The authors presented 4 cases of primary malignant neoplasm of the intestine caused by small intestine obstruction. These patients underwent emergency surgery. In all cases, a segmental resection of the intestine was performed. There were two cases of adenocarcinoma and two cases of carcinoid. Three patients were compl…

A man had left-sided atypical clusterlike headache for 9 years before he developed symptoms and signs consistent with acromegaly. Preoperative evaluation revealed raised levels of somatomedin C and growth hormone. An MR indicated a left-sided intrasellar mass measuring 8 x 7.5 x 10 mm. He underwent surgery and microsco…

In this preliminary report the divergence times for the major primate groups are given, calculated from a study by comparative determinant analysis of 69 proteins (equaling 0.1% of the whole genetic information). With an origin of the primate order set at 80 million years before present, the ages of the last common anc…

OBJECTIVE: To investigate the effectiveness of tunnel osteogenesis technique combined with locking plate in the treatment of aseptic non-hypertrophic nonunion of femoral shaft. METHODS: The clinical data of 23 cases of aseptic non-hypertrophic nonunion of femoral shaft treated with tunnel osteogenesis technique combin…

PURPOSE: To investigate the aseptic survival of 1.5-stage exchange arthroplasty for periprosthetic joint infection (PJI) after total knee arthroplasty (TKA). METHODS: Eighty-eight cases of 1.5-stage exchange arthroplasty for PJI without reinfection were retrospectively analysed. The autoclaved femoral component and ne…

Osteosarcoma is the most frequent primary osteal tumor in children. Our study evaluates morphological aspects of osteosarcomas during last 20 years. We present the results of study that includes 32 cases of classical osteosarcomas that had been diagnosed and treated at the "Sf. Maria" Hospital from Iasi (Romania). The…

The interaction between step kinematics and stance kinetics determines sprint velocity. However, the influence that stance kinetics has on effective acceleration in field sport athletes requires clarification. About 25 men (age = 22.4 ± 3.2 years; mass = 82.8 ± 7.2 kg; height = 1.81 ± 0.07 m) completed t…

PURPOSE: To evaluate the predictive value of the rhTSH thyroglobulin stimulation test (rhTSH-Tg) compared to basal high-sensitive thyroglobulin (hs-Tg) under TSH suppressive therapy at 12 months after the completion of initial treatment to predict the long-term response and Dynamic Risk Stratification (DRS) at the last…

This study aimed to analyze the behavior change and related factors regarding HIV/STD epidemics among female sex workers (FSWs) in Qingdao city.According to the requirements set by the"National HIV/AIDS sentinel surveillance program", information on demographics, sexual and drug use behaviors, and HIV-related services…

The authors aimed to assess the impact of a routine ultrasound examination performed between 10 and 13 weeks of pregnancy. During a thirty month period, 778 ultrasound examinations between 10 and 13 weeks of pregnancy were performed, in women referred to our hospital. Transvaginal ultrasound was systematically adopted…

The development at a university hospital of radical surgery for exocrine pancreatic cancer has been studied for the time period 1958-1989. It was found that the number of operations per year increased gradually, being 6.6/year during the last 5 years, giving a resection rate of 15%. The resection rate did not change du…

BACKGROUND: Orofacial clefts are common and have a great medical and social importance. The Latin American Study of Congenital Malformations (ECLAMC), has maintained an epidemiological surveillance of congenital malformations since 1969, allowing the evaluation of trends in the prevalence of malformations. AIM: To eva…

Genetic data organized in the form of genealogies can provide much information regarding the history and genetic structure of human populations. A large proportion of the population of Latin America is organized in small rural semi-isolated communities, with little immigration, and until the last 50-100 years, little e…

Subpolar North Atlantic proxy records document millennial-scale climate variations 500,000 to 340,000 years ago. The cycles have an approximately constant pacing that is similar to that documented for the last glacial cycle. These findings suggest that such climate variations are inherent to the late Pleistocene, regar…

A quality-control project covering 56 pieces of mammographic equipment was carried out in Finland. The evaluation was based on the determination of contrast, film optical density, resolution, focus size, tube voltage, exposure time, half-value thickness, reproducibility and linearity of exposure, surface and exit dose,…

BACKGROUND AND OBJECTIVE: We describe 6 cases of secondary osteoporosis due to systemic mastocytosis diagnosed in the last 6 years. RESULTS: Three females and 3 males, age range: 47-66 years, diagnosed with osteoporosis were subsequently diagnosed with systemic mastocytosis. Diagnosis delay: 0.5-17 years. Cutaneous in…

In general, anastomotic recurrence of colorectal cancer occurs within 3 years after surgery. We encountered an extremely rare case of anastomotic recurrence over 20 years after surgery. A 70-year-old woman who had undergone low anterior resection for rectal cancer 22 years previously was admitted to the hospital becaus…

BACKGROUND: Pregnancy provides a special opportunity to improve cervical screening test (CST) uptake and reduce cervical cancer. Screening in Australia is free for Medicare-eligible women ≥ 25 years if performed 5-yearly, but not sooner. Either women's self-reported last CST date or the National Ca…

BACKGROUND: Healthy movement behaviours in early life promote better physical health and facilitate psychological development. Early childhood education (ECE) institutions provide opportunities for caregivers to improve children's movement behaviour practices, but little is known about the current status of movement be…

Techniques of localized hyperthermia have been developed these last years. Very superficial tumors may be heated by infra-red radiation, radiative diathermy at high frequencies (2450 MHz) or even by techniques of contact hyperthermia. Superficial tumors (some cm deep) may be heated by radiative diathermy at lower frequ…
