BACKGROUND: The purpose of this study is to compare the radiological and clinical outcomes after open reduction and plate fixation of midshaft clavicle fractures between patients who achieved successful anatomical reduction and those who had a remaining fracture gap even after open reduction and plate fixation, and were thus treated with additional demineralized bone matrix (DBM). METHODS: This retrospective analysis was conducted on 56 consecutive patients who underwent open reduction and internal fixation using a locking compression plate for acute displaced midshaft clavicle fractures, and who underwent radiographic and clinical outcome evaluations at least 6 months postoperatively. The outcomes between those who achieved perfect anatomical reduction without remnant gap (n=32) and those who had a remaining fracture gap even after open reduction and plate fixation treated with additional DBM (n=24) were evaluated. RESULTS: There were no differences in the use of lag screws or wiring and operation time (all p>0.05) between those with and without remnant gap. No difference in the average radiological union time and clinical outcomes (satisfaction and Constant score) was observed between the two groups (all p>0.05). However, significantly faster union time was observed for AO type A fracture compared with other types (p=0.012), and traffic accident showed association with worse clinical outcomes compared with other causes of injury. CONCLUSIONS: Surgical outcome of midshaft clavicle fracture was more affected by initial fracture type and event, and re-reduction and re-fixation of the fracture to obtain a perfect anatomical reduction spending time appears to be unnecessary if rigid fixation is achieved.

BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

A 53-year-old woman presented with dyspnea. She had undergone extended thymectomy for an invasive thymoma two months prior. CT revealed numerous small nodules in the lung. After that, she deteriorated owing to acute respiratory distress syndrome (ARDS), and the vascular surgeon planned veno-venous extracorporeal membrane oxygenation (ECMO). During percutaneous cannulation through the left femoral vein, a vascular injury was suspected, and the patient’s vital signs became unstable. Diagnostic angiography showed a ruptured left common iliac vein, and the bleeding was stopped by placement of a stent-graft. May-Thurner syndrome was diagnosed on abdominal CT. Here, we report a rare case of ECMO-related vascular injury in a patient with an unrecognized anatomical variant, May-Thurner syndrome.

We investigated whether the two variant elements of CRE(TGcCGTCA[5'CRE], TGACcTCA[3'CRE]) in the 5'flanking region of the rat TRH gene, which are different from the CRE consensus sequence(5'-TGACGTCA-3') by one base pair, are responsive to cAMP, and whether the one base pair difference is responsible for the degree of cAMP responsiveness of the gene. When CA 77 cells were stimulated with forskolin and isobutylmethylxanthine for 4 hours, the level of TRH mRNA was increased by only two fold. The transient gene expression study using serial 5'deletion of the TRH gene in PC12 cells showed that the region between-113 and-77, which includes 5'CRE, was crucial for the cAMP resonsiveness. When the plasmid, which contains the 30 bp oligonucleotide including either 5'CRE or 3'CRE ligated to the enhancerless RSV promoter, was transfected into PC12 cells, it did not significantly affect not only the basal transcription but cAMP responsiveness. The 65 bp oligonucleotide including both 5'CRE and 3'CRE, however, increased both of the basal transcription and cAMP-stimulated transcription by 2-3 fold. When the sequence of 5'CRE was converted to that of the CRE consensus by replacing one base pair, the cAMP responsiveness was increased by two fold although the basal transcription was not increased. The one base pair mutant of 3'CRE increased both of the basal and cAMP-stimulated transcription by 3-4 fold. These results suggest that there are the two variant CREs in rat TRH gene, which are relatively weak CRE compared to the CREs of other neuropeptide genes and cooperative for the activation of both the basal and cAMP-stimulated transcription. The one base pair difference of the variant CREs from the CRE consensus sequence is responsible for the weak responsiveness to cAMP.

Dermoid cysts develop from sequestration of epithelium along lines of embryonic fusion.The most common locations are the lateral third of the eyebrows, nose, and scalp. These cysts are located in the subcutis; they are often adherent to periosteum, and may invade or erode underlying bane. A 34-year-old female presented with a solitary, skin colored, dome-shaped, child fistsized, subcutaneous mass on her right occiput. At operation, keratinous material was discharged and tufts of hair projected from opening of the cyst wall.The base of the cyst was firmly adherent to periosteum and diffuse depression with focal deep erosions of the outer table of skull was found.

Photodynamic therapy(PDT) is a treatment modality by highly reactive oxygen intermediates generated through the interaction of light with a photosensiziter. It has been shown to be an effective treatment for various cutaneous and noncutaneous malignancies. It is efficient for the curative and palliative treatment of epithelial skin tumor in situ or early invasive lesions. In effect, it is a useful alternative treatment for the lesions located on anatomically difficult areas or the large-sized lesions. We treated a case of Bowen's disease arising on the plantar area and 3rd and 4th toewebs of left forefoot in a 61-year-old man with PDT using the hematoporphyrin derivative, porfirmer sodium(Photofrin, Russia) as a photosensitizer and gold vapor laser as a visible light source. The outcome showed partial clinical improvement after about 2 months' follow-up.

STATEMENT OF PROBLEM: Screw loosening has been a common complication and still reported frequently. PURPOSE: The purpose of this study was to evaluate abrasion of the implant fixture and TiN coated abutment screw after repeated delivery and removal with universal measuring microscope. MATERIAL AND METHODS: Implant systems used for this study were Osstem and 3i. Seven pairs of implant fixtures, abutments and abutment screws for each system were selected and all the fixtures were perpendicularly mounted in liquid unsaturated polyesther with dental surveyor. After 20 times of repeated closing and opening test, the evaluation for the change of inner surface of implant and TiN-coated abutment screw, and weight loss were measured. Mann-Whitney test with SPSS statistical software for Window was applied to analyze the measurement of weight loss. RESULTS: TiN-coated abutment screws of Osstem and 3i showed lesser loss of weight than non-coated those of Osstem and 3i (P < .05, Mann-Whitney test). CONCLUSION: Conclusively, TiN coating of abutment screw showed better resistance to abrasion than titanium abutment screw. It was concluded that TiN coating of abutment screw would reduce the loss of preload with good abrasion resistance and low coefficient of friction, and help to maintain screw joint stability.

OBJECTIVES: Thyroid cancer patients may experience emotional distress during cancer treatment including surgical operation and radioactive iodine treatment. The aims of this prospective study were to investigate changes of anxiety and depressive symptoms in patients with differentiated thyroid cancer(DTC) under preoperative, postoperative and short-term hypothyroidism state. METHODS: Using the Hospital Anxiety and Depression scale(HAD) and the Distress Thermometer, we sequentially assessed the levels of anxiety, depression and distress in 41 DTC patients at 3 time points such as preoperative state, postoperative state and short-term hypothyroidism state. RESULTS: The HAD-anxiety score was significantly higher in preoperative state(6.93+/-3.97) than postoperative state(4.22+/-2.92) and short-term hypothyroidism state(4.93+/-3.64). Any other significant change in depression or distress thermometer score was not observed. Especially, difference of HADS score between the distress and none-distress groups was significant in preoperative state and post-operative state, but the difference become not significant in the short-term hypothyroidism state. CONCLUSIONS: Induced thyroid hormone deficiency during cancer treatment does not significantly affect emotional distress in patient with DTC. Anxiety and depression in these patients may be associated with distress of the patient before active cancer treatment.
