Background: Mycoplasma pneumoniae is a major cause of community-acquired pneumonia (CAP) in children, with a rising incidence of macrolide resistance. Early diagnosis is crucial for reducing the disease burden; however, current diagnostic tools have limitations.We evaluated the diagnostic accuracy of serological assays and their performance based on symptom onset in children with CAP. Methods: From September 2023 to September 2024, we prospectively enrolled children with CAP, classified as M. pneumoniae pneumonia (MPP) or non-MPP, from 16 hospitals in Korea. Serological testing included chemiluminescence immunoassay (CLIA) and ELISA for detecting IgM and IgG, along with particle agglutination (PA) for total antibody measurements. Serological responses were analyzed at different times after symptom onset (0–4, 5–9, and 10–21 days). Results: Among 472 children with CAP (362 MPP, 110 non-MPP), 138 (29.2%) underwent PA testing, and 334 (70.8%) underwent IgM testing. PA at a 1:640 cutoff showed 48.0% sensitivity and 100% specificity. CLIA and ELISA showed comparable sensitivities (69.1% vs. 69.2%) and specificities (76.9% vs. 66.7%) for IgM testing. Seropositivity increased significantly with time since symptom onset (P for trend < 0.001), reaching 97.9% for IgM, 62.5% for IgG, and 94.7% for PA at 10–21 days. Conclusions The time post-symptom onset significantly influenced the diagnostic utility of serological tests for pediatric MPP, which showed limited value during the early stage of illness. These findings emphasize the importance of symptom onset-based interpretation of serological test results and their utility in complementing PCR when optimizing MPP diagnosis in children.

Background: Because the etiologies of bronchiectasis and related diseases vary significantly among different regions and ethnicities, this study aimed to develop a diagnostic bundle for bronchiectasis in South Korea. Methods: A modified Delphi method was used to develop expert consensus statements on a diagnostic bundle for bronchiectasis in South Korea. Initial statements proposed by a core panel, based on international bronchiectasis guidelines, were discussed in an online meeting and two email surveys by a panel of experts (≥70% agreement). Results: The study involved 21 expert participants, and 30 statements regarding a diagnostic bundle for bronchiectasis were classified as recommended, conditional, or not recommended. The consensus statements of the expert panel were as follows: A standardized diagnostic bundle is useful in clinical practice; diagnostic tests for specific diseases, including immunodeficiency and allergic bronchopulmonary aspergillosis, are necessary when clinically suspected; initial diagnostic tests, including sputum microbiology and spirometry, are essential in all patients with bronchiectasis, and patients suspected with rare causes such as primary ciliary dyskinesia should be referred to specialized centers. Conclusion Based on this Delphi survey, expert consensus statements were generated including specific diagnostic, laboratory, microbiological, and pulmonary function tests required to manage patients with bronchiectasis in South Korea.

Purpose: The purpose of this study was to compare differences in spiritual needs (SNs) and factors influencing SNs between patients with progressive terminal kidney disease and their family caregivers. Methods: An explorative comparative survey was used to identify the SNs of patients (N=102) with progressive terminal kidney disease undergoing hemodialysis and their family caregivers (N=88) at a general hospital located in Seoul, South Korea. The data were analyzed using descriptive statistics, the chi-square test, the independent t-test, one way analysis of variance, the Scheffé test, and multiple regression with dummy variables. Results: The SNs among family caregivers were higher than in the patient group. SNs were higher among those who were religious in both groups. Loving others was the highest-ranked subdimension in the patient group, followed in descending order by maintaining positive perspective, finding meaning, Reevaluating beliefs and life, asking “why?”, receiving love and spiritual support, preparing for death, and relating to God. In the family group, the corresponding order was maintaining positive perspective, loving others, finding meaning, receiving love and spiritual support, preparing for death, relating to God, and asking “why?”. The factors that had a negative influence on the level of SNs were not being religious in the patient group and having only a middle school level of education in the family group. Conclusion The results of this study may serve as evidence that spiritual care for non-cancer patients’ family caregivers should be considered as an important part of hospice and palliative care.

Purpose: This study aimed to describe the meaning of spiritual care as perceived by nursing students. Methods: This study used a descriptive research design, and the participants were 126 fourth-year nursing students from three nursing colleges. Data were collected from August to September 2019, and were analyzed using the content analysis method. Results: Four themes of spiritual care with 15 sub-themes were extracted from the content analysis: 1) “promoting spiritual well-being” (sub-themes: “providing religious help”, “caring for the patient as a spiritual being”, and “presupposing human dignity regardless of religion”); 2) “taking place in actual nursing practice” (representative sub-themes: “considering the perspective of the patient”, “reducing suffering”); 3) “caring for the multifaceted needs of human beings” (representative sub-themes: “providing physical, mental, and spiritual care”, “caring for both the mental and physical health of the patient”), and 4) “growing together”(sub-themes: “positively affecting patient well-being”, “beginning with the nurse’s self-transcendence”). Conclusion These results suggest that nursing students consider spiritual care to be a highly positive and practical form of nursing care. However, because few students have been exposed to religion and spirituality, more systematic training should be provided.

PURPOSE: To report a case of progressive outer retinal necrosis treated by combined intravitreal foscarnet and ganciclovir. CASE SUMMARY: A 11-year-old male with a history of chemotherapy and cord blood transplantation due to precursor T-cell leukemia developed Herpes zoster lesion on his forehead and rapidly progressing peripheral retinal necrosis without vasculitis in the right eye. Varicella-Zoster virus was confirmed in his cerebrospinal fluid using polymerase chain reaction (PCR); and the patient was diagnosed with progressive outer retinal necrosis. Despite combined treatment with intravenous acyclovir and foscarnet and intravitreal foscarnet, retinal necrosis progressed to retinal detachment and total retinal necrosis. During follow-up, new retinal necrosis was observed in his left eye. The patient was started on combined intravenous and intravitreal foscarnet and ganciclovir; retinal necrosis in the left eye regressed and posterior pole was spared. With subsequent oral valganciclovir and intravitreal foscarnet and ganciclovir, the remaining retina was preserved with maintained vision.

The increase in the prevalence of head injury amongst civilian population and the provision of adequate hospital services have become matters of world-wide concern. Many present-day accidents may result in the victims receiving multiple complex injuries beside head injuries and the prognosis may become unfavorable in these patients. Therefore, the neurosurgeon must be alert to the possibility that his patients have injuries to areas outside the brain and be capable of rendering necessary, often lifesaving, treatment during the initial phase of management. We analysed associated injuries in 1523 head injured patients admitted to Department of Neurosurgery, Kyung Hee University Hospital from October, 1971 till September, 1977. The results were as follows : 1) The incidence of associated injury was 23.6% of all 1523 head injured patients. 2) In all head injuries, male outnumbered female by almost 2 to 1 and the ratio was similar in associated injury group(2.4:1). 3) The age distribution of all head injuries was 3rd, 1st and 4th decases in order, but in associated injury group it was 4th, 3rd and 5th decades in order. 4) Common causes of head injuries were traffic accidents(76.6%) and fall(11.6%), but in associated injury group traffic accident was the most frequent cause(90.8%). 5) The incidence of associated injury was higher in relation to the severity of head injury. 6) The sites of associated injuries were distributed as limbs, chest and face in order and the most frequent nature of associated injuries was fracture. 7) Single associated injury was more frequent than multiple, associated injury, about 5 to 1. 8) Overall mortality rate of all head injuries was 9.3% in contrast that of associated injuries was 17.5%. 9) Surgical mortality rate was significantly higher in associated group(40.3%) than nonassociated group(26.1%). 10) In multiple associated injuries the mortality rate was higher(21.3%) than in single associated injury(16.4%). 11) Mortality rate according to associated injured sites was as follows ; 36% for visceral injuries and 34.1% for chest injuries. 12) The mortality rate was highest in serious chest injuries such as hemo and/or pneumothorax and in hypovolemic shock on admission(60%).

Arachnoid cysts are usually classified as developmental anomaly, inflammatory and traumatic in origin. Arachnoid cyst in posterior fossa occur frequently in the midline posterior to the cerebellum. These cyst usually present symptoms and signs due to increased intracranial pressure and may be confused with cerebellar or fourth ventricular tumor. Recently we had experienced a case of multiple retrocerebellar arachnoid cysts coexisted with pathologically confirmed desmoplastic medulloblastoma in eight months lod infant and reviewed the literatures.
