BACKGROUND: Several antibiotics can be used to treat ventilator-associated pneumonia caused by carbapenem-resistant A. baumannii (CRAB-VAP) including high-dose sulbactam. However, the effectiveness of high-dose sulbactam therapy is not well known. We report our experience with high-dose sulbactam for treatment of CRAB-VAP. METHODS: Medical records of patients with CRAB-VAP who were given high-dose sulbactam between May 2013 and June 2015 were reviewed. RESULTS: Fifty-eight patients with CRAB-VAP were treated with high-dose sulbactam. The mean age was 72.0 ± 15.2 years, and the acute physiology and chronic health evaluation II (APACHE II) score was 15.1 ± 5.10 at the time of CRAB-VAP diagnosis. Early clinical improvement was observed in 65.5% of patients, and 30-day mortality was 29.3%. Early clinical failure (odds ratio [OR]: 8.720, confidence interval [CI]: 1.346-56.484; p = 0.023) and APACHE II score ≥ 14 at CRAB-VAP diagnosis (OR: 10.934, CI: 1.047-114.148; p = 0.046) were associated with 30-day mortality. CONCLUSIONS: High-dose sulbactam therapy may be effective for the treatment of CRAB-VAP. However, early clinical failure was observed in 35% of patients and was associated with poor outcome.

A 5-month-old male infantshowed greasy sealy papules on the scalp, dirty scaly papules on the trunk and scaly petechial papules on both the palms and soles since birth. When admitted to the hospital, the patient exhibited lymphadenopathy, hepatomegaly, abdominal distension, mild fever and skin eruption. The biopsy specimens from the skin and lymph node showed an infiltrate composed almost entirely of histiocytic cells with irregularly shaped nuclei and abundant, well demarcated cytoplasm. The histiocytic cells of the infiltrate were proved as Langerhans cells by electron microscopic examination and S-100 protein study. He was treated with methotrexate 30mg/m twice a week and prednisolone 40mg/m daily. Initially skin lesions and general condition were improved, but the patient expired. due to septicemia after 3 months.

Hemorrhagic fever with renal syndrome (HFRS) in Korea is caused by 2 serotypes of hantavirus, Hantaan and Seoul. Even though the number of peripheral CD8' T-lymphocytes is markedly elevated in the acute phase of HFRS, the pathogenetic role of this phenomena is not clear. To elucidate the role of cell-mediated immune response in HFRS, we measured concentrations of cytokines, such as IL-1, IL-2, IL-4, IL-6, IL-10 and IFN-r in plasma samples obtained from 15 patients (15 men, 20-24 years old) at various phase of illness. Cytokines were measured by ELISA in plasma samples. The plasma concentration of IL-10 was elevated in 13/15 patients. The median maximum value, during days 4-8, was 23 ng/L (range, 0-70.2). The maximum values were significantly higher(p=0.005) than the baseline. IL-1 and IL-6 was detected in 6 patients. Other cytokine responses (IL-2, IL-4, IFN-r ) were negligible. There was no significant correlation between maximum levels of IL-10 and maximum serum concentration of creatinine (r=0.118, p=0.675), and lowest plate#let count (r=-0.088, p=0.765). Kinetics of IL-10 were quite similar in HFRS patients with maximum creatinine values >3 mg/dL and in those with values <3 mg/dL. In conclusion, plasma IL-10 levels, but not IL-2, IL-4 or INF-r were elevated in acute phase of HFRS, and it suggests that the systemic immunosuppressive activities of IL-10 might have some pathogenetic role in HFRS.

Renal epithelial cells damaged by ischemia/reperfusion (I/R) can be restored by timely and appropriate treatment. Recent studies have reported that intra renal adult kidney stem cells contribute to the restoration of tubules damaged by I/R. Here, we determined the role of adult tubular cells in the restoration of damaged tubules. We labeled slow cell-cycle cells (SCCs) with 5-bromo-2'-deoxyuridine (BrdU) and investigated their location in the kidneys as well as their contribution to the restoration of tubular cells damaged by I/R injury in mice. Thirty minutes of bilateral ischemia resulted in severe disruption of tubular epithelial cells along with a decline in renal function. The post-ischemic disruption of tubular epithelial cells was most severe in the S3 segment of the outer stripe of the outer medulla. Damaged tubules demonstrated gradual recovery of renal function over time. BrdU-labeled SCCs were mainly observed in tubules located at the junction of cortex and outer medulla, as well as in the inner medulla. The tubular SCCs expressed functional tubule cell markers such as Na/K-ATPase, Na-K-Cl cotransporter-2, and aquaporin 1 and 2. BrdU-labeled SCCs survived I/R injury and proliferated. These results demonstrate that SCCs present in tubules contribute to the restoration of tubular epithelial cells injured by I/R.

OBJECTIVES: Previous studies have suggested that some personality characteristics are associated with the onset, prognosis and social function in schizophrenia patients. However few is known about the personality and affective characteristic of genetic high risk group (GHR) for schizophrenia. This study aimed to investigate the personality and the affective characteristic of GHR group for schizophrenia. METHODS: Participants were 54 healthy controls (HC), 26 subjects with GHR for schizophrenia and 28 subjects with first episode psychosis (FEP). We performed three self-report questionnaires; NEO-Personality Inventory-Revised, State and Anger Expression Inventory and Positive Affect and Negative Affect Schedule. RESULTS: The GHR group showed higher score in agreeableness item than the HC (p=0.028). In extraversion item, the FEP group showed significantly lower scores than the HC (p=0.001). The GHR group showed lower scores in neuroticism item compared with FEP group in trend level. The FEP group showed higher trait-anger, lower positive affect and higher negative affect compared with the others. CONCLUSION: The GHR group seem to share certain vulnerable personality and affective characteristics for schizophrenia with the FEP group. On the other hands, the GHR group appeared to be more agreeable than the other groups, which might act as the compensation for other impaired functions.

Schwannoma is an encapsulated nerve sheath tumor that is distinct from neurofibromatosis. It is defined as the occurrence of multiple schwannomas without any bilateral vestibular schwannomas. A 46-year-old man with multiple schwannomas involving peripheral nerves of the ipsilateral lower extremity presented with neurologic symptoms. Electrodiagnostic studies revealed multiple mononeuropathies involving the left sciatic, common peroneal, tibial, femoral and superior gluteal nerves. Histologic findings confirmed the diagnosis of schwannoma. We reported this rare case of segmental schwannomatosis that presented with neurologic symptoms including motor weakness, which was confirmed as multiple mononeuropathies by electrodiagnostic studies.

Background:
Swallowing function deterioration is a common problem experienced by older adults worldwide. Many studies have been conducted to improve swallowing function in older adults; however, due to differences in intervention methods and study designs, it is difficult to draw a common conclusion. This study aimed to analyze trends and intervention methods in studies of swallowing function intervention for older adults conducted from 2010 to 2022, to establish a systematic approach for developing interventions to improve swallowing function in older adults and to provide evidence for this approach.
Methods:
Literature research was conducted for studies published between 2010 and 2022 that applied to swallow function interventions to adults aged 60 years or older. Databases including PubMed, Medline, RISS, Science On, KISS, and KCI were used. From a total of 1,164 articles searched using keywords, 20 articles were selected for final analysis.
Results:
The number of published articles steadily increased over time, and the intervention period was most commonly 6 or 8 weeks. The types of interventions included focused exercises to improve oral muscle strength in 12 articles and programs incorporating education, practice, and expert management in 8 articles. Among the focused exercises, tongue-strengthening exercises were most common in 4 articles. The evaluation variables for intervention effects were muscle strength evaluation, oral function evaluation, quality of life, and oral health and hygiene status. Muscle strength and oral function evaluations were statistically significant in focused exercise interventions, while the quality of life and oral health and hygiene status was significant in program interventions.
Conclusion
This literature review is meaningful as a study that can be used to select the intervention period and program contents when planning an elderly swallowing intervention program.

OBJECTIVE: Executive dysfunction might be an important determinant for response to pharmacotherapy in obsessive-compulsive disorder (OCD), and could be sustained independently of symptom relief. The anterior cingulate cortex (ACC) has been indicated as a potential neural correlate of executive functioning in OCD. The present study examined the brain-executive function relationships in OCD from the ACC-based resting state functional connectivity networks (rs-FCNs), which reflect information processing mechanisms during task performance. METHODS: For a total of 58 subjects [OCD, n=24; healthy controls (HCs), n=34], four subdomains of executive functioning were measured using the Rey-Osterrieth Complex Figure Test (RCFT), the Stroop Color-Word Test (SCWT), the Wisconsin Card Sorting Test (WCST), and the Trail Making Test part B (TMT-B). To probe for differential patterns of the brain-cognition relationship in OCD compared to HC, the ACC-centered rs-FCN were calculated using five seed regions systemically placed throughout the ACC. RESULTS: Significant differences between the OCD group and the HCs with respect to the WCST perseverative errors, SCWT interference scores, and TMT-B reaction times (p<0.05) were observed. Moreover, significant interactions between diagnosis×dorsal ACC [S3]-based rs-FCN strength in the right dorsolateral prefrontal cortex for RCFT organization summary scores as well as between diagnosis×perigenual ACC [S7]-based rs-FCN strength in the left frontal eye field for SCWT color-word interference scores were unveiled. CONCLUSION: These network-based neural foundations for executive dysfunction in OCD could become a potential target of future treatment, which could improve global domains of functioning broader than symptomatic relief.
