RESUMEN
Isolated unilateral hypoglossal nerve palsy (IUHNP) is rare because of its complex course and close adjacent structures. Prostate cancer is a very rare cause of hypoglossal nerve palsy and reported scarcely. We herein report the first case of metastatic prostate cancer presented with IUHNP in Korea, which shows good clinico-radiological correlation.
RESUMEN
Objective@#Resuscitation-related gastric inflation is associated with inadequate ventilation and the risk of gastric regurgitation in out-of-hospital cardiac arrest (OHCA) patients. This study aims to estimate resuscitation-related gastric inflation values by using multi-detector computed tomography (MDCT) scanning. @*Methods@#MDCT imaging data were obtained from OHCA patients undergoing resuscitation from January 2014 to December 2020. Thirty age- and sex-matched healthy controls that underwent an MDCT scan were included. Gastric air volume (GAV), total gastric volume (TGV), and GAV/gastric content volume (GCV) ratio values were estimated. @*Results@#In healthy controls (n=30), GAV and TGV values were in the range 5.0-35.0 mL, and 202.0-1,002.0 mL, respectively. The mean GAV and TGV values of OHCA patients (n=97) were 251.0 mL (range, 55.5-896.0) and 878.0 mL (range, 430.5-1,696.0), respectively. Significant between-group differences were determined in the mean GCV, GAV, and GAV/GCV ratio values. In OHCA patients, the cut-off value for abnormal GAV was defined as 56.5 mL (mean value plus two times standard deviation). Patients with abnormal GAV findings on MDCT scans had a longer duration from arrest to the return of spontaneous circulation, low body mass index, and increased rates of lactic acidosis. @*Conclusion@#Our results indicate an association between gastric air accumulation after resuscitation with longer recovery from arrest to return of spontaneous circulation, low body mass index, and increased lactic acidosis.
RESUMEN
Objectives@#Given that cardiopulmonary resuscitation (CPR) is an aerosol-generating procedure, it is necessary to use a mechanical ventilator and reduce the number of providers involved in resuscitation for in-hospital cardiac arrest in coronavirus disease (COVID-19) patients or suspected COVID-19 patients. However, no study assessed the effect of changes in inspiratory time on flowrate and airway pressure during CPR. We herein aimed to determine changes in these parameters during CPR and identify appropriate ventilator management for adults during CPR. @*Methods@#We measured changes in tidal volume (Vt), peak inspiratory flow rate (PIFR), peak airway pressure (Ppeak), mean airway pressure (Pmean) according to changes in inspiratory time (0.75 s, 1.0 s and 1.5 s) with or without CPR. Vt of 500 mL was supplied (flowrate: 10 times/min) using a mechanical ventilator. Chest compressions were maintained at constant compression depth (53 ± 2 mm) and speed (102 ± 2/min) using a mechanical chest compression device. @*Results@#Median levels of respiratory physiological parameters during CPR were significantly different according to the inspiratory time (0.75 s vs. 1.5 s): PIFR (80.8 [73.3 – 87.325] vs. 70.5 [67 – 72.4] L/min, P < 0.001), Ppeak (54 [48 – 59] vs. 47 [45 – 49] cmH2O, P < 0.001), and Pmean (3.9 [3.6 – 4.1] vs. 5.7 [5.6 – 5.8] cmH2O, P < 0.001). @*Conclusions@#Changes in PIFR, Ppeak, and Pmean were associated with inspiratory time. PIFR and Ppeak values tended to decrease with increase in inspiratory time, while Pmean showed a contrasting trend. Increased inspiratory time in low-compliance cardiac arrest patients will help in reducing lung injury during adult CPR.
RESUMEN
Background@#and Purpose Nonconvulsive status epilepticus (NCSE) is challenging to diagnose. This study aimed to describe and classify the clinical features and electroencephalography (EEG) findings of patients with de novo NCSE and to correlate them with clinical outcomes. @*Methods@#We retrospectively reviewed the medical and EEG records of patients admitted to our institution with altered mentation and EEG abnormalities from January 1, 2013 to December 31, 2018. We evaluated premorbid modified Rankin Scale (mRS) scores, underlying disorders, precipitating factors, clinical manifestations, laboratory tests, and outcomes after a 3-month follow-up. Patients who met the Salzburg Consensus Criteria for NCSE were categorized into good-outcome and poor-outcome groups. A good outcome was defined as 1) clinical and electrographic seizures ceasing after treatment, and 2) an mRS score of ≤2 or remaining unchanged during the 3-month follow-up. A poor outcome was defined as 1) death, 2) seizures continuing despite treatment, or 3) a follow-up mRS score of ≥3 in a patient with a premorbid mRS score of ≤2, or a follow-up mRS score that increased in a patient with a premorbid mRS score of ≥3. @*Results@#The 48 included patients comprised 37 categorized into the good-outcome group and 11 into the poor-outcome group. The presence of acute metabolic disturbances was significantly correlated with poor outcome (p=0.036), while the other analyzed variables were not significantly correlated with outcomes. @*Conclusions@#Acute metabolic disturbances in NCSE are associated with poor outcomes. Adequate treatment of underlying reversible disorders alongside controlling seizures is critical for patients with NCSE.
RESUMEN
Background@#The median-to-ulnar comparison test (MUCT), and increasingly, ultrasonography (US) are considered as complementary to and more sensitive than median nerve conduction study (NCS) in diagnosing carpal tunnel syndrome (CTS). @*Methods@#In consecutive patients with hand paresthesia compatible with CTS but with normal median NCS, we additionally performed the MUCT and analyzed whether it yielded better diagnostic sensitivity. @*Results@#In total, 163 hands of clinically diagnosed CTS patients were examined with routine NCS. The MUCT and US were performed in 81 hands and 31 hands, respectively. While median NCS was diagnostic in 85 (52.1%) hands, MUCT failed to demonstrate superior sensitivity over median NCS in the other hands and US revealed related abnormalities better than both routine NCS (p=0.006) and MUCT (p=0.002). @*Conclusions@#The MUCT offered no additional diagnostic benefit. On the other hand, sonographic examination had higher sensitivity for the diagnosis of CTS when applying several diagnostic criteria. Thus, US could be the screening test for diagnosing CTS prior to NCS with higher sensitivity than MUCT. However, further studies are needed to define the appropriate diagnostic criteria for US.

RESUMEN
Metabolic encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome is characterized by encephalopathy mimicking acute stroke, which is rarely observed in adulthood. We present a case of a female who presented with several neurologic deficits and diagnosed with MELAS syndrome. Brain magnetic resonance imaging (MRI) showed acute lesions mimicking stroke, which were not compatible with specific vascular territories. Magnetic resonance spectroscopy showed lactate peaks in both symptomatic and asymptomatic area. Single proton emission computed tomography (SPECT) shows hyperperfusion in the same area. On follow-up image, MRI lesion nearly disappeared and hyperperfusion on SPECT changed into hypoperfusion. We discuss the clinical characteristics and image findings of our patient.
RESUMEN
BACKGROUND: The decreased estimated glomerular filtration rate (eGFR) levels at admission in patients with stroke have been associated with more severe clinical deficits and with worse outcomes; however, the relationship between eGFR levels and volumetric measurement of cerebral infarct size on neuroimaging has not been studied, to our knowledge. METHODS: Consecutive patients who presented within 48h of ischemic stroke and underwent brain diffusion-weighted imaging (DWI) over a 55-month period were studied. Patients with ischemic stroke of large artery atherosclerosis (LAA), small vessel occlusion (SVO), or cardioembolism (CE) etiologies were included. Those who were treated with thrombolysis and disabled before index stroke were excluded. Infarction volumes were log transformed to approximate normality. Chronic kidney disease (CKD) was defined as an eGFR < 60 mL/min per 1.73 m2. Subjects were categorized into two groups: CKD or no CKD. The relationship between CKD and DWI infarct volumes was examined using an analysis of covariance. RESULTS: Of the included 405 patients (mean age, 68 years; female, 60.2%; LAA, 60.0%; SVO, 16.5%; CE, 23.5%), 108 patients had CKD. Infarct volumes (mL, median [interquartile range]) were not significantly different between stroke patients with CKD and those without CKD in any stroke subtype (LAA, 0.77 [0.01-2.97] vs. 0.96 [0.01-5.22]; SVO, 0.18 [0.02-0.21] vs. 0.27 [0.01-0.52]; CE, 8.91 [0.04-28.54] vs. 5.22 [0.05-42.39]). Adjustment for possible confounders did not change the associations. CONCLUSIONS: Renal impairment is not associated with cerebral infarct volume among acute ischemic stroke patients.

Hypertensive brainstem encephalopathy is a rare variant of hypertensive encephalopathy. A 54-year-old female with chronic kidney disease visited our hospital because of comatose mentality. Her blood pressure was 256/206 mmHg. Magnetic resonance imaging revealed multifocal vasogenic edema in the brainstem, cerebellum, and bilateral cerebral cortical, subcortical, and deep nuclear areas. Her symptoms and radiological lesions improved when the blood pressure was decreased. This case demonstrates that these extensive lesions can be associated with an acute hypertensive crisis.

Ceftazidime is a widely used third-generation cephalosporin. We report a case of ceftazidime-induced nonconvulsive status epilepticus in a patient with renal failure. A 56-year-old man experienced the gradual development of altered mentation after a diabetic foot ulcer was treated with ceftazidime. Rhythmic sharply contoured triphasic waves were evident in all electroencephalography leads. The clinical and electrographical seizures ceased after introducing antiepileptic drugs and discontinuing ceftazidime. This case demonstrates that altered mentality and nonconvulsive status epilepticus can be caused by ceftazidime in patients with renal dysfunction.

PURPOSE: To report a case of Pseudomonas fluorescens infection following endoscopic dacryocystorhinostomy and silicone tube intubation in a healthy patient who was using steroid nasal spray. In addition, a literature review is conducted. CASE SUMMARY: A 72-year-old female patient came to our clinic with tearing and hyperemia in the right eye. Ten months prior, she had undergone endoscopic dacryocystorhinostomy and silicone tube intubation due to nasolacrimal duct obstruction in the right eye. Six months after the first operation, dacryocystorhinostomy revision with silicone tube exchange was performed due to obstruction of the nasal bony orifice. In addition, the patient was using a steroid nasal spray. On slit lamp examination, conjunctival injection, marked inflammation and punctal edema around the tube were observed. The silicone tube was removed and the tube cultured. Pseudomonas fluorescens was isolated from the tube contents. The patients was treated with topical 0.3% gatifloxacin 4 times a day, methylol cephalexin lysinate 1000 mg 3 times a day and the nasal spray was discontinued. Two weeks later, all symptoms were resolved after treatment with antibiotic treatment. CONCLUSIONS: A case of Pseudomonas fluorescens canaliculitis which occurred in healthy patient who was using steroid nasal spray is presented with a literature review. Pseudomonas fluorescens canaliculitis can be treated by using proper antibiotics.

Palinopsia means a visual image persisting for minutes to hours or reappearing episodically after the exciting stimulus has been removed. The anatomic correlation of palinopsia is not clear, whereas occipito-parietal and occipito-temporal lesions have been implicated. We describe a patient presenting palinopsia prior to motor seizures which was related to left posterior temporal lesion. A 36-year-old man had a generalized tonic clonic seizure after palinoptic positive visual afterimages. Brain MRI and Transfemoral cerebral angiography (TFCA) revealed an arteriovenous malformation of 1x1.5x2 cm3. We used oxcarbazepine for preventing recurrent seizures and planned gamma knife radiosurgery. Palinopsia is a very rare clinical manifestation as an aura of seizures. Palinopsia preceding clinical seizure as a localizing value, so that neuroimaging is mandatory in this clinical situation. This is the first reported case of palinopsia in Korea.

Epidermoid cysts are benign developmental anomalies that are rarely observed in the oral cavity of neonate. If large in size, especially in the developing fetus or newborn infant, they can cause swallowing difficulty and occasionally respiratory difficulty. We report a case of epidermoid cyst in the oral cavity detected prenatal sonography. The sonographic finding was large cystic mass, measuring 30x25 mm. In this case, supplies and equipment for an emergency tracheostomy were made available prior to the delivery. However, the infant did not require intervention to secure the airway. The lesion was surgically excised, and histologic diagnosis was epidermoid cyst. After 6 months of follow up, the cyst had not recurred. This case illustrates the value of accurate prenatal diagnosis and planned perinatal management using a team approach.

Anti-leucine-rich glioma inactivated-1 (LGI1) limbic encephalitis (LE) is a rare neurological disorder that has a subacute course of progressive encephalopathy and fasciobrachial dystonic seizures. We report a patient with anti-LGI1 LE that presented with atypical manifestations that complicated the diagnosis. A 62-year-old woman presented with a chronic course of memory disturbance and a subsequent relapse with an altered mental status after 10 months. The patient reported frequent chest pain of squeezing and dull nature, typically lasting 10-30 seconds. The chest pain was related to partial seizures, which were confirmed by video-EEG monitoring. Anti-LGI1 antibody was identified in serum and CSF. The patient's symptoms improved by immune modulation treatment. Patients with anti-LGI1 LE can experience atypical partial seizures, and a chronic relapsing course. Clinical suspicions and video-EEG monitoring are helpful for the early diagnosis and effective immune modulation.
