DESCENT OF THE TESTIS

The early genital ridge on the posterior wall of the coelomic cavity contains the primordial testis and extends from the sixth thoracic to the second sacral segment. At 8 weeks’ gestation, the testis, lying beneath the mesothelium (primitive peritoneum), becomes an elongated, spindle-shaped organ projecting into the coelomic cavity (future abdominal cavity).

DERMATOFIBROMA (SCLEROSING HEMANGIOMA)

Dermatofibromas are among the most common types of benign skin growths. Usually, they occur on the extremities, with a predilection for the legs. There is some debate as to whether this is a true neoplasm or an inflammatory reaction.

BECKER’S NEVUS (SMOOTH MUSCLE HAMARTOMA)

Becker’s nevi most commonly appear on the shoulder or upper limb girdle of prepubescent boys. It is a rather common benign condition that is seen in up to 0.5% of the male population. It is less commonly seen in females. Becker’s nevi are acquired nevi. Most occur before 10 years of age. Becker’s nevus is classified as a smooth muscle hamartoma. It does not contain melanocytic nevus cells and is not considered to be a melanocytic nevus. It was given its name by the dermatologist Samuel Becker, who first described this condition.

ACROCHORDON

Acrochordons are better known by their common name of skin tag or fibroepithelial polyp. They are found universally throughout humankind. Probably every adult has at least one skin tag located somewhere across the surface of his or her skin. Except for a few loose associations with certain syndromes, skin tags have no clinical importance and are often ignored.

Endotracheal Intubation: Procedure, Equipment, Tube Size, and Placement

ENDOTRACHEAL INTUBATION

Endotracheal intubation is a lifesaving procedure that requires familiarity with anatomy, physiology, pharmacology, and the necessary equipment required to perform the procedure.

Choice of the correct size of endotracheal tube is fundamental. The average man will accept a cuffed tube with an inner diameter of 8.0 or 8.5 mm. For women, the tube diameter is 0.5 to 1.0 mm smaller. Smaller tubes have more resistance to airflow and may not allow passage of a bronchoscope, but larger tubes may increase injury to the glottis and lower airway.

EJACULATORY DISORDERS

Although commonly viewed as a single event, ejaculation is actually two separate processes, termed emission and ejaculation. During emission, the semen is “loaded” into the prostatic urethral chamber. After this, ejaculation is the forcible expulsion of semen from the penis in a series of spurts caused by rhythmic contractions, about 1 second apart, of the pelvic muscles. Ejaculation is different from orgasm or climax, the latter being an event that is centered in the brain that is closely associated with ejaculation.
