Successful Treatment of Spondylodiscitis and Infectious Sacroiliitis due to Listeria monocytogenes using Meropenem as Salvage Therapy.

Infectious sacroiliitis is a rare disease that can occur in conjunction with other osteoarticular infections. Furthermore, it is very unusual for Listeria monocytogenes to be identified in an osteoarticular infection, with spondylodiscitis being the most frequent such infection. We report a case of spondylodiscitis with infectious sacroiliitis due to infection with L. monocytogenes treated successfully with meropenem as salvage therapy. LEARNING POINTS: It is very unusual for Listeria monocytogenes to be identified in an osteoarticular infection.L. monocytogenes can cause infectious sacroiliitis, which is a rare disease.Meropenem has been proposed as salvage therapy and was successful in our case.

Drugs prescribed for patients hospitalized in a geriatric oncology unit: Potentially inappropriate medications and impact of a clinical pharmacist.

OBJECTIVES: The aim of this study was to assess the prevalence of potentially inappropriate medication (PIM) use upon admission and at discharge in a geriatric oncology unit after involving a clinical pharmacist. Although the few studies conducted in geriatric oncology units used the 2003 Beers criteria, this study used START and STOPP criteria, a more appropriate tool for European formularies. MATERIALS AND METHODS: Prospective study in older (≥70years) patients consecutively admitted to a geriatric oncology unit in a cancer center from July 2011 to April 2012. Clinical pharmacist conducted a complete comprehensive medication review including non-prescription and complementary (herbals) medications. This information coupled with the patient's medical history allows identifying PIMs using the STOPP and START criteria. The number of PIMs at admission and at discharge from the hospital was compared after clinical pharmacist intervention. RESULTS: Ninety-one older patients with cancer (mean age±SD=79±6years) were included in the study. START criteria identified 41 PIMs for 31 persons (34%) at admission compared to 7 PIMs for 6 persons (7%) at discharge. STOPP criteria identified 50 PIMs at admission for 29 persons (32%) compared to 16 PIMs at discharge for 14 persons (16%). Results showed significantly lower START scores at discharge than at admission (p<0.001); similarly, STOPP criteria demonstrated fewer PIMs at discharge than at admission (p<0.001). CONCLUSION: The use of START and STOPP criteria by a clinical pharmacist allows identifying PIMs and changing prescriptions for older patients with cancer in agreement with the oncologist and geriatrician of the team.

Chronic maxillary rhinosinusitis of dental origin: a systematic review of 674 patient cases.

Objectives. The aim of this systematic review is to study the causes of odontogenic chronic maxillary rhinosinusitis (CMRS), the average age of the patients, the distribution by sex, and the teeth involved. Materials and Methods. We performed an EMBASE-, Cochrane-, and PubMed-based review of all of the described cases of odontogenic CMRS from January 1980 to January 2013. Issues of clinical relevance, such as the primary aetiology and the teeth involved, were evaluated for each case. Results. From the 190 identified publications, 23 were selected for a total of 674 patients following inclusion criteria. According to these data, the main cause of odontogenic CMRS is iatrogenic, accounting for 65.7% of the cases. Apical periodontal pathologies (apical granulomas, odontogenic cysts, and apical periodontitis) follow them and account for 25.1% of the cases. The most commonly involved teeth are the first and second molars. Conclusion. Odontogenic CMRS is a common disease that must be suspected whenever a patient undergoing dental treatment presents unilateral maxillary chronic rhinosinusitis.

The helicase-like transcription factor is a strong predictor of recurrence in hypopharyngeal but not in laryngeal squamous cell carcinomas.

AIMS: To examine the immunohistochemical expression of helicase-like transcription factor (HLTF) in relation to the prognosis of hypopharyngeal (HSCCs) and laryngeal (LSCCs) squamous cell carcinomas, and to characterize the HLTF protein variants expressed in biopsy specimens of head and neck squamous cell carcinoma (HNSCC) as well as the HeLa cell line. METHODS AND RESULTS: HLTF expression was determined by immunohistochemistry on a series of 100 hypopharyngeal (stage IV) and 56 laryngeal SCCs (stages I, II and IV). The HLTF variants were defined using reverse transcriptase-polymerase chain reaction and Western blots in 13 fresh HNSCC biopsies and in HeLa cells. High levels of HLTF expression were associated with rapid recurrence rates in a subgroup of 81 stage IV hypopharyngeal SCCs (with complete follow-up). A 95-kDa HLTF variant truncated at the carboxyl-terminal domain was detected in addition to the 115-kDa full-size protein in HNSCC biopsies, while six variants were observed in HeLa cells. CONCLUSIONS: Our results demonstrate, for the first time, that hypopharyngeal SCCs presenting high levels of HLTF have a worse prognosis. The quantitative determination of HLTF in hypopharyngeal SCCs was an independent prognostic marker alongside tumour node metastasis staging. HNSCCs expressed the truncated HLTF variant lacking the domains involved in DNA repair.

Helicase-like transcription factor exhibits increased expression and altered intracellular distribution during tumor progression in hypopharyngeal and laryngeal squamous cell carcinomas.

The helicase-like transcription factor (HLTF) belongs to the SWI/SNF family of proteins that use the energy from adenosine triphosphate hydrolysis to remodel chromatin during a variety of cellular processes. HLTF is also involved in DNA repair. Using computer-assisted microscopy, the immunohistochemical expression of HLTF was determined using a series of 100 hypopharyngeal and 56 laryngeal squamous cell carcinomas (SCCs) compared to tumor-free epithelia (60 cases) and dysplasias (92 cases). In hypopharyngeal SCC tumor progression, increased HLTF expression was associated with the percentage of immunopositive epithelial tissue areas (p = 0.02) and the staining intensity of the positive area (p = 0.0005). In the cases of laryngeal lesions, the immunolabeling intensity of HLTF significantly decreased with malignancy (p = 0.01). We also observed a significant shift of HLTF expression from the cytoplasm toward the nuclear compartment (p = 0.0007). Our data reveal an association between the presence of HLTF and neoplastic progression of hypopharyngeal and laryngeal SCCs.
