Pneumocephalus is defined as the presence of air or gas within the cranial cavity. It is usually associated with disruption of the continuity of the skull after head and facial trauma, neuro or otorhinolaryngologic surgery, and rarely, spontaneously. But a case of pneumo-hydrocephlus, a special subtype of pneumocephalus, has been rarely reported. This is a case of a 26-year-old quadriplegic patient who traumatic brain injury with left frontoparietal skull bone fracture and epidural hemorrhage with developed of pneumo-hydrocepahlus in the ventricle 6 months after injury. The mechanism of this case can be explained by the "inverted bottle" hypothesis. Clinical observation suggests that the leakage of cerebrospinal fluid through the ventricle-peritoneal shunt tube caused negative pressure gradient differences resulting in the inflow of outside air into the ventricle through fissures created by concealed fracture of the skull base.

Scabies is a skin disease caused by the parasite Sarcoptes scabiei var. hominis, primarily transmitted via direct skin or sexual contact or, less commonly, via contact with infested fomites. In Korea, the incidence of scabies has decreased from approximately 50,000 people/yr in 2010 to approximately 30,000 people/yr in 2021. However, outbreaks have been consistently observed in residential facilities, such as nursing facilities, particularly among the older population. The clinical manifestations of scabies vary depending on a patient’s age, health status, number of mites, and transmission route. Typical clinical presentations of classic scabies include intense nocturnal pruritus and characteristic skin rashes (burrows and erythematous papules), with a predilection for the interdigital web spaces, inner wrists, periumbilical areas, axillae, and genital areas. Unlike classic scabies, older adults with immunodeficiency or neurological disorders exhibit hyperkeratotic scaly lesions or an atypical distribution with mild-to-non pruritus (crusted scabies). Diagnosis of scabies is based on clinical symptoms and results of diagnostic tests aimed at identifying the presence of the parasite. Although a close contact history and characteristic clinical findings are suggestive of scabies, confirmation of diagnosis requires detection of scabies mites, eggs, or scybala.This can be achieved through light microscopy of skin samples, non-invasive dermoscopy, and other high-resolution in vivo imaging techniques.

For all suspected, clinical, or confirmed cases of scabies, treatment should be initiated. Affected patients should be adequately isolated, and high-risk groups with close contact histories should be treated irrespective of their symptoms. Optimal treatment strategies can be selected based on age, clinical subtype, and patient’s health status. In Korea, commercially available preparations for scabies treatment include topical 5% permethrin, topical 10% crotamiton, and oral ivermectin. Topical 5% permethrin is the first-line selective treatment for both classic and crusted scabies. Alternative treatments are topical 10% crotamiton and oral ivermectin. Following treatment completion, a follow-up visit at 2 and 4 weeks is recommended to monitor therapeutic response. Treatment failure is considered when scabies mites or burrows are detected, upon development of new clinical characteristics, or upon aggravation of pruritus. Scabies itch should be adequately managed with emollients, oral antihistamines, and topical corticosteroids. Preventive measures, including personal hygiene, patient education, and environmental control should be rendered to reduce the transmission of scabies.

"Trigger finger at the wrist" is a rare phenomenon. The main symptom consists in a triggering at the wrist produced by finger motion. Its etiology and presentation may vary. One of etiology, some anomalies of muscle can cause this disease. Triggering finger at the wrist with carpal tunnel syndrome by abnormal the belly of the flexor digitorum superficialis has been reported. But most cases of it have been reported by orthopedic surgeons. We are presenting the case of 28 year old male patient who had abnormal flexor digitorum superficialis in carpal tunnel which was diagnosed by using ultrasonography.

OBJECTIVE: To improve the quality of life of the disabled population by decreasing the incidence of complications and chronic diseases and improving self-care abilities according to individual diseases through health status evaluation and basic survey. METHOD: The basic clinical information of 1,378 regional severely-disabled patients were collected along with information regarding functional level, activities of daily living, nutritional status, and management of complications which were distinguished into 3 stages (good, moderate, poor), which were correlated into scores (1-3 points) that were used to assess a collaborative score (5-15 points) that represented their health status. Health behavior and blood tests were also done. RESULTS: Health status were evaluated based on sex, grade of disability, age, frequency of exercise and type of disability, which revealed that female sex, brain disorder, 1st grade disability, total lack of exercise, old age disabled patients were relatively poor in terms of health status. CONCLUSION: Health status of the severely-disabled showed differences according to sex, age, grade of disability, type of disability, and frequency of exercise, and health programs designed to screen and follow up the severely-disabled person with poor health status as well as manage their accompanying diseases and complications are needed.

Food allergy has emerged as an important public health problem affecting people of all ages in many countries. The prevalence varies according to age, geographic regions, and ethnicity. For several years, many studies have suggested that the prevalence of food allergy is increasing at an alarming rate, for unclear reasons. Conversely, some studies have also provided findings that sensitization to common food allergens did not increase. Increased recognition rather than an actual increase in patients with IgE-mediated food allergy might lead to the increases in the prevalence of self-reported or physician-diagnosed food allergy. It is also noted that the prevalence of food allergy differs even in the same region according to the study design, i.e., hospital-based or community-based studies. Despite these limitations, epidemiologic data are important because they provide useful information on diagnosis, treatment, and prevention of food allergy. This review focuses on advances in the epidemiology of food allergy in Korean children.

With increasing need to prevent serious food allergy reactions, Korean food allergen labeling regulation has been revised repeatedly. This paper aims to summarize current statuses of food allergen labeling in Korea and foreign countries and to analyze the issue of food allergen labeling regulation. Korean food labeling regulation currently requires 19 items and 22 foods to be reported on labels (eggs, milk, buckwheat, peanut, soybean, wheat, mackerel, crab, shrimp, pork, peach, tomato, sulfite, walnut, chicken, beef, squid, shellfish, and pine nut). However, some common food triggers (for example, almond, cashew nut, and kiwi fruit) are not included in the current labeling regulation. Another issue is that the Korean labeling regulation has not yet been fully implemented for nonprepacked foods; thus, consumers still have difficulty in correctly identifying allergenic ingredients in food. It should be assessed whether warning statements for cross-contamination are reasonable. To prevent the occurrence of serious reactions from accidental ingestion, efforts must be made to solve recently raised issues including the items required to be listed on food labels, the system of standards for labeling and display methods.

BACKGROUND: Anaphylaxis is increasing in young children. The aim of the present study was to analyze the clinical characteristics of anaphylaxis in Korean infants, with a focus on food triggers. METHODS: The study analyzed the medical records of infants aged 0 to 2 years old who had been diagnosed with anaphylaxis in 23 secondary or tertiary hospitals in Korea. RESULTS: We identified 363 cases of infantile anaphylaxis (66.9% male). Cutaneous symptoms were most prevalent (98.6%), followed by respiratory (83.2%), gastrointestinal (29.8%), and neurologic (11.6%) symptoms. Cardiovascular symptoms were noted in 7.7% of the cases. Most of the cases of anaphylaxis (338; 93.1%) were induced by foods. The most common trigger food was cow's milk and cow's milk products (43.8%), followed by hen's eggs (21.9%), walnuts (8.3%), wheat (7.7%), peanuts (4.8%), other nuts (3.0%), and fish (2.1%). In cow's milk-induced anaphylaxis cases, more than half the cases had cow's milk specific immunoglobulin E (sIgE) levels that were lower than the diagnostic decision points (DDPs), which is 5 kUA/L for those under the age of 1 and 15 kUA/L for those over the age of 1. In anaphylaxis induced by hen's egg, most of the cases (91.8%) had hen's egg sIgE levels that were higher than the DDP, which is 2 kUA/L for those under the age of 2 and 7 kUA/L for those over the age of 2. Of the infantile anaphylaxis cases, 46.8% had been treated with epinephrine, and 25.1% had been prescribed an epinephrine auto-injector. CONCLUSION: Cow's milk is the most frequent trigger food of anaphylaxis in Korean infants. However, we found no significant correlation between the sIgE level and clinical severity. Education is required regarding the importance of epinephrine as the first line therapy for anaphylaxis and on properly prescribing epinephrine for infants with a history of anaphylaxis.

PURPOSE: Age-based causes and clinical characteristics of immediate-type food allergy (FA) have not been sufficiently studied. Therefore, we investigated age-dependent clinical profiles of FA in Korean children through an extensive multicenter investigation. METHODS: Using a case report form developed by the authors, a retrospective medical record review was performed of patients (0-18 years old) diagnosed with immediate-type FA between September 2014 and August 2015 in 14 tertiary hospitals in Korea. RESULTS: A total of 1,353 children and adolescents, 93% younger than 7 years, were enrolled in the present study, and 1,661 cases of immediate-type FA were recorded in these patients. The 7 major causative foods were cow's milk (28.1%), hen's eggs (27.6%), wheat (7.9%), walnuts (7.3%), peanuts (5.3%), buckwheat (1.9%), and shrimps (1.9%). Categorizing the patients into 4 age groups revealed that the most common causative food was different for each age group: cow's milk (<2 years), walnuts (2–6 years), walnuts (7–12 years), and buckwheat (13-18 years). The onset time of symptoms was less than 10 minutes in 49%, between 10 and 30 minutes in 17%, and between 30 minutes and 2 hours in 34% of cases. Food-induced anaphylaxis was reported in 506 (30.5%) out of 1,661 cases, and the 7 major causes of food-induced anaphylaxis was cow's milk (27.5%), hen's eggs (21.9%), wheat (11.3%), walnuts (10.5%), peanuts (5.9%), buckwheat (4.2%), and pine nuts (3.0%). The proportion of anaphylaxis was highest in the patients allergic to buckwheat (67.7%), followed by those allergic to pine nuts (57.7%), walnuts (43.8%), wheat (43.5%), and peanuts (34.1%). CONCLUSIONS: The 5 major causative foods of immediate-type FA in Korean children were cow's milk, hen's eggs, wheat, walnuts, and peanuts. The distribution of causative foods was considerably distinctive according to different age groups. Anaphylaxis was reported in 30.5% of immediate-type FA cases.

Background: Atopic dermatitis (AD) is a heterogeneous disease with different age of onset, disease course, clinical symptoms, severity, and risk of comorbidity. The characteristics of children with AD also vary by age or country. However, little is known about the clinical characteristics of AD in Korean school-aged children and adolescents. Furthermore, there are few studies on phenotypic differences according to onset age. This study aimed to explore the clinical characteristics and phenotypes according to onset age and severity of AD in children and adolescents in Korea. Methods: AD patients aged 6–18 years who presented to 18 hospitals nationwide were surveyed.The patients were examined for disease severity by pediatric allergy specialists, and data on history of other allergic diseases, familial allergy history, onset age, trigger factors, lesion sites,treatment history and quality of life were collected. The results of the patient’s allergy test were also analyzed. The patients were classified into infancy-onset (< 2 years of age), preschoolonset (2–5 years of age), and childhood-onset (≥ 6 years of age) groups. Study population was analyzed for clinical features according to onset-age groups and severity groups. Results: A total of 258 patients with a mean age of 10.62 ± 3.18 years were included in the study. Infancy-onset group accounted for about 60% of all patients and presented significantly more other allergic diseases, such as allergic rhinitis and asthma (P = 0.002 and P = 0.001, respectively). Food allergy symptoms and diagnoses were highly relevant to both earlier onset and more severe group. Inhalant allergen sensitization was significantly associated with both infancy-onset group and severe group (P = 0.012 and P = 0.024, respectively). A family history of food allergies was significantly associated with infancyonset group (P = 0.036). Severe group was significantly associated with a family history of AD, especially a paternal history of AD (P = 0.048 and P = 0.004, respectively). Facial (periorbital, ear, and cheek) lesions, periauricular fissures, hand/foot eczema, and xerosis were associated with infancy-onset group. The earlier the onset of AD, the poorer the quality of life (P = 0.038). Systemic immunosuppressants were used in only 9.6% of the patients in the severe group. Conclusion This study analyzed the clinical features of AD in Korean children and adolescents through a multicenter nationwide study and demonstrated the phenotypic differences according to onset age and severity. Considering the findings that the early-onset group is more severe and accompanied by more systemic allergic diseases, early management should be emphasized in young children and infants.
