Mesenteric fibromatoses occur as sporadic lesions or as parts of familial adenomatous polyposis, are clonal lesions prone to locally aggressive behavior, but lack metastatic capacity. Fibromatoses harbor somatic beta-catenin or adenomatous polyposis coli (APC) mutations, leading to intranuclear accumulation of b-catenin. We report a case of mesenteric fibromatosis presenting as a 5.4x4.8 cm submucosal tumor of the jejunum in a 42-year-old woman. Histologically, the tumor consisted of proliferation of bland, elongated-spindle fibroblasts with collagen deposition and a characteristic prominent vasculature. Immunohistochemically, the tumor cells showed nuclear staining for beta-catenin. Mesenteric fibromatosis should be included in the differential diagnosis of submucosal spindle cell tumors of the gastrointestinal tract, and nuclear immunoreactivity for beta-catenin may help distinguish these tumors form histological mimics.

Activation of the sympathetic nervous system in mediating the stress response attends traumatic brain injury. Plasma dopamine(DA), epinephrine(E), norepinephrine(NE) levels were measured in 26 severe traumatically brain injured patients to determine whether catecholamine levels obtained within 24 hours after injury provide reliable prognostic endogenous markers of outcome. Patient outcome was determine at 1 week using the Glasgow Coma Scale(GCS) and at the time of discharge the Glasgow Outcome Scale(GOS), 7 patients with diseases except those with a severe traumatic brain injury were selected as a control group. Firstly, we analyzed the difference of the average DA, E, and NE between the control group and severe traumatic brain injury patients. Secondly, we analyzed the difference of the average catecholamine levels in the 3 groups according to admission GCS scores(respectively 3~4, 5~7, 8~9). Third, we analyzed the difference of the average catecholamine levels in the 5 groups according to GOS scores at 1 week(respectively dead, 3~4, 5~7, 8~11, >11). Finally, we analyzed the difference of the average catecholamine levels in the 5 groups according to GOS at the time of discharge. As a result, there was no statical difference between the level of DA in the control group and those of the severe brain injury patients. But the level of E an NE in the experimental group were higher than the control group(respectively p<0.03, p<0.04). The admission GCS score correlated highly with the catecholamine levels(NE : r=0.69, p<0.001 ; E ; r=0.42, p<0.03 ; DA ; r=0.42, p<0.03). In patients with admission GCS of 3 to 4, NE levels increaed fourfold above other group(p<0.005). In the 13 patients with GCS scores of 3 or 4 on admission. NE levels predicted outcome at 1 week. All two patients with NE levels less then 750 pg/ml were survived, while 10 of 11 with NE levels greater than 750 pg/ml were died(p<0.02). The levels of NE was significantly higher in patients who died than in those with better outcome(p<0.02). Therefore, these findings indicated that the level of circulating NE is an excellent endogenous marker that appear to reflect the extent of brain injury and that may predict the likelihood of recovery.

During the eleven months from September, 1989 to July, 1990, a total of 118 subarachnoid hemorrhage(SAH) patients were admitted. Among these, in 2 cases, the etiology was unknown and another 8 cases of Hunt & Hess clinical grade V patients died in the emergency room or intensive care unit within 24 hours after admission. The remaning 108 cases were managed with protocol as follows. 1) Surgery was done within 9 days after the SAH(total 67 cases) : Extraventricular drainage(EVD) was performed and a cisternal drainage(CD) catheter was positioned during surgery. EVD, CD nimodipine irrigation(0.4mg) through the CD catheter, and intravenous injection(IV) of nimodipine(1~2mg/hr)continued for 13days after the SAH. 2) Surgery was done after the 9th SAH day due to late transfer neurology or other hospitals or posterior circulation aneurysms(32 cases), and 9 cases refused surgery : Nimodipine was used orally(240mg/day) in 35 cases and an IV route(1~2mg/hr) in 6 cases. Total management outcome and results were obtained as follows. 1) A total unsatisfactory management outcome was 18.52%(serve disabled : 4.63%, vegetative : 0.93%, death : 12.96%. In the surgical cases only, 40.8%, 1.02%, 9.19%, respectively). 2) An unsatisfactory surgical outcome in cases following surgery after the 9th SAH day was 6.24%(severe disabled : 3.12%, death : 3.12%). 3) An unsatisfactory management outcome in cases of admission grades I & II following surgery within the 9th SAH day or those non-surgical patients was 19.15%(severe disabled : 4.25%, death : 14.89%. In surgical cases only 2.33%, 9.30%, respectively). 4) An unsatisfactory management outcome in cases of admission grades III & IV with surgery within the 9th SAH day or non-surgical patients was 29.63%(severe disabled : 7.41%, vegetative : 3.70%. death : 18.52%. In surgical cases only 9.09%, 4.55%, 13.64%, respectively). One case of admission grade V died. 5) Causes of unsatisfactory outcome were vasospasm : 9 cases(8.33%), SAH itself : 4 cases, rebleeding : 3 cases, surgical complication : 1 case, medical complication : 1 case, anesthesia : 1 case, and head trauma : 1 case. 6) Complications in management protocol with EVD, CD, CD nimodipine irrigation, and IV of nimodipine were transient hypotension(1 case) and meningitis(5 cases). These complications were improved without sequelae with discontinuing the IV of nimodipine and using antibiotics. We concluded that this protocol may improved the total management outcome of aneurysmal SAH patients, especially poor grade patients(Hunt & Hess grade III & IV) without significant complications. However, in spite of this protocol, the leading cause of an unsatisfactory outcome is vasospasm.

PURPOSE: In this study, we compared the quantitative characteristics of dynamic salivary gland scintigraphy with static scintigraphy in patients with clinical sicca syndrome using Tc-99m pertechnetate. MATERIALS AND METHODS: Fifty-two parotid glands and 52 submandibular glands out of 26 patients with clinical sicca syndrome were studied by dynamic and static salivary gland scintigraphy. Ten normal volunteers were also studied as a control group for comparison of scintigraphic parameters. Ten minutes after injection of 370 MBq Tc-99m pertechnetate, we obtained pre-stimulus static images for a few minutes. Then dynamic salivary gland scintigraphy with lemon juice stimulation was performed for 20 minutes. Finally we obtained post-stimulus static images after dynamic images. On dynamic study, functional parameters such as uptake rate, secretion rate and re-uptake rate were calculated. The results of dynamic study and static images were compared. RESULTS: On dynamic study, we could obtain functional parameters of salivary glands successfully. On dynamic study, 22 parotid glands and 22 submandibular glands out of each of 52 glands are abnormal. The static images demonstrated somewhat different results, of which reasons we could assume via dynamic study. CONCLUSION: Dynamic salivary gland scintigraphy using Tc-99m perechnetate were more functional than static images and might be useful in the assessment of the functional change of the salivary gland in patients with clinical sicca syndrome.

Purpose: To report a case with corneal decompensation in a patient of pseudoexfoliation syndrome.Case summary: A 70-year-old woman was referred to our clinic to evaluate decreased visual acuity in the right eye. She had no history of previous ocular surgery or laser treatment. The best corrected visual acuity was 0.5 in both eyes. The patient had diffuse corneal edema in the epithelium and stroma in the right eye. The left eye showed diffuse endothelial pigment deposits. Deposition of pseudoexfoliation material on the iris and anterior lens capsule was observed in both eyes. The intraocular pressure was 15 mmHg in both eyes without treatment. Specular microscopy was limited in the right eye due to the corneal edema and the left eye showed endothelial cell loss, increased pleomorphism, and atypical guttata. Anterior segment optical coherence tomography revealed irregular thickening of the corneal stroma and protrusion of Descemet’s membrane in the right eye. Conclusions In patients with pseudoexfoliation syndrome, corneal decompensation can occur without intraocular pressure elevation and glaucomatous damage.

We report a case of a 23-year-old female immigrant from China who was diagnosed with multidrug-resistant tuberculosis affecting her lung and brain, resistant to the standard first-line therapeutics and streptomycin. She was treated with prothionamide, moxifloxacin, cycloserine, and kanamycin. However, her headache and brain lesion worsened. After the brain biopsy, the patient was confirmed with intracranial tuberculoma. Linezolid was added to intensify the treatment regimen, and steroid was added for the possibility of paradoxical response. Kanamycin was discontinued 6 months after initiation of the treatment; she was treated for 18 months with susceptible drugs and completely recovered. To our knowledge, this case is the first multidrug-resistant tuberculosis that disseminated to the brain in Korea.

Gastric metastasis from ovarian cancer is rarely reported worldwide. In Korea, only 2 such cases have been reported. Here we report a case of a 58-year-old woman with metastatic gastric cancer from an ovarian adenocarcinoma. Endoscopic examination showed that the cancer presented as a submucosal tumor without ulceration. A subsequent gastrectomy confirmed the diagnosis of metastatic ovarian serous adenocarcinoma.

Necrotizing pneumonia causes necrosis of pulmonary parenchyma and may lead to pulmonary gangrene. Prior to theantibiotic era, extensive pulmonary involvement was potentially fatal, but the incidence of necrotizing pneumoniais now less common. On contrast-enhanced CT scans, consolidation with contrast enhancement containing necroticfoci with low attenuation and cavities is characteristic. Radiologic findings do not differ according to thecausative organism and in most of cases, specific diagnosis may be impossible. Clinical findings and certaincharacteristic radiologic findings may be helpful for narrowing the differential diagnosis. We illustrate theclinical and radiologic characteristics of necrotizing pneumonia according to causative bacterial organisms.
