Abstract
Introduction and objectives

Long-term follow up of patients with hyper IgE syndrome (HIES), as a primary immunodeficiency disorder, has been poorly investigated. This study describes common clinical and immunological features of patients with HIES in the last 10 years in Shiraz University of Medical Sciences, Shiraz, Iran.

Methods and patients

In this cross-sectional study, the symptoms and medical records of 18 patients, who were diagnosed with HIES, were observed. Genetic and immunologic study was also performed.

Results

Eighteen patients with the mean age of 13 years old were investigated. Ten patients were detected to have mutations in DOCK8 gene and autosomal recessive HIES (AR-HIES); and four patients were found with STAT3 mutation and autosomal dominant HIES (AD-HIES). So, 14 patients with known genetic results were considered for further data analysis. Food allergy, eczema, viral and skin infections were the major complications of AR-HIES patients. The major clinical complications of AD-HIES patients were pneumonia, skin infections and eczema. Food allergy and viral infection were significantly higher in DOCK8 deficient patients. The most common causes of hospitalization in both AR-HIES and AD-HIES patients were pneumonia, skin infections and sepsis. The most common cause of death was found to be sepsis.

Conclusions

AD-HIES and AR-HIES cannot be differentiated only based on the clinical presentations. Genetic features are also necessary for better diagnosis. This study, summarizing the clinical, immunological and genetic information of the patients with AD-HIES and AR-HIES, may open a way for better diagnosis and management of HIES.

Immune response and evasion mechanisms in lip carcinogenesis: an immunohistochemical study

Publication date: Available online 29 September 2018

Author(s): Maria Luiza Diniz de Sousa Lopes, Amanda Katarinny Goes Gonzaga, Carla Mosconi, Gustavo Martelli Palomino, Elismauro Francisco Mendonça, Aline Carvalho Batista, Éricka Janine Dantas da Silveira

Abstract
Objectives

Programmed death ligand-1 (PD-L1) and human leukocyte antigen-G (HLA-G) are considered immune checkpoint molecules that inhibit T-cell effectiveness, contributing to tumor immune escape. This study investigated PD-L1, HLA-G, CD8, and granzyme B (GrB) expression at different stages of lip carcinogenesis.

Design and results

Forty cases of lip squamous cell carcinoma (LSCC), 55 actinic cheilitis (AC), and 10 healthy lip mucosa (HLM) were submitted to immunohistochemistry. Semiquantitative (PD-L1, HLA-G), and quantitative (CD8, GrB) analysis were performed. PD-L1 and HLA-G expression in neoplastic cells/keratinocytes and stroma/connective tissue was significantly higher in LSCC and AC, compared to HLM (p<0.05). PD-L1 was not associated with clinicopathological features of the lesions. HLA-G expression by malignant cells was significantly higher in LSCCs with distant metastasis (p = 0.041).CD8+ and GrB+ cell numbers progressively increased from HLMs to LSCC, with AC exhibiting intermediate numbers (p<0.01). Most LSCCs showed coexistence of PD-L1+ and CD8+ cells (72.5%). PD-L1 was directly correlated to CD8+ and GrB+ lymphocytic infiltration in LSCCs (p<0.05). Low cytotoxic immune response was associated with lymph node metastasis in LSCC (p<0.05).

Conclusions

PD-L1 and HLA-G-mediated immune evasion mechanisms are likely to occur from early pre-malignant to advanced malignant stages of lip carcinogenesis, which might provide a rationale for therapeutic blockade of these pathways. PD-L1 expression in LSCCs was correlated with the cytotoxic markers, suggesting that that PD-L1 may appear as an escape mechanism in response to an active antitumor response.

Individual Reliability of the Standard Clinical Method vs Patient-Centered Tinnitus Likeness Rating for Assessment of Tinnitus Pitch and Loudness Matching.

JAMA Otolaryngol Head Neck Surg. 2018 Sep 27;:

Authors: Hébert S

Abstract
Importance: Current individualized sound therapies for tinnitus rely on tinnitus pitch assessment, which is commonly derived from the standard clinical 2-alternative forced-choice (2-AFC) approach driven by the examiner. However, this method is limited by lack of individual test-retest reliability and focuses on a single rather than multiple tinnitus frequencies.
Objective: To assess individual test-retest reliability of the 2-AFC, with a single final frequency (and corresponding loudness), and the tinnitus likeness rating (TLR), with the participant exposed to the entire audible frequency spectrum, from which 3 dominant frequencies and corresponding loudness were extracted.
Design, Setting, and Participants: In this case series, participants with tinnitus underwent testing twice with both methods at a 1-month interval by experienced clinicians from January 6 through March 17, 2017. Each clinician tested each patient only once at visit 1 or 2 in a university audiology training setting with standardized equipment and was blind to previous assessment. Participants with bilateral or unilateral chronic tinnitus for longer than 6 months, in good health, without total deafness in either ear, and without cerumen in the ear canal were recruited through advertisements (community and clinics) and word of mouth (volunteer sample). The audiologists were likewise participants in the planned comparison between TLR and 2-AFC in the test-retest measures.
Main Outcomes and Measures: Test-retest concordance with 95% CIs for each method, calculated as the proportion of participants with the same final frequency between the 2 visits (2-AFC) or with at least 1 concordant dominant frequency (TLR) as well as loudness differences of no greater than 10 dB.
Results: The study sample included 31 participants (55% men; mean [SD] age, 50.7 [13.7] years). For TLR, 26 of 31 participants had at least 1 concordant dominant frequency between the 2 visits (proportion, 0.84; 95% CI, 0.66-0.95), whereas for 2-AFC, 7 of 31 participants had a concordant final tinnitus pitch in either ear (proportion, 0.23; 95% CI, 0.10-0.41). Loudness reliability followed the same pattern, with more concordant loudness levels in the TLR (proportion, 0.73; 95% CI, 0.52-0.88) than in the 2-AFC (proportion, 0.40; 95% CI, 0.05-0.85). Mean time taken to complete the tests was less than 15 minutes, and general appreciation by participants with tinnitus and audiologists were overall similar for both.
Conclusions and Relevance: Superior test-retest concordance can be demonstrated at the individual level using the several dominant frequencies extracted from the patient-centered TLR.

Understanding Risk Factors Associated With Unplanned Reoperation in Major Head and Neck Surgery.

JAMA Otolaryngol Head Neck Surg. 2018 Sep 27;:

Abstract
Importance: Understanding the preoperative, intraoperative, and postoperative risk factors of reoperation is the optimal way to approach decreasing its incidence.
Objective: To identify risk factors of unplanned reoperation following major operations of the head and neck.
Design, Setting, and Participants: This retrospective cohort study queried the American College of Surgeons National Surgical Quality Improvement Program database and identified 2475 cases of major operations of the head and neck performed between 2005 and 2014. Specific operations analyzed were glossectomy, mandibulectomy, laryngectomy, and pharyngectomy. Univariate and multivariate analyses were performed to compare demographic and clinical characteristics of patients with or without unplanned reoperation. Data were analyzed between September and November 2017.
Main Outcomes and Measures: The primary outcome was incidence of unplanned reoperation in patients with major operations in the head and neck region. An additional aim was to assess the risk factors associated with an increased likelihood of reoperation.
Results: In total, 1941 patients were included in this study (1298 [66.9%] males), with most patients (961 [49.5%]) between 61 and 80 years of age. The overall unplanned reoperation rate within 30 days after the principal operative procedure was 14.2% (275 patients). The operative procedure with the highest reoperation rate was pharyngectomy (8 of 46 [17.4%]), followed by glossectomy (95 of 632 [15.0%]), laryngectomy (53 of 399 [13.3%]), and mandibulectomy (25 of 240 [10.4%]). Among the unplanned reoperation patients, 516 patients (76.8%) underwent reoperation during their initial hospital admission and 156 patients (23.2%) after readmission. The mean (SD) number of days from the principal operative procedure to unplanned reoperation was 8.5 (3.6) days for initial-admission reoperations and 16.0 (4.8) days for readmission reoperations. The most common unplanned reoperation procedures overall included repair, surgical exploration, and revision procedures on arteries and veins (47 of 2475 [1.9%]), incision procedures on the soft tissue of the neck and thorax (37 of 1941 [1.9%]), and incision and drainage procedures on the skin, subcutaneous, and accessory structures (21 of 1941 [1.1%]). Multivariate analysis results indicated that the independent risk factors for unplanned reoperation following a major cancer operation of the head or neck included black race (odds ratio [OR], 1.72; 95% CI, 1.09-2.74), disseminated cancer (OR, 1.85; 95% CI, 1.14-3.00), greater total operation time (OR, 2.05; 95% CI, 1.49-2.82), superficial (OR, 2.56; 95% CI, 1.55-4.24) or deep (OR, 4.83; 95% CI, 2.60-8.95) surgical site infection, wound dehiscence (OR, 8.36; 95% CI, 5.10-13.69), and ventilator dependence up to 48 hours after surgery (OR, 2.95; 95% CI, 1.79-4.87).
Conclusions and Relevance: The identification of a significant association of black race, disseminated cancer, total operation time, surgical site infection in either the superficial or deep spaces, wound dehiscence, or ventilator dependence for more than 48 hours after surgery with increased risk of reoperation in major head and neck surgery may guide the modification and adaptation of these risk factors to decrease the burden that unplanned reoperation places on patients, surgeons, and the health care system.
