It is obvious that the examination of nerve conduction as a diagnostic tool is a relatively new field of interest with a state of still undergoing evaluation and improvement. Problems of technique and interpretation notwithstanding, determination of nerve conduction has progressed to a level where it is now used routinely as a part of the electrodiagnostic examination. The present study has been undertaken to determine the normal range of the motor nerve conduction velocity, distal motor latency, amplitude of the muscle action potentials, sensory nerve conduction velocity, distal sensory latency, amplitude and duration of the sensory nerve action potentials of median and ulnar nerves in healthy Korean. One hundred twenty healthy subjects (sixty male and sixty female) were examined. Their ages ranged from 5 to 69 in years and the subjects were arranged in three age groups of 5–9 years, 10–49 years and 50–69 years. The results obtained were as follows: l. In median nerve, mean values for motor nerve conduction velocity, distal motor latency, and amplitude of the muscle action potantials were 56.57± 4.55 (45.2–69.4) m/sec, 3.02±0.48 (1.6–4.5) msec, and 14.2±5.0 (4–28) mV, respectively. 2. In ulnar nerve, mean values for motor nerve conduction velocity, distal motor latency, and amplitude of the muscle action potentials were 58.60±5.06 (43.5–71.4) m/sec, 2.35±0.50 (1.3–4.1) msec, and 11.7±3.7(4–22) mV, respectively. 3. In median nerve, mean values for sensory nerve conduction velocity, distal sensory latency, amplitude and duration of the sensory nerve action potentials were 63.50±5.63 (53.1–75.9) m/sec, 2.37±0.38 (1.0–3.4) msec, 45.5±16.9 (13–120)u V, and 1.68±0.29 (0.9–2.5) msec, respectively. 4. In ulner nerve, mean values for sensory nerve conduction velocity, distal sensory latency, amplitude and duration of the sensory nerve action potentials were 65.34±5.16 (50.6–78.1) m/sec, 2.09±0.38 (1.3–3.2) msec, 45.6±17.5 (12–118) uV, and 1.54±0.32 (0.8–2.5) msec, respectively. In comparison of the obtained values of two nerves. 5. A significant difference was observed between motor nerve conduction studies of the median and ulnar nerves. 6. A significant difference was observed between sensory nerve conduction studies of the median and ulnar nerves except amplitude of the sensory nerve action potentials. 7. Nerve conduction velocity was significantly faster in sensory nerve than in motor nerve. In comparison of conduction velocities among 3 age groups. 8. Motor nerve conduction velocity of the median and ulnar nerves was slow in age groups of 5–9 years and 50–69 years as compared with that of age group of 10–49 years. 9. Sensory nerve conduction velocity of median nerve was slow in age groups of 5–9 years and 50–69 years as compared with that of age group of 10–49 years, and sensory nerve conduction velocity of ulnar nerve was slow in age group of 50–69 years as compared with that of age groups of 5–9 years and 10–49 years.

The formation of urinary calculi following renal transplantation is rare event with a frequency of less than 5%. Although infection, renal tubular acidosis and cyclosporine-induced hyperuricosuria can predispose toward stone formation in a renal allograft. The modalities of treatment used, were percutaneous nephrolithotripsy, shock wave lithotripsy and chemolysis. We report a case in which a double-J ureteral stent that had been forgotten for 10 years induced staghorn calculi in allograft. The stone was successfully removed by percutaneous ultrasonic nephrolithotripsy through graft renal pelvis.

Aphasia as clinical manifestation of cerebral multiple sclerosis is a rarity. We report here a clinical case of multiple sclerosis complicated by striking motor aphasia. A 11 year old male was admitted with sudden onset of aphasia and quadriparesis following appendectomy under the general anesthesia. A few hour after operation, above symptoms and bilateral pyramidal signs were developed. These findings were fluctuated but slowly remitted. Two weeks later second bout of multiple sclerosis developed, characterized by absent spontaneous speech, quadriparesis, multiple cranial nerve palsies internuclear ophthalmoplegia and bilateral pyramidal signs. The finding of E.E.G. disclosed paroxysmal slow waves in high amplitude on frontal region. Patient was treated with steroids and conservative management. Eleven weeks later, he was discharged with relatively good results.

Perforation of maxillary sinus is a common complication of implant placement in posterior maxilla. The purpose of this study was to evaluate the prognosis of sinus perforated implants placed in partially edentulous maxillae. Eighteen sinus perforated implants in 15 patients were examined for cumulative survival rate, radiographic preoperative bone level, and radiographic marginal bone level change. Twenty-two non-perforated implants in the same patients served as control. The results were as follows; 1. There was no statistically significant difference in cumulative survival rate between sinus perforated implants and non-perforated implants (P>0.05). 2. There was no statistically significant difference in the marginal bone level between sinus perforated implants and non-perforated implants (P>0.05). 3. There was no statistically significant difference in cumulative survival rate according to the preoperative bone level (P>0.05). These results suggests that perforation of maxillary sinus may not affect implant success in posterior maxillae.

PURPOSE: The incidence of stage T1c prostate cancer has been reported to have increased more than any other prostate cancer. To evaluate whether a sextant biopsy is useful for the detection of stage T1c prostate cancer, the detection rates were compared between the sextant and 12-sample needle biopsies, in relation to the prostate volume (PV) and serum prostate specific antigen (PSA) level. MATERIALS AND METHODS: Between January, 1986 and December, 2002, 123 patients who were found to be normal upon digital rectal examination, with negative findings on a transrectal ultra sonography (TRUS) examination and elevated serum PSA (>4ng/ml), underwent either a sextant or 12-sample needle biopsy, under local anesthesia, to detect the presence of prostate cancer. RESULTS: There was no statistically significant difference in the cancer detection rate between the sextant (11/41) and 12-sample (24/82) needle biopsies of the prostate. According to the total PSA level, the detection rates of prostate cancer for the 6 and 12 core groups were 31.6 (6/19) and 22.8% (8/35), respectively, (PSA: 4.1-9.9ng/ml), 23.1 (3/13) and 32.0% (8/25) (PSA: 10.0-19.9ng/ml), and 22.2 (2/9) and 36.4% (8/22) (PSA >or=20.0ng/ml). According to the prostate volume, the detection rates of prostate cancer for the 6 and 12 core groups were 28.6 (2/7) and 31.0% (9/29), respectively (PVor=60ml). Our study did not have the statistical power required to rule out small differences. CONCLUSIONS: These findings imply that a sextant biopsy constitutes a useful method for the detection of prostate cancer.
