BACKGROUND: Dermatophytosis is sometimes difficult to diagnose deinitively if it has atypical clinical characteristics and mycological tests are negative. Histopathologic findings may be different depending upon the location and causative dermatophytes. OBJECTIVE: The purpose of the present study was to evaluate histopathologic characteristics nf dermatophytosis depending upon the areas of involvement. METHODS: We evaluated the clinical and histopathologic features of 32 cases of dermatophytosis which were diagnosed by skin biopsies at the Dermatology Department of branch hospitals of Catholic University Medical College from March 1985 to August, 1994. Histopathologic features were observed in three dilferent groups divided by location, area of terminal hair, areas of vellus hair and hairless areas. RESULTS: Epidermal changes including hyperkeratosis, parakeratos, acanthosis, spongiosis and neutrophilic exocytosis were frecuently observed in the three groups of Iermatophytosis. In 7 cases of tinea capitis and linea barbae, follicular and inflamma or changes of the deep dermis were important. Hyphae and spores were observed in 71%(5 cases) and 57%(4 cases) respectively, in the follicles. In 19 cases of tinea faciale, tiriea corporis and tinea cruris, change epidermis and superficial dermis as well as findings of follicular infundibulum were important. Herphae were observed in 84%(16 cases) and 53%(10 cases) in the stratum corneum and vellus hir follicle respectively, and in 3 cases the hyphae were observed only in the vellus hair follicle. Sandwich sign, known to be important clue of dermaliophytosis, was observed in only 5%(1 cacse, In 6 cases of tinea manus and linea pedis, hyphae and spores were rebserved in 100% (6 cases) and 33%(2 cases) respectively, in the stratum corneum. CONCLUSION: We consider tha histopathologic observations may of great help to diagnose some difficult cases of dermatophytosis and the presence of hyphae n .he vellus hair follicle may be a more frequent and important finding than the sandwich sign the dermatophytosis of the vellus hairy regions.

A case of calcifying synovial sarcoma, occuring in the deep muscle fascia of the left thigh is reported. The presence of extensive calcification in synovial sarcoma is a favorable sign for prognosis. The patient was a 31-year-old female. The tumor mass had been present for 3 years, accompanying local tenderness. X-ray revealed a soft tissue tumor with central calcification, which was located between the adductor magnus and brevis of the left thigh. The tumor size was 7 x 5.5 cm. There was no connection with the knee joint or the femur. Grossly, the tumor was a relatively well circumscribed hard tumor with massive calcification. Microscopically, the tumor was composed of predominantly spindle cells with accompanying hyalinization, numerous spherical concretions and ossification. The epithelial component was not clearly noted. Mitotic figures were rarely noted in the densely cellular area. Immunohistochemical staining for EMA, S-100, vimentin, and carcinoembryonic antigen was negative while vimentin and cytokeratin were weakly and focally positive. EM study revealed multiple desmosome-like calcification intercellular junctions with a slit-like lumen and an incomplete basal lamina, which suggest that tumor show these cells were undergoing epithelia] differentiation. Above evidence suggest that this tumor is a synovial sarcoma associated with a large area of calcification, a so called calcifying synovial sarcoma. No recurrence was noted in one and half years of follow up.

We experienced a case of unilasteral vocal cord paralysis following cuffed endotracheal intubation for abdominal surgery. The patient had have no laryngotracheal symptoms prior to the operation and anesthesia was uneventful. He complained of hoarseness post-operatively but no visible evidence of trauma secondary to the intubation was mainfested on the indirect laryngoscopic examination, except left vocal cord paralysis. There were no obvious causes for the vocal cord paralysis and possible etiologic factors. Therefore, no specific treatment was done except for the bed rest, humidification and gurgling. Vocal cord function returned nearly normal after six months.

Gastric emptying in patients after several upper gastrointestinal surgeries was studied using the acetaminophen method. The subjects consisted of 23 gastric cancer patients, 2 duodenal ulcer patients, 5 periampullary cancer patients and 4 normal subjects. As an indicator of the gastric emptying rate, the serum acetaminophen concentration was measured by fluorescence polarization immunoassay, in units of g/ml, at 0, 30, 60, 120, and 180 minutes after ingestion of a liquid meal with 1.5 g of acetaminophen. In the normal subjects, the acetaminophen concentrations were 0, 16.35+/-5.06, 18.71+/-5.58, 16.38+/-4.82, and 11.09+/-3.62 g/ml at time 0, 30, 60, 120, and 180 min, respectively. The concentration peaked at 60 min after ingestion of the test meal in the normal subjects. We observed significant delayed gastric emptying after pancreas preserving pancreaticoduodenectomy (PPPD) and a standard Whipple's operation in the early postoperative period. In all patients with a subtotal gastrectomy, a truncal vagotomy was done. However, in patients with a pancreaticoduodenectomy, the vagus nerves were preserved. The gastric emptying pattern was different between the patients with a subtotal gastrectomy and the patients with a pancreaticoduodenectomy, despite similar reconstructions of the gastroenterostomy (Billroth I or Billroth II type reconstruction). There was more rapid gastric emptying in patients with a truncal vagotomy and pyloroplasty than in the normal subjects. Hence, we speculate that the truncal vagotomy was the main cause of the different gastric emptying between the patients with a pancreaticoduodenectomy and the patients with a subtotal gastrectomy.

PURPOSE: This study was aimed to identify whether total mesorectal excision (TME) is a valid prognostic factor for recurrence following curative surgery for rectal carcinoma. METHODS: For 110 high-risk rectal carcinoma patients, recurrence rate and patterns of recurrence were compared between patients undergoing TME and those with classical dissection. RESULTS: Both local recurrence and distant metastasis were significantly lower in TME group than those in classical dissection group. Time interval from operation to the initial recurrence was also significantly delayed in TME group. By comaparing with other prognostic variables, TME was found to be a significant prognostic factor for the recurrence. CONCLUSIONS: We think TME is an important prognostic factor for the recurrence following curative resection in rectal carcinoma.

BACKGROUND: The purpose of our study was to evaluate the functional and radiologic outcomes of additive augmentation sutures through rotator cuff for proximal humeral fractures stabilized locking plate in elderly patients. METHODS: We enrolled 74 patients over the age of 60 years who received internal fixation using locking plates for proximal humeral fractures. Of these, 50 patients had additive augmentation sutures through rotator cuff. The mean age at the time of surgery was 72.1 years (range, 60-89 years), and the mean follow-up period was 17.5 months (range, 12-62 months). The humeral neck-shaft angle and humeral head height were used as radiological markers to assess the effect of additive augmentation sutures through rotator cuff. We allocated the patients who received additive augmentation sutures into group A and those who did not into group B. RESULTS: At the final follow-up, the mean Korean Showlder Society score and Constant scores were 88.96 +/- 12.1 and 86.6 +/- 11.9, respectively, in group A and 86.21 +/- 11.8 and 85.3 +/- 11.7, respectively, in group B (p=0.368, 0.271). At the final follow-up, the mean loss in humeral neck-shaft angle from the time of immediate postoperative measurement was 1.6degrees in group A and 4.8degrees in group B, whereas the mean loss in humeral head height was 0.82 mm in group A and 0.52 mm in group B (p=0.029, 0.178). CONCLUSIONS: The surgical outcomes of internal fixation using locking plates for proximal humeral fractures were clinically and radiologically good in elderly patients over the age of 60 years without any observable complications. Further, the loss of humeral head shaft angle at the final follow-up from its initial postoperative measurement was significantly smaller in patients who received an additive augmentation suture than in those who did not. Thus, we conclude that augmentation sutures are a beneficial option for elderly patients that clinicians can consider at the time of surgical decision making.

10.Is stopping of anticoagulant therapy really required in a minor dental surgery?: How about in an endodontic microsurgery?.
Restorative Dentistry & Endodontics 2013;38(3):113-118
Nowadays, oral anticoagulants are commonly prescribed to numerous patients for preventing cardiovascular accident such as thromboembolism. An important side effect of anticoagulant is anti-hemostasis. In a major surgery, the oral anticoagulant therapy (OAT) regimen must be changed before the surgery for proper post-operative bleeding control. However, in a minor dental surgery and endodontic surgery, the necessity for changing or discontinuing the OAT is open to debate. In this study, risks of the consequences were weighed and analyzed. In patients who stop the OAT, the occurrence of thromboembolic complication is rare but the result is fatal. In patients who continuing the OAT, post-operative bleeding can be controlled well with the local hemostatic measures. In the endodontic surgery, there are almost no studies about this issue. The intra-operative bleeding control is particularly important in the endodontic surgery because of its delicate and sensitive procedures such as inspection of resected root surface using dental microscope and retrograde filling. Further studies are necessary about this issue in the viewpoint of endodontic surgery.
