A 41-year-old-white man with achondroplasia has been followed intermittently since age 27. During this time, he has complained of neck and back pain with limited mobility in both. Other problems have included temporomandibular joint pain, dysuria without apparent
urinary tract infection
iritis, anemia, and an elevated gamma globulin fraction. Recently he returned to the clinic complaining of rigidity of the entire spine. Radiographs showed complete fusion of the sacroiliac joints and fusion of the cervical vertebral bodies and apophyseal joints, consistent with
ankylosing spondylitis
. He was found to be HLA B-27 positive. This case illustrates the importance of considering other diseases whenever atypical orthopedic problems arise in patients with a bone dysplasia.

146 men with rheumatoid factor-negative (sero-negative) arthritis, i.e., 97 patients with
ankylosing spondylitis
, 36 patients with Reiter's syndrome, and 13 patients with reactive arthritis, were examined for infections of the urogenital tract by following recently established criteria. 74 patients (50.7%) had infections of the male adnexes: 3 patients suffered from balanitis, 14 patients from urethritis, 49 patients from prostatitis, 1 patient from epididymitis, and 7 patients from
urinary tract infection
. Balanitis and urethritis were almost exclusively associated with Reiter's syndrome. In 37 of 97 patients with
ankylosing spondylitis
, a urogenital tract infection, mainly a prostatitis (31 patients), was detected. The microorganisms isolated most frequently from patients suffering from urethritis and prostatitis, were Chlamydia trachomatis and Ureaplasma urealyticum.

The objective of the study was to investigate potential triggering events for the onset of
ankylosing spondylitis
(AS). A large retrospective population survey of 1,080 AS patients was carried out by multi-faceted questionnaire. A nested case-control study compared the cohort to 102 patients with lumbar disc prolapse. Participants with AS had a mean age of 49.8 years, mean age of disease onset was 25.2 years and 63% of the cohort were male. Seventy-nine per cent knew they were human leucocyte antigen (HLA)-B27-positive, and a further 12.5% were unaware of their HLA-B27 status. Infections were relatively common in the 3 months leading to the first symptoms, 4.6% reporting gastrointestinal infection, 2.5% reporting
urinary tract infection
and 2.6% respiratory infection. Five per cent reported heavy physical activity in the 3 months prior to the onset of symptoms, 4.2% emotional stressors and 3.1% work stressors. Injury and surgery were less commonly reported (1.7 and 0.7%, respectively). Pregnancy was reported by 7.4% of the female participants. When the 12 months leading up to the first symptoms was compared to the 12 months previous to that, work stressors (OR 1.5), and pregnancy (OR 2.5) infection (OR 1.5 to 1.8) were significantly more common closer to disease onset. Infection and work stressors are potential triggers for the onset of AS; however, low rates suggest they are only a small part of the environmental milieu that combines with a genetic predisposition to cause the development of this chronic inflammatory disease.
