We experienced four cases of sporotrichosis including three lymphocutaneous type and one fixed cutaueous type. Case 1 was a 6-year old child, affected over the right chin. Case 2 was a 31-year old housewife, affected over the right forearm, Case 3 was a 53-year old housewife, affected over the right forearm and dorsum of right hand. Case 4 was a 19-year old student, affected over the left forearm. Histopathologically, chronic granulomatous inflammation with the neutrophilic ivfiltration and/or central suppuration were observed. Mycologically, typical colonies with moist, wrinkled and rnembraneous surface were cultured except in case 3. All patients were completly cured by oral administration of low dosage of potassium iodide(63. R-lllg) in a short period (50~86 days).

Septic embolism and stroke are serious complications in patients with sepsis and often necessitate urgent surgical intervention to control the source of infection. A 69-year-old man presented with severe pain in his back and left thigh. MRI revealed extensive posterior epidural or subdural abscesses extending from the cervical to the lumbar level, as well as an abscess in the iliopsoas muscle. The patient underwent urgent drainage of the abscesses and decompression of the lumbar spine.Postoperatively, he developed sudden-onset atrial fibrillation and altered mental status. Brain CT showed multiple embolic infarctions. His condition deteriorated due to persistent infection, leading to disseminated intravascular coagulation, acute kidney injury, and septic shock. This case highlights the risk of cerebral embolism and hemorrhagic complications in patients with sepsis who undergo surgery.Early recognition of individuals at high risk and comprehensive perioperative management are critical to reducing the likelihood of such complications.

PURPOSE: This study aimed to provide comparative measurements of the effective dose from direct and indirect digital panoramic units according to phantoms and exposure parameters. MATERIALS AND METHODS: Dose measurements were carried out using a head phantom representing an average man (175 cm tall, 73.5 kg male) and a limbless whole body phantom representing an average woman (155 cm tall, 50 kg female). Lithium fluoride thermoluminescent dosimeter (TLD) chips were used for the dosimeter. Two direct and 2 indirect digital panoramic units were evaluated in this study. Effective doses were derived using 2007 International Commission on Radiological Protection (ICRP) recommendations. RESULTS: The effective doses of the 4 digital panoramic units ranged between 8.9 microSv and 37.8 microSv. By using the head phantom, the effective doses from the direct digital panoramic units (37.8 microSv, 27.6 microSv) were higher than those from the indirect units (8.9 microSv, 15.9 microSv). The same panoramic unit showed the difference in effective doses according to the gender of the phantom, numbers and locations of TLDs, and kVp. CONCLUSION: To reasonably assess the radiation risk from various dental radiographic units, the effective doses should be obtained with the same numbers and locations of TLDs, and with standard hospital exposure. After that, it is necessary to survey the effective doses from various dental radiographic units according to the gender with the corresponding phantom.

PURPOSE: The purpose of this study was to evaluate the clinical efficacy of enhancing deficient interdental papilla with hyaluronic acid gel injection by assessing the radiographic anatomical factors affecting the reconstruction of the interdental papilla. METHODS: Fifty-seven treated sites from 13 patients (6 males and 7 females) were included. Patients had papillary deficiency in the upper anterior area. Prior to treatment, photographic and periapical radiographic standardization devices were designed for each patient. A 30-gauge needle was used with an injection-assistance device to inject a hyaluronic acid gel to the involved papilla. This treatment was repeated up to 5 times every 3 weeks. Patients were followed up for 6 months after the initial gel application. Clinical photographic measurements of the black triangle area (BTA), height (BTH), and width (BTW) and periapical radiographic measurements of the contact point and the bone crest (CP-BC) and the interproximal distance between roots (IDR) were undertaken using computer software. The interdental papilla reconstruction rate (IPRR) was calculated to determine the percentage change of BTA between the initial and final examination and the association between radiographic factors and the reconstruction of the interdental papilla by means of injectable hyaluronic acid gel were evaluated. RESULTS: All sites showed improvement between treatment examinations. Thirty-six sites had complete interdental papilla reconstruction and 21 sites showed improvement ranging from 19% to 96%. The CP-BC correlated with the IPRR. More specifically, when the CP-BC reached 6 mm, virtually complete interdental papilla reconstruction via injectable hyaluronic acid gel was achieved. CONCLUSIONS: These results suggest that the CP-BC is closely related to the efficacy of hyaluronic acid gel injection for interdental papilla reconstruction.

Synovial chondromatosis is an uncommon disorder characterized by metaplastic formation of multiple cartilaginous and osteocartilaginous nodules within connective tissue of the synovial membrane of joints. Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is frequently found in the general skeleton, but is rare in the mandibular condyle. We experienced 2 patients with abnormal appearance of temporomandibular joint. Histologic diagnoses were not obtained, because surgery was unwarranted in view of the lack of symptoms and the benign differential diagnosis. We describes 2 cases that show the characteristics of both disease simultaneously.

Recently, interest has been increased on the role of catecholamines in extrarenal potassium homeostasis. This study has undertaken to investigate the effects of epinephrine added to lidocaine for axillary block in HR, MAP, ABG, blood sugar and electrolytes (Na+, K+), and the effects of propranolol, beta-adrenergic blocker, on the data. The patients admitted to our hospital for operation of upper extremities were divided into three groups. Group I was 10 patients blocked with lidocaine 30 ml. Group II was 14 patients blocked with lidocaine 30 ml with epinephrine 0.3 mg(1:100,000). Group III was 10 patients pretreated with propranolol (10u/kg) and blocked with lidocaine 30 ml with epinephrine. After block, the results were as follows. 1) MAP decreased in all group and group III decreased more than group I. 2) HR increased all group and group III decreased more than group I. 3) ABG showed hypoventilatory pattern due to sedative effect by diazepam (0.15mg/kg). 4) Blood sugar value was increased in group I and II, showed increasing tendency in group III, but this tendency was not significant. 5) Blood K+ concentration decreased significantly and the maximal decrease was 0.5 mEq/L in 30 min after block, but there was not significant decrease in group III. This results indicate that clinical dose of epinephrine(1;100,000) decrease blood K+ concentration significantly and propranolol (10u/kg) pretreatment prevent K+ decreasing effect of epinephrine. In clinical practice, it is suggested that much care must be paid to use of local anesthetics with epinephrine to hypokalemic patients.
