Computed tomography(CT) has enabled early recognition and treatment of focal injuries in patients with head trauma. However, CT has been less beneficial in identifying diffuse brain injury(DBI). The authors have analyzed retrospectively, a series of 132 patients with OBI observed for 2 years from Aug. 1986 to Jul. 1988 to evaluate the significance of the factors affecting outcome. Eighty-three patients were selected as being compatible with moderate and severe diffuse axonal injury(DAI) classified by Gennarelli, defined by coma without a CT lesion that is an obvious cause and coma greater than 24 hr with or without decerebration. The results are summarized as follows: 1) The 38(45.7%) out of 83 patients were found below age of 20, but there was no statistical significance between age distribution and outcome. 2) In case of initial Glasgow coma scale(GCS) of 7 or 8, 32(86.5%) out of 37 patients revealed good outcome, but 18(90%) of 20 patients with a score of 3 or 4 revealed poor outcome(p<0.01). 3) With regard to brain swelling in CT, there was significant statistical difference to outcome(p<0.05). 4) Small hemorrhages on corpus callosum, basal ganglia, basal cistern, peritentorial, lateral ventricle that is characteristic CT findings for DAI were showed 58(70%) out of all cases. It might be concluded that initial GCS, brain swelling and small hemorrhages in CT were significant factors affecting outcome in DAI.

Background:
The integrase strand transfer inhibitor dolutegravir has been indicated in Korea since 2014 for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in combination with other antiretroviral agents. This regulatory post-marketing surveillance (PMS) study evaluated the real-life safety and effectiveness of dolutegravir in patients with HIV-1 in clinical practice in Korea.
Materials and Methods:
This open-label PMS study examined data from consecutive patients (aged ≥12 years) with HIV-1 infection receiving dolutegravir according to locally approved prescribing information; treatment-naïve and treatment-experienced patients were permitted. Data regarding patient demographics, medical history, clinical characteristics, medications (HIV-related and concomitant), and comorbidities were extracted from patient records over a 1-year treatment period. Outcomes included the safety of dolutegravir (primary endpoint) and real-life effectiveness according to the Physician Global Assessment (PGA) and the proportion of patients with plasma HIV-1 RNA count <50 copies/mL at 48 weeks.
Results:
Of 147 patients treated with dolutegravir at 18 centers in Korea (August 2014 – August 2020), 139 were eligible for the safety analyses and 75 for effectiveness analyses.Patients (mean age 47 years) were mostly male (92.8%) and received dolutegravir in combination with nucleoside reverse transcriptase inhibitor (70.5%) or protease inhibitors (21.6%). Adverse events (AEs) (n = 179 in total) were mostly mild in severity, with the most common being nasopharyngitis (5.0%), dyspepsia (5.0%), pruritus (4.3%), and rash (4.3%).Of 16 adverse drug reactions (ADRs), the most frequent were rash, diarrhea, headache, insomnia, and somnolence (1.4% each). Of 2 serious ADRs, only 1 (gastroenteritis) was unexpected, and both resolved. The risk of experiencing an AE while receiving dolutegravir appeared to be especially increased in patients receiving concomitant medications for other conditions. Dolutegravir effectively suppressed HIV-1 (93.3% of patients had plasma HIV-1 RNA <50 copies/mL), and 100% of patients showed symptom improvement based on physician global assessment.
Conclusion
Results of this PMS study showed that dolutegravir administered as highly active antiretroviral therapy was well tolerated and effective in patients with HIV-1 infection.

BACKGROUND: As information technology evolves rapidly computer-based surveillance systems for nosocomial infection have been developed. Well designed computerized system could provide an opportunity for improving, enlarging, and conducting hospital-wide surveillance more efficiently in the situation with limited resources. Recently, we launched a new computerized monitoring system in a hospital where digital medical information system has been operated without paper chart. METHODS: We developed a new surveillance program based on the total Electronic Medical Record (EMR) system. Numerous critical medical information can be easily accessible through this system without further work. This includes major demographic data, essential information from the inpatient medical record, the laboratory information system, and the pharmacy information, Comprehensive Clinical Data Repository (CDR) system was also developed. CDR is potentially very useful to conduct a hospital-wide surveillance by integrating all the available information. RESULTS: This system consists of several programs in the EMR and the CDR environment. In the EMR system, inquiry for patients with fever, case ascertainment and registration of nosocomial infections, inquiry for patients with indwelling devices, microbiological reports, and data on antibiotic prescriptions were included. The CDR has integrated comprehensive inquiries for frequency of major pathogens in clinical isolates and their trends of antibiotic resistance, nosocomial infection rates based on the duration of the devices or hospitalization, and the history of antimicrobial usage based on defined daily dosage. Data obtained from the EMR and the CDR systems could be easily accessed by infectious diseases specialists and healthcare workers of infection control services at any place within the hospital. A new reporting system has been built up to facilitate identification of notifiable diseases among the list of diagnoses on the EMR. In addition, the "Alert" notice was designed to highlight isolation precautions for indicated cases. CONCLUSION: This new computerized surveillance program might be a valuable model to which other hospitals can refer to develop newer version of programs in the future.

Journal of Korean Medical Science 2006;21(4):733-738
Gaucher disease is caused by a deficiency of glucocerebrosidase. Patients with Gaucher disease are divided into three major phenotypes: chronic nonneuronopathic, acute neuronopathic, and chronic neuronopathic, based on symptoms of the nervous system, the severity of symptoms, and the age of disease onset. The characteristics of patients with acute neuronopathic- and chronic neuronopathic-type Gaucher disease include oculomotor abnormalities, bulbar signs, limb rigidity, seizures and occasional choreoathetoid movements, and neuronal loss. However, the mechanisms leading to the neurodegeneration of this disorder remain unknown. To investigate brain dysfunction in Gaucher disease, we studied the possible role of inflammation in neurodegeneration during development of Gaucher disease in a mouse model. Elevated levels of the proinflammatory cytokines, IL-1alpha, IL-1beta, IL-6, and TNF-alpha, were detected in the fetal brains of Gaucher mice. Moreover, the levels of secreted nitric oxide and reactive oxygen species in the brains of Gaucher mice were higher than in wild-type mice. Thus, accumulated glucocerebroside or glucosylsphingosine, caused by glucocerebrosidase deficiency, may mediate brain inflammation in the Gaucher mouse via the elevation of proinflammatory cytokines, nitric oxide, and reactive oxygen species.

During the eleven months from September, 1989 to July, 1990, a total of 118 subarachnoid hemorrhage(SAH) patients were admitted. Among these, in 2 cases, the etiology was unknown and another 8 cases of Hunt & Hess clinical grade V patients died in the emergency room or intensive care unit within 24 hours after admission. The remaning 108 cases were managed with protocol as follows. 1) Surgery was done within 9 days after the SAH(total 67 cases) : Extraventricular drainage(EVD) was performed and a cisternal drainage(CD) catheter was positioned during surgery. EVD, CD nimodipine irrigation(0.4mg) through the CD catheter, and intravenous injection(IV) of nimodipine(1~2mg/hr)continued for 13days after the SAH. 2) Surgery was done after the 9th SAH day due to late transfer neurology or other hospitals or posterior circulation aneurysms(32 cases), and 9 cases refused surgery : Nimodipine was used orally(240mg/day) in 35 cases and an IV route(1~2mg/hr) in 6 cases. Total management outcome and results were obtained as follows. 1) A total unsatisfactory management outcome was 18.52%(serve disabled : 4.63%, vegetative : 0.93%, death : 12.96%. In the surgical cases only, 40.8%, 1.02%, 9.19%, respectively). 2) An unsatisfactory surgical outcome in cases following surgery after the 9th SAH day was 6.24%(severe disabled : 3.12%, death : 3.12%). 3) An unsatisfactory management outcome in cases of admission grades I & II following surgery within the 9th SAH day or those non-surgical patients was 19.15%(severe disabled : 4.25%, death : 14.89%. In surgical cases only 2.33%, 9.30%, respectively). 4) An unsatisfactory management outcome in cases of admission grades III & IV with surgery within the 9th SAH day or non-surgical patients was 29.63%(severe disabled : 7.41%, vegetative : 3.70%. death : 18.52%. In surgical cases only 9.09%, 4.55%, 13.64%, respectively). One case of admission grade V died. 5) Causes of unsatisfactory outcome were vasospasm : 9 cases(8.33%), SAH itself : 4 cases, rebleeding : 3 cases, surgical complication : 1 case, medical complication : 1 case, anesthesia : 1 case, and head trauma : 1 case. 6) Complications in management protocol with EVD, CD, CD nimodipine irrigation, and IV of nimodipine were transient hypotension(1 case) and meningitis(5 cases). These complications were improved without sequelae with discontinuing the IV of nimodipine and using antibiotics. We concluded that this protocol may improved the total management outcome of aneurysmal SAH patients, especially poor grade patients(Hunt & Hess grade III & IV) without significant complications. However, in spite of this protocol, the leading cause of an unsatisfactory outcome is vasospasm.

The authors presented 9 cases of surgically treated CSF rhinorrhea, two of which were spontaneous and 7 were traumatic delayed. The duration of leakage was longer than 1 month in most cases and seven of the nine cases were complicated by meningitis. The leakage site was most accurately detected by metrizamide computed tomographic cisternography(MCTC) and the most frequent leakage site was the cribriform plate. Good surgical results were obtained by direct repair and/or shunt without recurrence during follow-up period from 7 months to 2 years.

Eosinophilic cellulitis (EC) is a rare idiopathic disorder, first described as a "recurrent granulomatous dermatitis with eosinophilia", that mimics cellulitis of infectious origin. We describe here a previously healthy 11-year-old girl who experienced fever and tender erythematous patch lesions after trauma to her knees. Because of the relapsing cellulitis-like skin lesions, skin biopsies were taken, resulting in a diagnosis of EC. The patient responded well to oral prednisolone but experienced side effects and relapse during dose tapering. She was switched from prednisolone to cyclosporine. Her EC remained under control, and she showed no evidence of relapse after discontinuation of cyclosporine.
