1/165. Papillary endothelial hyperplasia presenting as a chest wall neoplasm.Soft tissue hematomas generally resolve but may persist and develop into slow-growing, organized masses. These chronic expanding hematomas are characterized by a pseudocapsule and a predominantly necrotic central cavity, with foci of newly formed capillaries. These have been called chronic expanding hematomas or Masson's papillary endothelial hyperplasia. These lesions can mimic vascular neoplasms and must be considered in the evaluation of expanding soft tissue vascular malformations.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/165. Gustatory otalgia and wet ear syndrome: a possible cross-innervation after ear surgery.HYPOTHESIS: The chorda tympani and Arnold's nerves have close approximation to each other and their cross-innervation is possible after ear surgery. STUDY DESIGN: A retrospective study was performed with a temporal bone pathology case and two clinical cases as representatives of such a possibility. patients had severe otalgia and wet ear during gustatory stimulation. methods: A temporal bone pathology case was studied under a light microscope. earache and/or wet ear were provoked during gustatory stimulation. Wet ear was tested with iodine-starch reaction after the subject tasted lemon juice. RESULTS: The temporal bone specimen has clusters of regenerated fibers in the tympanic cavity in the area of the chorda tympani and Arnold's nerves, suggesting a possibility of mixing. There are regenerated fibers in the iter chordae anterius, showing successful bridging of the chorda tympani nerves across a long gap. Detachment of the skin over the operated mastoid bowl obscured signs in one clinical case. Another clinical case of gustatory wet ear showed objective evidence of cross-innervation with iodine-starch reaction. CONCLUSION: The detachment procedure and iodine-starch reaction were the proofs that the signs were related to regenerated fibers. This is the first report of gustatory otalgia and wet ear after ear surgery.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
3/165. Acute hemorrhage into the peritoneal cavity--a complication of chronic pancreatitis with pseudocyst: a case report from clinical practice.Acute hemorrhage due to a pseudocyst of the pancreas is a dangerous complication of chronic pancreatitis (CP). Without operative treatment, mortality is as high as 90%. Immediate recognition of this complication as well as urgent operative treatment allowing the survival of 70% of patients is imperative. Described is the case of a patient with CP and pseudocyst in which hyperamylasemia and unclarified anemia developed following sudden abdominal pain. The suspicion of hemorrhage into the peritoneal cavity was confirmed by selective visceral angiography showing hemorrhage from the splenic artery in the region of the hilus of the spleen. Operative treatment was successful. During the procedure, a ligature was applied to the hemorrhaging splenic artery and a splenectomy was carried out with 2500 ml of bloody contents being removed from the abdominal cavity. Acute hemorrhage into the peritoneal cavity as a complication of chronic pancreatitis with pseudocyst (CPP) requires immediate identification, confirmation by visceral angiography, and urgent operative treatment.- - - - - - - - - - ranking = 7keywords = cavity (Clic here for more details about this article) |
4/165. prenatal diagnosis in a family with severe type I plasminogen deficiency, ligneous conjunctivitis and congenital hydrocephalus.Severe type I plasminogen deficiency may cause severe ligneous conjunctivitis, a rare and unusual form of chronic pseudo-membranous conjunctivitis that usually starts in early infancy, but also pseudo-membranous lesions of other mucous membranes in the mouth, nasopharynx, trachea and female genital tract, and in rare cases congenital occlusive hydrocephalus. The index patient, the daughter of a consanguineous marriage, had suffered from severe ligneous conjunctivitis and had died from decompensated congenital hydrocephalus despite numerous shunt revisions. She was found to be homozygous for a non-sense mutation in exon 15 of the plasminogen gene (Trp597->Stop). In her next pregnancy, the mother asked for prenatal diagnosis of the plasminogen deficiency. Chorionic villus biopsy was performed at 12 weeks of gestation. dna analysis of the plasminogen gene by PCR and single-strand conformation polymorphism (SSCP) revealed that the fetus exhibited an identical heterozygous band pattern as observed in the healthy mother. Therefore, the fetus was heterozygous for the Trp597->Stop mutation in plasminogen exon 15. In addition, the fetus was found to be male by cytogenetic analysis and by multiplex PCR analysis using two polymorphic X-chromosomal markers (DXS424, HPRT). These findings excluded the possibility of contamination by maternal dna. It was concluded that the fetus was not at risk for ligneous conjunctivitis and its associated complications. After the birth of a healthy boy, plasminogen functional activity was shown to be 38 per cent. dna analysis confirmed prenatal molecular genetic results.- - - - - - - - - - ranking = 0.43431341494415keywords = mouth (Clic here for more details about this article) |
5/165. Factors affecting recovery of mastoid aeration after ear surgery.Fifty-six patients after tympanomastoid surgery were examined to determine recovery of mastoid aeration and various pre- and intraoperative factors such as eustachian tube (ET) function, how the mastoid mucosa had been treated during surgery and whether or not a large silastic sheet had been placed in the middle ear or a ventilation tube used. mastoid aeration recovery was confirmed by computed tomography in 27 of the 57 cases (47%) within 12 months of surgery. Among the factors examined, preservation of the epitympanic mucosa was found to be most important in mastoid aeration recovery. Use of a large silastic sheet to cover the area from the bony ET and tympanic cavity to epitympanum, aditus ad antrum or antrum was found to be of some help in recovery mastoid aeration after complete resection of the mucosa and mastoid air cells. Preoperative ET function, anterior tympanotomy and use of a ventilation tube did not influence recovery.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
6/165. The role of trisomy 8 in the pathogenesis of chronic eosinophilic leukemia.A case of chronic eosinophilic leukemia (CEL) manifesting as spinal cord compression by an extradural eosinophilic chloroma in a 32-year-old Chinese man was presented, who subsequently developed extramedullary transformation at the skin and then peritoneal cavity. Cytogenetic study of bone marrow cells at diagnosis showed a clonal karyotypic abnormality of trisomy 8 ( 8), which on fluorescence in situ hybridization (FISH) was shown to be present in a clone of abnormal eosinophils, hence showing the neoplastic nature of the eosinophilic proliferation. There was another population of abnormal eosinophils that did not show 8. At blastic transformation, all blast cells in ascitic fluid were shown by FISH to harbor 8. These findings suggest that 8 in this case may have arisen from clonal evolution and is not the primary genetic event in leukemogenesis, but 8 most probably imparts a further survival advantage to the clone responsible for subsequent blastic transformation.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
7/165. Treatment of chronic osteomyelitis of the lower extremity using free flap transfer.Between 1987 and 1995, 25 patients with chronic osteomyelitis of the lower extremity were treated by transfer of muscle or musculocutaneous flap. The subsequent follow-up extended over more than three years. Five patients developed a recurrence. Two were reoperated on and healed completely; in two an amputation had to be performed; and in one the infection persists. recurrence occurred mainly in patients in whom the bone cavity could not be filled completely with muscle.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
8/165. brain abscesses from neglected open head injuries: experience with 17 cases over 20 years.We are reviewing our experience with 17 civilian cases with post-traumatic brain abscesses treated in the era of CT scanning over a period of 20 years. The principal cause for this intracranial complication was the neglected compound depressed fracture. One was a newborn infant with left parietal abscess caused by a vacuum extraction. We have used the following methods of treating the abscesses: single burr hole aspiration in the newborn with an excellent result; repeated aspiration, with debridement of the depressed fracture, in 5 cases (1 death); aspiration with early subsequent excision, via craniotomy, in 7 cases (no death), and primary excision, via craniotomy, in 4 cases (1 death). The early subsequent excision of the abscess, 2 or 3 days after the initial aspiration, has proved in our experience very satisfactory. In cases with bone fragment into the abscess cavity the excision of the abscess is indicated. The cultured pus from the abscess cavity showed mixed flora (streptococci and staphylococci) in 7 cases; staphylococcus aureus in 4; staphylococcus epidermidis in 2, and no growth in 4 cases. Antibiotics play an important role in the treatment of post-traumatic brain abscesses.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
9/165. Complete dentures and the associated soft tissues.Some of the conditions of the soft tissues related to complete dentures encountered during a period of 25 years at a university clinic were presented and discussed from the standpoint of the clinical prosthodontist. During this time, over 1,000 denture patients were treated each year. For some conditions, a method of management was offered with treatment by sound prosthodontic principles rather than unneccessary medication. That denture fabrication involves much more than mere mechanical procedures is an understatement. Complete dentures are foreign objects in the oral cavity that are accepted and tolerated by the tissue to a degree that is surprising. As prosthodontists, we can gain satisfaction from the realization that the incidence of oral cancer due to dentures is less than extremely low. At the same time, we must be ever mindful of the statement by Sheppard and associates. "Complete dentures are not the innocuous devices we often think they are." Every dentist must remember that one of his greatest missions is to serve as a detection agency for cancer. The information discussed indicates (1) the need for careful examination of the mouth, (2) the value of a rest period of 8 hours every day for the supporting tissues, and (3) the importance of regular recall visits for denture patients. Robinson stated that while the dental laboratory technician can be trained to aid the dentist in the fabrication of prosthetic devices, his lack of knowledge of reactions and diseases of the oral tissues limits him to an auxiliary role. Complete prosthodontics is a highly specialized health service that greatly affects the health, welfare, and well-being of the patient. It can be rendered only by the true professional who is educated in the biomedical sciences.- - - - - - - - - - ranking = 2.714163762482keywords = oral cavity, cavity, mouth (Clic here for more details about this article) |
10/165. Chronic ulcerative stomatitis: a case report.BACKGROUND: Certain mucocutaneous diseases present with painful, ulcerative, or erosive oral manifestations. Chronic ulcerative stomatitis is a newly recognized disease of unknown origin which presents clinically with features of desquamative gingivitis. This report marks only the thirteenth case reported in the world literature. A review of previous reports and studies is presented along with a review of immunofluorescence techniques critical to proper diagnosis. These diseases are difficult to diagnose without the use of immunofluorescence techniques. A 54-year-old Caucasian woman presented with a 2- to 3-year history of stomatitis and dry mouth. methods: Direct immunofluorescence revealed a speckled pattern of IgG deposits in the basal one-third of the epithelium, while indirect immunofluorescence confirmed the presence of stratified epithelium-specific antinuclear antigen (SES-ANA), both pathognomonic for chronic ulcerative stomatitis. RESULTS: The patient was successfully treated using topical corticosteroid therapy.- - - - - - - - - - ranking = 0.43431341494415keywords = mouth (Clic here for more details about this article) |
