Oxidative Stress in Poultry and the Therapeutic Role of Herbal Medicine in Intestinal Health

The intensive broiler farming model has accelerated the development of the poultry farming industry. However, it has also inevitably brought about many stressors that lead to oxidative stress in the organism. The intestine is the leading site of nutrient digestion, absorption, and metabolism, as well as a secretory and immune organ. Oxidative stress in animal production can harm the intestine, potentially leading to significant losses for the farming industry. Under conditions of oxidative stress, many free radicals are produced in the animal’s body, attacking the intestinal mucosal tissues and destroying the barrier integrity of the intestinal tract, leading to disease. Recently, herbs have been shown to have a favorable safety profile and promising application in improving intestinal oxidative stress in poultry. Therefore, future in-depth studies on the specific mechanisms of herbs and their extracts for treating intestinal oxidative stress can provide a theoretical basis for the clinical application of herbs and new therapeutic options for intestinal oxidative stress injury during poultry farming. This review focuses on the causes and hazards of oxidative stress in the intestinal tract of poultry, and on herbs and their extracts with therapeutic potential, to provide a reference for developing and applying new antioxidants.

Field cycling imaging to characterise breast cancer at low and ultra-low magnetic fields below 0.2 T

BackgroundThis prospective feasibility study explores Field-Cycling Imaging (FCI), a new MRI technology that measures the longitudinal relaxation time across a range of low magnetic field strengths, providing additional information about the molecular properties of tissues. This study aims to assess the performance of FCI and investigate new quantitative biomarkers at low fields within the context of breast cancer.MethodsWe conducted a study involving 9 people living with breast cancer (10 tumours in total, mean age, 54 ± 10 years). FCI images were obtained at four magnetic field strengths (2.3 mT to 200 mT). FCI images were processed to generate T1 maps and 1/T1 dispersion profiles from regions of tumour, normal adipose tissue, and glandular tissue. The dispersion profiles were subsequently fitted using a power law model. Statistical analysis focused on comparing potential FCI biomarkers using a Mann-Whitney U or Wilcoxon signed rank test.ResultsWe show that low magnetic fields clearly differentiate tumours from adipose and glandular tissues without contrast agents, particularly at 22 mT (1/T1, median [IQR]: 6.8 [3.9–7.8] s−1 vs 9.1 [8.9–10.2] s−1 vs 8.1 [6.2–9.2] s−1, P < 0.01), where the tumour-to-background contrast ratio was highest (62%). Additionally, 1/T1 dispersion indicated a potential to discriminate invasive from non-invasive cancers (median [IQR]: 0.05 [0.03–0.09] vs 0.19 [0.09–0.26], P = 0.038).ConclusionsTo the best of our knowledge, we described the first application of in vivo FCI in breast cancer, demonstrating relevant biomarkers that could complement diagnosis of current imaging modalities, non-invasively and without contrast agents.

Computed tomography-based radiological gynecomastia in SBMA as an independent differential diagnostic biomarker: a retrospective study.

Spinal bulbar muscular atrophy (SBMA) and amyotrophic lateral sclerosis (ALS) are motor neuron disorders that demonstrate overlapping clinical features, especially in the early stage. Therefore, the aim of this study was to investigate the utility of chest tomography (CT) imaging in distinguishing between SBMA and ALS. This was a retrospective study reviewing CT images from patients with SBMA and sporadic ALS and those in the control group. The CT images were assessed to measure the diameter and morphology of glandular tissue associated with gynecomastia. We compared CT-measured gynecomastia between the SBMA, ALS, and control groups. Additionally, correlation analyses were performed between the quantitative measurements of gynecomastia obtained from CT scans and various clinical/laboratory parameter in the SBMA group. 15 chest CT images were collected from SBMA, 41 from ALS, and 29 from control group. No statistical differences were observed in BMI, functional scales, or age at the time of CT scans between the SBMA and ALS groups. Despite similar functional scales and age in both groups, the mean glandular tissue diameter of breast tissue observed in chest CT imaging differed significantly between SBMA, ALS, and controls: 32.22 ± 12.57mm, 15.91 ± 4.81mm, and 15.76 ± 7.26mm, respectively. This disparity allowed for the differentiation of SBMA from ALS and controls with statistical significance. Clinical gynecomastia was 80%, while radiological gynecomastia was 93.3% in SBMA. A significantly higher prevalence of diffuse glandular morphology pattern in SBMA (50%) was observed, contrasting with the predominance of nodular morphology in ALS and controls (9.1% and 20%). Correlative analysis between glandular tissue diameter and other clinical/laboratory parameters within the SBMA group showed no specific finding. CT-based radiological gynecomastia effectively differentiated SBMA from ALS. These findings support the usefulness of radiological gynecomastia as a potential differential diagnostic marker for SBMA, especially in the early stages.

The role of sodium-glucose cotransporter 2 (SGLT2) inhibitors in epicardial adipose tissue modulation: a meta-analysis

Abstract Introduction Sodium-glucose cotransporter 2 (SGLT2) inhibitors have emerged as a groundbreaking class of antidiabetic medications, renowned for their glucose-lowering effects and cardiovascular benefits. Recent studies have suggested that SGLT2 inhibitors may extend their influence beyond glycemic control to impact adipose tissue physiology, particularly within the epicardial adipose depot. Epicardial adipose tissue (EAT), an actively secretory organ surrounding the heart, has been implicated in the modulation of cardiovascular risk. Purpose This meta-analysis aims to systematically review and synthesize existing literature on the effects of SGLT2 inhibitors on epicardial adipose tissue. Methods We performed a literature search for studies assessing epicardial adipose tissue before and after treatment with a SGLT2 inhibitor compared to a control group. We excluded reviews, editorials, case reports/case series, and studies that did not use SGLT2 inhibitors or did not have a control group for comparison. The main outcome of interest was the change in EAT volume/thickness at follow-up. Effect sizes are presented as standardized mean difference (SMD) with their corresponding 95% confidence intervals (CIs) and were pooled based on a random-effects model. The leave-one-out sensitivity analysis was used for further validation of the findings. Publication bias was assessed by funnel plot inspection and egger’s regression test. Results The literature search yielded 49 results. After application of the exclusion criteria, a total of 6 studies were selected for data extraction and inclusion in the meta-analysis. Accordingly, we detected that treatment with an SGLT2 inhibitor was associated with decreased EAT volume/thickness (SMD -1.79, 95% CI -2.91 to -0.66, p&amp;lt;0.01). There was substantial between-study heterogeneity (I2: 94%, p&amp;lt;0.01). Results remained robust even after exclusion of any single study. Funnel plot inspection and egger’s regression test did not indicate the presence of publication bias. Conclusion This meta-analysis suggests that SGLT2 inhibitors use is associated with a reduction in EAT volume/thickness, posing as a potential mechanism of their beneficial effects in heart failure outcomes.Figure

Increased expression of CXCL10 and CCL3 salivary gland chemokines in primary Sjögren's syndrome detected and systematically quantified using novel RNAscope® in situ hybridisation.

Primary Sjogren's syndrome is a chronic inflammatory disease characterised by the destruction of exocrine glands. We have previously shown significantly upregulated levels of CXCL10 and CCL3 chemokines in saliva from Sjogren's syndrome patients. In this study, we examined the expression pattern and localisation of these chemokines at the site of inflammation in patients' minor salivary glands using novel RNAscope® in situ hybridisation. Minor salivary glands from 33 primary Sjogren's syndrome patients and 22 non-Sjogren's syndrome sicca controls were included. The biopsies were formalin- fixed, paraffin-embedded and histopathologically evaluated. The CXCL10 and CCL3 mRNA expression in the glandular tissue was investigated using reverse transcription quantitative real-time polymerase chain reaction followed by RNAscope® in situ hybridisation. The mRNA expression of CXCL10 was higher than CCL3 in all patients. Significantly elevated expression of CXCL10 and CCL3 was detected in patients that also expressed autoantibody positivity and a positive biopsy for mononuclear cell infiltrates when compared to controls. CXCL10 was localised as clusters within focal infiltrates as well as adjacent to acinar and ductal epithelium, while CCL3 was expressed as scattered single mRNA molecules in focal infiltrates and in acinar cells. Our findings suggest CXCL10 as a possible disease biomarker in primary Sjogren's syndrome due to its upregulated expression in both saliva and minor salivary glands of patients and the localisation in the tissue. This should be re-assessed in a larger primary Sjogren's syndrome patient cohort, followed by additional functional studies to further validate its potential as a disease biomarker.

A fetus with a mass in the oral cavity: a rare case of large oral immature teratoma

Abstract Introduction/Objective Oral teratoma is a rare congenital neoplastic lesion composed of variable amounts of all three germ cell layers, comprising 2-9% of all teratomas. Teratomas are classified into subtypes depending upon the presence of immature components. Sacrococcygeal and head and neck regions are the most common sites, with slight female predominance. Mortality increases if diagnosed in the fetal or neonatal period. Methods/Case Report We report a case of male fetus diagnosed radiologically as ultrasound at 20 weeks of gestation revealed abnormal facial characteristics. A huge lump protruding from face measuring 10.8 x 6.7 cm was observed. Grossly a grey-white, multilobulated lesion was seen with cystic spaces originating from midline soft palate. Histologically an immature teratoma comprising bone, skin adnexae, glandular tissue and immature neuroepithelial tissue was identified. The case was distinguished as immature teratoma of the oropharynx. Results (if a Case Study enter NA) NA Conclusion Prenatal diagnosis with modalities including ultrasound, MRI, alpha fetoprotein concentrations, fetoscopy and fetal karyotyping is possible in early pregnancy which can aid in risk stratification and planning therapeutic interventions. Delayed diagnosis and treatment increase the likelihood of malignant transformation. Intrapartum intubation and resection of the tumor at the time of the cesarean section has shown better outcomes. However, despite all efforts, survival rates are low.

The state of cancer care in Russia: pancreatic cancer (C25). Diagnosis, prevalence, quality of accounting, typical mortality. Part 1. (clinical and population-based research)

The study focuses on pancreatic cancer (C25), a malignant neoplasm arising from the ductal epithelium or glandular tissue of the pancreas, which accounts for 3% of the overall cancer incidence in Russia. The rates of incidence and mortality are rising, with the number of newly registered patients in Russia being lower than the number of recorded deaths, although the one-year mortality rate among patients is decreasing. The direct cause of pancreatic cancer (C25) remains unknown. Risk factors for developing this condition include genetics, smoking, alcohol abuse, a sedentary lifestyle, excessive meat consumption, and a lack of plant-based foods in the diet. Diseases associated with a high risk of this pathology include long-standing chronic pancreatitis, newly diagnosed type 2 diabetes in individuals aged 50-70, and cystic neoplasms of the pancreas. The aim of the study is to examine the patterns of incidence and mortality, the quality of patient registration, the characteristics of tumor localization, and the histological structure of pancreatic cancer (C25). The study will also track the nature of annual mortality among patients and explore the possibilities, methods, and techniques of modern diagnosis and treatment for these patients. The research confirmed the significant burden of pancreatic cancer (C25), primarily due to the late detection of this disease. The study provided sufficient material to analyze age-related risk factors, as well as the patterns of incidence and mortality in the population. It also examined and presented mortality rates among patients, including during the first year of observation.

Method for co-registration of high-resolution specimen PET-CT with histopathology to improve insight into radiotracer distributions

BackgroundAs the spatial resolution of positron emission tomography (PET) scanners improves, understanding of radiotracer distributions in tissues at high resolutions is important. Hence, we propose a method for co-registration of high-resolution ex vivo specimen PET images, combined with computed tomography (CT) images, and the corresponding specimen histopathology.MethodsWe applied our co-registration method to breast cancer (BCa) specimens of patients who were preoperatively injected with 0.8 MBq/kg [18\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$^{18}$$\\end{document}F]fluorodeoxyglucose ([18F]FDG). The method has two components. First, we used an image acquisition scheme that minimises and tracks tissue deformation: (1) We acquired sub-millimetre (micro)-PET-CT images of ±2 mm-thick lamellas of the fresh specimens, enclosed in tissue cassettes. (2) We acquired micro-CT images of the same lamellas after formalin fixation to visualise tissue deformation. (3) We obtained 1 hematoxylin and eosin (H&E) stained histopathology section per lamella of which we captured a digital whole slide image (WSI). Second, we developed an automatic co-registration algorithm to improve the alignment between the micro-PET-CT images and WSIs, guided by the micro-CT of the fixated lamellas. To estimate the spatial co-registration error, we calculated the distance between corresponding microcalcifications in the micro-CTs and WSIs. The co-registered images allowed to study standardised uptake values (SUVs) of different breast tissues, as identified on the WSIs by a pathologist.ResultsWe imaged 22 BCa specimens, 13 cases of invasive carcinoma of no special type (NST), 6 of invasive lobular carcinoma (ILC), and 3 of ductal carcinoma in situ (DCIS). While the cassette framework minimised tissue deformation, the best alignment between the micro-PET-CT images and WSIs was achieved after deformable co-registration. We found an overall average co-registration error of 0.74 ± 0.17 mm between the micro-PET images and WSIs. (Pre)malignant tissue (including NST, ILC, and DCIS) generally showed higher SUVs than healthy tissue (including healthy glandular, connective, and adipose tissue). As expected, inflamed tissue and skin also showed high uptake.ConclusionsWe developed a method to co-register micro-PET-CT images of surgical specimens and WSIs with an accuracy comparable to the spatial resolution of the micro-PET images. While currently, we only applied this method to BCa specimens, we believe this method is applicable to a wide range of specimens and radiotracers, providing insight into distributions of (new) radiotracers in human malignancies at a sub-millimetre resolution.

Myoepithelioma of the Hand: A Systematic Review

Myoepithelioma is an exceptionally rare tumor, primarily arising in glandular tissues but occasionally found in soft tissues, including the hand. Its occurrence in the hand is particularly uncommon, presenting unique clinical challenges due to the limited number of documented cases and the unusual location. We conducted a literature review in June 2024, with the aim to evaluate the current understanding of hand myoepithelioma, recent diagnostic advances, treatment options, and the diverse presentations of this neoplasm. Articles confirmed that patients present with a painless, slow-growing mass in the hand, often misdiagnosed as more common soft tissue tumors like lipomas or fibromas. Imaging, particularly MRI and ultrasound, aids in assessing the tumor, but definitive diagnosis relies on histopathology, including immunophenotyping. Managing spindle cell myoepithelioma in the hand requires a multidisciplinary approach, with surgical excision being the primary treatment. Achieving clear margins is critical yet challenging due to the hand’s complex anatomy. In some cases, adjuvant therapies such as radiation or chemotherapy may be necessary. The prognosis depends on factors like tumor size, location, and the success of surgical removal, with complete excision typically leading to a favorable outcome.

A Systems-Level Analysis of 2-[18F]FDG PET in Pigs Reveals Complex Skeletal Metabolism Networks in vivo which are altered with Osteomyelitis

Our understanding of complex tissue interactions at a systems level remains rudimentary, limiting our ability to dissect mechanisms underlying diseases and develop novel therapeutics. Skeletal research has focused on the pathogenicity of obesity and diabetes mellitus on the skeleton; however, it has been recently revealed that the skeleton is not merely an endocrine target but also a secretory organ, modulating systemic energy homeostasis1,2. We recently discovered that different bones within the murine skeleton have a unique glucose metabolism and form a complex metabolic network3. Thus, we hypothesised that different bones within the porcine skeleton would have unique molecular signatures and form a distinct metabolic network, and these networks would be altered by osteomyelitis, an inflammatory condition of the bone. Five healthy mini and three Danish Landrace-Yorkshire pigs (inoculated with S. aureus to induce osteomyelitis) underwent static 2-[18F]FDG PET/CT and were analysed to measure bone and bone marrow adipose tissue (BMAT) glucose metabolism. Analyze was used for image analysis and processing. Bone and bone marrow volumes of interest were segmented in CT images using Hounsfield Unit (HU) &gt; 300 (bone) and HU -200 to 115 (BMAT; Fig1). PET images were used to extract average standard uptake values. Network analysis was performed using Graphia. Osteomyelitis pigs had a lower bone density and increased BMAT volume compared to healthy controls. There was an increased incorporation of 2-[18F]FDG into the bone and BMAT of osteomyelitis pigs. Similar to what has previously been observed in the mouse3 and human4, there was an increased incorporation of 2-[18F]FDG in the axial skeleton compared to the appendicular skeleton. Network analysis indicated a shift in bone metabolic profiles between healthy and osteomyelitis pigs. Please click on the 'PDF' for the full abstract!

Mini Review: Challenges and Promising Advances in Hydrogel‐Based Scaffolds for Breast Tissue Regeneration

ABSTRACTThe loss of breast tissue is a problem that plagues many women. Total mastectomy procedures after breast cancer or extensive tissue loss by accident generate permanent aesthetic‐functional lesions that are correlated with the loss of breastfeeding capacity, loss of self‐esteem, anxiety, depression, reduced sexual attraction, hopelessness, and often, suicide. Although current clinical practices try to restore aesthetics, functional improvements are not readily resolved by these maneuvers. Those who undergo such procedures often end up with permanent aesthetic and functional injuries. The difficulty in regenerating breast tissue stems from its high structural complexity. In cases of extensive loss of breast tissue, the use of regeneration strategies becomes necessary for proper healing and tissue reconstruction. In this context, the use of regeneration scaffolds may open new possibilities for the regeneration of various body tissues, especially breast tissue, enabling the adequate healing of large injuries in different tissues. Hydrogels are examples of highly versatile materials for this application, given the range of methodologies for their preparation and composition components. The results of various studies indicate that the application of hydrogel‐based scaffolds for breast regeneration is highly promising. Among the materials and systems most applied for this purpose, biodegradable polymers stand out due to their high biocompatibility and the ability for spontaneous removal from the organism. In this sector, systems obtained through 3D printing also stand out due to the increased predictability of geometry and pore distribution. However, it is noteworthy that the evaluated regeneration systems are primarily focused on regenerating adipose tissue, with no specific systems for the epithelial regeneration of the breasts or the areas of glandular tissue. These areas represent sectors that still need further exploration.

Ovarian and Uterine Morphology in Minipuberty: Associations with Reproductive Hormones. A COPANA Study of 302 girls.

Female minipuberty is characterized by complex dynamics of circulating reproductive hormones, while the relationship between ovarian and uterine morphology and reproductive hormones remains to be elucidated. To investigate the association between reproductive hormones and ovarian as well as uterine morphology by transabdominal ultrasound (TAUS) at minipuberty. Secondary analysis from The Copenhagen Analgesic Study (COPANA) (ClinicalTrials.gov NCT04369222). Healthy infant girls (n=302, age 3.4 months (0.4) mean (±SD): mamma tissue diameter (mm), n=300. TAUS: uterine volume (n=230), endometrial thickness (n=255), ovarian volume, antral follicle count (total/2-4mm/≥5mm) (n=203).Blood samples (n=269/302=89%): AMH, FSH, LH, inhibin B (immunoassays), progesterone (PROG), androstenedione (Adione), testosterone (T), estrone (E1), estradiol (E2) (LC/MS-MS).Statistics: Pearson/Spearman´s correlation coefficient (parametric/non-parametric data). Total follicle count correlated positively with ovarian volume (r= 0.606, p<0.001), AMH (r=0.378, p<0.001), inhibin B (r=0.251, p<0.001), and negatively with FSH concentrations (r=-0.327, p<0.001). Larger follicles (≥5mm) correlated positively with AMH (r=0.264, p<0.001), inhibin B (0.230, p=0.002), E1 (r=0.209, p=0.004), E2 (r=0.269, p<0.001), PROG (r=0.160, p=0.031) and T (r=0.210, p=0.004) and negatively with FSH (r=-0.183, p=0.015). Circulating E1 and E2 levels correlated with the size of estrogen-responsive tissue sizes: E2 vs. uterine volume (r=0.134, p=0.054), E2 vs. endometrial thickness (r=0.155, p=0.020), E1 and E2 vs. mammary tissue diameter (r=0.213 and r=0.198, respectively, both p < 0.001). Correlations between reproductive hormones and the number of antral follicles suggest that negative feedback in the female HPG axis is established during minipuberty, with ovarian activity promoting uterine and glandular breast tissue growth We provide normative data of infant ovarian- and uterine morphology directly implementable to a clinical setting.

Observations on the reproductive morphology of the female short-beaked echidna, Tachyglossus aculeatus.

Although monotremes diverged from the therian mammal lineage approximately 187 million years ago, they retain various plesiomorphic and/or reptilian-like anatomical and physiological characteristics. This study examined the morphology of juvenile and adult female reproductive tracts across various stages of the presumptive oestrous cycle, collected opportunistically from cadaver specimens submitted to wildlife hospitals during the breeding season. In adult females, ovaries had a convoluted cortex with follicles protruding from the ovarian surface. While protruding antral follicles were absent from the ovaries of juvenile echidnas, histological analysis identified early developing primordial and primary follicles embedded into the ovarian cortex. The infundibulum epithelial cells of the oviducts were secretory during the follicular phase but not at other stages, the ampulla region was secretory at all stages and is likely responsible for the mucoid layer deposited around the zona pellucida, and the isthmus region of the oviduct appeared to be responsible for initial deposition of the shell coat, as in marsupials. Female echidnas have two separate uteri, which never merge and enter separately into the urogenital sinus (UGS). This study confirmed that both uteri are functional and increase in glandular activity during the luteal phase. In the juvenile uteri, the endometrium was immature with minimal, small uterine glands. A muscular cervical region at the caudal extremity of each uterus, just before the cranial region of the UGS was defined by the absence of glandular tissue in all female echidnas, including the juveniles. There was no evidence of a definitive vaginal region. A clitoris was also detected that possessed a less developed but similar structural (homologous) anatomy to the male penis; urethral ducts while present did not appear to be patent.

Myokines May Be the Answer to the Beneficial Immunomodulation of Tailored Exercise-A Narrative Review.

Exercise can regulate the immune function, activate the activity of immune cells, and promote the health of the organism, but the mechanism is not clear. Skeletal muscle is a secretory organ that secretes bioactive substances known as myokines. Exercise promotes skeletal muscle contraction and the expression of myokines including irisin, IL-6, BDNF, etc. Here, we review nine myokines that are regulated by exercise. These myokines have been shown to be associated with immune responses and to regulate the proliferation, differentiation, and maturation of immune cells and enhance their function, thereby serving to improve the health of the organism. The aim of this article is to review the effects of myokines on intrinsic and adaptive immunity and the important role that exercise plays in them. It provides a theoretical basis for exercise to promote health and provides a potential mechanism for the correlation between muscle factor expression and immunity, as well as the involvement of exercise in body immunity. It also provides the possibility to find a suitable exercise training program for immune system diseases.

Detection of invasive ductal carcinoma by electrical impedance spectroscopy implementing gaussian relaxation-time distribution (EIS-GRTD)

Breast cancer detection and differentiation of breast tissues are critical for accurate diagnosis and treatment planning. This study addresses the challenge of distinguishing between invasive ductal carcinoma (IDC), normal glandular breast tissues (nGBT), and adipose tissue using electrical impedance spectroscopy combined with Gaussian relaxation-time distribution (EIS-GRTD). The primary objective is to investigate the relaxation-time characteristics of these tissues and their potential to differentiate between normal and abnormal breast tissues. We applied a single-point EIS-GRTD measurement to ten mastectomy specimens across a frequency range f = 4 Hz to 5 MHz. The method calculates the differential ratio of the relaxation-time distribution function Δγ between IDC and nGBT, which is denoted by ΔγIDC−nGBT, and Δγ between IDC and adipose tissues, which is denoted by ΔγIDC−adipose. As a result, the differential ratio of Δγ between IDC and nGBT ΔγIDC−nGBT is 0.36, and between IDC and adipose ΔγIDC−adipose is 0.27, which included in the α -dispersion at τpeak1=0.033±0.001s. In all specimens, the relaxation-time distribution function γ of IDC γIDC is higher, and there is no intersection with γ of nGBT γnGBT and adipose γadipose. The difference in γ suggests potential variations in relaxation properties at the molecular or structural level within each breast tissue that contribute to the overall relaxation response. The average mean percentage error δ for IDC, nGBT, and adipose tissues are 5.90%, 6.33%, and 8.07%, respectively, demonstrating the model’s accuracy and reliability. This study provides novel insights into the use of relaxation-time characteristic for differentiating breast tissue types, offering potential advancements in diagnosis methods. Future research will focus on correlating EIS-GRTD finding with pathological results from the same test sites to further validate the method’s efficacy.

Comparison of the Female Sexual Function Index, Beck Depression Inventory, and Patient Satisfaction Scale in Patients Undergoing Total Abdominal Hysterectomy and Single-Port Laparoscopic Hysterectomy for Benign Conditions

Aim: The uterus is widely accepted as a sexual organ, children-making body, secretory organ, youth, charm, or power supply by women. By hysterectomy, psychosocial problems such as fear of losing sexual identity occur, and depression may arise as a result of this. In this study, we investigated the effects of surgery on female sexual function and psychosocial situation according to the methods of Total Abdominal Hysterectomy (TAH) and Single Port Laparoscopic Hysterectomy (SPLH). Method: This prospective surgical study included 60 patients, including 30 SPLH and 30 TAH patients with benign reasons. The demographic data of patients, Female Sexual Function Inventory (FSFI) score, Beck Depression Questionnaire Scale, and Patient Evaluation Measurement (PEM) results were all assessed according to TAH and SPLH methods. Results: In the FSFI questionnaire, significant differences were found between SPLH and TAH groups for all "desire frequency," "desire level," "stimulation frequency," "stimulation level," and "stimulation trust" subquestions (p=0.004, p=0.0001, p=0.003, p=0.011 and p=0.011, respectively). In the Beck depression questionnaire, the TAH score (4.4±3.25) was significantly higher than the SPLH score (2.77±2.97) (p:0.047). TAH had 7.97±3.6 points, and SPLH had 3.73±1.1 points regarding treatment results (p:0.00017). Similarly, TAH had 14±4.4 points, while SPLH had 6.1±1.3 points regarding the functionality of hysterectomy (p

Effective minimally invasive strategy for mixed-type gynecomastia using vacuum-assisted mastectomy and power-assisted liposuction

IntroductionMixed-type gynecomastia is a benign male breast condition characterized by the proliferation of glandular and adipose tissues. Conventional open surgery has been the main approach for treating gynecomastia. However, this method has been associated with complications, including breast deformity, noticeable scar, nipple necrosis, and hypoesthesia. In contrast, Vacuum-assisted biopsy systems and liposuction have demonstrated significant advantages in minimal invasive breast surgery. AimsOur study aimed to investigate the effectiveness of combining vacuum-assisted mastectomy with power assistant liposuction (VAM+PAL) for patients with mixed-type gynecomastia compared to conventional open surgery. MethodsSixty patients with mixed-type gynecomastia, treated between January 2019 and June 2023, were included in this study. VAM+PAL was performed on 30 patients (59 breasts), while open excision with peri-areola approach was performed on another 30 patients (59 breasts). The efficacy, complications, outcomes, scar cosmesis, and patient satisfactions were assessed. ResultsCompared to open excision for gynecomastia, the VAM+PAL group demonstrated a substantial reduction in incision size (4.47±1.21cm vs. 0.97±0.74cm, p<0.001) and lower scores of Vancouver scar scale (3.23±2.27 vs. 1.10±1.47, p<0.001). No drainage tubes were required for postoperative hematoma/seroma prevention. The patients in the VAM+PAL group had a significantly lower complication rate (18.64% vs. 3.39%, p=0.008), particularly in bruise and hypoesthesia. All VAM+PAL patients reported superior satisfaction with the outcomes in breasts and nipples. ConclusionThe combination of vacuum-assisted mastectomy and power assistant liposuction can be used as an efficient minimally invasive method to treat mixed-type gynecomastia with acceptable complications, superior scar cosmesis, and satisfying outcomes.

A Unique Case of Unilateral Pseudogynecomastia.

Gynecomastia is a common condition characterized by the benign enlargement of male breast tissue, often resulting from hormonal imbalances. A rare variant, unilateral pseudogynecomastia, involves enlargement due to adipose tissue accumulation without glandular proliferation and can be associated with occupational factors. We report the case of a 45-year-old male mechanic presenting with unilateral enlargement of the left breast. The patient reported daily microtrauma on his left axilla and chest wall. The clinical evaluation and imaging revealed lipomatosis with pronounced fibrous tissue and no glandular tissue involvement. The hormonal assays were within the normal limits. The patient underwent surgical excision of excess adipose tissue using the Kornstein technique, preserving the nipple-areola complex. The histopathological examination confirmed the absence of malignancy. The postoperative recovery was uneventful, and the follow-up examination at 12 months demonstrated a symmetrical breast appearance with no recurrence. This case underscores the importance of differentiating pseudogynecomastia from true gynecomastia and recognizing potential occupational risks. Surgical management using techniques that preserve the nipple-areola complex can achieve excellent cosmetic outcomes.

Comparative Assessment of the Influence of Embolizing Agents on the Adrenal Parenchyma.

A comparative analysis of morphological and functional changes in the adrenal glands after embolization of supplying arteries with Lifepearl microspheres (100±25 μm; Terumo) and with a solution of polidocanol (Aethoxysklerol, Kreussler Pharma) was performed in male Vietnamese Lop-Bellied pigs (n=20). The introduction of the microspheres into the arterial bed did not affect the adrenal parenchyma. However, the injection of the liquid sclerosing agent caused foci of productive inflammation leading to the formation of sclerotic tissue and reduction of the volume of glandular tissue. Administration of the sclerosant was accompanied by arterial hypotension, an indirect indication of a decrease in vasoactive hormone production by the adrenal cortex. These findings suggest that polidocanol can be used as an embolization agent for hyperplastic diseases of the adrenal cortex.

Comparison of the Preoperative MRI Evaluation of Glandular Tissue in Subcutaneous Mastectomy and its Influence on the Implant Volume.

This study examined the influence of preoperative MRI on the choice of implant volume in patients undergoing subcutaneous mastectomy with immediate breast reconstruction. It was postulated that preoperative MRI scans can adequately estimate glandular tissue, which in turn correlates with implant size. Preoperative and postoperative MRI scans were used in oncological and prophylactical subcutaneous mastectomy scenarios in 67 cases at the Department of Gynaecology, Breast Cancer Center, University of Cologne, Germany. The preoperative MRI was used to estimate the resected tissue and the postoperative MRI was used to scan for residual glandular tissue. In addition, a correlation found by Malter et al. in 2021 was evaluated with the available data. Preoperative MRIs result in an adequate estimation of resected tissue. This in turn correlates with implant volume. The correlation by Malter et al. also holds when estimating implant volume. The likelihood of residual gland was low if the preoperatively estimate volume was removed. Our results indicate that the use of preoperative and postoperative MRI scans for subcutaneous mastectomies is advantageous. We suggest a routine estimation of glandular tissue, especially for small breasts.
