Purpose: The necrotizing fasciitis is a terrifying infectious disease that can rapidly spreads to surrounding tissues when fascia is infected and it can cause sepsis to death if not properly diagnosed and treated. The purpose of this study is to investigate the characteristics, causes, and treatment methods of necrotizing fasciitis in Korea through reviewing patients admitted to our burn center. Methods: 21 patients with necrotizing fasciitis were selected for this study among those inpatients with electronic medical records (EMR) admitted to Hallym University Hangang Sacred Heart Medical Center from Jan 1, 2008 to June 30, 2019. The medical records and wound photos of those 21 selected subjects were reviewed. Results: There were 13 male and 8 female patients and mean age was 58.76 years old. 13 of 21 subjects were survived and 8 died (38% mortality rate). The surgical treatments performed were I&D, fasciotomy, debridement, allograft, burring, STSG, flap, and amputation. The most common causes were burns in 9 subjects (6 contact burns) and cellulitis occurred on skins in 5 subjects. And other various causes were observed as fournier's gangrene, stab wound, intramuscular injection, tumor and bleu toe syndrome (toe necrosis). The infected areas were 11 feet and legs, 7 hips, 3 abdomen and trunk in 21 subjects. Of the 8 deaths, 3 were infected in feet and legs, 2 were infected in hips, and 2 were infected in abdomen and trunk. As for underlying diseases, 12 patients with hypertension or diabetes were the highest and others such as cancer and stroke were found. Conclusion: The only method to increase the survival rate is to 'suspect' the disease as much as possible and perform early extensive excision. It is advisable to treat the disease by the burn center to properly provide adequate and optimal wound management, infection control, medical care and nutritional supports.
Purpose: This study investigated the adjunctive effect of light-emitting diodes (LEDs) in the treatment of experimental periodontitis. Methods: Experimental periodontitis was induced by placing ligatures around the mandibular second, third, and fourth premolars of 6 beagles for 3 months. After ligature removal, periodontitis progressed spontaneously for 2 months. The animals' hemimandibles were allocated among the following 3 groups: 1) no treatment (control), 2) scaling and root planing (SRP), and 3) SRP with LED irradiation at 470-nm and 630-nm wavelengths (SRP/LED). The probing pocket depth (PPD) and gingival recession (GR) were measured at baseline, 6 weeks, and 12 weeks. The clinical attachment level (CAL) was calculated. After 12 weeks, histological and histomorphometric assessments were performed. The distances from the gingival margin to the apical extent of the junctional epithelium (E) and to the connective tissue (CT) attachment were measured, as was the total length of soft tissue (ST). Results: PPD and CAL increased at 12 weeks compared with baseline in the control group (6.31±0.43 mm to 6.93±0.50 mm, and 6.46±0.60 mm to 7.61±0.78 mm, respectively). PPD and CAL decreased at 12 weeks compared with baseline in the SRP group (6.01±0.59 to 4.81±0.65 mm, and 6.51±0.98 to 5.39±0.93 mm, respectively). PPD and CAL decreased at 12 weeks compared with baseline in the SRP/LED group (6.03±0.39 to 4.46±0.47 mm, and 6.11±0.47 to 4.78±0.57 mm, respectively). The E/ST and CT/ST ratios significantly differed among the 3 groups (P<0.05). The clinical parameters and histologic findings demonstrated that 470-nm and 630-nm wavelength LED irradiation accompanying SRP could improve treatment results. Conclusions: Within the study limitations, 470 nm and 630 nm wavelength LED irradiation might provide additional benefits for periodontitis treatment.

Background: The indications and the optimal time of surgery of infective endocarditis are controversial. We report the surgical results of our hospital during the last 10 years with literature review. Material and Method: Between January 2000 and December 2009, we enrolled 23 infective endocarditis patients who underwent surgery, and analyzed retrospectively. In the preoperative blood culture, 8 cases (34.8%) were positive. The average preoperative antibiotics treatment period was $20.78{\pm}16.00$ days. There were 12 (52.2%) urgent operations. The average follow up period was $49.26{\pm}33.21$ months. Result: 20 mechanical valve replacements were performed, 9 in aortic position, 8 in mitral position and 3 in the both positions. The other procedures were one mitral valvuloplasty, one infected myxoma extirpation, and one infected pacemaker lead removal with debridement. The average period of postoperative intravenous antibiotic treatment was $24.39{\pm}15.98$ days. There were 5 complications, including 2 cases of postoperative bleeding, one postcardiotomy syndrome, one cerebral ischemia, and a low cardiac output syndrome. There were statistically significant postoperative improvement in NYHA class, left ventricle end diastolic/end systolic volume, and left atrium size (p-value < 0.05). Conclusion: We could obtain the satisfactory results without any moftalities by using sufficient preoperative antibiotics in hemodynamically stable patients, and by prompt surgery in unstable patients.
Background: Sternal infection or dehiscence after cardiac surgery through median sternotomy is rare. If suitable treatment is not performed for the complication, however, the mortality is high. For 12 patients with sternal dehiscence or infection, we performed wide excision of the infected and necrotic tissue and covered with muscle flap(s) to obliterate the mediastinal dead space. Material and method: Sternal infection or dehiscence occurred in 13 of patients who underwent cardiac surgery One patient, who died of cerebral infarction before the sternal complication was treated, was excluded in this study. The sternal wound complication occurred in 6 of patients with valve replacement and 6 of patients with coronary bypass surgery, respectively. Since 1991, 9 patients underwent definite surgical debridement and muscle transposition as soon as fever was controlled with closed irrigation and drainage. The necrotic tissue and bone was widely excised and the sternal dead space was eradicated with the single flap or the combined flaps of right pectoralis flap(turnover flap), left pectoralis flap(turnover flap or rotation-advancement flap), and right rectus muscle flap. Result : There was no mortality in 12 patients with coverage of muscle flap(s) for sternal infection or dehiscence The mean interval between the diagnosis of sternal complication and the myoplasty was 6.6$\pm$3.9 days. In 4 patients, one pectoralis muscle flap was used, and in 8 patients both pectoralis muscle flaps were used. For each 1 patient and 2 patients in each group, right rectus muscle flap was added. For the last 3 patients, a single pectoralis flap was used to eradicate the mediastinal dead space and the longer placement of the mediastinal drain catheter was needed. One patient, who had suffered from necrosis of left pectoralis flap(rotation-advancement flap) with subsequent chest wall abscess after coverage of both pectoralis flaps, was managed with reoperation using right rectum flap. Conclusion : Sternal dehiscence or infection after cardiac operation can be readily managed with wide excision of necrotic infected tissue(including bone) and muscle flap coverage after short-term irrigation of sternal wound. The sternal(mediastinal) dead space may be completely eradicated with right pectoralis major muscle flap alone.
Purpose : The importance of meniscal repair is well recognized. But transeciton of the posterior horn of the medial meniscus at the posterior tibial attachment is rarely documented and known irreparable. We experienced 9 cases of transection, and present clinical features and pull out suture technique. Methods and Materials : There were 9cases of transection of the posterior horn of medial meniscus from September 1998 to July 1999 in our hospital. Age was 59.3 years in average and ranged from 38 to 70years. Clinical features and MRI made diagnosis in all cases. We confirmed the diagnosis with arthroscopy and repaired the transection with pullout suture technique. Clinical features : Transection of the posterior horn of the medial meniscus at the posterior tibia attachment occurred frequently in middle aged people. They complained posterior knee pain, but they have no history of definitive trauma. Characteristically they had difficulty in full flexion of the knee and in having a squatting position. MRI is very important in diagnosis of transection, especially in coronal view, there is separation of the posterior horn of the meniscus from the posterior tibial attachment. Surgical technique : Pullout suture technique includes debridement of fibrous or scar tissue, exposure of the subchondral bone of the posterior tibial attachment site, suture the transected end of the meniscus with PDS suture, bone tunnel formation from the anteromedial aspect of the proximal tibia, insertion of wire loop through the tibia tunnel, pull the PDS suture through the tibia tunnel out of the joint and stabilize the PDS with post-tie technique to the proximal tibia. Conclusion : Transection of the posterior horn of the medial meniscus at the posterior tibial attachment is not common clinically and rarely documented. Clinical features and MRI are very important in diagnosis of this type tear. Arthroscopic pullout sutures is useful for treatment of this type tear of the meniscus.
The aim of this study was to investigate the periodontal response according to the timing of orthodontic force application after bone graft into the angular bony defect. Nine dogs were divided into three groups, 2, 4, and 6 weeks, according to the timing of orthodontic force application after bone graft. Periodontal angular bony defects were created surgically at the distal aspect of both maxillary third incisors. Two weeks later, flap operation was performed to eliminate inflammation and reference notch was made on the root surface at the level of the bottom of each defect. Demineralized freeze-dried bone was implanted on the left side whereas only debridement was done on the other side. Experimental tooth movement was executed during 8 weeks on both graft and non-graft sides. After 2 weeks of retention period, animals were sacrificed for histologic specimens. The results were obtained as follows 1 New bone formation was more pronounced in the graft side than in the non-grad side in all experimental animals. 2. In the 6-week group, new bone and cementum formation was observed in more than half from the notch to the cemento-enamel junction, and the zone of connective tissue attachment was found without apical migration of junctional epithelium. 3. In the 4-week group, the amount of new bone formation was smaller than in the 6-week group whereas the overall remodeling pattern was similar. 4. New bone formation was confined to around the notch and the junctional epithelium migrated apically to the level of the notch with no connective tissue attachment and cementum formation in the 2-week group. The results of the present study suggest that periodontal response may be influenced by the timing of orthodontic force application after bone graft into angular bony defect.
Purpose : The purpose was to assess the result of arthroscopic management of the septic arthritis on the knee in compromised patients. Materials and Methods : Fourteen patients with septic knee were analyzed. The mean age was 55 years and the mean follow-up period was 14.6 months. Underlying diseases included 4 cases of diabetes, and history of direct acupuncture in 4 cases. Clinical stage of septic arthritis was judged by $G\ddot{a}chter's$ classification, which was determined by arthroscopic findings. After arthroscopic irrigation and debridement, we observed the results of laboratory data and improvement of clinical findings. Results : Causative organism was identified in 7 cases and no organism was detected in the remaining 7 cases. Stage I was 1, stage II 8, stage III 4, and stage IV 1, respectively. Eleven of 14 cases were improved by one stage operation. Two cases of stage III were recurred and additional arthroscopic management was done. In 1 case of stage IV, symptom was not improved and needed arthrotomy. The result was unsatisfactory in patients with stage III and IV. Serum erythrocyte sedimentation rate and C-reactive protein were normalized after 29.3 and 20.8 days following the operation, respectively. Clinical symptoms disappeared average 2 days following the operation. Conclusion : Arthroscopic management of acute septic arthritis of the knee would be an effective and satisfactory treatment modality in that its postoperative pain and complications are minimal, and it can be done with ease repeatedly.

Bone scan is known to be an effective tool for observing the state of soft tissues and bones of electric burn patients. It is also used for observing the progress of patients after debridement or skin graft as well as deforming to amputate specific body parts. To evaluate bone scan's role in electric burn, we analyzed bone scan 37 patients with electric burn. Among the 37 patients, 8 of 37 were injured in low voltage and 29 of them in high voltage. 27 patients received the electrical input through the hand, 6 through the scalp, 2 through the shoulder, 1 through the left chest wall and 1 through the left inguinal area. Among 29 patients received high voltage, 22 patients had the electrical output through the foot, 3 through the hand, 2 through the shoulder, 1 through the buttock and 1 through the left chest wall. Bone scans revealed cellulitis in 37 patients with 47 sites, osteomyelitis in 15 patients with 15 sites & bone defects in 4 patients with 4 sites. In 4 patients with skin graft or skin flap, follow up bone scan showed improvements of bony uptake in preoperatively bony defect area and all of them were healed without complication. There were 2 cases in which uptake increased in the myocardium, 1 in the liver and 6 in the kidney, however, serum calcium level, EKG, cardiac enzyme, liver and renal function tests were normal. In conclusion, bone scans are helpful in the assessment of injury sites after electrical insult and in differential diagnosis of cellulitis and osteomyelitis. It is also useful tool of assessment after skin graft or skin flap, however, it should be further evaluated about internal organ damage.
Background: Descending necrotizing mediastinitis (DNM) is a serious disease originating in odontogenic or oropharyngeal infection with high mortality despite adequate antibiotics and aggressive surgery. We analyzed results of treatment for DNM. Material and Method: We studied 8 cases diagnosed as DNM from 1998 to 2007. All patients received emergent surgical drainage and debridement with broad spectrum antibiotics just after diagnosis. Antibiotics were changed after bacterial susceptibility testing. The surgical approach included 2 cases of cervicotomy, 6 cases of cervicotomy, and a thoracotomy. Result: The interval between symptom onset and hospitalization was $4.6{\pm}1.8$ days ($1{\sim}9$ day). DNM originated in 4 cases of odontogenic infection (50%), 2 cases of oropharyngeal infection (25%), and 2 cases of unknown origin (25%). Causative organisms were found in 6 cases; Streptococcus in 4 cases, Staphylococcus in 1 case, and Klebsiella in 1 case. The Endo DNM classification was type I (2 cases), IIA (3 cases), and IIB (3 cases). The incidence of thoracotomy was 75%. The surgical mortality rate was 25% (2/8). The cause of death was multiple organ failure caused by septic shock. All mortality cases received only cervicotomy and aggravated infections after initial drainage. Conclusion: Early diagnosis, immediate surgical drainage, and adequate antibiotics, including covered anaerobes, are required. Thoracotomy should be performed with cervicotomy even for localized DNM.
Purpose: Soft tissue defects of the distal lower extremity are commonly accompanied by a fracture of the lower extremities. Theses defects are caused by the injury itself or by complications associated with surgical treatment of the fracture, which poses challenging problem. The reverse superficial sural artery flap (RSSAF) is a popular option for these difficult wounds. This paper reviews these cases and reports the clinical results. Materials and Methods: Between August 2003 and April 2018, patients who were treated with RSSAF for soft tissue defects of the lower third of the leg and ankle related to a fracture were reviewed. A total of 16 patients were involved and the mean follow-up period was 18 months. Eight cases (50.0%) of the defects were due to an open fracture, whereas the other eight cases (50.0%) were postoperative complication after closed fracture. The largest flap measured 10×15 cm2 and the mean size of the donor sites was 51.9 cm2. The flap survival and postoperative complications were evaluated. Results: All flaps survived without complete necrosis or failure. One case with partial necrosis of the flap was encountered, but the wound healed after debridement and repair. One case had a hematoma with a pseudoaneurysmal rupture of the distal tibial artery. On the other hand, the flap was intact and the wound healed after arterial ligation and flap advancement. A debulking operation was performed on three cases for cosmetic reasons and implant removal through the flap was performed in three cases. No flap necrosis was encountered after these additional operations. Conclusion: RSSAF is a relatively simple and safe procedure for reconstructing soft tissue defects following a fracture of the lower extremity that does not require microsurgical anastomosis. This can be a useful treatment option for soft tissue defects on the distal leg, ankle, and foot.
