An acute febrile outbreak in a refugee community of an Italian asylum seeker center: lessons learned

OBJECTIVES

The management of infectious outbreaks in closed settings represents an important public health issue. An outbreak of acute febrile syndrome affecting 22 refugees resident at the Asylum Seekers Centre of Castelnuovo di Porto in Rome has been reported, and the preventive and control measures adopted have been described as an example of public health safety.

METHODS

Pharyngeal swab and whole-blood samples were collected from 22 cases observed and analyzed for standard bacterial cultures and respiratory and herpesviruses by qualitative CLART PneumoVir2 and Entherpex microarray.

RESULTS

A possible respiratory-transmitted etiology and a concomitant reactivation of multiple herpesviruses have been evidenced. The epidemiological investigation showed that the spread of the epidemic was promoted because patients were hosted in neighboring rooms or in the same room, facilitating the rapid spread of infectious disease.

CONCLUSIONS

The potential way of transmission was supposed, and preventive measures for infection control were adopted. The measures adopted are an example of best practice for outbreak management, and the microbiological surveillance is recommended for public health improvement.

Efficacy of Collagen Shields after Extracapsular Cataract Extraction

The efficacy of presoaked porcine collagen shields was compared with subconjunctivally injected corticosteroids and antibiotics in reducing ocular inflammation after ECCE with IOL implantation, and signs of reduced oxygen delivery to the cornea were assessed. Fifty eyes of fifty patients were recruited. At the end of surgery 25 eyes (group 1) received a 24-h shield presoaked with 0.1% betamethasone disodium phosphate and 0.5% netilmycin. The other 25 eyes (group 2) received 1 mg betamethasone disodium phosphate and 250 mg piperacillin as a subconjunctival injection. The eyes were then taped closed. Inflammatory parameters (anterior chamber flare, fibrin, folds of Descemet's membrane, corneal edema) and tolerability of the delivery system (pain, itching) were evaluated 24 h after surgery. None of the patients lost the shield and the collagen devices were well tolerated. Groups 1 and 2 showed no significant differences in the parameters considered. There was, however, transient, slight diffuse superficial corneal edema in 24% of group 1 and 4% of group 2, raising the question of inadequate oxygen transmission through collagen shields under closed lids. The results suggest that collagen shields used with the right solution have no significant adverse effect and may be a less invasive alternative to subconjunctival injection.

[Biosafety in laboratories concerning exposure to biological agents]

Laboratory workers are exposed to a variety of potential occupational health hazards including those deriving from infectious materials and cultures, radiations, toxic and flammable chemicals, as well as mechanical and electrical hazard. Although all of them are significant, this paper will focus on biological hazards present in clinical and research laboratories. In fact, in spite of numerous publications, guidelines and regulations, laboratory workers are still subject to infections acquired in the course of their researches. This paper describes some aspects that include good microbiological practices (GMPs), appropriate containment equipment, practices and operational procedures to minimize workers' risk of injury or illness.

Bile duct injuries during laparoscopic cholecystectomy: a 1994-2001 audit on 13,718 operations in the area of Rome

BACKGROUND

Bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC) still are reported with greater frequency than during open cholecystectomy (OC).

METHODS

In 1999, a retrospective study evaluating the incidence of BDIs during LC in the area of Rome from 1994 to 1998 (group A) was performed. In addition, a prospective audit was started, ending in December 2001 (group B).

RESULTS

In group A, 6,419 LCs were performed (222 were converted to OC; 3.4%). In group B, 7,299 LCs were performed (225 were converted to OC; 3.1%). Seventeen BDIs (0.26%) occurred in group A and 16 (0.22%) in group B. Overall, mortality and major morbidity rates were 12.1% and 30.3%, respectively, without significant differences between the two groups.

CONCLUSIONS

The incidence and clinical relevance of BDIs during LC in the area of Rome appeared to be stable over the past 8 years and were not influenced by the use of a prospective audit, as compared with a retrospective survey.

[Biodegradable anastomotic rings in colonic emergency surgery]

In this work, the authors describe their own experience concerning emergency surgery on large bowel. Frequently, in emergency surgery, the primary disease is associated with a picture of heavy peritonitis that in most cases needs very difficult and immediate operation including intestinal derivation (temporary colostomy). The possibility of restoring the intestinal continuity during the first surgical operation, is the primary aim of the surgeon. Therefore, availability of tools such as BAR (Biodegradable Anastomotic Rings) in performing intestinal anastomosis characterized by strong reliability if compared to stapler suturations avoids temporary colostomy otherwise necessary. This work refers to retrospective study in a group of patients who underwent colic resection with immediate restoration of the intestinal continuity without a protection colostomy. Actually, using biodegradable anastomotic rings like BAR when performing the anastomosis, has some technical advantages, such as low incidence of intra and postoperative complications, short hospitalization period and better management of the patient.
