Abstract
When approaching a case of apparent drug allergy, the consulting clinician should consider a broad differential diagnosis. This article presents a series of cases that could be commonly referred to an allergist for assessment as "drug allergy," however, a real diagnosis exists that mandates a different diagnostic and treatment strategy, including a case of inducible laryngeal obstruction, multiple drug intolerance syndrome, viral rash, seizure due to metastatic malignancy, and hemophagocytic lymphohistiocytosis initially diagnosed as drug reaction and eosinophilia with systemic symptoms. The initial misdiagnoses of these patients delayed or interfered with their medical care, emphasizing the importance of accurate diagnoses for the benefit of our patients.

Abstract
OBJECTIVE Cervical conization is an effective treatment for precancerous lesions. However, in cases where no high-grade lesion is identified in the surgical specimen, managing these patients may be challenging due to the absence of established follow-up protocols for negative conizations. This study aimed to assess the negative conization rates at our institution by histopathological review, identify diagnostic errors, possible risk and recurrence factors and propose follow-up strategies for this group of patients. METHODS A retrospective study from January-2010 to December-2020 analyzed patients with negative conization including all surgical techniques and procedure indications. Biopsy and cervical conizations slides were reviewed and patients who kept a negative result underwent deeper levels sectioning of the paraffin blocks with immunohistochemical stains application: p16, Ki-67 and geminin. Data were compared with a control group composed by 29 women with CIN3. RESULTS Out of 1022 conizations, 186 were negative (18.1%), with 151 cases selected for the study after excluding 35 patients. Following pathology review, 4 patients were excluded due to false-positive cervical biopsy results, 16 for false-negative conization results and 9 for hidden dysplasia identified after deeper sectioning. The remaining 122 patients were considered truly negative cones (11.9%) and exhibited IHC staining with p16 positive in 20.4% of cases, low Ki-67 expression, and low geminin score in most cases. Specimens with CIN 1 had higher prevalence of p16 staining, Ki-67 expression and geminin score when compared to absence of neoplasia, nevertheless geminin had no statistical difference. Older age, higher parity and IHC pattern with negative p16, low Ki-67 and geminin expressions were identified as risk factors for negative cones (p<0.05). Only 10 patients recurred for high-grade lesions, with no statistically significant risk factors identified. CONCLUSIONS The negative conization rate was 11.9%, with diagnostic errors identified across pre-surgical biopsy, cone specimen, and deeper levels. Risk factors included older age, higher parity, low expression of p16, Ki-67 and geminin (p<0.05). Recurrence represented 8.1% of the negative cones, without identification of statistically significant risk factors. Pathological review with deeper level sections and 2-year follow-up are recommended for patients with negative conizations.

Abstract
BACKGROUND Colonic diverticulitis (CD), typically seen in the elderly of Western countries, is increasingly prevalent worldwide, yet data on CD in children and adolescents are scarce. This study explores the characteristics of CD in this younger demographic. METHODS In a multicenter, retrospective review, 104 patients under 20 years diagnosed with CD at four Korean tertiary hospitals from June 2003 to December 2020 were analyzed. Abdominal CT scans were used for diagnosis, with the modified Hinchey classification assessing the severity of CD. RESULTS CD was found in the cecum or ascending colon in 103 (99%) of cases. The mean patient age was 17.24 ± 2.4 years, with males constituting 59.6% of cases. Solitary lesions were noted in 93 (89.4%) of patients. Severity was classified as modified Hinchey stage 0 in 58.7%, stage Ia in 29.8%, and stage Ib in 11.5%, with no cases of stage II or higher. Misdiagnosis as acute appendicitis occurred in six instances. IV antibiotics were administered to 68.3%, and oral antibiotics were sufficient for 24%. Surgical treatment was necessary for two patients. A 7.8% recurrence rate was noted among first-time CD patients, yet all cases were amenable to conservative management. CONCLUSION While uncommon, CD in children and adolescents is a growing concern, with most cases presenting as solitary lesions in the cecum or ascending colon. The severity is typically less than that in adults, and conservative treatment is generally effective. These findings underscore the need for specific management guidelines for pediatric CD, advocating for non-surgical initial approaches.

Abstract
The visceral vasculature is inextricably intertwined with abdominopelvic disease staging, spread, and management in routine and emergent cases. Comprehensive evaluation requires specialized imaging techniques for abnormality detection and characterization. Vascular pathology is often encountered on nondedicated routine imaging examinations, which may obscure, mimic, or confound many vascular diagnoses. This review highlights normal arterial, portal venous, and systemic venous anatomy and clinically relevant variants; diagnostic pitfalls related to image-acquisition technique and disease mimics; and characteristics of common and rare vascular diseases to empower radiologists to confidently interpret the vascular findings and avoid misdiagnosis.

Abstract
Although one of the most common systemic autoimmune disorders, Sjögren disease (SjD) may be overlooked in patients presenting with non-specific symptoms or no complaints of sicca symptoms. SjD is not a condition to be missed as patients could present with serious extra-glandular manifestations, including lymphomas. In this article, we discuss the diagnostic pitfalls of this disorder and encourage physicians to consider carefully the 'non-textbook' presentations.

Abstract
BACKGROUND/PURPOSE To describe a case of bilateral diffuse uveal melanocytic proliferation (BDUMP) that was mistaken for nivolumab-induced Vogt-Koyanagi-Harada disease-like syndrome. METHODS We present the case of a 58-year-old white man with metastatic renal clear cell carcinoma for which he was palliatively treated with IV nivolumab immunotherapy. The patient developed subacute onset of blurry vision and gray spots in the visual fields of both eyes, macular subretinal fluid, thickening of the retinal pigment epithelium, and swollen optic nerve heads. Differential diagnosis included nivolumab-induced Vogt-Koyanagi-Harada disease-like syndrome, and the patient was initially treated with steroids, which gave no improvement. Investigation showed the development of dark-gray patches in the peripheral retina of both eyes and cataract, which prompted reevaluation of the diagnosis, deeming BDUMP most likely. The patient was successfully treated with plasmapheresis. RESULTS The initial presentation of the case was incorrectly diagnosed as nivolumab-induced Vogt-Koyanagi-Harada disease-like syndrome. On repeat studies of the patients' symptoms and imaging, we concluded we had missed signs of BDUMP. CONCLUSION The diagnosis BDUMP was missed in the first evaluation. We present this case to discuss the similarities and differences between this disease and nivolumab-induced Vogt-Koyanagi-Harada disease-like syndrome. More importantly, we want to highlight that reevaluation of the diagnosis on worsening of a disease was key in this unusual case.

Abstract
Hepatic angiosarcoma is an extremely rare primary malignant vascular tumour in children with very poor prognosis. Radiological diagnosis of hepatic angiosarcoma is challenging due to overlapping imaging features with other benign vascular hepatic tumours, particularly infantile hepatic haemangioma. Consumptive hypothyroidism is a condition that is almost exclusively associated with infantile hepatic haemangioma and has never been reported in angiosarcoma. We present a case of hepatic angiosarcoma in a 20-month-old girl, associated with consumptive hypothyroidism and, as a result, initially misdiagnosed as infantile hepatic haemangioma. Radiologists should be aware that consumptive hypothyroidism is not a reliable feature to use in excluding paediatric hepatic angiosarcoma. Biopsy should be performed in patients older than 1 year of age or with atypical imaging features.

Abstract
Classifying diabetes at diagnosis is crucial for disease management but increasingly difficult due to overlaps in characteristics between the commonly encountered diabetes types. We evaluated the prevalence and characteristics of youth with diabetes type that was unknown at diagnosis or was revised over time. We studied 2073 youth with new-onset diabetes (median age [IQR] = 11.4 [6.2] years; 50% male; 75% White, 21% Black, 4% other race; overall, 37% Hispanic) and compared youth with unknown versus known diabetes type, per pediatric endocrinologist diagnosis. In a longitudinal subcohort of patients with data for ≥ 3 years post-diabetes diagnosis (n = 1019), we compared youth with steady versus reclassified diabetes type. In the entire cohort, after adjustment for confounders, diabetes type was unknown in 62 youth (3%), associated with older age, negative IA-2 autoantibody, lower C-peptide, and no diabetic ketoacidosis (all, p < 0.05). In the longitudinal subcohort, diabetes type was reclassified in 35 youth (3.4%); this was not statistically associated with any single characteristic. In sum, among racially/ethnically diverse youth with diabetes, 6.4% had inaccurate diabetes classification at diagnosis. Further research is warranted to improve accurate diagnosis of pediatric diabetes type.

Abstract
BACKGROUND Pseudoachalasia is a rare disease that behaves similarly to achalasia (AC), making it sometimes difficult to differentiate. CASE PRESENTATION We report a case of 49-year-old male with adenocarcinoma of the gastroesophageal junction misdiagnosed as achalasia. No obvious abnormalities were found in his initial examinations including upper digestive endoscopy, upper gastrointestinal imaging and chest computed tomography (CT). During the subsequent introduced-peroral endoscopic myotomy (POEM), it was found that the mucosal layer and the muscular layer had severe adhesion, which did not receive much attention, delayed the clear diagnosis and effect treatment, and ultimately led to a poor prognosis for the patient. CONCLUSIONS This case suggests that when patients with AC found mucosal and muscular adhesions during POEM surgery, the possibility should be considered that the lesion may be caused by a malignant lesion.

Abstract
BACKGROUND The diagnostic process is a key element of medicine but it is complex and prone to errors. Infectious diseases are one of the three categories of diseases in which diagnostic errors can be most harmful to patients. In this study we aimed to estimate the effect of initial misdiagnosis of the source of infection in patients with bacteraemia on 14 day mortality using propensity score methods to adjust for confounding. METHODS Data from a previously described longitudinal cohort of patients diagnosed with monobacterial bloodstream infection (BSI) at the Leiden University Medical Centre (LUMC) between 2013 and 2015 were used. Propensity score matching and inversed probability of treatment weighting (IPTW) were applied to correct for confounding. The average treatment effect on the treated (ATT), which in this study was the average effect of initial misdiagnosis on the misdiagnosed (AEMM), was estimated. Methodological issues that were encountered when applying propensity score methods were addressed by performing additional sensitivity analyses. Sensitivity analyses consisted of varying caliper in propensity score matching and using different truncated weights in inversed probability of treatment weighting. RESULTS Data of 887 patients were included in the study. Propensity scores ranged between 0.015 and 0.999 and 80 patients (9.9%) had a propensity score > 0.95. In the matched analyses, 35 of the 171 misdiagnosed patients died within 14 days (20.5%), versus 10 of the 171 correctly diagnosed patients (5.8%), yielding a difference of 14.6% (7.6%; 21.6%). In the total group of patients, the observed percentage of patients with an incorrect initial diagnosis that died within 14 days was 19.8% while propensity score reweighting estimated that their probability of dying would have been 6.5%, if they had been correctly diagnosed (difference 13.3% (95% CI 6.9%;19.6%)). After adjustment for all variables that showed disbalance in the propensity score a difference of 13.7% (7.4%; 19.9%) was estimated. Sensitivity analyses yielded similar results. However, performing weighted analyses without truncation yielded unstable results. CONCLUSION Thus, we observed a substantial increase of 14 day mortality in initially misdiagnosed patients. Furthermore, several patients received propensity scores extremely close to one and were almost sure to be initially misdiagnosed.

Abstract
AIM To determine the frequency and classification of addenda seen in paediatric brain magnetic resonance imaging (MRI) reports. MATERIALS AND METHODS A retrospective review of the addenda of brain MRI reports from a large tertiary children's hospital was undertaken between January 2013 to December 2021 and a subset of above radiology reports was used to classify addenda over 6-month periods, October to March, spanning 2018 to 2021. A radiology fellow and a medical doctor classified the addenda into previously published categories using their best judgement. RESULTS Out of 73,643 brain MRI reports over 9 years (108 months) included in the study, only 923 reports (1.25%) had addenda. There was a total of 13,615 brain MRI reports from 6-month periods, of which only 179 reports (1.31%) had an addendum. The number of errors according to categories were: observational 88/13,615 (0.65%); interpretational 16/13,615 (0.12%); non-observational and non-interpretative 82/13,615 (0.6%). Notifications to referring physician made in 29/13,615 (0.21%). CONCLUSIONS The overall proportion of addenda to the brain MRI reports of children in the present study was low, at 1.25%. Categorisation of different addenda revealed the most common errors to be observational in 0.65%, including under-reading in the region of interest in 0.25%. Appropriate measures can now be introduced to minimise the error-based addenda further and improve MRI diagnosis in children. Other paediatric practices may choose to follow suit in evaluating their addenda and errors to improve practice.

Abstract
Despite increasing numbers of regulatory approvals, deep learning-based computational pathology systems often overlook the impact of demographic factors on performance, potentially leading to biases. This concern is all the more important as computational pathology has leveraged large public datasets that underrepresent certain demographic groups. Using publicly available data from The Cancer Genome Atlas and the EBRAINS brain tumor atlas, as well as internal patient data, we show that whole-slide image classification models display marked performance disparities across different demographic groups when used to subtype breast and lung carcinomas and to predict IDH1 mutations in gliomas. For example, when using common modeling approaches, we observed performance gaps (in area under the receiver operating characteristic curve) between white and Black patients of 3.0% for breast cancer subtyping, 10.9% for lung cancer subtyping and 16.0% for IDH1 mutation prediction in gliomas. We found that richer feature representations obtained from self-supervised vision foundation models reduce performance variations between groups. These representations provide improvements upon weaker models even when those weaker models are combined with state-of-the-art bias mitigation strategies and modeling choices. Nevertheless, self-supervised vision foundation models do not fully eliminate these discrepancies, highlighting the continuing need for bias mitigation efforts in computational pathology. Finally, we demonstrate that our results extend to other demographic factors beyond patient race. Given these findings, we encourage regulatory and policy agencies to integrate demographic-stratified evaluation into their assessment guidelines.

Abstract
BACKGROUND HIV testing is a critical step to accessing antiretroviral therapy (ART) because early diagnosis can facilitate earlier initiation of ART. This study presents aggregated data of individuals who self-reported being HIV-positive but subsequently tested HIV-negative during nationally representative Population-Based HIV Impact Assessment surveys conducted in 11 countries from 2015 to 2018. METHOD Survey participants aged 15 years or older were interviewed by trained personnel using a standard questionnaire to determine HIV testing history and self-reported HIV status. Home-based HIV testing and counseling using rapid diagnostic tests with return of results were performed by survey staff according to the respective national HIV testing services algorithms on venous blood samples. Laboratory-based confirmatory HIV testing for all participants identified as HIV-positives and self-reported positives, irrespective of HIV testing results, was conducted and included Geenius HIV-1/2 and DNA polymerase chain reaction if Geenius was negative or indeterminate. RESULTS Of the 16,630 participants who self-reported as HIV-positive, 16,432 (98.6%) were confirmed as HIV-positive and 198 (1.4%) were HIV-negative by subsequent laboratory-based testing. Participants who self-reported as HIV-positive but tested HIV-negative were significantly younger than 30 years, less likely to have received ART, and less likely to have received a CD4 test compared with participants who self-reported as HIV-positive with laboratory-confirmed infection. CONCLUSIONS A small proportion of self-reported HIV-positive individuals could not be confirmed as positive, which could be due to initial misdiagnosis, deliberate wrong self-report, or misunderstanding of the questionnaire. As universal ART access is expanding, it is increasingly important to ensure quality of HIV testing and confirmation of HIV diagnosis before ART initiation.

Abstract
Middle ear tumors are diverse, but relatively uncommon. The most frequent tumor in the middle ear is glomus tumor, followed by others such as schwannoma and cholesteatoma. We experienced a case of Mucosa-associated lymphoid tissue hyperplasia as a middle ear tumor. The mass behind tympanic membrane appeared a hypervascular tumor, mimicking a glomus tumor, but the form of multiple separate masses in middle ear and mastoid cavity was the distinguishing feature that set it apart from a glomus tumor. Additionally, another characteristic was its tendency to easily shrink under pressure. This characteristic should be considered when encounter a hypervascular looking middle ear mass.

Abstract
Although contrast-enhanced ultrasound (CEUS) is a widespread and easily manageable technique, image interpretation errors can occur due to the operator's inexperience and/or lack of knowledge of the frequent pitfalls, which may cause uncertain diagnosis and misdiagnosis. Indeed, knowledge of the basic physical and technical principles of ultrasound is needed both to understand sonographic image findings and to evaluate the potential and limits of the method. Like the B-mode ultrasound, the quality of the CEUS examination is also subject not only to the adequate manual skill of the operator but also to his/her deep knowledge of the technique which improves the quality of the image helping avoid misleading artifacts. In this review, the main parameters influencing a CEUS examination will be described by taking into account the most common errors and pitfalls and their possible solutions.

Spierer R, Herskovitz M. Which psychogenic nonepileptic seizure (PNES) patients are more likely to be treated with anti-seizure medications? Seizure 2024; 117:111-114. [PMID: 38368830 DOI: 10.1016/j.seizure.2024.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 02/11/2024] [Accepted: 02/12/2024] [Indexed: 02/20/2024] Open
Abstract
BACKGROUND The average time for psychogenic nonepileptic seizures (PNES) diagnosis is about 7.5 years. Many patients receive inadequate treatment and sometimes even life-threatening treatments such as tracheal intubation during this time. PURPOSE To determine the risk factors for misdiagnosis of PNES as Epilepsy. METHODS The medical records of patients who underwent video-electroencephalogram (EEG) monitoring were reviewed retrospectively. Patients who had PNES without epileptic seizures (ES) were included in this study. Baseline personal and monitoring characteristics were collected. The patients were then divided into two groups based on their therapeutic status. Patients in the treatment group were again divided into two groups based on the number of anti-seizure medications (ASM) they were treated with. RESULTS Fifty-seven patients diagnosed with PNES were included in this study. Thirty-seven patients were under treatment, and 20 patients were not under treatment at the time of monitoring. Motor seizures, abnormal interictal EEG patterns, and pathological brain imaging findings were more frequent among patients in the treatment group (p<0.05). Patients with motor seizures were more likely to be treated with multiple ASM than patients with only dialeptic nonmotor seizures (p<0.05). Lastly, patients in the treatment group were monitored longer and had fewer seizures during monitoring (p<0.05). CONCLUSION PNES patients with abnormal EEG patterns and pathological brain imaging findings are more likely to be treated with ASM. The pure dialeptic nature of seizures is less likely to be misdiagnosed as ES. In addition, patients with such seizures are less likely to be treated with multiple treatment lines.
