Femoral artery pseudoaneurysm, a very uncommon disease, is usually reported trauma, iatrogenic vascular intervention, and nail fixation in the treatment of fracture. The femoral artery is a major vessel for blood supply to the lower extremities. If the femoral artery is injured, the patient will experience cardiovascular collapse and hypovolemic shock due to massive hemorrhage. We report on the case of a 49-year-old male patient who had been diagnosed with systemic lupus erythematosus (SLE), who was admitted to our hospital with progressive swelling of the right thigh without any trauma history. A computed tomographic scan with arterial enhancement showed a large pseudoaneurysm of the right femoral artery, which was then treated successfully with great saphenous vein graft surgery.

PURPOSE: The aim of the present study was to determine the effects of mitomycin C (MMC) on eyelash regrowth in rats. METHODS: Ten rats were subjected to bilateral eyelid epilation. One drop of 0.04% MMC solution and one drop of normal saline was then administered to the right and left eyelid, respectively. Three months post-epliation, the number of regrown eyelashes was counted, and a section of tissue from each eyelid was examined under light- and electron microscopies. RESULTS: The number of regrown long eyelashes was 1.0 +/- 0.81 on the right, and 12.5 +/- 1.08 on the left. The rate of regrowth was 7.35 +/- 5.55% on the right and 98.45 +/- 3.27% on the left. Histological examination revealed no significant differences between the right and left eyelids, except for the absence of any hair shafts in the follicles on the right. However, electron microscopy revealed mitochondrial damage in the follicles of the right eyelid. These changes were not observed in tissue from the left eyelid. CONCLUSIONS: The application of 0.04% MMC inhibited the regrowth of normal eyelashes in rats following simple epilation. These results suggest that MMC may be a novel therapy for replacing invasive surgery in trichiasis with no malpositioning.

PURPOSE: To report a case of malignant fibrous histiocytoma of the lateral canthal area that was diagnosed clinically as a benign epidermal inclusion cyst. CASE SUMMARY: A 49 year-old man presented with a cutaneous mass involving the lateral canthal area. A 0.7-cm cystic lesion was freely movable and non-inflamed. After excisional biopsy, the results of immunohistochemical staining led to a final diagnosis of low-grade malignant fibrous histiocytoma. The specimen from excisional biopsy had margins positive for malignancy; the patient underwent a second procedure for complete resection, and that specimen had tumor-free margins. CONCLUSIONS: Fibrous histiocytoma is a rare disease but may occur in the eyelid. Therefore, when an eyelid tumor progresses rapidly, malignant fibrous histiocytoma should be considered as a diagnosis.

PURPOSE: To report a case of chronic dacryocystitis caused by Achromobacter xylosoxidans. CASE SUMMARY: A 73-year-old female was referred to our clinic for management of chronic dacryosyctitis from which she did not to recover despite empirical therapy. A. xylosoxidans was isolated from purulent discharge. Based on the results of susceptibility testing, therapy was changed to fortified ceftazidime eye-drop 6 times a day and intravenous tazocin 4.5 g/20 ml (piperacillin 2 g/tazobactam 0.25 g) 3 times a day. All symptoms were resolved after treatment with sensitive antibiotics and external dacryocystorhinostomy. CONCLUSIONS: To our knowledge, this is the first report of A. xylosoxidans dacryocystitis. A. xylosoxidans are rare but potential pathogens which cause dacryocystitis. The cultures and sensitivity test were collected and processed to detect the presence of unusual pathogens in a case with persistent infection despite conventional treatment.

PURPOSE:
This study attempts to evaluate the skeletal maturation patterns of the triradiate cartilage (TRC) and the posterior acetabular wall (PA), which can be easily assessed on body computerized tomography (CT). It also examines the effect of gender and age on ossification of both TRC and PA.
MATERIALS AND METHODS:
This retrospective study included a total of 1324 CT scans for children between the ages of 6 and 16 years. Depending on the extent of ossification in each right or left aspect, determined by the consensus of two observers, the TRC and PA scans were categorized into Grades 4 and 3, respectively.
RESULTS:
The TRC for boys began to ossify at age 10 and closed completely at 14, while the PA for boys started ossification at age 11 and entirely fused at 13. The ages of ossification center appearance and complete fusion in both TRC and PA for girls were exactly two years earlier than boys. The TRC fused within one year after the closure of the PA.
CONCLUSION
The appearance and closure of the TRC and PA ossification centers show predictable patterns of development, appearance and merger earlier in females than in males. The suggestion is that development and morphogenesis of both TRC and PA ossification centers can be adequately assessed by using 3-dimensional body CT.

Purpose:
To investigate the efficacy and safety of radiofrequency ablation (RFA) for papillary thyroid microcarcinoma (PTMC) after > 10 years of follow-up.
Materials and Methods:
This study included five patients who underwent RFA to treat PTMCs (five lesions, mean diameter 0.5 cm, range 0.4–0.7 cm) between November 2006 and December 2009. The inclusion criteria were histopathologically confirmed PTMCs, a single PTMC lesion without extrathyroidal extension, no metastasis, and ineligibility or refusal to undergo surgery. RFA was performed by a single radiologist using a radiofrequency generator and an internally cooled electrode. We retrospectively analyzed the procedure-induced complications, serial changes in ablated tumors, recurrence, and local as well as lymph node metastasis based on data obtained from medical records and radiological images.
Results:
The mean follow-up period was 130.6 months (range 121–159 months). Three patients underwent a single RFA session, and two patients underwent two RFA sessions. We observed no procedure-induced complications. Three tumors completely disappeared after ablation, and ablation of the other two tumors resulted in the formation of a small scar that showed long-term stability (mean duration 16.8 months, range 12–27 months). At the last follow-up, no patient showed recurrence or lymph node metastasis, and serum thyroglobulin levels were within normal limits in all patients.
Conclusion
RFA may be effective and safe to treat low-risk PTMC in patients who refuse or are ineligible for surgery.

Anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is a rare congenital cardiovascular anomaly. The mortality rate among infants and children without operation has been eighty to ninety-five percents and few patients survive till teen-age or adulthood. This anomaly was detected during elective coronary angiogram in a 32 year-old female patient with atypical chest pain. Reversible ischemia was demonstrated on myocardial 201Tl-SPECT. Coronary angiogram revealed anomalous origin of left coronary artery from pulmonary artery.

OBJECTIVES: The purpose of this study was to investigate the manner by which social anxiety symptoms, self-esteem, and depression influence suicidal ideation in adolescents. METHODS: This study involved 1320 middle school students. All participants completed several self-assessment questionnaires. Correlations among variables were assessed, and multiple regression analysis was performed to evaluate the relationships between variables and suicidal ideation. Finally, a structural equation model was used to determine the pathways by which the tested variables can influence suicidal ideation. RESULTS: Symptoms of social anxiety were positively correlated with depression and suicidal ideation, but were negatively correlated with self-esteem. Additionally, multiple regression analysis revealed that social anxiety symptoms, depression, and self-esteem were significantly related to suicidal ideation. The influence of social anxiety symptoms on suicidal ideation was associated with an increase in depression, whereas self-esteem acted as an intermediary between social anxiety symptoms and depression. CONCLUSION: The results of the present study demonstrate that social anxiety symptoms can directly increase depression and lower self-esteem, which in turn can increase the risk of suicidal ideation. Thus, it may be possible to prevent depression and ultimately lower the risk of suicide in adolescents by pursuing programs designed for the early detection of social anxiety symptoms and by using intervention programs that improve self-esteem.
