Oral manifestations of hematologic and nutritional diseases. Otolaryngol Clin North Am. 2011;44:183-203, vii. [PMID: 21093629 DOI: 10.1016/j.otc.2010.09.007]

The Bloody Crossroads: Interactions between Periodontitis and Hematologic Diseases

Periodontitis is a common oral condition that can have a significant impact on the overall health of the body. In recent years, attention has been paid to potential relationships between periodontitis and various hematological disorders. This publication aims to present information available in the literature on this relationship, focusing on examples of red blood cell disorders (such as aplastic anemia and sickle cell anemia) and white blood cell disorders (such as cyclic neutropenia, maladaptive trained immunity, clonal hematopoiesis, leukemia, and multiple myeloma). Understanding these associations can help physicians and dentists better diagnose, monitor, and treat patients associated with both groups of conditions, highlighting the need for interdisciplinary care for patients with oral disorders and hematologic diseases.

Cheilitis: A cross-sectional study-multiple factors involved in the aetiology and clinical features

OBJECTIVE

Since the aetiologies of cheilitis are broad and overlapping, the purpose of this cross-sectional clinical study was to examine the multiple factors involved in aetiology and the disease's clinical features.

SUBJECTS AND METHODS

We analysed cheilitis prevalence, demography, clinical features, patients' habits, psychological stress, systemic diseases, vitamin B9, B12 and iron serum levels and allergy test results in a total of 130 subjects with cheilitis, plus 22 healthy subjects.

RESULTS

The most common cheilitis types were: cheilitis simplex and eczematous cheilitis (28.5%); herpetic cheilitis (16.9%); and exfoliative and angular cheilitis (7.7%). Concerning bad habits, there was a significant association/connection between self-reported saliva at the corners of the mouth and angular cheilitis, and between lip licking/biting and exfoliative cheilitis. Common associated conditions were skin diseases (56.5%) and atopy (84%). Vitamin B9 and B12 serum and iron values were mostly within the normal reference range. The patients suffering from herpetic cheilitis had significantly higher psychological/mental stress levels than the control group.

CONCLUSION

To our knowledge, this is the first study of cheilitis patients that has simultaneously analysed aetiological factors, characteristics of the disease and diagnostic parameters.

Evaluation of biochemical variables in patients with recurrent aphthous stomatitis

PURPOSE

We investigated the effects of various biochemical agents on the etiopathogenesis of recurrent aphthous stomatitis (RAS).

METHODS

We enrolled 70 RAS patients and 70 healthy volunteers. Peripheral venous blood samples were collected. We performed complete blood counts, then measured the levels of ferritin, vitamin B12, iron, magnesium, phosphorus, calcium, thyroid-stimulating hormone, T3, T4, and 25-hydroxy D3.

RESULTS

The groups did not differ in terms of age (p = 0.912) or sex (p = 0.612). The levels of ferritin and 25-hydroxy vitamin D were significantly lower in RAS patients (both p ˂ 0.05).

CONCLUSION

Vitamin D and/or ferritin deficiency may induce RAS. Measurements of vitamin D and ferritin may assist diagnosis and follow-up.

Factors Participating in the Occurrence of Inflammation of the Lips (Cheilitis) and Perioral Skin

Lip inflammation may manifest as mainly reversible cheilitis, mainly irreversible, or cheilitis connected to dermatoses or systemic diseases. Therefore, knowing a patient’s medical history is important, especially whether their lip lesions are temporary, recurrent, or persistent. Sometimes temporary contributing factors, such as climate and weather conditions, can be identified and avoided—exposure to extreme weather conditions (e.g., dry, hot, or windy climates) may cause or trigger lip inflammation. Emotional and psychological stress are also mentioned in the etiology of some lip inflammations (e.g., exfoliative cheilitis) and may be associated with nervous habits such as lip licking. To better manage cheilitis, it is also helpful to look for potential concomitant comorbidities and the presence of related diseases/conditions. Some forms of cheilitis accompany dermatologic or systemic diseases (lichen, pemphigus or pemphigoid, erythema multiforme, lupus, angioedema, xerostomia, etc.) that should be uncovered. Occasionally, lip lesions are persistent and involve histological changes: actinic cheilitis, granulomatous cheilitis, glandular cheilitis, and plasmacellular cheilitis. Perioral skin inflammation with simultaneous perioral dermatitis can have various causes: the use of corticosteroids and cosmetics, dysfunction of the skin’s epidermal barrier, a contact reaction to allergens or irritants (e.g., toothpaste, dental fillings), microorganisms (e.g., Demodex spp., Candida albicans, fusiform bacteria), hormonal changes, or an atopic predisposition. Epidermal barrier dysfunction can worsen perioral dermatitis lesions and can also be related to secondary vitamin or mineral deficiencies (e.g., zinc deficiency), occlusive emollient use, sunscreen use, or excessive exposure to environmental factors such as heat, wind, and ultraviolet light. Current trends in research are uncovering valuable information concerning the skin microbiome and disruption of the epidermal barrier of persons suffering from perioral dermatitis. Ultimately, an effective approach to patient management must take all these factors and new research into account.

Association between different dietary patterns and eating disorders and periodontal diseases

Periodontal diseases is a highly prevalent chronic condition regulated by the host immune response to pathogenic bacterial colonization on the teeth surfaces. Nutrition is a critical component in the modulation of the immune system, hence the importance of a balanced diet. With the understanding of how dietary intake composition affects various health outcomes, nutrient diversity has been reported as a modifiable risk factor for periodontal disease. Eating disorders and different dietary patterns can be associated with periodontal diseases. In this sense, balanced and healthy nutrition plays a major role in maintaining the symbiosis between oral microbiota and periodontal health. Therefore, this review seeks to report the associations found in the literature between high- or low-fat/sodium/sugar, eating disorders and periodontal diseases. It was found that some dietary patterns such as high carbohydrate/sugar, high fat, and low fiber intake may be associated with periodontal disease. In addition, the presence of eating disorders can negatively impact patients' oral health and it is related to the development of several complications, including periodontal diseases. In both situations, nutritional and vitamin deficiencies can aggravate the periodontal condition. However, the relationship between periodontal disease, dietary patterns, and eating disorders still needs more scientific support to be well established, mainly in the sense of pointing out a protective relationship between both.

Prevalence and Characteristic of Oral Mucosa Lesions

(1) Background: Oral mucosa lesions (OMLs) are diagnosed worldwide in any population, age or gender, but in varied prevalence. OMLs can be found in each site of the oral mucosa; for some of them, it is characteristic to have a bilateral/symmetrical or unilateral/nonsymmetrical mucosal manifestation. The knowledge about its prevalence in varied populations can be useful from a clinical point of view. The aim of this study is to assess the prevalence of OMLs in patients attending outpatient dental clinic; (2) Retrospective analysis of 2747 patients’ oral cavity medical charts, who referred to oral pathology outpatient clinic. The type of diagnosed oral lesion, sex and age were evaluated. p ≤ 0.05 was considered statistically significant; (3) Results: In this study, the overall prevalence of oral mucosal lesions was found to be higher in older than younger patients. In our study, the age median was the highest in patients with xerostomia, burning mouth syndrome, angular cheilitis and oral candidiasis. The youngest median age was observed in patients with aphthae, mucocele and gingival enlargement. The higher OMLs frequency was related with the female gender. (4) It is important for clinicians to be familiar not only with distinctive features, which sometimes may not be clear, but also with linking the occurrence of OMLs with the gender and age.

Spontaneous retrobulbar hemorrhage in the setting of warfarin therapy and latent scurvy diagnosis

We present a case of spontaneous nontraumatic retrobulbar hemorrhage associated with anti-coagulation therapy and a new diagnosis of scurvy. A 68-year-old male on chronic anti-coagulation therapy presented with a retrobulbar hemorrhage requiring urgent canthotomy and cantholysis. Despite the absence of a supratherapeutic INR and normal clotting factors, the patient continued to have spontaneous hemorrhages within the orbit and elsewhere. Workup revealed a severe vitamin C deficiency consistent with scurvy. Further investigation of dietary history demonstrated an avoidance of all citrus fruit upon starting warfarin due to misunderstanding in medication counseling on avoidance of grapefruit. With repletion of vitamin C and further medication counseling, the patient had no further episodes of spontaneous hemorrhage.

Recognition and management of vitamin B12 deficiency: Report of four cases with oral manifestations

Vitamins are organic compounds present in low concentrations in food, performing vital and specific cell metabolism functions. Vitamin B12 is essential for red blood cell formation in the bone marrow and its deficiency is caused, mainly, by gastrointestinal malabsorption. In addition to systemic manifestations, oral signs and symptoms have also been associated to this condition such as glossitis, papillary atrophy, painful erythema areas, burning sensation, dysgeusia, lingual paresthesia and itching. This study aims to report four cases of oral manifestations caused by vitamin B12 deficiency. All patients presented oral mucosa lesions. Vitamin B12 deficiency was diagnosed based in clinical characteristics and complementary exams. Oral supplementation for vitamin B12 deficiency was conducted/realized in three patients, while one patient was treated with parenteral doses. All of them showed partial or total remission of the signs and symptoms.

Crohn's disease initially presenting with oral manifestations and managed with ustekinumab: A case report

Oral Crohn's disease (OCD) refers to the spectrum of oral manifestations seen in Crohn`s disease (CD) patients and could precede other signs of the disease elsewhere, which requires dental practitioners to be vigilant for oral mucosal changes that may accompany such systemic disorders. Classical treatment modalities are based on the use of corticosteroids, immune-modulators and more recently, biologics. Ustekinumab is a novel agent from this last group that has shown efficacy in a limited number of case reports. A case of a debilitating CD presenting initially with oral manifestations and ultimately managed with ustekinumab is reported.

The Impact of DNA Methylation on IL6 mRNA Levels in Hematinic Deficiency and Atopy-Associated Recurrent Aphthous Stomatitis Patients

Objective

To investigate the DNA methylation using pyrosequencing and its effects on the upregulation of IL6 mRNA in patients with recurrent aphthous stomatitis (RAS) in connection with hematinic deficiency and atopy. Material and Methods. This cross-sectional study was conducted at Dr. Hasan Sadikin Hospital, Bandung, from January–March 2019 and was approved by the Health Research Ethics Committee of Universitas Padjadjaran (Ethics No. 990/UN6.KEP/EC/2018). Furthermore, the subjects had RAS ulcers with a history of at least twice a year along with atopy and dietary imbalance with no history of recurrent intraoral herpes or any systemic diseases. This study was performed on 23 RAS patients and 21 healthy subjects, and the sampling was carried out consecutively. The blood samples were collected from all the subjects, and then, the DNA and RNA were extracted from the peripheral blood mononuclear cells (PBMCs). Consequently, the bisulfite-modified DNA was used to confirm the methylation status of the IL6 gene promoter through the pyrosequencing method. The methylation levels of the IL6 promoter were assessed by a reverse transcriptase-polymerase chain reaction technique. The gene expression of RAS and the control group was analyzed by the 2^−ΔΔC_T method. The statistical analysis using the Mann–Whitney U test was conducted to evaluate IL6 mRNA levels and DNA methylation with p value <0.05 considered to be statistically significant.

Result

The IL6 mRNA levels were approximately 1.88-fold in RAS patients, and there was a significant relationship between the expression of the IL6 gene and the increased risk of RAS (p < 0.001). It was reported that four out of six sites in the cytosine phosphate guanine (CpG) island IL6 promoter had a lower degree of methylation, and two other sites in patients with RAS had greater methylation compared with control, but not statistically significant.

Conclusion

This study showed the upregulation of IL6 mRNA levels in RAS patients compared to control. DNA methylation in the present study is at sites 566–658, whereas the location of the IL6 promoter is at sites 1–1684. Thus, it would be necessary conducting some research at other CpG sites of IL6 promoter islands to determine the status of DNA methylation.

Oral manifestations of inflammatory bowel disease: the neglected piece of the puzzle

Inflammatory bowel disease (IBD) is a chronic relapsing remitting autoimmune disease including Crohn's disease and ulcerative colitis. IBD is associated with various extra-intestinal manifestations including oral manifestation. To date, only limited studies addressing the characteristics of the oral manifestations are available. The aim of the present review is to report the oral manifestations and their characteristics in IBD. A Medline/PubMed and Embase databases search were conducted and all relevant studies were extracted and analyzed. Overall, the oral manifestations in IBD were mostly associated with Crohn's disease rather than Ulcerative colitis where their prevalence ranged from 8 to 50%. Specific lesions for Crohn's disease include mucosal tags, cobblestoning and deep linear ulcerations with vertical fissures, while for ulcerative colitis, pyostomatisis vegetans was more disease specific. Notably, most of the oral manifestations were unrelated to disease activity, however more data are needed to accurately assess this correlation. Oral manifestations among IBD patients are not uncommon as Crohn's disease account for most of them. More data are warranted to precisely characterize their prevalence and association to intestinal activity.

The profile of hematinic deficiencies in patients with oral lichen planus: a case-control study

Background

Oral lichen planus (OLP) is a relatively common mucocutaneous disorder, and its causative factors and pathogenesis are not fully understood. Existing studies on the association between hematinic deficiencies and OLP are limited and inconsistent. The aim of this study was to assess the hematinic deficiencies in a cohort of OLP patients and evaluate the correlation between hematinic deficiencies and OLP.

Methods

A total of 236 OLP patients and 226 age-and-gender-matched healthy controls were enrolled in this study. The levels of hemoglobin (Hb), serum folate, vitamin B12 and ferritin were measured and compared between OLP patients and healthy controls. An REU (reticular/hyperkeratotic, erosive/erythematous, ulcerative) scoring system was adopted and compared between the OLP patients with and without hematinic deficiencies. The correlation between hematinic deficiencies and OLP was analyzed.

Results

The frequencies of serum ferritin and vitamin B12 deficiency in OLP patients were both significantly higher than those of the healthy controls. According to gender and age, the profiles of hematinic deficiencies in OLP patients were significantly different. As for the REU score, no significant difference existed between OLP patients with and without hematinic deficiencies. Both serum ferritin deficiency and serum vitamin B12 deficiency were significantly correlated with OLP.

Conclusions

The present study suggested a significant association between hematinic deficiencies and OLP. Iron, folate, and vitamin B12 levels in OLP patients should be monitored routinely. Further studies are warranted to explore the interactions between OLP and hematinic deficiencies.

A Personalised Dietary Approach-A Way Forward to Manage Nutrient Deficiency, Effects of the Western Diet, and Food Intolerances in Inflammatory Bowel Disease

This review discusses the personalised dietary approach with respect to inflammatory bowel disease (IBD). It identifies gene–nutrient interactions associated with the nutritional deficiencies that people with IBD commonly experience, and the role of the Western diet in influencing these. It also discusses food intolerances and how particular genotypes can affect these. It is well established that with respect to food there is no “one size fits all” diet for those with IBD. Gene–nutrient interactions may help explain this variability in response to food that is associated with IBD. Nutrigenomic research, which examines the effects of food and its constituents on gene expression, shows that—like a number of pharmaceutical products—food can have beneficial effects or have adverse (side) effects depending on a person’s genotype. Pharmacogenetic research is identifying gene variants with adverse reactions to drugs, and this is modifying clinical practice and allowing individualised treatment. Nutrigenomic research could enable individualised treatment in persons with IBD and enable more accurate tailoring of food intake, to avoid exacerbating malnutrition and to counter some of the adverse effects of the Western diet. It may also help to establish the dietary pattern that is most protective against IBD.

Oral Manifestation as the Main Sign of an Advanced Stage Acute Promyelocytic Leukemia

Acute myeloid leukemia is an aggressive malignant neoplasm occurring mainly in elderly, with the median age of 65 years. Oral manifestations, mainly spontaneous bleeding, are a common finding in acute myelocytic leukemia and may represent the initial evidence of the disease. This report describes a case of a 47-year-old man with a one-month history of spontaneous oral bleeding. The patient had already been consulted by two professionals but he remained undiagnosed. The physical examination revealed paleness, fever, epistaxis and ecchymoses in the oral mucosa. The complete blood count revealed anemia, severe thrombocytopenia and leukocytosis with blasts predominance, reinforcing the diagnosis hypothesis of an acute leukemia. The patient was immediately referred to the Hospital and despite having received a quick intervention, he died 3 days after the admission due to diffuse pulmonary alveolar hemorrhage. According to the peripheral blood immunophenotyping the diagnosis of hypogranular variant of acute promyelocytic leukemia was established. The delay in the diagnosis may have influenced the unfavorable outcome. Early diagnosis and management are indispensable for survival of leukemia patients. In this way, dentists may be responsible for an early detection of oral manifestations of leukemia and for a fast referral to an adequate professional.

Oral Changes in Patients with Sickle Cell Anemia of Dentistry Interest

AbstractSickle cell anemia is determined by the presence of S hemoglobin in homozygous, autosomal recessive and characterized by the presence of red cells with abnormal shape (sickle shape). The clinical manifestations may vary from one individual to another, and it may appear in the first year of the patient’s life, which emphasizes the importance of early diagnosis as the main measure of positive effect in the care of people with the disease. The aim of this study was to conduct a review of the literature on oral alterations of dental surgeon’s interest in patients with sickle cell anemia. The search for the key words “sickle cell anemia” and “oral manifestations” was carried out in the Scientific Electronic Library Online database (SciELO), linked to the Virtual Health Library (VHL). The oral manifestations described in the literature were: paleness of the oral mucosa, smooth, bleached and despapilated tongue or jaundice, delays in dental eruption, periodontal disease, hypo mineralization of the enamel, pulp calcifications, hypercementose, aseptic pulp necrosis, mandibular nerve neuropathy, osteomyelitis and orofacial pain. People with the disease may also exhibit mouth ulcers, particularly in the gums. Anemia causes a high degree of suffering for patients, who deserve special attention from all the multiprofessional team that attends them. Therefore, it is important that the dental surgeon understands and knows the symptoms of the disease, as well as its implications for oral health, as well as the best treatment. The adoption of constant care, with prevention measures in oral care and health, is important to inhibit the occurrence of dental infections.Keywords: Anemia, Sickle Cell. Dental Care. Oral Manifestations.ResumoA anemia falciforme é determinada pela presença da hemoglobina S em homozigose, de caráter autossômico recessivo e caracterizada pela presença de células vermelhas com formato anormal (forma de foice). As manifestações clínicas variam de acordo com o indivíduo e ao longo do percurso da doença, pois pode surgir no primeiro ano de vida do paciente, o que enfatiza a importância do diagnóstico precoce como principal medida de efeito positivo na assistência às pessoas com a doença. O objetivo deste trabalho foi realizar uma revisão de literatura sobre as alterações bucais de interesse do cirurgião-dentista em pacientes com anemia falciforme. A busca pelas palavras chaves “anemia falciforme” e “manifestações bucais” foi realizada na base de dados Scientific Electronic Library Online - SciELO, vinculada à Biblioteca Virtual em Saúde - BVS.

Hematinic deficiencies in patients with recurrent aphthous stomatitis: variations by gender and age

Background

The aim of this study was to evaluate the association between hematinic deficiencies and recurrent aphthous stomatitis (RAS).

Material and Methods

517 RAS patients and 187 healthy controls were enrolled in the present study. Hematinic deficiencies, including serum ferritin, folic acid, and vitamin B12 deficiencies were assessed for each participant. Gender and age were taken into account and the collected data were statistically analysed.

Results

Compared with the healthy controls, a significantly higher overall frequency of hematinic deficiencies was found in RAS patients (p<0.001). When gender and age were taken into account, significant differences in hematinic deficiencies were observed among RAS patients. Serum ferritin deficiency was much more common in young and middle-aged female RAS patients (age<60). Serum folate deficiency and serum vitamin B12 deficiency were both much more common in the young adult group of male RAS patients (21–40 years of age). Logistic regression analysis revealed that both gender and age have significant correlation with the presence of hematinic deficiencies in the RAS patients.

Conclusions

Significant variations in hematinic deficiencies were demonstrated in RAS patients across different genders and age groups. We suggest that further studies on the hematinic deficiencies of RAS patients should take into account the gender and age of participants.

Key words:Recurrent aphthous stomatitis, hematinic deficiencies, gender, age.

Regular oral screening and vigilance: can it be a potential lifesaver?

Acute myeloid leukemia (AML) is a malignant neoplasm of myeloid series defined by the presence of immature blast cells (>30%) in peripheral circulation. Oral manifestations are the potential indicators of systemic health and disease. Oral cavity is the frequently and early involved sites in AML. Gingival overgrowth due to leukemia is one such condition encountered by periodontists. Hence, understanding, identifying, and correlating oral manifestations with systemic diseases are the ultimate responsibility of every dental clinician because of its lethal and unpredictable course. In the present case, we are discussing an undiagnosed case of AML who presented to us with oral complaints.

Dental Manifestations of Pediatric Bone Disorders

PURPOSE OF REVIEW

Several bone disorders affecting the skeleton often are manifest in the maxillofacial region. This review presents the most common bone disorders in children and their dental-oral manifestations: fibrous dysplasia, Paget's disease, osteogenesis imperfecta, renal osteodystrophy, hypophosphatasia, and osteoporosis. The specific intraoral characteristics will reviewed in detail.

RECENT FINDINGS

Recent studies confirmed the close relationship between the mandible and the maxilla with the most prevalent systemic bone disorders in children. This review will help practitioners to integrate the oral health into the systemic health and improve the multidisciplinary approach of pediatric patients between medicine and dentistry.

Diseases of the lips

Heath care providers should be comfortable with normal as well as pathologic findings in the lips, because the lips are highly visible and may display clinical manifestations of local, as well as systemic inflammatory, allergic, irritant, and neoplastic alterations. Fortunately, the lips are easily accessible. The evaluation should include a careful history and physical examination, including visual inspection, as well as palpation of the lips and an examination of associated cervical, submandibular, and submental nodes. Pathologic and microscopic studies, as well as a review of medications, allergies, and habits, may further highlight possible etiologies. Many lip conditions, including premalignant changes, are relatively easy to treat, when the abnormalities are detected early; however, advanced disease and malignancies are challenging for both the patient and clinician. Treatment should be focused on eliminating potential irritants or allergens and treatment of the primary dermatosis. In this paper we review physiologic variants as well as pathologic conditions of the lips.

Measuring salivary blood: A potential in vivo assay to quantify platelet transfusion efficacy

Salivary blood is known to increase in patients with intraoral mucosal bleeding. Mucosal bleeding is a frequent sequelae of thrombocytopenia, which is typically managed with platelet transfusion. Within the past few years, multiple different types of platelet products have become available, each with potential differences in efficacy. Typically, platelet transfusion efficacy is demonstrated by the increase in platelet count after transfusion. However this approach is complicated by the fact that activated platelets tend to produce lower post-transfusion platelet counts, but may be more efficacious in a bleeding patient. Intraoral blood levels, measured by salivary transferrin, urine dipstick hemoglobin or another method, could be used as an in vivo assay to monitor a patient's response to platelet transfusion and compare different types of platelet products.

Ethnopharmacological Approaches for Therapy of Jaundice: Part I

Jaundice is a very common symptom especially in the developing countries. It is associated with several hepatic diseases which are still major causes of death. There are many different approaches to jaundice treatment and the growing number of ethnomedicinal studies shows the plant pharmacology as very promising direction. Many medicinal plants are used for the treatment of jaundice, however a comprehensive review on this subject has not been published. The use of medicinal plants in drug discovery is highly emphasized (based on their traditional and safe uses in different folk medicine systems from ancient times). Many sophisticated analytical techniques are emerging in the pharmaceutical field to validate and discover new biologically active chemical entities derived from plants. Here, we aim to classify and categorize medicinal plants relevant for the treatment of jaundice according to their origin, geographical location, and usage. Our search included various databases like Pubmed, ScienceDirect, Google Scholar. Keywords and phrases used for these searches included: "jaundice," "hyperbilirubinemia," "serum glutamate," "bilirubin," "Ayurveda." The first part of the review focuses on the variety of medicinal plant used for the treatment of jaundice (a total of 207 medicinal plants). In the second part, possible mechanisms of action of biologically active secondary metabolites of plants from five families for jaundice treatment are discussed.

Hypophosphatasia: diagnosis and clinical signs - a dental surgeon perspective

BACKGROUND

Hypophosphatasia (HPP) is a rare inherited metabolic disease in which mutations in the ALPL gene (encoding tissue-nonspecific alkaline phosphatase) result in varying degrees of enzyme deficiency. HPP manifests in a spectrum of symptoms, including early primary tooth loss (root intact) and alveolar bone mineralisation defects.

OBJECTIVE

To provide an overview of HPP for dental professionals to help recognise and differentially diagnose patients for appropriate referral to a specialist team.

METHODS

A non-systematic review of publications on HPP was performed.

RESULTS

Different forms of HPP are described, along with characteristic symptoms and laboratory findings. Diagnosis is challenging due to the rareness and variable presentation of symptoms. Low alkaline phosphatase levels are a signature of HPP, but reference ranges vary according to gender and age. Key features are defined and management strategies discussed, focusing on enzyme replacement therapy. Finally, a patient registry aimed at better defining the prevalence of HPP and raising awareness is described.

CONCLUSIONS

HPP is a rare disease with a wide spectrum of manifestations, with orodental symptoms featuring prominently in the natural history. Dental professionals may be positioned at the beginning of the diagnostic pathway; thus, recognition of HPP features for timely referral and optimal disease management is important.

Oral pathology in inflammatory bowel disease

The incidence of inflammatory bowel diseases (IBD) - Crohn’s disease (CD) and ulcerative colitis (UC) - has been increasing on a global scale, and progressively, more gastroenterologists will be included in the diagnosis and treatment of IBD. Although IBD primarily affects the intestinal tract, extraintestinal manifestations of the disease are often apparent, including in the oral cavity, especially in CD. Specific oral manifestations in patients with CD are as follows: indurate mucosal tags, cobblestoning and mucogingivitis, deep linear ulcerations and lip swelling with vertical fissures. The most common non-specific manifestations, such as aphthous stomatitis and angular cheilitis, occur in both diseases, while pyostomatitis vegetans is more pronounced in patients with UC. Non-specific lesions in the oral cavity can also be the result of malnutrition and drugs. Malnutrition, followed by anemia and mineral and vitamin deficiency, affects the oral cavity and teeth. Furthermore, all of the drug classes that are applied to the treatment of inflammatory bowel diseases can lead to alterations in the oral cavity due to the direct toxic effects of the drugs on oral tissues, as well as indirect immunosuppressive effects with a risk of developing opportunistic infections or bone marrow suppression. There is a higher occurrence of malignant diseases in patients with IBD, which is related to the disease itself and to the IBD-related therapy with a possible oral pathology. Treatment of oral lesions includes treatment of the alterations in the oral cavity according to the etiology together with treatment of the primary intestinal disease, which requires adequate knowledge and a strong cooperation between gastroenterologists and specialists in oral medicine.

[Cheilitis: Diagnosis and treatment]

The whole examination of oral cavity, other mucosae and skin is required when managing a cheilitis. Irritants (climatic, mechanical, caustic agents...) constitute the main aetiological factors of cheilitis. Allergic contact cheilitis should be investigated with a detailed anamnesis in order to search any causative agent in contact with the oral mucosae. Patch testing is required to confirm the diagnosis of delayed hypersensivity. Chronic actinic cheilitis occurs mostly in middle-aged, fair-skinned men. It is a potentially malignant condition that requires biopsies to exclude severe dysplasia or carcinoma. Angular cheilitis can occur spontaneously but is frequently related with several precipitating factors, such as systemic immune suppression, local irritation and moisture, fungal and/or bacterial infection. Cheilitis can also be seen in various systemic conditions such as lichen planus, lupus, atopic dermatitis and nutritional deficiencies. Erosive and crusty cheilitis and bullous erosive stomatitis are the main oral features of erythema multiforme and Stevens-Johnson syndrome. Granulomatous macrocheilitis (cheilitis granulomatosa) presents with intermittent or permanent lip swelling. It should be confirmed by a biopsy. It can be either isolated (Miescher macrocheilitis) or associated with various systemic conditions.
