Liječenje iznenadne bradikardije i arterijske hipotenzije tijekom ekscizije feokromocitoma u psa – prikaz slučaja

An 11-year-old female spayed Shih Tzu was presented with a history of weight loss, lethargy and a heart murmur. After extensive diagnostics, an adrenal mass was discovered, suspected to be a pheochromocytoma, and surgical excision was planned. During anesthesia, no signs of catecholamine discharge were seen. However, sudden bradycardia and hypotension occurred, necessitating anticholinergic therapy. Such therapy is usually contraindicated in patients with pheochromocytoma due to the risk of significant tachycardia, cardiac arrhythmias, and arterial hypertension. No adverse effects were noted, and the dog recovered uneventfully from the procedure.Sterilizirana ženka pasmine ši-cu, starosti 11 godina, zaprimljena je zbog gubitka težine, letargije i srčanog šuma. Nakon opsežne dijagnostike, otkrivena je tvorba na nadbubregu te je postavljena sumnja na feokromocitom i planirana je njegova kirurška ekscizija. Tijekom anestezije nisu uočeni znakovi otpuštanja katekolamina. Naprotiv, nastupile su iznenadna bradikardija i hipotenzija, koje su zahtijevale terapiju antikolinergicima. Takva je terapija obično kontraindicirana u bolesnika s feokromocitomom zbog rizika razvoja tahikardije, srčanih aritmija i arterijske hipertenzije. Nisu primijećeni nikakvi štetni učinci terapije antikolinergikom, niti postoperativne komplikacije

EFFECT OF SULFACETAMIDE ON THE COMPOSITION OF CORROSION PRODUCTS FORMED ONTO CARBON STEEL SURFACE IN HYDROCHLORIC ACID

IUPAC name N- [(4-aminophenyl) sulfonyl] acetamide (APSA) on the corrosion of carbon steel in 1.0 M HCl solution has been investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and XPS analysis. The electrochemical measurements indicated that the presence of APSA in 1.0 M HCl solution decreases the corrosion current (i corr ) and increases the polarization rezistance (R p ). XPS surface analysis showed at this stage, in the absence of APSA, that the main product of corrosion is a non-stoichiometric Fe 3+ oxide/oxidehydroxide, consisting of a mixture of Fe 2 O 3 and FeO(OH), where FeO(OH) is the main phase. Moreover, in presence of inhibitor the surface layer consists of FeO(OH) rather than pure oxide, adsorbed molecules of sulfacetamide and inorganic compounds such as: sulfides, carbonates, sulphates, nitrates, which were obtained by electrochemical degradation of APSA. UV-Vis spectrophotometry and HPLC technique were performed to determine the medium composition before and after corrosion. The results showed a decrease of the inhibitor concentration in 1.0 M HCl solution after carbon steel corrosion, indicating an adsorption process between organic compound molecules from aqueous phase and the electrode surface and/or the electrochemical degradation of APSA

New System for the Acceleration of the Airflow in Wind Turbines

Background: This patent is based on the wind industry technology called Diffuser Augmented Wind Turbines (DAWTs). This technology consists of a horizontal axis wind turbine, which is housed inside a duct with diverging section in the direction of the free air stream. In this paper, a review of preceding patents related to this technology is carried out. Objective: This paper presents an innovative patent to improve the performance of horizontal axis wind turbines. In particular, this system is aimed at improving the performance of those turbines that otherwise might not be installed due to the low wind resource existing at certain locations. Methods: The most innovative elements of this patent are: (1) the semi-spherical grooves, which are mechanized on the surface of the two diffusers in order to guarantee a more energetic boundary layer; (2) the coaxial diffuser, which is located downwind following the first diffuser in order to increase the suction effect on the air mass close to the inlet; (3) the coaxial rings located around the first diffuser outlet, which are used to deflect the external airflow toward the turbine wake; and (4), the selforientating system to orientate the system by the prevailing wind direction. Results: An application of the patent for increasing the power generated by a horizontal axis wind turbine with three blades is presented. The patent is designed and its performance is evaluated by using a Computational Fluid Dynamics code. The numerical results show that this system rises the airflow going through the rotor of the turbine. Conclusion: The patented device is an original contribution aimed at enabling a more profitable installation of wind turbines in places where the wind resource is insufficient because of the wind shear caused both by the proximity of the earth and the obstacles on the earth surface.This work was supported by the OASIS Research Project that was cofinanced by CDTI (Spanish Science and Innovation Ministry) and developed with the Spanish companies: Iridium, OHL Concesiones, Abertis, Sice, Indra, Dragados, OHL, Geocisa, GMV, Asfaltos Augusta, Hidrofersa, Eipsa, PyG, CPS, AEC and Torre de Comares Arquitectos S.L and 16 research centres.

Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

A Rare Case of Acute Abdomen: Garengeot Hernia

Rezumat Un caz rar de abdomen acut: hernie Garengeot Asocierea apendicitei acute cu hernia femuralã strangulatã sau încarceratã, reprezintã o patologie rar întâlnitã, dar bine documentatã în literatura de specialitate medicalã, aaea numita hernie a lui Garengeot. Dezvoltarea unei apendicite acute în sacul de hernie femuralã, devine o urgenåã chirurgicalã de abdomen acut. Diagnosticul este întotdeauna confundat cu cel de hernie încarceratã sau strangulatã, diagnosticul de certitudine fiind stabilit intraoperator, ocazie cu care la deschiderea sacului herniar se constatã prezenåa apendicelui cecal, aflat în diferite stadii morfologice ale inflamaåiei, care pot merge pânã la gangrena aei perforaåia acestuia. În aceastã lucrare, am raportat cazul unei femei de 76 de ani, care se prezintã pentru prezenåa unei formaåiuni tumorale femurale, încarcerate, dureroase, care a fost iniåial consideratã ca hernie femuralã încarceratã, diagnosticul final fiind stabilit intraoperator. Tratamentul acestor "hernii" este în general simplu, atunci când nu existã complicaåii ale apendicitei acute, precum prezenåa de puroi în sacul de hernie, aei constã în apendicectomie aei herniorafie. Absenåa unei simptomatologii specifice apendicitei acute, face ca de cele mai multe ori intervenåia chirurgicalã sã fie temporizatã ceea ce duce la apariåia frecventã a complicaåiilor aei la creaeterea morbiditãåii. Cuvinte cheie: hernie femuralã, încarcerare, apendicitã Abstract The association of acute appendicitis with femoral hernia, strangulated or incarcerated, represents a rare but well documented pathology in the specialized medical literature, also known as Garengeot hernia. The development of an acute appendicitis in the femoral hernia sac becomes a surgical emergency of acute abdomen. The diagnosis is always mistaken for the one of incarcerated or strangled hernia, the correct diagnosis being established intraoperatively, occasion which exposes the cecal appendix by opening the herniary bag, found in different morphological stages of inflammation that can go as far as gangrene or even perforation. In this paper, we have reported the case of a 76 year-old female that presented with femoral tumours, incarcerated, painful and initially considered as an incarcerated femoral hernia, the final diagnosis being made intraoperatively. The treatment for these "hernias" is generally simple, when there are no complications of acute appendicitis as the presence of pus in the hernia sac, and consists in appendectomy and herniorrhaphy. The absence of symptoms for an acute appendicitis often delays the surgery which leads to frequent complications and increased rate of morbidity

Corrosion Inhibition of Carbon Steel in Hydrochloric Acid Solution Using a Sulfa Drug

The corrosion inhibition of carbon steel in 1.0 mol L–1 HCl in the presence of an antibacterial sulfa drug Sulfathiazole, IUPAC name 4-amino-N-(1,3-thiazol-2-yl) benzene sulfonamide (TBSA) was investigated using mass loss and electrochemical measurements such as: potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Surface chemistry was analyzed by X-ray photoelectron spectroscopy (XPS). For the study of the surface morphology scanning electron spectroscopy (SEM) was used. The results showed that TBSA acts as a corrosion inhibitor in 1.0 mol L–1 HCl solution by suppressing simultaneously the cathodic and anodic processes via adsorption on the carbon steel surface and that the inhibition efficiency increases with increasing concentration. XPS analysis revealed that the corrosion product consists of an oxyhydroxide/oxide mixture and that the iron oxyhydroxide proportion is higher than the iron oxide proportion

Preliminary investigation of thermal behaviour of PCM based latent heat thermal energy storage

Solid-liquid phase change is used to accumulate and release cold in latent heat thermal energy storage (LHTES) in order to reduce energy consumption of air cooling system in buildings. The storing capacity of the LHTES depends greatly on the exterior air temperatures during the summer nights. One approach in intensifying heat transfer is by increasing the air’s velocity. A LHTES was designed to be integrated in the air cooling system of a building located in Bucharest, during the month of July. This study presents a numerical investigation concerning the impact of air inlet temperatures and air velocity on the formation of solid PCM, on the cold storing capacity and energy consumption of the LHTES. The peak amount of accumulated cold is reached at different air velocities depending on air inlet temperature. For inlet temperatures of 14°C and 15°C, an increase of air velocity above 50% will not lead to higher amounts of cold being stored. For Bucharest during the hottest night of the year, a 100 % increase in air velocity will result in 5.02% more cold being stored, at an increase in electrical energy consumption of 25.30%, when compared to the reference values
