Measurement of the bulbocavernosus reflex is widely used to diagnose underlying neurologic disorders in erectile dysfunction. Because this single parameter of latency time in BCRL(bulbocavernosus reflex latency) testing has been used as the sole guideline to diagnose neurogenic impotence, problems in discriminating neurological disturbance from nonneurogenic impotence are frequently encountered especially when the value of latency time is within the borderline range, or when the outcome is difficult to interpret. In order to assess the useful parameters of conventional BCRL testing for the differential diagnosis of neurogenic impotence, we performed BCRL testing in 100 patients who compliance of poor erection. We compared these patients with a previously controlled group of 45 adult males without any erectile or neuronal disturbance. The results obtained were summarized as follows. . 1)Of 100 patients, 24 were diagnosed as neurogenic impotence. 2) In this neurogenic impotence group, as compared to the normal and non-neurogenic impotence group, there was a significant difference(P<0.05) in the values of sensory, pain, reflex threshold and bulbocavernosus reflex latency time. 3) The BCR measurement allowed to find lateralized neurologic disturbance. These results show that in BCRL testing the evaluated values of sensory, pain and reflex threshold, in addition to latency time, can be useful parameters for the differential diagnosis of neurogenic impotence.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to sahage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coll, successfully managed with unilateral nephrectomy.

Central nervous system cryptococcosis is common in the AIDS patients with reported incidences ranging from 1.9% to 11.0%. Cryptococcosis may be the initial manifestation of HIV infection or occur simultaneously with other opportunistic infections. HIV-infected patients with central nervous system cryptococcosis complain of fever, headache, nausea and vomiting, and cognitive dysfunction. Meningeal signs and photophobia are less common than in HIV-negative patients. Focal neurologic signs and seizures are uncommon. Disseminated cryptococcosis is often concomitantly found at the time of central nervous system cryptococcosis. We report a case of 49 year-old Korean female with HIV infection who died of disseminated cryptococcosis with autopsy findings.

BACKGROUND/AIMS: Hepatocytes on the hepatic lobule mipate from portal zone to centrilobular mea as the DNA synthesis within it. And also, the xenobiotic reactions reveal characteristic differences associated with zone specific metabolism in the liver acinus. In this study, the zonal distribution of ethylnitrosourea (ENU)-induced hepatic precancerous lesion was stereologically investigated. METHODS: Nine B6C3F1 mices were given I.p. injection of ENU (60 ug/pn body weight) when the pups were 15 days old prior to sacrifices at 8 weeks of life. All the 150 consecutive sections, 3 p m in thickness, were stained with hematoxylin and eosin and identified the basophilic precancerous lesions with 80-165 p m diameter in equatorial plane by the Zeiss microprojector. And then the distances from the center of selected foci to terminal hepatic vein or portal vein branches were estimated under the microscopic fields. As a control group, the same estimations were performed from the random points by the appointments of random digit table. RESULTS: Mean distance between ENU-induced 52 hepatocellular foci and the nearest terminal hepytic vein was 181.15+112.39 p m (Mean+ SD), but that of randomly selected 104 points was 291.73+157.98pm (Mean+5D) (Students t-test, p<0.0005). Substantially, 52.7% of ENU-induced 52 hepatocellular foci were within 300 p m from the terminal hepatic vein, but randomly selected 104 points were only 50.9% (Shapiro Wilk W test, w=0.819857, p=0.048038). Mean distance from ENU-induced 52 foci to portal vein was 398.85+149.98pm (Mean+SD), but that from the randomly selected 104 points was 315.87+145.79 pm (Mean+SD)(Students t-test, p<0.0005). CONCLUSION: Stereologically, ENU-induced mice liver cell foci distribute non-randomly to Zone III, centrilobular zone of mouse hepatic acini where promote invasion toward terminal hepatic veins.

Skeletal muscles are known to have tolerance to ischemia, but a prolonged ischemia can cause damage to muscular tissues. The ischemia-reperfusion injury results from the oxygen free radicals released by leucocytes and formed by the reaction of hypoxanthine and xanthine oxidase. Superoxide dismutase (SOD), one of major antioxidant enzymes ocurring in the various tissues of the body metabolizes or scarvanges the oxygen free radicals. Although many studies reported difference in tolerance to ischemia and reperfusion between white and red muscles, some other investigators failed in finding such difference. The present study was performed to examine effects of graded periods of ischemia and reperfusion on the cellular ultrastructure and activity of SOD in white and red muscles. The Sprague-Dawley rats (200~250 g) were used as experimental animals. Under pentobarbital (50 mg/kg IP) anesthesia, incision was made on lower abdomen and left common iliac artery was occluded by means of a vascular clamp for 2, 4 and 6 hour (hrs). Thereafter, the superficial portion of mid-belly of anterior tibial muscle and soleus muscles were excised at 0, 24 and 72 hrs after onset of reperfusion. The specimens were sectioned into slices, 2 mm in length, 1 mm in width and thickness. Some specimens were prepared for electron microscopic observation and others for determination of SOD activity by using antihuman Cu, Zn- and Mn-SOD antibodies. The results obtained were as follows. 1. In anterior tibial muscle, areas with loose electron-density and dilated cristae were observed in the mitochondria immediately after 2 hrs of ischemia, while widened intermyofibrillar spaces and dilated cisternae of sarcoplasmic reticulum were seen after 2 hrs and 24 hrs reperfusion. When subjected to 2 hrs ischemia and 72 hrs reperfusion, no significant change was found in the cellular ultrastructure. 2. In soleus muscle, electron density was loose in the matrix of mitochondria immediately after 2 hrs of ischemia, while cisternae of sarcoplasmic reticulum were dilalated after 2 hrs of ischemia and 24 hrs reperfusion. Following 2 hrs of ischemia and 72 hrs reperfusion, the electron microscopic findings were similar to those of normal rats. 3. The changes in cellular ultrastructure were more prominent in both the 4 hrs and 6 hrs ischemia groups, in which degree of ultrastructural changes were proportional to duration of reperfusion. 4. In anterior tibial muscle, trace or weak immunoreactivities of Cu, Zn- and Mn-SOD were seen, whereas trace immunoreactivity of Cu, Zn-SOD and trace or weak immunoreactivity of Mn-SOD were observed in soleus muscle. 5. The immunoreactivities of Cu, Zn- and Mn-SOD were not altered in 2 hrs ischemic and 72 hrs reperfused group, while they were increased slightly in 2 hrs ischemic and 24 hrs reperfused group. 6. In both muscles, the activity of SOD increased following 4 hrs or 6 hrs ischemia and 24 hrs or 72 hrs reperfusion. The changes in immunoreactivity of Mn-SOD were not different between two muscles, whereas immunoreactivity of Cu, Zn-SOD were higher in anterior tibial muscle. Consequently, it is suggested that significant ischemia reperfusion injuries are produced after 4~6 hrs ishemia followed by 24 hrs or 72 hrs reperfusion, that anterior tibial muscle is more susceptible to ischemic reperfusion injury and that the ischemic-reperfusion injury is closely related with activity of SOD.

OBJECTIVE: Delirium is defined as an alteration in mental status characterized by brief disturbances in consciousness and attention, cognition, and perception that tend to fluctuate during the course of the day. Traditionally, haloperidol has been used to treat agitation as it may occur in delirium. However, atypical antipsychotics are increasingly used to treat delirium itself. A comparative study was undertaken to compare the clinical efficacy of haloperidol and aripiprazole for the treatment of delirium. METHODS: Forty patients (20 patients assigned to haloperidol and 20 to aripiprazole) diagnosed with delirium by DSM IV-TR were recruited and randomly assigned to receive a flexible-dose regimen of haloperidol or aripiprazole over 7 days. The severity of delirium was assessed by using the Delirium Rating Scale-Revised-98 scores (DRS-R-98). RESULTS: DRS-R-98 severity scores for each group decreased significantly over the study period (p<0.01), but no statistically significant difference was detected between the two groups (p=0.607). CONCLUSION: These data show no statistically significant difference in efficacy between haloperidol and aripiprazole in the treatment of delirium. Since haloperidol has great potential for causing extrapyramidal symptoms(EPS), aripiprazole, a medication with known low side effects, may be an effective alternative agent in the treatment of delirium.

The malignant peripheral nerve sheath tumor (MPNST) originates from neurofibromatosis type 1 (NF1). Because NF1 patients have many accompaniments with growth of additional masses, they usually overlook potential malignant changes in their masses. Our patient had two growing mass near the left elbow for several months; however, she ignored these masses until 7 days prior to writing this article, at which time they began bleeding. Traditionally, sarcoma including MPNST treatment consisted of amputation of the involved extremity. However, treatment now consists of surgical resection with adjuvant therapy. Therefore, we conducted resection of the mass and subsequent coverage with a local advancement flap. We believe that the most effective treatment for MPNST is early diagnosis and fast surgery, coupled with notification that there is always potential for malignant change in NF1 patient's masses.

Anisakis is a parasite with life cycles involving fish and marine mammals. Human infection, anisakiasis, occurs with the ingestion of raw infected seafood and usually presents with acute or chronic gastrointestinal symptoms from esophageal or gastric invasion. We report a rare caseinvolving the oral cavity. A 39-year-old male presented with oral and sub-sternal pain of one day duration after eating raw cuttlefish. Physical examination revealed areas of erythema and edema with a central white foreign particle on the labial and buccal mucosa. With microscopic field we could remove the foreign material from the lesions. The foreign material was confirmed to be Anisakis. Anisakis was also removed from the esophagus by esophagogastroduodenoscopy. The patient was discharged the following day without complication. Anisakiasis is frequently reported in Korea and Japan, countries where raw seafood ingestion is popular. The symptoms of acute anisakiasis include pain, nausea, and vomiting and usually begin 2–12 hours after ingestion. The differential diagnosis includes food poisoning, acute gastritis, and acute pancreatitis. A history of raw seafood ingestion is important to the diagnosis of anisakiasis. Treatment is complete removal of the Anisakis to relieve acute symptoms and prevent chronic granulomatous inflammation.
