Cosmetic dentistry.

PURPOSE OF REVIEW: Patients seeking the expertise of facial plastic surgeons for facial aesthetic improvement may also desire or benefit from dental aesthetic procedures. This paper reviews current treatment options available in cosmetic dentistry. RECENT FINDINGS: Many techniques exist to improve dental aesthetics in color, position, shape, size, alignment and overall smile appearance. Although orthodontic therapy is still an important modality for smile aesthetics, some simpler procedures can provide acceptable aesthetic results. Comparison of external dental bleaching techniques reveals similar long-term results for in-office and at-home bleaching; in-office treatments, however, may provide the benefit of faster results. Internal dental bleaching is an effective method for correcting nonvital teeth coloration. Enamel shaping via either direct tooth contouring or the application of resins or veneers to tooth surfaces can correct defects, asymmetries and shape or rotation problems. Veneers or crowns are also options to correct intrinsic dental stains not amenable to bleaching techniques. Treatments to refine gingival margins and borders are another proven beneficial cosmetic procedure. SUMMARY: A myriad of techniques exist to correct a patient's particular concerns. Correction of discoloration is usually feasible as is the improvement of a patient's smile and overall dental aesthetics.

Postangiographic femoral artery injuries: nonsurgical repair with US-guided compression.

Ultrasound-guided compression repair (UGCR) of catheterization-related femoral artery injuries was evaluated as a possible new imaging-guided interventional procedure. Thirty-nine femoral artery injuries (35 pseudoaneurysms, four arteriovenous fistulas) were detected with color Doppler flow imaging in patients with enlarging groin hematomas and/or groin bruits 6 hours to 14 days after catheterization procedures. UGCR was not performed in 10 patients due to spontaneous thrombosis (n = 4), infection (n = 1) or skin ischemia (n = 1), unsuitable anatomy (n = 3), or excessive discomfort (n = 1). The remaining 29 patients underwent a full trial of compression therapy, and the lesion was eliminated in 27. Follow-up color flow scans were obtained after 24-72 hours in all 27 successful cases and at 1-15 months in 19; no recurrences or complications occurred. UGCR for acute injuries is safe and technically simple and is promising as a cost-effective, first-line treatment for uncomplicated catheterization-related femoral artery injuries. UGCR is probably not appropriate for long-standing injuries.

Amnesia for the McCollough effect following unilateral electroconvulsive therapy: implications for laterality.

The hemispheric lateralization of retrograde amnesia following unilateral electroconvulsive therapy (ECT) was measured by a novel nonverbal probe, the McCollough effect, which allowed equal and exclusive access to each hemisphere. Alternating exposure to perpendicular gratings of complementary colors (e.g., red vertical stripes alternated with green horizontal stripes) will cause subsequently presented black and white gratings to appear colored hours or even days later (the McCollough effect). Three of the patients examined (3 of 10) lost the effect in just the half visual field contralateral to the treatment side when unilateral nondominant ECT was interposed between the induction of the effect and the its test. Six patients lost the effect bilaterally following unilateral ECT. One patient retained a bilateral aftereffect. This patient had by far the shortest seizure (18 sec). Nine of 10 comparison patients, also suffering from major depression but without ECT intervening between induction and test, showed good bilateral retention of the McCollough effect. The remaining comparison patients showed no retention. These results imply that despite bilateral cortical spread of seizure activity, unilateral nondominant ECT has effects that are most pronounced over the stimulated hemisphere.

Comparing a mechanical device with medicinal leeches for treating venous congestion.

OBJECTIVE: To compare mechanical device therapy to medicinal leech therapy for treating venous congestion. STUDY DESIGN: Fasciocutaneous flaps of 9 x 7-cm (porcine model, n = 11) were elevated and the associated veins clamped for 15 hours. Device-treated flaps (n = 6) were treated with up to 3 devices/flap. Leech-treated flaps (n = 5) were treated with 75 leeches/flap (5 leeches/hour). Treatment evaluation parameters included: blood volume removed, skin color, surface perfusion, tissue oxygen tension, and endpoint histology. RESULTS: No significant differences were seen in blood volume removed, surface perfusion, and oxygen tension. However, significant differences were seen in skin color change over time. Histological assessment showed mild congestion in 5/5 leech-treated flaps and 2/6 device-treated flaps. CONCLUSION: Device therapy was comparable to leech therapy for decongesting a 9 x 7-cm flap over a 15-hour period. However, digital images and significant differences in skin color change over time demonstrate that device therapy promotes more global decongestion versus leech therapy.

Hemodynamic analysis of esophageal varices using color Doppler endoscopic ultrasonography to predict recurrence after endoscopic treatment.

BACKGROUND AND STUDY AIMS: The time to recurrence of esophageal varices may vary greatly between patients even after the same endoscopic therapy. To clarify the factors which contribute to recurrence after endoscopic treatment, the hemodynamics and morphology of the left gastric vein (LGV) were investigated using color Doppler endoscopic ultrasonography (EUS). PATIENTS AND METHODS: A total of 31 patients with high-risk esophageal varices underwent color Doppler-EUS before receiving endoscopic variceal ligation and endoscopic injection sclerotherapy combined therapy. Endoscopic examination was performed every 3 months after the treatment to evaluate recurrence of varices. RESULTS: A total of 18 patients responded to the therapy, while 13 patients did not respond, and had recurrence within 12 months. The hepatofugal flow velocity in the LGV trunk was significantly lower in the responders (9.9 vs. 13.9 cm/sec; P = 0.02). The branch pattern of the LGV was categorized into three groups: anterior branch dominant, posterior branch dominant, and no-dominant type. The incidence of the anterior branch dominant type was significantly less in responders (17 vs. 70 %; P = 0.01). There was no significant difference in the LGV trunk diameter and the size of the paraesophageal vein between the two groups. CONCLUSION: Risk factors for recurrence can be analyzed in detail using color Doppler-EUS. Further investigation using color Doppler-EUS may enable us to select the optimal way to treat esophageal varices to prevent recurrence.

Hexadecylphosphocholine may produce reversible functional defects of the retinal pigment epithelium.

Hexadecylphosphocholine is a synthetic phospholipid derivative that has antitumor activity due to its interference with membrane functions. Animal experiments have shown photoreceptor and retinal pigment epithelium (RPE) degeneration after its systemic application. In a phase II trial of hexadecylphosphocholine therapy in 23 patients with advanced metastatic colorectal or lung cancer, visual acuity and color vision testing, slit-lamp examination, tonometry, fundoscopy (including photodocumentation), visual field testing, electrooculography (EOG), and electroretinography (ERG) were performed. A baseline examination was carried out prior to therapy. Patients were reexamined after 2 months and after 5 months. In all, 71% of the patients had a reduced light peak in the EOG during therapy. After the end of therapy the light peak improved again and became normal in most patients. The statistical analysis showed that the light-peak values during therapy were significantly lower than the baseline and posttreatment values. This indicates that hexadecylphosphocholine might be capable of producing a partly reversible functional defect of the RPE. Apart from this finding, no other functional or morphological ocular side effect was detected. The functional changes observed in our patients as well as the morphological changes found in animal experiments are similar to those reported for known diseases of the RPE-photoreceptor complex. Therefore, hexadecylphosphocholine-induced retinopathy might become useful as an animal model for such diseases.

[Hybrid 3-D rendering of the thorax and surface-based virtual bronchoscopy in surgical and interventional therapy control].

PURPOSE: The aim of this study was to demonstrate the possibilities of a hybrid rendering method, the combination of a color-coded surface and volume rendering method, with the feasibility of performing surface-based virtual endoscopy with different representation models in the operative and interventional therapy control of the chest. MATERIAL AND METHOD: In 6 consecutive patients with partial lung resection (n = 2) and lung transplantation (n = 4) a thin-section spiral computed tomography of the chest was performed. The tracheobronchial system and the introduced metallic stents were visualized using a color-coded surface rendering method. The remaining thoracic structures were visualized using a volume rendering method. For virtual bronchoscopy, the tracheobronchial system was visualized using a triangle surface model, a shaded-surface model and a transparent shaded-surface model. RESULTS: The hybrid 3D visualization uses the advantages of both the color-coded surface and volume rendering methods and facilitates a clear representation of the tracheobronchial system and the complex topographical relationship of morphological and pathological changes without loss of diagnostic information. Performing virtual bronchoscopy with the transparent shaded-surface model facilitates a reasonable to optimal, simultaneous visualization and assessment of the surface structure of the tracheobronchial system and the surrounding mediastinal structures and lesions. CONCLUSIONS: Hybrid rendering relieve the morphological assessment of anatomical and pathological changes without the need for time-consuming detailed analysis and presentation of source images. Performing virtual bronchoscopy with a transparent shaded-surface model offers a promising alternative to flexible fiberoptic bronchoscopy.

[Hepatocellular carcinoma: Role of imaging diagnostics in detection, intervention and follow-up].

PURPOSE: Demonstration of techniques and clinical value of imaging diagnostics for screening, detection, interventional follow-up and therapy control of hepatocellular carcinoma (HCC). Diagnostic techniques for screening, detection and differential diagnosis of HCC are presented using color-coded duplex sonography (US), computer tomography (CT) and contrast-enhanced magnetic resonance techniques like MRI, MR angiography and MR cholangiopancreaticography (MRCP). Therapy control with imaging was performed for surgical methods like resection and liver transplantation as for well as transarterial chemoembolization (TACE), radiofrequency ablation (RF) and laser-induced thermotherapy (LITT). In screening, HCC color-coded duplex sonography reveals a sensitivity from 45 to 92 % and a specificity from 78 to 90 % when liver cirrhosis is present. The diagnostic results of CT were further improved with the newly developed techniques of multislice CT. The highest diagnostic accuracy can currently be achieved using contrast-enhanced MRI with a sensitivity from 82 to 96 %. TACE presents a palliative therapy concept; MR-guided LITT and radiofrequency ablation are used as thermoablative methods for local therapy and the therapy control is based on the above imaging techniques. Contrast-enhanced MRI proves to be the superior imaging technique for the early diagnosis, differential diagnosis and follow-up of hepatocellular carcinoma.

Detection of Helicobacter pylori colonization in dental plaques and tongue scrapings of patients with chronic gastritis.

OBJECTIVE: It has been suggested that the oral cavity and dental plaque might be a reservoir for Helicobacter pylori (Hp). In this study, our aims were to detect the prevalence of Hp colonization in dental plaque and tongue scrapings of patients with chronic gastritis and to investigate the effect of systemic treatment upon this colonization and eradication of Hp from gastric mucosa. METHOD AND MATERIALS: Eighty-one patients (49 men, 32 women) were included in the study. Dental plaque and tongue scraping specimens were obtained and assessed with Campylobacter-like organism (CLO) test, prior to endoscopic examination. By endoscopy, 2 antral and 1 corpus biopsy samples were taken for histologic examination, and 1 antral biopsy sample was taken for CLO test examination. RESULTS: Chronic gastritis was diagnosed in 63 (77.7%) of 81 patients. Dental plaque samples of 64 (79%) patients and tongue scraping samples of 48 (59.2%) patients were urease positive. Of the 63 patients with chronic gastritis, dental plaque and tongue scrapings were urease positive in 52 (83%) and 37 (59%) patients, respectively. After 14 days of triple drug therapy (omeprazole, clarithromycin, and amoxicillin), Hp was eradicated from the gastric mucosa of almost all of the patients, whereas no changes were detected in dental plaque and tongue scrapings by CLO test examination. CONCLUSION: Helicobacter pylori colonization, which seemed to be high in dental plaque and on the tongue, might play an important role in the pathogenesis of the reinfection process. In order to eradicate Hp from both the oral cavity and the gastric mucosa, studies should be performed to assess the effects of plaque control procedures in addition to present treatment modalities.

Effectiveness and safety of multidrug intracavernous therapy for vasculogenic impotence.

A four-drug vasoactive mixture (papaverine hydrochloride, prostaglandin E1, phentolamine mesylate, atropine sulfate) was used for intracavernous injection therapy in 94 patients with vasculogenic impotence as diagnosed by color Doppler sonography and dynamic infusion cavernosometry-cavernosography. At a mean follow-up of twenty months, 66 patients (70%) are using the injections with the initial dose and are satisfied; 14 patients (15%) are using the injections with a smaller dose than initially given; and 14 patients (15%) dropped intracavernous treatment. Only 4 patients (4%) were unable to achieve a sustained rigid erection during the mixture titration phase. Selected cases of vasculogenic impotence can be safely and effectively treated by the association of drugs which rely on different mechanisms of action, producing a pharmacologic synergism which enhances the overall therapeutic effect.

Partial matricectomy with a CO2 laser for ingrown toenail after nail matrix staining.

BACKGROUND: Ingrown toenail is a common nail disease that causes pain, discomfort, and difficulty in walking. It is treated with either conservative therapy or surgery. OBJECTIVE: To present a new surgical approach to ingrown toenail. MATERIALS AND METHODS: For 19 ingrown toenail borders of 14 toes in 14 patients (1 male and 13 females), the nail matrix was stained with methylene blue and then partial matricectomy was performed with a CO2 laser. RESULTS: There was no recurrence at 18 nail borders after a mean follow-up period of 13.4 months, whereas a spike grew at one border but caused no walking pain. No serious complications occurred. Cosmetic improvement was also satisfactory. CONCLUSIONS: Partial nail matricectomy with a CO2 laser after staining the nail matrix with methylene blue allows visual confirmation of the completeness of cauterization.

An evaluation of the current therapeutic regimen for renal tuberculosis.

Renal tuberculosis will continue to be a potentially lethal disease and must be considered a diagnostic possibility in all patients with infection in order to discover it in time. Multiple drug regimens have withstood the test of time and it appears that triple drug therapy is more efficacious than 2 drugs since triple drugs permit the skipping of 1 or another of the medications with less danger of relapse. Rifampin is a new drug that is well tolerated and efficacious, although expensive. We recommend continuous use of triple drugs for 2 years at least with the continuance of pyridoxine. We advise an excretory urogram, the collection of 3 urine specimens for culture and the passage of ureteral catheters every 6 months during treatment and every 12 months thereafter for 10 years. We do not consider relapse an indication for an operation but for further therapy, using medications to which the patient's organism is proved susceptible by bacteriologic means. Under modern conditions an operation is rarely necessary.

Suppression of metastatic hemangiosarcoma by a parvovirus MVMp vector transducing the IP-10 chemokine into immunocompetent mice.

We have previously shown that the growth of human tumor xenografts in immunodeficient mice can be efficiently suppressed upon infection with the autonomous parvovirus H-1 or with cytokine-transducing derivatives thereof. To further evaluate the benefits of implementing parvoviruses in cancer gene therapy, we have created a new recombinant vector, MVMp/IP-10, transducing the immunoactive, antiangiogenic chemokine IP-10, and used this virus to treat syngeneic tumors grown in immunocompetent mice. Intratumoral/intraperitoneal administration of only 3 x 10(7) replication units of MVMp/IP-10 per animal strongly inhibited the progression of established H5V cell-induced vascular tumors, a highly malignant mouse model for human cavernous hemangioma and Kaposi's sarcoma. Retardation of recurrent tumor growth and suppression of life-threatening metastatic dissemination to internal organs were accompanied by a striking delay in hemangioma-associated mortality. Parental MVMp did not have a significant effect under these conditions up to the dose of 10(10) infectious units/animal, but had strong antihemangiosarcoma activity when used to infect H5V cells ex vivo prior to implantation. In all cases, virus therapy was very well tolerated. Virus-induced suppression of hemangiosarcoma was dependent on host T cells and associated with intratumoral persistence of IFN gamma-expressing cytotoxic lymphocytes, and led to the reduced expression of hepatic plasminogen activator inhibitor-1 (PAI-1), a metastasis-linked marker. This proof of principle study demonstrates that MVMp/IP-10 can aid the treatment of vascular tumors and that autonomous parvovirus-based vectors can be considered potent tools for cancer gene therapy purposes.

Telespectrophotometric reflectance measurements for evaluating results after argon laser treatment of port-wine stain compared with natural color system notations.

Telespectrophotometric reflectance measurements are shown to give objective values of spectral changes in the port-wine stain skin after argon laser therapy. There are, however, many circumstances influencing the measurements and other factors to consider when evaluating the curves, which are hard to translate into human visual experience. Natural color system notations based on psychometric experiments, which give a cognitive description of color appearance, seem to have more value for qualitative judgement of the color change after treatment.

A novel surgical organ perfusion method for effective ex vivo and in vivo gene transfer into renal glomerular cells.

In an attempt to develop gene therapy for Alport syndrome, we have evaluated surgical methods for gene transfer into pig kidneys. For gene transfer we used an adenovirus expressing the Escherichia coli beta-galactosidase gene as a reporter gene. The viral preparation was first infused in vivo into the porcine renal artery. Then explanted kidneys were perfused ex vivo at body temperature for 12 hours with the viral solution and, finally the kidney perfusions were carried out in vivo via laparotomy for 60 and 120 minutes. Gene transfer was determined visually on histological cryosections after 5-bromo-4-chloro-3-indoyl-beta-galactopyranoside (X-gal) and periodic acid-Schiff (PAS) staining. Perfusion of whole porcine kidneys ex vivo resulted in strong expression in about 80% of glomeruli. The in vivo kidney perfusion via laparotomy for 120 minutes resulted in reporter gene expression of about 75% of the glomeruli examined after 4 days. Expression was observed almost exclusively in glomeruli, while little if any expression was found in other renal structures. The present results suggest that operatively performed kidney perfusion may be used for gene transfer in treatment of glomerular disease. This surgical approach may also prove useful for somatic gene therapy of other organs.
