PURPOSE: Long-term treatment with inhaled steroids (ICS), especially fluticasone that developed lately, may suppress the hypothalamic-pituitary-adrenal (HPA) axis. This study investigated the relationship between ICS use and HPA axis suppression in asthmatics under ICS treatment for average 4.5 years. METHODS: The medical records of 129 adult asthmatics who received ICS treatment for 6 months or more and underwent a corticotropin stimulation test from January 2005 to August 2013 were retrospectively reviewed. RESULTS: The patients received ICS only (n=87) were found to have an abnormal response to the corticotropin test in as high as 32.2%, and those received ICS in combination with oral steroids (n=42) had a significantly higher prevalence of the response (71.4%, P<0.001). Abnormal responses to corticotropin occurred depending on ICS daily doses (low, n=8, 12.5%; medium, n=19, 36.8%; high, n=102, 49.0%; chi2=4.384, P=0.036). Among the subjects received ICS only, nasal steroid doses (P=0.016) but not ICS doses (P=0.159) were significantly higher in those with abnormal responses than the others. Among all the subjects, oral steroid use (odds ratio [OR], 4.27; 95% confidence interval [CI], 2.35-11.80; P<0.001) and nasal steroid dose (OR, 1.02; 95% CI, 1.00-1.04; P=0.015) were significant risk factors for HPA axis suppression. CONCLUSION: One-third of asthmatics under long-term treatment with ICS showed a suppression of the HPA axis in a dose-dependent manner. Oral or nasal steroid use may be a risk factor for the suppression. However, since our results may have been overestimated due to subject selection bias, further prospective case-control studies are warranted.

Mazabraud syndrome (MS) is a rare and sporadic disorder. It is mainly characterized by fibrous dysplasia (FD) of single or multiple bones and intramuscular myxomas (IM). Data on the prevalence since it was first reported, clinical features, and prognosis are extremely scarce. We report a case of a 59-year-old woman with IM and polyostotic FD. She also had multiple cafe’-au-lait spots suggestive of McCune-Albright syndrome (MAS). On magnetic resonance imaging, there are masses with well-defined heterogeneous enhancement, accompanied by an inner cyst in the vastus lateralis muscle and femur. These radiological results are identical to those of FD. After surgical intervention with excision of intramuscular soft-tissue mass, a diagnosis of IM of MS was confirmed. Given that cafe’-au-lait spots also appeared, the patient was diagnosed with a variant of MS with some of the clinical characteristics of MAS.

Isolated head and neck metastasis of renal cell carcinoma (RCC) is relatively rare and metastasis to the temple area is very rare. Here, we present the case of a 51-year-old man who was diagnosed with RCC 2 years earlier and had a contralateral metastatic temple area lesion. The patient who was diagnosed with renal cell cancer and underwent a nephrectomy 2 years ago was referred to the plastic surgery department for a temple mass on the contralateral side. In the operative field, the mass was located in the temporalis muscle with a red-to-purple protruding shape. Biopsy of the mass revealed a metastatic RCC lesion. Computed tomography imaging showed a lobulated, contoured enhancing lesion. Positron emission tomography/computed tomography imaging showed high-fluorodeoxyglucose uptake in the right temporalis muscle. The patient underwent wide excision of the metastatic RCC including the temporalis muscle at the plastic surgery department. Skeletal muscle metastasis of head and neck lesions is extremely rare in RCC. Isolated contralateral temporalis muscle metastasis in RCC has not been previously reported in the literature. If a patient has a history of malignant cancer, plastic surgeons should always consider metastatic lesions of head and neck tumors. Because of its high metastatic ability and poor prognosis, it is very important to keep this case in mind.

Background:
Frontal sinus fractures are relatively rare. Their surgical management significantly differs depending on whether the posterior wall is invaded and the clinical features vary. A bicoronal incision or endoscopic approach can be used. However, the minimally invasive approach has been attracting attention, leading us to introduce a simple and effective surgical method using multiple-threaded Kirschner wires.
Methods:
All patients had isolated anterior wall fractures without nasofrontal duct impairment. The depth from the skin to the posterior wall was measured using computed tomography to prevent injury. The edge of the bone segment on the skin was marked, a threaded Kirschner wire was inserted into the center of the bone segment, and multiple Kirschner wires were gently reduced simultaneously.
Results:
Surgery was performed on 11 patients. Among them, seven patients required additional support for appropriate fracture reduction. Therefore, a periosteal elevator was used as an adjunct through a small sub-brow incision because the reduction was incomplete with the Kirschner wire alone. The reduction results were confirmed using facial bone computed tomography 1 to 3 days postoperatively. The follow-up period was 3 to 12 months.
Conclusion
The patients had no complications and were satisfied with the surgical results. Here we demonstrated an easy and successful procedure to reduce a pure anterior wall frontal sinus fracture via non-invasive threaded Kirschner wire reduction.

A 51-year-old man was referred for a skin defect with paresthesia and decreased pain in his right ala. He had a history of herpes zoster infection 3 weeks previously. Excisional biopsy and culture showed no evidence of skin malignancy or infection. He was diagnosed with trigeminal trophic syndrome (TTS) after herpes zoster infection. A two-stage folded nasolabial flap was used to reconstruct the defect. The patient was satisfied with the cosmetic outcomes of surgery, and there was no evidence of recurrence during the follow-up. TTS, a rare skin condition that presents with paresthesia, anesthesia, and facial ulceration, occurs after trigeminal nerve injury, which can be caused by herpes zoster infection in rare cases. TTS is an often-persistent condition with a high recurrence rate, causing cosmetic problems. Some surgical methods have been attempted, but our case presents the first use of a folded nasolabial flap to treat TTS. The flap was symmetric, without any nostril collapse. It is also noteworthy that the outcome was excellent with only a skin flap that did not use a bony framework. Herein, we report a rare case of TTS that occurred after herpes zoster infection and was successfully treated with a folded nasolabial flap.

Background:
The reconstruction of large full-thickness alar defects requires complex surgical procedures that are usually performed in two stages, with concomitant disadvantages in terms of patient trauma, surgical risk, and cost. This study presents a functional folded nasolabial island flap (FNIF) that can be used to repair large-sized full-thickness alar defects in a straightforward manner.
Methods:
This retrospective study included seven patients who received a FNIF for a full-thickness alar defect between January 2007 and December 2020. The FNIF is different from the conventional nasolabial flap in that it is folded and twisted to achieve nostril reconstruction with a satisfactory three-dimensional mucosal lining in a single stage. The cosmetic and functional results of FNIF were evaluated by both patients and physicians.
Results:
The age ranged from 51 to 82 years (mean, 65.6 years). The causes of the defects were squamous cell carcinoma, basal cell carcinoma, and trigeminal trophic syndrome. The nostril lining did not collapse, there was no hypertrophic scarring, and air movement through the nostrils on the flap side was normal. Overall, FNIF produced excellent aesthetic and functional outcomes, with minimal patient discomfort. There were no postoperative complications.
Conclusion
Compared with existing reconstruction methods for large full-thickness alar defects, FNIF can easily achieve aesthetic and functional success in a single-stage procedure. It provides satisfactory results for both the patient and the surgeon.

A 46-year-old female presented a mass on her right lower leg where she had a burn injury due to moxibustion 10 years ago. Physical examination revealed a 3 cm sized firm nodule with tenderness. Plain radiograph was performed and it revealed well-defined calcifications. According to the history of moxibustion burn injury and the result of plain radiograph, dystrophic calcinosis cutis caused by burn injury was suspected. The patient underwent excisional biopsy using pre-,intra-, and postoperative ultrasonography (USG). There was no sign of recurrence. Herein, we report a case of a 46-year-old healthy woman who presented with single hard nodule on the right lower leg. Our case is worthwhile in two respects. First, It is first case report of dystrophic calcinosis cutis due to moxibustion burn injury. In east asian culture, moxibustion is a commonly conducted procedure and it often induces burn injury. Second, USG was used pre-, intra-, and post-operatively to assess the shape, location, and depth of the calcinosis cutis and to determine the surgical margin.
