Increased lumbar lordosis places increased stress on the pars interarticularis. Fatigue fractures of the pars can result in spondylolysis. There was a 50% incidence of asymptomatic spondylolysis in 18 patients who had Scheuermann's kyphosis and an increased lumbar lordosis. This significant increase further confirms the pathogenesis of spondylolysis. Patients with Scheuermann's disease with low-back pain should be evaluated with oblique radiographs of the lumbar spine to rule out spondylolysis.

Torasemide 40 mg/day p.o. was administered for 21 days to 8 healthy volunteers to investigate its pharmacodynamics, pharmacokinetics and safety on chronic administration. It induced a highly significant initial increase in 24-h urinary volume and 24-h excretion of sodium and chloride, but its affect diminished after the first days. On Days 0, 1, 10 and 21 the experiment was divided in 3 clearance phases, extending from 0 to 2 h, 2 to 6 h and 6 to 24 h after dosing. The fractional excretion of sodium, chloride, potassium, calcium, magnesium and inorganic phosphates peaked during the first 2 h and returned almost to the control value during the following two clearance phases. The phase-dependent changes were significant for all electrolytes, except for potassium and inorganic phosphate. Plasma electrolyte levels remained constant throughout the study, except for a small decrease in chloride and potassium and for an increase in calcium and magnesium. Fasting blood glucose and glucose tolerance test were unaffected. A small but significant decrease in LDL-cholesterol was observed on Day 10. Other plasma lipid components showed minor changes. Plasma uric acid levels were moderately increased. There was no significant change of the creatinine clearance. Body weight fell significantly (by about 2 kg) during the study. Tonal audiometry was normal before and after the study. There was no significant difference between the plasma levels of torasemide on Days 1, 10 and 21, nor between its elimination half-life on Days 1 and 21. Side-effects consisted mainly of fatigue and low-back pain on days of intense diuresis.(ABSTRACT TRUNCATED AT 250 WORDS)

We have observed a high frequency of chronic Candida albicans infection and of allergic sensitization to candida among patients with normocalcemic latent tetany (LT). Among 50 LT patients, 34% suffered from recurrent or chronic candida infection by history, 24% showed evidence of active infection and 48% demonstrated type I hypersensitivity to C. albicans extract on intradermal testing. Treatment with oral antifungal drugs and allergy desensitization to Candida produced complete relief of symptoms in 44% of the patients, with remission occurring for symptoms of depression, irritable bowel syndrome, fatigue, premenstrual tension, headache, anxiety and back pain. The complex relationship between candidiasis and Mg deficit is discussed. Patients with LT, refractory symptoms and a history of prolonged antibiotic exposure or recurrent candida infection should be considered for oral antifungal therapy and candida desensitization.

In 100 patients with irritable bowel syndrome a wide variety of non-gastrointestinal symptoms were significantly more common than in a group of 100 age, sex, and social class matched controls. Nocturia, frequency and urgency of micturition, incomplete bladder emptying, back pain, an unpleasant taste in the mouth, a constant feeling of tiredness and in women dyspareunia were particularly prominent (p less than 0.001). With reference to non-colonic gastrointestinal symptoms nausea, vomiting, dysphagia and early satiety were very common (p less than 0.0001). This symptom diversity was observed irrespective of whether the patient had a psychiatric disorder or not. Patients smoked more than controls (p = 0.02) drank more caffeine containing drinks (p = 0.03) and 26% had taken at least one week off work in the previous 12 months. Thirty three per cent of patients had a family history of irritable bowel syndrome. Cognisance of these diverse symptoms may prevent referral to the wrong medical specialty and inappropriate investigation. They may also be indicative of a much more diffuse disorder of smooth muscle than has previously been appreciated.

The clinical features of 150 consecutive patients with irritable bowel syndrome are reported. All patients were referred to a private practice. There was a marked female preponderance and a wide range of ages. Diarrhoea was predominant in 61,3%. The common symptoms were altered bowel habit, abdominal pain, emotional disturbance, flatulence and distension. Fatigue, weight loss, upper gastrointestinal symptoms, backache and urinary symptoms were frequent. The rectum showed nonspecific loss of vascular pattern, oedema and congestion in 11,4% of patients, but this was readily distinguished from inflammatory bowel disease on histological examination. The incidence of non-smokers in the group was 78,1%. The overall appendicectomy rate was 34%, and 65% of the 92 women had had gynaecological operations. A positive diagnosis was made on a typical history and simple basic investigations. More extensive investigations were required for those patients with markers of organic disease, but these yielded few associated lesions.

The effect of norethisterone enanthate on clinical and biochemical parameters was studied in 9 normal women aged 21-29 years. Blood samples were taken before and 2, 6, 10, and 14 weeks after injection. Significant changes in serum proteins were observed, as was a significant increase in blood coagulability. Serum triglycerides were significantly lower. Thrombosis and effects on adrenal cortex function and on glucose tolerance were not observed. Side effects included breakthrough bleeding, nausea, headache, fatigue, nervousness, breast tension, and backache.

Vibrational effects have been found to be associated with increased frequency of low-back pain in various industries, and because of this the study herein reported was conducted to assess the physiologic response of the spinal system to sinusoidal vibrations. A device replicating industrial vibration was constructed and employed on healthy human volunteers to determine the stiffness, impedence, and resonant characteristics of the subjects. Three peaks of enhanced transmissibility corresponding to the resonant frequency of the spinal system were found. The greatest transmissibility of vibratory input occurs at the first resonant frequency (5Hz) where marked enhancement of vibrational input occurs as vibrations pass through the spinal system. A progressive stiffening of the system occurs in response to vibrational inputs of increasing frequency. The effects of posture, the Valsalva maneuver, and fatigue alter the normal response. Structures vibrated at the first resonant frequency have greater potential for damage.

A quantitative study of the trunk muscle strength and fatigability was performed using an isokinetic dynamometer to determine the role of trunk muscles in the low-back-pain syndrome and in particular to investigate the correlation of trunk muscle strength and lumbar lordosis. Most patients demonstrated a generalized weakness of the trunk muscles. The trunk muscle strength of patients suffering from backache for less than one month was significantly lower than that of the controls. The strength of the trunk muscles was not influenced by the duration of symptoms. There was no imbalance between the trunk flexors and extensors. The patients with back pain had a greater fatigability of the trunk flexors than the controls. There was negative correlation between the trunk muscle strength or fatigue and lumbar lordosis.

The relationship of low-back pain (LBP) to other diseases and to cardiovascular risk factors was studied in a random sample of 940 men from 40 to 47 years of age. The life-time incidence of LBP was 61%, the prevalence 31%. The prevalence of other diseases was the same as in previous studies in the same region. In a univariate analysis nine variables were found to be correlated to LBP; angina pectoris, calf pain, breathlessness on exertion, smoking, physical activity at work and during leisure time, worry and tension, fatigue at the end of the workday, and perception of stress. When the influence of other variables was assessed by analysis of covariance, four of the variables maintained a direct association with LBP, viz, calf pain on exertion, smoking, a high physical activity at work, and a frequent feeling of worry and tension.

Although the epidemiologic evidence is not convincing, a number of studies indicate that those exposed to dynamic loads may have increased risk to low-back disorders. A review of the available evidence suggests that chronic low-back pain relates to disc degeneration and that this in turn may be accelerated by mechanical failure in the region of the end-plate and subchondral bone or in the annulus. Two hypotheses are proposed to relate fatigue induced failure of vertebral tissues to disc degeneration. The extent of dynamic stresses on the vertebral motion segment arising from transport are investigated, and the results indicate that fatigue induced failure is a distinct possibility. The implications of these suggestions for environmental health protection are briefly discussed.
