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)

A 38-year-old nulliparous woman was referred to our clinic because of cervical incompetence at 19 weeks of gestation. Trans-abdominal cervicoisthmic cerclage was performed after failure of modified Shirodkar cerclage operation in the patient at 21 weeks of gestation via a laparotomic approach. Another 38-year-old patient, who underwent loop electrosurgical excision procedure conization for treatment of cervical dysplasia 4 years ago, presented for cervical incompetence. At 18 weeks of gestation, we performed trans-abdominal laparotomic cervicoisthmic cerclage without any post-operative complications. During antenatal follow-up, there were no obstetrical co-morbidities and finally she gave birth to a healthy infant at full term by cesarean section. We report two cases of women who underwent trans-abdominal cervicoisthmic cerclage surgery because of cervical incompetence as they were not suitable for transvaginal cervical cerclage. Both patients successfully maintained their pregnancy until full term after undergoing transabdominal cervicoisthmic cerclage at more than 18 weeks of gestation.

PURPOSE: Epidormoid cysts are benign epithelial cysts often ocurring within the skin of face and trunk. But carcinomatous change is rare. The authors experienced a case of squamous cell carcinoma arising from the wall of epidermoid cyst of axilla and report the radiologic and pathologic findings with a brief review of the literatures. METHODS AND MATERIALS: Plain chest radiograph, US and enhanced CT of axilla were takened. We analyzed radiologic findings of squamous cell carcinoma in the wall of epidermoid cyst of axilla and correlated with pathologic findings. RESULTS: Plain chest radiograph revealed a huge axiilary mass without bony destruction or calcification. showed a heterogenous hyperechoic mass with eccentrical cystic lesion. Outer margin of the mass was irregular. No posterior acoustic enhancement was seen. Postcontrast CT scan showed a circumscribed complex mass with irregular enhancing rim. During operation mass was located within subcutaneous layer and internal contents of the mass were brown, necrotic keratinous debries. CONCLUSION: Differentiation from solid tumor was difficult. But intradermal or subcutaneous location and rapid growing were characteristic.

PURPOSE: The usefulness and radiographic findings of the angiography in cerebral infarction are well known. We attempted to evaluate the anglographic causes, findings, and the usefulness of DSA in cerebral infarction. MATERIALS AND METHODS: The authors reviewed retrospectively DSA images of 51 patients who were diagnosed as having cerebral infarction by brain CT and/or MRI and clinical settings. DSA was performed in all 51 patients, and in 3 patients, conventional anglogram was also done. Both carotid DSA images were obtained in AP, lateral, oblique projections, and one or both vertebral DSA images in AP and lateral. The authors reviewed the patient's charts for symptoms, operative findings and final diagnosis, and analysed DSA findings of cerebral atherosclerosis with focus on 6 major cerebral arteries. RESULTS: Among the 51 patients of cerebral infarction 43 patients(84.3%) had cerebral atherosclerosis, 1 dissecting aneurysm, 1 moyamoya disease and 6 negative in anglogram. DSA findings of cerebral atherosclerosis were multiple narrowings in 42 patients(97,7%), tortuosity in 22(51.2%), dilatation in 14, occlusion in 12, avascular region in 8, collaterals in 7, ulcer in 6, and delayed washout of contrast media in 3. In cerebral atherosclerosis, internal carotid artery was involved in 37 patients(86.0%), middle cerebral artery in 29(67.4%), posterior cerebral artery in 28, anterior cerebral artery in 26, vertebral artery in 22, and basilar artery in 15. Intracranial involvement of cerebral atherosclerosis (64.9%) was more common than extracranial involvement(16.2%). CONCLUSION: In cerebral infarction MRA may be the screening test, but for more precise evaluation of vascular abnormality and its extent, DSA should be considered.

There are few methods to control heavy intra-operative bleeding during cesarean delivery of placenta previa. Transient occlusion of uterine arteries (TOUA) during operation has previously been reported as a quick and safe method to control intra-operative uterine bleeding. We reported 2 cases of cesarean delivery with complete placenta previa in which TOUA was performed to safely reduce intra-operative complication, especially heavy intra-operative bleeding. In the 2 cases, cesarean deliveries were safe and without any complications under the TOUA method. TOUA can be a good method to control heavy intra-operative bleeding during cesarean delivery of complete placenta previa with risk of heavy bleeding.

The technetium (Tc)-99m pyrophosphate scans have been used to diagnose acute myocardial infarctions and to confirm the equivocal cases. Many articles have been reported about its diagnostic performance and pitfalls. But there has been no evaluation of its predictability according to the grades of the radioactivity land statistical evaluation of the trade-off point, i.e., grade 2 and the area under the receiver operating characteristic curve. To achieve the goals, we reviewed 252 cases of Tc-99m pyrophosphate scans (acute transmural infarction [n=99], acute subendocardial infarction [n=7], unstable angina[n=16], old myocardial infarction [n=19] others [n=111]). The predictabilities of the scan are 98% in grade 4, 84% in grade 3, 83% in grade 2, 53% in grade 1 and 18% in non-uptake. The usual trade-off point, grade 2 is not statistically significant(Z=1.945, P=0.0259>0.01). The area under the receiver operating characteristic curve(Az) is 0.885. Our study shows that the probable main cause of the false negative cases is the time interval between the onset of symptoms and the test.

A 39-year-old nulliparous woman experienced continuous mild fever and abdominal pain since undergoing laparoscopic ovarian dermoid cystectomy 3 months previously in a local hospital. Abdominal computed tomography revealed diffuse heterogeneous fat infiltrations with numerous micronodules in the greater and lesser omentum, combined with ascites with thickening of the parietal peritoneum. The patient underwent exploratory laparoscopy, which included partial pelvic peritonectomy, excision of granulomas, and adhesiolysis with massive irrigation. The patient was treated successfully with laparoscopic surgery and all reproductive structures were spared without operative complications. To avoid peritonitis, complete removal of cyst contents and massive irrigation should be performed during ovarian dermoid cystectomy. Conservative surgical treatment may be a good choice for treating granulomatous peritonitis induced by iatrogenic rupture.
