The Detection of Premalignant and Malignant Gastric Lesions by Conventional Endoscopy in a General Population Sample

Background and Aims: The identification of patients with premalignant lesions and endoscopic surveillance could improve the early detection of gastric cancer, with better therapy and prognosis. We performed conventional endoscopy with biopsies to identify the incidence rates of premalignant and malignant gastric lesions and the risk of patients for this pathology.
Methods: A total of 1651 patients were investigated with conventional endoscopy. We took biopsies from 1493 patients. Biopsy specimens were analyzed for gastric inflammation, atrophy, intestinal metaplasia, dysplasia and neoplasia.
Results: We demonstrated that major symptoms had a sensitivity of 95.2%, and a specificity of 54.5% for the detection of gastric neoplasia, with a sensitivity of 61.6% and a specificity of 57.2% for the detection of premalignant lesions. We showed the risk of patients over 45 years, with major or minor symptoms, for premalignant and malignant gastric lesions (p < 0.001; RR = 3.34; 95%CI: 2.41–4.61). We emphasized the importance of histological evaluation by biopsies of entire gastric mucosa in case of polyps, ulcers, gastric atrophy detection or remnant stomach, for the evaluation of premalignant lesions (p < 0.,05). We showed that the prevalence of premalignant lesions increased with age and the presence of Hp infection. We demonstrated the risk of the inflammation in the gastric body for premalignant lesions.
Conclusions: The patient’s symptoms were not predictive of endoscopic and histologic findings. Not only symptoms, but also the age, the presence of Helicobacter pylori infection, the histological detection of the extent and location of gastric inflammation and premalignant lesions define the risk for the dyspeptic patients.

Tumors of the Oro-Facial System

The increasing number of malignant cases in the oro-facial area represents by their increasing number lately a new problem regarding the treatment and diagnosis. This cases present an increased difficulty of diagnostic and treatment, because they are usually diagnosticated in lately stages. Patients are often unaware of the gravity of their situation due to the lack of specific or almost absent symptomatology.
The incriminated factors and co-factors incriminated in the development of the malignant manifestations are of multiple origins: use of tobacco products, especially associated to alcohol abuse, chronical topic irritation of the oral mucosa, genetic predisposition or some types of viruses (human papilloma virus type 16 and 18 and herpes virus). Also factors like: environmental modifications, age, alimentation or pharmaceutical drug usage can be incriminated for the increasing pathology of the last decades, especially in well developed countries both from Europe and North America.
Our presentation is based on the case of a 61 years old male, showing almost the typical premises of a malignant pathology starting from the evolution of the oral lesion and the general and dental pathology status with the correlation of the objective and subjective examination.
The lesion usually benefits of surgical treatment, followed by radiotherapy and oro-facial reconstruction, that can imply both plastic surgery and prosthetic rehabilitation, as was the case of our patient. Of most importance remains the moment of the prosthetic treatment and its correlation with radiotherapy, regarding the tissue modification that irradiation has on this level.

Cytological, Histological Correlations and Human Papillomavirus Testing in the Diagnosis of Cervical Intraepithelial Neoplasia

Introduction: Persistent infection with high risk Papillomavirus (HR HPV) is the main risk factor for cervical cancer. Usually there is a period of approximately 10 years since someone gets infected with HPV till the incidence of an invasive cancer. The slow evolution of precancerous lesions allows their detection before the invasive stage. The objective of this study is to evaluate correlations among cytology, colposcopically guided biopsy and HPV testing, HR HPV prevalence and the reliability of cervical-uterine smears as screening method.
Material and method: The study comprises a number of 64 patients who underwent colposcopy, cytodiagnosis and biopsy examinations during January 2010 – December 2011 at Saint Die Hospital (France). Testing for HR HPV was performed especially in case of ASCUS Pap smears.
Results: ASCUS results of cervical-uterine smears corresponded to histological diagnosis of normal aspect and benign lesions in 60% of the cases, in 26.66% of cases with low grade malignant lesions and in 13.33% of the cases with high grade malignant lesions. HR HPV testing was positive especially in patients younger than 30 years (93.33% of patients who performed the HR HPV test), for patients between 30 and 50 years HR HPV was present in 80% of tested patients and for patients over 50 years was present only in 20% of the cases. Neither of the patients who tested negative for HR HPV presented high grade malignant lesions as a result of the biopsy test.
Conclusions: There is a direct correlation between the presence of HPV and grade of malignancy, thus all patients presenting high grade malignant lesions tested positive for HR HPV. HPV testing should not be performed in patients with LSIL results when sampling cervical-uterine smears, because the HPV prevalence is highly increased and a positive HR HPV test result would only create panic in young patients.

Clinical Features and Histopathological Spectrum in Adolescent Onset Nephrotic Syndrome in a Romanian Children Population

DOI: 10.2478/amma-2014-0032

Objectives of study: The adolescent population signifies the transitory period where the frequent occurrence of different histopathological lesions in patients with nephrotic syndrome (NS) is different from that seen in young children as well as that seen in adults. This study aimed to analyze the clinical features and histopathological spectrum of adolescent-onset NS. Material and methods: We retrospectively evaluated clinical features, biochemical investigations and histopathology of 103 children with idiopathic NS referred to the Pediatric Department, County Hospital of Târgu-Mureş. Fourteen patients with congenital-, infantil- and secondary NS were excluded from this study. Results: The patients were divided into 2 groups: in group A we included 69 patients diagnosed with NS diagnosed before 10 years-old, with a median age of 3.76±1.96 years, majority males (59.42%) and presenting the pure form of NS. On the other hand, in group B we included 20 adolescents having the median age at the onset of the disease 13.61±2.18 years, with equal distribution of the sexes and presenting the impure form in 65% of cases. The majority of the patients in both groups (68.11% and 70% respectively) responded to steroid therapy. The commonest histopathological subtype in both groups was focal segmental glomerulosclerosis. Conclusions: The incidence of nephrotic syndrome has increased in the last years. The impure form of NS is more frequent in the adolescents than in younger patients. Adolescents with impure and steroid-resistant NS at presentation have other lesions than minimal change disease. The early genetic diagnosis in NS is important for proper clinical management of the patients, prognosis and genetic counseling of the families.

The Management of the Patient with Elevated Prostate Specific Antigen and a Negative Initial Prostate Biopsy

DOI: 10.1515/amma-2015-0021

Background: The prostate cancer (PCa) is the second  most  common cancer amongst men. An elevated prostate specific antigen (PSA) level can lead to PCa suspition, thus the confirmation has to be a histopathological one. However, not all increased PSA level means prostate cancer.
Material and Method: This retrospective study presents the results of 422 ultrasound guided prostate biopsy (PB) performed at the Clinic of Urology Târgu- Mureş, between 2011-2012. Inclusion criteria: patients with at least one negative PB and an elevated value of PSA.
Results: In a two year period, from the total of 422 PB (100%), in 179 (42.42%) patients the histopathological result was “negative”. In 154 (86%) of cases ultrasound guided biopsies were performed, mostly with an initial 6 core (98- 54.74% of patients). Average PSA level was 13.45 ng/ml (0.49-100 ng/ml), the histological findings confirmed PCa in 52.58% cases, normal prostatic tissue in 141 cases (78.77%), atypical small acinar proliferation in 12 patients (6.70%), prostate atrophy in 11 males (6.14%), benign prostatic hyperplasia in 10 cases (5.59%) and prostatitis in 5 cases (2.80%). In 30 cases (16.75%) rebiopsy was performed with a number of 10- 12 cores.
Conclusions: In order to increase PCa detection we should perform more cores during PB. In „negative” histopathological cases PSA should be monitorised and the biopsy should be repeated after 6 to 8 weeks from the initial biopsy. Patient’s compliance plays a vital role in the follow-up of the procedure.
Conclusions: ANG-2 serum levels were elevated in sepsis, being well correlated with PCT values and prognostic scores. ANG-2 should be considered as a useful biomarker for the diagnosis and the prognosis of this pathology.
