We investigated five cases with cerebrotendinous xanthomatosis (CTX) with particular reference to biochemical and pathological pulmonary disorders. To date, few reports discuss the pathophysiology of pulmonary disorders of CTX patients. This study is the first investigation of such pulmonary disorders. All 5 patients had no pulmonary symptoms and no disturbances on radiological studies and pulm...

We measured the cholestanol, cholesterol precursor (lathosterol), and plant sterol (campesterol and sitosterol) concentrations of serum and bile in 11 patients with cerebrotendinous xanthomatosis. The mean values of serum cholestanol, lathosterol, campesterol, and sitosterol were, respectively, 8.4-, 2.5-, 2.7-, and 1.4-times higher in the patients than in normal control subjects (n = 26). Chol...

Using isotope dilution-mass spectrometry, it was shown that human bile contains significant amount of 7 alpha-hydroxy-4-cholesten-3-one, an intermediate in the major pathway for bile acid biosynthesis. In bile from 14 healthy subjects, the concentration was 0.14 +/- 0.01 micrograms/ml (mean +/- S.E.). Four bile samples collected from two patients with cerebrotendinous xanthomatosis contained co...

Cerebrotendinous xanthomatosis (CTX), also known as Van Bogaert-Scherer-Epstein disease is a rare autosomal recessive genetic disorder of the lipid metabolism. To date, there are less than 300 cases reported worldwide. We present a case of a 30 year old male who presented with mental retardation and swelling of ankles, with the a spectrum of CTX imaging findings. Imaging studies were performed ...

Cerebrotendinous xanthomatosis is a treatable rare autossomal recessive disease characterized by lipid storage secondary to a sterol 27-hydroxylase deficiency in the formation of cholic and chenodeoxycholic acids. We describe two Brazilian brothers with cognitive impairement and chronic diarrhea. One of them also presents bilateral cataracts. Neurological findings were progressive walking defic...

Recent studies have reported a widespread distribution of extended-spectrum β-lactamase (ESBL)-producing bacteria, not only in the nosocomial setting, but also in the community; some local communities in Southeast Asia have been reported to show a high prevalence of ESBL-producing bacteria. However, the details regarding the quantitative/qualitative state of ESBL-producing bacterial spread in S...
