Clinical factors in patients with congenital muscular torticollis treated with surgical resection

BACKGROUND: Congenital muscular torticollis (CMT) is characterized by persistent head tilt toward the affected side. No consensus exists regarding the cause of this disorder. In this study, we analyzed various clinical factors in patients with CMT who were treated with surgical release. This analysis enabled us to identify potential causative factors of CMT and to establish a basis for surgical interventions. METHODS: In total, 584 patients who underwent surgical intervention for CMT from October 2007 to December 2016 were included in this study. Their demographic characteristics, birth-related factors, and clinical features were analyzed. RESULTS: Data from 525 patients were analyzed in this study after exclusion of those with insufficient information. Before birth, 31 patients (5.9%) were diagnosed with oligohydramnios, and 87 (16.6%) had a breech presentation. Seven (1.3%) cases of clavicle fracture and two (0.4%) cases of cephalohematoma were noted at birth. Before surgery, 397 patients (75.6%) underwent physiotherapy and 128 patients (24.4%) did not. The duration of physiotherapy ranged from 1 to 50 months (average, 6 months). CONCLUSIONS: Our study shows that 16.6% of the CMT patients presented in the breech position, which is a much higher rate than that observed in the general population (3%–4%). We hypothesize that being in the breech position as a fetus appears to exert a significant influence on shortening and fibrosis of the sternocleidomastoid muscle.

Solitary mastocytoma presenting at birth

Mastocytosis is a rare disease which occurs in both children and adults, and it can manifest as a solitary or multiple skin lesions. Both can cause cutaneous or systemic symptoms. Because of the heterogeneity of clinical presentation of mastocytosis and its rare prevalence, it can be hard to suspect the mastocytosis at the first time. Most solitary mastocytomas are about 1–5 cm in diameter and have features of brownish-yellow, minimally elevated plaques with a smooth shiny surface. This article presents a case of solitary mastocytoma which occurred in neonate and that we treated through surgical excision. In histopathological examination, it consisted of c-kit-positive mast cells. Although pediatric cutaneous mastocytosis might regress spontaneously, clinicians should keep in mind that it could be associated with systemic mastocytosis which involves hematopoietic system.

Early Transformed Diabetic Foot Ulcer into a Malignancy: A Case Report / 대한족부족관절학회지

This paper presents a case of an early malignant transformation of untreated ulcers in a patient with diabetes. This case shows that Marjolin's ulcer can occur not only after chronic injury, but can also develop in the early stages after the onset. Hence, an early biopsy for diabetic foot ulcers that fail to heal with acute treatment can enable an earlier diagnosis and treatment without amputation, resulting in a better quality of life for the patient.

Primary Merkel cell carcinoma of the earlobe in a young healthy man

Merkel cell carcinoma (MCC) is an uncommon neuroendocrine cutaneous tumor with poor prognosis. It has the high rate of recurrence, mortality, regional nodal involvement, and distant metastases. It is difficult to diagnose MCC because of its non-specific clinical findings. It usually occurs on sun-exposed areas of the skin, mostly at head and neck. There is a difference in the incidence and prognosis according to site in the head and neck. However, there is no consented site-specific diagnosis, treatment or follow-up protocol for MCC at the head and neck. We herein report a case of MCC arising in the right earlobe of an otherwise healthy young man who has been diagnosed early, thereby successfully treated. With our closed follow-up, there was no tumor recurrence or complication at 33 months after diagnosis.

Reduction of Closed Frontal Sinus Fractures through Suprabrow Approach

BACKGROUND: The traditional approach for reduction of frontal sinus fractures is coronal incision. Inherent complications of the coronal approach include long scar, hair loss, and long operation time. We describe a simple approach for the reduction of frontal sinus anterior wall fractures using a suprabrow incision that is commonly used for brow lift. METHODS: From March 2007 to October 2016, the authors identified patients with anterior wall frontal sinus fractures treated by open reduction through a suprabrow incision. Only cases with photographic/radiographic documentation and a minimum follow-up of 6 months were included. The incision line was designed to be at the upper margin of the eyebrow. Medical records and radiographic data were retrospectively reviewed. Surgical outcomes, cosmetic results, and complication were assessed. The patient scale of the patient and observer scar assessment scale was used to assess patient satisfaction for incisional scar at the 6-month follow-up. RESULTS: Thirty-one patients underwent fracture reduction through a suprabrow approach during the study period, with a mean follow-up of 41 months. No patients showed any recurrent displacement, eyebrow asymmetry, or infection during follow-up. Thirteen patients reported their forehead paresthesia postoperatively, and 12 of them had preoperative symptom. One patient complained of incisional scar and underwent scar revision. All patients were satisfied with their eyebrow and forehead contour. CONCLUSION: The suprabrow approach allowed for an accurate reduction of the fractures in the anterior wall frontal sinus by providing direct visualization of the fracture. This transcutaneous approach can effectively restore forehead contour with acceptable postoperative complications and patient satisfaction.

Nodular Fasciitis of the Periorbital Area

Nodular fasciitis is a reactive, non-neoplastic lesion that is most commonly found in the subcutaneous or superficial fascia of the extremities and trunk. Head and neck lesions are relatively uncommon and reports vary from 7% to 15% depending on the authors. Nodular fasciitis grows quickly, and shows a pleomorphic spindle cell pattern with increased mitotic activity. Such factors lead to cases where the lesion is mistaken for a malignancy such as fibrosarcoma and the case may end up with unnecessarily aggressive treatments. The intent of this paper is to report a relatively rare case of nodular fasciitis occurring in the periorbital area and also to highlight the importance of accurate diagnosis and non-aggressive management of this benign lesion.

In Vivo Effects of Adipose-Derived Stem Cells in Inducing Neuronal Regeneration in Sprague-Dawley Rats Undergoing Nerve Defect Bridged with Polycaprolactone Nanotubes

There have been many attempts for regeneration of peripheral nerve injury. In this study, we examined the in vivo effects of non-differentiated and neuronal differentiated adipose-derived stem cells (ADSCs) in inducing the neuronal regeneration in the Sprague-Dawley (SD) rats undergoing nerve defect bridged with the PCL nanotubes. Then, we performed immunohistochemical and histopathologic examinations, as well as the electromyography, in three groups: the control group (14 sciatic nerves transplanted with the PCL nanotube scaffold), the experimental group I (14 sciatic nerves with the non-differentiated ADSCs at a density of 7x105 cells/0.1 mL) and the experimental group II (14 sciatic nerves with the neuronal differentiated ADSCs at 7x105 cells/0.1 mL). Six weeks postoperatively, the degree of the neuronal induction and that of immunoreactivity to nestin, MAP-2 and GFAP was significantly higher in the experimental group I and II as compared with the control group. In addition, the nerve conduction velocity (NCV) was significantly higher in the experimental group I and II as compared with the control group (P=0.021 and P=0.020, respectively). On the other hand, there was no significant difference in the NCV between the two experimental groups (P>0.05). Thus, our results will contribute to treating patients with peripheral nerve defects using PCL nanotubes with ADSCs.

Efficacy and Safety of Porcine Collagen Filler for Nasolabial Fold Correction in Asians: A Prospective Multicenter, 12 Months Follow-up Study

Recently, injectable dermal fillers have become important alternatives to surgical procedures for the correction of facial wrinkles. Bovine collagen is the first approved material for filler injection, and several studies have shown its efficacy. However, the risk of developing an allergic reaction and xenogenic transmission of bovine spongiform encephalopathy remain among its disadvantages. In this randomized, double-blinded, split-face study, we compared the efficacy and safety of a porcine collagen filler (TheraFill(R)) with that of a bovine collagen filler (KOKEN(R)) for nasolabial fold correction. A total of sixty one patients with mild to severe nasolabial fold were randomized to receive TheraFill(R) and KOKEN(R) on contralateral sides of the face. During the 12-month follow-up period, improvement in the Wrinkle-Severity Rating Scale score was slightly higher in TheraFill(R) group than KOKEN(R) group, although the difference was not statistically significant. No serious adverse reactions were observed and both materials were tolerable in most cases. In conclusion, the long-term effect of TheraFill(R) on nasolabial fold correction was comparable to that of KOKEN(R), and it may be a good alternative to bovine collagen filler.

Prevention of Postsurgical Scars: Comparsion of Efficacy and Convenience between Silicone Gel Sheet and Topical Silicone Gel

To date, few studies have compared the effectiveness of topical silicone gels versus that of silicone gel sheets in preventing scars. In this prospective study, we compared the efficacy and the convenience of use of the 2 products. We enrolled 30 patients who had undergone a surgical procedure 2 weeks to 3 months before joining the study. These participants were randomly assigned to 2 treatment arms: one for treatment with a silicone gel sheet, and the other for treatment with a topical silicone gel. Vancouver Scar Scale (VSS) scores were obtained for all patients; in addition, participants completed scoring patient questionnaires 1 and 3 months after treatment onset. Our results reveal not only that no significant difference in efficacy exists between the 2 products but also that topical silicone gels are more convenient to use. While previous studies have advocated for silicone gel sheets as first-line therapies in postoperative scar management, we maintain that similar effects can be expected with topical silicone gel. The authors recommend that, when clinicians have a choice of silicone-based products for scar prevention, they should focus on each patient's scar location, lifestyle, and willingness to undergo scar prevention treatment.

One-Stage Nipple and Breast Reconstruction Following Areola-Sparing Mastectomy

BACKGROUND: Skin-sparing mastectomy with immediate breast reconstruction is increasingly becoming a proven surgical option for early-stage breast cancer patients. Areola-sparing mastectomy (ASM) has also recently become a popular procedure. The purpose of this article is to investigate the reconstructive and aesthetic issues experienced with one-stage nipple and breast reconstruction using ASM. METHODS: Among the patients who underwent mastectomy between March 2008 and March 2010, 5 women with a low probability of nipple-areolar complex malignant involvement underwent ASM and immediate breast reconstruction with simultaneous nipple reconstruction using the modified C-V flap. The cosmetic outcomes of this series were reviewed by plastic surgeons and patient self-assessment and satisfaction were assessed via telephone interview. RESULTS: During the average 11-month follow-up period, there were no cases of cancer recurrence, the aesthetic outcomes were graded as excellent to very good, and all of the patients were satisfied. Two patients developed a gutter-like depression around the reconstructed nipple, and one patient developed skin erosion in a small area of the areola, which healed with conservative dressing. The other complications, such as necrosis of the skin flap or areola, seroma, hematoma, or fat necrosis did not occur. CONCLUSIONS: Since one-stage nipple and breast reconstruction following ASM is an oncologically safe, cost-effective, and aesthetically satisfactory procedure, it is a good surgical option for early breast cancer patients.

A Case of DiGeorge Syndrome with Metopic Synostosis

PURPOSE: We report a patient with DiGeorge syndrome who was later diagnosed as mild metopic synostosis and received anterior 2/3 calvarial remodeling. METHODS: A 16-month-old boy, who underwent palatoplasty for cleft palate at Chungnam National University Hospital when he was 12 months old of age, visited St. Mary's Hospital for known DiGeorge syndrome with craniosynostosis. He had growth retardation and was also diagnosed with hydronephrosis and thymic agenesis. His chromosomal study showed microdeletion of 22q11.2. On physical examination, there were parieto-occipital protrusion and bifrontotemporal narrowing. The facial bone computed tomography showed premature closure of metopic suture, orbital harlequin sign and decreased anterior cranial volume. The interorbital distance was decreased(17mm) and the cephalic index was 93%. RESULTS: After the correction of metopic synostosis by anterior 2/3 calvarial remodeling, the anterior cranial volume expanded with increased interorbital distance and decreased cephalic index. Fever and pancytopenia were noted at 1 month after the operation, and he was diagnosed as hemophagocytic lymphohistiocytosis by bone marrow study. He however, recovered after pediatric treatment. There was no other complication during the 12 month follow up period. CONCLUSION: This case presents with a rare combination of DiGeorge syndrome and metopic synostosis. When a child is diagnosed with DiGeorge syndrome soon after the birth, clinicians should keep in mind the possibility of an accompanying craniosynostosis. Other possible comorbidities should also be evaluated before the correction of craniosynostosis in patients as DiGeorge syndrome. In addition, postoperative management requires a thorough follow up by a multidisciplinary team of plastic surgeons, neurosurgeons, ophthalmologists and pediatricians.
