18p deletion syndrome is a rare disorder which is accompanied with mental retardation, facial abnormalities and short stature. Dystonic findings are rarely seen and only 12 cases have been reported in the literature until now. We report here a 26 year old female complaining of spasms on her trunk and limb muscles. Genetic investigation revealed 18p deletion.

BACKGROUNDBoth early repolarization and altered heart rate profile are associated with sudden death. In this study, we aimed to demonstrate an association between early repolarization and heart rate profile during exercise.

METHODSA total of 84 subjects were included in the study. Comparable 44 subjects with early repolarization and 40 subjects with normal electrocardiogram underwent exercise stress testing. Resting heart rate, maximum heart rate, heart rate increment and decrement were analyzed.

RESULTSBoth groups were comparable for baseline characteristics including resting heart rate. Maximum heart rate, heart rate increment and heart rate decrement of the subjects in early repolarization group had significantly decreased maximum heart rate, heart rate increment and heart rate decrement compared to control group (all P < 0.05). The lower heart rate increment (< 106 beats/min) and heart rate decrement (< 95 beats/min) were significantly associated with the presence of early repolarization. After adjustment for age and sex, the multiple-adjusted OR of the risk of presence of early repolarization was 2.98 (95%CI 1.21-7.34) (P = 0.018) and 7.73 (95%CI 2.84-21.03) (P < 0.001) for the lower heart rate increment and heart rate decrement compared to higher levels, respectively.

CONCLUSIONSSubjects with early repolarization have altered heart rate profile during exercise compared to control subjects. This can be related to sudden death.

Anaphylaxis have been documented as adverse effects of ciprofloxacin, ofloxacin, norfloxacin, levofloxacin, and moxifloxacin. However resistant and biphasic anaphlylactic reactions to gemifloxacin have not been reported to date. Management of severe anaphylaxis in the elderly can be complicated by concurrent medications such as beta (β) adrenergic, alpha (α) adrenergic blockers and angiotensin-converting enzyme (ACE) inhibitors. We report here in the case of a 60-year-old male who was taking on ACE inhibitor, α and β blockers and experienced a severe, resistant and biphasic anaphlylactic reaction to gemifloxacin mesylate.
