17. Pathological processes of the orbit

The main symptom of most diseases of the orbit, both inflammatory and non-inflammatory, is exophthalmos, along with which other symptoms can be noted. The eyeball, depending on the localization of the process in the orbit, can be displaced in one direction or another, its mobility can be limited, diplopia occurs. Sometimes there are changes in the condition of the edges and walls of the orbit. In the presence of dense tissue in the retrobulbar space, the reposition of the eyeball is difficult. In inflammatory diseases of the orbit, eyelids are often involved in the process, possibly a serious general condition of the patient.

In children of any age, but more often in the first year of life and at school age, among full health, eyelid edema suddenly and quickly appears, sometimes significant, chemosis is possible. Exophthalmos develops rapidly, but there may also be a shift of the eyeball to the side (with ethmoiditis, periostitis). The mobility of the eyeball, as a rule, is limited due to a mechanical obstacle, damage to the muscles and motor nerves. There is a severe general condition, high fever, headaches and pain in the orbit.

In infants, general symptoms of the disease often prevail over local ones. In children of the first months of life, except for exophthalmos, it is not possible to identify other signs of the disease. A carefully collected history, consultations of an otolaryngologist, a dentist, and radiography of the paranasal sinuses contribute to the establishment of its cause. In infants, orbital phlegmon is more often associated with inflammatory processes in the upper jaw, umbilical sepsis and dacryocystitis, in schoolchildren with orbital injuries and sinusitis.

Treatment. Loading doses of broad-spectrum antibiotics intramuscularly, periorbitally and retrobulbarno.

If necessary, the cells of the ethmoid labyrinth are opened, the maxillary sinus is punctured. At the same time, the phlegmon of the orbit is opened with drainage of the wound cavity with turunda soaked in antibiotics.

Examination of a patient with sarcoma reveals exophthalmos, displacement of the eyeball, limitation of its mobility, diplopia, a painless tumor-like elastic formation, sometimes soldered to the underlying tissues and skin, is palpated. More often the tumor is localized in the upper half of the orbit. The diagnosis becomes even more likely when indicating the rapid growth (weeks and months) of the tumor.

Orbital sarcoma should be differentiated from eosinophilic granuloma, tumor-like forms of leukemia. To clarify the diagnosis, it is necessary: radiography of the orbits, sternal puncture (study of the myelogram), often puncture biopsy.

Treatment consists of exenteration of the orbit followed by x-ray and chemotherapy.

In some types of leukemia (hemocytoblastosis, etc.), tumor-like infiltration nodes appear on the upper or, less often, lower edge of the orbit, developing from the hematopoietic tissue of the flat bones of the orbit, called lymphomas. Exophthalmos, displacement of the eyeball are noted.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

U.S. renewable power plants surpass coal-fired power 20.06.2019

In April, renewable energy plants outperformed coal-fired power plants for the first time in April, according to a report from the US Federal Energy Regulatory Commission (FERC). This means that they can now produce more clean energy, which is getting cheaper.

In 2016, coal lost its status as the king of the US energy industry in large part due to the so-called shale gas boom. A lot of cheap natural gas appeared in the states, which was used for energy purposes. In April this year, the total generating capacity of coal-based power plants amounted to 257,48 GW. The total installed capacity of renewable electricity, including sunlight, water flows, wind and geothermal heat, reached 257,53 GW.

Thus, the share of power plants based on renewable energy sources amounted to 21,56%, while the share of coal-fired power plants decreased from 23,04% to 21,55%. The difference is insignificant, but the fact itself is important, which suggests that this gap will increase in the coming months. The FERC report also notes that the share of green energy in the US is growing at an average of 1% annually, so by 2022 it will account for almost a quarter of all installed capacity in the states.

Meanwhile, American appetite for coal continues to decline. Since its peak in 2008, US coal consumption has hit its lowest level in 40 years, according to the US Energy Information Administration.
