The evaluation of bacteriology in perianal abscesses of 81 adult patients

OBJECTIVE: Treatment of perianal abscesses requires prompt surgical drainage and antimicrobial therapy. However, we should encourage the selective use of antimicrobial agents on a case-by-case basis, especially because there is no evidence that uncomplicated perianal abscesses can be safely treated only with drainage. For this reason, it is important to identify the causative organisms; therefore, we accessed the microbiological analysis of these patients. PATIENTS AND METHODS: In this study, 81 consecutive adult patients with perianal abscesses, who presented at a university hospital in Diyarbakir from January 2004 to December 2006, were included. Clinical and laboratory data, and results of microbiological analysis were recorded. RESULTS: All specimens, except seven, yielded bacterial growth. Escherichia coli, Bacteriodes spp., coagulase-negative Staphylococci, and Staphylococcus aureus were the most common isolated organisms. CONCLUSION: In contrast to other investigators, this study demonstrated that aerobic organisms are the predominant isolates in these infections.

Ulceración perianal: Dos casos de una rara manifestación de tuberculosis extrapulmonar / Perianal tuberculosis: Report of two cases

Perianal tuberculosis is an uncommon variant of extra pulmonary tuberculosis and mimics other common perianal conditions. We report two patients with perianal tuberculosis. An 82-year-old male presenting with purulent perianal discharge and weight loss. A pelvic magnetic resonance imaging showed a low trans sphincteric anorectal fistula with abscess formation. A fistulectomy was performed and the pathological study showed a granulomatous-tuberculous chronic inflammation. Mycobacteria were recovered from gastric contents. A 48-year-old male with the same symptoms. An ulcerated lesion in the anal region was biopsied, disclosing a granulomatous inflammatory process with Ziehl-Nielsen stainable organisms.

Anorectal abscesses: bacterial isolation and antimicrobial resistance

A total of 68 cases of pus or pus swabs were received at the laboratory of Abbasi Shaheed Hospital, Karachi from anorectal absecesses. They were collcted from 1993 to 1996. All samples were subjected to culture of which 53 [77.94%] showed growth. The organisms isolated from positive sample were Escherichia coli 22 [41.51%], Staphyloccus aureus 19 [35.85%], Staphyloccus epidermidis 4 [7.55%], Proteus vulgaris 3 [5.66%], Pseudomonas aeruginosa 3 [5.66%] and Streptococcus pyogenes 2 [3.77%]. Different antibiotic sensitivity and resistance patterns were found for different organisms. There was increased antimicrobial resistance observed in the present study. Proper identification, isolation and sensitivity pattern of organism is essential for successful treatment besides adequate dosage of antibiotics for appropriate duration of time By using this methodology we will decrease the chances of drug resistance in our population

Enfermedad estreptocócica perianal y psoriasis gutata: a propósito de dos casos infantiles / Perianal streptococcal disease and psoriasis guttata: a propos of 2 infantile cases

Se presentan dos casos infantiles de psoriasis gutata y eritema perianal persistente donde se aisló el estreptococo beta hemolítico del grupo A. Se quiere recalcar la importancia de buscar el reservorio perianal del estreptococo en el niño con psoriasis en gotas, además de los clásicos focos faríngeos y nasales. El tratamiento empleado fue penicilina V oral (100.000 U/kg/d) durante 3 semanas más rifampicina (20 mg/kg/d) durante 10 días por la persistencia clínica del eritema perianal y la positividad del cultivo. La duración del tratamiento está determinada por la remisión del cuadro clínico y la negativización de los cultivos perianales
