Outlook Most people are familiar with left-sided chest pain and how it can indicate serious heart problems, such as a heart attack or other heart diseases. Right-sided chest pain is not usually talked about as often, but can still indicate a variety of problems. Pain in the right side of the chest can result from direct injury or inflammation of certain structures, or by referred pain. Referred pain is when pain originates in a different part of the body.

Abstract The purpose of this review is to illustrate the wide spectrum of lesions in the corpus callosum, both congenital and acquired: Introduction Corpus callosum is one of the three interhemispheric commissures anterior commissure, hippocampal commissure and corpus callosum and the greatest of them—it consists of approximately axons [ 1 ].
Its role is interhemispheric connection and coordination. A good example of this role is an alien hand syndrome AHS: The callosal type of AHS can best be explained by the loss of interhemispheric connection, revealed during activities that require control of the dominant hemisphere [ 2 ].
Another example is the role of the corpus callosum in the interhemispheric spread of epileptic activity and the efficacy of corpus callosotomy in cases of medically intractable epilepsy [ 3 ].
Transection of the anterior part of the callosal body during neurosurgical procedures aiming at the removal of tumors of the third or lateral ventricles leads to the deficits of memory, the dysexecutive cognitive and behavioral syndrome, disturbances in interhemispheric transfer of learning from one hand to the other, and an increase in reaction times [ 4 ].
In the anterior-posterior direction the corpus callosum is divided into rostrum, genu, body, isthmus, and splenium. The fibers in the rostrum connect fronto-basal cortex, in the genu—prefrontal cortex and anterior cingulate area, in the body—precentral motor cortex, insula, and cingulate gyri, in the isthmus—precentral and postcentral gyri motor, somatosensory and primary auditory areas, and in the splenium—posterior parietal, medial occipital, and medial temporal cortexes [ 5 ].
According to the newest theory the corpus callosum in its embryological development is fused of two separate parts: The place of the fusion is the isthmus. Callosal development is a very quick process and takes place in 13th week of gestational life.
From this time on the corpus callosum grows mainly in the anterior direction, pushing the splenium posteriorly.
It reaches its final shape in midgestation week 20 but is still small and grows, initially by addition of fibers and later by myelination [ 5 ]. The target volume is reached at the age of 6—9 years. Myelination of the brain progresses from the center to the periphery, from bottom to top and from back to front.
In newborns corpus callosum is not yet myelinated. In the 6th month after birth, when the cerebellum and genu of the internal capsule completed the process of myelination, the corpus callosum is myelinated in part spleniumalthough it has not yet reached its target volume.
Callosal genu is myelinated a little bit later than splenium—in about 8th month.
It is not until about the first year of life that the corpus callosum displays the typical signal intensity: There are a few papers illustrating callosal pathology in the literature [ 6 — 8 ].
Continuing our work from the past [ 9 ] we present a more detailed review of congenital and acquired callosal changes in fetuses, children, and adults with rich iconography from the own archive. Acquisition Parameters of Presented Images All the images were acquired with 1.
Figures 418202223282930and 34 in adult patients were acquired with one GE Signa HDxt scanner in the years — and the remaining figures in children were acquired with another GE Signa HDxt scanner in the years — The following acquisition parameters were used: TR ms, TE Agenesis and Hypoplasia Incomplete or abnormal development leads to the most common pathology, which affects the organs in question: The characteristic appearance of callosal agenesis makes this anomaly easily and early recognizable on prenatal ultrasound and MRI:In the United States, fire and hot liquids are the most common causes of burns.
Of house fires that result in death, smoking causes 25% and heating devices cause 22%. Almost half of injuries are due to efforts to fight a fire. Scalding is caused by hot liquids or gases and most commonly occurs from exposure to hot drinks, high temperature tap water in baths or showers, hot cooking oil, or steam.
ACL/PCL Injuries RICE is also applied for ACL/PCL injuries if the tears are not severe. To help reduce pain, NSAID can be given to the patient. If the damage is severe, . Cyberfriends: The help you're looking for is probably here.

The first description of ARF, then termed ischuria renalis, was by William Heberden in At the beginning of the twentieth century, ARF, then named Acute Bright’s disease, was well described in William Osler’s Textbook for Medicine (), as a consequence of toxic agents, pregnancy, burns, trauma, or operations on the kidneys.
