Staphylococcus aureus is one of most prevalent intramammary pathogens and have characteristics which are not easily eradicated. Recently, to understand the sources and transmission of S aureus, many studies have focused on the subtyping of field isolate. This study was preformed to investigate the distribution pattern and characteristics of the isolates using phenotyping and genotyping. Samples were collected from milk of each udder, cow bodies (perianal region, vagina, tail, udder skin, sole) and environment (floor, liner, milker's hands, water, towel, insect) from 6 herds located in Kyung-gi province. Forty five strains of S aureus were isolated from 3 dairy herds (A, B, C) and were typed by hemolytic pattern, antibiotic resistant pattern, enterotoxin typing and PCR-based DNA fingerprinting. Slime productivity was also compared by each subtype to examine potential infectiousness. Of 45 strains, 41 were isolated from milk samples and 4 were isolated from liners. No strains isolated in the bodies and environment. Forty five strains isolated were classified as 18 subtypes by phenotyping and genotyping. There was common subtype between A and B herd, but the subtype of C herd showed different pattern. Among predominant subtypes, 60% of S aureus strain isolated from A and B herd showed subtype I and 50% of S aureus strain isolated from C herd belonged to subtype VI and X II. Neither somatic cell count (SCC) nor slime production was significantly different between predominant and minor subtypes. In summary, the study revealed that liners play more important roles in the mode of transmission than environmental sources. Several subtypes can be found in a herd, only a few subtype, however, was largely associated with the majority of infection.

Background: Preauricular sinuses represent a common congenital abnormality in children. Classically, a preauricular sinus manifests as a small opening, usually near the anterior limb of ascending helix. The difficulty in the surgical treatment of preauricular sinus is the high recurrence rate. The aim of this article is to review the outcomes of preauricular sinus and to introduce our surgical technique and its prognosis. Methods: A single-institutional retrospective review was performed for all patients who had undergone excision of congenital periauricular sinus between October 2007 and April 2014. Medical records were reviewed for demographic information, wound complication, and recurrence rate. The sinus tract was visualized with the aid of preoperative dye instillation and intraoperative probe insertion. The skin next to the sinus opening was incised elliptically, and the tract itself was dissected medially to the end of the sinus tract and posteriorly to the cartilage of the ascending helix. Results: The review identified 44 patients for a total of 57 preauricular sinus tracts. The mean age at time of operation was 16.3 years with a range from 9 months to 65 years. Unilateral preauricular sinus tract was present in 31 patients (11 right and 20 left preauricular tract), and 13 patients had bilateral sinus tract. None of the patients had experienced wound issues postoperative, and there were no recurrent sinus tract formation or infection. Conclusion: Using a combination of dye instillation, probe insertion, and modified dissection, we were able to achieve a recurrence free series of preauricular sinus tract excision among a heterogenous group of patients. A large patient series is necessary to replicate the results of this study.

Herpes zoster is caused when the varicella zoster virus(VZV) that has remained latent since an earlier varicella infection is reactivated with cutaneous and mucous manifestations. They occur in 20% cases in the trigeminal area and typical manifestations are neuralgias simulating dental pain, also vesicles with an erythematous halo located in the territory of the second and third trigemial branch. They erupt on the skin, the lips, tongue, palate and cheeks. With an ever-increasing number of elderly and immunocompromised patients attending the dentist, the dental profession can expect to encounter an increased number of herpes zoster patients. Furthermore, the oral and maxillofacial surgeons must be familiar with the presenting signs and symptoms of patients experiencing the prodromal manifestations and oral complication of herpes zoster of the trigeminal nerve. As presentation of our patient with ulcer on hard palate caused by herpes zoster, current treatment of herpes zoster and post-herpetic neuralgia are discussed.

Purpose: The purpose of the present study was to compare and analyze the clinical outcomes of the percutaneous and open repair of acute Achilles tendon ruptures. Materials and Methods: We performed a retrospective study on 24 patients (group 1) managed with percutaneous repair, and 21 patients (group 2) managed with open repair for acute Achilles tendon rupture. The postoperative evaluations were done by an Arner-Lindholm scale and AOFAS score. Postoperative overall satisfaction and cosmetic satisfaction were also evaluated. Results: By Arner-Lindholm scale and AOFAS score, there was no difference between two groups (p<0.05). As for postoperative overall satisfaction, 5 cases were very satisfied, 16 cases were satisfied and 3 cases were fair in group 1. In group 2, 12 cases were very satisfied, 9 cases were satisfied. For postoperative cosmetic satisfaction, 13 cases were satisfied, 11 cases were fair in group 1. In group 2, 9 cases were very satisfied, 12 cases satisfied. In open repair group, a case of deep wound infection and three cases of skin necrosis were reported as complication. 2 cases of sural nerve injury were seen in percutaneous repair group and were recovered within 3 months. Conclusion: Percutaneous repair of acute Achilles tendon ruptures have high level of cosmetic satisfaction compared with open repair without any significant difference in clinical outcomes.

Purpose: The purpose of this study was to compare and analyze the results of midfoot arthrodesis with locking plate fixation and the other instruments. Materials and Methods: Twenty one patients, a total of 22 feet who underwent midfoot arthrodesis at our institution were reviewed retrospectively from January 2006 to December 2011. Locking plates were used in 9 cases, and the other instruments such as K-wires, screws, staples were used in 13 cases. Radiologic union time was evaluated and compared between both groups. Preoperative & postoperative AOFAS midfoot scores were evaluated and compared as clinical results. Results: The average AOFAS score was rising from 69.7 to 89.4 in locking plate group and from 67.6 to 80.7 in the other instrument group. There was no statistically significant difference in two groups (p=0.179). The mean radiologic union time was 10.2 weeks in locking plate group, 12.6 weeks in the other instrument group with no significant difference (p=0.062). One case of peroneal nerve irritation was detected as a complication in locking plate group. One case of peroneal nerve irritation and 1 case of superficial wound infection with skin sloughing were detected in the other instrument group. Conclusion: There was no statistically significant difference for union time and clinical results in both groups. A locking plate can be one of the useful option for midfoot arthrodesis.

Purpose: Sacrococcygeal pilonidal sinus is a chronic inflammatory disease that mostly affects young people, which warrants surgical intervention. Although many surgical methods have been suggested, an optimal surgical method remains controversial because of high recurrence rates and postoperative complications. The objective of this study is to evaluate the results of wide excision and coverage with fasciocutaneous advancement flap for the treatment of sacrococcygeal pilonidal sinus, and to assess the usefulness of this method Methods: From May 1995 to October 2006, the authors treated 19 patients with the use of coverage with fasciocutaneous flap after wide excision. The results were evaluated regarding recurrence rates, complications, and the change in sensitivity of the gluteal region after surgery. The follow-up period was 7 to 142 months (mean, 76 months). All patients were male. Results: Postoperative complications were wound infection at the suction drain insertion site and skin necrosis around the suture margin in one case, respectively. During the follow up period, only one recurrence (5.3%) was seen in fifth postoperative month, which was successfully treated by the same operative procedure. There was no other complications such as seroma, hematoma, wound dehiscence and flap loss. Extensive scarring and anatomic distortion did not occur in the reconstructed area. In addition, sensitivity of the gluteal region did not diminish. The aesthetic results were satisfactory for all patients as well. Conclusion: The authors advocate that fasciocutaneous flap closure be a good alternative method to cover defects after the excision of sacrococcygeal pilonidal sinus.

Background CGCryoDerm was first introduced in 2010 and offers a different matrix preservation processes for freezing without drying preparation. From a theoretical perspective, CGCryoDerm has a more preserved dermal structure and more abundant growth factors for angiogenesis and recellularization. In the current study, the authors performed a retrospective study to evaluate freezing- and freeze-drying-processed acellular dermal matrix (ADM) to determine whether any differences were present in an early complication profile. Methods Patients who underwent ADM-assisted tissue expander placement for two stage breast reconstruction between January of 2013 and March of 2014 were retrospectively reviewed and divided into two groups based on the types of ADM-assisted expander reconstruction (CGDerm vs. CGCryoDerm). Complications were divided into four main categories and recorded as follows: seroma, hematoma, infection, and mastectomy skin flap necrosis. Results In a total of 82 consecutive patients, the CGCryoDerm group had lower rates of seroma when compared to the CGDerm group without statistical significance (3.0% vs. 10.2%, P=0.221), respectively. Other complications were similar in both groups. Reconstructions with CGCryoDerm were found to have a significantly longer period of drainage when compared to reconstructions with CGDerm (11.91 days vs. 10.41 days, P=0.043). Conclusions Preliminary findings indicate no significant differences in early complications between implant/expander-based reconstructions using CGCryoderm and those using CGDerm.

Purpose: Mandibulotomy approach and mandible sparing approach are most common methods for oropharyngeal cancer surgery. Good surgical view and convenience of flap inset are advantages of mandibulotomy approach but deformity of mandible contour, postoperative malocclusion and radionecrosis are its limitations. To make up for the limitations, mandible sparing method is commonly performed, but limited surgical view and difficulties of flap inset are the weak points of this approach. The purpose of the study is to compare mandibulotomy and mandible sparing approaches in postoperative complications and progression of the treatment in oropharyngeal cancer operation and reconstruction. Methods: Single reconstructive microsurgeon operated for oropharyngeal cancer patients with different surgeons of head and neck department who prefer mandibulotomy and mandible sparing approach respectively, and we compared the frequency of postoperative complication, operation time, duration of hospitalization and recurrence rate between two different surgical approaches. Results: Mandibulotomy approach was used in 18 patients and mandible sparing approach was used in 15 patients. In mandibulotomy approach, there happened one case of teeth injury and one case of necrosis of skin and gingiva, but there happened no malocclusion and radionecrosis. In mandible sparing approach, there were 3 cases of fistula and 2 cases of infection which are significantly higher than mandibulotomy approach. There were no significant differences between early regional recurrence and duration of hospitalization. Conclusion: In this study we compared two different methods for the surgical approach in oropharyngeal cancer surgery. As mandible sparing approach has difficulties of limited surgical view, it can be used for the limited indications of anterior tongue and mouth floor cancer. Mandibulotomy approach has advantages of good surgical view and convenience of flap inset. In this method preservation of gingival tissue, watertight fashion suture, delicate osteotomy and plate fixation to maintain occlusion are the key points for the successful results.
