Abnormalities of body fluid and electrolyte balance, acute renal failure, nephrotic syndrome, interstitial nephritis and papillary necrosis are well known disease of wide spectrum of NSAID induced renal side effect. Many different mechanism such as inhibition of prostaglandin pathway, delayed hypersensitivity reaction and direct toxicity are reported to relate to development of disease. Recently, overuse of NSAID has steadily increased the cases of NSAID induced side effects and in some cases permanent damage to kidney has been reported. Authors experienced a 67-year-old male patient who presented with gross hematuria, edema and azotemia and diagnosed as interstitial nephritis accompanying nephrotic syndrome. Kidney biopsy shows the edema and the diffuse infiltration of lymphocytes in the interstitium. The glomerular changes suggest minimal change lesion or focal segmental glomerular sclerosis in early stage. The patient had continuously consumed piroxicam for 6 months and had improved after discontinuation of this drug as well as treatment with steroid but remained renal damage. This case suggest that piroxicam may be an agent that causes interstitial nephritis and nephrotic syndrome. Therefore clinician should use it with caution especially in patients with high risk factors.

BACKGROUND/AIMS: To describe the toxicity profile of anti-neoplastic agents from real clinical settings, we analyzed spontaneously reported adverse events (AEs) using data from the adverse drug reaction (ADR) reporting system of the Korean Food and Drug Administration (KFDA). METHODS: Data were extracted from the nationwide spontaneous ADR reporting system of KFDA from July 2009 to December 2010. We extracted and analyzed data related to chemotherapy and identified unlabeled ADR that were not described in the package insert of the products. RESULTS: In total, 5,867 cases of antineoplastic agent-related AE reports were identified after excluding cases for duplication and cases assessed as 'unlikely' and 'unclassifiable', based on expert opinion. Of the patients with AEs, 52.4% were males and the median age was 56 years. In total, 460 AEs (7.8%) from 267 patients were reported as 'serious' AEs. The most common causative anti-cancer drug class was pyrimidine analogs (31.5%), followed by platinum compounds (19.9%), protein kinase inhibitors (10.8%), and taxanes (8.8%). The most common clinical manifestation of AEs was gastrointestinal toxicities (25.5%), followed by skin disorders (25.3%), and generalized reactions (14.3%). In total, 168 cases (2.9%) of unlabeled AEs were identified. Among these, 10 were reported as serious AEs. CONCLUSIONS: The most common causative class of antineoplastic agents was that of pyrimidine analogs. Gastrointestinal and dermatological toxicities were the most common clinical chemotherapy-related adverse events. Further investigation and monitoring to evaluate causality associated with unlabeled AEs identified in this analysis are needed.

BACKGROUND: Clonidine has been regarded as an adequate supplementary anesthetic during epidural anesthesia and has been used with local anesthetics such as bupivacaine or lidocaine to support the effects of these anesthetics. The authors would examine whether clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural anesthesia. METHODS: Thirty-two healthy patients undergoing a hip or lower limb surgery were divided into two groups. In group 1, 0.5% ropivacaine 15 ml was administered. In group 2, 0.5% ropivacaine 15 ml combined with clonidine 150 micro gram was administered. Onset, duration and maximal height of sensory block were assessed. Sedation score, blood pressure and heart rate were measured. RESULTS: Duration of sensory block of group 2 was significantly longer than that of group 1. Sedation score of group 2 was significantly higher than that of group 1. Blood pressure of group 2 was significantly lower than that of group 1 at 50 min, 70 min and 90 min after epidural injection. No significant differences were observed in onset of sensory block and heart rate between the two groups. CONCLUSIONS: The addition of clonidine to ropivacaine during epidural anesthesia prolonged duration of sensory block and produced useful sedation. It caused relatively stable hemodynamic changes. These results suggest that clonidine is an adequate supplementary anesthetic when it is used with ropivacaine during epidural anesthesia.

BACKGROUND: Although spinal anesthesia has a lot of advantages, it has some disadvantages or undesirable effects. Hypotension and unnecessarily long neural blockade are included among them. Although using small dose local anesthetics fairly solves these problems, it is insufficient to provide reliable surgical anesthesia by itself. Therefore the authors investigated whether such an opioid as fentanyl and a small dose local anesthetic used together during spinal anesthesia can prevent hypotension and unnecessarily long neural blockade and provide reliable surgical anesthesia simultaneously. METHODS: Thirty patients undergoing knee or below knee surgery were randomized into two groups. Group 1 received bupivacaine 5 mg combined with fentanyl 20 micro gram, and group 2 received 10 mg bupivacaine. Hypotension was recorded and was treated with intravenous ephedrine. Sensory blockade, intraoperative analgesia, motor blockade and side effects were assessed. RESULTS: No significant differences were observed in values for assessing hypotension, sensory blockade or intraoperative analgesia between the two groups. Also no significant differences were observed in intensity of the motor blockade and side effects between the two groups. However the duration of the motor blockade of group 1 was longer significantly than that of group 2. CONCLUSIONS: Small dose bupivacaine and fentanyl administered together intrathecally reduced duration of motor blockade and didn't augment of side effects and provided reliable anesthesia for surgery of knee or below knee simultaneously.

PURPOSE: Traumatic head injury is very common in the emergency room. Early diagnosis and treatment can significantly reduce mortality and morbidity. When diagnosis is delayed, however, it could be critical to the patients. In reality, it is difficult to take a brain CT for all patients with head trauma, so this study examined the relationship between type and size of scalp injury and intracranial injury. METHODS: This prospective study was conducted from May 2005 to July 2005. The participants were 193 patients who had had a brain CT. Head trauma included obvious external injury or was based on reports of witnesses to the accident. Children under three years of age were also included if there was a witness to the accident. The size of the injury was measured based on the maximum diameter. RESULTS: Out of the total of 193 patients, patients with scalp bleeding totaled 126 (65.2%), and patients without scalp bleeding totaled 67 (34.8%). Among patients with scalp bleeding, patients with intracranial injuries numbered nine, and among patients without scalp bleeding, patients with intracranial injuries numbered 17 (P=0.001). Among patients who showed evidence of scalp swelling with no scalp bleeding, the relationship between the size of the scalp swelling and intracranial injury was statistically significant when the size of the scalp swelling was between 2 cm and 5 cm. CONCLUSION: Among patients who visit an emergency medical center due to traumatic head injury, patients with no scalp bleeding, but with scalp swelling between 2 cm and 5 cm, should undergone more accurate and careful examination, as well as as a brain CT.

A statistical analysis of 92 patients with ureteral stones, who had been treated by conservative treatment was undertaken to elucidate the correlation between size of calculi and the probability of spontaneous passage. The overall rate of spontaneous passage was 69.5%. Average stone size and treatment duration were 4.0, 5.0, 4.2mm and 9.4, 10, 6.3days in order of upper. mid, lower ureter. The rate of spontaneous passage according to stone size was 80% in less than 5mm. 15% in 5-6mm and 5% in 6-7mm. Therefore, when stones are smaller than 5mm in diameter, higher chances of spontaneous passage would be anticipated in 6-7days.

Fifteen cases of papillary cystic tumor of the pancreas (PCTP) were studied (14 female patients, one male patient; mean age: 23.5 years). Most tumors developed in the head of the pancreas as a well circumscribed large mass. The tumor had a mean diameter of 6.7 cm(range; 2 to 15 cm). Histopathologically abundant delicate papillary fragments, monomorphic tumor cells and degenerative changes of the solid area of the tumor were characteristic. All but two cases had completely circumscribed capsules. Two cases had duodenal invasion; one of all cases had cul de sac metastasis. Compared with 12 non-aggressive tumors, the aggressive cases had larger tumor size (more than 9 cm) with a thicker capsule (more than 2 mm). In studies to investigate the prognostic index using nucleolar organizing region (NOR), proliferating cell nuclear antigen (PCNA) and flow cytometry as well as nuclear grade and mitotic index, we could not find the useful parameter to detect the malignant potential of PCTP. In the flow cytometric analysis of cellular DNA contents, two invasive cases and the only one case of the male patient among the non-aggressive group were aneuploid. In conclusion, although it is hard to predict the prognosis by microscopic findings only, those with a thick capsule and aneuploidy tend to be related to malignant potential.
