Outcomes and risk factors for spontaneous spondylodiscitis: Case series and meta-analysis of the literature.

Despite recent improvements in surgical and antimicrobial therapies, few generally applicable guidelines exist for spondylodiscitis management. We reviewed a consecutive series of patients as well as the past 18 years of the literature and analyzed outcomes for either conservative or surgical treatment. We analyzed a consecutive series of adults with spontaneous spondylodiscitis treated at our institution over the last 6 years. We analyzed predictors for neurological deficits, vertebral collapse, and surgical treatment. We also performed a meta-analysis of the literature between 2000 and 2018, stratifying the results between surgical and conservative treatment outcomes. A younger age at diagnosis, cervical location, tubercular infection, coexistence of morbidities, and vertebral collapse were predictors of surgical intervention. Cervical spondylodiscitis, vertebral collapse, and epidural collection were associated with a higher risk of developing neurological deficits, while tubercular spondylodiscitis was associated with a higher risk of vertebral collapse. Based on the current literature, conservative treatment has success rates similar to those of surgical treatment but lower complication and mortality rates. In cases without an absolute indication for surgery, a conservative approach should be considered as the first-line treatment. A closer diagnostic and clinical follow-up should be recommended in patients with cervical tract or tubercular spondylodiscitis because of the higher risk of developing bone collapse and neurological deficits.

Predictors of choice of initial antifungal treatment in intraabdominal candidiasis.

Intraabdominal candidiasis (IAC) is the second most frequent form of invasive candidiasis, and is associated with high mortality rates. This study aims to identify current practices in initial antifungal treatment (IAT) in a real-world scenario and to define the predictors of the choice of echinocandins or azoles in IAC episodes. Secondary analysis was performed of a multinational retrospective cohort at 13 teaching hospitals in four countries (Italy, Greece, Spain and Brazil), over a 3-year period (2011-2013). IAC was identified in 481 patients, 323 of whom received antifungal therapy (classified as the treatment group). After excluding 13 patients given amphotericin B, the treatment group was further divided into the echinocandin group (209 patients; 64.7%) and the azole group (101 patients; 32.3%). Median APACHE II scores were significantly higher in the echinocandin group (p 0.013), but IAT did not differ significantly with regard to the Candida species involved. Logistic multivariate stepwise regression analysis, adjusted for centre effect, identified septic shock (adjusted OR (aOR) 1.54), APACHE II >15 (aOR 1.16) and presence in surgical ward at diagnosis (aOR 1.16) as the top three independent variables associated with an empirical echinocandin regimen. No differences in 30-day mortality were observed between groups. Echinocandin regimen was the first choice for IAT in patients with IAC. No statistical differences in mortality were observed between regimens, but echinocandins were administered to patients with more severe disease. Some disagreements were identified between current clinical guidelines and prescription of antifungals for IAC at the bedside, so further educational measures are required to optimize therapies.

Clinical and virological findings in the ongoing outbreak of West Nile virus Livenza strain in northern Italy, July to September 2012.

In July-September 2012, one month earlier than in previous years, 13 confirmed human cases of West Nile virus infection were diagnosed in northern Italy, including five with neuroinvasive disease, three with West Nile fever, and five West Nile virus (WNV)-positive blood donors. In nine cases, the presence of the WNV lineage 1a Livenza strain, characterised in 2011, was ascertained. Symptomatic patients had prolonged viruria with high viral load.

Serum thyroglobulin levels in patients with well-differentiated thyroid cancer during suppression therapy: study on 429 patients.

UNLABELLED: Serum thyroglobulin (Tg) was measured in 429 patients with well-differentiated thyroid carcinoma, during thyroid hormone suppression therapy. 324 patients out of 429 were considered free of disease; 44 had only remnants in the thyroid bed; 61 had metastases, of them 40 were detected by TBS and 21 were nonfunctioning and were detected by other diagnostic procedures. Tg was measured by a RIA method in 257 patients and by an IRMA method in 277 patients. The correlation between the two methods was very good (r = 0.914) for values higher than 25 ng/ml with the RIA method. The cut-off limit to distinguish pathological from nonpathological values was considered the mean value found in the patients free of disease plus 2SD. The cut-off limit for the RIA method was 24.2 ng/ml and 3.0 ng/ml for the IRMA method. Of patients with high Tg levels 92% had metastases, either nodal or distant; only 8% had remnants in the thyroid bed. Tg levels were high in 80% of the patients with metastases, all but two of the patients with metastases and low Tg levels had nodal metastases. Moreover, Tg levels were high in 76% of the patients with metastases unable to take up radioiodine. IN CONCLUSION: patients with low levels of serum Tg during suppression therapy have a high probability of being free of disease, even though the presence of tumors cannot be excluded. On the other hand a value greater than the cut-off limit suggests the presence of metastases despite a negative scan.
