Résumé

Background@#Our study evaluated the prevalence and pattern of T-score discordance between the spine and hip in Korean patients with atypical femoral fracture (AFF) and femur neck fracture (FNF). @*Methods@#A total of 49 patients (all women) who were treated for AFF and 1:3 matched 147 female patients with FNF were included from January 2012 to August 2022. A discordance of more than 1.5 between lumbar spine and femur neck bone mineral density (BMD) was defined as a difference and divided into 3 groups: lumbar low (LL; lumbar BMD is less than femur neck BMD), no discordance (ND), and femur neck low (FL; femur neck BMD is less than lumbar BMD). We compared the prevalence and pattern of discordance between 2 groups, and the associated risk factors of T-score discordance among the subjects were evaluated using regression analysis. @*Results@#The prevalence of discordance was significantly higher in patients with AFF (51%) than in those with FNF (25.2%; p<0.001). LL discordance was found in 46.9% of the patients with AFF but only 4.8% in those with FNF. Conversely, FL discordance was found in 4.1% of the patients with AFF and 20.4% in those with FNF, respectively. No specific risk factor was found as T-score discordance in the 2 groups. @*Conclusions@#Clinicians should be aware that the pattern of T-score discordance can vary depending on the location of osteoporotic fractures. In addition, a longitudinal study would be necessary to verify the pattern of T-score discordance related to the osteoporotic fracture location.

Résumé

A subepithelial tumor-like esophageal carcinoma is rare. We report a case of an esophageal squamous cell carcinoma with lymph node metastasis presenting as a small subepithelial tumor. A 68-year-old man presented to our hospital complaining of hoarseness since last three months. Endoscopic examination revealed a 1 cm hard and fixed subepithelial tumor with surface erosion in the lower esophagus. A biopsy specimen was obtained using conventional forceps, and histopathological evaluation revealed few atypical squamous epithelial cells. Subsequent EUS demonstrated a homogeneous hypoechoic lesion in the deep mucosal layer. A CT scan of the chest showed a 3 cm mass in the right upper paratracheal area. EUS-guided fine needle biopsy of the lesion led to the diagnosis of squamous cell carcinoma with lymph node metastasis.

Résumé

Arthritis damages the cartilage within joints, resulting in degenerative changes, including loss of function and joint instability. Ankylosing spondylitis (AS) is a chronic inflammatory condition affecting the spine and bone-to-tendon attachment area within the sacroiliac joint leading to back pain and progressive spinal stiffness. In the final stages, AS causes hyperkyphosis-a condition closely tied to the human leukocyte antigen-B27 gene. Rheumatoid arthritis is a chronic, systemic autoimmune disease characterized by the simultaneous inflammation of the synovium of multiple joints, leading to joint damage (e.g., destruction, deformation and disability). In the past, nonsteroidal anti-inflammatory drugs or conventional disease-modifying antirheumatic drug (DMARDs) have been used for the treatment of these autoimmune diseases, but biologic DMARDs have recently been introduced with excellent results. Gout is a chronic inflammatory disease that causes an alteration of joints resulting in severe pain. Specifically, gout is associated with an accumulation of uric acid within the body resulting from dysregulated purine metabolism, causing recurrent paroxysmal inflammation in the joints. Allopurinol and febuxostat are the primary treatment options for individuals with gout. It is necessary to have an accurate understanding of the pathogenesis, pathological ecology and treatment of AS, rheumatoid arthritis, and gouty arthritis, which are the representative diseases that may cause inflammatory arthritis.

Résumé

The volume of hip arthroplasty is stiffly increasing because of excellent clinical outcomes, however it has not been shown to decrease the incidence of transfusions due to bleeding related to this surgery. This is an important consideration since there are concerns about the side effects and social costs of transfusions. First, anemia should be assessed at least 30 days before elective hip arthroplasty, and if the subject is diagnosed as having anemia, an additional examination of the cause of the anemia should be carried and steps taken to address the anemia. Available iron treatments for anemia take 7 to 10 days to facilitate erythropoiesis, and preoperative iron supplementation, either oral or intravenous, is recommended. When using oral supplements for iron storage, administer elemental iron 100 mg daily for 2 to 6 weeks before surgery, and calculate the dose using intravenous supplement. Tranexamic acid (TXA) is a synthetic derivative of the lysine component, which reduces blood loss by inhibiting fibrinolysis and clot degradation. TXA is known to be an effective agent for reducing postoperative bleeding and reducing the need for transfusions in primary and revision total hip arthroplasties. Patient blood management has improved the clinical outcome after hip arthroplasty through the introduction and research of various agents, thereby reducing the need for allogeneic blood transfusions and reducing the risk of transfusion-related infections and the duration of hospitalizations.

Résumé

Primary rectal lymphoma is a rare disease among the gastrointestinal (GI) lymphoma. In particular, diffuse large B-cell lymphoma (DLBCL) transformed from mucosa-associated lymphoid tissue (MALT) lymphoma is often the primary type of GI lymphoma, mostly in stomach or duodenum, but has never been reported in rectum. Here we report an unusual case in which a 75-year-old male patient diagnosed with DLBCL transformed from MALT lymphoma in the rectum. The patient was diagnosed as rectal DLBCL transformed from MALT lymphoma as Lugano stage II2 and was treated with chemotherapy (R-CHOP) with CD-20 monoclonal antibody (rituxaimb). Complete remission of multiple lymphadenopathy and mass forming ulcer of the rectum was achieved after 6 cycles of R-CHOP. He has been free from disease for 12 months.

Résumé

Pulmonary tumor thrombotic microangiopathy (PTTM) is an uncommon and fatal malignancy-related pulmonary complication characterized by fibrocellular intimal proliferation of small pulmonary arteries and arterioles. It causes marked pulmonary hypertension, right-side heart failure, and sudden death. Diagnosis of PTTM is extremely difficult while the patient is alive. Here, we report a 44-year-old woman who presented with complaining of progressing dyspnea and pulmonary hypertension but with no history of cancer. She was diagnosed with PTTM caused by advanced gastric cancer ante mortem and was treated effectively with chemotherapy.

Résumé

BACKGROUND/AIMS: Inflammatory pseudotumor (IPT) of the liver is a rare disease characterized by chronic infiltration of inflammatory cells. However, the clinical characteristics and outcomes of IPT remain uncertain. METHODS: Clinical features, image findings, and outcomes of 55 patients with histologically proven IPT were evaluated. RESULTS: They consisted of 26 men and 19 women with median age of 65 years. Serum carcinoembryonal antigen and carbohydrate antigen 19-9 levels were normal in 42 patients (93.3%). Enhanced CT scans indicated poorly defined peripheral enhancement (82.5%) at the arterial phase and poorly defined hyperattenuating lesions with internal hypoattenuating areas at the equilibrium phase (77.0%). Gadolinium-enhancement MRI revealed poorly defined peripheral rim-like enhancement (77.8%). Ten patients underwent surgical resection and 35 were treated conservatively with or without antibiotics. No recurrence was noted after surgical resection during follow-up (1 to 48 months). In all patients who received conservative treatment, complete resolution or size reduction was noted during follow-up (1 to 192 months). CONCLUSIONS: CT and MRI provide clues to the diagnosis of IPT in patients with liver masses and normal tumor markers. However, due to the lack of pathognomonic findings, the clinician's suspicion and histological diagnosis are necessary to make an accurate diagnosis of IPT.

Résumé

A 28-year-old male was admitted to our medical center with general myalgia and fever. After a series of tests, he was diagnosed with P. vivax malaria. On the 5th hospital day, the patient complained of tingling sensation on both hands and feet, which acutely progressed to ascending symmetric motor paralysis. Nerve conduction velocity test and cerebrospinal fluid analysis showed albumino-cytologic dissociation, suggesting polyradiculopathy, and thus he was diagnosed with Guillain-Barre syndrome. After 5-day treatment with intravenous immunoglobulin, and antificial ventilator therapy the patient fully recovered. In the literature, only 22 cases of Guillain-Barre syndrome associated with Plasmodium have been reported; 19 cases were caused by Plasmodium falciparum and 3 were by P. vivax. Herein, we report the first case of Guillain-Barre Syndrome associated with P. vivax malaria in Korea.

Résumé

Bezoars are persistent concretions of indigestible materials found in the stomach. They can cause mucosal ulceration or wall perforation, gastritis, gastric outlet obstruction, or gastrointestinal bleeding. With the significant development of endoscopic techniques, many authors have reported the removal of bezoars using methods such as endoscopic mechanical lithotomy and chemical dissolution however, the outcomes differ according to the treatment method. We report a case treated successfully with an endoscopic Coca-cola injection and an argon plasma beam for 90 minutes. A 61-year-old man was admitted with a 4-day history of upper abdominal pain. A bezoar was detected by upper gastrointestinal endoscopy. The bezoar (10x8x6 cm) was dark brown in color and extremely hard. Attemptat endoscopic removal using a polypectomy snare failed. We then injected Coca-cola directly into the bezoar mass and sprayed it with an Argon plasma beam. Ninety minutes later, the bezoar was broken into pieces and removed. The bezoar was absent at the follow up endoscopy 2 weeks later.

Résumé

A low iodine diet (LID) is the recommended preparation for radioactive iodine treatment. However, the recommended duration and stringency of LID are different among each recommendation. More stringent LID is expected in Korea because Korea is a iodine-rich region. We investigated the decrement of urine iodine excretion by two-week stringent LID for remnant thyroid ablation with radioactive iodine in Korean patients with thyroid cancer, prospectively. MATERIAL AND METHOD: From November 2006, patients who referred to our hospital for remnant ablation after total thyroidectomy were included in this study. To decrease total body iodine, our protocol included three strategies. First, we checked medication which could inhibit the radioactive iodine uptake. Second, the date of I-131 treatment was scheduled at least 3 months later if contrast agent had been used. The last strategy was two-week stringent LID education by specialized nutritionist. Before and after two-week stringent LID, 24hr-urine iodine was analyzed respectively. 24hr-urine creatinine was also analyzed for determining more valid 24hr urine sampling subgroup. RESULTS: Total 51 patients were finally enrolled. Average of 24hr-urine iodine excretion was significantly lowered (787+/-2242 -> 85+/-85 microgram/d, p=0.03) after LID and 74.4% of patients reached below the recommended urine iodine excretion level ( 99+/-116 microgram/d, p=0.05) and 78.6% of patients met the criteria. CONCLUSION: Most patients could reach below the recommended urine iodine level after two-week stringent LID. Therefore, in our opinion, at least two-week stringent LID should be recommended in Korea.

Résumé

PURPOSE: To evaluate the clinical results of acquired claw toe deformities that had been treated with proximal lengthening of the long toe flexor tendons. MATERIALS AND METHODS: Seventeen patients with a claw toe deformity due to contracture of the long flexor tendons were treated with proximal lengthening of the long toe flexor tendons from January 1993 to January 2003 and were followed up for at least 1 year. The average age at the time of the operation was 42 years and the average follow-up period was 34 months. Achilles tendon lengthening was also performed in 14 cases with an equinus deformity. At the final follow-up, a residual toe deformity, toe pain during walking, patient's satisfaction, and limitation of the shoe-wear were assessed. RESULTS: At the final follow up, all cases showed a complete correction of a claw toe deformity, and did not have callosity at the toe tip or dorsal aspect of the toes. Toe pain during walking was found in 1 case, and a limitation of the shoe-wear was noted in 6 cases. At the final evaluation, 10 cases were graded as excellent, 6 good, and 1 fair. There was no recurrence of the claw toe deformity or limitation of the toe motion. CONCLUSION: Proximal lengthening of the long toe flexor tendons is recommended for treating flexible claw toe deformities. The procedure produced excellent results regarding the deformity correction and pain relief.

Résumé

PURPOSE: The purpose of this study was to investigate and define the factors affecting the success of quad-sparing (QS) minimally invasive total knee arthroplasty (TKA). MATERIALS AND METHODS: A total of 120 patients(150 knees) were tried consecutively to undergo QS minimally invasive TKA from July 2004 to February 2005. Seventy knees (Group 1) could be performed with this technique, but 80 knees (Group 2) were failed and required further incision. Two groups were compared for clinical, radiological and postoperative data. These cases were also divided into three groups according to the time undergone surgery. For these three groups, we analyzed the clinical data and surgical results. RESULTS: Age, height, weight, body mass index and pre-operative knee score were not significantly related to the success of QS minimally invasive TKA. Greater preoperative range of motion, low patella height, and smaller size of the tibial implant were of a significant correlation with the success of surgery. As the number of cases were cumulated, the success rate of this method increased and the operating time was shortened. CONCLUSION: QS minimally invasive TKA could not be successfully applied to every patients. For the success of this surgery, adequate preoperative assessment of the patient and sufficient experience on this surgical technique would be necessary.

Résumé

In vivo electroporation has emerged as a leading technology for developing nonviral gene therapies, and the various technical parameters governing electroporation efficiency have been optimized by both theoretical and experimental analysis. However, most electroporation parameters focused on the electric conditions and the preferred vehicle for plasmid DNA injections has been normal saline. We hypothesized that salts in vehicle for plasmid DNA must affect the efficiency of DNA transfer because cations would alter ionic atmosphere, ionic strength, and conductivity of their medium. Here, we show that half saline (71 mM) is an optimal vehicle for in vivo electroporation of naked DNA in skeletal muscle. With various salt concentrations, two reporter genes, luciferase and beta-galactosidase were injected intramuscularly under our optimal electric condition (125 V/cm, 4 pulses x 2 times, 50 ms, 1 Hz). Exact salt concentrations of DNA vehicle were measured by the inductively coupled plasma-atomic emission spectrometer (ICP-AES) and the conductivity change in the tissue induced by the salt in the medium was measured by Low-Frequency (LF) Impedance Analyzer. Luciferase expression in-creased as cation concentration of vehicle dec-reased and this result can be visualized by X-Gal staining. However, at lower salt concentration, transfection efficiency was diminished because the hypoosmotic stress and electrical injury by low conductivity induced myofiber damage. At optimal salt concentration (71 mM), we observed a 3-fold average increase in luciferase expression in comparison with the normal saline condition (p < 0.01). These results provide a valuable experimental parameter for in vivo gene therapy mediated by electroporation.

Résumé

Direct injection of the vascular endothelial growth factor (VEGF) gene plasmid DNA into the myocardium was shown to induce development of new blood vessels to increase the circulation in the heart of patients with coronary artery diseases. However, such angiogenic gene therapy (via naked DNA) was limited by low level of gene expression. Furthermore, the temporal and spatial characteristics of VEGF gene transfer in the heart are not known. In this study, we demonstrated that a plasmid vector, containing the human cytomegalovirus immediate early (HCMV IE) promoter and enhancer, induces greater expression of gene in the rat heart monitored by gene fused to the chloramphenicol acetyl transferase (CAT) reporter, than four different viral and cellular promoters. Interestingly, expression of VEGF121 protein showed an earlier peak, a shorter duration, and a wider distribution than that of CAT only. Therefore, a plasmid vector with an HCMV IE promoter/enhancer provides clear advantages over other previously developed plasmids. Furthermore, expression profile of VEGF121 gene may provide useful information in the design of angiogenic gene therapy in the heart
