Granulocytic sarcoma: An atypical presentation in the oral cavity

Acute myelogenous leukemia (AMU is a hematologic disorder that is characterized by an abnormal proliferation of immature myeloid cells. Granulocytic sarcomas are clusters of leukemic myeloid cells that may develop as a result of AML. Oral manifestations of AML are common and often involve enlargements of the gingiva and/or mucosal tissue from direct leukemia cell infiltration. We describe the case history of a 50-year-old man who had an ulcera-tive lesion of the oral mucosa that was determined to be a granulocytic sarcoma of AML-M0 subtype. The combination of both the subtype and clinical presentation of the leukemia makes this presentation unusual, and to the best of our knowledge, of a type that has not been previously reported in the literature.     

Lung Transplant Metalloproteinase Levels Are Elevated Prior to Bronchiolitis Obliterans Syndrome

Parenchymal disease in the allograft lung is associated with interstitial remodeling believed to be mediated by matrix metalloproteinases (MMPs). Recent studies suggest high levels of MMP-9 are associated with bronchiolitis obliterans syndrome (BOS) in lung transplant recipients. Since BOS occurs late in the posttransplant period and may be preceded by episodes of acute rejection or infection, which are associated with interstitial remodeling, we examined MMP profiles in allograft bronchoalveolar lavage (BAL) fluid in the early posttransplant period (preceding BOS). Gelatin zymography, protein array analysis and specific ELISA on BAL fluids from transplanted lungs indicated that MMP-8, MMP-9 and TIMP-1 were strongly expressed in allograft BAL fluid from stable patients, or those with infection or rejection compared to BAL fluid from normal volunteers. Elevated expression of MMP-8, MMP-9 and TIMP-1 occurred early, and was sustained for the 3.2 years covered in this study. Elevations of MMP-8, MMP-9 and TIMP-1 in the first 2 years posttransplant appear to be associated with lung transplantation itself, and not infection or rejection. These data suggest that ongoing and clinically silent MMP activity could perpetuate progressive disease in the allograft lung.     

Reliability of reporting nosocomial infections in the discharge abstract and implications for receipt of revenues under prospective reimbursement.

Proper reporting of discharge diagnoses, including complications of medical care, is essential for maximum recovery of revenues under the prospective reimbursement system. To evaluate the effectiveness of abstracting techniques in identifying nosocomial infections at discharge, discharge abstracts of patients with nosocomial infections were reviewed during September through November of 1984. Patients with nosocomial infections were identified using modified Centers for Disease Control (CDC) definitions and trained surveillance technicians. Records which did not include the diagnosis of nosocomial infections in the discharge abstract were identified, and potential lost revenues were estimated. We identified 631 infections in 498 patients. On average, only 57 per cent of the infections were properly recorded and coded in the discharge abstract. Of the additional monies which might be anticipated by the health care institution to assist in the cost of care of adverse events, approximately one-third would have been lost due to errors in coding in the discharge abstract. Although these lost revenues are substantial, they constitute but a small proportion of the potential costs to the institution when patients acquire nosocomial infections.     

Repair of the Alar Groove with Combination Partial Primary Closure and Second-Intention Healing

BACKGROUND: The reconstruction of small defects of the alar groove can be a unique challenge owing to the importance of maintaining its concave structure. OBJECTIVE: To present a report of a patient with a small alar groove defect that was repaired using a combination of partial primary closure and second-intention healing. METHODS: A 73-year-old female was referred for the treatment of a basal cell carcinoma of the right nasal ala and underwent Mohs micrographic surgery with clearance of the lesion. The final defect, less than 1 cm, extended to the subcutaneous fat. Two absorbable subcutaneous sutures were placed in the defect, and the wound was then allowed to heal by second intention. RESULTS. This closure yielded a good cosmetic result, with preservation of the alar groove. CONCLUSION: A combination of primary closure and second-intention healing is a time-efficient, low-risk option for nonperforating, small alar groove defects.
