There are various complex formations between immunoglobulin and serum enzymes in the body. Of these, LD-Immunoglobulin complex is most common. It has reported that LD-IgG or LD-IgA complex existed in the serum of healthy person or many patients who have various clinical disorders. The clinical significance of complexes is not known, but it results in the increase of total LD activity and interference to the LD isoenzyme electrophoresis interpretation due to its anomalous pattern. We have reported a case of LD-Immunoglobulin complex in AILD(Angioimmunoblastic lymphadenopathy with dysproteinemia) with reference. The patient was admitted with fever, chills and cervical LN enlargement, in LN biopsy, diagnosed AILD, and during treatment expired by sepsis. Since admission, serum total LD activities were increased and serum LD isoenzyme EP showed that LD3-5 fractions was not separated in broad single band. Its pattern was due to LD-immunoglobulin complex, LD-bound immunoglobulin was IgG ,lamda. For the identification of immunoglobulin, we at first did serum protein immunoelectrophoresis. then stained the plate with tetrazolium dye for LD activity.

Giant pigmented nevus is a variety of congenital melanocytic nevi, and may be associated with various abnormalities, such as skeletal malformation, lipoma, vascular nevi, melanosis in the meninges, meningocele, and intracranial arteriovenous malformation. We report a case with congenital giant pigmented nevus and porencephaly. This association should be considered as the spectrum of neurocutaneous syndromes related to congenital giant pigmented nevus.

Sodium hypochlorite is commonly used as a household bleaching agent (for example, the Clorox brand). Sodium hypochlorite poisoning with ingestion of a bleaching agent is often observed in clinical practice.Current Concepts: Ingestion (intentional or accidental) is the most common route of exposure to household bleaching agents. Accidental ingestion of household bleaching agents is rarely clinically important. However, ingestion of a large amount of a dilute formulation or a high-concentration preparation of bleaching agents can result in severe and rarely fatal corrosive injury. Therefore, prompt supportive care is essential because a specific antidote is currently unavailable. Severe poisoning requires hospital admission. Emergency endoscopy and thoracic and abdominal computed tomography are warranted to aid with diagnosis and management of hypochlorite-induced corrosive injury in patients with severe poisoning, who develop clinical features suggestive of corrosive injury.Discussion and Conclusion: Intentional poisoning, which accounts for most cases of household bleaching agent poisonings in Korea, is likely to cause severe corrosive injuries. Therefore, it is necessary to gain deeper and accurate understanding of the clinical aspects and treatment of poisoning by household bleaching agents.

For the adequate intraarticular exposure in medial talar dome lesions, medial malleolar osteotomy is necessary in some cases. Many operative techniques including transverse, oblique, inverted V-shape, crescentic and step-cut osteotomies of the medial malleolus have been described previously. But their techniques have several problems such as nonunion, rotation and limited access to lesions. So we introduce the new reverse chevron medial malleolar osteotomy which provides excellent access to lesions, good stability and a broad cancellous surface for rapid healing.

OBJECTIVE: To compare the short-term effect and advantage of transforaminal epidural steroid injection (TFESI) performed using the Kambin's triangle and subpedicular approaches. METHOD: Forty-two patients with radicular pain from lumbar spinal stenosis were enrolled. Subjects were randomly assigned to one of two groups. All procedures were performed using C-arm KMC 950. The frequency of complications during the procedure and the effect of TFESI at 2 and 4 weeks after the procedure between the two groups were compared. Short-term outcomes were measured using a visual numeric scale (VNS) and a five-grade scale. Multiple logistic regression analyses were performed to evaluate the relationship between possible outcome predictors (Kambin's triangle or subpedicular approach, age, duration of symptoms and sex) and the therapeutic effect. RESULTS: VNS was improved 2 weeks after the injection and continued to improve until 4 weeks in both groups. There were no statistical differences in changes of VNS, effectiveness and contrast spread pattern between these two groups. No correlation was found between the other variables tested and therapeutic effect. Spinal nerve pricking occurred in five cases of the subpedicular and in none of the cases of the Kambin's triangle approach (p<0.05). CONCLUSION: The Kambin's triangle approach is as efficacious as the subpedicular approach for short-term effect and offers considerable advantages (i.e., less spinal nerve pricking during procedure). The Kambin's triangle approach maybe an alternative method for transforaminal epidural steroid injection in cases where needle tip positioning in the anterior epidural space is difficult.

PURPOSE: The objective was to determine the association between PaCO₂ and adverse cardiovascular events (ACVEs) in carbon monoxide (CO)-poisoned patients. METHODS: This retrospective study included 194 self-breathing patients after CO poisoning with an indication for hyperbaric oxygen therapy and available arterial blood gas analysis at presentation and 6 hours later. The baseline characteristics and clinical course during hospitalization were collected and compared. The mean PaCO₂ during the first 6 hours after presentation was calculated. RESULTS: The incidence rates of moderate (30 mmHg< PaCO₂<35 mmHg) or severe (PaCO₂≤30 mmHg) hypocapnia at presentation after acute CO poisoning were 40.7% and 26.8%, respectively. The mean PaCO₂ during the first 6 hours was 33 (31–36.7) mmHg.The incidence of ACVEs during hospitalization was 50.5%. A significant linear trend in the incidence of ACVEs was observed across the total ranges of PaCO₂ variables. In multivariate regression analysis, mean PaCO₂ was independently associated with ACVEs (OR 0.798 (95% CI 0.641–0.997)). CONCLUSION Mean PaCO₂ during the first 6 hours was associated with increased ACVEs. Given the high incidence of ACVEs and PaCO₂ derangement and the observed association between PaCO₂ and ACVEs, this study suggests that 1) PaCO₂ should be monitored at the acute stage to predict and/or prevent ACVEs; and 2) further study is needed to validate this result and investigate early manipulation of PaCO₂ as treatment.

Purpose: This study was performed to determine whether the T1 relaxation time of gadoxetic acid-enhanced liver MR imaging is useful for detecting and staging liver fibrosis in patients with chronic liver disease. Materials and Methods: One hundred and three patients with suspected focal liver lesion underwent MR imaging and Fibroscan. Fibroscan was chosen as the reference standard for classifying liver fibrosis. T1 relaxation times were acquired before (preT1), 20 minutes after (postT1) contrast administration, and reduction rate of T1 relaxation time (rrT1) on transverse 3D VIBE (volumetric interpolated breath-hold examination) sequence using 3T MR imaging. The optimal cut-off values for the fibrosis staging were determined with ROC analysis. Results: PreT1 and postT1 increased and rrT1 decreased constantly with increasing severity of liver fibrosis according to the METAVIR score (F0–F4). There were statistically significant differences between F2 and F3 in preT1 (F2, 836.0 ± 74.7 ms; F3, 888.6 ± 77.5 ms, p < 0.05) and between F3 and F4 in postT1 (F3, 309.0 ± 80.2 ms; F4, 406.6 ± 147.7 ms, p < 0.05) and rrT1 (F3, 65.4 ± 7.7%; F4, 57.3 ± 11.4%, p < 0.05). ROC analysis revealed that combination test (preT1 + postT1) was the best test for predicting liver fibrosis. Conclusion PreT1 and postT1 increased constantly with increasing severity of liver fibrosis. T1 mapping in gadoxetic acid-enhanced liver MR imaging could be a helpful complementary sequence to determine the liver fibrosis stage.
