It is challenging to treat ventriculitis with parenteral treatment alone in some cases because of the difficulty involved in maintaining an appropriate level of antibiotics in cerebrospinal fluid (CSF). We report two cases of ventriculitis who did not respond to intravenous (IV) antibiotics but were successfully treated with intraventricular antibiotics using IV agents. The first case was a four-month-old male patient with X-linked hydrocephalus.He showed ventriculitis due to Klebsiella pneumoniae not producing extended-spectrum β-lactamase and susceptible to third-generation cephalosporins and gentamicin, following ventriculoperitoneal (VP) shunt. His condition did not improve during the 47 days of treatment with IV cefotaxime and meropenem. We achieved improvement in clinical presentation and CSF profile after three times of intraventricular gentamicin injection. The patient was discharged from the hospital with antiepileptic drugs. The second case was a six-month-old female patient with a history of neonatal meningitis complicated with hydrocephalus at one month of age, VP shunt at two months of age, followed by a methicillinresistant coagulase-negative staphylococci (CoNS) shunt infection with ventriculitis after the shunt operation. CoNS ventriculitis recurred four weeks later. We failed to treat intractable methicillin-resistant CoNS ventriculitis with IV vancomycin for ten days, and thus intraventricular antimicrobial treatment was considered. Five times of intraventricular vancomycin administration led to improvement in clinical parameters. There were only neurological sequelae of delayed language development but no other major complications. Patients in these two cases responded well to intraventricular antibiotics, with negative CSF culture results, and were successfully treated for ventriculitis without serious complications.

Acrodermatitis continua of Hallopeau (ACH) is a rare form of acropustular eruption characterized by a presence of aseptic pustules on inflammatory periungual or subungual regions. Frequently accompanied by paronychia, atrophic skin changes, onychodystrophy, and osteolysis of distal phalanges of the digits, it is considered to be a variant of pustular psoriasis with a chronic relapsing course and refractoriness to many therapeutic modalities. Here, we present a case of a 45-year-old female who presented with multiple pustules pathologically diagnosed as pustular psoriasis on her left thumb. She suffered from ACH for over a decade, and in the process experienced frequent relapses and showed poor response to numerous treatment modalities such as narrow band UVB, topical steroid, steroid intralesional injection, oral retinoids, 308 nm excimer laser, and oral immune suppressants. However, the patient showed dramatic clinical improvements to administration of etanercept (TNF-alpha antagonist, twice a week) for a period of one month. The cessation of etanercept led to recurrence of symptoms and marked deterioration of the skin lesion within a month again, but the re-initiation of treatment soon relieved the problem. After completion of a three months trial of etanercept, the cutaneous lesion subsided, and the patient is now successfully controlled with topical steroid maintenance therapy. Hereby, we report a patient with ACH successfully treated with etanercept.

OBJECT: The purpose of this study was to investigate that infection with group A[beta] hemolytic streptococcus may associate the mechanisms that cause or exacerbate some cases of Tourette's disorder and to evaluate the treatment effect of IG therapy, comparing between IG therapy and drug therapy. METHOD: The subjects were divided into three groups composing of the groups with increasing level of ASO titer and the group with normal level of ASO titer, treating with antipsychotics. Children with infection-triggered exacerbation of Tourette's disorder were assigned treatment with IVIG (400mg/kg/daily on 5 consecutive days) or antipsychotic drugs. Symptom severity was rated at baseline, and at 4weeks, at at 8weeks after treatment by use of standard assessment scale of tics. RESULTS: 1) The motor tic score, global severity scores and overall TS impairment rating scores of YGTSS in the group with incresing level of ASO titer were related with ASO titer. 2) Immune therapy was more effective in the group with incresing level of ASO titer than antipsychotic drug therapy. CONCLUSION: These results suggest that increasing level of ASO titer, resulting from group A[beta] hemolytic streptococcal infection has affected worsening the tic symptoms in Touette's disorder and in group with increasing level of ASO titer, IVIG therapy is more effective than drug therapy.

Objectives:
Remote ischemic preconditioning (rIPC) is a novel technique in which brief episodes of ischemia and reperfusion in one organ confer protection against prolonged ischemia in a distant organ.In contrast, anesthetic-induced preconditioning (APC) utilizes volatile anesthetics to protect multiple organs from ischemia-reperfusion injury. Both methods are easily integrated into various clinical scenarios for cardioprotection. However, it remains unclear whether simultaneous application of these techniques could result in complementary, additive, synergistic, or adverse effects.
Methods:
An adult rabbit heart Langendorff model of global ischemia/reperfusion injury was used to compare the cardioprotective effect of rIPC and APC alone and in combination relative to untreated (control) hearts. The rIPC group underwent four cycles of 5-minute ischemia on the hind limb, each followed by 5 minutes of reperfusion. The APC group received 2.5 vol% sevoflurane for 20 minutes via a face mask, followed by a 20-minute washout period.
Results:
Both in vivo rIPC, induced by four 5-minute cycles of ischemia/reperfusion on the hind limb, and APC, administered as 2.5 vol% sevoflurane via a mask, significantly reduced the size of myocardial infarction following 30 minutes of global ischemia by >50% compared to the untreated control group (rIPC, 12.1±1.7%; APC, 13.5±2.1%; P<0.01 compared to control, 31.3±3.0%). However, no additional protective effect was observed when rIPC and APC were combined (rIPC+APC, 14.4±3.3%).
Conclusion
Although combining rIPC and APC did not provide additional protection, there was no inhibitory effect of one intervention on the other.
