    Urethritis Urethritis Presentation Transcript

    • Dr. Shilpa Soni MGMCH
    •  medial horizontal gp of Inferior vena superficial cava inguinal LN
    •  Superficial Inguinal LN - Penile skin - Scrotal skin  Deep inguinal LN - Anterior male urethra & glans penis - Vulva - Vagina, lower third - Uterus, lower part - isthmus of fallopian tube  Sacral LN - Vulva - Cervix
    •  Iliac LN  Pre & para aortic group of LN - Posterior urethra - Testes & epididymis - Vulva - Uterus, upper part - Upper third & middle third vagina - Ovaries - Cervix - Fallopian tubes - Prostate - Cervix
    • Urethritis Inflammation of the urethra. Discharge +/- dysuria or may be asymptomatic.
    • Causes of urethritis  Infectious causes- - Gonococcal – Neisseria gonorrhoea (50-90%) - Non gonococcal – - Chlamydia trachomatis. (20-50%) - Ureaplasma urealyticum. (20-80%) - Mycoplasma genitalium. (10-30%) - Trichomonas vaginalis. (1-70%) - Yeast. - HSV.
    •  Non Infectious Causes - Trauma - Urethral stricture. - Catheterization. - Chemical irritants. - Dehydration.
    • Gonococcal Urethritis 1. N gonorrhoea – gram negative, non motile, non spore forming diplococci. 2. Oxidase positive 3. Ferments glucose 4. PPNG – penicillinase produc- - ing N. gonorrhoea: cefotaxime, ceftriaxone, ciprofloxacin, tetrac-ycline can be used.
    •  N gonorrhoea – present predominantly intracellularly in the polymorphonuclear leucocytes (PMN).  Penetrates columnar epithelium.
    •  Structure – - capsule – polyphosphate - trilaminar membrane – outer membrane – type 1 protein (por) - A &B - type 2 protein(Opa pro) - RMP protein - peptidoglycan – muramic acid & N-acetyl glucosamine. - cytoplasmic membrane – penicillin binding proteins. - Pili - filaments
    •  Strains - Pathogenic strains – N. gonorrhoea - N. meningitidis - Non pathogenic strains – N. catarrhalis - N. pharyngis sicca - N. lactamica - N. subflava
    • Clinical features :  Affects urethra in both sexes.  Transmission – sexual contact  Incubation period – 2-5 days  Intense burning sensation.  Fever & malaise.
    •  In men anterior urethritis is more common.  Discharge – profuse, purulent & yellowish green.  15% males – mild or asymptomatic.
    •  Complications – - Posterior urethritis - Epididymitis - Acute or chronic prostatitis - Untreated – periurethral abscess & watercan perineum.
    •  In females – 90% infection  50% of infected females are asymptomatic.  Primary site - endocervical canal  Symptoms of urethritis includes - Discharge - scanty, mucopurulent cervical discharge. - Vaginal pruritus - Dysuria
    •  Proctitis through autoinoculation from cervical discharge or as a result of direct contact from an infected partner’s penile secretions.
    •   Complications in femalesPID Tubo ovarian abscess Subsequent ectopic pregnancies Chronic pelvic pain Infertility Fitz-Hugh-Curtis syndrome – inflammation of liver capsule associated with genitourinary tract infection. Present in upto ¼ of women with PID caused either by N. gonorrhoea or C. trachomatis.
    •  Complications common to both sexes - - Disseminated gonococcal infection (DGI) - Acute arthritis-dermatitis syndrome – acute arthritis, tenosynovitis, dermatitis or combination of these findings. - Gonococcal arthritis - Meningitis - Endocarditis
    •  Laboratory diagnosis – - Microscopy – gram staining - gram negative diplococci
    •  Culture – thayer martin medium - chacko nayer medium - martin lewis media - new york city media
    •  PCR  DNA hybridisation  ELISA  The complement fixation  Latex agglutination immunofluoroscence & anti surface pili assays  Radioimmunossay  Immunoblotting
    •  - Treatment – uncomplicated gonorrhoea Cefixime 400 mg stat or Ceftriaxone 125 mg stat IM or Ciprofloxacin 500 mg stat or Ofloxacin 400 mg stat or Levofloxacin 250 mg stat + If chlamydia infection is not ruled out - Azithromycin 1 gm stat or - Doxycycline 100 gm BD for 7 days.
    •  Treatment – DGI - Ceftriaxone 1 gm IM or IV every 24 hrs or - Cefotaxime 1 gm IV every 8 hrly or - Ciprofloxacin 400 gm IV every 12 hrs or - Ofloxacin 400 gm IV every 12 hrs or - Levofloxacin 250 gm IV daily. or - Spectinomycin 2 gm IV every 12 hrly.
    • Non gonococcal urethritis
    • CHLAMYDIA TRACHOMATIS  C. trachomatis – gram negative obligate intracellular micro organism that preferentially infect squamo-coloumnar epithelium.  Based on monoclonal antibody assay – 18 serological variants. - A, B, Ba & C – trachoma. - D-K – genital tract infections. - L1 – L3 – LGV
    •  Two functional & morphological forms- Elementary body – infectious but metabolically inert. - Reticulate body – metabolically active but non infectious.  The intracellular bacteria rapidly modify their membrane bound compartment into chlamydial inclusion to prevent the phagosome lysosome fusion.
    •  Clinical features – - Incubation period – 1 - 3 weeks. - Low grade urethritis with scanty or moderate mucoid or mucopurulent urethral discharge & variable dysuria. - Subclinical urethritis are also common.
    •  In men- Sites of infection are – urethra. - epididymis. - systemic. - Clinical syndrome – urethritis, post gonococcal urethritis & Reiter’s disease.
    •  Urethritis – - Dysuria with mild to moderate whitish or clear urethral discharge. - On examination – focal urethral tenderness - meatal or penile lesions may mimic herpetic urethritis.
    •  Epididymitis – recurrent infections - Unilateral scrotal pain, Swelling & Tenderness. - Fever - Urethritis may often be assymptomatic & evident only as urethral inflammation.
    •  Prostatitis – - Ususaly asymptomatic or may - Presents with discomfort on passing urine & vague pain in perineum, groins, thighs, penis, suprapubic region or back. - Painful ejaculation.
    •  Proctitis – repetitive anal intercourse or by lymphatic spread from posterior urethra. - Rectal pain - Discharge - mucopurrulent - Bleeding
    •  Reiter’s syndrome – urethritis - conjuctivitis - arthritis - characteristic mucocutaneous lesions as well as psoriasis such as circinate balanitis & keratoderma blenorrhagicum. Reactive arthritis is RF seronegative, HLA-B27 linked arthritis often precipitated by genitourinary or gastro intestinal infections usually after 2-3 weks of infection.
    •  Organisms associated with Reiter’s syndrome are - N. gonorrhoea - C. trachomatis - U. urealyticum - Salmonella - Shigella - Campylobacter  Treatment – antibiotics, NSAIDS, sulfasalazine, corticosteroids & immunosupressants.
    •  In women – - Cevicitis – mucopurulent cervical discharge - cervical erythema & edema with an area of ectopy - spontaneous or easily induced cervical bleeding - Urethritis – dysuria - frequency - pyuria
    • - Bartholoinitis - Endometritis – abnormal vaginal bleeding - menorrhagia - metrorrhagia - PID – lower abdominal pain - adenexal tenderness on pelvic examination - MPC often present - Perihepatitis (Fitz-Hugh-Curtis Syndrome)
