The case is reported of a 45-year-old woman who was being treated for chronic back and right leg pain with intrathecal morphine administered via a subcutaneous continuous-infusion device. She received an accidental 450-mg bolus injection of morphine intrathecally and developed hypertension, status epilepticus, intracerebral hemorrhage, and respiratory failure. Treatment with continuous intravenous naloxone infusion, lumbar catheter drainage of cerebrospinal fluid, and control of hypertension and status epilepticus resulted in an excellent outcome with return to neurological baseline. Care providers who refill pump reservoirs with morphine must be knowledgeable about these devices and the life-threatening consequences associated with errors in refilling them. This case describes the complications and successful treatment of high-dose intrathecal morphine overdose.

To assess the role of demographic factors and chronic conditions in maintaining mobility in older persons, this study utilized longitudinal data collected as part of the Established Populations for Epidemiologic Studies of the Elderly between 1981 and 1987 on 6,981 men and women aged 65 years and older in East Boston, Massachusetts; Iowa and Washington counties, Iowa; and New Haven, Connecticut. Results are presented for those who at baseline reported intact mobility, defined as the ability to climb stairs and walk a half mile without help, and who were followed annually for up to 4 years for changes in mobility status. Age, income, education, and chronic conditions present at baseline and occurring during follow-up were evaluated for their association with loss of mobility. Over the follow-up period, 55.1% of subjects maintained mobility, 36.2% lost mobility, and 8.7% died without evidence of mobility loss prior to death. In both men and women, increasing age and lower income levels were associated with increased risk of losing mobility, even after controlling for the presence of chronic conditions at baseline. After adjustment for age, income, and chronic conditions, lower education levels were a significant risk factor for mobility loss in men, but not in women. Baseline reports of previous heart attack, stroke, high blood pressure, diabetes, dyspnea, and exertional leg pain were associated with small but significant risks for mobility loss. There was a stepwise increase in the risk of mobility loss according to the number of chronic conditions present at baseline that was very consistent between men and women. The occurrence during the study of a new heart attack, stroke, cancer, or hip fracture was associated with a substantially greater risk of mobility loss than was associated with the presence of these conditions at baseline.

Lumbar intervertebral disc herniation, although common in adults, is infrequent in the young, and especially in patients under 17 years old. In this work we review clinical data pertaining to two pediatric groups of patients whose main complaint was low back pain and/or sciatica, trying to identify factors that might contribute to their earlier referral and to the differential diagnosis of protruded disc and spinal neoplasm in this population. Group A comprises 17 youngsters diagnosed as having lumbar herniated nucleus pulposus and group B, 16 children with neoplasms of the lower thoracic and lumbosacral regions. Both groups were similar in sex distribution and symptoms of pain and numbness. However, there was a striking difference in age at presentation. No patient in group A was younger than 11 years, while most of those in group B were in their first decade of life (P = 0.018). The classic clinical onset in the children with herniated discs started with low back pain and sciatica, as in the children with neoplasms, although in subgroup B leg pain tended to be bilateral. The usual examination findings in both groups were spinal rigidity and sensory loss, but motor weakness and impaired reflexes were found to be more frequent in the group with spinal growths (P = 0.02). Children with lumbosacral neoplasms also tended to present with atypical symptoms (acute onset, intracranial hypertension, subarachnoid hemorrhage and abdominal pain), while this was the exception in the group with herniated discs. Plain radiographs of the pediatric spine showed that X-ray examination is still a good tool for diagnosing spinal growths compared with their scant utility in disc herniations (P = 0.001). During the survey we were impressed by the children's apparent good tolerance to pain, which is probably due to the lack of the emotional component of pain in adults and explains their delayed referral for neurosurgical consultation. However, all modalities of treatment seemed to be effective in children, chemonucleolysis and surgery being extraordinarily effective in this age group. Accordingly, we see no reason for long-term conservative therapy in children with lumbar and sciatic pain; on the contrary, we believe these patients should be offered earlier neurosurgical treatment.

A case of Erdheim Chester disease in a 51-year-old Turkish patient is described. Erdheim Chester disease is a rare form of lipoid granulomatosis. Knee and leg pain are the most common symptoms, and physicians working in orthopaedics and traumatology are the first to be consulted. Our patient demonstrated a typical bilateral, symmetric sclerosis of the metaphyseal region of long bones of the lower extremity, histologic examination revealed foamy, lipid-loaded histiocytes. The patient also suffered from arterial hypertension, diabetes insipidus and exophthalmos of the left eye. The diagnosis was confirmed by a bone biopsy, and the patient was treated with non-steroidal anti-inflammatory drugs, corticosteroids and vincristine.

A 45-year-old Mexican woman with a history of noninsulin dependent diabetes mellitus (NIDDM), hypertension, and coronary artery disease presented to the hospital after 2 months of intractable nausea, vomiting and diarrhea-all made worse by eating and drinking. She reported fever, chills, anorexia and a documented 50-pound weight loss during this period. She denied the signs and symptoms of melena, hematochezia, steatorrhea or constipation. She also reported left leg pain and decreased sensation and strength of her left leg compared to the right leg. She had been hospitalized 2 weeks prior to admission with the same symptoms and a diagnosis of viral gastroenteritis. She was also treated for H. pylori, but subsequent biopsy results were negative by Steiner stain.

The Indian Contraceptive Testing Unit started making field trials with oral contraceptives in 1964. By June 1968, 958 women were taking oral contraceptives. Combination tablets used contained a minimum amount of progestogen (.5-3 mg) and a suitable amount of estrogen. The 21-tablet pack was found mot suitable. It was found that if a woman missed taking the tablets in the latter half of the cycle usually no harm resulted, but if she missed them at the beginning of the cycle pregnancy might follow as ovulation would not be inhibited. Main contraindications are liver damage, toxic hyperthyroidism, thromboembolic disease, and cancer of the genital tract or breast. Caution is advised for persons with chronic nephritis, a history of eclampsia, hypertension, varicose veins, ophthalmological disorders, or psychic depressive states. Side effects have been less with the smaller doses. The most serious side effect is thromboembolism. Those reported have been leg pain, giddiness, headache, breakthrough bleeding, nausea, vomiting, amenorrhea, abdominal pain, weakness, increased blood pressure, and skin rashes. Others have reported ocular disease and cranial nerve palsy. Sequential therapy has been reported to have a lower incidence of side effects but a higher rate of pregnancy. Low-dose progestogen therapy, the "minipill," does not inhibit ovulation but is effective by causing changes in the endometrium and in the mucus. The chlormadinone in the minipill does not affect lactation. However, the incidence of pregnancy is similar to that with an IUD (Lippes loop) which is 2.6/100 cases. Laboratory tests have been normal, except an increase in the thymol turbidity test. Vaginal cytology has revealed no case of malignancy. Results show that oral contraceptives are suitable for use on a mass scale as a method of population control.

Guidelines are provided for women who use minipills. Minipills are low dose, progestin only oral contraceptives (OC), which are frequently prescribed for women who 1) experience estrogen related side effects if they take combined OCs; 2) are 35 years of age or older; 3) are 30 years of age or aver and smoke; 4) have a history of headaches, hypertension, or varicose veins; 5) desire immediate postpartum protection; or 6) are lactating. Minipills prevent pregnancy by inhibiting ovulation and implantation and by making the cervical mucus more impervious to sperm penetration. Minipills can be effective if they are used properly. Women who take minipills should be advised to carefully read and follow the instructions provided in the OC packet, initiate pill taking on the 1st day of menstrual bleeding, and take 1 pill every day without and breaks. A backup method should be used during the 1st month and subsequently, during each midcycle phase. If a woman misses 1 pill, she should immediately, upon remembering, take a pill, take her next day's pill at regular time, and use a backup method until menstruation reoccurs. If a woman misses 2 pills, she should immediately, upon remembering, take 2 pills, take 2 pills the following day, and use a backup method until menstruation begins. Women should be advised that many minipill users experience irregular menstural cycles, including amenorrhea and spotting between periods. If menstruation is delayed for 45 days, a pregnancy test is advisable. Women should be advised to immediately seek medical attention if they experience severe chest pain, shortness breath, severe headaches, vision problems, or severe leg pain. Minipill users should let their clinicians know if they experience and changes in mood or sexual drive. These problems can frequently be avoided by switching to another brand of minipills.

We described longitudinal changes of movement performance in a population-based sample of women followed from age 70 to 78. We also studied the cross-sectional relationships between medical conditions and movement performance at baseline, and longitudinal relationships between baseline medical conditions and changes of movement performance. Two hundred and thirty-four women aged 70 years participated in the baseline study, and 88 women participated in a follow-up study 8 years later. Movement performance was measured by an optoelectronic test, the postural-locomotor-manual (PLM) test, which objectively and precisely measures the subject's mobility of lower and upper extremities. Information on medical conditions including selected diseases and symptoms were obtained by self-report and/or by physical examination. Movement time (MT), an indicator of the overall movement performance of the PLM test, increased over 8 years. This change was mainly related to prolonged duration of the locomotor phase (walking forward), but not to the duration of the manual phase (goal-directed arm reaching). At baseline, poor PLM performance was related to hypertension, orthostatic hypotension, cerebrovascular diseases, chronic bronchitis, depression, arthritis, dizziness, chest pain, dyspnea, joint problems, leg pain, tiredness, number of diseases and number of symptoms at baseline. Increased MT during follow-up was associated with arthritis and dyspnea at baseline, and newly developed diseases during follow-up. Our study results indicated that 70-year-old women had a general slowing of their movement performance over 8 years. Age-related decrements of movement performance were more striking in the lower extremities than in the upper extremities. Arthritis and dyspnea at baseline, and incident diseases during follow-up were related to this age-related decline of movement performance.

Most abdominal aortic aneurysms (AAAs) are asymptomatic, not detectable on physical examination, and silent until discovered during radiologic testing for other reasons. Tobacco use, hypertension, a family history of AAA, and male sex are clinical risk factors for the development of an aneurysm. Ultrasound, the preferred method of screening, is cost-effective in high-risk patients. Repair is indicated when the aneurysm becomes greater than 5.5 cm in diameter or grows more than 0.6 to 0.8 cm per year. Asymptomatic patients with an AAA should be medically optimized before repair, including institution of beta blockade. Symptomatic aneurysms present with back, abdominal, buttock, groin, testicular, or leg pain and require urgent surgical attention. Rupture of an AAA involves complete loss of aortic wall integrity and is a surgical emergency requiring immediate repair. The mortality rate approaches 90 percent if rupture occurs outside the hospital. Although open surgical repair has been performed safely, an endovascular approach is used in select patients if the aortic and iliac anatomy are amenable. Two large randomized controlled trials did not find any improvement in mortality rate or morbidity with this approach compared with conventional open surgical repair.

Peripheral arterial disease (PAD) in the elderly can be: 1) asymptomatic, 2) associated with intermittent claudication, or 3) cause critical limb ischemia. Persons with PAD are at increased risk for all-cause mortality, cardiovascular mortality, and mortality from coronary artery disease (CAD). Hypertension, diabetes mellitus, dyslipidemia, and hypothyroidism should be treated, and smoking should be stopped. Statins reduce the incidence of intermittent claudication and increase exercise duration until the onset of intermittent claudication in persons with PAD and hypercholesterolemia. Antiplatelet drugs (eg, aspirin, clopidogrel, angiotensin-converting enzyme [ACE] inhibitors, statins) should be given to all persons with PAD. Beta blockers should be given if CAD is present. Exercise rehabilitation programs and cilostazol lengthen exercise time until leg pain develops. Chelation therapy has no scientific basis and should be avoided. Revascularization or amputation may be indicated in some cases.
