Critical Homecare Solutions Inc., a Conshohocken, Penn.-based provider of home infusion therapy services to patients suffering from acute or chronic conditions, has withdrawn registration for a $125 million IPO. The move comes shortly after Critical Homecare owner Kohlberg & Co. agreed to sell the company to MBF Healthcare Acquisition Corp. (AMEX: MBH) for approximately $420 million. That sale has not yet closed. www.kohlberg.com/chs.html
