UNLABELLED: The trend of the cesarean section in three setting of the Instituto Mexicano del Seguro Social (IMSS); the local: Hospital Gineco-pediátrico No. 2, in Los Mochis, Sinaloa, was determined the state's: included all of the medical units of IMSS in the state of Sinaloa and the national, which included all of the medical units of IMSS in the country. It was an analytic, retrospective study medical units of IMSS cesarean deliveries in the three setting of IMSS, from 1981 to 1995. SOURCE OF INFORMATION: State Committee of the Information Processing of the State of Sinaloa retrospective measurement of the total of deliveries and cesarean sections to calculate frequency of this event for each year and setting. Lineal regress analysis was made to determine trend of cesarean sections and correlation coefficient (r). RESULTS: Local frequency: 24.3 +/- 6.1%, range 14.7-33.6%; state's: 21.6 +/- 5.8%, range 13.2-30.3, national 24.4 +/- 5.5%, range 16.6-33.6; r per setting: local: +0.98 (Cl 95% 0.8793 = 0.99), state's +0.99 (Cl 95% 0.94-0.99) and national: +0.99 (Cl 95% 0.95-1.0). Positive trend in performance of cesarean sections in the three setting during the period of study; if no intervention on the matter at IMSS, the national trend will reach 39.2% in the 2000 year, state's: 37.4% and the local: 39.4%.

Pesticide poisoning in Mexican seasonal farm workers.

The authors investigated pesticide poisoning in 200 seasonal farm workers employed in a small area in northwest Mexico. Of these workers, 45% were migrants from southern Mexico, and 70% were men. Most were about 20 years old; 59% could read at the third-grade level. Few had received information about pesticides; 30% did not wear personal protective gear; and 20% had experienced acute pesticide poisoning at least once during the season investigated.

[Vasovagal syncope. Management with propanthelin bromide]. / Síncope vagotónico. Manejo con bromuro de propantelina.

OBJECTIVE: To study propanthelin bromide efficacy in preventing vasovagal syncope relapse. SETTING: HGZ No. 3 IMSS, Mazatlán, Sinaloa, México, from 1992 to 1995. PATIENTS: 10 patients with vasovagal syncope were selected from 41 syncope patients. DESIGN: Prospective longitudinal. MEASURES: clinical charts, neurologic and cardiologic evaluation, electrocardiogram, electroencephalogram, C.A.T., Holter, stress test and chest X rays were made. In 10 patients, 15 to 30 mg of propanthelin bromide thrice a day were administered, 12 month survey on was made measured. RESULTS: Of the 10 patients, 7 were women mean age 18 years. In 9 of them no recurrence was evident abandoned 1 treatment, 4 had side effects. CONCLUSIONS: Propanthelin bromide decreases vasovagal syncope episodes with few side effects.

[Perinatal conditions of newborns of adolescent mothers in the state of Sinaloa, Mexico]. / Condiciones perinatales en recién nacidos de madres adolescentes del estado de Sinaloa, México.

UNLABELLED: The objective was to compare perinatal conditions of newborns and obstetric complications between a group of adolescent mothers and one of adult mothers. It is a retrolective comparative survey, at the General Hospital "Bernardo J. Gastelum" SSA and General Hospital IMSS, Sinaloa, Mexico. PATIENTS: 10634 clinical records of patients in labour at obstetric unit from 1990 to 1994. A randomized sample of 215 adolescent pregnant patients and 215 adult pregnant patients were selected and the following data were analysed regarding to the mother: age, pregnancy outcome and obstetric complications; in regard to the newborn: gender, weight, height, cefalic circumference and Apgar score. The mean adolescent mother's age was 16 years, and 25 in adult mothers; mean adolescent mother newborn birthweight was 3.297 SD 0.414 kg. and in adult mothers was 3.393 SD 0.591 kg. (p = 0.09), adolescent mothers newborns with Apgar score less than 7 at first minute was 20% and 5% for adult mothers newborns. Statistically significant difference was observed (p = 0.02). There were not statistically significant differences between the groups in obstetric outcome and complications, birthweight. It was concluded that pregnancy in adolescence it's not a risk factor for the mother and the newborn.

[Cervical labor induction with prostaglandin E2 in patients with fetal death]. / Maduración cervical con prostaglandina E2 en pacientes con feto muerto.

The objective was to compare the effectiveness and efficacy of prostaglandin E2 (prepidil gel) plus oxitocin with that of intravenous oxitocin in the treatment of delivery induction in patients complicated with fetal death. Fifteen patients received prepidil gel plus oxitocin and 15 patients oxitocin. In the treatment group only one dosage of 0.5 ng in 2 ml of prepidil gel was administered intracervically and simultaneously oxitocin by intravenous infusion, dosage was increased 2 mUI/min every 30 minutes. In the control group only intravenous oxitocin was administered at the same dosage. The mean duration in hours of delivery in the treatment group was 13.1 +/- h and in the control group was 30.9 +/- 9.1 h. There were statistically significant differences between the groups in reduction of delivery duration (p = 0.0007). It is concluded that prostaglandin E2 plus oxitocin provide better short-term outcomes than oxitocine treatment and gave more short periods of labor in patients with fetal death.

[Prevalence of digestive system cancer patients covered by the Mexican Institute of Social Security of the State of Sinaloa, Mexico]. / Prevalencia de cáncer del aparato digestivo en población derechohabiente del IMSS en el Estado de Sinaloa, México.

OBJECTIVE: To determine the frequency of malignant neoplasia of the digestive tract in patients seen at the IMSS concentration hospital in Culiacán, Sinaloa, México. METHODS: From 32,097 histopathologic studies performed at No. 1 Regional General Hospital Pathology Department in Culiacán, Sinaloa, 406 were identified as digestive tract malignant neoplasia (DTMN); patient's age and gender were analyzed as well as involvement site and histological type. Benign and metastasic neoplasias were excluded. RESULTS: DTMN prevalence: 1.26%; more affected: 60-69 years; male predominance (66%), p < 0.0001. As a whole, 47.2% of the studies reported stomach cancer; colorectal cancer: 17.5%; gall bladder and bile duct cancer; 8.4%; liver cancer: 8.1%; the remainder were located in other sites. DTMN rate by histologic type were similar to other concentration hospitals of the country. CONCLUSIONS: DTMN has an outstanding magnitude in IMSS Sinaloa patients if other hospital registrations are considered. There are possible regional factors that may contribute to this behavior.
