Introduction and Objectives The literature reports many variations of Poland syndrome, which is a congenital disorder and a rare condition. The associated features are extremely variable, including alterations in the ipsilateral thorax and upper extremity and other malformations. This is used to designate the condition as Poland sequence (PS) because a sequence is a primary defect with a secondary cascade of structural changes. It is generally accepted that it is characterized as pathognomonic by absence/aplasia of the sternocostal aspect of the pectoralis major muscle of one side. Because it is considered a rare disease, and the incidence is low, we aimed to determine the features in all patients diagnosed at our institution to analyze the patterns and outcomes. We also revised the diagnosis according to the new classification proposed by Romanini et al to facilitate future treatments as well as to propose an improvement in the assessment and initial behavior when PS is suspected.

Poland's syndrome is characterized by hypoplasia or absence of the breast or nipple, hypoplasia of subcutaneous tissue, absence of the costosternal portion of the pectoralis major muscle, absence of the pectoralis minor muscle, and absence of costal cartilages or ribs 2, 3, and 4 or 3, 4, and 5. Clinical manifestations of Poland's syndrome are extremely variable and rarely are all the features recognized in one individual. Depending on the physician's specialty and the referral pattern, a variable incidence of the anomalous defects is recognized. Syndactyly or bony abnormalities of the forearm are seldom treated by thoracic surgeons.

BACKGROUND: Poland syndrome is a congenital nongenetic anomaly characterized by unilateral chest wall hypoplasia, ipsilateral hand abnormalities, and hemivertebrae. It has not ben described so far in the fetus. CASE: The patient was referred for suspected left-arm hypomelia at 22 weeks of gestation. On ultrasonography, we confirmed the presence of severe left-sided hypomelia and detected an asymmetry of the rib cage and 3 thoracic hemivertebrae. The absence of heart defects led us to make the putative diagnosis of Poland syndrome. After termination of pregnancy, the diagnosis was confirmed by the pathologist. CONCLUSION: The possibility of diagnosing Poland syndrome in utero is important for proper management and counseling. If the syndrome is suspected in a fetus, counselors may refer to specific postnatal data to provide the couple with survival rates, treatment options, and results and morbidity figures. If the pregnancy is terminated, a detailed necropsy is warranted to confirm the diagnosis because familial transmission has been reported.

The Temnospondyli are a large and diverse group of stem-tetrapods (sensu Laurin and Reisz 1997) known from the Early Carboniferous to the Early Cretaceous; their remains have been found on all continents, from Greenland to Antarctica. The Metoposauridae are a short-ranging temnospondyl group recorded only from the Late Triassic; they are characterized by an anterior position of the orbits, a broad parasphenoid and a large quadrate foramen. However, unclear is the taxonomic value of the external location of tusks on the dentary. Our analysis of tooth rows in Metoposaurus diagnosticus krasiejowensis from the Triassic (Late Carnian) of Krasiejow (Silesia, SW Poland) shows that the external location of tusks on the dentary is not a synapomorphy for Metoposauridae but a character of great intraspecific variability. Variability of the arrangement of the internal tooth row on the upper jaw has also been observed.

Poland syndrome is characterized by unilateral aplasia or hypoplasia of the sternocostal portion of the pectoralis major muscle and ipsilateral syndactyly. In some cases other associated anomalies, including renal malformations, dextrocardia, and vertebral abnormalities, have been reported. We report a 7-month-old girl with Poland syndrome who also presented with ipsilateral renal agenesis. This report suggests that renal structural anomaly may be an integral part of this syndrome. We recommend renal imaging studies be performed on all children with Poland syndrome.

Poland's anomaly is comprised of a constellation of anomalies. To be included in the syndrome, a child must have a deficiency of the pectoralis major and minor muscles and an associated anomaly of either the ipsilateral breast or hand. Associated defects may include syndactyly osseous and cartilagenous costal aplasia and adactyly. A case of hepatic exstrophy through a full-thickness chest wall defect in an infant with Poland's anomaly is reported.

BACKGROUND: The primary site of pathology in Moebius syndrome is still unknown, although several studies have variably localized the lesion in the extraocular muscles, cranial nerves, or central nervous system. CASE: A 24-year-old man with Poland-Moebius syndrome and acquired progressive bilateral paralytic lower eyelid ectropion is described. OBSERVATIONS: In this patient, magnetic resonance imaging studies revealed a barely detectable pontine hypoplasia and normal recti muscles. Nerve conduction studies of the facial nerves showed a severe demyelinating or dysmyelinating type of neuropathy. Bilateral lower eyelid ectropium of the patient was successfully corrected by canthal tightening procedures. CONCLUSION: Contrary to many reported cases, this patient serves as a rare example of a progressive type of Poland-Moebius syndrome presumably resulting from a combination of a brainstem abnormality and a peripheral neural degenerative process.

Most common anomalies associated with Poland's syndrome are in the chest wall. This type of anomaly causes important psychological distress, especially in adolescent girls. A 19-year-old female with Poland's syndrome having psoriatic plaques on her trunk, knees, and elbows is reported in this paper. Such an association of Poland's syndrome with psoriasis has not been described previously.

The identification of depositional conditions and stratigraphical position of glacigenic deposits in the Nap?kw area is important for the genetic and stratigraphical interpretation of Quaternary deposits in the central part of the Holy Cross Mountains, as well as for a revision of the course and extent of Middle Polish (Saalian) glaciations. These deposits comprise a series of diamictons which occur between sandy-gravelly deposits. Based on results of macro- and microscopic sedimentological investigations, analysis of heavy mineral composition, roundness and frosting of quartz grains, as well as OSL dating, this complex must have formed during the Odranian Glaciation (Drenthe, Saalian, MIS 6). Sandy-gravelly deposits are of fluvioglacial and melt-out origin. Diamictons represent subglacial traction till. Their facies diversity is a result of variations in time and space, complex processes of deposition and deformation, responsible for their formation at the base of the active ice sheet. This glacigenic depositional complex was transformed by erosion-denudation and aeolian processes in a periglacial environment during the Vistulian (Weichselian, MIS 5d-2).
