RESUMO
Cellulite in the proximal lower extremities is a reported concern among many adult females. The unsightly appearance of cellulite leads many affected individuals to seek treatment by trained specialists. The objective of this review is to provide the reader with an update on new and innovative therapies for cellulite including various treatment combinations to maximize therapeutic outcomes, and strategies for minimizing adverse events. The availability of new technologies and the results from recent clinical trials provide additional tools and data to consider when creating treatment plans for cellulite patients. This update to previous treatment recommendations is based on the most recent developments in cellulite management including the personal experiences of the authors with an emphasis on injectable enzymes, acoustic subcision, targeted verifiable subcision, and biostimulators. Formal clinical studies are warranted to compare various treatment modalities and further investigate combination regimens.

Word retrieval is core to language production and relies on complementary processes: the rapid activation of lexical and conceptual representations and word selection, which chooses the correct word among semantically related competitors. Lexical and conceptual activation is measured by semantic priming. In contrast, word selection is indexed by semantic interference and is hampered in semantically homogeneous (HOM) contexts. We examined the spatiotemporal dynamics of these complementary processes in a picture naming task with blocks of semantically heterogeneous (HET) or HOM stimuli. We used electrocorticography data obtained from frontal and temporal cortices, permitting detailed spatiotemporal analysis of word retrieval processes. A semantic interference effect was observed with naming latencies longer in HOM versus HET blocks. Cortical response strength as indexed by high-frequency band (HFB) activity (70-150 Hz) amplitude revealed effects linked to lexical-semantic activation and word selection observed in widespread regions of the cortical mantle. Depending on the subsecond timing and cortical region, HFB indexed semantic interference (i.e., more activity in HOM than HET blocks) or semantic priming effects (i.e., more activity in HET than HOM blocks). These effects overlapped in time and space in the left posterior inferior temporal gyrus and the left prefrontal cortex. The data do not support a modular view of word retrieval in speech production but rather support substantial overlap of lexical-semantic activation and word selection mechanisms in the brain.

Linear immunoglobulin A bullous dermatosis (LABD) is an idiopathic or drug-induced vesiculobullous disease typically managed with dapsone or colchicine. We report a case of LABD successfully treated with rituximab in a patient who was intolerant to first-line therapies and recalcitrant to typical immunosuppressants. The patient was initially started on prednisone and mycophenolate mofetil which resulted in minimal response and disease progression. Improvement was seen after two infusions of rituximab 1000 mg at 2 weeks apart with planned maintenance therapy.
RESUMO
Recent emergence of immune checkpoint inhibitors (ICIs) has revolutionized the treatment of cancers and produced prolonged response by boosting the immune system against tumor cells. The primary target antigens are cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), a downregulator of T-cell activation, and programmed cell death-1 receptor (PD-1), a regulator of T-cell proliferation. This enhanced immune response can induce autoimmune adverse effects in many organs. Although skin toxicities are the most common, sarcoidal inflammation with exclusive cutaneous involvement is a rare occurrence with only 6 cases reported to date. We report 2 cases with unusual features. One patient is a female who was treated for metastatic renal cell carcinoma with combination of ipilimumab (anti-CTLA-4) and nivolumab (anti-PD-1). She developed deep nodules showing sarcoidal dermatitis and panniculitis on histopathologic exam. The second patient is a male with melanoma of eyelid conjunctiva who was treated prophylactically with ipilimumab. He presented with papules/plaques confined to black tattoos, where the biopsy revealed sarcoidal dermatitis. By a comprehensive literature review, we intend to raise awareness about this potential skin side effect in the growing number of patients receiving targeted immunotherapies. It is crucial to have a high index of suspicion and perform timely biopsies to implement appropriate management strategies.
