Input: Consider Input: Abstract: Because female gymnasts as a group display higher than average incidences of stress-related pathologies of the lumbar spine, it was of interest to evaluate mechanical factors which are potential contributors. Lumbar hyperextension and impact forces were quantified for performances of five commonly executed gymnastics skills by four competitive collegiate women gymnasts. The skills performed were the front walkover, the back walkover, and the front handspring, the back handspring, and the handspring vault. Wielke's (1983) radius method was used to quantify lumbar curvatures from film data during normal relaxed standing postures and during subject performances of the five selected skills. A force platform was used to monitor vertical and lateral ground reaction forces at the terminations of the respective skill performances. Of the skills examined, the handspring vault produced the highest vertical and lateral impact forces, and the back handspring and back walkover required the greatest amounts of lumbar hyperextension. During the front and back walkovers and during the back handspring, maximum lumbar hyperextension occurred very close to the time that impact force was sustained by either the hands or the feet.

Input: Consider Input: Abstract: Eighteen cancer patients receiving intensive chemotherapy developed leukopenia, fever, dysphagia, and oropharyngeal soreness. Superficial esophageal ulceration suggestive of esophagitis was demonstrated by radiographic examination in 33% of the patients (5/15). Upper gastrointestinal endoscopy revealed superficial ulceration and white mucosal patches in all patients. There was no morbidity associated with the endoscopic procedures. Sixty-one percent of the patients (11/18) had monilia albicans cultured from the oropharyngeal cavity, and 50% (9/18) had monilia cultured from the esophageal lesions. The evolution of the esophagitis correlated well with the survival of the patients. The monilial esophagitis persisted in six patients who all died within 24 days of systemic moniliasis. After initial improvement five additional patients succumbed; three of them from severe fungal infection. There was resolution of the esophagitis in the remaining seven patients who survived longer. However, two of them had recurrent monilial esophagitis and succumbed to systemic candidiasis. The other five have remained free of esophagitis, their underlying malignancies have remained under control, and so far they have survived an average of one and a half years. Endoscopy is more accurate than radiography in detecting postchemotherapy esophagitis. This complication can be fatal, since it is often followed by systemic candidiasis.
Which is the apt title for the abstract? option1: Postchemotherapy esophagitis: the endoscopic diagnosis and its impact on survival. option2: Miniplate fixation of Le Fort I osteotomies.

Output: Postchemotherapy esophagitis: the endoscopic diagnosis and its impact on survival.

Input: Consider Input: Abstract: Mucus secreted by colorectal cancer differs in three respects from that produced normally: an overall reduction, a loss of O-acetyl substituents in sialic acid, and an increase in neutral mucin. Similar changes have been reported in apparently normal mucosa bordering colorectal cancer. "Normal" left sided colorectal mucosa from 32 patients with rectal cancer was studied. Each case was matched by age and sex to a patient with diverticular disease and a patient with irritable bowel syndrome. Twenty five patients with right sided cancer were matched to patients with Crohn's disease. Sections were stained with mild periodic acid Schiff (mPAS) (selectively stains N-acetyl sialic acid lacking in O-acetyl group) and other closely related techniques. Reactions were graded negative, weak, and intense. An intense reaction was found in 9% of cases; there was no difference between the various matched groups. Phenylhydrazine interposition failed to block the mPAS effect, indicating that a positive result was due to a deficiency of sialic acid with O-acetyl substituents rather than neutral mucin. Different staining patterns in left and right colon were probably due to differing ratios of total sialic acid:fucose. These findings indicate a hitherto unsuspected colorectal goblet cell sialomucin heterogeneity within the general population, but no association with neoplastic disease is apparent.
