Embryonal and pineal tumours.

Embryonal and pineal tumours represent a diverse group of central nervous system (CNS) neoplasms. While many of the small round blue cell tumours that make up the embryonal neoplasms share similar histologic qualities, there are several morphologic and cytologic characteristics that are useful in distinguishing different tumour types. Similarly, pineal parenchymal tumours represent clinically diverse tumours, ranging from benign to overtly malignant. The most recent iteration of the World Health Organization Classification of CNS Tumours expanded greatly on the significance of molecular alterations in brain tumour diagnostics. In this article, we summarize the salient cytologic and histologic features of CNS embryonal and pineal tumours, and highlight diagnostically relevant molecular alterations within each tumour type.

Validation of the Milan system for reporting salivary gland cytopathology: a single institution's 10-year experience.

INTRODUCTION: Fine needle aspiration cytology is often used for the initial diagnosis and management of patients with salivary gland tumors. Because of its global usage, a consensus classification schema was devised in 2018 to initiate universal reporting of salivary gland cytology specimens, termed the Milan system for reporting salivary gland cytopathology (MSRSGC) and composed of distinct diagnostic categories. Few retrospective studies have been undertaken to review the MSRSGC within institutions. MATERIALS AND METHODS: We analyzed salivary gland fine needle aspirations during a 10-year span from 2011 to 2021, categorized each cytology case to fit the MSRSGC, and subsequently reviewed the corresponding surgical resections, if indicated, to determine the rate of malignancy (ROM) and rate of neoplasia. RESULTS: Our ROM was higher (>10%) for the following MSRSGC categories: non-neoplastic, atypia of undetermined significance, and suspicious for malignancy. Also, our data correlated well with the following MSRSGC categories: nondiagnostic, neoplasm-benign, salivary gland neoplasm of uncertain malignant, and malignant. CONCLUSIONS: Although the data were indicative of the ROM for surgically resected salivary gland lesions, the ROM for non-neoplastic lesions could truly be lower given that most lesions in this category will not undergo surgical resection. Additionally, determination of the rate of neoplasia could a tool that could be used to further guide our clinical colleagues.

Physician Body Mass Index and Bias Toward Obesity Documentation Patterns.

BACKGROUND: Many healthcare professionals consider obese individuals to be unmotivated and to lack the willpower to follow through with weight-loss plans. This attitude may result in less effort put into diagnosing, documenting, and treating obesity. Our aim was to assess documentation patterns of obesity and hypertension overall, by primary care specialty, and in relation to provider body mass index (BMI). METHODS: Twenty-two physicians from one outpatient community practice were included: 10 internal medicine and 12 family practice practitioners. We conducted a retrospective review of medical records from a 1-year period to determine provider documentation of obesity and hypertension. RESULTS: A total of 3,275 obese patients were under the care of 6 physicians with normal BMI, yielding an obesity documentation rate of 23.2%. The 10 overweight physicians had 6,218 obese patients and a documentation rate of 33.5%. The 6 obese physicians had 4,014 patients with obesity and a documentation rate of 21.7%. Obesity documentation rates differed between nonobese physicians (BMI 20-29.9 kg/m2) (30.0%) and obese (BMI ≥30 kg/m2) physicians (21.7%) (P<0.001). We found no difference (P=0.132) between documentation rates of normal-weight BMI physicians and obese physicians. The overall documentation rate of obesity (27.5%) was significantly different than the overall documentation rate of hypertension (83.3%) (P<0.001). CONCLUSION: In our study, nonobese physicians were more likely to document obesity, and documentation of obesity lagged significantly in comparison to hypertension. Addressing weight loss in obese patients starts at the provider level. Steps include documenting obesity on the problem list and providing weight-loss advice during each patient encounter.
