Epidemiology, aetiology and treatment of skin and soft tissue infections: final report of a prospective multicentre national registry.

Skin and soft tissue infections (SSTIs) represent a heterogenous group of pathological conditions involving the skin or the underlying subcutaneous tissues, fascia and muscle, characterised by a considerable variety of clinical presentations, severity and possible aetiological pathogens. Although previous analyses on restricted types of SSTIs and population have already been published, we conducted a large nationwide surveillance program on behalf of the Italian Society of Infectious and Tropical Diseases to assess the clinical and microbiological characteristics of the whole SSTI spectrum, from mild to severe life-threatening infections, in both inpatients and outpatients and their management. Twenty-nine Infectious Diseases (ID) Centres throughout Italy collected prospectively data concerning both the clinical and microbiological diagnosis of patients affected by SSTIs via an electronic case report form. We included in our database all cases managed by ID specialists participating to the study, independently from their severity or the setting of consultation. Here, we integrated previous preliminary results analysing and reporting data referring to a 3-year period (October 2016-October 2019). During this period, the study population included 478 adult patients with diagnosis of SSTI. The type of infection diagnosed, the aetiological agent involved and some notes on antimicrobial susceptibilities were collected and reported herein. We also analysed the most common co-morbidities, the type and duration of therapy executed, before and after ID intervention and the length of stay. The results of our study provide information to better understand the national epidemiologic data and the current clinical management of SSTIs in Italy.

Epidemiology and Microbiology of Skin and Soft Tissue Infections: Preliminary Results of a National Registry.

Skin and soft tissue infections (SSTIs) represent a wide range of clinical conditions characterized by a considerable variety of clinical presentations and severity. Their aetiology can also vary, with numerous possible causative pathogens. While other authors previously published analyses on several types of SSTI and on restricted types of patients, we conducted a large nationwide surveillance programme on behalf of the Italian Society of Infectious and Tropical Diseases to assess the clinical and microbiological characteristics of the whole SSTI spectrum, from mild to severe life-threatening infections, in both inpatients and outpatients. Twenty-five Infectious Diseases (ID) Centres throughout Italy collected prospectively data concerning both the clinical and microbiological diagnosis of patients affected by SSTIs via an electronic case report form. All the cases included in our database, independently from their severity, have been managed by ID specialists joining the study while SSTIs from other wards/clinics have been excluded from this analysis. Here, we report the preliminary results of our study, referring to a 12-month period (October 2016-September 2017). During this period, the study population included 254 adult patients and a total of 291 SSTI diagnoses were posed, with 36 patients presenting more than one SSTIs. The type of infection diagnosed, the aetiological micro-organisms involved and some notes on their antimicrobial susceptibilities were collected and are reported herein. The enrichment of our registry is ongoing, but these preliminary results suggest that further analysis could soon provide useful information to better understand the national epidemiologic data and the current clinical management of SSTIs in Italy.

Epidemiology and clinical features of cystic hydatidosis in Western Sicily: a ten-year review.

AIM: To assess retrospectively the epidemiological and clinical aspects of cystic echinococcosis (CE) and to evaluate follow-up and response to treatment in patients affected by CE. METHODS: From January 2000 to December 2010, all patients affected by CE at the Infectious Diseases Units of the University of Catania and of Basilotta Hospital in Nicosia-Enna, were enrolled as participants in the study. Epidemiological, clinical and laboratory data were collected for each patient. Diagnosis of CE was performed using clinical imaging and laboratory parameters. Response to treatment was categorized as follows: "cure" as the disappearance or complete calcification of cyst/s; "improvement" as a reduction in the diameter and/or number of existing cysts; and "impairment" as an increase in the diameter and/or number of existing cyst/s and the onset of relapses (i.e., the onset of new cyst/s and an increase in the diameter of previously existing cyst/s and/or complications. Immunoglobulin E (IgE) titers and eosinophil percentages were evaluated at diagnosis, at six months after the initiation of treatment and again in the case of relapse. Hyper-eosinophilia was defined as an eosinophil percentage of ≥ 6%. RESULTS: Thirty-two patients were diagnosed with CE in our Unit during the research period, with a male-female ratio of 2:1. At the time of diagnosis, 40% of patients presented a single CE cyst. Sixty percent showed multi-organ involvement. The liver-lung localization ratio was 2:1. Patients below the age of 50 at diagnosis were more likely to have multiple cysts (73.7% vs 35.5%, P < 0.05). Regarding treatment, 30 patients were treated medically and 16 surgically. Fourteen patients were treated both medically and surgically. Relapses were seen to be less frequent in patients treated with albendazole before and after surgery. Complete cure or an improvement was achieved in 23 patients. Impairment was observed in one patient. Two patients showed no improvement. Relapses were more frequent in those patients treated before 2005. At diagnosis, 71% of patients were positive for specific CE IgE, and 56.3% showed an eosinophil percentage of ≥ 6%. Patients who were diagnosed with hyper-eosinophilia developed complications more frequently than the other patients, but did not suffer relapses. CONCLUSION: On the basis of our results, we propose cystic echinococcosis screening for family members of patients, appropriate pre- and post-surgery treatment and the assessment of anti-echinococcus IgE titer or eosinophil percentage as a therapy response marker in settings with limited resources.

Current practice of hepatitis C treatment in Southern Italy.

BACKGROUND: Only a small proportion of subjects referring to hospitals for hepatitis C virus (HCV) positivity receives antiviral therapy. AIM: To evaluate the rate of antiviral treatment and the causes for no treatment in HCV-RNA positive subjects seen in hospital settings. PATIENTS AND METHODS: A prospective study enrolling over a 6-month period (February-July 2009) all consecutive anti-HCV positive subjects initially referred (naïve patients) to 12 liver units in Southern Italy for HCV treatment. RESULTS: Out of 608 subjects evaluated, 74 (12.2%) had no detectable HCV-RNA in the serum and thus were excluded. Of the remaining 534 HCV-RNA positive subjects, 357 (66.9%) were not treated for the following reasons: 49.9% were older than 65 years of age (75% of them >70 years), 14.3% had normal liver enzymes, 13.2% had compensated/decompensated cirrhosis, 10.4% refused treatment, 9.8% had ongoing substance or alcohol abuse. Multivariate analysis showed that females (O.R. 2.27; C.I. 95% 1.05-4.90) and subjects with low educational level (O.R. 4.38; C.I. 95% 1.27-15.11) were more likely to decline therapy. CONCLUSIONS: The majority of patients with HCV infection does not receive antiviral treatment. The effectiveness of the current standard therapy for HCV infection is low despite its good efficacy.

[Pott's disease in a patient affected with epilepsy and behavioural abnormalities]. / Morbo di Pott in soggetto con epilessia, turbe comportamentali e disturbi cognitivi: descrizione di un caso clinico.

The authors report on a case of Pott's disease in a patient attending a long-term psychiatric hospital for about 34 years. Difficulties regarding case management concern either diagnosis, due to the numerous and misleading comorbidities, or pharmacological treatment, due to both the interference between neurotropic and antitubercular drugs and the capacity of some antimycobacterial drugs to reduce significantly the epileptogenic threshold, thus enhancing epileptic crises.

[The importance of monitoring legionellosis in hospital setting: the case of a Sicilian Hospital]. / Considerazioni circa l'utilità del monitoraggio della presenza di legionelle in ambiente ospedaliero: una esperienza presso un ospedale siciliano.

Hospital-acquired legionellosis is a major problem. In Italy this issue is still underestimated because the reported figures are lower than the actual cases. This is probably due to a lack of diagnosis and monitoring. In Sicily, no cases of hospital-acquired legionellosis were reported in the last few years. In the year 2001, a reference laboratory was set up to help health authorities monitor and prevent hospital-acquired legionellosis. The authors report the data concerning a measure of environmental monitoring and water treatment carried out in a hospital where no legionellosis was ever detected before.
