Lipid keratopathy (LK) is a rare ophthalmological condition characterized by a progressive reduction in visual acuity caused by corneal opacification due to central lipid accumulation. LK is ...characterized by lipid deposits, cholesterol clefts, and neovascularization (NV) leading to disruption in corneal optical quality. LK classification includes a primary and secondary form which depend on pre-existing corneal or systemic disorders and the evidence of NV. Secondary LK is typically associated with a prior occurrence of herpetic infection, such as herpes zoster keratitis. Patients with LK usually present with progressive vision loss and dense cream-colored corneal opacification. Treatment modalities include conservative and surgical approaches focused on corneal NV elimination. When evaluating corneal lipidosis, it is crucial to consider a range of differential diagnoses, including corneal arcus, Schnyder corneal dystrophy, and other corneal deposit conditions. We report a case of a 62-year-old male with herpes zoster keratitis complicated with LK. He presented with painless progressive vision loss and corneal scarring, which raised suspicion about LK diagnosis. This paper emphasizes the importance of correlating clinical and histological findings for accurate LK diagnosis.
Background: This study aims to analyze the impact of the COVID-19 pandemic on the clinical, pathological, and surgical characteristics of acute appendicitis (AA) at the University Hospital Centre ...(UHC) Zagreb. Methods: This retrospective study analyzed demographic, clinical, and surgical data from consecutive AA patients. Data were collected from an electronic database for two periods: 1 January to 31 December 2019 (pre-COVID-19), and 11 March 2020, to 11 March 2021 (COVID-19 pandemic). Results: During the two study periods, 855 appendectomies were performed, 427 in the pre-pandemic, and 428 during the pandemic. Demographic data were comparable between groups. There was statistically no significant difference in the type of appendectomy (p = 0.33) and the median hospital length of stay (3; (2–5) days, p = 0.08). There was an increase in the conversion rate during the pandemic period (4.2% vs. 7.7%, p = 0.03). The negative appendectomy rate and the incidence of perforated AA did not differ significantly (p = 0.34 for both). Conclusions: We did not observe a significant increase in the rate of AA complications during the COVID-19 pandemic at the UHC Zagreb. This may be attributed to two factors: (1) AA was diagnosed and treated as an emergency, which remained available during the pandemic, and (2) diagnostic and therapeutic protocols remained unaltered. We recommend a laparoscopic approach even during the COVID-19 pandemic.
Ancillary diagnostic tests are frequent in dermatopathology practice. Publications on their accuracy influence their utilization. The transparency and completeness of these publications are unknown.
...We performed a cross-sectional study on diagnostic accuracy studies in dermatopathology published between 2020 and 2022 for compliance with Standards for Reporting of Diagnostic Accuracy Studies (STARD) and the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2).
14.67 ± 3.02 STARD items were reported in 62 publications (range, 9.5-23.5 out of the recommended total of 30). More items were reported in high-impact factor journals (16.01 vs. 13.32, p = 0.0002) and journals that endorsed STARD in their author instructions (17.22 vs. 14.11, p = 0.0039). Less than 10% of publications reported quantifiable hypotheses, sample size calculations, flow diagrams, or study registrations. The risk of bias by our analysis of QUADAS-2 criteria was high or uncertain for index test interpretation (36/62, 58%) and patient selection (44/62, 71%).
Publications on dermatopathology tests are exploratory studies without prespecified hypotheses or study designs. They do not meet the criteria for transparent reporting. We suggest that medical journal leadership should consider updating their instructions with more explicit guidance on recommended manuscript elements.
Aortic homografts are composed of aortic roots and variable lengths of the arch and ascending aorta, harvested from donor hearts. They are primarily used in extensive aortic root endocarditis due to ...its resistance to reinfection. They are, however, prone to structural failure. Redo aortic root surgery is challenging, especially in the setting of aneurysms or pseudoaneurysms (PSAN) lying immediately posterior to the sternum or adhering to it. We present a 43-year-old female with two aortic homograft pseudoaneurysms following her fourth aortic valve and ascending aortic procedure. The first PSAN was described as immediately cranial to proximal homograft anastomosis, measuring 21x8 millimeters. It harbored potential for intraoperative rupture because of its proximity to the posterior sternal table. The second one was 36x20 millimeters, adjacent to the distal homograft anastomosis. The surgical plan entailed institution of peripheral hypothermic cardiopulmonary bypass due to an almost inevitable risk of bleeding from the retrosternal pseudoaneurysm. While the actual sternotomy was uneventful, the PSAN ruptured after sternal retraction. The ensuing massive bleeding was expected and was success- fully managed during hypothermic circulatory arrest. The patient had an unremarkable postoperative course and was discharged home.
The coexistence of mental and physical health illnesses could be accounted for by an underlying general disease factor (termed d-factor), reflecting theoretical underpinnings based on possible ...genetic and pathophysiological overlapping mechanisms. This study evaluated whether the d-factor underlies mental and physical health illnesses in adolescents. A series of confirmatory factor analyses were conducted using data from 1120 adolescents. The proposed common underlying factor, we believe is the d-factor, was consistently present across different modeling approaches, including unidimensional, correlated-factor, and bifactor models. The best model fit was achieved with the bifactor model represented by mental, neurological, and psychical conditions tested. The first compelling evidence was provided supporting the existence of the transdiagnostic d-factor in youth, opening the door to innovative research of comorbid mental and physical health conditions.The coexistence of mental and physical health illnesses could be accounted for by an underlying general disease factor (termed d-factor), reflecting theoretical underpinnings based on possible genetic and pathophysiological overlapping mechanisms.

New research shows that the prevalence of neurodevelopmental disorders, such as attention-deficit/hyperactivity disorder (ADHD), is increased in children and adolescents as well as in adults with ...chronic pain, compared to those without chronic pain. Children and adolescents with ADHD also have an increased incidence of various physical conditions associated with pain, and they more frequently suffer from inflammatory diseases. Moreover, parents of children with ADHD can often suffer from pain conditions. These epidemiological and clinical observations form the scientific basis of our study, which aims to map the relationships between ADHD, altered pain experiences/central sensitization, and inflammation in children and adolescents. We will investigate the presence of central sensitization in children and adolescents with newly diagnosed ADHD and compare it with those who have not been diagnosed with ADHD. Participants (and their biological parents) will complete surveys about their somatic health, pain experience, and quality of life. Biological samples (saliva and stool) will be collected, aiming to utilize proteome and metabolome data to discover disease mechanisms and to predict, prevent and treat them. The results from our investigation should enable an expanded understanding of the pathophysiology behind both ADHD and pain/central sensitization. Presently, there are no established protocols for addressing psychiatric symptoms when examining patients with pain conditions in a somatic care setting, nor is there any knowledge of offering patients with ADHD or other neurodevelopmental disorders adapted treatments for pain conditions. Our results, therefore, can contribute to the development of new treatment strategies for pathological pain conditions in children and adolescents with ADHD. They may also increase awareness about and provide opportunities for the treatment of attention and impulse control problems in children and adolescents with pain syndromes.

The prevalence of pain in children and adolescents with psychiatric conditions is rarely investigated. The aims of the current study were to (a) describe the prevalence of headaches and abdominal ...pain in children and adolescents with psychiatric conditions, (b) compare the prevalence of pain in children and adolescents with psychiatric conditions with that in the general population, and (c) investigate the associations between pain experience and different types of psychiatric diagnoses. Families with a child aged 6–15 years who had been referred to a child and adolescent psychiatry (CAP) clinic completed the Chronic Pain in Psychiatric Conditions questionnaire. Information about the child/adolescent's psychiatric diagnosis(es) was extracted from the CAP clinic's medical records. The children and adolescents included in the study were divided into diagnostic groups and compared. Their data were also compared with data of control subjects collected during a previous study of the general population. Abdominal pain was more common among girls with a psychiatric diagnosis (85%) than in the matched control population (62%, p = 0.031). Children and adolescents with neurodevelopmental diagnoses had a higher prevalence of abdominal pain than children and adolescents with other psychiatric diagnoses. Pain conditions in children and adolescents with a psychiatric diagnosis are common and must be addressed.
