An infantile case of Zellweger syndrome presented with Kabuki-like phenotype.

Zellweger syndrome is a peroxisomal disorder resulting from the mutations in PEX genes generally presenting in the neonatal period with profound hypotonia seizures, inability to feed, liver cysts with hepatic dysfunction, chondrodysplasia punctata. Kabuki make-up syndrome is a multiple congenital anomalies and mental retardation syndrome with characteristic facial appearance, skeletal abnormalities, dermatoglyphic abnormalities, mental retardation and short stature. Abnormal liver functions and some atypical findings were also reported in some patients with Kabuki syndrome. In this report a case with late onset Zellweger syndrome who had some phenotypical findings which are also seen in Kabuki Syndrome will be presented. The inclusion of Zellweger syndrome into the differential diagnosis of the patients with Kabuki-like phenotype in addition to abnormal liver functions is emphasized.

Multisystem involvement in a patient due to accumulation of amylopectin-like material with diminished branching enzyme activity.

We report a 13-year-old boy with multisystem involvement secondary to accumulation of amylopectin-like material. He was born to consanguineous parents at full term without any complications and his maternal perinatal history was uneventful. His parents were cousins. He had normal growth and development except for his weight. His sister died from an unexplained cardiomyopathy at the age of 8 years. Our patient's initial symptom was severe heart failure. Since he also had a complaint of muscle weakness, electromyography was performed which showed muscle involvement. The diagnosis was suggested by tissue biopsy of skeletal muscle showing intracellular, basophilic, diastase-resistant, periodic acid-Schiff-positive inclusion bodies and was confirmed by the presence of a completed branching enzyme deficiency. Similar intracytoplasmic inclusion-like bodies were also found in liver biopsy, but very few in number compared with the skeletal muscle. The patient died from an intercurrent infection. Postmortem endomyocardial biopsy revealed the same intracytoplasmic inclusions as described above affecting almost all myocardial cells. Ultrastructural examination of liver biopsy was nondiagnostic; however, myocardium showed prominent, large, intracytoplasmic deposits. Glycogen branching enzyme gene sequence was normal, and thus classical branching enzyme deficiency was excluded. Our patient represents the first molecular study performed on a patient in whom there was multiple system involvement secondary to accumulation of amylopectin-like material. We suggest that this is an as yet undefined and different phenotype of glycogen storage disease associated with multisystemic involvement.

Urinary 24-hour copper excretion at the time of diagnosis in children with Wilson's disease.

The optimal cut-off value of 24-hour (h) urinary copper (Cu) levels to identify Wilson's disease (WD) has not been widely studied in children. In sixty-six children with confirmed WD and 88 children without WD, 24-h urinary excretion of Cu at the time of diagnosis was studied. The receiver operating characteristic (ROC) curves revealed that the optimal cut-off value of urinary Cu to identify WD was 70 mcg [area under the curve (AUC) = 0.894] with a sensitivity and specificity of 81.8% and 89.8%, respectively. When the serum ceruloplasmin level was < 20 mg/dl and the 24-h urinary excretion of Cu was >70 mcg, the sensitivity was 75.8%, and the specificity was 97.7%. After the exclusion of cholestatic patients, the ROC curves revealed that the optimal cut-off value for 24-h urinary Cu excretion was 55 mcg (AUC = 0.910) with a sensitivity and specificity of 83.3% and 90.3%, respectively. When the ceruloplasmin level was <20 mg/dl and the 24-h urinary Cu excretion was >55 mcg, the sensitivity and specificity were 77.3% and 98.4%, respectively. A 24-h urinary Cu level of >70 mcg plus a ceruloplasmin level of < 20 mg/dl in the patients, and a 24-h urinary Cu level of >55 mcg plus a ceruloplasmin level of <20 mg/dl in non-cholestatic patients exhibited the highest specificity and the highest positive and negative predictive values to identify WD in children.

Papillon-lefevre syndrome with congenital hepatic fibrosis.

Papillon Lefevre syndrome (PLS) is a rare autosomal recessive disorder, which is characterized by palmar-plantar hyperkeratosis, periodontitis, and premature loss of dentition. We report a 16 years old girl with PLS. The patient presented at 08 years of age with complaints of corn on the feet and hands, and failure to thrive. On examination, her upper primarily canines were loose, she had severe periodontitis, eruption of permanent teeth, diffuse eritematous and hyperkeratotic palms and soles that suggested the syndrome. During the follow-up, the patient was diagnosed to have congenital hepatic fibrosis (CHF) when she was 16 years old, while she was being investigated for the etiology of her splenomegaly and pancytopenia. We report a patient with PLS associated with CHF, an association that has not been previously described.

Gastric emptying time in renal transplant recipients treated with cyclosporine.

Gastric emptying time (GET) appears to be a rate-limiting factor in the absorption of cyclosporine-A (CsA) and may be responsible for intra- and interpatient variability of CsA bioavailability. Few studies have assessed gastric motility after renal transplantation. The purpose of this study was to evaluate gastric emptying of semi-solid material in stable renal transplant patients with reference to blood CsA levels. The GET of semi-solids (GET t(1/2), half emptying time) was measured in 16 transplant recipients who were taking CsA (Neoral), prednisolone and azathioprine (or mycophenolate mofetil). The GET (t(1/2)) measured by radionuclide methods, was analyzed with reference to the daily CsA doses, levels of CsA (C(0)), and serum creatinine concentrations. The mean GET (t(1/2)) was 89.1 +/- 26.4 minutes. Twelve patients exhibited delayed gastric emptying with a mean CsA level of 171.8 +/- 56 ng/mL and a mean dose of 4.1 +/- 1.1 mg/kg/d. The GET (t(1/2)) was not significantly correlated with the serum creatinine levels, the time since transplantation, or the CsA concentration. In addition, the correlation between the mean daily CsA dose and the GET (t(1/2)) was only weakly positive, (r =.33, P =.2) and therefore, statistically insignificant. In conclusion, it could not be ascertained whether a higher dose of CsA delays gastric emptying or whether patients with delayed emptying require higher doses of CsA. However, it is believed that determining the GET after transplantation helps in the adjustment of immunosuppressant doses.
