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]

In Vitro Resistance to Degradation of Hyaluronic Acid Dermal Fillers by Ovine Testicular Hyaluronidase

DERMATOLOGIC SURGERY, Issue 2010
DEREK JONES MD
BACKGROUND Although adverse events are uncommon with hyaluronic acid (HA) fillers, the use of hyaluronidase permits the reversal of treatment complications or overcorrection. OBJECTIVE This study sought to determine an in vitro dose-response relationship between ovine testicular hyaluronidase (OTH) and three HA dermal fillers (24-mg/mL smooth gel, 20-mg/mL particulate gel, and 5.5-mg/mL particulate gel with 0.3% lidocaine). METHODS AND MATERIALS The dose response of each was measured after incubation for 30 minutes in concentrations ranging between 5 and 40 U of OTH. Timed responses for the 24-mg/mL and 20-mg/mL HA fillers were obtained after incubation with 20 U of OTH for 15 to 120 minutes. RESULTS After all dose responses and timed-interval tests, the 24-mg/mL HA smooth gel filler exhibited more resistance against in vitro enzymatic degradation to OTH than the 20- and 5.5-mg/mL HA particulate gels. CONCLUSION This resistance to degradation in vitro may be attributed to the higher HA content of the 24-mg/mL HA smooth gel, the degree of crosslinking, and the cohesive property of the gel filler.

Fractionated Laser Skin Resurfacing Treatment Complications: A Review

Endoscopic Staple Diverticulostomy for Recurrent Zenker's Diverticulum,

THE LARYNGOSCOPE, Issue 1 2003
Richard L. Scher MD
Abstract Objectives The purpose of this study was to evaluate the technical feasibility, effectiveness, and morbidity of using endoscopic staple diverticulostomy (ESD) as treatment for Zenker's diverticulum (ZD) recurring after either prior endoscopic treatment or external diverticulectomy or diverticulopexy. Study Design A retrospective review of a case series of 18 patients with recurrent ZD. Methods All patients cared for with ZD were evaluated to identify those patients with recurrent ZD. The clinical records of patients with recurrent ZD were reviewed for: demographics, prior treatment, time to recurrence, factors associated with recurrence, technical feasibility of treatment, complications, effectiveness and duration of symptom relief. Results Between March 1995 and July 2001, a total of 127 consecutive patients with ZD received care. Eighteen of these patients were treated for recurrent ZD: nine treated originally by ESD, and nine by external approach (seven by diverticulectomy and two by diverticulopexy), with three of these patients treated twice. Seventeen patients had partial or complete relief of symptoms after their initial treatment, with recurrence of symptoms noted 0 to 60 months later. Specific factors associated with recurrence of symptoms were identified in only one patient. Treatment of recurrent ZD by ESD was technically feasible in 16 of the patients. Complete or improved symptom relief has been reported by 16 of the patients after revision ESD, with follow-up from 9 to 69 months. No significant treatment complications occurred. Fifteen patients resumed clear liquid diet on the day of surgery, and one on the day after surgery. All patients were discharged from the hospital by the second postoperative day (mean = 0.6 d). Conclusions ESD is an effective, technically feasible, and safe treatment for patients with ZD recurring after prior endoscopic or external treatment, and it should be the initial treatment of choice for these patients.

Mortality outcomes in pediatric rheumatology in the US

ARTHRITIS & RHEUMATISM, Issue 2 2010
Philip J. Hashkes
Objective To describe mortality rates, causes of death, and potential mortality risk factors in pediatric rheumatic diseases in the US. Methods We used the Indianapolis Pediatric Rheumatology Disease Registry, which includes 49,023 patients from 62 centers who were newly diagnosed between 1992 and 2001. Identifiers were matched with the Social Security Death Index censored for March 2005. Deaths were confirmed by death certificates, referring physicians, and medical records. Causes of death were derived by chart review or from the death certificate. Standardized mortality ratios (SMRs) and 95% confidence intervals (95% CIs) were determined. Results After excluding patients with malignancy, 110 deaths among 48,885 patients (0.23%) were confirmed. Patients had been followed up for a mean ± SD of 7.9 ± 2.7 years. The SMR of the entire cohort was significantly decreased (0.65 [95% CI 0.53,0.78]), with differences in patients followed up for ,9 years. The SMR was significantly greater for systemic lupus erythematosus (3.06 [95% CI 1.78,4.90]) and dermatomyositis (2.64 [95% CI 0.86,6.17]) but not for systemic juvenile rheumatoid arthritis (1.8 [95% CI 0.66,3.92]). The SMR was significantly decreased in pain syndromes (0.41 [95% CI 0.21,0.72]). Causes of death were related to the rheumatic diagnosis (including complications) in 39 patients (35%), treatment complications in 11 (10%), non-natural causes in 25 (23%), background disease in 23 (21%), and were unknown in 12 patients (11%). Rheumatic diagnoses, age at diagnosis, sex, and early use of systemic steroids and methotrexate were significantly associated with the risk of death. Conclusion Our findings indicate that the overall mortality rate for pediatric rheumatic diseases was not increased. Even for the diseases and conditions associated with increased mortality, mortality rates were significantly lower than those reported in previous studies. [source]

Outcome of Oral Implant Treatment in Partially Edentulous Jaws Followed 20 Years in Clinical Function

CLINICAL IMPLANT DENTISTRY AND RELATED RESEARCH, Issue 4 2006
Odont Dr/PhD, Ulf Lekholm DDS
ABSTRACT Background:, Most long-term follow-up studies of implants in partially edentulous jaws present their outcomes as mean values of implant survival and follow-up time, and few address the fate of the remaining teeth. Purpose:, The aim of this study was to investigate the results of oral implant treatment in partially edentulous jaws after 20 years, and simultaneously to assess what happens to teeth present at the time of implant placement. Materials and Methods:, Seventeen partially edentulous patients, of 27 originally treated individuals, were retrospectively reviewed after receiving implants from 1983 to 1985. The parameters studied were implant survival, prosthesis stability, marginal bone loss at teeth and implants, treatment complications, need for dental treatment, and patient's satisfaction with the outcome. Results:, The cumulative survival rate was 91%, when all 27 patients were assessed, that is, including the 10 dropouts. Of the 69 inserted and followed implants (Brånemark system®; Nobel Biocare AB, Göteborg, Sweden), six failed (8.7%) during the 20-year period, four during the first decade, and the remaining two during the second. A majority (n=4) of the losses were due to implant fractures, two after 8 years, and two after 17 years. In all, 10 of the original fixed bridges being followed (n=24) remained in function during the entire investigation period, whereas 12 were exchanged for new constructions after an average of 7 years. The mean marginal bone loss at teeth was 0.7 mm, and at implants it was 1.0 mm. The major complication observed during the second decade was veneer material fractures, which occurred 14 times in six patients. Component loosening and abutment- and bridge-locking screw fractures were the second most common problems seen, indicating material/component fatigue. Most patients were satisfied with their treatment and many mentioned that they did not think of the constructions as anything but a part of their own body. Conclusion:, Over the decades, treatment of partially edentulous jaws with turned titanium implants seems to function well and to provide patients with good support for fixed short-span bridge constructions.
