De-epithelialization is a technique that thins out the epidermis layer of the skin to resurface defects in a cavity or to implant a flap pedicle subcutaneously, preserving the subdermal plexus to support the vascularity of the flap. However, in reduction mammoplasty, de-epithelialization of the pedicle is a time-consuming and tedious step. Although various methods have been proposed to facilitate the completion of this step, a standard has not been established. We used a digital automatic injector that could inject a mixture of lidocaine and epinephrine at a constant, adjustable rate without any special effort. With this method, we could inject local anesthetic into the junction of the epidermis and dermis accurately, which saved time by making dissection easier (hydrodis-section) and decreased bleeding during de-epithelialization. Furthermore, we could use less of the lidocaine and epinephrine mixture, thereby reducing its potential side effects.

Background: The pain caused by local anesthetic injection can lead to patient anxiety prior to surgery, potentially necessitating sedation or general anesthesia during the excision procedure. In this study, we aim to compare the pain relief efficacy and safety of using a digital automatic anesthetic injector for local anesthesia. Methods: Thirty-three patients undergoing excision of a benign soft tissue tumor under local anesthesia were prospectively enrolled from September 2021 to February 2022. A single-blind, randomized controlled study was conducted. Patients were divided into two groups by randomization: the experimental group with digital automatic anesthetic injector method (I-JECT group) and the control group with conventional injection method. Before surgery, the Amsterdam preoperative anxiety information scale was used to measure the patients’ anxiety. After local anesthetic was administered, the Numeric Pain Rating Scale was used to measure the pain. The amount of anesthetic used was divided by the surface area of the lesion was recorded. Results: Seventeen were assigned to the conventional group and 16 to the I-JECT group. The mean Numeric Pain Rating Scale was 1.75 in the I-JECT group and 3.82 in conventional group. The injection pain was lower in the I-JECT group (p< 0.01). The mean Amsterdam preoperative anxiety information scale was 11.00 in the I-JECT group and 9.65 in conventional group. Patient’s anxiety did not correlate to injection pain regardless of the method of injection (p= 0.47). The amount of local anesthetic used per 1 cm 2 of tumor surface area was 0.74 mL/cm2 in the I-JECT group and 2.31 mL/cm2 in the conventional group. The normalization amount of local anesthetic was less in the I-JECT group (p< 0.01). There was no difference in the incidence of complications. Conclusion The use of a digital automatic anesthetic injector has shown to reduce pain and the amount of local anesthetics without complication.

BACKGROUND/AIMS: Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat. Given the benign nature of the condition and the association of gastroesophageal reflux disease, empirical therapy with proton pump inhibitor seems reasonable for patients with typical globus. The aim of this study was to investigate the clinical predictors for symptom response to short-term proton pump inhibitor treatment in patients with globus symptom. METHODS: Fifty-four patients with globus symptom were enrolled prospectively. All patients were treated with pantoprazole 40 mg daily for 4 weeks. Treatment response was defined as a > 50% reduction in symptom scores between symptom assessments. Univariate and multivariate logistic regression analysis between responders and non-responders was performed to identify variables predicting response to pantoprazole treatment. RESULTS: Of the 54 consecutive patients considered, 13 were excluded on the basis of exclusion criteria and/or refusal to participate in the study. Finally, 41 patients were included in this study. After 4-week pantoprazole treatment, 22 patients (53.7%) were classified as responders. On multivariate analysis, the presence of reflux symptom was associated with a higher response rate to 4-week pantoprazole treatment (OR, 68.56; P = 0.043), and long symptom duration (> or = 3 months) were associated with a lower response rate to pantoprazole treatment (OR, 0.03; P = 0.034). CONCLUSIONS: Presence of reflux symptom and short symptom duration were independent predictors of responsiveness to 4-week pantoprazole treatment in patients with globus.

Background: Botulinum toxin is a neurotoxic substance with a wide range of uses, from the treatment of musculoskeletal spasms to antiaging regimens by improving wrinkles. Split-face studies in which drugs are injected in the right and left sides of the faces have been actively conducted in botulinum toxin studies. In this study, we aimed to investigate the reliability of a split-face study for determining the effectiveness of botulinum toxin based on eyebrow height and movement, and electromyography results. Methods: Thirty-one women aged 35 to 55 years were included in the study. Eyebrow height was measured as the distance from the eyebrows to the upper eyelid margin on the primary gaze, and eyebrow movement was measured as the distance when the forehead was wrinkled for 5 seconds. A noninvasive method was used for electromyography of the frontalis muscles. Results: No statistically significant differences in right and left eyebrow heights and movements, and electromyography findings (p= 0.256, p= 1.000, and p= 0.978, respectively) were found. Pearson correlation analysis showed that electromyography muscle activity is positively associated with eyebrow movement, respectively (p< 0.001). Conclusion We advocate the reliability of split-face study and the usefulness of electromyography of frontalis muscle in forehead rejuvenation research.

BACKGROUND/AIMS: Autologous stem cell transplantation (ASCT) has become the treatment of choice for patients with multiple myeloma (MM). Studies have shown that maintenance treatment with interferon-alpha is associated with improved survival rates following ASCT. However, despite these recent advances in regimes, relapses are inevitable; thus, the prediction of relapse following ASCT requires assessment. METHODS: We retrospectively analyzed 39 patients who received ASCT between 2003 and 2008. All patients received chemotherapy with vincristine, adriamycin, and dexamethasone (VAD), and ASCT was performed following high-dose melphalan conditioning therapy. We evaluated the influence of the post-transplant day +14 (D+14) bone marrow plasma cell percent (BMPCp) (> or = 2 vs. < 2%), international scoring system (ISS) stage (II vs. III), response after 3 cycles of VAD therapy (complete response [CR] vs. non-CR), deletion of chromosome 13q (del[13q]) (presence of the abnormality vs. absence), and BMPCp at diagnosis (> or = 50 vs. < 50%) on progression-free survival (PFS) and overall survival (OS). RESULTS: During the median follow-up of 28.0 months, the median PFS and OS were 29.1 and 42.1 months, respectively. By univariate analysis, ISS stage III at diagnosis, BMPCp > or = 50% at diagnosis, CR after 3 cycles of VAD therapy, del (13q) by fluorescence in situ hybridization, and BMPCp > or = 2% at post-transplant D+14 were correlated with PFS and OS. A multivariate analysis revealed that a post-transplant D+14 BMPCp > or = 2% (PFS, hazard ratio [HR] = 4.426, p = 0.008; OS, HR = 3.545, p = 0.038) and CR after 3 cycles of VAD therapy (PFS, HR = 0.072, p = 0.014; OS, HR = 0.055, p = 0.015) were independent prognostic parameters. CONCLUSIONS: Post-transplant D+14 BMPCp is a useful parameter for predicting the outcome for patients with MM receiving ASCT.

BACKGROUND/AIMS: There is an increased risk of tuberculosis (TB) with impaired cellular immunity and extrapulmonary TB is more common in patients with chronic kidney disease. We explored the clinical features and treatment outcomes of extrapulmonary TB according to renal function. METHODS: This retrospective study reviewed the medical records of patients diagnosed with extrapulmonary TB between January 2003 and December 2007. We classified the patients into two groups using the glomerular filtration rate (eGFR), estimated using the Modification of Diet in Renal Disease (MDRD) formula cut-off of 60 mL/min/1.73 m2 and evaluated their clinical features, treatment outcome and mortality (Group I vs. Group II, > or = 60 mL/min/1.73 m2). RESULTS: The mean eGFR of Groups I (n=30) and II (n=312) was 34+/-19 and 102+/-26 mL/min/1.73 m2, respectively. The pleura was the most frequent site of TB in both groups (Group I, 30.0% vs. Group II, 28.2%; p=0.379). There was no treatment failure or recurrence in either group. The mortality was higher in Group I (22.2% vs. 2.8%; p<0.01). In a multivariate analysis, eGFR<60 mL/min/1.73 m2 was an independent risk factor for mortality (HR=11.51, CI 2.512-52.741; p=0.002). CONCLUSIONS: Mortality related to extrapulmonary TB was higher in patients with impaired kidney function and kidney function was an independent predictor. However, there was no difference in treatment failure and recurrence according to renal function.
