Although little attention has been paid to the less common rheumatoid involvement of the thoracic and lumbar regions, some studies have shown that rheumatoid synovitis with erosive changes can develop in these diarthrodial joints. We report a patient with seropositive rheumatoid arthritis (RA) involving the thoracic and lumbar vertebra with a collapse of the T12 vertebra, who was treated with percutaneous vertebroplasty. In this case of a painful pathological fracture due to RA, percutaneous vertebroplasty was found to be helpful in eliminating the pain. The paper presents the histological evidence, the pathogenesis and treatment of the thoracolumbar lesions affected by RA with a review of the relevant literature.

OBJECTIVE: The frontal sinus is frequently a troublesome anatomical obstacle to gain access to the medial anterior cranial base. Surgical approaches to and through the frontal sinus using osteoplastic frontal sinusotomy provide significant advantages to the treatment of lesions of the medial anterior cranial base in addition to the frontal sinus itself. However, appropriate management is necessary to avoid postoperative complications such as cerebrospinal fluid leakage, infection, mucocele formation, and deformity of the forehead. METHODS: The advantages and shortcomings of the approach along with the surgical technique are reported based on our clinical experience with pertinent literature review. The approach using the osteoplastic frontal sinusotomy was applied to two cases of osteoma in the frontal sinus, seven cases of craniofacial tumors, a case of chordoma in the sphenoid and clivus, and two cases of intradural lesions in the anterior cranial fossa. The frontal sinus was managed in such a way as to prevent the postoperative complications. RESULTS: All patients underwent gross total resection of the tumors. With a mean follow-up of 26 months, there were no postoperative complications related to frontal sinus violation. CONCLUSION: The neurosurgical approaches via the frontal sinus using osteoplastic frontal sinusotomy are versatile for various lesions of the anterior cranial base in patients with large frontal sinuses. In situations that the frontal sinus have to be violated to approach medial anterior cranial base, the osteoplastic frontal sinusotomy provides such advantages as optimal frontal sinus control to prevent postoperative complications; increases viewing angle with superior trajectory from nasofrontal suture; lower incidence of pnemocephalus due to minimal dural exposure; and excellent cosmesis without frontal burr holes.

Eventhough surmountable amounts of genes are being cloned and a number of methods are being developed by human genome project, it's not easy to predict possible functions of genes and determine the chromosomal locations of genes. In this experiment, cDNA pool was made from 18 weeks old human fetal brain and analyzed the sequences. FB174 clone was chosen, in situ hybridization histochemistry was performed on developing and adult rat tissue section to observe the tissue specificity and developmental expression of this gene. To observe the chromosomal location of FB174 clone, the genomic DNA from human genomic library was isolated and fluorescence in situ hybridization was carried out. By sequencing and sequence search with GenBank data it was revealed that cloned FB174 cDNA was quite similar to translationally controlled tumor protein which is known to locate to human chromosome 13q14. The expression of FB174 mRNA was not detected in rat tissue sections by in situ hybridization histochemistry. Fluorescence in situ hybridization using biotin labeled FB174 probe resulted in specific labeling of human chromosome 7q22. These results and high sequence homology of FB174 to known translationally controlled tumor protein suggest that FB174 clone may be a new translationally controlled tumor protein-related gene.

PURPOSE: To report a case of multicentric Castleman disease that presented with scleritis. CASE SUMMARY: A 42-year-old male presented with decreased visual acuity in the left eye. Castleman disease had been diagnosed 21 months before and treated with systemic steroids and combined chemotherapy. Best-corrected visual acuity (BCVA) of the left eye was 0.02 and the intraocular pressure was 42 mmHg. Scleral edema and corneal edema were noted using a slit lamp examination. The anterior chamber cell was 2+ according to Standardization of Uveitis Nomenclature criteria. The fundus was invisible due to the anterior segment lesion. After one month, scleritis developed in the right eye and the patient complained of ocular pain. Topical steroids and non-steroidal anti-inflammatory drugs were prescribed. Due to recurrent scleritis and anterior uveitis, cataract extraction and laser iridectomy were performed on the left eye, and systemic steroids and the antimetabolite methotrexate were started. After 9 years of follow-up, all medications were stopped and there was no recurrence of inflammation, with a BCVA of 1.0 in both eyes. CONCLUSIONS: Treatment of a patient with scleritis accompanied with Castleman disease using systemic steroids and methotrexate resulted in a good prognosis.

Purpose: We report two cases of tacrolimus-related transplant-associated thrombotic microangiopathy (TA-TMA) retinopathy in leukemia patients who had undergone allogenic peripheral blood stem cell transplantation (PBSCT).Case summary: (Case 1) A 58-year-old woman with a history of PBSCT due to acute myelocytic leukemia and taking tacrolimus was referred to the ophthalmology clinic with visual disturbance. Her visual acuity (VA) was 0.4 in the right eye and 0.5 in the left eye. Multiple cotton wool spots and retinal hemorrhages were found in both eyes on fundus examination. Multiple capillary non-perfusions were seen on fluorescein angiography (FA). Tacrolimus-related TA-TMA retinopathy was suspected. Tacrolimus was discontinued and plasmapheresis was performed. After 3 months, neovascular glaucoma developed and her VA became “counting fingers” at 20 cm in both eyes. (Case 2) A 20-year-old man with a history of PBSCT due to acute lymphocytic leukemia and taking tacrolimus was referred to our clinic because of decreased VA in both eyes. His VA was 0.05 in the right eye and 0.025 in the left eye. Fundus and FA findings were the same as in Case 1, and the patient was suspected to have tacrolimus-related TA-TMA retinopathy. Tacrolimus was discontinued and plasmapheresis was performed. His VA was 0.2 in the right eye and 0.4 in the left eye at 1 month after treatment. Conclusions It is necessary to consider TA-TMA retinopathy in leukemia patients taking calcineurin inhibitors, such as tacrolimus, who have decreased VA. Early diagnosis and treatment are important.

BACKGROUND: During the period from April to June 1996, an outbreak of typhoid fever occurred in SuYoung-Ku, Pusan city. We performed the molecular epidemiological analysis and drug susceptibility test for 48 isolates of Salmonella typhi from the outbreak. METHODS: Chromosomal DNA of S. typhi was digested with the restriction endonuclease Spe I and the resulting restriction polymorphism was observed on pulsed field gel electrophoresis (PFGE). Phage typing was performed using Vi-phages, and antimicrobial susceptibility test was done by Disc diffusion method. RESULTS: On phage typing, 2 isolates were M1 phage type, 2 E1 phage type and 44 untypable. The PFGE analysis on 14 to 16 chromosomal DNA restriction fragments ranged from 50 Kb to 1000kb showed 2 different patterns of restriction fragments, divided into group A and B. Forty-seven isolates belonged to group A that were allocated into A1 (42 strains), A2 (1 strain), A3 (3 strains), A4 (1 strain), and one strain was grouped into group B. In the F-value of genetic similarity of the epidemic S. typhi strains, there was low similarity (F value:0.2-0.258) between group A strains and group B strains. However, the subgroup strains (A1-A4) showed high similarity (F value:0.8-0.897) each other. The drug susceptibility test showed susceptibility to ampicillin, carbenicillin, cephalothin, chloramphenicol, tobramycin, gentamicin, kanamycin, nalidixic acid, neomycin, polymyxin B, streptomycin, tetracycline, trimethoprim-sulfamethoxazole, ciprofloxacin and norfloxacin. CONCLUSION: This study showed that phage typing and PFGE were very useful as a tool to investigate molecular analyses of epidemic S. typhi strains this study.

BACKGROUND: Identification of the genes expressed differentially in renal cell carcinoma (RCC)but not in the non-cancerous kidney is important for understanding the molecular basis ofrenal cell carcinoma and for defining possible prognostic value and therapeutic intervention.We investigated the changes in gene expression accompanying the development and progression of kidney cancer by cDNA microarrays. METHODS: To identify molecular alterations in renal cell carcinoma, we measured expression profiles for paired neoplastic and noncancerouskidney samples from an individual by means of a cDNA microarry representing 7, 500genes. Of the differentially expressed genes, we assessed the decorin gene at the proteinlevel using immunohistochemistry. RESULTS: The 60 genes were noted to have more than a fivefold change in expression (either increased or decreased) in RCC compared to the noncancerouskidney. The changed genes are those associated with signal transduction, metabolizingenzymes, the cytoskeleton, cell adhesion, cell cycle control, modulation of transcription, the tumor suppressor gene and tumor antigens. Under immunohistochemistry, the expressionof decorin was significantly decreased in the tumor than in the non-cancerous kidney.The expression rate of decorin was not associated with the patient's sex, age, histologic type, Fuhrmann nuclear grade and T stage. CONCLUSION: The author predicted that these geneexpression profiling experiments will lead to improvements in the basic understanding of renaltumor pathogenesis and will promote the discovery of novel molecular markers for renal tumordiagnosis and therapy.
