RESUMO
BACKGROUND: Identifying predictive factors of the cochlear implant outcomes in pediatric patients is critical in guiding tailored rehabilitation programs. The study aimed to assess cochlear implant outcomes, identify predictors, and highlight decision-making factors and barriers to quality care. METHODS: This cross-sectional study included parents of children who received unilateral cochlear implants for bilateral severe- to- deep sensorineural hearing loss. Inclusion criteria were age ≤ 5 years and intelligence quotient (IQ) Scores ≥ 85, A pre-designed structured questionnaire was used to collect data from parents/guardians of the children attending follow-up. The Arabic validated Glasgow Children Benefit Inventory score was used to assess the health-related quality of life (QOL) after intervention. RESULTS: The quality of life (QOL) score (outcome) after surgery was positive in all cases. Multivariate analysis showed that the site of operation (Bahtim hospital and Ain Shams Hospital [AOR(95% confidence interval CI), 5.7 (1.4-23), 5 (1.4-17.9), p = 0.015, 0.013, respectively]), education of the father (university/postgraduate [AOR (95% CI): 5 (1.4-17.9), p = 0.013]), the parents' expectation that their child would be able to participate in regular classroom activities [AOR (95% CI): 8.9 (3.7-21.3), p < 0.001], and history of Attention deficit/hyperactivity disorder (ADHD), perinatal hypoxia, and low birth weight [AOR (95% CI): 2.5 (1.2-5.1), 3.7 (1.7-8.1), 4.7 (2.1-10.5), p = 0.013, 0.001, ≤ 0.001, respectively] are significant independent predictors of good outcome. CONCLUSION: All parents expressed a positive change in their child's QOL. Almost all parents of children with cochlear implants face many barriers in obtaining quality healthcare services for their children. Parents, especially those with lower schooling, should receive good counselling to increase their confidence in their children's capabilities and maximize benefits of regular follow-up. Improving the quality of healthcare centers is recommended.
RESUMO
BACKGROUND: P D-L1 is expressed in tumor cells and plays a crucial role in tumor immune escape. Tumor-infiltrating lymphocytes (TILs) as CD8 T cells contribute to reduced tumor growth. Few studies investigated the prognostic effect of PD-L1 and CD8 TILs in ovarian high-grade serous carcinoma (HGSC). In the present study, we analyzed the expression of PD-L1 and CD8 TILs in HGSC by immunohistochemistry, and results were correlated to prognosis. It was carried on 54 cases of ovarian HGSC who attended the Oncology Centre, Mansoura University, Egypt, from 2012 till 2019. RESULTS: Nearly 60% of cases showed positive PD-L1 expression in tumor cells. Regarding the clinicopathological characteristics, higher PD-L1 expression was found among patients with residual tumor (82.4%) compared to patients with no residual tumor (54.5%), with marginal statistical significance (p 0.07). PD-L1 was significantly associated with CD8 TILs expression. Higher PD-L1 expression was found among tumors with low expression of CD8 TILs with statistically significant difference (p≤0.001). Disease-free survival (DFS) was significantly lower among the group with positive expression of PD-L1 compared to the group with negative expression of PD-L1 (p 0.01), while overall survival (OS) was not associated with PD-L1 expression. On the other hand, the overall survival (OS) in patients with high CD8 expression was significantly higher than patients with low CD8 expression (p 0.043), while DFS was not significantly different among both CD8 TILS groups. CONCLUSIONS: PD-L1 and CD8 TILs may become a promising therapeutic target for patients with ovarian HGSC. More studies are needed to further validate their prognostic effect. Precise identification of patients who will benefit from PD-L1 checkpoint blockade and TILs adaptive immunotherapy is mandatory.

BACKGROUND: Cancer and pulmonary tuberculosis are major global health concerns and are associated with substantial morbidity and mortality. The association between active tuberculosis and subsequent cancer development has been investigated for many years. This study was planned to determine the prevalence of latent tuberculosis infection in patients with recently diagnosed bronchogenic carcinoma. METHODS: Sixty-four newly diagnosed primary lung cancer patients were enrolled. Diagnosis of latent tuberculosis infection was performed with QuantiFERON-TB Gold In-Tube tests, with exclusion of active tuberculosis. RESULTS: Latent tuberculosis infection was detected in 16 (25%) patients, and 8 (12.5%) had indeterminate results of the QuantiFERON-TB Gold In-Tube test. Being a current smoker was associated with a higher prevalence of latent tuberculosis (p = 0.001). Comorbidities, tumor site, and histopathology were not associated with latent tuberculosis infection. CONCLUSIONS: There is a considerable risk of concurrent latent tuberculosis in newly diagnosed primary bronchogenic carcinoma. The need for treatment of latent tuberculosis in these patients and its influence on the outcome and prognosis are issues for further investigations.

INTRODUCTION: Inducible laryngeal obstruction (ILO) is an important cause of a variety of respiratory symptoms and can mimic bronchial asthma (BA). This study was planned to measure the prevalence of ILO among patients diagnosed with BA and to detect its effect on BA control and severity. MATERIAL AND METHODS: Patients aged 18 years or older who were previously diagnosed with BA were enrolled. Laryngeal obstruction was induced using the patient's specific trigger (e.g. exercise). Visualization of vocal folds was accomplished using a 70-degree rigid laryngoscope (Karl Storz). A visual grade score was utilized to determine the severity of laryngeal obstruction. RESULTS: Results showed that 38.3% (n = 46) of the patients had ILO with the majority being classified as grade 2 (80.4%) (n = 37). The most common subtype was glottic ILO (63%). Bronchial asthma duration, level of control, and severity were not associated with ILO (P values: 0.2, 0.3 and 0.8 respectively). CONCLUSION: Asthma and ILO commonly co-exist. An accurate classification of patients is very important and must be considered in order to determine whether the symptoms are directly related to ILO or whether they are caused by BA. Ceasing inappropriate treatment may be necessary. Objective diagnostic modalities of ILO are essential.

BACKGROUND: Calretinin (CR), a known mesothelial marker, is expressed in both epithelial and mesenchymal malignancies including breast cancer. AIMS: We aimed to measure the frequency of CR expression in correlation with other clinicopathological parameters of different molecular subtypes of invasive breast carcinoma and to study its prognostic implications in this common cancer. STUDY DESIGN: Tissue microarrays were constructed from 225 tissue samples of breast carcinoma cases. SUBJECTS AND METHODS: Immunostaining for CR in addition to estrogen receptors, progesterone receptors, human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor, CK5/6, and Ki-67 for molecular subtyping. STATISTICAL ANALYSIS USED: Chi-square and Fisher's exact tests were done using SPSS 18.0 software (IBM Inc.). Survival data were analyzed using Kaplan-Meier test, Log-rank test, and Cox proportional hazard models. RESULTS: Cases of invasive breast carcinomas with different grades were classified into 84 luminal A, 45 luminal B, 27 HER2 positive, 40 basal-like, and 29 unclassified. High CR expression was associated with tumors of high grade (P < 0.0001), high locoregional recurrence (P = 0.005), hormonal receptors negative, and high Ki-67 indices. They frequently display a basal-like phenotype (70%, P < 0.0001), HER2 (59.3%), and luminal B (33.3%) tumors compared to luminal A (9.5%) and unclassified subtypes (17.2%). Moreover, it is associated with poor overall patient survival (P = 0.034), but it does not affect disease-free survival. CONCLUSIONS: Calretinin could be a reliable predictor marker of adverse prognosis in breast cancer.
