38. Peptic ulcer of the esophagus
Peptic ulcer of the esophagus is an acute or chronic disease characterized by ulceration of the mucosa of the distal segment of the esophagus under the influence of active gastric juice.
Etiology and pathogenesis. Chronic peptic ulcers of the esophagus are complications of reflux esophagitis and hiatal hernia. Their occurrence is facilitated by the internal short esophagus, focal metaplasia of the mucosa, heterotopia of the gastric mucosa into the esophagus, reflux disease with cardia insufficiency, diseases accompanied by frequent vomiting (post-vagotomy syndrome, afferent loop syndrome, chronic alcoholism).
Clinical picture. Symptoms of a peptic ulcer of the esophagus resemble the clinical picture of peptic esophagitis: persistent heartburn, worsening after eating, when bending the body, in a lying position, regurgitation, pain when swallowing, and impaired passage of solid food occur.
The clinical symptoms of perforation are indistinguishable from the symptoms of acute penetrating and non-penetrating mechanical injury by foreign bodies. Approximately 14% of esophageal ulcers penetrate into the surrounding tissues.
Diagnosis and differential diagnosis.
Based on clinical symptoms, it is extremely difficult to suspect a peptic ulcer. The diagnosis is verified in the course of instrumental and laboratory research. The most informative X-ray and endoscopic examination.
The most reliable information in the verification of peptic ulcer of the esophagus is provided by endoscopy and multiple biopsy from the edges of the ulcer. When advancing the endoscope to the peptic ulcer, signs of stage I-IV esophagitis, motor dysfunction of the esophagus, perifocal edema and hyperemia of the mucous membrane are revealed.
It is necessary to differentiate peptic ulcers of the esophagus with ulcerations of a specific nature (with tuberculosis, syphilis). In these situations, specific serological tests, the results of histological and bacteriological studies significantly help. The combination of the pathology of the esophagus with damage to the lungs and other organs makes it necessary to purposefully examine the patient in relation to a specific process.
Treatment. Treatment includes the appointment of a diet: mechanically and chemically sparing food is recommended, which is taken in small portions 5-6 times a day. To prevent reflux of contents from the stomach into the esophagus, the position of the patient in bed should be with a raised headboard. Medicines are taken lying down. Assign monotherapy with a drug of one of the following pharmacological groups: antisecretory, including antacids and adsorbents, stimulants of the motor-evacuation function of the stomach (prokinetics), drugs - mucus simulators. Therapy is carried out for a long time - 1,5-3 months.
Indications for surgical treatment - lack of healing within 6-9 months, complicated course (perforation, penetration, stenosis, bleeding).
Forecast and prevention. The prognosis for life and work is favorable.

The existence of an entropy rule for quantum entanglement has been proven
09.05.2024
Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Random news from the Archive BlueNRG-1 is a new single-chip Bluetooth Low Energy solution
31.07.2016
The BlueNRG-1 system-on-chip from STMicroelectronics allows you to create a complete device based on a single chip with support for Bluetooh Low Energy technology. The chip is extremely low power and offers 100kB of Flash memory for a user application that runs on a low power Cortex-M0 core.
The BlueNRG-1 is designed for the growing Bluetooth low energy markets, including retail, wearables, smart home devices, and automotive, industrial, and medical applications. Support for the latest Bluetooth Low Energy specification ver 4.2 ensures advanced data security and privacy.
The BlueNRG-1's ability to quickly transition between power-saving and active modes extends battery life from months to years. In addition, the output power of the chip has been increased to +8dBm to ensure clear and reliable communication even in the presence of a lot of interference in the 2,4GHz band.
New BlueNRG-1 features include a dedicated digital microphone input that simplifies voice application support and operation in temperatures up to 105°C, which is critical for applications such as smart lighting and automotive electronics. The BlueNRG-1 will be available in two package types - 5mm x 5mm QFN-32 (BlueNRG-132) and 2,7mm x 2,6mm WLCSP-34 (BlueNRG-134).
BlueNRG-1 Features:
System-on-a-chip 32MHz ARM Cortex-M0 SoC;
Memory: 160 kB Flash and 24 kB RAM;
Work in Master and Slave modes;
Radio link budget up to 96 dB;
Accurate RSSI readings for power management;
Quick wake up and go to sleep;
Balun to reduce the number of LC components;
10-bit ADC, SPI, 2 x I2C, UART, and up to 15 GPIOs;
Built-in DC/DC buck converter;
Maximum current consumption 8,2 mA (@ 0 dBm, 3.0 V);
Current 1uA in sleep mode (active BLE stack);
Operating voltage from 1,7 to 3,6 V.
Bluetooth Low Energy technology is ideal for battery smart sensors, indoor positioning beacons, keyless entry systems, remote controls and vehicle trackers. Shipments of Bluetooth Low Energy IoT products are expected to increase by 34% by 2021 to reach 1,4 billion units (according to ABI Research).
The penetration of BLE technology for the Internet of Things is facilitated by the widespread use of BLE-enabled tablets and smartphones, which provide a convenient user interface for interacting with Bluetooth low energy devices.
