[Analysis of the epidemiological profile of the indigenous community of Hueyapan, Morelos]

BACKGROUND

The epidemiological transition is a phenomenon that has had a different impact between urban and rural settings. The WHO points out that the population with the lowest socioeconomic status is the most adversely affected for the unequal distribution of resources, indigenous people are a part of this population.

OBJECTIVE

To analyze the epidemiological profile of the indigenous people of Hueyapan, Morelos during the months of March to June 2017.

METHODS

A cross-sectional epidemiological study was carried out in the indigenous community of Hueyapan, belonging to the municipality of Morelos, in 2017. A sample of 338 households was calculated; as inclusion criteria, those dwellings where the age of residence in Hueyapan was equal to or greater than four years were taken; a systematic sampling was carried out every three households, in addition, Mexico's INEGI and Health Department databases were analyzed from 2011 to 2015.

RESULTS

In relation to morbidity, an upward trend was found in the crude rate, from 119.7 per 1,000 in 2011 to 270.7 per 1000 in 2015, among the most prevalent diseases in those years, infectious diseases were identified as major and the appearance of noncommunicable diseases began to be observed. In relation to mortality, a linear trend was observed in the crude rate of 5.7 per 1000 in 2011 to 6.6 per 1000 in 2015.

CONCLUSIONS

The epidemiological profile of Hueyapan coincides with a process of epidemiological transition where there is a double burden of disease. This suggests a challenge for the public health area that should be addressed from the creation of health strategies, programs and policies aimed at this population from an intercultural approach.

Incidence of Escherichia coli intestinal infections, active component, U.S. Armed Forces, 2007-2016

During 2007-2016, there were 290 incident cases of Escherichia coli infection among active component service members, with an overall crude incidence rate of 2.3 cases per 100,000 person-years (p-yrs). Subgroup-specific rates were higher among service members aged 50 years or older and those aged 25-29 years than those in other age groups. Compared to their respective counterparts, females, non-Hispanic white service members, members of the Air Force, and service members in healthcare occupations had the highest rates of E. coli infection. Crude overall incidence rates were highest among senior enlisted service members and junior officers, compared to those in other ranks/grades. Annual incidence rates of E. coli infection among active component service members peaked in 2011 (3.4 cases per 100,000 p-yrs) and in 2016 (4.7 cases per 100,000 p-yrs) but otherwise were relatively stable. The monthly distribution of the cumulative number of incident cases of infections during the 10-year period showed a modest pattern of seasonality. During 2008-2016, a total of 14 incident cases of E. coli infection were identified among active component service members during deployments. Standard measures for the prevention of intestinal E. coli infection are reviewed.

An analysis of intestinal transplant in the United States

We performed a retrospective analysis of intestinal transplant patients from United States transplant centers using The Organ Procurement and Transplantation Network/United Network of Organ Sharing (OPTN/UNOS) registry. A total of 2164 intestinal transplants were performed in the United States between 1990 and the end of 2011 and were reported to UNOS. Gender, ethnicity, age at transplant, and original disease had little impact on intestinal allograft survival. We found that a shift in the type of transplant operation [intestine alone, intestine plus liver (I+L), or intestine plus liver and pancreas (I+L+P)] away from I+L, starting in 2005, led to better outcomes. Transplants including the stomach had significantly worse graft survival, and often were performed with the I+L+P method. Even though the outcomes of co-transplant of stomach methods, especially the I+L+P method were shown not to be favorable, in reality, the number of patients receiving the operation is still increasing. Despite the overall improvement in graft survival for intestinal transplants over the last 2 decades, within the 2 decades there is a different story. Graft survival after 2005 compared to seven years before 2005 has not improved. Going forward, there is still significant room for improvement in intestinal transplantation. Based on the improvements over the past 2 decades, there is hope that in the next 2 decades, intestinal transplant will reach the success of renal, cardiac, and liver transplantation.

Reversal of Hartmann's procedure: experience in an Asian population

INTRODUCTION

With improvements in surgical techniques, instrumentation and perioperative care, Hartmann's procedure is now less frequently performed. Restoration of intestinal continuity after Hartmann's procedure has traditionally been viewed to be technically demanding and associated with significant morbidity and mortality. This is a study of outcomes after the reversal of Hartmann's procedure in an Asian population.

METHODS

A prospectively collected database showed that 255 patients had undergone Hartmann's procedure from October 1989 to October 2005. Patients who subsequently underwent Hartmann's reversal were identified and their records reviewed retrospectively.

RESULTS

Hartmann's reversal was attempted in 49 patients. The most common indication for Hartmann's procedure was colorectal carcinoma (49.0%). The median interval between resection and reversal was 23 weeks. Reversal was successful in 46 (93.9%) patients, with 79.6% experiencing no intraoperative complications. Failure of reversal was significantly associated with prior radiotherapy to the pelvis (p-value = 0.007). Anastomotic leak rates and re-bleeding rates were both 0.0%. 79.6% of patients made an uneventful recovery with no postoperative complications. There was no significant increase in the complication rate in older patients or patients with higher American Society of Anesthesiologists status. The overall incidence of 30-day morbidity and mortality was 20.4% and 0.0%, respectively.

CONCLUSION

In our population, Hartmann's procedure is more commonly performed for colorectal cancer rather than for diverticular disease, resulting in lower rates of stoma reversal. Hartmann's reversal could be performed with acceptable morbidity and minimal mortality, although prior radiotherapy and shorter rectal stump may pose challenges during reversal surgery.

Severe erosive lesions in the digestive tract of patients with Henoch-Schönlein Purpura (HSP) and its impact on prognosis - presentation of two cases and statistical review of adult-onset Japanese HSP

INTRODUCTION

Although many pediatric patients with Henoch-Schönlein Purpura (HSP) recover spontaneously, disease activity in adult patients often cannot be controlled by treatment.

PURPOSE

To assess the specific signs not formerly considered to be those of uncontrollable adult HSP patients.

PATIENTS AND METHODS

Clinical records of 2 adult patients who died during HSP were reviewed and previous reports on HSP were consulted.

RESULTS

Both patients had lesions in the digestive tract diagnosed as hemorrhagic erosion in the small intestine and colon. They were elderly and showed renal dysfunction. They died from severe infection after potent immunosuppressive treatment. A univariate analysis showed that age of over 60 years, severe renal symptoms (nephrotic syndrome and/or end-stage renal failure), Birmingham Vasculitis Activity Score (BVAS) of more than 18 points, massive immunosuppression and melena had significantly higher prevalence among patients who died. Multivariate statistical analysis with theoretical quantification analysis II revealed that age of over 60 and severe renal symptoms (nephrotic syndrome and/or end-stage renal failure) contributed to poor prognosis. The presence of melena did not contribute to poor prognosis despite results of the univariate analysis and our clinical impressions.

DISCUSSION

In multivariate statistical analysis, melena was selected as a sign of severe erosive lesions in the digestive tract because some of the patients were not examined by fiberscopy. Melena is caused by various lesions in the digestive tract and each of them has different effects on prognosis.

CONCLUSION

Elderly HSP patients with severe renal impairment should be carefully treated. Examination of the digestive tract by fiberscopy is recommended when melena is observed in these patients.

Intestinal parasitic infection in operation Solomon immigrants

Previous studies have documented a high infection rate of intestinal parasites in Ethiopian immigrants to Israel. As a result, current treatment recommendations are for mass treatment without prior screening tests. However, the group of 15,400 Ethiopian immigrants who arrived in Israel in May 1991 (Operation Solomon) represents a somewhat different population from those who had immigrated earlier. The 1991 immigrants had spent 9-12 months in Addis Ababa before their evacuation; the conditions there, together with the provision of medical care, may have resulted in lower infection rates for intestinal parasites. The purpose of this study was to determine the prevalence of intestinal parasites in these recent immigrants to assess whether mass treatment would still be appropriate. Random stool specimens were obtained from 80 residents of a population of 650 Ethiopian immigrants who were cared for at a Jerusalem clinic. Specimens were examined at the Ministry of Health Laboratory. Of the 80 specimens 45 had sufficient quantity of stool to perform the standard Richie concentration method. Pooling results from all 80 individuals revealed 60 (75.0%) positive specimens, 53 (66.3%) with at least one pathogenic parasite, and 21 (26.3%) with multiple pathogenic parasites. These data provide the first systematic information on intestinal parasitosis in immigrants from Operation Solomon and suggest that mass treatment in this group is appropriate.

Intestinal protozoan infections in Malaysia

Intestinal protozoa are found in all communities in Malaysia and among all ethnic groups. Prevalence of intestinal protozoa is not affected by ethnicity but by living conditions. Communities with both basic amenities of safe water supply and proper toilets have lower prevalence than those with one or none of the amenity. Cryptosporidium is an important intestinal protozoon in Malaysia and should be included in future field and laboratory studies and also in laboratory diagnosis for pathogens. Much interest will be centered on Blastocystis hominis in future studies in view that it may be a cause of diarrhea.
