Introduction: In recent years, childhood obesity and obstructive sleep apnea (OSA) during childhood have been defined as a Public Health problem, becoming a challenge for professionals at the same time. Both entities are considered to have a familial and genetic association. Methodology: Prospective study in children between 3 and 14 years old, referred for clinical suspicion of OSA to the "Multidisciplinary Sleep Unit". The study groups were divided according to whether or not they presented obesity and whether or not they presented OSA. Objective: Describe the characteristics of the personal and family history in each study group. Results: The obese group had a median birth weight percentile of 69 and the non-obese group of 35.5 (p=0.241). Regarding the family history, the obese father and mother are more obese than the non-obese (p=0.005, p=0.032). In family history of OSA between children with and without OSA, we found no differences, fathers (p=0.741), mothers (p=0.453), siblings (p=0.242). Other personal history studied and associated with OSA, we did not find differences between OSA and non-OSA either. Conclusion: Our study reveals the importance of a history of obesity from early stages of life, and the implication that a family member is also obese. We did not find a family association of OSA in our series. A good clinical history can help us to detect numerous personal and family factors that will condition children's health.

Starch is one of the most widely used natural biopolymers in the cosmetic industry, because it is an environmentally friendly, abundant, and inexpensive product. However, its structure must be modified for greater use of its physical, chemical, and mechanical characteristics. There are currently more than 15,000 publications in which starches of different plant species are related to some chemical modification by esterification reactions with Acetic Anhydride, Octenyl Succinic Anhydride (OSA) and Dodecenyl Succinic Anhydride (DDSA), according to the search carried out in different databases until July 2020. This confirms the extensive use of modified starches that can be used as excipients in different products of great utility to humanity. [ABSTRACT FROM AUTHOR]

The accepted standard method for titration actually accepted is the conventional polysomnography. It consumes time, qualified personnel and has a high operational cost. Objective: To evaluate the auto adjustable CPAP use for CPAP titration in patients with diagnosis of moderate to severe Obstructive Sleep Apnea (OSA). Material and methods: We report 54 patients with the diagnosis of OSA done by polysomnography (6) and respiratory polygraphy (48). We used the Autoset T (Resmed®) autoadjustable system for titration. All patients received during an office interview the instructions about how to use the equipment before they were taken it home. If results of the first test were not satisfactory, the patient would take it home for a second test. Results: 54 studies were done, one for each patient. In the first test, 8 studies (15%) failed, so they took the equipment home once again. Finally, only in 2 patients (3.7%) the titration failed and they needed a conventional titration with polysomnography. The final pressure to be programmed to the CPAP was defined according to the graphic's visual reading. At the moment we finished the data base, 44 (81%) patients were using the CPAP regularly. Conclusions: We consider that non-conventional titration based on the visual reading of auto adjustable CPAP records is an useful, simple, very cheap CPAP titration method in our country.

Objective: We report series of patients with Obstructive Sleep Apnea (OSA) diagnosed with a respiratory polygraph (RP). Materials and methods: We present the results of 53 RPs made between January 2005 and October 2006. All patients had the suspicions of sleep breathing disorders. We used the polygraph BREAS SC-20 that we validated in a previous report. The test was implemented through the night in patient's home without technical supervision. In 32 (60%) cases the device was installed in the physician's office and the rest at patient's home. Results: We analyzed 53 RPs, made in the same number of patients. The acquisition failed in 6 (11%) and the tests were repeated in a second opportunity with good results. Registry time was 7.7±1.1 [5.5-10.7] hours, apnea-hipopnea Index (AHI) 35.5±20 [0-82], percentage of registry time with SatO2 below 90% (T90) 9.8±15.2 [0-62] % and maximum oxygen desaturation 73±14.8 [38-91] %. The diagnoses were: OSA 46 (86%), central apnea with periodic Cheyne Stokes pattern 3 (6%), primary snore 2 (4%) and normal test 2 (4%). The procedure was well tolerated and there were not related side effects. Conclusions: According to our results, we consider that the BREAS SC-20 system is a useful, practical and economic tool for the diagnosis of OSA; under the supervision of sleep breathing disorders trained physicians.
