1/1537. Variable clinical expression of Holt-Oram syndrome in three generations.

    Holt-Oram syndrome is a distinct autosomal dominant entity presenting with upper limb defects and cardiac abnormality. No correlation between the severity of the heart and the limb defects has been established. Here we report variable clinical expression of Holt-Oram syndrome in three generations. The grandfather presented with typical upper limb defects: phocomelia of arms with three digits on each hand, congenital heart defect and narrow shoulders. His son manifested cardiac conduction disturbance with no congenital heart or skeletal defect. The granddaughter showed ventricular septal defect and moderate radial deviations of both hands with no obvious hypoplasia of the extremities. Clinical data of the presented family suggests lack of penetrance with respect to skeletal and structural cardiac abnormalities in the Holt-Oram syndrome.

2/1537. Rigid spine syndrome. Case report.

    We describe a patient who had difficulty in walking since toddling stage and presented proximal upper and lower member weakness which have evolved to a progressive limitation of neck and trunk flexure, compatible with rigid spine syndrome. The serum muscle enzymes were somewhat elevated and the electromyography showed a myopatic change. The muscle biopsy demonstrated an active and chronic myopathy. The dna analysis through PCR did not display any abnormality for dystrophin gene. The dystrophin by immunofluorescence was present in all fibers, but some interruptions were found in the plasma membrane giving it the appearance of a rosary. The test for merosin was normal.

3/1537. Wellens' syndrome.

    We describe a patient with Wellens' syndrome. In view of the large area of myocardium at risk, the importance of recognizing the significance of this ECG pattern is of critical importance for the emergency physician, especially those involved in the evaluation of patients at emergency department chest pain centers. Wellens' syndrome, the criteria for diagnosis, and a discussion of its implications are presented.

4/1537. Rare dental abnormalities seen in oculo-facio-cardio-dental (OFCD) syndrome: three new cases and review of nine patients.

    Oculo-facio-cardio-dental syndrome is a very rare condition. So far, only nine cases have been documented. We report on three additional female patients representing the same entity. The clinical findings were: congenital cataract, microphthalmia/microcornea, secondary glaucoma, vision impairment, ptosis, long narrow face, high nasal bridge, broad nasal tip with separated cartilages, long philtrum, cleft palate, atrial septal defect, ventricular septal defect, and skeletal anomalies. The following dental abnormalities were found: radiculomegaly, delayed dentition, oligodontia, root dilacerations (extension), and malocclusion. For the first time, fusion of teeth and hyperdontia of permanent upper teeth were seen. In addition, structural and morphological dental changes were noted. These findings expand the clinical spectrum of the syndrome.

5/1537. (TA)8 allele in the UGT1A1 gene promoter of a Caucasian with Gilbert's syndrome.

    BACKGROUND AND OBJECTIVE: Gilbert's syndrome, a chronic non-hemolytic unconjugated hyperbilirubinemia, is caused by a reduction in the activity of hepatic bilirubin UDP-glucuronosyltransferase (UGT1A1). This reduction has been shown to be due to a polymorphism in the promoter region of the UGT1A1 gene. The presence of seven thymine adenine (TA) repeats reduces the efficiency of transcription of the UGT1A1 gene. To elucidate the genetic background of a patient affected by Gilbert's syndrome, we collected blood samples from family members for the analysis of the A(TA)nTAA motif in the promoter region of the UGT1A1 gene. DESIGN AND methods: Analysis of the A(TA)nTAA motif in the promoter region of the UGT1A1 gene was performed by PCR. Estimation of UGT1A1 promoter containing the variable (TA) repeats was performed by using a luciferase reporter system. RESULTS: Three different genotypes were identified due to the presence of (TA)6, (TA)7 and (TA)8 repeats. The production of luciferase decreases in inverse relation to the number of repeats. INTERPRETATION AND CONCLUSIONS: The (TA)7 polymorphism, associated with Gilbert syndrome, is the only allele found up to now in white populations, while two other variants (TA)5 and (TA)8 have been identified in black populations. We describe here the first case of a subject affected by Gilbert's syndrome who is heterozygous for the (TA)8 allele in the promoter region of the UGT1A1 gene. This polymorphism, as well as the (TA)7 one, is associated with an increased level of bilirubin and a significant reduction of transcription activity of the UGT1A1 gene.

6/1537. Splenic syndrome in sickle cell trait: four case presentations and a review of the literature.

    Four cases of splenic infarction/sequestration in sickle cell trait (SCT) patients are presented. All four patients were undergoing moderate exercise at elevations ranging from 5,500 to 12,000 feet. The patients include two African-American males, a Hispanic male, and a white female. All four presented with the acute onset of mid epigastric then left upper-quadrant pain, nausea, vomiting, and respiratory splinting. A review of the literature indicates that splenic infarction with SCT is not uncommon; however, not surprisingly, it is often initially misdiagnosed. This is the first report in the literature of a female with SCT incurring a splenic syndrome with exposure to terrestrial altitude. Although SCT is not a contraindication for moderate- or high-altitude activities, military physicians need to consider the diagnosis of splenic infarction early in any patient regardless of race or sex who presents with left upper-quadrant pain at altitudes above 5,000 feet. Prompt evacuation to sea level may hasten recovery and spare further splenic trauma. Although SCT should be considered a relatively benign entity, the literature also suggests a higher than average risk of sudden death in military recruits with SCT from exertional heat illness and rhabdomyolysis.

7/1537. An unusual case of hypoglossia-hypodactyly syndrome.

    Hypoglossia-hypodactyly syndrome is seen very rarely and its appearance is sporadic. Different degrees of tongue hypoplasia and transverse deficiencies in the upper extremities are seen. In the patient presented there was a sulcuslike deformity at the midline of the lower lip, and the continuity of the orbicularis oris muscle was disturbed at this location, in addition to the classic findings of hypoglossia-hypodactyly syndrome. A description of this variant and its treatment are described.

8/1537. hepatic encephalopathy--a physostigmine-reactive central anticholinergic syndrome?

    This report describes an association between hepatic encephalopathy and central anticholinergic syndrome (CAS). A 60-year-old anaemic woman was admitted unconscious and with a delayed reaction to pain but with no focal neurological deficits. She had signs of portal hypertension and a history of non-alcoholic liver cirrhosis grade child B. Suspecting upper gastro-intestinal bleeding, she was intubated for gastro-duodenoscopy and a fibrin-covered ulcer was revealed. Raised intra-abdominal pressure resulting from ascites caused cardiopulmonary failure, which required mechanical ventilation for 24 h, but extubation was possible after drainage of the ascites and blood volume replacement therapy. However, her neurological state remained unchanged despite normal blood ammonia concentration and no sedation. CAS was considered and physostigmine injected with immediate effect. The patient opened her eyes immediately and was fully orientated to personal and medical history. We suggest that hepatic encephalopathy may trigger CAS, although the significance of physostigmine in the treatment of hepatic encephalopathy remains to be addressed by controlled investigations.

9/1537. Stress-induced SAPHO syndrome.

    We describe the case of a woman with the classic combination of features of synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome, including pustulosis palmo-plantaris and anterior chest wall involvement. The varying symptomology, etiology and pathogenesis of this syndrome and the contribution of stress are discussed. The authors ascribe the dearth of reported cases to lack of awareness and recognition of SAPHO, and not to the real incidence of the syndrome.

10/1537. posterior leukoencephalopathy syndrome may not be reversible.

    The association of an acute reversible encephalopathy with transient occipital lobe abnormalities on imaging studies is well known. This condition has been called reversible posterior leukoencephalopathy syndrome. The clinical presentation usually includes seizures, headache, altered mental status, and blindness, often associated with hypertension and immunosuppressants. The authors discuss a two-year-old male with down syndrome who presented 2 months after allogeneic bone marrow transplantation with severe oculogyric crisis, without other complaints. The patient was being treated for hypertension and was receiving cyclosporine for prophylaxis of graft-vs-host disease. A computed tomography scan of the head revealed marked bilateral lucencies mainly involving the white matter of the occipital lobes, with a few foci of punctate hemorrhage. The condition improved when cyclosporine was discontinued, but an area of leukomalacia was identified on follow-up magnetic resonance imaging. To the authors' knowledge, oculogyric crisis as a presentation of reversible posterior leukoencephalopathy has not been previously described. Recognizing this association is important, because patients receiving cyclosporine are often receiving other medications that can potentially cause dystonic eye movements, possibly leading to a delay in diagnosis and treatment, which can result in an irreversible neurologic deficit.
