Pott’s Puffy Tumor (Obulwadde bw’amagumba g’omu maaso n’okuzimba mu bitundu by’omubiri ebiyitibwa Subperiosteal Abscess Oluvannyuma lw’okuzimba ekyenyi mu maaso): Okuzimba mu kyenyi mu ngeri ey’obuwunga n’okusunsulamu ebizimba mu mutwe¶

Wadde ng’erinnya lyayo ery’ebyafaayo libuzaabuza, Ekizimba kya Pott ekifuukuuse si kookolo oba neoplasm: mbeera ya mangu ey’okulongoosa ey’okusiigibwa ey’amaanyi, etta obulamu bw’omuntu nga mu mbeera eno etajjanjabiddwa oba etajjanjabiddwa ekitundu acute bacterial frontal skultis (oba minor blunt forehead trauma) ekulukuta mu maaso okuyita mu emmeeza y’omu maaso ey’eggumba ly’omu maaso, okusitula oluwuzi olw’ebweru olukaluba olw’ekiwanga (periosteum / pericranium) okukola ensawo y’amasira ebuguma, ennyogovu, erimu ensaano, erimu ebitosi (subperiosteal abscess) butereevu wakati oba ku ludda lw’ekyenyi. Yasooka okunnyonnyolwa omusawo Omuzungu Sir Percivall Pott mu 1760, embeera eno ye bendera emmyufu enkulu ey’okulongoosa obusimu kubanga bbugwe w’emabega (posterior table) ya sinus y’omu maaso tewera kitundu kya buwanvu bwa bbugwe w’omu maaso era egabana omukutu gwa emisuwa egy’ekika kya diploic egitalina vvaalu (veins of Breschet) ezikulukuta butereevu emabega mu dural venous sinuses ne frontal lobes z’obwongo. N’olwekyo, wakati wa 60 and 85 percent wa baana n’abakadde (ne 30 to 40 percent wa bantu abakulu) abeeyanjula n’ekizimba kya Pott ekifuukuuse ku ludda olw’ebweru w’ekyenyi kyabwe DDA bakuuma ekizibu ky’omutwe ekiyitibwa Intracranial Complication (epidural abscess, subdural empyema, frontal lobe brain abscess, or superior sagittal sinus thrombosis) munda mu kiwanga kyabwe. Singa omwana, omutiini, oba omuntu omukulu alina obulwadde bwa sinus mu kiseera kino oba gye buvuddeko oba okuzimba omutwe afuna okuzimba mu kitundu, okugonvu, okuwunya, oba okukyukakyuka ku kyenyi waggulu w’ebisige, okulumwa ennyo omutwe mu maaso, omusujja, okuzimba ebikowe ebya waggulu, okusiiyibwa, oba enkyukakyuka mu buntu/obukoowu obutonotono, kuba essimu y’omuntu ow’omu kitundu kyo ennamba z’amangu (911 mu Amerika ne Canada, . 112 okwetoloola omukago gwa Bulaaya, . 999 mu Bungereza, oba 000 mu Australia) oba okugenda amangu ddala mu kitongole ky’eddwaaliro eky’amangu. Nga weetegekera entambula, weetegereze ebiragiro byaffe ebikwatagana nabyo ku... obulwadde bwa cellulitis obuyitibwa orbital cellulitis ne cavernous sinus thrombosis, . obulwadde bw’okuzimba omutwe n’okusunsulamu obuwuka obuyitibwa meningococcal septicemia, era acute coalescent mastoiditis n’obulabe bw’okuzimba ku bwongo.

1. Lwaki Ekizimba kya Pott Ekifuukuuse Kiba Kiwuka kya Polymicrobial Microaerophilic & Anaerobic Infection¶

Olw’okuba omusuwa gw’omu maaso oguzibiddwa gufuuka ekituli ekitaliimu oxygen omutono (hypoxic and acidic) cavity, obuwuka obuleeta ekizimba kya Pott ekifuukuuse n’ebizimba byakyo eby’omu mutwe byawukana nnyo ku yinfekisoni z’amatu oba olususu ennyangu: - Ekibinja ky'abamenyi b'amateeka #1 (50% to 70%): Ekirungo kya Streptococcus anginosus ( .Streptococcus milleri) Ekibinja (S. anginosus, S. constellatus, ne S. intermedius) n’ebiwuka ebirala ebiyitibwa viridans streptococci ebisikiriza omukka omutono. Ekibinja kya Streptococcus intermedius / milleri kimanyiddwa nnyo mu ddagala ly’endwadde ezisiigibwa olw’okukola enziyiza ey’amaanyi (hyaluronidase and deoxyribonuclease) esaanuusa amagumba n’ekola ebizimba eby’obwongo n’eby’omu bitundu by’omubiri ebisaanyaawo. - Strict Oral & Sinus Anaerobes (30% to 50%): Ebika bya Fusobacterium (F. nucleatum, F. necrophorum), Prevotella, Porphyromonas, Bacteroides, ne Peptostreptococcus (ebibeerawo mu mbeera ezisinga obungi nga zigaziwa mu mutwe). - Obulwadde bwa Staphylococcus aureus (15% to 25%, omuli MRSA): Naddala kitera mu mbeera z’oluvannyuma lw’okulumwa, abatiini, n’obulwadde bwa sinusitis obutawona. - Streptococcus pneumoniae, Obulwadde bwa ssennyiga, ne Streptococcus pyogenes (Group A Strep).

2. Enkola y’eddagala eritta obuwuka eriweebwa mu misuwa mu ngeri ey’amangu (Meningeal / Brain Abscess Dosing) .¶

Amangu ddala nga obuwangwa bw’omusaayi bukubiddwa (era nga tetunnalinda MRI okuggwa), abasawo batandika enkola y’eddagala eritta obuwuka eriyingira mu misuwa ery’eddagala ssatu: 1. Eddagala lya Vancomycin eriweebwa mu misuwa (15 to 20 mg/kg IV every 6 to 8 hours) (okubikka ekiziyiza methicillin S. aureus [MRSA] n’obuziyiza penicillin S. ekifuba), PLUS 2. Eddagala lya Ceftriaxone eriweebwa mu misuwa (2 grams IV every 12 hours mu bantu abakulu; 100 mg/kg/day divided q12h mu baana: full meningeal double-dose) OBA Intravenous Cefotaxime / Cefepime (okutuuka ku miwendo gya CSF n’amagumba egy’amaanyi okusinziira ku kibinja kya Streptococcus anginosus/milleri n’emiggo egya Gram-negative), PLUS 3. Eddagala lya Metronidazole eriweebwa mu misuwa (500 mg IV every 6 to 8 hours mu bantu abakulu; 30 to 40 mg/kg/day mu baana) (kubanga metronidazole etuuka ku kumpi-100% okuyingira mu bizimba by’obwongo, subdural pus, ne necrotic frontal bone okumalawo anaerobes enkakali nga Fusobacterium ne Prevotella). - (Enkola endala: Meropenem mu misuwa + Vancomycin ayisibwa mu misuwa). - Ebbanga Ery’Okujjanjaba: Olw’okuba ekizimba kya Pott ekifuukuuse mu ntegeeza acute osteomyelitis of the frontal skull bone (emirundi mingi nga kigattibwa n’ekizimba eky’omu misuwa/subdural), abalwadde beetaaga wiiki 6 ku 8 ezijjuvu ez’obujjanjabi obugendereddwamu mu misuwa (oba high-bioavailability prolonged IV-to-oral step-down) antibiotic therapy via layini ya PICC oluvannyuma lw’okulongoosebwa okufulumya amazzi.

3. Lwaki Abalwadde Beetaaga Byonna High-Resolution Contrast CT NE Contrast Brain MRI/MRV¶

• CT ey’enjawulo ey’obulungi obw’amaanyi ey’obwongo, enzirukanya, n’ennyindo (Thin 1 mm Slices with Bone and Soft-Tissue Windows):
• Eddirisa ly’amagumba likulu eri omusawo w’amagumba n’obusimu: likola maapu y’obulema bwa milimita entuufu obulwadde bw’amagumba we bwalidde okuyita mu emmeeza ey’omu maaso, emmeeza ey’emabega, ne wansi w’enkulungo ey’eggumba ery’omu maaso, era liraga ensengekera y’omulwadde ey’okufuluma kw’omusuwa gw’omu maaso okusobola okulongoosebwa okutambulira.
• Contrast Soft-Tissue Window eraga bulungi ekizimba ekiri wansi w’ekyenyi ekinyweza rim wansi w’omutwe gw’omutwe n’ekizimba kyonna ekinene ekya orbital oba epidural abscess.
• Lwaki CT Yokka Tegimala -> Mandatory Contrast-Enhanced Brain MRI ne DWI ne MR Venography (MRV):
• subdural empyemas ezigonvu ezisooka (naddala ezo ezikwese mu vertikal wakati w’ebitundu ebibiri ebiyitibwa hemispheres okumpi ne falx cerebri / interhemispheric fissure), frontal lobe cerebritis eyasooka, ne superior sagittal sinus thrombosis zisobola okusubwa ku CT scan.
• MRI y'obwongo n'okukuba ebifaananyi ebizitowa mu ngeri ya Gadolinium Contrast ne Diffusion-Weighted (DWI) ye mutindo gwa zaabu: amasira munda mu subdural empyema oba epidural abscess galaga okusaasaana okw’ekitalo okuziyizibwa okumasamasa ku DWI, ate MRV ekakasa oba superior sagittal sinus ya patent oba clotted.

4. Obujjanjabi bw’amatu obugatta ( .ENT) ne Neurosurgical Source Control mu kisenge omulongoosebwa¶

Eddagala eritta obuwuka lyokka teriyinza kuwonya kizimba kya Pott ekifuukuuse; amasira wansi w’ekisenge ky’ekyenyi, munda mu kisenge ky’omu maaso ekizibiddwa, ne munda mu kifo kya epidural/subdural galina okulongoosebwa okuggyibwamu (source control), mu bujjuvu nga ttiimu y’ekiwanga ENT + Neurosurgery mu kiseera kye kimu eky’okubudamya: 1. Okulongoosa ennyindo mu maaso (Draf IIa / IIb or Draf III Modified Endoscopic Lothrop Procedure) ± External Frontal Trephination: Ng’akozesa enkola ya high-definition nasal endoscopes n’okutambulira mu nnyindo okulung’amibwa ebifaananyi, omusawo w’ennyindo aggulawo olutindo olufuluma mu maaso oluzibiddwa nga bugazi okuva wansi, n’anaaba okuva mu nnyindo n’ebiwujjo, n’afulumya ekizimba mu kyenyi ekiri wansi w’olubuto (emirundi mingi nga ayambibwako akawundo akatono akakola ku by’okwewunda eyebrow-incision trephination oba percutaneous needle/drain placement kale tewali nkovu ya kyenyi erabika). 2. Okusengulwa mu kulongoosa obusimu (Burr Hole or Craniotomy) + Okuggyawo eggumba erya Necrotic Bone: Singa epidural abscess, subdural empyema, oba brain abscess ebaawo ku MRI, omusawo alongoosa obusimu akola emergent frontal burr hole oba craniotomy okunaaba okuva mu intracranial pus n’okusalako ebitundu byonna ebifu, ebitaliimu maanyi eby’eggumba ly’omu maaso erya osteomyelitic frontal skull bone (sequestrectomy).

Ennamba z’amangu ez’ekitundu n’ebifo eby’okulongoosa obusimu bw’abaana/abantu abakulu¶

Ekizimba kya Pott ekiteeberezebwa okuba ekifuukuuse kyetaagisa okukyusibwa amangu mu ddwaaliro okugenda mu Tertiary Medical Center oba Dedicated Children’s Hospital nga mulimu essaawa 24 ez’okulongoosa obusimu, Otolaryngology (ENT) Rhinology, Ophthalmology, ne Pediatric/Adult Infectious Diseases coverage:

• United States ne Canada: Kuba 911 okufuna obubonero bwonna obulabula ku busimu, okulaba, oba sepsis, oba genda butereevu mu basomesa abakulu oba Ekitongole ky’amangu mu ddwaaliro ly’abaana. Eddukanyizibwa wansi wa American Academy of Otolaryngology-Okulongoosa omutwe n'ensingo (AAO-HNS), Ekibiina ky'endwadde ezisiigibwa mu Amerika (IDSA), ne Ekitongole ky’Amerika ekikola ku by’abaana (AAP) ebiragiro ebizibu ebikwata ku bulwadde bwa rhinosinusitis obuva ku bakitiriya.

Ebibuuzo ebitera okubuuzibwa¶

Ddala "Pott's puffy tumor" kizimba oba kookolo?¶

Nedda Wadde nga kirimu ekigambo "ekizimba" ekitiisa mu linnya lyakyo, ekizimba kya Pott ekifuukuuse tekirina kakwate konna ku kookolo. Omusawo Omuzungu Sir Percivall Pott bwe yakituuma erinnya mu 1760, ekigambo ky'obusawo eky'Olulattini "ekizimba" kyali kitegeeza butegeeza "okuzimba" kwonna okw'omu kitundu. Ekizimba kya Pott ekifuukuuse (osteomyelitis) obulwadde bw’amagumba (osteomyelitis) mu ggumba ly’ekiwanga eky’omu maaso obukola ensawo y’amasira wansi w’oluwuzi olw’ebweru olw’ekyenyi (ekizimba ekiri wansi w’ekyenyi), nga kisinga kuva ku yinfekisoni y’omusuwa gw’omu maaso obutajjanjabiddwa oba okujjanjabwa ekitundu oba okukubwa mu kyenyi emabegako.

Lwaki abatiini bangi abalina ekizimba kya Pott ekifuukuuse nabo balina ekizimba ekikwese munda mu kiwanga kyabwe okumpi n’obwongo?¶

Ensigo y’omu maaso (frontal sinus) nsawo ya mpewo erimu ebituli munda mu ggumba ly’ekyenyi wakati ddala w’ebisige byo. Ekisenge kyayo eky’omu maaso (ekitunudde mu lususu lw’ekyenyi kyo) ggumba ddene (milimita 2 ku 4), ate ekisenge kyayo eky’emabega (ayawula sinus ku bwongo ne dura mater) kigonvu ng’empapula (milimita 0.5 ku 1). Okugatta ku ekyo, emisuwa egy’ekika kya sipongi nga girina zero one-way valves (the diploic veins of Breschet) gidduka butereevu okuva ku sinus mu maaso okutuuka mu kyenyi n’emabega okutuuka ku kibikka obwongo, ne gituuka ku ntikko y’obunene n’okutambula kw’omusaayi mu kiseera ky’okukula kw’abavubuka. N’olwekyo, obulwadde bwa sinus we buba obw’amaanyi ekimala okusika amasira mu maaso okuyita mu ggumba ddene ery’omu maaso okutuuka ku kyenyi, abalwadde 60 ku 85 ku buli 100 ab’abaana n’abatiini baba bamaze okufuna obuwuka obusala emabega nga buyita mu bbugwe omugonvu ow’emabega oba emisuwa egitalina vvaalu okukola ekizimba ekiyitibwa epidural abscess oba subdural empyema munda mu kiwanga.

Lwaki omulwadde asobola okuba n’ekizimba ky’obwongo ekya epidural oba frontal lobe brain abscess okuva mu kizimba kya Pott ekifuukuuse ate ng’akyatambula n’okwogera mu ngeri eya bulijjo mu kusooka?¶

Ekitundu ky’obwongo eky’omu maaso ennyo ekitudde butereevu emabega w’ekyenyi (the prefrontal cortex of the frontal lobes) tekifuga kutambula kwa mikono n’amagulu, okuwulira oba okwogera, ebitundu ebyo bituula emabega mu bwongo. Abasawo bayita ekitundu ky'omu maaso eky'omu maaso "ekitundu ekisirifu" mu by'obusimu kubanga ensawo y'amasira ekula ng'enyigiriza mu maaso g'ekitundu ky'omu maaso etera okuleeta obunafu bwa zero, okuzirika, n'okwogera okutambula obubi nga bukyali. Mu kifo ky’ekyo, obubonero obusooka okusukka okulumwa omutwe n’omusujja bye bikyukakyuka mu buntu oba embeera y’omuntu mu ngeri etali ya bulijjo: omutiini oba omuntu omukulu okusirika mu ngeri etaali ya bulijjo, obutafaayo, okunyiiga, okwebaka oba okulwawo okuddamu ebibuuzo. Eno y’ensonga lwaki buli mulwadde alina okuzimba mu kyenyi ng’eky’obuwunga afuna CT ey’amangu ey’enjawulo (emergency contrast CT) ne MRI y’obwongo awatali kulowooza ku ngeri ekigezo kye eky’omusingi gye kirabika nga kya bulijjo.

Nsobola ntya okumanya enjawulo wakati w'okunyiga okwa bulijjo okwa "goose-egg" oluvannyuma lw'okukuba omutwe n'ekizimba kya Pott ekifuukuuse?¶

"Eggi lya goose egg" erya bulijjo ery'okulumwa (hematoma) lizimba mu ddakiika ntono ng'okubye omutwe, liwulira nga linywevu oba nga lya kapiira, teririna musujja oba amazzi agafuluma mu sinus, era likendeera buli lukya mu wiiki eddako. Okwawukana ku ekyo, ekizimba kya Pott ekifuukuuse oba kikula mu kiseera ky’obulwadde bw’omusuwa/okunnyogoga okw’amaanyi nga tewali buvune bwonna ku mutwe n’akatono, OBA kirabika oluvannyuma lw’ennaku okutuuka ku wiiki oluvannyuma lw’okukuba mu kyenyi ng’ekiwundu ekiwona kitandika okuddamu okukula mu bwangu, ne kifuuka kyokya, ekimyufu, eky’obuwunga/ekiwujjo, era nga kigonvu nnyo bw’okikwatako, era nga kiwerekerwako okulumwa omutwe mu maaso okukuba, omusujja, oba okuzimba okusaasaana wansi mu bikoola by’amaaso ebya waggulu.

Ekizimba kya Pott ekifuukuuse kisobola okujjanjabibwa n’empeke z’eddagala eritta obuwuka eriweebwa mu kamwa awaka, oba okugikuba amasasi mu ddwaaliro erijjanjaba abantu ab’amangu?¶

Obutasoboka. Eddagala eritta obuwuka eriweebwa mu kamwa teriyinza kuyingira mu ggumba ly’omu maaso erifudde, eririmu obuwuka oba okufulumya ensawo y’amasira essiddwa wansi w’ekisenge ky’ekyenyi, mu butuufu, nga kitundu ku balwadde abazuuliddwa n’ekizimba kya Pott ekifuukuuse baali bamira dda eddagala eritta obuwuka ery’omu kamwa eryalagirwa okukwatibwa obulwadde bwa sinus, ekyenyi kyabwe ne kizimba. Ekikulu kyenkanyi, omusawo ow’amangu talina kusala mu kuzimba mu kyenyi nga tafunye CT ne MRI mu ddwaaliro, kubanga ekizimba kitera okuyungibwa butereevu okuyita mu kinnya mu kiwanga okutuuka ku bwongo obw’ebweru (dura) ne major venous sinus. Obujjanjabi bulijjo bwetaagisa okuweebwa ekitanda mu ddwaaliro, okufulumya amazzi mu kisenge omulongoosebwa mu misuwa n’obusimu nga bigattiddwa wamu, n’okukozesa eddagala eritta obuwuka mu misuwa okumala wiiki 6 ku 8.

Okulongoosa ekizimba kya Pott ekifuukuuse kinaalekawo enkovu ennene okubuna kyenyi?¶

Edda abasawo abalongoosa baalina okusala ekinene mu kyenyi oba ku mutwe okusobola okuggulawo eggumba ery’omu maaso. Leero drain placement tucked right inside the hairs of the eyebrow kale ekyenyi kiwona nga virtually tewali nkovu erabika.
