RESUMO
According to current predictions, one-fifth of all Americans will develop skin cancer during their lifetime. Cutaneous squamous cell carcinoma (cSCC) most commonly occurs in the head and neck region, which is the area of the body with the highest level of sun exposure. High-risk head and neck cSCC (HNcSCC) is a broad category with numerous high-risk factors that are associated with unfavorable results. In cSCC staging systems, clinical and tumor traits that are likely to result in poor outcomes are identified. Metastasis occurs in ~2.5% of patients with cSCC, most often in the local lymph nodes, and there is some indication that lymph node metastasis has a distinct pattern based on the tumor site. Current findings on tumor molecular targets have suggested the use of systemic treatments, particularly immunotherapy (such as cemiplimab, pembrolizumab and nivolumab), over radiotherapy or chemotherapy for this type of metastasis. However, when used simultaneously with immunotherapy, radiotherapy may be beneficial in the treatment of metastatic HNcSCC by improving the efficacy of immunotherapy. The present review aims to assess the existing literature on metastatic HNcSCC pathways and treatment options, in order to define current and future directions. Notably, there is an urgent need to identify patients who may benefit from local or systemic cancer treatments. The treatment of lymph node metastasis presents a therapeutic challenge and requires comprehensive management.
RESUMO
To improve the outcome and quality of life for patients with head and neck carcinoma, an increasing amount of research has been performed on the particularities of this type of cancer and its treatment methods. Starting from clinical aspects, including histology and imaging features, up-to-date studies from different parts of the world have determined new data leading to a better understanding of the mechanisms behind the disease and proposed new treatment protocols. The head and neck areas are predisposed to almost all skin neoplasms, most commonly those related to ultraviolet exposure. Squamous cell carcinoma and basal cell carcinoma account for almost 90% of non-melanoma skin cancers in this region; therefore, reviewing the literature on cutaneous carcinomas of the head and neck area and sharing particular aspects of their physiopathology are beneficial for a great number of patients.
RESUMO
Serous otitis media (SOM) occurs in children and constitutes one of the most significant causes of hearing loss in young age, posing as an important risk factor for long-term hearing loss. SOM is underdiagnosed, most frequently in infants, or the appointment to the ENT doctor is delayed due to non-acute symptomatology. The aim of the present study was to assess 285 patients with SOM diagnosed within a two-year span. The etiology and pathology of hearing loss in patients with different age groups were examined. The importance of a clinical examination and tympanometry was emphasized as absolutely necessary for a correct diagnosis. Treatment targeted Eustachian Tube permeabilization for satisfactory long-term middle ear aeration. Nasal drops with vasoconstrictor drugs (phenylephrine) and disinfectant (colloidal silver 1%) were commonly used, but some patients also benefitted from dexamethasone intratympanic injection. Patients were evaluated at the end of the treatment and follow-up occurred at one month, one year and three years later.
RESUMO
BACKGROUND: Efficient postoperative pain management, which is aimed at decreasing the risk of complications and drug-induced side effects, without affecting the quality of analgesia, is part of today's concept of enhanced recovery after surgery, that is, fast-track surgery. STUDY QUESTION: The objective of this study was to determine whether effective management of acute postoperative pain was possible without opioids, while avoiding complications, drug-induced side effects, and suboptimal treatment. Introduction of metamizole, which has regained popularity, into a multimodal analgesia regimen was used, as opioids are not routinely administered. STUDY DESIGN: The study was prospective, observational, unrandomized, and without the control group. MEASURES AND OUTCOMES: This study was performed in a pediatric hospital with 300 beds and an average of 1700 annual surgical interventions. The study group comprised 378 patients aged 1-17 years, undergoing lower abdominal or limb surgery between June 2016 and June 2017. Children underwent subarachnoid anesthesia combined with intravenous sedation and received not routinely but on demand postoperative opioid analgesia. The pain was self-assessed by the pediatric patient or was assessed by the nurse using pain scores. RESULTS: Metamizole proved to be safe, efficient, and very well tolerated by children. Multimodal analgesia using acetaminophen, nonsteroidal anti-inflammatory drug with metamizole for the treatment of moderate to severe pain in children undergoing surgery, required a single opioid dose in 292 patients (77.24%) of the 378 in this study. CONCLUSIONS: In pediatric patients undergoing surgery, subarachnoid anesthesia combined with intravenous sedation, multimodal analgesia that includes metamizole, and nonpharmacological complementary therapies in pain management enable avoidance or reduction of opioids to a single dose, without undertreatment. There is also a minimum of anesthesia, accelerated children's recovery and a rapid return to presurgical levels of function.
