3-methylcrotonyl-CoA carboxylase deficiency is an autosomal recessive disorder characterized by a defect in leucine catabolism. We report the case of an 80-day-old patient with 3-methylcrotonyl-CoA carboxylase deficiency who had elevated levels of 3-hydroxyisovalerylcarnitine (45.56 micromol/L; reference range, <0.65 micromol/L), which was detected using tandem mass spectrometry during newborn screening, and elevated levels of 3-hydroxyisovaleric acid (375.75 mmol/mol Cr) and 3-methylcrotonylglycine (502.36 mmol/mol Cr ), which were detected in urine organic acid analysis. We performed direct sequence analysis of all the exons of the MCCC1 and MCCC2 genes. No mutations were detected in the direct sequence analysis of MCCC1. However sequencing of the MCCC2 gene revealed a mutation caused by a heterozygous G to C transversion [c.313G>C (p.Gly105Arg)] at nucleotide position 313 and a mutation caused by a heterozygous A to T transversion [c.1252A>T (p.lle418Phe)] at nucleotide position 1252. Identification of these 2 novel MCCC2 gene mutations in our patient suggested that analysis of the MCCC1 and MCCC2 genes might prove useful in the diagnosis of 3-methylcrotonyl-CoA carboxylase deficiency.

OBJECTIVES: Ovarian hormones have been shown to regulate body weight, intra-abdominal fat accumulation and plasma level of cytokines. The aim of this study was to investigate the effect of estrogen replacement therapy on visceral adipose tissue, plasma level of apelin, lipid profiles, and glucose in ovariectomized (OVX) rats. METHODS: Thirty female Wistar rats were divided into OVX (n = 20) and sham (n = 10) groups. OVX rats were subdivided into estrogen replacement therapy (OVX+est; n = 10) receiving 17 β-estradiol valerates (30 µg/kg, s.c., 5 day/week, for eight weeks), and vehicle control group receiving sesame oil same as experiment group (OVX+ses oil; n = 10). After the treatments, all groups were sacrificed and blood samples were collected, visceral fats were taken from the abdominal cavity and weighed immediately. Apelin were measured using enzyme-linked immunosorbent assay kits. Lipid profiles and glucose were measured using the enzymatic colorimetric method. Data were analyzed with one-way analysis of variance and (P < 0.05) determined as the statistical significance level. RESULTS: After eight weeks, body weight, body mass index (BMI), visceral fat, apelin and lipid profiles (P < 0.01) were increased significantly in OVX rats compared to sham group. Treatment with estrogen leads to significant reduction in body weight and BMI (P < 0.05), there was no significant change in serum apelin level in OVX+est rats compared to OVX+ses. CONCLUSIONS: These results suggest that estradiol replacement therapy successfully attenuated some of the metabolic syndrome components, and apelin does not probably stand as a mediator of these physiological functions.

Valproic acid intoxication is a fairly common clinical problem that can result in serious complications. Traditionally the treatment of valproic acid overdose has been limited to supportive measures, but high blood levels may require extracorporeal removal, and publications on this experience are scarce. This case demonstrated continuous veno-venous hemodiafiltration successfully used in patient with severe valproic acid overdose who was hemodynamically unstable.

Polyhydroxyalkanoates (PHA) is a family of microbially synthesized polyesters consisting of various 3-hydroxyalkanoate monomers. Aeromonas hydrophila 4AK4 could be able to synthesize PHA copolymer consisting of 3-hydroxybutyrate (3-HB) and 3-hydroxyhexanoate (3-HHx). No data has been reported about the ability to synthesize the PHA with other monomers in A. hydrophila. In this study, propionic acid, valeric acid, heptanoic acid, nonanoic acid and undecanoic acid were used together with gluconate to find out whether A. hydrophila 4AK4 could synthesize the PHA consisting of odd carbon atom number monomers. The result showed that A. hydrophila 4AK4 could not growth when supplied with propionic acid, valeric acid, heptanoic acid and nonanoic acid and only undecanoic acid could be used to synthesize PHA. Wild type and recombinant A. hydrophila 4AK4 harboring phaA (beta-ketothiolase) and phaB (acetoacetyl-CoA reductase) were cultivated with undecanoic acid and glucose or undecanoic acid and gluconate served as carbon sources. PHA consisting of 3-HB and 3-hydroxyvalerate (3-HV) could be produced by both wild type and recombinant A. hydrophila 4AK4 and the latter could produce PHA with more 3-HB monomer. When the ratio of glucose or gluconate to undecanoic acid was 1:1, the cell dry weight (CDW) of A. hydrophila 4AK4 reached 1.14 g/L and PHA content was 60% of the CDW after cultivation for 24 h. When lauric acid and undecanoic acid were served as co-substrate, A. hydrophila 4AK4 could produce copolyester consisting of 3-HB, 3-HV and 3-HHx. Along with the increase of undecanoic acid proportion in the mixed carbon source, the 3-HV content of copolymer was increased while the 3-HB and 3-HHx content were decreased. In all cases, the CDW decreased along with the increase of undecanoic acid concentration, which indicated that undecanoic acid was not very good for A. hydrophila 4AK4 growth.

PURPOSE: To evaluate the efficacy of vigabatrin and valproic acid add-on therapy in the treatment of uncontrolled partial-onset seizures through randomized active controlled parallel-group trial. METHODS: Criteria for entry included a requirement for three or more partial seizures per month despite the blood level of carbamazepine was within therapeutic range. During the 56-day baseline period, patients had at least 6 partial onset seizures. Vigabatrin or valproic acid were administered as the second drug in a randomized fashion. RESULTS: Forty one patients completed the trial(21 for vigabatrin, 20 for valproic acid). There is no statistically significant difference in age, age at onset, baseline seizure frequency, dose of carbamazepine, and serum level of carbamazepine between two groups. Two patients of vigabatrin-treated group and three patients of valproic acid treated group were dropped out because of side effects. The mean vigabatrin and valproic acid does were 2809 and 1490 mg, respectively. The percentage of patients achieving at least a 50% reduction in seizure frequency at the end of 8-week of add-on trial was 62% among vigabatrin-treated patients and was 50% for patients who received valproic acid(not statistically different). There was no significant difference in seizure reduction, percent seizure reduction, and truncated percent seizure reduction between two groups. The side effects were mild and transient neurotoxic symptoms in the patients who completed the trial(5 patients for vigabatrin, 10 patients for valproic acid). CONCLUSIONS: This trial indicates that vigabatrin and valproic acid are safe and effective in the treatment of intractable partial-onset seizures. The efficacy of vigabatrin as a new add-on antiepileptic drug is comparable to the previous valproic acid carbamazepine combination in the sense of seizure reduction and maybe even superior to that in the consideration of side effects
