Purpose:
To evaluate the association between long-term glycated hemoglobin A (HbA1c) variability and treatment outcomes ofanti-vascular endothelial growth factor (VEGF) injection in diabetic macular edema patients.
Methods:
The medical records of 49 eyes (38 patients) that received anti-VEGF injection for diabetic macular edema were reviewedretrospectively. Best-corrected visual acuity (BCVA) and central macular thickness (CMT) before injection and at onemonth and six months after injection were analyzed. HbA1c variability (HbA1c coefficient of variation [CV]) was calculated usingthe HbA1c results from the year prior to (before) and the year after injection and compared with clinical results.
Results:
In the group with a low mean HbA1c level before injection, the group with lower HbA1c CV showed greater reduction inmacular edema one month after injection (low HbA1c CV, 122.4 ± 123.2 μm versus high HbA1c CV, 5.2 ± 37.0 μm, p= 0.027).In the group with high mean HbA1c, there was no significant difference between HbA1c variability and clinical features. In a multivariateanalysis, the factor related to the reduction of macular edema was initial CMT (one month adjusted hazard ratio (aHR)0.5, p< 0.001; six months aHR 0.3, p= 0.023). The factor associated with visual gain was initial visual acuity (LogMAR) (onemonth aHR 0.4, p< 0.001; six months aHR 0.4, p< 0.001). The association between mean HbA1c or HbA1c variability and clinicaloutcome was not significant.
Conclusions
Unlike initial CMT or BCVA, mean HbA1c and HbA1c variability were not significantly associated with clinical outcomesof anti-VEGF injection in diabetic macular edema patients.

Hiccups may be considered a form of myoclonus of diaphragm. Valproic acid has been considered the drug of choice in treatment of intractable hiccups; however, its various adverse events limit its use in the clinical basis, especially in elderly or complicated patients. Levetiracetam was known as a safe antiepileptic drug. However, the anti-hiccup property of the levetiracetam has been rarely reported. We report a 69-year old male patient who developed sudden persistent hiccups and was successfully treated with levetiracetam. Levetiracetam should be considered as alternative treatment option in selected patients with intractable hiccups.

Background: Little is known regarding the functional outcome and quality of life of neuro-ICU
survivors. In Korea, the neuro-ICU concept was introduced relatively late and data about long term
outcome and predictors concerning functional outcome is scarce. The main objective of this study was
to analyze functional outcome and mortality, and to determine prognostic predictors for the outcome
in patients admitted to Korean neuro-ICUs. Methods: Consecutive adult (≥ 15-years-of-age) patients
admitted to a neuro-ICU due to various causes including ischemic or hemorrhagic stroke, and other
neurological or neurosurgical problems such as traumatic brain injury, seizure, or drug intoxication
during an 18-month period from July 2008 through December 2009 were included. Demographic and
clinical variables were compared between groups stratifi ed based on 6-month modifi ed Rankin scale
score. Results: Of 555 patients, there were signifi cant differences in age (P=0.013), sex (P=0.02),
hospital stay (P<0.01), neuro-ICU stay (P<0.01), admission diagnosis (P=0.001), intubation (P<0.01),
mechanical ventilation (P<0.01), tracheostomy (P<0.01), comorbid conditions such as atrial fi brillation
(P<0.01), cardiac complication (P<0.01) and pulmonary complication (P<0.01), a high Therapeutic
Intervention Scoring System (TISS-28) score (P<0.01), and a high Acute Physiology and chronic health
evaluation (APACHE) II score (P<0.01) between favorable and unfavorable outcome groups. The
overall mortality rate was 15.0% (n=83). In multivariable logistic regression analysis, age, sex, high
TISS-28, high APACHE II score, intubation, and cardiac complication were independent predictors
of unfavorable outcome.
Conclusion: The identifi ed predictors for functional outcomes in Korean neuro-ICU patients will be
an important aid in diagnosing and treating neuro-ICU patients.

Purpose:
To predict the presence of tractional retinal detachment (TRD) in eyes with dense vitreous hemorrhage (VH) and proliferative diabetic retinopathy (PDR) by evaluating the status of posterior vitreous detachment (PVD) in fellow eyes using optical coherence tomography (OCT).
Methods:
A total of 44 eyes from 22 patients who underwent vitrectomy due to dense VH with PDR were enrolled. Using OCT, the PVD status in the fellow eye was divided into two groups (incomplete and complete PVD). The incomplete PVD group included eyes without PVD and eyes with partial PVD. B-scan ultrasonography was performed on eyes with dense VH to evaluate the presence of TRD. Both OCT and B-scan images were reviewed by four ophthalmologists (two novices and two experienced), and the interobserver agreement was evaluated.
Results:
There was a difference in the interobserver agreement regarding the presence of TRD in eyes with dense VH evaluated by B scan between novice and experienced ophthalmologists (novice, κ = 0.421 vs. experienced, κ = 0.814), although there was no difference between novice and experienced ophthalmologists in the interobserver agreement regarding the status of PVD in the fellow eye evaluated by OCT (novice, κ = 1.000 vs. experienced, κ = 1.000). All observed TRD during vitrectomy occurred in eyes with incomplete PVD in the fellow eye. Logistic regression analysis revealed a statistically significant relation between TRD and the age of the patient (odds ratio [OR], 0.874; p = 0.047), and between TRD and incomplete PVD in the fellow eye evaluated by OCT (OR, 13.904; p = 0.042).
Conclusions
Evaluation of the PVD status in the fellow eye using OCT may be a useful predictor for detecting the presence of TRD in eyes with dense VH and PDR.

Candida species is indigenous fungus of healthy individuals, and frequently found in sputum culture. Candida isolation from the respiratory tract is not generally considered as a marker of lung infection, and definitive diagnosis of Candida pneumonia is confirmed by tissue biopsy. A few cases of Candida pneumonia pathologically confirmed by transthoracic needle aspiration of mycetoma have been reported. In Korea, a case of Candida pneumonia diagnosed by bronchial washing and blood culture was reported, but there is no case report diagnosed by biopsy. We report a case of Candida pneumonia diagnosed by endobronchial biopsy, and antifungal therapy resulted in successful resolution of the pneumonia.

An endolichenic fungus Xylaria grammica EL000614 produces grammicin, a potent nematicidal pyrone derivative that can serve as a new control option for root-knot nematodes. We optimized an Agrobacterium tumefaciens-mediated transformation (ATMT) protocol for X.grammica to support genetic studies. Transformants were successfully generated after co-cultivation of homogenized young mycelia of X.grammica with A. tumefaciens strain AGL-1 carrying a binary vector that contains the bacterial hygromycin B phosphotransferase (hph) gene and the eGFP gene in T-DNA. The resulting transformants were mitotically stable, and PCR analysis showed the integratin of both genes in the genome of transformants.Expression of eGFP was confirmed via fluorescence microscopy. Southern analysis showed that 131 (78.9%) out of 166 transformants contained a single T-DNA insertion. Crucial factors for producing predominantly single T-DNA transformants include 48 h of co-cultivation, pretreatment of A. tumefaciens cells with acetosyringone before co-cultivation, and using freshly prepared mycelia. The established ATMT protocol offers an efficient tool for random insertional mutagenesis and gene transfer in studying the biology and ecology ofX.grammica.

BACKGROUND: Co-morbid vascular disease, such as coronary artery disease or peripheral artery disease (PAD) is frequently combined in patients with ischemic stroke (IS) or transient ischemic attack (TIA). However, PAD has been underestimated and underevaluated in these patients. The aims of this study were to know the prevalence of PAD and to assess the risk factors for PAD in patients with IS or TIA. METHODS: Between February in 2006 and March in 2011, ankle-brachial index (ABI) was measured in 724 patients with acute IS or TIA. We compared the demographics and baseline characteristics, including risk factors and stroke subtypes between patients combined with and without PAD. RESULTS: PAD was found in 13.3% (96/724) and more frequent in patients with large artery disease. Patients with PAD were older (mean age 74.5+/-10.4 vs. 65.5+/-12.5, p<0.001),and had higher body mass index (BMI) (23.15+/-3.46 vs. 24.03+/-3.25; p=0.019), higher serum level of hemoglobin (12.99+/-2.12 vs. 13.68+/-1.87; p=0.001) and severe initial neurological deficit measured by National Institute of Health Stroke Scale (NIHSS) (median 4, IQR:2,7 vs. 2, IQR:1,5; p=0.001) on admission than those without PAD; patients with PAD were more likely to have hypertension (79.2% vs. 61.6%; p=0.001), diabetes (44.8% vs. 29.5%; p=0.004), and previous stroke or TIA (35.4% vs. 23.9%; p=0.022). In multivariable logistic regression analysis, age (OR, 1.069; 95% CI, 1.042-1.096; p<0.001) and diabetes (OR, 1.904; 95% CI, 1.134-3.196; p=0.015) were independently associated with PAD in IS or TIA. CONCLUSIONS: Age and diabetes were independent risk factors for PAD in IS or TIA.

BACKGROUND: Miliary tuberculosis (TB) can cause diagnostic confusion for clinicians because its radiological appearance can resemble that of metastatic cancer. CASE REPORT: Here, we describe the case of a 72-yearold woman with miliary TB mimicking brain metastasis from renal cell carcinoma. The patient visited our clinic because of dysarthria and sluggish speech. A metastatic cancer such as renal cell carcinoma or brain tumor was suspected. However, the patient was diagnosed with miliary TB associated with multiple intracranial tuberculomas and a subsequent paradoxical response to anti-TB therapy. CONCLUSION: Clinicians should be aware that miliary TB can mimic metastatic cancer even in older people, especially in TB-endemic regions.

Neurocritical patients who can self-report pain use the 0-10 numerical rating scale (NRS, verbal or visual form). However, critically ill patients whose nervous systems cannot express pain use the behavioral pain scale (BPS) and the critical care pain observation tool (CPOT) behavioral pain assessment tools. These tools reveal pain-related changes in movement, facial expression, posture, and physiological indicators such as heart rate, blood pressure, and respiratory rate. In pain control, it is first essential to reduce unnecessary painkillers through non-drug therapy and maximize the effect of the administered analgesics. For nonneuropathic pain, narcotic analgesics such as fentanyl, hydromorphone, morphine, and remifentanil are administered intravenously. Gabapentin, pregabalin, and carbamazepine are recommended along with narcotic analgesics for neuropathic pain control. In addition, nonnarcotic analgesics for multi-modal analgesia are used to reduce the use of narcotic analgesics or the side effects of narcotic analgesics. In the intensive care unit (ICU), the sedation-agitation scale (SAS) and the Richmond agitation-sedation scale (RASS) are used to determine the depth of sedation to be maintained during shallow or deep sedation, considering the condition of the critically ill patient. When selecting sedatives for critically ill patients, preferentially consider nonbenzodiazepines such as propofol or dexmedetomidine rather than benzodiazepines such as midazolam or lorazepam. In addition, patients use painkillers or sedatives for over a week, and neurological changes or physiological dependence may occur. Therefore, clinicians should evaluate the critically ill patient’s condition, and sedatives and painkillers should be reduced or discontinued.
