RESUMEN

A 60-year-old man presented with a non-healing interdigital ulcer on the right foot. Various treatment regimens had no effect. Three months later, histopathological examination of a biopsy showed an acrolentiginous amelanotic melanoma. Partial foot amputation followed, but metastases were diagnosed several months later. If no improvement occurs in a benign-looking acral lesion, doctors should closely observe the lesion and consider biopsy.

RESUMEN

Photodynamic therapy (PDT) with light emitting diode (LED) illumination is a frequently used treatment modality for actinic keratosis (AK) with excellent cosmetic outcome. A major disadvantage, however, is the high pain score. Pulsed dye laser (PDL) illumination has been suggested, but the long-term efficacy of this treatment is unknown. In this split-face study we prospectively treated 61 patients with AK, with both LED-PDT and PDL-PDT. The mean change in the number of lesions between the end of follow-up and start of therapy was -4.25 (95% confidence interval (95% CI) -5.07; -3.43) for LED-PDT and -3.88 (95% CI -4,76; -2.99) for PDL-PDT, with a non-significant difference (p = 0.258) of -0.46 (95% CI -1.28; 0.35). The percentage decrease from baseline in the total number of AK was 55.8% and 47.8%, respectively, at 12-month follow-up. Visual analogue scale pain score was lower after PDL (mean 2.64) compared with LED illumination (mean 6.47). These findings indicate that PDL-PDT is an effective alternative illumination source fo.

RESUMEN

BACKGROUND: Basal cell carcinoma (BCC) is the most common form of cancer among Caucasians and its incidence continues to rise. Surgical excision (SE) is considered standard treatment, though randomised trials with long-term follow-up are rare. We now report the long-term results of a randomised trial comparing surgical excision with Mohs' micrographic surgery (MMS) for facial BCC. METHODS: 408 facial, high risk (diameter at least 1cm, H-zone location or aggressive histological subtype) primary BCCs (pBCCs) and 204 facial recurrent BCCs (rBCCs) were randomly allocated to treatment with either SE or MMS between 5th October 1999 and 27th February 2002. The primary outcome was recurrence of carcinoma. A modified intention to treat analysis was performed. FINDINGS: For primary BCC, the 10-year cumulative probabilities of recurrence were 4.4% after MMS and 12.2% after SE (Log-rank test χ(2) 2.704, p=0.100). For recurrent BCC, cumulative 10-year recurrence probabilities were 3.9% and 13.5% for MMS and SE, respectively (Log-rank χ(2) 5.166, p=0.023). A substantial proportion of recurrences occurred after more than 5years post-treatment: 56% for pBCC and 14% for rBCC. INTERPRETATION: Fewer recurrences occurred after treatment of high risk facial BCC with MMS compared to treatment with SE. The proportion of recurrences occurring more than 5years post-treatment was especially high for pBCC, stressing the need for long-term follow-up in patients with high risk facial pBCC.

RESUMEN

BACKGROUND AND OBJECTIVES: Childhood hemangioma is the most common soft tissue tumor of infancy, occurring in 10% of children younger than 1 year old. Ten percent of these infantile hemangiomas involute yearly without intervention. Treatment with the pulsed dye laser (PDL) is the criterion standard for treating vascular lesions. It is well established as the most effective, safest treatment for port-wine stains. Previous studies of the use of PDL treatment in superficial hemangioma showed inconsistent results. Main objectives were to compare the efficacy and adverse effects of PDL treatment with those of observation in the treatment of superficial hemangiomas. Parental quality of life was also assessed. MATERIALS AND METHODS: This was a prospective, randomized, controlled trial in which we enrolled 22 infants aged 1.5 to 5 months old with early hemangiomas with a maximum diameter of 5 cm. We assigned the infants to PDL treatment (n = 11) or observation (n = 11), and followed up until the age of 1 year. Patients in the intervention group were treated using a 595-nm PDL (VBEAM, Candela Corp., Wayland, MA) with a 7-mm spot diameter, 30/10 to 40/10-ms epidermal cooling, a 7- to 15-J/cm(2) fluence range, and a pulse duration of 0.45 to 40.0 ms. During follow-up, color measurements were made (Colori meter; Minolta, Tokyo, Japan), and surface area and echo depth of the hemangioma were determined. RESULTS: No significant differences were seen between the groups at time of inclusion or at the age of 1 year in echo depth (p = .66) or surface area (p = .62). Results were significant for color difference (p = .03) between PDL treatment and observation. Cosmetic outcome judged by an independent panel consisting of a dermatologist, physician assistant, dermatology resident, dermatology nurse, and plastic surgery resident was significantly better in the PDL treatment group (46%) than in the observation group (18%) (p = .006). CONCLUSIONS: Pulsed dye laser is only to be considered as an alternative treatment up to the age of 6 months, at which time parents and physicians consider cosmetic outcome to be a relevant factor, but laser therapy plays a major role in the treatment of residual lesions at older ages.

RESUMEN

Several methods have been used in wound closure after coronary artery bypass grafting (CABG). In this study, the safety and efficacy of one of these methods, Steri-Strip S is compared with the traditional intracuticular suture method. Eighty-one patients undergoing CABG were prospectively randomized into two groups according to the method of skin closure: Steri-Strip S group and traditional suture group. Comparison between the two methods was done with regards to the length of the wound and the time needed to close it. The median closure time with Steri-Strip S was 5.45+/-3.35 min vs. 7.53+/-3.41 min in the suture group. A pain score of >or=6 at the first postoperative day was found in 30% of the patients in the suture group vs. 14% of the patients in the Steri-Strip S group (P=0.07). Cosmetic evaluation showed a non-significant difference in the linear visual analogue score in favor of Steri-Strip S group compared to the intracuticular suture group (73.1 vs. 70.1) (P=0.07). Steri-Strip S is a fast, safe alternative for wound closure of the sternotomy incision and graft harvesting site. A larger study is needed to establish the potential beneficial effect of Steri-Strip S on wound infection prevention.

RESUMEN

BACKGROUND: Basal-cell carcinoma (BCC) is the most common form of skin cancer and its incidence is still rising worldwide. Surgery is the most frequently used treatment for BCC, but large randomised controlled trials with 5-year follow-up to compare treatment modalities are rare. We did a prospective randomised controlled trial to compare the effectiveness of surgical excision with Mohs' micrographic surgery (MMS) for the treatment of primary and recurrent facial BCC. METHODS: Between Oct 5, 1999, and Feb 27, 2002, 408 primary BCCs (pBCCs) and 204 recurrent BCCs (rBCCs) in patients from seven hospitals in the Netherlands were randomly assigned to surgical excision or MMS. Randomisation and allocation was done separately for both groups by a computer-generated allocation scheme. Tumours had a follow-up of 5 years. Analyses were done on an intention-to-treat basis. The primary outcome was recurrence of carcinoma, diagnosed clinically by visual inspection with histological confirmation. Secondary outcomes were determinants of failure and cost-effectiveness. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN65009900. FINDINGS: Of the 397 pBCCs that were treated, 127 pBCCs in 113 patients were lost to follow-up. Of the 11 recurrences that occurred in patients with pBCC, seven (4.1%) occurred in patients treated with surgical excision and four (2.5%) occurred in patients treated with MMS (log-rank test chi(2) 0.718, p=0.397). Of the 202 rBCCs that were treated, 56 BCCs in 52 patients were lost to follow-up. Two BCCs (2.4%) in two patients treated with MMS recurred, versus ten BCCs (12.1%) in ten patients treated with surgical excision (log-rank test chi(2) 5.958, p=0.015). The difference in the number of recurrences between treatments was not significant for pBCC, but significantly favoured MMS in rBCC. In pBCC, Cox-regression analysis showed no significant effects from risk factors measured in the study. In rBCC, aggressive histological subtype was a significant risk factor for recurrence in the Cox-regression analysis. For pBCC, total treatment costs were euro1248 for MMS and euro990 for surgical excision, whereas for rBCC, treatment costs were euro1284 and euro1043, respectively. Dividing the difference in costs between MMS and surgical excision by their difference in effectiveness leads to an incremental cost-effectiveness ratio of euro23 454 for pBCC and euro3171 for rBCC. INTERPRETATION: MMS is preferred over surgical excision for the treatment of facial rBCC, on the basis of significantly fewer recurrences after MMS than after surgical excision. However, because there was no significant difference in recurrence of pBCC between treatment groups, treatment with surgical excision is probably sufficient in most cases of pBCC.

RESUMEN

BACKGROUND AND OBJECTIVES: Many treatment modalities exist for actinic keratoses (AK). Topical 5-fluorouracil (5-FU) has been one of the standard treatments. Laser resurfacing is a more recent treatment option. In the literature prospective randomized studies comparing these treatments are lacking. STUDY DESIGN/PATIENTS AND METHODS: Prospective randomized study to compare topical 5-FU with Er:YAG laser resurfacing. Fifty-five patients with multiple AK on the scalp and or the face were included. Clinical and histopathological evaluation took place at 3, 6, and 12 months after treatment. RESULTS: At 3, 6, and 12 months after treatment, there were significantly less recurrences in the laser group compared to the group of patients treated with 5-FU. Side effects did occur more frequently in the laser group, especially erythema and hypopigmentation. CONCLUSIONS: Compared to treatment with topical 5-FU, Er:YAG laser resurfacing is more effective regarding recurrence rates. Although significantly more side effects occur, laser resurfacing is a useful therapeutic option especially in patients with widespread AK.

RESUMEN

BACKGROUND: Diffuse widespread actinic keratoses are difficult to treat, have a tendency toward higher recurrence rates, and therefore require ablative treatment. Laser resurfacing is one of the treatment modalities that can treat whole surface areas. OBJECTIVE: To evaluate patients who underwent laser resurfacing for widespread actinic keratoses with long-term follow-up for recurrence rates, time until new lesions occur, and the most common side effects. METHODS: Retrospective case-control study from 25 patients who underwent laser resurfacing for widespread actinic keratoses on the scalp, forehead, or full face at our department. Follow-up varied from 7 to 70 months. Recurrence rates, adverse effects, and improvement were analyzed through chart analysis. RESULTS: The mean average follow-up was 39 months. Forty-four percent of the patient shad no recurrence during the time period. Fifty-six percent of the patients developed new lesions after treatment but only a few. Of the recurrences, 20% occurred within 1 year and 36% occurred after 1 year. The most common short- and long-term side effects were infections (12%), hypopigmentation (48%), hyperpigmentation (8%), acne (12%), milia (12%), scar formation (8%), and atrophic and/or easily bruised skin (20%). CONCLUSION: Laser resurfacing is an effective treatment modality for diffuse widespread actinic keratoses with long-term recurrence-free intervals.

RESUMEN

BACKGROUND: Rates of recurrence of facial basal-cell carcinoma are consistently lower after Mohs' micrographic surgery (MMS) than after other treatments, such as surgical excision (SE). However, MMS is more time-consuming and therefore more expensive than SE. We investigated the types of facial basal-cell carcinomas in which MMS was more effective than SE. METHODS: 408 primary and 204 recurrent facial carcinomas (374 and 191 patients, respectively) were analysed separately in this prospective randomised study. Patients were assigned SE or MMS (each 204 primary, 102 recurrent), and received treatment at two hospitals in the Netherlands. The primary outcome was recurrence of carcinoma. Analysis was by intention to treat. FINDINGS: Of the basal-cell carcinomas included in the trial, 397 primary (198 MMS, 199 SE) and 201 recurrent (99, 102) tumours were actually treated. Of patients with primary carcinomas, 21 had both MMS and SE on different tumours. Nine with recurrent carcinomas had both treatments on different skin tumours. 66 primary and 13 recurrent carcinomas were lost to follow-up. Of the primary carcinomas, five (3%) recurred after SE compared with three (2%) after MMS during 30 months of follow-up. Of the recurrent carcinomas, three (3%) recurred after SE and none after MMS during 18 months of follow-up. Four recurrent carcinomas randomly assigned to the SE group were treated with MMS. Although both differences favoured MMS, they were not significant (primary, difference 1% [95% CI -2.5% to 3.7%], p=0.724; recurrent, 3.2% [-2.0% to 5.0%], p=0.119). Total operative costs of MMS were higher than those of SE (primary 405.79 Euros vs 216.86 Euros, recurrent 489.06 Euros vs 323.49 Euros; both p<0.001). INTERPRETATION: No definitive conclusion on recurrence rates of primary or recurrent basal-cell carcinomas is yet possible. Although recurrence rates were lower after MMS than after SE, the differences were not significant.

RESUMEN

BACKGROUND: Actinic keratosis is an exceedingly common premalignant lesion that can develop into squamous cell carcinoma. There is an increasing prevalence of actinic keratosis with increasing age. Numerous treatment options are available for the treatment of actinic keratosis on the scalp. Although we know that atrophic skin heals slowly, one should be careful but should not hesitate to treat. OBJECTIVE: We present three patients with widespread actinic keratotic lesions on the atrophic bald scalp who received different treatments. METHODS: Patient 1 was treated with medium-depth chemical peel, patient 2 with cryopeel, and patient 3 with CO2 laser resurfacing. In all patients, the entire surface area was treated. RESULTS: Despite the different treatment methods used, all three patients had severely delayed wound healing as a complication. Remarkably, all patients had a prolonged period of re-epithelialization. CONCLUSION: Care has to be taken in patients with widespread actinic keratosis on the atrophic bald scalp when treating the entire surface area regardless the treatment modality.
