Implant retained overdentures in mandibular reconstruction: a case report

This case report describes the clinical and laboratory procedures used in the rehabilitation of a patient treated for oral cancer with surgery and radiation therapy. During surgery, a large portion of the mandible was removed and reconstructed with a bone graft. Following therapy, the patient was left with poor esthetics and difficulties with mastication and speech. The goal of prosthodontic treatment was to improve esthetics and restore function. This was successfully achieved through the placement of dental implants and the construction of an implant retained overdenture. A bar was employed to split the implants together and an O-ring system was chosen for retention. The decision to use this type of prosthesis and attachment selection was based on the patient's dental history, esthetic demands, and the need for stress distribution.     

Retrievable cemented crown options on implant-supported angled abutments: a case report

Nonaxial implant alignment often predicates the use of cemented of screw-retained angled abutments with inherent disadvantages, including reduced retrievability on screw loosening. The purposes of this article are to review the relative merits of cemented and screw-retained angled abutments and to present a method of ensuring retrievability of cemented angled abutments.     

Retained pieces of wood in the retromaxillary space: a case report

Detection and operative removal of wood as a foreign body in the cranio-maxillary area has received frequent attention in the literature. However, as a rule, most of the cases described are related to the orbit or the orbito-neurocranial space. Almost no literature exists on the detection and treatment of wooden foreign bodies in the retromaxillary space. The authors present an unusual case of long-term retained wood in this area in a child. The case inspires discussion of the general problem of detecting retained retromaxillary wood, even using modern diagnostic tools in this area and the question of the operative therapy, especially the most favourable surgical access.     

Exophthalmos and facial swelling: a case of limited Churg-Strauss syndrome

We report a case of vasculitis causing facial swelling and exophthalmos which on clinical and histological grounds is thought to be limited Churg-Strauss syndrome. An excellent response was achieved to high doses of systemic steroids and cyclophosphamide.     

Pseudopneumoperitoneum: a case report

A case of post-traumatic pseudocyst of the pancreas is presented. The elevated and compressed stomach showed an appearance on X-ray film which might be interpreted as free peritoneal air. The term pseudopneumoperitoneum is defined and other causes of this condition are mentioned.     

Hemangiopericytoma: a case report

We describe one case of hemangiopericytoma touching a 44-year-old man. It is a rare vascular tumor originating from pericytes surrounding capillaries. The main typical features of it are the difficulty in doing an histologic diagnosis and the impossibility to make out a reliable prognosis. The therapy of choice is a surgical procedure sometimes in combination with radio- and/or chemotherapy.     

Porcelain veneers for primary incisors: a case report

A 4-year-old boy with severely discolored primary maxillary incisors was treated with bonded porcelain veneer restorations. Two years previously, the child had been treated with topical application of sodium fluoride-silver nitrate solution to arrest dental caries associated with a nursing bottle habit. With minimal chair time, the incisors were restored with laboratory-processed porcelain veneer restorations that were bonded with resin cement. This is perhaps the only report to date of the use of porcelain veneer restorations for primary anterior teeth.     

Enchondroma protuberans: a case report

Epidemiologic studies suggest that moderate amounts of ethanol may reduce cardiovascular risk. The mechanisms of the alcohol-associated risk reduction are not known exactly. Vascular smooth muscle cell proliferation represents an important phenomenon in the pathogenesis of atherosclerosis. Recently, it was suggested that metabolic changes during the postprandial phase may be important in the pathogenesis of atherosclerosis. Therefore, we evaluated the effect of postprandial plasma with and without ethanol on the proliferation of rat vascular smooth muscle cells. Identical meals containing 1 g fat/kg body wt were given with and without ethanol (38 +/- 0.5 g) to eight healthy young men. Blood was drawn hourly during an 8-h postprandial period; the plasma was separated and added to the cell cultures (0.3%, by vol). The proliferative response (DNA synthesis) of these cells was assessed by measuring the incorporation of [methyl-3H]thymidine. The maximal blood ethanol concentration of 11.5 +/- 0.6 mmol/L (mean +/- SEM) was attained within the first hour. The ingestion of the meal with ethanol led to a 20% reduction in the capacity of postprandial plasma to induce thymidine incorporation into smooth muscle cells compared with the meal without ethanol (P < 0.05). These results suggest that ethanol may reduce cardiovascular risk by modulating vascular muscle cell growth during the postprandial period. Considering the amount of time humans spend in the postprandial state during their lifetimes, these findings may be of great importance in the pathogenesis of atherosclerosis.     

Lymphoma lymphoplasmocytoides: a case report

Clinical symptoms and haematological disorders in patients suffering from lymphoplasmatic/lymphoplasmocytoidal lymphoma were presented, 82 patients were examined (median age of 63), all of the in clinical stage IV (ANN Arbor scale). In all of the patients bone marrow was invaded. The most common symptom was enlargement of peripheral lymph nodes (86%) less often abdominal ones (21%). Splenomegalia was found in 55% and hepatomegalia in 49% of patients 35% of patients had anaemia and 38% thrombocytopenia. Close to 1/3 of patients dermatoses were found, in most cases allergic ones. In 7% another cancer was found.     

Autoerotic asphyxia: a case report

Autoerotic asphyxia is the induction of a state of oxygen deficiency to enhance sexual excitement and orgasm. It has been practiced for centuries, and there are many reports of fatalities. The authors report a case of a living participant that shows a number of characteristics different from those of fatalities. The case study also raises doubt about the conventional view that participants have no wish to die. We feel that further case studies of living participants will lead to a greater understanding of the practice and will facilitate treatment.     

Diphenylhydantoin-induced hepatitis: a case report

This case report is of a 25-year old man with severe diphenylhydantoin-induced hepatitis, fever, rash and generalized lymphadenopathy. Hepatic histology and lymphocyte transformation tests strongly supported the diagnosis. He made an uneventful recovery with supportive therapy.     

Dyskeratosis congenita: a case report

Clozapine is an atypical agent for intractable schizophrenia which was introduced into the UK at the beginning of 1990. Its lack of extrapyramidal side effects and its action on negative symptoms single it out from conventional neuroleptics. This article describes the drug's development/special monitoring and dispensing arrangements, and gives advice on how it can best be utilized.
