Modernism, modernity, and politics in the general history of science: Implications of Herbert Mehrtens' work, from "Vienna 1900" to the Nazi era, and beyond.

Herbert Mehrtens' work and the implications of the historical ideas he advanced went beyond the history of any single discipline. The article therefore addresses three broad issues: (1) Mehrtens' reconceptualization of mathematical modernism, in his field-changing book Moderne-Sprache-Mathematik (1990) and other works, as an epistemic and cultural phenomenon in a way that could potentially reach across and also beyond the sciences and also link scientific and cultural modernisms; (2) the extension of his work to the history of modernity itself via the concept of "technocratic modernism"; (3) his seminal contributions to the historiography of the sciences and technology during the National Socialist period, focusing on his critique of claims that mathematics, the natural sciences and technology were morally or politically "neutral" during or after the Nazi era, and on his counter-claim that mathematicians and other scientists had in fact mobilized themselves and their knowledge in support of Nazism's central political projects. Taken as a guide for understanding science-politics relations in general, Mehrtens' work was and remains a counterweight to the political abstinence adopted by many who have followed the "cultural turn" in history of science and technology. In the broadest sense, the article is a plea for the culturally relevant and politically engaged historiography of the sciences and humanities that Mehrtens himself pursued.

An epistemology of empathy and modern methods of social research: Intimations of the mind and early Chicago sociology.

Empathic qualitative methods have become emblematic of early Chicago sociology. Yet methods were not formalized through the early 20th century and empathy was not in usage as a term. Only at mid-20th century did methodological formalization in sociology begin to occur, and an additional quarter-century passed before writing about empathy in sociological methods began to crystallize. Nevertheless, a portion of early Chicago sociologists, assimilating pragmatist thought, established a framework for the deployment of empathic acumen. Because empathy involves understanding others, it is argued that it is central to the study of social life. The article contends that understanding empathy must be as central to the social scientist's knowledge as it is to the effective deployment of research methods: a competent quest to generate knowledge about social life is premised on empathy. To heighten awareness of empathy, an epistemology is necessary. To this end, the article examines empathy as situated by a set of organizational and historical conditions that account for its origin and ascendance as a prescriptive characteristic of sociological work. The author draws attention to the significance of suffering and suggests that its religious precepts are transmuted for the conditions under which sociology develops in turn-of-the-century Chicago.

Evaluation of Efficacy of Herbert Bone Screw and Lag Screw in Management of Oblique Mandibular Fractures: A Prospective Randomized Comparative Study.

Purpose: To assess the efficacy of Herbert cannulated bone screw versus Lag screw in fixation of oblique mandibular fractures. Materials and Method: Study composed of two groups of 20 patients each and descriptive statistics were performed with p value set at 0.05 with confidence interval of 95%. Group A was treated by Titanium Lag screws; while, Group B was treated by Titanium Herbert Cannulated Bone Screws for the management of oblique mandibular fractures. Postoperatively, all the patients were evaluated clinically and radiographically by recording the incidence of complications (if any) which included trismus, neurosensory deficit, swelling, infection. Parameters such as occlusal discrepancy, rigid fixation (interfragmentary gap) and duration of surgery were also recorded for all the patients. Results: All the patients were followed for a period of three months. Difference in mouth opening was found to be statistically significant during 1st month follow-up (p-Value-0.002). Postoperatively, the mean interfragmentary gap in Group A was significantly more than Group B (p-Value-0.000). Other parameters like neurosensory deficits, occlusal discrepancies, chewing efficiency, stability of fractured fragments and post-operative complications in terms of swelling, hardware exposure, radiolucency surrounding screw and wound dehiscence did not show any statistically significant difference. Conclusion: The obtained results showed that both lag screws and Herbert cannulated bone screws fulfill the treatment goals of adequate reduction, fixation and stabilization of oblique mandibular fractures. Herbert screws have shown to have better results in terms of interfragmentary gap reduction as compared to lag screws.

Buck technique supplemented by temporary intersegmental pedicle screw fixation to repair lumbar spondylolysis in youth.

BACKGROUND: Lumbar spondylolysis is a bone defect in the pars interarticularis of the lumbar vertebral, which is a common cause of low back pain in youth. Although non-surgical treatment is a mainstream option, surgery is necessary for patients with persistent symptoms. Buck technique is widely used as a classical direct repair technique, but it cannot achieve reduction of low-grade spondylolisthesis and reconstruction of lumbosacral sagittal balance. We have described a novel surgical procedure based on Buck technique with temporary intersegmental pedicle screw fixation, and report a series of clinical outcomes in 5 patients to provide a reference for the clinical treatment of young lumbar spondylolysis. METHODS: Five young patients with symptomatic lumbar spondylolysis with a mean age of 19.20 ± 5.41 years underwent surgical treatment after an average of 7.60 ± 1.52 months of failure to respond to conservative treatment, using a new surgical procedure based on Buck technique combined with temporary intersegmental pedicle screw fixation. RESULTS: Five patients were successfully operated without serious complications such as nerve and vascular injury. The average operation time was 109.00 ± 7.42 min, the interpretative average blood loss was 148.00 ± 31.14 ml, and the average fusion time was 11.20 ± 1.64 months. All patients were followed up for 2 years after surgery, and the visual analogue score (VAS) of low back pain and Oswestry disability index (ODI) scores were significantly improved compared with those before surgery, and the Henderson's evaluation were rated excellent or good. After the removal of the internal fixation, it was observed that temporary intersegmental fixation could repair the isthmus, reduce lumbar spondylolisthesis, and reconstruct the sagittal balance of the lumbosacral vertebrae while preserving lumbar motion and preventing intervertebral disc degeneration. Postoperative MRI indicated the Pfirrmann classification of the affected discs: 1 case from grade III to grade II, 3 cases from grade II to grade I, and 1 case remained grade II. CONCLUSIONS: Buck technique supplemented by temporary intersegmental pedicle screw fixation is a highly applicable and effective method for the treatment of adolescent lumbar spondylolysis. The isthmic fusion is accurate, and temporary intersegmental fixation can effectively prevent disc degeneration and reconstruct the sagittal balance of lumbosacral vertebra.

Herbert Major on the insula: An early depiction of von Economo neurones?

Herbert Major (1850-1921) undertook histopathological studies of human and non-human primate brains at the West Riding Lunatic Asylum in Wakefield, England, during the 1870s. Two of his papers specifically investigated the structure of the island of Reil, or insula, "with the view of ascertaining its exact structure". In addition to describing and illustrating its lamination as six-layered, Major also identified "spindle-shaped" cells in the lower layers of human brains, but not in non-human primates. His written description, including measurements of cell body size, and illustration are suggestive that these were the neurones later described in the frontoinsular and anterior cingulate cortex by Constantin von Economo and Georg N. Koskinas and which were subsequently given the eponym "von Economo neurones". von Economo noted that this special neuronal type had been previously seen by Betz (1881), Hammarberg (1895), and Ramón y Cajal (1899-1904), but he did not mention Major's works. Major also ascribed linguistic functions to the insula. Hence, with respect to both anatomical and physiological features, Major may have pre-empted the findings of later research on this structure.

Subvastus Arthrotomy and Multifaceted Fixation in Medial Femoral Comminuted Hoffa's Fracture: A Case Report.

In managing orthopedic trauma, Hoffa's fracture, a rare intra-articular fracture affecting the femoral condyle, presents a unique challenge. We report a case of a 45-year-old male patient who had a traumatic injury and complained of substantial knee discomfort and limited range of motion. The patient had a medial femoral comminuted Hoffa's fracture. Subvastus arthrotomy was employed to handle the fracture successfully, and then a locking reconstruction plate, Herbert screws, and 4 mm cannulated screws were used for precise reduction and fixation. At the one-year follow-up, the patient showed acceptable postoperative results, including recovered knee function and radiographic indications of fracture repair.

A Partial Frontal Fracture of the Humeral Trochlea: A Case Report.

Fractures of the lower end of the humerus are uncommon but serious, potentially compromising elbow function. This article reports the case of a young patient with a fracture of the inner cheek of the humeral trochlea, resulting from a public road accident. The diagnosis was established by radiography and CT scan, confirming a displaced fracture associated with an avulsion fracture of the coronoid process. Surgical treatment was carried out with fixation of the osteochondral fragment and evacuation of the intra-articular fragments. Two months after the operation, the patient regained good joint function with a resumption of professional activity.

Corneal pannus, Herbert's pits and conjunctival inflammation in older children in Papua New Guinea.

PURPOSE: The prevalence of trachomatous inflammation-follicular (TF) in Papua New Guinea (PNG) suggests antibiotic mass drug administration (MDA) is needed to eliminate trachoma as a public health problem but the burden of trichiasis is low. As a result, WHO issued bespoke recommendations for the region. If ≥ 20% of 10-14-year-olds have both any conjunctival scarring (C1 or C2 or C3) and corneal pannus and/or Herbert's pits, MDA should be continued. Equally, if ≥ 5% of that group have both moderate/severe conjunctival scarring (C2 or C3) and corneal pannus and/or Herbert's pits, MDA should be continued. METHODS: We identified 14 villages where > 20% of 1-9-year-olds had TF during baseline mapping undertaken 4 years and 1 month previously. Every child aged 10-14 years in those villages was eligible to be examined for clinical signs of corneal pannus, Herbert's pits and conjunctival scarring. A grading system that built on existing WHO grading systems was used. RESULTS: Of 1,293 resident children, 1,181 (91%) were examined. Of 1,178 with complete examination data, only one (0.08%) individual had concurrent scarring and limbal signs. CONCLUSIONS: The WHO-predefined criteria for continuation of MDA were not met. Ongoing behavioural and environmental improvement aspects of the SAFE strategy may contribute to integrated NTD control. Surveillance methods should be strengthened to enable PNG health authorities to identify future changes in disease prevalence.

A misinterpreted psychoanalyst: Herbert Silberer and his theory of symbol-formation.

The primary aim of this article is to give a more detailed exposition of the cultural, personal, and theoretical contexts in which the Viennese psychoanalyst, Herbert Silberer's theories were born. When assessing the broader picture that this approach offers, it can be concluded that Silberer was an innovative thinker who inspired several of his contemporaries. Recognized in many respects by the society and scholars of this time, he represented quite a different viewpoint that was significantly influenced by several forms of Western esoteric thinking. Yet his main aim was to contribute to the field of psychoanalysis and develop a theory in which rationalistic psychoanalytic interpretations were combined with nonreductive approaches to mystical experiences. Silberer's name is frequently mentioned in a specific context in which his tragic suicide is emphasized rather than his innovations. Upon evaluating the materials recording Silberer's private life, it seems very likely that his suicide was not triggered by the criticism of Freud alone. Silberer's family affairs, his relationship with his father, and his financial and professional struggles could have all contributed to his tragic decision. This paper contends that Silberer's oeuvre deserves greater attention and must be evaluated based upon its own merit.

Herbert Coddington Major (1850-1921).

Herbert Coddington Major (Fig. 1) was a late nineteenth century pioneer in neuropathology and comparative neurology. No previous biographical article has been identified, suggesting he is now almost totally, yet unjustifiably, forgotten.
