AbstractWe present the case of the transformation of an enchondroma in the middle phalanx of the fourth finger of the left hand into a chondrosarcoma. The patient presented a lesion with clinical history, examination, and radiology findings consistent with an enchondroma, which was conservatively treated. Two years later, the patient came for a medical visit with a clinical and radiological variation of the lesion. Computed tomography scans and biopsy revealed a lesion with sarcomatous degeneration which was confirmed after the controlled amputation of the fourth finger. The malignant transformation potential of an enchondroma must be considered.

High Index Of Suspicion

Congenital diaphragmatic hernia (CDH) is a major malformation found in newborns and babies but rarely in adults. CDH is defined by the presence of a defect in the diaphragm, which permits the herniation of abdominal contents into the thorax. The diagnosis of CDH is based on clinical history, examinations and is confirmed by plain X-ray films and computed tomography scans. Here we report a case which was misdiagnosed at another centre as pleural effusion and managed by placement of intercostal tube drainage and later on diagnosed to be case of Morgnani-Larrey parasternal diaphragmatic hernia. Congenital diaphragmatic hernia (CDH) is a major malformation found in newborns and babies but rarely in adults. CDH is defined by the presence of a defect in the diaphragm, which permits the herniation of abdominal contents into the thorax. The diagnosis of CDH is based on clinical history, examinations and is confirmed by plain X-ray films and computed tomography scans. The purpose of reporting this case is to provide information on late-presenting CDH and to emphasize that a high index of suspicion is required for diagnosis and to avoid unwanted complications.

The Relationship

Abstract. The ratio of second to fourth finger length (2D:4D ratio) is sexually dimorphic with women having higher 2D:4D ratio than men. Recent studies on the relationship between 2D:4D ratio and gender-role orientation yielded rather inconsistent results. The present study examines the moderating influence of nationality on the relationship between 2D:4D ratio and gender-role orientation, as assessed with the Bem Sex-Role Inventory, as a possible explanation for these inconsistencies. Participants were 176 female and 171 male university students from Germany, Italy, Spain, and Sweden ranging in age from 19 to 32 years. Left-hand 2D:4D ratio was significantly lower in men than in women across all nationalities. Right-hand 2D:4D ratio differed only between Swedish males and females indicating that nationality might effectively moderate the sexual dimorphism of 2D:4D ratio. In none of the examined nationalities was a reliable relationship between 2D:4D ratio and gender-role orientation obtained. Thus, the assumption of nationality-related between-population differences does not seem to account for the inconsistent results on the relationship between 2D:4D ratio and gender-role orientation.

Abstract Objective Ventilation of the middle ear and mastoid air cells is believed to play an important role in the pathogenesis of chronic ear disease. Traditionally, ventilation is assessed by computed tomography. However, this exposes patients to cumulative radiation injury. In cases with a perforation in the tympanic membrane, tympanometry potentially presents a non-invasive alternative to measure the ventilated middle-ear and mastoid air cell volume. This study hypothesised that total tympanometry volume correlates with ventilated middle-ear and mastoid air cell volume. Method Total tympanometry volume was compared with ventilated middle-ear and mastoid air cell volume on computed tomography scans in 20 tympanic membrane perforations. Results There was a high correlation between tympanometry and computed tomography volumes (r = 0.78; p < 0.001). A tympanometry volume more than 2 ml predicted good ventilation on computed tomography. Conclusion These results may help reduce the need for pre-operative computed tomography in uncomplicated cases with tympanic membrane perforations.

The 2D: 4D digit ratio, the ratio of the length of the second finger to the length of the fourth finger, is often considered a proxy for testosterone exposure in utero. A recent study reported, among other things, an association between the left-hand 2D:4D and self-employment in a sample of 974 adults. In this preregistered study, we replicate the 2D:4D results on a sample of more than 2100 adults from the German Socioeconomic Panel-Innovation Sample (SOEP-IS). We find no statistically significant associations between 2D:4D and self-employment.
