Near miss cases were frequent and related to delays in reaching and receiving adequate care.
As demonstrated for leishmaniasis surveillance in Argentina (12 ), inconsistencies among provincial, national, and Chagas surveillance reports of congenital cases were frequent and led to substantial underreporting.
This explains the reason why the baseline-level LOH cases are frequent in diffuse-type gastric cancers in young-aged patients [ 3, 4, 7].
However, exceptional cases are frequent, since 80% of high-grade adenomas progress to adenocarcinomas, whereas 15% of low-grade adenomas progress to high-grade adenomas or adenocarcinomas (Lauwers and Riddell, 1999).
The actual rhythm on the 12-lead ECG in the false-positive cases was frequent premature atrial or ventricular complexes with an irregular coupling interval in three patients, sinus arrhythmia in one patient, and atrial flutter with an irregular ventricular response in two patients.
Transmission of this type, although artificial in our case, is frequent in natural transmission of virus and other pathogens and the interaction between the probability of appearance of compensatory and reversion mutations, clonal interference and bottlenecks are likely to play a substantial role in the low reversibility at the sequence level.
In sporadic RST, the simultaneous loss of more than one APM molecule per case was frequent.
However, the adjustment used the maximum likelihood ratio based on the asymptotic assumption, which cannot be verified in our case due to the small number of cases, which is frequent in epidemiology.
These results show that cross-clustering of cases of astrocytoma with cases of ependymoma is frequent, in addition to clustering pairs of astrocytoma or ependymoma alone.
