Strong corrosive acid is accidentally ingested by children or by psychiatric patients for the purpose of suicidal attempt. Late complications include chemical burn to pharyunx, perforation and stricture of upper gastrointestinal tract, respiratory insufficiencyand renal failure caused by hemoglobinuria following hemolysis. Acetic acid is difficult to ingestion large volume in a time because it is a strong irritant, provocating painful pharynx, and its autopsy case is rare. We report an autopsy case of acetic acid intoxication with acute disseminated intravascular coagulation (DIC) in several hours. We present pathogenesis of acetic acid intoxication and the associated forensic problems. A comatous 39-year-old female was admitted to emergency room 6 hours after she swallowed 90 gm of acetic acid. She was treated with gastric lavage but she was expired 9 hours after swallowing acetic acid. She was consulted to Department of Forensic Medicine of Kyungpook National University School of Medicine. She was grossly icteric and livor mortis was generally dark red. External wounds were 10 hemorrhagic lesions with 5 x 3.7cm and 3 x 2.8cm on the left arm and hand dorsum and facial abrasions. Internal gross examination revealed several purpural lesions in the gastric serosal surface and greater omentum. Microscopically, the stomach showed diffuse mucosal coagulation necrosis and intravascular hyalinized or fibrinoid thrombi in submucosal blood vessels. Liver showed necrosis of periportal area (zone I) and intracellular cholestasis around the central vein. Sections from renal tissue frequently show hemoglobin casts in the tubules and RBCs in the Bowman's capsules. Acetic acid of a remnant bottle, sampled blood and bloody necrotic tissues in the stomach were toxicologically examined in National Science Laboratory. The purity of ingested acetic acid is 98%, the concentration of acetic acid ion in blood is 734ppm and the content in gastric juice is 0.09%. In patients after acetic acid ingestion, DIC is most probably caused by procoagulants, produced by extensive acid-induced necrosis of the upper gastrointestinal tract. In this case, several purpural lesions were revealed on the arm, around facial abrasion and intravenous injection sites of the wrists. These are important to differentiate with contusion because she was battered before acetic acid ingestion. Purpurae in DIC are poorly demarcated, dark purple elevations with spreading margin but subcutaneous hemorrhage in contusion is grayish black or dark red with well demarcation (Table 2). But careful examination should be considered because traumatic hemorrhage is also exaggerated and mixed in DIC. (The Korean Journal of Legal Medicine)

Blunt chest trauma may cause a variety of cardiac injuries, such as cardiac contusion, congestive heart failure due to myocardial injury or disruption of intracardiac structures, and more severely, instantaneous death. Traumatic rupture of the interventricular septum secondary to blunt chest trauma is extremely rare. Rupture of the interventricular septum may occur almost immediately after injury or many days later. The most common site of rupture is in the muscular portion of the septum near the apex. The exact mechanism of ventricular septal rupture in blunt trauma is unknown but it is thought to occur by external compression of the heart between the sternum and the vertebrae or as a result of extreme changes in intrathoracic pressure during sudden deceleration. We report an autopsy case of intraventricular septum rupture due to blunt chest trauma. A comatous 28-year-old male was admitted to emergency room after blunt chest trauma by unidentified object. He was treated with supportive care but expired two days later. The autopsy findings were as follows. The dead boy was slightly slender. External wound and patterned bruise were not present. In submentopubic incision, both pleural fluid (right 700ml, left 450ml) and ascites (400ml) were noted. The posterior wall of left ventricle showed hemorrhage measuring 1cm in diameter. On opening the heart, there was interventricular septum rupture measuring 3.5cm in length. Other cardiac structures were unremarkable. On light microscopic examination, endothelial cell was not seen in ruptured portion and both lung showed severe congestion and edema.

OBJECTIVES: The region of chromosome 5p14 is known to be associated with autism spectrum disorder (ASD). The cadherin9 (CDH9) and cadherin10 (CDH10) genes are located in the region of chromosome 5p14 and reported to be associated with ASD in the Caucasian population. We performed an association study to identify if single nucleotide polymorphisms (SNPs) located on the CDH9 and CDH10 genes are associated in the Korean population. METHODS: Genomic DNA was extracted from the blood of 214 patients with ASD and 258 controls. SNPs selected from two genes were genotyped using an Illumina Golden-Gate Genotyping assay with VeraCode technology. Statistical analysis was performed using SAS and Plink software. RESULTS: All controls and ASD patients were in Hardy-Weinberg equilibrium. In the results of logistic regression analyses for the genotype model and the chi-square test for the allele model, we found that SNPs on the CDH9 and CDH10 genes were not associated with ASD. CONCLUSION: Our data suggests that the CDH9 and CDH10 genes are not associated with ASD in the Korean population.

OBJECTIVES: Urocanase domain containing 1 (UROC1) has never been studied in prior studies on autism spectrum disorders (ASDs). UROC1 causes urocanic aciduria, one of the symptoms of which is mental retardation. The aim of this study was to investigate the association between the UROC1 gene and ASDs in a Korean population. METHODS: A total of 258 control and 214 patients with ASD were used as subjects of this study. SNPs selected from UROC1 were genotyped using Illumina Golden-Gate Genotyping assay with VeraCode(R) technology. Statistical analysis was performed using SAS and Plink software. RESULTS: We found no association of the 12 SNPs in the UROC1 gene with ASDs in a Korean population. CONCLUSION: Our study suggests that the 12 SNPs (11 SNPs and 1 SNP in the intron and 3'UTR region, respectively) in the UROC1 were not associated with ASDs in a Korean population. Further study on the exon region of UROC1 is needed.
