Lyme arthritis as the incorrect diagnosis in pediatric and adolescent fibromyalgia

In areas endemic for Lyme disease there is increasing concern and anxiety about possible chronic and untreatable manifestations of the disease. The authors have diagnosed fibromyalgia in many patients with chronic musculoskeletal complaints in whom chronic Lyme arthritis had previously been diagnosed as the cause of their joint pains. Fibromyalgia is a common disorder, causing arthralgia (not true arthritis), fatigue, and debility. The repeated and/or long-term antibiotic therapy prescribed for "chronic Lyme disease" is not successful in curing the symptoms of fibromyalgia. Especially in areas where anxiety about Lyme disease is great, it is important to be careful in diagnosing chronic Lyme disease. Fibromyalgia is a potentially treatable and curable cause of chronic complaints and should be considered in the differential diagnosis of "refractory Lyme arthritis."     

Hydrophobic mismatch between proteins and lipids in membranes

During the evaluation of older adults with musculoskeletal complaints, it is necessary to differentiate periarticular conditions from intraarticular or arthritic conditions. It also is useful to classify the symptoms as acute or chronic and as mono-, oligo-, or polyarticular. Close attention should be paid to the history and physical exam findings, while laboratory tests and radiographs should only be used as supporting evidence of a clinical diagnosis. A search for the presence of joint inflammation is particularly important in the diagnostic process. Urgent evaluation is necessary in a patient with an acutely warm and swollen joint to rule out the presence of infection.     

Follow-up results of modified Glenn-Andersen operation in children with primary vesicoureteral reflux

A questionnaire survey covered 11 females with temporal arteritis (CA) and 20 healthy controls. Gastrointestinal, joint and spinal complaints were significantly more frequent in CA patients. Clinical characteristics of joint and spinal disorders in CA patients are close to those of chronic reactive arthritis. It is suggested that Horton's disease may be lacking as a stage of the infectious process in elderly patients (chronic intestinal and/or urinary infection-reactive arthritis-CA). A case is reported where CA developed after intestinal and urinary infection. Administration of antibiotics for treatment of the recurrence induced a continuous remission under reduced doses of glucocorticoids. In another case biseptol + glucocorticoids brought about a persistent remission allowing glucocorticoid discontinuation.     

Familial hypokalemia/hypomagnesemia and chondrocalcinosis

OBJECTIVE: Familial occurrence of Bartter's syndrome is well known, but the simultaneous occurrence of hypokalemia/hypomagnesemia and chondrocalcinosis in one family has not been described. We present the clinical, laboratory and radiological findings of a family, in which 7 members were affected by disease. METHODS: A total of 43 members of the family could be interviewed concerning their general health, past diseases and joint complaints. Serum potassium and magnesium were determined in all and radiographic studies were performed in those who had hypokalemia and hypomagnesemia or those with merely articular complaints. Urinary excretion of potassium, magnesium and calcium were determined in the affected persons. RESULTS: Seven patients were found with hypokalemia and hypomagnesemia. Urinary potassium and magnesium excretion was inappropriately high when compared to the serum levels of these electrolytes. All patients had hypocalciuria and extensive chondrocalcinosis, mainly in the knees, elbows and shoulders. In one patient, most probably as a result of magnesium supplementation, a striking reduction of chondrocalcinosis was observed during a followup of 10 years. CONCLUSION: A family with familial hypokalemia/hypomagnesemia and chondrocalcinosis is described. The reduction of chondrocalcinosis, after years of magnesium supplementation in one patient, suggests that hypomagnesemia is an important factor in the pathogenesis of chondrocalcinosis in these patients.     

Joint impairment and self-reported disability in elderly persons

Recent findings indicating that arthritis is a major contributor to disability in elderly persons are based on self-reported diagnostic information. We conducted physical examinations of the joints at baseline on 541 older persons. We then tested a multivariate model of total/generic disability which included respondent group, demographic and chronic disease variables (joint impairment and comorbid conditions), arthritis pain, and psychological status. Hierarchical multiple regression found that the model explained 55 percent (adjusted R2 = .55) of the variance in baseline disability with joint impairment accounting for 15 percent (change in R2 = .15) of the variance. When joint impairment was removed from the model, arthritis pain worked well as a surrogate. Together, these findings strongly support the importance of musculoskeletal disease in explaining disability in the elderly population.     

The updated guideline 'Gastric complaints' of the Dutch College of General Practitioners; a reaction from a general practitioner]

Three working diagnoses in gastric complaints are presented: aspecific gastric complaints, ulcer complaints, reflux complaints; these assist the general practitioner in formulating the initial diagnostic and pharmacological interventions and in evaluating the effects of therapy. The guidelines state that eradication treatment of Helicobacter pylori is indicated only in gastritis caused by H. pylori, grade IV bulbitis, a duodenal bulb malformation or peptic ulcers.     

Active laboratory consultation for the clinical supporting system in the general hospital

OBJECTIVE: To study demographic, clinical, and radiographic staging patterns in patients with multifocal osteonecrosis to facilitate earlier diagnosis and optimize treatment. METHODS: Multifocal osteonecrosis was defined as disease of 3 or more anatomic sites. Patients were characterized demographically, which included disease associations, corticosteroid and other agent usage, presenting joints, and symptomatology. Radiographically, patients were evaluated with plain radiographs and magnetic resonance imaging (MRI) scans of all joints to determine the presenting stage of the lesions. RESULTS: We found that 32 of 1056 (3%) osteonecrosis patients under our care had multifocal disease. Associated factors included systemic lupus erythematosus (13 patients), inflammatory bowel disease (5 patients), malignancy (4 patients), and renal transplantation (3 patients). Thirty of the 32 patients (94%) had a history of corticosteroid therapy, with the other 2 patients found to have a coagulopathy. All 32 patients had bilateral femoral head involvement and 30 of 32 had bilateral knee involvement, with the other 2 having only left knee lesions. Osteonecrosis was also seen in the shoulder (28 patients), ankle (8 patients), and 3 other sites. Overall, 201 sites were involved (6.3 per patient). The majority of joints presented in a pre-collapse stage (77%). Patients most commonly presented with hip or multiple joint symptoms (22 patients, 69%). In 8 patients, the knee was the sole presenting symptomatic joint and the ankle and shoulder were the sole presenting symptomatic joints in one patient each. CONCLUSION: In patients with a diagnosis of osteonecrosis and complaints in other joints, these other areas should be fully evaluated with plain radiographs and, if inconclusive, with MRI. In patients with osteonecrosis not involving the femoral head, the patient's hips should be radiographically evaluated regardless of whether the patient is symptomatic. Patients diagnosed with osteonecrosis of the knee, shoulder, or ankle should have other joints evaluated, as such patients have multifocal disease roughly 50% of the time.     

The effect on cortical mirror foci produced by ouabain of gamma-aminobutyric acid, dopamine and haloperidol injected into the rabbit caudate nucleus

It is the experience of the urological author that radiculitis secondary to costovertebral joint derangement is the most common cause of lower abdominal pain. However, this pain is sometimes made worse when the patient is subjected to a flank incision for presumed renal disease, since the aftermath of a flank incision may be a downward pull on a rib owing to detachments of muscles attached to its superior surface. Emotional problems, too, befall many patients with radiculitis--despondency over delayed diagnoses or sensitivity at having been told their complaints are psychosomatic. Most often these difficulties disappear spontaneously once the pain is relieved. Definitive diagnosis requires orthopedic techniques. Unfortunately, few orthopedists are well versed or interested in the syndrome of renal pain. When they are, erroneous diagnosis can be corrected and a course of conservative or surgical treatment prescribed, with excellent results.     

The two-factor structure of sleep complaints and its relation to depression and anxiety.

Although sleep complaints are common in depression and anxiety, there is little agreement as to how they should be organized and assessed. It is also unclear whether sleep complaints show specificity with certain disorders or whether they are nonspecific symptoms. The authors examined the structure of sleep complaints and the relations of these complaints to depression and anxiety in 3 samples: college students, older adults, and psychiatric patients. Exploratory and confirmatory factor analyses indicated that sleep complaints consistently defined 2 distinct dimensions: Insomnia and Lassitude. The Insomnia factor included indicators of early, middle, and late insomnia, as well as poor sleep quality. The Lassitude factor included measures of hypersomnia, fatigue, and sleepiness. Both factors were significantly related to symptoms and diagnoses of depression and anxiety. However, Lassitude was more strongly related to symptoms of depression and anxiety than was Insomnia. In addition, Lassitude showed specificity to measures and diagnoses of depression compared with anxiety disorders. This specificity can be explained by Lassitude's relation with negative and positive emotionality, both of which are components of depression.

Pure red cell aplasia associated with true thymic hyperplasia

We reported unique magnetic resonance imaging (MRI) findings of a 57-year-old Japanese man who was diagnosed as Vogt-Koyanagi-Harada disease. This patient presented with complaints of a transient severe headache followed by a bilateral loss of visual acuity and truncal ataxia. Magnetic resonance imaging revealed abnormal contrast enhancement of both the uveas and the cerebellar vermis corresponding to his neurological abnormalities. The distribution and the nature of the resolution of this unusual pattern of contrast enhancement suggested that these MRI findings might illustrate transient destruction of the blood brain barrier or vascular extravasations. Such events might be representative of pathophysiology involving the central nervous system that occurred in patients with Vogt-Koyanagi-Harada disease.     

The delivery of oxygen by a venturi T piece

Thromboembolic events such as deep vein thrombosis (DVT) and pulmonary embolism (PE) are very uncommon in the pediatric age group; even more rare is the white clot syndrome. We present the case of a 13-year-old girl who presented with no known risk factors for thromboembolic disease or cardiopulmonary complaints, yet was found to have extensive lower extremity DVT and PE. This patient also suffered the rare but potentially devastating complication of heparin therapy referred to as the white clot syndrome, resulting in amputation of the lower extremity. Greater awareness of both thromboembolic disease in children and the white clot syndrome may lessen the morbidity and mortality associated with these entities.     

Study on musculoskeletal complaints involving the back, neck and upper limbs

OBJECTIVE & METHODS: A mail questionnaire survey was conducted among designated factory doctors (DFDs) to determine the nature and extent of musculoskeletal aches/pains in patients attending their clinics over one working week. Information was recorded for all patients aged 15 years and above presenting with aches or pains in the back, neck or upper limbs, as the main complaint or as one of the presenting symptoms. RESULTS: For the 155 doctors participating in the survey, the total attendance of patients aged 15 years and above during the study period was 35,010. Of these, 3.9% presented with the symptoms studied and 1.8% had work-related complaints. The commonest site affected was the back (55.7%), followed by the neck (21.4%) and shoulders (19.2%). A higher proportion of males than females had back complaints with the reverse for complaints involving hands/wrists and arms/forearms. 82.3% of the affected were employed, 60.3% being production workers, compared to 33.3% professional/office workers and 6.4% service workers. Of the patients who were working, 51.3% had work-related symptoms and 54.4% were given medical leave. Production workers had the highest proportion with work-related symptoms while service workers had the highest proportion given medical leave. The "medical certificate rate" was highest for back symptoms -57.6%, while work-related symptoms was highest for complaints involving hands/wrists. CONCLUSION: The study findings are consistent with those of a 1993 morbidity survey of outpatients in Singapore and indicate that the prevalence of work-related musculoskeletal aches/pains is not high.     

Pulmonary toxicity of antineoplastic drugs

Pulmonary toxicity caused by antineoplastic drugs is becoming a more frequently recognized entity, and the number of drugs known or suspected of causing this disease is steadily increasing. In general, the initial clinical appearance includes both constitutional signs of malaise and fever, as well as pulmonary complaints. Some clinical signs may suggest a particular drug as the cause. The pathological condition also is generally nonspecific, but some clues may be present histologically that help define the causal agent. This is a review of the antineoplastic drugs that are associated with pulmonary toxicity. Clinical, laboratory, and pathological data are presented as useful information for practicing physicians. Although therapeutic maneuvers are limited, these are discussed with regard to each drug.     

Management of the older patient with acute myocardial infarction: difference in clinical presentations between older and younger patients

The majority of persons sustaining acute myocardial infarction are older, and in these older persons morbidity and mortality are high. Clinical presentations and characteristics are significantly different between older and younger infarction patients. Older infarction patients are more likely to be female and to have a history of heart failure, but they are less likely to have a family history of myocardial infarction, elevated cholesterol, or to smoke. Older patients will frequently have unrecognized or silent myocardial infarctions or, when present, symptoms will be atypical. Instead of chest pain, older patients may have shortness of breath or neurological symptoms, such as confusion. Also, older infarction patients will delay longer in seeking medical assistance after onset of symptoms, and often will not demonstrate ST elevation or Q waves on their electrocardiograms. Not infrequently, older infarction patients will demonstrate major complications such as heart failure or right ventricular infarction on hospital admission, and their presenting complaints will reflect these complications. Because of these atypical presentations and the wide variability of symptoms, physicians must be highly suspicious of the presence of an acute myocardial infarction in older patients who have an unexplained acute change in their physical condition.     

Acute visual change

Changes in vision or loss of vision are common complaints for patients presenting to the emergency department. Such complaints may represent a simple problem related to recent trauma, early evidence of a systemic disease, or may be a vision-threatening lesion. A logical and organized approach to the history and the physical examination of the patient with eye complaints is key to the diagnosis and treatment of the more significant causes of these complaints. This article reviews an organized approach to the patient with complaint of visual loss and considers the wide differential diagnosis. It focuses specifically on the evaluation of the patient complaining of visual changes resulting from central retinal artery occlusion, central retinal vein occlusion, retinal detachment, acute angle-closure glaucoma, giant cell temporal arteritis, and retrobulbar hemorrhage.     

Treatment of myocardial ischemia and myocardial infarction in the elderly

The diagnosis of coronary artery disease in the elderly is problematic because older patients often present atypical symptoms or are asymptomatic. Once coronary disease is diagnosed, the proper course of treatment is not always clear, since few studies have focused on patients older than 65 years. Moreover, older patients often have medical conditions that may aggravate coexisting cardiovascular problems or interfere with conventional pharmacotherapy. For these reasons many physicians who treat cardiovascular problems aggressively in younger patients are reluctant to do so in older individuals. There is considerable evidence, however, that older patients could benefit as much or more from aggressive therapy because of their greater risk of mortality from myocardial ischemia and infarction.     

Complaints of memory loss in the elderly

Frequency of memory complaints increases with age. Such complaints can be the presenting symptom of Alzheimer's disease. Most cases, however, are not related to Alzheimer's disease. They are included in the constructs of benign senescent forgetfulness or age-associated memory impairment. In the later, memory complaints are considered as the subjective counterpart of the age-associated decline in memory test performance. Actually, memory complaints are associated with various factors: perceptual disorders, general health, functional disability, affective disturbances, psychosocial changes... The first step in the management of memory complaints is to rule out Alzheimer's disease and affective disturbances which could require specific therapeutic measures. Most often, memory complaints are the only presenting symptom: the signification of complaints should be analysed in each individual considering all the possibly causal factors in order to elaborate the appropriate management.     

Negative affect and self-report of physical symptoms: Two longitudinal studies of older adults.

The ability of negative affect (NA) to predict somatic complaints 6 months later was examined. State NA, including anxious affect (AA) and depressive affect (DA), was measured in 2 separate samples of older adults averaging 62 and 73 years of age. In the first study, DA reliably predicted later complaints, and a corresponding trend was noted for NA. The second study showed that state NA and its 2 constituent variables predicted somatic complaints associated with acute illness (e.g., colds) 6 months later. The second study also examined trait measures of the 3 predictor variables and found that NA and AA, but not DA, were associated with subsequent somatic complaints. However, these trait effects were less robust than those attributable to their state counterparts. The authors conclude that negative mood states are the more consistent predictors of later physical symptom reports. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
