Rhino-cerebral zygomycosis (RCZ) is an acute rapidly progressive fungal infection usually occurring in patients with diabetes mellitus and ketoacidosis. Patients typically complain of pain located in the facial, nasal or orbital regions, followed by sudden blindness and cranial nerve palsy. Early diagnosis, correction of risk factors, prompt surgical removal and aggressive antifungal therapy are warranted as life-saving treatments. The following report describes a case of a lethal RCZ which occurred in an apparently healthy woman with latent non-decompensated diabetes mellitus and a fetal-type posterior (FTP) circle of Willis.

OBJECTIVES: The objective of this study was to investigate the role that psychopathological dimensions as overt aggression and impulsivity play in determining suicide risk in benign chronic pain patients (CPPs). Furthermore we investigated the possible protective/risk factors which promote these negative feelings, analyzing the relationship between CPPs and their caregivers. METHODS: We enrolled a total of 208 patients, divided into CPPs and controls affected by internistic diseases. Assessment included collection of sociodemographic and health care data, pain characteristics, administration of visual analog scale (VAS), Modified Overt Aggression Scale (MOAS), Barratt Impulsiveness Scale Version 11 (BIS), Hamilton Depression Rating Scale (HDRS), and a caregiver self-administered questionnaire. All variables were statistically analyzed. RESULTS: A significant difference of VAS, MOAS-total/verbal/auto-aggression, HDRS-total/suicide mean scores between the groups were found. BIS mean score was higher in CPPs misusing analgesics. In CPPs a correlation between MOAS-total/verbal/auto-aggression with BIS mean score, MOAS with HDRS-suicide mean score and BIS with HDRS-suicide mean scores were found. The MOAS and BIS mean scores were significantly higher when caregivers were not supportive. CONCLUSION: In CPPs, aggression and impulsivity could increase the risk of suicide. Moreover, impulsivity, overt aggression and pain could be interrelated by a common biological core. Our study supports the importance of a multidisciplinary approach in the CPPs management and the necessity to supervise caregivers, which may become risk/protective factors for the development of feelings interfering with the treatment and rehabilitation of CPPs.

Multiple-site colonization with Candida spp. is commonly recognized as a risk factor for invasive fungal infection in critically ill patients. We carried out a study to determine the relationship between Candida colonization and invasive infection in neurological patients admitted to an ICU. At admission (T0) and every three days for two weeks, different samples (pharynx swab, tracheal secretions, stomach contents, etc.) were collected for mycological surveillance. Candida mannan antigen and Candida anti-mannan antibodies were assayed. The Colonization Index (CI) and Corrected Colonization Index were calculated for each time point. Of all patients 70% was already colonized by Candida spp. at T0 and six of them had CI ≥ 0.5. Three patients developed candidemia; they had CI ≥ 0.5 before infection. Positive values of Candida mannan antigen and anti-mannan antibodies were found only in the patients with candidemia. The sensitivity and specificity of the Candida mannan test were 66.6% and 100%, respectively, while the sensitivity and specificity of the anti-mannan antibody test were 100%. In accordance with other authors, we find the surveillance cultures are useful to monitor the Candida colonization in ICU patients. In addition, the sequential observation of anti-mannan antibodies could contribute to early diagnosis of candidiasis more than Candida mannan antigen in immunocompetent patients.

Background. Gram-negative bacteria susceptible only to colistin (COS) are emerging causes of severe nosocomial infections, reviving interest in the use of colistin. However, consensus on the most effective way to administer colistin has not yet been reached. Methods. All patients who had sepsis due to COS gram-negative bacteria or minimally susceptible gram-negative bacteria and received intravenous colistimethate sodium (CMS) were prospectively enrolled. The CMS dosing schedule was based on a loading dose of 9 MU and a 9-MU twice-daily fractioned maintenance dose, titrated on renal function. For each CMS course, clinical cure, bacteriological clearance, daily serum creatinine clearance, and estimated creatinine clearance were recorded. Results. Twenty-eight infectious episodes due to Acinetobacter baumannii (46.4%), Klebsiella pneumoniae (46.4%), and Pseudomonas aeruginosa (7.2%) were analyzed. The main types of infection were bloodstream infection (64.3%) and ventilator-associated pneumonia (35.7%). Clinical cure was observed in 23 cases (82.1%). Acute kidney injury developed during 5 treatment courses (17.8%), did not require renal replacement therapy, and subsided within 10 days from CMS discontinuation. No correlation was found between variation in serum creatinine level (from baseline to peak) and daily and cumulative doses of CMS, and between variation in serum creatinine level (from baseline to peak) and duration of CMS treatment. Conclusions. Our study shows that in severe infections due to COS gram-negative bacteria, the high-dose, extended-interval CMS regimen has a high efficacy, without significant renal toxicity.

Ziconotide is a nonopioid intrathecal analgesic drug used to manage moderate to severe chronic pain. The aim of this work is to assess the safety and efficacy of intrathecal (IT) combination of ziconotide and morphine in malignant pain refractory to high doses of oral opioids. Patients with malignant pain refractory to high oral opioids doses with a mean visual analogue scale of pain intensity (VASPI) score of P70 mm were enrolled. An IT combination therapy was administered: Ziconotide was started at a dose of 2.4 lg/ day, followed by increases of 1.2 lg/day at intervals of at least 7 days, and an initial IT daily dose of morphine was calculated based on its oral daily dose. Percentage change in VASPI scores from baseline was calculated at 2 days, at 7 days, and weekly until the first 28 days. The mean percentage change of VASPI score from baseline was used for efficacy assessment. Safety was monitored based on adverse events and routine laboratory values. Twenty patients were enrolled, with a mean daily VASPI score at rest of 90 ± 7. All had a disseminated cancer with bone metastases involving the spine. The percentage changes in VASPI mean scores from baseline to 2 days, 7 days, and 28 days were 39 ± 13% (95% confidence interval [CI] =13.61–64.49, P < .001), 51 ± 12% (95% CI = 27.56–74.56, P < .001), and 62 ± 13% (95% CI = 36.03– 87.89%, P &

Objective: The Acute Respiratory Distress Syndrome Network protocol recommends limiting tidal volume and plateau pressure; it also recommends increasing respiratory rate to prevent hypercapnia. We tested a strategy that combines the low tidal volume with lower respiratory rates and minimally invasive CO2 removal. Subjects: Ten lung-damaged pigs (instilled hydrochloride). Interventions: Two conditions randomly applied in a crossover fashion: the Acute Respiratory Distress Syndrome Network protocol and the Acute Respiratory Distress Syndrome Network protocol plus lower respiratory rate plus minimally invasive Co2 removal. A similar arterial Co2 partial pressure was targeted in the two conditions. Measurements and Main Results: Physiological parameters, computed tomography scans, plasma and bronchoalveolar lavage concentrations of interleukin-1[beta], interleukin-6, interleukin-8, interleukin-10, interleukin-18, and tumor necrosis factor-[alpha]. During the lower respiratory rate condition, respiratory rate was reduced from 30.5 +/- 3.8 to 14.2 +/- 3.5 (p < 0.01) breaths/min and minute ventilation from 10.4 +/- 1.6 to 4.9 +/- 1.7 L/min (p < 0.01). The extracorporeal device removed 38.9% +/- 6.1% (79.9 +/- 18.4 mL/min) of CO2 production. During the lower respiratory rate condition, interleukin-6, interleukin-8, and tumor necrosis factor-[alpha] concentrations were significantly lower in plasma; interleukin-6 and tumor necrosis factor-[alpha] concentrations were lower in bronchoalveolar lavage, whereas the concentrations of the other cytokines remained unchanged. Conclusion: The strategy of lower respiratory rate plus minimally invasive extracorporeal CO2 removal was feasible and safe and, as compared with the Acute Respiratory Distress Syndrome Network protocol, reduced the concentrations of some, but not all, of the tested cytokines without affecting respiratory mechanics, gas exchange, and hemodynamics.
