RESUMO
Because of the efficacy of proton pump inhibitors (PPIs), their the use is increasing dramatically. The risk of adverse effects of short-term PPI therapy is low, but there are important safety concerns for potential adverse effects of prolonged PPI therapy. Findings from studies assessing the association between PPI use and bone mineral density (BMD) and/or fracture risk are contradictory. The aim of this study was to prospectively assess potential association of PPI treatment with the 12-month change in BMD of the lumbar spine, femur neck, and total hip. The study was performed in 200 PPI users and 50 PPI nonusers. Lumbar spine (L1-L4), femur neck, and total hip BMD were measured by dual-energy X-ray absorptiometry at the baseline and at 12 months. A total of 209 subjects completed the entire 12 months of the study and were included in the final analysis. A Wilcoxon signed-rank test showed that at 12 months PPI use was associated with statistically significant reductions in femur neck and total hip T scores (Z = -2.764, p = 0.005 and Z = -3.281, p = 0.001, respectively). A multiple linear regression analysis showed that only esomeprazole added significantly to the prediction of total lumbar spine and femur neck T scores (p = 0.048 and p = 0.037, respectively). Compared with the baseline, 12 months of PPI treatment resulted in lower femur neck and total hip BMD T scores. Among the four PPIs studied, esomeprazole was independently associated with significant reduction of BMD, whereas omeprazole had no effects on BMD. Considering the widespread use of PPIs, BMD screening should be considered in the case of prolonged PPI use.

OBJECTIVE: Role of the atelectasis (hypoxia) in the respiratory system of the live and exited newborn (250 up to 3000 g. of body weight), which has died due to different causes was studied in this work. METHODS: Response of tracheal rings to dopamine, serotonine and ethanol in the different molar concentrations (dopamine: 0.05 mg/ml, 0.5 mg/ml, 5 mg/ml; serotonine (5-HT): 10(-4), 10(-3), 10(-2), 10(-1) mol/dm3; ethanol: 0.2 ml, 0.5 ml, 1.0 ml; 96%) was followed up. Study of the smooth tracheal musculature tone (STM) was elaborated in 16 tracheal preparations taken following the newborn death due to different causes. RESULTS: Based on functional researches of tracheal isolated preparations, it was ascertained as follows: atelectasis (cases born with lung hypoxia) has changed the response of STM to dopamine, serotonine and ethanol in a significant manner (p < 0.01) in comparison to cases of controlling group, which has died due to lung inflammatory processes (e.g. pneumonia, bronchopneumonia, cerebral hemorrhage), which have also caused significant response (p < 0.05). CONCLUSION: Results suggest that exited cases from lung atelectasis and cases of controlling group reacts to above mentioned substances by causing significant constrictor action of tracheobronchial system.

BACKGROUND AND OBJECTIVE: There is paucity of evidence in southeastern Europe and Kosovo regarding dairy products consumption and association with bone mineral density (BMD). Therefore, the objective of present study was to assess calcium intake and dairy products consumption and to investigate relationship with total hip BMD in a Kosovo women sample. METHODS: This cross-sectional study included a sample of 185 women divided into respective groups according to total hip BMD. All the study participants completed a food frequency questionnaire and underwent dual-energy X-ray absorptiometry (DEXA) to estimate BMD. Nonparametric tests were performed to compare characteristics of the groups. RESULTS: The average dietary calcium intake was 818.41 mg/day. Only 16.75% of the subjects met calcium recommended dietary reference intakes (DRIs). There were no significant differences between low BMD group and normal BMD group regarding average dietary calcium intake, but it was significantly higher in BMDT3 subgroup than in BMDT2 and BMDT1 subgroups. CONCLUSIONS: The results of this study demonstrate significant relationship of daily dietary calcium intake with upper BMD tertile. Further initiatives are warranted from this study to highlight the importance of nutrition education.

OBJECTIVE: In this work, role of hypoxia in respiratory system on live and exited newborns weight 250-3000g.) which have died due to different reasons is studied. METHODS: Response of tracheal rings in acetylcholine and histamine in different molar concentrations (10(-4), 10(-3), 10(-2), 10(-1) mol/dm3) was monitored. Study of the tracheal smooth musculature (TSM) tonus was performed in 12 tracheal preparations obtained from the newborns exited due to different reasons. RESULTS: Based on the functional analysis of the isolated tracheal preparations, we have concluded that the cases born with lung atelectasis have caused significant response ofTSM to Acetylcholine and Histamine (p > 0.01). In cases of control group, which has exited due to different reasons from lung inflammatory processes (e.g.: pneumonia, bronchopneumonia, cerebral hemorrhage), Acetylcholine and Histamine have also caused significant constriction of tracheal smooth musculature. CONCLUSION: Results suggest that exited cases with lung atelectasis (hypoxemia) and cases of lung inflammatory processes have significant constrictor action to Acetylcholine and Histamine in tracheobronchial system.

INTRODUCTION: This work, partial pressure of the respiratory gases in the capillary blood (pH, PaO2, PaCO2) was studied, following the protective action of the beta2-drenergic stimulator-Hexoprenaline and alpha2-adrenergic blocker-Tolazoline in the bronchoconstriction caused by a beta-blocker-Propranolol. MATERIAL AND METHODS: in patients with increased bronchial reactibility. pH, oxygen partial pressure (PaO2), dioxide carbon partial pressure (PaCO2) in the arterial blood, with the assistance of the analyzer IL, following some minutes of sample taking were defined in all patients. As a standard to verify the accuracy of the measurement, ampoule solutions of pH, PaO2 and PaCO2 were utilized (Acidobasel, Berlin). RESULTS AND DISCUSSION: Following the inhalation of the beta-blocker-Propranolol (20 mg/ml-aerosol), there was an evident decrease (p < 0.05) of pO2 and a non-significant increase (p > 0.1) of pCO2. Beta2-adrenergcic stimulator-Hexoprenaline (2 inh x 0.2 mg), shows an protective effect in the decrease of pO2 (p < 0.05) following the bronchoconstriction being provoked by Propranolol. Alpha2-adrenergic blocker-Tolazoline (20 mg/ml-aerosol), has not shown a protective action in the bronchoconstriction caused with propranolol, therefore significant decrease (p < 0.05) of pO2 and a non-significant increase (p > 0.1) of pCO2 appeared. This shows that stimulation of beta2-adrenergic receptor has protective action in changes of the respiratory gases. Meantime, blocker of the alpha2-adrenergic receptor (Tolazoline) has not shown a protective action in changes of the respiratory gases.

OBJECTIVE: Antibiotics misuse and a high level of antibiotics resistance is observed worldwide, but particularly in developing countries. Kosovo in the last decade is facing challenges regarding antimicrobial resistance. The purpose of the present study was to investigate patterns of antibiotics prescriptions of dentists in Kosovo's major dental clinics. MATERIALS AND METHODS: For Kosovo's prescribing pattern, data collection was obtained from 10 Regional Dental Clinics and a Tertiary Health Center regarding patients who were prescribed antibiotics in the years 2015 to 2019. Data analysis was performed by using descriptive statistics and was processed by using MS Excel. RESULTS: Most prescribed antibiotic during the observed period from 2015 to 2019 in Kosovo was amoxicillin, although a drastic increase of amoxicillin with clavulanic acid-as a broad-spectrum antibiotic-is observed. The trend of antibiotics use in tertiary health institutions is in an overall decrease in Kosovo with an exception in the year 2017. Despite this overall decrease, inconsistency in prescribing is observed when the pattern is analyzed for each region separately. The highest number of patients in health care dental clinics received antibiotics for maxilla-related health conditions and the lowest number of them for oncologic ones. CONCLUSION: The patterns of antibiotics prescriptions by dental practitioners in Kosovo during the years 2015 to 2019 are fluctuating. Compared with the global health care standards, the irrational use of antibiotics in dental health care clinics in Kosovo still exist and this issue should be further addressed by respective actors.
RESUMO
CONTEXT: Kosovo is a region in the Western Balkans that is rich in minerals and coal, so pollution is a serious public health problem there. Workers in the heavy and precious metal smeltery in Zveqan, Kosovo, were studied with regard to the roles that vapor from the smelting of metals (Pb, Zn, Au, Ag, P, and Cu) and particulate matter play in causing bronchial hyperreactivity. OBJECTIVES: The purpose of the article was to measure the parameters of lung function as determined by body plethysmography, diagnosis of respiratory diseases, and assessment of respiratory function using a histamine bronchoprovocation test. SETTINGS AND DESIGN: The present study was conducted in two groups of participants: A control group, which included 25 healthy persons, and a smeltery worker group, which included 45 mine workers (15 smokers and 30 nonsmokers) holding permanent jobs in the mineral foundry of Zvecan, Kosovo. SUBJECTS AND METHODS: Pulmonary function parameters (specific airway resistance [Raw] and intrathoracic gas volume) were measured and used to calculate the specific resistance (SRaw)and specific conductance (SGaw) of the airways, and a histamine bronchoprovocation test was conducted. STATISTICAL ANALYSIS USED: The data were entered and analyzed using the Microsoft Excel and INSTAT 3 software. RESULTS: Airway specific resistance (SRaw) was significantly higher in the smeltery worker group (P < 0.01) as compared to the control group (P > 0.1). CONCLUSION: These results suggest that occupational exposure to vapors during the metal refining process poses a risk to the workers' health and can cause bronchial hyperreactivity, bronchial asthma, or chronic obstructive pulmonary disease.
RESUMO
Volume density of respiratory organs was studied in vitro in newborn babies at different age of gestation (abort, immature, premature and mature) using stereometric method. The total of 23 cases was subject to this study. The respiratory organs (trachea, lungs) were taken from autopsies of newborn babies exited from different causes. For this purpose the tissues were fixed in formalin (10%) solution, cut serially in 7micro and 10micro slabs. Volume density of the respiratory system was assessed stereometricaly using Universal testing system Weibel M 42. We observed that volume density of epithelia, musculature and glands were proportionally present in the tracheal tissue. Cellular interstitial tissue is consistently increasing and corresponds to the developmental stages of the newborn babies. The density of tracheal ganglions is greater in premature ages of immature and premature newborns (p<0,05). Decreased number of ganglion cells is observed in mature ages (p<0,05). This is caused by intensive ramification of ganglions from serosa to deeper layers of trachea right to epithelium. Medium diameter of tracheal ganglions is greater in mature newborn babies and corresponds to developmental ages of babies.

The role of meconium in the respiratory system was studied in newborns, who died from various causes (250 up to 3000 g of weight). We monitored tracheal rings response to dopamine, serotonin and ethanol in different concentrations (dopamine: 0,05 mg/ml, 0,5 mg/ml, 5 mg/ml; serotonin (5-HT): 10-4, 10-3, 10-2, 10-1 mol/dm3; ethanol: 0,02 ml, 0,5 ml, 1,0 ml; 96%). Tracheal smooth musculature tonus (TSM) was examined in 48 tracheal preparations taken after the newborn exitus due to different reasons. Based on functional researche of isolated preparations of tracheas, it may be concluded that: aspiration of meconium has not changed the response of TSM to dopamine, serotonin and ethanol (p>0,1) in comparison with the control group, which have died due to different lung inflammatory processes (e.g. pneumonia, bronchopneumonia, atelectasis, cerebral hemorrhage). The results suggest that meconium does not potentiate the constricting action of dopamine, serotonin and ethanol in tracheobronchial system. Meconium causes mild relaxation of the TSM through a mechanism that is not intermediated by the products of cyclooxygenases (prostaglandins, prostacyclins) from the tracheal epithelium or proteins. Also, as it seems, the direct activity of many tested acids in the smooth musculature has no significant impact on increase of the airways tonus in MAS syndrome.

Actions of acetylcholine (ACh), histamines, serotonins (5-HT) and prostaglandins (PGF2-alfa) in concentrations of 10(-4), 10(-3), 10(-2) and 10(-1) mol/dm(3) were analyzed in vitro conditions in isolated specimens of tracheas of 24 pigs, 7 guinea pigs, and dead persons for different reasons (8), in the presence and without presence of propranolol. Whilst, research regarding actions of aerosolized histamines (10 mg, 1%, 2 min), in the presence and without the presence of aerosolized propranolol (20 mg, 2%, 2 min) was done in vivo in 6 healthy persons. Study results show that propranolol does not emphasize contraction of the airways smooth musculature as induced by ACh, histamine, 5-HT and PGF2-alfa in vitro conditions (p>0,1). Also, in vivo we found a non-significance of tracheal smooth musculature constriction (p>0,1).

Morphological aspect of tracheal preparations and pulmonary tissue was studied in vitro. The material was obtained from autopsy of newborns that died from different causes. Examinations were made in different gestational periods (immature 23-29 weeks; premature 30-37 weeks; mature >38 weeks). Material for examination was obtained up to 6 hours after death. Pulmonary and tracheal tissue was incubated for fixation in buffered formalin (10%). Special histochemical and histoenzymatic methods were used for coloring of pulmonary and tracheal tissue and the activity of ATP-ase and dopaoxidase was monitored. Cut out models were made in series of 7 micro, 10 micro and 20 micro. In peripheral axons of tracheobronchial pathways, degenerative alterations of adrenergic nerve endings in lung inflammatory processes were documented. These morphologic neuronal changes were described: Walerians degeneration, neuro-axonal degeneration and segment demyelinisation. These changes are well seen with argentafine coloring (Sevier-Munger modification for nerve endings) and with dopaoxidase reaction. In mature newborns that died from respiratory distress syndrome, we found different forms of metabolic and toxic degenerative damage in peripheral axons, such as: segment demyelinisation, neurotubular fragmentation, Schwann cell proliferation, fragmentation and bulging out of axonal neurotubules and neurofilaments. In tracheo-bronchial tissue, chromafine granules are homogeneously distributed on Lamina propria layer and through glandular structures. This gives as a contradiction, according to some authors, that adrenergic nerve fibers for muscle tissue are absent and that adrenaline and noradrenaline diffuse in muscle tissue from interstice.

The development of neuron cells in vagal nerve nuclei in medulla oblongata was studied in vitro in live newborns and stillborns from different cases. Morphological changes were studied in respiratory nuclei of dorsal motor centre (DMNV) and nucleus tractus solitarius (NTS) in medulla oblongata. The material from medulla oblongata was fixated in 10 micro buffered formalin solution. Fixated material was cut in series of 10mu thickness, with starting point from obex in +/- 4 mm thickness. Special histochemical and histoenzymatic methods for central nervous system were used: cresyl echt violet coloring, tolyidin blue, Sevier-Munger modification and Grimelius coloring. In immature newborns (abortions and immature) in dorsal motor nucleus of the vagus (DMNV) population stages S1, S2, S3 are dominant. In neuron population in vagal sensory nuclei (NTS) stages S1, S2 are dominant. In more advanced stages of development of newborns (premature), in DMNV stages S3 and S4 are seen and in NTS stages S2 and S3 are dominant. In mature phase of newborns (maturity) in vagal nucleus DMNV stages S5 and S6 are dominant, while in sensory nucleus NTS stages S4 and S5 are dominant. These data suggest that neuron population in dorsal motor nucleus of the vagus (DMNV) are more advanced in neuronal maturity in comparison with sensory neuron population of vagal sensory nucleus NTS. This occurrence shows that phylogenetic development of motor complex is more advanced than the sensory one, which is expected to take new information's from the extra uterine life after birth (extra uterine vagal phenotype).

AIM: Blocking effect of leukotriene biosynthesis-zileuton and blocking the effect of phosphodiesterase enzyme-diprophylline in the treatment of patients with bronchial asthma and bronchial increased reactivity, and tiotropium bromide as an antagonist of the muscarinic receptor studied in this work. METHODS: Parameters of the lung function are determined with Body plethysmography. The resistance of the airways (Raw) was registered and measured was intrathoracic gas volume (ITGV), and specific resistance (SRaw) was also calculated. For the research, administered was zileuton (tabl. 600 mg) and diprophylline (tabl. 150 mg). RESULTS: Two days after in-house administration of leukotriene biosynthesis blocker-zileuton (4 x 600 mg orally), on the day 3 initial values of patients measured and afterwards administered 1 tablet of zileuton, and again measured was Raw and ITGV, after 60, 90 and 120 min. and calculated was SRaw; (p < 0.01). Diprophylline administered 7 days at home in a dose of (2 x 150 mg orally), on the day 8 to same patients administered 1 tablet of diprophylline, and performed measurements of Raw, ITGV, after 60, 90 and 120 min, and calculated the SRaw (p < 0.05). Treatment of the control group with tiotropium bromide - antagonist of the muscarinic receptor (2 inh. x 0.18 mcg), is effective in removal of the increased bronchomotor tonus, by also causing the significant decrease of the resistance (Raw), respectively of the specific resistance (SRaw), (p < 0.05). CONCLUSION: Effect of zileuton in blocking of leukotriene biosynthesis is not immediate after oral administration, but the effect seen on the third day of cys-LTs' inhibition, and leukotriene B4 (LTB4) and A4 (LTA4) in patients with bronchial reactivity and bronchial asthma, which is expressed with a high significance, (p < 0.01). Blockage of phosphodiesterase enzyme-diprophylline decreases the bronchial reactivity, which is expressed with a moderate significance, (p < 0.05).
RESUMO
AIM: Here we studied the role of meconium in the respiratory system on live and exited newborns (weight 250-3000 g). Throughout this study is followed the response of tracheal rings in acetylcholine and histamine in different molar concentrations (10-1, 10-2, 10-3, 10-4 mol/dm3). METHODS: To study the smooth tracheal musculature we used 23 tracheal preparations obtained from the newborns exited from meconium aspiration. RESULTS: Based on the functional analysis of the tracheal specimen we have concluded that the meconium aspiration did not change the smooth musculature response on acetylcholine and histamine when compared to control group, exited from lung inflammatory processes (e.g., pneumonia, bronchopneumonia, atelectasis, cerebral hemorrhage), where tracheal smooth musculature response is significant (P for other causes is not significant (P > 0.01). CONCLUSION: The conclusions suggest that meconium did not potentiate the constrictor action of acetylcholine and histamine in the tracheobronchial system and did not cause modulation of bronchomotor tonus in case of his aspiration. Meconium causes mild relaxation of smooth tracheal musculature with a mechanism which is not mediated by cyclooxygenase products, from tracheal epithelium or proteins. Also, direct activity in the smooth musculature of several tested acids seems to have no significant impact in increasing the tonus of respiratory airway of smooth tracheal musculature.
RESUMO
BACKGROUND/AIMS: Proton pump inhibitors (PPIs) are a widely used class of drugs because of a generally acceptable safety profile. Among recently raised safety issues of the long-term use of PPIs is the increased risk of developing hypomagnesemia. As there have been very few prospective studies measuring serum magnesium levels before and after PPI therapy, we aimed to prospectively assess the potential association between PPI therapy for 12 months and the risk of hypomagnesemia as well as the incidence of new-onset hypomagnesemia during the study. In addition, the association of PPI therapy with the risk of hypocalcemia was assessed. MATERIALS AND METHODS: The study included 250 patients with normal serum magnesium and total calcium levels, who underwent a long-term PPI treatment. Serum magnesium, total calcium, and parathormone (PTH) levels were measured at baseline and after 12 months. RESULTS: Of the 250 study participants, 209 completed 12 months of treatment and were included in the statistical analysis. The Wilcoxon signed rank test showed no statistically significant differences in serum magnesium levels between measurements at two different time points. However, there were statistically significant differences in serum total calcium and PTH levels in PPI users. CONCLUSION: Stable serum magnesium levels were demonstrated after 12 months and no association between PPI use and risk of hypomagnesemia was shown in the general population. Significant reductions of serum total calcium levels were demonstrated among PPI users; nevertheless, further research is required before recommending any serum calcium and PTH level monitoring in patients initiated on long-term PPI therapy.

Research was done on pharmacological-physiological development of the bronchial receptor system on the smooth muscles of trachea in the newborn children, alive-born and stillborn children. Monitored was the response on: acetylcholine, dopamine, histamine and serotonin in different molar concentrations 10(-4), 10(-3), 10(-2), 10 mol/dm(-3), micromol/dm(-3)). Research was done on tonus of tracheal smooth muscles of 23 tracheal preparations taken by autopsy after death from different factors. Based on pharmacological-physiological research on the preparations of human isolated trachea it was find out that: acetylcholine stimulation effect is significant (p>0,01) in 38-41 weeks of pregnancy comparing with that in 30-37 weeks of pregnancy (p>0,01), while dopamine stimulation effect is significant (p>0,05) in 30-37 pregnancy weeks comparing with the effect of acetylcholine and dopamine on the still-born infants of the same pregnancy period (p<0,01). Histaminic receptors were developed during intrauterine life after 38 weeks of pregnancy (p>0,025). Serotonin has caused contraction of the bronchial smooth muscles after 30 pregnancy weeks, but response was not significant (p<0,01). This suggests that cholinergic and adrenergic system of the airways in alive newborn infants develops in parallel intrauterine, contrary to other systems which develop in certain extrauterine life phases.

OBJECTIVE: This paper reveals the studies of carbamazepine monitoring in the manifestation of side effects during clinical use. It is important to realize that these ranges are derived statistically, with most patients who have high levels suffering side effects and some with poor control having low levels. Broadly, the newer agents have advantages of lower risk of side effects and less drug interaction. At the presence they are more expensive than the, than "older" agents. Current recommendations and practice are to use newer agents as second line drugs, although in some countries there are gaining favour as potential first line agents. METHODS: In the study 91 patients with epilepsy were involved from which 53 or 58.2% were female and 38 or 41.8% were male with no great significant difference between two genders (X(2)=2.47, P=0.116). However, according to the study results female patients had slightly greater prevalence of epilepsy than man. Average age of epileptic patients was 23.2 years (SD ± 16.4 years), in the range 1-66 years. Patient distribution was present within all age-groups, but 59.4% of all patients were up to 20 years old. The highest prevalence of epilepsy was in the group age 6-15 years old: 33.0%. There were also children 1 - 5 years old with 7 or 7.7% of the patients, and the patients older than 60 years with 4 or 4.4% of the patients. Patient distribution according to the age and gender results with no female patient over 60 year old and more female patients in the age group 1-5 years. However statistically this did not produce a highly significant difference (T-test= 0.72, P=0.437) between average age according to the gender. The average age of the female gender was 22.1 year (SD ± 14.2 years), with the range 2-55 years, while the average age of the male patients was 24.6 year (SD ±19.2 years), with the range 1-66 years. CONCLUSION: Unwanted side effects of antiepileptic drugs analyzed in the study are frequent, but not so severe as to be life threatening. Treatment of epilepsy with these three drugs (carbamazepine, ac.valproic and phenobarbitone) would be the first choice of treatment, with the best safety and efficacy. Application of this therapy is rarely compromised because of the appearance of unwanted side effects. Replacement or termination of therapy may be applied if actual therapy is not adequate for the management of epileptic attacks.
RESUMO
OBJECTIVE: Effect of glucocorticoids-budesonide and antileukotriene-montelukast in patients with bronchial asthma and bronchial increased reactivity was studied in this work. METHODS: Parameters of the lung function are determined with Body plethysmography. Raw and ITGV were registered and specific resistance (SRaw) was also calculated. RESULTS: Results of this research, in patients with bronchial asthma, indicate that glucocorticoids - budesonide (Pulmicort; 2 × 2 mg inh) has significant action (p< 0.01) on reduction of the specific resistance (SRaw) of airways, applied to the same patients 3 days after administration of montelukast, at home (2 × 10 mg). Three days after administration of the montelukast, antileukotriene medicine, at home, on the fourth day same patients administered a capsule of montelukast, 10 mg dose per os, and significantly (p < 0.05) reduced the increased bronchomotor tonus; and the effect of the control with salbutamol (beta2-adrenergic agonist) is effective in removal of the increased bronchomotor tonus, causing significant decrease of the resistance (Raw), respectively of the specific resistance (SRaw), (p < 0, 01). CONCLUSION: This suggests that the bronchodilator effect of glucocorticoids is more powerful than of the leukotriene, because glucocorticoids terminate the early stage of chemical mediator release (prostaglandins PgD2, SRS, and leukotriene LTC4, LTD4, LTE4 and Cytokinins also etc.) as powerful bronchoconstriction substances, whilst antileukotriene substances does not have this feature.
RESUMO
OBJECTIVE: In this work, effect of tamsulosin as antagonist of alpha1A and alpha1B adrenergic receptor and effect of agonists of beta2 adrenergic receptor-salbutamol in patients with increased bronchial reactibility was studied. METHODS: Parameters of the lung function are determined with Body plethysmography six (6) hours after administration of tamsulosin. Raw and ITGV were registered and specific resistance (SRaw) was calculated as well. Tamsulosin was administered in per os manner as a preparation in the shape of the capsules with a brand name of "Prolosin", produced by Niche Generics Limited, Hitchin, Herts. RESULTS: After six (6) hours of administration of tamsulosin, results gained indicate that blockage of alpha1A and alpha1B-adrenergic receptor (0.8 mg per os) has not changed significantly (p > 0.1) the bronchomotor tonus of tracheobronchial tree in comparison to the check-up that has inhaled salbutamol agonist of adrenergic beta2 receptor (2 inh. x 0.2 mg), (p < 0.05). Blood pressure suffered no significant decrease following administration of the 0.8 mg dose of tamsulosin. CONCLUSION: This suggests that even after six hours of administration of tamsulosin, and determining of lung function parameters, the activity of alpha1A and alpha1B-adrenergic receptor in the smooth bronchial musculature has not changed in patients with increased bronchial reactibility.
RESUMO
OBJECTIVE: According to the ''vascular'' theory, arterial overflow in the superior hemorrhoidal arteries would lead to dilatation of the hemorrhoidal venous plexus. Hemorrhoid laser procedure (LHP) is a new laser procedure for outpatient treatment of hemorrhoids in which hemorrhoidal arterial flow feeding the hemorrhoidal plexus is stopped by laser coagulation. AIM: Our aim was to compare the hemorrhoid laser procedure with open surgical procedure for outpatient treatment of symptomatic hemorrhoids. MATERIAL AND METHOD: A comparison trial between hemorrhoid laser procedure or open surgical hemorrhoidectomy was made. This study was conducted at Aloka hospital in Kosovo. Patients with symptomatic grade III or grade IV hemorrhoids with minimal or complete mucosal prolapse were eligible for the study: 20 patients treated with the laser hemorrhoidoplasty, and 20 patients-with open surgery hemorrhoidectomy. Operative time and postoperative pain with visual analog scale, were evaluated. RESULTS: A total number of 40 patients (23 men and 17 women, mean age, 46 years) entered the trial. Significant differences between laser hemorrhoidoplasty and open surgical procedure were observed in operative time and early postoperative pain. There was a statistically significant difference between the two groups regarding the early postoperative period: 1 week, 2 weeks, 3 weeks and 1 month after respective procedure (p<0.01). The procedure time for LHP was 15.94 min vs. 26.76 min for open surgery (p<0.01). CONCLUSION: The laser hemorrhoidoplasty procedure was more effective than open surgical hemorrhoidectomy. Postoperative pain and duration time are only two indicators for this difference between there procedures.
