Strauss Department of Dermatology, University of Iowa, Iowa City, Iowa, USA The acne symposium held at the 20th World Congress in Paris in July 2002 was an opportunity for some of those working in the field to present their findings on a wide selection of topics related to the pathogenesis and treat- ment of acne. The presentations were indeed world-wide, including investigators from Argentina, Chile, France, Germany, Japan, Taiwan, United Kingdom, United States, and Venezuela. As is appropriate for the World Congress which is held every 5 years, these papers are a comprehensive review of the past, present, and future. The publication of these nine papers as a unit in this jour- nal covers varying points of view, and is an excellent refer- ence source for all those interested in acne. There is a need to focus our attention on acne, as it should not be forgot- ten that in developed countries, it is still responsible for more visits to the dermatologist than any other skin dis- ease. A basic theme that runs throughout the nine papers is the importance of the four principles of treating acne, pro- posed many years ago by Kligman and myself. These include correcting the altered pattern of keratinization, the inhibition of Propionibacterium acnes and the produc- tion of extra-cellular pro-inflammatory products, the inhi- I will not comment on all the aspects of these papers, bition of sebum, and producing an anti-inflammatory nor can I predict the future with any certainty. Almost all of the therapeutic approaches summa- less, I want to emphasize three points. First of all, we must rized in the presentations are related to these principles, now reassess antibiotic care for acne. Antibiotics have and as is often mentioned, while we have made tremen- been a cornerstone of our care, as pointed out by Eady and dous strides and are eminently successful in the manage- co-authors. The manage- tance to the macrolides, and to a lesser degree the tetracy- ment of acne will change in the future, and indications of clines, has to dictate changes in our practice.

Neurology 43: 2342– 2345 383 Becker muscular dystrophy (BMD) Genetic testing NCV/EMG Laboratory Imaging Biopsy +++ ++ – + +++ BMD affects proximal greater than distal muscles. Worse in the quadriceps and Distribution hamstrings. BMD is a progressive disorder with a slower rate of progression than DMD. Time course BMD is much milder than DMD with later clinical onset. Patients may have Onset/age difficulty walking by their late teens. Weakness is present in Clinical syndrome approximately 20% of affected patients. In general the severity and onset age correlate with muscle dystrophin levels. As with DMD, affected subjects may have calf muscle hypertrophy and contrac- tures in the lower extremities. Patients with BMD often have a severe cardio- myopathy as part of the muscle weakness syndrome, or may have an isolated dilated cardiomyopathy. In general the average IQ of affected children is re- duced compared to the general population and may be a major presenting symptom in BMD. Some patients may present with an atypical neuromuscular disorder mimicking SMA, a focal myopathy, or a limb girdle muscular dystrophy. Most are exonic or multiexonic (70–80%), although duplications can occur in Pathogenesis 10%, and missense mutations in < 10%. Although dystrophoglycan is reduced in BMD, the molecular abnormality is unknown although it is likely similar to DMD.
PGA of high molecular weight (20 buy generic amantadine 100mg on line, 000 to 145 order amantadine 100 mg overnight delivery, 000) is a hard order amantadine 100 mg, tough, crystalline polymer melting at about 224–228 C, with a glass transition temperature (Tg) of 36 C. PGA can be spun into fibers which increase the strength properties of the polymer because of higher preferred molecular orientation of the polymer in the fiber [46,61]. The other important polymer used in manufacturing surgical devices is the polymer of lactic ( -hydroxycarboxylic) acid. The polymer is called polylactic acid or polylactide (because of synthesis from the dimer of lactic acid, the lactide). PLA has two enantiomeric isomers, the L and the D isomers. PLLA is a crystalline polymer with a prolonged degradation time. Addition of the D isomer into the PLA polymer chain makes it more amorphous, with faster degradation. Various degradation rates of the copolymer can be achieved by changing the percentages of L and D components. PLA with plastic properties was introduced as early as 1955. Later, surgical applications of materials made of either poly-L/D-lactide (PDLA) or poly-L-lactide (PLLA) were tested in the 1960s and 1970s [56,63]. PLLA was initially more commonly used 172 Ashammakhi et al. PLLA has a melting point of about 174–184 C and a glass transition temperature of about 57 C, and it can be spun to form fibers when its average molecular weight is 20,000 to 145,000. After 32–40 weeks, the fracture sites were indistinguishable from the adjacent bone.
Symptoms Mercury metal vapor causes subacute generic amantadine 100 mg with visa, diffuse purchase amantadine 100 mg overnight delivery, predominantly motor neuropa- thy that may mimic AIDP generic amantadine 100 mg mastercard. Alkyl mercury causes intense distal limb paresthesias, probably from CNS dysfunction. Elemental mercury may cause sensorimotor neuropathy. Prognosis Degree of CNS recovery determines prognosis.

Anatomy/distribution Three temporal varieties of neuropathy occur. A massive dose causes acute Symptoms painful neuropathy with GI distress. May resemble AIDP, and proceed to lethargy, coma, and death. A one week or longer exposure at lesser doses causes neuropathy with alope- cia, hyperkeratosis, Mee’s lines, ataxia, chorea, CNS palsies, autonomic dys- function with tachycardia. Chronic exposure at low levels causes extrapyramidal dysfunction and ques- tionable sensorimotor neuropathy. Thallium is found in rodenticides and insecticides, and may be ingested in Pathogenesis situations of homicide and suicide. Diagnosis made by detection of thallium in urine or Diagnosis organs.
