Efficacy of a simple left atrial procedure for chronic atrial fibrillation
in mitral valve operations.
Annals of Thoracic Surgery, 1997 Apr, 63(4):1070-5.
(UI: 97248321)
Abstract: BACKGROUND: We have devised a simple surgical procedure to be
performed on the posterior wall of the left atrium for the treatment of
chronic atrial fibrillation (AF) associated with mitral valve disease. The
effectiveness of this procedure for serial mitral valve operations was then
evaluated. We postulated that chronic AF associated with mitral valve
disease could be attributable to a distended left atrium. The refractory
period of the distended left atrium was significantly shorter in the left
posterior atrial wall, especially at the base of the left atrial appendage
and at the orifice of the left posterior pulmonary vein. We hypothesized
that the left posterior atrial wall with its shorter fibrillatory cycle
length would act as a driver for maintaining the AF, and therefore,
surgical ablation of this critical area in the left atrium could terminate
the chronic AF. METHODS: The surgical patients were divided into two
groups. In group 1 (control group), 15 patients with chronic AF were
operated on by the mitral valve procedure only. In group 2, 36 patients
underwent this procedure in combination with a concomitant mitral valve
operation. The disappearance rate of the AF was estimated by
electrocardiography, and atrial function was estimated by transthoracic and
transesophageal echocardiography. RESULTS: The chronic AF had been reduced
significantly or eliminated at discharge in 4 of 15 patients (26.7%) in the
group 1, versus 31 of 36 patients (86%) in group 2 (p < 0.05). In group 2,
29 of the 31 patients (94%) whose AF had disappeared recovered the atrial
kick of their right atrium, and 21 patients (22/31; 71%) recovered the
atrial kick of their left atrium. CONCLUSIONS: Surgical ablation of the
posterior wall of the left atrium was effective in the treatment of chronic
AF associated with mitral valve disease. This simple procedure could
restore a sinus rhythm and also recovered atrial systolic function. We
conclude that the left atrium may act as a driver for sustaining AF in
mitral valve disease.

Female genital tract papillomavirus in conjunctival papillomas of infancy.
American Journal of Ophthalmology, 1997 Apr, 123(4):551-2.
(UI: 97255158)
Abstract: PURPOSE: To show the association between conjunctival papillomas
present during infancy and maternal infection with human papillomavirus.
METHOD: Case report of conjunctival papillomas occurring in an infant born
to a mother with a human papillomavirus infection of the vulva during
pregnancy. RESULT: The infant developed conjunctival papillomas caused by
human papillomavirus of the female genital tract. CONCLUSIONS: Conjunctival
papillomas present during infancy may be caused by vertical transmission of
the human papillomavirus from mother to infant during delivery. Mothers of
infants with conjunctival papillomas should be examined for diseases
associated with human papillomavirus.

Focal therapy for prostate cancer 1996: maximizing outcome.
Urology, 1997 Mar, 49(3A Suppl):84-94.
Pub type: Journal Article; Review; Review, Tutorial.
(UI: 97237005)
Abstract: OBJECTIVES: To summarize improvements in patient selection and the
results of focal therapy for the management of localized prostate cancer.
METHODS: A contemporary series of patients managed with wide surgical
excision, radiation therapy (three-dimensional conformal radiation,
interstitial radiation, and charged-particle or proton therapy), and
cryo-therapy were reviewed. RESULTS: We used preoperative cancer grade,
transrectal ultrasound, and serum prostate-specific antigen (PSA) in all
patients, and cross-sectional imaging and bone scans in selected patients
to allow for reasonably accurate cancer staging and selection of patients
most likely to be cured by radical prostatectomy or radiation. In patients
with extracapsular extension of prostate cancer, wide surgical excision and
achievement of a clear surgical margin had therapeutic value. Newer
radiation techniques resulted in a higher likelihood of prostate cancer
control than previous techniques. Cryotherapy for patients with stages T1
through 3 prostate cancer was associated with a posttreatment undetectable
PSA rate of 48% and a positive biopsy rate of 23%. CONCLUSIONS: Patients
with organ-confined and, therefore, curable prostate cancer can be
identified. Well-performed radical prostatectomy, radiation, and
cryotherapy are alternative treatments for the management of localized
prostate cancer.

Effect of antifreeze proteins on frozen primary prostatic adenocarcinoma
cells.
Urology, 1997 Mar, 49(3):421-5.
(UI: 97225838)
Abstract: OBJECTIVES: Recent studies show that prostate adenocarcinoma cells
can survive cryosurgery and that cell destruction depends on the specific
thermal parameters used during freezing. The goal of this preliminary study
is to determine whether certain chemical compounds, known as antifreeze
proteins, can induce complete human primary prostatic adenocarcinoma cell
destruction by freezing, regardless of the thermal parameters used. The
study also examines the mechanism by which antifreeze proteins bring about
cell destruction. METHODS: Antifreeze proteins were added to solutions
containing human primary prostatic adenocarcinoma cells. The cells were
frozen with controlled thermal parameters using a directional
solidification apparatus attached to a light microscope. Cell viability was
determined after thawing as a function of antifreeze protein concentration
and cooling rate during freezing. RESULTS: The dose response study shows
that for all the cooling rates tested, 10-mg/mL solutions of antifreeze
protein cause the complete destruction of human primary prostatic
adenocarcinoma cells frozen to a temperature at which, without these
proteins, the cells survive freezing. Light microscopy shows that the
lethal effect of the antifreeze proteins is related to the formation of
intracellular ice in the frozen cells. CONCLUSIONS; This preliminary study
has demonstrated that antifreeze proteins have the ability to generate
complete destruction of prostatic adenocarcinoma cells frozen to high
subzero temperatures irrespective of the cooling rates used during
freezing. This suggests that introducing antifreeze proteins into
undesirable tissues prior to freezing may increase the efficacy and the
control over tissue destruction by cryosurgery.

Surgery for primary and metastatic colorectal cancer.
Gastroenterology Clinics of North America, 1997 Mar, 26(1):103-28.
Pub type: Journal Article; Review; Review, Tutorial.
(UI: 97187349)
Abstract: Carcinoma of the colon and rectum currently ranks as the second
leading cause of death from cancer in the United States. Surgery remains
the cornerstone of treatment for colorectal cancer but has inherent
limitations imposed by the biology and stage of the tumor and its location.
Ultimately, 50% of patients who undergo curative resection develop local,
regional, or widespread recurrence. These statistics have remained
relatively constant over several decades despite improved methods of early
diagnosis and surgical treatment but may change as new multimodality
treatment regimens are developed and clinically evaluated. This article
summarizes the surgical management of colorectal cancer and discusses
issues pertaining to postoperative surveillance and the diagnosis and
management of local or widespread cancer recurrence.

[Congenital ectopic junctional tachycardia: long-term remission after
cryoablation of the bundle of His].
Revista Espanola de Cardiologia, 1997 Mar, 50(3):211-3.
Language: Spanish.
(UI: 97243241)
Abstract: Congenital junctional ectopic tachycardia is an uncommon and
potentially fatal arrhythmia that does not usually respond to medical
therapy. We report a two month old infant with severe ventricular failure.
The diagnosis was confirmed by electrophysiologic study. She underwent
endocardial cryoablation of the His bundle during extracorporeal
circulation and a ventricle epicardial-lead pacemaker was implanted. Eight
years later the patient is still symptom-free without needing medical
treatment.

Actinic cheilitis. A treatment review.
Dermatologic Surgery, 1997 Jan, 23(1):15-21.
Pub type: Journal Article; Review; Review, Tutorial.
(UI: 97261335)
Abstract: BACKGROUND: Actinic cheilitis is a common premalignant condition,
significant for symptoms and potential development into invasive squamous
cell carcinoma. Multiple methods of treatment have been reported for this
entity. OBJECTIVE: The purpose of this article is to review and compare the
accepted treatment modalities reported for actinic cheilitis. METHODS: The
English language literature was reviewed for treatment options, efficacy
and adverse effects. RESULTS: Cryosurgery, electrocautery, 5-fluorouracil,
carbon dioxide laser, and scalpel vermilionectomy were all clinically
effective. All therapies, with the exception of chemical peeling, appear to
have a low clinical failure rate. Histological clearance of disease was
demonstrated in carbon dioxide laser-treated patients. 5-Fluorouracil
failed to achieve complete removal of histologic dysplasia. The carbon
dioxide laser may be associated with less scarring and an improved cosmetic
outcome in comparison with the scalpel vermilionectomy. CONCLUSION: Focal
actinic cheilitis is easily treated with cryosurgery or electrosurgery.
Extensive actinic cheilitis requires 5-fluorouracil, carbon dioxide laser,
or scalpel vermilionectomy for adequate treatment. The carbon dioxide laser
offers some advantages over scalpel vermilionectomy.

Soft-tissue uptake of technetium-99m-MDP after prostate cryoablation.
Journal of Nuclear Medicine, 1997 Apr, 38(4):525-8.
(UI: 97252737)
Abstract: Prominent soft-tissue uptake of 99mTc-methylene diphosphonate (MDP)
within the prostate bed was found after cryoablation for prostate
carcinoma. CT, MRI and sonographic studies demonstrated liquifactive
necrosis of the prostate bed. The probable etiology for 99mTc-MDP uptake in
this case is necrosis with subsequent neovascular hyperemia and microscopic
calcium deposits. Three-phase scintigraphy with 99mTc-MDP appears to be
useful for localizing the extent of soft tissue inflammation and necrosis.

The mechanism of intraocular pressure rise during cyclocryotherapy.
Investigative Ophthalmology and Visual Science, 1997 Apr, 38(5):1012-7.
(UI: 97267667)
Abstract: PURPOSE: Intraocular pressure (IOP) spikes that occur during
cyclocryotherapy for advanced glaucoma may further injure the already
damaged glaucomatous optic nerve and be responsible for visual impairment
that may occur after this treatment. The authors investigated the mechanism
of pressure rise to see whether it can be avoided and thus prevent further
optic nerve injury. The authors postulated that intraocular ice forms
during the cryo procedure and causes the pressure changes. METHODS:
Intraocular pressure was monitored using a pneumatonometer during 15
cryocycles of four patients with advanced glaucoma and 21 cryocycles of
five normal rabbits. A simple thermal model was developed to analyze the
relation between volume expansion and pressure rise in the eye. The
physical effect of freezing rabbit eye structures was investigated in
vitro. RESULTS: The largest pressure spikes observed during the cryocycles
in this work were increases of 32 mm Hg for humans and 25 mm Hg for
rabbits. The mean value of the IOP immediately before and after the cryo
freezing stage was 53 +/- 1 and 68 +/- 2 mm Hg, respectively, for humans
and 22 +/- 1 and 32 +/- 1 mm Hg for rabbits. The parameters of the thermal
model were determined from the observed IOP spikes. Calculated thaw times
were consistent with measured times for return to precryo IOPs. In vitro
cryoapplication (rabbit eye) showed the formation of an ice ball internal
to the eye. CONCLUSIONS: Volumetric increase of the intraocular content
related to the formation of an ice ball in the eye, is the mechanism of
pressure spikes during cyclocryotherapy. Because this complication is
unavoidable, other cyclodestuctive methods may be more prudent,
particularly in patients with advanced glaucoma.

Prostate-specific antigen after cryosurgical ablation of the prostate.
Defining the appropriate response.
Urologic Clinics of North America, 1997 May, 24(2):415-20.
(UI: 97271288)
Abstract: The ability of prostate-specific antigen (PSA) to predict long-term
cure after cryotherapy for localized prostate cancer is not known because
experience with this treatment modality is limited; however, it appears
that a PSA value of 0.5 ng/mL or less at 6 months or longer after
cryotherapy is associated with a high probability of a negative
post-treatment biopsy (greater than 95%). An undetectable PSA (less than
0.1 ng/mL) 3 months after the procedure is associated with a likelihood of
a negative biopsy at 6 months and low, stable PSA levels up to 2 years.

The effectiveness of cryoendoscopic treatment for tubal infertility.
Journal of the American Association of Gynecologic Laparoscopists, 1995 Feb,
2(2):187-91.
(UI: 97203386)
Abstract: Seventy-three women experienced bilateral proximal tubal occlusion
caused by adhesions or polyps arising from the uterotubal junction in at
least one tube. There were no other identifiable causes of infertility. All
patients were treated with cryosurgery, which restored tubal patency in 61
(83.6%). Of 45 women with restored patency, who were followed 6 to 12
months, 20 (27.4% of 73) conceived and 16 (21.9%) delivered viable babies.
