Combined with the authors' experience, a new classification system and management of hypersensitivity reactions to HA fillers is proposed of early (up to a week), intermediate (a week to a month), and late (over a month) hypersensitivity reactions. CONCLUSION The classification system proposed provides objective measurements and management options that can be helpful for physicians to navigate these hypersensitivity reactions and design treatment protocols that provide the best clinical outcomes for their patients.BACKGROUND The intradermal technique to inject botulinum toxin is a popular procedure in upper facial rejuvenation to minimize side effects, such as brow ptosis, and can sometimes result in a lifting effect. OBJECTIVE The present study investigated differences in effects according to injection modality. METHODS AND MATERIALS Fifteen women received intradermal injections of botulinum toxin (total dose, 8U) into the forehead, and 14 women received intramuscular injections. RESULTS The maximal antiwrinkle effect was recorded at Week 2, and the duration of the effect was the same in both groups. The brow position was lowered at Weeks 2 and 4 in the intramuscular injection group and was preserved in the intradermal injection group throughout the follow-up period. The amount of maximal voluntary eyebrow movement was decreased at Weeks 2 and 4 and recovered at Week 16 in both groups. The change in the electromyographic amplitude of the frontalis muscle was prolonged until Week 16 in both groups. Subjective satisfaction with wrinkles was similar in both groups. However, the intradermal injection was more painful. CONCLUSION Intradermal injection of botulinum toxin is a safe and effective method to improve forehead rhytides.BACKGROUND Diluted/hyperdiluted calcium hydroxylapatite (CaHA) represents an emerging biostimulatory treatment. However, limited data concerning the effects of this agent on the face have been provided so far. OBJECTIVE To investigate the efficacy and safety of hyperdiluted CaHA 12 treatment for mid and lower face rejuvenation. PATIENTS AND METHODS A retrospective study of 40 patients seeking skin rejuvenation for mid and lower face, treated with hyperdiluted CaHA 12 technique at baseline (T0), was performed. Patients were classified according to validated scales of aging in the mid to lower face at T0 and efficacy was established with scales calculated again at 4-month post-treatment (T1). In addition, efficacy was assessed by blinded evaluation of T0/T1 clinical pictures, non-invasive skin imaging and patient satisfaction. Safety was assessed through pain scale and minor/major adverse events. RESULTS Hyperdiluted CaHA 12 successfully decreased aging severity scores of the mid and lower face. Variations of collagen morphology and increased vessel density at T1 were observed with noninvasive skin imaging. Most patients were very satisfied. Mean pain score was low and only minor adverse events were reported. CONCLUSION Hyperdiluted CaHA 12 technique seems to be effective and safe for mid and lower face skin rejuvenation.BACKGROUND Keratinocyte cancer (KC) patients benefit from early diagnosis. We describe here the anatomy of head/neck KCs to help guide screening efforts. OBJECTIVE To examine lesion frequency and anatomic distribution of head and neck KC. METHODS This retrospective cohort study of 4,770 consecutive pathology reports, 1998 to 2015, analyzes 5,463 head and neck KCs (3,664 basal cell carcinoma [BCC], 1,259 squamous cell carcinoma [SCC], and 540 SCC in situ) from 3,581 patients. RESULTS Basal cell carcinoma relative tumor density (RTD) was highest on the nose; SCC RTD was highest on the cheek. Basal cell carcinoma-to-SCC ratio was highest on eyelid and lowest on scalp. Temple, ear, and neck SCC predominated in men; nose and cheek SCC in women. Scalp, temple, and ear BCC showed male predominance, while cheek, nose, and chin predominated in women. Left-sided ear SCC in situ and BCC were more common than right-sided ear lesions. CONCLUSION This study demonstrates gender- and laterality-specific differences that comport with patterns of solar exposure.The American Society of Clinical Oncology and the College of American Pathologists recommend that human epidermal growth factor receptor 2 (HER2)/neu status be determined for all invasive breast cancers. Although the most commonly used modalities to determine HER2/neu status, immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), generally give concordant results, a small but consistent discordance rate between them has been demonstrated in prior studies. Most institutions in the United States use a "reflex testing strategy" for determining HER2/neu status. selleck compound In a reflex testing strategy, cancers are screened with IHC, and FISH is reflexively performed only if the IHC results are classified as equivocal. Other institutions perform both tests on all cancers to maximize diagnostic accuracy (dual testing strategy). The cost-effectiveness of dual testing and reflex testing strategies are comparatively assessed herein. A decision analysis model was established comparing these 2 testing strategies.classified as HER2/neu-amplified by FISH. Overall, a reflex testing strategy was found to be less costly than a dual testing strategy ($44,470.99 vs. $45,908.86, respectively), but was also less effective (10.28 vs. 10.30 QALYs). The incremental cost-effectiveness ratio was $70,051.55/QALY. In conclusion, in this single institutional cohort of breast cancers, a dual testing strategy to determine HER2/neu status was found to be more cost-effective than a reflex testing strategy.Liposarcoma is the most common soft tissue sarcoma in adults; however, accurate diagnosis often depends on the use of ancillary molecular testing which can be time consuming and expensive. Myxoid/round cell liposarcoma may be a diagnostic challenge due to the morphologic similarities with other nonadipocytic sarcomas with round cell morphology. Immunohistochemistry may be a helpful adjunct to appropriately triage cases for molecular testing. Perilipin 1 (PLIN1) and perilipin 2 (adipophilin) (PLIN2) are intracellular proteins involved in lipid droplet formation, which we hypothesized may be useful as immunohistochemical markers for liposarcoma. Using archival tumor tissue, we assessed pattern of PLIN1 and PLIN2 expression in 46 adipocytic tumors and 36 nonadipocytic sarcomas. PLIN1 was expressed in 88% of liposarcomas, including 100% of myxoid/round cell liposarcomas, and did not have any expression in nonadipocytic sarcomas. PLIN1 was not expressed in dedifferentiated liposarcoma. Although PLIN2 demonstrates increased sensitivity for liposarcoma, including expression in dedifferentiated liposarcoma, it is not specific for adipocytic differentiation and is expressed in other nonadipocytic sarcomas.
