This case summarizes the management of a patient who presented for counseling 2 weeks after a stillbirth at 34 weeks’ gestation. Her pregnancy was uncomplicated until she developed prelabor rupture of membranes, leading to fetal demise. Placental pathology revealed findings suggestive of high-grade fetal vascular malperfusion, maternal vascular malperfusion, and severe ascending intrauterine infection. The most common placental abnormalities and their causes and associations are discussed as well as recommendations for further testing and future pregnancy management. Understanding placental histology following stillbirth allows for better support and preparation for future pregnancies.
This study investigates the seasonal and regional distribution of paediatric laryngomalacia admissions in the United States, hypothesizing higher admission rates in winter and colder regions due to reduced sunlight exposure affecting vitamin D levels.
Methods
We analyzed data from the 2016 Kids’ Inpatient Database (KID), focusing on children under three years old. Laryngomalacia cases were identified using International Classification of Diseases and Related Health Problems 10th Revision (ICD-10) code Q31.5. Seasonal and regional differences in admission rates were assessed using Pearson’s chi-squared test, with a significance level of p less than 0.05.
Results
Of 4,512,196 estimated national admissions, 11,638 were due to laryngomalacia. Admissions increased by 10.0 per cent in winter and decreased by 10.9 per cent in summer (p < 0.005). Regionally, admissions were higher in the Midwest/Central (18.6 per cent) and Northeast (9.3 per cent) and lower in the South (7.4 per cent) and West (11.1 per cent) (p < 0.005).
Conclusion
Laryngomalacia admissions are significantly influenced by seasonal and regional factors, likely related to environmental conditions affecting vitamin D synthesis.
Prior to the No Surprises Act (NSA), numerous states passed laws protecting patients from surprise medical bills from out-of-network (OON) hospital-based physicians supporting elective treatment in in-network hospitals. Even in non-emergency situations, patients have little ability to choose physicians such as anaesthesiologists, pathologists or radiologists. Using a comprehensive, multi-payer claims database, we estimated the effect of these laws on hospital-based physician reimbursement, charges, network participation and potential surprise billing episodes. Overall, the state laws were associated with a reduction in anaesthesiology prices and charges, but an increase in pathology and radiology prices. The price effects for each state exhibit substantial heterogeneity. California and New Jersey experienced increases in network participation by anaesthesiologists and pathologists and reductions in potential surprise billing episodes, but, overall, we find little evidence of changes in network participation across all of the states implementing surprise billing laws. Our results suggest that the effects of the NSA may vary across states.
The aim of this study was to evaluate the rate of dysplasia and carcinoma-ex-papillomatosis in patients with recurrent respiratory papillomatosis and assess for any risk factors.
Methods
A 15-year retrospective observational cohort study was performed from a single centre. Data on patient demographics, treatment history and pathology results were extracted from clinical records.
Results
Of the 123 patients identified, nine had juvenile-onset recurrent respiratory papillomatosis and 114 had adult-onset recurrent respiratory papillomatosis. Thirteen (11 per cent) of patients with adult-onset recurrent respiratory papillomatosis had dysplasia, and one patient progressed to carcinoma-ex-papillomatosis. Patients with evidence of dysplasia had an average older age of disease onset compared to those without dysplasia (49 years vs 39 years, p = 0.03).
Conclusion
An older age of recurrent respiratory papillomatosis onset was the only risk factor for dysplasia. Gender, tobacco use, subglottic or tracheal involvement, number of surgeries and cidofovir were not prognostic factors in this series.
Head and neck cancer has a 5 per cent incidence of synchronous primary cancer. Synchronous primary cancers are commonly detected with imaging and flexible nasoendoscopy. Routine panendoscopy is still being used to screen for synchronous primary cancers. The aim was to establish the method of detection of synchronous primary cancer.
Methods
A retrospective cohort study of newly diagnosed head and neck cancer patients with a synchronous primary cancer, presented at the West of Scotland Head and Neck Multidisciplinary Team from December 2020 to August 2022. This study is Level 3 evidence.
Results
A total of 2325 patients were presented to the Multi-Disciplinary Team with head and neck cancer and 54 (2.3 per cent) had SPC; 63.8 per cent (30) of patients had a panendoscopy. All patients with comprehensive out-patient assessment had their synchronous primary cancer detected on examination or imaging, without the need for panendoscopy.
Conclusion
Panendoscopy did not detect any new synchronous primary cancer in patients assessed with flexible nasoendoscopy and imaging. With modern high-resolution imaging and fibreoptics, panendoscopy does not play a role in the detection of synchronous primary cancers.
This chapter provides an introduction to dementia and mild cognitive impairment (MCI). It covers the incidence and prevalence of the most common forms of dementia, and explains the underlying causes in terms of different types of proteinopathy. Risk factors for development of dementia are reviewed, along with protective factors. The role of age is also considered as different subtypes of dementia peak during different age ranges. The contribution of genetics and epigenetics is reviewed, along with the importance of blood supply, sleep, and inflammation. The theory of cognitive and neuronal reserve is introduced as one of the factors which can predict which people are more or less likely to develop dementia and MCI. Connectomics and the arrangement of the brain into circuits is covered, along with developments in neuro-imaging.
This chapter examines the origins and legacy of sexology – the scientific study of sexuality – in the modern world. First consolidated into a coherent programme in the late nineteenth century, sexology has its roots in the re-organization of knowledge about nature in the frameworks of taxonomy, evolutionism, and race. A pervasive preoccupation with heredity gave rise to powerful eugenics movements around the world. The interest in controlling variability and unlocking the secrets of the soul generated parallel developments in biomedicine, especially psychoanalysis and endocrinology. Sex experts worldwide converged in diagnosing cultural signs of homosexuality for the purpose of national modernization. As the centre of gravity in sexual science began to shift from Europe to North America, researchers gave growing support to the sex/gender distinction and redefined the meanings of normality. In the waning days of hereditarian theories, the rise of cultural anthropology coupled with a renewed scientific investment of colonial powers to reverse hierarchical templates of sexual practices and norms emanating from the metropoles. A public health crisis (HIV/AIDS), social movements (gender and sexual minority rights), and the systematization of research protocols (bioethics) shaped a comeback of biological sexology in the closing decades of the twentieth century.
Abundant moments of indecision and delay shape George Eliot’s last novel Daniel Deronda (1876), which treats uncertainty as a recursive movement between interior and exterior, potentiality and activity. This chapter shows how Eliot explores action’s convoluted antecedents, drawing on intellectual trends in mid-century comparative method and physiological psychology, especially the latter’s portrait of embodied willing and pathologies of volition. These contexts frame a reading of the novel’s twin stances of practical experience and intellectual reflection: hesitation, the bewildering experience of having a “will which is and yet is not yet,” and its rational cousin, comparison, “our precious guide.” Formal fluctuations and portrayals of mental caprice would seem at cross-purposes with Eliot’s narrative control and moral coherence. Yet in discovering a “kinship” between certainty and doubt, she reinvigorates her novelistic ethics and recasts sympathy as guaranteed by “closer comparison between the knowledge which we call rational & the experience which we call emotional.” Her characters set store by irresolute stances of hesitation and comparison, and predictive affects like trust and hope.
Factors that are potentially important in the pulmonary pathogenesis of asbestos and other mineral particles are: 1) morphology, 2) Fe-content, 3) solubility under intraphagosomal conditions, 4) value and sign of the surface potential of the particle, 5) hydrophobicity or hydrophilicity, 6) capacity to activate phagocytic leukocytes, and 7) duration of exposure to the particles. The order of importance of these factors in causing severe or fatal pulmonary pathogenicity is estimated to be: 1 > 3 > 7 > 6 ≫ 5 > 4 > 2. The order of pathogenicity of the minerals is estimated as: amphibole asbestos: crocidolite, tremolite, amosite > erionite > serpentine asbestos: chrysotile > talc > silica > simple metal oxides. Particle length, duration of exposure to the particles, and pre-treatment of the particles may however enhance the pathogenic potential of any of the lower-ranked particles.
Image enhancement systems are important diagnostic tools in the detection of laryngeal pathologies. This study aimed to compare three different image enhancement systems: professional image enhancement technology, Image1 S and narrow-band imaging.
Method
Using the three systems, 100 patients with laryngeal lesions were investigated using a flexible and a 30° rigid endoscope. The lesions were diagnosed by three experts and classified using the Ni classification. The findings were compared.
Results
Lesions classified as ‘benign’ were histopathologically confirmed in 50 per cent of patients, malignant lesions were confirmed in 41 per cent and recurrent respiratory papillomatosis were confirmed in 9 per cent. There was no significant difference between the experts’ assessments of each image enhancement system.
Conclusion
The three systems give comparable results in the detection of laryngeal lesions. With two additional systems, more users can perform image-enhanced endoscopy, resulting in a broadly available tool that can help to improve oncological assessment.
The 2014 British Thyroid Association guidelines acknowledged the value of risk-stratifying thyroid nodules by utilising an ultrasound reporting system (‘U’ classification). This study assessed whether using pre-existing parameters in combination can better stratify patients’ malignancy and completion thyroidectomy risks.
Method
A multicentre, retrospective, observational review identified 936 NHS Greater Glasgow and Clyde patients from pathology records who underwent hemithyroidectomy between 1 January 2014 and 31 December 2019.
Results
A total of 308 patients had thyroid malignancy, 180 (58.4 per cent) progressed to completion thyroidectomy. A nodule classified as ‘U3’ (indeterminate) was associated with a 35.4 per cent chance of malignancy and a 21.6 per cent risk of requiring completion surgery. Amalgamation of ‘U’ score with Thy score enhanced risk prediction. The malignancy rate in U3, Thy-3f nodules was 38 per cent, and 21 per cent required completion surgery. The malignancy and completion thyroidectomy rates were comparatively lower for U3, Thy-3a nodules (22 per cent and 14.3 per cent, respectively).
Conclusion
Combining ultrasound ‘U’ score and Thy score improves pre-operative thyroid nodule risk stratification, leading to better informed patients regarding the risks of malignancy and completion surgery. A move towards an integrated assessment approach should be considered.
So far, female physicians have played a minor role in scientific studies of Nazi victims; this also applies to specialists in pathology. Against this background, the present study examines the biographies of the outstanding Jewish pathologists Rahel Rodler (1878–1944), Ruth Silberberg (1906–97), Lotte Strauss (1913–85) and Zelma Wessely (1914–2004). The focus is on their roles as women scientists and their fateful careers after the Nazi rise to power, embedded in the context of the position of women in medical studies and the medical profession of their time as well as in the subject of pathology. The study is primarily based on archival sources from various German, Austrian and Swiss state and university archives, from the British National Archives and from the National Archives and Records Administration in Washington DC. The paper provides three key findings: (1) The four female pathologists were rare exceptions in the contemporary pathological scientific community with a quantitative share of less than 5%. (2) They experienced discrimination on two levels (gender and ‘race’). (3) Thanks to professional excellence and continued dedication, three of the four female pathologists were able to escape from Nazi Germany and achieve remarkable careers in emigration. It can be concluded that Rodler, Silberberg, Strauss and Wessely rose to female role models and pioneer scientists in contemporary pathology.
In this short commentary I recall a long-term experiment that was sketched out to determine if the low incidence of mammary cancer in dairy animals reflects a low incidence in these species generally or is the result of a protective effect of early pregnancy and long lactations. Although that experiment was never done, I discuss these questions in the light of developing knowledge on the incidence of cancer in ruminants generally and in the mammary gland in particular.
The decision to perform euthanasia in geriatric zoo mammals is usually a highly complex procedure involving ethical, medical, emotional and sometimes political factors. However, subsequent necropsies show that the pathological changes of organs and/or the musculoskeletal system are often already advanced. Therefore, we hypothesise that euthanasia is often delayed to the detriment of the animal's welfare. The purpose of this study was to facilitate and establish an initial, objective, decision-making framework for the euthanasia of geriatric zoo mammals. A scoring-system to assess the physical condition and quality of life in ageing zoo mammals is presented, based on retrospective and prospective investigation of 70 geriatric zoo mammals in five European zoos. Medical records and necropsy reports were studied in retrospective cases. Symptoms were monitored and recorded in prospective cases. Radiographic investigations under general anesthesia or at necropsy were performed additionally. A significant association between symptoms and pathological findings revealed that 36.9% (n = 24/65) of examined animals (n = 41/65) had pathological alterations to the musculoskeletal system and 26.2% (n = 17/65) suffered from neoplasia. Based on the individual reports, 28 veterinarians from different fields of veterinary medicine concluded that these animals had mild to severe pain, discomfort and a significantly reduced quality of life, thus strongly reducing welfare. The proposed scoring system includes all of these factors and offers a simple and reliable tool to support decision-making for euthanasia in geriatric zoo mammals.
The relationships between pathology severity and pain severity are reviewed using the literature available for humans. The aim is to help veterinary radiologists, physicians and pathologists recognise the disorders in which severity of a lesion is likely to be related to the severity of pain or to incipient pain. Specific features or lesions within the following conditions showed a relationship with pain score, which was usually assessed with a visual analogue scale: inflammation; pancreatitis; ileitis; mucositis; fasciitis; synovitis; arthritis; lower back pain; disc herniation; sciatica; scoliosis; myalgia; cancer; arteriosclerosis; skin ulcers; mastalgia; skin and oral neuropathies; endometriosis; hepatopathy and chronic pulp diseases of the teeth. As experience with magnetic resonance imaging grows, there will be further opportunities to look for quantitative relationships in humans between pathology and pain severities. This information will be useful to veterinarians and other people working with animals in evaluating pain in animals in their care.
Desmoid tumours (aggressive fibromatosis) are rare, locally invasive, benign tumours. The following case represented a diagnostic challenge, because of the uncommon nature of the lesion.
Case report
A 26-year-old woman, who had previously undergone middle-ear surgery for cholesteatoma, presented with a painful swelling involving the post-auricular area and the conchal bowl. Initially, it was believed to be an infective process related to the surgery or an unusual cholesteatoma recurrence. Following investigations, which involved imaging and histology, the swelling was diagnosed as a desmoid tumour, and the patient received chemotherapy.
Conclusion
Two incidences of paediatric desmoid tumours affecting the ear have been described in the literature, but there is no previous report of a desmoid tumour related to ear surgery. Desmoid tumours have, however, been reported following trauma, including surgery.
This book will enable practitioners to understand the many complex intricacies of immunohistochemistry (IHC) and make best use of this powerful analytical tool. Providing a thorough grounding in the fundamentals of immunohistochemistry, the book includes several chapters on robotics and automation technology, giving key information on the design of machines and tips to maximise workflow efficiencies. The relationship between IHC and molecular pathology is explained clearly, demonstrating the increasing impact on personalized medicine and targeted therapies for cancer patients. The staining protocol is deconstructed, allowing the reader to adapt it for a variety of diagnostic and research applications. Written by experts at the forefront of hospital immunohistochemistry, there is a strong emphasis on practical guidance on a range of techniques as well as troubleshooting of common problems driven by the authors' experiences. Extensively illustrated with high-quality colour images, this is an invaluable resource to all pathology practitioners utilising the technique.
This chapter provides an overview of the components of the evolving conceptual model since the 1988 Spitak earthquake that guided the intervention and research arms of our work in Armenia. With the concept of traumatic stress as the gateway to post-trauma sequelae and recovery, we recognized the important contributions made by post-trauma adversities and the pervasiveness of trauma and loss reminders in the aftermath. Individual and ecological factors were seen as making powerful contributions to the impact and course of recovery, especially in terms of factors associated with resistance, resilience, vulnerability, adjustment, maladjustment, and pathology. The traumatic stress pathway is embedded in a developmental perspective, with the understanding that child, adolescent, and adult development plays an overarching role across all aspects of the conceptual framework. In addition, cultural and religious factors are also seen as integral. Implications of the conceptual model for data collection metrics and methodology, as well as intervention strategies are also discussed.
Hirsutism is a common endocrine disorder affecting 5–10% of women of reproductive age. A thorough history, physical examination and selected laboratory tests will confirm the underlying cause. This chapter reviews various causes and clinical management of hirsutism. Counselling, lifestyle modifications, mechanical hair removal and selected medical therapies can be used to reduce the degree of hirsutism and to improve self-esteem. Combined oral contraceptive pill is the first-line therapy for hirsutism, provided there has been no contraindication. At least 6–9 months of treatment may be necessary before an effect can be observed.
Imaging is an indispensable diagnostic tool in gynaecological practice. Transvaginal ultrasound (TVS) is most often used in an office environment as an adjunct to clinical examination. Transabdominal ultrasound is employed in specific applications and often as a first step before TVS by non-gynaecologists, while MRI and CT are used selectively as secondary tests for specific indications. Perioperative imaging is increasingly popular in clinical practice. In the first section, the essentials of the ultrasound technique and image optimization skills will be described as well as professional attributes necessary for safe ultrasound practice. In the clinical section, the prescribed approach was based on presenting symptoms as is the case in clinical practice where patients are referred or present themselves with a complaint. It is critical for ultrasound practitioners to accurately recognize normal features easily and, likewise, in the differential diagnosis of abnormal findings, they should master the salient features that will ultimately establish a diagnosis.
