A case of torsion of the right cryptorchid testis was herein reported. The patient was 6-year-old boy who was rolled on a staircase and traumatized his right inguinal area. There after painful and tender swelling developed on the area, and it spent 4 days prior to visit our department The involved cryptorchid testis showed dark reddish discoloration and external rotation of 360 degrees and was removed because of no re-establishment of blood supply in spite of detorsion for 30 minutes.

Case 1 was a 55-year-old housewife with the 1-year history of mild recurrent gross hematuria and recent history of massive hematuria following radiation treatment for uterine cancer 7 years ago. Various conservative treatments showed no effect but complete hemostasis was obtained immediately after instillation of 100 ml of 4% formalin solution for 30 minutes under sedation. And to date, there has been no recurrence of hematuria or significant complications for 5 months after the treatment. Case 2 was a 45-year-old housewife with the 3-month history of symptomless gross hematuria following irradiation for a gynecologic malignancy 8 years ago. Complete hemostasis was obtained one day after instillation of 100 ml of 4% formalin solution for 30 minutes under sedation. and to date, there has been no recurrence of hematuria or any complications for 2 months after the treatment. Postradiation vesical bleeding is a very difficult condition to control and may result in total cystectomy and urinary diversion. The treatment by intravesical instillation of formalin solution for the intractable vesical bleeding is simple to perform, shows excellent effect and no significant complications, and is a highly recommendable mode of treatment for massive, uncontrollable vesical bleeding before total cystectomy and urinary diversion.

This study was performed to investigate the factors related to tooth wear. For this study, 78 patients with temporomandibular disorders and 76 dental students without any signs and symptoms of temporomandibular disorders were selected as the patients group and as the normal group, respectively. Preferred chewing side, Angle's classification, lateral guidance pattern, head and shoulder posture wee observed clinically. Electromyographic activity of anterior temporalis and masseter muscle were recorded with BioEMG and occlusal status were recorded with T-Scan . Wear facet area of each tooth was measured from working model of upper arch corresponding to the occlusal status from T-Scan, Wear facet area were measured with planimeter in mm2. Total area were divided into incisal, canine, posterior tooth area. Anterior wearfacet area was incisor area plus canine area, and unilateral area was anterior area plus posterior area. The data collected were analyzed by SAS statistical program and the results of this study were as follows: 1. There was no significant difference between the two groups in total werafacet area, and male subjects showed tendency to have larger area in the normal group but female subjects showed tendency vice versa. 2. There was no significant difference related to preferred chewing side and Angle's classification, however, some difference was observed by lateral guidance pattern. Anterior wear facet area in subjects of canine guidance was the largest in the three subgroups. 3. Subjects with head tilting to right side had larger posterior and total area, and subjects with higher shoulder in right side had larger canine and anterior area than any other subgrous. 4. Electromyographic activity of masseter muscle was more correlated with wear facet area than anterior temporalis muscle, and tooth contact number and force were significantly correlated with wear facet area, but the most important factor affecting tooth attrition was age.

Since the myofascial trigger point(MFTrP) has been described fifty years ago, its underlying pathophysiology has been remained unclear. The diagnosis also depends on the characteristic pain, tenderness and physical findin gs, which is yery subjective. In recent years, some physicians investigated the objective findings of MFTrP, using the pressure algometer and thermography. We investigated the electromyographic findings of MFTrP to evaluate the clinical usefulness of local twitch response(LTR) and sympathetic skin response (SSR), and to evaluate the electrophysiologic characteristics of MFTrP. 21 patients, diagnosed as myofascial trigger point syndrome on upper trapezius and so on, were evaluated for the triggering pain with visual analog scale(VAS), pressure threshold(THpr) using pressure algometer(Dolorimeter), LTP with concentric needle electrode and SSR on the palm. There was a significant negative correlation between VAS and THpr, but no significant correlation with electromyographic findings of LTR. Thus LTR could support the existence of MFTrP electrodiagnostically, but, could not explain the clinically correlated severity of MFTrP. There were only 3 patients showing abnormal SSR, who were all complaining the sympathetic sympathetic symptoms on the affected arm with reffered pain. Even though referred pain to arm and hand existed. SSR was normal because suggested autonomic dysfunction of MFTrP is localized mechanism. Among the 13 patients underwent the trigger point block, 8 patients who showed no residual LTR immediate after MFTrP block, had a great symptomatic improvement of MFTrP in a week, but 5 patients who showed the residual LTR did not, Regardless of complaint of pain and soreness immediate after block, loss of LTR would be predicted as a good treatment result. In some cases, spontaneous EMG activity exist within the 3-4mm sized focus of MFTrP. although the taut band of MFTrP is 3-4cm length and depth. But this focus of MFTrP is a electrophysiologic changes within a muscle, not a structural changes seen by ultrasonography.
