Complications arising from aesthetic surgery procedures in foreign countries and Switzerland.

BACKGROUND: Cosmetic surgery tourism has increased in popularity in recent years, with arising complications and post-operative follow-up care often managed in the client's home country, thereby burdening the Swiss health care system. METHODS: We retrospectively reviewed patients with complications after cosmetic surgeries abroad and in Switzerland who were treated at the University Hospital Zurich between 2015 and 2019. Data were collected from medical records and reviewed for patient characteristics, procedures, complications, and treatment modalities. RESULTS: A total of 228 patients (207 females and 21 males) were identified with female mean age of 40.9±12.0 years and male mean age of 34.3±8.9 years. Most complications were observed for procedures performed in Europe (69%) with only thirty-six patients (16%) experiencing complications due to a procedure undertaken in Switzerland. Breast surgery was the most frequently performed procedure (60%), followed by body contouring (17%) and facial surgery (12%). The most common complications occurring after surgeries abroad were pain and discomfort (19%) as well as aesthetic dissatisfaction (18%), followed by wound breakdown (14%) and infection (11%). Most patients (76%) were treated as outpatients and the treatment of all patients over the observed period cost the healthcare system $ 795,574. CONCLUSIONS: There is an ongoing trend of cosmetic surgery tourism leading to an increasing number of patients with complications requiring aftercare in Switzerland. In contrast to previous research, more men are seeking cosmetic surgery abroad and the most common complications, such as wound healing disorders and infection, descreased in favor of aethetic dissatisfaction, possibly indicating ameliorated patient aftercare abroad.

Expression and Cell Type-specific Localization of Inflammasome Sensors in the Spinal Cord of SOD1(G93A) Mice and Sporadic Amyotrophic lateral sclerosis Patients.

Inflammasomes are key components of the innate immune system and activation of these multiprotein platforms is a crucial event in the etiopathology of amyotrophic lateral sclerosis (ALS). Inflammasomes consist of a pattern recognition receptor (PRR), the adaptor protein apoptosis-associated speck-like protein containing a CARD (ASC) and caspase 1. Exogenous or endogenous "danger signals" can trigger inflammasome assembly and promote maturation and release of pro-inflammatory cytokines, including interleukin 1ß. Previous studies have demonstrated presence and activation of NLRP3 in spinal cord tissue from SOD1(G93A) mice and human sporadic ALS (sALS) patients. However, regulation and cell type-specific localization of other well-known PRRs has not yet been analysed in ALS. Here, we explored gene expression, protein concentration and cell type-specific localization of the NLRP1, NLRC4 and AIM2 inflammasomes in spinal cord samples from SOD1(G93A) mice and sALS patients. Transcription levels of NLRP1 and NLRC4, but not AIM2, were elevated in symptomatic SOD1(G93A) animals. Immunoblotting revealed elevated protein levels of NLRC4, which were significantly increased in sALS vs. control patients. Immunofluorescence studies revealed neuronal labelling of all investigated PRRs. Staining of AIM2 was detected in all types of glia, whereas glial type-specific labelling was observed for NLRP1 and NLRC4. Our findings revealed pathology-related and cell type-specific differences in the expression of subsets of PRRs. Besides NLRP3, NLRC4 appears to be linked more closely to ALS pathogenesis.
