要旨

Objective:

To describe a modified surgical technique for treating pectus excavatum (PE) in small animals and report the outcomes by evaluating preoperative and postoperative lung and total chest volumes, as well as complications and short-term outcomes.

Methods:

Owned pets between 8 and 20 weeks of age with PE were enrolled in the study between February 28, 2024, and September 26, 2025. Preoperative evaluation included thoracic radiographs, baseline blood work, and whole-body CT scans. A noncontoured bone plate was secured along the entire length of the sternum with multiple cerclage wires. Animals had physical examinations and imaging performed at 2 and 8 weeks postoperatively, and again when they were between 8 and 12 months of age.

Results:

This study included 6 cats and 1 dog, all of which recovered successfully from surgery. Lung and chest volumes improved immediately after surgery. Pectus excavatum was corrected in all animals. At the final recheck, 2 cats had reduced lung volume compared to immediately after surgery along with new pulmonary pathology; however, the total chest volume increased in these cats. Complications observed in this study included pneumothorax in 1 cat, fracture of the eighth sternebrae in 1 cat, and cerclage wire breakage in another cat, which had no clinical impact.

Conclusions:

The use of internal plate and cerclage wires to correct PE was a simple, well-tolerated technique that improved lung and chest volumes and had minimal complications.

Clinical Relevance:

Internal plating could be used for correction of PE in young cats and dogs.

Distance Corrections

Distance Corrections

To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

Internal Energy

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Power Factor Correction

Power Factor Correction

The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

Internal Receptors

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Hemodialysis II: Procedure and Complications

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Fixation and Sectioning

Fixation and Sectioning

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
