Multi-axial system

The DSM-IV organizes each psychiatric diagnosis into five levels (axes) relating to different aspects of disorder or disability:
  • Axis I: Clinical disorders, including major mental disorders, and learning disorders
  • Axis II: Personality disorders and mental retardation (although developmental disorders, such as Autism, were coded on Axis II in the previous edition, these disorders are now included on Axis I)
  • Axis III: Acute medical conditions and physical disorders
  • Axis IV: Psychosocial and environmental factors contributing to the disorder
  • Axis V: Global Assessment of Functioning or Children's Global Assessment Scale for children and teens under the age of 18
Common Axis III disorders include brain injuries and other medical/physical disorders which may aggravate existing diseases or present symptoms similar to other disorders.

Lumps in the groin

Lumps in the groin: Differential diagnosis Inguinal hernia, femoral hernia, enlarged lymph nodes, saphena varix, hydrocele of the cord (or of the canal of Neck in women), vaginal hydrocele, undescended testis, lipoma of the cord, femoral aneurysm, psoas abscess. Determining the diagnosis Hernia A hernia (usually) has a cough impulse (i.e. it expands on coughing) and (usually) reduces with direct pressure or on lying down unless, uncommonly, it is incarcerated (i.e. the contents of the hernia are fixed in the hernia sac by their size and by adhesions).  Movement of the lump is not the same as expansion . Many groin lumps have a transmitted impulse on coughing (i.e. they move) but do not expand on coughing.  Since inguinal and femoral hernias arise from within the abdomen and descend into the groin, it is not possible to get above them. For lumps that arise from within the scrotum, the superior edge can be palpated (i.e. it is possible to get above them). Once a

AN UNEXPECTED CHEST XRAY

AN UNEXPECTED CHEST XRAY Mrs MacLeod was a rather prudent 54 year old women, that presented with a shortness of breath, a chronic cough and recurrent pneumonia. She had an obstructive lung pattern on pulmonary function tests. She come in for an xray of the chest. The chest XRAY was rather different. There was unequal lung volumes, with the right lung volume being larger than the left. There was also decreased left lung vessels noted. There were no pleural effusions and no pneumothorax present either. The right lung was perfectly normal. Upon further investigation she reported to have had a significant childhood viral infection that resulted in distal airspace obstruction, probably secondary to an adenovirus or and RSV viral infection. A case of Sweyer-James syndrome was diagnosed. She was treated with influenza vaccinations, but in this case no lobectomy was performed as the no specific lung segment was identified.
