Heterotopic gastric mucosa in the rectum.

A case of an ulcer of the rectum in a 20-year-old patient with rectal pain and rectal bleeding is reported. Histological examination of the endoscopic biopsy showed the presence of gastric or fundic mucosa. The patient was treated with Cimetidine and alkaline drugs, with positive results. Ulcer cicatrization was verified at subsequent endoscopic examinations, and biopsies obtained at different levels of the colon revealed a normal histological picture.

Effectiveness of intraoperative L.E.S. pressure measurement during Nissen-Rossetti fundoplication.

A study was made to evaluate the effectiveness of Lower Esophageal Sphincter Pressure (L.E.S.P.) measurement during Nissen antireflux procedure. Thirty-five patients affected by reflux esophagitis were submitted preoperatively to X-ray examination, endoscopy and esophageal biopsy, intraluminal esophageal manometry and 24 hour pH monitoring of the distal esophagus. Intraoperative measurement of L.E.S.P. was performed before and after Nissen fundoplication. In 30 patients a follow-up (average 32 months after surgery) was performed by clinical, radiographic and pH (24 hour monitoring) evaluation. Complete relieve of symptoms was obtained in patients showing a L.E.S.P. between 25 and 30 mm Hg after fundoplication. Symptoms of "post-fundoplication syndrome" were observed in two subjects with a L.E.S.P. more than 30 mm Hg. On the other hand, one patient with sphincteric pressure of less than 25 mm Hg suffered from postoperative recurrence of gastroesophageal reflux. The effectiveness of intraoperative L.E.S.P. measurement to verify the adequacy of Nissen fundoplication is emphasized. It is also postulated that good results can be obtained when surgical repair is associated with a range of intraoperative sphincteric pressure between 25 and 30 mm Hg.

[Polycardiography in the diagnosis of latent cardiac insufficiency].

A group of heart patients and another group of healthy subjects have been studied and their systolic intervals (PEP-LVET - PEP/LVET ratio and the telediastolic index) evaluated using the mechanocardiographic system. In both long-standing and recent heart patients, the parameters studied showed significant deviations from the norm. These were even more marked after exercise on the ergonometer bicycle. Acute doses of digitalis reduced deviations from the norm observed under basal conditions and after exercise. Polycardiography, it is concluded, assists in the gathering of extremely valuable information about cardiac performance in relation to latent cardiac insufficiency. Especially useful information can be deduced from PEP indications and from the PEP/LVET ratio. The use of digitalis is suggested for physically active post-infarction subjects in order to give greater tolerance of physical exercise. The concept of long-term polygraphic studies as part of out-patient follow-ups on such patients is outlined.
