ABSTRACT
Inclusion body myositis (IBM), the most common inflammatory myopathy in the elderly, is often resistant to various forms of therapy. Placebo-controlled treatment trials with high dose intravenous immunoglobulins (IVIG) have shown disease amelioration in some but not all patients. Here, we present the informative case of a 70-year-old woman with diagnosed inclusion body myositis that showed progressive muscle weakness without treatment and following immuno-suppressive treatment with corticosteroids and azathioprine. A trial with low-dose intravenous immunoglobulins was started at that time. The patient responded rapidly to low dose IVIG treatment with amelioration of muscle strength and normalization of CK serum activities. Our results demonstrate that IBM patients may respond to low-dose IVIG treatment which has important clinical and economic consequences.

Adult-onset Henoch-Schonlein purpura (HSP) tends to become chronic-relapsing, yet rarely leads to organ impairment, e.g. due to chronic glomerulonephritis. Bed rest, compression and nonsteroidal anti-inflammatory drugs are usually sufficient to control the active phases. We report 2 cases of adult HSP with an unusually severe evolution. One patient required intensive-care treatment for hypovolemic shock caused by hemorrhagic pancolitis; the other had progressive and extremely extensive vasculitic leg ulcers. Both were refractory to common immunosuppression with systemic corticosteroids (oral and pulse) and additive steroid-sparing immunosuppressive drugs. Only after the introduction of plasmapheresis did both patients show a dramatic improvement in the disease, with rapid and almost complete healing. Plasmapheresis is a rarely used therapeutic tool in the treatment of severe HSP, but the growing literature on its highly beneficial effect underlines its potential usefulness.

BACKGROUND: The Savary-Miller, the Los Angeles, and the MUSE (metaplasia, ulcer, stricture, erosion) scoring systems have been developed to assess esophageal lesions related to GERD. Interobserver agreement for these systems was compared, with particular reference to the experience of the endoscopist. METHODS: By using videoendoscopes, videotapes were made of the gastroesophageal junction of 60 patients who presented with symptoms suggestive of GERD. The Savary-Miller, the Los Angeles, and the MUSE systems were used to score all video clips by 9 endoscopists who were subgrouped by level of experience (3 levels, 3 endoscopists per level). Agreement was assessed by using weighted kappa statistics (kappa). RESULTS: The Savary-Miller scoring system revealed moderate agreement for the experienced group (kappa=0.41) but performed poorly when applied by inexperienced raters (kappa=0.16). The Los Angeles system was most reproducible in all subgroups, irrespective of the level of experience (kappa=0.49 to 0.65). The MUSE scoring system was highly similar to the Los Angeles scoring system with respect to erosions and, in addition, allowed assessment of complications of GERD. CONCLUSIONS: The Los Angeles and the MUSE scoring systems are most reliable for the assessment of erosions caused by GERD. Because of low reliability, use of the Savary-Miller scoring system is not recommended. For all scoring systems, interobserver agreement varies with the level of experience in the performance of upper endoscopy.

High resolution 1H NMR spectroscopy is a powerful method for qualitative and quantitative analysis of the highly viscous human cervical mucus (CM). Up to 23 compounds could be identified in this study and can be observed in the 1H NMR spectra of native mucus without the need of any complicated preparative chemistry. Storage conditions could be excluded as a possible reason for variations observed between different samples. pH values decreased after freezing and storing at 253 K. For NMR studies, lyophilization proved to be most useful, allowing the determination of the water content, replacement of H2O by D2O, and most importantly, absolute quantification of low molecular mass compounds. In a small collective of women the concentrations of some of the small constituents of the CM are strongly correlated; an example is the mutual positive correlation of taurine, citrate and creatinine. In conclusion, high resolution 1H NMR spectroscopy is a valid method to investigate mucus composition and to determine absolute concentrations of low molecular mass compounds in CM.
