Reabilitação oral em implantodontia após ressecção óssea / Oral rehabilitation in implantology after bone resection

Introdução: determinadas patologias ósseas provocam ressecções que interferem nas funções maxilo-mandibulares. Alguns procedimentos são importantes para a reabilitação desses pacientes, como enxerto ósseo autógeno e distração osteogênica. Métodos: o presente trabalho relata o caso da paciente E.S.S., 26 anos, que, após constatação de lesão óssea na região anterior da mandíbula, foi encaminhada ao Hospital Universitário João de Barros Barreto, onde se diagnosticou fibroma ossificante. O tratamento foi realizado com ressecção parcial de mandíbula e posteriores cirurgias de reconstrução óssea da região, com enxerto autógeno e distração osteogênica. Resultado: após intervenções, conseguiu-se qualidade e volume ósseos suficientes para receber implantes, possibilitando-se a reabilitação oral com prótese. Conclusão: é importante a inter-relação entre as especialidades de cirurgia buco-maxilo-facial, implantodontia e prótese em pacientes que necessitam de reabilitação oral... (AU)

Introduction: Specifics bones pathologies lead to resections that interfere in the maxillo-mandibular functions. Some procedures such as autogenous bone grafting and distraction-osteogenesis technique are of importance to the rehabilitation of these patients. Method: This paper reports the 26 years old patient E.S.S.'s case, who had been referred to the caring of the João de Barros Barreto University Hospital after observation of a bone injury in the anterior mandibular. It was verified in the diagnosis an ossifying fibroma. The injury had been treated undertaking a partial jawbone resection followed by bone reconstruction surgeries with autogenesis graft and distraction osteogenesis in the region. Results: After these interventions, it was achieved enough bone volume and quality that allowed receiving implants, moreover, the oral rehabilitation with prosthesis. Conclusion: It is necessary an interrelationship between the expertises in Oral and Maxillofacial surgery, Implantology and Prosthesis in cases of patients that need oral rehabilitation... (AU)

Analysis of twenty pediatric cases of tuberous sclerosis complex: are we doing enough?

BACKGROUND: Tuberous sclerosis complex (TSC) is a neuro-cutaneous disease characterized by hamartoma formation in various organs particularly the skin, brain, eye, kidney, heart and lungs. Patients usually have multisystem involvement and thus present to different medical specialties with varied complaints while the true nature of the disease and the hidden manifestations may remain unattended. AIM: To assess the frequency and characteristics of various cutaneous and systemic manifestations in TSC and the total impact on different system in a cohort of pediatric patients. METHODS: The study included 20 patients fulfilling the diagnostic criteria for TSC from dermatology, pediatrics, and neurology department. Detailed history, examination, and investigations such as chest X-ray, electrocardiography (ECG), ultrasonography (USG) abdomen, echocardiography, fundoscopy, computed tomography (CT) scan of brain and abdomen were done. RESULTS: Dermatological manifestations included ash leaf macules, angiofibromas, shagreen patch, and fibrous plaque. Systemic findings observed were subependymal calcified nodules, subependymal giant cell astrocytoma, cortical tubers, renal cysts, angiomyolipomas, lung cyst, retinal hamartomas, mental deficits and epilepsy. LIMITATION: Wechsler's Intelligence Scale for Children would have been more appropriate for assessing the intelligence. Dental check-up was not done in our group of patients. CONCLUSION: Our study highlights the wide variety of cutaneous and systemic manifestations of TSC. The study emphasizes the need for comprehensive multidisciplinary treatment and periodic follow-up which are necessary for appropriate management of this multisystem disorder. Counseling regarding education and rehabilitation of the patients and genetic counseling of parents are important.

Human papillomavirus and skin tags: is there any association?

BACKGROUND: Low-risk human papillomavirus (HPV) infections are related to the genesis of various benign lesions. In an isolated report available, HPVs have been implicated in the causation of skin tags too. AIMS: The present study was designed to detect the existence of low-risk HPV types 6 and 11 in cutaneous soft fibromas (skin tag) in north Indians. METHODS: A total of 37 cases of skin tags from various sites were analyzed. Highly sensitive and comprehensive polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) assays were done for the detection of low-risk HPV types 6 and 11. RESULTS: The results revealed the presence of HPV DNA 6/11 in 48.6% of the skin tags examined by PCR-RFLP. CONCLUSION: This result corroborates the hypothesis that HPV plays a part in the etiology of benign lesions like cutaneous soft fibromas. The identification of HPV 6/11 in these lesions, which are benign proliferations of the skin, further expands the spectrum of HPV-linked lesions.

Tuberous sclerosis with portal vein thrombosis, protein C and S deficiency.

A 29-year-old lady with a bad obstetric history and portal vein thrombosis, presented to the Skin OPD for facial lesions. On examination, angiofibromas on face, shagreen patch and periungual fibromas were observed. She also had dental pits and a retinal hamartoma. Investigations revealed hamartomas in the brain and kidney. Hematological work-up showed protein C and S deficiency with Factor V Leiden positivity. Except for the cutaneous symptoms, the patient did not have any clinical manifestations in other organs affected by tuberous sclerosis. A similar association of tuberous sclerosis with protein C deficiency has been reported in only one case in literature.

Juvenile hyaline fibromatosis in siblings.

Juvenile hyaline fibromatosis (JHF) is a rare, autosomal recessively inherited disorder. We report two siblings with multiple large tumors on the scalp, translucent papules on the nape of the neck, hypertrophic gingiva, and severe flexural contractures of large joints. The histopathology from the skin lesions showed features characteristic of juvenile hyaline fibromatosis. The cases are being reported on account of the extreme rarity of the condition.

Pseudotumor resulting from atypical mycobacterial infection: a "histoid" variety of Mycobacterium avium-intracellulare complex infection.

A 54-year-old immunosuppressed cardiac transplant recipient with a six-month history of progressive swelling of the hand, with nodules and linear lymph node chain enlargement, diagnosed as a sporotrichoid Mycobacterium avium-intracellulare pseudotumor is described. The microscopic features closely resembled the previously described histoid variety of lepromatous leprosy. Routine hematoxylin and eosin staining suggested a spindle cell neoplasm rather than an infectious or inflammatory process. An infectious etiology was pursued on the basis of the clinical setting.

Multicentric reticulohistiocytosis.

Multicentric reticulohistiocytosis is a histiocytic disorder affecting primarily skin and joints but occasionally involving other organ systems as well. A case is presented and the disease is reviewed, including discussion of historical, clinicopathologic, radiologic, etiologic, therapeutic, and prognostic aspects.
