The consequence of darling upon post-tonsillectomy pain relief: any randomized clinical trial.
44 ng mL-1. In addition, polyaldehyde-dextran showed priority over polycarboxylated-dextran as the multivalent antibody crosslinker for MNPs in terms of sensitivity and LOD value, while immunosensors constructed with carboxylated magnetic microbeads (HOOC-MBs) outperformed MNPs-based immunoplatforms. This work sheds light on the importance of surface chemistry (type and density of functional groups) and the dimension (nanosize vs micrometer) of magnetic carriers to conjugate antibodies with better directional orientation and improve the analytical performance of the resulting immunosensors.In this work we present a powerful, affordable, and portable biosensor to develop Point of care (POC) SARS-CoV-2 virus detection. It is constructed from a fast, low cost, portable and electronically automatized potentiostat that controls the potential applied to a disposable screen-printed electrochemical platform and the current response. The potentiostat was designed to get the best signal-to-noise ratio, a very simple user interface offering the possibility to be used by any device (computer, mobile phone or tablet), to have a small and portable size, and a cheap manufacturing cost. Furthermore, the device includes as main components, a data acquisition board, a controller board and a hybridization chamber with a final size of 10 × 8 × 4 cm. The device has been tested by detecting specific SARS-CoV-2 virus sequences, reaching a detection limit of 22.1 fM. Results agree well with those obtained using a conventional potentiostat, which validate the device and pave the way to the development of POC biosensors. In this sense, the device has finally applied to directly detect the presence of the virus in nasopharyngeal samples of COVID-19 patients and results confirm its utility for the rapid detection infected samples avoiding any amplification process.As one of the earliest miRNAs discovered in the human genome, miRNA-21 can provide vital information for the early diagnosis, drug treatment, and prognosis of cancers. Herein, we construct a fast, time-saving fluorescence detection system for miRNA-21 detection by coalescing the improved endonuclease-mediated rolling circle amplification with catalytic hairpin assembly (RCA-NESA-CHA). Firstly, the target miRNA cyclized the padlock, initiating rolling circle amplification (RCA) and extending a long-concatenated DNA. The modified Protector bonded with the long-strand DNA to generate an endonuclease-specific site and trigger the nicking process. Finally, DNA products with repetitive sequences not only recombined with the padlock to reactivate a new recycle of RCA but also triggered the catalytic hairpin assembly to form the H1-H2 complex, realizing the cooperative amplification of the signal. In this system, RCA-NESA and CHA were integrated into one step, which essentially simplifies the sensing process. Moreover, the introduction of the Protector would inhibit the extension reaction caused by the combination of the padlock and the RCA products, slowing down the non-specific reaction time and improving the sensitivity of the fluorescence detection system. Under the optimal experimental conditions, the fluorescence system achieved a limit-of-detection of 0.025 amol miR-21 in a 40 μL sample and successfully applied to miR-21 detection in serum samples from breast cancer patients, showing good agreement with the results of RT-PCR, which exhibited great potential in biomedical research and clinical diagnosis.
We present the case in which a large symptomatic pseudoaneurysm (PSA), 6×5cm, with one year of evolution on the path of the right radial artery (RRA) appeared after its punction and cannulation for performing cardiac catheterism in an atrial fibrillation (AF) indefinite anticoagulated patient. Diagnosis and surgical planning were consolidated only by using color duplex ultrasound (CDU), contrasted images were not indicated. The open surgical management was performed during a short-time supraclavicular blockade of peripheral nerves without stopping nor bridging anticoagulant therapy. Complete excision of the deforming mass with no blood loss, decompression of the adjacent structures and direct closure of the arterial defect without compromising of its lumen and path were also achieved.

A 74-year-old, Hispanic male patient and former smoker underwent coronary catheterization for thoracic typical pain. One year after, he is admitted for move restrictive pain in distal right forearm and hand paresthesia relat nor sequelae. Since the number of AF patients is increasing worldwide, main aspects on anticoagulation therapy have to be taught to every surgical team.
Ileo-sigmoid knotting is a very rare cause of bowel obstruction. The diagnosis can be challenging and may not be suspected pre-operatively. A high index of suspicion, especially in areas of the "sigmoid belt" region, can be helpful.

A 40-year-old ethnic Amhara female patient presented with symptoms and signs of bowel obstruction. She presented in shock and after resuscitation, laparotomy revealed gangrenous ileum twisted around the sigmoid colon ('ileo-sigmoid knotting'). The gangrenous ileal segment was resected, with end-to-end ileo-ileal anastomosis. check details The patient had a smooth postoperative course and was discharged on the 4th post-operative day.

Twisting of the ileum around the sigmoid colon is pathognomonic of ileo-sigmoid knotting. Prompt resuscitation and surgical intervention in the shocked patient with an acute abdomen and evidence of intestinal obstruction could be life-saving.

Caustic agents, also called corrosive agents, could be acids or alkali in nature. If ingested, these agents can injure any part of the aerodigestive tree. Extent of injury depends on the type, concentration, duration of exposure and volume of caustic agent ingested. Serious complications after caustic agent ingestion can occur both in the short term such as hollow viscus perforation and death and in the long term such as stricture formation causing obstruction and lifetime risk of development of carcinoma.

This is a case of a 25-year-old female who ingested an unknown substance resulting to a severe stricture of the larynx, hypopharynx, esophagus and pyloroantral region of the stomach. Six months after her tracheostomy and tube jejunostomy, she sought further medical attention in our institution due to inability to swallow food and saliva. She underwent pharyngolaryngectomy (PL) with the strictured esophagus and stomach left in-situ due to extensive adhesions. The subcutaneous colonic interposition reestablished the alimentary continuity by providing enough length for tension-free anastomosis and a more direct route for cervical anastomosis.

Stricture formation is one of the most challenging late complication of corrosive injury. It results from scar formation in response to inflammation of the aerodigestive tract. Key factors in managing caustic strictures include safety of strictured segment resection, choice of replacement organ for reconstruction and route of conduit.

Timing of surgery and proper selection the surgical procedure for complications of caustic ingestion can result in excellent long term outcomes.

Osteoarticular tuberculosis represents 1 to 3% of all tuberculosis cases, the tuberculosis of the talus is a very rare form of osteoarticular tuberculosis. Its clinical and radiological features are not specific. In this study, we report a case of ankle tuberculosis involving the talus in a 5-year-old girl.

A 5years old girl, was admitted for pain, swelling, and functional impairment of the left ankle, on the clinical examination, the patient manifested a painful oedematous ankle. The biological examination revealed a slight inflammatory syndrome, The X-ray of the ankle showed a lytic image of the posterior part of the talus with a cortical involvement. The biopsy revealed an epithelioid cell granuloma without any caseous necrosis. The medical management consisted of anti-tuberculosis multi-drug.

The tuberculosis of the talus is a very rare form of osteoarticular tuberculosis. In this study, we report a rare case of this localization of a 5-year-old girl. The non-specificity of symptoms is the main difficulty that causes a delay in diagnosis. Standard radiology, MRI, and biology were non-contributory. Bone biopsy and anatomopathological study led to the diagnosis of tuberculosis of the talus. The main aims of the surgical treatment are to take some sample for histological study, and to curette the diseased part in the bone followed by 6 to 9months of anti-tuberculosis chemotherapy.

Tuberculosis of the talus is extremely rare, it deserves special attention especially in endemic areas.

Situs inversus totalis (SIT) is a congenital anatomical variant in which organs and vasculature are positioned in a mirror-image relationship to the normal condition. Therefore, the surgical procedures need to be carefully planned with these factors in mind.

A 57-year-old man with SIT was diagnosed with a hepatocellular carcinoma (HCC) and was planned for caudate lobectomy. As preoperative preparation, 3D reconstructed images were created based on the contrast-enhanced CT images, and careful simulations were performed on the vascular anomalies and location of the tumor. There was a replaced left hepatic artery forming a common trunk with a left gastric artery. In addition, using media player software, a previous caudate lobectomy video was played in right and left inverted mode to simulate the abdominal surgical field image in SIT. The operative time was 285min, and the blood loss was 440ml. The preoperative careful simulation allowed us to proceed with the surgery without significant discomfort.

Even in the case of hepatocellular carcinoma with SIT, hepatectomy for hepatocellular carcinoma can be safely performed by careful preoperative simulations.

Ectopic pregnancies are a dreaded and common cause of first-trimester metrorrhagia. They refer to the implantation and development of the embryo outside the uterine cavity. Interstitial localization is uncommon and corresponds to implantation of the embryo in the intramural part of the uterine tube. It has an unforeseen evolution with a risk of cataclysmic hemorrhage by uterine rupture in the absence of early diagnosis and management.

We herein present the uncommon case of a 26-year-old female patient, second gestation, nulliparous, who underwent a pelvic ultrasonography in the emergency department for pelvic pain associated with a two-month amenorrhea. A past history of left salpingectomy for a ruptured tubal ectopic pregnancy 3years ago was found. Pelvic ultrasound allowed us to detect a ruptured ectopic interstitial pregnancy at 7weeks of amenorrhea. Significant hemoperitoneum and hemodynamic instability required emergency laparotomy. The condition was confirmed preoperatively and the patient underwent a corneal resection.
