Fatigue Fracture of Titanium Alloy Knee Prostheses
Authors: Gilbert Jeremy L. , David Stulberg S.
Published: May 2019

Total knee prostheses were retrieved from patients after radiographs revealed fracture of the Ti-6A1-4 VELI metal backing of the polyethylene tibial component. The components were analyzed using scanning electron microscopy. Porous coated and uncoated tibial trays were found to have failed by fatigue. Implants with porous coatings showed significant loss of the bead coating and subsequent migration of the beads to the articulating surface between the polyethylene tibial component and the femoral component, resulting in significant third-body wear and degradation of the polyethylene. The sintered porous coating exhibited multiple regions where fatigue fracture of the neck region occurred, as well as indications that the sintering process did not fully incorporate the beads onto the substrate. Better process control during sintering and use of subsequent heat treatments to ensure a bimodal microstructure were recommended.
Fracture of a Cast Stainless Steel Femoral Prosthesis
Authors: D'Antonio Carmine
Published: May 2019

A cast stainless steel femoral head replacement prosthesis fractured midway down the stem within 13 months of implantation. Visual examination showed severe “orange peel” around the fracture on the concave side. This effect was not observed on the convex side, which suggested fatigue fracture. Metallographic examination of samples revealed an extremely large grain size and corroborated fatigue fracture. Chemical analysis indicated that the material conformed to the requirements for type 316L stainless steel. Substandard-size tensile bars machined from another prosthesis from the same manufacturer showing identical grain sizes were used for mechanical testing. Tensile tests indicated that the material did not meet the manufacturer's stated strength criteria in the portion of the stem that fractured. The failure was attributed to low strength, which resulted in fatigue. The extremely coarse grain size was considered a major factor in strength reduction.

Authors: Neff Michael
Published: May 2019

Music wire springs used in a printer return mechanism failed near the bend in the hook portion of the spring during qualification testing. Samples were examined in a scanning electron microscope equipped with an energy-dispersive x-ray microprobe. Fatigue fractures originated at rub marks on the inside edge of the spring. An investigation of loads encountered in service indicated that the springs had been loaded to a large fraction of the yield strength. Redesign of the spring mechanism was recommended.

Authors: Hahn Sarah Jane
Published: May 2019

The first-stage nozzles of a high-pressure turbine section of an industrial gas turbine exhibited leading and trailing-edge deterioration. The nozzles were made of X-40, a cobalt-base alloy, and were aluminide coated. Failure analysis determined that the deterioration was the result of hot corrosion caused by a combination of contaminants, cooling-hole blockage, and coating loss.
Cracking in an Aircraft Main Landing Gear Sliding Strut
Authors: Barter S.A. , Clerk G.
Published: May 2019

Examination of several fighter aircraft main landing gear legs revealed unusual cracking in the hard chromium plating that covered the sliding section of the inner strut. The cracking was associated with cracks in the 35 NCD 16 steel beneath the plating. A detailed investigation revealed that the cracking was caused by the combination of incorrect grinding procedure, the presence of hydrogen, and fatigue. The grinding damage generated tensile stresses in the steel, which caused intergranular cracking during the plating cycle. The intergranular cracks were initiation sites for fatigue crack growth during service. It was recommended that the damaged undercarriage struts be withdrawn from service pending further analysis and development of a repair technique.
Failure of a Transport Aircraft Relay Valve Guide
Authors: Das A.K.
Published: May 2019

A 52000 bearing steel valve guide component operating in the fuel supply system of a transport aircraft broke into two pieces after 26 h of flight. The valve guide fractured through a set of elongated holes that had been electrodischarge machined into the component. Analysis indicated that the part failed by low cycle fatigue. The fracture was brittle in nature and had originated at a severely eroded zone of craters in a hard, deep white layer that was the result of remelting during electrodischarge machining. It was recommended that the remaining parts be inspected using a stereoscopic microscope and/or a borescope.
Failure of a Copper Condenser Dashpot
Authors: Kaul Rakesh , Muralidharan N.G. , Raghu N. , Kasiviswanathan K.V. , Raj Baldev
Published: May 2019

A copper condenser dashpot in a refrigeration plant failed prematurely. The dashpot was a long tubular component with a cup brazed at each end. Stereomicroscopic examination of the fracture surface at low magnification revealed a typical ductile mode of failure. The failure was attributed to insufficient component thickness, which made the dashpot unable to withstand internal operating pressure, and to extensive annealing in the heat-affected zones of the brazed joints. It was recommended that the condenser dashpot design take into account the annealing effects of brazing. Hydrostatic testing at a pressure times greater than the maximum operating pressure prior to placing the component in service was also suggested.

Authors: Khatak H.S. , Gnanamoorthy J.B.
Published: May 2019

Leaks developed at random locations in aluminum brass condenser tubes within the first year of operation of a steam condenser in a nuclear power plant. One failed tube underwent scanning electron microscopy surface examination and optical microscope metallography. It was determined that the tube failed from crevice corrosion under seawater deposits that had formed on the inner surface. Mechanical cleaning of the condenser tubes every 6 months and installation of intake screens of smaller mesh size were recommended.
Failure of Welded Helium Tanks
Authors: Khatak H.S. , Seetharaman V. , Gnanamoorthy J.B.
Published: May 2019

Two tanks made of AISI type 304 stainless steel exhibited cracking in the heat-affected zone (HAZ) of the weld that joined the dished end and the shell. The dished ends had been produced by cold deformation. Hardness measurement and simulation tests showed that the deformation was equivalent to a 30% reduction in thickness. Residual stresses were measured at about 135 MPa (20 ksi). The HAZ was found to be sensitized. The tanks had been stored in a coastal atmosphere for about 4 years before installation. The failure was attributed to intergranular stress-corrosion cracking in a sensitized HAZ due to chloride from the environment. Use of low-carbon type AISI 304L was recommended. Minimization of fit-up stresses and covering with polyethylene sheets during storage were also suggested.

Failure analysis indicated that the blade fractured in three modes: crack initiation, fatigue crack propagation, and final rapid fracture in a ductile manner The fatigue crack originated near a rivet hole.
Thrust Bearing Failure Leading to the Destruction of a Propeller Rotor
Authors: Panontin Tina L.
Published: May 2019

An accidental overspeed condition during wind tunnel testing resulted in the destruction of a propeller rotor The occurrence was initially attributed to malfunction in the collective pitch control system. All fractured parts in the system were inspected. Highly suspect parts, including the pitch control thrust bearing set, head bolts, hub fork, and actuator rod end, were examined in more detail The thrust bearing set (52100 steel) was identified as the probable source of the uncommanded pitch angle change. A complete failure analysis of the bearing indicated that failure was precipitated by excessive heating, causing cage disintegration, plastic flow of the races and balls, and eventual separation of inner and outer races. It was recommended that the bearing set be resized to accommodate the large thrust as and that a thermocouple be added to monitor the condition of the bearing during testing.
Cracking of a Main Boiler Feed Pump Impeller
Authors: Hodas Leonard J.
Published: May 2019

An investigation was conducted to determine the cause of numerous cracks and other defects on the surface of a cast ASTM A743 grade CA-15 stainless steel main boiler feed pump impeller. The surface was examined using a stereomicroscope, and macrofractography was conducted on several cross sections removed from the impeller body. Areas that appeared to have the most severe surface damage were sectioned, fractured open, and examined using SEM. The chemistry of the impeller and an apparent repair weld were also analyzed. The examination indicated that the cracks were shrinkage voids from the original casting process. Surface repair welds had been used to fill in or cover over larger shrinkage cavities. It was recommended that more stringent visual and nondestructive examination criteria be established for the castings.

Authors: Bravanec Edward V.
Published: May 2019

Cracking was discovered in an in-service, second-stage turbine impeller during a downtime inspection. The fabricated 4300 series low-alloy steel impeller was used in a compressor in an industrial petrochemical plant. It was also reported that a process upset had allowed a 10% NaOH solution to be ingested by the unit. Routine magnetic particle inspection revealed numerous cracks in the hub area and vane tips of the second-stage impeller Additionally, the outside surface of the backing plate showed a cyclic pattern of cracks. An overview of a conventional, systematic metallurgical approach to failure analysis to confirm that the cracking was caused by a caustic stress-corrosion cracking mechanism is presented.
Failure of Brass Hot Water Reheat Valves
Authors: D'Antonio Carmine
Published: May 2019

Two hot water reheat coil valves from a heating/ventilating/air-conditioning system failed in service. The values, a 353 copper alloy 19 mm (3/4 in.) valve and a 360 copper alloy 13 mm (1/2 in.) valve, had been failing at an increasing rate. The failures were confined to the stems and seats. Visual examination revealed severe localized metal loss in the form of deep grooves with smooth and wavy surfaces. Metallographic analysis of the grooved areas revealed uniform metal loss. No evidence of intergranular or selective attack indicating erosion-corrosion was observed, Recommendations included use of a higher-copper brass, cupronickel, or Monel for the valve seats and stems and operation of the valves in either the fully opened or closed position.
Cracking at the Threads of Stud Bolts Used for Lifting Plastic Mold Dies
Authors: Mackay W.B.F.
Published: May 2019

Two 38 mm (1.5 in.) diam threaded stud bolts that were part of a steel mold die assembly from a plastics molding operation were examined to determine their serviceability. Chemical analysis showed the material to be a plain carbon steel that approximated 1045. Visual examination revealed evidence of severe hammer blows to the clevis and boss areas and a gap between the die and the underside of the boss. Magnetic particle inspection showed cracks at the thread roots that, when examined metallographically, were found to contain MnS stringers. The cracking of the threads was attributed to a poor stud bolt design, which allowed a high stress concentration to occur at the base of the threads upon application of a lateral load. It was recommended that bolts of a new design that incorporated a stress-relieving groove be used. Threading of the bolt to eliminate the gap between the lower face of the boss and the die and an improved method of inserting or removing the bolt to avoid hammering (use of a wrench on a square or hexagonal boss) were also recommended.

The microstructure was tempered martensite, with hardness ranging from 41 to 45 HRC. Failure was in the shear ductile mode. The crack initiated in the area of slag inclusions. Inspection of other bolts from the same shipment was recommended.
Hydrogen Embrittlement Delayed Failure of a 4340 Steel Draw-In Bolt
Authors: Levy Eli
Published: May 2019

The draw-in bolt and collet from a vertical-spindle milling machine broke during routine cutting of blind recesses after a relatively long service life. The collet ejected at a high rotational speed due to loss of its vertical support and shattered one of its arms upon impact with the work table. SEM fractography and metallographic examinations conducted on the bolt revealed hairline indications along grain facets on the fracture surface and stepwise cracking in the material, both indicating failure by hydrogen embrittlement. Similar draw-in bolts were discarded and replaced with bolts manufactured using controlled processes.
Interpretacyjne problemy prawa geologicznego i górniczego - tzw. "połowy bursztynu"
Authors: Lipiński Aleksander
Published: May 2019

Bursztyn jest kopaliną, która jest objęta prawem własności gruntowej. Wyjątek dotyczy złóż znajdujących się poza granicami nieruchomości gruntowych, w tym w obszarach morskich. Stanowią one przedmiot własności górniczej, która przysługuje Skarbowi Państwa.

„Połów bursztynu” polega na zbieraniu bryłek bursztynu wypłukanego ze złóż podmorskich i znajdującego się pod wodą na niewielkiej głębokości obok linii brzegu. Przedmiotem prawa geologicznego o górniczego jest m.in. poszukiwanie (rozpoznawanie) oraz wydobywanie kopalin ze złóż. Wiele wskazuje na to, że opisane wyżej nagromadzenia bryłek bursztynu nie mogą być uważane za złoża w rozumieniu prawa geologicznego i górniczego. W konsekwencji ich „połów” nie będzie wymagał spełnienia przesłanek określonych wspomnianym prawem. Niejasny stan prawny powoduje natomiast, że ustalenie szczegółowych wymagań dotyczących omawianej działalności jest trudne.
Wykładnia rozszerzająca prawa ochrony środowiska jako szczególnej gałęzi prawa
Authors: Przybojewska Ilona
Published: May 2019

Przedmiotem niniejszego artykułu jest analiza roli wykładni rozszerzającej w ramach prawa ochrony środowiska. Jakkolwiek w zależności od przyjętej konwencji terminologicznej różnie ocenia się samodzielność prawa ochrony środowiska jako odrębnej od innych gałęzi prawa, nie ulega jednak wątpliwości, że prawo ochrony środowiska wykazuje szereg cech charakterystycznych, które odróżniają je od innych dziedzin. Jest to w szczególności obecność własnych zasad (jak zasada „zanieczyszczający płaci” czy zasada prewencji i zasada przezorności) czy wykorzystanie rynkowych instrumentach ochrony środowiska. Jest to zarazem obszar, który kształtuje się zarówno pod wpływem unijnego, jak i krajowego porządku prawnego. Powoduje to, że w ramach prawa ochrony środowiska następuje ścieranie się różnych tendencji dotyczących wykładni prawa, to jest z jednej strony prymatu wykładni literalnej, tradycyjnie przyjmowanego w odniesieniu do prawa polskiego, a z drugiej strony, nacisku na wykładnię celowościową, widocznego w orzecznictwie Trybunału Sprawiedliwości Unii Europejskiej. Ta ostatnia tendencja ulega wzmocnieniu poprzez oddziaływanie zasad i wartości leżących u podstaw prawa ochrony środowiska, co prowadzi do interesujących rezultatów interpretacyjnych.

Published: May 2019

The Borna Disease Virus (BDV) is a non-segmented RNA-containing virus belonging to the Bornaviridae family. The pathogen causes progressive meningoencephalitis in animals of various types. Despite numerous studies, some stages of reproduction of Bornavirus remain poorly understood, in particular, receptor-mediated penetration, retrograde transport into the nucleus, assembly and release of the virion, etc. The present report presents the results of demonstrating studies that were aimed at following the immunoenzyme method, the distribution of the main protein BDV ― phosphoprotein P (p24) in the brain cells of naturally susceptible animals, compare nnye data with the results of a number of authors, made mainly in experimental models. Microscopic examination of histological sections of the brain tissue of horses and sheep treated with specific serum against p24 BDV in a light or luminescent microscope observed a specific color in the form of: small granules; diffuse fluorescence of the cytoplasm; larger granules, apparently due to aggregation of endosomes, for axon transportation; formations in the form of beads, demonstrating the transport of viral material along the axon. In vitro results were obtained indicating that it is possible to transport RNPs via a short path through cytoplasmic bridges. The presented results will allow a better understanding of the neuropathogenesis of Born's disease and improve the diagnosis of the disease.

Published: May 2019

The article analyzes the prerequisites for creating community self-governance, the features of its functioning and efficiency. To do this, the authors use a variety of sources of information, including a number of surveys conducted in the city of Kirov (Russia). Evaluation of regression models shows that the conditions for the emergence of community self-governance include grassroots social capital and property rights, but at the same time citizens feel responsibility for the city and seek to gain the support of the authorities in solving local problems. At the same time, community self-governance emerges more often when people do not believe in the collective ability of society to achieve accountability and effective work of municipal authorities.

A stock control system is basically a database; it must keep the up-to-date records of all the stock. Adequate stock must be maintained to supply the customers with their needs and minimum delay. In manual inventory system, the information is difficult to share from one person to another and unexpected difficult is human error. To alleviate these difficulties and to ascertain the exact stock level of a company, this paper presents a design of stock control system on a petrol station using stock levels of inventory system such as reorder level, economic order quantity, and maximum level. To demonstrate the presented system, we apply it to a number of sale data in Lucky 7 petrol station in Mandalay. The stock control system is implemented by C# programming language and SQL server database.

Exposición a contaminantes provenientes de termoeléctricas a carbón y salud infantil: ¿Cuál es la evidencia internacional y nacional?
Authors: Cortes A. Sandra , Yohannessen V. Karla , Tellerías C. Lidya , Ahumada P. Ericka
Published: May 2019

Las centrales termoeléctricas (CTE) a carbón representan un riesgo para la salud de las comunidades expuestas. Se realizó una revisión de la literatura científica nacional e internacional enfocada en los efectos en salud de niños y la exposición a emisiones al aire provenientes de CTE a carbón. Se incluyeron 21 artículos para su revisión en texto completo, donde se midieron efectos en salud infantil relacionados a presencia de biomarcadores de exposición y efecto, daños perinatales, neuroconductuales y respiratorios principalmente. La exposición a emisiones de CTE a carbón en el embarazo se asoció a niños con bajo peso y muy bajo peso al nacer, menor talla, menor diámetro de Circunferencia del Cráneo (CC) y prematuridad; el diámetro de CC aumentó en recién nacidos después del cierre de CTE. Se encontraron menor coeficiente de desarrollo (CD) y coeficiente intelectual (CI) en niños expuestos a emisiones de CTE a carbón comparados con no expuestos; CD aumentó cuando la central fue cerrada. Por otro lado, vivir en zonas con fuentes de emisión de mercurio (asociadas a CTE y plantas de cemento que funcionan con carbón) se asoció con mayor riesgo de autismo. En salud respiratoria, los artículos fueron consistentes en reportar menor función pulmonar en niños residentes en zonas expuestas a fuentes de combustión de carbón comparados con grupos de niños no expuestos. Es muy necesario abrir el debate en Chile sobre los riesgos controlables a los que se enfrenta la población infantil a consecuencia de plantas generadoras de energía instaladas en Chile.

Published: May 2019

Introducción: La acalasia es el trastorno motor primario más frecuente del esófago. Su incidencia reportada es baja, aún más en pacientes pediátricos. La miotomía de Heller laparoscópica corresponde al estándar actual de tratamiento. Durante los últimos años la miotomía endoscópica por vía oral (POEM) se ha posicionado como una alternativa terapéutica segura y tan efectiva como el Heller para la acalasia esofágica. Objetivo: Describir la técnica de POEM y reportar el primer caso pediátrico en nuestro país. Caso clínico: Paciente de 11 años, previamente sano, que se presentó con disfagia ilógica progresiva y baja de peso. El estudio concluyó una acalasia tipo II. Fue sometido a POEM y cursó un postoperatorio sin incidentes. A un año de la intervención se ha documentado resolución de la sintomatología, seguimiento endoscópico y manométrico sin complicaciones. Conclusiones: El caso descrito corresponde al primer POEM en un paciente pediátrico en nuestro país. La acalasia esofágica es infrecuente en pediatría y el POEM ha demostrado éxito clínico y seguridad comparables a la miotomía de Heller laparoscópica en el corto y mediano plazo. El seguimiento a largo plazo permitirá determinar su rol definitivo en el tratamiento de pacientes pediátricos con acalasia esofágica.

Many years of experience in fighting and preventing of helminthiasis in waterfowl shows that the successful elimination of parasitic diseases is possible under the conditions of a complex of organizational and economic, veterinary and sanitary and special anti-parasitic measures, which must necessarily include deworming of poultry. The purpose of the work was to study the effectiveness of modern antihelminthic drugs for the spontaneous capillariasis geese. Experimental testing of antihelminthic preparations of domestic production was performed: piperazine 45% (DR – piperazine adipinat), 22% phenzole (DR – fenbendazole) and brovadazole plus (DR – piperazine adipinat, phenbendazole). The efficacy of the drugs was determined by the results of helminthic autopsy and coproscopicof the geese of the experimental and control groups. The main indicators of the action of drugs were extensiveness and intensive. It was established that according to the results of helminthocoproscopic investigations, the most effective drugs for capillariasis geese were phenzole 22% and brovadazole plus, their effectiveness at day 15 of the experiment was 100.0%. Efficiency (EE and IE) of piperazine 45% was slightly lower and at day 5 of treatment, according to the results of the coproscopy, was 40.0% and 65.0% respectively, for 10 days – 70.0% and 76.0%, for 15 days – 70% , 0 and 82.0%. At the same time, according to the results of helminthic autopsy geese in the process of their treatment, the effectiveness of the preparations of phenzole 22% and piperazine 45% were lower. EI of experimental geese for 15 days with the use of phenzole 22% was 40.0%, and II decreased from 21.20 ± 1.16 to 2.00 ± 1.00 ex./head. In the application of piperazine, 45% of the experimental poultry EI for 15 days reached 60.0%, II decreased from 22.40 ± 1.12 to 3.67 ± 0.58 ex./head. Extens- and intensefficiency of piperazine 45% was 40.0 and 86.0%, phenzole 22% – 60.0 and 92.0%, respectively. It was determined that the most effective preparation for geese capillariasis is brovadazole plus (EE, IE – 100.0%), which is confirmed by the results of coproscopic studies and helminthic autopsy. Based on the data obtained, confirmed by experimental studies, we recommend the use of the drug brovadazol plus in the control and prevention of capillariasis geese.

The results of the veterinary and sanitary examination of food products are based on data from Zhytomyr Regional State Laboratory of the State Service for Safety of Food and Consumer Protection and State Laboratories of Veterinary and Sanitary Expertise of Economic Markets in Zhytomyr and Zhytomyr Oblast for 2018. The main cause of detoxification of offal was invasive disease. Total sales: 80.26325 tons of products and 10397 positive results were obtained, out of which 92 carcasses, 4074 cases of invasive and non-communicable diseases – 10.262 tons, 6231 cases of other food products with a total weight of 70.00125. The analysis of the reporting documentation of the ZHDLDPPS and the state laboratories of all economic markets in Zhytomyr and Zhytomyr region showed that the main causes of milk and dairy products were: mechanical and bacterial contamination, falsification, subclinical mastics, inconsistency of organoleptic parameters with regulatory requirements, fat content and acidity, violation of terms of implementation. Screening test systems (Charm test Chloramphenicol, 4 sensors (antibiotics of Beta-lactam groups, Tetracyclines, Streptomycins, Chloramphenicol) 247 samples of raw milk were checked, of which 2.4% were positive. Security guarantor  dairy products in Ukraine remains a system for monitoring sanitary-dangerous pathogens and residual amounts of toxic substances. The pollution of forest fungi and game in the victims of the Chernobyl accident in the Zhytomyr region remains at a rather high level and they are the main source of danger to consumers. The most contaminated samples of fresh mushrooms, whose specific activity exceeded the regulatory requirements of DR-2006 for 137Cs content in 2018, were from Ovruch (5 samples 509.1 – 3375 Bq/kg), Native (1 sample – 1956 Bq/kg) and Zhitnaya Market of Zhytomyr (3 samples 2328–2345 bq/kg at a rate of 500 Bq/kg). Accordingly, samples of dry mushrooms at a norm of 2500 Bq/kg did not meet the normative requirements of Ovruch 1 (6329 Bq/kg), of the Nurses 2 samples (4330 Bq/kg and 4987 Bq/kg) and Olevsk 1 sample (2814Bk/kg. DLVSE the study of 28 samples of dry fungi showed that the specific activity of 50% of samples from the Ovruch region was 2520–5000 Bq/kg, 5.8% of samples from the Emilchinsky district – 2544–2923 Bq/kg, 7.2% of the samples from the Native -397– 29022 Bq/kg and 4.3% of samples from the Olevsk rayon – 2739–2892 Bq/kg. Of the LRDLDPPS examined, 3 samples of game – 1 sample from Ovruch exceeded the permissible levels by 2.3 times (464 Bq/kg), with Lugin in 3.3 times (634 Bq/kg), from the Native – 7.6 times (1531 Bq/kg) .And according to the DLVSE, the level of contamination of the game with 6 samples in the Germans – 4 samples (2000-12124 Bq/kg) In Samara, 1 sample in Korosten amounted to 1,500 Bq kg, of which 48 samples of milk tested by the DLVSE in the Germans all showed an excess of 137Cs (101-172 Bq/kg ), fish-2 samples – 203 and 590 Bq/kg.

Skin diseases in dogs and cats occupy one of the leading places among the diseases in these species of animals. The purpose of this work was to monitor the most common contagious skin diseases in dogs and cats (otodicosis, demodicosis, dermatomycosis) during 2018 in Odessa. To solve the goal several tasks were set: to find out the species and breed structure of dogs and cats otodicosis diseases; to find out the breed structure of dogs demodicosis diseases; to find out the species and breed structure of dogs and cats dermatomycosis diseases; to determine the seasonality of otodicosis, demodicosis and dermatomycosis of dogs and cats in Odessa city during 2018. The material was provided by the data concerning sick animals registered in logs on the basis of two veterinary clinics (Gabi and Aibolit) in Odessa. These logs data were entered in the tables and analyzed statistically. For the experimental period, 134 animals were infected with contagious skin diseases, among them 51 animals were infected with otodicosis, 34 animals – with demodicosis, and 49 animals-with dermatodicosis (trichophytosis and microsporia).  More cats than dogs suffered from otodicosis and demodicosis. The largest number of animals infected with otodicosis is represented by cats of  Metis breed (54.2%), cats of Scottish Fold breed amounted 8.3%, cats of Persian, Maine Coon and British Shorthairs breeds – by 6.3%. Dogs of Métis breed suffered from demodicosis largely, it accounted (29.4%), dogs of Pug breed accounted 14.7%, dogs of French Bulldog breed – 11.8%. Non pedigree cats – 86.2% and non pedigree dogs – 35% suffered with dermatomycosis. Otodicosis was registered every month, except January. The increase of disease was noted in June, August, October and December. Demodicosis was registered every month, except January. The increase of disease was noted in March, September, October and December. Dermatomycosis was registered every month. The increase of disease was noted in March-April and August-December. In order to control the epizootic situation regarding contagious skin diseases of carnivorous animals in Odessa city further systematic monitoring must be carried out.
The Incidence of Anal Sphincter Ruptures and Risk Factors
Authors: Santoso Budi I , Khusen Denny
Published: May 2019

Objective: To analyze the incidence of anal sphincter ruptures and

to evaluate risk factors of obstetric anal sphincter ruptures in Dr.

Cipto Mangunkusumo Hospital.

Method: We reviewed 2009 vaginal deliveries based on the analysis

of obstetric data base and patient records of our department during

2012. Cases and control subjects were chosen randomly and patient’s

records were reviewed for the following variable: maternal

age, parity, gestational age, labor induction, duration of 2nd stage labor,

use of forceps, use of vacuum, use of episiotomy, birth weight,

and presentation of the baby.

Result: There were 91 (4.53%) anal sphincter ruptures during period

of study (91 of 2009 patients). An univariate analysis of these

91 case and 91 randomly selected control subjects show that primiparity

(p = .000), gestational age (p = .016), duration of second-stage

labor (p = .000), forceps delivery (p = .000), vacuum delivery (p =

.001), episiotomy (p = .000), and birth weight (p = .000) increased

the risk for anal sphincter ruptures. In multivariate re-gression models,

only 5 of the 10 predictor variables were significantly related

to the likelihood of having a severe perineal trauma greater than second

degree. Primiparity (p = .023; OR 2.74, 95% [CI], 1.15-6.51),

forceps delivery (p = .000; OR 18.18, 95% [CI] 3.84-86.07), vacuum

delivery (p = .005; OR 6.83, 95% [CI] 1.77-26.42), episiotomy (p =

.015; OR 2.86, 95% [CI] 1.23-6.65), and birth weight (p = .000; OR

0.99, 95% [CI] 0.997-0.999).

Conclusion: Damage of the anal sphincter resulting in a third- or

fourth- degree perineal tear is a relatively rare but severe complication

of vaginal delivery. We found that factors as sociated with anal

sphincter ruptures were primiparity, forceps, vacuum, episiotomy

and birth weight.
