The aim of this study was to evaluate acellular dermal matrix graft (ADM) combination with laterally positioned flap (LPF) and to compare the results with LPF alone in terms of root coverage, esthetics, and patient perspectives in gingival recessions.
Materials and methods
Twenty-two patients with localized Miller Class I/II recessions ≥ 3 mm with gingival thickness (GT) < 0.8 mm were included. Outcome parameters such as recession height and width, keratinized tissue (KT) height, GT, mean and complete defect coverage, patient satisfaction, and root coverage esthetic score (RES) were re-evaluated at 12 months postoperatively.
Results
Mean and complete defect coverage were 94.80 and 72.73% in LPF+ADM group and 77.25 and 45.45% in LPF group, respectively. Significant differences were observed for KT and GT gain, patient satisfaction, and RES in favor of LPF group (p < 0.05). A significant positive correlation was established between GT and mean defect coverage (r = 0.448; p < 0.05).
Conclusion
LPF is a successful approach in the treatment of localized Miller I/II gingival recessions. On the other hand, when thin donor tissue was thickened with an allogenic graft, more successful results regarding complete defect coverage, patient satisfaction, and RES were obtained.
Clinical relevance
Increase in gingival thickness and keratinized tissue height represents critical improvements in the prognosis of the advanced localized recessions and will be beneficial for patient’s periodontal health and esthetics. Both approaches can be used successfully as an alternative for soft tissue root coverage in specific localized cases with a limited amount of keratinized tissue apical to the defect.
A case with sudden sensorineural hearing loss (SSNHL) owing to multiple sclerosis (MS) who had clinical and dramatic radiological improvement just after medical therapy was reported in this article.
Method
Case report and review of related literature.
Results
A 22-year-old female patient with MS related SSNHL was presented in this article. Magnetic resonance imaging (MRI) revealed an MS plaque localized at pons extending from right cochlear nucleus to proximal part of the right cochlear nerve. Most dramatic recovery was present in the 5th day control MRI, where the plaque located on pons disappeared completely. On the 10th day control audiogram hearing recovery was observed and pure tone audiogram levels were almost normal.
Conclusion
Sudden sensorineural hearing loss owing to MS is seen more common than expected. It has good prognosis. Magnetic resonance imaging is also thought to have an important role in diagnosis and treatment efficacy of SSNHL owing to MS. 相似文献
Background No-reflow developed after coronary revascularization is an independent predictor of in-hospital mortality and poor clinical
outcome. In this study, we investigated the difference between direct stenting and stenting with predilation, regarding to
development of no-reflow in patients with acute coronary syndromes (ACS) and the role of fibrinolytic system in that phenomenon.
Methods Fifty eight patients with the diagnosis of ACS in whom percutaneous coronary intervention (PCI) was applied were included
in study. Patients were divided into two groups according to stent application with and without predilation. Pre- and post-intervention
corrected TIMI frame counts (cTFC) were calculated. Post-PCI plasminogen activator inhibitor-1 (PAI-1), tissue plasminogen
activator (tPA), plasminogen and D-Dimer levels were measured.
Results Pre-intervention cTFC values were similar between stenting with and without predilation groups (P > 0.05). There was a significant decrease in post-intervention cTFC values in both groups (P < 0.002 and P < 0.05, respectively). But, there was no significant difference between post-intervention cTFC values of the groups, regardless
to stent implantation techniques. (P > 0.05). In patients having high cTFC values compared with having low cTFC values; PAI-1 (P = 0.002), tPA (P = 0.015), plasminogen (P = 0.040) and D-dimer (P = 0.049) levels were significantly higher. Also, significant relationship was determined between cTFC and PAI-1, tPA, plasminogen,
D-dimer levels (P values 0.003, <0.05, <0.05, and <0.002, respectively).
Conclusions Results of this study indicated an important role of increased fibrinolytic activity in development of no-reflow phenomenon
after PCI. We didn’t observe any differences between direct stenting and stenting with predilation according to the occurrence
of no-reflow. 相似文献
Background: Cardiovascular diseases are responsible for about half of deaths and are the major cause of mortality in hemodialysis patients. The aim of this study is to assess left ventricular (LV) longitudinal myocardial functions by color tissue Doppler imaging (TDI) in patients with chronic renal failure on a regular hemodialysis program. Methods: Thirty-one patients on a regular hemodialysis program (mean age 47 ± 12 years; 17 males, 14 females) were included into the study. Twenty-three healthy subjects (mean age 44 ± 8 years; 15 males, 8 females) were studied as a control group. The patients had been on maintenance hemodialysis for at least 1 month and hemodialysis sessions were three times per week. For color TDI, apical two- and four-chamber views of left ventricle were used. Sample volumes were placed on the mid-left ventricle in the inner half of the myocardium at the septum, lateral, inferior, and anterior walls. Peak LV strain, peak systolic strain rate, peak early diastolic strain rate, peak late diastolic strain rate, peak systolic tissue velocity, peak early diastolic tissue velocity, and peak late diastolic tissue velocity values were measured. Results: Mean peak LV strain, mean peak systolic strain rate, and mean peak systolic tissue velocity values were all lower in the hemodialysis group. Although mean peak late diastolic strain rate and mean peak late diastolic tissue velocity values were similar between the groups, mean peak early diastolic strain rate and mean peak early diastolic tissue velocity values were lower in the hemodialysis group. Conclusion: Patients with chronic renal failure on regular hemodialysis program show significant alterations at LV longitudinal myocardial function parameters assessed by color TDI. 相似文献
Carcinoma ex pleomorphic adenoma (CXPA) is a malignant transformed variant of pleomorphic adenoma (PA). Generally it presents with a rapidly growing mass in the parotid gland within a preexisting PA or following surgical resection of PA. Mainstream treatment modality is surgical resection followed by radiotherapy if necessary. Facial nerve preservation and complete resection of the tumor are the main principles of the operation. Giant malignant derivates are not seen frequently and constitute a challenging task for surgeons to achieve the main principles of resection. Prognosis of CXPA is poor and aggressive treatment should be performed immediately after the diagnosis. We present a 82-year-old woman with a giant malignant parotid gland mass who was successfully treated with surgery without any facial nerve injury. 相似文献
