Benefits of a 14-year surgical site infections active surveillance programme in a French teaching hospital.

BACKGROUND: Surgical site infections (SSIs) are the second most common healthcare-associated infection. Active SSI surveillance can help inform preventative measures and assess the impact of these measures. AIM: We aimed to describe the evolution in trends over 14 years of prospective active SSI surveillance and implementations of SSI prevention measures in a French Teaching Hospital. METHODS: We monitored and included in the study all surgical procedures performed from 2003 to 2016 in eight surgical units. The semi-automated surveillance method consisted of weekly collection of SSI declaration forms (pre-filled with patient and procedure administrative data and microbiology laboratory data), filled-in by surgeons and then monitored by the infection control practitioners. FINDINGS: A total of 181,746 procedures were included in our analysis and 3270 SSIs recorded (global SSI rate 1.8%). The SSI rate decreased significantly from 3.0% in 2003 to 1.1% in 2016. This decrease was mainly in superficial SSIs and high infectious risk procedures. Higher SSI rates were observed for procedures associated with the usual risk factors. During this 14-year period, several evolutions in surgical practices occurred that might have contributed to this decrease. CONCLUSIONS: With an overall decrease in SSI rate throughout the surveillance, our results revealed the benefits of an active and comprehensive hospital SSI surveillance programme for understanding the SSI rate trends, analysing local risk factors and assessing the effectiveness of prevention strategies. These findings also highlighted the importance of the collaboration between surgeons and infection control practitioners.

Use of Permacol™ to restore depression after temporal muscle flap: A case report.

The temporal muscle has been an essential tool in maxillo-facial reconstruction for more than a century. Despite many technical advances, depression in the temporal fossa after its use is a constant issue. There are several ways to fill this defect. However, their efficiency has not been proven. Currently, biomaterials (e.g. polymethylmethacrylate [PMMA] and polyethylene [PE]) are the alternative most frequently used and studied. This is the first case report of temporal depression filling with a porcine dermal matrix (Permacol™). A 58-year-old woman underwent limited maxillectomy for squamous cell carcinoma of the upper vestibular mucosa, after which a pure temporalis muscle flap was used for immediate reconstruction. A custom-shaped Permacol™ sheet was used with a PMMA spacer to fill the resulting depression at the temporal fossa. The procedure went smoothly without any complications. The surgeon and the patient are satisfied with the cosmetic result. Permacol™ is a safe and effective tool to fill defects after temporalis muscle flap and is an excellent alternative to other biomaterials currently on the market.

Depression after temporal muscle flap: A systematic review of the literature.

BACKGROUND: There are several ways to fill the depression created after temporal muscle flap. Historically, many methods have been described but biomaterials are increasingly used for this indication. We conducted a systematic review of the literature on the use of biomaterials to fill this depression. METHODS: The databases MEDLINE (via PubMed), Cochrane Library, EBSCO, Web of Sciences and Embase were searched for clinical trial reports, case series, case reports and cohort studies from 1991 to 2015. We conducted a systematic review of the use and efficacy of different biomaterials. Patient satisfaction was systematically researched. RESULTS: We identified 11 articles (196 patients) which were included in the systematic review. The biomaterials used are polymethyl methacrylate (PMMA), polyethylene (PE), lipofilling, Titanium (Ti) and Mersilene Mesh (MM). Complications occurred only with PMMA and MM. Patient satisfaction was rather good in all the studies. CONCLUSION: There is no evidence of the superiority of one biomaterial over another as there was a lack of high quality studies. More randomized and controlled studies are required to draw conclusions on the matter.

Cell-assisted lipotransfer: Friend or foe in fat grafting? Systematic review and meta-analysis.

Autologous fat grafting is a common procedure for soft-tissue reconstruction but is associated with a graft resorption rate ranging from 20% to 80%. To improve the fat graft survival rate, a new technique, called cell-assisted lipotransfer (CAL), was developed. With CAL, fat is injected along with adipose-derived stromal cells that are assumed to improve fat survival rate. We conducted an evidence-based meta-analysis to evaluate the efficacy and safety of CAL as compared with conventional autologous fat grafting (non-CAL). The databases MEDLINE (via PubMed), Cochrane Library, EBSCO, Web of Science, and EMBASE were searched for reports of clinical trials, case series, and cohorts available from 2008 to 2016. We conducted a meta-analysis of the efficacy of CAL with data analysis concerning fat survival rate. The incidence of complications and the need for multiple procedures were evaluated to determine the safety of CAL. We identified 25 studies (696 patients) that were included in the systematic review; 16 studies were included in the meta-analysis to evaluate the efficacy of CAL. The fat survival rate was significantly higher with CAL than non-CAL (64% vs. 44%, p < .0001) independent of injection site (breast and face). This benefit of CAL was significant for only injection volumes <100 ml (p = .03). The two groups did not differ in frequency of multiple procedures after fat grafting, but the incidence of complications was greater with CAL than non-CAL (8.4% vs. 1.5%, p = .0019). The CAL method is associated with better fat survival rate than with conventional fat grafting but only for small volumes of fat grafting (<100 ml). Nonetheless, the new technique is associated with more complications and did not reduce the number of surgical procedures needed after the first fat grafting. More prospective studies are required to draw clinical conclusions and to demonstrate the real benefit of CAL as compared with common autologous fat grafting.

[Transcient ischemic attack, a rare manifestation of Eagle syndrome]. / Accident ischémique transitoire, une manifestation rare du syndrome d'Eagle.

INTRODUCTION: Clinical presentation of Eagle syndrome (ES) is very variable and non-specific, making its diagnosis difficult. It is usually limited to pain. Transient neurological manifestations are exceptional. We report one case in which the diagnosis of ES has been made based on neurological events occurring during left anterolateral head bending, without pain. OBSERVATION: A 47-year-old man presented with transient neurological events progressing since two years, half-right body paresthesia and reduced field of vision on the left side type, triggered by left anterolateral head flexion and regressive in neutral position. Transcranial Doppler and CT angiography of the supra-aortic trunks were performed in neutral position and in right and left head rotation that showed a disruption of the left sylvian flow and an extrinsic compression of the left internal carotid artery, due to a musculoskeletal impediment involving the lower end of the temporal styloid process. Complete recovering was achieved after surgical resection of this process. A control CT angiography confirmed the cessation of the compression. DISCUSSION: ES has non-specific and highly variable clinical manifestations making diagnosis difficult or leading to misdiagnosis. ES should be considered in any transient neurological deficit, especially when occurring during head rotation. Treatment relies on surgical resection of the excessively long styloid process.

[Radiation-induced sarcoma of the head and neck]. / Sarcomes radio-induits de la tête et du cou.

INTRODUCTION: Radiation-induced sarcoma (RIS) of the head and neck is a late and rare complication of cancer treatment by radiation therapy. It occurs mostly within the limits of the irradiated area. Its incidence is increasing and related to an improved survival rate of treated patients. But it does not rule out the use of radiotherapy in the treatment of this cancer. OBSERVATION: We report two cases of sarcoma having appeared in the irradiated area, in patients treated by adjuvant radiotherapy for head and neck neoplasm. DISCUSSION: The prognosis for this sarcoma depends mainly on how early the diagnosis is made and the quality of surgical resection. Adjuvant chemotherapy or radiotherapy can be considered. Ongoing research on the expression of RIS genes could soon lead to new treatments.

[Histological classification of sarcomas]. / Classification histologique des sarcomes.

Sarcomas are rare and malignant tumors of mesenchymatous origin. Numerous histological sub-types have been described. 10 to 15% of all sarcomas are located to head and neck. The more frequent histological types in this localization are fibrosarcoma, malignant fibrous histiocytoma and rhabdomyosarcoma. In this paper a general review of histological classification of sarcomas is proposed with a particular emphasis on head and neck sarcomas.

[Cervicofacial involvement of primary cutaneous neuroendocrine carcinomas or Merkel cell tumors: therapeutic considerations]. / Localisations cervico-faciales des carcinomes neuroendocrines cutanés primaires ou tumeurs à cellules de Merkel: considérations thérapeutiques.

Seven cases of primary skin neuroendocrine carcinoma or Merkel cell tumours with cervico-facial localization are reported. The poor prognosis of these tumours is essentially due to the potential for local recurrence and the frequency of locoregional and visceral metastasis. Surgical treatment is required but rarely sufficient to control the disease. Complementary radiotherapy, when performed early, can reduce the rate of locoregional recurrence. Lymph node resection is important to determine prognosis but has not been proven to improve outcome. In addition, parotid metastasis appears to result from blood stream dissemination and has a very poor prognosis. Exclusive radiotherapy may be discussed in such cases.

Epidemiology of interstitial lung disease (ILD) in flanders: registration by pneumologists in 1992-1994. Working group on ILD, VRGT. Vereniging voor Respiratoire Gezondheidszorg en Tuberculosebestrijding.

Worldwide almost no epidemiologic data are available on the prevalence or incidence of interstitial lung diseases (ILD) in the general population. Therefore, a registration programme of ILD-prevalence was organised by the VRGT (Vereniging voor Respiratoire Gezondheidszorg en Tuberculosebestrijding), among about 100 Flemish pneumologists since 1990. Most categories of the classification by Crystal et al. (1) were included and the diagnostic criteria (histology, laboratory tests, clinic, radiology) were registered. The present paper presents the results of 1992-1994: twenty pneumologists had forwarded the summary files of 237 patients to the central office in 1992 (n = 68), 1993 (n = 90) and 1994 (n = 79). The diagnoses that were most frequently made were: sarcoidosis in 27%, idiopathic pulmonary fibrosis in 20%, hypersensitivity pneumonitis in 14% (of which 68% by birds) and collagen-vascular disease in 10% (of which 54% in rheumatoid arthritis). Less frequent causes were eosinophilic pneumonia (4%), inhalation of inorganic material (4%, anthracosilicosis being excluded), histiocytosis X (3%), drugs (3%), angiitis and granulomatosis (2%), pulmonary hemosiderosis (1%), lymphocytic infiltrative lung disease (1%) and lymphangioleiomyomatosis (1%). The order of relative frequencies of the different categories of diseases was the same in the 3 registration years. In 9% of the patients the diagnosis was confined to "undefined fibrosis". The diagnosis was confirmed by histology in 63% of the cases. The overall male-female ratio was nearly one, with, however, a male preponderance in hypersensitivity pneumonitis (22/12), UIP(8/3) and "undefined fibrosis" (14/7).(ABSTRACT TRUNCATED AT 250 WORDS)
