Facial dimple creation is a simple surgical procedure. Nonetheless, several complications can occur. Actinomycosis is a rare chronic granulomatous infection caused by Actinomyces species. Some conditions that can cause actinomycosis are trauma, oral surgery, and poor dental hygiene. We report a case of actinomycosis that developed on a created facial dimple. A 51-year-old woman presented with a palpable mass on her left cheek that was approximately 1 cm in size. She had undergone facial dimple-creating surgery on both perioral areas at a local clinic 12 years previously. She had not experienced any problems until she was diagnosed with rheumatoid arthritis and diabetes mellitus about 2 years previously, for which she took leflunomide and methotrexate. The mass was completely excised through an intraoral approach. The specimen was grossly described as a gray-yellow cystic mass containing non-absorbable suture material. The filamentous nature of the Actinomyces organisms was observed in dark-stained foci on a histologic examination, confirming the diagnosis of actinomycosis. Indwelling non-absorbable suture materials may increase the risk for opportunistic infections, such as actinomycosis, in immunocompromised patients. Therefore, plastic surgeons should be aware of a patient's general hygiene, immune condition, and medical history when using these materials.

BACKGROUND: Breast reconstruction involves several steps, culminating in the creation of the nipple-areolar complex. Numerous methods of nipple reconstruction have been attempted, and have all proven somewhat successful in providing tissue for projection. In this clinical study, we evaluated a new technique using an acellular dermal matrix (ADM; AlloDerm®) adjunct to a skin flap (C-V flap technique) in nipple reconstruction. METHODS: In 2016, 13 nipple reconstructions were performed using this technique. We designed the C-V flap in the proper position on the breast. After the skin flap was elevated, a 1.5 × 1.5-cm AlloDerm® section was grafted to the inner surface of the elevated C-V flap; the grafted area was then folded into a cylindrical shape. Nipple projection was measured with an electronic caliper at the time of surgery and at 3 weeks and 3 months postoperatively. RESULTS: Immediately postoperatively, nipple projection ranged from 5 to 11 mm (mean, 8.1 mm). The mean maintenance of nipple projection at 3 months postoperatively was 73.14% ± 16.39% (82% and 58% in the breast implant and autologous tissue flap groups, respectively), as compared with the immediate postoperative measurements. CONCLUSIONS: Our results demonstrated a good maintenance rate of ADM retention. Our method is easy to implement and focuses on the maximal retention of ADM to provide long-term projection of the reconstructed nipple.

Background: Implant-based breast reconstruction is a technique frequently used for breast reconstruction. Infection and inflammation are considered to be the most troublesome complications of implant-based breast reconstruction and can lead to capsular contracture or implant failure. To date, however, only a few methods have been proposed to prevent these complications. Therefore, the authors introduce a simple irrigation system using indwelling drain catheters to decrease postoperative inflammation. Methods: Continuous saline irrigation was performed once per day for 3 days immediately after prosthesis-based breast reconstruction. Normal saline (500 mL) was inserted into the implant pocket through a superomedial-oriented drain catheter and drained through an inferolateral-oriented drain catheter using a suction device. Inflammatory indicators, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell count (WBC), and postoperative complications were compared between the non-irrigation and irrigation groups. Results: This study included 37 patients divided into two groups (20 non-irrigation and 17 irrigation). An analysis of inflammatory indicators revealed that the peak CRP level in the irrigation group was significantly lower than that in the non-irrigation group, while no statistically significant differences were found for the other mediators (ESR and WBC). In the immediate postoperative period, continuous irrigation effectively washed out tissue debris and blood clots within the implant pocket, which helped maintain the function of the drain catheter and decrease pro-inflammatory mediators. Conclusions This irrigation method was simple and cost-effective for decreasing inflammation within the breast pocket. Furthermore, it can also be applied to infected breast pockets in combination with antibiotics.

BACKGROUND/AIMS: JX-594 is an oncolytic virus derived from the Wyeth vaccinia strain that causes replication-dependent cytolysis and antitumor immunity. Starting with a cross-examination of clinical-trial samples from advanced hepatocellular carcinoma patients having high levels of aldosterone and virus amplification in JX-594 treatment, we investigated the association between virus amplification and aldosterone in human cancer cell lines. METHODS: Cell proliferation was determined by a cell-counting-kit-based colorimetric assay, and vaccinia virus quantitation was performed by quantitative polymerase chain reaction (qPCR) and a viral plaque assay. Also, the intracellular pH was measured using a pH-sensitive dye. RESULTS: Simultaneous treatment with JX-594 and aldosterone significantly increased viral replication in A2780, PC-3, and HepG2 cell lines, but not in U2OS cell lines. Furthermore, the aldosterone treatment time altered the JX-594 replication according to the cell line. The JX-594 replication peaked after 48 and 24 hours of treatment in PC-3 and HepG2 cells, respectively. qPCR showed that JX-594 entry across the plasma membrane was increased, however, the changes are not significant by the treatment. This was inhibited by treatment with spironolactone (an aldosterone-receptor inhibitor). JX-594 entry was significantly decreased by treatment with EIPA [5-(N-ethyl-N-isopropyl)amiloride; a Na+/H+-exchange inhibitor], but aldosterone significantly restored JX-594 entry even in the presence of EIPA. Intracellular alkalization was observed after aldosterone treatment but was acidified by EIPA treatment. CONCLUSIONS: Aldosterone stimulates JX-594 amplification via increased virus entry by affecting the H+ gradient.

BACKGROUND: In recent years, breast implants have been frequently placed in the subcutaneous pocket, in the so-called prepectoral approach. We report our technique of prepectoral implant-based breast reconstruction (IBR), as well as its surgical and aesthetic outcomes, in comparison with subpectoral IBR. We also discuss relevant considerations and pitfalls in prepectoral IBR and suggest an algorithm for the selection of patients for IBR based on our experiences. METHODS: We performed 79 immediate breast reconstructions with a breast implant and an acellular dermal matrix (ADM) sling, of which 47 were subpectoral IBRs and 32 were prepectoral IBRs. Two-stage IBR was performed in 36 cases (20 subpectoral, 16 prepectoral), and direct-to-implant IBR in 43 cases (27 prepectoral, 16 subpectoral). The ADM sling supplemented the inferolateral side of the breast prosthesis in the subpectoral group and covered the entire anterior surface of the breast prosthesis in the prepectoral group. RESULTS: The postoperative pain score was much lower in the prepectoral group than in the subpectoral group (1.78 vs. 7.17). The incidence of seroma was higher in the prepectoral group (31.3% vs. 6.4%). Other postoperative complications, such as surgical site infection, flap necrosis, implant failure, and wound dehiscence, occurred at similar rates in both groups. Animation deformities developed in 8.5% of patients in the subpectoral group and rippling deformities were more common in the prepectoral group (21.9% vs. 12.8%). CONCLUSIONS The indications for prepectoral IBR include moderately-sized breasts with a thick well-vascularized mastectomy flap and concomitant bilateral breast reconstruction with prophylactic mastectomy.

Background: Numerous studies have investigated risk factors for unfavorable outcomes in prosthetic breast reconstruction, such as obesity, perioperative radiotherapy, and acellular dermal matrix use. However, no reports have explored whether the use of the dominant hand influences complications in breast reconstruction. To address this gap in the literature, analyzed complication rates between the dominant and non-dominant sides after reconstruction. Methods: We retrospectively reviewed the charts of 160 patients (170 breasts) who underwent breast reconstruction from February 2017 to March 2022. We analyzed the complications between beasts on the dominant and non-dominant sides according to the reconstruction method. Results: During prosthetic breast reconstruction, the drainage volume and duration on the dominant side exceeded those on the non-dominant side after reconstruction (duration: 9.79 days on the dominant side vs. 9.12 days on the non-dominant side, P=0.196; volume: 771.1 mL on the dominant side vs. 654.3 mL on the non-dominant side, P=0.027). The incidence of complications such as wound dehiscence, mastectomy flap necrosis, and infection was significantly higher in the dominant hand group (infection: 6 vs. 0, P=0.014; dehiscence: 15 vs. 4, P=0.009; flap necrosis: 13 vs. 4, P=0.024). Conclusions Complications including seroma, infection, and mastectomy skin flap necrosis following prosthetic reconstruction were common in breasts on the dominant-hand side. Therefore, meticulous management and restriction of shoulder movement can aid in preventing seroma-related complications in prosthetic breast reconstruction, especially on the side of the dominant hand.
