BACKGROUND: Present limitations to monopolar RF include the small lesion size, difficulties in targeting, and questions about the reliability.In contrast with monopolar RF, bipolar RF create larger, more predictable, and more extensive ablative lesion. This study documents the optimal spacing of two needles, temperature, and time required to produce bipolar RF lesions. METHODS: Two 20-gauge 5 mm active tip needles and 10 mm active tip needles were secured in a parallel position 6, 8, and 10 mm apart and submerged in egg white that would allow visualization of the size and shape of the lesion.RF lesions were produced at 70, 80, and 90degrees C.At each temperature, photographs were taken at 30, 60, 90, and 120 seconds. RESULTS: When the 5 mm active tips with 6 mm distance were above 60 s and with 8, 10 mm distance above 120 s, continuous strip lesions were produced.10 mm active tips with 120 s were produced too.The others had discrete unipolar lesions around each cannula.The lesion size increased with a higher temperature and time.But time was the more important factor in determining lesion size. CONCLUSIONS: A continuous strip lesion was produced even though the electrode spaced 10 mm apart.And spacing the electrode 6 mm apart with 5 mm active tip and 8 mm apart with 10 mm active tip at 90degrees C for 90 s maximize the surface area of the lesions.

BACKGROUND: Chronic discogenic pain is commonly intractable to various conservative treatments and anatomic correction through operation. Nowadays, a radiofrequency thermocoagualation technique applying the pathophysiologic mechanism that cause discogenic pain and the pathways of transmission of discogenic pain have been successfully tried. This study was performed to evaluate the efficacy of radiofrequecy thermocoagulation of the ramus communicans nerve in patients who suffered from intractable discogenic pain even after intradiscal electrothermal therapy. METHODS: The authors evaluated 13 cases in which radiofrequency thermocoagulation of the ramus communicans nerve was used for patients suffering from chronic discogenic pain even after intradiscal electrothermotherapy. Ten weeks after the procedure, we compared VAS scores of the pre- procedure and post-procedure state. RESULTS: Fifty-four percent of patients had an excellent decrease in the VAS score (VAS < 3). One patient complained of a mild motor weakness of the lower extremity but recovered completely by postoperative day 26. CONCLUSIONS: In the cases of intractable chronic discogenic pain, it is valuable to perform a rhizotomy of the ramus communicans nerve with radiofrequency.

Corneal astigmatism after cataract surgery: The effect of electrocautery. We analized the effect of electrocautery on corneal astigmatism after cataract operation. Phacoemulsification and PCL implantation were performed by standard technique with 5.5 mm scleral pocket incision and sutureless method. In electrocautery group. scleral cautery was done at the site of scleral pocket incision and in no electrocautery group, cautery was not performed. 53 eyes(electrocautery group) showed slight against the rule change(-0.26D +/- 0.72) of corneal astigmatism, while 24 eyes(no electrocautery group) showed slight with the rule change(+0.36D +/- 0.67) of corneal astigmatism at post-operative 2 months. And these difference was statistically significant.(Student's t-test; p=0.019) Therefore, we found the scleral electrocautery at the incision site during cataract surgery induced slight against the rule change of corneal astigmatism.

Radiofrequcy(RF) treatment has a long history, more than hundred years, for the management of chronic intractable pain of various causes. With better understanding of pain mechanism and advancement of technology, along with previous valuable experience, a simpler and safer method of delivering RF thermo coagulation to ideal sites are now available that can be expected to provide more beneficial effects to these patients with chronic disabling pain. This type of treatment will be especially helpful in aged in whom surgery is often contraindicated or highly risky due to medical problems. Here, using up-to-dated, evidence based knowledge and personal experience, authors have tried to introduce briefly the history and basic mechanism of RF technique and various clinical situations where this type of therapy is currently known to be indicated or effective in providing substantial pain relief. In summary, the RF thermocoagulation is proven to be effective way of providing significant pain relief in many chronic refractory pain states with numerous advantages such as minimal invasive, quantitative lesioning with temperature-controlled, well-circumscription of lesions, simplicity and feasibility of procedure, and most of all safety and cost-effectiveness. When it is selected based on careful investigation on type and cause of pain it can be expected to provide relatively long duration of pain relief and also to help to recover functional disabilities from such pain. However, judicious use is warranted because some painful conditions are known to be ineffective or contraindicated from this type of therapy and because there are possible serious complications, although very few. Use of latest technique of pulsed, high-frequency, low-temperatured thermocoagulation will possibly bring hope and new insights in the management of chronic intractable pain of neuropathic in nature. Further research and experience will be required before justifying this type of therapy in appling broader and more challenging situations.

The Harmonic Scalpel made by Ultracision is a system for endoscopic cutting. The energy source is vibration. The power box is attached to a forceps or blade, and the vibrational frequency of the blade approaches 55,500 cycles/second. This causes a knife-like action of the blade through tissue, with enough heating to create coagulation of small vessels. When this vibration energy is applied to the forceps configuration, coagulation occurs. By rotating the bottom blade of the forceps, the instrument becomes like a pair of scissors, and the tissue can divide. The Harmonic Scalpel allows the operator to cut using a tactile tissue. No smoke is created, only microaromized water droplets which are rapidly absorbed by the peritoneak surface. The instrument is extremely safe in that only tissue which is touched is cut; the energy source cannot travel through air, such as can happen with electrosurgery and laser surgery.

Digital mucous cysts are observed frequently on the lateral or dorsal aspect of the digital fingers. Digital mucous cysts are prone to recur after simple excision, electrocoagulation, intralesional injection of corticosteroid and a variety of other therapeutic maneuvers. In this report, we describe one patient with digital mucous cyst who was successfully treated with intralesional injection of 1 mg/ml of minocycline hydrochloride without any sequelae.

Tufted angioma is a benign, slowly progressive angioma with typical histologic findings of small, circumscribed angiomatous tufts and lobules scattered in the dermis. More than 50% of cases occur during the first year of life, but rarely it develops late in life. There was only one reported case of tufted angioma after trauma in the English literature. We report a case of tufted angioma, which developed after electrocautery in a 61-year-old woman showing histologic features of typical tufted angioma.

In the operation room, members of the surgical team have the ultimate responsibility of safe guarding the patient from electrical devices. The electrosurgical unit is one instrument commonly used during surgical procedures. We have experienced accidental burning. Sixty-seven years-old patient received burn at the site of the ECG electrode which was caused by an electrocautery used in conjunction with electronic monitoring equipment. Although cutting and coagulation powers were very low, the normal size of the ECG electrodes led to the generation of a high current density. Prevention of interactions of this kind between properly functioning monitoring and surgical units requires good communication among all members of the operating room team and every electrical instruments should inspected, tested regularly.
