Electroretinogram B-wave amplitude in panic disorder.

Abnormal light-related behaviors have been described for patients with panic disorder (PD). The present study was undertaken to investigate the retinal light response in PD using electroretinography (ERG). The authors conducted b-wave ERG measurements with a bright light (after dark adaptation) in 28 patients with PD and 28 control subjects. There were no significant differences in the mean b-wave amplitude between the two groups, but the retinal response to light in PD patients was generally lower than in healthy subjects. A large interindividual variability was found; also noted was a significant difference in the mean b-wave amplitude between the right and left eyes in the control group. The data indicate subtle variation of retinal photosensitivity in a subgroup of patients with PD. Because dopaminergic retinal activity affects b-ERG amplitude, the authors hypothesize that the dopaminergic system is involved in the response to light in PD patients.

Pseudodiastrophic dysplasia type Burgio in a newborn.

Pseudodiastrophic dysplasia is a distinct disorder that differs from diastrophic dysplasia on the basis of elbow and proximal interphalangeal joint dislocations, platyspondyly, and scoliosis. We report on a new patient with this rare skeletal dysplasia and two previously undescribed major malformations: omphalocele and complex heart defect.

Biliary malformation with renal tubular insufficiency in two male infants: third family report.

We report two male sibs, born to non-consanguineous healthy parents, who showed arthrogryposis, cholestatic jaundice and tubular renal insufficiency. The liver biopsy of the first case showed scanty hypoplastic biliary ducts. This association, first reported by Lutz and Richner in 1973, is a distinct syndrome, characterized by intra-extrahepatic biliary hypoplasia, and described in McKusick's catalogue under the number 210550. All reported cases were males and consanguinity was found in two families. For these reasons, the possibility of an autosomal recessive or of an X-linked transmission should be considered. A similar association, in reports by Nezelof, Di Rocco, and Saraiva, without intra-extrahepatic atresia but with a cholestatic pigmentary liver disease was considered as another condition (no. 301820) by McKusick in 1992.

Treatment of congenital ptosis by maximal levator resection.

The treatment of severe congenital ptosis may include frontalis suspension or maximal levator resection. A previous study of 145 consecutive frontalis suspensions for congenital ptosis showed a fairly high recurrence rate, frequent granuloma formation, and significant brow scars. In 28 patients undergoing 32 maximal levator resections utilizing our technique, 28 patients had excellent results. Two required reoperations and two additional patients had undercorrections that did not warrant reoperation. There were no significant complications. We believe that maximal levator resection is a better surgical alternative than frontalis suspension in the treatment of severe congenital ptosis whether unilateral or bilateral. In our experience, maximal levator resection provides a better cosmetic result and the recurrence rate is probably less than with frontalis suspension.
