Abstract
Background Measles is a highly contagious viral disease that has recently made headlines due to outbreaks in several parts of the world. The disease can cause serious health complications, especially in young children, which has led to concerns about vaccination rates and public health policies. This study aims to investigate and describe the epidemiology, clinical characteristics, and outcomes of measles infection among children in Riyadh. Methodology We conducted a descriptive cross-sectional study among all pediatric patients with confirmed measles infection at a tertiary hospital from January 15, 2023, to March 15, 2023. We collected data including demographic characteristics, clinical presentations, and clinical outcomes. Results A total of 63 confirmed measles cases were reported. Most patients were under four years of age (82.7%), and 85.7% were unvaccinated. Adenovirus was the most common viral coinfection (12.7%). The most common complication was pneumonia (58.7%). Chest X-ray findings reported a localized right parenchymal infiltrate in 19% of patients and a patchy bilateral infiltrate in 15.9% of patients. In addition, 88.9% required hospital admission secondary to dehydration (47.6%) and hypoxia (41.3%). Among admitted patients, 17.5% were admitted to the pediatric intensive care unit (PICU), 9.5% were admitted due to respiratory failure, and 6.3% due to septic shock. Children under one year of age had a higher risk for PICU admission (p < 0.05). The mortality rate was 1.6%. Conclusions Measles is a serious disease that causes significant health effects and incurs high financial costs for public health systems. Vaccination remains the most effective way to prevent measles outbreaks and reduce their impact on individuals and communities.

Abstract
BACKGROUND In 2018-2019, large outbreaks of measles occurred in Israel and in New York City, driven in part by travel of unimmunized children between the 2 communities. METHODS A retrospective chart review was conducted for children tested for measles (March 2018-September 2019) at NYU Langone Health in New York, NY, and in Ramla subdistrict, Israel. Vaccination records were reviewed to determine vaccination status for measles, mumps, and rubella (MMR) at the time of measles testing and 1-year post-testing. RESULTS A total of 264 children were tested for measles, and 102 (38.6%) had confirmed measles. Only 20 (19.6%) of measles-positive cases received a full 2-dose course of vitamin A. 82.4% of children with measles were ≥1 year at the time of diagnosis and fully eligible for MMR vaccine. Of the 100 measles-positive cases with available vaccine records, 63 were unvaccinated at testing, and 27 remained unimmunized against MMR 1 year later. At testing, measles-negative children were significantly more likely to have received MMR than measles-positive children (65.4% vs 37%, P < .01). One year later, 70.4% of measles-negative cases and only 57.1% of measles-positive cases had received MMR vaccine (P = .18). CONCLUSIONS The majority of measles cases occurred in unimmunized children eligible for vaccination, and >25% of children in both measles-positive and -negative groups remained unimmunized for MMR 1-year post-outbreak. Our results suggest the need for novel, longitudinal vaccination strategies and increased awareness of the role of vitamin A.

Abstract
Lower respiratory tract infection (LRTI) remains a major cause of morbidity and mortality in children. Various organisms cause LRTI, including viruses, bacteria, fungi, and parasites, among others. Infections caused by 2 or more organisms also occur, sometimes enhancing the severity of the infection. Medical imaging helps confirm a diagnosis but also plays a role in the evaluation of acute and chronic sequelae. Medical imaging tests help evaluate underlying pathology in pediatric patients with recurrent or long-standing symptoms as well as the immunocompromised.

Abstract
Recognition of measles is crucial to prevent transmissions in the hospital settings. Little is known about the level of recognition of measles and possible causes of not recognising the disease by physicians in the post-vaccine era. We report on a measles outbreak in a paediatric hospital in Austria in January to February 2017 with strikingly high numbers of not recognised cases. The extent and course of the outbreak were assessed via retrospective case finding. Thirteen confirmed measles cases were identified, two with atypical clinical picture. Of eight cases with no known epidemiological link, only one was diagnosed immediately; four were recognised with delay and three only retrospectively. Eleven typical measles cases had four ‘unrecognised visits’ to the outpatient clinic and 28 on the ward. Two atypical cases had two ‘unrecognised visits’ to the outpatient clinic and 19 on the ward. Thirteen clinicians did not recognise typical measles (atypical cases not included). Twelve of 23 physicians involved had never encountered a patient with measles before. The direct and indirect costs related to the outbreak were calculated to be over EUR 80,000. Our findings suggest the need to establish regular training programmes about measles, including diagnostic pitfalls in paediatric hospitals.

Abstract
Despite the availability of a safe and effective vaccine, in 2018, around 350,000 measles cases were reported worldwide, which resulted in an estimate of 142,300 deaths from measles. Additionally, in 2017, global measles cases spiked, causing the death of 110,000 people, mostly children under the age of 5 years and immunocompromised adults. The increase in measles incidence is caused by the ongoing reduction of vaccination coverage. This event has triggered public and scientific interest. For this reason, we reviewed the pathophysiology of measles infection, focusing on mechanisms by which the virus spreads systemically through the host organism. By reaching the lymphocytes from the airways through a "trojan horse" strategy, measles induces an immunosuppression status. H and F glycoproteins, both expressed in the envelope, ensure attachment of the virus to host cells and spreading from one cell to another by binding to several receptors, as described in detail. The severity of the disease depends both on the age and underlying conditions of patients as well as the social and health context in which epidemics spread, and is often burdened by sequelae and complications that may occur several years after infection. Particular attention was paid to special groups that are more susceptible to severe or atypical measles. An overview of microbiology, symptoms, diagnosis, prevention, and treatment completes and enriches the review.

Measles-associated pneumonia and hepatitis during the measles outbreak of 2018. Int J Clin Pract 2020; 74:e13430.

Abstract
Background Between 2017 and 2018, Greece experienced a measles outbreak, affecting >3000 patients, most of which were unvaccinated. Measles-associated pneumonia (MAP) is the most common serious compilation of the disease, but very few recent reports regarding its presentation are available. Materials and Methods Between January and May 2018, 11 adult patients presented to our department with acute measles virus infection, hypoxia and findings on chest X-ray. Clinical, laboratory and radiological data were collected and assessed. Nine out of eleven patients had hypoxic respiratory failure. Other complications included hepatitis, cholestasis and myositis, which were observed in the majority of patients. All patients received supplementary oxygen administration, whereas five patients required continuous positive airway pressure ventilation. Scoring of the radiological examinations performed was most notable for the presence of reticular opacities and consolidations. Statistical analysis demonstrated a significant association between PaO2/FiO2 values and the presence of reticular opacities, with PaO2/FiO2 decreasing as the mean value of the reticular opacities score increased (P = .02). Conclusion To our knowledge, this is the first report demonstrating an association between PaO2/FiO2 values and the presence of reticular opacities in patients with MAP. MAP should be suspected in any patient presenting with acute onset hypoxaemia and a reticular pattern on radiological examination, especially in outbreak settings. What is known Measles infections are on the rise in Europe, with epidemics affecting several European countries, resulting from suboptimal immunisation. The most common serious complication of measles is pneumonia, which is more common in adult patients and can cause significant morbidity. It is the most common cause of death due to measles. What is new In this report, we present 11 adults with measles-associated pneumonia, who presented with the combination of acute measles virus infection, hypoxia and findings on chest X-ray. To our knowledge, this is the first report demonstrating an association between the severity of hypoxaemia and the presence of reticular opacities on chest imaging studies.

Abstract
Influenza, measles, SARS, MERS, and smallpox illnesses are caused by highly infectious viral pathogens that induce critical illness. These biologically diverse viruses enter and replicate within host cells triggering viral- and host-mediated damage that results in pneumonia and multiorgan failure in severe cases. Early case identification and strict infection control limit healthcare transmission. Vaccination allowed smallpox eradication and limits global measles and seasonal influenza mortality. While SARS-coronavirus (CoV) is no longer circulating, MERS-CoV and zoonotic influenza viruses, with pandemic potential, remain persistent threats. Supportive critical care is the mainstay of treatment for severe disease due to these viral infections.

Abstract
Based on measles surveillance in Shanghai, People's Republic of China, from 2006 to 2015, we found that measles virus isolates from 40 throat swab samples exhibited atypical cytopathic effects in Vero/hSLAM cells, which was found to be a result of coinfection with measles virus (MeV) and human herpes simplex virus type 1 (HSV-1). Serological and molecular approaches were used to confirm and characterize the coinfections in these patients. Among the 40 measles cases, measles-specific IgM was detected in 37 cases, while measles-specific IgG was detected in 27 cases. HSV-1-specific IgM and IgG were detected in 7 and 34 cases, respectively, suggesting that most of the MeV infections were primary, but that HSV-1 infection was due to the reactivation of latent virus in most cases. The titers of HSV-1 IgG in patients with either measles or measles-HSV-1 coinfection were significantly higher than those in the healthy group (P = 0.0026 and P < 0.0001, respectively); however, there was no significant difference in the titers of HSV-1 IgG in the MeV and MeV-HSV-1 coinfection patients (P = 0.105). Nucleic acids from MeV and HSV-1 were detected in 40 and 39 throat swabs, respectively. Twenty five MeV RNA sequences were genotyped, and all represented genotype H1, which is the endemic genotype in China. Sequences from the glycoprotein G gene of HSV-1 were used to classify the isolates into two distinct phylogenetic groups: 34 belonged to group A and 3 belonged to group B.

Abstract
BACKGROUND There are no recent descriptions of measles hospitalizations and complications in US children despite outbreaks within the past decade-including 2 in Minnesota (2011 and 2017). The objective of our study was to describe complications, hospital management and resource utilization for children hospitalized for measles at a US children's hospital. METHODS Retrospective case series of children (0-18 years of age) hospitalized for measles (observation/inpatient diagnosis code for measles) at Children's Minnesota, January 1, 2011, to September 1, 2017. Descriptive statistics were performed. RESULTS Thirty-three patients were included (7 from 2011 and 21 from 2017 outbreaks). Median age was 27 months (range, 6-95 months), 94% were Black or African American (73% Somali ethnicity), 88% had medical assistance and 91% were unvaccinated to measles. Poor feeding was a primary reason for admission (97%); additional complications included otitis media (42%), pneumonia (30%), tracheitis (6%) and keratitis (3%). Additional testing was common [chest radiographs (70%), blood cultures (64%), nonmeasles viral testing (42%)]. Seventy-three percent received antibiotics, 30% required oxygen and 21% received vitamin A. Median length of stay was 3.7 days (range, 1.1-26.2 days); 1 patient was readmitted. Median direct cost in 2017 was $5291 (interquartile range : $3907-$7519), and estimated total cost to the hospital for the 2017 outbreak was $1.3 million. CONCLUSIONS Clinicians should be aware of measles complications and treatment. Public and private health efforts should continue to focus on immunization, given significant implications of measles infections for patients and healthcare systems. Future studies may assess complications of measles across the United States as individual outbreaks often occur in specific populations, making generalization of results challenging.

Abstract
During a 2014 measles outbreak in Vietnam, postmortem pathologic examination of hospitalized children who died showed that adenovirus type 7 pneumonia was a contributory cause of death in children with measles-associated immune suppression. Adenovirus type 7 pneumonia should be recognized as a major cause of secondary infection after measles.

Abstract
France has recently witnessed a nationwide outbreak of measles. Data on severe forms of measles in adults are lacking. We sought to describe the epidemiologic, clinical, treatment, and prognostic aspects of the disease in adult patients who required admission to an intensive care unit (ICU). We performed a retrospective analysis of a cohort of 36 adults admitted to a total of 64 ICUs throughout France for complications of measles from January 1, 2009, to December 31, 2011. All cases of measles were confirmed by serologic testing and/or reverse transcription polymerase chain reaction.The cohort consisted of 21 male and 15 female patients, with a median age of 29.2 years (25th-75th interquartile range [IQR], 27.2-34.2 yr) and a median Simplified Acute Physiology Score (SAPS II) of 13 (IQR, 9-18). Among the 26 patients whose measles vaccination status was documented, none had received 2 injections. One patient had developed measles during childhood. Underlying comorbid conditions included chronic respiratory disease in 9 patients, immunosuppression in 7 patients, and obesity in 3 patients, while measles affected 5 pregnant women.Respiratory complications induced by measles infection led to ICU admission in 32 cases, and measles-related neurologic complications led to ICU admission in 2 cases. Two patients were admitted due to concurrent respiratory and neurologic complications.Bacterial superinfection of measles-related airway infection was suspected in 28 patients and was documented in 8. Four cases of community-acquired pneumonia, 6 cases of ventilator-associated pneumonia, 1 case of tracheobronchitis, and 2 cases of sinusitis were microbiologically substantiated.Of 11 patients who required mechanical ventilation, 9 developed acute respiratory distress syndrome (ARDS). Among the patients with ARDS, extraalveolar air leak complications occurred in 4 cases. Five patients died, all of whom were severely immunocompromised.On follow-up, 1 patient had severe chronic respiratory failure related to lung fibrosis, and 2 patients had mild lower limb paraparesis along with bladder dysfunction, both of which were ascribable to measles-induced encephalitis and myelitis. Among the 5 pregnant patients, the course of measles infection was uneventful, albeit 1 patient underwent emergent cesarean delivery because of fetal growth restriction.Measles is a disease with protean and potentially deceptive clinical manifestations, especially in the immunocompromised patient. Measles-associated pneumonitis and its complications, and less commonly postinfectious encephalomyelitis, are the main source of morbidity and mortality. In contrast with the usually benign course of the disease in immunocompetent patients, measles occurring in immunocompromised patients gives rise to lethal complications including ARDS, with or without bacterial superinfection. Other patients potentially at high risk for severe measles are young adults and pregnant women. Measles pneumonitis may predispose to air leak disease in patients using mechanical ventilation. To date, vaccination remains the most potent tool to control measles infection.

Abstract
For more than 30 years, vaccines have played an important part in pneumonia prevention. Recent advances have created opportunities for further improving child survival through prevention of childhood pneumonia by vaccination. Maximizing routine immunization with pertussis and measles vaccines, coupled with provision of a second opportunity for measles immunization, has rapidly reduced childhood deaths in low-income countries especially in sub-Saharan Africa. Vaccines against the two leading bacterial causes of child pneumonia deaths, Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae (pneumococcus), can further improve child survival by preventing about 1,075,000 child deaths per year. Both Hib and pneumococcal conjugate vaccines have proven safety and effectiveness for prevention of radiologically confirmed pneumonia in children, including in low-income and industrializing countries. Both are recommended by WHO for inclusion in national programmes, and, at sharply tiered prices, these vaccines generally meet international criteria of cost-effectiveness for low-income countries. Vaccines only target selected pneumonia pathogens and are less than 100% effective, so they must be complemented by curative care and other preventative strategies. As part of a comprehensive child survival package, the particular advantages of vaccines include the ability to reach a high proportion of all children, including those who are difficult to reach with curative health services, and the ability to rapidly scale up coverage with new vaccines. In this review, we discuss advances made in optimizing the use of established vaccines and the potential issues related to newer bacterial conjugate vaccines in reducing childhood pneumonia morbidity and mortality.

Abstract
Mycoplasma, Chlamydia and Legionella are the usual organisms considered to be the etiologic agents of 'atypical' pneumonia. Other microorganisms such as bacteria, viruses, parasites, fungi and mycobacteria can also present with atypical pneumonia manifestations. Outbreaks and isolated cases of respiratory viruses with atypical pneumonia presentations have been reported among immunocompetent and immunosuppressed patients. Severe infections due to these respiratory viruses alone or as a concomitant bacterial or viral infection have been observed. Additionally, in endemic areas, certain zoonotic infections may present as atypical pneumonia.

Abstract
OBJECTIVE To investigate whether prophylactic antibiotics can prevent complications of measles. DESIGN Community based, randomised, double blind, placebo controlled trial. SETTING Bandim Health Project study area in Bissau, Guinea-Bissau, west Africa. PARTICIPANTS 84 patients with measles during a measles epidemic in Bissau in 1998 (fewer than originally planned owing to interruption by war). INTERVENTIONS Sulfamethoxazole-trimethoprim (co-trimoxazole) or placebo for seven days. MAIN OUTCOME MEASURES Pneumonia and admission to hospital. Also weight change during the first month of infection, diarrhoea, severe fever, oral thrush, stomatitis, conjunctivitis, and otitis media. RESULTS The median age of the patients with measles was 5.4 (range 0.49-24.8) years. One of 46 participants who received co-trimoxazole developed pneumonia, in contrast to six of 38 participants who received placebo (odds ratio 0.08 (95% confidence interval 0 to 0.56), adjusted for age group). The number needed to treat was 7 (4 to 48). All three participants admitted to hospital had received placebo (P=0.09). The weight gain during the first month after inclusion was 15 (2-29) g/day in the placebo group and 32 (23-42) g/day in the co-trimoxazole group (P=0.04, adjusted for age group, weight for age at inclusion, measles vaccination status, and duration of disease). Significantly less conjunctivitis occurred among recipients of co-trimoxazole than placebo, as well as a non-significant tendency to less diarrhoea, severe fever, oral thrush, and stomatitis. Complications of otitis media were the same in the two groups. CONCLUSIONS The group that received prophylactic antibiotics had less pneumonia and conjunctivitis and had significantly higher weight gains in the month after inclusion. The results indicate that prophylactic antibiotics may have an important role in the management of measles infection in low income countries. TRIAL REGISTRATION Clinical trials NCT00168532.

Abstract
Pediatric acute respiratory distress syndrome (ARDS) is a severe lung injury caused by pneumonia, sepsis, and trauma. ARDS results from inflammation and pulmonary capillary leak causing major changes in lung architecture and function. It has a low incidence, but its severity and duration cause major morbidity, mortality, and use of resources. Any organism can cause ARDS. Susceptible populations develop the syndrome more often and have worse outcomes. Aggressive diagnosis and intensive treatment are essential to good outcomes in ARDS caused by infection. The prognosis for survival is good, but morbidity after the syndrome is a major burden.

Abstract
Forty years after effective vaccines were licensed, measles continues to cause death and severe disease in children worldwide. Complications from measles can occur in almost every organ system. Pneumonia, croup, and encephalitis are common causes of death; encephalitis is the most common cause of long-term sequelae. Measles remains a common cause of blindness in developing countries. Complication rates are higher in those <5 and >20 years old, although croup and otitis media are more common in those <2 years old and encephalitis in older children and adults. Complication rates are increased by immune deficiency disorders, malnutrition, vitamin A deficiency, intense exposures to measles, and lack of previous measles vaccination. Case-fatality rates have decreased with improvements in socioeconomic status in many countries but remain high in developing countries.

Abstract
Measles is the most frequent cause of vaccine-preventable childhood deaths. Infants younger than the recommended age for vaccination are susceptible to the disease, and in developing countries they have a high risk of complications and mortality. Vaccine coverage in excess of 95% interrupts endemic transmission of measles in many countries, but achievement of such coverage almost always requires coordinated supplementary mass vaccination campaigns. There are substantial health gains if countries improve measles vaccine coverage, irrespective of whether or not high coverage is achieved; these gains include much lower measles complication and case fatality rates, long-term interepidemic duration, and possibly non-specific improvements in survival of children. Investigation into the cost-effectiveness of different strategies for measles control, including mass campaigns, two-dose schedules, and young-infant doses, would help countries to formulate control policies appropriate to their setting. Pneumonia is the most common fatal complication associated with measles, and at least 50% of measles-related pneumonias are due to bacterial superinfection. WHO has developed standard case management programmes for measles, but there are several unresolved clinical issues, including optimum indications for antibiotic treatment, the importance of intravenous immunoglobulin, the role of viral coinfection, and the risk of tuberculosis after measles. The priority in worldwide efforts to control measles is to lend support to poor countries, helping them to increase vaccine coverage and sustain improvements to vaccination infrastructure, and to address technical issues with respect to optimum vaccination schedules. Measles represents a specific challenge, whereby partnerships between high-income and developing nations would reduce child mortality in developing countries; such partnerships are not without incentive for high-income countries, since without them imported measles cannot be prevented.

Abstract
We describe 6 patients who had bacteremic community-acquired pneumonia and unsuspected Legionella pneumophila coinfection. We reviewed case records of patients who were diagnosed as having a recent Legionella infection on the basis of either the presence of L. pneumophila serogroup 1 antigen in urine or a 4-fold increase in L. pneumophila antibody level and with a blood culture that yielded a bacterium other than L. pneumophila. Three patients were diagnosed with legionellosis on the basis of the presence of antigen in urine, and 3 were diagnosed on the basis of a 4-fold increase in antibody titer. Of these 6 patients, 4 were infected with Streptococcus pneumoniae, 1 with Streptococcus pyogenes, and 1 with Enterobacter cloacae. L. pneumophila infection in these patients may have predisposed them to concomitant bacteremia. Initial empiric antimicrobial therapy for patients who live in areas of endemicity and who are smokers should be treated with antimicrobial agents that have activity against pneumococcus and Legionella species.

Abstract
Most children presenting with pneumonia in the industrialised world will have a viral or 'atypical' organism. The clinical features of these 'atypical' pneumonias may be indistinguishable from bacterial pneumonia. New diagnostic techniques such as the polymerase chain reaction may help in diagnosis and choice of treatment, where appropriate. The pathological and clinical features of infection with each agent are discussed, together with their sequelae.

Abstract
There is evidence that acquired dysfunction of neutrophils, monocytes, or macrophages is an important cause of infection in patients with diabetes mellitus, renal or hepatic failure, alcoholism, autoimmune diseases, influenza or human immunodeficiency virus infection, burns, and trauma. Distinguishable mechanisms of acquired phagocyte dysfunction include inhibitory effects of metabolic disturbances (e.g., hyperglycemia, uremia), chemical toxins (e.g., ethanol), viral proteins on phagocyte activation, and pathologic activation of phagocytes in the circulation (e.g., after hemodialysis, burns, or cardiopulmonary bypass). Although the burden of morbidity and mortality resulting from acquired phagocyte dysfunction appears to be vast, research in this area has been hampered by the complexity of the underlying illnesses and by limitations of laboratory assays and clinical study methodology. Given the advent of improved assays of phagocyte functions and treatments that can enhance these functions, there is a pressing need for more prospective studies of acquired phagocyte dysfunction.
