Epidemiology of fractures in England and Wales

Records from the General Practice Research Database were used to derive age- and gender-specific fracture incidence rates for England and Wales during the period 1988–1998. In total, 103,052 men and 119,317 women in the sample of 5 million adults sustained a fracture over 10.4 million and 11.2 million person-years (py) of follow-up. Among women, the most frequent fracture sites were the radius/ulna (30.2 cases per 10,000 py) and femur/hip (17.0 per 10,000 py). In men, the most common fracture was that of the carpal bones (26.2 per 10,000 py); the incidence of femur/hip fracture was 5.3 per 10,000 py. Varying patterns of fracture incidence were observed with increasing age; whereas some fractures became more common in later life (vertebral, distal forearm, hip, proximal humerus, rib, clavicle, pelvis), others were more frequent in childhood and young adulthood (tibia, fibula, carpus, foot, ankle). The lifetime risk of any fracture was 53.2% at age 50 years among women, and 20.7% at the same age among men. Whereas fractures of the proximal femur and vertebral body were associated with excess mortality over a 5 year period following fracture diagnosis among both men and women, fractures of the distal forearm were associated with only slight excess mortality in men. This study provides robust estimates of fracture incidence that will assist health-care planning and delivery.     

Epidemiology of femoral fractures in children in the West Midlands region of England 1991 to 2001

We have attempted to describe the epidemiology of femoral fractures in children in the West Midlands region of the National Health Service in England. Our source of data was the Regional Hospital Episode Statistics database for the years 1991-2 to 2001-2. Cases were defined as emergency hospital admissions in patients aged under 16 years, with a diagnostic code of femoral fractures in any field, and resident in the West Midlands. Between 1991-2 and 2001-2, 3272 children aged under 16 years with femoral fractures were admitted to hospital. The crude incidence during this period decreased from 0.33 to 0.22 femoral fractures/1000/year. Those caused by traffic accidents decreased by 43%, and by falls by 29%. The peak age-gender-specific incidence (0.91/1000/year) was in two-year-old boys, and this was 50% higher than in the next highest age-gender group. In the first year of life, the incidence in boys and girls was the same. Thereafter the rate in boys exceeded that in girls, varying from 1.6 times at 11 years to 4.7 times at 14 years. Falls accounted for 49% of the fractures, varying from 77% in one-year-olds to 26% in eight-year-old children. Traffic accidents were responsible for 26% of fractures varying from 55% in ten-year-old to 2% in one-year-old children. Maltreatment was recorded in 1.3% of all cases, and in 8.5% of children under one year. Twice as many fractures were seen in May to August than in January (winter). The rates of fractures were associated with deprivation for all age-gender groups. Fractures of the shaft accounted for 58% of all fractures, varying from 70% in three-year-old to 34% in 13-year-old children. Our findings show that there has been a decrease in the incidence of femoral fractures during the 1990s and early 2000s. Two-year-old boys had twice the rate than any other single-year age-gender group. More deprived areas had much higher rates which suggests the potential for greater prevention. A relatively low rate of maltreatment was recorded compared with that in some other studies.     

Spontaneous pneumothorax

A ten-year clinical series of 219 patients with spontaneous pneumothorax is presented with an average follow-up of 9 years. The vast majority of the patients were young men with a ruptured subpleural bleb. A slight increase in the incidence was noted in the older age groups with tuberculosis and chronic bronchitis as compared with the earlier series from the same hospital. The primary treatment was conservative in 197 and surgical in 22 cases. Recurrence of the pneumothorax occurred in 55 cases (25%). Primary conservative treatment failed in 41 cases, yielding 118 patients to operative approach. None of the patients treated by operation (plication or resection and suture of the bleb) had a later recurrence. Five re-operations were necessary: four because of a prolonged air leak after the first operation and one for bleeding. Two patients died on account of their pneumothorax, which gave a mortality of 1%. On the basis of the experience obtained, intercostal tube drainage is recommended as primary treatment; if it fails, thoracotomy seems to offer a good permanent result.     

Spontaneous pneumothorax

Spontaneous pneumothorax in the apparently healthy individual is a reasonably common occurrence. In a military hospital serving a large population in the age range most at risk for this entity, we have gained a wide experience with this problem. A review of our 10 year experience with spontaneous pneumothorax and its surgical treatment has been presented. In our series, a decreased male to female ratio was noted. This may reflect the increased incidence of female smokers. A total of 9.4 percent of our patients had complications of their tube thoracostomy treatment and an additional 10 percent required surgery for resolution of their problem. Our indications for pleural abrasion have been discussed. Pleural abrasion remains our mainstay of surgical therapy for treatment of recurrent spontaneous pneumothorax with acceptable morbidity.     

National survey of notifications of tuberculosis in England and Wales in 1988. Medical Research Council Cardiothoracic Epidemiology Group.

BACKGROUND: A survey was undertaken to determine the distribution of tuberculosis in England and Wales and, by comparison with the findings of similar surveys in 1978-9 and 1983, to study trends in the incidence of the disease by ethnic group over the decade. METHODS: The survey included all cases of tuberculosis in England and Wales newly notified to the medical officers for environmental health during the six months from 2 January to 1 July 1988. Notification rates were calculated from population estimates from the 1988 Labour Force Survey. RESULTS: Clinical details were obtained from the clinician for 2149 (99.4%) of the 2163 newly notified and previously untreated patients. Over 90% were either white (53%) or of Indian, Pakistani, or Bangladeshi ethnic origin (39%). The notification rate in the white population was 4.7/100,000/year, a decline of 7.2% per year since 1978. The rate was 134.6/100,000/year in the population of Indian ethnic origin, and 100.5/100,000/year in that of Pakistani or Bangladeshi ethnic origin, a decline of 6% a year since 1978 for the two groups combined (standardised for age, country of birth, and length of time in the UK). In all ethnic groups rates of disease were much higher in the elderly than in the young. Bacteriological results were available in 1161 (80%) of the 1443 pulmonary cases. In 939 (81%) Mycobacterium tuberculosis was cultured; 614 cases (53%) also had positive smears, of which 424 (69%) were from white patients. CONCLUSIONS: Notification rates for tuberculosis in England and Wales declined over the decade, but major differences remained between ethnic groups.     

Spontaneous pneumothorax

Spontaneous pneumothorax is usually a benign disorder caused by rupture of subpleural blebs. Treatment should provide for rapid rehabilitation. Because of a 70 to 80 per cent recurrence rate after a second or third episode, pleural abrasion should be performed to prevent further attacks. Persistent air leak, large apical blebs, initial pneumothorax in flight personnel, and the rare tension or hemopneumothorax are additional indications for an immediate pleura-obliterating procedure. The method of treatment for the initial episode in patients without the foregoing indications for operation should be geared toward safe, early, complete rehabilitation to avoid the potential danger and obvious economic hardships of conservative therapy. Simple transaxillary thoracotomy has the advantages of taking less time and causing less discomfort and minimal scarring.     

Catamenial pneumothorax

We report 3 cases of catamenial pneumothorax, with review of the literatures. Case 1: A 38-year-old female had recurrent right-sided pneumothorax in February 2001. Videothoracoscopic visualization showed multiple small fenestrations in central tendon of diaphragm. A partial diaphragmatic resection including the lesions was performed. She received hormone therapy postoperatively. Case 2: A 40-year-old female with past history of ovarian endometriosis had recurrent right-sided pneumothorax in 1993. During the operation, multiple diaphragmatic fenestrations and bullae of right middle and lower lobes were identified. The lesions were resected and postoperative hormone therapy was performed for 6 months. In 1997, right-sided pneumothorax recurred. She underwent surgical procedure due to prolonged air leakage from the right lung. During the operation, a diaphragmatic fenestration and bulla of apex of right upper lobe of the lung were visualized. Diaphragm was reefed and bulla was resected. After that, she had no recurrence of pneumothorax. Case 3: A 39-year-old female had recurrent right-sided pneumothorax in 2003. Under video-assisted thoracoscopic surgery, multiple fenestrations of central tendinous diaphragm were identified. Diaphragmatic partial resection was performed. Postoperatively, she received hormone therapy for 6 months. After hormone therapy, she suffered from recurrent pneumothorax, and underwent an operation. During the operation, she had endometriosis of visceral pleura without diaphragmatic fenestration. Once again, she received postoperative hormone therapy. Catamenial pneumothorax is a rare disease, and the definite etiology has not been clarified. A combination of both surgical and hormone therapy is useful for treatment.     

Neonatal pneumothorax

A simple method of providing under-water-seal drainage using readily available equipment is described. It enables adequate treatment of pneumothorax to be instituted with the minimum delay.     

Cathamenial pneumothorax

Cathamenial pneumothorax is a relatively low-frequency pathology (approximately 100 cases cited in the literature) characterized by recurrent pneumothorax episodes during the menstruation period. We report on a 34-year-old female patient who had recurrent pneumothorax that did not respond to chest drainage and whose presentation was directly related to the menstruation period. Our patient also had a significant clinical record for pelvic endometriosis. She underwent video-assisted thoracoscopic exploration (VATS) of the pleural cavity and dystrophic parenchymal blebs of the middle lobe were found. An atypical resection of the bollous tissue was performed and pleurodesis completed the intervention. During VATS no ectopic endometriosis foci or diaphragmatic fenestrations (widely considered as a possible cause of this clinical picture) were evidenced.
