Trauma-induced exostosis of multiple suture lines causing partial bilateral nasolacrimal duct obstruction in a 7-year-old Thoroughbred mare.

A definitive diagnosis of extensive suture line exostoses affecting the nasofrontal, nasolacrimal, nasomaxillary, frontolacrimal, lacrimozygomatic and lacrimomaxillary suture lines in a 7-year-old Thoroughbred mare with chronic bilateral epiphora and facial deformation was achieved using standing computed tomography (CT) examinations. Positive contrast dacryocystorhinography using CT revealed partial bilateral obstruction of the nasolacrimal ducts. Minimally displaced depression fractures of the right nasal bone, the right maxillary bone and right frontal bone were also demonstrated. The cosmetic appearance of the periosteal reaction associated with the suture line exostosis and epiphora significantly improved within 3 months of diagnosis and treatment.

Exostose palatina bilateral em bebê / Exostosis palatina bilateral en bebé / Bilateral palatal exostosis in an infant

RESUMO Introdução: As exostoses são definidas como protuberâncias ósseas localizadas, de caráter benigno, sendo uma rara patologia em bebês. Objetivo: Relatar um caso de exostose palatina bilateral em um bebê melanoderma do sexo feminino de 1 ano e 4 meses de idade. Relato de caso: A criança compareceu a Clínica Escola de Odontopediatria, acompanhada de sua mãe, para avaliação odontológica. Durante a anamnese, o responsável queixou-se de atraso na irrupção dos dentes decíduos e presença de protuberância na arcada superior, sem sintomatologia dolorosa. Foi relatado que três membros da família também apresentavam essa mesma alteração na maxila ou mandíbula, possivelmente sugerindo um componente genético. Ao exame clínico intrabucal, verificou-se um aumento de volume ósseo bilateral plano localizado na maxila, na região lingual das tuberosidades palatinas, recoberto por mucosa bucal normal. A superfície era rígida à palpação e com bordas claramente definidas. O componente genético foi associado ao aspecto clínico da lesão, bem como o sexo e a etnia. O diagnóstico estabelecido foi exostose palatina bilateral. A biópsia e o tratamento ativo para remoção da patologia não se justificaram devido à pouca idade da criança, ausência de sintomatologia dolorosa e de interferências na alimentação, deglutição ou outra função bucal. A paciente foi acompanhada periodicamente e apresentou sequência de irrupção dos dentes decíduos normal. Conclusão: Embora a exostose palatina apresente baixa prevalência em crianças, é importante que o cirurgião-dentista tenha conhecimento para realizar seu correto diagnóstico e plano de tratamento(AU)

RESUMEN Introducción: Las exostosis son definidas como bultos óseos, de carácter benigno, y contituyen una infrecuente afección en bebés. Objetivo: Describir un caso de exostosis palatina bilateral en un bebé melanoderma del sexo femenino de 1 año y 4 meses de edad. Presentación del caso: La niña acudió a la Clínica Escuela de Odontopediatría, con su madre, para evaluación odontológica. Durante la anamnesis, la madre refiere retraso en la erupcíon de los dientes deciduos, además de la presencia de bultos en la arcada superior, sin dolores sintomáticos. Fue informado que tres familiares también presentaban la misma alteración en la maxila o mandíbula, posiblemente sugiriendo componente genético. El examen clínico intrabucal, verificó un aumento de volumen óseo bilateral plano ubicado en la maxila, en la región lingual de las tuberosidades palatinas, recubierto por una mucosa bucal normal. La superficie era rígida a la palpación y con bordes bien definidos. El componente genético fue asociado al aspecto clínico de la lesión, al igual que el sexo y la etnia. El diagnóstico establecido fue exostosis palatina bilateral. La biopsia y el tratamiento activo para la remoción de la afección no se pudieron justificar por la poca edad de la niña, ausencia de dolores sintomáticos, además de interferencias en la alimentación, deglución u otra función bucal. La paciente fue controlada periódicamente y presentó secuencia de irrupción de dientes deciduos normal. Conclusiones: Aunque la exostosis palatina sea infrecuente en niños, es importante que el cirujano dentista tenga conocimiento para realizar el correcto diagnóstico y el plan de tratamiento(AU)

ABSTRACT Introduction: Exostoses are localized bony lumps of a benign nature. They are an infrequent condition in infants. Objective: Present a case of bilateral palatal exostosis in a dark-skinned female infant aged one year and four months. Case presentation: The girl was brought by her mother to the Children's Dental Clinic for oral examination. During anamnesis, the mother referred to delay in the eruption of deciduous teeth and the presence of lumps on the upper arch without any painful symptom. She also reported that three relatives had the same alteration in their maxilla or mandible. Oral examination revealed a bilateral flat bony lump in the maxilla, in the lingual region of the palatal tuberosities, covered by normal oral mucosa. The surface was stiff to palpation with well defined borders. The genetic factor was associated to the clinical aspect of the lesion, as well as the sex and ethnicity of the patient. The diagnosis was bilateral palatal exostosis. Biopsy and active treatment for removal of the lesion were not justified due to the patient's age, absence of painful symptoms, and potential interference with feeding, swallowing and other oral functions. The patient was periodically followed-up and was observed to present a normal process of deciduous tooth eruption. Conclusions: Even though palatal exostosis is infrequent in children, it is important for dental surgeons to be knowledgeable about the topic so as to reach an appropriate diagnosis and treatment plan(AU)

Mortarmen's Knee: Adult-Onset Tibial Tubercle Exostoses in 2 Infantrymen.

Two 20-year-old male patients presented together to a multidisciplinary primary care sports medicine clinic with reports of focal swelling and pain at the left anterior knee just distal to the patella. Both patients enlisted together, chose the same occupational specialty, and trained together, resulting in similar exposure to training loads. Following examination, radiographic imaging was ordered for both patients. Radiographs of both patients revealed exostosis and fragmentation, with multiple ossicles of the tibial tubercle.

Scuba diving and otology: a systematic review with recommendations on diagnosis, treatment and post-operative care.

Scuba diving is a popular recreational and professional activity with inherent risks. Complications related to barotrauma and decompression illness can pose significant morbidity to a diver's hearing and balance systems. The majority of dive-related injuries affect the head and neck, particularly the outer, middle and inner ear. Given the high incidence of otologic complications from diving, an evidence-based approach to the diagnosis and treatment of otic pathology is a necessity. We performed a systematic and comprehensive literature review including the pathophysiology, diagnosis, and treatment of otologic pathology related to diving. This included inner, middle, and outer ear anatomic subsites, as well as facial nerve complications, mal de debarquement syndrome, sea sickness and fitness to dive recommendations following otologic surgery. Sixty-two papers on diving and otologic pathology were included in the final analysis. We created a set of succinct evidence-based recommendations on each topic that should inform clinical decisions by otolaryngologists, dive medicine specialists and primary care providers when faced with diving-related patient pathology.

Nonoperative management of retrocalcaneal pain with AFO and stretching regimen.

BACKGROUND: Retrocalcaneal heel pain is caused by a spectrum of etiologies all resulting in the same symptom of pain at the tendon-Achilles insertion. Several studies have reported the outcomes of operative treatment, but none have reported the outcomes or success rates of nonoperative treatment. We describe a detailed treatment algorithm and report the clinical outcomes. METHODS: One hundred thirty-five patients were prescribed a treatment regimen consisting of an AFO and stretching program and were enrolled in our prospective study. One hundred three patients completed pre- and post-treatment Foot Function Indices and were included in the analysis. The effect on FFI from clinical and radiographic factors was examined. RESULTS: Of the study population, 76% had a BMI greater than 25, 80% were older than 50 years, and 75% had an exostosis on radiographs. The mean pre-treatment FFI was 48.4 and the mean post-treatment FFI was 18.6 indicating a statistically significant improvement in function of 29.8. Neither BMI nor age had a significant effect on the magnitude of improvement; though, smokers had significantly less improvement. FFI improvement in patients with an exostosis were less than those without an exostosis. Patients with an exostosis less than 1 cm had less improvement than those with an exostosis of 1 cm or more. Patients with Types I and III exostoses had significantly less improvement in FFI compared to Types II and IV. Twelve of the 103 (11.6%) were not pleased with the results of nonoperative treatment and elected to have a procedure performed. CONCLUSION: Our study is the first to report the outcome of non operatively treated retrocalcaneal heel pain and to classify retrocalcaneal exostoses. Using our treatment algorithm, we had an 88% success rate in alleviating symptoms and avoiding surgery. Our data suggests that the use of an AFO and stretching regimen may benefit patients suffering from retrocalcaneal heel pain.

Hand ischemia caused by solitary humeral exostosis irritating the brachial artery.

A 39-year-old woman presented with ischemia of the left hand. Angiography revealed thrombosis of forearm arteries. Surgical intervention was unsuccessful. CT angiography revealed an exostosis on the distal humerus close to the brachial artery which we believe was the cause of repetitive minor trauma to the brachial artery leading to embolic occlusion of the radial and ulnar arteries. Early diagnosis of the underlying cause is the key to successful treatment of hand ischemia. For patients without risk factors for arterial occlusive disease, imaging of bony structures must be performed in order not to miss the likely cause of an insidious repetitive vascular trauma.

Painful prominences of the heel.

Heel pain is a common malady, with reported prevalence ranging from 4% to 21%. Referral to foot and ankle specialists for heel pain is also common, but patient awareness of the cause of heel pain may be limited. Many misconceptions about how heel exostoses relate to heel pain exist in the medical community and the general patient population, with many patients referred for or presenting with the simple complaint ''I have a heel spur.'' This article reviews the common exostoses of the heel, including plantar, lateral, and posterior spurs, with specific attention to the cause and treatments.

Suture exostosis causing obstruction in the nasolacrimal duct in three horses.

CASE HISTORY: Three horses were presented with facial swelling and epiphora. CLINICAL FINDINGS: All horses had facial swellings and radiographic findings consistent with exostosis at the lacrimomaxillary suture, and ipsilateral epiphora. Positive contrast dacryocystorhinography demonstrated that the site of obstruction of the nasolacrimal duct was located where the duct traverses the lacrimomaxillary suture. DIAGNOSIS: Lacrimomaxillary suture exostosis. CLINICAL RELEVANCE: Lacrimomaxillary suture exostosis should be considered as a differential diagnosis in cases of epiphora in horses. Dacryocystorhinography, preferably retrograde and normograde, may be used as an aid to diagnosis.

Exostosis subungueal en un adolescente de 14 años / Subungual exostosis in a 14 yaears old boy

La exostosis subungueal es un tumor benigno de hueso trabecular rodeado por una cápsula fibrocartilaginosa; aparece principalmente en la falange distal del hallux, por debajo de la uña o adyacente a ella y se manifiesta clínicamente por alteración de la uña suprayacente o de los tejidos blandos periunguales, respectivamente. Es infrecuente en la infancia y más común en el sexo femenino. La sospecha clínica se confirma por el hallazgo radiológico (placa de perfil) de una excrecencia de hueso trabecular que se proyecta desde la superficie dorsal de la falange distal del dedo afectado. El tratamiento de elección consiste en el legrado o remoción quirúrgica de la lesión. Presentamos un caso de exostosis subungueal localizada en el halllux en un varón de 14 años de edad, con la tríada característica de esta entidad: dolor digital, lesión subungueal con deformidad de la lámina ungueal y hallazgos radiográficos característicos.(AU)

Tumours and tumour-like lesions of the hip in the paediatric age: a review of the Rizzoli experience.

Bone tumours and tumour-like lesions of the hip in children are rare. Signs and symptoms of these tumours are generally nonspecific. Delay of diagnosis is not uncommon. A high index of suspicion in young patients presenting with persistent pain and without history of trauma, that is unresolved with conservative therapy should prompt further investigation, including radiographs or computed tomography scan of the pelvis. In the experience of the Istituto Rizzoli, in patients less than 14 years (mean 9 years, ranged from 6 months to 14 years), 752 tumours and tumours-like lesions occurred in the pelvis or proximal femur, involving the hip. Tumour-like lesions accounted for 322 cases (simple bone cyst in 255, eosinophilic granuloma in 43, aneurismal bone cyst in 34), benign tumours for 340 cases (osteoid osteoma in 229, fibrous dysplasia in 63, exostosis in 48) and malignant tumours for 80 cases (Ewing's sarcoma in 53 and osteosarcoma in 27). The epidemiology, pathology, clinical presentation, and radiograph findings are discussed for each of these tumours.Treatment of these tumours differs from observation or minimally invasive treatment for most pseudotumoural lesions, intralesional excision or termoablation for benign bone tumours and wide resection for malignant bone tumours. In this latter group, chemotherapy is required and often administered pre- and postoperatively.

Common nail tumors.

Nail abnormalities are varied and numerous. They include warts, keratoacanthomas, onychomatricomas, fibrokeratomas, osteochondromas, tumors (ie, glomus, giant cell, Koenen's, and others), and Bowen's disease. Although the gravity of these conditions may vary, prompt diagnosis and treatment is of the utmost importance. This article discusses the most common defects associated with the nail unit and its surrounding tissue, as well as the differential diagnosis and treatment of these conditions.

Modified surgical approach for retrocalcaneal exostectomy with early return to weight bearing.

This procedure is a minimally invasive method of excising a retrocalcaneal exostosis and has been performed at the authors' facility for several years with excellent results and no incidence of Achilles tendon compromise. Postoperative recovery and return to weight bearing are accelerated compared with procedures that reflect the Achilles tendon from its insertion.

Extracorporeal shockwave therapy (ESWT) in patients with chronic proximal plantar fasciitis.

The aim of this study was to compare the effect of extracorporeal shockwave therapy (ESWT) in patients with chronically painful proximal plantar fasciitis with a conventional conservative treatment consisting of nonsteroidal anti-inflammatory drugs, heel cup, orthoses and/or shoe modifications, local steroid injections and electrotherapy. Forty-seven patients (49 feet) with a previously unsuccessful conservative treatment of at least six months were randomized to two groups. Treatment of Group 1 (25 heels) started immediately with three sessions of ESWT (3000 shockwaves/session of 0.2 mJ/mm2) at weekly intervals. In the patients of Group 2 (24 heels) treatment was continued for 12 weeks. After this period they were treated using the protocol of Group 1. No significant difference of pain and walking time after further non-ESWT treatment (three months) was seen. Six months after ESWT pain decreased by 64% to 88% on the visual analog scale (VAS) and the comfortable walking time had increased significantly in both groups.
