Fibrolipoma of Flexor Digitorum Profundus Tendon of Ring Finger Causing Triggering and Intermittent Carpal Tunnel Syndrome.

Introduction: Lipomas are most common soft-tissue tumors but rarely are found to be symptomatic. <1% of lipomas are found in hand. Subfascial lipomas can cause pressure symptoms. Carpal tunnel syndrome (CTS) can be idiopathic or secondary to any space-occupying lesion. Triggering usually occurs due to inflammation/thickening of A1 pulley. Most have reported a lipoma in distal forearm or near median nerve, leading to triggering of index or middle finger and carpal tunnel symptoms. All the cases reported had either an intramuscular lipoma in flexor digitorum superficialis (FDS) tendon slip of index or middle finger, with or without accessory belly of FDS muscle or a neurofibrolipoma of the median nerve. In our case, the lipoma was under palmer fascia, in flexor digitorum profundus (FDP) tendon sheath of fourth finger causing triggering of the ring finger and CTS symptoms in flexion of the ring finger. Hence, this is a first report of this kind in the literature. Case Report: We hereby report a one of its kind case in which a 40-year-old Asian male patient had triggering of the ring finger with associated intermittent CTS symptoms, on making a fist, secondary to space-occupying lesion in palm, which was diagnosed by ultrasound as lipoma in FDP tendon of the ring finger in palm. This lipoma was surgically removed by AO ulnar palmer approach and carpal tunnel was decompressed. Histopathology report confirmed the lump to be fibrolipoma. The patient had complete relief of symptoms postoperatively. At 2 years follow-up, there was no recurrence.

Errors of Commission in Cardiac Arrest Care in the Intensive Care Unit.

INTRODUCTION: Cardiopulmonary arrests (CPAs) are common in the intensive care unit (ICU). However, effects of protocol deviations on CPA outcomes in the ICU are relatively unknown. OBJECTIVES: To establish the frequency of errors of commission (EOCs) during CPAs in the ICU and their relationship with CPA outcomes. METHODS: Retrospective analysis of data entered into institutional registry with inclusion criteria of age >18 years and non-traumatic cardiac arrest in the ICU. EOCs consist of administration of drugs or procedures performed during a CPA that are not recommended by ACLS guidelines.Primary outcome: relationship of EOCs with likelihood of return of spontaneous circulation (ROSC). Secondary outcomes: relationship of specific EOCs to ROSC and relationship of EOCs and CPA length on ROSC. RESULTS: Among 120 CPAs studied, there was a cumulative ROSC rate of 66%. Cumulatively, EOCs were associated with a decreased likelihood of ROSC (OR: 0.534, 95% CI: 0.387-0.644). Specifically, administration of sodium bicarbonate (OR: 0.233, 95% CI: 0.084-0.644) and calcium chloride (OR: 0.278, 95% CI: 0.098-0.790) were the EOCs that significantly reduced likelihood of attaining ROSC. Each 5-minute increment in CPA duration and/or increase in number of EOCs corresponded to fewer patients sustaining ROSC. CONCLUSIONS: EOCs during CPAs in the ICU were common. Among all EOCs studied, sodium bicarbonate and calcium chloride seemed to have the greatest association with decreased likelihood of attaining ROSC. Number of EOCs and CPA duration both seemed to have an inversely proportional relationship with the likelihood of attaining and sustaining ROSC. EOCs represent potentially modifiable human factors during a CPA through resources such as life safety nurses.
