EXTENSIONS AND COMMENTARY The well appears to be running dry, with a pentane chain as a basic skeleton. METHYL-J, at this level, was already showing a number of hints and clues, largely physical such as coldness in the feet and a slight mastoidal pressure, that activity was right around the corner. But METH YL-K gave no such hints. The unmethylated homologue, 2-amino-1-(3,4-methylenedioxy-phenyl)pentane (K), was also made, by the reductive amination of 1 -(3,4-methylene-... 

Based on their findings, bone sarcomas, carcinomas of the perinasal sinuses and mastoid air cells (often called head cancers), and deterioration of skeletal tissue are considered to be the only effects that are unequivocally attributable to internal radium (Rundo et al. 1986).

Chronic thrombosis or only partially recanalized dural sinus thrombosis may be diagnosed in these patients (Thron et al. 1986 Wessel et al. 1987). This type is less obvious on the static MRI (Isensee et al. 1994) and requires MR venography, if possible in a contrast-enhanced technique. In children, purulent mastoiditis is an important cause of septic thrombosis (Reul et al. 1997) or... 

Hirst first attended a kindergarten school in Burnley, and then had private tutoring in other towns, and a governess in Ipswich where, at the age of 8, he attended Ipswich Municipal Secondary School. The following year, he suffered a sharp set-back due to a severe mastoid illness. In 1910, he was more settled in St. Andrews, where after a considerable personal effort, he succeeded in gaining entrance to the... 

Thrombosis in the dural sinuses or cerebral veins is much less common than cerebral arterial thromboembolism. It causes a variety of clinical syndromes, which often do not resemble stroke (Bousser and Ross Russell 1997). While ischemic arterial stroke and cerebral venous thrombosis share some causes (Southwick et al. 1986), others are specific to cerebral venous thrombosis (Table 29.1). A particularly high index of suspicion is required in women on the oral contraceptive pill (Saadatnia and Tajmirriahi 2007) and in the puerperium. In the past, cerebral venous thrombosis was strongly associated with otitis media and mastoiditis, lateral sinus thrombosis or otitic hydrocephalus, but the most common causes are now pregnancy and the puerperium, which cause 5-20% of the cerebral venous thrombosis in the developed world, the oral contraceptive pill, malignancy, dehydration, inflammatory disorders and hereditary coagulation disorders. No cause is found in around 20% of cases.

Powdered preparations have been used for many years in otology. These were originally applied as dusting powders for chronic otitis and were especially useful for a mastoid cavity. Before the advent of antibiotics, antiseptic and acid powders were insufflated into mastoid cavities. Unlike many other otic preparations, powders do not cause pain on administration. 

A powder insufflator can be used for the instillation of antimicrobial agents into the external ear canal or mastoid cavity. Current antibiotic preparations suitable for the insufflator device are shown in Table 5. They are packaged into capsules that fit into the insufflator. The patient can easily blow the powder into the ear canal without spreading it around. The activity of these anti biotics against organisms responsible for chronic otitis has already been stated. Other common antibiotics or antiseptics may be applied in powder form in an otolaryngologist s office boric acid is the most common example (Fig. 2). 

In addition to the desire for immediate symptom improvement, prevention of mastoiditis and meningitis has been suggested as a reason to prescribe immediate antibiotic treatment for acute otitis media. The rates of mastoiditis in the Netherlands, Norway, and Denmark (all countries in which delayed therapy has been adopted) and those in Canada, the United States, Austraha, and the United Kingdom were compared. The delay of antibiotic use resulted in an increase from about 2 to 4 cases of mastoiditis per 100,000 children per year, accompanied by about 1600 fewer children per 100,000 experiencing antibiotic side effects. Of note, in the Netherlands, only 1.1% of infections caused by S. pneumoniae are penicUhn-resistant. 

Nonsuppurative comphcations such as acute rheumatic fever, acute glomerulonephritis, and reactive arthritis may occur, as well as suppurative complications, such as peritonsillar abcess, retropharyngeal abscess, cervical lymphadenitis, mastoiditis, otitis media, sinusitis, and necrotizing fascutis. 

The goals of treatment of pharyngitis are to improve clinical signs and symptoms, minimize adverse drug reactions, prevent transmission to close contacts, and prevent acute rheumatic fever and suppurative complications, such as peritonsillar abscess, cervical lymphadenitis, and mastoiditis. ... 

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of children and, in this age group, approximately one third of all RMSs occur in the head and neck, particularly involving the orbit, middle ear-mastoid, nasopharynx, and sinonasal tract. Ti jjj contrast, RMS is uncommon in adults, especially in the head and necb. TT tumor does involve... 

Meningiomas occurring outside the cranial cavity (ectopic or extracranial meningiomas) are uncommon. When they do occur, they are usually in the middle ear-mastoid and sinonasal tract-nasopharynx. When found, a primary intracranial meningioma with secondary involvement of the head and neck should be excluded. 

True ectopic meningiomas of the ear-mastoid are more common in females by a ratio of 2 1 and have...
