Microsecretory Adenocarcinoma of Salivary Glands: An Expanded Series of 24 Cases.

Head Neck Pathol 2021 May 12. Epub 2021 May 12.

Department of Pathology, UT Southwestern Medical Center, Dallas, TX, USA.

Microsecretory adenocarcinoma (MSA) is a recently described salivary gland tumor with a characteristic histologic and immunophenotypic profile and recurrent MEF2C-SS18 fusions. Because only six cases of MSA have been published, its complete clinicopathologic spectrum is unclear, and its biologic behavior has not been documented. Here, we present an updated and expanded experience of 24 MSA cases. All cases of MSA were obtained from the authors' files. Immunohistochemistry for S100, SOX10, p63, p40, SMA, calponin, and mammaglobin was performed. Molecular analysis was performed by targeted RNA sequencing, SS18 break apart fluorescence in situ hybridization, and/or reverse transcriptase polymerase chain reaction for MEF2C-SS18 fusion. Clinical follow-up was obtained from medical records. A total of 24 MSA cases were collected, from 13 women and 11 men, ranging from 17 to 83 years (mean 49.5 years). The vast majority (23 of 24) arose in the oral cavity, with the palate (n = 14) and buccal mucosa (n = 6) as the most frequent subsites. Tumors showed consistent histologic features including: (1) microcystic tubules, (2) flattened intercalated duct-like cells, (3) monotonous oval hyperchromatic nuclei, (4) abundant basophilic luminal secretions, (5) fibromyxoid stroma, and (6) circumscribed borders with subtle infiltration. The tumors were very consistently positive for S100 (24 of 24), p63 (24 of 24), and SOX10 (14 of 14) and negative for p40 (0 of 21), calponin (0 of 12) and mammaglobin (0 of 16), while SMA (4 of 20) was variable. MEF2C-SS18 fusion was demonstrated in 21 of 24 cases; in the remaining 3 cases with insufficient RNA, SS18 break apart FISH was positive. Treatment information was available in 17 cases, all of which were managed with surgery only. In 14 cases with follow-up (1-216 months, mean 30), no cases recurred or metastasized. MSA is a distinct salivary gland neoplasm with remarkably consistent clinical, histologic, immunophenotypic, and genetic features that generally behaves in an indolent manner following surgery alone. These observations solidify MSA as a unique, low-grade salivary gland carcinoma that warrants inclusion in the next version of the WHO classification of head and neck tumors.

Contextual diversity facilitates learning new words in the classroom.

PLoS One 2017 6;12(6):e0179004. Epub 2017 Jun 6.

Universitat de València, Valencia, Spain.

In the field of word recognition and reading, it is commonly assumed that frequently repeated words create more accessible memory traces than infrequently repeated words, thus capturing the word-frequency effect. Nevertheless, recent research has shown that a seemingly related factor, contextual diversity (defined as the number of different contexts [e.g., films] in which a word appears), is a better predictor than word-frequency in word recognition and sentence reading experiments. Recent research has shown that contextual diversity plays an important role when learning new words in a laboratory setting with adult readers. In the current experiment, we directly manipulated contextual diversity in a very ecological scenario: at school, when Grade 3 children were learning words in the classroom. The new words appeared in different contexts/topics (high-contextual diversity) or only in one of them (low-contextual diversity). Results showed that words encountered in different contexts were learned and remembered more effectively than those presented in redundant contexts. We discuss the practical (educational [e.g., curriculum design]) and theoretical (models of word recognition) implications of these findings.

Sialolipoma of minor salivary glands: presentation of five cases and review of the literature with an epidemiological analyze.

Indian J Otolaryngol Head Neck Surg 2015 Mar 1;67(Suppl 1):105-9. Epub 2014 Nov 1.

Laboratory of Oral Pathology, Postgraduate and Research Division, Dental School, National Autonomous University of Mexico, Mexico City, Mexico ; Laboratorio de Patología Clínica y Experimental, División de Estudios de Postgrado e Investigación, Facultad de Odontología, Universidad Nacional Autónoma de México, Circuito Institutos s/n, Ciudad Universitaria, 04510 Coyoacan, D. F. Mexico.

Unlabelled: Sialolipoma is rare benign neoplasm arise from salivary glands (majors and minors) characterized by neoplastic adipose tissue with scattered non-neoplastic salivary gland acinus. To date 60 cases (including 5 cases reported in the present paper) have been reported in scientific literature. This article presents 5 new cases of sialolipoma affecting minor salivary glands (MiSG) and additionally reviews and analyzes the previously published cases to assess possible demographical differences between sialolipoma from minor and from major salivary glands.

Case Reports: 5 cases (3 females; 2 males; age means 63.8 years), of sialolipoma from MiSG, are reported. 2 of them were located in buccal mucosa, 1 in upper lip mucosa, 1 in floor of the mouth and 1 in retromolar area. All tumors were composed by neoplastic adipocytes cells interlaced with normal salivary gland acinus cover it by a fibrous tissue capsule. Analyzes of literature showed that MiSG sialolipoma is most frequent in females over 60 years old, therefore and in conclusion this article assess different demographical profile of sialolipoma in respect to their topography.

Indications and procedures for direct immunofluorescence biopsies of the oral mucosa.

Quintessence Int 2015 Mar;46(3):247-53

A definitive diagnosis is crucial for management of any oral mucosal disease. Direct immunofluorescence (DIF) is a valuable diagnostic aid for immune-mediated blistering diseases and systemic connective tissue diseases of the skin and the mucosa. This paper gives an overview of the DIF biopsy technique for oral lesions and provides a background for the clinician to optimize the utilization of DIF biopsy. The key characteristic diagnostic findings of DIF of specific mucosal diseases are also discussed.

Inflammatory response to dental polishing and prophylaxis materials in rats.

J Int Acad Periodontol 2011 Oct;13(3):86-92

Department of Oral Diagnostic Sciences, School of Dental Medicine, State University of New York at Buffalo, Buffalo, NY 14214, USA.

Objective: To describe the tissue response to implanted polishing and prophylaxis materials using a rat model system.

Material And Methods: Two polishing pastes (diamond polishing paste and aluminum polishing paste), two prophylaxis materials (prophylaxis paste with fluoride and air polishing prophylaxis powder) and negative and positive controls were subcutaneously implanted in rats. Tissue specimens obtained after 2 days, 1, 4, 6 and 8 weeks after implantation were processed for routine hematoxylin and eosin staining and polarized light evaluation.

Results: Air polishing prophylaxis powder produced a mild inflammatory response. A more intense inflammation was elicited by diamond polishing paste, and the prophylaxis paste with fluoride elicited an even greater response. The aluminum polishing paste produced the most severe and persistent tissue response, which was of the granulomatous type.

Conclusions: This finding suggests that foreign body reaction should be considered in a gingivitis that does not respond to plaque control or does not represent a mucocutaneous lesion.

The challenges of defining oral cancer: analysis of an ontological approach.

Head Neck Pathol 2011 Dec 14;5(4):376-84. Epub 2011 Sep 14.

Department of Oral Diagnostic Sciences, School of Dental Medicine, University at Buffalo, 355 Squire Hall, 3435 Main Street, Buffalo, NY 14214, USA.

An important inconsistency currently exists in the literature on oral cancer. Reviewing this literature, one finds that the term oral cancer is defined and described with great variation. In a search in PubMed, at least 17 different terms were found for titles of papers reporting data on oral cancer. The variability of the terms used for designating anatomic regions and type of malignant neoplasms for reporting oral cancer has hampered the ability of researchers to effectively retrieve information concerning oral cancer. Therefore, it is sometimes extremely difficult to provide meaningful comparisons among various studies of oral cancer. Recently, a new ontological strategy that is rooted in consensus-based controlled vocabularies has been proposed to improve the consistency of data in dental research (Smith et al. in J Am Dent Assoc 141:1173-1175, 2010). In this paper, we analyzed the terminology dilemma on oral cancer and explained the current situation. We proposed a possible solution to the dilemma using an ontology-based approach. The advantages for applying this strategy are also discussed.

Gingival melanoacanthoma: case report and discussion of its clinical relevance.

Quintessence Int 2011 Mar;42(3):253-8

Department of Oral Diagnostic Sciences, School of Dental Medicine, State University of New York at Buffalo, Buffalo, NY 14214, USA.

Oral melanoacanthoma is an uncommon reactive condition that appears as a solitary pigmented lesion and is most often found on the buccal mucosa. For it to appear in the gingiva is extremely rare--only 11 cases are reported in the literature. This article presents a case of gingival melanoacanthoma and reviews the previously published cases. Because gingival melanoacanthoma shares clinical features with other pigmented lesions with diverse genesis, the differential diagnosis of a solitary pigmented lesion on the gingiva is also discussed.

Solitary fibrous tumor with entrapment of minor salivary gland tissue: an unusual presentation that requires exclusion of pleomorphic adenoma.

Head Neck Pathol 2011 Sep 19;5(3):314-20. Epub 2011 Mar 19.

Department of Oral Diagnostic Sciences, School of Dental Medicine, University at Buffalo, 3435 Main Street, 355 Squire Hall, Buffalo, NY 14214, USA.

We report two unusual cases of solitary fibrous tumor (SFT) of minor salivary glands that microscopically mimicked pleomorphic adenoma. One of these lesions presented in the retromolar region and the other in the buccal mucosa. The microscopic features of these two tumors and their intimate relationship with regional mucous minor salivary glands posed a diagnostic challenge. Awareness of the morphological diversity of SFT coupled to a judicious use of appropriate immunohistochemical probes should prove valuable to accurately segregate SFT from pleomorphic adenoma.

Estimation of individual neonatal survival using birthweight and gestational age: a way to improve neonatal care.

J Health Popul Nutr 2008 Mar;26(1):54-63

Department of Public Health, Faculty of Medicine, Pontificia Universidad Católica de Chile, Santiago, Chile.

The study was conducted to determine the combined effect of birthweight and gestational age at birth on neonatal mortality using individually-identified livebirths. Logistic regression was used for studying the interactive effect of birthweight and gestational age on the individual probability of neonatal death. All livebirths from Chile in 2000 were included in a linked file. Odds ratio models for birthweight and gestational age were developed for each sex. The probability of neonatal death by sex was presented using contour plots. The models were statistically significant, and odds ratios were different and non-linear for the effects of birthweight and gestational age. Contour plots of constant neonatal mortality according to birthweight and gestational age were presented; they were similar for each sex. A single graph for both sexes that estimates the survival potential of infants born too early or too small would improve neonatal care in developing countries.

Effects of a dairy product fortified with multiple micronutrients and omega-3 fatty acids on birth weight and gestation duration in pregnant Chilean women.

Public Health Nutr 2008 Jan 13;11(1):30-40. Epub 2007 Jun 13.

1Department of Public Health, School of Medicine, Faculty of Medicine, Pontificia Universidad Catolica de Chile, Marcoleta 434, Santiago, Chile.

Objective: To test the hypothesis that maternal food fortification with omega-3 fatty acids and multiple micronutrients increases birth weight and gestation duration, as primary outcomes.

Design: Non-blinded, randomised controlled study.

Setting: Pregnant women received powdered milk during their health check-ups at 19 antenatal clinics and delivered at two maternity hospitals in Santiago, Chile.

Subject: Pregnant women were assigned to receive regular powdered milk (n = 477) or a milk product fortified with multiple micronutrients and omega-3 fatty acids (n = 495).

Results: Intention-to-treat analysis showed that mean birth weight was higher in the intervention group than in controls (65.4 g difference, 95% confidence interval (CI) 5-126 g; P = 0.03) and the incidence of very preterm birth (0.80 just for mean birth weight and birth length in the on-treatment analysis; birth length in that analysis had a difference of 0.57 cm (95% CI 0.19-0.96 cm; P = 0.003).

Conclusions: The new intervention resulted in increased mean birth weight. Associations with gestation duration and most secondary outcomes need a larger sample size for confirmation.

[Height of pregnant women attended in the public and private health systems in Chile].

Rev Med Chil 2004 Dec;132(12):1483-8

Departamento de Salud Pública, Facultad de Medicina, Pontificia Universidad Católica de Chile, Santiago.

Background: Adult height has increased around the world, especially in developed countries, probably due to the improvement in life conditions.

Aim: To assess differences in women's height in two population samples of different socioeconomic status coming from the public and the private health system in Chile, and the influence of the year of birth on height.

Material And Methods: Data from 5,416 pregnant women attended in the public health system and 1,658 women attended in the private system, were analyzed. Among women attended in the private system, the association of maternal height with anthropometric indices of the newborn were also studied.

Results: Mean height difference in the two systems reached 3.78 cm. The correlation coefficient of maternal height and year of birth was significant although weak in the two health systems, but mean height differences between decades of birth were significant only in the public sector: 0.7 and 1 cm in each of the two most recent decades. Association of maternal height was significant although weak, with both weight and height at birth, controlling for newborn's sex.

Conclusions: Socioeconomic factors influence maternal height. Maternal height has an influence on fetal growth.

Multiple suppurative cystic lesions of the lips and buccal mucosa: a case of suppurative stomatitis glandularis.

Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2005 Feb;99(2):175-9

Department of Oral Diagnostic Sciences, School of Dental Medicine, State University of New York at Buffalo, Buffalo, New York 14214, USA.

Cheilitis glandularis (CG) is a rare inflammatory salivary gland disease that usually affects the lips. Although the etiology of CG is still unknown, it is believed to be a hereditary disease with an autosomal dominant pattern of inheritance. Three clinical presentations of CG are described in the literature: simple, superficial suppurative, and deep suppurative. A case of deep suppurative CG that extended to the buccal mucosa has been previously reported as suppurative stomatitis glandularis (SSG). Here we report a case of SSG in a 64-year-old white female with a history of bilateral renal transplants for adult polycystic kidney disease, who presented with painful swollen lips and bilateral buccal mucosal lesions. The diagnosis and management of the case is discussed. To the best of our knowledge, this is the second report of SSG, a rare condition affecting the minor salivary glands in the oral cavity.

A case of neurofibromatosis-Noonan syndrome with a central giant cell granuloma.

Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2004 Sep;98(3):316-20

School of Dentistry, University of Shaheed Beheshti, Tehran, Iran.

Neurofibromatosis Type 1 (NF1) is one of the most common autosomal dominant diseases affecting multiple systems including the vascular, skeletal, and central nervous system. Noonan syndrome (NS) is an autosomal dominant genetic disorder, associated with musculoskeletal and skin manifestations. Coexistence of central giant cell lesions in patients with both NS and NF1 were reported in the literature. Development of multiple central giant cell lesions in a patient with a Noonan syndrome has been referred to as Noonan-like syndrome. A few cases with features of NF1 and NS have been termed as NF1-NS. Here, we present a case of so-called NF-NS associated with a central giant cell lesion.
