RESUMO

OBJECTIVE: This study seeks to demonstrate the safety of anastomosing free flaps to the common or proper digital artery, and to the volar or dorsal digital vein in soft tissue reconstruction of the hand; as well, as to discuss the advantages of this technique. METHODS: Retrospective review of all patients who underwent free flap reconstruction of the hand in two institutions over a period of 5 years. RESULTS: A total of 29 free flaps (9 great toe pulp, 7 anterolateral thigh, 6 second toe pulp, 4 radial artery perforator, 2 partial medial rectus, 1 lateral arm) in 28 patients met our inclusion criteria. All recipient vessels were the proper or common digital artery and the volar or dorsal digital vein. There was one case of venous congestion that resolved with leeching. There was no partial or total loss of any of the flaps. CONCLUSION: Anastomosing soft tissue free flaps to the common or proper digital artery, and the volar or dorsal digital vein is a safe and effective approach with numerous advantages that should be considered in the reconstruction of soft tissue defects of the hand. © 2016 Wiley Periodicals, Inc.

RESUMO

A subgroup of patients with 22q11.2 microdeletion and partial DiGeorge syndrome (pDGS) appears to be susceptible to non-cardiac mortality (NCM) despite sufficient overall CD4(+) T cells. To detect these patients, 20 newborns with 22q11.2 microdeletion and congenital heart disease were followed prospectively for 6 years. Besides detailed clinical assessment, longitudinal monitoring of naive CD4(+) and cytotoxic CD3(+)CD8(+) T cells (CTL) was performed. To monitor thymic activity, we analysed naive platelet endothelial cell adhesion molecule-1 (CD31(+)) expressing CD45RA(+)RO(-)CD4(+) cells containing high numbers of T cell receptor excision circle (T(REC))-bearing lymphocytes and compared them with normal values of healthy children (n = 75). Comparing two age periods, low overall CD4(+) and naive CD4(+) T cell numbers were observed in 65%/75%, respectively, of patients in period A (< 1 year) declining to 22%/50%, respectively, of patients in period B (> 1/< 7 years). The percentage of patients with low CTLs (< P10) remained robust until school age (period A: 60%; period B: 50%). Low numbers of CTLs were associated with abnormally low naive CD45RA(+)RO(-)CD4(+) T cells. A high-risk (HR) group (n = 11) and a standard-risk (SR) (n = 9) group were identified. HR patients were characterized by low numbers of both naive CD4(+) and CTLs and were prone to lethal infectious and lymphoproliferative complications (NCM: four of 11; cardiac mortality: one of 11) while SR patients were not (NCM: none of nine; cardiac mortality: two of nine). Naive CD31(+)CD45RA(+)RO(-)CD4(+), naive CD45RA(+)RO(-)CD4(+) T cells as well as T(RECs)/10(6) mononuclear cells were abnormally low in HR and normal in SR patients. Longitudinal monitoring of naive CD4(+) and cytotoxic T cells may help to discriminate pDGS patients at increased risk for NCM.

RESUMO

BACKGROUND: This study aimed to evaluate the cardiac outcome for children with microdeletion 22q11.2 and congenital heart defect (CHD). METHODS: A total of 49 consecutive children with 22q11.2 and CHD were retrospectively identified. The CHD consisted of tetralogy of Fallot and variances (n = 22), interrupted aortic arch (n = 10), ventricular septal defect (n = 8), truncus arteriosus (n = 6), and double aortic arch (n = 1). Extracardiac anomalies were present in 46 of 47 children. RESULTS: The median follow-up time was 8.5 years (range, 3 months to 23.5 years). Cardiac surgical repair was performed for 35 children, whereas 5 had palliative surgery, and 9 never underwent cardiac surgery. The median age at repair was 7.5 months (range, 2 days to 5 years). The mean hospital stay was 35 days (range, 7-204 days), and the intensive care unit stay was 15 days (range, 3-194 days). Significant postoperative complications occurred for 26 children (74%), and surgery for extracardiac malformations was required for 21 patients (43%). The overall mortality rate was 22% (11/49), with 1-year survival for 86% and 5-year survival for 80% of the patients. A total of 27 cardiac reinterventions were performed for 16 patients (46%) including 15 reoperations and 12 interventional catheterizations. Residual cardiac findings were present in 25 patients (71%) at the end of the follow-up period. CONCLUSIONS: Children with microdeletion 22q11.2 and CHD are at high risk for mortality and morbidity, as determined by both the severity of the cardiac lesions and the extracardiac anomalies associated with the microdeletion.

RESUMO

AIM: To study features in older patients with autoimmune hepatitis, as this was considered mainly a disease of young females. METHODS: Analysis of 28 patients diagnosed at age > or =65 years compared with 84 younger patients. RESULTS: The incidence was similar at all age decades. The ratio M:F was 1:3 (> or =65 years) vs. 1:2 (<65 years). Presenting symptoms were not different when compared with younger patients and consisted of general malaise and fatigue (36%), jaundice +/- other symptoms (50%), or ascites (11%). Antinuclear antibodies (ANA) > or = 1/80 were positive in 93%, smooth muscle antibodies (SMA) > 1/40 in 50%, anti-liver kidney microsomes (anti-LKM) proved always negative. Histology showed acute necrotizing hepatitis in 19%, severe interphase hepatitis in 15%, chronic hepatitis with plasmo-lymphocytic infiltrate in 30%, cirrhosis in 29% (with active inflammation in one-third); biopsy was refused in 11%. The elderly responded very well to low doses of methylprednisolone (< or =8 mg) and azathioprine (1 mg/kg). This schedule obviates side-effects such as infections seen with higher dosages. CONCLUSION: Autoimmune hepatitis has to be also looked for in the elderly with acute and chronic hepatitis. The steroid therapy should be individualized but kept at a low dose.

RESUMO

The desire to maintain or regain a youthful appearance is the main motivation of patients who present themselves to the aesthetic plastic surgeon's office. It has become imperative for the plastic surgeon to know and understand the causes of aging and skin damage and to provide ancillary nonsurgical treatments through which their patients can achieve rejuvenation.
