[Actinomycosis of the central nervous system: a rare complication of cervicofacial actinomycosis].

Central nervous system actinomycosis is a rare but treatable chronic suppurative bacterial infection. The case of a young immunocompetent male with actinomycosis of the CNS is presented. The abscess originated from a primary cervico-facial infection and was located in the left parasellar region. After excision of the mass, that showed Actinomyces colonies, the patient was treated with intravenous Penicillin for 42 days followed by oral administration of the drug for 30 days. After surgery the patient was left with mild sequelae that had improved by the last follow-up, 7 months later. A new CT scan at that time revealed no residual disease or recurrence. The early diagnosis of cerebral actinomycosis relies essentially on a clinical suspicion. Hence it is imperative to be aware of the natural history of this infection and its various modes of presentation.

[Pulmonary actinomycosis--diagnosis and therapy based on past reports of actinomycosis].

A 57-year-old man who complained of bloody sputum was admitted to the hospital because of a spherical mass on a chest X-ray film. Despite a detailed examination, no definitive diagnosis was obtained, and a left lower lobectomy was done. Histopathologic examination of tissue from the resected lobe revealed sulfur granules and branching filamentous bacteria, and therefore pulmonary actinomycosis was diagnosed. Examination of reports published in Japan in the last five years suggested a slight increase in the frequency of diagnosis before treatment of actinomycosis and a slight decrease in the frequency of surgical treatment. However, these changes are not surprising because the frequency of surgical treatment is 58%. These findings suggest that pulmonary actinomycosis should be included in the differential diagnosis of a mass on a chest X-ray film.

Tonsillar actinomycosis: a clinicopathological study.

Actinomycosis has been known to involve virtually every anatomic site in the body. Although actinomycosis has been identified in resected tonsils, its possible role in adeno-tonsillar disease has received little attention. A clinicopathological study of 302 patients who had adeno-tonsillar surgery is presented. Tonsillar actinomycosis was present in 86 (28.5%) patients. The statistical analysis revealed a significant association (P<0.0001) of actinomycosis and tonsillar hypertrophy (56.8%) compared to only 10.3% in the recurrent tonsillitis group. A statistically significant association (P<0.0001) of tonsillar actinomycosis and sickle cell anaemia, beta thalassaemia, bronchial asthma and beta haemolytic streptococcal infections was also seen. This data supports a predisposition of the above conditions to tonsillar actinomycosis and adeno-tonsillar hypertrophy and a possible etiopathologic role of this organism in adeno-tonsillar hypertrophy and disease. Although the clinical association of actinomycosis and tonsillar hypertrophy and beta haemolytic streptococcal infection has been described before the association of actinomycosis with sickle cell anaemia, beta thalassaemia and bronchial asthma is being observed for the first time in literature.

Actinomycosis of the middle turbinate: an unusual cause of nasal obstruction.

Actinomycosis is a rare chronic infectious disease caused by Actinomyces israelii, which is an anaerobic filamentous, gram-positive saprophyte organism of the oral cavity. Historically, these bacteria were known as fungi because of their light microscopic appearance. Actinomycosis consists of three different forms: cervico-facial (the most common form), abdominal and pulmonothoracic. It commonly involves the head and neck region including the mandible, paranasal sinuses, lacrimal gland, parotid gland and orbit. Poor oral hygiene and dental diseases have been known to be the source of actinomycosis. Actinomycosis is diagnosed with positive culture or detecting actinomyces colonies and sulfur granules in histopathologic specimens. The treatment of choice is surgical excision of the lesion and long-term penicillin therapy. Actinomycosis of the internal nose is extremely rare. There was only one nasal septum actinomycosis reported in the English literature, but there was no lateral nasal wall actiomycosis regarding the turbinate. Therefore, actinomycosis should not be overlooked for the differential diagnosis of intra-nasal lesions for the initiation of appropriate and early treatment.

Pediatric cervicofacial actinomycosis.

It is well recognized that cervicofacial actinomycosis is rare in children. We have summarized the cases in the English language literature and reported a recent case from our hospital. In only 10% of clinical situations is actinomycosis the primary diagnosis. Failure to consider actinomycosis in the differential diagnosis of a cervical mass may compromise the ability to make the diagnosis, given the fastidious nature of the most common pathogen, Actinomyces israelii. Indeed, the recovery rate of only 30% in some of the earlier studies of actinomycosis may have been in part due to this oversight. The correct diagnosis, however, is imperative because the treatment of actinomycosis is different from that of routine cervical adenitis in that actinomycosis requires high doses of penicillin over a prolonged time, since it is subject to relapse. Our case serves as a reminder to consider actinomycosis as the possible cause of a cervical mass, not only in adults, but in children as well.

Pelvic actinomycosis presenting as malignant large bowel obstruction: a case report and a review of the literature.

Actinomycosis is an infrequent chronic infectious disease. In most cases the diagnosis is made postoperatively because of its unusual clinical presentation. Moreover, abdominal actinomycosis may mimic cancer, inflammatory bowel disease, or diverticulitis. Delay in diagnosis leading to inadequate management and unnecessary procedures has been reported. We report the case of a 49-year-old woman with large bowel obstruction secondary to extensive pelvic actinomycosis involving the rectosigmoid and cecum. She required emergency surgery, which involved both resection and colostomy. A review of the literature on abdominal actinomycosis during the last 50 years is also reported. Rarely has emergency surgery been described in this condition. Although the incidence of actinomycosis has decreased, the abdominal-pelvic form has been increasing over the past 10 years secondary to increased prolonged use of the intrauterine device. As the clinical spectrum of actinomycosis has dramatically changed, so have the therapeutic considerations. Aggressive surgical management in advanced cases with multiorganic involvement seems to have reemerged in recent years. Consideration of actinomycosis in a woman with prolonged use of an intrauterine device and symptoms of bowel obstruction could help to improve the preoperative diagnosis and management of this rare disease.

[Abdomino-pelvic actinomycosis. Report of 2 cases].

Actinomycosis is a chronic, granulomatous, suppurative and fistulasing infection related to a gram-positive bacteria (actinomyces israeli). Cervico-facial actinomycosis is the most common localization. The prevalence of abdomino-pelvic actinomycosis is increasing mainly with the increase of the use of intrauterin device. Its clinical presentation is variable and may mimic cancer or tuberculosis. The diagnosis of abdomino-pelvic actinomycosis is hard and most of the cases are detected during surgical exploration. We report two cases of abdomino-pelvic actinomycosis; in the first case, the disease was extended to the caecum and the abdominal wall. The skin biopsies made the diagnosis of actinomycosis, avoiding surgery. In the second case, the diagnosis of actinomycosis is made post operatively because of high suspicion of pelvic cancer. Through these two observations, we review pathogenesis of the disease, its clinical aspects and its diagnostic and therapeutic means.
