Caspofungin in the treatment of azole-refractory esophageal candidiasis in kidney transplant recipients.

BACKGROUND: Infection is a common cause of morbidity and mortality in kidney transplant recipients. The incidence of esophageal and urogenital candidiasis in kidney and kidney-pancreas transplant recipients has not been well documented. Azoles are safe, effective agents to treat esophageal candidiasis. However, resistance to azoles is now becoming common. This study reports the use of caspofungin for the treatment of azole-resistant esophageal and urogenital candidiasis in kidney transplant recipients. PATIENTS AND METHODS: The incidence of esophageal and urogenital candidiasis was evaluated among 140 kidney transplantations and four combined kidney-pancreas transplants performed over a 2-year period. RESULTS: Twenty-two patients (15.7%) presented with esophageal candidiasis, while seven patients (5%) showed urogenital candidiasis. Thirteen patients with esophageal candidiasis (59%) and four patients (57%) with urogenital candidiasis did not improve after a week of azole treatment. A regimen of caspofungin was started in these patients, who tolerated the treatment. Urogenital candidiasis recurred in two patients 2 and 3 months after the treatment. One patient with esophageal candidiasis did not improve with caspofungin and was switched to amphotericin B therapy. There were no other recurrences of candidiasis among patients treated with caspofungin for a median follow-up of 8 months. CONCLUSIONS: Renal transplant patients remain at high risk for fungal infections. Although the number of patients was limited, the results of this study indicated that caspofungin is an effective, well-tolerated alternative for difficult-to-treat, azole-resistant candida infections in kidney and pancreas transplant recipients. The high costs of the drug limit the use of caspofungin as first-line antifungal therapy, reserving its use to recipients who had undergone unsuccessful azole therapy.

Continuous intrathecal baclofen administration by a fully implantable electronic pump for severe spasticity treatment: our experience.

AIM: With this 8-month study, we wanted to evaluate the efficacy of continuous intrathecal baclofen infusion delivery by a programmable pump for severe spasticity according to patient selection criteria, implantation technique and related parameters, and outcome after the initial follow-up period. METHODS: Intrathecal baclofen infusion was initiated in 30 patients within 24 h after a test dose of the agent resulted positive in spinal anaesthesia. During the procedure and the follow-up period, the following parameters were measured: incidence of anaesthesiological or surgical complications and adverse events, postdural puncture headache, prolonged motor block, difficulty in wound healing, infection, necessity to remove the pump; clinical response as measured on the Ashworth and spasms scales, quality of sleep, autonomy, quality of life and pain before and after intrathecal baclofen therapy. RESULTS: Perioperative vital parameters (mean duration of the operation, 86+/-13 min) were stable; no motor block or postdural puncture headache, early or late infection developed. The 1 case of delayed wound healing resolved with treatment; a dislocated catheter was repositioned in 1 other case. The differences in changes between pre- and posttreatment were statistically significant, with best results obtained on rigidity and pain. The mean length of hospital stay was 8+/-2 days. Baclofen tolerance was observed in 1 case, but resolved after baclofen holiday with morphine. One case of pump malfunctioning was resolved with replacement of the device; no new neurological deficits occurred thereafter. CONCLUSIONS: The good clinical response to treatment of spasticity and rigidity, improved quality of life, pain reduction and patient satisfaction with short length of admission demonstrate the efficacy of intrathecal baclofen therapy. Safe and efficacious, this mode of treatment appears to be the gold standard for treating severe spasticity.

Experimental research and surgery: why, how, and when?

Experimental research faces two great problems: the significant reduction of public funding and the firm opposition of the public opinion. The law forbids the use of large animals, so that it is possible to use small animals only, which require microsurgical techniques. However, even a skillful surgeon does not know how to perform microsurgery and has to begin a long and tiring training to master techniques. We think that experimental surgery should play a role because it tests the validity and safety of new surgical techniques and allows special pathophysiological aspects to be studied. Furthermore experimental surgery could represent an essential stage in the training of young surgeons. We should find a balance between observance of the law and respect of the animals and, on the other hand, the role of experimental surgery because we should not forget that its most important aim is the improvement of the health of the humankind.

Experimental anaesthesiologic protocol for porto-intracaval shunt for liver total vascular exclusion: preliminary study in the rabbit.

The aim of this study was to evaluate the effects and interference of different anaesthetic techniques in rabbits undergoing liver total vascular exclusion using a porto-intracaval shunt. Twenty New Zealand rabbits were divided in three groups: group A receiving diazepam as premedication, ketamine + atropine for induction and maintenance of anaesthesia and undergoing a porto-intracaval shunt operation; group B receiving midazolam as premedication, ketamine + fentanyl + atropine for induction and maintenance of anaesthesia and undergoing a porto-intracaval shunt operation; group C receiving the same drugs as group B but undergoing a simple portal and caval clamping. The following parameters were studied: efficacy of premedication, vital parameters before and after clamping and insertion of the shunt, mean time to clamp and insert the shunt, mean survival time after clamping (group C) or activation of the shunt (groups A and B). Midazolam was significantly better for premedication; there was no statistically significant difference between groups A and B for the vital parameters, for the time necessary to clamp and insert the shunt, for the intraoperative course, and for the mean survival time. The absence of a statistically significant difference between groups could be due to the low number of animals used in the study. There is actually evidence that a correct anaesthesiologic protocol, especially referring to analgesia and fluid management, improves the outcome of operated animals. Surely further studies, possibly conducted on a larger number of animals, are required to evaluate better the results observed and to consider applying these data and this experience to humans.

Attachment processes in eating disorders.

Anxious and insecure attachment, fear of abandonment and difficulties with autonomy differentiate young women with eating disorders from their normal peers. This paper uses the Adult Attachment Interview (AAI) as the correlation between eating disorders and state of mind regarding attachment (7 females and 6 males) with anorexia nervosa and EDNOS. There was a higher frequency of dismissing or entangled states of mind. The sample is far too small to allow statistical inferences to be drawn about differences between men and women in the style of state of mind regarding attachment. An inference is none the less made with regard to the role of psychotherapy in these results.
