[Treatment of residual choledochal calculi in patients with Kehr's T drainage: role and results of endoscopic sphincterotomy].
The results of sphincterotomy in the treatment of residual gallstones after cholecystectomy in a series of 62 patients, bearers of a T tube are reported. The mean time after surgery was 26.4 +/- 19.2 days. The procedure was technically successful in 59/62 (95.1%). Stones were passed spontaneously or were retrieved in 55/62 patients (88.7%). In four patients gallstones persisted in spite of sphincterotomy. All were operated with favorable results. Complications were observed in 4 patients (6.4%), without mortality. Sphincterotomy is a safe and relatively efficient technique in the treatment of cholecystectomized patients with residual gallstones and a T tube drainage.

[Endoscopic retrograde cholangiopancreatography in Mirizzi's syndrome].
Mirizzi's syndrome is characterized by compression and or stenosis of the common duct as a consequence of impaction of a stone in the gallbladder neck, the cystic duct and eventually by a cholecystobiliary fistula. Preoperative diagnosis is important to avoid iatrogenic injury of the biliary tree. We present two cases with Mirizzi's syndrome confirmed at operation in whom ERCP was done prior to the operation. In one of them the examination was diagnostic, while in the other, cystic duct compression and absence of the gallbladder image were the non-specific findings.

Community acquired pneumonia caused by Chlamydia pneumoniae strain TWAR in chronic cardiopulmonary disease in the elderly.
The role of Chlamydia pneumoniae in respiratory infections is controversial. Seroepidemiological studies in different countries have shown an incidence of around 50% of previous contact, whereas prospective studies only in the USA have detected 6-10% of C. pneumoniae in community acquired pneumonias; in a similar Swedish study no cases were detected. There have been no descriptions of this Chlamydia in Mediterranean countries. The acute antibody response indicative of recent infection is accepted if the microimmunofluorescence test shows a fourfold rise in antibody or a titer 1/6 or higher of the IgM fraction. Since the introduction of the microimmunofluorescence test in our hospital, we have detected 4 cases of pneumonia associated to TWAR antibody in a current study of 63 cases of community acquired pneumonias which required hospitalization. All 4 patients presented chronic cardiopulmonary diseases. These facts and additional seroepidemiological studies with a frequency of 53% of previous contact, show that C. pneumoniae has a nonrare etiology in Spain and could be an endemic condition.
