Mycoplasma pneumoniae is responsible for approximately 20% to 30% of community-acquired pneumonia, and is well known for its diverse extrapulmonary manifestations. However, acute necrotizing pancreatits is an extremely rare extrapulmonary manifestation of M. pneumoniae infection. A 6-year-old girl was admitted due to abdominal pain, vomiting, fever, and confused mentality. Acute necrotizing pancreatitis was diagnosed according to symptoms, laboratory test results, and abdominal computed tomography scans. M. pneumoniae infection was diagnosed by a 4-fold increase in antibodies to M. pneumoniae between acute and convalescent sera by particle agglutination antibody assay. No other etiologic factors or pathogens were detected. Despite the occurrence of a large infected pseudocyst during the course, the patient was able to discharge without morbidity by early aggressive supportive care. This is the first case in Korea of a child with acute necrotizing pancreatitis associated with M. pneumoniae infection.

Computed tomography (CT) is considered as gold standard in evaluating pancreatitis in human, but there have been only a few studies in veterinary field. Balthazar CT severity index (CTSI) used to assess the severity of acute necrotizing pancreatitis in human could be applicable to dogs, because the severity of acute pancreatitis depends on the area of pancreatic necrosis in dogs more than in human. In this study, 25 adult, clinically healthy beagle dogs were used. CT examinations was performed in normal pancreas, positive control group and acute necrotizing pancreatitis induced by autologous bile injection. Balthazar CTSI was applied to canine acute necrotizing pancreatitis in contrastenhanced CT image and compared with the result of histopathologic examination. The Hounsfield unit (HU) of normal canine pancreas was $52.44{\pm}4.58$ and the density was significantly decreased in acute necrotizing pancreatitis (P < .05). In contrast-enhanced CT examination, pancreatic density was decreased significantly and this area was compatible to pancreatic necrosis. Balthazar CTSI showed positive correlation with histopathologic evaluation with a sensitivity of 100% and a specificity of 88.89%. Balthazar CTSI can be applied to evaluate the severity of acute necrotizing pancreatitis in dogs.

The formation of aortic thrombi is an extremely rare complication of acute pancreatitis. Here we report a case of acute pancreatitis complicated by a paraesophageal pseudocyst, necrotizing mediastinitis, and the formation of multiple thrombi in the ascending aorta. The patient was successfully treated by surgical therapy, which included extensive debridement of the mediastinum and removal of the aortic thrombi under cardiopulmonary bypass. Although esophageal resection was not carried out concomitantly, the lesions were resolved and the patient remained free of complications over 2 years of follow-up care.

Acute necrotizing encephalopathy (ANE) may be suspected when a young child presents with abrupt onset of altered mental status, seizures, or both. Definitive clinical diagnosis is based on magnetic resonance imaging (MRI) results. ANE is associated with influenza virus infections. Preliminary data suggests that up to 25% of ANE patients die, and up to 25% of ANE survivors develop substantial neurologic sequelae. Here, we describe a case of a comatose 22-month-old girl who was admitted to our hospital because of febrile illness and seizures. On day 13 of her illness, she died from ANE associated with infection from parainfluenza virus. Brain MRI results indicated diffuse bilateral symmetric signal changes in both basal ganglia, thalami, periventricular white matter, pons, and cerebral white matter, as well as generalized swelling of the brain.

A 13-month-old intact female poodle dog presented with an acute history of circling and seizure episodes. On the basis of the results of neurologic examination combined with magnetic resonance imaging and cerebrospinal fluid analysis (CSF), meningoencephalitis of unknown etiology (MUE) was suspected. Therapy with mycophenolate mofetil plus prednisolone was initiated, following which the clinical signs showed improvement for only one month before gradually worsening again. Acute progression of the clinical disease was observed, and the patient was euthanized 91 days after initial presentation. This case was definitively diagnosed as necrotizing meningoencephalitis (NME) according to the results of post-mortem histopathological examination. This report describes the clinical findings, serial magnetic resonance imaging (MRI) characteristics, and histopathological changes in a case of acute NME.

Necrotizing periodontal diseases, especially acute necrotizing ulcerative gingivitis (ANUG), it should be noted, occur abruptly and progress rapidly, eventually causing severe soft-tissue and alveolar bone loss. This report presents the cases of two ANUG patients and provides a brief treatment protocol for easy and effective clinical management. After proper diagnosis, sequential treatment with cessation of mechanical brushing, along with a prescription of systemic antibiotics and chlorhexidine as a mouth rinse, scaling, root planing, and supportive periodontal therapy, was utilized. In all cases discussed in this report, there was marked improvement in a few days. ANUG, though an uncommon disease, can be efficiently managed with proper diagnosis and immediate treatment.

We present a case of a colonic involvement associated with necrotizing pancreatitis, with a review of the literature. A 10 year old boy had an appendectomy at the local clinic ten days ago. On admission, he complained nausea, vomiting and severe constipation. His abdomen was distended and he had tenderness on the left abdomen. Laboratory and radiologic studies revealed findings consistent with acute pancreatitis with colonic complication. He was treated conservatively for 30 days but did not improve. On hospital 30th day, abdominal pain developed and his vital sign changed. Abdominal CT suggested ischemic change of the transverse colon. At laparotomy, the left colon showed stenosis. The greatly distended transverse colon was resected and a transverse end colostomy was done. He was discharged at postoperative 45th day with improvement and colostomy closure was performed 8 months later.

Herpes simplex is caused by viruses of the herpesvirus hominus family. HSV have four categories: type 1, 2, 6, and 8. Generally HSV-1 affects the mouth. Once infected by HSV, the person's infection is permanent. Retrograde transport through adjacent neural tissue to sensory ganglia leads to a lifelong latent infection. Recently, we treated a patient with recurrent herpes-stomatitis mimicking acute necrotizing ulcerative gingivitis (ANUG). The results were satisfactorty so we report this case. 31 years old male patient showed sore throat, gingival ulceration, palpable both submandibular lymph node, and sulcular pus formation around posterior decayed teeth. This is the third time he has suffered from this symptom. Tentative diagnosis was acute necrotizing ulcerative gingivitis. Antibiotic therapy was started. But, intraoral symptom got worse in process of time. Especially ulcer of marginal gingiva got worse. Viral disease was suspected. We carried out viral cultivation. At the same time topical application of antiviral ointment (herpecid$^{(R)}$) was performed on oral ulcer unilaterally for the purpose of diagnosis and reducing pain experimentally. The next day pain was decreased dramatically on application area. Basing on the viral cultivation and clinical effect of antiviral ointment (herpecid$^{(R)}$), we have diagnosed it as a recurrent herpes-stomatitis and concluded that viral infection was major cause of disease and bacterial infection was secondary.

Necrotizing fasciitis is rare acute infection showing rapidly necrosis involve the subcutaneous tissue and fascia. If treatment is delayed, infection can spread to involve the subcutaneous tissue, skin, deep fascia, and even muscle in rapid sequence, resulting in widespread necrosis and moderate to severe systemic toxicity. Most commonly this disease presents in the extremities, trunk, and perineum; it is relatively rare in the head and neck regions. If not diagnosed and treated in its early stages, necrotizing fasciitis can be potentially fatal, with a motality rate approaching 40%. Historically, the clinical entity now referred to as necrotizing fasciitis was described in the literature under various name. : hospital gangrene, necrotizing erysipelas, streptococcal gangrene, suppurative fasciitis. Necrotizing fasciitis was first described by Wilson in 1952. We experienced 3 cases of necrotizing fasciitis and will report review of literature with diagnosis, treatment, complication and consideration.
