The aim of the study is to investigate the association between cerebral white matter hyperintensity (WMH) and the functional improvement using the Korean version of Modified Barthel Index (K-MBI) score during inpatient stroke rehabilitation. One hundred sixty participants were divided into 2 groups based on the severity of WMH according to Fazekas scale: Mild WMH group was defined as patients with Fazekas scale 0 and 1, and severe WMH group was defined as Fazekas scale 2 and 3. Functional status was assessed using the K-MBI score, and functional gains were calculated from the K-MBI score. The absolute functional gain in mild WMH group was significantly higher compared to severe WMH group (p < 0.05). In addition, patients in mild WMH had higher absolute functional efficiency, rehabilitation effectiveness, and relative functional efficiency. In the generalized linear model analyses, there was an association between functional outcomes and severity of WMH. In this study, the severity and extent of WMH are significantly correlated with poor functional improvement in patients with ischemic stroke. The WMH could be considered as one of many factors that can influence functional recovery during rehabilitation of stroke.

OBJECTIVE: To investigate whether the polymorphisms of CASP3 gene (rs4647602, intron A/C and rs1049216, UTR C/T) and CASP9 gene (rs1052576, Gln/Arg G/A and rs1052571, Ser/Val T/C) were associated with the development, and clinical severity of ischemic stroke and functional consequences after stroke. METHODS: Genomic DNA from 121 ischemic stroke patients and 201 healthy control subjects were extracted, and polymerase chain reaction products were sequenced. To investigate the association of polymorphisms and the development, and National Institutes of Health Stroke Scale (K-NIHSS), logistic regression models were analyzed. RESULTS: Polymorphism of the untranslational region of CASP3 (rs1049216, UTR C/T) has been associated with the development of ischemic stroke—in codominant1 model (odds ratio [OR], 0.51; 95% confidence interval [CI], 0.29–0.88; p=0.017), in dominant model (OR, 0.57; 95% CI, 0.34–0.97; p=0.034), and in the overdominant model (OR, 0.50; 95% CI, 0.29–0.87; p=0.011). A missense SNP of CASP9 gene (rs1052571, Ser/Val T/C) was associated with the development of ischemic stroke (OR, 1.93; 95% CI, 1.05–3.55; p=0.034 in recessive model). CONCLUSION: These results indicate the possibility that CASP3 and CASP9 genes are markers for the development of ischemic stroke.

OBJECTIVE: To evaluate the relationships between tongue pressure and different aspects of the oral-phase swallowing function. METHODS: We included 96 stroke patients with dysphagia, ranging in age from 40 to 88 years (mean, 63.7 years). Measurements of tongue pressure were obtained with the Iowa Oral Performance Instrument, a device with established normative data. Three trials of maximum performance were performed for lip closure pressure (LP), anterior hard palate-to-tongue pressure (AP), and posterior hard palate-to-tongue pressure (PP); buccal-to-tongue pressures on both sides were also recorded (buccal-to-tongue pressure, on the weak side [BW]; buccal-to-tongue pressure, on the healthy side [BH]). The average pressure in each result was compared between the groups. Clinical evaluation of the swallowing function was performed with a videofluoroscopic swallowing study. RESULTS: The average maximum AP and PP values in the intact LC group were significantly higher than those in the inadequate lip closure group (AP, p=0.003; PP, p<0.001). AP and PP showed significant relationships with bolus formation (BF), mastication, premature bolus loss (PBL), tongue to palate contact (TP), and oral transit time (OTT). Furthermore, LP, BW, and BH values were significantly higher in the groups with intact mastication, without PBL and intact TP. CONCLUSION: These findings indicate that the tongue pressure appears to be closely related to the oral-phase swallowing function in post-stroke patients, especially BF, mastication, PBL, TP and OTT.

OBJECTIVE: Greater occipital nerve block (GONB) is a widely accepted treatment of primary headaches. Two ultrasound (US)-guided blockade techniques exist: 1) the classical distal nerve block technique performed medial to the occipital artery at the superior nuchal line, and 2) the new proximal nerve block technique performed at the obliquus capitis inferior muscle at the level of C2. Our study aim was to perform a head-to-head comparative study of these two US-guided techniques.METHOD: Forty-nine patients with primary headache treated in our university hospital were recruited. Patients were randomized into two groups of the classical nerve block and the new proximal nerve block techniques. The headache questionnaire was made to assess the intensity of the pain of headache attacks, number of days they experience headache, duration of headache, and amount of pain medication they consumed.RESULTS: In both groups, a decrease in the severity and frequency of the headache was observed. There was no measurable difference in outcome between the two groups.CONCLUSION: Our study showed that the classic and new proximal techniques are equally effective in decreasing the headache severity and frequency.
