The first case of successful bone marrow transplantation (BMT) in a patient with I-cell disease is reported. A 8-month-old girl with I-cell disease (N-acetylglucosaminylphosphotransferase deficiency) has had successful reconstitution with bone marrow from her HLA-MLC-matched brother who has heterozygous level of the transferase activity. The following biochemical and clinical improvements have occurred: the transferase in peripheral lymphocytes increased to donor's level, and lymphocytic alpha-neuraminidase, beta-galactosidase and alpha-mannosidase increased to normal levels. Plasma acid hydrolase activities, which had been 10 to 60 times higher in the patient than normal control levels, have slowly but steadily decreased from one month after the graft. Such decreases were observed in the activities of alpha-mannosidase, N-acetyl-beta-glucosaminidase, alpha-fucosidase, arylsulfatase A and acidic beta-galactosidase. There was also a marked decrease of vacuolated peripheral lymphocyte after the BMT. Three-months after the engraftment, hepatomegaly gradually decreased in size, corneal clouding has not progressed, and tight skin seems to have improved.

A long-surviving clinical case of suspected Morquio's syndrome is described. The locomotorium (vertebral dwarfism, hyphoscoliosis, but no hypoplasia of the odontoid process of the epistropheus, platyspondylia), cardiopulmonary (aortic insufficiency, arterial calcification, varices) visual (opaque lens on right eye, sclerosis of the lenticular lamellae but no corneal opacity on left eye) acoustic (deafness) and gastroenteric systems (hepatomegaly) are analysed. No pathological granulations were noted in the leukocytes. The plasmatic lysosome enzymes were normal and alpha-fucosidase subnormal. Abnormal keratan sulphate secretion was noted in the daily urine. All this would explain the patient's long survival.

A 17-year-old Japanese boy was found to have ataxia, generalized angiokeratomas, skeletal deformities, visual impairment, and macular cherry-red spots, without hepatomegaly, splenomegaly, or renal failure. Laboratory examination disclosed a deficiency of beta-galactosidase as well as of neuraminidase activity in the leukocytes and fibroblasts, while alpha-galactosidase and alpha-L-fucosidase activities were normal. On electron microscopic examination, numerous cytoplasmic vacuoles containing flocculated material were found in the vascular endothelial cells, histiocytes, perineurial cells, and Schwann's cells.

Fucosidosis is a rare, autosomal recessive lysosomal storage disorder caused by a severe deficiency of alpha-L-fucosidase. Here we present a 27-month-old male who was referred to us for evaluation of developmental delay, which was first detected at age six months. His past medical history was also remarkable for recurrent pulmonary infections and myoclonic seiures. His family history revealed that he was the first living child from a consanguineous marriage. He had a younger sister who died at five months of age from pneumonia who had facial resemblance to the proband, developmental delay and a congenital heart defect. Physical examination revealed length: 81 cm (25-50p), weight: 10.2 kg (25-50p), and head circumference: 49 cm (50-75p). He had a coarse face, hepatomegaly and generalized spasticity. His initial laboratory examination revealed negative urine screening column chromatography for mucopolysaccharidosis. His X-ray findings were consistent with mild form of dysostosis multiplex. Based on clinical and laboratory features, fucosidosis was suspected. Fucosidase enzyme activity was zero. In addition to fucosidosis, thyroid function tests indicated primary hypothyroidism. This is, to the best of our knowledge, the fourth case of fucosidosis diagnosed in Turkey.
