Role of Chest Imaging in Viral Lung Diseases. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18126434. [PMID: 34198575 PMCID: PMC8296238 DOI: 10.3390/ijerph18126434] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 06/11/2021] [Accepted: 06/12/2021] [Indexed: 12/24/2022]
Abstract
The infection caused by novel beta-coronavirus (SARS-CoV-2) was officially declared a pandemic by the World Health Organization in March 2020. However, in the last 20 years, this has not been the only viral infection to cause respiratory tract infections leading to hundreds of thousands of deaths worldwide, referring in particular to severe acute respiratory syndrome (SARS), influenza H1N1 and Middle East respiratory syndrome (MERS). Although in this pandemic period SARS-CoV-2 infection should be the first diagnosis to exclude, many other viruses can cause pulmonary manifestations and have to be recognized. Through the description of the main radiological patterns, radiologists can suggest the diagnosis of viral pneumonia, also combining information from clinical and laboratory data.

Immunity and Vaccination Against Measles, Mumps, and Rubella in Adult Allogeneic Hematopoietic Stem Cell Transplant Recipients. Transplant Cell Ther 2021; 27:436.e1-436.e8. [PMID: 33775586 DOI: 10.1016/j.jtct.2021.02.027] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 02/21/2021] [Accepted: 02/21/2021] [Indexed: 11/30/2022]
Abstract
Large outbreaks of measles or rubella occasionally occur around the world, and measles infection can be severe and even fatal in transplant patients. However, limited data are available on immunity to measles, mumps, and rubella (MMR) in adult patients after allogeneic stem cell transplantation (allo-HCT). The aim of this study was to evaluate the immune status against MMR and the effects of vaccination against MMR in adult patients after allo-HCT. A total of 135 adult patients who were alive without relapse and new malignancy at 2 years after allo-HCT were included in this study. We measured IgG antibody to MMR before allo-HCT and annually thereafter. The probabilities of being seropositive to measles, mumps or rubella after allo-HCT were estimated according to the Kaplan-Meier method and compared among groups with the log-rank test. The probability of being seropositive at 2 years after allo-HCT in patients who were seropositive before allo-HCT was 60.6% for measles, 39.7% for mumps, and 52.2% for rubella. History of chronic graft-versus-host disease tended to be a risk factor for the loss of immunity against measles (hazard ratio [HR] 1.69, P = .064) and rubella (HR 1.75, P = .056). To predict the loss of immunity against MMR at 2 years after allo-HCT, we defined the following cutoff values for the IgG index before HCT: 18.2 for measles, 5.3 for mumps, and 21.4 for rubella using a receiver-operating characteristics curve. The lower-IgG groups experienced a significant loss of seropositivity at 2 years (39% versus 82% for measles, P < .001; 13% versus 59% for mumps, P < .001; and 33% versus 90% for rubella, P < .001). After this loss of immunity, 25 patients received a single vaccination against MMR. The seroconversion rates were 64%, 36%, and 72% for measles, mumps, and rubella, respectively. Loss of immunity to MMR commonly occurs in the first several years after transplantation. In the patients who lose the immunity, the seroconversion rate after 1 dose of MMR vaccine given at ≥2 years after transplantation is suboptimal.

Abstract
DPC, which is an acronym for “Diagnosis Procedure Combination,” is a patient classification method developed in Japan for inpatients in the acute phase of illness. It was developed as a measuring tool intended to make acute inpatient care transparent, aiming at standardization of Japanese medical care, as well as evaluation and improvement of its quality. Subsequently, this classification method came to be used in the Japanese medical service reimbursement system for acute inpatient care and appropriate allocation of medical resources. Furthermore, it has recently contributed to the development and maintenance of an appropriate medical care provision system at a regional level, which is accomplished based on DPC data used for patient classification. In this paper, we first provide an overview of DPC. Next, we will look back at over 15 years of DPC history; in particular, we will explore how DPC has been refined to become an appropriate medical service reimbursement system. Finally, we will introduce an outline of DPC-related research, starting with research using DPC data.

Measles in pregnant women: A systematic review of clinical outcomes and a meta-analysis of antibodies seroprevalence. J Infect 2019; 80:152-160. [PMID: 31891729 DOI: 10.1016/j.jinf.2019.12.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 12/18/2019] [Accepted: 12/23/2019] [Indexed: 12/22/2022]
Abstract
OBJECTIVES Pregnant women represent a category at high risk of severe measles infection, that negatively affects the fetus as well. A systematic review of clinical outcomes of measles infection in gravid subjects and a meta-analysis of antibodies prevalence among pregnant women was conducted. METHODS MEDLINE and EMBASE databases were searched up to 18 June 2018. The screening focused on: (i) articles describing the outcome of measles in pregnancy, synthesized in a descriptive fashion; (ii) articles addressing the measles seroprevalence in cohorts of gravid women, analysed quantitatively. RESULTS Twenty-nine articles met inclusion criteria. A total of 420 cases of measles in gravid subjects were described, from 1941 to 2012. Among women, 18 deaths (4.3%) occurred, and the most frequent complication was pneumonia (75/420, 17.9%). Prematurity was the most important complication concerning fetal outcomes (55 out of 410 cases with available data, 13.4%). The random-effects pooled seroprevalence of measles in 20,546 gravid women worldwide was 89.3% (95% CI: 87.3-91.1%), that decreased, although not in a statistically significant way, over time (p = 0.54). CONCLUSIONS Measles infection in pregnancy is dangerous both for the mother and the foetus. Antibody seroprevalence among gravid women on a global scale is lower than the herd immunity threshold.

In-hospital mortality associated with transcatheter arterial embolization for treatment of hepatocellular carcinoma in patients on hemodialysis for end stage renal disease: a matched-pair cohort study using a nationwide database. BJR Open 2019; 1:20190004. [PMID: 33178938 PMCID: PMC7592431 DOI: 10.1259/bjro.20190004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2018] [Revised: 04/25/2019] [Accepted: 05/30/2019] [Indexed: 02/06/2023] Open
Abstract
Objectives: No previous study has evaluated the risks associated with transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma in patients on hemodialysis (HD) for end stage renal disease (ESRD), because invasive treatment is rarely performed for such patients. We used a nationwide database to investigate in-hospital mortality and complication rates following TACE in patients on HD for ESRD. Methods: Using the Japanese Diagnosis Procedure Combination database, we enrolled patients on HD for ESRD who underwent TACE for hepatocellular carcinoma. For each patient, we randomly selected up to four non-dialyzed patients using a matched-pair sampling method based on the patient’s age, sex, treatment hospital, and treatment year. In-hospital mortality and complication rates were compared between dialyzed and non-dialyzed patients following TACE. Results: We compared matched pairs of 1551 dialyzed and 5585 non-dialyzed patients. Although the complication rate did not differ between the dialyzed and non-dialyzed ESRD patients [5.7% vs 5.8%, respectively; odds ratio, 0.99; 95% confidence interval (0.79–1.23); p = 0.90], the in-hospital mortality rate was significantly higher in dialyzed ESRD patients than in non-dialyzed patients [2.2% vs 0.97%, respectively; odds ratio, 2.21; 95% confidence interval (1.44–3.40); p < 0.001]. Among the dialyzed patients, the mortality rate was not significantly associated with sex, age, Charlson comorbidity index, or hospital volume. Conclusions: The in-hospital mortality rate following TACE was 2.2 % and was significantly higher in dialyzed than in non-dialyzed ESRD patients. The indications for TACE in HD-dependent patients should be considered carefully with respect to the therapeutic benefits vs risks. Advances in knowledge: In hospital mortality rate following TACE in dialyzed patients was more than twice compared to non-dialyzed patients. Post-procedural complication following TAE in ESRD onHD patients was 5.7%, and did not differ from that in non dialyzed patients.

Abstract
BACKGROUND Measles virus can cause lower respiratory tract infection, so that chest radiography is necessary to investigate lung involvement in patients with respiratory distress. PURPOSE To assess measles pneumonia imaging during the measles outbreak occurred in 2016-2017 in Italy. MATERIAL AND METHODS We retrospectively observed adult patients with a serological diagnosis of measles, who underwent chest-X rays for suspected pneumonia. If a normal radiography resulted, the patient underwent unenhanced CT. A CT post processing software package was used for an additional quantitative lung and airway involvement analysis . RESULTS Among 290 patients affected by measles, 150 underwent chest-X ray. Traditional imaging allowed the pneumonia diagnosis in 114 patients (76%). The most frequent abnormality at chest X-rays was bronchial wall thickening, observed in 88.5% of the cases; radiological findings are faint in the 25% of the cases (29/114 patients). In nine subjects with a normal chest X-ray, unenhanced CT with a quantitative analysis was performed, and depicted features consistent with constrictive bronchiolitis. CONCLUSION Measles may produce bronchiolitis and pneumonia. In the cases in which involvement of pulmonary parenchyma is not sufficient to result in radiological abnormalities, CT used with a dedicated postprocessing software package, provides an accurate lungs and airways analysis, also determining the percentage of lung involvement.

Abstract
BACKGROUND AND AIM Because of the rarity of invasive treatment for hepatocellular carcinoma (HCC) in patients on hemodialysis (HD) for end-stage renal disease (ESRD), the risks associated with radiofrequency ablation (RFA) in such patients remain uncertain. We used a nationwide database to investigate in-hospital mortality and hemorrhagic complications following RFA in patients on HD for ESRD. METHODS Using the Japanese Diagnosis Procedure Combination database, we enrolled patients on HD for ESRD who underwent RFA for HCC. For each patient, we randomly selected up to four non-dialyzed patients using a matched-pair sampling method based on patient age, sex, treatment hospital, and treatment year. In-hospital mortality and hemorrhagic complications were compared between dialyzed and non-dialyzed patients following RFA. RESULTS We compared matched-pair samples of 437 dialyzed and 1345 non-dialyzed patients. In patients on HD for ESRD, mortality was significantly lower in those aged ≤70 years than in older patients (P = 0.02). In-hospital mortality was significantly higher in dialyzed ESRD patients than in non-dialyzed patients (1.1% vs 0.15%, respectively; odds ratio = 7.77, P < 0.001). Hemorrhagic complications differed significantly between dialyzed ESRD patients and non-dialyzed patients (3.4% vs 0.87%, respectively; odds ratio = 4.75, P < 0.001). CONCLUSIONS In-hospital mortality following RFA was higher in dialyzed ESRD patients than in non-dialyzed patients. The indications for RFA in dialysis-dependent patients should be considered carefully. Patient age may be a useful indicator when considering RFA for HCC in patients on HD for ESRD.

Abstract
BACKGROUND The Lazio region is one of the Italian regions where sustained measles transmission continues to occur. We investigated measles cases reported by the emergency department (ED) of the largest pediatric hospital in Italy, located in Lazio. METHODS We reviewed clinical records of all measles cases from 0 to 18 years of age evaluated in the ED in 2008-2013. We compared demographic and clinical characteristics of patients admitted to the inpatient setting with those of patients discharged home to assess possible determinants of hospital admission. RESULTS Of 248 patients with measles evaluated in the ED, 113 (45.6%) were admitted as inpatients. The number of measles cases peaked in 2011 (N = 122; 49.2%), when epidemics were reported in Lazio. Median age was 2.7 years (range: 21 days to 17.9 years), and 31 patients (13%) had an underlying chronic illness. The strongest independent predictor of hospitalization was having an underlying chronic illness [adjusted odd ratio (OR): 9.87; 95% confidence interval: 3.13-31.13]. Other factors independently and significantly associated with higher risk of hospitalization were taking medications at the time of ED visit, being younger than 1 year of age and having altered liver enzyme values. Eighty-five percent of children >15 months of age who were hospitalized were not vaccinated. One hundred six hospitalized children (94%) had at least 1 measles complication; 1 child required intensive care for respiratory insufficiency. CONCLUSIONS Hospitalizations of children with measles continue to occur in European areas where elimination has not been achieved. Children with chronic diseases represent a vulnerable population that is at higher risk of hospitalization.

Abstract
Background Radiofrequency ablation (RFA) is a minimally invasive treatment for hepatocellular carcinoma (HCC). There is increasing evidence of an association between increasing hospital volume and lower postoperative mortality for many surgical procedures, but this is difficult to establish with minimally invasive treatments, where postoperative mortality is low. The aim of this study was to investigate the relationship between hospital volume and in-hospital mortality following RFA using a Japanese nationwide database. Methods Data from the Diagnostic Procedure Combination database were analysed from 1 July 2010 to 31 March 2012. Multivariable logistic regression was used to analyse the relationship between hospital volume and in-hospital mortality following RFA, with adjustment for patient background. Results Some 36 675 patients with HCC were identified in the database. The overall in-hospital mortality rate from RFA was 0·31 per cent. In-hospital mortality was significantly higher in low-volume than high-volume hospitals (odds ratio 2·57, 95 per cent c.i. 1·61 to 4·09; P < 0·001). Higher in-hospital mortality was significantly associated with older age and a higher Charlson Co-morbidity Index score. Conclusion RFA for HCC was associated with acceptably low mortality in Japan, but in-hospital mortality following RFA was affected by hospital procedural volume.

Abstract
AIM We aimed to develop a model for predicting in-hospital mortality of cirrhotic patients following major surgical procedures using a large sample of patients derived from a Japanese nationwide administrative database. METHODS We enrolled 2197 cirrhotic patients who underwent elective (n = 1973) or emergency (n = 224) surgery. We analyzed the risk factors for postoperative mortality and established a scoring system for predicting postoperative mortality in cirrhotic patients using a split-sample method. RESULTS In-hospital mortality rates following elective or emergency surgery were 4.7% and 20.5%, respectively. In multivariate analysis, patient age, Child-Pugh (CP) class, Charlson Comorbidity Index (CCI), and duration of anesthesia in elective surgery were significantly associated with in-hospital mortality. In emergency surgery, CP class and duration of anesthesia were significant factors. Based on multivariate analysis in the training set (n = 987), the Adequate Operative Treatment for Liver Cirrhosis (ADOPT-LC) score that used patient age, CP class, CCI, and duration of anesthesia to predict in-hospital mortality following elective surgery was developed. This scoring system was validated in the testing set (n = 986) and produced an area under the curve of 0.881. We also developed iOS/Android apps to calculate ADOPT-LC scores to allow easy access to the current evidence in daily clinical practice. CONCLUSION Patient age, CP class, CCI, and duration of anesthesia were identified as important risk factors for predicting postoperative mortality in cirrhotic patients. The ADOPT-LC score effectively predicts in-hospital mortality following elective surgery and may assist decisions regarding surgical procedures in cirrhotic patients based on a quantitative risk assessment.

Abstract
National and global health policymakers require good information about the costs and benefits of their investments in measles and rubella immunization programs. Building on our review of the existing measles and rubella health economics literature, we develop inputs for use in regional and global models of the expected future benefits and costs of vaccination, treatment, surveillance, and other global coordination activities. Given diversity in the world and limited data, we characterize the costs for countries according to the 2013 World Bank income levels using 2013 U.S. dollars (2013$US). We estimate that routine immunization and supplemental immunization activities will cost governments and donors over 2013$US 2.3 billion per year for the foreseeable future, with high-income countries accounting for 55% of the costs, to vaccinate global birth cohorts of approximately 134 million surviving infants and to protect the global population of over 7 billion people. We find significantly higher costs and health consequences of measles or rubella disease than with vaccine use, with the expected disability-adjusted life year (DALY) loss for case of disease generally at least 100 times the loss per vaccine dose. To support estimates of the economic benefits of investments in measles and/or rubella elimination or control, we characterize the probabilities of various sequelae of measles and rubella infections and vaccine adverse events, the DALY inputs for health outcomes, and the associated treatment costs. Managing measles and rubella to achieve the existing and future regional measles and rubella goals and the objectives of the Global Vaccine Action Plan will require an ongoing commitment of financial resources that will prevent adverse health outcomes and save the associated treatment costs.

Abstract
From January 1 to April 3, 2015, 159 people from 18 states and the District of Columbia were reported as having measles. Most cases are part of an outbreak linked to a California amusement park. Because measles was eliminated in the United States in 2000, most U.S. clinicians are unfamiliar with the condition. We reviewed information on the current outbreak, measles manifestations, diagnostic methods, treatment, and infection-control recommendations. To identify information on measles and pregnancy, we reviewed reports with 20 or more measles cases during pregnancy that included data on effects on pregnant women or pregnancy outcomes. These reports were identified through MEDLINE from inception through February 2015 using the following strategy: (((pregnan*) AND measles) AND English[Language]) NOT review[Publication Type]. Reference lists also were reviewed to identify additional articles. Pregnant women infected with measles are more likely to be hospitalized, develop pneumonia, and die than nonpregnant women. Adverse pregnancy outcomes, including pregnancy loss, preterm birth, and low birth weight, are associated with maternal measles; however, the risk of congenital defects does not appear to be increased. No antiviral therapy is available; treatment is supportive. Early identification of possible cases is needed so that appropriate infection control can be instituted promptly. The recent measles outbreak highlights the role that obstetric health care providers play in vaccine-preventable illnesses; obstetrician-gynecologists should ensure that patients are up to date on all vaccines, including measles-containing vaccines, and should recommend and ideally offer a measles-containing vaccine to women without evidence of measles immunity before or after pregnancy.

Abstract
AIM Gastroesophageal variceal hemorrhage is an important complication of cirrhosis. We investigated the in-hospital mortality and its risk factors after variceal hemorrhage in a large sample population, using a nationwide Japanese database. METHODS Data on the patients with variceal hemorrhage were collected for a total of 39 months from a nationwide administrative database covering approximately 1000 hospitals in Japan. The risk factors for fatal outcome after variceal hemorrhage were analyzed with receiver-operator curves (ROC) and univariate and multivariate logistic regression. Comorbidities were assessed with the Charlson Comorbidity Index. RESULTS We identified 9987 patients with variceal hemorrhage from a total of 20.3 million inpatients in the database. The median age was 63 years and 68.8% were male. The overall in-hospital mortality was 16.8% (1676 cases). In univariate analysis, Child-Pugh class was the strongest predictor; the area under the ROC of Child-Pugh score for predicting in-hospital mortality was 0.802. In multivariate analysis, increased in-hospital mortality was significantly associated with male sex (vs female: odds ratio [OR] = 1.19, P = 0.01), older age, Child-Pugh class B or C (B vs A: OR = 2.80, P < 0.001; C vs A: OR = 20.1, P < 0.001) and higher Charlson Comorbidity Index (≥6 vs ≤5; OR = 1.29, P < 0.001). CONCLUSION In spite of recent advances in the treatment of variceal hemorrhage, the in-hospital mortality remained as high as 16%. Poor liver function was the most important predictor, suggesting that liver failure after variceal hemorrhage might have been the cause of death.

Abstract
BACKGROUND Accurate data on the incidence of acute liver disease (ALD) is lacking in most countries. We investigated the incidence of ALD-related admission in Japan using a large sample in a nationwide Japanese database. METHODS Data from the Diagnosis Procedure Combination database were analyzed for 1 July to 31 December 2007-2010. Patient characteristics, in-hospital mortality, and clinical practices, including drugs and procedures during hospitalization, were analyzed. RESULTS We identified 10509 patients with ALD from a total of 11.61 million inpatients in the database. The median age was 53 years and 54.7 % were male. The annual incidence of ALD-related hospital admission was estimated to be 131.1 cases/1 million people. The overall mortality rate was 5.9 % (622 cases). The infant (0-3 years), child (4-18 years), and adult in-hospital mortality rates were 2.7 % (7/261), 1.0 % (5/494), and 6.3 % (610/9754), respectively. The infant and child mortality rates were significantly lower than the adult mortality rate (Chi square test: P = 0.03 and P < 0.001, respectively). Hepatitis A virus- and hepatitis C virus-induced ALD had favorable outcomes, with in-hospital mortality rates of approximately 2 %. Plasma exchange and continuous hemodiafiltration were performed in 5.3 % (556 cases) and 3.4 % (360 cases) of all ALD cases, respectively. CONCLUSIONS In-hospital mortality of ALD in Japan was acceptably low, and was affected by the etiology and patient background characteristics. The present study adds important information on the incidence and prognosis of ALD in Japan. Improvement of public health surveillance systems is necessary for population-based patient monitoring.

Abstract
Although few measles cases were reported in France during 2006 and 2007, suggesting the country might have been close to eliminating the disease, a dramatic outbreak of >20,000 cases occurred during 2008–2011. Adolescents and young adults accounted for more than half of cases; median patient age increased from 12 to 16 years during the outbreak. The highest incidence rate was observed in children <1 year of age, reaching 135 cases/100,000 infants during the last epidemic wave. Almost 5,000 patients were hospitalized, including 1,023 for severe pneumonia and 27 for encephalitis/myelitis; 10 patients died. More than 80% of the cases during this period occurred in unvaccinated persons, reflecting heterogeneous vaccination coverage, where pockets of susceptible persons still remain. Although vaccine coverage among children improved, convincing susceptible young adults to get vaccinated remains a critical issue if the target to eliminate the disease by 2015 is to be met.

Abstract
From January 2008 to May 2012, over 22,000 cases of measles were reported in France. The highest incidence rate was observed in children below one year of age. Over 50% of cases were reported in young adults. Almost 5,000 patients were hospitalised including 1,023 with severe pneumonia, 27 with encephalitis and/or myelitis : 10 died. This situation is linked to insufficient and heterogeneous vaccination coverage with pockets of susceptible people allowing virus circulation. Although the vaccine coverage in children has now improved for both doses, the issue of convincing young susceptible adults to catch up for measles vaccination remains critical, if the elimination target is to be met, and in order to protect the most vulnerable population unable to benefit from this vaccination (children below 1 year, immunodeficient people, pregnant women).

Abstract
BACKGROUND Reported mortalities and morbidities of therapeutic procedures for liver tumors vary between studies, because of different designs and small sample sizes. We investigated the mortalities and complication rates for hepatectomy, radiofrequency ablation (RFA), and trans-catheter arterial embolization (TAE) for hepatocellular carcinoma (HCC) in a large sample, using a nationwide Japanese database (the Diagnosis Procedure Combination database). METHODS Data from the Diagnosis Procedure Combination database were analyzed for July 1 to December 31, 2007 and the same period in 2008. We identified 54,145 patients with HCC who underwent hepatectomy (n = 5,270), RFA (n = 11,688), or TAE (n = 37,187). In-hospital mortality and morbidity were analyzed for each procedure. The relationships between mortality and factors including patient characteristics and procedural backgrounds were assessed. RESULTS In-hospital mortalities associated with hepatectomy, RFA, and TAE were 2.6 % [95 % confidence interval (CI) 2.2-3.1], 0.3 % (0.2-0.4), and 1.0 % (0.9-1.1), and post-procedural complication rates were 14.5 % (13.5-15.5), 4.5 % (4.2-4.9), and 4.5 % (4.3-4.7), respectively. Increased mortality following hepatectomy was significantly associated with older age, extended lobectomy (vs. partial hepatectomy; odds ratio [OR] 3.80, p < 0.001), lower hospital volume (OR 2.74, p < 0.001), and renal comorbidity (OR 3.01, p = 0.02). Older age and cardiac comorbidity (OR 5.14, p = 0.001) were significantly associated with RFA-related mortality, and lower hospital volume was significantly associated with TAE-related mortality (OR 1.60, p < 0.001). CONCLUSIONS Mortalities and morbidities associated with therapeutic procedures for liver tumors were acceptably low in Japan, but were affected by patient and institutional characteristics.

Abstract
BACKGROUND/AIMS Because of high vaccination rates, population immunity against measles increased in the western world. Nevertheless, outbreaks are still observed. The aim of this article is to document and describe the natural course of dermatological manifestations and compare it with the literature. METHODS After detecting a measles index case, the dermatological onset of the disease in the non-vaccinated siblings was prospectively monitored and documented with a digital camera. RESULTS Our findings show that dermatological symptoms are only limited consistently from one case to another and described heterogeneously in the literature as well. CONCLUSION Dermatological manifestations do not seem conclusive in our clinical data set as well as in the literature. Especially the exact onset of the Koplik spots should be further explored in detail. In future, a larger population should be observed and clinical diagnostics for measles defined.
