Article Synopsis
  • Subjective complaints, like pain and fatigue, are crucial for diagnosing illnesses but lack objective measures, requiring clinicians to rely on patient reports.
  • Distorted reports can occur, so it's important for clinicians to clarify and validate these symptoms to avoid misdiagnoses and inappropriate treatments.
  • The text discusses the need to distinguish between actual signs of illness and "healthy suffering" to prevent unnecessary medicalization, especially when assessing conditions like fatigue.

Article Synopsis
  • Giant cell arteritis (GCA) is a type of blood vessel inflammation diagnosed primarily through a procedure called temporal artery biopsy (TAB).
  • This case report discusses how frozen section analysis during TAB can provide quick diagnostic results that help in starting treatment right away.
  • The authors suggest more research into using frozen section analysis to potentially prevent the need for additional biopsies in patients suspected of having GCA.

: Neuropsychological, neurodevelopmental, or minimal cerebral dysfunctions (MCD) can be found in many patients with mental disorders. They can be masked by other symptoms, impair the course of the illness, and impair work and social participation. Despite a long history of research, there is still a lack of data on the spectrum, prevalence, and consequences of these dysfunctions in patients with chronic illness.

In 2022, the World Health Organization (WHO) and International Consensus Classification (ICC) recognized as an entity-defining alteration in myeloid neoplasms, yet with differing criteria that could lead to discrepant diagnoses and affect clinical trial eligibility. We studied 67 patients with mutant myeloid neoplasms, reclassifying them using both criteria. While most cases fulfill the criteria for mutant defined entities, most discrepancies were found in cases with ≥20% blasts.

A rare lymphoproliferative disorder involving thrombocytopenia (T), anasarca (A), fever (F), reticulin fibrosis (R), renal dysfunction (R), and organomegaly (O), called TAFRO syndrome, was first reported in 2010. Considered a variant of idiopathic multicentric Castleman's disease, the recent discovery and rarity of this syndrome pose challenges to diagnosis and management. Herein, we review three pediatric cases, including an infant, that illustrate the heterogeneity of TAFRO syndrome.

A problem in psychotherapy is the limited availability of psychotherapists. This can not only delay the start of therapy but also curtail the number of sessions and the therapeutic dosage. An option to extend the therapeutic dose without an increase in therapist time may be to combine group psychotherapy with a self-help group.

Multiple myeloma (MM) is an incurable malignant plasma cell neoplasm, representing the second most common hematopoietic cancer. As plasma cell neoplasms are clonal and often secrete a monoclonal protein (M-spike), laboratory diagnosis is usually straightforward, especially when ancillary studies such as immunohistochemistry, flow cytometry, and protein electrophoresis are available in addition to microscopic examination. Despite the repertoire of diagnostic tools, rare cases pose diagnostic dilemmas, especially when reagent antibodies do not react as expected, extent of disease is patchy, or when disease occurs in unique age groups.

Background: Outpatient psychotherapy is qualitatively and quantitatively an important treatment option for patients with psychological disorders. Additionally, there is the option of inpatient care, including psychosomatic rehabilitation units. There is a lack of data on the cooperation between the ambulatory and the inpatient sector, and on which patients in outpatient psychotherapy have already been in psychosoamtic rehabilitation or should be admitted.

This study explores the effectiveness of asynchronous video material as a supplementary educational tool for trainees in hematopathology. Traditional pedagogical methods often rely heavily on faculty involvement, potentially limiting the breadth of information trainees receive due to constraints in faculty time and the variety of cases covered in a limited time interval/rotation. Asynchronous video-based learning presents a potential solution to these challenges.

Background: Treatment of (chronic) mental disorders must focus on both reducing symptoms and improving social and work participation by social medicine treatments and counselling. The objective of this study was to compare psychotherapy patients who are fit or unfit for work to describe similarities and differences regarding patient status and interventions.

Methods: Interviews were performed with 73 cognitive behavior therapists and 58 psychodynamic psychotherapists about 188 and 134 recent cases they had seen, respectively.

Early life stress (ELS) is linked to an elevated risk of poor health and early mortality, with emerging evidence pointing to the pivotal role of the immune system in long-term health outcomes. While recent research has focused on the impact of ELS on inflammation, this study examined the impact of ELS on immune function, including CMV seropositivity, inflammatory cytokines, and lymphocyte cell subsets in an adolescent cohort. This study used data from the Early Life Stress and Cardiometabolic Health in Adolescence Study (N = 191, aged 12 to 21 years, N = 95 exposed to ELS).

Objective: The purpose of this study was to compare the self- and observer ratings of capacity limitations in patients with neurological conditions. Research on this topic is relevant for assessing the patients' ability to participate in work and social life and improving collaborative patient-clinician relationships.

Method: The self- and observer ratings of capacity limitations in a sample of = 245 patients with neurological conditions from a rehabilitation facility were compared and assessed using the short rating of activity limitations and participation restrictions in mental disorders according to the International Classification of Functioning, Disability and Health (Mini-ICF-APP) and the equivalent self-rating questionnaire (Mini-ICF-APP-S).

Objectives: Novel histopathologic prognostic factors are needed to identify patients with follicular lymphoma (FL) at risk of inferior outcomes. Our primary objective was to evaluate the Ki-67 proliferative index in follicular and interfollicular areas in tissue biopsy specimens from patients with newly diagnosed FL and correlate with clinical outcomes. Our secondary objective was to correlate PD-L1 and LAG-3 with clinical outcomes.

Objective: In epidemiological and experimental research, high folic acid intake has been demonstrated to accelerate tumor development among populations with genetic and/or molecular susceptibility to cancer. Neurofibromatosis type 1 (NF1) is a common autosomal dominant disorder predisposing affected individuals to tumorigenesis, including benign plexiform neurofibromas; however, understanding of factors associated with tumor risk in NF1 patients is limited. Therefore, we investigated whether pregestational folic acid intake modified plexiform-like peripheral nerve sheath tumor risk in a transgenic NF1 murine model.

Objective: "Disorders specifically associated with stress" are receiving increasing attention in clinical practice, research, and modern classification systems of mental disorders. This includes not only reactions to "extremely threatening or horrific events" as it is characteristic for "post-traumatic stress disorders" but also a variety of day-to-day experiences. Examples are experiences of injustice, humiliation, or breach of trust which can have dire psychological consequences such as feelings of embitterment, a strong and crippling emotion.

Multiple myeloma (MM) remains an incurable plasma cell (PC) malignancy. Although it is known that MM tumor cells display extensive intratumoral genetic heterogeneity, an integrated map of the tumor proteomic landscape has not been comprehensively evaluated. We evaluated 49 primary tumor samples from newly diagnosed or relapsed/refractory MM patients by mass cytometry (CyTOF) using 34 antibody targets to characterize the integrated landscape of single-cell cell surface and intracellular signaling proteins.

Gastrointestinal (GI) stromal tumors arise from the interstitial cells of Cajal and are rare in the pediatric population. The most common clinical manifestation is anemia secondary to GI bleeding. Endoscopy is commonly used for diagnostic and therapeutic interventions of an obstructing mass or gastrointestinal bleed, while experience with endoscopic ultrasound (EUS) and EUS fine needle aspiration (EUS-FNA) for pediatric patients with suspected gastric tumors is limited.
