A novel heterozygous frameshift mutation in the KRT6A gene responsible for an uncommon phenotype of pachyonychia congenita: One case report and review of literature.

Pachyonychia congenita is an uncommon autosomal dominant skin disorder characterized by hypertrophic nail dystrophy, palmoplantar keratoderma, oral leukokeratosis, and cutaneous cysts. And fissured tongue is rarely reported in patients with pachyonychia congenita. The disease is primarily associated with mutations in five keratin genes, namely KRT6A, KRT6B, KRT6C, KRT16 or KRT17. Herein we report a 9-year-old Chinese girl who has thickened nails, keratinized plaques, and fissured tongue since birth. To investigate the underlying genetic cause, whole-exome sequencing and Sanger sequencing were performed in this patient and her family members. We identified a candidate variant c.1460-2_1460del (p.S487Lfs*21) in the KRT6A gene (NM_005554.4) by whole-exome sequencing. Sanger sequencing revealed the absence of the mutation in both parents, indicating that it is a de novo variant. Thus, the novel heterozygous frameshift mutation c.1460-2_1460del (p.S487Lfs*21) within exon 9 of KRT6A was identified as the genetic cause of the patient. Our study identified a rare de novo heterozygous frameshift mutation in the KRT6A gene in a patient with pachyonychia congenita presenting fissured tongue. Our findings expand the KRT6A gene mutation spectrum of Pachyonychia congenita, and will contribute to the future genetic counseling and gene therapy for this disease.

Molecular phylogeny of Urvillea (Paullinieae, Sapindaceae) and its implications in stem vascular diversity.

BACKGROUND AND AIMS: The tribe Paullinieae has the highest diversity of vascular variants among the seed plants. The developmental diversity is better understood in the species-rich genera Paullinia and Serjania; however, the phylogeny and diversity of vascular variants in the smaller genera of Paullinieae remain understudied. Here we investigate the evolution of development of stem vasculatures in the small genus Urvillea. METHODS: We generate the first molecular phylogeny of Urvillea derived from 11 markers using a maximum likelihood and Bayesian approach. In combination with phylogenetic reconstruction, stochastic character mapping is used to assess evolutionary changes in stem ontogenies, determined from developmental anatomy of stems collected in the field or from herbarium and wood collections. KEY RESULTS: Urvillea is supported as a monophyletic group and sister to Serjania. There are five stem ontogenies in Urvillea, including typical growth and four different vascular variants. Most stem ontogenies initiate with lobed stems in primary growth. Lobed stems in secondary growth are ancestral in Urvillea, but this ontogeny was lost multiple times. A reversal to typical growth occurred in non-climbing species. Phloem wedges, fissured stems, and ectopic cambia each evolved once independently. Phloem wedges is an intermediate developmental stage in the formation of fissured stems, which is characterized by a continuous fragmentation of vascular tissues. Lobed stems may generate constriction zones and lobes may split or not. CONCLUSIONS: Urvillea is the third most diverse genus (after Serjania and Paullinia) with respect to the number of vascular variants within Paullinieae. One ontogeny (fissured stems) is exclusive to the genus. Differential cambial activity and ectopic cambia are the main ontogenetic processes generating stem diversity. The evolutionary history of vascular variants demonstrates the large developmental plasticity of the cambium in such a small genus and further demonstrates that complex anatomies have repeatedly evolved within Paullinieae lianas.

Differences in the morphological structure of the human tongue.

BACKGROUND: The tongue exhibits significant individual variability in terms of shape, color, and surface texture. Due to its location, it is easily accessible for medical examination, although often overlooked. This is due to the inadequate number of studies assessing the morphology of the tongue in the healthy population. Determining the range of normalcy allows for the definition of tongue pathology requiring further diagnostics. The aim of this study is to assess differences in the morphological structure of the tongue in healthy individuals based on existing literature. Morphological structure was evaluated in terms of volume, shape, color, coating, papillae, texture, and lingual tonsil. MATERIALS AND METHODS: PubMed and ResearchGate databases were included for a thorough analysis of morphological differences in tongue structure. RESULTS: Tongue volume stabilizes by the end of the second decade of life and is closely correlated with BMI. Among the shapes of the tongue, forms such as circular, ellipsoidal, hammer-shaped, in the shape of the letter U, V, or W can be distinguished, and the multitude of these terms results from the lack of a uniform classification. There is agreement regarding tongue color, with various shades of pink and white being the most commonly observed, while the presence of another color may indicate disease. The density and size of individual papillae depend on the region of the tongue, age, and the presence of systemic disease. Geographic tongue, hairy black tongue, and fissured tongue are states of papillae pathology. Fissuring of the tongue increases with age, and fissured tongue is more common in men. CONCLUSIONS: Differences in the morphological structure of the tongue provide significant information about the health status of each individual. It is necessary to be aware of the physiological changes occurring within the tongue for proper diagnosis.

Granulomatous gingival manifestation in Melkersson Rosenthal syndrome: a case report.

Melkersson-Rosenthal syndrome is a rare condition of unknown etiology. It is characterized by a classical triad of symptoms: relapsing facial and lip swelling, facial palsy and a fissured tongue. We report the case of a 29-year-old female patient who presented with the above-mentioned symptoms of Melkersson-Rosenthal syndrome. However, clinical examination revealed an exceptional manifestation, which is the gingival hyperplasia. The symptoms were partially managed with systemic steroids and surgical resection of gingival hyperplasia. The most significant finding to emerge from our case is that gingival enlargement can be identified as a rare clinical feature of the MRS disease, which is confirmed difficult to be managed.

Melkersson-Rosenthal Syndrome: A Case Report With a Bipolar Perspective.

Melkersson-Rosenthal syndrome (MRS) is a rare neuro-mucocutaneous condition that presents with orofacial swelling, facial paralysis, and a fissured tongue. These classic triad of symptoms, however, very rarely present simultaneously. The symptoms are often seen alone or in pairs and appear at any stage in life. Although the etiology of this condition is unknown, various contributing factors have been suggested including infections, immune deficiencies, stress, and genetic predispositions. We present a case of a 23-year-old female patient who has a longstanding history of MRS, anxiety, and depression, and who attempted to overdose on prescription medications due to suicidal ideations.

The Prevalence and Significance of Fissured Tongue in Kabul City Among Dental Patients.

Background: The tongue is known as the mirror of oral and general health. Some diseases may show signs in the tongue. Fissured is approximately an asymptomatic condition characterized by grooves and fissures of varying depth on the dorsal surface of the tongue. Epidemiologically, its prevalence is varied based on different factors, but most of them report 10-20%. Methods: In the department of oral medicine at Ali-Abad University Hospital of Kabul University of Medical Sciences, a cross-sectional study was conducted among 400 patients. This fissured tongue is first diagnosed based on clinical appearance (fissures) on each side of tongue. Meanwhile, the whole medical and dental histories were taken for the rest of the leading factors. Results: Out of 400 patients (124 males and 276 females) seen and checked, which 142 cases were fissured tongue [45 (31.7%) males and 97 (68.3%) females]. The fissures were found to be least in the >10 - 19-year age group, 23 (16.3%) and it was most prevalent in the 20 -39 age group, 73 (51.8%), followed by 40 -59, 35 (24.8%) and 60< age group, 10 (7.1%). The most prevalent type of pattern of fissures was found to be superficial, multiple and not connected fissures, 46.32% (33.3% males, 32.3% females), followed by superficial, multiple and connected fissures, 25.5% (26.7% males, 25% females), and whereas 6.4% of patients with (single and deep type of fissure) was the lowest prevalent type of fissured tongue. In our study, more than half of patients asymptomatic (51.6% females and 71.1% males), 17.9% complained from tongue dryness, 14.3% soreness, 6.4% halitosis, 1.4% tongue swelling and 2.1% had all the signs. Conclusion: The prevalence of fissured tongue was 35.5%. A significant difference between genders was reported with female predominance in all cases observed. The most prevalent age groups were 20-29 and 30-39 in both gender groups. Superficial, multiple, and not connected fissures 46.32% were the most common type of fissure.

Lactobacillus treatment as adjuvant for geographic tongue and fissured tongue with gastritis: case report.

Background: Geographic tongue and fissured tongue are both common oral mucous membrane diseases relatively. The treatment of this disease is typically causative therapy because of the unknown etiology, and other afflictions. Gastrointestinal disease is one of the factors that induce geographic tongue with a fissured tongue. As an adjuvant drug that can inhibit the growth of Helicobacter pylori, the most common pathogen of chronic gastritis, Lactobacillus is widely used in clinic. However, there are seldom studies about Lactobacillus used in the treatment of geographic tongue and fissured tongue. Therefore, this case we used typically causative therapy with Lactobacillus as adjuvant to treat patient with a geographic tongue and fissured tongue with gastrointestinal disease and explore the effectiveness for further application. Case Description: A 33-year-old female patient presented with a geographic tongue and fissured tongue with dysgeusia. At the first visit, there were smooth red lesions on the back of the tongue with the hyperplasia of the surrounding filiform papilla. The cracks in the middle of the tongue had a crack of about 2.5 cm long and 0.8 cm deep, and 5-6 light cracks on the tip of the tongue. The patient reported a history of chronic gastritis for 1 year, often with soft stool and gastroesophageal reflux disease. We administered drug treatment, including sodium bicarbonate tablets, Kangfuxin solution, compound chlorhexidine solution, and stomatitis spray. In addition, we suggested the patient use a yogurt machine to make and drink fresh yogurt with Lactobacillus as adjuvant everyday day and suggested a daily regimen of a light diet with no stimulating food, regular work, and sufficient rest. Ten days after the first visit, the symptoms were obviously alleviated. Twenty days after the initial diagnosis, the geographic tongue lesions had disappeared and the cracks had basically healed. The patient reported that the gastric symptoms had improved, and there was no soft stool or stomach discomfort. Conclusions: This study used Lactobacillus as the adjuvant with typically causative therapy in the treatment of geographic tongue and fissured tongue.

The PTEN hamartoma tumor syndrome: how oral clinicians may save lives.

INTRODUCTION: Patients with the PTEN hamartoma tumor syndrome (PHTS) have an 81%-90% cumulative lifetime risk of developing cancer. Around 90% of these patients have recognizable oral features. Receiving a diagnosis may save these patients' lives. This is the first presentation of a family with the PHTS diagnosis with focus on the oral and periodontal findings and treatments. CASE PRESENTATION: All three children (one son and two daughters) inherited the same heterozygous variant in the PTEN gene from their father. Gingival overgrowth was observed in all patients in addition to macrocephaly. Other findings included fissured tongue, high arched palate, papules, and trichilemmomas. The father had experienced severe tooth loss. Surgery was performed to treat the gingival overgrowth and periodontal pockets; however, the treatment was characterized by multiple recurrences of the overgrowth. CONCLUSIONS: Oral changes, macrocephaly, tumors, and/or a family history of benign or malignant lesions are important features that oral clinicians should be aware of for a possible PHTS diagnosis. Patients suspected of having PHTS should be referred to a medical practitioner, specifically a geneticist, for further diagnostic investigations. The periodontal problems seemed to be difficult to control for these patients. They will likely need an active and frequent maintenance therapy to control the persistent inflammation and gingival overgrowth. In addition, they need a thorough monitoring for benign or malignant changes in the orofacial regions. Why are these cases new information? Oral features are found in 90% of the cases with the PHTS diagnosis. The periodontal findings showed a persistent recurrence of gingival overgrowth with a strong probability of serious periodontal diseases. What are the keys to successful management of these cases? A suspicion of a PHTS diagnosis with a referral to a medical practitioner, specifically a geneticist, for complete workup may help save these patients' lives. Close monitoring during maintenance therapy with re-treatment as needed to prevent further periodontal complications. Continued monitoring and treatment throughout the patient's lifetime for development of recurrent or new, benign or malignant lesions at relevant sites. What are the primary limitations to success in these cases? A failure to identify the PHTS syndrome with the accompanying oral and periodontal complications. Complications may lead to a delay in appropriate treatment. Inability to control the persistent gingival overgrowth and a deteriorating periodontal condition. A failure to discover benign and malignant lesions in the orofacial region.

Melkersson-Rosenthal syndrome: a classical case report / Síndrome de Melkersson-Rosenthal: relato de caso clássico

ABSTRACT The Melkersson-Rosenthal syndrome constitutes a rare manifestation characterized by a triad of signs and symptoms: recurrent orofacial edema, fissured tongue, and recurrent facial paralysis. The difficulty in diagnosing Melkersson-Rosenthal syndrome is that orofacial edema is common to various diseases besides the lack of awareness of the syndrome by health professionals and the frequent metachronous manifestation of its symptomatology. The aim of this report is to present a classical case of Melkersson-Rosenthal syndrome and its clinical and therapeutic approach. A patient who sought for assistance at the Stomatology Clinic presented a synchronous manifestation of the triad: a left lip and cheek nonpitting edema accompanied by facial paralysis on the same side and fissured tongue. Melkersson-Rosenthal syndrome was diagnosed due to the presence of the triad of signs and symptoms after initially ruling out Crohn's disease, Sarcoidosis, and tuberculosis due to a lack of intestinal or respiratory complaints and absence of other clinical evidence. The treatment administered was steroids, the most common treatment with a satisfied prognosis we found in the literature for Melkersson-Rosenthal syndrome patients. We recommend its implementation intralesional injections of betamethasone dipropionate as after four infiltrations the edema subsided by 80% with no further relapses within one-year follow-up.

RESUMO A síndrome de Melkersson-Rosenthal constitui uma manifestação rara caracterizada por uma tríade de sinais e sintomas: edema orofacial recorrente, língua fissurada e paralisia facial recorrente. A dificuldade no diagnóstico da síndrome de Melkersson-Rosenthal é que o edema orofacial é comum a diversas doenças, além do desconhecimento da síndrome pelos profissionais de saúde e da frequente manifestação metacrônica de sua sintomatologia. O objetivo deste relato é apresentar um caso clássico de síndrome de Melkersson-Rosenthal e sua abordagem clínica e terapêutica. Paciente procurou atendimento no Ambulatório de Estomatologia apresentando manifestação sincrônica da tríade: edema não depressível em lábio e bochecha esquerdos acompanhado de paralisia facial do mesmo lado e língua fissurada. A síndrome de Melkersson-Rosenthal foi diagnosticada devido à presença da tríade de sinais e sintomas após a exclusão inicial de doença de Crohn, sarcoidose e tuberculose por ausência de queixas intestinais ou respiratórias e ausência de outras evidências clínicas. O tratamento administrado foi o esteroide, sendo o tratamento mais comum com prognóstico satisfatório que encontramos na literatura para pacientes com SRM. Recomendamos a aplicação de injeções intralesionais de dipropionato de betametasona, pois após quatro infiltrações o edema cedeu em 80% sem novas recidivas em um ano de seguimento.

Prevalence of Oral Normal Variance in Healthy Elderly Patients: A Descriptive Study on Oral Pseudo-Lesions

Abstract Introduction The aging process in the elderly can change the condition of the oral cavity, regarding both clinical appearance and function. The oral mucosa becomes more susceptible to mechanical damage and irritant agents. Any changes in the oral mucosa, including normal variance, should be examined. This is especially true for the elderly, to improve oral health and prevent any abnormalities. Objective To describe the prevalence of oral normal variance in healthy elderly patients. Methods An observational descriptive study with a cross-sectional design with total sampling conducted from March to April 2020. Results Among the 117 elderly patients who participated in this study, 58 were described as healthy without any comorbidities. From those subjects, there were 117 cases of normal variance in the oral mucosa. The three most prevalent issues were fissured tongue (93.1%), coated tongue (58.62%), and crenated tongue (27.59%). Conclusion Fissured tongue is a normal variance of the oral mucosa that is commonly found in healthy elderly patients.

Melkersson-Rosenthal Syndrome in a 38-Year-Old Female Patient: A Rare Case With Complete Triad.

Melkersson-Rosenthal syndrome (MRS) is an uncommon neuro-mucocutaneous disease, clinically characterized by a triad of recurrent facial palsy, orofacial swelling, and fissured tongue. This report presents the case of a 38-year-old female diagnosed with MRS based on its three clinical features. A corticosteroid (1 mg/kg/day of oral prednisolone) was prescribed for a week, and then tapered off over two weeks by gradually lowering the dose. Regular annual long-term follow-ups were requested to monitor the disease activity.

Oral Lesions in Patients With Psoriasis: Prevalence and Association With Its Clinical and Epidemiological Characteristics. / Manifestaciones orales en pacientes con psoriasis. Prevalencia y asociación con sus características clínicas y epidemiológicas.

BACKGROUND AND OBJECTIVE: Psoriasis is a multisystem disease associated with an increased prevalence of oral lesions. The aim of this study was to determine the prevalence of oral lesions in patients with psoriasis and examine associations with clinical and patient characteristics. MATERIAL AND METHODS: We conducted a cross-sectional study of patients with psoriasis and healthy controls seen between December 2019 and February 2020. We recorded biometric data, comorbidities associated with psoriasis, oral examination findings, and clinical characteristics of psoriasis. RESULTS: We studied 100 patients with psoriasis and 100 controls. Oral lesions were more common in the psoriasis group (74% vs 46%, P<.001). The most common lesions were fissured tongue (39% vs 16%, P<.001) and periodontitis (28% vs 16%, P=.04). Geographic tongue was uncommon in both the study and the control group (4% vs 2%, P=.68). In the psoriasis group, patients with fissured tongue had a higher prevalence of cardiovascular disease (23.1% vs 4.9%), diabetes mellitus (28.2% vs 8.2%), and psoriatic arthritis (15.4% vs 1.6%) than those without this condition. Periodontitis was also associated with a higher prevalence of cardiovascular disease (28.6% vs 5.6%). Type of psoriasis, location, and time since onset were not significantly associated with oral lesions. Patients with oral lesions, however, had more severe disease (Psoriasis Area Severity Index [PASI], 3.9 vs 2.4; P=.05). Mean PASI was also higher in patients with fissured tongue (4.7 vs. 2.7, P=.03) and periodontitis (5.1 vs. 2.9, P=.04). CONCLUSIONS: The prevalence of oral lesions, especially fissured tongue and periodontitis, is higher in patients with psoriasis than in healthy controls. Oral lesions were associated with more severe psoriasis and a higher prevalence of associated comorbidities. We recommend examining the oral cavity of patients with psoriasis, especially those with more severe disease and comorbidities, irrespective of type of psoriasis, location, or time since onset.

Manifestaciones orales en pacientes con psoriasis. Prevalencia y asociación con sus características clínicas y epidemiológicas / Oral Lesions in Patients With Psoriasis: Prevalence and Association With Its Clinical and Epidemiological Characteristics

Antecedentes y objetivo: La psoriasis es una enfermedad con una gran implicación sistémica en la que se ha descrito una mayor prevalencia de alteraciones de la mucosa oral. El objetivo del estudio fue determinar la prevalencia de alteraciones orales en pacientes con psoriasis y su asociación con las características clínicas y epidemiológicas de la enfermedad. Material y métodos: Se realizó un estudio transversal, incluyendo pacientes con psoriasis y voluntarios sanos entre diciembre de 2019 y febrero de 2020. Se recogieron datos biométricos, comorbilidades asociadas y alteraciones orales detectadas en la exploración física. Además, en los pacientes con psoriasis se registraron las características clínicas de la enfermedad. Resultados: Se incluyeron 100 pacientes con psoriasis y 100 controles. Los pacientes con psoriasis presentaron una mayor prevalencia de alteraciones de la mucosa oral respecto al grupo control (74% frente a 46%, p<0,001), destacando una mayor prevalencia de lengua fisurada (LF) (39% frente a 16%, p<0,001) y periodontitis (28% frente a 16%, p=0,04). La lengua geográfica resultó poco frecuente en ambos grupos (4% frente a 2%, p=0,68). Dentro del grupo con psoriasis, los pacientes con LF presentaron mayor prevalencia de enfermedad cardiovascular (23,1% frente a 4,9%), diabetes mellitus (28,2% frente a 8,2%) y artritis psoriásica (15,4% frente a 1,6%) que aquellos sin LF. Los pacientes con periodontitis presentaron también mayor frecuencia de enfermedad cardiovascular (28,6% frente a 5,6%). La forma, la localización y el tiempo de evolución de la psoriasis no se relacionaron con más alteraciones orales. Sin embargo, los pacientes con alteraciones orales presentaron valores medios de la escala PASI (índice de severidad del área de psoriasis) más elevados (3,9 frente a 2,4, p=0,05). Los pacientes con LF presentaron un PASI más elevado que aquellos sin LF (4,7 frente a 2,7, p=0,03) (AU)

Classification of fissured tongue images using deep neural networks.

BACKGROUND: Tongue inspection is vital in traditional Chinese medicine. Fissured tongue is an important feature in tongue diagnosis, and primarily corresponds to three Chinese medicine syndromes: syndrome-related hotness, blood deficiency, and insufficiency of the spleen. Diagnosis of the syndrome is significantly affected by the experience of clinicians, and it is difficult for young doctors to perform accurate diagnoses. OBJECTIVE: The syndrome not only depends on the local features based on fissured regions but also on the global features of the whole tongue; therefore, a syndrome diagnosis framework combining the global and local features of a fissured tongue image was developed in the present study to achieve a quantitative and objective diagnosis. METHODS: First, we detected the fissured region of a tongue image using a single-shot multibox detector. Second, we extracted the global and local features from a whole tongue image and a fissured region using TongueNet (developed in-house). Third, we developed a classifier to determine the final syndrome. RESULTS: Based on an experiment involving 721 fissured tongue images, we discovered that TongueNet affords better feature extraction. The accuracy of TongueNet was 4% (p< 0.05) and 3% (p< 0.05) higher than that of InceptionV3 and ResNet18, respectively, for whole tongue images. Meanwhile, at local fissured regions, the accuracy of TongueNet was 3% (p< 0.05) higher than that of InceptionV3 and equal to that of ResNet18. Finally, the fusion features outperformed the global and local features with a 78% accuracy. CONCLUSIONS: Our findings indicate that TongueNet designed with batch normalization and dropout is more suitable for uncomplicated images than InceptionV3 and ResNet18. In addition, compared with the global features, the fusion features supplement the detailed information of the fissures and improve classification accuracy.

Risk factors associated with tongue lesions: a propensity score-matched case-control study

Background: to analyse the potential risk factors of tongue lesions, comparing the results with a control group. Material and Methods: An observational, case-control study was designed. The study included a case group comprising 336 patients with tongue lesions and 336 sex and age-matched controls. We recorded tobacco/alcohol habits, presence of dentures, allergies, medical conditions, and medications. Statistical analysis was performed via logistic regression models to estimate the odds ratio (OR) adjusted for gender, age, tobacco, and alcohol using propensity score-matching analysis (PSM). Results: According to the final PSM model, patients with tongue lesions were more likely to suffer from allergies (OR 2.13; 1.27-3.66) or medical conditions (OR 2.14; 1.19-3.85), and more likely to take medication (OR 1.99; 1.11-3.57). Elderly individuals were more prone to hairy tongue (OR 3.82; 1.53-10.47). Smoking was associated with coated tongue (OR 2.05; 1.12-3.63), hairy tongue (OR 3.77; 1.52-9.22) and median rhomboid glossitis (OR 40.49; 5.84-860.43). Allergic individuals were more likely to exhibit sublingual varices (OR 1.73; 1.02-2.88). Medical conditions increased the chances of having coated tongue (OR 2.44; 1.36-4.64) or crenated tongue (OR 2.70; 1.42-5.30). Arterial hypertension was associated with median rhomboid glossitis (OR 5.85; 1.08-34.18). Individuals on medication showed a higher risk of fissured tongue (OR 1.87; 1.20-2.94) and varices (OR 2.42; 1.58-3.80). Agents acting on the alimentary tract and metabolism increased the probability of fissured tongue (OR 2.31; 1.42-3.79). Conclusions: As far as we are aware, this is the first study on lingual pathology to include a PSM analysis. The results suggest that a history of allergies, the presence of medical conditions, and the use of medication are associated with increased probability of tongue lesions. The analysis of diseases and medications by subgroups requires studies matched by habits with larger sample sizes, in order to corroborate our observations.(AU)

Alergias alimentarias en pacientes con glositis migratoria benigna / Food allergies in patients with benign migratory glossitis

Introducción: la glositis migratoria benigna, también conocida como lengua geográfica, es una variante normal, que presenta zonas superficiales circulares. Según la literatura revisada, dentro de sus causas figuran los procesos alérgicos, en los que están las alergias alimentarias. Se decidió realizar esta investigación para determinar la prevalencia de las alergias alimentarias frecuentes en estos pacientes mediante pruebas cutáneas. Materiales y métodos: se realizó un estudio descriptivo, longitudinal y prospectivo. La muestra estuvo compuesta por 27 pacientes en el período de enero hasta agosto de 2018 en portadores de glositis migratoria benigna, a los cuales se les realizaron pruebas alérgicas de tipo cutáneas para la determinación de alergias alimentarias. Resultados: el 59,3 % fue mujer y el antecedente alérgico más frecuente fue la rinitis alérgica. El antecedente de alergia alimentaria más frecuente fue los lácteos. Respecto a los resultados de las pruebas para la leche y los mariscos, estas dieron positivas en la mayoría de los pacientes, seguidos por el pescado, los huevos y los frutos secos. La prevalencia de positividad para por lo menos una prueba fue de 85,2%. Discusión: actualmente no existe suficiente literatura que hable sobre las posibles etiologías de la glositis migratoria benigna. Dentro de los antecedentes alérgicos, la rinitis alérgica fue la más frecuente, seguida de la alergia alimentaria. Hasta ahora existen pocas investigaciones que estudien esta prevalencia de alergias alimentarias en los pacientes de forma específica. Conclusión: la lengua geográfica no tiene factor epidemiológico predominante. El antecedente alérgico puede ser un factor predisponente, la alergia alimentaria puede ser desencadenante de la presentación de la lengua geográfica.

Introduction: The benign migratory glossitis, also known as geographic tongue, is a normal variant, which presents circular or irregular depapillated superficial areas. According to the literature reviewed, its causes include allergic processes, among these are food allergies. It was decided to carry out this investigation to determine the prevalence of frequent food allergies in these patients using skin tests. Materials and methods: A descriptive, longitudinal, prospective study was carried out. The sample consisted of 27 patients in the period January-August 2018, carriers of geographic tongue who underwent skin-type allergic tests to determine food allergies. Results: 59.3% were women without statistically significant predominance, the most frequent allergic history was allergic rhinitis. The most frequent history of food allergy was to dairy. Regarding the results of the tests for milk and shellfish, they were positive in 55.6%, followed by fish 14.8%, eggs and nuts with 11.1% respectively. The prevalence of positivity for at least one test was 85.2% with a statistically significant predominance over the negative result. Discussion: There is currently not enough literature that discusses the possible etiologies of benign migratory glossitis. Within the allergic history, allergic rhinitis was the most frequent, followed by food allergy. Until now there are few investigations that study this prevalence of food allergies in patients in a specific way. Conclusion: Geographic tongue does not have a predominant epidemiological factor, an allergic history can be a predisposing factor, food allergy can be a trigger for presentation of geographic language.

COVID and the Risky Immigrant Workplace: How Declining Employment Standards Socialized Risk and Made the COVID-19 Pandemic Worse.

This article investigates the impacts of the COVID-19 pandemic in NYC as they were concentrated on immigrant workers and their communities, studying one group of immigrant workers, namely taxi drivers. Based on two years of ethnographic research with the New York Taxi Workers Alliance, a union of 24,000 taxi and app-based drivers in NYC, conducted before and during the pandemic, as well as formal interviews and an original survey of 1,002 union members, my research shows how drivers' precarious existence in the work-citizenship nexus informed their experiences of sustaining their families during the pandemic. COVID highlighted how the welfare state's increasing privatization of risk, the fissuring of the workplace, and the rise in employment precarity have generated an immigrant underclass. This manifested in immigrant drivers experiencing the pandemic through the lens of specific uncertainties-health, economic, bureaucratic, and immigration-that shaped their unequal access to pandemic support. This process in turn produced a boomerang effect, as immigrant drivers' weaker connection to state and social institutions made it harder to contain the virus in their communities, a development which ultimately puts society writ large at greater risk. This article advances our knowledge of precious employment by introducing the concept of uncertainties to explain the socio-cultural aspects of how crises of social reproduction are generated. It also extends our understanding of the decline of the welfare and regulatory state by showing how this process interacts with immigrant status.
