Age-related and gender-related differences between human vertebral and iliac crest bone--a histomorphometric study on the population of the Mediterranean Coast of Croatia.

In this study, osseous tissue was examined in normal adult population that has inhabited areas by the Croatian Adriatic Sea. The most of such studies have shown that women are prone to lose bone connectedness, while men are predisposed to be a stronger constitution and they start with greater bone mass, though. Bone samples from two different anatomic sites were analyzed. The crista iliaca and the lumbar vertebra represent functionally different organs too. We wanted to consider weather the same age- and gender-related changes affect these two organs due to normal aging. Static histomorphometry was used to quantify involution changes in the trabecular bone. Results showed that involution process more severely affects women than men. Age-related structural changes were more prominent in lumbar vertebra than in iliac crest bone. Severe structural changes in lumbar vertebra could subsequently lead to a dysfunctional and deformed vertebral column. Therefore, iliac crest bone biopsies could hardly explain involution process that affects lumbar spine.

Prevalence of scoliosis in school-children from Mostar, Bosnia and Herzegovina.

In the school-year 2002/2003 a prospective epidemiological study was performed with the aim of evaluating the prevalence and distribution of scoliosis in the population of schoolchildren from Mostar, Bosnia and Herzegovina. The general check-up of primary-school children covered a total of 2,517 children aged 7-14. The children in which at least one positive symptom of scoliosis was found were directed to undergo orthopedic examination and--if indicated--radiography. Incorrect posture was noted in 33.4% of children, and 11.8% of children were sent to orthopedic specialist examination. The prevalence of structural scoliosis amounted to 3.1%, with the spine curvature threshold being 10 degrees. In eight children (0.32%; 1 boy and 7 girls) a curvature of 20 degrees or more was diagnosed. The most common type of curvature was the thoracal (39%) and the thoraco-lumbar (39%) while 14 children had a double curvature (17.8%). A scoliosis was detected due to here performed check-up in 83.5% of children with scoliosis. No case of serious spine deformity (45 degree or more) was recorded, due to regular general check-ups taking place biannually in this population.

[Hospital outcome in acute coronary syndrome in the period 1987-2001 in West-Herzegovina canton--retrospective study].

Objective of the study is to show prevalence of hospital mortality of acute coronary syndrome in pre-war (1987-1991), war (1992-1996) and after war period (1997-2001) among inhabitants of West-Herzegovina canton living in the following municipalities: Siroki Brijeg, Posusje, Grude and Ljubuski (88,992 inhabitants). Collected were data on patients who were admitted in the hospital due to acute coronar syndrome (category I 20, 21, 22- X revision, ICD) in the above period in Mostar. Data were analyzed in regard to sex, age and disease output. Hospital morality in 15 year period for both sex were 15.0 %, men 12.1 %, and women 20.2 %. Statistically it was not found significant differences in the period 1987-2001 in regards to total hospital mortality of men and women and separate hospital mortality of men. Differences were found in women where considerable larger number was in pre-war and post-war period in comparison with war period. The largest hospital mortality was in total and for women in the pre-war period and for men was during the war period. The smallest hospital mortality was in total and for women during the war and for men in pre-war period. We find that lower hospital mortality in women was caused by lower hospital admission because of war time and problems with transport and that larger number of women deceased before admission to the hospital.

Cerebrovascular insult hospital cases in the Clinical Hospital Mostar (Bosnia and Herzegovina) from 1999 to 2003--an example of an institutional register.

The analysis of a cerebro-vascular insult hospitalized cases in the Clinical Hospital Mostar as a retrospective epidemiological study was done in the Clinical Hospital Mostar for the period from 1999 to 2003. The major source of data was medical documentation of this hospital (an institutional register), the only hospital for the treatments of 457,491 inhabitants who gravitate by a health insurance for the treatment in this hospital. The study included a total of 1,555 cerebro-vascular insult cases treated in the Clinical Hospital Mostar Among them 727 (46.8%) were male patients, while 828 (53.2%) cases were female. The majority of the cases were above 50 years of life. Majority of treated female patients were older than 61 (45.6% of all cases), as well as among male patients (31.3%). The least number of cases was under 41 years in both groups (1.2%). Prevalence of risk factors was 2,035 cases (74%). During the same period risk factors research for entire Federation of Bosnia and Herzegovina (FBiH) was performed on the sample of 2,750 national insurance holders, out of which 852 gravitate for treatment in CB Mostar. Out of them 1.7% was found to suffer of cerebro vascular insult.

Pulmonary function in persons who are professionally exposed to formaldehyde fumes.

The present study examines long-term effects of occupational exposure to formaldehyde fumes on lung function. Forced spirometry and diffusing lung capacity were measured in 16 health-service professionals (8 medical doctors and 8 laboratory technicians) working at the pathoanatomic laboratory for at least 4 years with daily exposure 8 +/- 1 hours. Control group employed 16 males, which were matched by age and stature to members of the exposed group. Only non-smokers were included in the study. Spirometric parameters in study participants exposed to formaldehyde fumes compared to control group were not significantly different indicating absence of restrictive and/or obstructive deterioration of lung function in exposed group. The only parameter differing in two groups was blood volume of pulmonary capillaries (Vc') which was significantly larger in a group exposed to formaldehyde fumes. The possibility that the hyperemic lung reaction is the consequence of the exposure to formaldehyde fumes should be further explored.

Lung function changes in pleural asbestosis.

The aim of this study was to examine the relationship between radiographically detectable pleural changes and lung function in pleural asbestosis. One hundred and twenty chrysotile asbestos-exposed workers were enrolled in this retrospective study. For each examinee the length of asbestos exposure and the degree of dust cover at the workplace were assessed as well as the radiological and functional tests has been performed. The examinees were divided into two groups based on radiologically detectable changes: a) group with pleural changes (29%) and b) group without perceived pleural changes (71%). The obtained results indicate association between the length of asbestos exposure, pleural changes and the impairment of lung function.

[Use of TENS in patients with rheumatoid arthritis].

The patients with rheumatoid arthritis of the fourth grade have used the whole basic therapy and, of course, antirheumatic therapy with all their positive and negative effects. We have applied and analysed the application of analgetic physical therapy with TENS (Transcutaneous Electrical Nerve Stimulation). TENS appeared to be a perfect substitution for nonsteroid antirheumatics and analgetics. Its easy application, the possibility of using at home and practically non-existent contraindications give him the priority at pain relief for rheumatoid arthritis of the fourth grade.

[Standardization of diagnosis and therapy in whiplash injuries of the cervical vertebrae].

In this work it is shown a standard diagnostic and therapeutic approach with the patient with stinging neck injury with goal to achieve a protocol for grouping injuries in those categories according to which we will proceed in further diagnostic and treatment, and letting out diagnoses as soon as possible in time period within the rational apply of available diagnostic procedures. The result of installing standardized protocol is the connection of the standard in diagnostic and therapy with safer triage of injured, standard therapy and getting precious time which we could use in treating a patient which will be helped with the treatment itself. In further diagnostic search it is out of most important question to define biomechanical limit of non dangerous in the stinging neck injury which will help to make a line between real injuries and renthal demands. In the therapeutic meaning, the injured patient is to be returned into the activity as soon as possible and certainly not after all the results have been back to normal.

[Compression fracture of a fragile lumbar vertebrae as a cause of low back pain].

The patient felt sharp back lumbal pain while lifting heavy object in flexion position of the back. Rtg showed compressive fracture of L2. MRI showed secondary posttraumatic edema around compressive fracture of the body of L2. The compressive fracture was caused by intracorporal haemangiome of L2. After six months we had spontaneous sanation of heamgiome. Regarding to the therapy only electromagnetotherapy was used as well as programme of kinezitherapy given according to the condition of the body of L2.
