Background: Osteochondroma is the most common tumor of bone, accounting for approximately one third of benign lesions in the skeleton is a broad (sessile) or narrow (pedunculated) skeletal protrusion comprised of marrow and cortical bone. Although it is benign, its biological behavior still has a malignant potential. Chondrosarcoma arising in osteochondroma has been recognized for many years. Osteochondromas might occur on any bone preformed in cartilage, they were especially seen on the long bones of the extremities, predominantly around the knee. In fact, the lower limb seemed to be at a higher risk of the tumor than the upper limb on the top two locations: distal part of the femur and proximal part of the tibia, however, the proximal humerus ranked the third place for solitary osteochondroma while the proximal fibula for multiples osteochondromas. Methods and Findings: A total of 20 skeletons and 18 cadavers of both sex, 16 males and 2 females, with different age groups were used, this study was carried out by routine dissection classes for undergraduate medical student´s in the Morphology Laboratory of the University of Pamplona during the years 2013-2016. In only one sample was found the presence of osteochondroma. The measurement of the osseous mass was of 7 x 3.5 x 1.5 cm, attached to the posterolateral aspect of the middle third of the femur. Conclusions: Osteochondroma is generally asymptomatic or discovered accidentally, but it can cause different symptoms depending on site of occurrence local swelling, bony deformities, fracture, bursa formation, arthritis and impingement on adjacent tendons, vascular or neurologic compromise, and dislocation The importance of correct treatment and follow-up of large osteochondromas to avoid complications such as further damage to neighboring neurovascular structures, and potential malignant degeneration. The present study describe a rare location from an osteochondroma in the femur diaphysis.

Starting A Business

AbstractEntrepreneurship understood as a manifestation of economic activity is an issue widely discussed in literature, especially in the field of economics. Today, a large part of society is involved in establishing and running a business, hence the shaping of entrepreneurial behaviors gains importance among all age groups, especially young people. The main objective of the conducted research was to examine the interest in starting their own business by students and to verify whether the direction of their studies or role in the group affects the students’ willingness to start a business and whether a family member runs a business influences this interest and moreover, whether capital and the idea are the two main criteria conditioning the decision.. The conclusions were based on a study, i.e. (mainly) the cross-analysis of data collected as part of a survey conducted among students of the University of Information Technology and Management in Rzeszów.

Vertebral Involvement

Chondrosarcoma is the third most common primary malignant bone tumor after osteosarcoma and Ewing’s sarcoma. Clear cell chondrosarcoma is a rare subtype variant of chondrosarcoma, most commonly encountered in the proximal part of the femur or humerus. Vertebral involvement is exceedingly rare and shows a predilection for the thoracic spine. We report the case of a woman with clear cell chondrosarcoma of the thoracic spine, which has been surgically excised, and review the pertinent literature (PubMed). Although it has a reasonably benign biological behavior, clear cell chondrosarcoma needs to be treated as a malignancy. The best treatment for spinal chondrosarcoma is surgery. It should be promptly and adequately resected. Gross-total resection should be the ultimate surgical goal. Radiation therapy should also be considered, especially in the case of subtotal resection or inoperable lesions. In conclusion, it is important to keep in mind this entity in the differential diagnosis of spinal tumors, in order to optimize treatment planning. With adequate treatment, local recurrence rates as low as 20% can be achieved.

Comprehensive Study

Abdominal pain is one of the most common reasons for visit to the emergency room. Acute appendicitis is the commonest cause. An accurate diagnosis is essential for the correct treatment, which in many cases will prevent the death of the patient. Mainstay of diagnosis is history and physical examination. If this information is inadequate to establish a diagnosis and urgent or immediate operation is unnecessary, the periodic re-examination helps document the progression of the disease and often avoids unnecessary surgical intervention. Today the combination of improved diagnostic procedures, antibiotic and better anaesthesia and preoperative and postoperative patient care has led to a decrease in morbidity and mortality of patients with acute abdomen. The objective of this study was to determine the various causes of nontraumatic acute abdominal emergencies, their incidence, management and mortality in both sexes and all age groups >12 years age.

Background: Vitamin D deficiency is today acknowledged as a pandemic. Vitamin D deficiency and insufficiency are associated with many chronic diseases, including common cancers, cardiovascular diseases, metabolic syndrome, and infectious and autoimmune diseases.Objective: This study aims to investigate the relationship between the cotinine level in urine and Vitamin D.Methods: This study employed a descriptive and relational screening design.  It was conducted with 74 smoking university students between January 2019 and March 2020. Data were collected through socio-demographic form and Fagerstrom test for nicotine dependence. Besides, the participating students’ blood and urine samples were taken in a suitable environment.Results: The average age of the participating students was 21.50±2.09. Of all the students, 71.6% were males, 62.2% were exposed to the sun between 12 p.m. and 2 p.m., and the average number of cigarettes smoked daily was 13.52±8.22. The average Vitamin D level in blood was 32.4±15.3 (ng/mL), and the average cotinine level in urine was 1.60 ± .32 (ng/L). No statistically significant relationships were found between the Vitamin D level and the cotinine level (p<0.05).Conclusion: Smoking causes diseases and death in many people, and it is a changeable risk factor.  Nursing practices on the struggle against smoking are effective. No significant relationships were found between the Vitamin D level in blood and cotinine level in urine. Similar studies are recommended to be conducted with larger groups and participants from different age groups.

The “Veneto Cancer Registry” records melanoma as the most common cancer diagnosed in males and the third common cancer in females under 50 years of age in the Veneto Region (Italy). While melanoma is rare in children, it has greater incidence in adolescents and young adults (AYA), but literature offers only few studies specifically focused on AYA melanoma. The aim of this study was to describe the characteristics, surgical treatment, and prognosis of a cohort of AYA melanoma in order to contribute to the investigation of this malignancy and provide better patient care. This retrospective cohort study included 2,752 Caucasian patients (702 AYA and 2,050 non-AYA patients) from the Veneto Region who were over 15 years of age at diagnosis, and who received diagnosis and/or treatment from our institutions between 1998 and 2014. Patients were divided in adolescents and youth (15-25 years), young adults (26-39 years) and adults (more than 39 years) for the analysis. We found statistically significant differences in gender, primary site, Breslow thickness, ulceration, pathologic TNM classification (pTNM) stage and tumor subtype among the age groups. Disease-specific survival and disease-free survival were also different among the age groups. Our findings suggest that the biological behavior of melanoma in young people is different to that in adults, but not such as to represent a distinct pathological entity. Additional and larger prospective studies should be performed to better evaluate potential biological and cancer-specific differences between AYAs and the adult melanoma population.

ObjectiveThe objective of this study was to validate the computerized Symbol Digit Modalities Test (c-SDMT) in a Swiss pediatric cohort, in comparing the Swiss sample to the Canadian norms. Secondly, we evaluated sex effects, age-effects, and test–retest reliability of the c-SDMT in comparison to values obtained for the paper and pencil version of the Symbol Digit Modalities Test (SDMT).MethodsThis longitudinal observational study was conducted in a single-center setting at the University Children’s Hospital of Bern. Our cohort consisted of 86 children (45 male and 41 female) aged from 8 to 16 years. The cohort included both healthy participants (n = 38) and patients (n = 48) hospitalized for a non-neurological disease. Forty eight participants were assessed during two testing sessions with the SDMT and the c-SDMT.ResultsTest–retest reliability was high in both tests (SDMT: ICC = 0.89, c-SDMT: ICC = 0.90). A reliable change index was calculated for the SDMT (RCIp = −3.18, 14.01) and the c-SDMT (RCIp = −5.45, 1.46) corrected for practice effects. While a significant age effect on information processing speed was observed, no such effect was found for sex. When data on the c-SDMT performance of the Swiss cohort was compared with that from a Canadian cohort, no significant difference was found for the mean time per trial in any age group. Norm values for age groups between 8 and 16 years in the Swiss cohort were established.ConclusionNorms for the c-SDMT between the Swiss and the Canadian cohort were comparable. The c-SDMT is a valid alternative to the SDMT. It is a feasible and easy to administer bedside tool due to high reliability and the lack of motor demands.

Background: Brachial plexus variations are not rare. Variations in its terminal branches in the arm or forearm are frequently reported. Communications between branches of the brachial plexus are also not uncommon findings; however there is very little mention of communication between the radial and ulnar nerves in the literature. In view of this significance is performed this study with the purpose to determine any communications of radial nerve with neighboring peripheral nerves at level of axilla, arm, forearm. Methods and Findings: A total of 17 cadavers with different age groups were used for this study. The upper limbs region (34 sides) were dissected carefully and photographed in the Morphology Laboratory at the University of Pamplona. Of the 34 upper limbs studied 33 showed normal morphology, the course and branching patterns of the nerves was normal (97.06%). In 1 specimen in the left forearm (2.94%), the radial and ulnar nerves were dissected and communicating branches were observed originating near the upper third in the posterior aspect of the forearm traveling from the ulnar to the radial nerve. The communicating branch was approximately 5.84 cm long and 1.73 mm in diameter. This anastomotic branch is an unusual anastomosis, no described in the literature between radial and ulnar nerve in forearm. Knowledge on the variant pattern of peripheral nerves is imperative not only for the surgeons, but also for the radiologists during image technology and MRI interpretations and for the anesthesiologists before administering anesthetic agents thus in diagnostic approaches.   Conclusions: Lack of understanding of these variations can also confound the assessment of the severity of nerve injury as well as recovery. Awareness of such anatomical variations is very important in order to proper diagnosis of sensorimotor symptoms.

Objective. The aim of this study was to investigate the tongue cleaning habits using toothbrushes among outpatients of the University of Fukui Hospital and a private hospital in Fukui Prefecture. Methods. We administered a questionnaire survey to volunteers detailing tongue cleaning habits using toothbrushes. The content of the questions in this survey were as follows: gender, age, frequency of tongue cleaning, portion of tongue cleaning, and purposes of tongue cleaning. Results. We had 1,014 volunteers of various ages participating in this study. Regarding the frequency of tongue cleaning, 187 (18.4%) of all participants replied, “Every day”, and 346 (34.1%) replied, “Sometimes”. Regarding tongue cleaning of the 533 participants with active tongue cleaning habits, 242 (45.4%) participants replied, “The center of the dorsum of the tongue”, and 274 (51.4%) replied, “The entire tongue”. When analyzing the purpose of tongue cleaning, 346 (64.9%) participants replied, “To remove the tongue stain”, 192 (36.0%) participants replied, “To remove the tongue coating”, and 240 (45.0%) participants replied, “To manage halitosis”. Conclusions. This study clarified that a wide range of age groups in the nonhospitalized general public practiced tongue cleaning habits using a toothbrush for various purposes.
