Alagille's syndrome or arteriohepatic dysplasia has been described in Cuba in nine patients between nine months and 12 years of age (8 males and one female). Among the clinical features we found five major abnormalities: chronic cholestasis with neonatal jaundice (9/9), peculiar facies (9/9), peripheral pulmonary artery hypoplasia associated with cardiac murmur (6/9), butter-fly-like arch defects (4/9), and posterior embryotoxon (6/7). Two children had a severe xanthomatosis. Laparoscopy showed green hepatomegaly depending on the degree of cholestasis, and only one patient had incipient signs of micronodular cirrhosis. Liver histology showed a paucity of interlobular bile ducts. Survival was of 60%. One patient survived more than 30 years. Four patients died of liver carcinoma (unique report in infants), broncho-pneumonia, acute renal failure, and sudden death respectively. Among the minor features were mental retardation (5/9), a peculiar voice (3/9), growth retardation observed in some of our patients. This is the first report on Alagille's syndrome in Latin America, because so far reports have come only from Europe and North America.

We examined the clinical and biochemical features of 27 cases with acute myoglobinuria who had been suspected of having metabolic myopathies. The systematic biochemical studies included the measurements of 13 glycolytic enzymes, mitochondrial respiratory chain enzymes, carnitine palmitoyltransferase (CPT) and 5 enzymes of fatty acid beta-oxidation. Enzyme defects were found in 9 patients using muscle biopsy specimens: phosphorylase deficiency in 3, CPT deficiency in 4 and phosphoglycerate kinase deficiency in 2. One patient was diagnosed as MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes) with the histopathological examination and clinical data. A suspicion of beta-oxidation disorder was entertained in some patients of which the activities were about 50% of control means. However, no evidence to substantiate its significance as the enzyme defects was obtained from our data. Sixteen of 17 undiagnosed cases could be divided into two groups according to precipitating factors as follows: one had exercise as the factors and the other had infection. These groups also showed some differences in clinical features. In the infection group, myoglobinuria tended to progress more rapidly and was occasionally followed by acute renal failure. And some cases had additional associated conditions such as mental retardation or epilepsy. On the other hand, the exercise group had only myopathic symptoms. The difference in these clinical features between the two groups suggested that they had the different pathogenic mechanisms respectively.

A 49-year-old female with mental retardation was admitted with suspected renal insufficiency with a raised creatinine (5.1 mg/dl), hyperkalaemia (5.6 mmol/l), and a 12-hour history of diffuse abdominal pain and persistent vomiting. On admission, she had a haematoma around the right shoulder and arm-pit, swelling of the right upper-arm, and severe limitation of movement of the right hand. These injuries were the result of trauma some 5 days previously. She was a long-term inpatient in a psychiatric clinic, with a history of autoaggressive behaviour, which had led to several fractures in the past as a result of falls. The creatinine kinase was elevated to 6680 U/l. The suspected diagnosis of acute oliguric renal failure due to rhabdomyolysis was confirmed by the presence of marked myoglobinuria (409 ng/ml). Because of the delay in diagnosis, acute renal failure developed, and the patient required haemodialysis for 20 days. Because of their many predisposing factors, psychiatric patients represent a special risk group for development of rhabdomyolysis, recognition of which is often delayed.

Psychiatry residents completing their consultation-liaison (CL) rotations are implicitly expected to recognize and consider countertransference reactions when offering clinical recommendations. Residents often lack formal guidance in this role, as there exists limited examination of clinical scenarios from a psychodynamic perspective. The authors present a historical review of the literature on countertransference with the medically ill and describe a clinical vignette illustrating the vicissitudes of liaison work. The case involves a psychotic patient with mental retardation and acute renal failure. Through refusal of care and a tumultuous clinical course, this patient elicited various countertransferential reactions from the primary care and CL teams, in turn adversely impacting treatment. The case illustrates how clinicians' failure to collaborate led to hospital administrators having to take on the liaison role. (1) A review of literature corroborates the importance of CL psychiatrists' assistance in the management of countertransference. At the same time, it is notable for a paucity of guidance in teaching these skills to psychiatry trainees. The psychiatry resident-in-training faces challenges and shortcomings in the management of countertransference. Formal training in this aspect of psychiatric consultation is lacking, as evidenced by extant publications. The authors propose future directions for research and teaching, with emphasis on clarifying the liaison component of CL psychiatry and advocating for establishment of psychodynamic psychotherapy training guidelines in the general hospital setting.

WAGR syndrome is caused by an 11p13 deletion and includes Wilms' tumor, aniridia, genitourinary anomalies and mental retardation. We encountered a case of a dysgerminoma originating in an ectopic ovary in a woman with WAGR syndrome. Our patient was a 24-year-old nulliparous woman who was diagnosed with WAGR syndrome. The patient had undergone left nephrectomy for a Wilms' tumor and postoperative chemotherapy at the age of 7 months. She also had a history of glaucoma surgery in both eyes, and was followed up at the Department of Pediatrics for diabetes mellitus, hypertension, liver dysfunction and hyperuricemia. The patient was investigated for oliguria and had elevated levels of blood urea nitrogen (45 mg/dl) and creatinine (5.4 mg/dl); she was admitted to the hospital with acute renal failure and a computed tomography scan revealed a pelvic tumor with a long axis of 10 cm that was obstructing the right ureter. Following insertion of a ureteral stent, the tumor was removed. The tumor had developed in the retroperitoneal space independent of the ovaries. The right adnexa were normal. The tumor was histopathologically diagnosed as dysgerminoma. Follicles were found in part of the tumor; it was thus hypothesized that the tumor developed from an ectopic ovary. The patient was administered etoposide after surgery, and has been recurrence-free for 4 years since treatment.
