Vessel depletion is often a terrifying finding that creates the need for novel approaches to access vessels that lie outside the anatomical region of the head and neck. We present what is, to our knowledge, the first case of utilising the subclavian artery and vein in head and neck reconstruction. We describe the anatomical details and a step-by-step access approach, together with tips on how to perform safe and effective microvascular anastomoses. The quality of the subclavian vessels is excellent, and access to the area is straightforward provided it is carefully planned. The technique could be considered more often in the vessel-depleted neck.
To explore how subjective and objective sleep parameters respond to bilateral subthalamic nucleus-deep brain stimulation (STN-DBS) in patients with Parkinson's disease (PD).
Thirty DBS sleep studies were included by searching PubMed, Embase, and the Cochrane Library, and only 21 prospectively designed studies, including 541 patients, were eligible for the main analysis. We evaluated sleep disturbance using 1 objective measurement, polysomnography (PSG), and 4 subjective scales, including PD Sleep Scale (PDSS), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and restless legs syndrome (RLS). We pooled data using the standard mean difference (SMD). The primary outcome was a change in sleep parameters 6 months postoperatively. Outcomes from <12 months to ≥12 months follow-up were compared in the subgroup analysis. Meta-regression was further conducted.
STN-DBS significantly improved all 4 subjective sleep scales in the 6-month follow-up ESS (SMD=0.234), PDSS (SMD=0.724), PSQI (SMD=1.374) and RLS (SMD=1.086), while most PSG parameters remained unchanged, except for shortened rapid eye movement sleep latency (RSL) (SMD=0.520). In the over-12-month follow-up, improvement persisted in PDSS but not in ESS. Dopamine drug reduction (p=0.009) and motor improvement (p=0.036) were correlated with ESS improvement and PDSS improvement, respectively.
Bilateral STN-DBS continuously improved subjective nocturnal sleep, while its effect on ESS lasted for only 1 year. Medication reduction and motor improvement may contribute to improved daytime sleepiness and better subjective nocturnal sleep, respectively. Except for a shortened RSL, STN-DBS did not change PSG parameters, including sleep efficiency and sleep architecture.

Abdominal pain due to acute appendicitis in one of the most causes of access to Emergency Room requiring surgical consult and treatment. The occurrence of anatomical anomalies should be considered especially when clinical and imaging features are misleading. In these cases laparoscopic surgery can be a safe tool in order to confirm uncertain diagnosis.
We report a case of acute appendicitis in a 23-year-old Caucasian men with situs viscerum inversus detected on radiological investigation. Laparoscopic approach was used to confirm the diagnosis and to perform appendectomy. Trocars placement was tailored for this peculiar case.
One third of patient with acute appendicitis complains abdominal pain in an unexpected location due to various anatomical position of appendix. Left-sided acute appendicitis is a cause of misdiagnosis and it can occur in association with anatomical anomalies such as situs viscerum inversus and midgut malrotation. Laparoscopic surgery may represent a valuable approach in terms of differential diagnosis and treatment in these patients.
Left-sided acute appendicitis should always be considered in young male patients with left lower quadrant pain. Laparoscopic approach is useful and safe procedure both for diagnosis and treatment of these unclear clinical pictures.

Conventional therapies, in addition to the high cost, have many adverse effects and cases of parasite's resistance. Chalcones are secondary metabolites precursors in the flavonoid pathway and can be obtained naturally, but with low yield from plant raw material. Thus, the use of synthetic chalcones has been a promising strategy for the development of molecules with leishmanicidal activity. Thus, this work aimed to develop a controlled release system of two synthetic chalcone (trans-chalcones and 3'-(trifluormethyl)-chalcone) using polyvinyl alcohol nanofibers (PVA) as scaffold. The association of chalcones to the nanofibers was made by nanoemulsions (NE) thereof, i.e., a colloidal system on a nanometric scale, which allows compounds with opposite polarities to remain miscible and stable throughout their manipulation. Chalcone nanoemulsions were developed using the spontaneous emulsification technique. The NE were characterized regarding their parting chalcone were retained in the epidermis and dermis. This result is thought to be relevant, since parasites are located mainly in the dermis. Further, in vitro assay against the amastigote form of L. (L) amazonensis, showed IC50 values to trans-chalcone and 3'-(trifluormethyl)-chalcone of 24.42 ± 6.76 μg.mL-1 and 15.36 ± 4.61 μg.mL-1, respectively. In addition to improving the solubility of the compounds tested in culture medium without using organic solvents, chalcones in nano-emulsified form reduced the IC50 to 9.09 ± 1.24 μg.mL-1 (trans-chalcone) and 10.27 ± 2.27 μg.mL-1 (3'-(trifluormethyl)-chalcone) which confirmed the potential of the nanoemulsion containing chalcone for cutaneous leishmaniasis treatment.
Lung transplantation is increasingly performed in recipients aged ≥65 years. However, the risk factors for mortality specific to this population have not been well studied. In lung transplant recipients aged ≥65 years, we sought to determine post-transplant survival and clinical factors associated with post-transplant mortality.
We investigated 5,815 adult lung transplants recipients aged ≥65 years in the Scientific Registry of Transplant Recipients. Mortality was defined as a composite of recipient death or retransplantation. learn more The Kaplan-Meier method was used to estimate the median time to mortality. Univariable and multivariable Cox proportional hazards regression models were used to examine the association between time to mortality and 23 donor, recipient, or center characteristics.
Median survival in lung transplant recipients aged ≥65 years was 4.41 years (95% CI 4.21-4.60 years) and significantly worsened by increasing age strata. In the multivariable model, increasing recipient age strata, creatin with single lung transplantation. Our results support that after careful consideration of risk factors, lung transplantation can provide life-extending benefits in individuals aged ≥65 years.The COVID-19 outbreak is a global problem affecting the world in many respects. In the medical field, its impact on surgical branches as well as clinical branches is inevitable. From the plastic surgery perspective, the COVID-19 outbreak affects the number and distribution of surgeries, patient admissions and educational activities. Although these impacts are predictable, it is beneficial to document these data that would contribute to the proper response to a similar crisis in the future. From this standpoint, the present study aims to analyze the effect of the COVID-19 pandemic on plastic surgery practice in some aspects. Epidemiologic data of the two-time frames, routine period, and pandemic period of plastic surgery were reviewed retrospectively. The ratios of the listed data were compared between the two periods; admissions to the outpatient clinic, surgeries, consultations, anesthesia type, hospitalizations, and demographic data. While the number of outpatient clinic patients was 3511 in the routine period, it was 490 in the pandemic period. Compared to the routine period, the number of surgical interventions was decreased from 793 to 129 during the pandemic period. In particular, a statistically significant increase was observed in the rate of hand trauma and maxillofacial trauma cases during the pandemic period compared with the routine period (p less then 0.001, and p = 0.032, respectively). Therefore, high rates of hand trauma and maxillofacial trauma should be taken into consideration when making arrangements such as personnel distribution, use of medical resources, and regulation of hospital infrastructure in extraordinary situations like COVID-19 pandemics.Chikungunya virus (CHIKV) is an arthropod-borne virus that has re-emerged recently and has spread to previously unaffected regions, resulting in millions of infections worldwide. The genus Alphavirus, in the family Togaviridae, contains several members with a similar potential for epidemic emergence. In order for CHIKV to replicate in targeted cell types it is essential for the virus to enter these cells. In this review, we summarize our current understanding of the versatile and promiscuous steps in CHIKV binding and entry into human and mosquito host cells. We describe the different entry pathways, receptors, and attachment factors so far described for CHIKV and other mosquito-borne alphaviruses and discuss them in the context of tissue tropism and potential therapeutic targeting.
Deregulation of polymorphonuclear neutrophils (PMNs) is an essential step in the development of inflammatory complications upon trauma. Different neutrophil subtypes have been identified recently, however, the role of neutrophil subtypes in immunoregulation upon trauma is unclear. We hypothesize that extensive trauma surgery causes instant progressive heterogeneity of the blood neutrophil pool, and increased appearance of young(CD16

) neutrophils in peripheral blood.
A standardized extensive thoraco-abdominal porcine trauma surgery model was utilized, and 12 animals were included. Blood was collected at defined timepoints and neutrophil numbers and subtypes were studied by flowcytometry. Neutrophil subtypes were identified by differences in cell surface expression levels of CD16 (FcγRIII) and CD62L (L-selectin). Porcine neutrophil subtypes were further characterized after flow sorting.
Eleven animals survived the 3-hour surgical protocol. Neutrophil numbers dropped significantly from a mean of role in the development of early organ failure upon extensive trauma surgery. This for the first time exemplifies experimentally the time constraints and impact of damage control surgery after severe trauma.
Standardized extensive trauma surgery was associated with instant progressive neutropenia and increased heterogeneity of the blood neutrophil pool. Furthermore, three different neutrophil subsets in peripheral porcine blood were identified over the course of surgery. Further studies should clarify their precise role in the development of early organ failure upon extensive trauma surgery. This for the first time exemplifies experimentally the time constraints and impact of damage control surgery after severe trauma.
