Abstract
OBJECTIVES Present-day pathologists may be unfamiliar with the histopathologic features of measles, which is a reemerging disease. Awareness of these features may enable early diagnosis of measles in unsuspected cases, including those with an atypical presentation. Using archived tissue samples from historic patients, a unique source of histopathologic information about measles and other reemerging infectious diseases, we performed a comprehensive analysis of the histopathologic features of measles seen in commonly infected tissues during prodrome, active, and late phases of the disease. METHODS Subspecialty pathologists analyzed H&E-stained slides of specimens from 89 patients accessioned from 1919 to 1998 and correlated the histopathologic findings with clinical data. RESULTS Measles caused acute and chronic histopathologic changes, especially in the respiratory, lymphoid (including appendix and tonsils), and central nervous systems. Bacterial infections in lung and other organs contributed significantly to adverse outcomes, especially in immunocompromised patients. CONCLUSIONS Certain histopathologic features, especially Warthin-Finkeldey cells and multinucleated giant cells without inclusions, allow pathologists to diagnose or suggest the diagnosis of measles in unsuspected cases.

Abstract
Although case reports have suggested an association between severe acute respiratory distress syndrome coronavirus 2 and appendicitis, we found that the overall incidence of appendicitis was stable throughout the pandemic at our tertiary pediatric hospital. Furthermore, we did not find evidence of CoV2 infection in 9 appendicitis tissues. Therefore, we conclude that severe acute respiratory distress syndrome coronavirus 2 infection of the appendix is not a common etiologic cause of pediatric appendicitis.

Abstract
Background Acute cholecystitis is a common complication of cholelithiasis. Delayed diagnosis may constitute morbidity and mortality; therefore, early diagnosis and determining the severity of acute cholecystitis are crucial. Objectives This study aimed to determine the validity of blood procalcitonin (PCT) levels in assessing the severity of acute cholecystitis. Methods The Emergency Department (ED) patients diagnosed as acute cholecystitis were included in the study. Patients were allocated into three severity grades according to the Tokyo Guidelines 2013. PCT level was measured after the clinical and radiological diagnosis of acute cholecystitis in the ED. Results Ninety-five patients diagnosed with acute cholecystitis, among them 48 of were male. Forty patients (42.1%) were allocated to grade 1, 19 (20%) to grade 2, and 36 (37.9%) to grade 3. The median values of PCT were 0.104 ng/ml, 0.353 ng/ml, and 1.466 ng/ml for grade 1, 2, and 3 patients, respectively (p < 0.001). Conclusion Blood procalcitonin levels can be used to determine the severity of acute cholecystitis effectively.

Macrophages and Dendritic Cells Are the Predominant Cells Infected in Measles in Humans. mSphere 2018; 3:3/3/e00570-17.

Abstract
Characterization of human measles cases is essential in order to better assess the data generated in model systems of morbillivirus infection. To this end, we collected formalin-fixed tissue samples from 23 natural measles cases from different areas in the world and different phases of disease ranging from prodromal and acute measles to a persistent infection in an immunocompromised subject. We show that the vast majority of measles virus (MV)-infected cells in epithelia were intraepithelial immune cells that were, in most cases, positive for the CD11c myeloid cell marker. Small numbers of measles virus-infected cytokeratin-positive epithelial cells were also detected in bronchial and appendix epithelia. Dissolution and disruption of uninfected and MV-infected alveolar and bronchial epithelia were prominent features of the measles cases, especially in the established and late phases of the disease. In some instances, this was associated with the formation of MV-infected multinucleated giant cells which expressed CD11c and/or macrophage cell marker 68, a pathological feature also prominently observed in closely associated mucosa-associated lymphoid tissue. Collectively, these data show that resident and inflammatory infiltrating immune cells alter the architecture of respiratory tract epithelia and highlight the necessity for additional research into the function(s) and expression of nectin-4 in human tissues.IMPORTANCE We have brought together a unique collection of 23 human cases of measles infection and studied the types of cells that are infected. This work has not been done with modern technologies such as double labeling with antibodies and confocal microscopy in human cases primarily due to the fact that it is difficult to obtain the material because, fortunately, measles is fatal in only a very small fraction of infected patients. During the past decades, the receptors for measles virus have been elucidated and monkey models have been developed. We found that, in most cases, independently of whether the tissues were obtained early or later in the infection, the primary cell types that were infected were those of the immune system such as lymphocytes, macrophages, and dendritic cells. A very small number of epithelial cells were also found to be infected.

Abstract
Warthin-Finkeldey type giant cells were first described in autopsies performed on young children who died during the highly lethal measles epidemic in Palermo during the winter of 1908. The cells had 8-15 nuclei without identifiable cytoplasm within the germinal centers of lymphoid organs resembling megakaryocytes. We describe a case of Hashimoto thyroiditis with an enlarging substernal throid mass. The resection specimen contained many Warthin-Finkeldey-Like Cells (WFLC) in an extranodal marginal zone lymphoma (MALT type) with focal transformation to diffuse large B-cell lymphoma. The WFLC showed nuclear features similar to those of neighboring follicular dendritic cells (FDCs), favoring the hypothesis that these cells might be the product of fusion of FDCs. This is supported by immunostaining results and the occurrence of similar cells in follicular dendritic cell sarcomas and in "dysplastic" FDCs in hyaline vascular type Castleman disease, a possible precursor of follicular dendritic cell tumors.

Abstract
INTRODUCTION Obstruction of the appendiceal lumen is the primary cause of appendicitis. The most common causes of luminal obstruction are fecaliths and lymphoid follicle hyperplasia. Additionally, bacterial infections or enteric and systemic viral diseases can cause a reaction of the lymphoid follicle. CASE PRESENTATION An 11-year-old boy with active phase of chickenpox presented on our Pediatric surgery emergency department under the impression of acute appendicitis. An appendectomy was performed on the same day. An inflamed and edematous retrocecal appendix was removed during surgery. Histological investigation of the appendix revealed transmural acute inflammation, with diffuse proliferation of inflammatory cells, with characteristic intranuclear inclusion surrounded by a clear halo. The PCR analysis of peripheral blood and appendix tissue specimen revealed positive VZV DNA. CONCLUSION We have shown that varicella-zoster virus infection of the appendix is associated with acute appendicitis and possibly also with severity of the disease.

Abstract
The pathologic spectrum of the inflamed appendix encompasses a wide range of infectious entities, some with specific histologic findings, and others with nonspecific findings that may require an extensive diagnostic evaluation. The appendix is exclusively involved in some of these disorders, and in others may be involved through extension from other areas of the gastrointestinal tract. This review discusses the pathologic features of bacterial, viral, fungal, and parasitic infections affecting the appendix, including adenovirus; cytomegalovirus; Yersinia, Actinomyces, Mycobacterium, or Histoplasma species; Enterobius vermicularis; schistosomiasis; and Strongyloides stercoralis. Pertinent ancillary diagnostic techniques and the clinical context and significance of the various infections are also discussed.

Abstract
Although the involvement of common childhood infections in the aetiology of acute appendicitis has long been conjectured, supporting evidence is largely restricted to a disparate set of clinical case reports. A systematic population-based analysis of the implied comorbid associations is lacking in the literature. Drawing on a classic epidemiological dataset, assembled by the School Epidemics Committee of the United Kingdom's Medical Research Council (MRC) in the 1930s, this paper presents a historical analysis of the association between termly outbreaks of each of six common childhood infections (chickenpox, measles, mumps, rubella, scarlet fever and whooping cough) and operated cases of acute appendicitis in 27 English public boarding schools. When controlled for the potential confounding effects of school, year and season, multivariate negative binomial regression revealed a positive association between the level of appendicitis activity and the recorded rate of mumps (beta=0.15, 95% CI 0.07-0.24, P<0.001). Non-significant associations were identified between appendicitis and the other sample infectious diseases. Subject to data caveats, our findings suggest that further studies are required to determine whether the comorbid association between mumps and appendicitis is causal.

Abstract
The vermiform appendix may react as part of a generalized viral infection, but histological documentation of appendiceal viral infection is rare. Adenovirus has been described in association with mesenteric adenitis and ileocecal intussusception, but to our knowledge there are no well-documented cases of adenoviral appendiceal infection presenting clinically as acute appendicitis without intussusception. We reviewed the pathology records of all appendectomies performed at our institution from 2001 through 2005. All incidental appendectomies and appendices with acute appendicitis or other pathological findings were excluded. We selected all negative appendices with lymphoid hyperplasia and reviewed hematoxylin and eosin-stained slides. Representative sections of each of these cases were immunostained with adenovirus antibody. Eight hundred seventy-seven appendectomies were performed during the study period. Of these, there were 94 cases that had a clinical diagnosis of acute appendicitis and that were pathologically negative. Sixty-three of the 94 cases had lymphoid hyperplasia and were stained for adenovirus. We identified 2 positive cases, which also showed epithelial proliferation and viral inclusions. One involved a 6-year-old male and the other involved a 5-year-old female, without intussusception. Adenovirus can infect the appendix and clinically mimic acute appendicitis without intussusception. We recommend that all negative appendices be evaluated for lymphoid hyperplasia and epithelial viral changes and possibly be stained with immunoperoxidase staining if indicated. We speculate that adenovirus may play a role in the pathogenesis of acute appendicitis.

Abstract
The pathologic spectrum of the acutely inflamed appendix encompasses a wide range of infectious and noninfectious entities. The appendix suffers alone in some of these disorders, and in others may be involved through extension from other areas of the gastrointestinal tract. Although the appendix is the most commonly resected and examined intraabdominal organ, the pathogenesis and etiology of acute nonspecific appendicitis (the most common diagnosis made in this organ) remains enigmatic. This review encompasses the pathology, pathogenesis, and bacteriology of acute appendicitis, as well as controversial issues such as the diagnosis of chronic appendicitis and the significance of a morphologically unremarkable appendectomy specimen in the clinical context of appendicitis. In addition, the pathologic features, pertinent diagnostic techniques, and clinical significance of several specific bacterial, viral, fungal, and parasitic infections affecting the appendix are presented, including adenovirus, cytomegalovirus, Yersinia species, actinomycosis, Mycobacteria species, histoplasmosis, pinworms, schistosomiasis, and Strongyloides stercoralis.

Abstract
Gastrointestinal symptoms, including vomiting, are caused by a variety of infective organisms in children, many of which are self-limiting and resolve within a week, but others are potentially much more serious in their consequences. Diarrhea, vomiting and abdominal pain are common but nonspecific symptoms. Investigation is dictated by the likely causative organism, given the age and presentation of the child. The role of bacteria in the pathogenesis of necrotizing enterocolitis, recognition that Yersinia, Campylobacter and Salmonella may produce symptoms difficult to distinguish clinically from appendicitis, the viral causes of idiopathic intussusception, the occurrence of intussusception after administration of rotavirus vaccine, and the evidence incriminating mycobacterium avium subspecies paratuberculosis in the aetiology of Crohn disease are discussed.
