ABSTRACT
In the Mediterranean basin, one of the most important agents of myiasis is Oestrus ovis Linnaeus 1758 (Diptera, Oestridae). Herein, we report a rare case of nasal myiasis with a secondary infection complication in a patient from northern Italy who had been visiting Corsica. A healthy, 39-year-old Italian woman spent 2 weeks of vacation in Corsica in June 2018. During her stay, she suddenly felt a foreign body inside her nose, followed by cough, pain, burning at the pharyngeal level, cephalalgia, and nasal congestion with secretions from the nostrils. The clinical examination showed a hyperemic and irritated mucosa and endoscopic examination of the patient's nose and right maxillary sinus revealed three tiny mobile larvae, morphologically and molecular identified as L1 instar larvae of Oestrus ovis. The patient's infestation was probably imported from Corsica, as Mediterranean islands are ideal geographical areas for the development of O. ovis, and the timing of infestation match with the period of O. ovis larviposition. Although rhinomyiasis is rare, it should be considered in people returning from abroad presenting with an acute-onset and foreign body sensation in the nose.
ABSTRACT
OBJECTIVE: Reduction of maternal mortality is a major priority in the public health domain. One of the main causes of maternal mortality is postpartum haemorrhage. Because economic pressures favour the use of less expensive strategies, it is becoming now critical to know exactly the cost of the surgical procedures involved in the treatment of postpartum haemorrhage, in order to provide future guidelines in Implementing reforms in hospital. MATERIALS AND METHODS: Evaluation was made on multiple data collected in the Gynecology-Obstetrics and Central Sterile Supplies departments of a tertiary care Hospital. Analysis of the production costs was made based on the actual costs. The receipts were figured on the basis of applicable reimbursement in France in 2005, taking into account the financial decisions of the producers. RESULTS: From January 2004 to December 2005, 262 patients were treated for postpartum hemorrhage and patients files were available for review in 255 cases. Of these, surgery was performed in 52 cases. The costs of surgery in the postpartum care ranged from 275.04 euro per manual exploration of the uterine cavity (n=8), 302.48 euro per exploration with valve (n=26), 601.55 euro per vascular ligation (n=3), 725.53 euro per vaginal packing or unpacking (n=10) to 875.06 euro per hysterectomy (n=5). Cleaning and sterilizing of surgical instruments represented a substantial burden, ranging from 7.5% to 11.4% of the total cost of surgery. DISCUSSION AND CONCLUSION: The costs of surgery for postpartum haemorrhage have been calculated to provide future guidelines for the directions and follow-up of these activities in light of the T2A-EPRD and poles of activity. The actual costs could be used to determine the bases of one or more French DRGs (PMSI) "postpartum hemorrhage" evolution.

OBJECTIVE: To determine the possible association between intraventricular hemorrhage (IVH) in very premature infants and calcium-channel blockers used as tocolytics. MATERIALS AND METHODS: We performed a case-control study (from October 1999 to December 2002) including 51 premature infants under 30 weeks with IVH (all grade) and 112 premature infants under 30 weeks without IVH. In this study only premature infants issued from spontaneous prematurity were included. The exposure frequency to calcium-channel blockers and to other tocolytics were compared between the two groups by univariate analysis and by logistic regression analysis. RESULTS: Calcium-channel blockers were used in monotherapy before birth in 16% of infants without IVH and in 20% of infants with IVH (P=0.55). An exposure to a bitherapy or a tritherapy with a calcium-channel blocker and one or several other tocolytics has been found in 43% of infants with IVH and in 26% of infants without IVH (P<0.05). However this association disappears after adjustment for gestational age. CONCLUSION: We did not find a significant association between calcium-channel blockers used as tocolytics and an increased risk of intraventricular hemorrhage in premature infants less than 30 weeks.

IS1245-based restriction fragment length polymorphism (RFLP) analysis has been proposed recently for molecular typing of Mycobacterium avium isolates. As there is no standardised method with respect to the optimal restriction enzyme, three restriction endonucleases were tested for analysis of 17 human isolates. The restriction endonucleases, selected on the basis of the physical maps of IS1245 and of the highly homologous IS1311, were BsaAI, that cleaves IS1245, PvuII, that cleaves IS1311, and NruI, that cleaves both IS1245 and IS1311. All the restriction endonucleases yielded polymorphic and complex RFLP patterns. However, BsaAI- and NruI-generated bands were more evenly distributed and easier to detect than PvuII-generated bands, most of which clustered in a narrow zone of the fingerprint. In some cases, DNA digestion with BsaAI or NruI yielded probe-specific restriction fragments of molecular size lower than expected. Moreover, digestion with NruI, which was expected to generate the highest numbers of bands in all the isolates, yielded fewer bands than were obtained with BsaAI or PvuII in 14 and 5 isolates, respectively. These findings might suggest the existence of unidentified IS1245-related insertion element(s) in M. avium isolates. Computer analysis of the IS1245-based RFLP patterns of M. avium isolates showed that the restriction endonucleases were capable, although with minor differences, of defining distinct banding patterns and clusters of identical or highly related isolates, thus confirming IS1245-based RFLP analysis as a useful technique for epidemiological studies.

A total of 60 Mycobacterium tuberculosis strains isolated in the area of Pisa, Italy, over a period from April 1993 to December 1995, were analyzed for the IS6110-based restriction fragments length polymorphism (RFLP). Isolates were found to show a great heterogeneity and only few isolates shared identical DNA banding patterns. In particular, 55 distinct IS6110 patterns were found (average number of isolates per pattern: 1.09) and only 9 strains (15%) occurred in 4 clusters of 2-3 identical clones. Computer analysis of genetic similarities among the strains revealed a family of 17 isolates including the clustered clones implicated in recently acquired infections. No correlation was found between the RFLP DNA patterns of the isolates and drug susceptibility. Of the 5 isolates from immigrants only one showed abnormal DNA fingerprinting. Our data indicate that the patterns of M. tuberculosis isolates in Pisa area are comparable to those of countries with low-prevalence TB and that a low level of TB transmission occurs in this area.

DNA restriction fragment length polymorphism (RFLP) analysis was performed on Mycobacterium tuberculosis isolates from patients in the human immunodeficiency virus (HIV) Unit of a community hospital. It was found that M. tuberculosis isolates from two patients with AIDS shared an identical RFLP pattern. Such a fingerprint was not found in M. tuberculosis isolates from any of 40 HIV-negative patients hospitalized in different Units over the same period, assumed as representative of the strains present in the community, thus ruling out that the isolates from the two AIDS patients might match because only a few strains were present in the community. Clinical records of the two AIDS patients showed an 8-day concomitant hospitalization period in the same ward during which one of the two patients showed active tuberculosis; the second patient developed active tuberculosis less than two months later. These findings strongly support the possibility of nosocomial transmission of tuberculosis.
