On a historical note: the legacy of Thomas Hodgkin.

Physicians in the practice of insurance medicine are exposed to an unbelievable spectrum of pathology. This series of short biographies is intended to give the reader a quick overview of the history of diseases encountered in our everyday practice and to see "the face behind the name." In the first article of this series, I wish to pay homage to one of the "great men of Guy's," Dr. Thomas Hodgkin.

Ocular motility changes after subtenon carboplatin chemotherapy for retinoblastoma.

BACKGROUND: Focal subtenon carboplatin injections have recently been used as a presumably toxicity-free adjunct to systemic chemotherapy for intraocular retinoblastoma. OBJECTIVE: To report our clinical experience with abnormal ocular motility in patients treated with subtenon carboplatin chemotherapy. METHODS: We noted abnormal ocular motility in 10 consecutive patients with retinoblastoma who had received subtenon carboplatin. During ocular manipulation under general anesthesia, we assessed their eyes by forced duction testing, comparing ocular motility after tumor control with ocular motility at diagnosis. Eyes subsequently enucleated because of treatment failure (n = 4) were examined histologically. RESULTS: Limitation of ocular motility was detected in all 12 eyes of 10 patients treated for intraocular retinoblastoma with 1 to 6 injections of subtenon carboplatin as part of multimodality therapy. Histopathological examination revealed many lipophages in the periorbital fat surrounding the optic nerve in 1 eye, indicative of phagocytosis of previously existing fat cells and suggesting prior fat necrosis. The enucleations were technically difficult and hazardous for globe rupture because of extensive orbital soft tissue adhesions. CONCLUSIONS: Subtenon carboplatin chemotherapy is associated with significant fibrosis of orbital soft tissues, leading to mechanical restriction of eye movements and making subsequent enucleation difficult. Subtenon carboplatin is not free of toxicity, and its use is best restricted to specific indications.

Centronuclear myopathy and cardiomyopathy requiring heart transplant.

Centronuclear myopathy has been extremely rarely associated with cardiomyopathy, which can lead to heart failure and premature death. We report the case of a 3.5-year-old girl with early-onset dilated cardiomyopathy, biventricular hypertrophy and histologic features suggestive of centronuclear myopathy. After unsuccessful medical treatment for heart failure, she underwent cardiac transplantation at the age of 4.5 years. Results of a skeletal muscle biopsy showed increased central nuclei and perinuclear vacuolations with aggregates of mitochondria. Examination of the heart at the time of transplantation confirmed a diagnosis of dilated cardiomyopathy. Histologic results revealed hypertrophic myocardiocytes, focal areas of infarction and endocardial fibroelastosis, most prominently in the left ventricle. Although cardiomyopathy is commonly associated with other childhood myopathies, to our knowledge, this is the youngest patient reported with centronuclear myopathy presenting with heart failure caused by cardiomyopathy, and the first patient to successfully undergo cardiac transplantation. One year after the heart transplant, there were no signs of rejection. We recommend detailed cardiac assessment with regular follow-up for children with histologic features consistent with centronuclear myopathy.

Characteristics of prolonged afterdischarges in children with malformations of cortical development.

We investigated aberrant cortical excitability in malformations of cortical development From subdural electrodes, we recorded afterdischarges lasting > or = 6 seconds in 12 of 13 patients with malformations of cortical development and 6 of 10 pediatric patients with nonmalformations of cortical development and reviewed amperage thresholds, distribution of afterdischarges, and motor responses. In patients with malformation of cortical development, motor response thresholds were high; afterdischarge and motor response thresholds, which essentially overlapped, inversely correlated with age (P < .01); afterdischarge thresholds declined with age; and 8 patients showed afterdischarges in remote sites. In nonmalformation of cortical development, afterdischarge thresholds did not significantly correlate with age; motor response thresholds tended to decline with age; and 2 patients had remote afterdischarges. Adolescent patients with malformations of cortical development had lower afterdischarge thresholds than adolescents with nonmalformation of cortical development (P < .05). From their high afterdischarge (and motor response) thresholds, we concluded that preadolescent patients with malformation of cortical development have less excitable, immature cortices, whereas adolescent patients with malformation of cortical development with low afterdischarge thresholds have hyperexcitable cortices. Remote afterdischarges over focal dysplastic cortex suggest aberrant cortical excitability and neural circuits.

Disorders of cortical formation: radiologic-pathologic correlation.

The advent of newer imaging techniques, such as high-resolution MR imaging and surface reconstructions of three-dimensional data sets, has led to a greater in vivo understanding of cortical malformations of the brain. Disorders of cortical formation are illustrated with routine imaging, surface reconstruction, and pathogenic specimens.
