Indications, results, and complications of tacrolimus conversion in pediatric renal transplantation

PEDIATRIC TRANSPLANTATION, Issue 6 2001
Joseph T. Flynn
Abstract: It is the practice of many pediatric renal transplant programs to ,convert' children taking cyclosporin A (CsA) to tacrolimus, although the indications for, outcome, and complications of this practice remain obscure. To better understand these aspects of tacrolimus ,conversion', a fax survey was sent to 119 North American pediatric renal transplant centers. Analyzable responses were received from 52 centers (44%), and included data from ,,1,815 pediatric renal transplants performed between 1991 and 98. Strong indications for tacrolimus conversion were: antibody-resistant rejection, CsA-resistant rejection, and CsA intolerance (strong indication in 72%, 65%, and 52% of centers, respectively). Steroid-resistant rejection and cosmetic side-effects were considered strong indications less often. Initial anti-rejection therapy was usually increased corticosteroid dose (47/52 centers). Antibody therapy was most commonly used for steroid-resistant rejection (44 centers). For steroid- and antibody-resistant rejection, tacrolimus conversion was most common (33 centers). Tacrolimus conversion for antibody-resistant rejection led to improvement of serum creatinine (SCr) in 27% of patients, stabilization of SCr in 46%, worsening of SCr in 11%, and graft loss in 16%. Reported complications after tacrolimus conversion included hyperglycemia, hyperkalemia, lymphoproliferative disorder, infection, and neurologic problems. We conclude that the major indication for tacrolimus conversion in pediatric transplant programs appears to be rejection. Outcome after tacrolimus conversion appears good, with the majority of patients experiencing stable or improved allograft function. These data provide direction for further study, including timing of tacrolimus conversion and interaction with other therapies. [source]

Fractionated Laser Skin Resurfacing Treatment Complications: A Review

DERMATOLOGIC SURGERY, Issue 3 2010
ANDREI I. METELITSA MD
BACKGROUND Fractional photothermolysis represents a new modality of laser skin resurfacing that was developed to provide a successful clinical response while minimizing postoperative recovery and limiting treatment complications. OBJECTIVES To review all of the reported complications that develop as a result of fractional ablative and nonablative laser skin resurfacing. METHODS A literature review was based on a MEDLINE search (1998,2009) for English-language articles related to laser treatment complications and fractional skin resurfacing. Articles presenting the highest level of evidence and the most recent reports were preferentially selected. RESULTS Complications with fractional laser skin resurfacing represent a full spectrum of severity and can be longlasting. In general, a greater likelihood of developing post-treatment complications is seen in sensitive cutaneous areas and in patients with intrinsically darker skin phototypes or predisposing medical risk factors. CONCLUSIONS Although the overall rate of complications associated with fractional laser skin resurfacing is much lower than with traditional ablative techniques, recent reports suggest that serious complications can develop. An appreciation of all of the complications associated with fractional laser skin resurfacing is important, especially given that many of them can be potentially prevented. The authors have indicated no significant interest with commercial supporters. [source]

Long-Term Pain Relief in Patients with Cervicogenic Headaches after Pulsed Radiofrequency Application into the Lateral Atlantoaxial (C1-2) Joint Using an Anterolateral Approach

PAIN PRACTICE, Issue 4 2010
FIPP, Willy Halim MD
Abstract The lateral atlantoaxial joint has long been reported as a source of cervicogenic headache. We present a retrospective study, including 86 patients who had undergone lateral C1-2 joint pulsed radiofrequency application, for cervicogenic headache in a single pain center from March 2007 to December 2008. The percentage of patients who had ,50% pain relief at 2 months, 6 months, and 1 year were 50% (43/86), 50% (43/86), and 44.2% (38/86), respectively. Long-term pain relief at 6 months and 1 year were predicted reliably by ,50% pain relief at 2 months (P < 0.001). Apart from 1 patient that complained of increased severity of occipital headache lasting several hours, we had no other reported complications. [source]

Perioperative management of a child with short-chain acyl-CoA dehydrogenase deficiency

PEDIATRIC ANESTHESIA, Issue 9 2005
BRIAN TURPIN BS
Summary Short-chain acyl-CoA dehydrogenase (SCAD) is a mitochondrial enzyme that catalyzes the dehydrogenation of short chain fatty acids (4 to 6 carbons in length) thereby initiating the cycle of , -oxidation. This process generates acetyl-CoA, the key substrate for hepatic ketogenesis or ATP production by the Kreb's cycle. A deficiency of SCAD results in the build-up of potentially cytotoxic metabolites including ethylmalonic acid, methylsuccinyl CoA and butyryl-carnitine. The end-organ involvement is heterogeneous, but most commonly includes hypotonia with possible lipid myopathy and developmental delay. Other reported complications include dysmorphic craniofacial features, hypoglycemia, seizures, scoliosis, hypertonia and hyperreflexia, cyclic vomiting and myocardial dysfunction. We present a 23-month-old girl with SCAD deficiency, who required posterior fossa decompression for type 1 Chiari malformation. The potential perioperative implications of SCAD deficiency are reviewed. [source]
