Congenital malformations in ruminants and its surgical management: a retrospective study of Sokoto veterinary clinic, Nigeria

Background:Congenital defects, abnormalities of structures or functions present at birth, maybe as a result ofgenetic or environmental factors or both and in most cases; the exact etiology is not clear but can occur in all animals. These abnormalities are responsible for slowing down of genetic progress and economic loss for the breeders, due to the death of animals.Methods:Available record of cases presented to Aliyu JedoVeterinary Clinic,Sokoto from December 2015 to 2019 was used to investigate congenital malformation in ruminants based on species and sex. Surgery was carried out in all the cases with local anaesthesia (infiltration technique) using lignocaine. Surgical procedures carriedout were rectopexy (atresia ani), gingivectomy (gingival fibromatosis), superficial keratectomy and temporary tarssorhaphy (dermoid cyst), casting and physiotherapy (contracted tendons). Results:A total of 47 congenital malformations; atresia ani 22 (46.8%), gingival fibromatosis 18(38.3%), dermoid cyst 6(12.8%), and contracted tendon 1(2.1%) were reviewed in the study.The ovine species had the highest incidence of cases load recorded 23(48.93%) followed by bovine 17(36.17%) and then caprine species7(14.89%). The incidence of all malformations was higher in males (68.1%) than in females (31.9%). All cases were attempted surgically with success in all the procedures.Conclusions:It can be concluded that male ruminants have the highest prevalence of congenital malformation. Congenital malformations are more frequently seen in ovine and least seen in caprine. Atresia ani appeared to be the most commonly reported cases

Idiopathic gingival fibromatosis: a case report and literature review / 口腔疾病防治

Objective @#To explore the etiology, clinical manifestations, diagnosis, differential diagnosis and treatment of idiopathic gingival fibromatosis, and to provide references for clinical diagnosis and treatment.@*Methods @#The clinical data and related literatures of a case of idiopathicgingival fibroma that occurred in the oral cavity were retrospectively analyzed. @*Results @#Total periodontal treatment was performed for the patient, and the gingival morphology was improved after periodontal surgery in the anterior region. Idiopathic gingival fibromatosis is a rare disease characterized by gingival tissue hyperplasia. The etiology and pathogenesis are unknown. The disease can occur in young children. Generally, it occurs after the permanent teeth erupt, and it manifests as extensive gingival hyperplasia, which can affect the entire gingival margin, gingival papilla and attached gingival, and can even reach the membrane-gingival junction. The pathological changes include thickening of the spinous layer of the gingival epithelium, significant increases in the epithelial styloid process, increases in the connective tissue volume, and filling with large collagen fiber bundles and a large number of fibroblasts. The blood vessels are relatively small, and inflammation is not obvious. Clinically, this disease needs to be distinguished from drug-induced gingival hyperplasia and chronic gingivitis with hyperplasia as the main manifestation. At present, the treatment of idiopathic gingival fibromatosis is mainly gingival angioplasty. The disease easily relapses after surgery. The recurrence rate is related to the quality of oral hygiene. After recurrence, it can be treated again.@*Conclusion@# Idiopathic gingival fibromatosis is relatively rare, and the diagnosis mainly depends on the history of inquiry, clinical manifestations and pathological examination. The treatment is mainly surgical resection, and future research should focus on finding a more effective treatment.

The study of pathogenic mechanism in hereditary gingival fibromatosis / 实用医学杂志

Objective To determine the role of B cell specific moloney leukemia virus insert site 1 (Bmil) in hereditary gingival fibromatosis (HGF). Methods The HE staining was used to analyze the HGF and normal groups. The protein and mRNA of the Bmil, PCNA and caspase-3 in 2 groups were detected by immunohistochemistry and PCR, respectively. Results In HGF group, the gingival epithelial was incrassation, epithelial spikes was elongation, connective tissue was rich in fibroblast and collagen fibers, aless blood vessels and mild inflammatory hyperplasia. Bmil expression was higher (P < 0.05) and caspase-3 expression was lower (P < 0.05) in HGF group than in normal group. There was no difference of PCNA expression in the 2 groups (P> 0.05).Conclusion The Bmil might have a role in the pathogenesis of HGF by decreasing caspase-3 and caspase-3 mRNA.

Exploring the Genetic Basis of Periodontal Diseases–A Review.

The periodontal disease is initiated by microbial plaque, which accumulates in the gingival crevice & induces an inflammatory response. This inflammation leads to chronic gingivitis, which is reversible & may later progress as periodontitis, by destruction of bone & other tooth-supporting structures. Although present in most of the population, the risk for periodontal disease is not uniform for all individuals. About 10-15% of the population develops severe destruction of the periodontal structures leading to early loss of the tooth. This inflammatory response leading to periodontal destruction is assumed to have a genetic basis. It is now recognized that poor oral hygiene alone cannot account for severe destructive periodontal disease, that certain individuals are at relatively high risk of periodontal destruction and that the risk is partly under genetic control. The microbial causation of the inflammatory periodontal disease is well established. There are however other elements that influence the inflammatory and immune response both locally and systemically. These include systemic disease such as diabetes and environmental factors such as smoking and possibly stress. The effectiveness of an individual’s immune response may influence the extent of periodontal destruction. The role of genetic factors in the causation of peridontitis is worthy of in depth discussion.

Fibromatosis Gingival Idiopática Unilateral: Reporte de un Caso con Cuatro Años de Seguimiento / Unilateral Idiopathic Gingival Fibromatosis: Case Report With Four-Year Follow-Up

La fibromatosis gingival es una enfermedad rara que se caracteriza por aumento del tejido gingival por proliferación fibrosa, es de crecimiento lento, cubriendo en algunos casos la totalidad de los dientes comprometidos. Esta nosología comprende un grupo heterogéneo de patologías de causas no determinadas. El objetivo de este trabajo es presentar un caso clínico de una paciente de 13 años con FGI Unilateral, su diagnóstico, tratamiento y seguimiento durante cuatro años. Presenta al examen clínico intraoral, agrandamiento anormal de su encía tanto superior como inferior, afectando solamente los hemiarcos del sector izquierdo. A la palpación es indolora y de consistencia fibrosa. No se encontraron factores locales que justifiquen dicho aumento. El examen físico elimina la posibilidad de otras patologías asociadas, no refiriendo recibir medicaciones inmunosupresivas, antiepilépticos o antihipertensivas. No tiene antecedentes familiares. La paciente fue sometida a extirpación quirúrgica del tejido hiperplasiado y el material obtenido enviado a estudio histopatológico. Después del tratamiento quirúrgico y una buena higiene oral con exámenes de control efectuados durante cuatro años no se observó recurrencia. A pesar de ser una patología poco frecuente el odontólogo debe conocer la fisiopatología y comprender que el manejo de ésta enfermedad es a través de un equipo multidisciplinario. El diagnóstico precoz y el tratamiento oportuno logran la recuperación psicológica, estética y funcional de los pacientes.

Gingival fibromatosis is a rare disease characterized by progressive enlargement of the gingiva caused by an increase in submucosal connective tissue. The enlargement may potentially cover the exposed tooth surfaces. Idiopathic gingival fibromatosis (IGF) is a heterogeneous group of disorders with no definite cause. The aim of this study is to present a 13-year-old female patient with unusual clinical forms of Unilateral FGI with a complete analysis of the features of the clinical diagnosis, treatment and follow-up for four years. Intraoral examination revealed severe gingival overgrowth involving both the upper arch and the lower arch, affecting on the left side. The right side of the mouth was unaffected. There was no significant pain. The lesion was diffuse, firm and fibrotic. Her medical and family history was also non-contributory. The patient was not receiving any antiepileptic, antihypertensive, or immunosuppressive medications that could contribute to the gingival enlargement. Histopathological examination showed hyperparakeratinized stratified squamous epithelium, presence of a thickened acanthotic epithelium and focal hyperplasia. Underlying connective tissue stroma was collagenous with numerous lymphoplasmacytic infiltrate. Unusual findings include the presence of calcified particles. Bevel gingivectomy was taken to remove gingival overgrowth. This case is thus a rare and atypical presentation of gingival fibromatosis. The patient was advised to maintain good oral hygiene to minimize the effect of inflammation on fibroblasts. In our case, even after four years of follow-up, no recurrence of gingival overgrowth was observed. Unilateral IGF is a relatively rare condition with poorly understood etiopathogenesis and recurrence rates. The cases should be treated with a multidisciplinary management. Treatment appreciably improved the patient's psychological, aesthetics and masticatory competence.

Unilateral Gingival Fibromatosis: a case report / Fibromatose Gengival Unilateral: um relato de caso

The gingival fibromatosis is a slow and progressive benign proliferation, which affects the gingival tissues. It may present a genetic inheritance and association with some syndromes. There are conservative and radical treatments, ranging from hygiene care to bloc resection of the affected bone. This case scenario is a 07 year-old child, who presented a nodular unilateral hyperplastic lesion in the right mandible, with sessile base and approximately 5 cm in its largest diameter. The patient presented difficulty of lip closure and slight swelling in the right area of the face. The tomographic image showed infiltration in buccal and lingual cortical of right mandible and tooth displacement. After lesion removal, the histopathologic diagnosis of fibromatosis was confirmed, with no relapse after 20 months of follow-up.

A Fibromatose Gengival é uma proliferação benigna, lenta e progressiva, que afeta os tecidos gengivais. Pode apresentar herança genética e associação à uma série de síndromes. Existem tratamentos conservadores e radicais, desde cuidados com higiene à ressecção em bloco do tecido ósseo afetado. Este é o caso clínico de uma criança, que apresentou lesão hiperplásica unilateral em mandíbula, com deslocamento dentário. Após remoção, o diagnóstico de hiperplasia gengival foi confirmado e não há recidiva da lesão até o momento.

A rare case of isolated idiopathic gingival fibromatosis.

Idiopathic gingival fibromatosis (IGF) is a rare condition. It is genetically heterogeneous and is usually part of a syndrome or, rarely, an isolated disorder. This study presents a rare case of 13 year old boy who was diagnosed with isolated IGF. This diagnosis has been based on clinical examination and after ruling out family, drug, and medical histories. External bevel gingivectomy has been done to remove excess gingival tissues. Excised tissue has been examined histologically. The patient has been followed up for a period of two and half years. No recurrence has been observed.

Hereditary gingival fibromatosis - a case report and management using a novel surgical technique

Introduction: Hereditary gingival fibromatosis (HGF) is a rare condition presenting varied degrees of gingival enlargement. HGF can present as an isolated entity or as part of a syndrome. Current literatures report a defect in the Son of sevenless-1 gene (SOS-1) on chromosome 2p21-p22 (HGF1) as a possible cause of this condition. Case report: A case of a 16-year-old female is reported who presented generalized extensive gingival overgrowth, involving the maxillary and mandibular arches covering almost two thirds to three quarters of all teeth. Diagnosis of HGF was substantiated by the patient's clinical features, family history and histopathological examination. Treatment was excision of the gingival tissue by a modified gingivectomy technique with both manual instrumentation and electrosurgery. The postoperative course was uneventful and the patient's aesthetic concerns were addressed. Post-surgical follow-up after 18 months demonstrated no recurrence. Conclusion: Hereditary gingival fibromatosis stands apart from other gingival enlargements in the varied treatment options available and the nature of recurrence post treatment. There is no consensus among authors related to the mode of treatment. Here, in this present case report we highlight a novel surgical technique to deal with the extensive nature of enlargement seen in HGF cases.

Gingival fibromatosis with hemi-osseous hyperplasia of jaws, focal maxillary viral papillomatosis of gingiva, fissured tongue and congenitally missing anterior teeth: A case report and surgical management of a new syndrome.

Gingival fibromatosis is characterized by fibrotic enlargement of the gingiva that can occur as inherited or sporadic form. Inherited form can be an isolated trait or as a component of a syndrome. This article reports a 35 year old male patient affected by gingival fibromatosis associated with hemiosseous hyperplasia of mandible, maxilla, and zygoma on the right side, viral papillomatosis of maxillary anterior gingiva, fissured tongue and congenitally missing anterior teeth. The patient was subjected to phase I and phase II periodontal therapy. There was no evidence of recurrence of the enlargement after one year but the papillomatosis recurred. Gingival fibromatosis has been reported to be associated with various other abnormalities but not with those described in our case. This observation raises the possibility that the coexistence of these entities in our case may represent a new syndrome.

Minichromosome maintenance 2 and 5 expressions are increased in the epithelium of hereditary gingival fibromatosis associated with dental abnormalities

INTRODUCTION: Gingiva fibromatosis is a relatively rare condition characterized by diffuse enlargement of the gingiva, which is caused by expansion and accumulation of the connective tissue. OBJECTIVE: The aim of the present study was to investigate proliferative and apoptotic biomarker expression in normal gingiva and two forms of gingival fibromatosis. METHODS: Archived tissue specimens of hereditary gingival fibromatosis, gingival fibromatosis and dental abnormality syndrome and normal gingiva were subject to morphological analysis and immunohistochemical staining. The results were analyzed statistically. RESULTS: Proteins associated with proliferation were found in the nuclei of epithelial cells from the basal and suprabasal layers, whereas apoptotic proteins were detected in the cytoplasm of the upper layers of the epithelium. Increased expressions of minichromosome maintenance proteins 2 and 5 were observed in the gingival fibromatosis and dental abnormality syndrome samples. In contrast, geminin expression was higher in normal gingiva samples. No difference in the expression of apoptotic proteins was observed among the groups. CONCLUSION: Our findings support a role for augmented proliferation of epithelial cells within the overgrown tissues associated with gingival fibromatosis or dental abnormality syndrome. However, our data suggest that different biological mechanisms may account for the pathogenesis of different types of gingival fibromatosis.

A 14 year old female patient suffered from unusual gingival enlargement, more on the left side along with generalized aggressive periodontitis. The enlarged gingiva covered more than two-thirds of the clinical crowns. Marked inflammatory hyperplasia of epithelium and connective tissue of the gingiva was observed histopathologically. Perioscan test was performed, the results of which were negative. The diagnosis of Idiopathic gingival fibromatosis with aggressive periodontitis was made. Conventional periodontal therapy was performed followed by excision of the enlargement using gingivectomy procedure.

Gingival Fibromatosis with Chronic Periodontitis – A Rare Case Report

Gingival fibromatosis is frequently an isolated condition of little consequence apart from a cosmetic problem and occasional associations with uncommon syndromes. This case report of a 38 year old female patient describes the gingival enlargement associated with chronic periodontitis. The enlargement extended beyond the middle thirds of the clinical crowns of the teeth. It was associated with generalized mobility, pocket formation and bone loss. The patient also complained of bleeding gums and difficulty in speech and mastication. This is the first case report of gingival fibromatosis associated with chronic periodontitis.

Fibromatose gengival hereditária: identificação e tratamento / Hereditary Gingival Fibromatosis: Identification and Treatment

A Fibromatose Gengival Hereditária (FGH) é descrita como uma condição bucal rara, clinicamente manifestada por um crescimento lento, progressivo, difuso e benigno dos tecidos gengivais. Alguns autores defendem a hipótese de o aumento gengival ser transmitido por um gene autossômico dominante, porém outros mostram que a FGH parece ser transmitida por um gene autossômico recessivo, em que pessoas não afetadas transmitemessa anormalidade a seus descendentes. O modo de transmissão hereditária parece ser autossômicodominante, relacionado ao cromossomo 2p21. A FGH pode se manifestar, de um modo geral, em duas situações diferentes: a primeira, quando o crescimento exagerado da gengiva constitui a única alteração patológica clinicamente observável, e a segunda, quando a fibromatose gengival é uma das alterações que se manifesta associada a outras patologias sistêmicas, como o retardo mental, a epilepsia, a hipertricose e a surdez progressiva. Através de uma revisão da literatura, este trabalho buscou elucidar todas as suas características, objetivando facilitar sua identificação, tratamento e controle

Hereditary gingival fibromatosis (HGF) is described as a rare oral condition, clinically manifested by a slow, progressive and benign enlargement of gingival tissues. Some authors support the hypothesis that HGF is transmitted by an autosomal dominant gene, while others think that HGF seems to be transmitted by an autosomal recessive gene, when non-affected subjects transmit this abnormality to their descendants. Thehereditary transmission mode seems to be an autosomal dominant inheritance related to the chromosome 2p21. In general, HGF can be observed in two different clinical situations: the first, when the exaggerated growth of the gingiva constitutes the only clinical pathological alteration observable and the second, when gingival fibromatosis associates with other systemic conditions, such as mental retardation, epilepsy, hypertrichosis and gradual deafness. The aim of this study was to review the literature on hereditary gingival fibromatosis and describe its characteristics to enable the diagnosis, treatment and control of this disease

Avaliação estrutural e diagnóstica de três lesões fibrosas da cavidade bucal / A structural and diagnostic evaluation of three oral fibrous lesions

O objetivo do presente trabalho é analisar os componentes celulares e de fibras do tecido conjuntivo nas hiperplasias inflamatórias (HI), nos fibromas (F) e na fibromatose gengival hereditária (FGH), além de investigar a imunocompetência e efetuar análises moleculares de pacientes com FGH. Para atingir os objetivos foram desenvolvidos 4 artigos, com diferentes metodologias e universos amostrais. No 1° artigo, pretendeu-se estabelecer critérios microscópicos validos para diferenciar F e HI. Foram avaliadas em microscópio óptico 136 lesões coradas pela Hematoxilina-eosina (HE) e pelo Tricrômico de Masson quanta às características microscópicas. Os resultados mostraram que uma área central de fibras colágenas dispostas de forma enovelada e mais densa, circundada por uma camada de fibras dispostas de forma paralela são características dos F, enquanto a presença de hiperplasia epitelial, infiltrado inflamatório e fibras colágenas organizadas de forma paralela são características das HI. Tais resultados motivaram o 2° artigo, no qual estudamos 18 lesões de F e 13 de HI, que foram preparadas histologicamente e coradas pelo picrosírius red e pelo direct blue para avaliação quantitativa das fibras colágenas e de fibras do sistema elástico, respectivamente, em microscopia a laser confocal. Os resultados confirmaram a disposição estrutural das fibras colágenas observada no 1° artigo, além de apontarem diferenças nas áreas ocupadas pelas fibras colágenas em todas as regiões estudadas. A fim de proceder a uma avaliação dos componentes fibroso e celular das 3 lesões fibrosas, foi desenvolvido o 3° artigo. Especimes das 3 lesões foram estudados em microscopia ótica, a fim de avaliar suas populações de fibroblastos e de células inflamatórias e os seguintes componentes fibrosos do tecido conjuntivo...

The objective of this study was to analyze the cellular and fibrous components of connective tissue in inflammatory hyperplasia (IH), oral fibroma (OF) and hereditary gingival fibromatosis (HGF), and to investigate the immuno competence and to perform molecular analysis in HGF patients. To achieve the goals were developed 4 articles, with different methodologies and sample universes. In the 1st article, we intended to establish microscopic criteria to differentiate F and IH. The microscopic characteristics of the lesions (n=136) stained by hematoxylin-eosin (HE) and Masson trichrome were evaluated in an optical microscope. The results showed that a central area of wound collagen fibers and arranged in a higher density, surrounded by a layer of parallel fibers are characteristic of F, while the presence of epithelial hyperplasia, inflammatory infiltrate and parallel collagen fibers are characteristics of HI. These results led the 2nd article, which studied 18 F and 13 and IH, histologically prepared and stained by picrosirius red and direct blue for the direct quantitative assessment of collagen fibers and elastic fibers of the system, respectively, in the confocal laser microscope. The results confirmed the structural arrangement of collagen fibers found in Article 1, and indicate differences in the areas of collagen fibers in all regions studied. In order to evaluate the cellular and fibrous components of the 3 fibrous lesions, was developed the 3rd article. Specimens of the 3 lesions were studied in optical microscopy, to assess their populations of fibroblasts and inflammatory cells and the following components of fibrous connective tissue: collagen fibers, elastic fiber system, reticular fibers and oxytalan fibers. The results showed different arrangement and concentration of collagen fibers in the 3 lesions and a higher concentration of reticular fibers in HGF. The analysis of...
