Epidemiology of Mucormycosis in Greece; Results from a Nationwide Prospective Survey and Published Case Reports.

Mucormycosis has emerged as a group of severe infections mainly in immunocompromised patients. We analysed the epidemiology of mucormycosis in Greece in a multicentre, nationwide prospective survey of patients of all ages, during 2005-2022. A total of 108 cases were recorded. The annual incidence declined after 2009 and appeared stable thereafter, at 0.54 cases/million population. The most common forms were rhinocerebral (51.8%), cutaneous (32.4%), and pulmonary (11.1%). Main underlying conditions were haematologic malignancy/neutropenia (29.9%), haematopoietic stem cell transplantation (4.7%), diabetes mellitus (DM) (15.9%), other immunodeficiencies (23.4%), while 22.4% of cases involved immunocompetent individuals with cutaneous/soft-tissue infections after motor vehicle accident, surgical/iatrogenic trauma, burns, and injuries associated with natural disasters. Additionally, DM or steroid-induced DM was reported as a comorbidity in 21.5% of cases with various main conditions. Rhizopus (mostly R. arrhizus) predominated (67.1%), followed by Lichtheimia (8.5%) and Mucor (6.1%). Antifungal treatment consisted mainly of liposomal amphotericin B (86.3%), median dose 7 mg/kg/day, range 3-10 mg/kg/day, with or without posaconazole. Crude mortality was 62.8% during 2005-2008 but decreased significantly after 2009, at 34.9% (p = 0.02), with four times fewer haematological cases, fewer iatrogenic infections, and fewer cases with advanced rhinocerebral form. The increased DM prevalence should alert clinicians for timely diagnosis of mucormycosis in this patient population.

Congenital asymmetric crying facies and agenesis of corpus callosum.

Although association of congenital asymmetric crying facies (CACF) with major congenital anomalies of central nervous system (CNS) has been described, brain magnetic resonance imaging (MRI) studies have not been reported. Two children who had CACF associated with agenesis of corpus callosum (ACC) diagnosed by MRI are described. Neurofibromatosis type 1 (NF-1) was diagnosed in one case. Both patients had developmental delay. To the best of our knowledge, only one previous case with CACF associated with ACC has been reported, but our cases are the first cases reported with the characteristic findings of ACC on MRI. Although café-au-lait spots have been described in previous cases, the coexistence of CACF and NF-1 has not previously been reported. Although these associations may be coincidental, clinicians should be aware of the potential link between these entities. Furthermore, these findings emphasize the importance of MRI studies for detecting brain anomalies in cases with CACF and suspected CNS involvement.

Congenital microcephaly in two infants with the factor V Leiden mutation.

Two infants with congenital microcephaly associated with the factor V Leiden mutation are described. In both cases, brain magnetic resonance imaging (MRI) revealed cerebral atrophy and porencephalic cystic lesions, which were probably attributable to prenatal cerebral vascular events. These findings suggest that assessment for this mutation is an important part of the evaluation of infants with unexplained congenital microcephaly, especially in cases with infarcts and/or porencephalic cysts on brain MRI.
