Congenital diaphragmatic hernia (CDH) is a birth defect of the diaphragm. The most common type of CDH is a Bochdalek hernia;  other types include Morgagni hernia, diaphragm eventration and central tendon defects of the diaphragm. Malformation of the diaphragm allows the abdominal organs to push into the chest cavity, hindering proper lung formation.CDH is a life-threatening pathology in infants and a major cause of death due to two complications: pulmonary hypoplasia and pulmonary hypertension. Experts disagree on the relative importance of these two conditions, with some focusing on hypoplasia, others on hypertension. Newborns with CDH often have severe respiratory distress which can be life-threatening unless treated appropriately. Classification
Bochdalek hernia
The Bochdalek hernia, also known as a postero-lateral diaphragmatic hernia, is the most common manifestation of CDH, accounting for more than 95% of cases. In this instance the diaphragm abnormality is characterized by a hole in the postero-lateral corner of the diaphragm which allows passage of the abdominal viscera into the chest cavity. The majority of Bochdalek hernias (80–85%) occur on the left side of the diaphragm, a large proportion of the remaining cases occur on the right side. To date, it carries a high mortality and is an active area of clinical research. Morgagni hernia
This rare anterior defect of the diaphragm is variably referred to as a Morgagni, retrosternal, or parasternal hernia. Accounting for approximately 2% of all CDH cases, it is characterized by herniation through the foramina of Morgagni which are located immediately adjacent and posterior to the xiphoid process of the sternum.
The following were conditions under the term Somatoform Disorders:

Conversion disorder: A somatic symptom disorder involving the actual loss of bodily function such as blindness, paralysis, and numbness due to excessive anxiety
Somatization disorder
Hypochondriasis
Body dysmorphic disorder: wherein the individual is concerned with body image, and the disorder is manifested as excessive concern about and preoccupation with a perceived defect of their physical appearance. Pain disorder
Undifferentiated somatic symptom disorder – only one unexplained symptom is required for at least six months.In the newest version of DSM-5 (2013) somatic symptom disorders are recognized under the term somatic symptom and related disorders:

Somatic symptom disorder: To replace many of what was formerly known as somatization disorders and hypochondriasis (hypochondria). Factitious disorder: Can be either imposed on oneself, or to someone else (formally known as factitious disorder by proxy). Illness anxiety disorder: A somatic symptom disorder involving persistent and excessive worry about developing a serious illness. This disorder has recently gone under review and has been altered into three different classifications. Somatoform disorder not otherwise specified (NOS)Included among these disorders are false pregnancy, psychogenic urinary retention, and mass psychogenic illness (so-called mass hysteria). Somatization disorder as a mental disorder was recognized in the DSM-IV-TR classification system, but in the latest version DSM-5, it was combined with undifferentiated somatoform disorder to become somatic symptom disorder, a diagnosis which no longer requires a specific number of somatic symptoms.
