Background: Transcutaneous Electrical Nerve Stimulation (TENS) has been widely used for pain relief after surgery instead of opioid analgesics therapy. This study was designed to study the effectiveness of TENS on perianal pain after anal surgery. Methods: Forty-eight patients who underwent anal surgery were evaluated in this suudy. Caudal anesthesia with 1.5% lidocaine 30 ml mixture 1：200,000 epinephrine was performed. TENS was done at 100 Hz for 25 min. duration, postoperatively at 4 hrs and 24 hrs. Pain was also measured at the 4 hrs and 24 hrs postoperatively by visual analogue scale (VAS). VAS value were compared before and after TENS application. Results: Values of VAS after TENS were significantly lower compared to those before TENS. Conclusions: From these results, we concluded, TENS may be effective for postoperative perianal pain relief after anal surgery.

Hemangioma is the most common benign tumor of infancy. Greater than 60% of hemangiomas occur on the head and neck, and have an uncomplicated course. In contrast, most complicated hemangiomas develop in the urogenital or anogenital areas. These lesions are frequently associated with pain, bleeding, recurring infections, and ulcerations. Sometimes, perianal ulcerative hemangiomas are difficult to treat with multiple therapies, such as laser and steroid therapy. We managed a case of a severe perianal ulcerative hemangioma in a male newborn who did not respond to conservative management. He was successfully treated after a colostomy.

Caudal narcotic analgesia was assesses after the injection of 3mg morphine diluted in 30ml (physiologic) saline into the sacral canal in 15 Patients after upper abdominal surgery, in 20 patients after lower abdominal surgery under general anesthesia, and in 20 patients after perianal surgery under caudal block. Pain relief was evaluated by the subsequent need for systemic analgesics. All eases had considerable relief from pain an4 the morphine was effective for 12 or more hours. There were no significant differances between pain relief of the upper abdominal and lower abdominal surgery group, upper abdominal and perianal surgery group, and lower abdominal and perianal surgery group (p>0.05, p>0.05, p>0.05). It is suggested that the morphine, which was administered into the sacral, cannal, reached the subarachnoid space and produced it's effect by direct action on the specific opiate receptors in the substantia gelatinosa of th.8 posterior horn cell of the spinal cord. Consequently, whether analgesia from epidural narcotics appears to be segmental in distribution or not is still in controversy.

Phthirus pubis usually infests the pubis, groin, buttocks and perianal region. It can sometimes infest the thighs, abdomen, chest, axillae and beard. Eyelashes and eyebrows may be involved in children. The involvement of the scalp is very rare. We describe a case of P. pubis infestation located exclusively on the scalp in an adult woman. Neither lice/nits nor skin lesions were observed elsewhere, including eyebrows, eyelashes, axillae, pubis, buttocks and perianal region (the patient was hairless in the axillae and pubis). A review of the literature is enclosed.

An epidemiological study was undertaken to estimate the prevalence of Enterobius vermicularis infection among the primary (and infant) school schildren in Ysngyang-gun, Kyongsangbuk-do. During the period from 2 to 14 December 1983, a total of 2,227 school children in 13 schools were examined one time by means of scotch-tape anal swab technique with a simple questionaire study on perianal itching, enuresis and school record. The results are as follows: 1. The overall egg Positive rate was 64.1% and the rate ranged from 46.6 to 86.7% by schools. 2. The egg positive rates of boys and twirls were 60.5 and 68.0% respectively and the difference was statistically significant (P<0.005). 3. There was noted a tendency of decrease in prevalence by increase of the age of children. 4. It was revealed that perianal itching and school record were significantly correlated with E. vermicularis infection (P<0.05) while not in case of enuresis (P>0.1).

A perianal tick and the surrounding skin were surgically excised from a 73-year-old man residing in a southwestern costal area of the Korean Peninsula. Microscopically a deep penetrating lesion was formed beneath the attachment site. Dense and mixed inflammatory cell infiltrations occurred in the dermis and subcutaneous tissues around the feeding lesion. Amorphous eosinophilic cement was abundant in the center of the lesion. The tick had Y-shaped anal groove, long mouthparts, ornate scutum, comma-shaped spiracular plate, distinct eyes, and fastoons. It was morphologically identified as a fully engorged female Amblyomma testudinarium. This is the third human case of Amblyomma tick infection in Korea.

A five-year-old female Yorkshire Terrier dog presented with a perianal mass. Fine needle aspiration revealed that the mass comprised two different types of cells: hepatoid epithelial cells and melanin-containing melanocytes. Histopathological examination confirmed perianal gland adenoma with malignant melanoma. Evidence of metastasis was found on thoracic radiography with soft-tissue densities observed within the pulmonary parenchyma. The dog survived for three months after diagnosis of malignant melanoma. This report describes the clinical findings, diagnostics used, cytological and histopathological findings, and the potential prognosis for a dog diagnosed with malignant anal sac melanoma.

Purpose: The aim of this study was to investigate the clinical features and extraintestinal manifestations (EIMs) of Crohn disease (CD) in Korean pediatric patients. Methods: The medical records of 73 children diagnosed with CD were retrospectively reviewed. Data regarding baseline demographic and clinical characteristics, including CD phenotype at diagnosis based on the Montreal classification, and clinical features and course of EIMs were investigated. Results: Fifty-two (71.2%) of the patients were males. The mean age of the patients was 12.5 years. The mean follow-up period was 3.4 years. The disease location was ileal in 3 (4.1%) of the patients, colonic in 13 (17.8%), ileocolonic in 56 (76.7%). The clinical behavior was inflammatory in 62 (84.9%) of the patients, stricturing in 8 (11.0%), and penetrating in 3 (4.1%). Perianal abscesses or fistulas were found in 37 (50.7%) of the patients. EIMs observed during the study period were anal skin tag in 25 patients (34.2%), hypertransaminasemia in 20 (27.4%), peripheral arthritis in 2 (2.7%), erythema nodosum in 2 (2.7%), vulvitis in 1 (1.4%), uveitis in 1 (1.4%), and pulmonary thromboembolism in 1 (1.4%). Conclusion: Perianal diseases and manifestations were present in more than half of Korean pediatric CD patients at diagnosis. Inspection of the anus should be mandatory in Korean children with suspicious CD, as perianal fistulas, abscesses, and anal skin tags may be the first clue to the diagnosis of CD.

Background: Continuous caudal epidural block is a useful method in postoperative pain control after perianal surgery. But caudal epidural block has the potential of developing adverse effects such as urinary retention. The goal of this study is to evaluate the analgesic and adverse effect of bupivacaine with fentanyl through continuous caudal epidural block in relation to the concentration of bupivacaine. Methods: We divided the patients randomly into two groups. For group I(n=25) postoperative pain was controlled by continuous caudal epidural infusion at the rate of 4 ml/hr of 0.0625% bupivacaine with 3 ${\mu}g$/ml fentanyl: group II(n=14), 0.125% bupivacaine with 3 ${\mu}g$/ml fentanyl, respectively, for duration of 48 hours via epidural catheter. We evaluated pain scores with visual analogue scales at 30 mins, 6 hrs, 12 hrs, 24 hrs and 48 hrs after the operation and the incidence of adverse effect, especially urinary retention, for each group. Results: There were no significant differences in the pain score between group I and II. Urinary retention developed in 9 patients(36%) of group I, and 11 patients (78.6%) of group II. Other adverse effects such as pruritus, nausea, vomiting and respiratory depression developed in few patients. Conclusions: While performing continuous caudal epidural block with mixture of bupivacaine and fentanyl after the perianal surgery, we conclude 0.0625% bupivacaine solution is preferable to 0.125% bupivacaine solution because 0.0625% solution resulted in satisfactory analgesia with minimal incidence of adverse effect.
