PURPOSE: The majority of nasal bone fractures have been managed by routine procedure of closed reduction, intranasal packing or intranasal Kirschner wire (K-wire) splinting. But it leaves rooms for many complaints from patients such as pain, rhinorrhea and nasal obstructioon. Another option is, of course, no packing at all. The study was initiated to assess the necessity to pack or splint the nasal bone after routine closed reduction. METHODS: We analysed the medical records of 35 patients with nasal bone fracture who were operated by closed reduction in the last 2 years. We evaluated the postoperative CT scan scores and external deviation criterias 1 month after the operation. RESULTS: The postoperative deviation criteria and postoperative CT scan score were favorable and there were no serious complications using this technique. CONCLUSION: The present study demonstrates that the use of packing or splinting need not be routine in the majority of cases. The risks and discomforts associated with these procedures can often be avoided.

Twenty-seven consecutive patients who had post-traumatic stiffness of the elbow were treated by operative soft tissue release or by soft tissue release and distraction arthroplasty. The purpose of this study was to describe the method of operation and postoperative management and to evaluate the results in the patients who had operative treatment for the post-traumatic stiffness of the elbow. The type of operative procedure was determined by whether the factors limiting motion were extra-articular (extrinsic) or intra-articular (intrinsic) and by pre-operative radiographic evaluation. The soft tissue release was performed by staged adhesiolysis through lateral or combined lateral and medial approaches. And if the factors limiting motion included a severe intraarticular lesions, distraction arthroplasty using the Judet or Oganesian apparatus was added to soft tissue release. The mean pre-operative arc of active motion was 42 degrees. At follow-up examination, nineteen to sixty-six months postoperatively, the mean post-operative arc of active motion was 103 degrees. There were nine complications (33 percent) in twenty-seven patients. All of them was transient ulnar nerve paresthesia. And we analysed the final results with Mayo elbow performance index for the evaluation of clinical outcome. Twenty-five (93%) of twenty-seven patients had satisfactory result according to Mayo elbow performance index. We conclude arthrolysis with or without distraction arthroplasty is useful for the treatment of posttraumatic elbow stiffness. However, the accurate anatomical knowledge, operative skill, and careful postoperative rehabilitation program were needed in the operative treatment of post-traumatic elbow stiffness.

4.Ruptured Pancreaticoduodenal Artery Aneurysm with Pancreatitis Treated Using Endovascular and Endoscopic Methods
The Korean Journal of Gastroenterology 2021;77(4):194-198
Pancreaticoduodenal artery aneurysm (PDAA) is a rare form of abdominal visceral aneurysm that accounts for approximately 2% of all cases. Most cases of PDAA are associated with celiac artery stenosis (CAS). Regardless of the size, there is a risk of rupture. Therefore, treatment should be performed immediately after discovery, even though the need to treat the accompanying CAS, if present, is controversial. The authors report a case of ruptured PDAA and accompanying pancreatitis treated using endovascular and endoscopic methods without treatment of CAS. A 50-year-old man was admitted to the emergency department of Wonkwang University Hospital with epigastric pain and hypovolemic shock. CT revealed a ruptured PDAA and a large volume hemoperitoneum. Emergency angiography was performed, and angioembolization of the PDAA was performed successfully. Follow-up CT revealed infection and pancreatitis, which were treated by surgical drainage and pancreatic duct stenting with ERCP. Because the degree of stenosis was not severe, it was decided to follow-up the accompanying CAS. After discharge, the patient was followed up without complications.

BACKGROUND: Staphylococci are major nosocomial pathogens and reveal an increase in resistant strains such as methicillin-resistant Staphylococcus aureus. For treatment of infection and prevention of dissemination, rapid and reliable identification methods are required but the conventional bacterial identification and susceptibility tests require at least 24 hours. In this study, we evaluated the polymerase chain reaction (PCR) of the antibiotic resistant genes by comparing with the disk diffusion susceptibility test for the detection of resistance to penicillin, oxacillin and gentamicin. METHODS: A hundred-thirty-five staphylococci including 95 S. aureus and 40 S. epidermidis were from clinical specimens from June to December 2000. Antimicrobial susceptibility tests were done using the NCCLS disk diffusion method. PCRs were performed with primer sets specific for mecA, blaZ and aac(6')-aph(2"). The species-specific PCR was also used to identify S. aureus and S. epidermidis. RESULTS: All four penicillin-susceptible staphylococci were negative for blaZ and 108 of 131 penicillin resistant-staphylococci were positive for blaZ. The concordance rate for PCR of the blaZ gene and penicillin disk diffusion test was 83.0%. 110 of 115 oxacillin-resistant staphylococci were positive for mecA and all five mecA negative oxacillin-resistant strains were positive for blaZ and have the phenotype beta-Lactamase hyperproducer. One of the oxacillin-susceptible S. aureus was positive for mecA. The concordance rate of PCR for the mecA gene and oxacillin disk diffusion test and those of the aac(6')-aph(2") gene and gentamicin disk diffusion test was 95.6% and 97.8%, respectively. CONCLUSTIONS: The disk diffusion tests misdiagnosed 25% of the mecA negative staphylococci as methicillin-resistant staphylococci (MRS) and lost one of the mecA positive strain. We considered that the detection of the mecA and blaZ gene using the PCR was more useful than the disk diffusion test for detection of methicillin-resistant staphylococci.

PURPOSE: Due to the closed and humid condition of the perineal area, wound problems occurring at this site are sometimes complicated, especially following postoperative radiation therapy. Moreover, the anal sphincter is a very important functional structure but reconstruction of the anal sphincter after severe trauma poses a challenging problem to plastic surgeons. In this article, we demonstrate the usefulness of the pedicled gracilis flap in the reconstruction of the perineal area. METHODS: From September 2008 to November 2009, 6 patients, 4 males and 2 females, underwent surgery of the perineal area. The age of the patients ranged from 21 to 62 years (mean age was 48). The mean follow up period was 14 months. In 4 cases, the patient presented with wound problems after postoperative radiation therapy for anal cancer. In 2 cases, the patient presented with traumatic sphincter damage. Only the gracilis muscle was used in the 4 cases and a musculocutaneous flap was used in the 2 cases involving skin defects, respectively. RESULTS: Among the 6 patients, 1 patient underwent hematoma evacuation of the donor site, and 1 patient presented with prolapse of the vaginal mucosa which recovered spontaneously. There were no report of other complications and there were no wound recurrences. Minimal incontinence was observed in all patients who underwent sphincter reconstruction, but all were satisfied with the overall results. CONCLUSION: The gracilis flap is useful in the reconstruction of the perineal area, such as in cases of radiotherapy induced wound problems and sphincter damage following severe trauma, due to its easy accessibility, rich vascularity, and minimal donor site morbidity.

Neurocysticercosis (NCC) by Taenia solium is the most common parasitic infection of the central nervous system involving the cerebrum. However, spinal involvement of NCC is rare. Spinal NCC can cause radiculopathy, myelopathy, cauda equina syndrome, and even paraparesis, depending on its location and size. Spinal NCC may require surgical treatment as a first-line treatment because medical therapy can further aggravate the inflammation due to dead cysts, resulting in clinical deterioration. The current standard therapy for spinal NCC is surgical decompression followed by medical therapy. We experienced a case of widespread thoracolumbar intradural extramedullary cysticercosis involving the spinal canal with cerebral cysticercosis. We report this rare case with literature review.

STUDY DESIGN: Case report. OBJECTIVES: We report a case of widespread lumbosacral subdural abscess in a patient who underwent bee venom therapy. SUMMARY OF LITERATURE REVIEW: Subdural abscess is rare, but has a poor prognosis. Therefore, prompt recognition and appropriate treatment are paramount. MATERIALS AND METHODS: A 54-year-old woman was hospitalized due to severe back pain. Two days previously, she had undergone bee venom therapy. The patient then visited the emergency room because of severe back pain. However, a paraspinal infection was not detected on enhanced magnetic resonance imaging (MRI). Six days after admission, the patient showed signs of meningeal irritation and an emergency cerebrospinal fluid analysis showed typical findings of bacterial meningitis. Although adequate antibiotic treatment was administered, 20 days after admission, the patient's symptoms became aggravated. Pachymeningeal enhancement, myelomeningitis, and subdural abscess compressing the cauda equina were found on enhanced MRI. Thus, laminectomy between L3–L4 and L5–S1 was performed, as well as subdural abscess drainage. Antibiotic agents were applied for 6 weeks after the operation, and resolution of the subdural abscess was identified on follow-up MRI. RESULTS: In this patient, lumbosacral subdural abscess occurred due to bee venom therapy. It was cured by adequate surgical and antibiotic treatment. CONCLUSIONS: Bee venom therapy can cause subdural abscess of the spinal cord. Even if it is a rare case, this possibility is worth consideration in the Korean medical context.
