PURPOSE: To compare the clinical characteristics and laboratory finding between adenoviral and group A streptococcal (GAS) pharyngitis. METHODS: A retrospective review of medical records was performed in the patients with adenovirus infection among those who were admitted for febrile respiratory disease from January 2011 to July 2013 and GAS pharyngitis among those who visited for symptoms of scarlet fever from August 2006 to July 2013. RESULTS: 179 patients (AV1 group) were diagnosed with adenoviral pharyngitis and 37 (AV2 group) of these patients had adenovirus single infection. 26 patients (GAS group) were diagnosed with scarlet fever. Adenoviral infection (AV2 group) developed in younger patients compared to GAS group (2.8+/-2.1 years vs. 5.4+/-1.8 years, P=0.000). Total durations of fever and admission were longer in AV2 (6.3+/-2.6 days vs. 3.3+/-1.9 days, P=0.000; 4.1+/-1.2 days vs. 1.9+/-1.8 days, P=0.000, respectively). WBC counts were higher in AV2 (11,449+/-5,680 cells/mm2 vs. 6,722+/-6,941 cells/mm2, P=0.000). CRP was not significantly different between AV2 and GAS group (3.8+/-3.2 mg/dL vs. 5.2+/-5.1 mg/dL, P=0.368). No difference was found between two groups in the percentage of antibiotics use (91.9% vs. 100%, P=0.261). CONCLUSION: Clinical characteristics and measures of inflammation in the laboratory findings were similar between adenoviral and GAS pharyngitis group. It is necessary to conduct the test for respiratory virus and bacteria in early stage to differentiate in the pharyngitis patients with leukocytosis and elevation of CRP level.

Purpose:
Proton beam therapy (PBT) is a state-of-the-art technology employed in radiotherapy (RT) for cancer patients. This study characterized how PBT has been used in clinical practice in Korea.
Materials and Methods:
Patients who received any type of RT between 2007 and 2019 were identified from the radiation oncology registry of the two PBT facilities operating in Korea (National Cancer Center and Samsung Medical Center). The chi-square test was used to identify patient- and treatment-related characteristics associated with the receipt of PBT.
Results:
A total of 54,035 patients had been treated with some form of RT in the two institutions, of whom 5,398 received PBT (10.0%). The number of patients who receive PBT has gradually increased since PBT first started, from 162 patients in 2007 to 1,304 patients in 2019. Among all types of cancer, PBT use in liver cancer has been steadily increasing from 20% in 2008-2009 to 32% in 2018-2019. In contrast, that in prostate cancer has been continuously decreasing from 20% in 2008-2009 to < 10% in 2018-2019. Male sex, very young or old age, stage I-II disease, residency in non-capital areas, a definitive setting, a curative treatment aim, enrollment in a clinical trial, re-irradiation and insurance coverage were significantly associated with the receipt of PBT (all p < 0.05).
Conclusion
Since PBT started in Korea, the number of patients receiving PBT has increased to more than 1,000 per year and treatment indications have expanded. Liver cancer is the most common primary tumor among all PBT cases in Korea.

BACKGROUND AND PURPOSE: High-sensitivity C-reactive protein (hs-CRP) is the most widely studied biomarker of systemic inflammation. Its level has been reported to be associated with cognitive impairment. While dementia and cognitive impairment are common non-motor symptoms in advanced idiopathic Parkinson's disease (PD), the clinical value of hs-CRP for predicting dementia in PD patients remains unclear. Therefore, the objective of this study was to clarify the relationship between hs-CRP levels and the development or progression of dementia in PD through evaluating hs-CRP levels in PD patients with or without dementia. METHODS: A total of 112 PD patients without dementia (PD-D), 103 PD patients with dementia (PD+D), and 94 healthy controls were used in this study. The levels of hs-CRP and cognitive function were analyzed among these three groups. RESULTS: The mean serum hs-CRP levels in PD-D and PD+D were 1.76+/-3.62 mg/dL and 1.44+/-2.78 mg/dL, respectively, which were significantly (p=0.02) higher than that (vs. 0.41+/-1.06 mg/dL) in healthy controls. However, the levels of hs-CRP were not significantly (p>0.05) different between PD-D and PD+D. CONCLUSIONS: Our results suggest that neuro-inflammation plays a role in the pathogenesis of PD. However, it does not significantly contribute to the development or the progression of dementia in PD patients.

BACKGROUND: We performed a prospective, double blind study to compare the clinical effect of vertical infraclavicular brachial plexus block produced by 0.5% levobupivacaine and 0.5% ropivacaine for upper limb surgery. METHODS: We included 60 patients receiving upper limb surgery under infraclavicular brachial plexus block. The infraclavicular brachial plexus block was performed via the vertical technique with 30 ml of 0.5% levobupivacaine or 0.5% ropivacaine. We observed which nerve type was stimulated and scored the sensory and motor block. The quality of block was assessed intraoperatively. The duration of sensory and motor block and complications were assessed. RESULTS: There were no significant differences in frequencies of stimulated nerve type, evolution of sensory and motor block quality, or success of block. There were no significant difference in duration of sensory block, but duration of motor block was prolonged after 0.5% levobupivacaine. There were no complications. CONCLUSIONS: Both 0.5% levobupivacaine and 0.5% ropivacaine had similar effects in the vertical infraclavicular brachial plexus block.

BACKGROUND: Alzheimer's disease (AD) is a representative neurodegenerative disorder associated with memory disturbance. Recent research has shown that risk factors for cerebrovascular disorders are also causes of dementia. Of these risk factors, hyperhomocysteinemia is well known to be positively correlated with all types of dementias including AD. But it is not clear if there is a difference in the concentration of homocysteine according to subtypes of memory impairment of AD. We performed this study to explore the relationship between homocysteine and memory. METHODS: A total of 54 patients (male: 15 patients) to the dementia clinic at our hospital were recruited for this study. All subjects underwent neuropsychological tests including detailed memory function tests and brain magnetic resonance images. The plasma homocysteine level was measured routinely in all patients. RESULTS: Verbal and visual memories in AD were significantly associated with the concentration of plasma homocysteine. The plasma homocysteine level was significantly correlated with delayed recalls of verbal and visual memories and recognition of visual memory. However, there was no relationship between plasma homocysteine and working memory. CONCLUSIONS: This study showed that plasma homocysteine level was related to the consolidation and retrieval stage of memory in AD. Therefore, we cautiously assumed that control of plasma homocysteine level could contribute to management for the prevention of cognitive impairment.

BACKGROUND: Clinical diagnosis of multiple system atrophy (MSA) relays on signs and symptoms that are often difficult to identify particularly at early stage. Indeed neuropathological studies have demonstrated that Parkinson variant of MSA (MSA-P) is the first cause of misdiagnosis in a cohort of patients presenting with parkinsonian features. But accurate diagnosis of these disorders is important for deciding on treatment, appropriate advice and prognosis since atypical parkinsonian disorders are characterized by poor response to dopaminergic treatment and more rapid disease progression. Therefore, we conducted this study to investigate difference of perfusion Single Photon Emission Computed Tomography (SPECT) in patients with the early phase of MSA-P using SPM program. METHODS: We recruited consecutively 21 patients with MSA-P and 48 age-matched healthy controls. All subjects underwent Tc-99m HMPAO perfusion SPECT and this perfusion images were analyzed. RESULTS: For MSA-P, only hypoperfusion was seen in the middle frontal gyrus of left frontal lobe, superior frontal gyrus of right frontal lobe, precentral gyrus of left frontal lobe, middle frontal gyrus of right frontal lobe and precentral gyrus of right frontal lobe with respect to healthy subjects. CONCLUSIONS: We cautiously assume that perfusion SPECT may offer significant advantages compared to other imaging techniques in the assessment of neuronal degeneration in MSA-P and may help the clinician in the diagnostic characterization of patients presenting with atypical parkinsonism.

Endometriosis of the rectum is unusual condition, since it represents an invasion of previously normal bowel by hormone-dependent nonmalignant cell from uterus of the same patient. It is estimated that the incidence of endometriosis is about 8-15% of reproductive women, of whom 3-34% show intestinal invasion of rectosigmoid colon, appendix, ileum, and cecum in order of decreasing frequency. Symptoms related bowel involvement may vary from none to complete intestinal obstruction. Because the mucosa is involved infrequently there is rarely rectal bleeding. X-ray and sigmoidoscopic studies are usually negative. It was not reported that colonic endometriosis was confirmed by endoscopic biopsy. Recently we experienced a case of rectal endometriosis which presented itself as a cyclic rectal bleeding with abdominal pain and diagnosed by colonoscopic biopsy.

BACKGROUND: Ropivacaine and levobupivacaine, both single S-enantiomers, show less toxicity on the central nervous and cardiovascular system than racemic bupivacaine. Earlier studies have shown that levobupivacaine and bupivacaine are almost equipotent while ropivaciane was 60% less potent than bupivacaine. The aim of this prospective, double blinded study was to compare the clinical efficacy and safety of epidural anesthesia produced by 0.5% levobupivacaine and 0.5% ropivacaine for a cesarean section. METHODS: Sixty-two parturients undergoing an elective cesarean section were randomized to receive either epidural levobupivacaine 0.5% 20 ml (n = 31) or epidural ropivacaine 0.5% 20 ml (n = 31). Surgery was commenced when the sensory block had reached the dermatome level, T6. The onset, duration, quality of the sensory and motor block and abdominal muscle relaxation were evaluated. The blood pressure and heart rate of the mother and neonatal outcome, as assessed by the Apgar score and umbilical pH, were also recorded. RESULTS: There was no difference in the onset time, the segmental spread of sensory block and analgesic supplement between the two groups. However, levobupivacaine produced a longer duration of sensory block than ropivacaine (levobupivacaine 224.1 +/- 66.6 min, ropivacaine 176.5 +/- 32.8 min, P < 0.05). The onset time (except Bromage scale 2), intensity and duration of the motor block and muscle relaxation were similar in both groups. There was no difference in the maternal and neonatal outcomes between the two groups. CONCLUSIONS: 0.5% levobupivacaine and 0.5% ropivacaine produced equivalent efficacy and safety in epidural anesthesia for a cesarean section, but levobupivacaine resulted in a longer duration of sensory block.

This study evaluated the efficacy of an office bleaching gel (RemeWhite, Remedent Inc., Deurle, Belgium) containing 30% hydrogen peroxide. 31 volunteers were recieved office bleaching with the RemeWhite for 3 times at one visit, total 2 visits. As control group, the same gel in which hydrogen peroxide was not included was applied to 31 volunteers with the same protocol. The shade change (DeltaE*, color difference) of 12 anterior teeth was measured using Colorimerter and Vitapan classical shade guide. The shade change of overall teeth in the experimental group was significantly greater than that in the control group which was measured using Colorimeter. There was also a significant difference between baseline and 14 weeks or 26 weeks though color rebounding phenomenon occurred as time went by. Small shade change difference can be measured accurately using Colorimeter than using Vitapan classical shade guide.
