[Interpretation of T-cell and NK-cell lymphoid proliferations and lymphomas in the 5th edition of the WHO classification of haematolymphoid tumours].

The 5th edition of the World Health Organization (WHO) classification of haematolymphoid tumours used the hierarchical system to classify T-cell and NK-cell lymphoid proliferations and lymphomas (T/NK-LPD/LYM) based on research advances and clinicopathological characteristics of the diseases. In this edition of classification, tumour-like lesions were included, some tumors were added/deleted, the names or terms of certain diseases were refined, and the diagnostic criteria or subtypes of some diseases were revised. This group of diseases was reintegrated from non-clonal hyperplasia to highly aggressive lymphoma, which would further reflect the nature of T/NK-LPD/LYM and benefit to clinical application.

Antibiotic prescribing practice using WHO Access, Watch and Reserve classification and its determinants among outpatient prescriptions dispensed to elderly population in six community chain pharmacies in Asmara, Eritrea: a cross-sectional study.

OBJECTIVE: To assess antibiotic prescribing practice and its determinants among outpatient prescriptions dispensed to the elderly population. DESIGN: A prescription-based, cross-sectional study. SETTING: Six community chain pharmacies in Asmara, Eritrea. PARTICIPANTS: All outpatient prescriptions dispensed to the elderly population (aged 65 and above) in the six community chain pharmacies in Asmara, Eritrea. DATA COLLECTION AND ANALYSIS: Data were collected retrospectively, between 16 June 2023 and 16 July 2023. Antibiotic prescribing practice was assessed using the 2023 World Health Organization (WHO) Access, Watch and Reserve (AWaRe) classification system. Descriptive statistics and logistic regression were performed using IBM SPSS (V.26.0). P values less than 0.05 were considered as significant. RESULTS: Of the 2680 outpatient prescriptions dispensed to elderly population, 35.8% (95% CI: 34.0, 37.6) contained at least one antibiotic. Moreover, a total of 1061 antibiotics were prescribed to the elderly population. The most commonly prescribed antibiotics were ciprofloxacin (n=322, 30.3%) and amoxicillin/clavulanic acid (n=145, 13.7%). The Access category accounted for the majority of antibiotics (53.7%) with 32.1% from the Watch category. Prescriber qualification (Adjusted Odds Ratio (AOR)= 0.60, 95% CI: 0.44, 0.81) and polypharmacy (AOR= 2.32, 95% CI: 1.26, 4.27) were significant determinants of antibiotic prescribing in the elderly population. Besides, sex (AOR=0.74, 95% CI: 0.56, 0.98), prescriber qualification (AOR=0.49, 95% CI: 0.30 to0.81) and level of health facility (AOR 0.52, 95% CI 0.34 to 0.81) were significant determinants of a Watch antibiotic prescription. CONCLUSION: Antibiotics were prescribed to a considerable number of the elderly population, with more than half of them falling into the Access category. Further efforts by policy-makers are needed to promote the use of Access antibiotics while reducing the use of Watch antibiotics to mitigate risks associated with antimicrobial resistance.

Metastasizing pleomorphic adenoma of the parotid gland: A common tumour with a very unusual presentation / Metástasis de adenoma pleomorfo de la glándula parótida: un tumor frecuente con una presentación muy poco habitual

Metastasizing pleomorphic adenoma is recognized as a subtype of pleomorphic adenoma in WHO classification 5th edition of salivary glands. The controversy pertaining to the entity is the benign features of the disease even at a metastatic site. We present a rare case of left recurrent pre-auricular swelling in a young male reported as metastasizing pleomorphic adenoma. A nineteen-year-old male presented with left preauricular swelling seven years ago which was diagnosed as pleomorphic adenoma and underwent complete excision of tumour. The tumour recurred twice – two and five years after the surgery. At the second recurrence, the level II neck dissection showed multiple encapsulated deposits of pleomorphic adenoma having similar morphology in the cervical soft tissue with no features of high-grade transformation.

La metástasis de adenoma pleomorfo está reconocida como un subtipo de adenoma pleomorfo según la clasificación de tumores de las glándulas salivales de la Organización Mundial de la Salud (OMS), 5ª edición. La controversia sobre la entidad se refiere a las características benignas de la enfermedad, incluso en lugares de metástasis. Presentamos un raro caso, en un varón de 19 años, de inflamación preauricular izquierda recurrente que se comunica como una metástasis de adenoma pleomorfo. El paciente presentó inflamación preauricular izquierda hace siete años, que se diagnosticó como adenoma pleomorfo, y se sometió a una resección completa del tumor, el cual presentó dos recidivas, dos y cinco años después de la cirugía. En la segunda recidiva, la resección a nivel II del cuello mostró múltiples depósitos encapsulados de adenoma pleomorfo de morfología similar en el tejido blando cervical, sin características de transformación de alto grado.

Mesenchymal skin tumors - Novel entities in the 5th edition of WHO classification of skin tumors.

The section on mesenchymal tumors in 5th edition of WHO classification of skin tumors has undergone several changes, the most important of which, as usual, is the inclusion of newly identified tumor entities, which will be the main focus of this review article. These specifically include three novel cutaneous mesenchymal tumors with melanocytic differentiation, and rearrangements of the CRTC1::TRIM11, ACTIN::MITF, and MITF::CREM genes. In addition, EWSR1::SMAD3-rearranged fibroblastic tumors, superficial CD34-positive fibroblastic tumors, and NTRK-rearranged spindle cell neoplasms were newly included. Of the other changes, only the most important ones will be briefly mentioned.

Parathyroid tumors in the 5th edition of the WHO Classification of Tumors of the Endocrine Organs.

The diagnosis of pathological conditions of the parathyroid glands is the answer to clinically more frequently detected hypercalcemic conditions, including MEN syndromes. In routine biopsy practice, enlarged bodies are also a differential diagnosis for the diagnosis of thyroid nodules. In the chapter of parathyroid tumors, the 5th edition of the WHO classification brings changes influenced similarly to other endocrine organs by the increase in genetic information. At the terminological level, the concept of hyperplasia has been narrowed down to secondary hyperplasia, most of the previously primary hyperplasias are referred to as multiglandular parathyroid disease due to evidence of multiglandular clonal proliferations. The term atypical parathyroid tumor replacing atypical adenoma is newly introduced - the uncertain biological behaviour is emphasized. The basic examination includes parafibromin immunohis- tochemistry, the deficiency of parafibromin being an indicator of an inactivating CDC73 mutation and an increased risk of familial forms, or MEN. Methodologically, refinements are introduced in the quantification of mitotic activity per 10 mm2. Oncocytic subtypes have an arbitrarily declared threshold of more than 75% oncocytes. The definition of lipoadenoma (multiplication of both components, more than 50% of adipose tissue in the tumor) is similarly specified. The diagnosis of cancer remains histopathological with unequivocal evidence of invasion, or microscopically verified metastasis.

WHO 2022 updates on follicular cell and c-cell derived thyroid neoplasm.

The latest edition of the WHO Classification of thyroid tumors was released in 2022 and incorporates novel concepts vital to patient management. Thyroid follicular nodular disease is a term used to collectively represent a wide variety of benign and non-neoplastic lesions, including both clonal and non-clonal proliferations that manifest clinically as multinodular goiter. Thyroid neoplasms develop from follicular cells and can be either benign, low-risk, or malignant. To avoid classifying all lesions under 1 cm in diameter as low-risk illnesses, the new classification method highlights the need for subtyping papillary thyroid cancer based on histomorphologic indicators rather than tumor size. Formerly known as the cribriform-morular variety of papillary thyroid carcinoma, this tumor is now more commonly referred to by its more accurate name, cribriform-morular thyroid carcinoma. Its histogenesis is unknown. Similar to the traditional definition of 'poorly differentiated thyroid carcinoma' according to the Turin criteria, the newly defined 'differentiated high-grade thyroid carcinoma' encompasses papillary thyroid cancer, follicular thyroid carcinomas, and oncocytic carcinomas with high-grade characteristics linked to worse prognosis. The squamous cell subtype of anaplastic thyroid cancer has also recently been characterized as a distinct morphologic pattern. In this article, we will discuss the latest revision to the World Health Organization's classification system for thyroid cancer.

[Interpretation of the pathological diagnostic criteria and characteristics of high-grade thyroid follicular-derived carcinoma in the 5th edition WHO classification].

The 5th edition WHO classification of thyroid tumors proposed high-grade non-anaplastic thyroid carcinoma, which includes traditional poorly differentiated thyroid carcinoma (PDTC) and differentiated high-grade thyroid carcinoma (DHGTC), with a prognosis between highly differentiated thyroid carcinoma and anaplastic thyroid carcinoma (ATC), in which about 50% of patients do not take radioactive iodine. Therefore, this classification is of great clinical significance. This article interprets the diagnostic criteria and genetic features of high-grade non-anaplastic thyroid carcinoma in 5th edition WHO classification, comparing with ATC.

The World Federation of Chiropractic Global Patient Safety Task Force: a call to action.

BACKGROUND: The Global Patient Safety Action Plan, an initiative of the World Health Organization (WHO), draws attention to patient safety as being an issue of utmost importance in healthcare. In response, the World Federation of Chiropractic (WFC) has established a Global Patient Safety Task Force to advance a patient safety culture across all facets of the chiropractic profession. This commentary aims to introduce principles and call upon the chiropractic profession to actively engage with the Global Patient Safety Action Plan beginning immediately and over the coming decade. MAIN TEXT: This commentary addresses why the chiropractic profession should pay attention to the WHO Global Patient Safety Action Plan, and what actions the chiropractic profession should take to advance these objectives. Each strategic objective identified by WHO serves as a focal point for reflection and action. Objective 1 emphasizes the need to view each clinical interaction as a chance to improve patient safety through learning. Objective 2 urges the implementation of frameworks that dismantle systemic obstacles, minimizing human errors and strengthening patient safety procedures. Objective 3 supports the optimization of clinical process safety. Objective 4 recognizes the need for patient and family engagement. Objective 5 describes the need for integrated patient safety competencies in training programs. Objective 6 explains the need for foundational data infrastructure, ecosystem, and culture. Objective 7 emphasizes that patient safety is optimized when healthcare professionals cultivate synergy and partnerships. CONCLUSIONS: The WFC Global Patient Safety Task Force provides a structured framework for aligning essential considerations for patient safety in chiropractic care with WHO strategic objectives. Embracing the prescribed action steps offers a roadmap for the chiropractic profession to nurture an inclusive and dedicated culture, placing patient safety at its core. This commentary advocates for a concerted effort within the chiropractic community to commit to and implement these principles for the collective advancement of patient safety.
