ABSTRACT
Listeria monocytogenes is a rare cause of bacterial meningitis, particularly beyond the neonatal period. This article describes a 16-month-old girl who presented with a new-onset febrile status epilepticus, and subsequently developed altered mentality and lethargy. L. monocytogenes was detected on a point-of-care, multiplex polymerase chain reaction using the cerebrospinal fluid. On day 3, she developed a rapidly progressive hydrocephalus. Her consciousness improved after placement of an external ventricular drain. After 3-week antibiotic therapy, she was successfully discharged without residual complications.
ABSTRACT
Pulmonary epithelioid hemangioendothelioma (PEH) is a rare vascular tumor of borderline or low-grade malignancy, and its prognosis is unpredictable. Herein, we describe the case of a 47-year-old asymptomatic female with a diagnosis of multinodular PEH. During a 7-year followup, the nodules with large size and high 18F-fluorodeoxyglucose uptake in the initial study showed progression with increasing sizes; however, most small nodules (size < 1 cm) demonstrated spontaneous regression with peripheral rim or nodular calcification. The patient underwent surgical resection for an enlarged nodule. Of note, it is unusual for an individual to have mixed progression and regression concomitantly, which may be helpful in predicting the prognosis.
ABSTRACT
Intraluminal duodenal diverticulum (IDD) is a rare congenital abnormality, consisting of a sac-like mucosal lesion in the duodenum. Cases of IDD can present with gastrointestinal bleeding, duodenal obstruction, or pancreatitis. Here, we report a rare case of a 25-year-old female presenting with IDD complicated by duodeno-duodenal intussusception and recurrent pancreatitis. The diagnosis was based on findings from radiologic examinations (CT and MRI), upper gastrointestinal series (barium swallow), and gastroduodenofiberscopy. Laparoscopic excision of the presumed duodenal duplication was performed. The subsequent histopathologic evaluation of the excised sac revealed normal mucosa on both sides, but the absence of a proper muscle layer confirmed the diagnosis of IDD. Radiologic detection of a saccular structure in the second portion of the duodenum can indicate IDD with duodeno-duodenal intussusception as the lead point
ABSTRACT
To date, there is no standardization of the endoscopi c retrograde cholangiopancreatography (ERCP) room setting regarding with the size, equipment or space arrangement. Therefore, the authors visited 11 tertiary hospitals that recently remodeled or newly designed the ERCP room to analyze and identify their advantages and disadvantages. The ERCP room should have enough space for equipments including fluoroscopy, endoscopy, electrosurgical unit, preparation table and for patient movement. The EUS room does not require an independent space unless it is a very large scale hospital, and the ERCP room can be shared. Considering the pros and cons of each equipment, adequate fluoroscopic device should be selected depending on the hospital circumstance. Expensive equipment for X-ray fluoroscopy system is not necessarily good, and it is necessary to install equipment suitable for each hospital situation by understanding the advantages and disadvantages of fluoroscopy. For prevention of ERCP-related radiation hazard, both endoscopist and assistants should wear radiation-blocking apron, thyroid protectors, and lead glasses. Furthermore, a shield that can block radiation between the endoscopist and the patient should be installed to protect high-energy scattered waves. One-way direction should be designed to prevent cross infection when moving the endoscopic equipment from the ERCP to the cleaning room. If possible, it is recommended to keep a cardiopulmonary resuscitation cart in the ERCP room.
ABSTRACT
Background@#This study aimed to analyze the correlation between bone mineral density (BMD) and the type of 5th metatarsal fracture, as well as to demonstrate whether there is a difference in radiological findings (heel alignment angle [HAA], heel moment arm [HMA], and metatarsus angle) between fracture types. @*Methods@#A total of 87 patients were enrolled in the study and allocated into 3 groups: the Zone 1 group (N=36), the Zone 2 group (N=33), and the Zone 3 group (N=18). The participants’ demographic data, T-scores, existing fracture or osteoporosis medications, and radiologic parameters including HAA, HMA, and metatarsus adductus angle were analyzed and compared. @*Results@#There was a significant difference between the mean age of the participants, with the highest age in the Zone 1 group and the lowest in the Zone 3 group. Regarding the history of concurrent fracture or osteoporosis medications, there was no significant difference between the 3 groups. Similarly, no significant difference was observed between the 3 groups about the BMD values. In contrast, the HAA was statistically significant in all groups with a positive correlation of -8.9 in the Zone 1 group, a negative correlation of 3.55 in the Zone 2 group, and an inverse relationship of 6.1 in the Zone 3 group. The metatarsus adductus angle was significantly higher in the Zone 3 group than the Zone 1 and Zone 2 groups. @*Conclusions@#The location of a 5th metatarsal bone fracture is not significantly associated with BMD. However, mechanical influences, such as hindfoot varus or forefoot adductus, have a significant correlation with fracture types.
ABSTRACT
Objective@#No previous study examined impact of dementia in the outcome of allogeneic hematopoietic stem cell transplantation (HSCT). We aimed to investigate overall survival (OS) of patients with dementia after receiving HSCT. @*Methods@#Among 8,230 patients who underwent HSCT between 2002 and 2018, 5,533 patients younger than 50 years were first excluded. Remaining patients were divided into those who were and were not diagnosed with dementia before HSCT (dementia group: n = 31; no dementia: n = 2,666). Thereafter, among 2,666 participants without dementia, 93 patients were selected via propensity-matched score as non-dementia group. Patients were followed from the day they received HSCT to the occurrence of death or the last follow-up day (December 31, 2018), whichever came first. @*Results@#With median follow-up of 621 days for dementia group and 654 days for non-dementia group, 2 year-OS of dementia group was lower than that of non-dementia group (53.3% [95% confidence interval, 95% CI, 59.0−80.2%] vs. 68.8% [95% CI, 38.0−68.2%], p = 0.076). In multivariate analysis, dementia had significant impacts on OS (hazard risk = 2.539, 95% CI, 1.166−4.771, p = 0.017). @*Conclusion@#Our results indicated that patients diagnosed with dementia before HSCT have 2.539 times higher risk of mortality after transplantation than those not having dementia. With number of elderly needing HSCT is increasing, further work to establish treatment guidelines for the management of HSCT in people with dementia is needed.

ABSTRACT
Background@#Diabetic neuropathic osteoarthropathy (DNOAP) is known as debilitating diabetes complications. The aim of study is to compare bone mineral density (BMD) among diabetic foot and DNOAP, and investigate the impact of BMD proceeded from diabetic foot to DNOAP. @*Methods@#A DNOAP group (subgroup A and subgroup B) and control group were examined for this study. Subgroup A (n=21) were patients diagnosed with DNOAP with the development of new foot and ankle fractures, whereas subgroup B (n=4) were patients being managed with the diabetic foot before a diagnosis of DNOAP. BMD was also evaluated before the diagnosis. Control group (n=30) was diabetic foot patients without DNOAP. The demographic data, clinical and radiologic data, comorbidities, and BMD were compared for each group. And optimal BMD score was reviewed to predict fractures in neuropathic arthropathy. @*Results@#BMD was significantly lower in DNOAP group (group A and B) compared with control group. Also neuropathic arthropathy group showed poor radiological results. After comparisons of 2 group lumbar and femur BMD was significantly different, but logistic regression analysis revealed that low femur T-score could be risk predictors of the condition. Base on the data of group B and control group, the cut-off point for predicting foot and ankle fracture-related with DNOAP was -1.65 of femur BMD. @*Conclusions@#Low BMD shows greater incidence in foot and ankle fracture patients associated with neuropathic arthropathy. A femur T score can be a risk predictor of diabetic neuropathic arthropathy for diabetic foot patients.
ABSTRACT
Kv3family K + channels, by ensuring speedy repolarization of action potential, enable rapid and high frequency neuronal firing and high precision temporal coding of auditory information in various auditory synapses in the brain. Expression of different Kv3 subtypes within the auditory end organ has been reported. Yet, their precise role at the hair cell synaptic transmission has not been fully elucidated. Using immunolabeling and confocal microscopy we examined the expression pattern of different Kv3 family K + channel subunits in the nerve fibers innervating the cochlear hair cells.Kv3.1b was found in NKA-positive type 1 afferent fibers, exhibiting high signal intensity at the cell body, the unmyelinated dendritic segment, first heminode and nodes of Ranvier.Kv3.3 signal was detected in the cell body and the unmyelinated dendritic segment of NKA-positive type 1 afferent fibers but not in peripherin-positive type 2 afferent. Kv3.4 was found in ChAT-positive LOC and MOC efferent fibers as well as peripherin-positive type 2 afferent fibers. Such segregated expression pattern implies that each Kv3 subunits participate in different auditory tasks, for example, Kv3.1b and Kv3.3 in ascending signaling while Kv3.4 in feedback upon loud noise exposure.
ABSTRACT
OBJECTIVES: This study aimed to compare customers' perceptions of the need for a low-sodium diet and sodium-reduced operations in the industry foodservice by age. The relationships between health concerns and perceptions of the need for sodium-reduced operations and low-sodium diets in the industry foodservice were analyzed.METHODS: A survey was conducted among 340 industry foodservice customers aged 20–50 years and residing in Seoul, Korea. This study investigated the respondents' health concerns, their perception of the need for sodium-reduced foodservice operations, their perception of a sodium-reduced diet, and the general details of the foodservices they used. A cross-tabulation analysis and ANOVA were performed to identify differences in measurement items by age, and a simple regression analysis was performed to examine relationships between measurement items.RESULTS: For the customers' perception of the need for a sodium-reduced foodservice operation, the item “it is necessary to provide separate spices and sauces to reduce sodium intake” achieved the highest score (3.88 points out of a possible 5 points). For the perception of a sodium-reduced diet, the item “I think it is helpful for one's health” obtained the highest score (4.13 points). Respondents' health concerns had a positive effect on increasing the level of perception of the need for sodium-reduced foodservice operations and that of a sodium-reduced diet.CONCLUSIONS: Foodservice nutritionists could help enhance their customers' perceptions of the needs for sodium-reduced foodservice operations and sodium-reduced diets by frequently providing them with sodium-related health information.

Materials and Methods@#Rats in the abnormal diurnal temperature group and control group were given a 10 mm sized full-thickness skin ulcer. Wound size progression was observed in both groups. H&E and Masson’s trichrome staining was performed at 14 days after wound formation, and the number of vessels per unit area and histology analysis were performed. The changes in the ulcer were measured through three dimensional cross-section area using INSIGHT® devices. @*Results@#The wound recovery period (granulation ingrowing) was 24 days in the abnormal diurnal temperature model and 20 days in the control group. The thickness of scar tissue was 402±23.19 μm in the control group and 424.5±36.94 μm in the diurnal temperature model. Neovascular formation was counted as 5.1±0.97 for the control group and 4.16±0.94 for the diurnal temperature model group. @*Conclusion@#Delayed and inferior diabetic wound healing was observed in the abnormal diurnal temperature group, which was characterized by greater diurnal variations than the typical growth environment.

ABSTRACT
In clinical practice, recurrent Achilles ruptures have been noted to occurr at the original ruptured site. However, reports of new developed fresh rupture of the Achilles tendon in other sites are is extremely rare. Our report is about one uncommon case of a traumatic calcaneal tuberosity avulsion fracture following augmented repair, which was performed using the Krackow locking loop technique. We performed open reduction and intra-osseous fixation using a suture anchor. This procedure was done through the primary longitudinal incision for the calcaneal avulsion fracture fragment. After 6 months of follow-up, our patient has achieved a complete functional recovery and he can normally perform daily and work-related tasks without pain.
ABSTRACT
PURPOSE@#Lennox-Gastaut syndrome (LGS) is one of the most severe epileptic encephalopathies and frequently patients with this syndrome respond poorly to antiepileptic drugs. The aim of this study was to evaluate the treatment outcomes of vagus nerve stimulation (VNS) in LGS patients with drug-resistant epilepsy.@*METHODS@#We analyzed the clinical files, collected over 5 years, of children with LGS who received VNS treatment.@*RESULTS@#Seven children were included in this study (four males, three females; mean age of VNS insertion 12.4±3.5 years). All the patients had generalized tonic seizures and there were various other seizure types including myoclonic seizures, atonic seizures, and atypical absence seizures. Although two patients had normal imaging, five patients had abnormalities on imaging, including pachygyria, cortical dysplasia, kernicterus, and a chromosomal anomaly. Comparing the baseline seizure frequency to the frequency after the VNS surgery, the seizure frequency at the last follow-up showed a decrease of 57.2% (0% to 100%) on average (P=0.028) and one patient achieved seizure free status. Only two children were given additional antiepileptic drugs with the aim of managing their seizures. There was no mortality or complications related to the VNS therapy except one case requiring intensive care unit admission due to pneumonia. Comparing the results before and after VNS surgery, the VNS therapy also had a tendency to have a positive effect on quality of life (P=0.066).@*CONCLUSION@#In LGS patients with drug resistant epilepsy who are not candidates for a corpus callosotomy or resective surgery, VNS could be an effective, low-risk adjunct therapy for decreasing seizure frequency.
ABSTRACT
BACKGROUND: Peripheral arterial disease (PAD) is known as the greatest risk factor affecting the amputation of diabetic foot. Thus, it is crucial to understand the epidemiology of PAD associated with diabetic foot and the relationship between PTA and amputation in predicting prognosis. However, no such multi-year data are available in Korea. Thus, the purpose of this study was to investigate trends of amputation involving diabetic foot based on vascular interventions for PAD in Korea. METHODS: This study was conducted using six-year data obtained from Health Insurance Review and Assessment Service from January 1, 2011 to December 31, 2016. Our study included data pertaining to diabetic foot, PAD, and vascular intervention codes (percutaneous transluminal angioplasty [PTA, M6597], percutaneous intravascular installation of stent-graft [PIISG, M6605], and percutaneous intravascular atherectomy [PIA, M6620]). We analyzed the number of vascular interventions and minor and major amputations each year. The relationship between annual amputation and vascular intervention was analyzed using χ² test. RESULTS: The overall number of vascular interventions increased from 253 (PTA, 111; PIISG, 140; and PIA, 2) in 2011 to 1,230 (PTA, 745; PIISG, 470; and PIA, 15) in 2016. During the same period, the number of minor amputations increased from 2,534 to 3,319 while major amputations decreased from 980 to 956. The proportion of minor amputations among patients who underwent vascular intervention was significantly increased from 19.34% in 2011 to 21.45% in 2016 while the proportion of major amputations among these patients was significantly reduced from 9.88% to 4.27%. In addition, the association between vascular intervention and amputation increased from 0.56 (spearman correlation coefficient) in 2011 to 0.62 in 2016. CONCLUSION: In diabetic foot patients, increase in vascular intervention resulted in a change in amputation pattern, showing statistically significant correlation.

PURPOSE: To investigate the spatial distribution of diabetes-related lower limb amputations and analyze the relationship between the spatial distribution of diabetes-related lower limb amputations and regional factors. MATERIALS AND METHODS: This study was performed based on the data from the Korean Health Insurance Review and Assessment Service, in 2016. The unit of analysis was the administrative districts of city·gun·gu. The dependent variable was the age- and sex-adjusted incidence of diabetes-related lower limb amputations and the regional variables were selected to represent two aspects: socioeconomic factors, and health and medical factors. Along with traditional ordinary least square (OLS) regression analysis, geographically weighted regression (GWR) was applied for spatial analysis. RESULTS: The age- and sex-adjusted incidence of diabetes-related lower limb amputation varied according to region. OLS regression showed that the incidence of diabetes-related lower limb amputation had significant relationships with the health and medical factors (number of healthcare institution and doctors per 100,000 population). In GWR, the effects of regional factors were not consistent. CONCLUSION: The spatial distribution of the incidence of diabetes-related lower limb amputations and the effects of regional factors varied according to the regions. The regional characteristics should be considered when establishing health policy related to diabetic foot care.

PURPOSE: An ingrown nail is common in military trainees who are exposed to highly demanding activities. Although the matrixectomy procedure has been the main treatment modality, several drawbacks may follow after the procedure, such as infection, periostitis, and continued pain that causes a delayed return to duty. This study examined the outcomes of a simple partial nail extraction with the hypothesis that this procedure may bring an earlier return to duty, lower the perioperative complications, and produce a comparable recurrence rate. MATERIALS AND METHODS: The medical records of patients who had surgical treatment for an ingrown nail in the authors' institution between April 2016 and December 2017 were reviewed retrospectively. Under the inclusion and exclusion criteria, 28 patients with a simple partial nail extraction (group A) and 29 patients with a partial nail extraction with matrixectomy (group B) were investigated. As the clinical outcome, the visual analogue scale (VAS) and satisfaction score, time to return to duty, complications, and recurrence rate were checked and compared between the groups. RESULTS: The VAS scores of group B were significantly higher during the first (p<0.001) and second (p=0.026) follow-up week than group A. The time to return to duty was shorter in group A (7.8 days) than group B (10.1 days), and this difference was significant (p<0.001). Group B had five patients with complications, whereas group A had none (p=0.028). No differences in the recurrence rate (p=0.197) and patient satisfaction (p=0.764) were found between the groups. CONCLUSION: In this study, simple partial nail extraction in military trainees resulted in lower postoperative pain, lower complication rates, and earlier return to duty than the procedure with matrixectomy. Military trainees are temporarily exposed to highly demanding activities. Thus, a satisfactory outcome would be expected with simple partial nail extraction without performing a radical procedure, such as a matrixectomy.

BACKGROUND/AIMS: The aim of this study is to describe the outcome of the national survey and to determine the endoscopic retrograde cholangiopancreatography (ERCP) quality in Korea by comparing with the quality indicators. METHODS: We used the database of Health Insurance Review & Assessment Service and then performed anonymous national survey. RESULTS: Completed questionnaires were returned by 129 of 157 ERCP endoscopists. In Korea, annual ERCP rates have been consistently increased over years. Individual ERCP volume was high (>200 per year) in about half of ERCP endoscopists. Most ERCP endoscopists performed all of level I procedures. However, manometry, cholangiopancreatoscopy, and pancreatic procedures were performed mostly in institutions with high hospital volume. The rate of overall success was more than 90% in most ERCP endoscopists. However, the rate of precut sphincterotomy was high in more than a fourth of ERCP endoscopists. Twelve ERCP endoscopists experienced post-ERCP mortality within recent 1 year. ERCP training and radiation protection during ERCP did not meet the standard of quality indicators especially in institutions with low or moderate hospital volume. CONCLUSIONS: Technical issues during ERCP procedures in Korea fulfill the standard of quality indicators. However, a great effort is needed to improve issues about ERCP training and radiation protection.
