Complex facio-audio-symphalangism syndrome. an autosomal recessive type?: This report describes a new case of facio-audio-symphalangism syndrome in a 32-year-old female patient from a consanguineous family. She had a severely mentally retarded and anophthalmic sister. These associations might be coincidental or demonstrate genetic heterogeneity in this syndrome We note the diagnostic features of the case, discuss the novel association with consanguinity and highlight the possible heterogeneity of the facio-audio-symphalangism syndrome. 相似文献

Sixteen cases of Guillain-Barré syndrome occurred in the third week of a diarrhoea epidemic caused by water pollution in EL-Sult, Jordan. Of 30 000 people exposed to polluted water, 5000 developed diarrhoea, 74 typhoid, and 30 infectious hepatitis. Thirteen of the 16 patients with Guillain-Barré syndrome had been mildly affected by diarrhoea 8-24 days before the onset of peripheral neuropathy. Paralysis progressed rapidly, reaching a peak in one to five days, and recovery began three to seven days after the start of the most severe symptoms. All but four patients had recovered completely after one year. Rapid progress of paralysis and a delayed interval between maximum weakness and start of recovery were both associated with poor prognosis. 相似文献

Guillain-Barré syndrome is the most common polyneuropathy causing major disability and respiratory failure. Respiratory complications are the main cause of death. Improved respiratory care and new treatment strategies such as plasmaphoresis and immunoglobulin have been shown to improve outcome. We studied the course and outcome of 37 patients with Guillain-Barré syndrome who were admitted to a rehabilitation and respiratory care facility over a 10-year period. There were 21 males and 16 females with a mean age of 62+/-3 years. Fourteen patients developed respiratory failure requiring endotracheal intubation and mechanical ventilation. The mean duration of mechanical ventilation was 38+/-10 days. All patients were successfully liberated from the ventilator. However, 83 percent of the patients were moderately to severely disabled at the time of discharge. Thirteen out of 37 (35 percent) developed long-term disability. None of the patients died over the period of follow-up. These results indicate that early recognition and treatment of respiratory complications in Guillain-Barré syndrome could reduce the morbidity and mortality of this condition. 相似文献

Summary The incidence of Edwards' syndrome was found to be 1 per 4857 newborn children of 34000 consecutively newborn children in two Danish counties. Six of the 7 cases were born during the months of February through April.The incidence was high compared with the expected incidence of Edwards' syndrome of approximately 1 per 10000. This might be due to clustering in the area studied during the period 1967 to 1973.The finding of variations in incidence of children with Edwards' syndrome in different parts of the world, as well as the finding of seasonal variation in birth of such children, indicates that some of the etiological factors of nondisjunction of chromosome 18 are of an environmental nature. 相似文献

The association between Campylobacter jejuni infection and Guillain-Barré syndrome was investigated serologically in a retrospective study of 56 patients admitted to this hospital over four years. Evidence of preceding C jejuni infection was found in 21 (38%) of these patients, indicating that C jejuni was the most common single identifiable pathogen precipitating the disease. Among those patients who had presented with preceding diarrhoea the serum antibody response was similar to that in uncomplicated C jejuni enteritis. Patients with serological evidence of preceding C jejuni infection manifested a significantly more severe form of the disease. In cerebrospinal fluid the predominant specific antibody class was IgG, and this was closely related to the serum titres of specific IgG. IgA and IgM specific antibodies were found only in the cerebrospinal fluid of patients with recent C jejuni infection. These findings support the possibility that humoral immune factors are responsible for the neural damage and demyelination seen in Guillain-Barré syndrome. 相似文献

Synthesis of glycosaminoglycans (GAGS) by fibroblasts derived from seven patients with Down's syndrome, five patients with Edwards' syndrome, and two patients with Patau's syndrome were studied in cell culture. The aneuploid strains were compared with diploid fibroblasts from age-matched controls. In terms of hyaluronic acid and sulfated GAG synthesis, the amount of synthesized hyaluronic acid was not significantly different between postnatal aneuploid strains and controls. 相似文献

Down syndrome is the most common chromosomal abnormality. A simultaneous occurrence with Marfan syndrome is extremely rare. We present a case of a 28-year-old female with Down syndrome and a mutation in the fibrillin-1 gene. The patient showed strikingly few manifestations of Marfan syndrome. Although variable expression is known to be present in Marfan syndrome, phenotypic expression of Marfan syndrome in our patient might be masked by the co-occurrence of Down syndrome.

T cell subpopulations (Tμ and Tγ cells) were examined in the peripheral blood from fourteen patients with mycosis fungoides and Sézary syndrome. One patient with Sézary syndrome having low lymphocyte count had higher proportions of Tγ cells when compared to controls while the other with high lymphocyte count (75% Sézary cells) lacked Tγ cells and had normal proportions of Tμ cells. T cells from a third patient with Sézary syndrome having high lymphocyte count (95% Sézary cells) lacked almost completely both Tμ and Tγ cells. Three of eleven patients with mycosis fungoides had a high proportion of Tγ cells and one had a high proportion of Tμ cells. Study of T cells in the peripheral blood, lymph nodes, and bone marrow from two patients with mycosis fungoides demonstrated that the quantitative abnormality of tμ and Tγ cells is shared by the peripheral blood and bone marrow and not by the lymph nodes. Heterogeneity of T cells subsets in mycosis fungoides appears to be in non-malignant T cells. However, in Sézary syndrome malignant Sézary T cells demonstrate heterogeneity with regard to receptors for IgM (Tμ) and IgG (Tγ). 相似文献

Investigations of the association between autism and the fragile-X syndrome have yielded conflicting results with some studies indicating a strong correlation and others indicating no relation between the disorders. In this paper, we review the relevant research on this controversy and discuss the conceptual and methodological problems involved in such an inquiry. We conclude that autism and fragile X are associated and that this relation will prove fruitful in understanding the role of the X chromosome in a variety of behavior disorders and in unraveling various theoretical accounts on the etiology of autism. 相似文献

The behavioural phenotype of women with Turner syndrome (X-monosomy, 45,X) is poorly understood, but includes reports of some social development anomalies. With this in mind, accuracy of direction of gaze detection was investigated in women with Turner syndrome. Two simple experimental tasks were used to test the prediction that the ability to ascertain gaze direction from face photographs showing small lateral angular gaze deviations would be impaired in this syndrome, compared with a control population of men and women. The prediction was confirmed and was found to affect both the detection of egocentric gaze from the eyes (''is the face looking at me?'') and the detection of allocentric gaze, where the eyes in a photographed face inspected one of a number of locations of attention (''where is she looking?''). We suggest that dosage-sensitive X-linked genes contribute to the development of gaze-monitoring abilities. 相似文献

The author describes the course and treatment of a severe acute illness that began with cranial nerve palsies and ataxia and progressed rapidly to generalized weakness with respiratory embarrassment. There was no sensory loss or elevation of the protein level in the cerebrospinal fluid. The Miller Fisher variant of Guillain-Barré syndrome was diagnosed. At the height of the illness, a period lasting about 2 weeks, the author was almost completely paralysed, retaining only a little motion in some fingers and one foot; she was able to breathe on her own but required suctioning through a tracheostomy, and her eyes had to be taped shut because of her facial paralysis. She remained mentally alert throughout. Proper care of such a helpless patient demands not only excellent technical performance of many nursing procedures but a sensitivity to the patient as a person. The author describes the many shortcomings of the care she received and the value of physiotherapy in her rehabilitation and makes a number of specific recommendations for the care of critically ill conscious patients. 相似文献
