BACKGROUND: Ketorolac is a potent anlagesic drug which has anti-inflammatory action and this drug may decrease the needed amount of opioids when used together with them for postoperative pain control. Preemptive analgesia with these drugs is still controversial. The analgesic effect and the presence of preemptive analgesia of a nalbuphine-ketorolac combination were examined in upper abdominal surgical patients. METHODS: Thirty patients undergoing elective upper abdominal surgery were randomly allocated into two groups. Each group received 10 mg of nalbuphine as a bolus dose just before starting IV-PCA which contained nalbuphine 70 mg and ketorolac 150 mg in 88 ml of 5% dextrose water. Group I (n=15) received drugs before starting the operation and group II received them at the end of the operation. The basal rate, PCA dose and lock-out interval were 1.5 ml, 1.5 ml and 10 minutes, respectively. In each group, the postoperative visual analogue scale (VAS) score, degree of satisfaction, total amount of drug used and side effects were checked and compared with corresponding figures in the other group for two postoperative days. RESULTS: Postoperative pain after upper abdominal surgery was controlled well in all patients and there were no significant differences in VAS scores between the two groups. Most patients were satisfied with this regimen. There were no remarkable side effects. Preemptive analgesia of nalbuphine-ketorolac combination was not found. CONCLUSIONS: IV-PCA administration of nalbuphine 70 mg and ketorolac 150 mg combination is an effective method to control postoperative pain in upper abdominal surgical patients. Preemptive analgesia is not found with this regimen.

Bacille Calmette-Guerin (BCG) lymphadenitis is the most common complication of BCG vaccination. It commonly occurs in infants aged <6 months involving ipsilateral axillary lymph nodes. We described BCG lymphadenitis in a 22-month-old boy presenting swelling of left supraclavicular lymph node that was confirmed by real-time polymerase chain reaction (PCR) and the multiplex PCR targeting the region of difference (RD).

Fine needle aspiration cytology of the salivary lesions was performed on 221 patients at Soonchunhyang University Hospital for 10 years. Of 221 aspirates, 6 aspirates(2.7%) were inadequate, 116 cases(52.5%) were non-neoplastic lesions, 76(34.4%) cases were benign neoplasms and 23 cases(10.4%) were malignant neoplasms. The cytologic diagnoses could be correlated with histologic findings in 58 cases. FNAC correctly discriminated between neoplastic and nonneoplastic lesions in fifty-seven lesions and failed in a case, and overall accuracy, sensitivity, and specificity were 98.3%, 98.0%, and 100.0%. FNAC correctly discriminated malignant neoplasms from benign neoplastic/non- neoplastic lesions in fifty-three cases and failed in five cases, and overall accuracy, sensitivity, and specificity were 91.3%, 72.7%, and 95.7%. Among three false negative cases, two mucoepidermoid carcinomas were misdiagnosed as mucocele and benign neoplasm, and an acinic cell carcinoma were misdiagnosed as Warthin's tumor. Two false positive cases were a Warthin's tumor misdiagnosed as squamous cell carcinoma and a pleomorphic adenoma misinterpretated as suggestive of malignancy. In conclusion, diagnostic accuracy of FNAC of salivary lesions is high, and the possibilities of low grade mucoepidermoid carcinoma and acinic cell carcinoma should be considered on hypocellular smears with mucoid or fluidy background.

BACKGROUND: Melanocytes grown in pure monolayer culure lack many of the cellular interactions that exist in vivo. This can be partially overcome by growing melanocytes together with other epidermal cells in skin equivalent models. OBJECTIVE: The objective of the present study was to grow human melanocytes in human epidermis reconstructed on dermal substrates in vitro and to examine their response to UV radiation. METHODS: The skin equivalents were prepared by seeding cultured human keratinocytes together with cultured human melanocytes(in a ratio of 5%) onto de-epidermized dermis. After 7 days of culture, they were exposed to UVB irradiation(total 150m J/cm over 5days). On day 12 of air exposure the sections of the skin equivalents were prepared for histology. The structure of the skin equivalents was studied following staining with hematoxylin and eosin. Melanocytes were characterized by DOPA staining and by immunohistochemistry. RESULTS: Melanocytes were localized singly within the basal layer of the reconstructs. Melanin was also visible both in the melanocytes and in neighboring keratinocytes. There was an increase in melanocyte size and dendricity following UV irradiation. Melanocytes became positive to staining with HMB-45 antibody following UV irradiation. CONCLUSION: Our results indicate that melanocytes grown in reconstructed human epidermis are functional and capable of responding to UV irradiation.

BACKGROUND: Recently, the molecular pathologic investigation for clonality in lymphomas has been introduced and has gained a role in the diagnosis of lymphomas. In fact, the clonality test using TCRGR phenomenon has been done by Southern blot analysis (SBA) and polymerase chain reaction (PCR) for molecular pathologic diagnosis of T cell lymphomas. However, it is difficult to perform SBA with paraffin embedded specimens or with samples of small skin biopsies. OBJECTIVE: We investigated the efficacy of PCR amplification of TCR gene in paraffin em-bedded cutaneous T cell lymphomas. METHODS: Iii this study, the clonality was assessed by polymerase chain reaction (PCR) analysis of T cell receptor gamma (TCR) gene from the DNA extracts obtained from paraffin em-bedded tissues (PET) of malignant T cells, B cell lymphomas, and benign cutaneous T cell proliferative disorders. Heteroduple-x-analyses were also performed to rule out the false positives. RESULTS: Among the total of 62 cases analyzed, monoclonality was observed in 4 out of 10 mycosis fungoides, 7 out of 9 cutaneous T cell lymphomas excluding mycosis fungoides, 1 out of 3 angiocentric lymphomas, 2 out of 2 lymphomatosis papulosis, 1 out of 7 large plaque parapsoriasis, and 1 out of 2 T cell lymphomas in other organs. No monoclonality was observed in 9 inflammatory cutaneous diseases, 5 small plaque parapsoriasis, 4 cutaneous B cell lymphomas, and 11 B cell lymphomas in lymph nodes. CONCLUSION: The results suggest that the PCR method and heteroduplex analysis used in this study were not only practical but also efficacious for the diagnosis of cutaneous T cell lymphomas using tissues embedded in paraffins.

PURPOSE: We performed this study to evaluate the alterations in renal function for patients with ileal conduit and ileal orthotopic neobladder MATERIALS AND METHODS: From January 1999 to June 2004, 48 patients who had undergone radical cystectomy with urinary diversion were included in our study. The patients were divided into two groups according to the types of urinary diversion. One group consisted of 29 patients with ileal conduit and the other group consisted of 19 patients with ileal W neobladder. The mean age of the ileal conduit group and the ileal W neobladder group were 65.6+/-9.9 years and 60.8+/-8.3 years, respectively. The preoperative and postoperative blood urea nitrogen/creatinine (BUN/Cr) levels, postoperative complications and postoperative GFR, as measured by (99m)Tc-DTPA scans, were compared between the two groups. RESULTS: For the postoperative complications, stricture at the ureterovesical anastomosis site occurred in 1.7% (1/58 renal units) of the ileal conduit group and in 10.5% (4/38 renal units) of the ileal W neobladder group. Acute pyelonephritis occurred in 5.2% (3/58 renal units) of the ileal conduit group and in 5.3% (2/38 renal units) of the ileal W neobladder group. The pre- and postoperative serum BUN/Cr levels were 20.8/1.3 and 24.8/1.6, respectively, in the ileal conduit group, and 17.2/1.1 and 18.8/1.2, respectively, in the ileal W neobladder group. There were no statistical significant differences between the pre- and postoperative changes of the serum BUN/Cr levels for both groups. The GFR, as measured by (99m)Tc-DTPA scans, were 77.6 and 78.7ml/ min/1.73m2 in the ileal conduit group and the ileal W neobladder group, respectively. There were no statistical significant differences between the two groups. CONCLUSIONS: There were no significant differences in renal function between the ileal conduit and ileal W neobladder.

Marden-Walder syndrome is characterized by a mask-like face, blepharophimosis, joint contractures, and psychometer retardation. We report a newborn infant with the clinical features of the syndrome. He was diagnosed with clinical findings of mask-like face, blepharophimosis, micrognathia, camptodactyly, arachnodactyly, multiple contractures, and hypotonia. The infant died of aspiration pneumonia at 5 months. A brief review of related literature is also presented.

BACKGROUND: The pathogenesis of psoriasis may involve the interleukin (IL)-23 and Th17-mediated immune responses. Th17 cells secret IL-17 and IL-22, which mediates dermal inflammation and acanthosis. OBJECTIVE: As inhibitor of nuclear factor kappaB kinase-alpha (IKKalpha) has been previously identified as a primary regulator of keratinocyte differentiation and proliferation, we proposed that IL-17 and IL-22 might affect keratinocyte differentiation by changing the expression of IKKalpha. METHODS: We employed HaCaT cells maintained culture medium at a low calcium concentration (0.06 mM) and induced differentiation by switching to the high concentration (2.8 mM) media with IL-17 or IL-22, then compared the IKKalpha expression and the cell cycle. We employed reconstituted human epidermal skin (Neoderm) and mice ears for the in vivo studies. RESULTS: Elevated calcium concentration induced IKKalpha expression and terminal differentiation with cell cycle arrest in HaCaT cell cultures. Moreover, IL-17 and IL-22 treatment also induced IKKalpha in HaCaT cells and reconstituted human epidermis. IKKalpha induction was also noted, following the injection of IL-17 and IL-22 into mice ears. CONCLUSION: Although the induction of IKKalpha was accompanied by keratinocyte differentiation, IL-17 and IL-22 did not affect calcium-mediated differentiation or the cell cycle. Rather, IL-17 and IL-22 appear to contribute to the inflammation occurring via the induction of IKKalpha from keratinocytes or skin layers.

BACKGROUND: Bacterial contamination of platelets represents the highest infectious risk for a transfusion. In this study, we evaluated 2 culture-based systems that have been approved by the US FDA for bacterial screening. METHODS: Platelet concentrates were inoculated with 5 bacterial species to give a final concentration of 10(0), 10(1) and 10(2) CFU/mL. Samples for culture were taken immediately after inoculation (0 hr sample) and after 24 hrs (24 hr sample). For the BacT/ALERT 3D system, a 10 mL sample was inoculated into an aerobic culture bottle and incubated for 7 days. For the Pall eBDS system, 3 mL samples were taken from the 0 hr and 24 hr samples, respectively. The samples were incubated for 24 hrs and 30 hrs. RESULTS: Both systems detected all inoculated units both in the 0 hr and 24 hr samples, except for units inoculated with K. pneumoniae. Eleven units out of 30 units inoculated with K. pneumoniae were detected by the BacT/ALERT 3D system in the 24 hr samples. The Pall eBDS system detected 8 of 30 units in the 24 hr samples. CONCLUSION: Implementation of either system will decrease the risk of transfusing bacterially contaminated platelets. However, testing for bacterial contamination will not completely prevent septic transfusion reactions; pathogen inactivation that is now available should also be considered as an alternative method to reduce the risk of bacterial contamination.
