Perifolliculitis capitis abscedens et suffodiens is a rare chronic recalcitrant follicular disorder which clinically presents itself as pulstules, nodules, intercommunicating abscess and sinuses that leave atrophic, hypertrophic or keloidal scars. Although the etiology of this of condition is unknown, its association with acne conglobata and hidradenitis suppurativa, collectively termed the follicular occlusion triad, suggest a cammon basic pathogenic mechanism of follicular retention. The therapeutic problem is reflected in the variety of therapies that have been tried with varying degrees of success. We report a case of a 34-year-old man who showed a patch of alopecia on the vertex of his scalp. Clinically, the scalp showed multiple soft fluctuant elevated nodules with nonscarring alopecic patches. We performed a treatment with isotretinoin(13-cis-retinoic acid) during 6 months. The patients clinical appearance was much improved and local recurrence and hair loss have not been observed to date.

From Mar. 1985 to Dec. 1992, 170 cases of osteosarcoma, which were proved histologically were admitted in our department at least one time. Among them we analysed 89 cases of Ennekings stage IIB who took limb-salvage(54) or amputation(35) and followed our protocol, with non-randomized retrospective study. The average age of the 89 patiens was 17.0 years(7 to 57). Fifty-four cases of salvage group took neoadjuvant chemotherapy, 35 cases of amputation group took neoadjuvant or adjuvant chemotherapy. The result revealed prevalences of 2/54, 0/35 as to local recurrence; 15 of 54, 17 of 35 as to metastasis; 14 of 54, 15 of 35 as to death. Of the 2 patients who had a local recurrence, one died of metastasis and the other was lost follow up. According to Kaplan-Meier's plot 5-year continuously disease free survival rate for whole 89 cases of stage IIB was 43.1%, for salvage group 56.4%, for amputation group 34.0%. There were no signifcant difference in survival rate between salvage and amputation groups(p>0.05, by log-rank test). This result means the limb-salvage operation for Enneking's stage IIB osteosarcoma does not hinder patients survival.

BACKGROUND: A number of factors can cause dark circles around the eyes including excessive pigmentation, thin and translucent lower eyelid skin overlying the orbicularis oculi muscle, and shadowing due to skin laxity and tear trough. Autologous fat graft is an effective method for the treatment of lower lid dark circles, but irregularities caused by leaving visible lumps of the fat can occur. Tonnard et al. suggested 'nanofat' grafting and introduced its characteristics and clinical applications. The authors used their nanofat grafting to correct lower eyelid dark circles. METHODS: Nanofat grafting was performed in 19 patients for dark lower eyelids. The grafts were injected into subdermal layer using blunt cannula. Microfat grafting with nasojugal fold was performed to all the patients. Among them, 18 patients received transconjunctival fat removal at the same time. RESULTS: All the patients showed much improvement from preoperative dark coloration. There were no visible lumps of fat, contour irregularities, or fat necrosis. Postoperative edema and ecchymosis were minimal. CONCLUSIONS: Nanofat grafting methods provide a good alternative for correcting dark circles by augmenting thin skin with lower complications. This simple, cost effective procedure is suitable for correction of dark circles and various skin rejuvenation purposes.

BACKGROUND: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a “knot-ache”. This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. METHODS: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. RESULTS: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. CONCLUSIONS: The knots of suture anchor maybe a possible etiology of the pain, which we termed a “knot-ache”. Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, “knot-ache”. Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

Cyclodestruction is generally achieved by applying thermal energy across the intact sclera. Commonly employed modalities are ultrasound, cryopexy, diathermy, noncontact laser light and most recently, contact transscleral laser using argon, krypton and Nd:YAG, diode laser. This study was performed to compare the pressure lowering and tissue effects of contact transscleral cyclophotocoagulation(TSCPC) with diode laser using G prode to cyclocryotherapy in rabbit. The results of this study demonstrate a similar intraocular pressure lowering effect of both cyclocryotherapy and contact TSCPC with diode laser using G prode. Histologic studies showed that both TSCPC and cyclocryotherapy are effective anatomic cyclodetructive modalities but in case of TSCPC, less severe destruction of ciliary body was noted. This study indicated that contact TSCPC with diode laser using G probe delivery provieds effective and safe management for eyes with medically and surgically uncontrolled glaucoma compared to cyclocryotheraphy.

BACGROUND: The purpose of this study was to evaluate the efficacy of caudal epidural steroid injection with local anesthetic for chronic lower back pain patients. METHODS: The 152 patients with lower back pain were selected for the study. The patients were treated with the caudal injections of steroid (triamcinolone acetate 40 mg) and local anesthetics (1% lidocaine 17 ml). The efficacy of caudal injections was assessed with the visual analogue scale (VAS) before procedure and at 8 weeks following procedure. RESULTS: The VAS scores of 'Before procedure' group and '8 weeks after procedure' group were 62 23 and 31 15, respectively. The caudal steroid injections provided effectiveness in treating various lower back pain diseases except postlaminectomy syndrome. CONCLUSION: We consider that caudal epidural injections of steroid and local anesthetics are effective for patients with chronic lower back pain in the short term.

Cryosupernatant which is the residual plasma fraction after removing cryoprecipitate has been used for plasma exchange in thrombotic thrombocytopenic purpura and hemolytic uremic syndrome replacing the fresh frozen plasma. Recently, the unusually large yon Willebrand factor multireefs (ULvWFM) has been observed in patients with refractory or chronic relapsing hemolytic uremic syndrome as well as thrombotic thrombocytopenic purpura which disappeared by infusion or plasma exchange with cryosupernatant, and infusion of fresh frozen plasma, the largest multimers of yon Willebrand factor were replenished that it might be a cause of refractoriness. This study was conducted to investigate the characteristics of home-made cryosupernatant from thawed fresh frozen plasma and its thehrapeutic effect in a hemolytic uremic syndrome patient. The level of fibrinogen, coagulation factor VIII, vWF antigen, and ristocetin cofactor activity was decreased and yon Willebrand factor multimers were barely seen in cryosupernatant than those of in fresh frozen plasma. A hemolytic uremic syndrome patient tried with exchange and infusion of cryosupernatant showed excellent recovery. It is concluded that home-made cryosupernatant shares many of the features of fresh frozen plasma except factor VIII, especially von Willebrand factor multimers, and thus it could be a useful alternative to fresh frozen plasma in case of refractory hemolytic uremic synydrome.

Brunners gland adenoma is a benign epithelial tumor of the duodenum originating from submucosal Brunners gland. This is an extremely rare entity that account for only 10.6% of benign duodenal tumor, which are themselves relatively rare, representing 0.008% of all surgical and autopsy specimens. The clinical manifestation are nonspecific gastrointestinal complaints, such as bloating or epigastric pain, and the tumor gives rise to melena or anemia, due to the ulceration or erosion of the tumor. The diagnosis is usually made by radiologic studies and gastroduodenal endoscopy which can also provide definitive treatment. The aim of treatment is complete removal of the lesion and exclude malignancy. We report on 4 cases of Brunners gland adenoma which was confirmed by operation or endoscopic polypectomy.

PURPOSE: The aim of this study was to determine the usefulness of ultrasonography for lumbar anatomical structure measurement. MATERIALS AND METHODS: From January 2011 to April 2011, 41 patients (22 males, 19 females) with back pain who visited the outpatient department and underwent lumbar magnetic resonance imaging (MRI) were selected. In each level of L4 and L5, we measured the longest distance and horizontal distance between each inferior articular process based off a spinous process. We also measured the distance between the spinous process tip and the vertebral body posterior surface and the thickness and width of the multifidus muscle. All distances were measured with ultrasonography and MRI and the two measurement results were compared. RESULTS: Using ultrasonography and MRI, we measured the distance between the spinous process tip and the posterior surface of the body. The distances were 39.16+/-8.71 mm/39.53+/-6.01 mm at L4 and 38.32+/-9.66 mm/37.74+/-10.54 mm at L5. The right multifidus muscle thickness measurements were 32.13+/-10.79 mm/33.84+/-9 mm at L4 and 31.32+/-10.04 mm/32.84+/-12.28 mm at L5. The measuring distance between the spinous process center to the posterior vertebral body surface and thickness of multifidus muscles by ultrasonography and MRI had significant correlations (p<0.05). CONCLUSION: Limitations still exist in measuring the structure of lumbar anatomy with ultrasonography. However, measuring the distance between the spinous process center to the vertebral body posterior surface and multifidus muscle thickness was effective.
