Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

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)

It was learned in 1960 that pregnancy could cause respiratory and circulatory changes, and that severe labor pain could cause tachycardia and cardiac arrythmias. We have experienced successful anesthetic management for cessarean section of a full term pregnant woman with multiple premature ventricular contractions under spinal anesthesia. PVC's could be caused by systemic hyposia, hypokalemia, acidosis hypercapnia, hypocalcemia, regional myocardial ischemia, etc. We could not confirm the cause of this woman's PVCs, but we assume that either deterioration of the respiratory and cardiac changes or severe labor pain could be implicated.

STUDY DESIGN: Comparative study. OBJECTIVES: To compare the outcomes of unilateral TLIF, bilateral TLIF using Wiltse approach and bilateral TLIF using conventional midline approach. SUMMARY OF LITERATURE REVIEW: There are many studies about outcomes of Unilateral TLIF, but few have compared the 3 different fusion procedures. MATERIALS AND METHODS: 60 patients were divided into 3 groups. Each group has enrolled 20 patients (Study group: unilateral TLIF, Control group 1: bilateral TLIF using Wiltse approach, Control group 2: bilateral TLIF using conventional midline approach). For clinical outcomes, we compared operative time, blood loss, time for ambulation and discharge, VAS for back pain and leg pain and ODI among three groups. For radiologic evaluation, disc height and segmental lordosis were examined. RESULTS: The mean operative time was 147 minutes in study group(SG), 172 minutes in control group 1(CG1), 167 minutes in control group 2(CG2). The mean total blood loss was 466ml in SG, 569ml in CG1, 1140ml in CG2 respectively. VAS for back pain at the third postoperative day significantly decreased in SG and CG1 compared with CG2. There was no significant difference in ODI, disc height and segmental lordosis among the groups. CONCLUSION: Using Wiltse approach, there were several advantages in decreasing blood loss, immediate postoperative back pain, hospital stay and early ambulation. Clinical and radiological results of unilateral TLIF were comparable with bilateral TLIF.
