The aim of this study was to investigate whether there is any significant bone loss of the ulna and radius following acute tendon-artery-nerve clean-cut injuries at the wrist level which were repaired and rehabilitated by early passive mobilisation. Fifty-eight patients who underwent such operation were enrolled in this study. Patients in Group I ( n = 28) had primary tendon repairs alone, in Group II ( n = 15) primary tendon and nerve repairs and in Group III ( n = 15) primary tendon, nerve and artery repairs. Bone mineral density (BMD) measurements of the ulna and radius were obtained during the first week, the sixth week, the third month and the 12th month after operation. The results demonstrated that BMD decrease in the ulna was more common than in the radius. When compared with the first week BMD measurements, the highest reduction was seen in the sixth week in Group I and during the third month, when bone loss of both the radius and ulna was considerable in Group II. The bone loss in all groups and subgroups were found to have recovered at the 12th month measurements, except in the distal region of the ulna in Group I. This study suggests that passive immobilisation is deleterious in respect of demineralisation of the forearm bones.

Objective: the clinical value of spinal quantitative CT (sQCT) and the structural patterns of the vertebral bone were studied Material and Methods: sQCT was performed on 246 patients with a mean age of 57 years for whom conventional lateral radiographies of the thoracic and lumbar spine were available. All patients were suffering from back pain of unknown etiology. the bone mineral density (BMD) of the midvertebral section of 3 lumbar vertebral bodies was determined by means of single-energy-(SE)-weighted QCT (85 kV). Spongiosa architecture and density profile analyses were made in the axial images. This was contrasted to BMD values ascertained in SE QCT. the mean BMD was compared to the number of fractures and the patients were divided into three groups: group I — no fracture; group II — one fracture; and group III 1 fracture Results: the mean BMD was: 134.3 (74.1–187.5) mg hydroxyapatite (HA)/ml in group I; 79.6 (58.6–114.3) mg HA/ml in group II; and 52.4 (13.1–79.1)mg HA/ml in group III. A significant deterioration in spongiosa structure was found with increasing demineralization: strongly rarefied patterns predominated in the fracture groups II and III Conclusion: sQCT provides a good risk assessment of the occurrence of vertebral body insufficiency fractures

Objective. To assess androgen secretion and its possible effect on pregnancy in women with threatened miscarriage in the first trimester. Patients and methods. This prospective observational study included 120 pregnant women divided into four groups. Group I comprised 32 patients with threatened miscarriage and hyperandrogenism who received corticosteroids; Group II was composed of 28 patients with threatened miscarriage and hyperandrogenism who did not receive corticosteroids; Group III included 30 patients with threatened miscarriage and no hyperandrogenism; and Group IV comprised 30 women with normal pregnancy. Serum levels of dehydroepiandrosterone sulfate (DHEA-S), 17-hydroxyprogesterone (17-OHP), and total testosterone were measured on the following weeks of gestation: 5–8, 9–12, 13–18, 19–24, and 25–32. We also evaluated clinical outcomes of pregnancy. Results. We observed no significant differences in 17-ОНР and DHEA-S secretion between women from Group III and controls. Patients from Group II demonstrated higher hormone levels than controls; however, their dynamics of 17-ОНР and testosterone secretion was similar to that in women without hyperandrogenism, so their DHEA-S levels decreased and reached control values by the third trimester. Corticosteroids reduced 17-ONR secretion in the second and third trimesters and DHEA-S secretion in the third trimester. Women receiving corticosteroids demonstrated the poorest clinical pregnancy outcomes. Conclusion. Hyperandrogenism should be considered as one of the risk factors for poor pregnancy outcomes. Administration of corticosteroids to reduce androgen levels impairs normal dynamics of their secretion, does not improve pregnancy outcomes, and is potentially harmful; therefore, these drugs should not be used for such purposes. Key words: pregnancy, hyperandrogenism, corticosteroid therapy, pregnancy outcomes, pregnancy loss, androgen secretion, threatened miscarriage

Purpose. Osteoporosis is a progressive systematic skeletal illness characterized by low bone mineral density and susceptibility to fracture caused by bone resorption. Aim of the Study. This study intended to evaluate the possible role of emdogain in combination with calcitonin on the healing of surgically induced mandibular defects performed on osteoporotic rats. Materials and Methods. Forty healthy female white albino rats were included in this study and divided into four groups. In group I (negative control), 10 rats received a vehicle injection after which a unilateral mandibular defect was created in each rat of all groups. Three groups were subjected to induction of osteoporosis by subcutaneous injection of 0.1 mg/kg/day dexamethasone for 60 days. In group II, rats were kept without treatment. In group III, rats were treated with daily intramuscular injection of 2.5 IU/kg of synthetic salmon calcitonin. In group IV, rats were handled as group III, and the created cavity was filled with emdogain. Rats were euthanized at 2nd and 4th week postsurgically. Hematoxylin and eosin, Masson’s trichrome, NF-κB (nuclear factor of activated B cells), and immunohistochemical stains were used, followed by statistical analysis. Results. Group I showed normal stages of bone defects healing. Group II revealed the formation of granulation tissue with dilated blood vessels, while groups III and IV showed enhanced bone healing and proper collagen fibers. The percentage area of newly formed collagen fibers was significantly higher in group IV at 2nd week (13.96 ± 0.020%) and 4th week (16.95 ± 0.024%) than in group II (8.75 ± 0.015% and 10.29 ± 0.015%, respectively) and group III (12.93 ± 0.015% and 14.61 ± 0.021%, respectively), but was lower than that in group I (15.75 ± 0.015% and 17.49 ± 0.015%, respectively). Conclusion. The local application of emdogain combined with systemically injected calcitonin improves bone healing in surgically induced bone defects in osteoporotic rats.

The Difference

The scientific experiment was carried out in two stages at State enterprise pilot farm “Hontarivka”, Vovchansk district, Kharkiv region. First stage. In a retrospective analysis of the rearing calf intensity from 3 to 6 months revealed that the highest live weight at 6-month age had animals of group III, .which is probably 47.0 kg or 34.6% and 23.0 kg or 14.4% (P < 0.001 in both comparison cases) outperformed peers I and II groups. A similar trend was observed in the analysis of live weight of heifers at 9 and 12-month age. Live weight at insemination in the higher growth group also had better rates of 4.0 and 3.7%, respectively, in animals of groups I and II (P < 0.001–0.05). It should be noted that the required live weight for insemination at heifers at growth rates of up to 500 g was reached in only 20.3 months, however, in the other two groups, the insemination age decreased by 1.5 and 1.7 months. Firstcalf heifers from group III also had the highest milk expectancy of 170.0 and 123.0 kg, or 3.1 and 2.3%, respectively, then animals in groups I and II. In the age period from 6 to 9 months it was found that at 9-month age heifers of group III had a higher live weight against animals of I and II groups respectively by 39.0 and 16.0 kg or 18.8 and 7.0% (P < 0.001 in both comparison cases). Intergroup differences by this indicator at 12-month age hiefers decreased to 35.0 and 8.0 kg, respectively, or 13.0 and 2.7% (P < 0.001 in both cases of comparison), which provided an advantage for the live weight of group III over I and II groups during the first fruitful insemination. Whereas the age of first fruitfull insemination, on the contrary, was lower at heifers of group III at 49 and 34 days than at groups I and II heifers. The highest milk productivity was also found at firstcalf heifers of group III at 634 kg or 12.3% (P < 0.001) and at 137 kg or 2.5% against animal I and II groups. The heifer live weight at the period from 9 to 12 months corresponded to the established differences at other age periods generally. And 12-month age calves of group III also significantly exceeded the analogues of group I by 38.0 kg or 14.0% (P < 0.001) and peers of group II – by 23.0 kg or 8.0% (P < 0.001). The live weight at fruitfull insemination of group III heifers was the largest and the difference compared with animals of group I was 21.0 kg or 5.3% (P < 0.01) and group II – 19.0 kg or 4.8% (P < 0.001). Group III animals also had the highest milk productivity, which is likely to be higher than group I peers by 751 kg or 14.5% (P < 0.001) and group II animals by 552 kg or 10.3% (P < 0.001). Second stage. It was found that during the experiment, live weight of free-stall keeping heifers were outnumbered by peers. In particular, the live weight of group I animals at the first month of the experiment was less by 8.0 kg or 2.9%, the second by 15.0 kg or 4.7% (P < 0.05) and the third by 19.0 kg or 5.4% against peers of group II. A similar pattern was observed in the estimation of intensive growth of these animals. However, at the end of the experiment, the heifers of the experimental group were 7.0 cm or 5.9% (P < 0.001) higher in the withers, 7.0 cm or 5.6% (P < 0.001) in the back, and the sacrum – 6.0 cm or 4.7% (P < 0.001). They showed deeper breasts by 3.0 cm or 4.9% (P < 0.01), larger breast widths – by 2.0 cm or 5.4% (P < 0.01), width in macaques – by 2.0 cm or 4.9% (P < 0.01), oblique torso length – 8.0 cm or 5.8% (P < 0.001), chest circumference 9.0 cm or 5.6% (P < 0.001) and girth – 1.0 cm or 6.1% (P < 0.01). It should be noted that from the second month of the research the animal number the free-stall keeping animal number, which ready for insemination, was more at 2.3 times or 5 goals than stall keeping heifers, and their live weight was more at 8 kg or 3.0%. With age, the differences between the groups gradually increased and by the third month reached 8 goals or 2.6 times and 19.0 kg or 5.7%.

As result of the presence of defects in the dentition, a range of morphological, aesthetic and functional changes arises, which considerably complicates the process of diagnosis and treatment of this pathology. Defects in the dentition, in combination with a variety of anomalies and deformations, often impede the implementation of rational prosthetics, and occasionally make it, impracticable at all one to this reason, one of the urgent problems in modern dentistry, which requires further, is the study of adverse factors that arise in the prosthetics of dental defects in adult patients with dentoalveolar anomalies and deformations of different etiologies. The aim is to investigate the prevalence of dental anomalies and deformities in adult patients’ prosthetic treatment. Materials and methods. 83 patients aged 20-60 and older were involved in prosthetic treatment. The diagnosis was based on classification have been of surveyed on Kennedy and D.A. Calveliss. Patients were divided into 4 age groups: Group I included 49 patients aged 20 to 30 years; Group II included 10 patients aged 31 to 40 years; Group III included 13 patients aged 41 to 50 years; IV group contained 11 patients aged 51 to 60 years and older. Results. In the 1st group, with coverage of 49 persons aged 20 to 30 years 12,5% of women suffered from defects of dentition which was under half the size of that of men (29,4%).All patients with dental defects needed prosthetic treatment. The prevailing majority of the surveyed-96,9% of females and 100% of males were diagnosed with dental anomalies. In group II, with 10 patients being examined in the 31-40 aged bracket, a significant increase in the number of persons with dental defects was observed: in women by 5.7 times up to 71,4% and in men-by 2.7 times up to 66,7% in comparing with those in Group I. Each of the examined patients with dental defects needed protection and orthodontic treatment. All patients in the third group (41-50 years) and the in IV group ( 51-60 years and older) of defects of dentitions were 50.0% women and 57.1% men of the third group and 71,4% of women and 75,0% of men of the IV group needed prosthetics of secondary dentition of teeth. Al l women of both subgroups have been diagnosed with dental anomalies, whereas in men. Orthodontic pathology was detected in 85,7% of individuals of group III and 75,0% of individuals group IV. Conclusions. Prosthetic treatment with restoration of the integrity of the dentition is one of the reasons for the significant growth of secondary deformations and the formation of dentoalveolar anomalies. According to our observations, patients 30 years of age or older who seek orthopedic help have defects in the dentition. Most often, these patients are diagnosed with included dentition defects in the lateral areas (from 35.3% to 63.6%), which are complicated by secondary deformations of the dentition (from 33.3% to 100%). The results of the studies confirm the need for further study of the state of the dentoalveolar system in patients with dentition defects, namely: the formation of secondary deformations, occlusion disorders, changes in the shape and size of the dentition, decrease in occlusion height, temporomandibular joint dysfunction, blockage or forced mandibular position etc.

Descriptive Scale

The incidence of varicose disease of the lower extremities throughout the world remains at a fairly high level. Given its socio-economic significance, low-impact surgical treatment methods continue to improve, as well as methods of anesthesia for them. In most cases, the mixtures used for infiltration anesthesia during endovenous surgery include lidocaine and adrenaline. The active substance of adrenaline, epinephrine hydrochloride, has a direct stimulating effect on α- and β-adrenergic receptors, and can cause serious disturbances in the cardiovascular system. It is not recommended for patients with CVD and endocrine system pathologies. Aim. minimize pain when performing tumescent anesthesia during endovenous radiofrequency obliteration of veins. Material and Methods. A comparative study was performed in which 192 patients with clinical forms of chronic C2-C6 venous disease took part. All patients using the envelope method were divided into three groups: patients of the first group (I) planned to perform RFO and miniphlebectomy using Klein mixture for tumescent anesthesia, the pH of which was 6.6, lidocaine concentration 0.04%. Patients of the second group (II) planned anesthesia using a solution, the pH of which was 7.3, the concentration of lidocaine was 0.02%. In patients of the third group (III), a solution with a pH of 7.4 was used, the concentration of lidocaine was 0.08%. The level of pain during the administration of the anesthetic was evaluated using two scales – the verbal descriptive scale of pain assessment (VASOB) and the visual analogue scale (VAS). Results. Patient groups were comparable in age, sex, clinical form of the disease. When assessing pain on a verbal descriptive scale, 50% of patients (27) in group II noted a complete absence of pain during tumescent anesthesia, in group III – 54.5% (48). Very severe pain (8 points) was noted by 4 patients from Group I, who were anesthetized by administering a Klein mixture, which constituted 8%; unbearable pain (10 points) also noted two patients from this group (4%). According to YOUR, the average pain in the first group was 3.02 ± 1.07, in the second – 1.13 ± 0.23, in the third – 0.93 ± 0.27 (p = 0.05). Pronounced pain (more than 5 cm according to YOUR) was noted only in the first group in 12 patients (24%). Conclusion. None of the test solutions completely removed pain during tumescent paravasal anesthesia. But the use of a solution with a pH of 7.3-7.4 is less painful when administered and significantly reduces pain during tumescent anesthesia, which was used in patients of groups II and III.

Green leaves of Tetrapterys multiglandulosa A. Juss were fed to pregnant goats from day 35 of pregnancy. Five goats received 10g/kgBW (group I), five received 20g/kgBW (group II) and five were used as control (group III), and received only hay, fresh grass and commercial ration. All animals were clinically examined daily and submitted to ultrasonography every three days. Fetal death and vulvar catarrhal discharge with subsequent abortion were observed at the end of the second month of pregnancy in group II and at the third month of pregnancy in group I. Animals from groups I and II were slaughtered after abortion and necropsied. Goats from the control group were necropsied at the same time. The main lesions in the aborted goats were focal placentitis with early involution (apoptosis) and placentary coagulation necrosis, acute focal endometritis and vulvo-vaginal petechiae. All aborted fetuses were underdeveloped when compared to control fetuses, probably due to fetal malnutrition, since no congenital malformations could be noted. The majority of aborted fetuses showed some degree of autolysis, as fetal death occurred five and three days before abortion, in groups I and II, respectively. The most remarkable fetal lesions were focal or diffuse hemorrhages in the skin, meninges and visceral serosae.

Malignant degeneration is the most serious complication of gastric ulcer. Its recognition is difficult both in the early stage and in advanced cases in which only the evidence of a previous ulcer-cavity, and the radiating folds of the mucous membrane indicate progressive development of carcinoma from an original ulcer. It is impossible to say how often gastric ulcer becomes malignant; one can only state the frequency of ulcer-carcinoma, found in gastric resections. One hundred and forty-one personal cases of ulcer-carcinoma are recorded, and are divided into three groups. Group I: 41 which were diagnosed clinically and at operation as cases of ulcer, but in which histological examination showed incipient cancer. Group II: 55 diagnosed clinically as cases of ulcer, but in which a diagnosis of ulcer-carcinoma was made during operation and afterwards histologically confirmed. Group III: 45 diagnosed both clinically and macroscopically (from the typical folding of the mucous membrane) as cases of ulcer-cancer, in which the cancer had entirely overgrown the ulcer. Therefore in the series of 532 resections for gastric ulcer the frequency of ulcer-carcinoma was 20.9%, or 15.2% if the third group is omitted. In a series of 718 resections for gastric cancer, the frequency of ulcer-carcinoma was 19.6% (or 14.2% if the third group is omitted). The mortality in simple two-third resection of the stomach is low (four deaths in 99 cases = 4%). When the pancreas, liver, colon, or œsophagus, is involved, the resection mortality is high (14 deaths in 42 cases = 33.3%), but even in these cases the operation is justifiable because permanent cures were achieved in a number of cases. The prognosis in cases of ulcer-cancer is very grave. In many cases, judging from the author's own experience, patients suffering from incipient ulcer-cancer—only histologically diagnosed as cancer—die from liver metastases, in spite of radical resection. It will thus be seen that the end-results of resection for ulcer-carcinoma are actually worse than those of resection for primary carcinoma. A. Ulcer-cancer: In Group I, 35 cases were operated on before 1933, and in 18 of these (51.4%) the patients have been free from symptoms for more than five years; in Group II, 27 cases were operated on before 1933, and in four of these (14.8%) the patients are still symptom-free. In Group III, out of 37 cases operated on, only two patients (5.4%) have been symptom-free for the same period. B. Primary cancer: Out of 260 cases of resection for primary cancer before 1933, 77 patients (29.6%) are permanently cured. If the ulcer-cancer is so far advanced that the diagnosis can be made clinically, or during operation, the prognosis is extremely bad (permanent cures having been only 9.3% in the series). In cases of gastric ulcer the best plan is to carry out resection before malignant degeneration begins. The result would then be that not merely 51% but at least 90% of the patients would be alive and well after five years.

Clays are natural ingredients used to prepare therapeutic cataplasms suitable for topical application. The knowledge about these formulations and their preparations to be applied on humans and animals has been orally transmitted since ancient times. Several empirical methods using clays have demonstrated fast and effective results in the reduction of the inflammatory response and the formation of edemas in horse limbs. The use of traditional and alternative medicine, such as pelotherapy, is now becoming more popular in veterinarian medical practice, alone or combined with other therapies in horse muscle and tendon rehabilitation. This study characterizes the use of commercial equine clays and an old therapeutic clay cataplasm formulation, using acetic acid, to treat tendon injuries in horses. This work might contribute to a major database characterization of clays used empirically on equine health, the potential of dermal absorption, the risks of exposure to some toxic elements, and safety assessment for these formulations. The present study was carried out to characterize the suitability of four commercial equine clays (Group II) and a protocoled healing mixture: “clay acetic acid cataplasm”, (Group III), to treat tendon injuries in horses. In this mixture, three conventional “green” clays (Group I) without any mineralogical specificity were used and blended with acetic acid. The mineralogical composition was determined through X-ray powder diffraction and X-ray fluorescence data. To determine the performance of the samples, cooling kinetics, oil absorption, expandability, and specific surface area were measured. According to the mineralogical composition, Group I was mainly composed of carbonates and silicates, while Group II was much richer in silicates with the main clay minerals kaolinite and illite. Group II exhibited the highest values for As, Pb, Cr, Ni, and Zn, considered potentially toxic. Both groups showed low cation exchange capacities and exchanged mainly Ca2+, with the exception of VET.1 and VET.7, which also highlight Na+, and VET.5 and VET.6, which have K+ as an exchangeable main cation. The addition of acetic acid (Group III) does not reveal any significant chemical changes. The results confirm that both clay groups are adequate for the therapeutic propose. They have good plastic properties (skin adherence), good oil absorptive capabilities (cleaning), and exchange an essential physiological element, calcium. Group II has prior industrial preparation, which is probably why it showed better results. Group I presented lower heat retention capacity and higher abrasiveness, which could be improved using cosmetic additives. The clinical benefit of the “clay acetic acid cataplasm” (Group III) could be the systemic anti-inflammatory effect established by the acetic acid.

Abstract Background:To explore the impact of seropositivity on systemic bone loss in rheumatoid arthritis (RA).Methods:This was an interim analysis of the RA registry. Clinical characteristics in the registry were documented, and bone mineral density (BMD) was measured; this was repeated 3 years later. Participants were grouped into seropositive (SPRA) and seronegative (SNRA) based on the presence or absence of rheumatoid factor (RF) and/or anti-cyclic citrullinated peptide antibodies (ACPA). After matching (1:2) for age and sex, SNRA and SPRA were regrouped into A and B. To elucidate the impact of number of antibodies on BMD changes, the matched group was sub-divided according to the number of antibodies present (0, group I; 1, group II; 2, group III). The changes in BMD were compared for each group at baseline and 3 years later. Results:A total of 477 participants who completed a 3-year observation period were included. After matching, 312 participants were enrolled (group A, 104; group B, 208). Three years later, group B had significant bone loss in the femoral neck (FN) (p <0.001), total hip (TH) (p = 0.001), and 1st–4th lumbar vertebrae (L1–4) (p = 0.006), while group A has bone loss only at FN (p = 0.002). Groups I, II, and III included 104, 52, and 156 participants, respectively. Significant bone loss was recorded at FN (p = 0.002) in group I, FN (p <0.001) in group II, and FN (p <0.001), TH (p = 0.002), and L1–4 (p = 0.016) in group III. In terms of percent change in BMD (△BMD%), more significantly negative changes were found at TH in group B (p = 0.027) and within groups I-III (p for trend = 0.021). Logistic regression showed that seropositivity is a significant predictor of △BMD≧–5% at TH (odds ratio 1.85, 95% confidence interval 1.03-3.33, p = 0.039).Conclusions:SPRA lost more bone than SNRA after 3 years. More attention should be paid to SPRA patients, especially those with double-positive antibodies, with vigorous evaluation of BMD and fracture risk.
