Diagnosis and Management of Candida of the Nipple and Breast

Candida guilliermondii as an agent of postpartum subacute mastitis in Rio de Janeiro, Brazil: Case report

Candida spp. can cause mild-to-severe human infections. Certain species have been described as the etiologic agent of human mastitis, inflammation of the breast tissue. Mastitis affects millions of lactating women and can be a source of disease transmission to the infant. In this work, we report the detection of the unusual etiologic agent of human mastitis, Candida guilliermondii, isolated from the milk of a puerperal woman with subacute mastitis in Rio de Janeiro, Brazil. Species identification was performed by MALDI-TOF MS and genetic sequencing. The patient had a full recovery after antifungal therapy.

New perspectives on the topical management of recurrent candidiasis

Candidiasis is a common opportunistic infection caused by fungi of the Candida genus that affects mainly mucocutaneous tissues (e.g., vaginal, oral, and mammary). This condition has been known for a long time; thus, innumerous topical and systemic treatments are already available on the market worldwide. Yet, recurrent superficial candidiasis (RSC) is an expected outcome, still lacking effective and convenient treatments. Although several individual conditions may contribute to disease recurrence, biofilms' presence seems to be the main etiological factor contributing to antifungal resistance. More than proposing novel antifungal agents, current research seems to be focusing on improving the pharmaceutical technology aspects of formulations to address such a challenge. These include extending and improving intimate contact of drug delivery systems with the mucocutaneous tissues, increasing drug loading dose, and enhancing topical drug permeation. This review discusses the current understanding of the RSC and the use of pharmaceutical technology tools in obtaining better results. Even though several drawbacks of conventional formulations have been circumvented with the help of nano- or microencapsulation techniques and with the use of mucoadhesive formulation excipients, many challenges remain. In particular, the need to mask the unpalatable taste of formulations for the treatment of oral candidiasis, and the necessity of formulations with a "dryer" sensorial feeling and improved performances in providing higher bioavailability for the treatment of mammary and vaginal candidiasis.

Mastitis While Breastfeeding: Prevention, the Importance of Proper Treatment, and Potential Complications

Mastitis is an inflammation in the breast, which may involve a bacterial infection. Breast infection during breastfeeding is a common phenomenon that requires immediate and appropriate treatment. Without proper treatment, inflammation may lead to the cessation of breastfeeding. Another potential complication is the development of an abscess. Based on the nutritional and immunological value of breast milk, the recommendations of the American Academy of Pediatrics (AAP) and the World Health Organization (WHO) is exclusive breastfeeding up to 6 months of age, followed by continued breastfeeding as complementary foods are introduced, with continuation of breastfeeding for 1 year or longer as mutually desired by mother and infanRecent meta-analyses indicate breastfeeding protects against childhood infections, allows for a possible increase in intelligence, and for a reduction in overweight and diabetes. Breastfeeding is beneficial for nursing women as well. It is therefore important to help the mother overcome difficulties such as mastitis and to continue breastfeeding. The choice of a proper treatment and the provision of therapeutic instructions to the patient are crucial for a cure, for a successful duration of breastfeeding, and for preventing complications for mother and baby. In this article, we provide the latest clinical guidelines regarding drug treatment and supportive therapy in mastitis. We also discuss the latest guidelines of candida treatment, as candida infection may develop as a result of antibiotic therapy. Overall, improperly treated mastitis may cause the premature cessation of breastfeeding, and will cause suffering to both mother and baby; giving proper treatment and instructions to the mother are hence of the utmost importance.

Skin diseases of the breast and nipple: Inflammatory and infectious diseases

Certain dermatologic conditions are unique to the breast and nipple, whereas others may incidentally involve these structures. All require a nuanced approach to diagnosis and treatment because of the functional, sexual, and aesthetic importance of this area. The lactating patient requires special management because certain treatment options are contraindicated. All dermatologic conditions involving the breast and nipple require careful evaluation because malignancy of the breast can be mistaken for a benign condition or may trigger the development of certain dermatologic conditions. The second article in this continuing medical education series reviews common and uncommon inflammatory and infectious conditions of the breast and nipple and provides insight into both the diagnosis and the treatment of this heterogeneous group of diseases. For the purposes of this article, these conditions are divided into 4 distinct categories: 1) dermatitis; 2) radiation-induced changes; 3) mastitis; and 4) miscellaneous dermatologic conditions of the breast and nipple.

Dermatoses of the breast in lactation

Dermatoses of the breast during lactation can be difficult to diagnose because of their overlapping clinical appearances. It is important to properly diagnose and treat nipple dermatitis since it can be a significant source of pain when nursing. Poorly controlled nipple pain in nursing mothers is one of the primary reasons for breastfeeding to be discontinued earlier than is recommended. Therefore, it is relevant for practicing dermatologists to be aware of certain facts in a patient's history, specific physical exam findings, and the most appropriate laboratory tests used to diagnose these conditions. In addition, the therapeutic approach should be effective and safe for the mother and infant. This review article provides dermatologists with a detailed discussion on the clinical features and management of various breast dermatoses seen in lactation, including atopic dermatitis, irritant contact dermatitis, allergic contact dermatitis, psoriasis, bacterial infections, yeast infections and herpes simplex virus infections.

Caring for new mothers: diagnosis, management and treatment of nipple dermatitis in breastfeeding mothers

Breastfeeding is thought to be the most optimal form of infant nutrition. Nursing mothers are generally advised to continue breastfeeding until the infant is two years of age or beyond. Unfortunately, however, a majority of nursing mothers will discontinue breastfeeding much earlier than recommended. The most common reason for early discontinuation of breastfeeding is nipple pain. It is, therefore, essential that dermatologists know how to appropriately diagnose and effectively treat nipple pain associated with nipple dermatitis among nursing mothers. This review article provides a detailed discussion on the clinical features and management of various causes of nipple dermatitis during lactation, including problems with infant latch-on, congenital oral anomalies, plugged lactiferous ducts, atopic dermatitis, irritant contact dermatitis, allergic contact dermatitis, yeast infections, bacterial infections, herpes simplex virus, and Raynaud's phenomenon of the nipple.

Results of microbial testing exploring the etiology of deep breast pain during lactation: a systematic review and meta-analysis of nonrandomized trials

INTRODUCTION

Controversy over the etiology of deep or burning breast pain during lactation continues to persist, despite a long history of published studies and case reports. This article reviews the literature exploring the etiology of deep breast pain, summarizes the results, and identifies possible explanations for the controversies surrounding this disorder.

METHODS

A clinical query and a librarian-assisted search of MEDLINE were used to find articles published between 1896 and 2010. Inclusion criteria consisted of comparing microbial testing results from symptomatic and asymptomatic lactating women. Cases were restricted to those experiencing deep or burning breast pain when possible.

RESULTS

Prospective studies consisting of 1 unmatched case-control and 6 cohorts were found. Trials typically detected higher microbial levels in the milk or nipple(s) or both of symptomatic women, irrespective of the detection method or type and range of microbes (bacterial, yeast, or fungal) studied. Case milk samples were positively associated with finding Staphylococcus aureus (relative risk ratio [RR] 7.29; 95% confidence interval [CI], 3.25-16.36) or Candida (RR 8.45; 95% CI, 3.96-18.06). Moreover, recent reports about small-colony variants and biofilm-producing organisms may explain the atypical symptoms unique to this disorder.

DISCUSSION

In lactating women reporting deep breast pain, evidence consistent with infection is persistently found, and explanations exist for the disorder's atypical characteristics. Although lactating women with deep breast pain are more likely to test positive for Candida, the risk of testing positive for S aureus is also present. Thus, these women should have cultures done. Management options include treating immediately while awaiting results or waiting until results are available to guide treatment. With either approach, providers must consider the risk of falsely negative tests.

Bacterial analysis of breast milk: a tool to differentiate Raynaud's phenomenon from infectious mastitis during lactation

Lactational Raynaud's syndrome may be misdiagnosed as infectious mastitis on the basis of the breast pain. The objective of this work was to elucidate if microbiological analysis of milk may contribute to the differentiation of both conditions. Ten lactating women clinically diagnosed by Spanish lactation consultants were included in the study. Of these, five suffered from mastitis and the remaining five suffered from Raynaud's syndrome. Breast milk samples were inoculated on diverse culture media. Seventy isolates were selected and identified by 16S rDNA PCR sequencing. Parallel, PCR-DGGE and quantitative real-time PCR were used to assess the presence of bacterial DNA in the samples. Neither bacteria nor yeasts could be detected in the milk samples provided by the women suffering from Raynaud's syndrome. In contrast, large numbers of bacteria were isolated from those with infectious lactational mastitis. Globally, the levels of bacterial DNA were significantly higher in the milk of mastitis-suffering women. Bacteriological analysis of milk can be an useful tool to facilitate the differential diagnosis between the infectious mastitis and Raynaud's syndrome during lactation.

The yeast connection: is Candida linked to breastfeeding associated pain?

OBJECTIVE

The objective of the study was to determine whether the isolation of Candida from breastfeeding women is associated with self-reported pain.

STUDY DESIGN

A prospective cohort study was conducted from May 2004 to July 2006. Ninety-eight breastfeeding women were enrolled: 20 women reported breastfeeding associated pain, and 78 women were asymptomatic. Cultures were obtained from breast milk, areolae, and infants' oropharynx.

RESULTS

Six of the 20 symptomatic women had breast milk cultures positive for yeast, compared with 6 of 78 controls (30% vs 7.7%, P = .015). Among the 12 women from whom yeast was isolated, 11 grew Candida albicans. Incidence of Staphylococcus aureus isolation did not differ significantly between groups (5 of 20 vs 15 of 78, P > .05).

CONCLUSION

C. albicans is found more often in breastfeeding mothers who report pain as compared with asymptomatic breastfeeding mothers. Further studies, including treatment trials, are needed to determine whether Candida plays an etiologic role in breastfeeding associated pain.
