background. Epidermal nevi have been notoriously difficult to treat due to their large size and often conspicuous location. Variable results have been obtained with different laser treatments, and scarring and/or incomplete removal is typical after excisional or other destructive modalities. objective. To outline the successful use of a short-pulsed CO2 laser in the long-term eradication of epidermal nevi in three patients. methods. Three females (ages 15,19) presented with extensive grouped verrucous papules and plaques on the face, trunk, and extremities. A pulsed CO2 laser was used to vaporize the lesions using a 500 mJ pulse energy, 3 mm spotsize, and 7 watts of power. results. All lesions healed without incident. No lesional recurrence was observed 10 to 13 months after treatment except in one small area on the ankle in one patient. conclusions. Carbon dioxide laser vaporization of epidermal nevi provides good clinical effect and offers unique advantages for the treatment of these lesions, including effective intraoperative hemostasis with excellent lesional visualization. It is also possible to treat widespread areas in one laser treatment session. While the results of this series clearly show the benefit of CO2 laser treatment, epidermal nevi may not always respond so favorably, due in part to the variability in their depths of involvement.

Improvement of Dermatochalasis and Periorbital Rhytides With a High-Energy Pulsed CO2 Laser: A Retrospective Study

DERMATOLOGIC SURGERY, Issue 4 2004
Tina S. Alster MD
Background. Upper eyelid dermatochalasis is typically treated with excisional blepharoplasty. The role of the CO2 laser previously had been confined to that of a vaporizing, incisional, or hemostatic tool. Over the past several years, however, ablative CO2 laser skin resurfacing has been popularized as an adjunctive treatment to blepharoplasty to minimize periorbital rhytides through its vaporizing as well as skin-tightening action. Objective. To evaluate the safety and efficacy of a high-energy pulsed CO2 laser as a stand-alone treatment for dermatochalasis and periorbital rhytides. Methods. Sixty-seven patients (skin phototypes I,IV) with mild-to-severe upper eyelid dermatochalasis and periorbital rhytides received periocular CO2 laser skin treatment. Global assessment scores of dermatochalasis and rhytides were determined by a side-by-side comparison of periocular photographs preoperatively and 1, 3, and 6 months postoperatively. In addition, caliper measurements of upper eyelids before and 1, 3, and 6 months after treatment were obtained. Results. Both dermatochalasis and periorbital rhytides were significantly improved after periocular CO2 laser skin resurfacing. Patients with more severe dermatochalasis and rhytides showed greater improvement after CO2 laser treatment than did those with mild or moderate involvement. Side effects were limited to erythema and transient hyperpigmentation. No scarring, hypopigmentation, or ectropion were observed. Conclusions. Periocular skin resurfacing with a CO2 laser can safely and effectively improve upper eyelid dermatochalasis and periorbital rhytides. [source]

Partial laryngectomy for recurrent glottic carcinoma after radiotherapy

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 2 2005
Aniel Sewnaik MD
Abstract Background. Early laryngeal cancer is treated with surgery or radiotherapy. A partial laryngectomy instead of a total laryngectomy can be used for treating patients with radiation failures. Methods. Patients were grouped by the two types of partial laryngectomies we performed: group I, endoscopic laser surgery (n = 42); and group II, frontolateral partial laryngectomy (n = 21). Results. With CO2 laser treatment, 14 of 24 patients (no involvement of the anterior commissure) and eight of 18 patients (involvement of the anterior commissure) were cured. With the frontolateral partial laryngectomy, we achieved local control in 15 of 21 patients. Conclusions. If the surgeon is familiar with the different techniques of, and indications for, partial laryngectomy, this can be a good and satisfying treatment in selected patients with radiation failure for glottic cancer. © 2004 Wiley Periodicals, Inc.

Transoral carbon dioxide laser microsurgery for recurrent glottic carcinoma after radiotherapy

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 6 2004
Wolfgang Steiner MD
Abstract Background. Transoral laser microsurgery is successfully performed in the treatment of primary laryngeal carcinomas. Few publications deal with the application in patients with recurrent glottic carcinomas after radiation failure. Our study aims to review our experience with transoral laser microsurgery in these patients. Methods. Thirty-four patients with early and advanced recurrent glottic carcinoma after full-course radiotherapy (rT1, n = 11; rT2, n = 10; rT3, n = 10; rT4, n = 3) had CO2 laser treatment with curative intent between 1987 and 1998. Results. Twenty-four patients (71%) were cured with one or more laser procedures. In nine patients, recurrences could not be controlled by laser microsurgery: six patients underwent total laryngectomy and three palliative treatment. One patient received total laryngectomy because of chondronecrosis after laser treatment. With a median follow-up interval of 38.6 months, the 3-year and 5-year disease-specific survival was 86%. The overall 3-year survival rate was 74%; the corresponding 5-year survival rate was 53%. No major complications occurred. In three cases, temporary tracheostomy was needed. Conclusions. In early-stage and advanced-stage recurrent glottic carcinomas after radiotherapy, CO2 laser treatment can successfully be used as a curative organ-preserving procedure. Compared with salvage laryngectomy, results are superior with respect to preservation of laryngeal function. Great expertise is required, especially in resections of advanced-stage recurrent carcinomas. © 2004 Wiley Periodicals, Inc. Head Neck26: 477,484, 2004 [source]


Preventable but not prevented: the reality of cervical cancer,

JOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 5 2003
Usha B. Saraiya
Abstract Introduction: The incidence of invasive cervical cancer has decreased in the last 50 years in the developed countries substantially due to the use of routine pap smears. However, in the Asia,Oceanic region it continues to be high as screening programs are not established. Credit for starting cytology services in India goes to Professor P.N. Wahi of Agra. He became Founder President when about 34 cytologists got together in 1970 to form the Indian Academy of Cytologists. Since then cytology has spread through all parts of India. The Cytology Clinic in Cama & Albless Hospital was started in the same year. Since then over 100 000 women have been screened. Approximately 1200 cases of pre- and early cancers have been detected and treated. Since 1982 we are aware of the important role of human papillomavirus infection. We diagnose it by cytology and colposcopy and histology. Facilities for polymerase chain reaction, in-situ hybridization and other virology studies are not available to us. CO2 laser treatment is found particularly useful in multicentric human papillomavirus disease. Screening for the State of Maharashtra: Since 1984 we have planned for a screening program for our State. We have a population of 78.9 million. Approximately 15 million women in the age group of 35,64 years have to be screened. The health care infrastructure is good with 36 medical colleges and over 35 district hospitals. Screening is planned in phases. Trained personnel are the key to a successful program. In the final analysis, cervical cancer is not just a biomedical disease. It has socio-cultural and economic implications. [source]


CO2 laser treatment of Zenker's diverticula

CLINICAL OTOLARYNGOLOGY, Issue 4 2001
H.H.W. De Gier
Introduction. Evaluation of the results of endoscopic CO2 laser treatment of Zenker's diverticula. Methods. The records of all patients treated in the University Hospital Rotterdam between 1990 and 1996 using CO2 laser surgery or electrocautery (when CO2 laser was impossible because of technical reasons) for a Zenker's diverticulum were studied. Results. One hundred and eighty-three patients were treated for a Zenker's diverticulum, 179 times using CO2 laser and 42 times using electrocautery. In 29 patients, two or more treatments were needed. Twenty-five complications occurred, five severe and 20 mild. One patient died and in one patient the recurrent laryngeal nerve was damaged; the other patients made full recoveries. Conclusion. CO2 laser surgery is a safe and effective method of treatment for Zenker's diverticula. [source]
