Kabuki make-up syndrome associated with West syndrome

A Japanese boy with Kabuki make-up syndrome associated with West syndrome is reported. He developed periodic tonic spasms at 6 months of age while his electro-encephalogram also revealed hypsarrhythmia. Although only a few previously reported cases of Kabuki make-up syndrome have been associated with epilepsy, it is likely that epileptic seizures are another primary feature of Kabuki make-up syndrome.     

Comparison between famciclovir and valacyclovir for acute pain in adult Japanese immunocompetent patients with herpes zoster

Famciclovir is a guanine analog antiviral drug used commonly for herpes zoster. Efficacy of famciclovir treatment has been reported to be comparable to valacyclovir treatment. Both of these medications reduce the time to complete cessation of zoster‐associated pain including post‐herpetic neuralgia, as compared to acyclovir. We conducted a multicenter, randomized, open clinical trial in order to evaluate the extent of pain relief afforded by these two antiviral drugs during the acute disease phase of herpes zoster. The study group comprised 86 immunocompetent adult patients suffering from herpes zoster, who were treated with either famciclovir or valacyclovir for 7 days. Of these, 55 patients enrolled in this study within 72 h of the onset of the rash and 31 patients after 72 h of the onset. There was a significant reduction in acute herpes zoster pain with famciclovir on day 7 and at 2–3 weeks in both of these patient groups, while with valacyclovir, there was not significant reduction in pain on day 7. Of patients aged 50 years or older, there was a significantly earlier reduction in pain with famciclovir than with valacyclovir. In addition, a significant reduction in the number of patients with pain was observed as early as days 3–4 with famciclovir treatment as compared with valacyclovir treatment. We conclude that famciclovir was superior to valacyclovir in the relief of acute pain of herpes zoster. Accordingly, famciclovir is recommended for herpes zoster patients with moderate symptoms and a visual analog scale score of under 50 mm.     

Alpha-delta sleep in a case with non-24 h sleep-wake syndrome: Quantitative electroencephalogram analysis of alpha and delta band waves

Abstract  Four all-night polysomnograms of a 39-year-old male patient with non-24 h sleep-wake syndrome were recorded. We analysed electroencephalograms (EEG) with the power spectrum method and the wave pattern recognition analysis of Fujimori. The EEC of the rest waking condition showed normal patterns. High-voltage diffuse alpha band waves were observed in sleep stages 2, 3 and 4. The integrated area of the alpha band waves in the analysis epochs showed a strong positive correlation to the delta hand components in the power spectrum of the same epoch during sleep (correlation coefficients r = 0.762–0.815). Alpha hand waves during sleep were clearly different from the alpha waves in the rest waking condition, with respect to slower peak frequency and the frontal dominant voltage distribution.

Functional and phenotypical activation of leucocytes in inflamed human colonic mucosa

Infiltrating leucocytes are activated to generate reactive oxygen species or to produce several molecules in inflamed colonic mucosa. To clarify the phenotypical and functional properties of activating cells in colitic mucosa, 23 patients with ulcerative colitis and 13 controls were studied using a combined method for determining in situ nitroblue tetrazolium reducing activity and immunohisto-chemical characterization. Antibodies 25F9 (anti-macrophage), EG2 (anti-eosinophil cationic protein), MAC387 (anti-calprotectin, expressed by activated myeloid-histiocytes lineage), and MAC-1 (anti-CD11b) were used. The proportion of EG2, calprotectin, and CD11b-positive cells were significantly increased in inflamed mucosa. The proportion of EG2, calprotectin, and CD11b-positive cells significantly correlated with the histological degree of inflammation. Proportion of EG2-positive cells but not calprotectin nor CD11b-positive cells was significantly correlated with nitroblue tetrazolium reducing activity. Aggregated cells reducing nitroblue tetrazolium seen in severely inflamed mucosa were found to be EG2 positive. Most of the calprotectin-positive cells were 25F9 negative. In addition to activation of neutrophils and macrophages, eosinophil activation has been shown to be involved in inflamed colonic mucosa.     

Changes in the enzymatic activities of beagle liver during maturation as assessed both in vitro and in vivo

1. The metabolism of 50 μM [3-¹⁴C] coumarin has been studied in a panel of 12 human liver microsomal samples of known P450 isoenzyme profile.

2. [3-¹⁴C] coumarin was metabolized by human liver microsomes to various polar products including 3-, 4- and 7-hydroxycoumarins (3-HC, 4-HC and 7-HC) 6,7-dihydroxycoumarin (6,7-DiHC), o-coumaric acid (o-CA), o-hydroxyphenyl-acetaldehyde (o-HPA), o-hydroxyphenylethanol (o-HPE), o-hydroxyphenylacetic acid (o-HPAA) and o-hydroxyphenylpropionic acid (o-HPPA) and to product(s) that bind covalently to microsomal proteins.

3. For all 12 subjects, mean rates of [3-¹⁴C] coumarin metabolism to total polar products (metabolism to all products except product(s) covalently bound to microsomal proteins), 7-HC, the 3-hydroxylation pathway (sum of 3-HC, o-HPA, o-HPE and o-HPAA), o-HPPA, 6,7-DiHC and covalent binding were 1420, 1230, 73.8, 52.5, 9.5 and 4.8 pmol/min/mg protein respectively.

4. Marked interindividual differences in [3-¹⁴C] coumarin metabolism to total polar products (30-fold variation) and 7-HC (2250-fold variation) were observed.

5. Good correlations were observed between [3-¹⁴C] coumarin metabolism and total polar products, 7-HC, o-HPPA and 6,7-DiHC, but not to 3-hydroxylation pathway products and levels of 2A6 and 2B6 in human liver microsomes.

6. [3-¹⁴C] coumarin metabolism to any polar products did not correlate with levels of 1A2, 2C8, 2C9, 2E1, 3A3/4 and 4A1 in human liver microsomes.
