Herpes zoster (HZ) also known as shingles is a common dermatological pathology seen in the emergency department. Multidermatomal involvement is an uncommon presentation and usually is linked to immunocompromised individuals. However, it is rarely reported in the immunocompetent population.

We report a 30-year-old Emirati male complaining of low-grade fever for 3 days, sore throat and an uncomfortable pruritic erythematous rash over his chest and back for 2 days. He was treated the day preceding his presentation in another facility for a presumed allergic reaction after taking ibuprofen. On physical examination, he was found to have exudative tonsillitis and influenza and was treated for both and discharged. He returned to the emergency department reporting increasing pain and was referred to be seen in the dermatology clinic where a biopsy was obtained, and he was discharged with a steroid topical cream. Fourteen days later, he returned to the clinic reporting crusting of the rash; the biopsy results were positive for herpes zoster. The diagnosis of multidermatomal herpes zoster was made, and he was then treated with antivirals.

Herpes zoster can present with atypical manifestations. Multidermatomal HZ is a rare dermatological manifestation in the immunocompetent adult. It is characterised by a rash spread over two or more adjacent dermatomes. This case highlights the challenging diagnosis of this dermatological presentation.

The emergence of metallo-β-lactamase (MBL)-producing isolates is alarming since they carry mobile genetic elements with great ability to spread; therefore, early detection of these isolates, particularly their reservoir, is crucial to prevent their inter- and intra-care setting dissemination and establish suitable antimicrobial therapies. The current study was designed to evaluate the frequency of antimicrobial resistance (AMR), MBL producers and identification of MBL resistance genes in Escherichia coli strains isolated from fecal samples of the healthy children under 3 years old. A total of 412 fecal E. coli isolates were collected from October 2017 to December 2018. The study population included healthy infants and children aged < 3 years who did not exhibit symptoms of any diseases, especially gastrointestinal diseases. E. coli isolates were assessed to determine the pattern of AMR. E. coli isolates were assessed to determine the pattern of AMR, the production of extended spectrum β-lactamase (ESBL) ings showed that children not exposed to antibiotics can be colonized by E. coli isolates resistant to the commonly used antimicrobial compounds and can be a good indicator for the occurrence and prevalence of AMR in the community. These bacteria can act as a potential reservoir of AMR genes including MBL genes of pathogenic bacteria and lead to the dissemination of resistance mechanisms to other bacteria.

Ultrasound-guided fascia iliaca compartment block (US-FICB) is not part of the learning curriculum of the emergency physicians (EP) and is usually performed by anesthesiologists. However, several studies promote EP to use this procedure. The goal of this study was to assess the feasibility of a training concept for non-anesthesiologists for the US-FICB on a simulator based on a validating learning path.

This was a feasibility study. Emergency physicians and medical students received a 1-day training with a learning phase (theoretical and practical skills), followed by an assessment phase. The primary outcome at the assessment phase was the number of attempts before successfully completing the procedure. The secondary outcomes were the success rate at first attempt, the length of procedure (LOP), and the stability of the probe, corresponding to the visualization of the needle tip (and its tracking) throughout the procedure, evaluated on a Likert scale.

A total of 25 participants were included. The median number of attempts was 2.0 for emergency physicians and 2.5 for medical students, and this difference was not significant (p = 0.140). Seven participants (28%) succeeded at the first attempt of the procedure; the difference between emergency physicians and medical students was not significant (37% versus 21%; p = 0.409). The average LOP was 19.7 min with a significant difference between emergency physicians and medical students (p = 0.001). There was no significant difference regarding the stability of the probe between the two groups.

Our 1-day training for non-anesthesiologists with or without previous skills in ultrasound seems to be feasible for learning the US-FICB procedure on a simulator.

Zhengdan 958 (Zheng 58 × Chang 7-2), a commercial hybrid that is produced in a large area in China, is the result of the successful use of the heterotic pattern of Reid × Tang-SPT. The jointing stage of maize is the key period from vegetative to reproductive growth, which determines development at later stages and heterosis to a certain degree. MicroRNAs (miRNAs) play vital roles in the regulation of plant development, but how they function in the sixth leaf at the six-leaf (V6) stage to influence jointing stage heterosis is still unclear.

Our objective was to study miRNAs in four hybrid combinations developed in accordance with the Reid × Tang-SPT pattern, Zhengdan 958, Anyu 5 (Ye 478 × Chang 7-2), Ye 478 × Huangzaosi, Zheng 58 × Huangzaosi, and their parental inbred lines to explore the mechanism related to heterosis. A total of 234 miRNAs were identified in the sixth leaf at the V6 stage, and 85 miRNAs were differentially expressed between the hybrid combinations and their parental inbred lines. CAL-101 cell line Most of the differentially expressed miRNAs were non-additively expressed, which indicates that miRNAs may participate in heterosis at the jointing stage.
