Her representative matters include:
- Represented a geriatrician in a three-and-a-half week wrongful death trial of a 36 year old woman. Plaintiff alleged the defendant physician failed to appropriately manage the 34 year old plaintiff's condition, failed to write the appropriate orders and failed to bring in the appropriate specialists which led to an overall decline in the patient's condition including weight loss, development and exacerbation of decubitus ulcers in excess of 15 before her death, osteomyelitis, sepsis and death at the age of 36. Plaintiff further alleged that the plaintiff was being physically and sexually abused while a resident in the nursing home and that the defendant was aware of the abuse having secretly ordered a pregnancy test after the resident who was unable to communicate, walk or provide consent to sex, developed repeated urinary tract infections and a herpetic outbreak on her genitals while under the defendant's care. The defendant also testified in a deposition he suspected someone was hitting her yet allegedly failed to document or report the abuse while she was a resident in the home. The defense argued that the defendant appropriately managed her condition, that it was the nursing home's responsibility to carry out his orders and provide daily care and that the weight loss and decubitus ulcers were instead caused by the resident's progressive and fatal neurodegenerative disease. The defense also argued that the defendant was neither physically nor sexually abused. Instead, the patient's bruises were a result of documented falls in the home in a resident who was on blood thinners which are known to cause bruising. Furthermore, the defense argued that the resident had known preexisting herpes and the pregnancy test was ordered as routine for women of child-bearing age. Plaintiff asked for $6.25 million and the jury returned a not guilty verdict.
Represented a gastroenterologist and his group in a three-and-a-half week wrongful death trial of a 64 year old woman. Plaintiff alleged defendants misdiagnosed the patient with gall bladder disease. They alleged defendants further failed to timely diagnose and treat a paraesophageal hernia by failing to order a CT scan after the patient presented to the emergency department with persistent abdominal pain and subsequent testing had ruled out the gall bladder as the etiology of her pain. Plaintiff contended a CT scan would have timely made the diagnosis and would have avoided subsequent strangulation, rupture, cardiac arrest and death. The defense argued plaintiff presented with the classic signs of a gall bladder attack which later showed signs of improvement allowing the defense to wait to order further testing. When the patient’s condition deteriorated the following day, appropriate testing had been ordered, an EGD, which would have diagnosed a hernia, but the plaintiff refused to undergo the testing allegedly due to excruciating pain. Shortly thereafter, the patient arrested, coded, and was taken to emergency surgery, dying four days later. Plaintiff asked for $3.65 million, and the jury returned a not guilty verdict the same day.
- Represented an oncologist in a medical malpractice suit in which plaintiff, a 44 year old woman, presented to our client with stage 3 breast cancer and was treated with Adriamycin chemotherapy which has a known risk of cardiotoxicty or heart damage. Plaintiff alleged a failure to diagnose a subclinical or underlying cardiomyopathy as well as a failure to order an echocardiogram, MUGA scan, and cardiology consult after the patient later developed signs and symptoms of cardio toxicity which led to permanent heart failure and the need for a heart transplant. Plaintiff also alleged a decreased life expectancy, with approx 10 years of life remaining. After a two week trial, plaintiff's counsel asked the Cook County jury for $21 million, and the jury returned the same day with a verdict of not guilty as to all counts.
- Represented a Chicagoland hospital in an obstetrical negligence action involving an alleged failure to timely perform a Cesarean section resulting in fetal brain damage and cerebral palsy. Plaintiff specifically alleged that the fetus sustained brain damage during the second stage of labor due to venous sinus stagnation thrombosis (VSST). VSST is a condition that allegedly occurs from excessive pressure placed on the fetus' head while in the occiput posterior position during a prolonged second stage of labor, and with an arrest of descent. The plaintiff, now 15 years old, suffers spastic triplegia and is wheelchair-bound. After two weeks of trial, plaintiff asked in excess of $19 million and the jury returned a not guilty verdict in favor of the hospital.
- Represented an internist in a medical malpractice action involving an alleged failure to timely diagnose and treat a spinal hematoma in a 61-year-old female after undergoing a femoral popliteal bypass graft surgery rendering her paraplegic. Plaintiff specifically alleged that the internist was negligent in relying on medical advice given by a neurosurgeon over the telephone, rather than transferring the patient to a hospital where a neurosurgeon could perform an in-person consultation which would have necessitated immediate neurosurgery to evacuate the hematoma. Due to the multiple defendants' alleged negligence, the patient became paraplegic, wheelchair-bound, and subsequently had both legs amputated. The patient also suffered bilateral pulmonary emboli and required placement of a permanent suprapubic catheter. After 3.5 weeks of trial, plaintiff asked for more than $21 million and the jury returned a not guilty verdict in favor of defendants.
- Tried a wrongful death medical malpractice case in Cook County, Illinois. Defendant nephrologist had been managing a patient on anticoagulant medication as an inpatient at a hospital. On the day of discharge, the patient went into a violent seizure and was diagnosed with a massive subarachnoid hemorrhage. Plaintiffs argued that the nephrologist was negligent because he had been contacted the evening before by a nurse, advising him that the patient was complaining of a severe headache despite having been given morphine and several vicodin pills. Plaintiffs argued that this fact, along with the fact that the patient’s anticoagulation levels were over the therapeutic limits, meant that the standard of care required an emergency CT scan and neurology consult to rule out the beginnings of a subarachnoid bleed as the cause of this headache. Plaintiffs asked the jury for $7.7 million. The jury returned a verdict of not guilty.
- Successfully defended a $1.25 million claim against a local physician for failure to properly perform surgery where the jury returned a not guilty verdict on behalf of the physician.
- Successfully defended a $25 million claim against a local hospital, alleging obstetrical negligence. Case was settled on behalf of the hospital.
