1/115. endocarditis due to Acinetobacter lwoffi on native mitral valve.

    endocarditis due to Acinetobacter is a rare pathology with high mortality, reported mainly in hospitalized patients with predisposing risk factors. This is the second case of endocarditis due to Acinetobacter reported in our country in the last 10 years. ( info)

2/115. Acinetobacter meningitis: four nosocomial cases.

    We report the clinical features and therapeutic outcomes of four patients with multiantibiotic-resistant Acinetobacter meningitis. There were three males and one female, aged from 17 to 49 years. Three of them had suffered from head injuries with skull fractures, and the other suffered from an intracerebral hemorrhage and underwent a craniotomy. All four patients acquired nosocomial Acinetobacter meningitis, and multiantibiotic resistance developed. After treatment with imipenem/cilastatin, three of the four patients survived; one died of multiorgan failure. Because the clinical manifestations of Acinetobacter meningitis are similar to those of other gram-negative bacillary meningitis, the diagnosis can only be confirmed by bacterial culture. Resistance to multiple antibiotics, including third-generation cephalosporins, is frequently seen in patients with nosocomial Acinetobacter meningitis, and imipenem/cilastatin seems to be the antibiotic of choice for this potentially fatal central nervous system infection.

3/115. Pulmonary infiltrates in an elderly man.

    An 80-year-old man presented with subjective fever, chronic cough occasionally producing scant yellow sputum, retrosternal pleuritic pain, and dyspnea on walking one block. Since symptom onset three months earlier, he had lost 20 pounds; he had had two loose stools a day, fatigue, malaise, and anorexia but not hemoptysis, nausea, vomiting, hematemesis, hematochezia, or melena. He denied paroxysmal nocturnal dyspnea or orthopnea. As far as could be ascertained, he not recently been exposed to tuberculosis or any other infectious disease. He had previously been seen at another clinic and had completed a 10-day trial of erythromycin (500 mg p.o. q12 h) without apparent change in symptoms. ( info)

4/115. Pathophysiology of surgical site infection in total hip arthroplasty.

    This article is a case report of a 69-year-old man who underwent a right total hip replacement procedure and developed a surgical site infection. Areas of concern in prevention and treatment of hip arthroplasty infection are presented, focusing on the pathophysiologic process involved. A review of the patient risk factors and the pathophysiologic action potentiating risk for infection include host immunity, nutritional status, diabetes, age, use of steroids or immunosuppressive drugs, rheumatoid arthritis, and urinary tract or other infections. The case report identifies the patient's age, multiple instrumentation of the bladder resulting in bacteriuria and the reinfusion of 400 cc of autologous shed blood via cell saver, a controversial risk subject, as the primary risk factors for surgical site infection in this patient. Readmission to the hospital on day 16 after the operation was completed on identification of 2 pathogenic organisms, methicillin-resistant staphylococcus aureus and acinetobacter calcoaceticus bio anitratus. The infection was successfully treated with oral ciprofloxacin and intravenous administration of tobramycin, preventing progression from superficial to deep infection and preserving the prosthesis.

5/115. Postoperative endophthalmitis caused by sequestered acinetobacter calcoaceticus.

    PURPOSE:To describe postoperative endophthalmitis caused by sequestered acinetobacter calcoaceticus.METHOD:Case report. A 40-year-old woman developed recurrence of inflammation after extracapsular cataract extraction with intraocular lens (IOL) implantation. At last recurrence, the capsular bag was studded with white deposits. Intraocular lens was removed along with capsular bag during pars plana vitrectomy.RESULTS:The capsular bag, when cultured, grew A calcoaceticus. The media remained clear with no evidence of recurrence of infection over a 3-month follow-up. CONCLUSION:Postoperative endophthalmitis similar to that caused by sequestered propionibacterium acnes can be caused by A calcoaceticus. ( info)

6/115. Acinetobacter meningitis following head trauma.

    A case of acinetobacter meningitis following head injury in a patient who developed cerebrospinal fluid otorrhea, and did not have any neurosurgical procedure, is presented. Previously reported cases are cited, with a review of the literature. pefloxacin monotherapy is associated with a poor clinical response. ( info)

7/115. acinetobacter calcoaceticus pneumonia and the formation of pneumatoceles.

    Pneumatoceles are cystic lesions of the lungs often seen in children with staphylococcal pneumonia and positive-pressure ventilation. acinetobacter calcoaceticus is an aerobic, short immobile gram-negative rod, or coccobacillus, which is an omnipresent saprophyte. The variant anitratus is the most clinically significant pathogen in this family, usually presenting as a lower respiratory tract infection. Acinetobacter has been demonstrated to be one of the most common organisms found in the ICU. We present three critically ill surgery patients with Acinetobacter pneumonia, high inspiratory pressures, and the subsequent development of pneumatoceles. One of these patients died from a ruptured pneumatocele, resulting in tension pneumothorax. Treatment of pneumatoceles should center on appropriate intravenous antimicrobial therapy. This should be culture directed but is most often accomplished with imipenem. Percutaneous, computed tomographic-guided catheter placement or direct tube thoracostomy decompression of the pneumatocele may prevent subsequent rupture and potentially lethal tension pneumothorax.

8/115. corneal perforation due to Acinetobacter junii: a case report.

    Acinetobacter spp. is emerging as a common cause of nosocomial infections. Community acquired ocular infections due to Acinetobacter are rare. Only one case of perforation of cornea has been reported previously, where old nomenclature was used to describe the causal agent. We report a case of corneal perforation due to Acinetobacter junii for which a therapeutic penetrating keratoplasty was conducted and the patient eventually recovered. ( info)

9/115. Rathke's cleft cyst abscess.

    Pituitary abscesses are rare. Occasionally they will arise in pre-existing pituitary pathology. We report such an occurrence within a Rathke's cleft cyst. On the basis of history and imaging, this was indistinguishable from more commonly encountered pituitary pathology. ( info)

10/115. Community-acquired Acinetobacter meningitis in adults.

    Community-acquired Acinetobacter meningitis in adults is an extremely rare infection of the central nervous system (CNS). Here we report one adult case of this rare CNS infection and review the clinical data of another seven cases reported in the English language literature. In total, eight patients (six men and two women) aged between 19 and 63 years were studied.The causative pathogen in our patient was acinetobacter baumannii; in the other reported cases they were most likely Acinetobacter Iwoffii, Acinetobacter johnsonii, Acinetobacter junii, a genomic species 3 or 6. No underlying disease was found in seven of the eight cases and six of the eight patients acquired the infections before the age of 30 years. fever and consciousness disturbance were the most common clinical manifestations. waterhouse-friderichsen syndrome (WFS) was found in two cases. Unlike the Acinetobacter strains found in nosocomial infections, the strain of Acinetobacter meningitis in the community-acquired case did not show multiple antibiotic resistance. Most adult patients with community-acquired Acinetobacter meningitis can be saved by timely therapy with appropriate antibiotics before deterioration of the systemic condition and impairment of consciousness.
