Symptoms of infection in the elderly may be absent, vague or atypical. Infection should be suspected when an elderly patient presents with a decline in well-being or with non-specific symptoms such as falls, dizziness, confusion, anorexia or weakness. Common infections include bacterial pneumonia, urinary tract infection, intra-abdominal infections, gram-negative bacteremia and infection of decubitus ulcers. Antibiotic therapy is not recommended for asymptomatic bacteriuria or locally infected decubitus ulcers. Drug dosages should be adjusted for the age-associated decline in renal function and for hepatic or renal insufficiency. The trend in antibiotic therapy is evolving toward the use of third-generation cephalosporins instead of aminoglycosides to avoid the side effects of nephrotoxicity and ototoxicity. Pneumococcal, influenza and tetanus/diphtheria immunizations help prevent morbidity and mortality.

From January 1979 through March 1988, our regional poison center, located many hundreds of miles from the nearest coastal salt water, documented 23 cases of envenomation by "Lionfish" (members of genus Pterois). All cases involved specimens which were maintained in the homes of amateur aquarists. A study of patient epidemiology showed the following: patient's sex 91.3% male, 8.7% female; patients ages ranged from 17 to 50 years with an average age for males of 29.8 years and 35 years for females; the site of the envenomation accident was always in the home; the only part of the body envenomated was the hand or finger; and all of the patients were symptomatic. Symptoms noted included sharp pain, swelling, redness, bleeding, nausea, numbness, joint pain, anxiety, headache, disorientation, and dizziness. One patient had a complication of cellulitis. Treatment provided included immersion of the effected area in hot water at 40 C for 60 to 90 min, analgesics, tetanus toxoid, and antibiotics. There were no deaths noted and treatment proved effective in all cases. This paper also discusses the natural history, clinical effects, and current treatment for envenomations from these beautiful but dangerous venomous fish, which can cause poisoning exposures that are likely to be encountered by poison centers anywhere in the world.

Gastrodia elata (G. elata) is a traditional Chinese herbal medicine for treating headaches, dizziness, tetanus, and epilepsy. In this study, differential methanol (MeOH) extracts of G. elata were found to prevent serum-deprived rat pheochromocytoma (PC12) cell apoptosis by the MTT assay and Hoechst staining. A serine/threonine kinase inhibitor attenuated this protection. G. elata resulted in phosphorylation and dephosphorylation of ERK1/2 and JNK1/2-p38 MAPKs (members of the serine/threonine kinase family), respectively, as revealed by Western blot analysis. An upstream ERK inhibitor attenuated G. elata-induced ERK phosphorylation but not protective effect. Although JNK and p38 inhibitors attenuated their related enzyme activities during serum deprivation, only JNK inhibitor prevented serum-deprived apoptosis. Thus, G. elata prevents serum-deprived apoptosis through activation of the serine/threonine kinase-dependent pathway and suppression of JNK activity.

Mesobuthus martensii Karsch, commonly known as the Chinese scorpion or Manchurian scorpion, has been used in traditional Chinese medicine as Quanxie to treat chronic pain, tetanus, tremors, convulsion, and paralysis for more than a thousand years. We report a case of poisoning after ingestion of a teaspoon of Quanxie powder. The patient presented with chest pain, dizziness, diaphoresis, generalised involuntary limb twitching, and hypertonia around 15 minutes post-ingestion. The patient recovered uneventfully after supportive management. Intravenous diazepam appeared to be effective in alleviating limb twitching. Failure to accurately measure the dose and to boil before consumption may have contributed to his clinical toxicities.
