[Q]: Abstract: It is not uncommon for thyrotoxicosis to appear in an atypical manner in older patients. The classical symptoms are often absent. The disease is frequently characterized by cardiac, gastrointestinal, neuromuscular, and neuropsychiatric symptoms. As hyperthyroidism is readily amenable to effective treatment that can improve the quality of life, the clinical suspicion of this disease is always indicated and exclusion of this diagnosis should always be pursued. Recognizing the admittedly great difficulty in making, or even suspecting, the diagnosis of hyperthyroidism in the elderly, our rule is to test for hyperthyroidism in essentially all geriatric patients presenting chronic systemic symptoms or signs. On the other hand, we do not recommend community-wide screening of persons over 60 for hyperthyroidism. Community-wide screening falls far below the break-even point in cost-benefit analysis. The most sensible detector of hyperthyroidism now widely available is the serum free T3 index (FT3I), but it may be falsely normal because of the effect of systemic illness on extrathyroidal T4-to-T3 conversion. The advent of ultrasensitive methods for TSH may change these statements considerably. It may become the single screening procedure for both hyper- and hypothyroidism.

[Q]: Abstract: Methods of delivery, maternal and neonatal characteristics were examined to determine their role in the occurrence of Erb/Duchenne's palsy. Data from 210,947 Washington state birth certificates from 1980 through 1982 were examined. The incidence was 50.2 cases of Erb's palsy per 100,000 live births. A case control study design was used to analyze 106 cases and 386 controls by both univariable and multivariable analysis. Birth weight was shown to be a significant risk factor regardless of which method of delivery was used. A high birth weight infant (4001-4500 g) had 2.5 times the risk of incurring an upper brachial plexus injury compared with normal size infants (2501-4000 g). The risk for infants greater than 4500 g increased another tenfold (OR = 21.0). When birth weight was controlled for in the analysis, midforceps (OR = 18.3), vacuum extraction (OR = 17.2), and low forceps (OR = 3.7) remained significantly associated with the Erb's palsy. Delivery by cesarean section was associated with a significant protective effect (OR = 0.5) compared with instrumental vaginal delivery. These data demonstrate a high risk for serious birth injury associated with instrumental midpelvic delivery.

[Q]: Abstract: Adipocytes from spontaneously hypertensive rats (SHR) are not as responsive to isoproterenol or dibutyryl adenosine 3',5'-cyclic monophosphate (cAMP) stimulation compared with Sprague-Dawley or Wistar-Kyoto rats. Lipolytic activity in adipocytes from trained normotensive rats was enhanced in response to 1 microM isoproterenol and 0.5 mM dibutyryl cAMP but not in adipocytes from trained SHR. Decreases in isoproterenol-stimulated (1 microM) cAMP accumulation were evident in adipocytes from trained normotensive rats but not in adipocytes from trained SHR. Basal and agonist-induced lipolysis in fat cells isolated from both normotensive rats and SHR immediately following a 60-min run was increased in both sedentary and trained rats. Adenylate cyclase activity in fat cell membranes was blunted in sedentary and trained SHR both in the absence and presence of 100 microM 5'-guanylyl imidophosphate. No apparent differences existed in antagonist affinity of binding sites for the antagonist dihydroalprenolol in normal rats or SHR. Evidence for a change in affinity of agonist isoproterenol might be indicated based on the enhanced potency of isoproterenol to stimulate lipolysis in trained normal rats. beta-Adrenergic receptor density and antagonist affinity were not different in normotensive rats and SHR in response to training. However, displacement of [3H]dihydroalprenolol in adipocytes from SHR required greater concentrations of isoproterenol compared with adipocytes from normotensive rats, further suggestive of increased agonist affinity of binding sites in normal rats. These data suggest a postreceptor lesion of the lipolytic pathway in adipocytes from spontaneously hypertensive rats, possibly at the guanine nucleotide regulatory protein level.(ABSTRACT TRUNCATED AT 250 WORDS)
