PURPOSE: To report a case of endogenous endophthalmitis due to Klebsiella ozaenae, which is a rare causative organism of endophthalmitis. CASE SUMMARY: A 61-year-old male who was undergoing chemotherapy for hepatocellular carcinoma complained of sudden visual loss and ocular pain in his left eye for 2 days. On the first examination, the patient's visual acuity was counting fingers at 10 cm and the intraocular pressure was elevated to 29 mm Hg. Partial scleral rupture and choroidal prolapse were observed. Subretinal abscess was detected with increased echogenicity using ultrasonography. The patient complained of burning sensation on voiding and urinary frequency; subsequent urinalysis showed pyuria and bacteriuria. Intravitreal and systemic antibiotics were administered under the impression of endogenous endophthalmitis caused by urinary tract infection. Despite treatment, visual acuity decreased to no light perception in 4 days and intraocular pressure and pain was uncontrollable. Enucleation was performed and pus culture from the eye during surgery revealed Klebsiella ozaenae. CONCLUSIONS: Klebsiella ozaenae is a rare causative organism of endophthalmitis and shows a rapid progress and poor prognosis. Endogenous endophthalmitis must be highly suspected in patients with urinary tract infection as well as pyogenic liver abscess.

PURPOSE: The authors experienced a case of orbital emphysema causing eye movement disorder following conjunctival tear without any orbital wall fractures after exposure to compressed air. CASE SUMMARY: A 28-year-old man's left periorbital area was injured while working with compressed air. There was marked lid swelling on the left side with palpable crepitus. The patient had an exotropia and hypertropia of the left eye. In addition, the extraocular movement of the left eye was restricted on upgaze without nausea and vomiting. On slit-lamp examination, conjunctival partial laceration and subconjunctival air bubbles adjacent to the conjunctival laceration could be seen. Orbital computed tomography showed air in the periorbital and retrobulbar region of the left eye and no evidence of orbital fracture. On examination 4 days after the primary repair of the conjunctival laceration, the patient completely recovered without any complication. CONCLUSIONS: Orbital emphysema following a conjunctival laceration caused by compressed air without any orbital wall fractures can cause restriction of eye movement.

Pyogenic sacroiliitis is a rare osteoarticular infection, occurring most frequently in children and young adults. Diagnosis of the disease is challenging because of a general lack of awareness of the disease and its nonspecific signs and symptoms. Staphylococcus aureus is the most common causative bacteria in pyogenic sacroiliitis. Methicillin-resistant S. aureus (MRSA) has typically been considered a hospital-associated pathogen; however, community-acquired (CA)-MRSA infections are becoming increasingly common in Korea. We report the first domestic case of acute pyogenic sacroiliitis with abscess and bacteremia caused by CA-MRSA. The pathogen carried the type IV-A staphylococcal cassette chromosome mec (SCCmec) without the Panton-Valentine leukocidin (PVL) gene, and was identified as sequence type (ST) 72 by multilocus sequence typing.

Background: Although electrocardiography and cardiac troponin play important roles in the diagnosis of acute coronary syndrome (ACS), there remain unmet clinical needs. Heart-type fatty acid-binding protein (H-FABP) has been identified as an early diagnostic marker of acute myocardial infarction (AMI). In this study, we examined the diagnostic and prognostic value of H-FABP in patients suspected with ACS. Methods: We conducted an observational single-center cohort study, including 89 adults aged 30 years or older, who presented to the emergency room (ER) within 24 hours after the onset of chest pain and/or dyspnea. We performed laboratory analysis and point-of-care testing (POCT) for cardiac markers, including H-FABP, troponin I, and creatine kinasemyocardial band. We also evaluated the correlation between cardiac markers and left ventricular (LV) dysfunction and extent of coronary artery disease (CAD). Results: In patients presented to ER within 4 hours after symptom onset (n = 49), the diagnostic accuracy of H-FABP for AMI, as quantified by the area under the receiver operating characteristic curve, was higher (0.738; 95% confidence interval [CI], 0.591–0.885) than other cardiac markers. In POCT, the diagnostic accuracy of H-FABP (56%; 95% CI, 45–67) was significantly higher than other cardiac markers. H-FABP was correlated with not extent of CAD but post-AMI LV dysfunction. Conclusion H-FABP is a useful cardiac marker for the early diagnosis of AMI and prediction of myocardia injury. Difference in the circulatory release timeline of cardiac markers could explain its utility in early-stage of myocardial injury.

Purpose: The purpose of this study is to develop and apply a neonatal supportive positioning (NSP) training video program for premature infants, using a position support mat for nurses in neonatal intensive care units (NICUs), and to verify its effect on nurses' performance. Methods: Thirty-five NICU nurses were included in the study. For the pre-test, preliminary check-ups were conducted, questionnaires about NSP knowledge on preterm infants were distributed, and NSP performance using neonatal dolls were video recorded for each participant. PowerPoint presentations and videos were used to educate participants on NSP. Furthermore, a 20-minute one-on-one training session was conducted using an NPS kit. Two weeks after the training, we repeated the process of distributing questionnaires about NSP knowledge and recording nurses’ performance videos using neonatal dolls. Questionnaires and videos collected before and after the training were compared. Results: After NSP training, the mean knowledge score of the participants improved significantly from 23.71 ± 3.62 to 29.51 ± 2.29 (Z = −5.09, p < .001). The performance score for postural supportive positioning was 38.03 ± 7.46 before training and 80.06 ± 9.85 after receiving training, indicating a high-performance score after NSP training (Z = −5.16, p < .001). Conclusion Our NSP training video program increased nurses’ NSP knowledge and performance. Continuous training NICU nurses on NSP, using a standardized training video program, can help improve the care of premature infants.
