[Sociological aspects of transgenrism]. / Aspects sociologiques des transidentités.

The surgery of trans people is not apprehended by most of plastic surgeons as a simple surgery for the purpose of morphological transformation. At the same time, the French trans population does not benefit from adequate surgical coverage. Over the past few years, French regulations have simplified the process of reassignment surgeries. In addition, we have witnessed a fairly rapid increase in requests for transition surgery with accelerated and sometimes atypical courses. In recent years, a number of specialists have warned the medical community about the risks of slippage due to a lack of psychological monitoring of certain people beginning a transition process. Quite recently, hybrid transition paths have also appeared which, from a surgical point of view, are no longer limited to ensuring that a native assigned female patient can take on the most masculine appearance possible or the reverse. In this manuscript, we expose the biological, historical and societal place of transidentity and then address the reasons for the warnings of a certain category of the medical population while reassuring the surgical community on the benefits of reassignment surgeries in a controlled context. We end by proposing a few ways to improve the care course of trans people applicable in France.

[Thoracic reassignment surgeries]. / Chirurgie de réassignation : techniques chirurgicales pour le thorax.

Thoracic reassignment surgeries are the most common gender reassignment surgeries. They represent the first and sometimes the only step in the reassignment process for transgender patients. Surgical techniques for thoracic reassignment derive from those used for the cisgender population and are accessible to plastic surgeons who do not usually treat transgender patients. On the other hand, there are some anatomical differences between men and women that they should understand, for instance, the positioning of the neo-NAC, the neo-inframammary fold and the scars. It is therefore important to understand these anatomical differences in order to optimize the cosmetic results of these surgeries so that they correspond to the expectations of these patients. In addition, the plastic surgeon will also have to be careful to adapt his approach to the relational level, with these patients, such as avoiding misgendering or using the "dead name". Finally, even if these operations are theoretically covered at 100% by the French health insurance, a request for prior agreement may be required in certain cases.

[The tube in tube thoracodorsal perforator flap phalloplasty]. / Phalloplastie par Lambeau perforant thoracodorsal « tube in tube ¼.

This article deals with a clinical case of a tube in a tube TDAP phalloplasty in a 38 years old trans-man. While penis reconstruction surgery aroused an efflorescence of different operative techniques, the resulting female to male surgery sees these procedures boil down to two or three flaps. If we usually discuss before surgery about the way to lengthen the urinary tract, as the way to implant later for intercourse; the choice of the donor site remains too systematized. Surgeons commonly focus on the reconstructed site prior to the donor site. In this case, laxity in the back and reliability of direct closure make us harvest the thoracodorsal perforator flap. Dissection of perforators saves muscular function and direct closure afford an aesthetic result less visible than a graft on the forearm. The thin flap we harvest allows tube in tube phalloplasty so that phallus and urethra are being built in the same time. One case has been reported in the literature of thoracodorsal perforator flap phalloplasty with grafted urethra, but no case of tube within a tube TDAP phalloplasty.

A comparative study of human exposures to household air pollution from commonly used cookstoves in Sri Lanka.

Solid fuel burning cookstoves are a major source of household air pollution (HAP) and a significant environmental health risk in Sri Lanka. We report results of the first field study in Sri Lanka to include direct measurements of both real-time indoor concentrations and personal exposures of fine particulate matter (PM2.5 ) in households using the two most common stove types in Sri Lanka. A purposive sample of 53 households was selected in the rural community of Kopiwatta in central Sri Lanka, roughly balanced for stove type (traditional or improved 'Anagi') and ventilation (chimney present or absent). At each household, 48-h continuous real-time measurements of indoor kitchen PM2.5 and personal (primary cook) PM2.5 concentrations were measured using the RTI MicroPEM™ personal exposure monitor. Questionnaires were used to collect data related to household demographics, characteristics, and self-reported health symptoms. All primary cooks were female and of an average age of 47 years, with 66% having completed primary education. Median income was slightly over half the national median monthly income. Use of Anagi stoves was positively associated with a higher education level of the primary cook (P = 0.026), although not associated with household income (P = 0.18). The MicroPEM monitors were well-received by participants, and this study's valid data capture rate exceeded 97%. Participant wearing compliance during waking hours was on average 87.2% on Day 1 and 83.3% on Day 2. Periods of non-compliance occurred solely during non-cooking times. The measured median 48-h average indoor PM2.5 concentration for households with Anagi stoves was 64 µg/m3 if a chimney was present and 181 µg/m3 if not. For households using traditional stoves, these values were 70 µg/m3 if a chimney was present and 371 µg/m3 if not. Overall, measured indoor PM2.5 concentrations ranged from a minimum of 33 µg/m3 to a maximum of 940 µg/m3 , while personal exposure concentrations ranged from 34 to 522 µg/m3 . Linear mixed effects modeling of the dependence of indoor concentrations on stove type and presence or absence of chimney showed a significant chimney effect (65% reduction; P < 0.001) and an almost significant stove effect (24% reduction; P = 0.054). Primary cooks in households without chimneys were exposed to substantially higher levels of HAP than those in households with chimneys, while exposures in households with traditional stoves were moderately higher than those with improved Anagi stoves. As expected, simultaneously measuring both indoor concentrations and personal exposure levels indicate significant exposure misclassification bias will likely result from the use of a stationary monitor as a proxy for personal exposure. While personal exposure monitoring is more complex and expensive than deploying simple stationary devices, the value an active personal PM monitor like the MicroPEM adds to an exposure study should be considered in future study designs.
