RESUMEN
BACKGROUND: Postoperative analgesia in breast surgery is difficult due to the extensive nature of the surgery and the complex innervation of the breast; general anesthesia can be associated with regional anesthesia techniques to control intra- and post-postoperative pain. This randomized comparative study aimed to compare the efficacy of the erector spinae plane block and the thoracic paravertebral block in radical mastectomy procedures with or without axillary emptying. METHODS: This prospective randomized comparative study included 82 adult females who were randomly divided into two groups using a computer-generated random number. Both groups, Thoracic Paraverterbal block group and Erector Spinae Plane Block group (41 patients each), received general anesthesia associated with a multilevel single-shot thoracic paravertebral block and a multilevel single-shot erector spinae plane block, respectively. Postoperative pain intensity (expressed as Numeric Rating Scale), patients who needed rescue analgesic, intra- and post-operative opioid consumption, post-operative nausea and vomiting, length of stay, adverse events, chronic pain at 6 months, and the patient's satisfaction were recorded. RESULTS: At 2 h (p < 0.001) and 6 h (p = 0.012) the Numeric Rating Scale was significantly lower in Thoracic Paraverterbal block group. The Numeric Rating Scale at 12, 24, and 36 postoperative hours did not show significant differences. There were no significant differences also in the number of patients requiring rescue doses of NSAIDs, in intra- and post-operative opioid consumption, in post-operative nausea and vomiting episodes and in the length of stay. No failures or complications occurred in the execution of techniques and none of the patients reported any chronic pain at six months from the surgery. CONCLUSIONS: Both thoracic paravertebral block and erector spinae plane block can be effectively used in controlling post-mastectomy pain with no significant differences between the two blocks. TRIAL REGISTRATION: The study was prospectively registered on Clinicaltrials.gov (trial identifier NCT04457115) (first registration 27/04/2020).

BACKGROUND: In last years, many attempts were made to recognize chronic rhinosinusitis with nasal polyps (CRSwNP) phenotypes focusing on identifying relevant key pathogenic molecules. Polyps recurrence rate ranges from 4% to 60%, so it's clear that not all clinical and immunologic factors associated with recurrence are known. OBJECTIVE: We investigate the inflammatory profile in patients with long term recurrent and non-recurrent CRSwNPs and if a specific profile is associated with recurrence, comparing eosinophilic, neutrophilic and lymphocytic infiltration, as well as IL-5 and IL-8 expression to long term recurrence rate. METHODS: This prospective study included 44 adult patients with CRSwNP treated with endoscopic sinus surgery between 2008 and 2010. Long term follow-up data (8-10â¯years) indicated that among 44 patients, 18 (40.1%) experienced long term recurrence of nasal polyposis needing maximal medical treatment or revision surgery. We realized two groups: one with patients who didn't present long term recurrence (26 patients) and another with patients who presented long term recurrence (18 patients) and in both groups eosinophilic, neutrophilic and lymphocytic infiltration and IL-5 and IL-8 expression were measured. RESULTS: The parameters that reached statistical significance (pâ¯<â¯0.05) comparing the two groups were eosinophilic infiltration and IL-5 expression, whereas neutrophilic and lymphocytic infiltration, as IL-8 expression didn't show any significant difference. Asthma and aspirin intolerance seemed significantly more frequent in patients with recurrence, while allergy presented not statistically significant difference between two groups. CONCLUSIONS: We can conclude that high eosinophilic infiltration and high IL-5 expression in CRSwNP correlate with higher rate of long term recurrence, while neutrophilic and lymphocytic infiltration, and IL-8 expression don't correlate with it. These findings provide the opportunity to improve our ability to predict the prognosis of surgical intervention, although it is still needed to explore the optimal predictor of outcome in CRSwNP.

Radiofrequency volumetric tissue reduction is a minimally invasive technique in the treatment of turbinate hypertrophy and is generally performed under local anesthesia. However, perioperative discomfort and pain are common side effects and studies concerning the technique of choice to anesthetize the nasal mucosa in this procedure are lacking. The aim of this prospective controlled trial is to assess the effectiveness of EMLA(®) cream as a topical anesthetic for radiofrequency volumetric tissue reduction of inferior turbinates comparing its effect with that obtained using a traditional anesthetic technique. 200 consecutive patients undergoing volumetric tissue reduction with topical anesthesia were enrolled. Patients were divided into two groups: Group A included 100 patients treated by placing cotton pledgets soaked with lidocaine 10% in the inferior meatus followed by the injection of 2% lidocaine into the head of the inferior turbinate; Group B included 100 patients treated with EMLA(®) cream. Patients were evaluated before and after surgery using rhinomanometry for obstructive symptoms. Four VAS about pain, troublesome swallowing, choking sensation and intraoperative anxiety were submitted to each patient immediately after surgery and after 2 months to assess various aspects of perioperative discomfort. A significant increase of nasal airflow was observed without differences between the two groups. Subjective evaluation regarding perioperative discomfort showed significant differences between Groups A and B immediately after surgery although it was less pronounced 2 months later. The results of this study suggest that EMLA(®) cream is an efficient tool in obtaining an adequate anesthetic effect in this procedure.

Background: Pheochromocytomas and paragangliomas (PPGL) are neuroendocrine tumors that originate from adrenal medulla or extra-adrenal chromaffin cells, respectively. They produce an excess of catecholamines and their metabolites. Abnormal levels of these biomolecules have been also found in pediatric patients with neuroblastoma (NB). Due to the diurnal fluctuation, the laboratory practice recommends the determination of biogenic amines in acidified 24-h urine samples. However, the collection and acidification of specimens cannot be performed easily, especially for children. Spot urines represent an attractive alternative for the detection of catecholamines and corresponding metabolites. Methods: In our study, we enrolled 50 patients with symptoms related to PPGL and we determined the concentration values for both spot and 24-h urine samples using high-performance liquid chromatography tandem mass spectrometry (HPLC/MS-MS). Since day variations of the urinary concentration are due to fluctuations in renal excretion rather than in production, we normalized the concentration of biogenic amines in spot urine and in 24-h urine collection to urinary creatinine concentration. A correlation study between the normalized levels of biogenic amines was performed using a linear regression analysis model and Pearson's correlation coefficients. Results: We obtained a good correlation of values which suggests an interchangeability of the 24-h and random urine samples. Only for epinephrine a weak correlation was determined. Conclusions: Our findings suggest that the sample collection as single spot urine may replace 24-h collection for the detection of urinary biogenic amines by HPLC/MS-MS.
RESUMEN
BACKGROUND: Despite advances and improvements in the management of surgical patients, emergency and trauma surgery is associated with high morbidity and mortality. This may be due in part to delays in definitive surgical management in the operating room (OR). There is a lack of studies focused on OR prioritization and resource allocation in emergency surgery. The Operating Room management for emergency Surgical Activity (ORSA) study was conceived to assess the management of operating theatres and resources from a global perspective among expert international acute care surgeons. METHOD: The ORSA study was conceived as an international web survey. The questionnaire was composed of 23 multiple-choice and open questions. Data were collected over 3 months. Participation in the survey was voluntary and anonymous. RESULTS: One hundred forty-seven emergency and acute care surgeons answered the questionnaire; the response rate was 58.8%. The majority of the participants come from Europe. One hundred nineteen surgeons (81%; 119/147) declared to have at least one emergency OR in their hospital; for the other 20/147 surgeons (13.6%), there is not a dedicated emergency operating room. Forty-six (68/147)% of the surgeons use the elective OR to perform emergency procedures during the day. The planning of an emergency surgical procedure is done by phone by 70% (104/147) of the surgeons. CONCLUSIONS: There is no dedicated emergency OR in the majority of hospitals internationally. Elective surgical procedures are usually postponed or even cancelled to perform emergency surgery. It is a priority to validate an effective universal triaging and scheduling system to allocate emergency surgical procedures. The new Timing in Acute Care Surgery (TACS) was recently proposed and validated by a Delphi consensus as a clear and reproducible triage tool to timely perform an emergency surgical procedure according to the clinical severity of the surgical disease. The new TACS needs to be prospectively validated in clinical practice. Logistics have to be assessed using a multi-disciplinary approach to improve patients' safety, optimise the use of resources, and decrease costs.

Protection provided by COVID-19 vaccines is compromised due to waning immunity over time. This study aimed to assess the level of antibodies anti-S-RBD of SARS-CoV-2 in a cohort of healthcare workers before and, on average, one and four months after the third dose of the BNT162b2 vaccine. The determination of antibodies was carried out in serum samples using an electrochemiluminescence immunoassay (ECLIA). All 34 participants (10 males, 24 females, 19 participants <50 years old, 15 participants ≥50 years old) showed a significant antibody level increase after the booster dose. Subsequently, a significant decrease in the antibody concentration was observed, with a reduction of about 60% after 150 days from the booster. Six subjects were infected by SARS-CoV-2 after the booster and showed a significantly higher antibody concentration on average four months after the third dose compared to naïve ones. Male and female participants had a similar trend in the antibody decline, while older subjects, compared to the younger ones, had a slightly slower decrease, even if they developed a lower level of antibodies after the third dose. These findings support the importance of the booster dose and underline the need for surveillance programs to better understand the antibody kinetics and optimize vaccination strategies.
RESUMEN
The SARS-CoV-2 pandemic led to the development of various vaccines. The BNT162b2 mRNA vaccine was the first approved due to its efficacy in eliciting a humoral immunity response after the second dose. However, a decrease in the antibody concentration was observed over time. Therefore, the administration of a third dose was scheduled, primarily for frail people and workers of essential public activities. The aim of this study was to assess the level of antibodies against the spike (S) RBD of SARS-CoV-2 in healthcare workers before and after the third dose of BNT162b2 vaccine, according to sex, age, and the time interval between vaccine doses and tests. All 37 (12 males, 25 females, 19 < 50 years old, 18 ≥ 50 years old) healthcare workers recruited showed a consistent antibody titer increase after the third dose. Data analysis showed that the antibody concentration before the third dose significantly decreased as the time interval up to the test increased, and a significantly higher level was shown in young than older people. Cluster analysis revealed that young females had a higher antibody level than older females before the third dose (p < 0.05). This study indicated the benefit of the third dose of BNT162b2 vaccine and its effect on leveling up the humoral immune response.
RESUMEN
Rhabdomyolysis is an uncommon complication of the coronavirus disease 2019 (COVID-19) infection. Previous reports have described its management and treatment in medical units, but have not discussed confirmatory tests or differential diagnosis. We report a case of a 58 year-old male patient, who was admitted for COVID-19 pneumonia and subsequently developed severe weakness, inability to move limbs, acute renal failure, significantly elevated myoglobin and creatinine kinase, and was diagnosed with rhabdomyolysis. Continuous renal replacement therapy, the treatment modality of choice over hyperhydration due to ongoing mechanical ventilation, was effective in resolving symptoms. No direct viral invasion of muscles was noted on biopsy. Here, we describe his symptoms, electromyography, and muscular biopsy results, and further discuss the possible differential diagnoses. Neuromuscular symptoms related to COVID-19 require careful clinical analysis. In addition, detailed reports of patients' course of illness and diagnoses will assist in improving care for affected patients.
RESUMEN
OBJECTIVE: To investigate the efficacy of nasal ciliary motility after radiofrequency ablation treatment in patients with isolated inferior turbinate hypertrophy and to clarify how long until normal ciliary function is restored. STUDY DESIGN: Prospective, single-group, pretest-posttest design. SETTING: Academic tertiary care medical center. SUBJECTS AND METHODS: This study involved 34 adult patients affected by nasal obstruction due to inferior turbinate hypertrophy who underwent radiofrequency ablation treatment between June and December 2014. Diagnosis was assessed according to clinical history, nasal endoscopy, and active anterior rhinomanometry. Cytologic samples were collected by nasal scraping before surgery and 1, 2, and 3 months after surgery. Ciliary motility was evaluated by nasal cytology with phase-contrast microscopy. Functional aspects of nasal mucosa were studied, with a focus on 3 parameters: (1) nasal mucociliary clearance, assessed by saccharin nasal transit time test; (2) percentage of ciliated cell motility, measured as the ratio between cells with motility and cells without motility; and (3) efficacy of ciliary motility, measured as the ratio between cells with valid motility and cells with hypovalid motility. RESULTS: Ciliary motility and ciliary efficacy showed a significant reduction after 1 and 2 months from surgery, returning to normal values within 3 months. No significant changes in saccharin nasal transit time were recorded during the follow-up. CONCLUSIONS: The outcomes of this study suggest that radiofrequency ablation treatment causes ciliary motility changes of nasal mucosa that are completely restored after at least 3 months after surgery. These cytologic abnormalities do not affect nasal functionality.

OBJECTIVES: To assess factors related to residual dizziness (RD) in patients who underwent successful canalith repositioning procedures (CRPs) for benign paroxysmal positional vertigo (BPPV). STUDY DESIGN: Prospective cohort study. SETTING: Academic center. SUBJECTS AND METHODS: Ninety-seven consecutive patients with BPPV of the posterior semicircular canal were initially enrolled. Diagnosis was assessed according to clinical history and bedside evaluation. All patients were treated with CRPs until nystagmus disappeared. Three days after the successful treatment, presence of RD was investigated. If RD was present, patients were monitored every 3 days until the symptoms disappeared. Subjects who required ≥4 CRPs or who failed to meet the follow-up visit were excluded. The Dizziness Handicap Inventory (DHI) was obtained from patients at the time of diagnosis and at every subsequent visit. RESULTS: At the end of selection, 86 patients were included; 33 (38.36%) reported RD after successful treatment. A significant difference in the incidence of RD was observed in consideration of the age of the subjects (P = .0003) and the DHI score at the time of diagnosis (P < .001). A logistic regression analysis showed that the probability of RD occurrence increased with the increase of the emotional subdomain score of the DHI questionnaire. CONCLUSION: RD is a common self-limited disorder, more frequent in the elderly, which may occur after the physical treatment for BPPV. The DHI score at the time of BPPV diagnosis represents a useful tool to quantify the impact of this vestibular disorder on the quality of life and to estimate the risk of RD after CRPs.

Parkinson's disease is a neurodegenerative disease that causes the death of dopaminergic neurons in the substantia nigra. The resulting dopamine deficiency in the basal ganglia leads to a movement disorder that is characterized by classical parkinsonian motor symptoms. Parkinson's disease is recognized as the most common neurodegenerative disorder after Alzheimer's disease. PD ethiopathogenesis remains to be elucidated and has been connected to genetic, environmental and immunologic conditions. The past decade has provided evidence for a significant role of the immune system in PD pathogenesis, either through inflammation or an autoimmune response. Several autoantibodies directed at antigens associated with PD pathogenesis have been identified in PD patients. This immune activation may be the cause of, rather than a response to, the observed neuronal loss. Parkinsonian motor symptoms include bradykinesia, muscular rigidity and resting tremor. The non-motor features include olfactory dysfunction, cognitive impairment, psychiatric symptoms and autonomic dysfunction. Microscopically, the specific degeneration of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies, which are brain deposits containing a substantial amount of α-synuclein, have been recognized. The progression of Parkinson's disease is characterized by a worsening of motor features; however, as the disease progresses, there is an emergence of complications related to long-term symptomatic treatment. The available therapies for Parkinson's disease only treat the symptoms of the disease. A major goal of Parkinson's disease research is the development of disease-modifying drugs that slow or stop the neurodegenerative process. Drugs that enhance the intracerebral dopamine concentrations or stimulate dopamine receptors remain the mainstay treatment for motor symptoms. Immunomodulatory therapeutic strategies aiming to attenuate PD neurodegeneration have become an attractive option and warrant further investigation.

The purpose of this study is to assess the feasibility of endoscopic-assisted myringotomy and ventilation tube insertion in adults affected by chronic otitis media with effusion, comparing the outcomes of this approach with those obtained with the traditional microscopic technique. Twenty-four patients were enrolled in this trial and alternately assigned to 2 groups of 12 subjects each. In group A, patients underwent myringotomy and ventilation tube insertion under endoscopic view, whereas in group B, the same procedure was performed traditionally using a microscope. All cases were evaluated 1 week after surgery and then monthly until tube extrusion. Type A tympanogram was achieved in 10 of 13 ears in both groups (76.92%). No significant difference in operative times or complication rates was observed (P > .05). Endoscopic technique could be a viable alternative to the microscopic approach for myringotomy and ventilation tube positioning in adults affected by chronic otitis media with effusion.

OBJECTIVE: Tobacco smoke is a significant risk factor for respiratory diseases. The purpose of this study is to analyze the cytologic and functional features of nasal mucosa in smokers, nonsmokers, and ex-smokers to evaluate if nasal alterations in smokers are permanent or reversible conditions after smoking cessation. STUDY DESIGN: Case series with planned data collection. SETTING: University medical center. SUBJECTS AND METHODS: Ninety healthy volunteers recruited from the staff of Alfredo Fiorini Hospital, Sapienza University of Rome, were enrolled in this prospective study from October to November 2013. We divided the cases according to smoking habits (smokers, nonsmokers, ex-smokers). Each group was composed of 30 subjects. Cytologic features of nasal mucosa and effectiveness of nasal mucociliary clearance were studied, focusing on 4 parameters: (1) nasal mucociliary clearance, assessed by saccharin nasal transit time; (2) ratio between the number of ciliated cells and goblet cells, analyzed by microscopic observation of cytologic specimens of nasal mucosa that had undergone May Grunwald Giemsa staining; (3) evaluation of ciliary motility; and (4) time of ciliary movement of ciliated cells analyzed by phase-contrast microscopy. RESULTS: All parameters were significantly reduced in the smokers compared to the nonsmokers. There were no statistically significant differences between the nonsmoker and ex-smoker groups. CONCLUSION: Cigarette smoking causes cytologic modifications of nasal mucosa that influence the effectiveness of mucociliary clearance. Our preliminary study suggests that these changes are not permanent and that nasal mucosa of ex-smokers recovers normal cytologic and functional features.

A 69-year-old woman with mucoepidermoid carcinoma (MEC) of the tongue base came under our observation complaining of repeated episodes of haemoptysis. Mucoepidermoid carcinoma of the tongue base gives rise to a rather vague and aspecific symptomatology. Early symptoms include foreign body sensation in the oral cavity, undefined paraesthesia, and sialorrhoea. With the progression of disease, dysphagia, otalgia, and painful swallowing are usually referred. We report a case of mucoepidermoid carcinoma of the tongue base mimicking an ectopic thyroid.
RESUMEN
The aim of this prospective study is to establish whether ductoplasty is necessary to repair the Wharton's duct after a combined endoscopic and external approach to remove large submandibular gland stones or if simple suturing of the oral floor mucosa after stent placement may be sufficient to achieve proper duct healing. Ten patients were enrolled. Ductoplasty was performed in 6 cases, whereas in 4 cases, only the mucosa of the oral floor was sutured. The stent was removed about 3 weeks after surgery. Sialoliths were completely removed in all cases. During follow-up, patient symptom evaluation, ultrasound, and physical examination showed no signs of recurrence or complications. In our limited experience, ductoplasty after the combined approach was not necessary. After stent placement, the mere suture of the oral mucosa overlying the damaged ductal wall allowed a correct recanalization of the ductal lumen as commonly observed after careful ductoplasty.

A parotid fistula is a rare and extremely unpleasant condition. In this paper, we present the case of a 53-year-old woman with a diagnosis of posttraumatic fistula of the parotid gland. After exclusion of other therapeutic alternatives, it was decided to use transdermal scopolamine patches at sustained release (Scopoderm TTS). This technique consists in the application every three days of a patch with 1.5 mg of scopolamine in the area of the mastoid apophysis; the patch releases a dose of 0.5 mg of the active substance over each 24-hour period. The patient underwent periodic clinical followup over a period of three years, achieving satisfactory results with no significant adverse effects.
