We reported a 43-year-old male patient who presented with headache and diplopia. The cerebrospinal fluid analysis showed pleocytosis, suggesting acute meningitis. The subsequent polymerase chain reaction and genetic sequencing of blood and cerebrospinal fluid showed that the causative organism was Anaplasma phagocytophilum. This case suggests that we should consider anaplasmosis as a causative agent of acute meningitis; if an unexplained meningitis patient shows no response to any treatments.

Background/Aims:
Hyaluronic acid (HA) regulates cell adhesion, migration and proliferation in various cancers. The clinical implications of HA in resected head and neck squamous cell carcinoma have not been elucidated. We investigated the clinical significance and prognostic value of the expression of tumoral and stromal HA and its related proteins in oropharyngeal and oral cavity cancer.
Methods:
Resected tissues from oropharyngeal or oral cavity cancer patients undergoing surgery were analysed in tissue microarrays divided into stroma and cancer panels. The expression levels of HA, HA synthases and hyaluronidases were also assessed by immunohistochemistry.
Results:
A total of 160 resected oropharyngeal or oral cavity cancer tissues were analysed. Stromal HA expression was observed more frequently in human papilloma virus (HPV)-negative tumors, but other clinicopathological characteristics did not differ. In patients with HPV-negative oral cavity cancers, high stromal HA expression was associated with significantly shorter recurrence-free survival and overall survival compared with low stromal HA expression. The expression of HA in both tumors and stroma was significantly correlated with poorer outcomes than other combinations in patients with HPV-negative oral cavity cancers. However, these prognostic roles of HA were not observed in patients with HPV-negative oropharyngeal cancers. In the HPV-stratified multivariate analysis, high stromal HA expression remained an independent indicator of poor prognosis in terms of recurrence-free survival.
Conclusions
High stromal HA and expression of HA in both tumors and stroma were correlated with poor prognosis in HPV-negative oral cavity cancer, but not in HPV-negative oropharyngeal cancers.

Quarantine often provokes negative psychological consequences. Thus, we aimed to identify the psychological and behavioral responses and stressors of caregivers quarantined with young patients after a close contact to a coronavirus disease 2019 case at a children's hospital. More than 90% of the caregivers reported feelings of worry and nervousness, while some of them reported suicidal ideations (4.2%), and/or homicidal ideations (1.4%). Fear of infection of the patient (91.7%) and/or oneself (86.1%) were most frequently reported stressors. A multidisciplinary team including infection control team, pediatrician, psychiatrist, nursing staff and legal department provided supplies and services to reduce caregiver's psychological distress. Psychotropic medication was needed in five (6.9%), one of whom was admitted to the psychiatry department due to suicidality. Quarantine at a children's hospital makes notable psychological impacts on the caregivers and a multidisciplinary approach is required.

PURPOSE: The purpose of this study was to prospectively validate the Korean Cancer Study Group Geriatric Score (KG)-7, a novel geriatric screening tool, in older patients with advanced cancer planned to undergo first-line palliative chemotherapy. MATERIALS AND METHODS: Participants answered the KG-7 questionnaire before undergoing geriatric assessment (GA) and first-line palliative chemotherapy. The performance of KG-7 was evaluated by calculating the sensitivity (SE), specificity (SP), positive and negative predictive value (PPV and NPV), balanced accuracy (BA), and area under the curve (AUC). RESULTS: The baseline GA and KG-7 results were collected from 301 patients. The median age was 75 years (range, 70 to 93 years). Abnormal GA was documented in 222 patients (73.8%). Based on the ≤ 5 cut-off value of KG-7 for abnormal GA, abnormal KG-7 score was shown in 200 patients (66.4%). KG-7 showed SE, SP, PPV, NPV, and BA of 75.7%, 59.7%, 84.4%, 46.0%, and 67.7%, respectively; AUC was 0.745 (95% confidence interval, 0.687 to 0.803). Furthermore, patients with higher KG-7 scores showed significantly longer survival (p=0.006). CONCLUSION: KG-7 appears to be adequate in identifying patients with abnormal GA prospectively. Hence, KG-7 can be a useful screening tool for Asian countries with limited resources and high patient volume.

BACKGROUND AND PURPOSE: To investigate whether appointing a full-time neurointensivist to manage a closed-type neurological intensive care unit (NRICU) improves the quality of critical care and patient outcomes. METHODS: This study included patients admitted to the NRICU at a university hospital in Seoul, Korea. Two time periods were defined according to the presence of a neurointensivist in the preexisting open-type NRICU: the before and after periods. Hospital medical records were queried and compared between these two time periods, as were the biannual satisfaction survey results for the families of patients. RESULTS: Of the 15,210 patients in the neurology department, 2,199 were admitted to the NRICU (n=995 and 1,204 during the before and after periods, respectively; p<0.001). The length of stay was shorter during the after than during the before period in both the NRICU (3 vs. 4 days; p<0.001) and the hospital overall (12.5 vs. 14.0 days; p<0.001). Neurological consultations (2,070 vs. 3,097; p<0.001) and intrahospital transfers from general intensive care units to the NRICU (21 vs. 40; p=0.111) increased from the before to after the period. The mean satisfaction scores of the families of the patients also increased, from 78.3 to 89.7. In a Cox proportional hazards model, appointing a neurointensivist did not result in a statistically significant change in 6-month mortality (hazard ratio, 0.82; 95% confidence interval, 0.652–1.031; p=0.089). CONCLUSIONS: Appointing a full-time neurointensivist to manage a closed-type NRICU had beneficial effects on quality indicators and patient outcomes.

BACKGROUND: Complete blood count (CBC) results play an important role in peripheral blood smear (PBS) examinations. Many descriptions in PBS reports may simply be translated from CBC parameters. We developed a computer program that automatically generates a PBS draft report based on CBC parameters and age- and sex-matched reference ranges. METHODS: The Java programming language was used to develop a computer program that supports a graphical user interface. Four hematology analyzers from three different laboratories were tested: Sysmex XE-5000 (Sysmex, Kobe, Japan), Sysmex XN-9000 (Sysmex), DxH800 (Beckman Coulter, Brea, CA, USA), and ADVIA 2120i (Siemens Healthcare Diagnostics, Eschborn, Germany). Input data files containing 862 CBC results were generated from hematology analyzers, middlewares, or laboratory information systems. The draft reports were compared with the content of input data files. RESULTS: We developed a computer program that reads CBC results from a data file and automatically writes a draft PBS report. Age- and sex-matched reference ranges can be automatically applied. After examining PBS, users can modify the draft report based on microscopic findings. Recommendations such as suggestions for further evaluations are also provided based on morphological findings, and they can be modified by users. The program was compatible with all four hematology analyzers tested. CONCLUSIONS: Our program is expected to reduce the time required to manually incorporate CBC results into PBS reports. Systematic inclusion of CBC results could help improve the reliability and sensitivity of PBS examinations.

Superficial siderosis results from the deposition of hemosiderin in subpial layers of the central nervous system following hemorrhage in subarachnoid spaces. Infratentorial superficial siderosis (ISS) presents with unique clinical features including progressive hearing loss, ataxia, and myelopathy, and the most common cause of idiopathic ISS is dural abnormality. Here we report a case of idiopathic ISS with radiological findings of spontaneous intracranial hypotension, whose clinical symptoms of ISS including cerebellar dysfunction improved after supine position was maintained for 2 months.

Neovascular glaucoma is a subtype of secondary glaucoma that is characterized by proliferation of fibrovascular tissue in the anterior chamber angle. This condition may be acutely aggravated by carotid revascularization therapies. There have been few previous reports of acute aggravation of neovascular glaucoma following carotid artery stenting. We report the case history of a patient who had acute exacerbation of neovascular glaucoma following carotid artery stenting and required surgical management.

Knee pain is rarely an initial symptom of colon cancer, because most bone metastases develop in the late stage of cancer. Therefore, patients with colorectal cancer usually present with gastrointestinal symptoms. Recently, we experienced a 46-year-old female with rectal cancer that presented as knee pain due to tibial metastasis without other organ metastasis. She was evaluated for knee pain and diagnosed with a rectal cancer after biopsies of the tibial and rectal masses. We report the first such case in Korea with a review of the literature.
