Neurological complications following liver transplantation are more common than after other organ transplants. These complications include seizure in about 8% of cases, which is associated with morbidity and mortality. Seizure should be treated immediately, and the process of differential diagnosis has to be performed appropriately in order to avoid permanent neurologic deficit. We herein report a case of status epilepticus after liver transplantation. The status epilepticus was treated promptly and the cause of seizure was assessed. The patient was discharged without any complication.

Opioid-induced chest wall rigidity is an uncommon complication of opioids. Because of this, it is often difficult to make a differential diagnosis in a mechanically ventilated patient who experiences increased airway pressure and difficulty with ventilation. A 76-year-old female patient was admitted to the intensive care unit (ICU) after surgery for periprosthetic fracture of the femur neck. On completion of the surgery, airway pressure was increased, and oxygen saturation fell below 95% after a bolus dose of fentanyl. After ICU admission, the same event recurred. Manual ventilation was immediately started, and a muscle relaxant relieved the symptoms. There was no sign or symptom suggesting airway obstruction or asthma on physical examination. Early recognition and treatment should be made in a mechanically ventilated patient experiencing increased airway pressure in order to prevent further deterioration.

BACKGROUND: Hypoglycemia is uncommon in people without diabetes. There have been only a few reports of cardiac arrest in conjunction with hypoglycemia in non-diabetic patients. CASE REPORT: A 66-year-old man visited the emergency room with dizziness. He was a chronic alcoholic. Laboratory test showed no evidence of diabetes mellitus. Brain magnetic resonance imaging revealed a left cerebellar infarction. Abdomen computed tomography demonstrated liver cirrhosis with minimal ascites. During his hospital stay, he consumed only a small amount of food because of nausea and headache. On hospital day 4, he had a cardiac arrest after two seizure episodes. His blood glucose was 10 mg/dL. The combination of liver cirrhosis, renal failure and poor oral intake was presumed to be the causes of the severe hypoglycemia. CONCLUSION: We report a rare case of cardiac arrest occurring in conjunction with severe hypoglycemia in a non-diabetic patient with cerebral infarction.

Background: This study aimed to estimate the annual prevalence and incidence of urolithiasis stratified by work status based on a large nationwide sample. Methods: This study used data from the National Health Insurance Service-National Sample Cohort from 2002 to 2015. The prevalence and incidence of urolithiasis were estimated based on work status and gender stratification. The risk of urolithiasis among workers was calculated using age-standardized incidence ratio with stratification of work type. Results: The prevalence of urolithiasis was significantly higher in workers than in non-workers, especially men, during the follow-up period. The total estimated number of urolithiasis cases was 41,086 and the overall incidence of urolithiasis was 0.3%. The age-standardized incidence ratio of urolithiasis was significantly higher among the total workers (1.14; 95% confidence interval, 1.13–1.16), self-employed workers (1.08; 95% confidence interval, 1.06–1.11), and paid workers (1.19; 95% confidence interval, 1.17–1.21) than among the non-working population. Conclusions Workers, especially paid workers and men, were vulnerable to urolithiasis. Further studies are required to investigate the effects of working conditions on urolithiasis.

Background: The diagnosis of food allergies needs to be confirmed through an oral food challenge (OFC). However, specific immunoglobulin E (sIgE) concentrations analyzed by serological tests are also helpful in determining OFC items and predicting the presence of allergic reactions. Unfortunately, there is a limit to the number of antigens that can be simultaneously evaluated at one time. The purpose of this study was to analyze the possibility of detecting sIgE antibodies against food using clues in self-reported food allergy symptoms. Methods: Medical records of 377 patients aged 3 years or younger were collected for egg white-, cow’s milk-, walnut- and soybean-sIgE sensitization, and related clinical history. Each clinical history was classified into class 1: direct- isolated intake resulting in anaphylaxis or hives with consistent clincical history; class 2a: class 1 with inconsistency; class 2b: indirect-mixed intake resulting in anaphylaxis or hives regardless of consistency; class 2c: direct/indirect- isolated/mixed intake resulting in itching without hives, vomiting, or diarrhea with consistent clincical history; or class 3: class 2c with inconsistency or asymptomatic to direct, isolated exposure. Results: The area under the curve (AUC) of class 1 for cow’s milk was 0.790, and the accuracy was 78.0%. The AUC of class 1 and 2 for egg white was better than that of class 1 (0.750), and the accuracy rate was 77.6%. The AUCs of class 1 for walnut and soybean were 0.775 and 0.662, respectively. Conclusion In conclusion, sIgE sensitization to foods could be predicted by the combination of exposure and selfreported symptoms in children under 3 years of age.

Purpose: Perilla seed (PS) is the most common cause of seed-induced anaphylaxis in Korean children, but the reports on PS allergy, including phenotype and cross-reactivity, are rare. The aim of this study is to assess the clinical characteristics of PS allergy and investigate cross-reactivity with sesame seed (SS). Methods: Through a retrospective medical record review, patients with clinical PS allergy were identified in a single tertiary hospital. Clinical characteristics of allergic reaction upon exposure to PS and SS, results of skin prick test (SPT) to PS and SS, and the levels of serum SS-specific immunoglobulin E (SS-sIgE) were investigated. Cross-reactivity between PS and SS was studied using IgE enzymelinked immunosorbent assay (ELISA) inhibition. Results: The median age of 34 PS-allergic children was 41.5 months (range, 10 months to 12 years), and the proportion of anaphylaxis upon exposure to PS was 29.4% (n = 10). The PS SPT was positive in 94.1% (n = 32) with the median wheal size of 6.25 mm. Among PS-allergic children, the percentages of patients with positive symptoms, negative symptoms, and indeterminate symptoms upon exposure to SS were 8.8%, 41.2%, and 50%, respectively. Out of 14 PS-allergic children who were tolerant to SS, positive sensitization to SS was noticed in 78.6% by serum SS-sIgE, and 57.1% by SS SPT. Partial cross-reactivity between PS and SS was identified in IgE ELISA inhibition. Conclusion This study reported the clinical profiles and SPT results in a relatively large number of PS-allergic children and identified the partial cross-reactivity between PS and SS for the first time.

Barley is not a rare dietary content in Asian food but very few cases of anaphylactic reactions to barley have been reported. Furthermore, most reports are in adult patients with allergic reactions to beer containing barley components or occupational asthmatics known as 'baker's asthma'. We present a case of 11-month old boy who experienced an episode of anaphylaxis with generalized urticaria, periorbital swelling, wheeze and dyspnea after eating baby food containing barley, chestnut, glutinous rice, nonglutinous rice, within 30 minutes. Laboratory tests demonstrated high total serum IgE (531 kU/L) and revealed high level of IgE sensitizations to wheat (64.3 kU/L), barley (35.2 kU/L), rice (1.39 kU/L). Using the IgE-immunoblot assay, 7, 14, 25, and 26 kDa of IgE binding bands were identified and high degree of IgE cross-reactivity between barley and wheat extracts were revealed using IgE-immunoblot inhibition and ELISA-inhibition tests in this case.

PURPOSE: The immunological characteristics of young Korean children with walnut (WN) allergy and the influence of different cooking methods on WN proteins have not been evaluated to date. This study aimed to evaluate the major WN allergens identified among Korean children, together with changes in WN antigenicity caused by common cooking methods. METHODS: We enrolled children under the age of 13 years with WN serum-specific immunoglobulin (Ig) E concentrations. The protein fractions of dry-fried and boiled WN extracts were compared with those of raw WNs using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), 2-dimentional gel electrophoresis (2DE) and a proteomic analysis using electrospray ionization (liquid chromatography-mass spectrometry [LC-MS]). An immunoblotting analysis was conducted to examine IgE reactivity toward raw WNs using serum samples from 6 children with a clinical WN allergy. To determine the processed WN proteins with IgE-binding capacity, a 2D-immunoblotting analysis was performed using the pooled sera of 20 WN-sensitized children. RESULTS: Protein bands from raw WNs were identified at 9, 16, 28, 52, 58, and 64 kDa via SDS-PAGE. The 9- and 16-kDa protein bands were enhanced by boiling, whereas the 52- and 64-kDa bands were considerably diminished. On LC-MS analysis, of the 66 IgE-binding proteins present in raw WNs, 57 were found in dry-fried WNs, but only 4 in boiled WNs. The sera of 5 out of 6 participants reacted with the 52-kDa protein bands and those of 4 out of 6 participants reacted with the 16- and 28-kDa protein bands, respectively. Meanwhile, a 2D-immunoblotting result confirmed the presence of different binding patterns among children who consumed cooked WNs. CONCLUSIONS: The protein profile of boiled WNs is substantially different from that of raw WNs. However, 4 proteins including prolamins remained stable after dry-frying or boiling. Further studies are needed to evaluate the clinical relevance of these findings.
