[Ulcerative colitis and pregnancy].

BACKGROUND: The evolution of ulcerative colitis in pregnancy is far from clear. While some authors state that the disease aggravates during this period, others do not share this opinion. AIM: To assess the evolution of ulcerative colitis in pregnancy. PATIENTS AND METHODS: A paired case-control design was used in which 15 women, with diagnosed ulcerative colitis at the moment of becoming pregnant, were followed for 12 months and the activity of the disease was compared with that of the 12 months preceding the pregnancy. The activity of the disease in the period preceding the pregnancy was gathered retrospectively from the patient's charts. RESULTS: The mean age of the first ulcerative colitis crisis was 24 years. It was moderate in 49% and severe in 35% of women. During pregnancy 55% of women did not have a crisis, compared with 26.7% during the period preceding pregnancy (relative risk of not having a crisis during pregnancy of 1.7). During both periods, seven women had digestive complications, whereas extra digestive complications were not observed in 60% of patients during pregnancy and 11.8% of patients during the preceding period. Perinatal results were similar to those of the general population. CONCLUSIONS: In our group of patients the evolution of ulcerative colitis was better during pregnancy, reflected by a lower number of crisis.

[Enteral nutrition in severe ulcerative colitis. Digestive tolerance and nutritional efficiency].

BACKGROUNDS AND AIMS: Total parenteral nutrition (TPN) has been traditionally used as an adjunctive therapy in severe ulcerative colitis patients. We performed a prospective study to ascertain the safety, nutritional efficiency, tolerance and costs of total enteral nutrition in this situation. METHODS: After 48 hours of intensive medical treatment, severe ulcerative colitis patients initiated enteral feeding with a polymeric formula. The formula concentration and volume were increased daily. RESULTS: 17 patients (7 women, 10 men; age 36.8 +/- 12.8 years) with a mean clinical activity score of 15.6 +/- 1.5 were included. In 14 patients (82.4%) enteral nutrition was well tolerated, attaining in 11 of them more than 80% of the caloric requirements by day 4. In 3 cases we observed vomiting and bloating. Prealbumin levels improved significantly from 11.1 +/- 3.4 mg/dl to 22.7 +/- 6.8 mg/dl (p = 0.002) at the end of enteral nutrition (11.8 +/- 4.7 days). Albumin and other nutritional parameters did not change. CONCLUSIONS: Total enteral nutrition could be considered a safe and well tolerated nutritional support in these patients. Although albumin and other nutritional parameters did not change during the study period, the increase in prealbumin levels suggests a favourable anabolic effect of total enteral nutrition.

[Hemobilia caused by ruptured hepatic artery aneurysm].

We report two patients with hemobilia caused by hepatic artery aneurism that ruptured to the biliary tract. In the first patient, the diagnosis was made during an exploratory laparotomy. In the second patient, the aneurism was diagnosed with a selective hepatic artery arteriography and embolized during the procedure. The evolution of both patients was satisfactory.

[Incidence of bronchopulmonary dysplasia].

The incidence of bronchopulmonary dysplasia (BPD) was retrospectively studied in all ventilated newborns at a neonatal intensive care unit of a university based hospital at Santiago, Chile along a 5 years period (1983-1987). BPD incidence among the whole sample of newborn infants requiring artificial ventilation was analysed according to birth weight (BW) and compared with that of newborns surviving after 28 days of life. The possible association of BPD with hyaline membrane disease (HMD), ductus arteriosus (DA) and pulmonary air leak (PAL) was studied. The total number of ventilated newborns was 200, incidence of BPD was 9.5% (19/200) and lethality for BPD was 5.2% (1/19). The incidence of BPD increased progressively with decreasing BW, reaching 37.5% in infants less than 1,000 g (p less than 0.001 chi 2). Among 28 day survivors incidence of BPD in the same BW group increased to 75% (p less than 0.05). These findings support the idea that the incidence of BPD increases with improved survival of low birth weight infants. A positive association of BPD with DA and PAL was seen with 10/19 versus 33/181 incidence for DA (p less than 0.01) and 6/19 versus 16/181 for PAL (p less than 0.01) among patients with and those without BPD respectively, but not with HMD.
