Influenza-B virus was identified in 102 children admitted to hospital during two epidemics in 1973 and 1974, enzbling the symptomatology of infection with this virus to be assessed in detail for the first time. Abdominal pain, often severe enough to require differentiation from acute appendicitis, emerged as a dominant symptom, especially in older children. Respiratory symptoms were often insignificant, although the lower respiratory tract was sometimes involved. Other symptoms in some children included convulsions and acute myalgia. The immunofluorescent method of virus diagnosis was found to be reliable for influenza B, except in a few cases ehere nasopharyngeal secretions were scanty, giving 97-5 percent copositivity with standard isolation techniques. The rapid result provided by immunofluorescence was helpful in clinical diagnosis and management and also in the control of hospital cross-infection.

14 subjects with influenza or echovirus infection, all suffering myalgia, and 9 subjects with mumps, in whom this symptom was lacking, were investigated with single fibre electromyography (EMG) in the acute phase and during convalescence to reveal a possible disturbance in neuromuscular transmission. In both groups about the same percentage of the potential pairs studied showed abnormal transmission characteristics in the acute phase. Two weeks after the acute infection, this percentage had decreased significantly in the group with myalgia, whilst in the non-myalgia group it was still at the same level. However, on both occasions of investigation and in both groups the percentages were substantially greater than those recorded in healthy individuals. This study demonstrates that acute febrile infections may adversely affect neuromuscular transmission in previously healthy human subjects. The effects observed might offer an explanation to the accentuated muscular weakness in association with infections in patients with an already low safety margion of neuromuscular transmission, e.g. in myasthenia gravis.

Seventy-one men who were given live-attenuated A/Hong Kong/68 (H3N2) influenza vaccine during November 1973, and 34 men given placebo were examined for changes in antibody level. Overall, 12 of the 71 men (17%) given the vaccine showed a fourfold rise in haemagglutination-inhibition (HI) antibody titre after 14 days. No such rises were seen in the 34 men given placebo. However, 10 of the men showing a fourfold rise were from 19 who had no detectable HI antibody to this virus before vaccination, representing a conversion rate of 53%. The other two had a HI titre of 1/10 before vaccination. The absence of antibody response, at 14 days, in those with an HI titre of 1/20 or greater may indicated that this represents a protective level against infection. However, the vaccine virus was probably overattenuated and may have constituted a weaker challenge than might occur with a wild strain. No influenza virus was isolated from either group in the week after vaccination and no evidence of transmission to the placebo group was seen. Mild symptoms, chills, muscle pain, and stiffness were more frequently seen in the 12 persons showing a fourfold rise in antibody than in the rest of the volunteers.

We report two cases of a syndrome related to the bowel bypass surgical procedure. This syndrome consists of a flu-like illness, with temperatures from 38.3 to 39.4 degrees C (101 to 103 degrees F), chills, malaise, and inflammatory papules and pustules, 2 to 4 mm in diameter, on the extremities and upper part of the trunk. The illness lasts two to six days, and then recurs in one to six weeks. During some episodes, myalgia and polyarthralgia occur; between episodes, joints are normal. In both patients, extensive evaluations had been made to determine the cause of the persistent illness before this distinctive syndrome, related to the bowel bypass surgical procedure, was recognized. These two cases are also illustrative of the two therapeutic approaches that may be of value: administration of antibiotics, esecially metronidazole, or reconstitution of the normal bowel anatomy. The relationship of this syndrome to the arthritis associated with bowel bypass and to bypass enteropathy is discussed.

Previous nuclear disease was found twice: Mc Ardle disease, dermatomyositis. Causative factors were: strenous exercise, hyperthermia, intoxication, influenza. Myalgias and/or myoedema was recorded in ten cases, associated with an hypovolemia of variable severity in eight. Oligo-anuria was observed in eight cases. The acute renal failure (ARF) was characterized by an increase in the serum creatinin more important than the rise in the blood urea and, in some cases, severe metabolic disturbances: hyperkaliema (6 cases), hypocalcemia (5 cases), hyperphosphatemia (5 cases) and hyperuricemia (5 cases). Diagnosis was made by the increase in sera of the muscles enzymes, specially the CPK and the search for myoglobinuria, positive during the first seven days. A complete recovery of renal function was observed in the nine survivors with a transient and moderate hypercalcemia in three. Three patients had persistant neuro-muscular deficiencies. Non traumatic rhabdomyolysis is not a rare cause of ARF and should be considered when the etiology of ARF is uncertain.

An outbreak of acute crural myalgia in children is reported. The severe calf pain followed an influenza-like episode, with subsequent complete recovery. Laboratory studies in most cases showed elevated creatine phosphokinase and SGOT values, with a low peripheral white blood cell count. Electromyographic studies were normal. Results of one muscle biopsy were normal. This postviral myalgia is a distinctive syndrome only recently being recognized in the United States.

During the first week of March 1974, a hospitalized patient being evaluated for hyperproteinemia and hypertension experienced fever, chills, and myalgia and showed pulmonary signs consistent with diffuse pneumonia. Subsequently, the findings from serologic tests confirmed that the patient had viral influenza. Seven other compromised hosts on the same ward developed symptoms of pneumonic influenza, and serologic data on three of the seven confirmed influenza A2. Additionally, a previously healthy young adult admitted with acute respiratory distress died of nonbacterial complications and was shown to have community-acquired influenza. The unusual features of the epidemic were the intrahospital localization of the epidemic in compromised hosts, the high rate of pneumonic complications, the low rate of secondary bacterial infection, and the severity of the viral pneumonia in the community-acquired case.

Ten children, three girls and seven boys, aged 4-10 years, were admitted with benign acute childhood myositis during spring and winter months (March 1988 to March 1990). They presented with an acute onset of symmetrical calf muscle pain and tenderness, weakness and inability to walk a few days after a flu-like illness. All had raised serum creatine kinase and a normal erythrocyte sedimentation rate, and the majority had low peripheral white blood cell counts with relative lymphocytosis. Serum aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase were found to be raised in four patients. Virological studies performed in six children gave negative results. Full clinical recovery was achieved within 1-7 days. One child developed a second episode. These ten cases of benign acute childhood myositis are the first to be reported from this region.

The aim of this 16-week trial was to determine the safety and efficacy of a step-care regimen of ramipril, an angiotensin converting enzyme inhibitor, from the minimal active dose (2.5 mg) in patients treated for mild to moderate hypertension. The trial was conducted by 102 general practitioners in 770 patients with mild to moderate hypertension. After a response rate to a 4-week placebo therapy of 9.1%, 57.0% of patients given active treatment with ramipril responded to daily doses of 2.5 mg. Ramipril 5 mg daily was effective in 55.6% of the remaining patients. There was no apparent statistically significant difference between the treatments with ramipril 10 mg or a combination of ramipril 5 mg + Lasix 20 mg daily (44.7% and 47.4% response respectively) in a 6-week double-blind arm of the study. In total, more than 90% of patients responded to treatment with ramipril by the end of the study. The incidence of adverse events was generally low, such as headache, cough, dizziness, asthenia, cramps and nausea. The incidence of cough appeared to be related both to the dosage of ramipril given and to outbreaks of influenza syndrome. Thirty-eight patients discontinued active treatment as a result of minor events such as cough, dizziness or diarrhoea, and one case each of myalgia and papular rash. There were no significant variations in laboratory parameters during the study, especially fasting blood glucose and apolipoprotein A1 and B. The results of this study provide evidence of the safety and efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)
