Nanodelivery of drugs aims to ensure drug stability in the face of adverse biochemical conditions in the course of administration, concomitant with appropriate pharmacological action provided by delivery at the targeted site. In this study, the application potential of a nanoparticle produced with biopolymers chitosan-N-arginine and alginate as an oral drug delivery material is evaluated. Both macromolecules being weak polyelectrolytes, the nanoparticle presents strong thermodynamic interactions with a biological model membrane consisting of a charged lipid liposome bilayer, leading to membrane disruption and membrane penetration of the nanoparticles in ideal conditions of pH corresponding to the oral route. The powder form of the nanoparticle was obtained by lyophilization and with a high percentage of entrapment of the anthelmintic drug praziquantel. In vivo studies were conducted with oral administration to Corydoras schwartzi fish with high intensity of intestinal parasites infection. The in vivo experiments confirmed the mucoadhesive and revealed membrane-penetrating properties of the nanoparticle by translocating the parasite cyst, which provided target drug release and reduction of over 97% of the fish intestinal parasites. Thus, it was evidenced that the nanoparticle was effective in transporting and releasing the drug to the target, providing an efficient treatment.
The ongoing COVID-19 pandemic has disproportionately affected patients who have undergone solid organ transplantation.

To analyze a cohort of transplant recipients in our practice who developed COVID-19, with a focus on immunosuppressive regimen, tacrolimus blood levels, clinical course, and patient and graft outcomes.

During the first 12 months of the pandemic, we identified patients diagnosed with SARS-CoV-2 infection among our ambulatory cohort, including kidney, liver, and heart transplant recipients. Baseline and follow-up data concerning graft function, immunosuppression details, and patient and graft outcomes were analyzed.

Of 2091 ambulatory patients, 201 (9.6%) with diagnosed SARS-CoV-2 infection were identified, including 112 kidney, 56 heart, and 33 liver transplant recipients. COVID-19 cases were significantly more common among those who had recently undergone kidney (during 2015-2020) or heart transplantation (during 2020) than earlier recipients. Additionally, blood levels of tacrolimus with recent kidney or heart transplantation, and results suggest the potential importance of immunosuppressive regimen strength for SARS-CoV-2 infection-related morbidity.
Geometric morphometrics (GM) is an advanced landmark-based quantitative method used to study biological shape and form. Historically, GM has been limited to non-biomedical fields such as comparative biology; however, this technique confers advantages over traditional cephalometric methods, warranting a review of current applications of GM to human craniofacial disorders.

The RISmed package was used to extract metadata associated with PubMed publications referencing GM analysis techniques in craniofacial and reconstructive surgery. PubMed search terms included "geometric AND morphometric AND craniofacial;" and "geometric AND morphometric AND reconstructive surgery." Duplicate search results were eliminated.

Search yielded 139 studies between 2005 and 2020, of which 27 met inclusion criteria. Human craniofacial studies constituted 2% of all queried GM studies. Among these, cleft lip and palate were the most commonly studied craniofacial conditions (7 studies, 26%), followed by sagittal craniosynostosis (4 of traditional cephalometric techniques, and hence may claim an expanded role in the study of human craniofacial disorders in clinical and research settings.
Anthropometrical analysis of the foramen magnum (FM) was conducted on a sample of 32 children and 101 adults excavated from Zaghunluq cemetery dating between 2600 and 1900 cal. yr BP in Xinjiang, China. The FM features of children during age changes and growth spurt periods were explored by comparing the length of the FM, the width of the FM, and the values of the FM index among different age groups. The data presented in this study indicate that the size of the FM was smallest at 2 years old, and the FM size during 5 to 7 years of age was close to that of adults, supporting the view that the size of the 6-year-old skull is close to that of the adult and brain growth appears to terminate at 7 years. The FM likely experiences a growth spurt period during 2 to 5 years of age. Regression equations were established by regression analysis of the length and width of the FM. Study on the morphological variation of the FM provides further information about the growth of children.

Maxillonasal dysplasia or Binder syndrome is an uncommon condition. It is a congenital disease characterized by undergrowth of the central face and may include elements of the nose and upper jaw. The hallmark of the deformity is a retruded mid-face and an extremely flat nose. The timing and the surgical approaches for management of such deformity are still controversial. In this paper, we are going to present our experience in management of Binder syndrome in children. Seven children ranging in age from 6 to 13 years with classic features of Binder syndrome were operated upon in this study. The surgical approach was done at an early age and included 3 main components; nasal dorsum augmentation by costal cartilage graft, maxillary augmentation by rib grafts and columellar reconstruction by VY-plasty and strut grafts. Patients were followed for up to 6 years. Excellent results were obtained in all patients with this surgical procedure. Half of our patients required more than 1 surgery but none of them requirethetic and alleviate the psychological upset without much disturbance of the facial growth.
Repairing the defects of face and neck remains a big challenge for plastic surgeons. check details Here we present a case series of pre-expanded cervico-acromial flaps in the repair of soft tissue defects.

This is a retrospective study that a total of 126 patients between 2001 and 2019 were included. One patient was excluded since he did not complete the treatment. All patients were followed for at least 0.5 years (range 0.5-4 years, mean 2.50 years) after surgery.

All patients are satisfied with the appearance. The color and texture of expanded flaps were similar to surroundings. One patient (0.8%) had complete necrosis and received skin grafts. The size of cervico-acromial was 26-10 × 14-6 cm (mean, 15.389 ± 2.701× 8.341 ± 1.075 cm). The time of operation during stage 1 was 59.254 ± 9.895 minutes, 96.912 ± 18.936 minutes during stage 2, and 38.146 ± 9.478 minutes during stage 3. Surgical complication rate was 14.3%, given that 18 patients had complications following the surgery.

The cercico-acromial flap is a reliable and multifunctional method for face, neck, and chest reconstruction.

Throat packs are used in a wide range of surgical and dental procedures. Indications for use include; airway stabilization, reducing the risk of aspiration, and postoperative nausea and vomiting. Despite these perceived benefits, a retained throat pack can be fatal. This has been highlighted since the 1970s but as of yet no effective fail-safe mechanisms exist to prevent the potential tragic consequences of a retained throat pack.A multifaceted questionnaire was distributed at the annual Craniofacial Society of Great Britain and Ireland 2017 to identify current views and practices amongst cleft surgeons. The questionnaire contained seventeen questions related to throat pack use. The responses to the questions were collated and discussed in the context of the current literature.Twenty-four cleft surgeons completed the questionnaire; 67% always use a throat pack, with 84% not securing the throat pack in any way. Almost half (48%) had encountered a serious adverse incident secondary to the use of a throat packe questionnaire contained seventeen questions related to throat pack use. The responses to the questions were collated and discussed in the context of the current literature.Twenty-four cleft surgeons completed the questionnaire; 67% always use a throat pack, with 84% not securing the throat pack in any way. Almost half (48%) had encountered a serious adverse incident secondary to the use of a throat pack.This survey and review of the literature highlight ongoing discrepancies and a lack of standardization on a national basis. Adverse incidents and fatalities are still occurring. Overwhelming evidence now confirms the lack of benefit regarding postoperative nausea and vomiting and the authors urge both surgeons and anesthetists to strongly consider the need for a throat pack in routine elective procedures.

Dermal filler injections, one of the most commonly performed procedures in facial esthetic surgery, are rising in popularity. This has also led to an increase in nonmedical grade filler injections performed by nonmedical personnel, including that of injectable silicone. Surgical removal of silicone fillers is challenging, as the hydrophobic material often disperses within the soft tissue as droplets. This can lead to a systemic inflammatory reaction requiring steroid treatment. MRI localization of the filler material does not enable intraoperative guidance, and palpitation of the material is challenging since the filler droplets are often too small to palpate and located in multiple planes. We present a case demonstrating the advantages of utilizing intraoperative ultrasound to localize and silicone filler material. Utilizing this technique, we were able to achieve a high degree of excision of silicone filler material and the patient was able to stop her previous necessary immunosuppressive steroid regimen successfully.
