Review
BACKGROUND
Functional endoscopy signifies a significant advancement in gastrointestinal examination, integrating motor function assessments alongside routine endoscopy findings. Traditional gastrointestinal endoscopy primarily focuses on the detection of early-stage cancer by identifying morphological changes within the gastrointestinal tract. These alterations include modifications in lumen structure, color tone, and surface patterns, which can be diagnosed using endoscopic images that assess these morphological changes. In contrast, functional endoscopy aims to dynamically evaluate the peristaltic movements of the digestive tract and the presence or movement of reflux of digestive fluids during the endoscopic procedure. It also seeks to identify morphological changes such as hiatal hernias, as observed in conventional endoscopy. Consequently, relying solely on endoscopic images proves inadequate for diagnosis, necessitating continuous observation of these dynamic movements.
SUMMARY
The endoscopic pressure study integrated system (EPSIS) serves as an exemplar of functional endoscopy. It incorporates a stress test to assess the functionality of the lower esophageal sphincter (LES) through intragastric insufflation. A crucial element of EPSIS evaluation is the identification of the scope holding sign (SHS), which signifies LES contraction. EPSIS also encompasses the observation of esophageal peristaltic waves and the auditory detection of burping, providing a comprehensive diagnostic approach while observing the sphincter from a retroflex view on the stomach side. By integrating these dynamic findings, functional endoscopy offers an efficient method for diagnosing functional gastrointestinal diseases, such as gastroesophageal reflux disease (GERD).
KEY MESSAGES
Functional endoscopy combines motor function assessments with traditional endoscopy, enhancing the diagnostic capabilities of gastrointestinal examinations. Traditional endoscopy focuses on identifying morphological changes, while functional endoscopy evaluates dynamic movements, reflux, and sphincter functionality. EPSIS exemplifies functional endoscopy, featuring a stress test and the SHS for LES contraction assessment. EPSIS provides a comprehensive approach to diagnose GERD by integrating dynamic observations.

Review
Complex regional pain syndrome (CRPS) is a chronic disease that affects a limb following an injury or trauma. The CRPS associated with symptoms, including severe pain, swelling, as well as changes in skin color and temperature. Treatment of CRPS requires a multidisciplinary approach, with a focus on personalized treatment plans and addressing psychological factors. This review provides an overview of updates in the diagnosis and treatment of CRPS. There are clinical criteria for diagnosing CRPS, including persistent pain and swelling. The CRPS can also be diagnosed with imaging and laboratory tests. Novel insights into treatment approaches for CRPS have been gained from advances in understanding its pathophysiology. Treatment of CRPS includes both pharmacological and non-pharmacological interventions. The latest guidelines for CRPS treatment emphasize the importance of early diagnosis and intervention, personalized treatment plans, and addressing psychological factors in managing CRPS.

Review
Thoracic outlet syndrome is an uncommon and controversial syndrome. Three different diagnoses can be made based on the compressed structure, arterial TOS, venous TOS, and neurogenic TOS, though combinations do exist as well. Diagnosing NTOS is difficult since no specific objective diagnostic modalities exist. This has resulted in a lot of controversy in recent decades. NTOS remains a clinical diagnosis and is mostly diagnosed based on the exclusion of an extensive list of differential diagnoses. To guide the diagnosis and treatment of TOS, a group of experts published the reporting standards for TOS in 2016. However, a consensus was not reached regarding a blueprint for a daily care pathway in this document. Therefore, we constructed a care pathway based on the reporting standards for both the diagnosis and treatment of NTOS patients. This care pathway includes a multidisciplinary approach in which different diagnostic tests and additional imaging techniques are combined to diagnose NTOS or guide patients in their treatment for differential diagnoses. The aim of the present work is to discuss and explain the diagnostic part of this care pathway.

Review
CONTEXT.—
Histopathologic diagnosis of adenocarcinoma of the prostate is based on light-microscopic examination of hematoxylin-eosin-stained tissue sections. Multiple factors, including preanalytic and analytic elements, affect the ability of the pathologist to accurately diagnose prostatic adenocarcinoma. False-negative diagnosis, that is, failure to diagnose prostatic adenocarcinoma, may have serious clinical consequences. It is important to delineate and understand those factors that may affect and cause histopathologic false-negative diagnoses of prostatic adenocarcinoma.
OBJECTIVES.—
To review common factors involved in histopathologic underdiagnosis of prostatic adenocarcinoma, including the following: (1) tissue processing and sectioning artifacts, (2) minimal adenocarcinoma, (3) deceptively benign appearing variants of acinar adenocarcinoma, (4) single cell adenocarcinoma, and (5) treatment effects.
DATA SOURCES.—
Data sources included published, peer-reviewed literature and personal experiences of the senior author.
CONCLUSIONS.—
Knowledge of the reasons for histopathologic false-negative diagnosis of adenocarcinoma of the prostate is an important component in the diagnostic assessment of prostate tissue sections. Diagnostic awareness of the histomorphologic presentations of small (minimal) adenocarcinoma; deceptively benign appearing variants including atrophic, foamy gland, microcystic, and pseudohyperplastic variants; single cell carcinoma; and treatment effects is critical for establishment of a definitive diagnosis of adenocarcinoma and the prevention of false-negative diagnoses of prostate cancer.

Review
Bronchoscopy has a low risk of complications when diagnosing peripheral lung lesions suspected of malignancy, however the procedures do not always determine a diagnosis. Several modalities have been invented to improve the diagnostic yield, including radial endobronchial ultrasound and electromagnetic navigation, which are currently used by several departments in Denmark. Augmented fluoroscopy, CT-guided bronchoscopy and robotic bronchoscopy are not yet available in Denmark, but may improve the diagnostic work-up, as argued in this review.

Review
The standard diagnostic modalities for gastrointestinal (GI) diseases have long been endoscopy and barium enema. Recently, trans-sectional imaging modalities, such as computed tomography and magnetic resonance imaging, have become increasingly utilized in daily practice. In transabdominal ultrasonography (US), the bowel sometimes interferes with the observation of abdominal organs. Additionally, the thin intestinal walls and internal gas can make structures difficult to identify. However, under optimal US equipment settings, with identification of the sonoanatomy and knowledge of the US findings of GI diseases, US can be used effectively to diagnose GI disorders. Thus, the efficacy of GIUS has been gradually recognized, and GIUS guidelines have been published by the World Federation for Ultrasound in Medicine and Biology and the European Federation of Societies for Ultrasound in Medicine and Biology. Following a systematic scanning method according to the sonoanatomy and precisely estimating the layered wall structures by employing color Doppler make diagnosing disease and evaluating the degree of inflammation possible. This review describes current GIUS practices from an equipment perspective, a procedure for systematic scanning, typical findings of the normal GI tract, and 10 diagnostic items in an attempt to help medical practitioners effectively perform GIUS and promote the use of GIUS globally.

Review
Ocular cytology specimens are small, with limited options for a repeat biopsy. Appropriate handling of these specimens and triaging for ancillary testing can be taxing. In this article, the author reviews a selection of potentially challenging diagnoses and current common practices and methods used in diagnosing ocular diseases by cytology. The majority of cytology specimens submitted for evaluation of ocular diseases can be divided into 3 major categories: surface epithelial corneal and conjunctival cytology samples, intraocular fluids from the anterior (aqueous fluid) or posterior (vitreous fluid) chambers of the eye, and intraocular fine-needle aspiration specimens. The clinical findings, testing, and cytologic features of ocular surface epithelial infections, inflammations and neoplasia are discussed; and challenges in processing and diagnosing intraocular infections, chronic uveitis, and vitreoretinal lymphoma are reviewed. Novel molecular testing in the cytologic diagnosis and classification of uveal melanoma also is explored. Cytology evaluation of corneal epithelial and stromal cells, anterior chamber and vitreous samples, and fine-needle aspiration biopsies can provide detailed diagnostic findings to aid in the treatment and follow-up of patients with ocular diseases.

CONTEXT
There is no consensus on the correlation between clinical experience and accuracy in diagnosing somatic dysfunctions, which makes it difficult to justify the use of more subjective measures to evaluate this important association. To better understand this relationship, palpatory forces can be observed while diagnosing a somatic dysfunction.
OBJECTIVE
To quantify the pressure applied in diagnosing lumbar somatic dysfunction, find a correlation between accuracy of diagnosis and palpation pressure, set the standards for palpation, and develop precise palpatory skills for osteopathic medical students.
METHODS
The palpatory forces were evaluated between participants with varying experience levels (osteopathic medical students and attending physicians from the New York Institute of Technology College of Osteopathic Medicine). Two osteopathic physicians confirmed an L5 somatic dysfunction diagnosis in a volunteer standardized patient (SP), who served as the control. Participants then palpated the lumbar segment of the SP in a prone position with F-Scan System (TekScan) sensors, which recorded the amount of pressure and time used to reach a full diagnosis.
RESULTS
Participants (11 osteopathic medical students and 10 attending physicians) who diagnosed an L5 somatic dysfunction consistent with the SP's diagnosis had less of a difference in peak force (mean [SD] difference, 62.50 [325.7] g/cm2) between the contact points (right hand vs left hand). In contrast, participants with a dissimilar L5 diagnosis from the SP's had a mean (SD) difference in peak force of 319.38 (703.1) g/cm2. Similarly, the difference in the mean (SD) force of palpation between the contact points was lower in participants who made the correct diagnosis (16.81 [117.4] g/cm2) vs those who made an incorrect diagnosis (123.92 [210.3] g/cm2). No statistical significance was found between the diagnostic accuracy of the students and physicians (P=.387) or the time taken to reach a diagnosis (P=.199).
CONCLUSION
We observed that using equal pressures in both hands while palpating a lumbar segment correlates to more accurate somatic dysfunction diagnoses.

Review
PURPOSE OF REVIEW
This review aims to elucidate the limitations of diagnosing metabolic syndrome in adolescents as well as challenges and opportunities in the identification and reduction of cardiometabolic risk in this population.
RECENT FINDINGS
There are multiple criticisms of how we define and approach obesity in clinical practice and scientific research, and weight stigma further complicates the process of making and communicating weight-related diagnoses. While the goal of diagnosing and managing metabolic syndrome in adolescents would be to identify individuals at elevated future cardiometabolic risk and intervene to reduce the modifiable component of this risk, there is evidence that identifying cardiometabolic risk factor clustering may be more useful in adolescents than establishing a cutoff-based diagnosis of metabolic syndrome. It has also become clear that many heritable factors and social and structural determinants of health contribute more to weight and body mass index than do individual behavioral choices about nutrition and physical activity. Promoting cardiometabolic health equity requires that we intervene on the obesogenic environment and mitigate the compounding effects of weight stigma and systemic racism. The existing options to diagnose and manage future cardiometabolic risk in children and adolescents are flawed and limited. While striving to improve population health through policy and societal interventions, there are opportunities to intervene at all levels of the socioecological model in order to decrease future morbidity and mortality from the chronic cardiometabolic diseases associated with central adiposity in both children and adults. More research is needed to identify the most effective interventions.
