Current molecular and clinical insights into uveal melanoma (Review)
2021
Uveal melanoma (UM) represents the most prominent primary eye cancer in adults. With an incidence of approximately 5 cases per million individuals annually in the United States, UM could be considered a relatively rare cancer. The 90.95% of UM cases arise from the choroid. Diagnosis is based mainly on a clinical examination and ancillary tests, with ocular ultrasonography being of greatest value. Differential diagnosis can prove challenging in the case of indeterminate choroidal lesions and, sometimes, monitoring for documented growth may be the proper approach. Fine needle aspiration biopsy tends to be performed with a prognostic purpose, often in combination with radiotherapy. Gene expres…
Marsupialization facilitates movement of the cystic lesion-associated deeply impacted mandibular third molar in spite of its mature roots
2017
Background: The odontogenic cystic lesions happened in the angle and ramus region are frequently associated with impacted mandibular third molars. The treatment plan was difficult to work out for the huge cystic lesions with deeply impacted third molars, since the enucleation with simultaneously removing the deeply impacted teeth may cause serious complications. Therefore, the marsupialization of the cystic lesions followed by enucleation with tooth removal has also been advocated. The aim of this study was to explore the movement of cystic lesion-associated deeply impacted mandibular third molars (IMTM) after marsupialization. Material and Methods: Between July 2009 and December 2015, pati…
Management of primary odontogenic myxoma
2018
BACKGROUND: This retrospective study describes our experience in the management of odontogenic myxoma. METHODS: Thirty-four patients (23 female and 11 male) with single lesions were treated. Thirty-three patients were adults (mean age 33.5 years) and one child (age 6 years). Male:female ratio was 1:2. Different surgical procedures were used to treat the tumors. 11 lesions were treated by marginal osteotomy, 12 lesions by enucleation and curettage, 11 lesions by radical treatment (segmental or block resection). The follow-up period was 5-years. RESULTS: The success rate was 73.5%. The Kaplan-Meier method was applied to examine the outcome of the treatment. Analysis showed a significant diffe…
Recurrence of odontogenic keratocysts and possible prognostic factors : review of 455 patients
2019
Background To describe epidemiological features of 565 Chinese patients with odontogenic keratocysts (OKC), to investigate possible prognostic factors related to recurrence, and to analyse features of recurrent OKC (rOKC). Material and Methods A retrospective chart review of 565 cases of OKC treated between 2003 and 2015 was undertaken. The probability of recurrence related to prognostic factors including large size, cortical perforation combined with involved teeth in the lumen of the cyst, inflammation, sites of the involved lesion, sex, and daughter cyst variables were analysed. The subsequent relapse of each OKC was compared. Results Patients ranged in age from 7 to 81 years (mean age, …
Incidence of Cardiovascular Events after Nephrectomy - A Single Centre, Matched Pair Analysis between Donor and Tumour Nephrectomy in a Long Term Fol…
2016
<b><i>Introduction:</i></b> The study aimed to compare the incidence of cardiovascular events (CVEs) after donor nephrectomy (DN) and radical tumor nephrectomy (RN), according to an estimated glomerular filtration rate (eGFR), were evaluated over time. <b><i>Materials and Methods:</i></b> Follow-up was collected for DN who underwent surgery from 1998 to 2007 for CVE and renal function. All DN were matched for age to patients treated by RN or adenoma enucleation (control group), who were eligible for DN. eGFR was estimated using the Cockgroft-Gould formula. Patients with preoperative comorbidities were excluded. <b><i>Results:</i…
Histopathology of ameloblastoma of the jaws; some critical observations based on a 40 years single institution experience
2011
The aim of the present study is to examine all cases of intraosseous benign ameloblastomas treated between 1970 and 2010 in a single institution and to look for a possible correlation between the histopathological aspects and the demographical and clinical parameters, as well as the treatment outcome. The data of a total number of 44 patients were retrieved from the records. Nine patients were excluded because of doubt about the correct diagnosis (8 patients) or because of an extra-osseous presentation (1 patient). No statistically significant differences were found between the histopathological (sub)types of ameloblastomas and the demographical and clinical parameters, nor between the hist…
Recurrence rate of odontogenic keratocyst treated by enucleation and peripheral ostectomy: Retrospective case series with up to 12 years of follow-up
2018
Background Odontogenic keratocysts have been reported with high recurrence rates in the literature so various treatment modalities from simple enucleation to resection have been performed to achieve the cure. The purpose of this retrospective study was to investigate the recurrence rate of odontogenic keratocysts (OKCs) treated by enucleation and peripheral ostectomy. Material and Methods An electronic search of the database of the Hacettepe University, Faculty of Medicine, Department of Pathology, was undertaken to identify patients histologically diagnosed with OKCs treated at Department of Oral and Maxillofacial Surgery between 2001 and 2015. Results In total, 81 patients were studied. T…
Conservative surgery of renal cell carcinoma.
1986
Abstract From 1967 to 1985 conservative surgery (enucleation, n = 49; partial resection, n = 7) was performed for renal tumors in 57 patients (age 31-77, mean 54.8 years). Imperative indications for conservative surgery (n = 29) were chronic renal failure, benign pathology of contralateral kidney, functional or anatomical solitary kidney, and bilateral tumors. Elective conservative surgery (n = 28) was done for small, peripherally located lesions, in cases of uncertain malignancy and in one tumor detected by chance during stone surgery. Tumors removed for imperative indications were 2-11 cm (mean 5.8 cm) in size. In the elective group, tumor size ranged from 1 to 7 cm (mean 3.3 cm). Follow-…
Conservative surgery of renal cell tumors in 140 patients: 21 years of experience.
1992
Operative method, course and complications were analyzed retrospectively in 140 patients who underwent a conservative operation for renal tumor between June 1969 and December 1990. In 53 patients (20 women and 33 men, mean age 61.2 years, range 38 to 77 years, with 49 renal cell carcinomas and 4 benign renal tumors) there was an imperative indication for an organ preserving operation because nephrectomy would have made dialysis obligatory. In 87 patients (29 women and 58 men, mean age 53.7 years, range 27 to 74 years, with 72 renal cell carcinomas and 15 benign renal tumors) the tumor was conservatively resected in the presence of a normal contralateral unit (elective indication) and 68 of …
NEPHRON SPARING SURGERY FOR CENTRAL RENAL TUMORS: EXPERIENCE WITH 33 CASES
2000
Purpose: Nephron sparing surgery is standard treatment for small, peripherally located renal cell carcinoma. In patients with a solitary kidney, bilateral tumors or impaired renal function nephron sparing surgery provides the only option to nephrectomy and subsequent hemodialysis or transplantation. We retrospectively investigated the value of nephron sparing surgery for centrally located renal cell carcinoma. Materials and Methods: Between 1969 and 1997, 311 renal tumor enucleations were performed at our institution. The tumor was centrally located in 33 cases. The indication for enucleation was elective in 7 cases and imperative in 26, including bilateral tumor in 16 (metachronous in 9 an…
