- Solitary cystic lymph neck node metastasis of occult thyroid papillary carcinoma(2008) González García, R.; Román Romero, Leticia; Sastre Pérez, Jesús; Rodríguez Campo, Francisco José; Naval Gias, LuisThe appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often misdiagnosed due to the more frequent branchial cyst in young people. Although oronasopharyngeal squamous cell carcinoma has been reported as the main cause of lymph neck node metastasis, thyroid papillary carcinoma may be responsible for solitary cervical cystic masses as the initial manifestation of the disease. This situation has been rarely reported, although solid masses are much more frequent. In most of these cases all such lesions may initially be considered as metastatic foci from a primary thyroid lesion. However, an alternative explanation by means of which ectopic thyroid tissue is associated with a branchial cyst has to be considered, especially if no primary tumour is observed in the histological examination of the thyroid gland. We present a rare case of solitary cystic lymph node metastasis of occult papillary carcinoma of the thyroid. We also discuss possible ethiology for thyroid papillary carcinoma in lateral neck cysts.
- Dietary habits and oral health related behaviors in relation to DMFT indexes of a group of young adult patients attending a dental school(2008) Akarslan, Zühre Zafersoy; Sad?k, Burak; Sad?k, Elif; Erten, HülyaObjectives: The aim of the present study was to investigate the dietary habits and oral health related behaviors in relation to the dental health status in terms of decayed, missing and filled teeth (DMFT index) of a group of young adults attending to a dental school located in a major city in Turkey. Study Design: A total of 416 young adults (247 females and 169 males) with an age range of 18-25 (Mean 23.2 sd 0.97) attending the Oral Diagnosis department participated in the study. The patients completed a questionnaire including questions about demographic factors, dietary habits and oral health related behaviors. Subsequently, the DMFT index and plaque index was calculated. Descriptive statistics, Mann Whitney U/ Kruskal Wallis Variance analysis, Chi-square/ Fisher?s Exact tests and multiple linear regression analysis were used for statistical analysis of the data when applicable. Results: According to the results of the study, approximately 70% of the patients had regular main meals and a very high snacking rate (76.9%) was present. Although not at a high rate, most of the patients brushed their teeth regularly twice a day (44.2%) and approximately half used other hygiene aids in addition to brushing (43.8%). The median of the DMFT index was 5 and a majority of the patients had moderate plaque accumulation which could be seen with the naked eye (45.0%). Dental plaque had the most significant effect on the DMFT index. Conclusion: In conclusion, advice, including importance of regularity of main meals, decrease in snacking frequency, regular brushing twice a day and the use of other oral hygiene aids for the elimination of dental plaque would be helpful to enhance the dietary habits and oral health related behaviors of young adult Turkish patients.
- Cervical necrotizing fasciitis : an unusual sequel of odontogenic infection(2008) Subhashraj, Krishnaraj; Jayakumar, Naveen; Ravindran, ChinnasamyCervical necrotizing fasciitis is a rare infection of the fascial planes, which is less common in head and neck, because of the rarity and higher vascularity in the region. We reviewed five patients with cervical necrotizing fasciitis of odontogenic infection managed at a teaching hospital at Chennai, India. There were four men and one woman, of whom four patients were diabetic and hypertensive, with a mean age of 53 years. Mandibular molars (periapical or pericoronal abscess) were found to be the source of infection in all of the cases. The treatment involved incision and drainage and debridement. Anti-microbial drugs were given for all the patients, which included cephalosporins, metronidazole and gentamycin. In four patients the wound healed by contracture and one patient required split skin grafting. Due to the smaller extent of the necrosis, better control of the systemic disease and small size of the sample, there was neither a major complication nor death. This paper reminds us that cervicofacial necrotizing fasciitis (CNF) remains one of the potential complications of long standing odontogenic infections in patients with immunecompromised status, particularly in lower dentition.
- Rhinoorbitocerebral mucormycosis : A case report and literature review(2008) González Martín-Moro, Javier; López-Arcas Calleja, José Mª; Burgueño García, Miguel; Cebrián Carretero, José Luis; García Rodríguez, JulioMucormycosis is a rare oportunistic infection typically described in diabetic patients with a ketoacidotic status, as well as neutropenic patients. The infection is caused by a group of saprophytic fungi of the class Phycomicetes, being the most frequent ones the Rhizomucor, Rhizopus and Mucor. Its hystological findings include vascular trombosis and tissue necrosis, predominantly in the rino-orbito-cerebral area. Even though the frequency of presentation is very low, given its rapid evolution and severe consequences which include a high mortality rate, it is very important to be aware of the main features of the disease and treat it promptly. Although the diagnosis is based on the high clinical suspect, the computed tomography (CT) and the magnetic resonance image (MRI) plays an important role in determining the extension. The patients should receive treatment in a reference hospital so that a multidisciplinary approach is ensured. In this sense, we present a case of rhino-orbito-cerebralmucormycosis in a diabetic patient, recently treated in our Department. A comprehensive review of the literature has been performed to update the physiopathology and diagnosis. Finally, we describe the different treatment options focusing in the surgical approach, as well as the medical treatment with amphotericine and posaconzole
- Patient?s perception of improvement after surgical assisted maxillary expansion (SAME) : pilot study(2008) Rocha, Nelson Studart; Cavalcante, Josuel Raimundo; Silva, Emanuel Dias de Oliveira; Caubi, Antônio Figueiredo; Filho, José Rodrigues Laureano; Gondim, David Gomes de AlencarObjective: Clinicians often assume that changes following orthognathic surgery are both physically and psychologically beneficial to the patient. The present study investigates patient perception regarding improvement after surgically assisted rapid maxillary expansion. Study design: A survey with twenty-three patients was carried out to identify satisfaction with the surgical outcome and assess whether the surgery met patient expectations. General information was also collected on schooling, age, gender, chief complaint and reasons for seeking treatment. Results: Most patients (n = 19; 82%) were advised to undergo surgery by a dentist. Twenty-two (95%) patients reported being satisfied with the operation procedure. Twenty-one (91%) patients reported that the procedure met their expectations. Nineteen respondents would undergo the same operation again and would recommend treatment to others with similar problems. Conclusion: The need for surgery associated with orthodontic appliances to correct a transverse maxillary deficiency requires a proper explanation to patients regarding the procedure and postoperative period in order to ensure realistic expectations concerning the surgical goals.
- Repositioning of the inferior alveolar nerve in cases of severe mandibular atrophy. : A clinical case(2008) Castillo Pardo de Vera, José Luis del; Chamorro Pons, Manuel; Cebrián Carretero, José LuisImplant-based rehabilitation of edentulous mandibular posterior sectors tends to be complicated by the presence of bone atrophy. Following tooth loss, cortical bone suffers greater resorption on the vestibular than on the lingual aspect, and patients typically present narrow and low alveolar crests. In cases of moderate to severe mandibular atrophy, the bone height between the alveolar crest and the dental canal is small, and sometimes limited to only a few millimeters. Implant placement in such situations is very difficult, and implies the risk of inferior alveolar nerve damage. In certain cases bone grafting may be considered to restore the alveolar crest. We present a case of severe mandibular atrophy in which inferior alveolar nerve repositioning and implant placement were carried out. Such nerve repositioning may constitute a treatment alternative in patients with severe posterior sector mandibular atrophy and a consequent risk of dental nerve damage during the placement of dental implants.
- Orofacial Rhabdomyosarcoma : report of a case and review of the literature(2008) Gordón Nuñez, Manuel Antonio; Piva, Marta R.; Dos Anjos, Edvaldo D.; Freitas, Roseana A.Rhabdomyosarcomas (RMS) are among the most common soft-tissue tumors in children. These tumors are derived from mesenchymal tissue with a tendency toward myogenic differentiation that probably originates from immature and highly invasive satellite cells associated with the embryogenesis of skeletal muscle. Some of these tumors are associated with high rates of recurrence and metastasis. The diagnosis is made by microscopic analysis and auxiliary techniques such as immunohistochemistry, electron microscopy, cytogenetic analysis, and molecular biology. We report here a case of orofacial RMS in a 4-year-old child and provide an updated review of the literature, focusing mainly on the clinicopathological aspects, diagnosis and treatment of RMS of the head and neck.
- Bisphosphonate-associated osteonecrosis of the jaw : a proposal for conservative treatment(2008) Bocanegra Pérez, Sacramento; Vicente Barrero, Mario; Sosa Hernández, Manuel; Knezevic, Milan; Castellano Navarro, José María; Rodríguez Millares, JoséThe use of bisphosphonates (BPs) has proven effective in the treatment of bone-related diseases, despite the potential risk of developing osteonecrosis of the jaw (ONJ). So far, results for the treatment of ONJ have not been satisfactory. In our study, we have treated two patients diagnosed with ONJ. In addition to local treatments a hydrogel was applied, with promising results. The fistulae disappeared 2-3 weeks into the treatment. After a six-month follow-up period there has been no sign of recurrence. The extent of maxillary bone exposure has diminished notably, although not entirely disappeared. In all cases, the patients exhibit no other symptoms (they suffer from no pain or swelling or functional impotence). For this reason we believe this protocol might be useful in the case of patients who suffer from pain and fistulation secondary to BP-associated ONJ to improve the state of their lesions until definitive treatment can be undertaken. Although these findings are not conclusive, given that we are reporting data on two patients only, we believe that this might be an alternative treatment in refractory cases where other therapies are counter-indicated. A controlled randomized and prospective study would be required to confirm our findings.
- Prader Willi Syndrome : Saliva quantification and culture in 10 patients(2008) Cuba González, Laila; García Villa, Cristina; Cahuana, A.Prader Willi Syndrome (PWS) is a relatively rare neurogenetic illness. It is of interest to dentists for its clinical characteristics. The aim of this study was to evaluate the amount of saliva and the presence of Streptococcus mutans (S mutans) in patients with this syndrome. We measured saliva stimulated by chewing paraffin tablets for 5 minutes, and cultured saliva samples in order to determine the colony-forming units (CFUs) of S mutans. The study was conducted in a group of 10 children with PWS at the Hospital Sant Joan de Déu, Barcelona. Results showed that patients with PWS had lower saliva secretion than considered normal for a standard population and most cultures presented a high number of colony-forming units. We conclude that these patients are likely to present caries, and stress the need to place special emphasis on prevention.
- Oral implants in patients receiving bisphosphonates : a review and update(2008) Mínguez Serra, María Paz; Salort Llorca, Cesar; Silvestre Donat, Francisco JavierThis rewiew was mad to establish the convenience of dental implant treatment in patients receiving bisphosphonates or programmed to receive such drugs, with a description of their mechanisms of action and the way in which they can affect the mandibular or maxillary bone of dental implant candidates. In turn, a description is provided of the key elements for evaluating the benefit-risk ratio in patients treated with bisphosphonates who require oral surgery. Clinicians must be aware of the potential risk of osteonecrosis in patients treated with bisphosphonates via the oral or intravenous route. When bisphosphonates are administered via the intravenous route, all invasive oral procedures (including implant surgery) are contraindicated, and should be avoided unless absolutely necessary. The indications are more controversial in the case of bisphosphonates administered via the oral route. There is little literature on the influence of oral bisphosphonates upon bone repair, and there are not many published cases of mandibular or maxillary osteonecrosis among patients that receive such medication. The use of bisphosphonates is becoming increasingly widespread, and the duration of such treatment is increasing. It would be of interest to design studies to evaluate the risk factors of maxillary osteonecrosis among dental implant patients receiving treatment with oral bisphosphonates, and to define biomarkers capable of indicating the level of risk in the event of oral surgery in patients receiving such drugs.
- Desmoid tumor of the tongue(2008) Suresh, Chandra Sekharan; Ali, Aiman A.Desmoid tumors are rare neoplasms accounting for 0.03% of all neoplasms and have an estimated incidence of 2 to 4 per million per year. World Health Organization currently refers to all of the deep types of fibromatosis as desmoidtype of fibromatoses. The term ?desmoid? refers to the hard, tendon-like appearance of the tumor. The etiological factors suggested include genetic, endocrine and physical factors. About fifty percent of desmoid tumors arise in the abdominal region. The extra-abdominal desmoid tumors present a difficult problem in recognition and management especially because of the striking discrepancy between its deceptively harmless microscopic appearance and its potential to attain a large size, to recur, and to infiltrate neighboring tissues in the manner of a fibrosarcoma. Desmoid tumors are very rare in the oral cavity with less than 5% of cases constituting oral soft tissue fibromatosis. A 22-year old mentally retarded female patient with desmoid tumor occurring in the tongue is presented here.
