A 38-day-old male infant with persistent pulmonary hypertension and respiratory failure since birth was found to have a complete absence of surfactant protein B (SP-B) along with an aberrant form of SP-C in his tracheal aspirate fluid, findings consistent with the diagnosis of hereditary SP-B deficiency. Surprisingly, SP-B and SP-B messenger ribonucleic acid were present in lung biopsy tissue. However, DNA sequence analysis demonstrated a point mutation in exon 5 of one of the SP-B gene alleles. The infant's mother was found to be a carrier of this mutation. The infant's other SP-B allele did not differ from the published DNA sequence for the SP-B gene. We conclude that this patient had a transient deficiency of SP-B, in contrast to that of previously described infants with irreversible respiratory failure caused by hereditary SP-B deficiency. We recommend that infants with suspected SP-B deficiency have serial analysis of tracheal fluid samples for both SP-B and SP-C before lung biopsy, along with genetic analysis for the known SP-B mutations. We speculate that the new mutation found in one of this patient's SP-B genes was in part responsible for the transient deficiency of SP-B.
OBJECTIVE: To evaluate the rate of hematoma and seroma formation in a series of rhytidectomies performed with and without the use of intrawound vacuum drains. DESIGN: Retrospective chart review of 222 consecutive face-lifts performed by a single surgeon using an identical surgical technique before and after the use of vacuum wound drains. The patients were divided into 2 groups of 111 patients each. Group 1 patients underwent surgery without drains, while group 2 patients had suction drains placed at the time of surgery. MAIN OUTCOME MEASURE: The occurrence of seromas and hematomas within the first 24 hours after surgery. RESULTS: In group 1, 41 patients (37%) developed seromas and 9 (8%) developed hematomas; the hematomas were small and were treated by aspiration alone. In group 2, 17 patients (15%) developed seromas and 8 (7%) developed hematomas. The decrease in the rate of seroma occurrence was statistically significant, while the decrease in hematoma formation did not reach statistical significance. CONCLUSIONS: The use of intrawound vacuum drains during the first 24 hours after surgery significantly decreases the rate of seroma formation. The occurrence of hematomas is also reduced, but less dramatically.
PURPOSE: This prospective study was designed to assess the association of clear paranasal sinuses (no free fluid) as shown by facial computed tomography (CT) with the absence of fractures involving the paranasal sinus walls. PATIENTS AND METHODS: All facial CT scans performed during a 12-month period to rule out maxillofacial injury in blunt trauma patients were reviewed. The scans were made using 5-mm slice thickness and 4-mm table incrementation. They were assessed for the presence or absence of free paranasal sinus fluid (hemorrhage) and the presence and location of facial fractures. RESULTS: A total of 366 CT scans of the face were performed during the study. Among them, 180 scans (49%) were identified that showed no evidence of free paranasal fluid. Twenty-two (12%) of these 180 CT studies showed isolated nasal fractures (n = 13) or zygomatic arch fractures (n = 9). No patient without free paranasal sinus fluid had any midfacial fracture involving a paranasal sinus wall (P < .001 by Fischer exact test). CONCLUSION: The absence of free paranasal sinus fluid after facial trauma is a highly reliable criterion to exclude fractures involving the paranasal sinus walls. Other fractures involving osseous structures not contiguous with the paranasal sinus walls, such as nasal or zygomatic arch fractures, are not excluded. The CT "clear sinus" sign is a simple, rapid method to exclude paranasal sinus fractures.
