Febrile Ulceronecrotic Mucha-habermann Disease: a Rare, Severe Variant

JOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2006
Michele M. Thompson
A 56 year old Hispanic man presented with extensive ulcerative skin lesions, involving his lower trunk, groin and upper legs, severe pain and a temperature of 38.7 degrees Celsius. He was admitted to the Medical Intensive Care Unit for empiric intravenous antibiotics. Several biopsies were performed. In the following days his condition worsened and ulcerative lesions involved nearly all of his skin. Previous biopsies were consistent with pityriasis lichenoides et varioliformis acuta (PLEVA), however, neither this, nor others in the histological differential diagnosis, fit his severe and worsening clinical picture. Histology revealed vacuolar alteration with dyskeratotic keratinocytes and a superficial perivascular mixed infiltrate of lymphocytes and eosinophils. There was confluent parakeratosis containing neutrophils, and a diminished granular layer with pallor in the upper portion of the spinous layer. Immunofluorescence studies were negative. These findings were consistent with PLEVA. A clinical diagnosis of febrile ulceronecrotic Mucha-Habermann disease was made. Febrile ulceronecrotic Mucha-Habermann disease is a rare and severe variant of PLEVA characterised by high fever and papulonecrotic skin lesions. Twenty-five cases have been previously reported. We present the clinical and histological findings in this unusual clinical presentation. [source]


Effect of time of admission on compliance with deep vein thrombosis prophylaxis in a tertiary medical intensive care unit

JOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 6 2009
O. DABBAGH
Summary.,Objective:,We sought to evaluate deep vein thrombosis (DVT) prophylaxis compliance according to time of admission in a medical intensive care unit (MICU). Methods:,This was a retrospective cohort study at a closed tertiary MICU. We classified patients into three groups (week days, weekends, and week nights), according to time of admission. An unweighted risk factor score (RFS) was calculated from 20 known risk factors. We defined DVT prophylaxis compliance as any type of prophylaxis (mechanical or pharmacologic) for RFS , 3 or both types of prophylaxis for RFS > 3. Non-compliance was defined as no prophylaxis or single-type prophylaxis for RFS > 3. Results:,We analyzed 105 admissions. Eighty (76.19%) patients received compliant DVT prophylaxis, and 25 (23.81%) patients received non-compliant regimens of whom 11 (10.48%) were not on any prophylaxis. DVT prophylaxis compliance was not different across the three admission groups. The non-compliant DVT prophylaxis group had a higher RFS (3.48 ± 2.1 vs. 2.25 ± 1.5; P = 0.011), a trend towards fewer female patients (40% vs. 60%; P = 0.079), and a higher percentage of admissions by interns at the first postgraduate year (PGY) level (28% vs. 5.4%; P = 0.01). Logistic regression revealed that only RFS and PGY level were independent predictors for compliance (P = 0.015 and 0.005 respectively). Time of admission was not a significant factor. Conclusions:,Time of admission did not influence DVT prophylaxis compliance. Compliance improved with higher PGY level and lower RFS. A higher level of knowledge probably explains the association with PGY level; however, we cannot explain the inverse relationship between RFS and compliance. [source]


Identification and characterization of errors and incidents in a medical intensive care unit

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 7 2005
J. Graf
Background:, To assess the frequency, type, consequences, and associations of errors and incidents in a medical intensive care unit (ICU). Methods:, Two-hundred and sixteen consecutive patients with predominantly cardiovascular and pulmonary disorders admitted between December 2002 and February 2003 were enrolled. Demographic data, SAPS II, and TISS-28 were obtained for all patients. Prior to patient enrolment all staff members (physicians, nurses, physiotherapists) were repeatedly encouraged to make use of the Incident Report Form (IRF) and detailed descriptions on how, why and when to use the IRF were provided. Results:, During the observation period of 64 days, 50 errors involving 32 patients (15%) were reported. Patients subjected to errors were more severely ill (SAPS II 42 ± 25 vs. 32 ± 18, P < 0.05), had a higher hospital mortality (38% vs. 9%), and a longer ICU stay (11 ± 18 vs. 3 ± 5 days, P < 0.05). Gender, age and TISS-28 were equally distributed. Each day of ICU stay increased the risk by 8% (odds ratio 1.078, 95% confidence interval 1.034,1.125, P < 0.001), and by 2.3% per SAPS II point (odds ratio 1.023, 95% confidence interval 1.006,1.040, P < 0.001). The majority of errors and incidents were judged as ,human failures' (73%), and 46 errors and incidents (92%) as ,avoidable'. Conclusions:, The identification and characterization of errors and incidents combined with contextual information is feasible and may provide sufficient background information for areas of quality improvement. Areas with a high frequency of errors and incidents need to undergo process evaluation to avoid future occurrence. [source]


Adverse drug reactions in medical intensive care unit of a tertiary care hospital,

PHARMACOEPIDEMIOLOGY AND DRUG SAFETY, Issue 7 2009
Lisha Joshua MBBS
Abstract Purpose Patients in the intensive care unit (ICU) have multiorgan dysfunction as well as altered pharmacokinetic parameters. Hence they are susceptible to adverse drug reactions (ADRs). The objective of the study is to assess the characteristics of ADRs among inpatients in the medical ICU and to compare the same with patients who have not experienced ADRs. Methods Prospective, observational study for a period of 1 year in medical ICU of a tertiary care hospital. Relevant data of patients with ADRS were analysed. Characteristics of patients with and without ADRs were compared. Results Of 728 patients admitted in medical ICU, 222 (28.4%) had ADRs. Multiple ADRs (38.7%) implicated by the same drug and serious ADRs (37%) were noticed. Renal/electrolyte system (21%) was most commonly involved. Clinical spectrum included acute renal failure (ARF, 11.4%), hepatic injuries (5.4%), haematological dysfunction (4.2%), seizures (3.3%), upper gastrointestinal bleed (3.3%) and cutaneous ADRs (3.3%). Antimicrobials (27%) were the commonly implicated drug class. The most commonly implicated drug was furosemide (6.8%). Infrequently reported ADRs included azithromycin-induced erythema multiforme, leflunamide-induced erythema multiforme and vasculitis, ceftazidime-induced seizures and ceftriaxone-induced hepatitis. Co-morbidity, polypharmacy and duration of stay were significantly higher in patients with ADRs compared to those who have not experienced ADRs. Three patients died. Conclusion High incidence of serious and multiple ADRs noticed. A wide clinical spectrum of ADRs and infrequently reported ADRs to newer drugs were also observed.
