Men’s circumcision is in many countries considered as a hygienic-cosmetic or aesthetic treatment. However, it still remains in close connection with religious rites (Judaism, Islam) and is still practiced all over the world. During the Second World War the visible effects of circumcision became an indisputable evidence of being a Jew and were often used especially by the so-called szmalcownicy (blackmailers). Fear of the possibility of discovering as non-Aryan prompted many Jews hiding on the so-called Aryan side of Warsaw to seek medical practitioners who would restore the condition as it was before the circumcision. The reconstruction surgery was called in surgical jargon “knife baptizing”. Almost all of the procedures were performed by Aryan doctors although four cases of hiding Jewish doctors participating in such procedures are known. Surgical technique consisted of the surgical formation of a new foreskin after tissue preparation and stretching it by manual treatment. The success of the repair operation depended on the patient’s cooperation with the doctor, the worst result was in children. The physicians described in the article and the operating technique are probably only a fragment of a broader activity, described meticulously by only one of the doctors – Dr. Janusz Skórski. This work is an attempt to describe the phenomenon based on the very scanty source material, but it seems to be the first such attempt for several decades.

Postural sway has been demonstrated to increase following exposure to different types of motion. However, limited prior studies have investigated the relationship between exposure to normative on-road driving conditions and standing balance following the exposure. The purpose of this on-road study was to quantify the effect of vehicle motion and task performance on passengers’ post-drive standing balance performance. In this study, trunk-based kinematic data were captured while participants performed a series of balance exercises before and after an on-road driving session in real-time traffic. Postural sway for all balance exercises increased following the driving session. Performing a series of ecologically relevant visual-based tasks led to increases in most post-drive balance metrics such as sway position and velocity. However, the post-drive changes following the driving session with a task were not significantly different compared to changes observed following the driving session without a task. The post-drive standing balance performance changes observed in this study may increase vulnerable users’ risk of falling. Wearable sensors offer an opportunity to monitor postural sway following in-vehicle exposures.

Abstract Objective To compare the results of endoscopic and microscopic ossicular chain reconstruction surgery. Methods Patients undergoing ossicular chain reconstruction surgery via an endoscopic (n = 31) or microscopic (n = 34) technique were analysed for age, gender, Middle Ear Risk Index, ossicular chain defect, incision type, ossicular chain reconstruction surgery material, mean air conduction threshold, air–bone gap, air–bone gap gain, word recognition score, mean operation duration and mean post-operative follow up. Results Post-operative air conduction, air–bone gap and word recognition score improved significantly in both groups (within-subject p < 0.001 for air conduction and air–bone gap, and 0.026 for word recognition score); differences between groups were not significant (between-subject p = 0.192 for air conduction, 0.102 for air–bone gap, and 0.709 for word recognition score). Other parameters were similar between groups, except for incision type. However, endoscopic ossicular chain reconstruction surgery was associated with a significantly shorter operation duration (p < 0.001). Conclusion Endoscopic ossicular chain reconstruction surgery can achieve comparable surgical and audiological outcomes to those of microscopic ossicular chain reconstruction surgery in a shorter time.

Background: Reconstruction of the nose can be difficult due to its complex anatomical features. In 1989, Zitelli described a modified version of the bilobed flap design technique using 45° and 90° angles to improve nasal reconstructions. While the bilobed flap is still frequently referenced in scholarly literature, there seems to be inconsistency in preoperative flap design; these deviations can lead to suboptimal outcomes. The authors aim to illustrate the variability in bilobed flap execution and provide guidelines in preoperative design to improve consistency. Methods: A geometrically-based approach was used to characterize the inconsistency of bilobed repair technique. The pre-operative design images from fifteen scholarly articles were analyzed via a series of measurements and computations to quantify the angle of rotation and dimensions for the primary and secondary lobes. The “Error Quotient” was a calculated ratio that objectively measured the extent to which a bilobed design deviated from Zitelli’s specifications. Results: There was a noticeable variability in the design of both the primary and secondary lobes. Bilobed designs with smaller angles of rotation, particularly of the first lobe, were associated with higher Error Quotients and greater amounts of deviation from Zitelli’s design. Designs with the smallest Error Quotients had a primary lobe rotation that approached 45°. Conclusion: Consistency of application of the bilobed flap should be established to allow for optimal results, particularly with emphasis on design of the primary lobe. This can be accomplished by including a disposable protractor and marker in their sterile kit to measure a 45° rotation.

This study investigated whether artificial gravity (AG), induced by short-radius centrifugation, mitigated deterioration in standing balance and anticipatory postural adjustments (APAs) of trunk muscles following 60-day head-down tilt bed rest. Twenty-four participants were allocated to one of three groups: control group (N=8); 30 minutes continuous AG daily (N=8); intermittent 6x5 minutes AG daily (N=8). Before and immediately after bed rest, standing balance was assessed in four conditions: eyes open and closed on both stable and foam surfaces. Measures including sway path, root-mean-square, and peak sway velocity, sway area, sway frequency power, and sway density curve were extracted from the centre of pressure displacement. APAs were assessed during rapid arm movements using intramuscular or surface electromyography electrodes of the rectus abdominis, obliquus externus and internus abdominis, transversus abdominis, erector spinae at L1, L2, L3, and L4 vertebral levels, and deep lumbar multifidus muscles. The relative latency between the EMG onset of the deltoid and each of the trunk muscles was calculated. All three groups had poorer balance performance in most of the parameters (all P<0.05) and delayed APAs of the trunk muscles following bed rest (all P<0.05). Sway path and sway velocity were deteriorated, and sway frequency power was less in those who received intermittent AG than in the control group (all P<0.05), particularly in conditions with reduced proprioceptive feedback. These data highlight the potential of intermittent AG to mitigate deterioration of some aspects of postural control induced by gravitational unloading, but no protective effects on trunk muscle responses were observed.
