  Dear editor: We read with great interest the paper by Bass et al[1] on the mnemonics of cholelithiatis in the november 2013 issue of PMJ. The authors conclude that Family History should be considered as a predictive factor. We would like to share our own experience on this matter.

  Dear editor: We read with great interest the paper by Bass et al[1] on the mnemonics of cholelithiatis in the november 2013 issue of PMJ. The authors conclude that Family History should be considered as a predictive factor. We would like to share our own experience on this matter. We collected 173 consecutive patients diagnosed of cholelithiasis, inpatients and ambulatory care patients, during January and February, 2014. In all cases the diagnosis of biliary stones was established by an abdominal ultrasound or surgical confirmation. Patients were interviewed on sex, age, parity, family history of cholelitiasis. Skin fair and the body mass index were determined by our team. Parity was considered positive when there was at least one born child. Fat was considered as such with a BMI of 25 or more. A family history was considered positive if a first degree relative had been diagnosed or had surgery for cholelithiasis. A total of 173 patients were included; with an age average of 50,16 +- 14 years and 79.8 % female. The frequency of each of the 6 Fs studied are a)Fertility:95.7% ; b)Female: 97.8% ; c)Forty: 75.1% ; d)Fat: 69.9% ; e)Family History: 46.2%, f) Fair: 4% (*Fertility: only females ; fat: excluded 69 patients with surgical confirmation) According to our results, fertility, female gender, age above 40 years and an increased BMI were the 4 Fs that best predicted cholelithiasis. In Peru, and particularly in Callao, where predominant skin phototypes are III, IV and V and fair skin is very rarely found, the F of fair, should be disregarded[2]. Therefore, we agree with the authors that Family History should also be considered as a predictive factor. Conflict of Interest: None declared REFERENCES 1.
