Measles immunity in an Italian teaching hospital.

BACKGROUND: Healthcare workers (HCWs) have an increased exposure risk to measles, which can put them, their patients and their relatives at risk of infection. In Italy, 4617 cases of measles were reported in 2017; 302 involving HCWs. According to the Italian National Immunization and Prevention Plan, all HCWs should have demonstrable evidence of immunity to measles. AIMS: To evaluate measles immunization status in HCWs at a large Italian teaching hospital. METHODS: We analysed clinical records and measles-specific IgG antibody titres of HCWs undergoing occupational health surveillance between 1 January and 31 August 2017. RESULTS: Among the 1532 HCWs (mean age 32.7 ± 10.4 years) included in the study, 87% (1328) had protective antibody titres. The proportion of protective titres was highest in those born before 1982. No significant gender differences in mean measles-specific IgG antibody titres were detected. CONCLUSIONS: Our study shows non-protective measles IgG antibody titres in a substantial percentage of HCWs, especially those born in the 1980s and 1990s. Due to the increased risk of measles transmission in the hospital environment, increased prevention strategies are required, including rigorous screening and prompt vaccination of non-immune workers.

Metastatic volume: an old oncologic concept and a new prognostic factor for stage IV melanoma patients.

BACKGROUND: The last melanoma staging system of the 2009 American Joint Committee on Cancer takes into account, for stage IV disease, the serum levels of lactate dehydrogenase (LDH) and the site of distant metastases. OBJECTIVE: Our aim was to compare the significance of metastatic volume, as evaluated at the time of stage IV melanoma diagnosis, with other clinical predictors of prognosis. METHODS: We conducted a retrospective multicentric study. To establish which variables were statistically correlated both with death and survival time, contingency tables were evaluated. The overall survival curves were compared using the Kaplan-Meier method. RESULTS: Metastatic volume and number of affected organs were statistically related to death. In detail, patients with a metastatic volume >15 cm(3) had a worse prognosis than those with a volume lower than this value (survival probability at 60 months: 6.8 vs. 40.9%, respectively). The Kaplan-Meier method confirmed that survival time was significantly related to the site(s) of metastases, to elevated LDH serum levels and to melanoma stage according to the latest system. CONCLUSION: Our results suggest that metastatic volume may be considered as a useful prognostic factor for survival among melanoma patients.

Management and follow-up of a patient with Familial Atypical Multiple Mole-Melanoma (FAMMM) Syndrome.

INTRODUCTION: Familial Atypical Multiple Mole-Melanoma Syndrome (FAMMM) is an autosomal dominant genodermatosis characterized by the presence of a high number of dysplastic nevi and family history of melanoma or pancreatic cancer. Melanomas in FAMMM patients tend to occur at a younger age, although they are clinically similar to sporadic melanomas in terms of overall survival. CASE REPORT: A 45 year-old woman with a family history of melanoma, a type II phototype and numerous (>100) nevi was admitted to our Department of Dermatology and Plastic Surgery. Over the past years, the patient underwent several surgical operations to remove pigmented lesions and two are dysplastic nevi. Since 1995, she underwent surgery to remove four melanomas. She is followed for skin examinations including dermoscopy. CONCLUSION: Identifying high-risk patients for melanoma represents a primary objective for the specialists that are involved in the management of this disease, especially in order to enact all the necessary surveillance and follow-up strategies.
