We reviewed 37 skin biopsies obtained from 35 patients with secondary syphilis during the period of 9 years from January 1980 to June 1988, which had been diagnosed by dark field examination, serologic tests for syphilis, and identification of spirochetes by immunoperoxidase method (avidin-biotin complex) in the skin biopsies. We investigated the histologic features of the skin lesions in secondary syphilis according to the types and patterns of inflammatory cell infiltration in the dermis, vascular reactions and epidermal changes. We matched these histologic findings with the clinical features of the skin lesions. The results were as follows; 1) The histologic patterns of dermal infiltrate in order of frequency were as follows; junctional pattern in 14 biopsies (38%), lichenoid pattern in 10 biopsies (27%), diffuse pattern in 5 biopsies (14%), patchy pattern in 3 biopsies (8%), normal pattern in 3 biopsies (8%) and undertermined in 2 biopsies (5%). 2) The dermal infiltration of plasma cells was found in 24 biopsies (65%). All the biopsies of diffues and lichenoid patterns, 7 biopsies of junctional and one biopsy of patchy pattern showed plasma cells but none in normal pattern. 3) Eosinophils were observed in the dermis in 11 biopsies (30%). There was no difference in incidence of eosinophils in the dermis among morphologic patterns. However, they were frequently seen in the dermis and epidermis of condyloma lata (4 of 7 biopsies). 4) The vascular changes in the dermis included endothelial cell swelling in 23 biopsies (62%), endothelial cell proliferation in 22 biopsies (60%) and vascular dilatation in 10 biopsies (27%). They were most commonly observed in the lichenoid pattern followed by diffuse and junctional patterns. Three cases showed lymphocytic vasculitis. 5) Epidermal changes were seen in all of the biopsies exocytosis, parakeratosis, hydropic change of basal cells, acanthosis, spongiosis, keratinocyte necrosis and hyperkeratosis in the order of frequency. 6) In relation to the clinical manifestations, junctional pattern (14 biopsies) consisted of 6 papulosquamous lesions, 5 macules and 3 papules. Lichenoid pattern (10 biopsies) consisted of 7 papulosquamous lesions and 3 papules. All the biopsies showing diffuse pattern (5 biopsies) appeared in condyloma lata. Patchy pattern (3 biopsies) consisted of 2 macules and 1 papule. All of the normal pattern (3 biopsies) appeared in macules. In conclusion, with dermal and epidermal changes, the acknowlegement of the 5 basic histologic patterns in secondary syphilis seems to be very helpful for the diagnosis of syphilis.

We reviewed 48 skin bicpsies obtained from 48 patients with epidermal nevus during a 10 year period from January 1981 to December 1990. The results are summarized as follows : 1) Of our 48 patients, 23 were male and 25 were female, and male to female ratio was 1 to 1.1. 2) The average of the patients was 19.8 years at the time of diagnois. 3) Lesions were present at birth in 45.7 percent of patients, and most of the remainder de veloped in childhood. The mean age of onset was 7.7 years. 4) The clinical varieties of the nevi in 48 patients were classified according to caicegories of nevus verrucosus, including systematized epidermal nevus, nevu, unius lateris, ichthyosis hystrix, epidermal nevus syndrome and inflammatory linear veirucous epidermal nevus. The most common type was nevus verrucosus(88.6%). 5) A large variety of histopathologic changes can be seen in epidermal nevi. The most common histopathologic .ype was nonspecific(31.3%), follows by common(12.5%), epidermolytic hyperkertosis(12.5%), and acanthosis nigricans(10.4%). 6) The most commonly affected area was head and neck(48.5%) followed by trunk(28.6%), upper limb(11.4%) and lower limb(2.9%).

The 5'- and 3'-side half of liver type glucose transporter (GLUT2) cDNA was amplified from total RNA or mRNA by reverse transcriptase-polymerase chain reaction (RT-PCR). The amplified 5'-side fragment of GLUT2 cDNA was inserted into pGEM4Z and named pGLGT1, and the 3'-side fragment of GLUT2 cDNA was inserted into the HindIII site of pGLGT1 to construct pGLGT2 which contains an entire open reading frame of GLUT2 cDNA. The GLUT2 cDNA in pGLGT2 was transferred to an eukaryotic expression vector (pMAM) to construct pMLGT, which was expressed in the insulin-sensitive Chinese hamster ovary (CHO) cells. Western blot analysis showed that the GLUT2 gene in pMLGT was expressed in the transfected CHO cells successfully. The GLUT2 content in the plasma membrane fraction of insulin-treated CHO cells expressing GLUT2 increased 3.8-fold compared to that of the control group. This result suggests that GLUT2, which is not subjected to translocation by insulin in the cells of its major distribution, can be translocated if it is expressed in the suitable cells sensitive to insulin action.

Pain is one of the most complex human experience and the commonest cause of stress and the most frequent symptom that makes people seek medical help. The mechanism of its production and perception are poor understood. Since the past, various procedures have been tried to control or relieve pain. It had been observed that acupuncture stimulation has been effective in the relief of painful conditions. However, up to the present there had been no definite proof that acupuncture treatment has cured any pathological condition. Work is at present proceeding to make this a practical possibility. Recently, in modern medical science, several experiments are in progress and in some cases, cure had been obtained but until these studies are completed and proved to be effective, it is impossible at the present stage to evaluate whether these occasional cures are statistically significant. So, we launched studies and observations at our pain clinic at St. Paul's Hospital employing the "Somatosensory evoked Potential",(SEP) responses for chronic pain patient to relieve pain with acupuncture. The median and sural nerve of patients with chronic pain were stimulated and recorded using the SEP. Recordings were made before and after the acupuncture therapy was initiated. We analyzed the recorded SEP responses to see if ther are any physiological effects of the acupuncture therapy in patients with chronic pain. Findings: The important changes of the SEP responses recorded during acupuncture therapy in patients with chronic pain were the suppression of the amplitude of the SEP waves and delayed latency of the responses, similar to those manifested by patients, who are under morphine therapy. Then, naloxone an antagonist to morphine was administered. The effects were the same, that is the SEP responses were reversed in both the patients under morphine therapy and those under acupuncture therapy. So, we postulated that, since the meridian system is closely connected to the posterior column of the spinal cord conducting system, which is concerned in the somatosensory conducting system, peripheral stimulation by acupuncture may bring about the so called "pain suppression of descending system", which is closely connected to the meridian system of acupuncture. Though it is quite early to draw positive and definite conclusions, the results are very encouraging. More cases and further observations are advocated.

There are many conditions which are associated with neutropenia, such as infections, chemical and physical agents, and hematopoietic diseases. But ticlopidine-induced neutropenis is rarely reported in Korea. We experienced a case of neutropenia which developed after approximately 1 month of ticlopidine administrarion to a stable angina pectories patient. A 59 year-old woman with stable angina pectoris was placed on ticlopidine. Forty days later, she was admitted for high fevers and shaking chills. On admission, leukocyte count was 900/mm (3) (neutrophil 0/mm (3)), hemoglobin was 11.8g/dl, and platelet count was 440.000/mm (3). After confirming ticlopidine-induced neutropenia by bone marrow aspiration and biopsy, we administated rhG-CSF (neutrogen (r), Choongwae. Co. Korea) at a dose of 3-5ug/kg daily. On the 25th day of treatment, leukocyte count reached 2,890/mm (3). She experienced no adverse effects of rhG-CSF treatment and recorved completely. We assume that the rapid recovery of granulocytes was attributable to rhG-CSF, and we suggest that rhG-CSF should be tried in a patients with ticlopidine-induced neutropenia with depletion of myeloid precursors in the hypocelluar bone marrow.

Ankylosing spondylitis (AS) is a chronic inflammatory disease predominantly affecting the axial skeleton. AS treatment aims to reduce pain and inflammation and maintain functional capacity. Nonsteroidal anti-inflammatory drugs are the first-line treatment for those with active AS. While for peripheral arthritis, sulfasalazine or local glucocorticoid injection can be used, these are not recommended for axial symptoms. Twenty years ago, biological products that target the tumor necrosis factor (TNF) were developed. These have been approved for use in rheumatoid arthritis and AS. Since the introduction of these TNF inhibitors, the control of disease activity in AS has improved markedly. TNF inhibitors, including both anti-TNF-alpha monoclonal antibodies and recombinant TNF soluble receptors, can be considered for patients with persistently active disease despite nonsteroidal anti-inflammatory drug treatment. Recently, interleukin-17 inhibitors have also been approved for use in AS patients with insufficient responses to TNF inhibitors. Ongoing clinical trials are exploring the effect of Janus kinase inhibitors against AS. This review summarizes the current pharmaceutical treatment for AS, focusing on the biological products. Recommendations for AS management are also discussed in this review.

PURPOSE: Thallim-201 (201Tl) brain SPECT, which can represent cellular activity of brain lesions, may provide more useful information in differentiating between benign and malignant brain lesions more so than CT or MRI, that merely represents anatomic changes or breakdown of blood brain barrier. We used 201Tl brain SPECT prospectively to evaluate the utility of 201Tl-indices as an indicator of benign or malignant lesions. MATERIALS AND METHODS: We studied 28 patients. There were 13 cases of benign lesions (3: nonspecific benign lesion, 3: meningioma, 2: low grade glioma, 1: tuberculoma, central neurocytoma, hemangioblastoma, radiation necrosis, and choroid plexus papilloma) and 15 cases of malignant lesions (6: glioblastoma multiforme, 5: anaplastic glioma, 2: medulloblastoma, 1: metastasis and lymphoma). In all patients, CT and/or MRI were obtained and then 201Tl brain SPECT was obtained with measuring mean 201Tl index and peak 201Tl index. An unpaired t-test was performed to compare the 201Tl-indices and pathologic diagnoses to evaluate the utility of 201Tl-indices as an indicator of benign or malignant lesions. RESULTS: There were no statistically significant difference in 201Tl-indices between benign and malignant brain lesions (P>0.05). CONCLUSION: These results demonstrated that we could not use 201Tl indices on brain SPECT alone as an indicator of benign or malignant brain lesions.

STUDY DESIGN: A retrospective study. PURPOSE: To analyze the treatment outcome of patients with lower thoracic and lumbar fractures combined with neurological deficits. OVERVIEW OF LITERATURE: Although various methods of the surgical treatment for lower thoracic and lumbar fractures are used, there has been no surgical treatment established as a superior option than others. METHODS: Between March 2001 and August 2009, this study enrolled 13 patients with lower thoracic and lumbar fractures who underwent spinal canal decompression by removing posteriorly displaced bony fragments via the posterior approach and who followed up for more than a year. We analyzed the difference between the preoperative and postoperative extents of canal encroachment, degrees of neurologic deficits and changes in the local kyphotic angle. RESULTS: The average age of the patients was 37 years. There were 10 patients with unstable burst factures and 3 patients with translational injuries. Canal encroachment improved from preoperative average of 84% to 9% postoperatively. Local kyphosis also improved from 20.5degrees to 1.5degrees. In 92% (12/13) of the patients, neurologic deficit improved more than Frankel grade 1 and an average improvement of 1.7 grade was observed. Deterioration of neurologic symptoms was not observed. Although some loss of reduction of kyphotic deformity was observed at the final follow-up, serious complications were not observed. CONCLUSIONS: When posteriorly displaced bony fragments were removed by the posterior approach, neurological recovery could be facilitated by adequate decompression without serious complications. The posterior direct decompression could be used as one of treatments for lower thoracic and lumbar fractures combined with neurologic injuries.

Between March 1994 and March 1995, 10 patients with thoracolumbar burst fractures underwent a one-stage operation consisting of anterior decompression, reduction, bony fusion with iliac bone and stabilization with Kaneda device. The mean follow-up was 6.4 Months. Most patients with incomplete neurologic lesions showed postoperative improvement and were upgraded one or two steps in the Frankel scale. No patient showed neurological deterioration after surgery. Loss of reduction was 5.5 degree during follow-up period. Anterior decompression and strut fusion was used to effectively recover the neurological deficit and reduce the pain in a thoraco-lumbar burst fracture.

BACKGROUND AND OBJECTIVES: Primary percutaneous coronary intervention (PCI) has been reported to be effective reperfusion therapy for acute myocardial infarction (AMI). In the very thrombotic environment of AMI, primary PCI, with heparin-coated stents, has been known to reduce the early reocclusion of the stented vessel by preventing thrombosis. However, little data exist regarding the long-term clinical outcomes. The aim of our study was to evaluate the safety, feasibility and long-term efficacy of heparin-coated stents in AMI. SUBJECTS AND METHODS: Between January 1998 and July 2002, primary PCI with heparin-coated stents was performed in 132 consecutive patients (98 males, with a mean age of 56.3+/-0.7 years) admitted with the diagnosis of AMI within 12 hours from the onset of the chest pain. Major adverse cardiac events (MACE), including death, MI, TLR (target lesion revascularization) and CABG, were recorded during hospitalization and the follow-up period. Angiograms were obtained at the baseline, after stent implantation and at 6 months following implantation. RESULTS: The angiographic and procedure success rate was 96.2%. During hospitalization, there was no evidence of reocclusion of stented vessel, but 1 patient underwent a repeat PCI due to dissection. There were no bleeding complications. A six-month angiographic follow-up was completed in 47.2% of eligible patients and binary restenosis was present in 20.1%. During the long-term clinical follow-up (mean follow-up period 37.2+/-7.2 months), there were 12 deaths, 1 myocardial infarction and 18 TLR. The MACE free survival rate was 76.5%. CONCLUSION: Primary PCI, with heparin-coated stents, shows favorable long-term clinical outcomes.
