A unilateral tinnitus occurred at right ear in a hypertensive and diabetic woman shortly after an ipsilateral peripheral facial palsy. Audiometric tests showed a predominant sensorineural hearing impairment at right ear. Her tinnitus was abolished after an administration of a low dose of gabapentin. In view of a controversy of gabapentin and tinnitus in previous trials, the fi ndings in this patient support that low dose gabapentin can benefi t specifi cally the subgroup of tinnitus patient with sensorineural impairment due to secondary contributing factor.

Cold-stimulus headache is a primary headache syndrome which is provoked by an external application or ingestion or inhalation of cold stimulus. It has not been reported to occur secondary to another focal structural brain lesion, or as a reversible illness. This is a report of two women who developed cold-stimulus headache on taking ice cold food after the onset of thalamic hemorrhage. The headache was typical of cold-stimulus headache except a relatively long duration of pain lasting half an hour. There was spontaneous remission after a few months. Our patients suggest that cold-stimulus headache can be secondary to thalamic hemorrhage..

Background: Nummular headache is a new category of primary headache disorder characterized by consistent location, size, and shape of painful areas. The pathogenesis is uncertain. Bifocal painful areas are rare manifestations but may expand the clinical diversity of nummular headache. Methods: The clinical characteristics of 5 bifocal nummular headache patients were reported and those of 11 patients in previous studies were reviewed. Bifocal nummular headache was classifi ed into two types. Type I was defi ned as a simultaneous activation of two painful areas while type II was defi ned as two painful areas occurring in different times. Results: All 16 patients were female, with mean age of onset and initial presentation of 54.7 years and 58.2 years, respectively. There were seven type I and nine type II patients. The parietal area, especially the tuber parietale, was the leading site of involvement in both types of patients. The shape and size of painful areas were also similar between these two groups. There was an equal frequency of ipsilateral and contralateral painful areas. The pain intensity was similar in both types of patients but was milder in new painful areas than in previous painful areas in type II patients. Conclusions: Bifocal nummular headache suggests a central role of nummular headache but does not debunk the peripheral theory of nummular headache. The accumulated fi ndings in bifocal NH patients do not support a generalization of pain occurrence or a reproduction of local process of epicranial neuralgia at multiple sites in nummular headache.

Exertional headache is one entity of Valsalva maneuver-related headache syndrome. It is usually idiopathic, but has occasionally been reported to be associated with secondary causes. However, central nervous system infection has not been mentioned before. We encountered a young man who suffered an isolated exertional headache and was found to have an active varicella-zoster virus central nervous system infection without typical intracranial hypertension or outfl ow obstruction. Intracranial vasoconstriction was detected during headache when the patient performed acute lifting or heavy exertion. The fi ndings in this patient suggest a specifi c relationship between varicella-zoster virus-related vasculopathy and exertional headache from other Valsalva maneuver-related headache syndrome

The use of pneumococcal vaccine plays an important role for prevention of invasive pneumococcal disease (IPD). However, introducing the pneumococcal vaccine into the national immunization program (NIP) is complex and costly. The strategy of progressively integrating the pneumococcal conjugate vaccine (PCV) into the NIP in Taiwan provides valuable experience for policy makers. The 7-valent PCV (PCV7) was first available in Taiwan in late 2005. PCV7 was first provided free to children with underlying diseases, those in vulnerable socioeconomic status, and those with inadequate health care resources. The catch-up immunization program with the 13-valent PCV was launched in 2013 and the national pneumococcal immunization program was implemented in 2015. Children aged 2-5 years had the highest incidence of IPD among pediatric population in Taiwan. Although the incidence of IPD caused by PCV7 serotypes has declined, the overall incidence of IPD remained high in the context of PCV7 use in the private sector. A surge of IPD caused by serotype 19A occurred, accounting for 53.6% of IPD cases among children aged < or = 5 years in 2011-2012. After the implementation of the national pneumococcal immunization program, serogroup 15 has become the leading serogroup for IPD in children. Continued surveillance is necessary to monitor the serotype epidemiology in Taiwan.

Objective: This is a review of our cases and published literature on cheiro-oral syndrome (COS), to better understand its localization, etiology and outcome. Methods: In addition to our database, we reviewed the medical database (including PUBMED, BIOSIS, EMBASE, and SCOPUS) and other sources, searched by the keyword of “cheiro-oral”. The defi nition of COS was a subjective or an objective sensory disturbance confi ned to the perioral area and the fi nger(s)/hand without a detectable abnormality in mental, motor or cerebellar function. Only cases of COS where the clinicoanatomic correlation could be identifi ed by neuroimaging study, autopsy or stereotatic surgery was included. Results: There were a total of 174 patients; 85 patients from our database, 76 patients from medical database, and 13 patients from other sources. They were 111 men and 63 women. Their age ranged from 12 to 85 years; average being 58.2 years. Stroke is the leading etiology and constituted 74% of the patients. The most common location of lesion was thalamus, followed by pons and cortex. Classical unilateral COS was seen in 81% of patients, atypical COS in 19%. Whereas the lesions were from cortex to cervical spinal cord in unilateral COS, atypical COS was associated with lesions in pons or medulla oblongata. An early deterioration was seen in 16.5% of patients, especially in large cortical infarction and subdural hemorrhage. Structural lesions were found in 85% of patients. Conclusion: Classical unilateral COS do not have a high localizing value, the atypical COS is associated with lesion in pons or medulla.

Objective:A two-dimensional (2D) in-house-built scintillator detection system (SDS) was utilized for quality assurance of the active spot scanning proton and heavy ion accelerator, aiming to establish a rapid detection method and provide reference for the quality of proton and heavy ion beam (spot position, spot size, virtual source-to-axis distance, profile depth dose distribution and beam range).Methods:The SDS consisted of a ceramic gadolinium-sulfoxylate phosphor-scintillating screen, a mirror and a commercial digital camera. The dose distribution image was obtained based on scintillator, mirror reflector and optical signal acquisition device to transform the proton and heavy ion beam into visible light through sulfur gadolinium oxide scintillator and collect visible light information to meet the clinical requirements for the quality of proton and heavy ion beam.Results:The deviation of spot position measured by multifilament proportional chamber and the SDS was less than 1mm. The differences of beam spot size measured by multifilament proportional chamber and the SDS were (1.40±0.59)mm for protons, and (0.5±0.08)mm for carbon ions. For 429.25MeV/u carbon, the virtual source-to-axis distance (V SAD) at the x-and y-axes was 751.8cm and 805.6cm. And difference between physical distance and virtual source-to-axis distance was less than 1%. The range of 287.5MeV/u carbon measured by SDS was 160mm. Conclusions:The in-house-built scintillator detector can measure beam spot position and size, virtual source, depth distribution curve and range, which can be used as an effective tool for quality assurance control of proton and heavy ion therapy.

PURPOSE: After a century, cheiro-oral syndrome (COS) was harangued and emphasized for its localizing value and benign course in recent two decades. However, an expanding body of case series challenged when COS may arise from an involvement of ascending sensory pathways between cortex and pons and terminate into poor outcome occasionally. MATERIALS AND METHODS: To analyze the location, underlying etiologies and prognosis in 76 patients presented with COS collected between 1989 and 2007. RESULTS: Four types of COS were categorized, namely unilateral (71.1%), typically bilateral (14.5%), atypically bilateral (7.9%) and crossed COS (6.5%). The most common site of COS occurrence was at pons (27.6%), following by thalamus (21.1%) and cortex (15.8%). Stroke with small infarctions or hemorrhage was the leading cause. Paroxysmal paresthesia was predicted for cortical involvement and bilateral paresthesia for pontine involvement, whereas crossed paresthesia for medullary involvement. However, the majority of lesions cannot be localized by clinical symptoms alone, and were demonstrated only by neuroimaging. Deterioration was ensued in 12% of patients, whose lesions were large cortical infarction, medullary infarction, and bilateral subdural hemorrhage. CONCLUSION: COS arises from varied sites between medulla and cortex, and is usually caused by small stroke lesion. Neurological deterioration occurs in 12% of patients and relates to large vessel occlusion, medullary involvement or cortical stroke. Since the location and deterioration of COS cannot be predicted by clinical symptoms alone, COS should be considered an emergent condition for aggressive investigation until fatal cause is substantially excluded.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) contributes to poorer short-term mortality in cirrhotic patients with ascites. However, it is unknown how long the effect of the first SBP event persists in these patients. METHODS: The National Health Insurance Database, derived from the Taiwan National Health Insurance Program, was used to identify and enroll 7,892 cirrhotic patients with ascites who were hospitalized between January 1 and December 31, 2007. All patients were free from episodes of SBP from 1996 to 2006. RESULTS: The study included 1,176 patients with SBP. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in this group were 21.8%, 38.9%, 57.5%, and 73.4%, respectively. The overall 30-day, 90-day, 1-year, and 3-year mortality rates in the non-SBP group were 15.7%, 32.5%, 53.3%, and 72.5%, respectively. After adjusting for gender, age, and other medical comorbidities, the adjusted hazard ratios of SBP for 30-day, 30- to 90-day, 90-day to 1-year, and 1- to 3-year mortality were 1.49 (95% confidence interval [CI], 1.30 to 1.71), 1.19 (95% CI, 1.02 to 1.38), 1.04 (95% CI, 0.90 to 1.20), and 0.90 (95% CI, 0.77 to 1.05), respectively, compared with the non-SBP group. CONCLUSIONS: The effect of SBP on the mortality of cirrhotic patients with ascites disappeared in those surviving more than 90 days after the first SBP event.

Human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced PSCs (iPSCs), represent potentially unlimited cell sources for clinical applications. Previous studies have suggested that hPSCs may benefit from immune privilege and limited immunogenicity, as reflected by the reduced expression of major histocompatibility complex class-related molecules. Here we investigated the global immune-related gene expression profiles of human ESCs, hiPSCs and somatic cells and identified candidate immune-related genes that may alter their immunogenicity. The expression levels of global immune-related genes were determined by comparing undifferentiated and differentiated stem cells and three types of human somatic cells: dermal papilla cells, ovarian granulosa cells and foreskin fibroblast cells. We identified the differentially expressed genes CD24, GATA3, PROM1, THBS2, LY96, IFIT3, CXCR4, IL1R1, FGFR3, IDO1 and KDR, which overlapped with selected immune-related gene lists. In further analyses, mammalian target of rapamycin complex (mTOR) signaling was investigated in the differentiated stem cells following treatment with rapamycin and lentiviral transduction with specific short-hairpin RNAs. We found that the inhibition of mTOR signal pathways significantly downregulated the immunogenicity of differentiated stem cells. We also tested the immune responses induced in differentiated stem cells by mixed lymphocyte reactions. We found that CD24- and GATA3-deficient differentiated stem cells including neural lineage cells had limited abilities to activate human lymphocytes. By analyzing the transcriptome signature of immune-related genes, we observed a tendency of the hPSCs to differentiate toward an immune cell phenotype. Taken together, these data identify candidate immune-related genes that might constitute valuable targets for clinical applications.
