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.

Visual Deafferentation

Background and Objective: Charles Bonnet Syndrome (CBS) has been defined as complex visual hallucinations (CVH) due to visual loss. The underlying mechanism of CBS is not clear and the underlying pathophysiology of the visual hallucinations in CBS patients and pure visually impaired patients is still not clear. </P><P> Methods: In our study, we have scanned three patients with eye disease and CBS (VH+) and three patients with eye disease without CBS (VH-) using FDG-PET. Results: Our results showed underactivity in the pons and overactivity in primary right left visual cortex and inferior parietal cortex in VH- patients and underactivity in left Broca, left inf frontal primary visual cortex and anterior and posterior cingulate cortex in VH+ patients relative to the normative 18FFDG PET data that was taken from the database consisting of 50 age-matched healthy adults without neuropsychiatric disorders. Conclusion: From this distributed pattern of activity changes, we conclude that the generation of visual hallucination in CBS is associated with bottom-up and top-down mechanism rather than the generally accepted visual deafferentation-related hyperexcitability theory.

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.

Angle Of Rotation

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.

Insight Into

Charles Bonnet syndrome (CBS) is a condition where cognitively normal individuals with sight impairment experience simple and/or complex visual hallucinations. The exact pathogenesis of CBS is unknown; however, deafferentation is often recognised as a causal mechanism. Studies have provided insight into the multifaceted impact of CBS on wellbeing. Onset of CBS may cause distress among those believing visual hallucinations are indicative of a neurological condition. Hallucinatory content is often congruent with the emotional response. For example, hallucinations of a macabre nature typically result in a fearful response. Visual hallucinations may be highly disruptive, causing everyday tasks to become challenging. Clinical management relies on forewarning and pre-emptive questioning. Yet, knowledge and awareness of CBS is typically low. In this review, we provide a summary of the social and psychological implications of CBS and explore recent developments aimed at raising awareness and improving patient management.
