Diabetes is accompanied by delayed wound healing and insufficient granulation tissue formation, possibly because of a defect in fibroblast function. Maintaining glucose level at acceptable low level is considered to be an important part of the clinical treatment of diabetes, but the exact mechanism by which diabetes delays wound repair is not yet known. This study was designed to evaluate the effects of glucose on proliferation([3H]-thymidine uptake) and collagen synthesis([3H]-proline uptake) in dermal fibroblasts from non-lesional skins and chronic wounds. The subjects were divided into 3 groups: non-diabetic control(n = 5), glucose controlled(glycated Hb < 7%) diabetics(n = 5), and glucose uncontrolled(glycosylated Hb > 8%) diabetics(n = 5). The fibroblasts were cultured in two conditions, low glucose(5 mM) and high glucose(20 mM) medium. The data were compared using Mann-Whitney test. The results are as follows: 1. There were no significant differences in the proliferation and collagen synthesis of non-lesional skin fibroblasts in all groups. 2. In high glucose medium culture, the proliferation of the fibroblasts from the wound of the glucose uncontrolled diabetic group was significantly lower than those of the other 2 groups(p< 0.05), and the collagen synthesis of the wound fibroblasts of the control group was significantly higher than those of 2 diabetic groups(p< 0.05). 3. The proliferation and collagen synthesis of the wound fibroblasts in all groups were significantly lower than those of the non-lesional skin fibroblasts(p< 0.05). 4. In the control group and the glucose controlled diabetic group, the proliferation of the wound fibroblasts in the high glucose culture media were lower than those in the low glucose culture media(p< 0.05). Also, in the glucose controlled diabetic group, the collagen synthesis of the wound fibroblasts in the high glucose culture medium was lower than that in the low glucose culture medium(p< 0.05). These results demonstrate that the glucose level may affect the proliferation and collagen synthesis of fibroblasts, and the strict blood glucose control is beneficial to the prevention and treatment of diabetic chronic wounds.

Interventional procedures around the cervical spine have been classically performed under the guidance of fluoroscopy with radiation hazards to patients and doctors. Even though under fluoroscopic guidance, vascular and nerve structures cannot be shown and there are actual risks for the patient. Nowadays, we can use high resolution image ultrasound around cervical spine procedures. Real time imaging is possible. Cervical root block, medial branch block and many other interventions can be performed under ultrasound guidance. In out-patient clinics, ultrasound is very helpful in management of cervical problems in differentiating the origin of pain and treatment for the pain. Ultrasound is radiation free, easy to use and the imaging can be performed continuously while the injectant is visualized in real-time, increasing the precision of injection. Importantly, ultrasound enables visualization of major nerves and vessels and thus leads to improved safety of cervical interventions by decreasing the incidence of injury or injection into nearby vasculature. We therefore performed a review to investigate the feasibility of performing cervical interventions under real-time ultrasound guidance.

Changes of body temperature were observed in the esophagus and rectum by telethermometer during extracorporeal circulation in 40 cases of open heart for detection of significant differences in survivals and non-survivals. The following results were obtained; 1) Esophageal and rectal temperature(just prior to extracorporeal circulation) were 36.4+/-0.69 degrees C, 36.8+/-0.8 degrees C respectively in non-survivals and 36.0+/-0.73 degrees C, 36.4+/-0.8 degrees C in survivals after open heart surgery 2) Normal differences between rectal and esophageal temperature came to disappear after 30 minutes of extracorporeal circulation in two groups. 3) Esophageal temperatures were higher than rectal temperatures after extracorporeal circulation for open heart surgery in both groups. 4) Changes of temperature differences between rectum and esophagus have no correlation with mortality because of the variation in two areas in both groups.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive lymphoma with an overall incidence of 0.04 cases per 100,000 people. BPDCN is a hematopoietic clonal neoplasm that originates from plasmacytoid dendritic cell precursors. A 63-year-old man presented with multiple erythematous nodules over his whole body, including his face, trunk, and both upper and lower extremities that appeared 1 month ago. Skin biopsy showed diffuse dermal infiltration by monomorphic atypical lymphocytes with large, irregular nuclei and scant cytoplasms. Immunohistochemical staining was positive for CD4, CD56, and CD123. The karyotype test showed abnormalities in male chromosomes 47, XY, ＋8 [2]/46, and XY [25], and mutations in DNMT3A, TET2, SRSF2, and ATRX genes were identified in a next-generation sequencing (NGS)-based acute myeloid leukemia gene panel test. The patient was diagnosed with BPDCN and treated with a KALLA 1406 regimen; however, he died on the 17th day of treatment.

Background: Direct immunofluorescence (DIF) is a histochemical technique used to detect tissue-bound autoantibodies and diagnose various immune-mediated skin diseases. Objective: This study aimed to evaluate the sensitivity of DIF for each disorder, and the consistency between clinical, histopathological, and DIF results. Methods: A retrospective study was conducted in 194 patients who underwent skin biopsy and DIF testing at our hospital between January 2011 and December 2021. An antibody panel against immunoglobulin G (IgG), IgA, IgM, C3, C1q, and fibrinogen was used. The concordance rate and κ-coefficient between the clinical, histopathological, and DIF results were evaluated. Results: DIF was observed to be positive in 87 cases; 51 cases of immune-mediated bullous diseases, seven cases of connective tissue diseases (CTDs), 25 cases of vasculitis, and four cases of other diseases. The overall sensitivity of DIF for immune-mediated bullous diseases was 71.8%, which was higher than that of histopathology (64.8%). In CTDs and vasculitis, the overall sensitivities of DIF were 30.4% and 65.8%, respectively, which were lower than those of histopathology (73.9% and 84.2%, respectively). In addition, good concordance among the clinical, histological, and DIF results was observed. Conclusion DIF is a useful diagnostic method, especially for immune-mediated bullous diseases, lupus erythematosus, and Henoch-Schonlein purpura. However, in other CTDs and vasculitis cases, the sensitivity of DIF is relatively low. Therefore, the diagnostic value of DIF along with clinical and histopathological findings will be maximized only when the DIF test is performed for appropriate diseases.

Individual identification procedure is one of the most improtant part in medicolegal fields. Recently, radiolegal investigation methods have been widely applicated to the medicolegal field for the purpose of individual identification. So authors attempted to determine sex and calculate stature by using roentgenographic findings of long bones of 248 subjects the living materials. In orthoscanographic study for long bones, we measured total length, midshaft width, epiphyseal width, cortical width, head diameter of each bones The total length, midshaft width, cortical width, condylar breath, horizontal & vertical head diameter of femur show statistically significant differentiation between two sexes, in tibia, total length, midshaft, cortical width, proximal and distal epiphyseal width show statistically significant. In fibula, Humerus, radius and ulna, total length is only statistically significant. And other wresults are statistically insignificant. Using femoral and fibial lengths (mm) with "Regression Analysis method" in SAS program, we derived the following fomulae. Height (cm)=95.62±0.148×Total length of Femur. (mm) Height(cm)=82.07±0.22×Total length of Tibia. (mm). In conclusion, radiologic measurement of long bone might be one of the useful methods in individual identification of unknown subject in Korea.

Anesthesiologists are faced with a growing number of patients in need of cardiac pacing with symptoms of increasing complexity. Because intraoperative pacemaker malfunction can lead to sudden death, it is important for the anesthesiologists to possessthe information necessary to evaluate and treat such patients. On the other hand, torsade de pointes, a particular form of life-threatening polymorphic ventricular tachycardia, is known to be elicited in patients with cardiac pacemakers in the setting of abnormally long QT intervals, decreased heart rate and severe electrolyte disturbances, notably hypokalemia. We herein report a case of intraoperative torsade de pointes that was triggered by pacemaker malfunction-induced bradycardia in a patient with a VVI-type cardiac pacemaker, whose serum potassium and magnesium level were low preoperatively. (Korean J Anesthesiol 1999; 37: 164~167)

There are many disease entities which are associated with hemoglobinuria but the report of which is very rare during anesthesia except in the case of incompatible transfusion. The authors experienced a case of severe hemoglobinuria during general anesthesia with halothane, nitroud oxide, and thiopental sodium. The patient had no transfusion perioparatively, and no history of hemoltic problems except for prolonged oozing after ethrane anesthesia for tympanoplasty five monthes ago previously. The hemogiobinuria disappeared after two days of corticosteroid therapy, but afterwards the patient suffered from mild hepatitis which seemed to be due to repeated halothane anesthesia.
