INTRODUCTION: Adenoidectomy is one of the most commonly performed pediatric operations worldwide. There are a proportion of children who require revision adenoidectomy. Yet there is little in the literature about the incidence, associated factors and etiology of adenoidal regrowth. The aim of this retrospective cohort study was to determine incidence and factors associated with revision adenoidectomy. METHODS: An extraction of all hospital morbidity records belonging to patients under the age of 18 years who underwent one or more adenoidectomy procedures (with or without tonsillectomy) between January 1, 2000 and June 2016 at a tertiary care children's hospital was performed...

BACKGROUND/PURPOSE: Basal cell adenoma (BCA) and basal cell adenocarcinoma (BCAC) are uncommon salivary gland tumors comprising proliferation of basaloid cells. Nuclear β-catenin expression and mutations in its encoding gene (CTNNB1) are reported to be specific to BCA. PIK3CA mutations are only found in BCAC not in BCA. However, in previous studies the number of cases was relatively small. The present study analyzed 44 cases of basal cell neoplasms to identify the CTNNB1 and PIK3CA mutation profiles in this rare salivary gland tumor...

Dengue is a major global disease requiring improved treatment and prevention strategies. The recently licensed Sanofi-Pasteur Denvaxia vaccine does not protect children under the age of nine and additional vaccine strategies are thus needed to halt this expanding global epidemic. Here, we employed a molecular engineering approach and plant-expression to produce a humanised and highly immunogenic Poly-Immunoglobulin G Scaffold (PIGS) fused to the consensus dengue envelope protein III domain (cEDIII). The immunogenicity of this IgG Fc receptor targeted vaccine candidate was demonstrated in transgenic mice expressing human FcγRI/CD64, by induction of neutralising antibodies and evidence of cell-mediated immunity...

Background: Intraoperative consultation is an important tool for the evaluation of the upper aerodigestive tract (UAT) malignancies. Although frozen section analysis is a preferred method of intra-operative consultation, however in resource limited countries like Pakistan, this facility is not available in most institutes; therefore, we aimed to evaluate the diagnostic accuracy of touch imprint cytology for UAT malignancies using histopathology of the same tissue as gold standard. Methods: The study involved 70 cases of UAT lesions operated during the study period...

Adenoid cystic carcinoma (ACC) is generally treated with surgical resection followed by postoperative radiotherapy. In cases where surgical management is precluded due to the location of the tumor and/or patient factors, radiation therapy can be offered to achieve local control. Here, we present a case of unresectable Stage T4N0 ACC of the nasopharynx with skull base and intracranial extension treated with intensity modulated proton therapy (IMPT), which achieved good local control with no significant late toxicity...

Adenoid cystic carcinoma (ACC) is a rare cancer, and there are no standard-of-care treatments for patients with metastatic ACC. We herein report a patient with lung metastasis of ACC who achieved a favorable response to levetiracetam. A 52-year-old Japanese man was admitted to our hospital because of multiple lung metastases of ACC. We performed first-line chemotherapy with cisplatin plus gemcitabine, and subsequently oral S-1 as second-line chemotherapy, which resulted in disease progression. The patient developed symptomatic epilepsy and received levetiracetam (250 mg twice daily)...

Breast adenoid cystic carcinoma (AdCC), a rare type of triple-negative breast cancer (TNBC), has been shown to be driven by MYB pathway activation, most often underpinned by the MYB-NFIB fusion gene. Alternative genetic mechanisms, such as MYBL1 rearrangements, have been reported in MYB-NFIB-negative salivary gland AdCCs. Here we report on the molecular characterization by massively parallel sequencing of four breast AdCCs lacking the MYB-NFIB fusion gene. In two cases, we identified MYBL1 rearrangements (MYBL1-ACTN1 and MYBL1-NFIB), which were associated with MYBL1 overexpression...

This paper attempts to identify the sources and evaluate the prevalence of halitosis in children with adenoid hypertrophy. The study included pediatric patients admitted for adenoidectomy due to obstructive symptoms. Patients with possibly other causes of halitosis, were excluded from the study. Halitosis was detected in 30 out of 136 children (22.1%). The effect of adenoid hypertrophy on halitosis was confirmed by the significant reduction in the organoleptic score rated according to the Rosenberg Scale (on average by 2 degrees) and the levels of volatile sulfur compounds (VSCs) (on average 84 ppb) post-adenoidectomy, as compared to pre-surgery results...
