PROBLEM: Abstract: Cryosurgery is now a widely accepted modality for the treatment of basal cell carcinomas. This article presents a practical approach to using cryosurgery for this purpose in the dermatologist's office. Understanding the cryobiologic basis of cryosurgery is a prerequisite. Aspects of treatment covered include selection and use of appropriate equipment, indications and contraindications for specific tumors, preoperative preparation, various treatment technics with clinical and instrumental depth-dose monitoring, postoperative care, cure rate, and cosmetic and functional end results. The overall results obtained by cryosurgery compare favorably with those obtained by other modalities. Cryosurgery is the treatment of choice for some basal cell carcinomas and a satisfactory alternate treatment for others.
Which is the apt title for the abstract? option1: Cryosurgery of basal cell carcinoma. option2: Inheritance pattern and clinical response to splenectomy as a reflection of erythrocyte spectrin deficiency in hereditary spherocytosis.

SOLUTION: Cryosurgery of basal cell carcinoma.

PROBLEM: Abstract: Methods for endoscopic retrograde cholangiography (ERC) and endoscopic papillotomy (EPT) in patients with Billroth-II operations are described, and experience with their use during the last four years (since 1980) is presented. Endoscopic retrograde cholangiopancreatography was successful in 134 of 147 patients (92%) and endoscopic papillotomy was successful in 46 of 50 patients. The described methods were used in two different hospitals by two different endoscopists and there was no difference in the results. We conclude that patients with a Billroth-II operation may undergo endoscopic diagnostic as well as therapeutic procedures with a high rate of success, with similar results as in ordinary patients and with no greater risk of complications.
Which is the apt title for the abstract? option1: Endoscopic retrograde cholangiography and endoscopic papillotomy in patients with a previous Billroth-II resection. option2: Leads from the MMWR. Congenital syphilis--United States, 1983-1985.

SOLUTION: Endoscopic retrograde cholangiography and endoscopic papillotomy in patients with a previous Billroth-II resection.

PROBLEM: Abstract: A patient with a mobile schwannoma of the cauda equina is described. There was considerable discrepancy between the localization of the tumor at myelography and the findings at both initial surgery and repeat myelography, confirmed by definitive surgery. Such mobility is rare, but should be kept in mind when surgery is performed for a tumor of the cauda equina.
Which is the apt title for the abstract? option1: Elusive tumor of the cauda equina. Case report. option2: Rarity of cesarean delivery in cases of juvenile-onset respiratory papillomatosis.

SOLUTION:
Elusive tumor of the cauda equina. Case report.
