Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is typically characterized by episodic fever, myalgia, skin rash, conjunctivitis, and abdominal cramps. Recently, mutations in the TNFRSF1A gene on chromosome 12p13 encoding tumor necrosis factor receptor type 1 have been linked to this autoinflammatory syndrome. We report the case of a 29-year-old white woman who experienced periodic inflammatory manifestations with fever up to 40 degrees C, leukocytosis, and elevation of C-reactive protein level (>100 mg/L) in conjunction with acute peritonitis of unknown origin since the age of 19 years. The patient had undergone 2 laparotomies with appendectomy and left hemicolectomy. Familial Mediterranean fever was excluded by sequencing of the MEFV gene. In view of the possibility of TRAPS, sequence analysis of the TNFRSF1A gene was also performed. The patient carried a novel T-->G substitution in exon 3, leading to the replacement of phenylalanine by valine at amino acid position 60 (F60V), as well as the common R92Q low-penetrance mutation, encoded by exon 4. Upon the next flare, the patient started corticosteroid therapy, resulting in complete relief and normalization of elevated C-reactive protein levels. To the best of our knowledge, we report the first case of compound heterozygosity for 2 TNFRSF1A gene mutations, including a novel one that causes a severe form of TRAPS that responds to anti-inflammatory treatment. A history of recurrent sterile peritonitis should prompt genotyping for periodic fever syndromes.

Arsenic is a toxicant that has no dose threshold below which exposures are not harmful. Here I report a curious association of chronic homeopathic arsenic ingestion with nonspecific symptoms in a Swiss teenager. For about 4 years she had taken globules of a freely purchasable homeopathic remedy containing inorganic arsenic (iAs), infinitesimally diluted to D6 (average arsenic content per single globule: 0.85 ± 0.08 ng). In the previous 7 months she had taken 20 to 50 globules daily (average 30 ng arsenic daily). She complained of nausea, stomach and abdominal cramps, diarrhoea and flatulence, headache, dizziness, anxiety, difficulty concentrating, insomnia, snoring, leg cramps and fatigue, loss of appetite, increased thirst and sweating, reduced diuresis, weight gain, paleness and coolness of both hands with a furry feeling of the hands, eczema of the hands, arms and legs, conjunctivitis and irregular menstruation. The physical and laboratory examinations showed a body mass index of 30 kg/m2, acne vulgaris, bilateral spotted leukonychia, eczema of hands, arms and legs, non-pitting oedema of the legs, elevated plasma alkaline phosphatase activity, folate deficiency and severe vitamin D3 insufficiency. The arsenic concentration in her blood was <0.013 µmol/l, and arsenic was undetectable in her scalp hair. The total iAs concentration was 116 nmol/l in the morning urine and 47 nmol/l in the afternoon urine. The urinary arsenic concentration decreased and the patient’s complaints improved upon interruption of the arsenic globules, vitamin D3, thiamine and folic acid supplementation, and symptomatic therapy. It is concluded that an avoidable toxicant such as inorganic arsenic, for which no scientific safe dose threshold exists, should be avoided and not be found in over-the-counter medications.
