PURPOSE: An ingrown nail is common in military trainees who are exposed to highly demanding activities. Although the matrixectomy procedure has been the main treatment modality, several drawbacks may follow after the procedure, such as infection, periostitis, and continued pain that causes a delayed return to duty. This study examined the outcomes of a simple partial nail extraction with the hypothesis that this procedure may bring an earlier return to duty, lower the perioperative complications, and produce a comparable recurrence rate. MATERIALS AND METHODS: The medical records of patients who had surgical treatment for an ingrown nail in the authors' institution between April 2016 and December 2017 were reviewed retrospectively. Under the inclusion and exclusion criteria, 28 patients with a simple partial nail extraction (group A) and 29 patients with a partial nail extraction with matrixectomy (group B) were investigated. As the clinical outcome, the visual analogue scale (VAS) and satisfaction score, time to return to duty, complications, and recurrence rate were checked and compared between the groups. RESULTS: The VAS scores of group B were significantly higher during the first (p<0.001) and second (p=0.026) follow-up week than group A. The time to return to duty was shorter in group A (7.8 days) than group B (10.1 days), and this difference was significant (p<0.001). Group B had five patients with complications, whereas group A had none (p=0.028). No differences in the recurrence rate (p=0.197) and patient satisfaction (p=0.764) were found between the groups. CONCLUSION: In this study, simple partial nail extraction in military trainees resulted in lower postoperative pain, lower complication rates, and earlier return to duty than the procedure with matrixectomy. Military trainees are temporarily exposed to highly demanding activities. Thus, a satisfactory outcome would be expected with simple partial nail extraction without performing a radical procedure, such as a matrixectomy.

Understanding anatomic variations in neurovascular structure inside the femoral triangle is crucial for regional anesthesiologists performing femoral nerve block. During routine dissection of a cadaver, an ascending branch of the lateral circumflex femoral artery with an anomalous course passing through the femoral nerve, specifically the posterior division, was identified inside the femoral triangle on the left thigh. The novel variation identified in this study occurred in an early stage of prenatal development. Recognition of this anatomic variation will be helpful for reducing unexpected complications during the femoral nerve block and the tensor fascia latae flap. Penetration of the posterior division of the femoral nerve by the arterial branch might cause pain or paresthesia of the medial aspect of the leg in the distribution of the saphenous nerve.

Flightdeck behaviour and flight safety are influenced by the national, organizational, and professional cultures of crewmembers. National complexity of the operating environment ensure that error will be an inevitable occurrence. The influences of three cultures that are relevant to the cockpit are described; the professional culture of the pilots, organizational cultures, and the national cultures surrounding individuals and their organizations. This study review the cultural difference of crewmember in Korea based on Hofstede and Helmreich study. The study concludes with a suggestion of CRM in Korea as strategy necessary for a safety culture considering the multi-cultures cockpit.

BACKGROUND: Aconitium species have been used for a material of oriental herb medicine for analgesic and anti-inflammatory effects. But Aconitium species were known to have the potent poisons like aconitine, mesaconitine and hypaconitine which are of C19 diterpenoid alkaloids. The intoxication symptoms are nausea, vomiting, discomfort and cardiac arrhythmias which are well known as a main cause of death. METHOD AND MATERIALS: We obtained the specimens from the five poisoned cases and analyzed those specimens by GC/MS-SIM for 2002-2004. These cases were divided into two groups. The first group was the victims who ingested raw Aconitium roots and leaves and were all dead. The second was those who ingested processed Aconitium roots. One of them drank Aconitium root-submersed alcohol (root wine) and died. Another victim had ingested some liquid extract of herb medicine for three months but the person's symptom was manifested by jaundice and hematuria without fatality. RESULTS: Autopsy pathology on the cases of raw Aconitium ingestion and root wine drinking revealed similar gross and microscopic feature. The benzoylaconine analogues were detected in root wine (dead case) and hypaconitine, benzoylmesaconine and benzoylhypaconine were detected in herb liquid (living case). The aconitine analogues are hydrolyzed to make less toxic benzoylaconine analogues but the toxicity of hydrolyzed products and the methods of detoxification are still in controversy. CONCLUSION: We could conclude that benzoylaconine is relatively more toxic than benzoylmesaconine and benzoylhypaconitine. And the hypaconitine is relatively less toxic than aconitine and mesaconitine.

Brentuximab vedotin (BV), a potent antibody-drug conjugate, targets the CD30 antigen. Owing to the remarkable efficacy shown in CD30-positive lymphomas, such as Hodgkin's lymphoma and systemic anaplastic large-cell lymphoma, BV was granted accelerated approval in 2011 by the US Food and Drug Administration. Thereafter, many large-scale trials in various situations have been performed, which led to extensions of the original indication. The aim of this review was to describe the latest updates on clinical trials of BV and the in-practice guidance for the use of BV.

The knowledge of arterial patterns of donor and recipient sites is very important for performing a flap surgery. In order to perform a flap surgery using the rectus abdominis muscle knowledge of the distributions, tributaries, and anastomoses of the inferior epigastric artery is necessary. The aim of this study was to establish the clinical and anatomical characteristics of the inferior epigastric artery for flap surgery in Koreans. Sixteen fresh cadavers were injected bilaterally with a radiopaque dye solution through the brachial and popliteal arteries, radiographic images were obtained after the anterior abdominal wall was removed surgically. Subsequently, the anterior abdominal walls of the cadavers were dissected and measured by using metric and non-metric methods. In a majority of the cadavers (83.9%), the inferior epigastric artery had only one main stem. Between the umbilicus and the xiphoid process, the most common type of the anastomosis was multiple anastomoses (Type IV, in 32.1% of the cases), followed by no anastomosis (Type I) and single anastomosis (Type II) in 25% of the cases, respectively. The intramuscular branch of the inferior epigastric artery originated from below the umbilicus in 60.7% of the cases and above it in 39.3% of the cases. The peritoneal branch was further divided into 3 types: lateral, medial, and umbilical. One of them coexisted with other branch of specimen. The peritoneal branch commonly originated from the intramuscu-lar branch. The perforating branch, with an external diameter of greater than 0.5 mm, was clinically significant, was dis-tributed around the umbilicus. The number of arterial branches directly perforating the rectus abdominis muscle was greater than that of those traveling anteriorly. The results of this study may enhance the anatomical knowledge of clinicians with respect to flap surgery or surgical treatments involving the anterior abdominal wall.

OBJECTIVE: To identify the thickness of gastrocnemius muscles (GCM) in normal children and children with spastic cerebral palsy using ultrasonography and to determine the influencing factors in order to increase the accuracy of intramuscular injection of botulinum toxin A. METHOD: Fifty-six children with spastic cerebral palsy (Group A) with no fixed contractures or operation history were involved in this study and they were compared with normal children (Group B). Children lay prone and one examiner measured the thickness of medial and lateral GCM using ultrasonography. Relationship between GCM thickness and clinical variables (age, height, weight, body mass index (BMI), calf circumference, Gross Motor Function Classification System (GMFCS) level, spasticity, number of botulinum toxin injections) were determined with Pearson's correlation. RESULTS: The thickness of medial and lateral GCM were 78.06+/-14.66 mm, 66.90+/-12.23 mm respectively, in Group A, and 103.44+/-12.04 mm, 79.95+/-9.76 mm respectively, in Group B. Medial GCM were thicker than lateral GCM in both groups. The age, height, weight, BMI, calf circumference and the thickness of GCM were higher in Group B. In group A, weight, BMI, calf circumference showed positive correlations with the thickness of medial GCM and GMFCS showed negative correlation with the thickness of medial GCM. CONCLUSION: To increase the accuracy of intramuscular injection of botulinum toxin A, we should keep in mind that the thickness of GCM may be influenced by several factors. Further controlled study including larger group is needed.

OBJECTIVE: The authors present a retrospective analysis of the long-term recurrence rate for the 79 craniopharyngima patients surgically treated between Jan 1989 and Dec 1999. METHODS:Tumor recurrence rates were analysed with respect to age of patients, symptom duration, tumor size, localization of tumor, morphology of tumor, the extent of surgical resection, pathologic diagnosis and the other treatment modalities. RESULTS: For 79 patients, with a mean follow-up period of 5 years, the overall recurrence rate was 29%. Factors associated with decreased risk of recurrence was gross total tumor resection(p=0.01). Subtotal resection was associated with increased risk of tumor recurrence. The adjuvant radiation therapy was revealed efficient not in decreasing recurrence rate but in the delay of tumor recurrence time(p=0.05). There were no differences in recurrence rates for other factors. CONCLUSION: A rigorous evaluation of recurrence for craniopharyngima must consider the extent of resection, as judged by postoperative imaging. Adjuvant radiation therapy or Gamma knife surgery could be the effective treatment modalities.
