Objectives/Hypothesis: To determine factors impacting recurrence and long-term survival of adenoid cystic carcinoma (ACC) of the head and neck after definitive resection.Study Design: Retrospective cohort study at an academic tertiary care hospital.Methods: Patients with ACC of the head and neck treated at our institution were reviewed. Those not receiving surgery, or with metastatic disease were excluded. Clinicopathological data on each patient was collected.Results: Of 113 patients identified with ACC, 99 were studied. The overall median survival for the cohort was 71 months (mean AE standard deviation, 94 AE 79 months). American Joint Committee on Cancer (AJCC) tumor stage and N stage were independent predictors of survival on multivariate analysis. Mean overall survival (P ¼ .001) and time to recurrence (P ¼ .006) were lower for patients with cervical lymph node positive disease (Nþ). Tumors in major salivary glands were associated with longer survival (P ¼ .027). The overall recurrence rate was 53%, with a mean time to recurrence of 63 AE 64 months. The presence of lymphovascular invasion predicted recurrence on multivariate analysis (P ¼ .002), with advanced tumor stage predicting early ( 36 months) recurrence (P ¼ .013). Among the 57 patients who received adjuvant radiation therapy, there was no difference in survival, rate of recurrence, or time to recurrence, when compared to patients treated with surgery alone.Conclusions: Clinicopathological variables including AJCC tumor stage, tumor site, presence of Nþ disease, and lymphovascular invasion may be used as prognostic factors in predicting survival and recurrence after a definitive resection of ACC of the head and neck.
Patient outcomes concerning toxic epidermal necrolysis (TEN) have improved over the years as a better understanding of the pathophysiology of the illness has been gained and enhancements have been made in the care of the acutely ill. With increase in survival, long-term complications these patients experience are beginning to be recognized. In this study, we analyzed the outcomes of a cohort of TEN survivors treated at our burn unit and sought to determine the impact of clinical variables from the initial hospitalization on mortality after discharge. We performed a retrospective review of data from patients with TEN treated at our burn unit from March 1993 to September 2002. Follow-up data on new health problems were collected on patients who were alive at discharge via questionnaire. Survival was estimated using the Kaplan-Meier method with Cox regression model. During the study period, of the 64 patients treated for TEN, 46 survived. After discharge, 15 patients died, whereas the remaining 31 patients continued to suffer from ocular (54%), skin (81%), and renal (23%) problems. Median survival for the whole cohort has not been reached, with an estimated 5-year survival of 65%. No patient in either group had a TEN recurrence. Seventy-nine percent of the patients with ocular involvement in the acute phase of TEN had long-term ocular complications, and 73% of patients with mucosal involvement had persistent mucosal lesions. Five individual factors were found to be predictors of postdischarge mortality on univariate analysis: age at diagnosis of TEN>or=60 years, SCORTEN 3 to 6, % maximal TBSA slough>or=50%, days from onset of symptoms to admission to a burn unit>or=5 days, and presence of multiple comorbidities at diagnosis of TEN. In multivariate analysis, only SCORTEN of 3 to 6 (P=.003) and days to admission>or=5 (P=.027) maintained significance as predictors of mortality and may be used to heighten surveillance during postdischarge care of patients with TEN.
Objective To investigate the effects of nasal continuous positive airway pressure (CPAP) and cannula use in the neonatal intensive care unit. Design Cross-sectional study. Setting Tertiary care children’s hospital. Patients One hundred patients (200 nasal cavities), younger than 1 year, who received at least 7 days of nasal CPAP (n = 91) or cannula supplementation (n = 9) in the neonatal intensive care unit. Interventions External nasal examination and anterior nasal endoscopy with photographic documentation. Main Outcome Measures The incidence and characteristics of internal and external nasal findings of patients with nasal CPAP or cannula use. Results Nasal complications were seen in 12 of the 91 patients (13.2%) with at least 7 days of nasal CPAP exposure, while no complications were seen in the 9 patients with nasal cannula use alone. The external nasal finding of columellar necrosis, seen in 5 patients (5.5%), occurred as early as 10 days after nasal CPAP use. Incidence of intranasal findings attributed to CPAP use, in the 182 nostrils examined, included ulceration in 6 nasal cavities (3.3%), granulation in 3 nasal cavities (1.6%), and vestibular stenosis in 4 nasal cavities (2.2%). Intranasal complications were seen as early as 8 to 9 days after nasal CPAP administration. Nasal complications from CPAP were associated with lower Apgar scores at 1 (P = .02) and 5 (P = .06) minutes. Conclusions External or internal complications of nasal CPAP can be relatively frequent (13.2%) and can occur early, and patients with lower Apgar scores may be at higher risk. Close surveillance for potential complications should be considered during nasal CPAP use.
