Pterygium axillae as a rare manifestation of Poland syndrome
2016
Abstract Poland syndrome is characterized by a combination of absent pectoralis muscle, abnormalities of the rib cage, the breast, as well as brachy-syndactyly. We report a case of a 3 month old girl who was born with right sided axillary pterygium combined with flattening of the right anterior chest wall. Resection of a sclerotic band with reconstruction by Z-plasty was performed. Intraoperative and histopathological findings confirmed that the axillary pterygium developed on the basis of a scarred, hypoplastic pectoralis major muscle. Our case adds to the body of evidence that Poland syndrome may present in a heterogeneous fashion, including the rare finding of axillary pterygium with ass…
Die α-Glycerophosphat-Oxydation des Heuschreckenbrustmuskels (Locusta migratoria)
1956
The conditions were studied for the glycerophosphate oxidation by homogenate from locust flight muscle, and the O2-consumption was measured. Maximal oxidation rates were found with 0.087m glycerophosphate, 8 × 10−6m cytochromec, 7 × 10−6m DPN and pH 7.5. The production of dihydroxyacetone phosphate is followed by further oxidation steps, as could be shown by estimation of the different fractions of acid-soluble phosphate. Comparative studies were made on different insects and vertebrates. The rate of succinate oxidation by insect muscle was found to be ten times higher than that of vertebrate muscle. The relation of glycerophosphate oxidation to succinate oxidation is quite different in ins…
Gynecomastia
2020
Gynecomastia is a swelling of the male breast as a result of the growth of two components: The adipose and the glandular tissue, sometimes unilateral, but more often occurring in bilateral form. Several classification systems were proposed, based on the hypertrophy of the tissue and the position of the nipple-areola complex. The clinical examination and blood analysis play an important role in excluding endocrine tumors or hormone balance modification and in choosing the treatment. The management of gynecomastia considers the drug therapy in case of hormones disorder. But surgical procedures, such as the combined adenectomy/liposuction, represent the gold standard of treatment. Skin redunda…
Machaeracanthus goujetin. sp. (Acanthodii) from the Lower Devonian of Spain and northwest France, with special reference to spine histology
2012
ABSTRACT We describe here a new machaeracanthid acanthodian (Machaeracanthus goujeti n. sp.), based on isolated spines, scales and scapulocoracoids from the Lower Devonian (Lochkovian-Pragian) of the Nogueras Formation, Celtiberia, Spain. The new taxon also includes a fragmentary spine and isolated scales from the Lower Devonian of northern Spain (Palencia and Cantabrian Mountains) and western France (Saint-Cenere) originally assigned to Machaeracanthus sp. The spines of M. goujeti n. sp. comprise two morphotypes in agreement with the morphofunctional model of a pair of pectoral spines articulating with the pectoral girdle already indicated for M. hunsrueckianum Sudkamp & Burrow, 2007, M. l…
Reconstruction of a Posterior Tracheal Wall Defect With a Myocutaneous Pectoralis Major Flap After Salvage Cervical Exenteration for a Squamous Carci…
2018
In this article, we describe the case of a 59-year-old patient suffering from a squamous cell carcinoma affecting the upper third of the esophagus, treated with a cervical exenteration with extended resection of the posterior wall of the trachea, which was reconstructed with a gastric tube transposition and a myocutaneous pectoralis major flap for coverage of the gastropharyngeal anastomosis and stabilization of the posterior tracheal wall. Also, a review of literature regarding posterior tracheal wall reconstruction is performed.
Poland’s Syndrome
2020
Poland’s syndrome is a sporadic, congenital thoracic deformity, mostly unilateral, with a wide spectrum of presentation. The thoracic malformations are distinguished on the basis of the anatomical site in which an embryological development alteration has occurred after the fourth week of gestation (Table 3.1) [1]. Poland’s syndrome is a rare congenital and complex anomaly of the development of thoracic muscles, characterized by hypoplasia of the breast and nipple, scarcity of subcutaneous tissue, absence of the costosternal portion of the pectoralis major muscle, lack of the pectoralis minor muscle, aplasia or deformity of the costal cartilages or ribs II to IV or III to V, alopecia of the …
