to be more effective and less invasive when compared to scalpel surgery in the management of fibrous hyperplasia. However, wound healing proved to be faster when using scalpel surgery. Copyright © 2015 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Finasteride, a 5 alpha reductase inhibitor, is an established treatment for benign prostatic hyperplasia. The recommended dosage is 5 mg a day, however case reports have show effectiveness with lower doses. The objective of the current study was to determine in men with benign prostatic hyperplasia, previously treated for at least one year with finasteride 5 mg daily, if they will maintain subjective and objective improvements in urinary obstruction when treated with 2.5 mg of finasteride daily for one year. Methods In an open label, prospective study, 40 men with benign prostatic hyperplasia, previously treated for at least one year with 5 mg of finasteride, took 2.5 mg of finasteride daily for one year. Measurements included AUA symptom score, maximum flow rate, voided volume and PSA. Results There were no significant changes in maximum flow rate, voided volume, or AUA symptom score after one year of finasteride 2.5 mg daily therapy. PSA increased significantly, p Conclusions The daily dose of finasteride can be reduced to 2.5 mg daily without significant effect on subjective and objective measures of urinary obstruction. Although statistically significant increases in PSA are noted when reducing the daily finasteride dose from 5 mg to 2.5 mg, the clinical significance of a mean .6 ng/ml increase in PSA is questionable.

    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 Abstract Background Most research concerning congenital adrenal hyperplasia (CAH and related conditions caused by primary adrenal insufficiency, such as Addison's or Cushing's disease, has focused on medical aspects rather than on patients' quality of life. Therefore, our objective was to investigate the physical, social and societal functioning of children with CAH and their parents in a Dutch population. Methods The study is descriptive and cross-sectional. Self-designed questionnaires, based on questionnaires developed in the Netherlands for different patient groups, were sent to parents of children with CAH between 0 and 18 years old. Participants were recruited through the Dutch patient group for Adrenal Disease (NVACP and six hospitals in the Netherlands. Three different questionnaires were designed for parents: for children aged 0 - 4, aged 4 - 12 and aged 12 - 18. Additionally, a fourth questionnaire was sent to adolescents with CAH aged 12 - 18. Main outcome measures were experienced burden of the condition, self-management and participation in several areas, such as school and leisure time. Results A total of 106 parents returned the questionnaire, 12 regarding pre-school children (0-4 years, 63 regarding primary school children (4-12 years, and 32 regarding secondary school children (12-18 years, combined response rate 69.7%. Also, 24 adolescents returned the questionnaire. Children and adolescents with CAH appear to be capable of self-management at a young age. Experienced burden of the condition is low, although children experience several health related problems on a daily basis. Children participate well in school and leisure time. Few children carry a crisis card or emergency injection with them. Conclusions Overall, our research shows that, according to their parents, children with CAH experience few negative effects of the condition and that they participate well in several areas such as school and leisure time.

    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.

    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

    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.

    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.

    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.

    Doping presents a potential health risk for young athletes. Prevention programs are intended to prevent doping by educating athletes about banned substances. However, such programs have their limitations in practice. This led Germany to introduce the National Doping Prevention Plan (NDPP), in hopes of ameliorating the situation among young elite athletes. Two studies examined 1) the degree to which the NDPP led to improved prevention efforts in elite sport schools, and 2) the extent to which newly developed prevention activities of the national anti-doping agency (NADA) based on the NDPP have improved knowledge among young athletes within elite sports schools. The first objective was investigated in a longitudinal study (Study I: t0 = baseline, t1 = follow-up 4 years after NDPP introduction) with N = 22 teachers engaged in doping prevention in elite sports schools. The second objective was evaluated in a cross-sectional comparison study (Study II) in N = 213 elite sports school students (54.5 % male, 45.5 % female, age M = 16.7 ± 1.3 years (all students had received the improved NDDP measure in school; one student group had received additionally NADA anti-doping activities and a control group did not). Descriptive statistics were calculated, followed by McNemar tests, Wilcoxon tests and Analysis of Covariance (ANCOVA). Results indicate that 4 years after the introduction of the NDPP there have been limited structural changes with regard to the frequency, type, and scope of doping prevention in elite sport schools. On the other hand, in study II, elite sport school students who received further NADA anti-doping activities performed better on an anti-doping knowledge test than students who did not take part (F(1, 207) = 33.99, p doping-prevention in elite sport schools as part of the NDPP was only partially successful. The results of the evaluation indicate that the introduction of the NDPP has contributed more to a change in the

    In April 1993 a whole body counter intercomparison campaign, The 1993 Intercomparison/Intercalibration, started. The campaign has been organized by The Canadian National Reference Centre for In-Vivo Monitoring of Radiation Protection Bureau, Health Canada and The United States Department of Energy and it was based on measurements on a BOMAB type phantom simulating a 4 years old child. The phantom was filled with radioactive tissue substitute resin and an unknown quantity of radioactivity. Each facility was asked to determine the identity and amount of the radionuclide(s), knowing that the specific activity in the 10 BOMAB's sections was the same. Each facility was also asked to calculate the minimum detectable activity of all the radionuclides detected in the phantom. 35 Facilities from 20 different Countries took part in the initiative. The Institute for Radiation Protection of the Environment Department of ENEA (ENEA AMB IRP) represented Italy. Intercomparison results supplied by ENEA AMB IRP as radionuclides identification, activity data and associated precision, minimum detectable activity levels, can be considered satisfactory and comparable with results supplied by similar-facilities

    Emotional dysregulation in childhood has been associated with various forms of later psychopathology, although no studies have investigated the personality related adolescent outcomes associated with early emotional dysregulation. The present study uses a typological approach to examine how the child behavior checklist-dysregulation profile (CBCL-DP) predicts DSM-5 pathological personality traits (as measured with the personality inventory for the diagnostic and statistical manual of mental disorders 5 or PID-5 by Krueger et al. (Psychol Med 2012)) across a time span of 4 years in a sample of 243 children aged 8-14 years (57.2 % girls). The results showed that children assigned to the CBCL-DP class are at risk for elevated scores on a wide range of DSM-5 personality pathology features, including higher scores on hostility, risk taking, deceitfulness, callousness, grandiosity, irresponsibility, impulsivity and manipulativeness. These results are discussed in the context of identifying early manifestations of persistent regulation problems, because of their enduring impact on a child's personality development.

    The allocation of resources to a peer partner is a prosocial act that is of fundamental importance. Joint rhythmic movement, such as occurs during musical interaction, can induce positive social experiences, which may play a role in developing and enhancing young children's prosocial skills. Here, we investigated whether joint rhythmic movement, free of musical context, increases 4-year-olds' sharing and sense of fairness in a resource allocation task involving peers. We developed a precise procedure for administering joint synchronous experience, joint asynchronous experience, and a baseline control involving no treatment. Then we tested how participants allocated resources between self and peer. We found an increase in the generous allocation of resources to peers following both synchronous and asynchronous movement compared to no treatment. At a more theoretical level, this result is considered in relation to previous work testing other aspects of child prosociality, for example, peer cooperation, which can be distinguished from judgments of fairness in resource allocation tasks. We draw a conceptual distinction between two types of prosocial behavior: resource allocation (an other-directed individual behavior) and cooperation (a goal-directed collaborative endeavor). Our results highlight how rhythmic interactions, which are prominent in joint musical engagements and synchronized activity, influence prosocial behavior between preschool peers.

    Purpose: Evaluate the efficacy and toxicity of image guided brachytherapy using inverse planning simulated annealing (IPSA) high-dose-rate brachytherapy (HDRB) boost for locoregionally advanced cervical cancer. Methods and Materials: From December 2003 through September 2009, 111 patients with primary cervical cancer were treated definitively with IPSA-planned HDRB boost (28 Gy in 4 fractions) after external radiation at our institution. We performed a retrospective review of our experience using image guided brachytherapy. Of the patients, 70% had a tumor size >4 cm, 38% had regional nodal disease, and 15% had clinically evident distant metastasis, including nonregional nodal disease, at the time of diagnosis. Surgical staging involving pelvic lymph node dissection was performed in 15% of patients, and 93% received concurrent cisplatin-based chemotherapy. Toxicities are reported according to the Common Terminology Criteria for Adverse Events version 4.0 guidelines. Results: With a median follow-up time of 42 months (range, 3-84 months), no acute or late toxicities of grade 4 or higher were observed, and grade 3 toxicities (both acute and late) developed in 8 patients (1 constitutional, 1 hematologic, 2 genitourinary, 4 gastrointestinal). The 4-year Kaplan-Meier estimate of late grade 3 toxicity was 8%. Local recurrence developed in 5 patients (4 to 9 months after HDRB), regional recurrence in 3 (6, 16, and 72 months after HDRB), and locoregional recurrence in 1 (4 months after HDR boost). The 4-year estimates of local, locoregional, and distant control of disease were 94.0%, 91.9%, and 69.1%, respectively. The overall and disease-free survival rates at 4 years were 64.3% (95% confidence interval [CI] of 54%-73%) and 61.0% (95% CI, 51%-70%), respectively. Conclusions: Definitive radiation by use of inverse planned HDRB boost for locoregionally advanced cervical cancer is well tolerated and achieves excellent local control of disease. However, overall

    The outcomes of hygiene audits carried out two times per year were used to determine the correct execution of the procedures foreseen by the Hazard Analysis and Critical Control Points (HACCP) plan over 4 years (2013-2016) in a university canteen producing about 1200 meals a day. Critical analysis of hygiene audits. Hygiene audits were carried out on the basis of a checklist divided into seven main items and subitems that covered all the production areas of the canteen. For each audit subitem, total percentage of inadequacy was calculated as the total number of negative answers (N) divided by the total number of answers (n = 8) collected in the period 2013-2016. The results showed a discontinuous trend among years. In more detail, the highest percentage of inadequacy was seen for food maintaining temperatures, thus highlighting management issues mainly related to time taken for food preparation. A relatively high level of inadequacy was also recorded for staff clothing and hygiene. The critical analysis of data emerged from the audits was useful to obtain an overview of improvements and emerging criticalities. Copyright © 2018 The Royal Society for Public Health.

    Longitudinal, population-based studies can better assess the relationship of ecstasy use with depression. We examined whether change in ecstasy use was associated with change in depressive symptoms/probable depression over a 4-year period, among a large Australian sample. The Personality and Total Health project is a longitudinal general community study of Australians from Canberra and Queanbeyan. Data from the youngest cohort when aged 24-30 (N = 2, 128) and 4 years later (N = 1, 977) was included. The Goldberg depression scale and the Brief Patient Health Questionnaire measured depressive symptoms and probable depression, respectively. Multilevel growth models also considered demographics, psychosocial characteristics, and other drug use. Ecstasy use was not associated with long-term depressive symptoms or greater odds of depression in multivariate analyses. Users had more self-reported depressive symptoms when using ecstasy compared to not using. However, differences between people who had and had not ever used ecstasy largely accounted for this. Other factors were more important in the prediction of depression. It would be premature to conclude that ecstasy use is not related to the development of long-term depressive symptoms, given the relatively low level of ecstasy and other drug use in this community sample. Results showed that other factors need to be considered when investigating ecstasy use and depression.

    Full Text Available Traumatic ventricular septal defect (VSD resulting from blunt chest injury is a very rare event. The mechanisms of traumatic VSD have been of little concern to dateuntil now, but two dominant theories have been described. In one, the rupture occurs due to acute compression of the heart; in the other, it is due to myocardial infarction of the septum. The clinical symptoms and timing of presentation are variable, so appropriate diagnosis can be difficult or delayed. Closure of traumatic VSD has been based on a combination of heart failure symptoms, hemodynamics, and defect size. Here, we present a case of a 4-year-old boy who presented with a traumatic VSD following a car accident. He showed normal cardiac structure at the time of injury, but after 8 days, his repeated echocardiography revealed a VSD. He was successfully treated by surgical closure of the VSD, and has been doing well up to the present. This report suggests that the clinician should pay great close attention to the patients injured by blunt chest trauma, keeping in mind the possibility of cardiac injury.

    The purpose of the current study was to examine the longitudinal reciprocal relationship between depression and drinking among male adults from the general population. This study used a panel dataset from the Korean Welfare Panel (from 2011 to 2014). The subjects were 2511 male adults aged between 20 and 65 years. Based on the Korean Version of the Alcohol Use Disorders Identification Test (AUDIT-K) scores, 2191 subjects were categorized as the control group (AUDIT-K AUDIT-K ≥ 12). An autoregressive cross-lagged modelling analysis was performed to investigate the mutual relationship between problem drinking and depression measured consecutively over time. The results indicated that alcohol drinking and depression were stable over time. In the control group, there was no significant causal relationship between problem drinking and depression while in the problem drinking group, drinking in the previous year significantly influenced depression in the following second, third and fourth years. This study compared normal versus problem drinkers and showed a 4-year mutual causal relationship between depression and drinking. No longitudinal interaction between drinking and depression occurred in normal drinkers, while drinking intensified depression over time in problem drinkers. This study found that problem drinking was a risk factor for development of depression. Therefore, more attention should be given to problem alcohol use in the general population and evaluation of past alcohol use history in patients with depressive disorders.

Mice were irradiated 30 minutes 5days/week (12 weeks, and group C-D treated five days/week (12 weeks. Skin samples were taken in the mid and end of the experiment. The result of this study revealed that, epidermal thickness in group A was 7.155µm. At the mid-period of the experiment, severe epidermal hyperplasia was observed in group B with epidermal thickness 118.712µm, while in group C and D mild to moderate epidermal hyperplasia were noted with decreasing epidermal thickness to 64.154 and 90.042µm respectively. At the end of the experiment in Group B epidermal thickness reached to 281.35µm with seborrheic keratosis development, whereas in group C and D totally inhibited the development of seborrheic keratosis and epidermal thickness decreased again into 42.347 and 55.915µm. In conclusion, chronic UVB radiation-led to epidermal hyperplasia and seborrheic keratosis, sunscreen prevented the development of seborrheic keratosis and decreased the UVB-induced epidermal hyperplasia.

    Full Text Available Based on long-term follow-up to perform comparative analysis of long-term results of surgical treatment of myasthenia. A retrospective analysis of long-term results of surgical treatment of 146 patients with myasthenia has been carried out. We used the modified Keynes classification to estimate the severity of myasthenia and to summarize the data relating to therapy volume and treatment results. In dependence on the type of thymus lesion patients were divided into two groups. Thymus hyperplasia was verified at — 106 (72.6 % patients, tumor lesion of the thymus gland (thymoma — at 40 (27.4 % ones. The results were estimated in the following periods after thymectomy: 1—2 years, 3—4 years, 5—6 years, 7 — 9 years, 10—14 years, and over 15 years. Short- and longterm results of surgical treatment of myasthenia for the patients without tumor lesions of the thymus gland were significantly better. Positive effects of surgical treatment of myasthenia in patients with hyperplasia are observed after 1 year of surgery (p = 0.0023, and the best results are observed after 5 — 6 year of the disease, then after 7 — 9 year one notes some deterioration of state (p = 0.026.

    Testing episodic foresight in children generally involves presenting them with a problem in one location (e.g., Room A) and, after a spending a delay in a different location, telling them they will be returning to Room A. Before they go, children are presented with a number of items, one of which will allow them to solve the problem in Room A. At around 3 to 4 years of age children display episodic foresight, selecting the item that will allow them to solve the problem. To date, however, no study has assessed whether 3- and 4-year-old children can plan beyond the very next event, selecting the correct item when there is a delay before returning to Room A. Here, we show that 3- and 4-year-old children can pass when a delay is imposed but that their performance is significantly worse than when they are planning for an immediate event. © 2017 Wiley Periodicals, Inc.

    Objective: To determine whether there is any correlation between parathyroid hyperplasia, as detected by high-resolution ultrasound, and clinical and laboratory variables in patients with hyperparathyroidism secondary to stage-5 chronic kidney disease (CKD) on hemodialysis. Design: Descriptive. Location: RTS Ltda. Renal Unit in Caldas, Santa Sofia Hospital and Children's Hospital. Patients: All patients, 18 years of age, with stage- 5 CKD who were on dialysis therapy (hemodialysis or peritoneal dialysis), and with PTH levels greater than 400 pg/ml. Methods: After giving their written consent to participate in the study, all patients underwent high-resolution thyroid and parathyroid ultrasound (Phillips Team Enviisor CHD -12 MHz transducer) performed by a medical specialist in radiology. Variables such as etiology, duration of the CKD, time on dialysis therapy, type of dialysis, presence of symptoms related to hyperparathyroidism (bone pain, fractures, pruritus), and laboratory variables like an intact PTH, calcium, phosphorus, calcium x phosphorus, and alkaline phosphatase were analyzed in order to determine if there was a significant correlation between the variables and the detection of parathyroid hyperplasia documented by high resolution ultrasound. Results: Of 403 patients evaluated, 92 met the inclusion criteria, 86 were scanned and 6 were excluded. In these patients, the most common cause of CKD was hypertensive nephrosclerosis. Thirty-seven patients were on peritoneal dialysis and 49 on hemodialysis, with an average time on dialysis of 61.4 +- 36.6 months. The average levels of PTH in pg/mL were 829,465 +- 473,631. The most prevalent clinical symptom was bone pain, found in 52.2% of patients. Ultrasound showed enlarged parathyroid glands in 30 patients (34.88%), with single-gland hyperplasia in 23 (26.74%), two-gland hyperplasia in 4 (4.65%) and three-gland hyperplasia in 3 (3.48%).

    2011-10-15

    This is a presentation of NKS (Nordic Nuclear Safety Research), its work and achievements in the years 1994 - 2008, during which the author served as Nordic secretary and (later) as coordinator. NKS and the Nordic perspective are briefly introduced together with the NKS support structure, organization and administration: Owners, Board, Nordic secretary, Bureau and Secretariat. The author then embarks on a journey through the modern history of NKS work. The last two of the six fixed 4-year programs are described as regards planning, contents, project work, administration, dissemination of results, evaluations and conclusions. The trip continues to the land of R and B and the present (2011) structure of two general frameworks, namely, NKS-R: reactor safety, and NKS-B: emergency preparedness; each consisting of a set of flexible activities; hence, R and B. The reasoning behind this makeover is touched upon together with the new organization and simpler administration that developed. Major activities and the produced results are introduced and the evaluations summarized. The author's own conclusions and recommendations are followed by a short and subjective list of references. In a number of appendices some important background material has been compiled: bullet point versions of minutes of Owners Group and Board meetings; economic contributions and budgets; the NKS policy document; an overview of all NKS programs and evaluations; lists of R and B activities and funding; the author's personal remarks; a list of some NKS documents (other than technical reports and minutes); and a list of acronyms used in this report.

    Full Text Available Abstract Background The spreading of whole slide imaging or digital slide systems in pathology as an innovative technique seems to be unstoppable. Successful introduction of digital slides in education has played a crucial role to reach this level of acceptance. Practically speaking there is no university institute where digital materials are not built into pathology education. At the 1st. Department of Pathology and Experimental Cancer Research, Semmelweis University optical microscopes have been replaced and for four years only digital slides have been used in education. The aim of this paper is to summarize our experiences gathered with the installation of a fully digitized histology lab for graduate education. Methods We have installed a digital histology lab with 40 PCs, two slide servers - one for internal use and one with external internet access. We have digitized hundreds of slides and after 4 years we use a set of 126 slides during the pathology course. A Student satisfaction questionnaire and a Tutor satisfaction questionnaire have been designed, both to be completed voluntarily to have feed back from the users. The page load statistics of the external slide server were evaluated. Results The digital histology lab served ~900 students and ~1600 hours of histology practice. The questionnaires revealed high satisfaction with digital slides. The results also emphasize the importance of the tutors' attitude towards digital microscopy as a factor influencing the students' satisfaction. The constantly growing number of page downloads from the external server confirms this satisfaction and the acceptance of digital slides. Conclusions We are confident, and have showed as well, that digital slides have got numerous advantages over optical slides and are more suitable in education.

  9. Adenoid basal hyperplasia of the uterine cervix: a lesion of reserve cell type, distinct from adenoid basal carcinoma.

    Adenoid basal hyperplasia is an underrecognized cervical lesion, resembling adenoid basal carcinoma, except the absence of deep invasion into the stroma. We report a series of 10 cases, all extending less than 1 mm from the basement membrane. Our results support the hypothesis that adenoid basal hyperplasia arises from reserve cells of the cervix. Lesions were found close to the squamocolumnar junction, in continuity with the nearby subcolumnar reserve cells. They shared the same morphology and immunoprofile using a panel of 4 antibodies (keratin 5/6, keratin 14, keratin 7 and p63) designed to differentiate reserve cells from mature squamous cells and endocervical columnar cells. We detected no human papillomavirus infection by in situ hybridization targeting high-risk human papillomavirus, which was concordant with the absence of immunohistochemical p16 expression. We demonstrated human papillomavirus infection in 4 (80%) of 5 adenoid basal carcinoma, which is in the same range as previous studies (88%). Thus, adenoid basal hyperplasia should be distinguished from adenoid basal carcinoma because they imply different risk of human papillomavirus infection and of subsequent association with high-grade invasive carcinoma. In our series, the most reliable morphological parameters to differentiate adenoid basal hyperplasia from adenoid basal carcinoma were the depth of the lesion and the size of the lesion nests. Furthermore, squamous differentiation was rare in adenoid basal hyperplasia and constant in adenoid basal carcinoma. Finally, any mitotic activity and/or an increase of Ki67 labeling index should raise the hypothesis of adenoid basal carcinoma. Copyright © 2012 Elsevier Inc. All rights reserved.

    2010-10-01

    We assess the outcome in 46,XX men with congenital adrenal hyperplasia who were born with Prader 4 or 5 genitalia and assigned male gender at birth. After receiving institutional review board approval and subject consent we reviewed the medical records of 12 men 35 to 69 years old with 46,XX congenital adrenal hyperplasia, of whom 6 completed social and gender issue questionnaires. All subjects were assigned male gender at birth, were diagnosed with virilizing congenital adrenal hyperplasia at age greater than 3 years and indicated a male gender identity with sexual orientation to females. Ten of the 12 subjects had always lived as male and 2 who were reassigned to female gender in childhood subsequently self-reassigned as male. Nine of the 12 men had long-term female partners, including 7 married 12 years or more. The 3 subjects without a long-term female partner included 1 priest, 1 who was reassigned female gender, married, divorced and self-reassigned as male, and 1 with a girlfriend and sexual activity. All except the priest and the subject who was previously married when female indicated a strong libido and frequent orgasmic sexual activity. Responses to self-esteem, masculinity, body image, social adjustment and symptom questionnaires suggested adjustments related to the extent of familial and social support. Outcome data on severely masculinized 46,XX patients with congenital adrenal hyperplasia who were assigned male gender at birth indicate male gender identity in adulthood with satisfactory male sexual function in those retaining male genitalia. In men who completed questionnaires results were poorer in those lacking familial/social support. Male gender of rearing may be a viable option for parents whose children are born with congenital adrenal hyperplasia, a 46,XX karyotype and male genitalia, although positive parental and other support, and counseling are needed for adjustment.

    2017-08-01

    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 Objective: To gauge the gross and fine motor development of early treated phenylketonuria (ETPKU in children in the age range of 1–4 years. Materials & Methods: A cross-sectional analytic study was conducted in PKU clinics (reference clinics for PKU follow-up, Tehran, Iran. Seventy children with ETPKU were selected as the case group for the study. ETPKU children were those with early and continuous treatment with a phenylalaninerestricted diet (the mean of blood phenylalanine level during the recent 6 months was 2–6 mg/dL or 120–360 mmol/L. Also, 100 healthy and normal children matched with the ETPKU group for age were randomly selected from 4 kindergartens in four parts of Tehran as a control group. The measurements consisted of a demographic questionnaire, Peabody Developmental Motor Scale-2 (PDMS-2, and pediatrician assessment. Motor quotients were determined by PDMS-2 and then compared in both groups by two independent samples t-test. Results: The mean ages in case and control group were 28.5 (±11.6 and 29.7 (±11.3 months, respectively. Comparison of the mean fine, gross, and total developmental motor quotients (DMQs showed statistically significant differences between the two groups (P<0.05. The fine and total DMQs of ETPKU children were also correlated with age. In addition, there was a negative correlation between the phenylalanine level and fine (P<0.001 and total (P=0.001 DMQs. Conclusion: It seems that ETPKU Iranian children, regardless of following a phenylalanine-restricted diet or not, have lower motor development. It is recommended to plan programs for early detection and intervention of developmental delays in these children.

    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.

    2017-08-01

    To determine lipid profiles in early childhood and evaluate their association with weight status at 4 years of age. Additionally, we evaluated whether the risk of overweight or having an altered lipid profile was associated with parental weight status. Five hundred eighty two mothers and their 4-year-old children from 2 Spanish population-based cohorts were studied. Weight status in children at 4 years of age was classified as overweight or obese using the International Obesity Task Force criteria. Plasma total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were determined in children and lipid ratios were calculated. A proatherogenic lipid profile was defined as having the 3 lipid ratios in the third tertile. A total of 12.9% of children were overweight and 6.4% were obese. Weight status at 4 years of age was related to maternal prepregnancy body mass index, paternal body mass index, gestational diabetes, and birth weight, but not with other sociodemographic characteristics of the mother. We found no association with gestational age, sex of the child, or breastfeeding. The risk of overweight/obesity was increased 4.17-fold if mothers were overweight/obese (95% CI 1.76-9.88) and 5.1-fold (95% CI 2.50-10.40) if both parents were overweight/obese. There were 133 children (22.8%) with a proatherogenic lipid profile. The risk of a proatherogenic lipid profile was increased 2.44-fold (95% CI 1.54-3.86) if they were overweight/obese at 4 years of age and 2-fold if the father was overweight/obese (95% CI 1.22-3.35). Four-year-old overweight/obese children have higher lipid risk profiles. Offspring of overweight/obese parents have an increased risk for obesity and a proatherogenic lipid profile.

    2008-01-01

    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

    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.)

    CT-assessed density changes in lung tissues were measured in 22 disease-free breast cancer patients 4 years after completion of radiation therapy. All patients had previously undergone similar CT-examinations before treatment, 3 months, and 9 months after radiotherapy. In patients with visible areas of increased lung density at earlier CT-examinations a decrease of focal findings was observed at 4 years. In patients without focal findings, an increase in density relative to that before therapy was observed. The difference between the mean lung density values among those with visible radiological findings and those without was statistically significant both at 3 and 9 months after therapy. However, this difference did not persist at 4 years. These results may indicate a 2-phase development of radiation-induced lung damages - an acute phase and a late phase; the late phase emerging slowly, and in this study detectable 4 years after completion of radiation therapy.

    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.

    Full Text Available Congenital adrenal hyperplasia (CAH patients with testicular adrenal rest tumors (TARTs with testicular enlargement present a serious diagnostic challenge. According to the data TARTs are usually benign. They are rare, resulting in paucity in the medical literature regarding their pathological features. We report a case of bilateral synchronous mass-forming TARTs with marked cytological and nuclear atypia misinterpreted as malignant testicular tumors in a 40-years-old man with CAH and CT and MRI data for pheochromocytoma of the right adrenal gland and paraaortal and paracaval lymphadenomegaly. He was previously diagnosed with adrenal cortical carcinoma of the left adrenal gland.

    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 Chronic inflammatory skin diseases such as psoriasis have a significant impact on society. Currently, the major topical treatments have many side effects, making their continued use in patients difficult. Microalgae have emerged as a source of bio-active molecules such as glycolipids with potent anti-inflammatory properties. We aimed to investigate the effects of a glycolipid (MGMG-A and a glycolipid fraction (MGDG obtained from the microalga Isochrysis galbana on a TPA-induced epidermal hyperplasia murine model. In a first set of experiments, we examined the preventive effects of MGMG-A and MGDG dissolved in acetone on TPA-induced hyperplasia model in mice. In a second step, we performed an in vivo permeability study by using rhodamine-containing cream, ointment, or gel to determinate the formulation that preserves the skin architecture and reaches deeper. The selected formulation was assayed to ensure the stability and enhanced permeation properties of the samples in an ex vivo experiment. Finally, MGDG-containing cream was assessed in the hyperplasia murine model. The results showed that pre-treatment with acetone-dissolved glycolipids reduced skin edema, epidermal thickness, and pro-inflammatory cytokine production (TNF-α, IL-1β, IL-6, IL-17 in epidermal tissue. The in vivo and ex vivo permeation studies showed that the cream formulation had the best permeability profile. In the same way, MGDG-cream formulation showed better permeation than acetone-dissolved preparation. MGDG-cream application attenuated TPA-induced skin edema, improved histopathological features, and showed a reduction of the inflammatory cell infiltrate. In addition, this formulation inhibited epidermal expression of COX-2 in a similar way to dexamethasone. Our results suggest that an MGDG-containing cream could be an emerging therapeutic strategy for the treatment of inflammatory skin pathologies such as psoriasis.

    The objectives of this study were to examine changes in body weight, body mass index (BMI), body composition, and shape in a group of male and female students over the 4-year college period. Anthropometric assessments including height and weight (via standard techniques), body composition (via bioelectrical impedance analysis), and body shape (via 3-dimensional body scanning) were conducted at the beginning of the freshman year and end of the senior year in 131 college students. Four-year changes included significant (p obese increased from 18% to 31%. The number of females and males with ≥30% and 20% body fat, respectively, increased from n = 14 to n = 26 (with n = 4 exhibiting normal weight obesity) over the 4-year period. The waist circumference changes were significantly (p obesity and normal weight obesity among this college population suggests the need for additional health promotion strategies on college campuses.

    Trichomonas vaginalis causes the most prevalent sexually transmitted infection worldwide. Trichomonads have been detected in prostatic tissues from prostatitis, benign prostatic hyperplasia (BPH), and prostate cancer. Chronic prostatic inflammation is known as a risk factor for prostate enlargement, benign prostatic hyperplasia symptoms, and acute urinary retention. Our aim was to investigate whether T. vaginalis could induce inflammatory responses in cells of a benign prostatic hyperplasia epithelial cell line (BPH-1). When BPH-1 cells were infected with T. vaginalis, the protein and mRNA of inflammatory cytokines, such as CXCL8, CCL2, IL-1β, and IL-6, were increased. The activities of TLR4, ROS, MAPK, JAK2/STAT3, and NF-κB were also increased, whereas inhibitors of ROS, MAPK, PI3K, NF-κB, and anti-TLR4 antibody decreased the production of the 4 cytokines although the extent of inhibition differed. However, a JAK2 inhibitor inhibited only IL-6 production. Culture supernatants of the BPH-1 cells that had been incubated with live T. vaginalis (trichomonad-conditioned medium, TCM) contained the 4 cytokines and induced the migration of human monocytes (THP-1 cells) and mast cells (HMC-1 cells). TCM conditioned by BPH-1 cells pretreated with NF-κB inhibitor showed decreased levels of cytokines and induced less migration. Therefore, it is suggested that these cytokines are involved in migration of inflammatory cells. These results suggest that T. vaginalis infection of BPH patients may cause inflammation, which may induce lower urinary tract symptoms (LUTS).

    We retrospectively evaluated urologist adherence to the AUA guidelines on the management of new patients with benign prostatic hyperplasia related lower urinary tract symptoms in a large university urology group. All first time benign prostatic hyperplasia/lower urinary tract symptom visits to the urology clinic at the Northwestern Medical Faculty Foundation between January 1, 2008 and December 31, 2012 were evaluated using an institutionally managed electronic medical record data repository. Clinical documentation and orders from each encounter were assessed to determine the rate of performance of guideline measures. Approximately 1% of all results were manually reviewed in a validation process designed to determine the reliability of the electronic medical record based system. A total of 3,494 eligible encounters were evaluated in the final analysis. Provider adherence rates with the 9 measures recommended in the guidelines varied by measure from 53.0% to 92.8%. The rate of performance of 5 not routinely recommended measures was 10.2% or less. Post-void residual and urinary flow measurement were optional measures, and were performed on 68.1% and 4.6% of new encounters respectively. Manual validation revealed the electronic medical record data extraction was concordant with manual review in 96.7% of cases (95% CI 94.8-98.5). Using electronic medical record based data extraction techniques, we reliably document a baseline adherence rate with AUA guidelines on the management of benign prostatic hyperplasia. Establishing this benchmark will be important for future investigation into patient outcomes related to guideline adherence and into methods for improving provider adherence.

Improved results can be obtained by drug vectorization to the hyperplastic tissue. The main objective of this work was the preparation and characterization of poly(lactic-co-glycolic acid (PLGA nanoparticle and clay nanosystems containing babassu oil (BBS. BBS was extracted from the kernels of babassu tree nuts and characterized by gas chromatography-mass spectrometry as well as 1H and 13C nuclear magnetic resonance. BBS-clay nanosystems were obtained by adding polyvinylpyrrolidone, Viscogel B8®, and BBS at a 2:1:1 mass ratio and characterized by X-ray diffraction, thermogravimetric analysis, infrared spectroscopy, and laser diffraction. The PLGA-BBS nanoparticles were prepared by the precipitation-solvent evaporation method. Mean diameter, polydispersity, zeta potential, and scanning electron microscopic images of the nanosystems were analyzed. Thermogravimetric analysis showed successful formation of the nanocomposite. PLGA nanoparticles containing BBS were obtained, with a suitable size that was confirmed by scanning electron microscopy. Both nanostructured systems showed active incorporation yields exceeding 90%. The two systems obtained represent a new and potentially efficient therapy for benign prostatic hyperplasia.

    Benign prostatic hyperplasia (BPH) is a disease of senile age, usually occurring> 60 years of age. BPH is a disease that involves cell proliferation of the prostate. Pathological hyperplasia affects the elements of the glandular and connective tissue of the prostate. This study is designed to scrutinize the efficacy and tolerability of herbal drug Anti BPH capsule for the management of benign prostate hyperplasia (BPH), in this study we select the 100 patients in which 50 received the Anti BPH capsule and 50 received the Terazosin HCl. We use the American Urological Association BPH Symptom Score Index Questionnaire to measure the quality of life of the patients. We compare the before treatment and after treatment results for each symptom. We record the following symptoms, incomplete emptying of bladder, Frequency, Intermittency, Urgency, Weak stream, Straining, Nocturia and weight of prostate gland by USG. We compare the both drug by using paired sample t-test. The level of significance of incomplete emptying of bladder before treatment and after treatment is 0.013 in test group and 0.032 in control group. Similarly the level of significance of Frequency before treatment and after treatment in test groups in, intermittency, Urgency, Weak stream, staining, Nocturia and mean weight of prostate gland are 0.007, 0.015, 0.044, 0.012, 0.017, 0.004 and 0.020; where as in control group afford as 0.031, 0.044, 0.044, 0.032, 0.024, 0.009 and 0.035 respectively. The herbal drug Anti BPH capsule is more effective in the treatment of BPH than Allopathic medicine Terazosin HCl.

    Full Text Available BackgroundBenign Prostatic Hyperplasia is a widely prevalent conditionaffecting elderly men throughout the world. With increasinglife expectancy, there has been a rise in the percentage ofelderly men and so for this disease across the globe. There islack of information about health seeking behaviour of patientswith Benign Prostatic Hyperplasia. Therefore the study wasdesigned with the objectives of assessing health-seekingbehaviour and the effect of literacy on it among adult andolder subjects suffering from Benign Prostatic Hyperplasiaattending a tertiary care hospital.MethodA series of 81 patients suffering from Benign ProstaticHyperplasia above the age of 50 years, attending surgical OutPatient Department of a tertiary care hospital in Delhi, wereassessed for their health seeking behaviour using a pre-testedand a modified questionnaire designed for assessing healthseeking behaviour.ResultsPositive health seeking behaviour of patients was observed in44%, who reported to a doctor within a month of noticingtheir problem. A greater proportion of the literates was awareabout the symptoms suggestive of enlarged prostate andconsulted a qualified health care practitioner as their firstaction. More literates approached the higher level of healthcare facility on being referred and had maximum faith inallopathic system of medicine. Also, lesser number of literateshad performed pooja (Hindi word for worship or othertraditional rituals for relief of their problems.ConclusionWe concluded that majority of subjects suffering fromBenign Prostatic Hypertrophy were not aware of theirdisease and their health-seeking behaviour was poor andcould be related to literacy. Our data highlights the needfor public awareness program targeting the younger malepopulation so that early detection and treatment can beoffered.

    Full Text Available Somatic GNAS point mutations, commonly known as gsp mutations, are involved in the pathogenesis of McCune Albright syndrome and have also been described in autonomous hormone-producing tumors, such as somatotropinoma, corticotrophoma, thyroid cancer, ovarian and testicular Leydig cell tumors and primary macronodular adrenocortical hyperplasia (PMAH. [1-3]The involvement of gsp mutations in adrenal tumors was first described by Lyons et al. in 1990. Since then, several studies have detected the presence of gsp mutations in adrenal tumors, but none of them could explain its presence along or the mechanism that leads to tumor formation and hormone hypersecretion. As a result, the molecular pathogenesis of the majority of sporadic adrenocortical tumors remains unclear. [3] PMAH has also been reported with gsp somatic mutations in a few cases. Fragoso et al. in 2003 identified two distinct gsp somatic mutations affecting arginine residues on codon 201 of GNAS in a few patients with PMAH who lacked any features or manifestations of McCune Albright syndrome. Followed by this discovery, other studies have continued looking for gsp mutations based on strong prior evidence demonstrating that increased cAMP signaling is sufficient for cell proliferation and cortisol production. [2, 4] With consideration for the previously reported findings, we conjecture that although somatic activating mutations in GNAS are a rare molecular event, these mutations could probably be sufficient to induce the development of macronodule hyperplasia and variable cortisol secretion.In this manuscript, we revised the presence of gsp mutations associated with adrenal cortical tumors and hyperplasia.

    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.

    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.

    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

    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.

Analyses of falling water tables after rain indicated slight clogging, but this effect is less important than the general lack of knowledge about soil permeability for normal design situations. The results indicate that the stormwater infiltration in central urban areas with compressed soils...... an initial soil survey. Although the two trenches are placed close to each other they function rather differently, corresponding to effective soil permeabilities of 2.10(-6) m/s in one trench and a factor 10 smaller in the other.

    Full Text Available Hypomelanosis of ito (HI is a multisystemic disorder characterized by cutaneous, neurologic disorder, and musculoskeletal disorder. However, there may be isolated cutaneous manifestation, resulting in diagnostic overlap with other hypopigmentary lesions such as nevus depigmentosus and hypopigmentation along the lines of Blaschko. Therefore, there is the need for generally acceptable diagnostic criteria avoiding these ambiguities. Hence, the case of a 4-year-old female child with isolated hypopigmentations characterized as whorls on the torso and as linear distribution along the lines of Blaschko is reported.

    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

    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.

    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.

    Medical therapy is widely used for managing benign prostatic hyperplasia (BPH) and has made an impact on the profile of patients who ultimately undergo surgery. This changing profile may impact outcomes of surgery and associated complications. To assess the impact of medical management, we evaluated the profile of patients who had surgery for BPH at our institution. A retrospective chart-review was performed of patient demographics, indications for surgery, preoperative comorbid conditions and postoperative course in patients who underwent surgery for BPH over a 5-year period. The data were analysed for demographic trends in comparison with historical cohorts. A total of 327 patients underwent surgery for BPH between 2008 and 2012. Their mean age was 66.4 years, the mean prostate gland weight was 59.2 g and the mean duration of symptoms was 35.3 months; 34% had a prostate gland weight of >60 g; 1 59 (48.6%) patients had an absolute indication for surgery; 139 (42.5%) of these were catheterized and 6.1% of patients presented with azotaemia or upper tract changes without urinary retention. In comparison with historical cohorts, more patients are undergoing surgery for absolute indications including retention of urine and hydroureteronephrosis. However, the patients are younger, they have fewer comorbid conditions and have a similar rate of complications after the procedure.

    This paper deals with application of fuzzy intelligent systems in diagnosing severity level and recommending appropriate therapies for patients having Benign Prostatic Hyperplasia. Such an intelligent system can have remarkable impacts on correct diagnosis of the disease and reducing risk of mortality. This system captures various factors from the patients using two modules. The first module determines severity level of the Benign Prostatic Hyperplasia and the second module, which is a decision making unit, obtains output of the first module accompanied by some external knowledge and makes an appropriate treatment decision based on its ontology model and a fuzzy type-1 system. In order to validate efficiency and accuracy of the developed system, a case study is conducted by 44 participants. Then the results are compared with the recommendations of a panel of experts on the experimental data. Then precision and accuracy of the results were investigated based on a statistical analysis.

    Full Text Available OBJECTIVE: To perform a cost-effectiveness analysis of medical treatment of benign prostatic hyperplasia (BPH under Brazilian public health system perspective (Unified Health System - "Sistema Único de Saúde (SUS". MATERIAL AND METHODS: A revision of the literature of the medical treatment of BPH using alpha-blockers, 5-alpha-reductase inhibitors and combinations was carried out. A panel of specialists defined the use of public health resources during episodes of acute urinary retention (AUR, the treatment and the evolution of these patients in public hospitals. A model of economic analysis(Markov predicted the number of episodes of AUR and surgeries (open prostatectomy and transurethral resection of the prostate related to BPH according to stages of evolution of the disease. Brazilian currency was converted to American dollars according to the theory of Purchasing Power Parity (PPP 2010: US$ 1 = R$ 1.70. RESULTS: The use of finasteride reduced 59.6% of AUR episodes and 57.9% the need of surgery compared to placebo, in a period of six years and taking into account a treatment discontinuity rate of 34%. The mean cost of treatment was R$ 764.11 (US$449.78 and R$ 579.57 (US$ 340.92 per patient in the finasteride and placebo groups, respectively. The incremental cost-effectiveness ratio (ICERs was R$ 4.130 (US$ 2.429 per episode of AUR avoided and R$ 2.735 (US$ 1.609 per episode of surgery avoided. The comparison of finasteride + doxazosine to placebo showed a reduction of 75.7% of AUR episodes and 66.8% of surgeries in a 4 year time horizon, with a ICERs of R$ 21.191 (US$ 12.918 per AUR episodes avoided and R$ 11.980 (US$ 7.047 per surgery avoided. In the sensitivity analysis the adhesion rate to treatment and the cost of finasteride were the main variables that influenced the results. CONCLUSIONS: These findings suggest that the treatment of BPH with finasteride is cost-effective compared to placebo in the Brazilian public health system

    Benign prostatic hyperplasia (BPH) is a common disease in human that gradual overgrowth of the prostate gland leads to impinge on the urethra with impairment in urinary function. Numerous plants improve uncontrolled growth of the prostate gland and improve urinary tract symptoms associated with BPH. In this study, 25 healthy adult male Wistar rats were divided randomly in five groups: G1 (Control group) received ordinary feed without any treatment, G2 received 10 mg kg(-1) testosterone subcutaneously, G3 received 50 mg kg(-1) nettle root extract orally, G4 received 50 mg kg(-1) nettle root extract orally and 10 mg kg(-1) testosterone, G5 received 10 mg kg(-1) almond oil (Almond oil was used as testosterone solvent) subcutaneously. After six weeks, volume and weight of each lobe were measured and samples were taken. The 5 to 6 µm thickness sections were made using paraffin embedding method and stained by hematoxylin and eosin and periodic acid-Schiff. The results showed that prostate volume and ratio of prostate to body weight were increased significantly in the testosterone. Histological and histometrical results showed that dorsal and lateral type 1 and 2 lobes were not changed significantly but the ventral and anterior lobes have changed significantly. Over all, the nettle root could prevent from some of prostatic hyperplasia effects, so that percentage of folded alveoli in ventral lobe reduced insignificantly.

    Photoselective vaporization of benign prostatic hyperplasia (BPH) is a minimally invasive technique, consisting of vaporization of prostatic tissue by KTP green light laser with a power of 80 W. The purpose of this study was to describe our experience with this technique. KTP laser photoselective vaporization was performed in 18 patients, with lower obstructive uropathy secondary to benign prostatic hyperplasia at Santiago Military hospital from December 2005. Preoperative characteristics, postoperative results and complications were recorded. Mean prostatic volume was 55 cc (range: 24 to 78). Mean operating time was 83 minutes (range: 40 to 120). In sixteen patients, the Foley catheter was removed before 24 hours. The mean preoperative AUA score was 22 and decreased to 11.4 after 30 days. The mean maximum preoperative urine flow rate was 9 ml/s and increased to 18.2; 22.1; 22.5; 25.3 and 27.2 ml/s on days 1, 7, 14, 21 and 30, respectively. Only minor complications were observed: delayed removal of the Foley catheter (11.1%), dysuria (16.6%) and late haematuria (11.1%). KTP laser photoselective vaporization of BPH is a safe technique, that is easy to learn, with good short-term functional results, associated with low complication rate.

  5. Pancreatic α-cell hyperplasia and hyperglucagonemia due to a glucagon receptor splice mutation

    Full Text Available Glucagon stimulates hepatic glucose production by activating specific glucagon receptors in the liver, which in turn increase hepatic glycogenolysis as well as gluconeogenesis and ureagenesis from amino acids. Conversely, glucagon secretion is regulated by concentrations of glucose and amino acids. Disruption of glucagon signaling in rodents results in grossly elevated circulating glucagon levels but no hypoglycemia. Here, we describe a patient carrying a homozygous G to A substitution in the invariant AG dinucleotide found in a 3′ mRNA splice junction of the glucagon receptor gene. Loss of the splice site acceptor consensus sequence results in the deletion of 70 nucleotides encoded by exon 9, which introduces a frame shift and an early termination signal in the receptor mRNA sequence. The mutated receptor neither bound 125I-labeled glucagon nor induced cAMP production upon stimulation with up to 1 μM glucagon. Despite the mutation, the only obvious pathophysiological trait was hyperglucagonemia, hyperaminoacidemia and massive hyperplasia of the pancreatic α-cells assessed by histology. Our case supports the notion of a hepato–pancreatic feedback system, which upon disruption leads to hyperglucagonemia and α-cell hyperplasia, as well as elevated plasma amino acid levels. Together with the glucagon-induced hypoaminoacidemia in glucagonoma patients, our case supports recent suggestions that amino acids may provide the feedback link between the liver and the pancreatic α-cells.

    Full Text Available BACKGROUND: Telomerase is a reverse transcriptase enzyme that synthesizes telomeric DNA on chromosome ends. The enzyme is important for the immortalization of cancer cells because it maintains the telomeres. METHODS: Telomerase activity (TA was measured by fluorescence-based telomeric repeat amplification protocol (FTRAP assay in prostate carcinoma and benign prostatic hyperplasia (BPH. RESULTS: TA was present in 91.4% of 70 prostate cancers, 68.8% of 16 prostatic intraepithelial neoplasia (PIN, 43.3% of 30 BPH*, 21.4% of 14 atrophy and 20% of 15 normal samples adjacent to tumor. There was not any significant correlation between TA, histopathological tumor stage or gleason score. In contrast to high TA in the BPH* tissue from the cancer-bearing gland, only 6.3% of 32 BPH specimens from patients only diagnosed with BPH were telomerase activity-positive. CONCLUSIONS: These results indicate that TA is present in most prostate cancers. The high rate of TA in tissue adjacent to tumor may be attributed either to early molecular alteration of cancer that was histologically unapparent, or to the presence of occult cancer cells. Our findings suggest that the re-expression of telomerase activity could be one step in the transformation of BPH to PIN. KEY WORDS: Telomerase activity, prostate cancer, prostatic intraepithelial neoplasia, benign prostatic hyperplasia.

    To characterize the impact of inflammatory process and oxidative stress in the degree of benign prostatic hyperplasia (BPH), a common condition in which chronic inflammation plays a crucial role, we investigated the effect of different plant extract preparations in an in vivo model of BPH as new therapeutic target. BPH was made in rats with daily administration of testosterone propionate (3 mg/kg) for 14 days. Rats were randomized into different groups to receive oral administration of plant extract preparations: Serenoa repens with selenium (SeR 28.5 mg/kg associated with Se 0.005 mg/kg), Teoside (2 mg/kg), and Puryprost (14 mg/kg containing Teoside 50% 2 mg/kg and Epilobium 12 mg/kg). After 14 days, rats were killed and histological changes, prostate weight and apoptotic pathways were assayed. The results obtained demonstrated that the association of treatments reduced prostate weight and hyperplasia, while treatment with Puryprost demonstrated a greater trend of protection compared to the other treatments. Thus, our results indicate that plant extract could be considered as new useful therapy in the treatment of BPH with particular attention on Puryprost that represents a rational approach to reduce BPH through modulation of inflammatory process and anti-oxidant process.

    To determine the usefullness of the PROFUND index to assess the risk of global death after 4 years in polypathological patients. Multicenter prospective cohort (Internal Medicine and Geriatrics) study. Polypathological patients admitted between March 1st and June 30th 2011 were included. For each patient, data concerning age, sex, living at home or in a nursing residence, polypathology categories, Charlson, Barthel and Lawton-Brody indexes, Pfeiffer questionnaire, socio-familial Gijon scale, delirium, number of drugs, hemoglobin and creatinine values were gathered, and the PROFUND index was calculated. The follow-up lasted 4 years. We included 441 patients, 324 from Internal Medicine and 117 from Geriatrics, with a mean age of 80.9 (8.7) years. Of them, 245 (55.6%) were women. Heart (62.7%), neurological (41.4%) and respiratory (37.3%) diseases were the most frequent. Geriatrics inpatients were older and more dependants and presented greater cognitive deterioration. After 4 years, 335 (76%) patients died. Mortality was associated with age, dyspnoea, Barthel index<60, delirium, advanced neoplasia and≥4 admissions in the last year. The area under the curve of the PROFUND index was 0.748, 95% CI 0.689-0.806, P<.001 in Internal Medicine and 0.517, 95% CI 0.369-0.666, P=.818 in Geriatrics patients, respectively. The PROFUND index is a reliable tool for predicting long-term global mortality in polypathological patients from Internal Medicine but not from Geriatrics departments.

    The predictive value of reported early symptoms to pollen or fruits on later allergic disease is unclear. Our aim is to evaluate if symptoms to pollen and/or to fruits early in life are associated with allergic disease and sensitization to pollen at 4 years. The study included 3619 children from the Barn (Children), Allergy, Milieu, Stockholm, Epidemiology project (BAMSE) birth cohort. Reported symptoms of wheeze, sneeze or rash to birch, grass or weed, symptoms (vomiting, diarrhea, rash, facial edema, sneeze, or wheeze) to fruits including tree-nuts at 1 or 2 years of age, and definitions of asthma, rhinitis and eczema at 4 years were derived from questionnaire data. Sensitization to pollen allergens was defined as allergen-specific IgE-antibodies to any pollen (birch/timothy/mugwort) > or =0.35 kU(A)/l. At 1 or 2 years of age, 6% of the children were reported to have pollen-related symptoms, 6% had symptoms to fruits, and 1.4% to both pollen and fruits. Children with symptoms to both pollen and fruits at 1 or 2 years of age had an increased risk for sensitization to any pollen allergen at age 4 (OR(adj) = 4.4, 95% CI = 2.1-9.2). This group of children also had a substantially elevated risk for developing any allergic disease (asthma, rhinitis, or eczema) at 4 years irrespective of sensitization to pollen (OR(adj) = 8.6, 95% CI = 4.5-16.4). The prevalence of reported symptoms to pollen and fruits is very low in early childhood. However, children with early symptoms to both pollen and fruits appear to have a markedly elevated risk for allergic disease.

    To compare the worsening of structural lung disease on high-resolution computed tomography (HRCT) with changes in spirometry results in cystic fibrosis (CF) patients, and analyse factors associated with the worsening of structural lung disease over time. A total of 31 CF subjects (mean age 11.03 ± 3.67 years old) were prospectively evaluated by two HRCT and spirometry tests performed 4 years apart. HRCT abnormalities were scored using the Bhalla scoring system. Comparisons between changes on HRCT and spirometry were made for all patients, and also for groups categorized by age, sex, genotypic alterations and lung obstruction. The mean HRCT Bhalla scoring, forced expiratory volume in 1 s (FEV{sub 1} %pred.) and forced vital capacity (FVC %pred.) were 7.92 ± 3.59, 87.76 ± 20.52 and 96.54 ± 15.12, respectively. There was a significant deterioration in the Bhalla score (p < 0.01) and in certain categories: severity of bronchiectasis, peribronchial thickening, mucous plugging and bronchial divisions. Females had a more pronounced worsening of the Bhalla score than males (p = 0.048). No change over time was found in FEV{sub 1} and FVC. Only sex was associated with a deterioration in HRCT. HRCT Bhalla scoring changes statistically significantly over 4 years, but spirometry results do not. Worsening on HRCT is more evident in females. (orig.)

    Control beliefs are important psychological factors that likely contribute to heterogeneity in health outcomes for older adults. We evaluated whether control beliefs are associated with risk for 4-year mortality, after accounting for established "classic" biomedical risk factors. We also determined if an enhanced risk model with control beliefs improved identification of individuals with low vs. high mortality risk. We used nationally representative data from the Health and Retirement Study (2006-2012) for adults 50 years or older in 2006 (n = 7313) or 2008 (n = 6301). We assessed baseline perceived global control (measured as 2 dimensions-"constraints" and "mastery"), and health-specific control. We also obtained baseline data for 12 established biomedical risk factors of 4-year mortality: age, sex, 4 medical conditions (diabetes mellitus, cancer, lung disease and heart failure), body mass index less than 25 kg/m 2 , smoking, and 4 functional difficulties (with bathing, managing finances, walking several blocks and pushing or pulling heavy objects). Deaths within 4 years of follow-up were determined through interviews with respondents' family and the National Death Index. After accounting for classic biomedical risk factors, perceived constraints were significantly associated with higher mortality risk (third quartile scores odds ratio [OR] 1.37, 95% CI 1.03-1.81; fourth quartile scores OR 1.45, 95% CI, 1.09-1.92), while health-specific control was significantly associated with lower risk (OR 0.69-0.78 for scores above first quartile). Higher perceived mastery scores were not consistently associated with decreased risk. The enhanced model with control beliefs found an additional 3.5% of participants (n = 222) with low predicted risk of 4-year mortality (i.e., 4% or less); observed mortality for these individuals was 1.8% during follow-up. Compared with participants predicted to have low mortality risk only by the classic biomedical model

    We report the case of a 4-year-old boy with Ehlers-Danlos syndrome undergoing single-ventricle palliation for an unbalanced atrioventricular canal defect. No reports of single-ventricle palliation in the setting of connective tissue disorders exist in the current literature. Unique findings on the patient's preoperative imaging included a disproportionately large neoaortic root and a regurgitant atrioventricular valve, which may foretell the need for future intervention.

    This longitudinal study assessed the role of early sleep patterns in predicting attention regulation and behavior problems. Sleep of 43 infants was assessed using actigraphy at 12 months of age and then reassessed when the children were 3-4 years old. During this follow-up, their attention regulation and behavior problems were also assessed using a computerized test and parental reports. Lower quality of sleep in infancy significantly predicted compromised attention regulation and behavior problems. These findings underscore the need to identify and treat early sleep problems.

    Full Text Available Here we report the case of a 4-year-old male with severe acute pancreatitis due to hyperlipidemia, who presented with abdominal pain, metabolic abnormalities, and colonic necrosis. This colonic complication was secondary to the extension of a large peripancreatic fluid collection causing direct serosal autodigestion by pancreatic enzymes. Two weeks following the initial presentation, the peripancreatic fluid collection developed into a mature pancreatic pseudocyst, which was percutaneously drained. To our knowledge, this is the youngest documented pediatric case of colonic necrosis due to severe pancreatitis and the first descriptive pediatric case of a colonic complication due to hyperlipidemia-induced acute pancreatitis.

    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

    Interest in having alternatives in the treatment of benign prostate hyperplasia. To assess the efficacy and safety of the Urolift® system for treating the symptoms of benign prostate hyperplasia. Systematic review of the literature through searches on PubMed, Cochrane Library, CRD, Clinical Trials and EuroScan, collecting indicators of efficacy and safety. We included 5 case series and one clinical trial. The patients' mean age ranged from 65-74.3 years, and the mean prostate volume was 41-55cm3. The mean number of Urolif® implants was 3.7-5.5. The maximum follow-up in months was 24, 12 (3 studies) and one (2 studies). Improvements were found in lower urinary tract symptoms, as measured with the International Prostate Symptom Score, Benign Prostatic Hyperplasia Impact Index (BPHII), maximum urinary flow (Qmax) and postvoid residual (PVR) volume. Improvements were in found sexual dysfunction symptoms, as measured with the Sexual Health Inventory for Men (SHIM) and the Male Sexual Health Questionnaire or Ejaculatory Dysfunction (MHSQ-EjD), and in quality of life (QoL). In the clinical trial, the differences were significant for International Prostate Symptom Score, BPHII, Qmax and QoL (p<.05). The adverse effects were mild. Although the quality of evidence is low, Urolift® constitutes a good therapeutic alternative for patients with benign prostate hyperplasia. The short to medium-term results show that the technique contributes to improving lower urinary tract symptoms, with no relevant side effects, does not affect sexual function and improves quality of life. Further research is required, especially on long-term results. Copyright © 2014 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Objective. The objective of this study was to evaluate the molecular mechanism by which Qianliening capsule (QC treats benign prostatic hyperplasia (BPH. Methods. Benign prostatic hyperplasia epithelial cell line BPH-1 was treated with 0, 1.25, 2.5, and 5 mg/mL QC for 48 h, respectively. Evaluation of cell viability and observation of morphologic changes of BPH-1 cell gene expression and miRNA expression profiles were analyzed. Real-time quantitative PCR was used to confirm changes in miRNA and gene expression. GO and KEGG pathway-based approaches were used to investigate biological functions and signaling pathways affected by differentially expressed mRNAs. Results. QC inhibited BPH-1 cell proliferation. Differential expression of 19 upregulated and 2 downregulated miRNAs was observed in QC-treated BPH-1 cells compared to untreated control cells. 107 upregulated and 71 downregulated genes were identified between the two groups. Significantly enriched signaling pathways based on deregulated mRNAs were mainly involved in regulation of cell proliferation, apoptosis, and so on. Additionally, miRNA-mRNA network analysis integrated these miRNAs and genes by outlining interactions of miRNA and related genes. Conclusion. The study was the first report of differentially expressed miRNA and mRNA in QC-treated BPH-1 cells.

    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.

    Although osteopontin (OPN) is up-regulated in inflammatory bowel diseases, its role in disease pathogenesis remains controversial. The objective of this study was to determine the role of OPN in host responses to a non-invasive bacterial pathogen, Citrobacter rodentium, which serves as a murine infectious model of colitis. OPN gene knockout and wild-type mice were infected orogastrically with either C. rodentium or Luria-Bertani (LB) broth. Mouse-derived OPN(+/+) and OPN(-/-) fibroblasts were incubated with C. rodentium and attaching-effacing lesions were demonstrated using transmission electron microscopy and immunofluorescence. Colonic expression of OPN was increased by C. rodentium infection of wild-type mice. Furthermore, colonic epithelial cell hyperplasia, the hallmark of C. rodentium infection, was reduced in OPN(-/-) mice, and spleen enlargement by infection was absent in OPN(-/-) mice. Rectal administration of OPN to OPN(-/-) mice restored these effects. There was an 8- to 17-fold reduction in bacterial colonization in OPN(-/-) mice, compared with wild-type mice, which was accompanied by reduced attaching-effacing lesions, both in infected OPN(-/-) mice and OPN(-/-) mouse fibroblasts. Moreover, adhesion pedestals were restored in OPN(-/-) cells complemented with human OPN. Therefore, lack of OPN results in decreased pedestal formation, colonization, and colonic epithelial cell hyperplasia responses to C. rodentium infection, indicating that OPN impacts disease pathogenesis through bacterial attachment and altered host immune responses.

  5. Cell-to-cell communication in bilateral macronodular adrenal hyperplasia causing hypercortisolism

    2015-04-01

    Full Text Available It has been well established that, in the human adrenal gland, cortisol secretion is not only controlled by circulating corticotropin but is also influenced by a wide variety of bioactive signals, including conventional neurotransmitters and neuropeptides, released within the cortex by various cell types such as chromaffin cells, neurons, cells of the immune system, adipocytes and endothelial cells. These different types of cells are present in bilateral macronodular adrenal hyperplasia, a rare etiology of primary adrenal Cushing’s syndrome, where they appear intermingled with adrenocortical cells in the hyperplastic cortex. In addition, the genetic events which cause the disease favor abnormal adrenal differenciation that results in illicit expression of paracrine regulatory factors and their receptors in adrenocortical cells. All these defects constitute the molecular basis for aberrant autocrine/paracrine regulatory mechanisms which are likely to play a role in the pathophysiology of bilateral macronodular adrenal hyperplasia-associated hypercortisolism. The present review summarizes the current knowledge on this topic as well as the therapeutic perspectives offered by this new pathophysiological concept.

    This retrospective study aimed to evaluate bone remodeling of temporo-mandibular joints (TMJ) using computed tomography (CT) before and after condylectomy for condylar hyperplasia. TMJ bone remodeling was studied by comparing the pre and postoperative CT scan of ten patients. Qualitative evaluation was performed by two-dimensional analysis. Three-dimensional analysis superimpositions were done after digital condylar units isolation. Condylar volume modifications were measured and compared on both sides. Lastly, before and after surgery, we studied the radio-clinic correlations. After surgery, all the operated condyles developed a new cortical bone. We noticed also a thickening of the glenoid fossa. Surgical condylectomy leaded to a 43.5% volume reduction on the operated side and 2.14% on the controlateral side. On the controlateral side, most of abnormalities seen preoperatively disappeared after surgery. For two patients, the condylar resection took away over 80% of the initial volume. For these patients, we observed major radiologic modifications on the controlateral TMJ associated with symptoms of dysfunction. These problems did not worsen their quality of life. Both TMJ presented with bone remodelling after condylectomy. In condylar hyperplasia, condylectomy provides orthopaedic results on dysmorphia and removal of the pathological prechondroblastic zone. In the future, an earlier detection of this pathology may help the surgeon to treat in childhood. This would limit surgical excision and would avoid important dysmorphia. © EDP Sciences, SFODF, 2014.

    The aim of this study was to investigate developmental and noise-induced changes in central auditory processing indexed by event-related potentials in typically developing children. P1, N2, and N4 responses as well as mismatch negativities (MMNs) were recorded for standard syllables and consonants, frequency, intensity, vowel, and vowel duration changes in silent and noisy conditions in the same 14 children at the ages of 2 and 4 years. The P1 and N2 latencies decreased and the N2, N4, and MMN amplitudes increased with development of the children. The amplitude changes were strongest at frontal electrodes. At both ages, background noise decreased the P1 amplitude, increased the N2 amplitude, and shortened the N4 latency. The noise-induced amplitude changes of P1, N2, and N4 were strongest frontally. Furthermore, background noise degraded the MMN. At both ages, MMN was significantly elicited only by the consonant change, and at the age of 4 years, also by the vowel duration change during noise. Developmental changes indexing maturation of central auditory processing were found from every response studied. Noise degraded sound encoding and echoic memory and impaired auditory discrimination at both ages. The older children were as vulnerable to the impact of noise as the younger children. https://doi.org/10.23641/asha.5233939.

    The Canadian Society for Exercise Physiology (CSEP), with assistance from multiple partners, stakeholders, and researchers, developed the first Canadian Sedentary Behaviour Guidelines for the Early Years (aged 0-4 years). These national guidelines are in response to a call from health and health care professionals, child care providers, and fitness practitioners for guidance on sedentary behaviour in the early years. The guideline development process followed the Appraisal of Guidelines for Research Evaluation (AGREE) II framework. The recommendations are informed by evidence from a systematic review that examined the relationships between sedentary behaviour (predominantly screen time) and health indicators (healthy body weight, bone and skeletal health, motor skill development, psychosocial health, cognitive development, and cardio-metabolic disease risk factors) for three age groups (infants aged 900 domestic and international stakeholders, end-users, and key informants. The final guidelines state: for healthy growth and development, caregivers should minimize the time infants (aged spend being sedentary during waking hours. This includes prolonged sitting or being restrained (e.g., stroller, high chair) for more than 1 h at a time. For those under 2 years, screen time (e.g., TV, computer, electronic games) is not recommended. For children 2-4 years, screen time should be limited to under 1 h per day; less is better.

    Functional constipation (FC) often begins in the first year of life. Although standard definitions and criteria have been formulated to describe FC, these are rarely used in research and clinical practice. The aim of the study is to systematically assess how definitions and outcome measures are defined in therapeutic randomized controlled trials (RCTs) of infants with FC. PubMed, EMBASE, and Cochrane databases were searched. Studies were included if it was a (systematic review of) therapeutic RCT, children ≤4 years old, they had FC, a clear definition of constipation was provided, and were written in English. Quality was assessed using the Delphi list. A total of 1115 articles were found; only 5 studies fulfilled the inclusion criteria. Four different definitions were used, of which only 2 used the internationally accepted Rome III criteria. Defecation frequency was used as primary outcome in all included trials and stool consistency in 3 trials. Two trials involving infants investigated new infant formulas, whereas the third RCT evaluated the efficacy of a probiotic strain. The 2 trials including infants up to 4 years of age compared polyethylene glycol without electrolytes (PEG4000) with lactulose and milk of magnesia. All of the trials used nonvalidated parental diaries. Different definitions and outcome measures for FC in infants are used in RCTs. Disappointingly, there is a lack of well-designed therapeutic trials in infants with constipation. To make comparison between future trials possible, standard definitions, core outcomes, and validated instruments are needed.

    Nocardia are ubiquitous environmental saprophytes that cause pneumonia and disseminated disease in immunocompromised patients. They can also cause localized cutaneous and soft tissue infections in healthy people after direct percutaneous inoculation. Nocardia arthritis is rare in both forms of the disease. Here we present the first published case of a child with septic arthritis caused by N brasiliensis. Importantly, this otherwise well 4-year-old girl had no known history of trauma but presented with transient cutaneous lesions and a 6-week history of arthritis involving the right fourth digit proximal interphalangeal joint without accompanying fever or raised systemic inflammatory markers. She received a diagnosis of juvenile idiopathic arthritis and underwent antiinflammatory and immunosuppressant therapy. After 2 months she developed frank septic arthritis, which necessitated a surgical joint washout, from which an intraoperative swab grew N brasiliensis. The patient received 6 months of high-dose trimethoprim-sulfamethoxazole and remains well more than 4 years after treatment. This unusual case highlights the importance of considering an indolent infection from slow-growing organisms, including Nocardia, when diagnosing the oligoarthritis subtype of juvenile idiopathic arthritis. This is especially relevant when a single joint is involved and response to antiinflammatory therapy is suboptimal because antiinflammatory agents may mask evolving signs of infection.

    Intellectual disability (ID), characterized by impairments in intellectual function and adaptive behavior, affects 1-3% of the population. Many studies investigated its etiology, but few are cohort studies in middle-income countries. To estimate prevalence, etiology, and factors related to ID among children prospectively followed since birth in a Southern Brazilian city (Pelotas). In 2004, maternity hospitals were visited daily and births were identified. Live-born infants (n = 4,231) whose family lived in the urban area have been followed for several years. At the age of 2 and 4 years, performances in development and intelligence tests were evaluated using the Battelle Developmental Inventory and Wechsler Intelligence Scale, respectively. Children considered as having developmental delay were invited to attend a genetic evaluation. At 4 years of age, the prevalence of ID was 4.5%, and the etiology was classified into 5 groups: environmental (44.4%), genetic (20.5%), idiopathic (12.6%), neonatal sequelae (13.2%), other diseases (9.3%). Most children presented impairment in two or more areas of adaptive behavior. There was no difference in prenatal care attendance or maternal schooling among the groups. For about 40% of children, ID was attributed to nonbiological factors, suggesting that the rate may be reduced with appropriate interventions early in life. © 2016 The Author(s) Published by S.

    Purpose This study investigated the early rule-based sentence productions of 3- and 4-year-old children with severe speech disorders who used single-meaning graphic symbols to communicate. Method Ten 3- and 4-year-olds requiring the use of augmentative and alternative communication, who had largely intact receptive language skills, received instruction in producing up to four different semantic–syntactic targets using an Apple iPad with a communication app. A single-case, multiple-probe, across-targets design was used to assess the progress of each participant and target. Generalization to new vocabulary was assessed, and a subgroup also was taught to produce sentences using grammatical markers. Results Some targets (primarily possessor-entity) were mastered in the baseline phase, and the majority of the remaining targets were mastered during intervention. All four children who completed intervention for grammatical markers quickly learned to use the markers accurately. Conclusions Expressive language potential for preschoolers using graphic symbol–based augmentative and alternative communication systems should not be underestimated. With appropriate presentation and intervention techniques, some preschoolers with profound speech disorders can readily learn to produce rule-based messages via graphic symbols. PMID:28614575

    Full Text Available Objective: to estimate the time course of bone mineral density (BMD changes during 4-year rituximab (RTM therapy in postmenopausal women with rheumatoid arthritis (RA.Subjects and methods. Seventy-nine postmenopausal women with a valid diagnosis of RA were followed up. According to the basic therapy option, all the patients were allocated into two groups: 1 44 patients who received combination therapy with RTM and methotrexate (MT; 2 35 patients who had MT monotherapy. BMD was estimated by dual-energy X-ray absorptiometry using an Excell XR-46 stationary dualenergy X-ray bone densitometer (Norland, USA.Results. There was a statistically significant increase in femoral neck BMD and T score as compared to the baseline values in the RTM group after 3 years of follow-up. The MT monotherapy group showed no statistically significant densitometric changes in the femoral neck. The similar positive BMD changes were observed 4 years following RTM and MT therapy.Conclusion. Following 2 therapy cycles, femoral neck BMD parameters were noted to be stabilized in the patients with RA. After 3 therapy cycles, there was a positive densitometric change that remained by the fourth therapy cycle.

  15. Dietary heme-mediated PPARα activation does not affect the heme-induced epithelial hyperproliferation and hyperplasia in mouse colon.

    Directory of Open Access Journals (Sweden)

    Noortje Ijssennagger

    Full Text Available Red meat consumption is associated with an increased colon cancer risk. Heme, present in red meat, injures the colon surface epithelium by luminal cytotoxicity and reactive oxygen species. This surface injury is overcompensated by hyperproliferation and hyperplasia of crypt cells. Transcriptome analysis of mucosa of heme-fed mice showed, besides stress- and proliferation-related genes, many upregulated lipid metabolism-related PPARα target genes. The aim of this study was to investigate the role of PPARα in heme-induced hyperproliferation and hyperplasia. Male PPARα KO and WT mice received a purified diet with or without heme. As PPARα is proposed to protect against oxidative stress and lipid peroxidation, we hypothesized that the absence of PPARα leads to more surface injury and crypt hyperproliferation in the colon upon heme-feeding. Heme induced luminal cytotoxicity and lipid peroxidation and colonic hyperproliferation and hyperplasia to the same extent in WT and KO mice. Transcriptome analysis of colonic mucosa confirmed similar heme-induced hyperproliferation in WT and KO mice. Stainings for alkaline phosphatase activity and expression levels of Vanin-1 and Nrf2-targets indicated a compromised antioxidant defense in heme-fed KO mice. Our results suggest that the protective role of PPARα in antioxidant defense involves the Nrf2-inhibitor Fosl1, which is upregulated by heme in PPARα KO mice. We conclude that PPARα plays a protective role in colon against oxidative stress, but PPARα does not mediate heme-induced hyperproliferation. This implies that oxidative stress of surface cells is not the main determinant of heme-induced hyperproliferation and hyperplasia.

    Marrow adipose deposition is observed during aging and in association with extended periods of immobility. The objective of this study was to determine the contribution of adipocyte hypertrophy and hyperplasia to bone marrow fat deposition induced by immobilization of the rat knee joint for 2, 4, 16 or 32 weeks. Histomorphometric analyses compared immobilized to sham-operated proximal tibia from age and gender matched rats to assess the contribution of aging and duration of immobilization on the number and size of marrow adipocytes. Results indicated that marrow adipose tissue increased with the duration of immobilization and was significant larger at 16 weeks compared to the sham-operated group (0.09956±0.13276mm 2 vs 0.01990±0.01100mm 2 , p=0.047). The marrow adipose tissue was characterized by hyperplasia of adipocytes with a smaller average size after 2 and 4 weeks of immobilization (at 2 weeks hyperplasia: 68.86±33.62 vs 43.57±24.47 adipocytes/mm 2 , p=0.048; at 4 weeks hypotrophy: 0.00036±0.00019 vs 0.00046±0.00023mm 2 , p=0.027), and by adipocyte hypertrophy after 16 weeks of immobilization (0.00083±0.00049 vs 0.00046±0.00028mm 2 , p=0.027) compared to sham-operated. Both immobilized and sham-operated groups showed marrow adipose conversion with age; immobilized (p=0.008; sham: p=0.003). Overall, fat deposition in the bone marrow of the proximal rat tibia epiphysis and induced by knee joint immobilization was characterized by hyperplasia of small adipocytes in the early phase and by adipocyte hypertrophy in the later phase. Mediators of marrow fat deposition after immobilization and preventive countermeasures need to be investigated. Copyright © 2017 Elsevier GmbH. All rights reserved.

    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.

    Over the last 10 years, 240 cases of hyperplasic lymphadenitis have been systematically tested in our institution for the presence of the human immunodeficiency virus (HIV). This series comprised patients between 15 and 90 years (median of age: 38.51) without a past history of HIV infection. The technical approach consisted in an immunohistochemical procedure with a monoclonal antibody against the p24-gag protein of HIV. Among the 240 cases, 105 had a true follicular hyperplasia. Overall, this survey found that 4 cases (3 males and 1 female) were positive for p24-gag without previous knowledge of HIV infection (4/240=1.66%). HIV infection was further confirmed by serologic and molecular investigations in all cases. These results were seen exclusively in those cases with prominent follicular hyperplasia (4/105=3.80%). Staining with the anti-p24 antibody was intense and restricted to the follicular dendritic cell networks. In one case, beside hyperplasic germinal centers, one could see a regressed onion bulblike structure. One important conclusion can be drawn from this study. A systematic research of HIV proteins should be performed in all lymph node biopsies with marked follicular hyperplasia, in a context of polyadenopathy, fever, and general status alteration. Besides giving an accurate diagnosis, this approach may be helpful in cases of recent infection in which anti-p24 antibodies are not yet detectable in the serum.

    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

    Three experiments examined whether cooperation or competition affects 4-year-old children's reasoning about other people's desires-which differed from their own-in a gift selection task. Experiment 1 (N=72) found that children's performance in selecting an adult-preferred gift for an adult experimenter was enhanced by a short period of preceding cooperative, but not competitive or individualistic, play with the experimenter. Experiment 2 (N=24) ruled out the alternative explanation that children resisted satisfying their opponent after competition. Experiment 3 (N=48) replicated the cooperation advantage in selecting a gift for someone else, indicating that children's understanding of diverse desires was generally improved by cooperation but not competition. These findings support the constructivist view of social development and highlight the advantage of cooperation. Copyright © 2016 Elsevier Inc. All rights reserved.

    Ectodermal dysplasia (ED) is an inherited disorder that affects ectodermally derived organs, such as teeth. Pathogenesis is thought to involve an altered epithelium-mesenchymal interaction. ED patients have oligodontia (or sometimes anodontia) in addition to other abnormalities involving the skin, sweat glands, or hair. Many different subtypes have been introduced in the literature. This article describes the case of a 4-year-old patient who, after being diagnosed with ED, was put on a treatment plan that involved mandibular implants, reshaping of the maxillary primary central incisors, and prosthetic dental rehabilitation. Due to the child's rapid growth, both dentures were changed 9 months post-treatment. Two years post-treatment, the maxillary denture was changed again and the child was placed under close supervision.

    In this 4-year prospective cohort study, children with a reading and spelling disorder, children with a spelling impairment, and children without a reading and/or spelling disorder (control group) in a transparent orthography were identified in third grade, and their emergent literacy performances in kindergarten compared retrospectively. Six hundred and forty-two Italian children participated. This cohort was followed from the last year of kindergarten to third grade. In kindergarten, the children were assessed in phonological awareness, conceptual knowledge of writing systems and textual competence. In third grade, 18 children with a reading and spelling impairment and 13 children with a spelling impairment were identified. Overall, conceptual knowledge of the writing system was the only statistically significant predictor of the clinical samples. No differences were found between the two clinical samples.

    Full Text Available Urethral caruncle (UC is a benign fleshy outgrowth at the urethral meatus. It was first described by Samuel Sharp in 1750 and occurs mainly at the posterior lip of the urethra, and the exact aetiology is still uncertain. More often it was seen in the postmenopausal women, and only few cases are reported in young girls. Patients may be asymptomatic and could find this as an incidental finding or they may present with symptoms such as dysuria, bleeding per vagina, haematuria, a mass protruding through vagina, and acute retention of urine. Here, we report the case history of a 4-year-old girl presented with vaginal bleeding which was taken as she has attended menarche and found to have urethral caruncle which was the cause for bleeding. Histology confirmed the diagnosis, and girl was completely cured following surgical excision.

    A primary hepatic neuroendocrine tumour (PHNET) is a very rare disease. The liver represents the preferential site for neuroendocrine tumors' metastases. A 45-year old Caucasian female who presented with nausea, vomiting, diarrhea, accompanied by diffuse abdominal pain was found to have on contrast-enhanced computer tomography an encapsulated, partially cystic liver mass. The patient underwent an uneventful left atypical hepatic resection. Histopatological and immunohistochemical examination revealed a slowly growing (G1) hepatic neuroendocrine tumour. Post surgery, the specific neuroendocrine markers (serum Chromogranin A and 24h urinary 5 hydroxy-indolacetic acid) were within normal range. Further functional imaging investigations were performed. No other lesions were found making probable the diagnosis of PHNET. The patient is presently after 4 years of follow-up with no local recurrence or distant metastases. The diagnosis of PHNET is a medical challenge that requires a thorough long term follow-up in order to exclude an occult primary neuroendocrine tumour.

    The great decline in infant mortality in Chile in the last 2 decades provokes interest in the current situation in child mortality (for children 1-4 years of age). For the present analysis, central death rates and probabilities of dying are used, calculated with Greville's method from birth and death data. Mortality trends of the group between 1961-78, sex differentials, and causes of death are studied. The findings indicate that mortality in this age group has declined dramatically during the period of analysis, mainly due to the decrease in mortality from respiratory diseases, diarrhea, and diseases avoidable through vaccination. To attain the future approach of the Chilean rate to that of more developed countries, the reduction of mortality from respiratory diseases and diarrhea should continue together with the achievement of substantial reduction in mortality from violence and accidents. This, the primary cause of death in children, ages 1-4, has not varied during the period under study. (author's)

    Full Text Available The paper describes a clinical case of a local recurrence of tubulocystic carcinoma (TCC in a 46-year-old man, a relatively good course (the relapse occurred after 4 years, who has been successfully operated on and is being followed up. This disease is a rare renal malignancy and, until recently, it has been referred to as collecting tubular carcinoma. However, this disease has come to be regarded as an independent nosological entity, by taking into account its certain morphological, immunohistohemical, and cytogenetic characteristics, as well as the nature of its course. About 80 TCC cases have been described to date. Further study of this disease and other rare renal malignancies will allow the more accurate elaboration of management tactics for such patients in terms of certain prognostic factors, which calls for a larger number of cases of this disease.

    Full Text Available Lipomas are commonest benign tumor and can occur at any part of the body, but intermuscular lipomas are very rare and usually occur at middle age or later. Intermuscular lipomas remain hidden till they attain a large size. They commonly appear on anterior abdominal wall. We treated a case of intermuscular lipoma in a 4-year-old girl. It presented as a bulge at right iliac fossa during straining; its location and symptoms were similar to that of Spigelian hernia. Actual diagnosis was made under general anesthesia and complete surgical excision was done. This is a rare mode of presentation of an intermuscular lipoma. Intermuscular lipoma of the abdominal wall at this young age was not reported earlier.

    Recent studies have revealed the prognostic role of the gamma gap, the total serum proteins concentration minus the albumin concentration, for predicting all-cause mortality among adults. This study aims to investigate the relationship between the gamma gap and all-cause mortality among nonagenarians and centenarians via a secondary data analysis of a prospective observational study. The analysis included 801 participants (260 men and 541 women, mean age: 93.7 ± 3.5 years), 46 of which were lost at the 4-year follow-up. The mean gamma gap was 2.7 ± 0.5 g/dl. After adjusting for relevant confounders, the gamma gap was significantly associated with 4-year all-cause mortality (hazard ratio [HR] per 1-SD = 1.22, 95% confidential interval [CI]: 1.12-1.78). Using different cut-off points, the elevated gamma gap could be defined as ≥2.9, 3.0, 3.1, or 3.2 g/dl. The relevant HRs and 95% CIs of the elevated gamma gap for predicting mortality were 1.27 (1.12-1.90), 1.29 (1.03-1.78), 1.21 (1.23-1.66), and 1.26 (1.09-1.69), respectively. In conclusion, the gamma gap is an independent prognostic factor for long-term mortality in nonagenarians and centenarians. A value greater than or equal to 3.1 g/dl may define an elevated gamma gap, but further studies are required.

    Allergy immunotherapy during early childhood may have potential benefits for the prevention of asthma and allergy morbidity. However, subcutaneous immunotherapy has not yet been prospectively researched in children younger than 4 years, primarily because of safety concerns, including the fear and psychological distress young children may experience with repeated needle injections. To quantify fear in atopic children younger than 4 years with a history of wheezing who are receiving subcutaneous immunotherapy. Fear of injection was graded during a total of 788 immunotherapy injection visits in 18 children (age, 37 months; SD, 9 months) receiving subcutaneous allergy immunotherapy. The parent and the injection nurse assigned fear scores on a scale of 0 to 10 after each injection visit. At the time of analysis, children had a median of 49 injection visits (range, 12-88) during a median study period of 81.5 weeks (range, 15-165 weeks). Fifteen children (83%) lost their fear of injections during the study. A fear score of 0 was achieved after a mean of 8.4 visits (SD, 7.4). The more injection visits were missed, the more likely children were to retain fear of injections (hazard ratio, 0.13; 95% confidence interval, 0.02-1.02; P=.05). Age, adverse events, number of injections at each visit, and change of injection personnel were not associated with increased fear. Our analysis suggests that most children receiving weekly subcutaneous immunotherapy lose their fear of injections during the treatment course. Children with increased intervals between visits may be at higher risk of experiencing fear of injections. clinicaltrial.gov identifier NCT01028560.

    It is well known that acuity slowly decreases in the later decades of life. We wish to determine the extent by which 4-year longitudinal acuity changes can be accounted for by changes in optical quality, or combination of optical quality metrics and of age between 50 and 80 years. High-contrast logMAR acuity, 35 image quality metrics, 4 intraocular scatter metrics, and 4 Lens Opacification Classification System III metrics and entry age were measured on one eye of each of the 148 subjects. Acuity change between baseline and the last visit was regressed against change in each metric for all eyes and a faster changing subset of 50 eyes with a gain or loss of four or more letters. Average change across 148 subjects was a 1.6 ± 4 letter loss (t148 = 4.31, p model for faster changing eyes included change in point spread function entropy, posterior subcapsular cataract, and trefoil and baseline age (sequential r adjusted values of 0.19, 0.27, 0.32, and 0.34, respectively; p = 1.48 × 10 for the full four-factor model). The same variables entered the multiple-regression model for the full 148 data set where most of the acuity measurements were within test-retest error and accounted for less of the variance (r adjusted = 0.15, p = 2.37 × 10). Despite being near noise levels for the measurement of acuity, change in optical quality metrics was the most important factor in eyes that lost or gained four or more letters of acuity. These findings should be generalizable given that our 4-year acuity change is essentially identical to other studies and indicate that these optical quality markers can be used to help identify those on a faster track to an acuity change.

    Full Text Available Although an increased level of the prostate-specific antigen can be an indication for prostate cancer, other reasons often lead to a high rate of false positive results. Therefore, an additional serological screening of autoantibodies in patients' sera could improve the detection of prostate cancer. We performed protein macroarray screening with sera from 49 prostate cancer patients, 70 patients with benign prostatic hyperplasia and 28 healthy controls and compared the autoimmune response in those groups. We were able to distinguish prostate cancer patients from normal controls with an accuracy of 83.2%, patients with benign prostatic hyperplasia from normal controls with an accuracy of 86.0% and prostate cancer patients from patients with benign prostatic hyperplasia with an accuracy of 70.3%. Combining seroreactivity pattern with a PSA level of higher than 4.0 ng/ml this classification could be improved to an accuracy of 84.1%. For selected proteins we were able to confirm the differential expression by using luminex on 84 samples. We provide a minimally invasive serological method to reduce false positive results in detection of prostate cancer and according to PSA screening to distinguish men with prostate cancer from men with benign prostatic hyperplasia.

    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.

    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

    Highlights: • A comprehensive study of corrosion characteristics of a naturally corroded RC beam. • New insights on the role of cracks in corrosion propagation of steel in concrete. • EMPA and 3D laser scanning provide quantitative analysis of corroded rebar. - Abstract: This work studies the corrosion characteristics of reinforcement in a 4-year naturally corroded concrete beam after accelerated chloride penetration. The results show that the presence of transverse cracks in the tension surface of reinforced concrete beam can globally exacerbate the loss of cross-sectional area of rebar. However, there is no strong correlation between the width of transverse cracks, with the width of longitudinal cracks and loss of cross-sectional area of corroded rebar at a specific location. The self-healing of cracks and sacrificing roles of stirrups at crack tips seem to reduce the impacts of cracks on the corrosion propagation.

    Background. Mechanical complications in the use of indwelling central venous catheters (CVCs) such as the Broviac catheter (BC) include kinking, occlusion, dislocation or leaking. We report on a mechanical complication after using a repair kit for the BC. Method. A 4-year old boy, suffering from multiple endocrine neoplasia type 2a (MEN 2a), intestinal aganglionosis (Hirschsprung's disease), and short bowel syndrome, required a BC for home parenteral nutrition. Result. Due to recurrent leakage of the BC, 5 subsequent repairs were necessary within seven months. During one repair a metallic tube belonging to the repair kit was found to have migrated proximally to the skin entrance level within the BC and requiring surgical removal. Conclusion. To our knowledge, this is the first report focusing on such a serious complication using a BC and its repair kit. The proximal migration of this metallic tube constitutes a distinct theoretical risk of endothoracic foreign body embolization.

    Effects of joint attention were addressed on 3- to 4-year-olds' performance in a verbal false-Belief Test (FBT), featuring the experimenter as co-watcher rather than narrator. In two experiments, children (N = 183) watched a filmed-FBT jointly with a test leader, disjointed from a test leader, or alone. Children attending jointly with a test leader were more likely to pass the FBT compared with normative data and to spontaneously recall information indicating false-belief understanding, suggesting that joint attention strengthens the plausibility of the FBT and renders plot-critical information more salient. In a third experiment (N = 59), results were replicated using a typical, image-based FBT. Overall findings highlight the profound impact of experimenter as social context in verbal FBTs, and link recall of specific story features to false-belief understanding. © 2018 Society for Research in Child Development.

    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.

    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.

    The effects of bread consumption change over time on anthropometric measures have been scarcely studied. We analysed 2213 participants at high risk for CVD from the PREvención con DIeta MEDiterránea (PREDIMED) trial to assess the association between changes in the consumption of bread and weight and waist circumference gain over time. Dietary habits were assessed with validated FFQ at baseline and repeatedly every year during 4 years of follow-up. Using multivariate models to adjust for covariates, long-term weight and waist circumference changes according to quartiles of change in energy-adjusted white and whole-grain bread consumption were calculated. The present results showed that over 4 years, participants in the highest quartile of change in white bread intake gained 0·76 kg more than those in the lowest quartile (P for trend = 0·003) and 1·28 cm more than those in the lowest quartile (P for trend bread consumption and anthropometric measures. Gaining weight (>2 kg) and gaining waist circumference (>2 cm) during follow-up was not associated with increase in bread consumption, but participants in the highest quartile of changes in white bread intake had a reduction of 33 % in the odds of losing weight (>2 kg) and a reduction of 36 % in the odds of losing waist circumference (>2 cm). The present results suggest that reducing white bread, but not whole-grain bread consumption, within a Mediterranean-style food pattern setting is associated with lower gains in weight and abdominal fat.

    2013-01-01

    Prostatic artery embolization (PAE) has emerged as an alternative to surgical treatments for benign prostatic hyperplasia (BPH). Patient selection and refined technique are essential for good results. Urodynamic evaluation and magnetic resonance imaging are very important and technical limitations are related to elderly patients with tortuous and atherosclerotic vessels, anatomical variations, difficulty visualizing and catheterizing small diameter arteries feeding the prostate, and the potential risk of bladder and rectum ischemia. The use of small-diameter hydrophilic microcatheters is mandatory. Patients can be treated safely by PAE with low rates of side effects, reducing prostate volume with clinical symptoms and quality of life improvement without urinary incontinence, ejaculatory disorders, or erectile dysfunction. A multidisciplinary approach with urologists and interventional radiologists is essential to achieve better results

    A spectrum of myths and misconceptions about congenital adrenal hyperplasia (CAH) is prevalent among the parents of affected children in India. The perceptions of parents may affect several aspects of these children's management, and to explore these perceptions we carried out a cross-sectional questionnaire-based descriptive study during May 2010. Twenty-eight individuals (17 males and 11 females), parents of 22 affected children aged parents of misconceptions about CAH. These misconceptions were resulting in potentially harmful practices, and in addition there was immense societal pressure on the families as a result of ignorance and myths about the disorder. There is a need for regular CAH education and interaction programs to provide an acceptable platform for the parents and patients, where their concerns can be expressed and shared and their requirements addressed appropriately by a multidisciplinary team.

    Full Text Available Neointimal hyperplasia as a consequence of vascular injury is aggravated by inflammatory reaction and oxidative stress. The α7 nicotinic acetylcholine receptor (α7nAChR is a orchestrator of cholinergic anti-inflammatory pathway (CAP, which refers to a physiological neuro-immune mechanism that restricts inflammation. Here, we investigated the potential role of CAP in neointimal hyperplasia using α7nAChR knockout (KO mice. Male α7nAChR-KO mice and their wild-type control mice (WT were subjected to wire injury in left common carotid artery. At 4 weeks post injury, the injured aortae were isolated for examination. The neointimal hyperplasia after wire injury was significantly aggravated in α7nAChR-KO mice compared with WT mice. The α7nAChR-KO mice had increased collagen contents and vascular smooth muscle cells (VSMCs amount. Moreover, the inflammation was significantly enhanced in the neointima of α7nAChR-KO mice relative to WT mice, evidenced by the increased expression of tumor necrosis factor-α/interleukin-1β, and macrophage infiltration. Meanwhile, the chemokines chemokine (C-C motif ligand 2 and chemokine (CXC motif ligand 2 expression was also augmented in the neointima of α7nAChR-KO mice compared with WT mice. Additionally, the depletion of superoxide dismutase (SOD and reduced glutathione (GSH, and the upregulation of 3-nitrotyrosine, malondialdehyde and myeloperoxidase were more pronounced in neointima of α7nAChR-KO mice compared with WT mice. Accordingly, the protein expression of NADPH oxidase 1 (Nox1, Nox2 and Nox4, was also higher in neointima of α7nAChR-KO mice compared with WT mice. Finally, pharmacologically activation of CAP with a selective α7nAChR agonist PNU-282987, significantly reduced neointima formation, arterial inflammation and oxidative stress after vascular injury in C57BL/6 mice. In conclusion, our results demonstrate that α7nAChR-mediated CAP is a neuro-physiological mechanism that inhibits neointima

    Preservation and loss to forgetting of autobiographical memories is a focus in both the adult and developmental literatures. In both, there are comparative arguments regarding rates of forgetting. Children are assumed to forget autobiographical memories more rapidly than adults, and younger children are assumed to forget more rapidly than older children. Yet few studies can directly inform these comparisons: few feature children and adults, and few prospectively track the survival of specific autobiographical memories over time. In a 4-year prospective study, we obtained autobiographical memories from children 4, 6, and 8 years, and adults. We tested recall of different subsets of the events after 1, 2, and 3 years. Accelerated rates of forgetting were apparent among all child groups relative to adults; within the child groups, 4- and 6-year-olds had accelerated forgetting relative to 8-year-olds. The differences were especially pronounced in open-ended recall. The thematic coherence of initial memory reports also was a significant predictor of the survival of specific memories. The pattern of findings is consistent with suggestions that the adult distribution of autobiographical memories is achieved as the quality of memory traces increases (here measured by thematic coherence) and the rate of forgetting decreases.

    Congenital toxoplasmosis is caused by Toxoplasma gondii. The incidence of death due to congenital toxoplasmosis in Japan from 1974 to 2007 was calculated using the autopsy database of the Japanese Society of Pathology and vital statistics from the Ministry of Health, Labour and Welfare. Two neonatal deaths due to congenital toxoplasmosis were reported during that time. As there were 161,195 neonatal deaths during this period and 32,465 autopsies were performed, the yearly neonatal death from congenital toxoplasmosis was calculated as 2 × 161,195/32,465/34 = 0.29 and the autopsy rate as 32,465/161,195 = 0.2014 (20.14%). The calculated number of annual deaths in infants was 0.82 and in children aged 1-4 years it was 2.09; thus, although few, deaths from congenital toxoplasmosis do still occur in neonates, infants, and young children. Therefore, obstetricians and pediatricians should be aware of the potential for congenital toxoplasmosis, and pregnant women should make every effort to avoid T. gondii infection. © 2014 Japan Pediatric Society.

    Ectodermal dysplasia (ED) is an anomaly determined by genetic factors that alter ectodermal structures such as skin, hair, nails, glands, and teeth. Children affected by this condition require extensive, comprehensive, and multidisciplinary treatment. An 8-year-old female patient visited the Dentistry Clinic of the Federal University of Santa Catarina with the chief complaint of multiple missing teeth. The mother reported that the patient had ED. Clinical and radiographic examination revealed the congenital absence of several primary and permanent teeth and tooth germs. Subsequent oral rehabilitation comprised the application of a maxillary denture and mandibular implant-supported fixed prosthesis. The child was also supplied with a wig for further enhancement of esthetics aimed at improving her emotional wellbeing. Psychological follow-up and speech therapy were also provided. After 4 years of follow-up, implant-supported oral rehabilitation has proved to be a satisfactory treatment option, allowing restoration of masticatory, phonetic, and esthetic function, as well as an improvement in the patient's self-esteem and social wellbeing.

    The National Health and Nutrition Survey 2006 (ENSANUT in Spanish) reported high rates of under-nutrition in children of Yucatan. Is food intake the main cause of under-nutrition in children of the state of Yucatan, Mexico? Identify the primary causes of under-nutrition in pre-school children in Yucatan. A sample of 111 children (59 girls and 52 boys) aged 1-4 years representing Yucatan was taken from a database of ENSANUT 2006 and another national survey, a federal poverty mitigation programme for the state of Yucatan, Mexico entitled "Oportunidades". A human ecology approach together with life history theory was used to analyse anthropometric indices and food intake data from the ENSANUT 2006 and "Oportunidades". Height and weight were significantly correlated to age and total food intake. No correlations were found between age and anthropometric indices or food intake rates. The children in the sample had adequate protein intake but deficient energy intake. No correlation was identified between nutritional status and food intake rates. Pre-schoolers with higher weight-for-height values achieved greater height-for-age. These relationships can be explained by life history theory in that energy intake was used either for maintenance (combating and recovering from infections) or growth. The poor relationship between food intake rates and nutritional status is probably explained by the interaction between high disease incidence and insufficient energy intake. These conditions are endemic in Yucatan due to widespread poor housing, water and sanitation conditions.

    To compare the effects of Montessori education and traditional education on the intellectual development in children aged 2 to 4 years. Children aged between 2 to 3 years who were enrolled in a kindergarten in September 2006 were randomly assigned to the Montessori education and the traditional education groups. In addition to receiving the traditional education, the Montessori education group participated in the two-hour Montessori pedagogical activities every day. The intellectual development was evaluated by the Neuropsychological Development Examination Format for Children Aged 0~6 years published by Capital Pediatrics Research Institute at enrollment and one year after the trial. There were no significant differences in the intelligence growth level between the Montessori education and the traditional education groups at enrollment. After one year, the levels of fine movements, adaptation ability, language, and social behavior developments in the Montessori education group were significantly higher than those in the traditional education group (pdevelopment quotient in the Montessori education group were also higher than those in the traditional education group (peducation can promote the development of large motor ability, fine movements, language, and social behavior in children.

    To examine the course of Eating Disorder NOS (EDNOS) compared with anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Prospective study of 385 participants meeting DSM-IV criteria for AN, BN, BED, and EDNOS at three sites. Recruitment was from the community and specialty clinics. Participants were followed at 6-month intervals during a 4-year period using the Eating Disorder Examination as the primary assessment. EDNOS remitted significantly more quickly that AN or BN but not BED. There were no differences between EDNOS and full ED syndromes, or the subtypes of EDNOS, in time to relapse following first remission. Only 18% of the EDNOS group had never had or did not develop another ED diagnosis during the study; however, this group did not differ from the remaining EDNOS group. EDNOS appears to be a way station between full ED syndromes and recovery, and to a lesser extent from recovery or EDNOS status to a full ED. Implications for DSM-V are examined.

    Full Text Available The scopolamine patch is usually used to reduce postoperative nausea and vomiting associated with anesthesia and/or surgery. It is also commonly used for the prevention of motion sickness. Transdermal scopolamine patches have been used for decades and there are few reports in the literature of toxic psychosis associated with the product. Most documented cases of acute psychosis following administration of scopolamine or other anticholinergic agents have been from the adult population. Here we present a 4-year-old boy with deteriorated cognitive function and changed mental status acutely. Besides flushing skin and psychotic behaviors including bizarre actions, hallucinations, aggressive behavior, hyperactivity, and incoherent speech were also noticed. Symptoms and signs were resolved after removal of scopolamine patch and conservative management. This case is possibly one of the youngest patients to exhibit such toxic effects. We hope to relay information about common agents with anticholinergic effects to clinical practitioners and remind that drug-induced psychosis should be considered in children with acute changes in behavior.

    Full Text Available Background. Laparoscopic hysterectomies are increasingly popular; a morcellation device is often used. Although there are some clear benefits, morcellation of tissue does have potential risks. Case Presentation. In this case report we present a 55-year-old woman with an abdominal tumour 4 years after a laparoscopic hysterectomy using a morcellation device. Postoperative histological analysis, compromised by morcellated tissue, showed benign myoma. Because of the benign tumour no follow-up was performed. The patient presented now with an abdominal tumour, and she was scheduled for surgical removal of the tumour. During abdominal surgery the tumour appeared malignant and biopsies were taken. Histological analysis showed leiomyosarcoma, and the patient was referred to a third care centre for further treatment. The patient recovered quickly after abdominal removal of the tumour; however, after 7 months the patient had complaints and a CT scan showed a large intra-abdominal tumour with possible lung metastasis. The patient received palliative chemotherapy and died after 10 months. Conclusion. This case shows that although unexpected after a hysterectomy, a leiomyosarcoma has to be considered in case of a suspect tumour in the lower abdomen.

    We have performed a 4-year simulation with the Middle Atmosphere General Circulation Model MAECHAM5/MESSy, while slightly nudging the model's meteorology in the free troposphere (below 113 hPa) towards ECMWF analyses. We show that the nudging 5 technique, which leaves the middle atmosphere almost entirely free, enables comparisons with synoptic observations. The model successfully reproduces many specific features of the interannual variability, including details of the Antarctic vortex structure. In the Arctic, the model captures general features of the interannual variability, but falls short in reproducing the timing of sudden stratospheric warmings. A 10 detailed comparison of the nudged model simulations with ECMWF data shows that the model simulates realistic stratospheric temperature distributions and variabilities, including the temperature minima in the Antarctic vortex. Some small (a few K) model biases were also identified, including a summer cold bias at both poles, and a general cold bias in the lower stratosphere, most pronounced in midlatitudes. A comparison 15 of tracer distributions with HALOE observations shows that the model successfully reproduces specific aspects of the instantaneous circulation. The main tracer transport deficiencies occur in the polar lowermost stratosphere. These are related to the tropopause altitude as well as the tracer advection scheme and model resolution. The additional nudging of equatorial zonal winds, forcing the quasi-biennial oscillation, sig20 nificantly improves stratospheric temperatures and tracer distributions.

    Invasive spiders pose potential threats to native spiders. In 2002, the European spider Linyphia triangularis (Clerck, 1757) (Araneae: Linyphiidae) was discovered in all but one county in Maine. At Acadia National Park, we conducted a 4-year study of L. triangularis and three native linyphiid species of a similar size (Frontinella communis (Hentz, 1850), Pityohyphantes subarcticus Chamberlin and Ivie, 1943, and Neriene radiata (Walckenaer, 1842)). Using line-transect surveys, we measured population densities in coastal and forest habitat. The density of L. triangularis varied across years but was always significantly higher on the coast than in the forest. In contrast, only one native species was present on the coast and at very low numbers. Coastal L. triangularis were larger and in better condition than those in the forest, and numbers and biomass of insect prey were also higher on the coast. In 2 years, we also conducted transects at a second coastal location in Maine where the invader was at low density. At that site, native densities were substantially higher than at either Acadia site. Our data are consistent with the hypothesis that L. triangularis is reducing populations of native spiders. Companion studies suggest that L. triangularis negatively impacts natives by usurping both web sites and webs.

    Full Text Available The aim of this study was to analyze the psychosocial effects of severe caries in 4-year-old children in Recife, Pernambuco, Brazil. The clinical examination was conducted by a single examiner in order to select children with severe caries and caries-free (kappa = 1. Of the 861 children examined, 77 (8.1% had severe caries and 225 (23.6% were caries-free. Data were collected by applying validated questionnaires answered by the parents or guardians. Most of the parents or guardians of children with severe caries reported that their children complained of toothache (72.7%, and a significant portion stated that their children had problems eating certain kinds of food (49.4% and missed school (26.0% because of their teeth. Most of the parents or guardians of children with severe caries (68.8% stated that oral health affects their children's life, while the same was stated by 9.8% of the parents or guardians of the caries-free children. Severe caries was found to have a negative impact on children's oral health-related quality of life.

    Little attention has so far been focused on follow ups of women's long-term recovery after a myocardial infarction (MI), especially from a comprehensive perspective. The aim of this study was to prospectively determine women's self-rated health after a first MI from a comprehensive perspective on recovery over a 4-year period. Consecutively chosen women (n=240) who had suffered a first MI were asked to complete a self-rated questionnaire regarding health (including not only biophysical, but also behavioral, emotional, social and working conditions) before being discharged from hospital as well as 1 and 4 years later. The results were analyzed by descriptive and inferential statistics. Health improvements, especially during the first year, could be observed in the women's behavioral condition regarding their attitude to diet consciousness, exercise, simultaneous capability and smoking behavior as well as in the emotional condition regarding their stressful life events, depressed mood and loss of control. In the social condition, the women considered that the healthcare professionals had improved their support over time as well as treating the women's complaints more seriously. Regarding the working condition, the women felt that they were being controlled at work, especially during the first year after the MI. Based on a comprehensive perspective on women's recovery after a first MI, a favorable development of the women's health was observed in the behavioral and emotional conditions while deterioration in the social and working conditions was observed over time. Thus, further efforts are needed in the two latter conditions by means of further studies in combination with greater support from healthcare professionals.

    Full Text Available A phase II clinical trial with glutamic acid decarboxylase (GAD 65 formulated with aluminium hydroxide (GAD-alum has shown efficacy in preserving residual insulin secretion in children and adolescents with recent-onset type 1 diabetes (T1D. We have performed a 4-year follow-up study of 59 of the original 70 patients to investigate long-term cellular and humoral immune responses after GAD-alum-treatment. Peripheral blood mononuclear cells (PBMC were stimulated in vitro with GAD(65. Frequencies of naïve, central and effector memory CD4+ and CD8+ T cells were measured, together with cytokine secretion, proliferation, gene expression and serum GAD(65 autoantibody (GADA levels. We here show that GAD-alum-treated patients display increased memory T-cell frequencies and prompt T-cell activation upon in vitro stimulation with GAD(65, but not with control antigens, compared with placebo subjects. GAD(65-induced T-cell activation was accompanied by secretion of T helper (Th 1, Th2 and T regulatory cytokines and by induction of T-cell inhibitory pathways. Moreover, post-treatment serum GADA titres remained persistently increased in the GAD-alum arm, but did not inhibit GAD(65 enzymatic activity. In conclusion, memory T- and B-cell responses persist 4 years after GAD-alum-treatment. In parallel to a GAD(65-induced T-cell activation, our results show induction of T-cell inhibitory pathways important for regulating the GAD(65 immunity.

    Statement of the Problem: Dental caries in infants and young children is prevalent worldwide; its magnitude and associated factors vary between communities because of cultural and social economic differences. No such information was available for pre-school children in Mbeya city. Purpose: To determine dental caries status and associated factors in 2 to 4-year-old children in Mbeya city. Materials and Method: A cross sectional study was conducted among 525 children aged 2-4 years and their parents/caregivers. Caries was assessed using caries assessment spectrum and treatment index, oral hygiene by visual inspection for visible plaque on index teeth, and dietary and oral hygiene habits by a questionnaire. Kappa statistics was used to test reliability of study instruments, χ2-test and logistic regression was employed for studying associations. Results: Caries free children for dmft1, dmft2 and dmft3 were 79.8%, 83.8% and 94.7% and caries experience was 0.49 (1.23), 0.4 (1.14) and 0.10 (0.53) respectively. Older age [(OR =2.722 (1.617-4.582) p=caries. Prolonged breastfeeding for more than 1 year and breastfeeding at night had no association with dental caries. Conclusion: The prevalence of dental caries was very low. Older age and frequent consumption of factory made sugary foods at age 1-2 years were associated with higher odds of developing dental caries. Prolonged breasfeeding and breastfeeding at night had no association with dental caries. Prevention of dental caries should be instituted as soon as primary teeth start erupting, especially through discouraging consumption of factory made sugary foods/snacks. PMID:28620634

    Background There are an increasing number of reports on time trends in child and adolescent psychological problems but none from low- and middle-income countries, and very few covering the preschool period. The aim was to investigate changes in preschool behavioral/emotional problems in two birth cohorts from a middle-income country born 11 years apart. Methods We analyzed data from the 1993 and 2004 Pelotas birth cohort studies from Brazil. A subsample of 4-year olds from the 1993 cohort (634) and all 4-year olds from the 2004 cohort (3750) were assessed for behavioral/emotional problems through maternal report using the Child Behavior Checklist (CBCL). Response rates in these two population-based cohorts were above 90%. Results We found a significant increase in CBCL total problems, internalizing and externalizing mean scores over the 11-year period. For 1993 and 2004 Pelotas cohorts, respectively, CBCL mean values (SE) total problems scores were 27.9 (0.8) and 34.7 (0.3); for internalizing scores, 5.7 (0.2) and 6.3 (0.1) and for externalizing scores, 12.4 (0.4) and 15.5 (0.1). After adjusting for confounding variables, the largest increase from 1993 to 2004 was identified in the aggressive behavior syndrome score (Cohen's d = .50), followed by the externalizing problem score (Cohen's d = .40) and CBCL total problem score (Cohen's d = .36), respectively. The rise in child psychological problems was more marked in children from families with fewer assets and with less educated mothers. Conclusions Our findings provide evidence for a substantial increase in preschool behavioral problems among children in Brazil over an 11-year period. PMID:24735354

    Does ovarian hyperstimulation, the in vitro procedure, or a combination of these two negatively influence blood pressure (BP) and anthropometrics of 4-year-old children born following IVF? Higher systolic blood pressure (SBP) percentiles were found in 4-year-old children born following conventional IVF with ovarian hyperstimulation compared with children born following IVF without ovarian hyperstimulation. Increasing evidence suggests that IVF, which has an increased incidence of preterm birth and low birthweight, is associated with higher BP and altered body fat distribution in offspring but the underlying mechanisms are largely unknown. We performed a prospective, assessor-blinded follow-up study in which 194 children were assessed. The attrition rate up until the 4-year-old assessment was 10%. We measured BP and anthropometrics of 4-year-old singletons born following conventional IVF with controlled ovarian hyperstimulation (COH-IVF, n = 63), or born following modified natural cycle IV (MNC-IVF, n = 52), or born to subfertile couples who conceived naturally (Sub-NC, n = 79). Both IVF and ICSI were performed. Primary outcome measures were the SBP percentiles and diastolic BP (DBP) percentiles. Anthropometric measures included triceps and subscapular skinfold thickness. Several multivariable regression analyses were applied in order to correct for subsets of confounders. The value 'B' is the unstandardized regression coefficient. SBP percentiles were significantly lower in the MNC-IVF group (mean 59, SD 24) than in the COH-IVF (mean 68, SD 22) and Sub-NC groups (mean 70, SD 16). The difference in SBP between COH-IVF and MNC-IVF remained significant after correction for current, early life and parental characteristics (B: 14.09; 95% confidence interval (CI): 5.39-22.79), whereas the difference between MNC-IVF and Sub-NC did not. DBP percentiles did not differ between groups. After correction for early life factors, subscapular skinfold thickness was thicker in the

    Full Text Available Congenital adrenal hyperplasia (CAH due to 21-hydroxylase deficiency results in excess androgen production which can lead to early epiphyseal fusion and short stature. Prader-Willi syndrome (PWS is a genetic disorder resulting from a defect on chromosome 15 due to paternal deletion, maternal uniparental disomy, or imprinting defect. Ninety percent of patients with PWS have short stature. In this article we report a patient with simple-virilizing CAH and PWS who was overtreated with glucocorticoids for CAH and not supplemented with growth hormone for PWS, resulting in a significantly short adult height.

    Intravascular papillary endothelial hyperplasia (IPEH), often referred to as Masson’s tumor, is a benign non-neoplastic vascular lesion of the skin and subcutaneous tissues. Although it is rare, knowledge of the existence of IPEH is important as it can mimic other benign and malignant tumors, most notably angiosarcoma. IPEH remains an incompletely understood entity; however, most consider it to be the result of reactive endothelial proliferation following thrombus formation within a vessel, vascular malformation, or adjacent to a vessel. In this article, we report a case of IPEH arising within an arteriovenous malformation of the radial artery and present accompanying multimodality imaging and pathology figures. We will also describe the clinical presentation, pathophysiology, histology, imaging features, and management of IPEH.

    Objective: To evaluate the metabolic level of different types of benign prostate hyperplasia (BPH) with MRS in Chinese adult. Methods: Ten BPH patients verified by biopsy were divided into two types: glandular BPH and stromal BPH. 3DMRS were performed on the central zone to measure the ratio of (Cho + Cre) /Cit. Results: The mean ratio of (Cho + Cre)/Cit in central zone of glandular BPH was 0.55 ± 0.32, whereas that of stromal BPH was 0.87 ± 0.34. Statistically significant difference was detected between the two types of BPH (t=8.18, P<0.05). Conclusion: The metabolic levels of prostate with BPH could be measured with MRS quantitatively, and metabolic difference could be detected between glandular BPH and stromal BPH. (authors)

    Full Text Available Benign prostatic hyperplasia (BPH is a histological diagnosis associated with unregulated proliferation of connective tissue, smooth muscle and glandular epithelium. BPH may compress the urethra and result in anatomic bladder outlet obstruction (BOO; BOO may present as lower urinary tract symptoms (LUTS, infections, retention and other adverse events. BPH and BOO have a significant impact on the health of older men and health-care costs. As the world population ages, the incidence and prevalence of BPH and LUTS have increased rapidly. Although non-modifiable risk factors - including age, genetics and geography - play significant roles in the etiology of BPH and BOO, recent data have revealed modifiable risk factors that present new opportunities for treatment and prevention, including sex steroid hormones, the metabolic syndrome and cardiovascular disease, obesity, diabetes, diet, physical activity and inflammation. We review the natural history, definitions and key risk factors of BPH and BOO in epidemiological studies.

    Full Text Available During preschool years, major developments occur in both executive function and theory of mind (ToM, and several studies have demonstrated a correlation between these processes. Research on the development of inhibitory control (IC has distinguished between more cognitive, cool aspects of self-control, measured by conflict tasks, that require inhibiting an habitual response to generate an arbitrary one, and hot, affective aspects, such as affective decision making, measured by delay tasks, that require inhibition of a prepotent response. The aim of this study was to investigate the relations between 3- and 4-year-olds’ performance on a task measuring false belief understanding, the most widely used index of ToM in preschoolers, and two tasks measuring cognitive versus affective aspects of IC. To this end, we tested 101 Italian preschool children in three tasks: (a the Unexpected Content False Belief task, (b the Conflict task (a simplified version of the Day-Night Stroop task, and (c the Delay task. Children’s receptive vocabulary was assessed by the Peabody Picture Vocabulary test. Children’s performance in the False Belief task was significantly related only to performance in the Conflict task, controlling for vocabulary and age. Importantly, children’s performance in the Conflict task did not significantly correlate with their performance in the Delay task, suggesting that these tasks measure different components of IC. The dissociation between the Conflict and the Delay task may indicate that monitoring and regulating a cool process (as flexible categorization may involve different abilities than monitoring and regulating a hot process (not touching an available and highly attractive stimulus. Moreover, our findings support the view that cool aspects of IC and ToM are interrelated, extending to an Italian sample of children previous findings on an association between self-control and ToM.

    Phenology monitoring has traditionally focused on the start of phenological phases and the start of the growing season, especially when it comes to species-specific observations on the ground. The patterns of and the mechanisms behind the end of particular phases and the growing season itself are less studied and poorly understood. With a changing climate, the need to understand and predict effects on the length as well as on the end of phenological phases increase in importance, e.g. in relation to estimations of carbon budgets and validation of remote sensing data. Furthermore, different species may be affected in different ways by changing conditions. In this 4-year-study, tens of thousands of pupils in ages from 6 to 19 years old were involved in observing autumn leaf development of common deciduous tree species. Their observations were made near schools all over Sweden (55-68°N). Observations were made weekly between late August and early November and followed an image-based observation protocol, classifying autumn leaf development into five levels, from a summer-green (level 0) to a 100% autumn-colored (level 4) canopy. As expected, there was a general (negative) correlation between latitude and the start of leaf senescence (level 2; 1/3 autumn-colored canopy), but the correlation differed largely among years and between species. There was a week correlation between latitude and duration of the leaf senescence period, defined as the period between 1/3 (level 2) and 100% (level 4) of autumn-colored canopy. A delayed onset of the leaf senescence affected the duration of the leaf senescence period more strongly; One (1) day later start was correlated with a 5-day shorter period. Different species had different length of their senescence period, with oak (mainly Quercus robur) and birches (Betula pendula and B. pubescence) having on average a 50% longer period than trembling aspen (Populus tremula) and Norway maple (Acer platanoides).

    Dental implants are a predictable treatment option for replacing missing teeth and have strong survival and success outcomes. However, previous research showed a wide array of potential risk factors that may have contributed to dental implant failures. The objectives of this study are to study if implant survival rates were affected by known risk factors and risk indicators that may have contributed to implant failures. The secondary outcome measures were whether the level of expertise of the periodontal residents affected success rates and how the rate of implant success at the Harvard School of Dental Medicine (HSDM) compared to published standards. A retrospective chart review of patients at the HSDM who had one of two types of rough-surface implants (group A or B) placed by periodontology residents from 2003 to 2006 was performed. Demographic, health, and implant data were collected and analyzed by multimodel analyses to determine failure rates and any factors that may have increased the likelihood of an implant failure. The study cohort included 341 dental implants. The odds ratio for an implant failure was most clearly elevated for diabetes (2.59 implant surface group B (7.84), and male groups (4.01). There was no significant difference regarding the resident experience. The success rate for HSDM periodontology residents was 96.48% during the 4-year study period. This study demonstrates that implant success rates at HSDM fell within accepted published standards, confirmed previously identified risk factors for a failure, and potentially suggested that other acknowledged risk factors could be controlled for. Furthermore, the level of experience of the periodontology resident did not have an impact on survival outcomes.

    Insomnia is a common complaint in the general population. Interest in the use of alternative treatments for insomnia is increasing exponentially and is fairly common in Taiwan. We undertook a survey to define the drug utilization patterns of Chinese herbal medicines (CM) for insomnia in Taiwan. The survey was conducted over a period of 4 years, from January 2003 to December 2006. Outpatients with primary insomnia and being treated with CM were studied. Core drug-use indicators were the number of CM items per prescription, the dosing frequency and duration of CM prescriptions, the most common prescribed CM herbs and CM formulae used. Six thousand eight hundred and sixty patients, using 37,046 CM herb items, were screened during the study period. The average CM items per prescription was 5.40. Most of prescriptions (95.23%) were prescribed for administration three times a day. The most often prescribed Chinese herbal products were Hong-Hwa (Carthamus tinctorius) and Jia-Wey-Shiau-Yau-San, which includes Angelica sinensis, Atractylodes macrocephala, Paeonia lactiflora, Bupleurum chinense, and Poria coco. This is the first extensive survey examining the drug utilization patterns of Chinese herbal medicines in the treatment of insomnia. Although the data were generated in Taiwan, the herbs and practices identified are likely to be widely generalizable wherever Chinese herbal remedies are used for insomnia. Multiple herbs and complex formulae were commonly used. The baseline data generated should be of use in informing subsequent studies, including those aimed at a thorough evaluation of the herbs' effectiveness.

    Home care for respiratory patients includes a complex array of services delivered in an uncontrolled setting. The role of a respiratory specialist inside the home healthcare team has been scarcely studied up to now. Our aims were to analyse the number and quality of episodic home visits performed by respiratory physicians to severe bedridden Chronic Respiratory Failure (CRF) patients, and also to evaluate the safety of tracheotomy tube substitutions at home. 231 home interventions (59.8/year) in 123 CRF patients (59 males; age 63 +/- 17 y, 24 on oxygen therapy, 35 under non invasive mechanical ventilation, 46 under invasive ventilation, 74 with tracheostomy) located 35 +/- 16 km far from referred hospital, were revised in a period of 4 years (2005-2008). Chronic Obstructive Pulmonary Disease (COPD) (31%) and amyotrophic lateral sclerosis (ALS) (28%) were the more frequent diagnoses. Interventions were: tracheotomy tube substitution (64%) presenting 22% of minor adverse events and 1.4% of major adverse events; change or new oxygen prescription (37%); nocturnal pulsed saturimetric trend prescription (24%); change in mechanical ventilation (MV) setting (4%); new MV adaptation (7%). After medical intervention, new home medical equipment devices (oxygen and MV) were prescribed in 36% of the cases while rehabilitative hospital admission and home respiratory physiotherapy prescription was proposed in 9% and 6% of the cases respectively. Patient/caregiver's satisfaction was reported on average 8.48 +/- 0.79 (1 = the worst; 10 = the higher). The local health care system (HCS) reimbursed 70 euros for each home intervention. Families saved 42 +/- 20 euros per visit for ambulance transportation. Home visits performed by a respiratory physician to bedridden patients with chronic respiratory failure: 1. include predominantly patients affected by COPD and ALS; 2. determine a very good satisfaction to patients/caregivers; 3. allow money saving to caregivers; 4. are predominantly

    Critical care patients often have several risk factors for pressure ulceration and implementing prevention interventions have been shown to decrease risk. We identified a high incidence of pressure ulcers in the four adult critical care units in our organization. Therefore, avoiding pressure ulceration was an important quality priority. We undertook a quality improvement programme aimed at reducing the incidence of pressure ulceration using an evidence-based bundle approach. A bundle of technical and non-technical interventions were implemented supported by clinical leadership on each unit. Important components were evidence appraisals; changes to mattresses; focussed risk assessment alongside mandating patients at very high risk to be repositioned two hourly; and staff training to increase awareness of how to prevent pressure ulcers. Pressure ulcer numbers, incidence and categories were collected continuously and monitored monthly by unit staff. Pressure ulcer rates reduced significantly from 8.08/100 patient admissions to 2.97/100 patient admissions, an overall relative rate reduction of 63% over 4 years. The greatest reduction was seen in the most severe category of pressure ulceration. The average estimated cost saving was £2.6 million (range £2.1-£3.1). A quality improvement programme including technical and non-technical interventions, data feedback to staff and clinical leadership was associated with a sustained reduction in the incidence of pressure ulceration in the critically ill. Strategies used in this programme may be transferable to other critical care units to bring more widespread patient benefit. © The Author 2017.

    Full Text Available Pain is one of the most common complaints in patients after experiencing a surgery. Surgery is a biphasic event against the human body that implies pain management. In post-surgery patients feel severe pain and 75% of patients have unpleasant experiences due to inadequate pain management.Based on the results of activity reports in Dr. Hi. Abdul Moeloek Public Hospital in Lampung Province in July-December 2016 obtained data operation BPH as many as 51 inhabitants. The objective of this research was to find out the effect of progressive relaxation to an intensity of pain for BPH (Benigna Prostate Hyperplasia post-surgery patient. This was a quasi-experiment research by using one group pretest and posttest design. 20 respondent samples were taken by using accidental sampling. Data were collected by using observation sheet and analyzed by using univariate and bivariate analyses with Wilcoxon sign test. The results showed that the mean value of pain before the progressive relaxation therapy equal to 5.20 with standard deviation 0.834. While the mean value of pain scale after it was 3.60 with standard deviation 0.681. Analysis with Wilcoxon sign test derived p-value 0.000 (ρ-value 0.000 < α 0.05, and the conclusion there was a significant effect the mean value of pain in the post-surgery patient’s BPH (Benigna Prostate Hyperplasia after progressive relaxation therapy. The researcher expects that the progressive relaxation therapy can be used by more operational methods.

    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.

    Full Text Available Background: Insulin-like growth factor (IGF, transforming growth factor-beta1 (TGF-β1, and vascular endothelial growth factor (VEGF are commonly studied growth factors, but little data are available on the immunohistochemical expression of these factors in parathyroid lesions. Materials and Methods: Tissue specimens from 36 patients with primary hyperparathyroidism (P-HPT (26 adenomas and 10 primary hyperplasias were examined. Normal parathyroid tissue adjacent to the adenoma or area of hyperplasia was used as control tissue. Preoperative laboratory testing [serum Ca and P, creatinine and parathormone levels (PTH] which led to the diagnosis of P-HPT had been performed, the size and weight of the parathyroid glands measured, and postoperative serum PTH levels determined. Paraffin-embedded parathyroid tissue specimens were stained with antibodies to IGF-1, VEGF, and TGF-β1 using standard immunohistochemical procedures. Results: IGF-1 immunoreactivity was seen in 50% of hyperplasia and in 46% of adenoma samples, but in 87% of normal parathyroid tissue in the vicinity of the adenomas (P = 0.005. TGF-β1 immunoreactivity was observed in 90% of hyperplasia, in 92% of adenoma samples, and in 95% of normal tissues around adenomas. VEGF immunoreactivity was observed in 70% of hyperplastic and 65% of adenomatous tissues, as well as in 54% of normal tissues in the vicinity of the adenoma. No significant differences in the expression of IGF-1, TGF-β1, and VEGF were observed between primary adenomas compared to hyperplasia samples (P > 0.05. Conclusions: Parathyroid tissue is clearly a site for production of IGF-1, TGF-β1, and VEGF. IGF-1 receptor activity was higher in normal parathyroid tissue compared to hyperplastic and adenomatous tissue.

  7. The link between benign prostatic hyperplasia and prostate cancer

    2013-01-01

    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.

    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.

    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.

    Hyperandrogenism in females usually results from ovarian or adrenal pathology. We present a case of virilizaton due to very rare bilateral ovarian diffuse interstitial proliferation of Leydig cells with no tumour or hilar cell hyperplasia identified. Interestingly, the case was further complicated by the finding of high levels of testosterone in one adrenal vein on selective venous sampling (SVS), resulting in an unnecessary unilateral adrenalectomy. Further sampling found high levels also in the ovarian veins, and the condition was finally cured by bilateral oophorectomy.

    2005-01-01

    The results of preoperative preparation were analysed in 59 patients with prostatic benign hyperplasia (PBH) subjected to TUR. Treatment outcomes were assessed by transrectal ultrasound (color Doppler mapping) in two groups of patients. Group 1 received combined therapy including transrectal laser radiation of the prostate, group 2--transrectal magnetotherapy. The analysis showed that laser radiation reduced insignificantly the size of the prostate and adenomatous node, improved microcirculation and circulation in the prostate. This resulted in relief of inflammation and reduction of the number of postoperative inflammatory complications. Transrectal magnetotherapy has a positive effect on vascularization and hemodynamics of the prostate, local immunity, contamination of the tissues with pathogenic flora.

    Aberrant regulation of airway epithelial cell numbers in airways leads to increased mucous secretions in chronic lung diseases such as chronic bronchitis. Because the Bcl-2 family of proteins is crucial for airway epithelial homeostasis, identifying the players that reduce cigarette smoke (CS)-induced mucous cell metaplasia can help to develop effective therapies. To identify the Bcl-2 family of proteins that play a role in reducing CS-induced mucous cell metaplasia. We screened for dysregulated expression of the Bcl-2 family members. We identified Bik to be significantly reduced in bronchial brushings of patients with chronic epithelial cell hyperplasia compared with nondiseased control subjects. Reduced Bik but increased MUC5AC mRNA levels were also detected when normal human airway epithelial cells (HAECs) were exposed to CS or when autopsy tissues from former smokers with and without chronic bronchitis were compared. Similarly, exposure of C57Bl/6 mice to CS resulted in increased numbers of epithelial and mucous cells per millimeter of basal lamina, along with reduced Bik but increased Muc5ac expression, and this change was sustained even when mice were allowed to recover in filtered air for 8 weeks. Restoring Bik expression significantly suppressed CS-induced mucous cell metaplasia in differentiated primary HAEC cultures and in airways of mice in vivo. Bik blocked nuclear translocation of phospho-ERK1/2 to induce apoptosis of HAECs. The conserved Leu61 within Bik and ERK1/2 activation were essential to induce cell death in hyperplastic mucous cells. These studies show that CS suppresses Bik expression to block airway epithelia cell death and thereby increases epithelial cell hyperplasia in chronic bronchitis.

    In the uterus, epithelial cell proliferation changes during the estrous cycle and pregnancy. Uncontrolled epithelial cell proliferation results in implantation failure and/or cancer development. Transforming growth factor-β (TGF-β) signaling is a fundamental regulator of diverse biological processes and is indispensable for multiple reproductive functions. However, the in vivo role of TGF-β signaling in uterine epithelial cells remains poorly defined. We have shown that in the uterus, conditional deletion of the Type 1 receptor for TGF-β (Tgfbr1) using anti-Müllerian hormone receptor type 2 (Amhr2) Cre leads to myometrial defects. Here, we describe enhanced epithelial cell proliferation by immunostaining of Ki67 in the uteri of these mice. The aberration culminated in endometrial hyperplasia in aged females. To exclude the potential influence of ovarian steroid hormones, the proliferative status of uterine epithelial cells was assessed following ovariectomy. Increased uterine epithelial cell proliferation was also revealed in ovariectomized Tgfbr1 Amhr2-Cre conditional knockout mice. We further demonstrated that transcript levels for fibroblast growth factor 10 (Fgf10) were markedly up-regulated in Tgfbr1 Amhr2-Cre conditional knockout uteri. Consistently, treatment of primary uterine stromal cells with TGF-β1 significantly reduced Fgf10 mRNA expression. Thus, our findings suggest a potential involvement of TGFBR1-mediated signaling in the regulation of uterine epithelial cell proliferation, and provide genetic evidence supporting the role of uterine epithelial cell proliferation in the pathogenesis of endometrial hyperplasia. © The Author 2014.

    Benign prostatic hyperplasia (BPH), a disease occurring frequently among elderly males, is a slow progressive enlargement of the fibromuscular and epithelial structures of the prostate gland. Dietary factors may influence the prostate and exert an influence on prostatic growth and disease. The current study was undertaken to investigate the protective effect of dietary flaxseed supplementation against testosterone-induced prostatic hyperplasia in male rats. Forty male Wistar rats were divided into 5 groups: (1) untreated control; (2) treatment with testosterone propionate (TP) to induce prostate enlargement; (3) TP-treated group fed a diet containing 5% milled flaxseed; (4) TP-treated group fed a diet containing 10% milled flaxseed; and (5) TP-treated group fed a diet containing 20 ppm finasteride. Treatment with TP significantly increased the absolute and relative weights of different prostatic lobes, serum testosterone (T), and testosterone/estradiol ratio, as well as prostatic vascular endothelial growth factor (VEGF) expression, RNA synthesis per cell, and epithelial cell proliferation, detected as Ki67 labeling. Histopathological examination did not reveal marked differences in acinar morphology in ventral prostate, whereas morphometric analysis showed significantly increased epithelial cell height. Co-administration of flaxseed or finasteride with TP significantly reduced prostatic VEFG, epithelial cell proliferation, and RNA/DNA ratio, along with a significant increase in serum T and testosterone/estradiol ratio compared with TP-only-treated rats. Our results indicate that flaxseed, similar to the 5α-reductase inhibitor finasteride, blocked TP-induced prostate enlargement in a rat model of BPH, likely through suppression of prostatic VEFG and cellular proliferation.

    Benign prostatic hyperplasia (BPH) is one of the major disorders of the urinary system in elderly men. Docosahexaenoic acid (DHA) is the main component of n-3 polyunsaturated fatty acids (n-3 PUFAs) and has nerve protective, anti-inflammatory and tumour-growth inhibitory effects. Here, the therapeutic potential of DHA in treating BPH was investigated. Seal oil effectively prevented the development of prostatic hyperplasia induced by oestradiol/testosterone in a rat model by suppressing the increase of the prostatic index (PI), reducing the thickness of the peri-glandular smooth muscle layer, inhibiting the proliferation of both prostate epithelial and stromal cells, and downregulating the expression of androgen receptor (AR) and oestrogen receptor α (ERα). An in vitro study showed that DHA inhibited the growth of the human prostate stromal cell line WPMY-1 and the epithelial cell line RWPE-1 in a dose- and time-dependent manner. In both cell lines, the DHA arrested the cell cycle in the G2/M phase. In addition, DHA also reduced the expression of ERα and AR in the WPMY-1 and RWPE-1 cells. These results indicate that DHA inhibits the multiplication of prostate stromal and epithelial cells through a mechanism that may involve cell cycle arrest and the downregulation of ERα and AR expression. - Highlights: • Seal oil prevents oestradiol/testosterone (E2/T)-induced BPH in castrated rats. • Seal oil downregulates the expression of oestrogen receptor α(ERα) and androgen receptor (AR) in rat BPH tissues. • DHA inhibits the growth of human prostate stromal and epithelial cells in vitro. • DHA arrests human prostate stromal and epithelial cells in the G2/M phase and downregulates the expression of cyclin B1. • DHA inhibits the expression of ERα and AR in human prostate stromal and epithelial cells.

    Full Text Available Hee Ju Cho, Tag Keun Yoo Department of Urology, Eulji Hospital, Eulji University School of Medicine, Seoul, KoreaAbstract: α1-Adrenergic receptor antagonists are commonly used to treat male lower urinary tract symptoms and benign prostatic hyperplasia (BPH. We performed a literature search using PubMed, Medline via Ovid, Embase, and the Cochrane Library databases to identify studies on the treatment of BPH by silodosin. Silodosin is a novel α1-adrenergic receptor antagonist whose affinity for the α1A-adrenergic receptor is greater than that for the α1B-adrenergic receptor. Therefore, silodosin does not increase the incidence of blood pressure-related side effects, which may result from the inhibition of the α1B-adrenergic receptor. Patients receiving silodosin at a daily dose of 8 mg showed a significant improvement in the International Prostate Symptom Score and maximum urinary flow rate compared with those receiving a placebo. Silodosin also improved both storage and voiding symptoms, indicating that silodosin is effective, even during early phases of BPH treatment. Follow-up extension studies performed in the United States, Europe, and Asia demonstrated its long-term safety and efficacy. In the European study, silodosin significantly reduced nocturia compared to the placebo. Although retrograde or abnormal ejaculation was the most commonly reported symptom in these studies, only a few patients discontinued treatment. The incidence of adverse cardiovascular events was also very low. Evidence showing solid efficacy and cardiovascular safety profiles of silodosin will provide a good solution for the treatment of lower urinary tract symptoms associated with BPH in an increasingly aging society.

    Full Text Available ABSTRACT Purpose The vast majority of urothelial carcinomas infiltrating the bladder are consistent with high-grade tumors that can be easily recognized as malignant in needle prostatic biopsies. In contrast, the histological changes of low-grade urothelial carcinomas in this kind of biopsy have not been studied. Materials and Methods We describe the clinicopathologic features of two patients with low-grade bladder carcinomas infiltrating the prostate. They reported dysuria and hematuria. Both had a slight elevation of the prostate specific antigen and induration of the prostatic lobes. Needle biopsies were performed. At endoscopy bladder tumors were found in both cases. Results Both biopsies showed nests of basophilic cells and cells with perinuclear clearing and slight atypia infiltrating acini and small prostatic ducts. The stroma exhibited extensive desmoplasia and chronic inflammation. The original diagnosis was basal cell hyperplasia and transitional metaplasia. The bladder tumors also showed low-grade urothelial carcinoma. In one case, the neoplasm infiltrated the lamina propria, and in another, the muscle layer. In both, a transurethral resection was performed for obstructive urinary symptoms. The neoplasms were positive for high molecular weight keratin (34BetaE12 and thrombomodulin. No metastases were found in either of the patients, and one of them has survived for five years. Conclusions The diagnosis of low-grade urothelial carcinoma in prostate needle biopsies is difficult and may simulate benign prostate lesions including basal cell hyperplasia and urothelial metaplasia. It is crucial to recognize low-grade urothelial carcinoma in needle biopsies because only an early diagnosis and aggressive treatment can improve the prognosis for these patients.

    To study the effect of metformin therapy in patients with polycystico varian syndrome having irregular heavy menstrualcycle and thickened endometrium (hyperplasia) on transvaginal ultrasound. Study Design: Quasi-experimental study. Place and Duration of Study: The study was conducted in Military Hospital Rawalpindi, department of gynae /obsunit-I from January 2009 -June 2010. Patients and Methods: A total of 100 patients in the age group of 40-47 years who reported to gynae OPD with irregular heavy menstrual cycles with or without clinical features of hyperandrogenism were selected and informed consent was taken. Transvaginal ultrasound (TVS) was performed on them by the same operator and those who had polycystic ovaries (enlarged ovaries with > 8-9 follicles peripherally enlarged) and endometrial thickness > 12 mm in the follicular phase of the cycle were selected. Total 100 patients were included in the study, but 10 patients were dropped out. Metforminwas started after explaining the purpose of the study initially in low dose (500-1000mg/day) and was adjusted to 1500 mg/day over next 4-6 weeks. Patients with abnormal liver or renal functions and those already taking hormonal therapy or on tamoxifen were excluded from the study. The endometrial thickness was assessed on monthly follow up visits and final findings were recorded and presented at the end of one year. Results: Of 90 patients, mean age of patients was 43.25 years (SD =1.91), mean pretreatment endo metrial thickness was 20.25Mm (SD=4.85) mean and post treatment endometrial thickness was 16.38 mm (SD=4.72). There was a significant reduction in endometrial thickness after treatment with metformin. Conclusion: Metformin therapy (1500 mg/day) significantly reduces endometrial thickness (hyperplasia) in patients with PCOS. (author)

    To determine the clinical presentation of congenital adrenal hyperplasia and short- term response to treatment. Background: Congenital adrenal hyperplasia (CAH) is a genetic disorder which usually presents with life threatening emergencies. Awareness of physicians regarding these presentations is an essential for early diagnosis and lifesaving treatment. In view of the prevalence of the condition as reported from tertiary care centers within the country and other parts of the globe, we had carried out a study in the paediatric department of Shaheed Mohtrama Benazir Bhutto Medical University Larkana. Material and Methods: The study was conducted over a period of one year from July 2012 to June 2013. All infants presenting with vomiting, dehydration, shock, failure to thrive and ambiguous genitalia were examined and investigated thoroughly. The diagnosis was based upon a raised level of serum 17 OHP in a child with suggestive clinical features. Results: A total of 40 children were diagnosed to have CAH during the study period. The major presenting features were vomiting in 13 (32.5%), ambiguous genitalia 17 (42.5%), vomiting and ambiguous genitalia 10 (25%), shock 5(12.5%) and failure to thrive in 13 (32.5%) of cases. All the patients were followed up after initiation of treatment and good response was observed to short-term treatment. Conclusion: This study highlights the importance of common clinical features like vomiting, unreasonable dehydration, shock and ambiguous genitalia being the presenting features of CAH and the effectiveness of replacement therapy in amending life threatening emergencies due to this condition.

    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

    Full Text Available Introduction: Children with congenital adrenal hyperplasia (CAH provide us an opportunity to study the clinical effects of androgen excess in humans. We studied the sequence of pubertal development in girls with congenital adrenal hyperplasia initiated on treatment at different ages, to assess the effects of androgen exposure on the Hypothalamic-Pituitary-Ovarian (HPO axis. Materials and Methods: Girls more than 18 years of age, with CAH, on follow-up at this hospital were the subjects for this study. Details of history, physical findings, laboratory evaluation, and medication were noted from their case records and verified from the patients and their / parents, in addition to assessment of their present health status. Result: We studied 24 patients of classical CAH (SW-2, SV-22, average age - 24.5 ± 6.6 years. All had varying degrees of genital ambiguity (Prader stage 3 (n = 13, Prader stage 2 (n = 10, Prader stage 1 (n = 1. Among them were13 girls, who were started on steroids after eight years of age. Girls who received treatment from infancy and early childhood had normal pubertal development (mean age at menarche 11.4 ± 1.7 years. Hirsutism was not a problem among them. Untreated children had progressive clitoral enlargement throughout childhood, developed pubic hair at around three to six years of age, and facial hair between nine and eleven years. Plasma testosterone ranged from 3 to 6 ng / ml prior to treatment. Six of the 13 untreated CAH girls had subtle breast development starting at ages 11 - 16 years and three had spontaneous infrequent vaginal bleeding starting at ages 11 - 17. Steroid supplementation initiated pubertal changes in older girls in two-to-six months′ time. Conclusion: There was a delay in HPO axis maturation (as evidenced by delayed pubertal development in the absence of treatment in girls with CAH. This could be corrected with steroid supplementation.

    Aim: The study was designed to evaluate the hemato-biochemical alterations, urinalysis along with histomorphological and histological changes of prostate glands in dogs affected with benign prostatic hyperplasia (BPH) in and around Bhubaneswar, Odisha, India. Materials and Methods: In toto, 445 dogs presented to the Teaching Veterinary Clinical Complex of the College of Veterinary Sciences and Animal Husbandry, one Government Veterinary Hospital and two pet clinics in and around Bhubaneswar screened for the presence of BPH. Most of the 57 dogs were 6 years and above as reported by the owners. Only 57 dogs found positive for BPH basing on the presence of typical clinical signs subjected for a detailed hemato-biochemical study. Most of the 57 dogs were 6 years and above as reported by the owners. Routine and microscopic urinalyses were done as per the routine procedure. Histomorphological evaluations of prostate glands were done through manual rectal palpation. Histological examinations of prostate tissue sections of two dead dogs were conducted with routine hematoxylin and eosin stain. Results: The study revealed about 12.8% (57/445) of dogs was suffering from BPH. Typical clinical signs - such as passing small thin tape-shaped feces, holding tail away from backward, tenesmus, and straining during urination and defecation - were seen in most of the cases. Urine samples of affected dogs were positive for glucose, occult blood, and protein. A significant decrease in lymphocytes and increase in eosinophil counts in dogs with BPH was recorded. Serum biochemical analysis showed a nonsignificant increase in creatinine and blood urea nitrogen with a significant decrease in total protein, albumin, globulin, A:G ratio. Histology of prostate glands collected during postmortem was characterized by fibrosis of prostate gland, and hyperplasia of the acinar epithelium. Conclusions: High rate of the prevalence of BPH in dogs poses an alarming condition which if diagnosed at an

    Benign prostatic hyperplasia (BPH) is one of the major disorders of the urinary system in elderly men. Docosahexaenoic acid (DHA) is the main component of n-3 polyunsaturated fatty acids (n-3 PUFAs) and has nerve protective, anti-inflammatory and tumour-growth inhibitory effects. Here, the therapeutic potential of DHA in treating BPH was investigated. Seal oil effectively prevented the development of prostatic hyperplasia induced by oestradiol/testosterone in a rat model by suppressing the increase of the prostatic index (PI), reducing the thickness of the peri-glandular smooth muscle layer, inhibiting the proliferation of both prostate epithelial and stromal cells, and downregulating the expression of androgen receptor (AR) and oestrogen receptor α (ERα). An in vitro study showed that DHA inhibited the growth of the human prostate stromal cell line WPMY-1 and the epithelial cell line RWPE-1 in a dose- and time-dependent manner. In both cell lines, the DHA arrested the cell cycle in the G2/M phase. In addition, DHA also reduced the expression of ERα and AR in the WPMY-1 and RWPE-1 cells. These results indicate that DHA inhibits the multiplication of prostate stromal and epithelial cells through a mechanism that may involve cell cycle arrest and the downregulation of ERα and AR expression. - Highlights: • Seal oil prevents oestradiol/testosterone (E2/T)-induced BPH in castrated rats. • Seal oil downregulates the expression of oestrogen receptor α(ERα) and androgen receptor (AR) in rat BPH tissues. • DHA inhibits the growth of human prostate stromal and epithelial cells in vitro. • DHA arrests human prostate stromal and epithelial cells in the G2/M phase and downregulates the expression of cyclin B1. • DHA inhibits the expression of ERα and AR in human prostate stromal and epithelial cells.

    Vitamin D is an essential prohormone in calcium and phosphorus homeostasis. Recent studies show a high frequency of insufficiency/deficiency of vitamin D in the general population worldwide. Our objective was to estimate the prevalence of circulating vitamin D [25(OH)D3] deficiency and insufficiency in children and examine the associated factors. A total of 283 children, participants in the cohort INMA-Asturias, were studied. The 25(OH)D3 concentrations were quantified by high performance liquid chromatography. The prevalence of deficiency [25(OH)D3<20 ng/ml] and insufficiency [20-29.9 ng/ml] of vitamin D was estimated. Distribution of 25(OH)D3 for month of extraction of specimen, ingestion, and other factors were analysed. The mean 25(OH)D3 was 20.1 ng/ml (range 2.7-49.8), with 8.8% ≥ 30 ng/ml, 38.5% from 20-20.9 ng/ml, and 52.7%<20 ng/ml. Seasonal variation was found, with lower values in winter. There was no relationship between plasma levels and intake of vitamin D (median 2.7μg/day, range 0.81-12.62), time outdoors (mean 3hours, range: 0:21-6:55), or BMI or gender, but there was one found with the mother's levels during gestation. There is a high prevalence of vitamin D deficiency/insufficiency in children at 4 years. Solar exposure might not be enough in our region. Healthy children should be encouraged to follow adequate outdoor activities with associated sun exposure. Due the deficit of intake in childhood, recommendations are needed about a varied diet with vitamin D-containing foods in this age group, especially during the winter, and assessing the need of vitamin D supplementation in children at risk.

    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.

    Claims are made for the validity of some self-report pain scales for 3- and 4-year-old children, but little is known about their ability to use such tools. This systematic review identified self-report pain intensity measures used with 3- and/or 4- year-old participants (3-4yo) and considered their reliability and validity within this age span. The search protocol identified research articles that included 3-4yo, reported use of any pain scale, and included self-reported pain intensity ratings. A total of 1,590 articles were screened and 617 articles met inclusion criteria. Of the included studies, 98% aggregated self-report data for 3-4yo with data for older children, leading to overestimates of the reliability and validity of self-report in the younger age group. In the 14 studies that provided nonaggregated data for 3-4yo, there was no evidence for 3-year-old and weak evidence for 4-year-old children being able to use published self-report pain intensity tools in a valid or reliable way. Preschool-age children have been reported to do better with fewer than the 6 response options offered on published faces scales. Simplified tools are being developed for young children; however, more research is needed before these are adopted. Some self-report pain scales have been promoted for use with 3- and 4-year-old children, but this is on the basis of studies that aggregated data for younger and older children, resulting in overestimates of reliability and validity for the preschool-age children. Scales with fewer response options show promise, at least for 4-year-old children. Copyright © 2017 American Pain Society. Published by Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Prostate cancer and benign prostatic hyperplasia are very common diseases in older American men, thus having a reliable treatment modality for both diseases is of great importance. The currently used treating options, mainly surgical ones, have numerous complications, which include the many side effects that accompany such procedures, besides the invasive nature of such techniques. Focused ultrasound is a relatively new treating modality that is showing promising results in treating prostate cancer and benign prostatic hyperplasia. Thus this technique is gaining more attention in the past decade as a non-invasive method to treat both diseases. Methods In this paper, the design, construction and evaluation of a 1.75 dimensional ultrasound phased array to be used for treating prostate cancer and benign prostatic hyperplasia is presented. With this array, the position of the focus can be controlled by changing the electrical power and phase to the individual elements for electronically focusing and steering in a three dimensional volume. The array was designed with a maximum steering angle of ± 13.5° in the transverse direction and a maximum depth of penetration of 11 cm, which allows the treatment of large prostates. The transducer piezoelectric ceramic, matching layers and cable impedance have been designed for maximum power transfer to tissue. Results To verify the capability of the transducer for focusing and steering, exposimetry was performed and the results correlated well with the calculated field. Ex vivo experiments using bovine tissue were performed with various lesion sizes and indicated the capability of the transducer to ablate tissue using short sonications. Conclusion A 1.75 dimensional array, that overcame the drawbacks associated with one-dimensional arrays, has been designed, built and successfully tested. Design issues, such as cable and ceramic capacitances, were taken into account when designing this

    Full Text Available The allocation of resources to a peer partner is a prosocial act that is of fundamental importance. Joint rhythmic movement, such as occurs during musical interaction, can induce positive social experiences, which may play a role in developing and enhancing young children’s prosocial skills. Here, we investigated whether joint rhythmic movement, free of musical context, increases 4-year-olds’ sharing and sense of fairness in a resource allocation task involving peers. We developed a precise procedure for administering joint synchronous experience, joint asynchronous experience, and a baseline control involving no treatment. Then we tested how participants allocated resources between self and peer. We found an increase in the generous allocation of resources to peers following both synchronous and asynchronous movement compared to no treatment. At a more theoretical level, this result is considered in relation to previous work testing other aspects of child prosociality, for example, peer cooperation, which can be distinguished from judgments of fairness in resource allocation tasks. We draw a conceptual distinction between two types of prosocial behavior: resource allocation (an other-directed individual behavior and cooperation (a goal-directed collaborative endeavor. Our results highlight how rhythmic interactions, which are prominent in joint musical engagements and synchronized activity, influence prosocial behavior between preschool peers.

  16. 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.

In children, hypophosphatemic rickets (HR happen malabsorption of phosphate and increasing of renal tubular loss.Case Presentation We present the case of a 4-year-old girl who had medical history of HR with failure to thrive (FTT. Child hospitalized several times due to osteomalacia and leg fractures. In physical examinations, there were obvious signs of rickets such as bow legs and hands, deviations of the wrist and chest pigeon. The results of blood tests showed low level of Phosphorus; but the level of calcium was normal. Radiography showed deformity of wrists and hands. ConclusionHR should be considered as one of the childhood disorders which impairs metabolism of bone mineralization and cause osteomalacia and bones fractures. If HR undiagnosed and remedies poor during childhood, in older ages would reveal automatic fractures and mineralization defects.

    Semantic memory, defined as our store of knowledge about the world, provides representational support for all of our higher order cognitive functions. As such, it is crucial that the contents of semantic memory remain accessible over time. Although memory for knowledge learned through direct observation has been previously investigated, we know very little about the retention of knowledge derived through integration of information acquired across separate learning episodes. The present research investigated cross-episode integration in 4-year-old children. Participants were presented with novel facts via distinct story episodes and tested for knowledge extension through cross-episode integration, as well as for retention of the information over a 1-week delay. In Experiment 1, children retained the self-derived knowledge over the delay, though performance was primarily evidenced in a forced-choice format. In Experiment 2, we sought to facilitate the accessibility and robustness of self-derived knowledge by providing a verbal reminder after the delay. The accessibility of self-derived knowledge increased, irrespective of whether participants successfully demonstrated knowledge of the integration facts during the first visit. The results suggest knowledge extended through integration remains accessible after delays, even in a population in which this learning process is less robust. The findings also demonstrate the facilitative effect of reminders on the accessibility and further extension of knowledge over extended time periods. PMID:26774259

    Full Text Available Abstract Introduction A child experiencing an event of threatening or catastrophic nature may experience considerable post-traumatic psychological distress. Dog bites present an important public health problem and are a frequent cause of physical trauma in children. Physicians who manage paediatric trauma may not be vigilant of the high risk of psychological stress in children exposed to a physical injury. Case presentation A 4-year-old white girl of Greek origin, with a dog-bite related trauma was admitted to the University Hospital of Crete, Greece, for surgical repair and intravenous antibiotic therapy due to extensive lesions. Exposure to the traumatic event triggered the onset of an unusual psychological response, selective mutism and acute post-traumatic stress disorder. Conclusion There is limited literature discussing the psychological effect of dog bites in children. Parents and physicians involved in pediatric physical trauma need to be more familiar with post-traumatic behavioral reactions. Awareness of the potential development of such reactions may result in early detection and effective management of children at risk.

    2013-01-01

    Aim: This article discusses the level 4 (year 1) diagnostic radiography student holistic experience of the Research-informed Teaching experience (RiTe) at the University of Salford, UK. The purpose of RiTe is to expose undergraduate radiography students to more formal research, as part of their normal teaching and learning experience. Method: A grounded theory approach was adopted and a focus group with eight level 4 students was used to explore and evaluate the student experience and perception of RiTe. Results: Open coding defined categories and sub-categories, with axial and selective coding used to interrogate and explore the relationships between the focus group data. A number of insights were gained into the student holistic experience of RiTe. The issue of leadership for level 4 students was also identified. Discussion: The focus group participants found RiTe to be an extremely positive learning experience. RiTe also facilitated their translation of learnt theory into clinical skills knowledge alongside their understanding of and desire to participate in more research as undergraduates. The article also highlights areas for future research.

    The aim of this study was to evaluate the effects of 4-year estroprogestagen therapy (EP) on the bone mineral density (BMD) of 16- to 17-year-old girls with functional hypothalamic amenorrhea (FHA, n = 78). Baseline values of hormonal parameters, bone fraction of alkaline phosphatase (BALP), and cross-linked n-telopeptide of type I collagen (Ntx) were taken along with BMD measurements. Follow-up measurements of laboratory parameters were performed after 6 months of EP treatment. BMD was measured on a yearly basis. Six-month treatment resulted in a marked increase in estradiol levels and a significant decrease in BALP and Ntx. The relative increase in BMD was highest after the second year of treatment. Based on the dynamics of BMD changes during the first year of treatment, we identified a subgroup with no or insignificant reactions to the treatment. It was characterized by significantly higher baseline BMD and markedly lower baseline Ntx compared to the patients who responded to 1-year therapy well or extremely well. Further follow-up proved, however, that this subgroup did not differ significantly in terms of the long-term prognosis for BMD normalization. In conclusion, this study showed that EP therapy is effective in the treatment of BMD disorders associated with FHA.

Results: usage of one of variants of “symmetric” approach determines specificities of motor qualities’ development: among boys with ambidexterity in motor asymmetry variant “first with passive hand, then with active one” and variant “first with active and then with passive hand” ensure improvement of all tested qualities (except flexibility and quickness. Boys with right orientation of manual motor asymmetry demonstrated improvement of all qualities (except coordination in ballistic movements for accuracy, fulfilled by right arm in the first variant. In the second variant all qualities (except already mentioned quickness are improved. Conclusions: with any orientation of manual motor asymmetry the necessary condition of high activity and successful child’s training is development of interaction between cerebral semi-spheres. Coordinated movements by left and right arms strengthen such interaction. That is why it is purposeful to consequently fulfill every movement by every arm and by two arms simultaneously.

    This study assesses the prevalence of caries and some background factors in 4-year-old children in the city of Umeå, northern Sweden, and compares this with data from earlier studies to reveal changes over time. Children from the catchment areas of three Public Dental Health Service clinics in Umeå (n = 224) born during the third quarter of 2008 were invited to undergo a clinical dental examination. Decayed surfaces (including both dentine and enamel, except for enamel lesions on buccal and lingual surfaces), missing and filled surfaces (dmfs) were recorded using the same methods and criteria as in a series of earlier studies performed between 1980-2007. Background data were collected in a case-history and a questionnaire. Results. The proportion of children with caries significantly decreased from 2007 (38%) to 2012 (22%) (p 0.05). An immigrant background was associated with a lower frequency of tooth brushing and a higher intake of ice cream, sweets and chocolate drinks (p < 0.05). Although the proportion of children with caries declined between 2007-2012, this decline was limited to non-immigrant children. Since 1980 the distribution of dmfs remained unchanged among children with caries. More research on interventions for changing oral health behaviours is needed, specifically for immigrant children.

    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.

    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.

    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.)

    This study aimed to quantitatively and qualitatively evaluate the effects of a flaxseed-based diet on the histoarchitecture of the prostate of normal Wistar rats and of rats with induced BPH. The study included four experimental groups of ten animals each: casein control group (CCG), who were fed a casein-based diet; flaxseed control group (FCG), who were fed a flaxseed-based diet; hyperplasia-induced casein group (HICG), who were fed a casein-based diet; and hyperplasia-induced flaxseed group (HIFG), who were fed a flaxseed-based diet. Hyperplasia was induced by the subcutaneous implantation of silicone pellets containing testosterone propionate. After 20 weeks, the rats were euthanized and their prostate fixed in buffered formalin. Tissue sections were stained with HE, picrosirius red and immunostained for nuclear antigen p63. Histomorphometric analysis evaluated the epithelial thickness, epithelial area, individual luminal area, and total area of prostatic alveoli. The mean epithelial thickness obtained for HIFG and HICG was 16.52 ± 1.65 and 20.58 ± 2.86 µm, respectively. The mean epithelial thickness in HICG was greater than that in the other groups tested. HIFG had a smaller epithelial thickness and lower percentage of papillary projections in the prostatic alveoli. No significant difference was observed between CCG and FCG. The total area and mean alveolar area showed no significant differences between the groups. The number of cells immunostained for p63 was not significantly different between the groups evaluated. These results suggest that flaxseed has a protective effect on the prostate epithelium in BPH-induced animals.

    This study was to investigate the role of complementary and alternative medicine in the prevention and treatment of benign prostatic hyperplasia. For this purpose, a randomized, double-blind, placebo-controlled trial was performed over 12 months on 47 benign prostatic hyperplasia patients with average age of 53.3 years and international prostate symptom score over 8. Subjects received either sweet potato starch (group A, placebo, 320 mg/day), pumpkin seed oil (group B, 320 mg/day), saw palmetto oil (group C, 320 mg/day) or pumpkin seed oil plus saw palmetto oil (group D, each 320 mg/day). International prostate symptom score, quality of life, serum prostate specific antigen, prostate volume and maximal urinary flow rate were measured. In groups B, C and D, the international prostate symptom score were reduced by 3 months. Quality of life score was improved after 6 months in group D, while those of groups B and C were improved after 3 months, compared to the baseline value. Serum prostate specific antigen was reduced only in group D after 3 months, but no difference was observed in prostate volume in all treatment groups. Maximal urinary flow rate were gradually improved in groups B and C, with statistical significance after 6 months in group B and after 12 months in group C. None of the parameters were significantly improved by combined treatment with pumpkin seed oil and saw palmetto oil. From these results, it is suggested that administrations of pumpkin seed oil and saw palmetto oil are clinically safe and may be effective as complementary and alternative medicine treatments for benign prostatic hyperplasia.

    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.

    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.).

    Full Text Available Abstract Background Rising rates of obesity and overweight is an increasing public health problem all over the world. Recent research has shown the importance of early life factors in the development of child overweight. However, to the best of our knowledge there are no studies investigating the potential synergistic effect of early life factors and presence of parental overweight on the development of child overweight. Methods The study was population-based and cross-sectional. The study population consisted of children who visited the Child Health Care (CHC centers in Malmö for their 4-year health check during 2003-2008 and whose parents answered a self-administered questionnaire (n = 9009 children. Results The results showed that having overweight/obese parents was strongly associated with the child being overweight or obese. Furthermore, there was an association between unfavorable early life factors (i.e., mother smoking during pregnancy, presence of secondhand tobacco smoke early in life, high birth weight and the development of child overweight/obesity at four years of age, while breastfeeding seemed to have a protective role. For example, maternal smoking during pregnancy was associated with an odds ratio (OR of 1.47 (95% CI: 1.22, 1.76 for overweight and 2.31 (95% CI: 1.68, 3.17 for obesity. The results further showed synergistic effects between parental overweight and exposure to unfavourable early life factors in the development of child overweight. Conclusions The present study shows the importance of early life factors in the development of child overweight and obesity, and thus puts focus on the importance of early targeted interventions.
