Background: Exsanguinating extremity wounds remain the primary source of battlefield mortality. Operating forces employ three agents in Iraq: HemCon® (HemCon Medical Technologies, Inc., Portland, OR), QuikClot® (Z-Medica Corporation, Wallingford, CT), and CELOX™ (SAM Medical, Tualatin, OR). Anecdotal reports suggest that these agents are less useful on small entrance, linear-tract injuries. ChitoFlex® (HemCon Medical Technologies, Inc., Portland, OR) has been introduced but is untested. Study Objectives: To compare the equivalency of the ChitoFlex® dressing, QuikClot® ACS+™ dressing, CELOX™, and standard gauze in their effectiveness to control bleeding from non-cavitary groin wounds. Methods: Forty-eight swine were randomly assigned to one of four treatment groups: standard gauze dressing (SD), ChitoFlex® dressing (CF), QuikClot® ACS+™ dressing (QC), and CELOX™ dressing (CX). A groin injury with limited vessel access was created in each animal. Subjects were resuscitated with 500 mL of hetastarch. The primary endpoint was 180-min survival. Secondary endpoints included total blood loss in mL/kg, incidence of re-bleeding, survival times among the animals that did not survive for 180 min, failure to achieve initial hemostasis, incidence of recurrent bleeding, time to initial re-bleeding, amount of re-bleeding, and mass of residual hematoma. Results: Survival occurred in 10 of 12 SD animals, 10 of 12 CF animals, 10 of 12 QC animals, and 9 of 12 CX animals. No statistically significant difference was found. Conclusion: In our study of limited-access extremity bleeding, ChitoFlex® performed equally well in mitigating blood loss and promoting survival. The ChitoFlex® dressing is an equally effective alternative to currently available hemostatic agents. However, no agents were superior to standard gauze in our model of limited access. 相似文献

ABSTRACT: Zinc is an essential trace element whose malabsorption in early childhood may result in a skin disorder known as acrodermatitis enteropathica. Cutaneous lesions typical of acrodermatitis enteropathica have been described during total parenteral nutrition on zinc-deficient intravenous solutions in both adults and children. This condition has been named the “acute zinc depletion syndrome.” A case is described in which a patient, despite a zinc intake of double the daily requirement, manifested the acute zinc depletion syndrome during therapy with combined liquid diet plus parenteral hyperalimentation. Predisposing factors in this individual included a short bowel syndrome and a large oral load of calcium lactate. Zinc metabolism is reviewed with attention to alterations in disease and during hyperalimentation. The clinical manifestations, predisposing factors, therapy and prevention of the acute zinc depletion syndrome are discussed. 相似文献

Background. In patients with HIV-1 disease there has been an increasing association with human papilloma virus (HPV) infections in multiple locations as well as an increase in associated tumors. In addition, there has been increased recovery of HPV in individuals with decreasing T4 cell counts. Case Report. Recently we have seen an HIV-I+ patient with a cutaneous lesion on the nipple, as well as multiple perianal lesions in which HPV-16 was demonstrated by in-situ hybridization. Although these lesions contained the same subtype of HPV virus, they had very different clinical and histopathologic morphologies, and this represents the first reported association of HPV-16 in a nipple lesion. Discussion. Our patient illustrates that in HIV-I disease, HPV infections may present in more diffuse and atypical locations. In addition, the diffuse staining with the in-situ probe for HIV-16 within the lesions, tends to support the findings of others, that viral recovery increases with the immune suppression induced by HIV-I. 相似文献

Squamous Cell Carcinoma in Situ (Bowen''s Disease) in Renal Transplant Patients Treated with 5% Imiquimod and 5% 5-Fluorouracil Therapy 总被引:2,自引:0,他引:2

BACKGROUND: Depending upon the patient's age at transplant, skin type, sun exposure, and the need for immunosuppressive therapy to prevent rejection, there is escalation in the development of cutaneous malignancies in organ transplant patients a number of years after transplantation. Thus, with the expansion in these procedures over the past decades, and the ever-lengthening survival of these patients, we are seeing an increase in cutaneous malignancies in this patient population. OBJECTIVE: To determine if combined therapy with 5% 5-fluorouracil and 5% imiquimod may be useful in the treatment of squamous cell carcinoma in situ. METHODS: We present five renal transplant patients, all more than 10 years posttransplantation, three with insulin-dependent diabetes, who developed multiple areas of squamous cell carcinoma (SCC) in situ. All these patients were on chronic immunosuppressive chemotherapy to prevent rejection, but were otherwise doing well. All the patients had biopsy-proven SCC in situ on their lower extremities that even in normal patients may be a challenge to treat. RESULTS: We treated these five patients with a combination of a local immune therapy, imiquimod cream, and a topical chemotherapeutic agent, 5% 5-fluorouracil (5-FU), with clearing of the areas of SCC in situ. CONCLUSION: Although immunotherapy must be used with caution in organ transplant patients to avoid graft rejection, topical imiquimod is a local immune modulator that potentiates local innate and possible adaptive immunity without measurable effects on systemic immunity. In addition, there is evidence that cytokines induced by imiquimod may improve the therapeutic efficacy of topical 5% 5-FU in the treatment of SCC in situ. 相似文献

Congenital coronary aneurysms with angina pectoris and myocardial infarction treated with saphenous vein bypass graft 总被引:2,自引:0,他引:2

A young woman with bilateral congenital coronary arterial aneurysms associated with myocardial infarction and angina pectoris was successfully treated with a saphenous vein bypass graft. Possible clinical and laboratory manifestations of such aneurysms are discussed, and possible complications of saphenous vein graft surgery in treatment of this lesion are noted. The finding of coronary arterial aneurysms during coronary arteriography warrants close follow-up study since in many patients the lesion appears to progress to myocardial infarction. 相似文献
