‘Chronophilia’: Entries of Erotic Age Preference into Descriptive Psychopathology

A scientific nomenclature of erotic age preferences informed the mid- through late nineteenth century joint appearance of homosexuality and sexual abuse of minors on the medico-legal scene. Yet, even in the twenty-first century, legal, psychiatric and culture-critical dimensions of related terms are rarely cleanly distinguished. Review of primary sources shows the ongoing Western suspension of notions of ‘sick desire’, alongside and beyond the medicalisation of homosexuality, between metaphor, legal interdiction and postulated psychopathology. Virtually all early attention to erotic age preference occurred in the context of emergent attention to erotic gender preference. Age of attraction and age difference centrally animate modern homosexuality’s pre-modern past; its earliest psychiatric nomenclature and typologies (1844–69); its early aetiologies stipulating degrees of sexual differentiation (1890s); its concomitant sub-classification (1896–1914); its earliest psychophysiological tests (1950s); and, finally, its post-psychiatric, social scientific typologies (1980s). Several identifications of ‘paedophilia’ were seen throughout the 1890s but as a trope it gained cultural momentum only during, and as a seemingly intriguing corollary of, the progressive depsychiatricisation of homosexuality across the Anglo-European world (late 1950s through 1980s). Early twentieth century sources varied in having it denote (1) a distinct perversion, thus possible ‘complication’ of sexual inversion (2) a discrete corollary of psychosexual differentiation akin to gender preference (3) a distinct subtype of fetishism, thus a likely imprint of early seduction (4) a more intricate expression of erotic symbolism or psychosexual complex or (5) a taste answering to culture, a lack of it, or a libertine disregard for it.     

Histopathological growth patterns of resected non-colorectal,non-neuroendocrine liver metastases: a retrospective multicenter study

Background

Distinct Histopathological Growth Patterns can be identified in liver metastases from melanoma, breast and colorectal cancers. For each of these distinct liver metastasis types the HGP has proven a biomarker for survival after partial hepatectomy, with the desmoplastic type marking favourable prognosis. Whether HGPs can be considered a pan-cancer phenomenon remains unknown. This study therefore evaluates the presence of HGPs and their prognostic value across non-colorectal non-neuroendocrine liver metastases.

Methods

A retrospective multicentre cohort study was performed in patients who underwent curative intent resection of non-colorectal non-neuroendocrine liver metastasis. HGPs were assessed on Haematoxylin and Eosin slides according to consensus guidelines and classified as desmoplastic or non-desmoplastic. Overall- and recurrence-free survival were evaluated using Kaplan–Meier and multivariable Cox regression analysis.

Results

In total, 132 patients with liver metastasis from 25 different tumour types were eligible for analysis, of which 26 (20%) had a desmoplastic HGP. Five-year OS and RFS (95%CI) were 53% (36–78%) versus 40% (30–53%), and 33% (19–61%) versus 15% (9–27%) for patients with desmoplastic compared to non-desmoplastic metastases, respectively (p?=?0.031 & p?=?0.004). On multivariable analysis (adjusted HR [95%CI]) a desmoplastic HGP was prognostic for both OS (0.46 [0.25–0.86]) and RFS (0.38 [0.21–0.69]).

Conclusions

This study demonstrates that HGPs apply to liver metastases across a wide variety of primary tumour origins. They hold a prognostic value in these cases, suggesting that HGPs could represent a pan-cancer biomarker for survival after surgical resection of liver metastases.

     

Abrupt awakening phenomenon associated with gamma-hydroxybutyrate use: a case series

Case reports mention a sudden awakening from GHB-associated coma but do not specify its time course. The aim of the present case series was to investigate the time course of the awakening from GHB intoxication and the relationship to plasma concentrations of GHB and the presence of other drugs. Unconscious (GCS or=12 was 30 minutes (range 10 to 50 minutes). A subgroup of five patients had a GCS of 3 upon arrival and remained at 3 for a median time of 60 minutes (range 30 to 110 minutes), while the median time for the transition between the last point with GCS 3 and the first with GCS 15 was 30 minutes (range 20 to 60 minutes). This case series illustrates that patients with GHB intoxications remain in a deep coma for a relatively long period of time, after which they awaken over about 30 minutes. This awakening is accompanied by a small change in GHB concentrations. A confounding factor in these observations is co-ingested illicit drugs.     

A 3-year evolution of linguistic disorders in aphasia after stroke

Aphasia recovery after stroke has been the subject of several studies, but in none the deficits on the various linguistic levels were examined, even though in the diagnosis and treatment of aphasia the emphasis lays more and more on these linguistic level disorders. In this observational prospective follow-up study, we explored whether it is meaningful to investigate the recovery of semantics, phonology, and syntax separately. Fifteen patients with aphasia poststroke were assessed at 3 and 10 days, 7 weeks, 4 and 7 months, and 3 years postonset with the ScreeLing, a linguistic level test, the Aphasia Severity Rating Scale (spontaneous speech) and the Token Test. Group results showed improvement for the overall ScreeLing (P<0.01) and its subparts semantics (P<0.01) and syntax (P<0.01) up to 7 weeks, just as the Token Test (P<0.01). Phonology improved up to 4 months (P<0.05) and spontaneous speech up to 7 months (P<0.05). The recovery pattern of the three linguistic levels did not follow a parallel course, with a great deal of variability in linguistic recovery curves between and within patients. These results suggest that it is meaningful to assess the recovery of the linguistic levels separately, starting from the acute stage poststroke.     

The effect of open lung ventilation on right ventricular and left ventricular function in lung-lavaged pigs

Introduction  

Ventilation according to the open lung concept (OLC) consists of recruitment maneuvers, followed by low tidal volume and high positive end-expiratory pressure, aiming at minimizing atelectasis. The minimization of atelectasis reduces the right ventricular (RV) afterload, but the increased intrathoracic pressures used by OLC ventilation could increase the RV afterload. We hypothesize that when atelectasis is minimized by OLC ventilation, cardiac function is not affected despite the higher mean airway pressure.     

Next generation sequencing in synovial sarcoma reveals novel gene mutations

Over 95% of all synovial sarcomas (SS) share a unique translocation, t(X;18), however, they show heterogeneous clinical behavior. We analyzed multiple SS to reveal additional genetic alterations besides the translocation. Twenty-six SS from 22 patients were sequenced for 409 cancer-related genes using the Comprehensive Cancer Panel (Life Technologies, USA) on an Ion Torrent platform. The detected variants were verified by Sanger sequencing and compared to matched normal DNAs. Copy number variation was assessed in six tumors using the Oncoscan array (Affymetrix, USA). In total, eight somatic mutations were detected in eight samples. These mutations have not been reported previously in SS. Two of these, in KRAS and CCND1, represent known oncogenic mutations in other malignancies. Additional mutations were detected in RNF213, SEPT9, KDR, CSMD3, MLH1 and ERBB4. DNA alterations occurred more often in adult tumors. A distinctive loss of 6q was found in a metastatic lesion progressing under pazopanib, but not in the responding lesion. Our results emphasize t(X;18) as a single initiating event in SS and as the main oncogenic driver. Our results also show the occurrence of additional genetic events, mutations or chromosomal aberrations, occurring more frequently in SS with an onset in adults.
