Cysts of the same type were found in 57.7 % of patients (concordant group). Such a finding suggests that in patients bearing multiple cysts, all aspirated fluids need to be classified on the basis of their cationic composition. In the concordant group, type 1 cysts were more frequent than in the discordant group (80.3 % vs 59.5 %, P = 0.002). High K+\/Na+ ratios (&gt; 4.0) were present in 64 % of type 1 cysts in the concordant group compared to 37.7 % in the discordant group (P = 0.001), which suggests a different activity of the epithelium lining the cyst wall.<\/jats:p>","DOI":"10.1177\/030089169207800310","type":"journal-article","created":{"date-parts":[[2018,4,23]],"date-time":"2018-04-23T11:17:42Z","timestamp":1524482262000},"page":"198-199","source":"Crossref","is-referenced-by-count":0,"title":["Cationic Content in Multiple Mammary Cysts"],"prefix":"10.1177","volume":"78","author":[{"given":"Paola","family":"Ballerini","sequence":"first","affiliation":[{"name":"Unit\u00e0 di Endocrinologia, Divisione di Oncologia Medica \u00ab B \u00bb;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Callegari","sequence":"additional","affiliation":[{"name":"Divisione di Analisi Cliniche e Microbiologiche, Istituto Nazionale per lo Studio e la Cura dei Tumori, Milano"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivan","family":"Del Prato","sequence":"additional","affiliation":[{"name":"Divisione di Oncologia Chirurgica Diagnostica, Istituto Nazionale per lo Studio e la Cura dei Tumori, Milano"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniele","family":"Moglia","sequence":"additional","affiliation":[{"name":"Divisione di Oncologia Chirurgica Diagnostica, Istituto Nazionale per lo Studio e la Cura dei Tumori, Milano"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Annamaria","family":"Cerrotta","sequence":"additional","affiliation":[{"name":"Divisione di Oncologia Chirurgica Diagnostica, Istituto Nazionale per lo Studio e la Cura dei Tumori, Milano"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Adorni","sequence":"additional","affiliation":[{"name":"Unit\u00e0 di Endocrinologia, Divisione di Oncologia Medica \u00ab B \u00bb;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonardo","family":"Ferrari","sequence":"additional","affiliation":[{"name":"Unit\u00e0 di Endocrinologia, Divisione di Oncologia Medica \u00ab B \u00bb;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giorgio","family":"Secreto","sequence":"additional","affiliation":[{"name":"Unit\u00e0 di Endocrinologia, Divisione di Oncologia Medica \u00ab B \u00bb;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1992,6,1]]},"reference":[{"key":"bibr1-030089169207800310","doi-asserted-by":"publisher","DOI":"10.1016\/0277-5379(90)90222-F"},{"key":"bibr2-030089169207800310","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.1991.433"},{"key":"bibr3-030089169207800310","doi-asserted-by":"publisher","DOI":"10.1016\/0277-5379(85)90289-5"},{"key":"bibr4-030089169207800310","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800701012"},{"key":"bibr5-030089169207800310","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800720311"},{"key":"bibr6-030089169207800310","doi-asserted-by":"publisher","DOI":"10.1016\/0277-5379(86)90137-9"},{"key":"bibr7-030089169207800310","first-page":"227","volume":"9","author":"Miller W.R.","year":"1983","journal-title":"Clin.
