Methicillin-resistant Staphylococcus aureus colony variants (SCVs) are frequently auxotrophic for hemin, menadione, thiamine, and CO2 involved in biosynthesis of the electron transport chain element. This phenotype grows slowly, and forms very small, nonhemolytic colonies in routine culture, so it may be led to the misidentification of this organism. We isolated an organism with catalase-positive, gram-positive cocci in cluster from the urine of a 55-years-old woman with persistent and relapsing bladder stone, who had undergone the antibiotic treatment with cefotaxime, ceftizoxime, amikacin, and/or micronomicin, intermittently for three years. The possibility of SCVs should have been ruled out because this organism didn't grow on Mueller-Hinton agar (MHA) for the susceptibility test. It formed small colonies on blood agar plate overnight, and grew only on MHA with supplement of hemin, or with 5% CO2. This organism was coagulase-positive, DNase-positive, manitol-salt positive, and identified as S. aureus with VITEK GPI card. The susceptibility test could be performed after adding hemin(1mg/mL) into bacterial suspension and showed susceptibility against vancomycin, teicoplanin, and rifampin. Because these phenotypes can be misidentifide as other non-pathogenic organisms due to their atypical characteristics, we should consider SCVs in case of small, nonhemolytic colonies with catalase-positive, gram-positive cocci in cluster, showing no growth on MHA. In addition, infections caused by SCVs are recently recognized in relation to persistent and relapsing infection, so they could be isolated from the patients with long-term antibiotic therapy.

Eccrine angiomatous hamartoma is a rare condition characterized histologically by increased numbers of eccrine structures and numerous capillary channels. It may be congenital or appear later in childhood. It rarely arises during puberty or adulthood. We report a case of eccrine angiomatous hamartoma on the left shoulder in a 34-year-old man. The patient presented with asymptomatic, dome-shaped, about 3X2.5 cm, reddish telangiectatic nodule on the left shoulder. Histological examination showed an increased numbers of eccrine sweat glands and vascular structures.

Acute cerebral infarctions are rare in children, however, they can occur as a complication of a Mycoplasma pneumoniae (MP) infection due to direct invasion, vasculitis, or a hypercoagulable state. We report on the case of a 5-year-old boy who had an extensive stroke in multiple cerebrovascular territories 10 days after the diagnosis of MP infection. Based on the suspicion that the cerebral infarction was associated with a macrolide-resistant MP infection, the patient was treated with levofloxacin, methyl-prednisolone, intravenous immunoglobulin, and enoxaparin. Despite this medical management, cerebral vascular narrowing progressed and a decompressive craniectomy became necessary for the patient's survival. According to laboratory tests, brain magnetic resonance imaging, and clinical manifestations, the cerebral infarction in this case appeared to be due to the combined effects of hypercoagulability and cytokineinduced vascular inflammation.

Speckled lentiginous nevus is circumscribed patch of hyperpigmentation with smaller, darker pigmented macules or papules within the patch. The background shows histologic features of lentigo simplex. The speckled areas show junctional or compound nevus. Association of speckled lentiginous nevus with multiple spitz nevi was rarely reported. We report a case of multiple spitz nevi arising in a giant speckled lentiginous nevus.

We investigated the comparative effects of electroacupuncture (EA) with different frequency on the spinal c-fos and inotropic glutamate receptor expression in carrageenan-injected rats. Bilateral EA stimulation with 2, 15 and 120 Hz were delivered at those acupoints corresponding to Zusanli and Sanyinjiao in man via the needles. The inhibitory effects of the EA on the inflammatory process were investigated in the central nociceptive sites by immunohistochemical analysis. Three hours after carrageenan injection, the number of c-fos-like immunoreactive (LI) neurons was significantly increased in all layers of the ipsilateral spinal cord at L4-5 segment. But these immunoreactive neurons were markedly reduced in the spinal gray matter, especially in the superficial laminae, by all kinds of EA stimulation. The number of NMDA (NR-1 and NR-2A) and AMPA receptors (GluR-1, GluR-2/3) -LI neurons was also increased by carrageenan injection. But NR-2A-LI neuron was significantly reduced in superficial laminae of dorsal horn by 2 Hz EA stimulation. While GluR-1-LI neuron of 15 Hz and 120 Hz EA was increased in the nucleus proprius compared with carrageenan-injected group, GluR-2/3-LI neuron of these EA stimulated groups significantly reduced in superficial laminae of dorsal horn. In conclusion, EA treatment can attenuate spinal c-fos expression in carrageenan injected rats and regulates spinal inotropic glutamate receptor expression.

BACKGROUND: Recent reports suggest that the intake of vitamin D and calcium may influence insulin resistance. The aim of this study was to assess the effects of vitamin D and calcium intervention on the improvement of blood glucose and insulin resistance in patients with type 2 diabetes mellitus (DM). METHODS: Fasting blood glucose, glycosylated hemoglobin A1c (HbA1C), serum 25(OH)D3, serum lipid levels, insulin secretion, and activity and dietary surveys were analyzed in type 2 DM patients both before and after a 12-week vitamin D and calcium intake intervention. RESULTS: The serum 25(OH)D3 level was found to be negatively correlated with insulin resistance and fasting blood glucose. Calcium intake level was also negatively correlated with insulin resistance. Fasting blood glucose, HbA1C, and HOMA-IR decreased significantly (P <0.05) following vitamin D and calcium intake intervention in the medical nutrition therapy (MNT) group, while there was no such change observed in the control group. Dietary calcium and vitamin D intakes were significantly (P <0.05) higher in the MNT group than in the control group. The concentrations of serum 25(OH)D3 and insulin secretion increased slightly in the MNT group following the 12-week intervention; however, these results did not reach statistical significance. CONCLUSION: The results of the present study indicate that calcium and vitamin D intervention may be helpful in improving fasting blood glucose, HbA1C, serum 25(OH)D3 and HOMA-IR in patients with type 2 DM who have insufficient serum 25(OH)D3 concentrations.

Cosmetic lateral canthoplasty, in which the size of the eye is increased by extending the palpebral fissure and decreasing the degree of the eye slant, has become a prevalent procedure for East Asians. However, it is not uncommon for there to be complications or unfavorable results after the surgery. With this in mind, the authors have designed a surgical method to reduce complications in cosmetic lateral canthoplasty by preserving the lateral canthal angle. We discuss here the anatomy required for surgery, the surgical methods, and methods for reducing complications during cosmetic lateral canthoplasty.
