Management of lactating breast abscesses by ultrasound-guided needle aspiration and continuation of breastfeeding: A pilot study.

INTRODUCTION: Needle aspiration of breast abscesses during lactation are currently recommended as an alternative to surgery only for moderate forms. In case of breast abscess, many patients stop breastfeeding on the advice of a health professional. We reviewed our experience of treatment of lactating breast abscesses by ultrasound-guided aspiration and suggest an algorithm of their management. We also analyzed the continuation of breastfeeding of these patients after advices from trained teams. MATERIEL AND METHODS: We conducted a retrospective study from April 2016 to April 2017, including 28 patients referred for a breast abscess during lactation at the Duroc Breast Imaging Center. A management by ultrasound-guided aspiration was proposed to each patient. We collected data about the breastfeeding between October 2018 and January 2019. RESULTS: A single aspiration was sufficient in 64.3% of cases. The delay between the occurrence of the abscess and the indication for drainage was significantly higher for patients who have needed finally surgical drainage (p = 0,0031). There were no difference of size of abscesses between patients receiving needle aspiration alone and those who have undergone surgery (p = 0,97). All patients who had been managed by needle aspiration continued breastfeeding after the treatment and 40% of the patients were still breastfeeding at 6 months. CONCLUSION: The management of lactating breast abscess by ultrasound-guided needle aspiration is an effective alternative to surgery. It appears to be effective regardless of the size of the abscess and is compatible with the continuation of breastfeeding. Our study has indeed shown that if they are well advised, the majority of patients continue breastfeeding so that it is essential that health professionals be better trained regarding the management of breastfeeding complications.

[Guidelines for multivitamin administration in fortified human milk prepared for preterm infants]. / Protocole d'administration de l'Uvestérol ADEC® au prématuré nourri au lait de femme enrichi.

BACKGROUND: To reach nutritional standards, human milk has to have 2g/dL of protein. In 2013, Lafeber stated that when human milk is fortified up to 2g/dL, it may increase its osmolality up to 500 mOsm/kg. He also warned that care must be taken when adding a drug or vitamins to human milk. AIM: We studied, for the first time, the impact of adding multivitamins (ADEC) on human fortified milk osmolality. METHOD: The osmolality of 36 pasteurized, fortified human milk samples was measured. The amount of milk required as a solvent to maintain osmolality below 500 mOsm/kg was then determined. RESULTS: The osmolality of 2mL of fortified human milk reached up to 750 mOsm/kg when the multivitamins ADEC was added. The osmolality decreased proportionately as the solution was diluted and if vitamins are added in two half-doses each time. It is only with 20mL of milk that the osmolality lowers to its initial rate of 430 mOsm/kg. The stronger the milk's fortification is, the greater impact it has on the milk's osmolality. CONCLUSION: New nutritional recommendations for premature infants are needed. In the meantime, when the fortified milk intake is under 20mL, it is preferable to extend parenteral intakes with fat-soluble vitamins or reduce doses of vitamins in milk. Also, we should use enriched human milk as a fortifier and be cautious with indiscriminate fortification or when adding drugs and electrolyte solutions.
