Comparative analysis of the quality of life regarding patients who underwent hip replacement in public versus private hospitals in Hungary.

The study aimed to investigate the impact of hip replacement surgery on the quality of life and to compare the outcomes by sociodemographic and surgical data in Hungarian public and private hospitals. Patients were selected at the Department of Orthopaedics (Clinical Centre, University of Pécs) and at the Da Vinci Private Clinic in Pécs. Patients completed the SF-36 and Oxford Hip Score (OHS) questionnaires before the surgery, 6 weeks and 3 months later.

[Investigation of the short-term quality of life and socio-demographic factors of patients undergoing total hip arthroplasty].

Introduction: Among the health needs related to an aging society, the increase in the number of hip replacement surgeries stands out. Objective: The study aimed to examine the socio-demographic data of patients operated in the private and state health care with total hip arthroplasty in different approaches, and to compare their quality of life before and after surgery. Data and methods: Patients were selected by simple convenience sampling technique at the Department of Orthopedics, Clinical Centre of the University of Pecs and at the Da Vinci Private Clinic in Pecs.

Expression of NFkB1, GADD45A and JNK1 in salivary gland carcinomas of different histotypes.

The class of salivary gland tumours is very heterogenous, both in a histopathological and clinical sense. Since they are uncommon lesions, their clinical management is still problematic. Molecular mechanisms underlying the development of these cancer types may be fundamental for the diagnosis, treatment and prognosis of this disease.

Changes in expression of oncogenes and TP53 tumour suppressor gene as biomarkers in head and neck cancers.

Despite modern diagnostic procedures and up-to-date therapy, the survival of head and neck tumour patients is unfavourable. This can be explained by several factors, one of which is the late recognition of the tumour. This study related to the changes in expression of the c-myc and Ha-ras oncogenes and the p53 tumour suppressor gene as biomarkers in head and neck cancer cases.

Association between XRCC1 polymorphisms and head and neck cancer in a Hungarian population.

Background: Head and neck cancer is a significant current health problem in Hungary because the mortality of this cancer has increased by 387% in the last thirty-two years. Because of the important role of the XRCC1 gene in DNA repair, we wanted to test the effects of the Arg194Trp and Arg399Gln polymorphisms of XRCC1 on the clinical outcome of head and neck cancer.

Patients And Methods: A polymerase chain reaction-restriction fragment lenght polmorphism (PCR-RFLP) method was used.

Early modification of c-myc, Ha-ras and p53 expressions by chemical carcinogens (DMBA, MNU).

7,12-Dimethylbenz[a]anthracene (DMBA) and N-methyl-N-nitrosourea (MNU) are important environmental carcinogens. Their different biological effects were examined in CBA/Ca H-2(K) haplotype inbred mice on the gene expression of c-myc, Ha-ras and p53 through a 24 hour period. Elevated expression of c-myc and Ha-ras genes was found in the spleen, lung, thymus and lymph nodes 6 and 12 hours after DMBA treatment and in the lung and thymus 3 hours after MNU treatment.

Early modification of c-myc, Ha-ras and p53 expressions by N-methyl-N-nitrosourea.

Methylnitrosourea (MNU) is a well-known pluripotent direct-acting carcinogen. Formation of MNU following incubation of various meats with additional nitrite under in vitro acidic conditions is possible. It is possible that many species, including humans, are exposed to carcinogenic MNU, generated in their alimentary tract.

Primary carcinoma of the frontal sinus: a case report and a review of literature.

Paranasal sinus cancer is rather rare, with an incidence of less than 1 per 100,000 per year, the frontal sinus being the primary site in only 0.3%. Following clinical and radiological examinations, the diagnosis often remains elusive, the condition mistakenly being considered to involve mucocele, pyocele or osteomyelitis.

Tracheal ceramic rings for tracheomalacia: a review after 17 years.

Background: Despite different support techniques, the surgical management of tracheomalacia is still a challenging problem. Satisfactory results after internal stenting are above 80%, whereas, when performing external stenting using biocompatible ceramic rings, results are reported at over 90%.

Objective: The purpose of this study was to examine the efficiency of surgical treatment in patients with segmentary tracheomalacia using external ceramic ring grafts.
