Outflow uropathy: occupational disorder?

This paper alerts physicians, health care workers, and employers to a probable connection between voluntary, infrequent voiding and urinary dysfunction. The dysfunction includes abnormal uroflow patterns, increased urethral resistance, abnormal post-void residuals, chronic trigonitis, and urethrovesical inflammatory polyps. A review of intermittent uroflow and obstructive uroflow patterns reveals that all females in this study worked long hours without voiding.

A unique cause of unconscious urinary incontinence.

The authors present a case of a healthy 55-year-old woman with a 1-year history of vaginal malodor and perineal dampness. A pyridium (phenazopyridine) pad test revealed a well-defined stain area no greater than 3 cm. Cystoscopic examination revealed multiple multilobulated polypoid neoplasms, which we feel probably represent pedunculated hemangiomas.

Clip appendectomy.

The clip appendectomy is an alternative to the classical suture appendectomy. The use of a new polymer clip facilitates this technique. During pelvic reconstructive surgery an appendectomy may be indicated when suspected appendiceal pathology (such as endometriosis) could adversely affect the surgical outcome.

Analysis of electronically pulsed versus quasi-continuous wave carbon dioxide lasers in an animal model.

In this study we sought to compare laser tissue interaction in both the quasi-continuous waveform and electronically pulsed waveform of the carbon dioxide laser. An intramode analysis of the electronically pulsed form (at 350 and 650 pulses per second) was also undertaken. Intraperitoneal laser incisions were made on New Zealand white female virginal rabbits and tested at days 0, 5, 15, and 20.

Application of the CO2 laser to infertility surgery.

In addition to use of the CO2 laser in gynecologic surgery for the treatment of pelvic, vaginal and vulvar neoplasms, it has been more recently applied to the treatment of infertility. The advantages afforded by the laser over conventional techniques are discussed. The authors' clinical experience in the surgical treatment of infertility, with emphasis on endometriosis and microtubal surgery, are described, and use of the new electro-pulsed laser in infertility surgery is evaluated.

Cold light sources. Are they really cold?

Two light sources used in laparoscopy, both in the photo mode, proved capable of burning a hole in a standard paper surgical drape in less than five seconds. The relationship between power (in watts) and dial settings is not linear. Both of these sources have a maximum power density of 5.

Carbon dioxide laser and electrosurgical wound study with an animal model: a comparison of tissue damage and healing patterns in peritoneal tissue.

This study was designed to compare the effect of wound healing after the use of the carbon dioxide laser and the electrosurgical unit on the peritoneal mesothelium of the New Zealand white rabbit. The biophysical parameters were held constant and identical in both groups. The effects were compared in terms of tissue damage, adhesion formation, and healing time.

Surgical management of endometriosis with the carbon dioxide laser.

This study was designed to evaluate the efficacy of reconstructive microsurgery with the carbon dioxide laser for the treatment of infertile women suffering from endometriosis. One hundred and eight women evaluated for infertility and endometriosis underwent reconstructive microsurgery with the carbon dioxide laser. All cases were classified in accordance with the American Fertility Society's classification.

The use of the carbon dioxide laser in the management of condyloma acuminatum with eight-year follow-up.

This paper relates our comprehensive treatment and follow-up of 242 women with condyloma acuminatum over an 8-year period. Laser treatments were carried out at an average power density of 800 W/cm2. Thirty-five patients received a general anesthetic prior to treatment.

Colposcopy and the CO2 laser for treatment of cervical intraepithelial neoplasia. An analysis of seven years' experience.

We performed a study to determine the efficacy of laser therapy for the three grades of cervical intraepithelial neoplasia. Two hundred ninety-two patients were studied. Over 90% of the cases occurred in women between 20 and 30 years of age.

Microsurgery of the fallopian tube with the carbon dioxide laser: analysis of 230 cases with a two-year follow-up.

Between September 1979 and December 1982, 230 cases of tubal reconstructive surgery were followed for 2 years. An analysis of these cases showed 75% to have had more than one procedure performed. There were 91 pregnancies in this group.

Comparative gross and histological study of the effects of scalpel, electric knife, and carbon dioxide laser on skin and uterine incisions in dogs.

This study concerns the gross histological effects of scalpel, electric knife, and carbon dioxide laser incisions on skin and uterine tissue in dogs. Tissue studies comparing the carbon dioxide laser with the scalpel and electric knife have frequented the literature. However, a gross and histological comparison specifically involving uterine tissue is not presently known to have been reported.

Carbon dioxide laser treatment of vaginal adenosis in DES-exposed offspring: a prospective study.

Seventy-nine patients with history and physical findings characteristic of antenatal DES exposure were randomly divided into two groups. Fourty-four DES-exposed offspring had their vaginal adenosis treated with the carbon dioxide laser (group I), and the remaining 35 DES-exposed offspring (group II) did not receive any specific treatment for this condition. Additionally, the 79 DES-exposed offspring were compared to an age-matched control population (group III).

Linear and nonlinear effect of the argon laser on a fallopian tube animal model.

Rabbit fallopian tubes were used as models to demonstrate the delayed effects of the argon laser wavelength on tissue. Power density, energy density, and velocity were all variables in the experiment. Three groups of ten rabbits were sacrificed two at a time, on days 0, 5, 10, 15, and 20.

Analysis of plume emissions after papovavirus irradiation with the carbon dioxide laser.

This study was undertaken to evaluate potential inhalation hazards to operating room personnel after irradiation of tumors with the carbon dioxide laser. Cellular debris was analyzed for viability using labeled nucleotides and labeled glucose. In this way the plume was investigated for the presence of material with oncogenic potential.

Microsurgery of the fallopian tube with the carbon dioxide laser: eighty-two cases with follow-up.

In 1974 the carbon dioxide laser was adapted to the operating microscope for reconstructive pelvic surgery and the first 15 cases of laser tubal microsurgery were performed. The instrumentation and techniques were refined. A protocol was designed to test the efficacy of this surgical modality, and a new study was begun in 1980.

Reliability of histopathologic diagnosis of cervical intraepithelial neoplasia.

A study was designed to measure the inter-pathologist consistency of histopathologic diagnosis of cervical intraepithelial neoplasia (CIN) among four pathologists. Intra-pathologist reliability over time was also determined. Between-pathologist comparisons resulted in agreement only 50% of the time; however, 81% of pairs were within one CIN grade of each other.

Carbon dioxide laser management of cervical intraepithelial neoplasia.

In this report we describe the use of the carbon dioxide laser for the outpatient management of cervical intraepithelial neoplasia (CIN). A comparison of treatment effectiveness for different grades of CIN is also included. Two hundred fifty-six cases were evaluated by colposcopy, cytology, and histopathology, treated by at least 5 to 6 mm of laser vaporization, and followed up for an average of 10.
