When a joint becomes infected, the increased pressure due to the influx of immune mediators presses on the joint capsule nerves and causes pain. Pain is also caused by the change in the cellularity of the joint fluid as neutrophils enter the joint fluid in an attempt to battle the infection. The inflammation and inflammatory mediators are responsible for pitting edema Joints are at risk for infection through puncture wounds. Any cut over the surface of a joint can allow the entry of bacteria into that joint. If this is the case, the infection will be localized, as it is in this case, and it will be possible to diagnose by collecting fluid via a joint tap and prerfoming baterial culture. We would expect the radiographs to show an increase in soft tissue swelling and increased capsular fluid. This explains the fact that the problem exisist only in the right fetlock. Another rule out to is the possibility of a systemic infection. The age of this filly leads us to consider joint ill. In neonates it is possible for bacteria to gain entry to the systemic blood by way of the umbillicus. A systemic infection may be introduced by other routes as well. In either case the bacteria then collect in the joints of the neonate and cause pain and lameness. As systemic infection such as this will eventually cause the foal to show other signs of illness, such as increased fever and may stop nursing. Upon physical exam of the foal, we would expect a hot and swollen umbillicus in the case of naval ill and possibly other signs of systemic disease. A CBC, blood chemistry and blood and joint fluid culture would all be methods necessary to diagnose this condition. This hypothesis explains the physical exam findings of soft tissue edema with pitting edema caused by the inflammation in the joint. Also the fact that there is no instability or crepitance on palpation. ╡ ─├ф х ╡ ¤¤¤¤¤¤¤─├Э╗G ┘ у ф х ╡ ■■■■■■ ░╨/ ░р=!░"░#Ра$Ра%░ [4@ё 4NormalCJOJPJQJmH <A@Є б<Default Paragraph Font╡       ╡╡ ╡ ╡ *5я∙·азЦа&Щг╖г┘I┌╖   Math Emporium?Macintosh HD:Desktop Folder:Student's Folder:3hypothesis3_a.txt Math EmporiumLMacintosh HD:Desktop Folder:Student's Folder:AutoRecovery save of 3hypothesi Math EmporiumLMacintosh HD:Desktop Folder:Student's Folder:AutoRecovery save of 3hypothesi Math Emporium?Macintosh HD:Desktop Folder:Student's Folder:3hypothesis3_b.txt Math Emporium?Macintosh HD:Desktop Folder:Student's Folder:3hypothesis3_c.txt @А┘┘НН┘G5╡`@GРTimes New Roman5РАSymbol3Р Arial3РTimes"qИ╨hc┌RFc┌RF!е└┤┤А0╨   Hypothesis 3: Math Emporium Math Emporium■  рЕЯЄ∙OhлС+'│┘0lИРи┤╠╪ш   ( 4 @LT\d'Hypothesis 3:oypoMath EmporiumoathNormalpMath Emporiumo2thMicrosoft Word 8.0d@МЖG@┬Щv╩а└@┬Щv╩а└■  ╒═╒Ь.УЧ+,∙о0 hpИРШа и░╕└ ╚ т'Virginia Tech3м Hypothesis 3: Title ■   ■   ■    !"#$%&■   ¤   )■   ■   ■                                                                                                                                                                                                                                                                                                                                                   Root Entry         └Fж$паа└+А1Table            WordDocument        SummaryInformation(    DocumentSummaryInformation8            CompObj    XObjectPool            ж$паа└ж$паа└            ■                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           ■      └FMicrosoft Word Document■   NB6WWord.Document.8
