OBJECTIVE: Introduction: Salivary glands have a significant impact on the state of the homeostasis of the human body, oral cavity in particular, sensitively responding to pathological processes. The reactivity of the salivary glands in response to pathological processes that are organically linked to morphology and functions of the organ's structures, and particularly the excretory ducts of the glands and their microcirculatory blood flow, is one of the problems which have not been solved to date...

Background Rhinitis is a highly prevalent yet often misdiagnosed condition. Patients who have local allergic rhinitis are regularly mislabeled as having a nonallergic etiology. Thus, a highly accurate, reproducible, and noninvasive assessment, which can be performed quickly and with minimal discomfort to the patient, is required. Objective The aim of this research was to identify the efficiency of various nasal brushes as tools for harvest and collection of epithelial proteins and its suitability for identification of rhinitis...

PURPOSE: The aggressive behavior of salivary duct carcinoma (SDC) necessitates an aggressive treatment strategy, including surgery and radiotherapy (RT). We evaluated practice patterns and treatment outcomes in patients with SDC treated in our Institute. METHODS: Patients with SDC of the parotid or submandibular gland treated with curative intention in our Institute from 1998 until 2016 were reviewed. Our diagnostic workup and treatment strategy were evaluated together with treatment outcomes...

Background: The thyroid gland is resistant to microbial infection, because of its organ characteristics such as encapsulation, iodine content, and rich blood supply. Therefore, acute suppurative thyroiditis (AST), as a bacterial infection of the thyroid gland, is rarely seen. AST typically takes places on the left side the neck region in children, because of the coincidence of the left piriform sinus fistula, as a most common route of infection. AST is also usually seen in immunocompromised hosts...

Immunohistochemistry (IHC) is used to help differentiate pleural mesothelioma from pulmonary adenocarcinoma in pleural biopsies and cytology specimens of pleural effusions due to overlapping morphologic features between these two malignancies. The aim of this study is to evaluate IHC glypican-1, a recently proposed marker for epithelioid mesothelioma, in our cohort of mesotheliomas and pulmonary adenocarcinoma. Tissue microarrays with duplicate cores from 33 cases of mesotheliomas (28 epithelioid type and five sarcomatoid type) and 21 cases of pulmonary adenocarcinoma were stained with glypican-1 antibody...

BACKGROUND: The paradigm shift from cytological screening to Human Papillomavirus (HPV)-based screening for cervical cancer allows the introduction of new technologies in sample collection and diagnostics. The OncoE6™ Cervical Test (OncoE6 Test) is a rapid, easy-to-use lateral flow method detecting HPV16/18 E6 oncoproteins that has proven to detect high-grade cervical lesions with high specificity. If compatible with self-collection samples, this technology might allow for decentralized screening of hard-to-reach populations...

For studies requiring accurate conception-timing, reliable, efficient methods of detecting oestrus reduce time and costs, whilst improving welfare. Standard methods use vaginal cytology to stage cycle, and breeders are paired-up using approximately five proven females with proven males to achieve at least one conception on a specific day. We describe an alternative, fast, consistent, non-invasive method of timed-mating using detection of lordosis behaviour in Wistar and Lister-Hooded rats that used unproven females with high success rates...

A 20-month-old female spayed Staffordshire Terrier (22.3 kg) presented to the Orthopedic Surgery Service at North Carolina State University Veterinary Teaching Hospital for evaluation of a 6-week history of toe-touching to nonweight-bearing lameness in the right hind limb. Radiographs of the right stifle revealed a multiloculated lytic lesion of the distal femur, with a large open lytic zone centrally, numerous osseous septations peripherally, and focal areas of cortical thinning and loss. An aspirate of the right distal femoral lesion yielded mildly cloudy serosanguineous fluid...

Poroid hidradenoma (PH) is a rare, benign neoplasm of the skin appendages of either eccrine or apocrine derivation. It typically presents as an isolated, well-circumscribed, painless nodule most commonly in the head and neck region and limbs. It is described as a tumour with the architecture of a hidradenoma and cytological features of poroma 1 . This article is protected by copyright. All rights reserved.

A 64-year-old man was admitted with acute onset disturbed consciousness. Cerebrospinal fluid analysis revealed pleocytosis and elevated protein, with negative cultures and PCR. Serum antibodies for autoimmune encephalitis were also negative. Brain magnetic resonance imaging (MRI) was unremarkable, but whole-body CT scan showed a tumor in the left lower lung lobe. Bronchial brush cytology demonstrated clusters of malignant cells, and 18 F-fluorodeoxyglucose positron emission tomography showed multiple lesions and increased uptake in the lung tumor...

REVIEW
Yung-Taek Ouh, Jae Kwan Lee
Eradication of cervical cancer involves the expansion of human papillomavirus (HPV) vaccine coverage and the development of efficient screening guidelines that take vaccination into account. In Korea, the HPV National Immunization Program was launched in 2016 and is expected to shift the prevalence of HPV genotypes in the country, among other effects. The experiences of another countries that implement national immunization programs should be applied to Korea. If HPV vaccines spread nationwide with broader coverage, after a few decades, cervical intraepithelial lesions or invasive cancer should become a rare disease, leading to a predictable decrease in the positive predictive value of cervical screening cytology...

BACKGROUND Acquired hemophilia A (AH) is a rare hemorrhagic diathesis, characterized by the presence of autoantibodies directed against the pro-coagulant activity of factor VIII. It is associated with rheumatoid arthritis (RA) in 4% to 8% of cases and its prognosis remains severe. CASE REPORT A 66-year-old patient has been followed up for 20 years for deforming and severe RA, which was in low-disease activity. However, the patient presented a polyarticular flare involving the metacarpophalangeal and the proximal interphalangeal joints, the left elbow, and the right knee, which was warm and swollen...

Temozolomide, a key drug in the treatment of malignant glioma, can cause profound lymphopenia and various opportunistic infectious diseases. A 79-year-old woman with anaplastic oligodendroglioma developed a fever and gross hematuria after 8 weeks of standard radiotherapy with concomitant temozolomide treatment. A cytomegalovirus (CMV) antigen test for pp65 antigenemia was positive (137 cells per 75,800 leukocytes), and the findings from a urine cytology test were consistent with CMV-induced hemorrhagic cystitis...

Maternal transmission of intracellular microbes is pivotal in establishing long-term, intimate symbioses. For germline microbes that exert negative reproductive effects on their hosts, selection can theoretically favor the spread of host genes that counteract the microbe's harmful effects. Here, we leverage a major difference in bacterial (Wolbachia pipientis) titers between closely related wasp species with forward genetic, transcriptomic, and cytological approaches to map two quantitative trait loci that suppress bacterial titers via a maternal effect...

PURPOSE: Surgical biopsy examination is the gold standard for the diagnosis of lymph node lymphomas. Fine-needle aspiration cytology (FNAC) is a quick and safe method in the management of cervical lymph nodes. Its value in confirming recurrent or residual lymphoma is well established. However, its role in the primary diagnosis of lymph node lymphoma remains controversial. The aim of this study was to assess, in our experience, the reliability of FNAC in the diagnosis of cervical lymph node lymphomas...

Even though cytology remains the gold standard to assess the nature of thyroid nodules, up to 30% of the results are indeterminate (BethesdaIII and IV). In these cases, current guidelines recommend performing diagnostic surgery, which proves malignancy in only 15-30% of cases. A more precise method is needed to avoid unnecessary surgeries, surgical complications and costs in the process of diagnosing indeterminate nodules. Complementary use of molecular profiling tests seems to help in this complex scenario...

BACKGROUND: Studies on parotid gland ultrasound assessments performed specifically by surgeons are seldom reported. METHODS: Retrospective series of a single academic surgeon experience, analyzing 70 new parotid masses with evaluable preoperative SP-US characteristics, location measurements, and perioperative events. RESULTS: 31/70 masses were malignant. SP-US characteristics significantly associated with both malignancy and positive margins included extraparenchymal extension, irregular borders, hypervascularity, infiltration, and the lack of deep enhancement...
