We are glad Mrs Gardner is well again. Mrs Ayton has had another fortnight s serious illness, but is now recovering. I am up to my head and ears in a pool of mixed Parochial, Saecular, and Occult work and do not know which way to turn. 

Personal protective equipment is designed to protect an individual when faced with a particular hazardous situation. Accordingly, one must determine the need for such equipment, the type to be used, and the conditions under which it must be worn. For simplicity, we will consider protection under four categories respiratory system face and eyes head and ears body and limbs. 

Breathing zone The space around an operator in which breathing occurs, normally taken as being a hemisphere of radius 0.3 m circumscribing the ears, the top of the head and the larynx. 

If one is patient, the blood flow will start. However, where no flow occurs, then one needs to resort to the bottom of the lobe of the ear, because while the blood flow may be restricted to the extremities in certain severe conditions, the flow to the head and the brain is not, and one can usually get an adequate amount of capillary blood from the ear. Once the blood...

In all patients and ages BPPV can also be an effect of damage to the peripheral vestibular system by a head trauma, ear infection or ototoxicity. Ototoxity can be a result of different drugs or chemicals in the surrounding environment. 

In describing his voyage to northern Virginia with Sir Walter Raleigh, John Brereton wrote in 1602 that he had seen Indians wearing elaborate chains, earrings, and collars of copper, and that some of their arrow heads and skull-shaped drinking cups were made of it (44). 

Ninety percent of victims claimed that sulfuric acid was the chemical involved [24]. Injured areas were confined to the head and neck. While most had their faces flushed with tap water, none had continuous effective flushing, especially of the eyes, before presentation to hospital. Most had half or more of then faces grossly disfigured by scars. Six patients (40%) had total bilateral blindness and one had partial loss of vision. Other common function sequelae were lower eyelid ectropion (14/15), microstomia (12/15), cervical flexion contracture (10/15), ear deformity (8/15), and nostril stenosis (6/15). Victims had severe psychological and social effects, and most lived as recluses. 

A major type of headache that must be considered in differential diagnosis is that caused by underlying disease intracranial disturbances (e.g., vascular anomalies, infections, tumors, trauma) diseases involving the head and neck but not the brain (e.g., cervical osteoarthritis disorders of eye, ear, nose, sinuses, and throat cranial neuralgias) and systemic diseases (e.g., sudden and severe hypertension, hyperthyroidism). These headaches usually can be relieved by specific therapy for the underlying disorder (e.g., surgical correction of tumors, antibiotics for infections, antiarthritic drugs for osteoarthritis). 

The ear bars can also be inserted into the ear canals to hold the head in place. However, it is very easy to puncture the tympanum or to apply too much pressure and cause breathing difficulties. The head must be securely fixed in place using the nose clamp and ear bars. If the head moves during leveling or drilling, it will affect stereotaxic accuracy.

The patient should remain with head down and ear uppermost for at least 5 minutes to allow for absorption. 

The most common use of personal protective equipment is for the protection of head, eyes, ears, torso, hands, and feet. This equipment helps to protect a person from damage normally encountered in an industrial plant, a construction site, or land renovation project. PPE includes devices and clothing designed to be worn or used for the protection or safety of an individual in potentially hazardous areas or performing potentially hazardous operations.
