Anal mycobacterial infections / Infecções micobacterianas do ânus

Abstract Background Mycobacterial infections are a serious public health problem worldwide. Involvement of the anal canal and perineum is very rare, but constitute an important differential diagnosis with other equally serious pathologies that may affect the region, such as malignant neoplasms and Crohn's disease. Objectives To conduct a literature review on mycobacterial infections of the perianal region considering the most recent information for diagnostic and therapeutic guidance of this disease. Methods Research was performed on the PUBMED and LILACS databases with the expressions Mycobacterium, Anal, Infection and Tuberculosis. We reviewed articles referring to series of treated cases, clinical reports and literature review published since 2005. Results Information was compiled on the epidemiology of mycobacterial infections; the clinical behavior of affected individuals; diagnostic options and their validity in clinical practice; and, finally, therapeutic options. Conclusions Mycobacterial infections of the anus and perineum are rare. The most common clinical presentations are the presence of ulceration and fistulization. The diagnosis involves more than one procedure for identifying the bacilli and should consider the presence of manifestations in more than one organ. The treatment is based on pharmacological intervention. Surgery is recommended for acute complications or chronic sequelae of the disease.

Resumo Introdução Infecções micobacterianas constituem um grave problema de saúde pública a nível mundial. As manifestações anoperineais são raras, mas constituem um importante diagnóstico diferencial com outras patologias igualmente graves que podem acometer a região, como as neoplasias malignas e a doença de Crohn. Objetivos Realizar um levantamento da literatura sobre infecções micobacterianas da região anoperineal, considerando as informações mais atuais para orientação diagnóstica e terapêutica dessa enfermidade. Métodos Foi realizada pesquisa nos bancos de dados PUBMED e LILACS com as expressões Mycobacterium, Anal, Infection e Tuberculosis. Foram revisados artigos referentes a séries de casos tratados, relatos clínicos e revisão da literatura publicada a partir de 2005. Resultados Foram compiladas informações sobre a epidemiologia das infecções micobacterianas; o comportamento clínico dos indivíduos afetados; opções diagnósticas e sua validade na prática clínica; e, por fim, opções terapêuticas. Conclusões Infecções micobacterianas da região anoperineal são raras. As apresentações clínicas mais comuns são a formação de ulceras e a fistulização. O diagnóstico envolve mais de um procedimento para identificação dos bacilos, e deve considerar a presença de manifestações em mais de um órgão. O tratamento é principalmente medicamentoso, sendo a cirurgia recomendada nas complicações agudas ou sequelas crônicas da doença.

Intestinal obstruction due to Basidiobolus ranarum: An unusual case.

A case of intestinal obstruction caused by extensive soft tissue fungal infection of the perineum due to Basidiobolus ranarum is presented here. There was excellent response to antifungal treatment. A literature search revealed the case report of intestinal obstruction due to intrinsic mucosal involvement by the fungus, but extensive soft tissue involvement of the perineum resulting in extraneous obstruction to the rectum, has not been reported so far.

Maternal and neonatal screening for Group B streptococci by SCP B gene based PCR: a preliminary study.

OBJECTIVE: To detect the magnitude of group B streptococcal (GBS) colonization and disease among a sample of pregnant women and their infants in Egypt. STUDY DESIGN: Prospective observational study. PARTICIPANTS: The study included 95 pregnant females, 35-37 weeks of gestational age, attending the antenatal outpatient clinic at AlFayom University Hospital between September 2006 and June 2007. All participants were screened with vaginorectal swabs by a conventional GBS PCR assay. Participants were grouped into group A (GBS present, 17 patients) and group B (GBS absent, 78 patients). Details with regard to labor and delivery were recorded and placental pathology was examined to detect histological chorioamnionitis. Ninety-five infant data were also recorded. All neonates of group A (17 out of 95 with known positive maternal GBS) underwent collection of simultaneous specimens from surface sites for PCR before their first bath and within four hours of birth. RESULTS: GBS carriage rate in the study sample was 17.89%. Chorioamnionitis confirmed in three patients by placental pathology (one was in group A and two in group B) was statistically not significant. Twenty-two women had rupture of membranes (< 12 hours) before delivery (four from group A and 18 from group B) that was not statistically significant. There were three infants out of 17 in group A who had GBS colonized at one or more sites by PCR which was statistically significant. However, only one infant was admitted to neonatal intensive care unit (NICU) that was not statistically significant. CONCLUSION: Maternal GBS carriage is associated with a significant increase in neonatal infection rate but is not associated with an increase in neonatal intensive care admission. An accurate evaluation of colonization rate (using a larger sample) is desired to evaluate neonatal invasive disease and determine the cost effectiveness of PCR to select an appropriate preventive strategy in Egypt.

Sistema de aspiración-tracción en el tratamiento de la fasciitis necrotizante del periné / Negative pressure wound therapy for the treatment of perineal necrotizing fasciitis

Introducción: Se discuten 5 pacientes tratados en nuestra institución. Además del aseo quirúrgico con desbridamiento inicial y terapia antibiótica, utilizamos el sistema de aspiración-tracción (SAT) como parte de su tratamiento. Pacientes y métodos: El SAT fue manufacturado artesanalmente con material disponible en el hospital. Después de que el diagnóstico de fasciitis necrotizante del periné fue establecido, todos los pacientes fueron sometidos a aseo quirúrgico y desbridamiento del tejido necrótico. La herida fue cubierta con el SAT quedando a presión negativa bajo aspiración central. Tiempo después, cuando la herida se encontraba limpia y no se requerían de otros aseos quirúrgicos o curaciones bajo anestesia en pabellón, los pacientes fueron sometidos a curaciones locales. En el momento que se logró buen tejido de granulación, se dejó de utilizar el SAT y se continuó con curaciones planas. Cuando la herida empezó a contraerse, aproximamos los bordes con puntos separados de Nylon y dejamos que cerrara por segunda intención. Conclusión: El uso del SAT constituye otra opción válida para el manejo de la herida que deja el aseo quirúrgico y desbridamiento de la gangrena perineal, además provee un mejor manejo de la herida con mayor comodidad para el paciente.

lntroduction: We discuss five patients treated at our institution. Besides the initial surgical debridement and antibiotic therapy, we used the negative-pressure wound therapy (NPVVT) as part of their treatment. Patients and methods: The NPVVT device was constructed with off-the-shelf components. After the diagnosis of perineal necrotizing fasciitis was established, all patients underwent surgical debridement of necrotic tissue. The wound was closed with the NPVVT system and left under negative-pressure central aspiration. After the wound was clean and no more surgical debridements were necessary, patients underwent local treatment. When they achieved granulation tissue, simple dressings were used. When the wound was contracting, we approximated the edges with an interrupted suture of Nylon, and allowed to heal by second intention. Conclusion: The use of NPWT stands as another valid option to manage the wound left after surgical debridement of the perineal gangrene and provides better and more comfortable management of the wound.

Clinical trial of Aromatherapy on Postpartum Mother's Perineal Healing / 간호학회지

PURPOSE: This study was designed to verify the effect of aromatherapy on a postpartum mother's perineal healing. METHOD: The research design was a clinical trial. The methods of aromatherapy were applied sitz bath or soap application using essential oils with Lavender, Myrrh, Neroli, Rose, Grapefruit, Mandarin, Orange, and Roman Chamomile. The subjects of this experiment were postpartum mothers who delivered vaginally with an episiotomy. They were allocated to one of three groups; the aroma-sitz bath group, aroma-soap application group or control group. To evaluate the effect of aromatherapy, the perineal healing status was measured using the REEDA scale and smears of episiotomy wound were obtained. The data were analyzed by repeated measures of ANOVA, ANCOVA, x2-test, and multiple response analysis via SPSS program. RESULT: The REEDA scale was significantly low in the experimental group at postpartum 5th and 7th days (P=.009, P=.003), respectively. Most were observed 'few'(5-10 bacteria per field) bacteria in the smears of episiotomy wound. The one bacteria was identified in the 50.8% of subjects in pretest and two bacteria in the 60.3% in posttest. Most frequently identified bacteria were Escherichia coli and Enterococcus faecalis. CONCLUSION: In conclusion, these findings indicate that postpartum aromatherapy for perineal care could be effective in healing the perineum perineal care could be effective in healing the perineum.
