Abdominoplasty with two fusiform plications.

Two-fusiform plications are recommended for contouring the abdomen to produce a slimmer waistline in abdominoplasty, rather than the classical median xiphoid-pubic fusiform plication. This procedure was accomplished in 11 patients. After the dermoadipose flap was undermined, two fusiform shapes were marked at the transition of the sheaths of the rectus abdominis muscles with the external obliques. The slimmer waistline produced intraoperatively was maintained during the late postoperative period (mean 20 months), without loss of the natural contour between the rectus muscles. Maintenance of the natural contours of the abdominal muscles is of fundamental importance to reduce the embarrassment of a postabdominoplasty flat abdomen.

H-Shaped, double-contour plication in abdominoplasty.

H-shaped, double-contour plication, by reducing the longitudinal and transverse abdominal diameters, improves the waistline and reinforces the entire anterior abdominal wall, with better accommodation of the cutaneous flap. The decrease in the longitudinal diameter allows lowering and fixation of the cutaneous flap without tension.

Skeletal maturity and socio-economic status in Portuguese children and youths: the Madeira growth study.

BACKGROUND: Skeletal maturity is used to evaluate biological maturity status. Information about the association between socio-economic status (SES) and skeletal maturity is limited in Portugal. AIMS: The aim of this study is to document the skeletal maturity of youths in Madeira and to evaluate variation in maturity associated with SES. SUBJECTS AND METHODS: The study involved 507 subjects (256 boys and 251 girls) from the Madeira Growth Study, a mixed-longitudinal study of five cohorts (8, 10, 12, 14 and 16 years of age) followed at yearly intervals over 3 years (1996-1998). A total of 1493 observations were made. Skeletal age was estimated from radiographs of the hand and wrist using the Tanner-Whitehouse 2 method (TW2). Social class rankings were based on method. Five social rankings were subsequently grouped into three SES categories: high, average and low. RESULTS: Median for the radius, ulna and short finger bones (RUS scores) in the total sample of boys and girls increased curvilinearly across age whereas median for the 7 (without pisiform) carpal bones (Carpal scores) increased almost linearly. The 20-bone maturity scores demonstrated distinctive trends by gender: the medians for boys increased almost linearly while the medians for girls increased curvilinearly. SES differences were minimal. Only among children aged 10-11 years were high SES boys and girls advanced in skeletal maturity. Madeira adolescents were advanced in skeletal maturity compared with Belgian reference values. CONCLUSION: The data suggests population variation in TW2 estimates of skeletal maturation. Skeletal maturity was not related to SES in youths from Madeira.

Comparison of once- with twice-daily dosing of fluticasone propionate in mild and moderate asthma.

OBJECTIVES: Two 12-week, randomized, double-blind, parallel-group studies were performed to compare the efficacy and safety of once- and twice-daily dosing of fluticasone propionate (FP) in the treatment of mild to moderate asthma, considered to require the equivalent of either 200 or 500 microg of FP daily. PATIENTS AND METHODS: In study A, 461 patients with asthma received FP either 200 microg once daily or 100 microg twice daily. In study B, 443 patients with asthma received FP, either 500 microg once daily or 250 microg twice daily. RESULTS: In both studies, regardless of the treatment regimen to which patients were randomly assigned, small improvements over baseline were observed in morning peak expiratory flows (PEF) and forced expiratory volume in 1 s (FEV1) following 12 weeks of treatment. In study A, the mean morning PEF improved by 2.4% and 4.3% (once daily versus twice daily, P=0.008). In study B, the mean morning PEF improvement was 0.2% and 3.7% (once daily versus twice daily, P<0.001). For both studies, the increases observed in FEV1 were not significantly different between the two groups (P = not significant). The incidence of exacerbations of asthma and related events was 13% and 5%, respectively, in the patients with mild asthma for the once-daily group versus the twice-daily group; these exacerbations were 12% and 10%, respectively, in patients with moderate asthma. Otherwise, the incidence and types of adverse events were comparable for the two treatment regimens. Although twice-daily dosing demonstrated small but statistically significant improvements over once-daily dosing, patients of both groups generally maintained a good level of asthma control on both regimens according to current treatment guidelines. CONCLUSIONS: Twice-daily dosing of FP is more effective than once-daily dosing, although the latter can maintain asthma control in most patients.

[Crohn disease with unusual cutaneous expression].

Perianal fistula is a frequent complication of Crohn's disease. The diagnosis of the later may be difficult if cutaneous disease is dominant, and sometimes an important clinical challenge. The authors report a case of a 34 year old male complaining of painful perianal nodules for the three last years. Cutaneous histopathological examination was inespecific and colonoscopy normal. Pelvic CT scan and fistulography showed an intercommunicated fistular system invading both isquiorectal fossae, without intestinal communication. Repetition of colonoscopy showed normal mucosa, but in two of the biopsy samples noncaseous granulomas were found at the submucosa. The authors explain their main difficulties to reach the diagnosis of Crohn's disease and discuss the investigation and the evolution of the patient.

Acute fibrinous and organizing pneumonia.

The term Acute Fibrinous and Organizing Pneumonia (AFOP) has been proposed by Beasley et al for cases that do not fit into the histopathologic criteria of the recognized entities described as acute or subacute clinical presentations. The presence of intra-alveolar fibrin in the form of fibrin "balls" and organizing pneumonia with patchy distribution are the main histological features of this entity. We describe the case of a male patient with the diagnostic of AFOP made by surgical lung biopsy. He had a subacute presentation of symptoms consisting of productive cough, chest pain and fever. Bilateral infiltrates with patchy and diffuse distribution were the predominant features in his chest HRCT scan. The patient had a good clinical course after a treatment with prednisone and cyclophosphamide. Our hope in reporting this case study is to add some more data to the discussion of this new entity.

[Acute pancreatitis: inflammatory effusions--course and prognosis].

Ten to twenty per cent of Acute Pancreatitis (AP) attacks are severe and their evolution depends on regional or systemic complications and medical of surgical management applied. Three hundred and twelve cases of AP were retrospectively studied, 51 of which had pancreatic or peripancreatic effusions (early fluid effusion--14%; pseudocyst--14%; phlegmon--43% abscess--29%). Mortality in this group (33%) was greater than in the overall population (5.9%): Alcoholic etiology, concomitant systemic complications and early surgery were determinant factors. Prognostic criteria evaluated had a predictive value of about 80%. Fifty per cent of patients with phlegmon had spontaneous resolution after medical intensive care management. Diagnosis of secondary infection of pancreatic and peripancreatic necrosis is determinant for optimal surgical management. Mortality in abscess was 40%, greater when surgical drainage was done in the first two weeks of disease.

[Acute lithiasic pancreatitis. Usefulness of a multiple quantitative index].

The authors present a prospective study of early diagnosis of biliary etiology in Acute Pancreatitis, using a Multiple Quantitative Index. A positive diagnosis was achieved in more than a 80% of cases if female, age over or equal 55 years, and serum alanine-aminotransferase over or equal twice normal. Some questions concerning usefulness and therapeutical implications of an early diagnosis of Biliary Pancreatitis is already present in discussion.
