RESUMEN
Environmental samples collected in Brindisi (Italy) by a Hirst-type trap and in Lecce (Italy) by a PM10 sampler were analysed by optical microscopy and DNA-metabarcoding, respectively, to identify airborne pollen and perform an exploratory study, highlighting the benefits and limits of both sampling/detection systems. The Hirst-type trap/optical-microscopy system allowed detecting pollen on average over the full bloom season, since whole pollen grains, whose diameter vary within 10-100 µm, are required for morphological detection with optical microscopy. Conversely, pollen fragments with an aerodynamic diameter ≤10 µm were collected in Lecce by the PM10 sampler. Pollen grains and fragments are spread worldwide by wind/atmospheric turbulences and can age in the atmosphere, but aerial dispersal, aging, and long-range transport of pollen fragments are favoured over those of whole pollen grains because of their smaller size. Twenty-four Streptophyta families were detected in Lecce throughout the sampling year, but only nine out of them were in common with the 21 pollen families identified in Brindisi. Meteorological parameters and advection patterns were rather similar at both study sites, being only 37 km apart in a beeline, but their impact on the sample taxonomic structure was different, likely for the different pollen sampling/detection systems used in the two monitoring areas.

Objective To investigate the clinical significance of generalized epilepsy with febrile seizures plus(GEFS+ ). Methods The data of one family with GEFS+ were retrospectively analyzed by studying clinical manifestations, physical examinations, electroencephalogram(EEG), 24 hours dynamic EEG monitoring, et al. Some of the patients were examined by CT. Results Ⅳ 12, her chief complaints when admitted to hospital were frequent spasm for 3 days. She began to appear febrile seizures (FS) from 8 months after birth, and frequent generalized tonic - clonic FS appeared during that time. There were 36 people in 5 generations of the family including 14 patients (8 males and 6 females) ,aged from 4 years and 5 months to 82 years. FS presented in 8 cases (Ⅱ 2, Ⅲ1, Ⅲ4, Ⅲ6, Ⅳ1, Ⅳ11, Ⅳ17, Ⅴ2),febrile seizures plus(FS +) in 4 cases ( Ⅳ2, Ⅳ12, Ⅳ13, Ⅳ14), ES + and absence seizures in 1 case ( Ⅴ1 ), uncertain type in 1 case (Ⅰ2). The results of EEG indicated that 12 cases were normal and 4 cases with FS+ and 1 case with absence seizures had epileptic discharges. Apart form Ⅳ13, Ⅳ14 who were treated with magnesium valproate, the dosage for the other patients decreased, or medicine terminated or without medicine, and all the patients had no recurrence of seizures. The intelligence, movement development and neurological examinations of the family were all normal. Head CT scan of 3 cases were normal. Conclusions GEFS+ is autosomal dominant inheritance disease with conspicuous genetic heterogeneity and phenotypic heterogeneity. The apprehension of GEFS+ plays an important role in diagnosis and differential diagnosis of epilepsy in childhood.
RESUMEN
Objective To analyse the follow-up of one family with generalized epilepsies with febrile seizures plus (GEFS +).Methods We conducted a family with GEFS + by sexs,ages, seizure manifestation,electroencephalogram (EEG),and so on.Results There were 36 people in 5 generations of the family in all,including 14 patients(8 cases were male and 16 cases were female).Their ages were from 4 years and 5 months to 8 years.There were 8 cases febrile seizures (FS),4 cases with FS + and 1 case with FS + and absence seizures in 13 patients except 1 case without adequate knowledge.The Results of ECG indicted that 12 cases were normaland 4 cases with FS + and 1 case with absence seizures had epileptic discharges.Conclusions GEFS + is a common kind of inherited epilepsic syndrome and occur in childhood.So it is greatly important for epileptic children to know GEFS +
