Safety and Efficacy of Intravenous Thrombolysis in the 3- to 4.5-hour Window in Acute Ischemic Stroke Patients Who Have Both Diabetes Mellitus and History of Prior Stroke

Background@#For acute ischemic stroke (AIS) patients with history of prior stroke (PS) and diabetes mellitus (DM), intravenous recombinant tissue plasminogen activator (IV-tPA) therapy in the 3- to 4.5-hour window is off-label in Korea. This study aimed to assess the safety and efficacy of IV-tPA in these patients. @*Methods@#Using data from a prospective multicenter stroke registry between January 2009 and March 2021, we identified AIS patients who received IV-tPA in the 3- to 4.5-hour window, and compared the outcomes of symptomatic intracranial hemorrhage (SICH), 3-month mortality, 3-month modified Rankin Scale (mRS) score 0-1 and 3-month mRS distribution between patients with both PS and DM (PS/DM, n=56) versus those with neither PS nor DM, or with only one (non-PS/DM, n=927). @*Results@#The PS/DM group versus the non-PS/DM group was more likely to have a prior disability, hypertension, hyperlipidemia, coronary heart disease and less likely to have atrial fibrillation. The PS/DM and the non-PS/DM groups had comparable rates of SICH (0% vs. 1.7%; p>0.999) and 3-month mortality (10.7% vs. 10.2%; p=0.9112). The rate of 3-month mRS 0-1 was non-significantly lower in the PS/DM group than in the non-PS/DM group (30.4% vs. 40.7%; adjusted odds ratio [95% confidence interval], 0.81 [0.41-1.59]). @*Conclusions@#In the 3- to 4.5-hour window, AIS patients with PS/DM, as compared to those with non-PS/DM, might benefit less from IV-tPA. However, given the similar risks of SICH and mortality, IV-tPA in the late time window could be considered in patients with both PS and DM.

A Rare Case of Breast Cancer Metastasis to the Optic Nerve Head

Purpose@#To report a case of metastatic breast cancer to the optic nerve with a favorable response to an increased dose of intravitreal bevacizumab injection.Case summary: A 60-year-old female presented to our clinic with blurred vision in her left eye for 3 weeks. The patient had a history of intraductal breast cancer carcinoma, metastasized to the mediastinum lymph nodes, liver, and bone and had received palliative chemotherapy and radiotherapy for 16 months. At her first presentation, best-corrected visual acuity of the left eye was 20/50 and the intraocular pressure was 11 mmHg. A yellowish elevated mass with hemorrhage at the optic disc with peripapillary swelling was observed in the left eye. Fluid at the subperipapillary and subfoveal areas and choroidal thickening with folds were observed with optic coherence tomography. The patient was diagnosed as having breast cancer metastasis to the optic nerve head. Three monthly intravitreal bevacizumab injections (0.05 mL, 1.25 mg) were administered, but showed limited effect. Two more intravitreal bevacizumab injections having twice the concentration of the previous dose (0.1 mL, 2.50 mg) were given. Tumor infiltration of the optic nerve head decreased, and serous retinal detachment subsided. No malignant cancer cells were detected in the anterior chamber. @*Conclusions@#We report a rare case of breast cancer metastasis to the optic nerve. Administering intravitreal bevacizumab injections with twice the dosage concentration could be an alternative treatment option, to alleviate exudative retinal detachment associated with metastatic tumor progression to the optic nerve head.

Successful Removal of a Difficult Common Bile Duct Stone by Percutaneous Transcholecystic Cholangioscopy

Common bile duct (CBD) stones are prevalent in 11% to 21% of patients with gallstones and can cause various clinical manifestations, from biliary colic to biliary sepsis. The treatment of choice is endoscopic retrograde cholangiopancreatography, but approximately 5% to 10% of CBD stones are difficult to remove using these conventional endoscopic methods. Although percutaneous transhepatic cholangioscopy and lithotripsy can be used as an alternative, it can be technically demanding and risky if the intrahepatic duct is not dilated. We report a case of a large CBD stone that was successfully removed using percutaneous transcholecystic cholangioscopy.

Association between Serum Insulin-Like Growth Factor-1and Neurological Severity in Acute Ischemic Stroke

Background@#and Purpose Serum insulin-like growth factor-1 (IGF-1) is known to have a neuroprotective effect. This study aimed to determine the effects of serum IGF-1 on the severity and clinical outcome of acute ischemic stroke (AIS). @*Methods@#This study included 446 patients with AIS who were admitted to Hallym University Sacred Heart Hospital within 7 days of stroke onset from February 2014 to June 2017. Serum IGF-1 levels were measured within 24 hours of admission. Stroke severity was measured using the National Institutes of Health Stroke Scale (NIHSS) score at admission, and the functional outcome at 3 months after symptom onset was assessed using the modified Rankin Scale score. The effects of serum IGF-1 levels on stroke severity and 3-month functional outcomes were analyzed using multivariate logistic regression analysis. @*Results@#This study evaluated 379 patients with AIS (age 67.2±12.6 years, mean±standard deviation; 59.9% males) after excluding 67 patients who had a history of previous stroke (n=25) or were lost to follow-up at 3 months (n=42). After adjusting for clinically relevant covariates, a higher serum IGF-1 level was associated with a lower NIHSS score at admission (adjusted odds ratio=0.44, 95% confidence interval=0.24–0.80, p=0.01), while there was no significant association at 3 months. @*Conclusions@#This study showed that a higher serum IGF-1 level is associated with a lower NIHSS score at admission but not at 3 months. Further studies are required to clarify the usefulness of the serum IGF-1 level as a prognostic marker for ischemic stroke.

Strabismus Surgical Outcomes in Patients with Tonic and Accommodative Convergence Excess Esotropia

PURPOSE: To investigate the surgical outcomes of augmented bilateral medial rectus (BMR) recession in patients with low accommodative convergence/accommodation (AC/A) ratio tonic convergence excess esotropia (ET) compared to high AC/A ratio convergence excess ET. METHODS: This study included patients with esodeviation ≥10 prism diopter at near than at distance fixation who underwent BMR recession. The medical records of all esotropic patients with convergence excess who underwent strabismus surgery were reviewed. Six patients with tonic convergence excess and 10 patients with a high AC/A ratio met the study inclusion criteria. A successful outcome was defined as a near or distance angle of deviation ≤8 prism diopter and a ≤10 prism diopter difference between the two at the final recorded visit. RESULTS: The mean age at surgery was 5.9 ± 1.6 years in the tonic convergence excess ET group and 7.3 ± 2.9 years in the high AC/A ET group (p = 0.301). The average length of the postoperative follow-up was 2.7 years (range, 0.6–8.4 years) in the tonic convergence excess ET group and 4.0 years (range, 0.6–8.4 years) in the high AC/A ET group (p = 0.426). Near-distance disparities were reduced in all patients with tonic convergence excess ET within 10 prism diopter postoperatively, but in only 6 of 10 patients in the high AC/A ET group. Five of 6 patients (83.3%) had successful outcomes in tonic convergence excess ET group; 5 of 10 patients (50%) had successful outcomes in the high AC/A ET group. CONCLUSIONS: In our series, five patients (83%) obtained successful results in the tonic convergence excess ET group compared with 50% in the high AC/A ET group. Augmented BMR recession can be safely performed in esotropic patients with tonic convergence excess.

A Case of Fungal Endophthalmitis after Having Received Extraction of Wisdom Tooth in Healthy Woman

PURPOSE: To report a case of candida endogenous endophthalmitis in healthy women who had received extraction of wisdom tooth. CASE SUMMARY: A 65-year-old medically healthy woman who had received extraction of wisdom tooth two weeks ago, presented with floater symptoms in her left eye. Best-corrected visual acuity was 20/40 and intraocular pressure was 17 mmHg in her left eye. Inflammatory cells were found in the anterior chamber and vitreous. Fluorescein angiography showed multiple hypofluorescence without vascular leakage. With provisional diagnosis of intermediate uveitis, she was prescribed oral steroid for two weeks. After that, inflammatory cells in anterior chamber was reduced but vitreous imflammatory cell was increased and fundus examination detected newly developed infiltrated lesion at superotemporal area. The patient was presumed to have fungal endophthalmitis and immediate intravitreal voriconazole injection was performed. Three days after intravitreal voriconazole injection, diagnostic vitrectomy and intravitreal voriconazole injection were performed. Vitreous cultures revealed the growth of Candida albicans. Despite the treatment, inflammatory response in anterior chamber and vitreous rapidly increased and visual acuity was decreased to hand movement. We changed anti-fungal agent, voriconazole to Amphotericin B. Additional three-time intravitreal injection was done and therapeutic vitrectomy with oil injection were performed. After treatment, the patient's fundus markedly improved and inflammatory response was decreased. CONCLUSIONS: This case report shows candida endophthalmitis in healthy woman who had received extraction of wisdom tooth. So to diagnose endophthalmitis, patient's medical history should carefully be checked including dental care history who presented with vitreous inflammation and inflammatory infiltrated lesion at fundus.
