1/7. F-18 FDG uptake in breast infection and inflammation.PURPOSE: Whole-body fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET) scanning has been useful in the management of breast cancer. However, F-18 FDG uptake sometimes has been associated with benign breast disease. Four cases are reported of F-18 FDG breast uptake caused by infectious or inflammatory mastitis that mimics malignant disease. methods AND RESULTS: Two women had F-18 FDG whole-body scans for the evaluation of a large breast mass after inconclusive results of ultrasonography. In both cases, intense focal F-18 FDG breast uptake was noted that mimicked breast cancer. Histologic examination showed, in one patient, chronic granulomatous infiltration that likely represented tuberculous mastitis, because she showed a good clinical response to empirical anti-tuberculous treatment. The second patient had lactational changes associated with acute inflammation, and the culture grew Staphylococcus aureus. The breast mass completely disappeared 3 weeks after a course of antibiotic treatment. The other two patients had staging F-18 FDG PET scans 1 and 12 months after lumpectomy for breast carcinoma to detect residual, recurrent, or metastatic disease. Both scans showed a ring-like uptake in the involved breast, with superimposed intense focal uptake suggesting tumor necrosis centrally and malignant foci peripherally. In both cases, histologic examination revealed hemorrhagic inflammation secondary to postsurgical hematomas and no evidence of malignancy. CONCLUSION: Acute or chronic infectious mastitis and postsurgical hemorrhagic inflammatory mastitis should be considered in patients who have a breast mass, especially those with a history of tenderness or surgery.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
2/7. Breastfeeding and Staphylococcus aureus: three case reports.This paper presents three case reports of breastfeeding women with Staphylococcus aureus (S. aureus) infections. The first case is a woman who developed recurrent staphylococcal skin infections, misdiagnosed as a fungal infection by her caregivers. The second case is a woman who experienced recurrent mastitis following a severe wound infection in her caesarean section scar; both she and her baby were carriers of S. aureus. The third case is a woman who experienced mastitis and a breast abscess, while her baby and other members of the family developed recurrent boils and skin infections with a methicillin-resistant S. aureus (MRSA). A wide range of staphylococcal infections may occur in the postpartum period: mastitis, abscess, caesarean scar infection, boils and skin infection. Some cases of recurrent infections may be related to nasal carriage in mother or infant. microscopy can be useful in differentiating bacterial infections from fungal infections and confirming nasal carriage. When mothers or infants are nasal carriers of Staphylococci health professionals may recommend nasal mupirocin (Bactroban) and bathing with antiseptic washes to reduce recurrent staphylococcal infections.- - - - - - - - - - ranking = 8keywords = aureus (Clic here for more details about this article) |
3/7. Isolation of enterococcus faecalis from a case of nonpuerperal breast abscess.Nonpuerperal breast abscess (NPBA) has different etiology as compared to the mastitis occurring in post partum women. The condition presents either as acute suppurative infection or chronic type. Organisms usually implicated are Staphylococcus aureus, coagulase negative staphylococci, and anaerobes. Mostly the infection is polymicrobial in nature. Herein, we report the isolation of enterococcus faecalis from a case of acute suppurative NPBA.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
4/7. Transmission of community-associated methicillin-resistant staphylococcus aureus from breast milk in the neonatal intensive care unit.methicillin-resistant staphylococcus aureus (MRSA) has become increasingly common in neonatal intensive care units and can lead to severe outcomes. Baby C, of a set of quadruplets, died of MRSA sepsis. The surviving siblings were colonized with MRSA. Expressed breast milk was fed to all infants; tested breast milk samples were all MRSA-positive. Pulsed field gel electrophoresis results of isolates from the infants and breast milk were indistinguishable.- - - - - - - - - - ranking = 5keywords = aureus (Clic here for more details about this article) |
5/7. Methicillin-resistant staphylococcal mastitis.A postpartum patient had a unilateral breast infection that responded to cephalosporin treatment. During therapy, the contralateral breast developed a methicillin-resistant staphylococcus aureus infection. The patient was hospitalized and treated successfully with intravenous vancomycin. Obstetricians should be alert to this possibility when treating patients with postpartum mastitis.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
6/7. mastitis and toxic shock syndrome.Toxic shock syndrome (TSS) secondary to mastitis or breast abscess is only seldom described. We report a case of definite TSS due to postpartum staphylococcal mastitis which evolved over a period of 3 weeks to a breast abscess, recurring after 2 months. Only the episode of acute mastitis was complicated with TSS, while Staph. aureus could be isolated during the period of mastitis from milk and during drainage of the second breast abscess.- - - - - - - - - - ranking = 1keywords = aureus (Clic here for more details about this article) |
