The nose is a complex three-dimensional structure and represents a major aesthetic focus of the face. As a gold standard for nasal soft tissue reconstruction, the ‘forehead flap’ provides reconstructive surgeons a robust pedicle and large amount of tissue to reconstruct almost any defect. However, during this process, some hair can be unintentionally introduced to the nose. Accordingly, laser hair removal is sometimes needed, but blood circulation and flap survival should be carefully monitored.Despite careful evaluation, a third-degree burn occurred in our patient that required eight weeks to heal. Here, we report on a burn resulting from epilation conducted 2 weeks after forehead flap for nasal reconstruction.

Sebaceous carcinoma (SC) is a rare malignant tumor, with an estimated incidence of approximately 1 to 2 per 1,000,000 per year. Approximately 75% of SCs are reported to occur in eyelids. Most of these tumors are diagnosed at age 40 or over and exhibit a wide variety of patterns in addition to the general appearance previously reported. SC is difficult to diagnose clinically, but can be diagnosed by accompanying biopsy. In cases of SC, additional examinations, such as endoscopy and computed tomography, may be necessary because of its association with Muir-Torre Syndrome. We present the case of a 22-year-old Asian man who complained of a rapidly growing chin tumor. The tumor was treated by surgical resection and adjuvant radiation therapy.

Hidradenitis suppurativa (HS) is a chronic inflammatory condition with an unclear etiopathogenesis that is considered to be a follicular occlusive disease. We present a case of HS that was suspected to have developed as a complication of subdermal excision. A 19-year-old man who had undergone subdermal excision due to osmidrosis presented 7 months after surgery with a persistent painful mass in his left axilla. Despite medical treatment, incision, and drainage, a painful enlarged abscess recurred in the left axilla and was cured completely by deroofing surgery. However, 15 months after subdermal excision, he revisited the hospital because of a painful mass in the right axilla. The patient’s condition met the diagnostic criteria of HS. After several recurrences, a cure was achieved by radical wide excision. Mechanical stress like that associated with subdermal excision is considered to be a possible etiological factor of HS. In addition, pathological changes at the sebofollicular junction allow rupture and leakage of folliculopilosebaceous units upon exposure to mechanical stress, which may result in the aggressive subcutaneous extension of inflammation. We suggest that HS should be considered in patients with a recurrent abscess after subdermal excision, and recommend surgical treatment as a possible option if conservative treatment is clinically ineffective.

BACKGROUND: Because conventional echocardiographic parameters have several limitations, strain echocardiography has often been introduced in clinical practice. However, there are also obstacles in using it in clinical practice. Therefore, we wanted to find the current status of awareness on using strain echocardiography in Korea. METHODS: We conducted a nationwide survey to evaluate current use and awareness of strain echocardiography from the members of the Korean Society of Echocardiography. RESULTS: We gathered total 321 questionnaires from 25 cardiology centers in Korea. All participants were able to perform or interpret echocardiographic examinations. All participating institutions performed strain echocardiography. Most of our study participants (97%) were aware of speckle tracking echocardiography and 185 (58%) performed it for clinical and research purposes. Two-dimensional strain echocardiography was the most commonly used modality and left ventricle (LV) was the most commonly used cardiac chamber (99%) for clinical purposes. Most of the participants (89%) did not think LV strain can replace LV ejection fraction (LVEF) in their clinical practice. The common reasons for not performing routine use of strain echocardiography was diversity of strain measurements and lack of normal reference value. Many participants had a favorable view of the future of strain echocardiography. CONCLUSION: Most of our study participants were aware of strain echocardiography, and all institutions performed strain echocardiography for clinical and research purposes. However, they did not think the LV strain values could replace LVEF. The diversity of strain measurements and lack of normal reference values were common reasons for not using strain echocardiography in clinical practice.

BACKGROUND AND OBJECTIVES: We compared the efficacy and safety of valsartan and rosuvastatin combination therapy with each treatment alone in hypercholesterolemic hypertensive patients. SUBJECTS AND METHODS: Patients who met inclusion criteria were randomized to receive 1 of the following 2-month drug regimens: valsartan 160 mg plus rosuvastatin 20 mg, valsartan 160 mg plus placebo, or rosuvastatin 20 mg plus placebo. The primary efficacy variables were change in sitting diastolic blood pressure (sitDBP) and sitting systolic blood pressure (sitSBP), and percentage change in low-density lipoprotein-cholesterol (LDL-C) in the combination, valsartan, and rosuvastatin groups. Adverse events (AEs) during the study were analyzed. RESULTS: A total of 354 patients were screened and 123 of them were finally randomized. Changes of sitDBP by least squares mean (LSM) were -11.1, -7.2, and -3.6 mm Hg, respectively, and was greater in the combination, as compared to both valsartan (p=0.02) and rosuvastatin (p<0.001). Changes of sitSBP by LSM were -13.2, -10.8, and -4.9 mm Hg, and was greater in the combination, as compared to rosuvastatin (p=0.006) and not valsartan (p=0.42). Percentage changes of LDL-C by LSM were -52, -4, and -47% in each group, and was greater in the combination, as compared to valsartan (p<0.001), similar to rosuvastatin (p=0.16). Most AEs were mild and resolved by the end of the study. CONCLUSION: Combination treatment with valsartan and rosuvastatin exhibited an additive blood pressure-lowering effect with acceptable tolerability, as compared to valsartan monotherapy. Its lipid lowering effect was similar to rosuvatatin monotherapy.

In the previous experiments, we reported that ethanol extract of Gastrodiae Rhizoma, the dried tuber of Gastrodia ElataBlume (Orchidaceae) increased pentobarbital-induced sleeping behaviors. These experiments were undertaken to know whether 4-hydroxybenzaldehyde (4-HBD), is one of the major compounds of Gastrodiae Rhizoma increases pentobarbital-induced sleeping behaviors and changes sleep architectures via activating GABA(A)-ergic systems in rodents. 4-HBD decreased locomotor activity in mice. 4-HBD increased total sleep time, and decreased of sleep onset by pentobarbital (28 mg/kg and 40 mg/kg). 4-HBD showed synergistic effects with muscimol (a GABA(A) receptor agonist), shortening sleep onset and enhancing sleep time on pentobarbital-induced sleeping behaviors. On the other hand, 4-HBD (200 mg/kg, p.o.) itself significantly inhibited the counts of sleep-wake cycles, and prolonged total sleep time and non-rapid eye movement (NREM) in rats. Moreover, 4-HBD increased intracellular Cl- levels in the primary cultured cerebellar cells. The protein levels of glutamic acid decarboxylase (GAD) and GABA(A) receptors subunits were over-expressed by 4-HBD. Consequently, these results demonstrate that 4-HBD increased NREM sleep as well as sleeping behaviors via the activation of GABA(A)-ergic systems in rodents.

BACKGROUND: Spectacle contact allergy is not infrequent. The fine scratches on the spectacle frames which may play a role in the sensitization to the potential allergenic components have not been studied. OBJECTIVE: We sought the relationship between the scratches on the spectacle frames and the allergic contact dermatitis (ACD) in the Republic of Korea. METHODS: A total of 42 Korean patients with ACD at the spectacle contact sites were enrolled. Their spectacle frames were examined with the dimethylglyoxime (DMG) test and analyzed by the scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Patch tests (thin-layer rapid use epicutaneous test [TRUE tests]) were performed to identify the skin allergens. RESULTS: The DMG-positive spectacle frames were identified in 78.5% of the frames. The SEM results showed that there were more scratches on the skin-contacting parts of the spectacle frames than the non-skin-contacting parts of the same frames. In the EDS findings, the mean nickel content (weight, %) of the spectacle frames was 15.7+/-5.5, and the mean chromium content was 20.3+/-3.4 at the skin-contacting parts. In the TRUE tests, nickel sulphate was the most common allergen (31 cases, 73.8%), and potassium dichromate was the second (9 cases, 21.4%). Three patients presented simultaneous positive reactions with nickel sulphate and potassium dichromate. CONCLUSION: Minor visible and non-visible fine scratches on the spectacle frames may present the provocation factors of the ACD. Nickel sulphate was the most common allergen suspected of provoking the spectacle frame-induced ACD, followed by potassium dichromate.
