[Amoxicillin-clavulanic acid induced hepatotoxicity with progression to cirrhosis].

Amoxicillin-clavulanic acid is a commonly used antibiotic in clinical practice. It is usually prescribed on an empirical basis and several cases of hepatotoxicity with cholestasis have been described. We report the case of a 42-year-old man who developed an acute hepatocellular lesion with progression to cirrhosis. The patient received amoxicillin-clavulanic acid twice with an interval of four months. Other causes of hepatic failure were excluded. Although amoxicillin-clavulanic acid-induced hepatotoxicity has been widely documented, there are no other reports describing its progression to cirrhosis in an adult.

[Papillary tumor of the pancreas diagnosed by fine-needle aspiration].

We report the case of a 48 year-old woman with an epigastric palpable mass identified by abdominal echography and computed tomography as a solid pancreatic tumor. A cytology taken by fine needle aspiration guided by computed tomography was diagnostic of papillary pancreatic tumor, which was confirmed by surgical resection. We emphasize the low frequency and good prognosis of this type of tumor after surgical resection, and the utility of image techniques and fine needle aspiration to obtain a preoperative diagnosis.

[Thyroid dysfunction in patients with chronic hepatitis C pre and post treatment with interferon].

OBJECTIVE: The aim of this study was to evaluate the thyroid function and the dysfunction after interferon therapy in patients with chronic hepatitis C. MATERIAL AND METHODS: Between 1988 and 1994, 119 patients with chronic hepatitis C treated with interferon were reviewed 92 patients received interferon alfa for six or twelve months. 27 patients were treated with interferon beta for six months. Before, during and after interferon therapy, free thyroxine, thyroid-stimulating hormone, antimicrosomal antibodies and antithyroglobulin antibodies were measured in 51 patients. None of the patients had abnormal thyroid function or autoimmune disease before treatment. RESULTS: Among the interferon-treated patients, 6% developed biochemical evidence of thyroid dysfunction during or after therapy. Most cases had hypothyroidism. Thyroid dysfunction was statistically more frequent in the female sex, older patients and in patients who received greater total dose of interferon. In one patient the titters of antimicrosomal thyroid antibodies increased from 1/10 to 1/40 and another patient was positive in a dilution of 1/80 by the time of onset of thyroid disease. Thyroid disease (hypothyroidism) developed in (3.5%) of untreated patients with chronic hepatitis C. CONCLUSIONS: Interferon therapy can development autoimmune thyroid fenomena. Thyroid dysfunction and the presence of antithyroid antibodies before therapy can be a contraindication to the use of interferon in these patients. It is important that patients undergoing interferon therapy be tested for antithyroid antibodies and thyroid function before treatment and be monitored during the course of therapy. Also, it is important to evaluate the factors related with the development of thyroid dysfunction (age, sex, interferon dose...).

[Intrahepatic cholestasis of pregnancy. Maternofetal implications].

OBJECTIVE: To analyze a group of pregnancies complicated by intrahepatic cholestasis in order to favour an early recognition and to decrease maternal and fetal morbid-mortality. PATIENTS AND METHODS: Retrospective study of 46 pregnancies with intrahepatic gravidic cholestasis between 1990-94. We review the most relevant epidemiologic, clinical and biological features and the obstetric and perinatal results. The study group was compared with 1652 non complicated pregnancies (control group) from the same period of time. The statistic evaluation was made with t Student and chi 2. RESULTS: The incidence was 0.18% (mean age of 27.8 +/- 6.7 years) similar to the control group, and a greater rate of primiparity (p < 0.05) and twin pregnancies (p < 0.001). The most frequent symptom was pruritus, followed by choluria (23.9%) and signs of cutaneous scratching (17.3%). Only 5 patients (10.8%) had jaundice. The GPT was greater than 100 U/1 in 29 cases (63.1%) and the GOT in 17 (37%). In 25 pregnancies (54.3%) the alkaline phosphatase exceeded 600 U/L and 28 (60.8%) had bilirubin normal values. Urinary tract infections (26%) and preterm labor (17.3%) were significantly more frequent (p < 0.001) in patients with intrahepatic cholestasis of pregnancy, as well as induced labor rate and cesarean section percentages (p < 0.001). The neonatal prognosis was significantly worse, with 10 preterm babies, 6 with 5 minutes Apgar score lower than 7, and 3 perinatal deaths. All the patients recovered their normal status after delivery. CONCLUSIONS: In intrahepatic gravidic cholestasis moderate cytolysis, infrequent jaundice and cholestasis can be important. The pregnancies should be considered of high risk, and should be managed aggressively as soon as fetal maturity allows it.

[Involvement of the facial nerve in tumors of the neck and face. Report of 17 cases].

Seventh nerve involvement for tumors of the neck of the face is an event not too much infrequent. The paralysis can present due to direct propagation or for not close vicinity. Seventeen (17) patients with facial palsies in association with neoplasties seen in a four years term (1989 - 1992) are contemplated. This figure represents a 6.6 percent of the whole number studied (N. = 270). The paper deals with clinical, etio-pathogenic features and especially with the so-called "alarm signals".

[Esophageal stenosis due to a dissecting intramural hematoma following the endoscopic sclerotherapy of esophageal varices].

The dissecting intramural hematoma of the esophagus (DEH) is a rare complication of endoscopic variceal sclerotherapy (EVS). We present a 37 years male with Laennec's cirrhosis who developed a submucosal hematoma with complete obstruction of the esophagus 24 h. after the second session of EVS diagnosed by endoscopy. After conservative treatment the patient recovered well with complete resolution of the lesion. The review of the literature shows no correlation between DEH and type or volume of sclerosant, site of injection or previous number of sessions. Unknown in children. Most of these patients had abnormal hemostasis. We have performed EVS in 227 patients (879 sessions), with only a case of DEH (rate 0.13%). In this case the bad tolerance and movements during of EVS were very important.
