OBJECTIVES: To investigate the common causes of persistent septal deviation in revision septoplasty and to report the surgical techniques and results to correct them. METHODS: A total of 100 consecutive patients (86 males) who had revision septoplasty due to persistent septal deviation from 2008 and 2014 were included in the study. Their mean age was 35.6 years and the mean follow-up duration was 9.1 months. Presenting symptoms, sites of persistent septal deviation, techniques used to correct the deviation, and surgical results were reviewed. RESULTS: The mean interval between primary and revision surgery was 6.2 years. Forty-eight patients received revision septoplasty and 52 received revision septoplasty combined with rhinoplasty. Nasal obstruction was the most presenting symptom in almost all patients. The most common site of persistent septal deviation was middle septum (58%) followed by caudal septum (31%). Correcting techniques included further chondrotomy and excision of deviated portion in 76% and caudal batten graft in 39%. Rhinoscopic and endoscopic exams showed straight septum in 97% and 92 patients had subjective symptom improvement postoperatively. CONCLUSION: Middle septum and caudal septum were common sites of persistent deviation. Proper chondrotomy with excision of deviated middle septum and correction of the caudal deviation with batten graft are key maneuvers to treat persistent deviation.

A key factor in successful application of PBL is creation of good problems. Unfortunately, published collections of problems do not exist for many subjects. Consequently, instructors usually write their own problems and case studies if they want to use problem-based instruction. In this study we proposed principles for creation of PBL problems and presented its example. If effective problems suitable to educational goals are engaged, PBL can be introduced to the first grade medical students who do not have any knowlege about medicine. However, additional factors such as number of faculties and students, budget, availability of learning materials also affect successful implementation of PBL.

The fungus aspergillus can cause a variety of pulmonary disorders. Aspergilloma is a noninvasive aspergillus colonization of virtually any type of preexisting pulmonary cavity or Cystic space. Invasive pulmonary aspergillosis is serious, usually fatal infection in patients being treated with immunosuppressants or who have chronic debilitating disease. Allergic bronchopulmonary aspergillosis is charaterized clinically by asthma, blood and sputum eosinophilia and positive immunologic reaction to aspergillus antigen. Awareness of the radio-graphic and CT findings of pulmonary aspergillosis is important in making the diagnosis of aspergillus-caused pulmonary disorders. In this pictorial essay, we illustrated various radiological findings of pulmonary aspergillosis focused on CT findings correlated with gross pathologic specimens.

Reactions from stinging insects are significant to dermatologists because of the wide variety of clinical presentations from mild local reaction to severe anaphylactic reaction. Although ant sting commonly occurs, it has been rarely reported in the literatures. We experienced a unique case with allergic reactions by the ant of the Cremawgaster iw6w urai vagala, subfamily Myrmicinae, family Formicidea, order Hymenoptera that has not been previously reported.

Spinal cord infarction as a complication of spine surgery occurs rarely. Herein, a case of spinal cord infarction, which developed in a 69 year old woman following posterior decompression and internal fixation for a T11 bursting fracture, is descirbed. The anesthetic induction and intraoperative course were uneventful, except at the end of the procedure, where her blood pressure suddenly dropped from 130/90 to 90/60 mmHg. The patient was aggressively treated with a transfusion and vasopressor, the blood pressure then returned to its usual value within 10 minutes. However, during a physical examination in the recovery room, the patient was found to have flaccid lower limbs, with impaired sensory function below the T8 level. Her cord diameter had increased, and a high signal lesion was observed within the thoracic spinal cord, from T9 to T12 level on T2-weighted MR images, which was diagnosing as a spinal cord infarction, was and showed no improvement despite the immediate and aggressive treatment.

Evaluation of a fever of unknown origin (FUO) is complex. Recently, PET scanning has been approved for screening in FUO evaluation. We treated three cases of FUO associated with increased FDG uptake in the bone marrow of the femur and tibia on the fusion PET/CT; all three had the same pattern of uptake. Bone marrow biopsies revealed mature lymphocyte and histiocyte infiltration and myxoid changes in one case, and cortical bone involvement in another case. The cases were all young females who had fever with neutropenia and relative lymphocytosis that lasted for several weeks and then remitted spontaneously. Even though the results of the studies were not diagnostic, the unique uptake pattern on PET/CT and the histology might be related to the cause of the illness and should be studied further to assess the association with classic FUO.

BACKGROUND: Single or multiple episodes of brief period of ischemia and reperfusion(ischemic preconditioning, IP) have been shown to limit infarct size after a subsequent longer period of ischemia. A considerable number of possible mechanisms has been proposed, however, controversies still remain. Accordingly, we evaluated the effect of four cycles of 5 minutes ischemia and 5 minutes reperfusion(IP) followed by subsequent 30 minutes ischemia(ISCH) and 60 minutes reperfusion using isolated Langendorff-Perfused rabbit hearts. Methods and RESULTS: After a 50-minute recovery phase, parameters of the left ventricular function(LVF) including left ventricular developed pressure(LVDP), contractility and the heart rate were recorded, and ultrastructure was examined. Myosin ATPase activity was determined by measurement of inorganic phosphorus and isozymes of the myosin heavy chain were examined by polyacrylamide gel electrophoresis containing pyrophosphate buffer. The ISCH hearts showed severe to irreversible change of the cardiac myocytes homogenously in contrast to the IP hearts in which changes were not homogenous and irreversible injury was only focal. However, parameters of the LVF were not significantly different between the IP and the ISHC hearts during reperfusion. Myosin ATPase activities were also not significantly different(0.67+/-0.123 micromol/mg protein/h in the IP hearts, 0.56+/-0.172 micromol/mg protein/h in the ISCH hearts, and 0.76+/-0.239 micromol/mg protein/h in the control hearts). Band patterns of the myofibrillar proteins, separated by sodium ddodecyl sulfate-polyacrylamide gel electrophoresis, revealed no differences between the IP, ISCH and the control hearts. Myosin heavy chains in the IP and the ISCH hearts were separated into 3 isozymes, V1,V2and V3in pyrophosphate gel electrophoresis in contrast that the control hearts revealed two isozymes, V1and V2. However, there were no differences in the protein composition and electrophoretic motility between the IP and the ISCH hearts. CONCLUSION: These results indicate that IP could not attenuate the changes in LVF, myosin ATPase activity and myosin isozymes on reperfusion, however, it could attenuate the ultrastructural changes of the cardiac myocytes.
