ABSTRACT

INTRODUCTION

The professional practice of pediatric gastroenterology arose in Cuba as an expression of the specialty’s development internationally and Cuba’s new strategies in public health, and in response to national needs for health care expertise in digestive diseases of infants, older children and adolescents.

OBJECTIVES

Describe the history of pediatric gastroenterology’s development in Cuba since its inception at the National Gastroenterology Institute in the early 1970s, its contributions, and efforts to extend it to pediatric hospitals throughout Cuba.

EVIDENCE ACQUISITION

This is a historical review based on document analysis. Institutional sources from the National Gastroenterology Institute and Ministry of Public Health were reviewed, as well as international and national literature on the history of pediatric gastroenterology and unpublished texts since its emergence in 1972.

DEVELOPMENT

Although pediatric gastroenterology has not been formally recognized as a medical specialty in Cuba, there have been important achievements in establishing a network of specialized health care services for digestive diseases of children and adolescents. Gastrointestinal endoscopy and other auxiliary diagnostic modalities have been introduced for children and play a major role in clinical trials and research. This article describes the international context that promoted the specialty’s development in Cuba. Reference is made to specialized training from its initial stages in 1972, its consolidation as an emerging discipline in Cuban medicine, and its diffusion in Latin American and Caribbean countries. Professional development and specialized training to meet health human resource needs in pediatric hospitals are described, as well as Cuban participation in the Latin American Society for Pediatric Gastroenterology, Hepatology and Nutrition. National and international milestones, publications, awards and recognitions that indicate advances despite difficulties are also presented.

CONCLUSIONS

Since 1972, there have been major strides in the development of pediatric gastroenterology practice in Cuba. The establishment of a national network of specialized services in pediatric hospitals throughout Cuba has provided quality health care for digestive diseases of childhood. Pediatric gastroenterology’s development and achievements in healthcare and research are such that it deserves official recognition as a medical specialty Cuba.

INTRODUCTION

Pediatric gastroenterologists are physicians who specialize in management of digestive system disorders in children, from birth to the end of adolescence. They approach their medical practice from a pediatric perspective and grounding in clinical gastroenterology, aided by diagnostic technologies for examining the digestive system. Such procedures allow direct examination of the upper digestive tract through esophageal gastroduodenoscopy (for tissue sample collection by mucosal biopsy and esophageal dilation in stenosis), and ileocolonoscopy of the colon and distal small intestine.

Pediatric gastroenterology (PG) specialists perform resections of intestinal polyps; deal with liver, biliary tract and pancreatic diseases; and perform percutaneous and laparoscopic liver biopsies. They also handle comprehensive management of chronic liver diseases, including chronic hepatitis, liver cirrhosis and other genetically caused conditions, and use sclerotherapy or band ligation to treat varices due to portal hypertension or other causes. They perform infant cholestasis and related surgery, including liver transplantation. Pediatric gastroenterologists dedicated to liver and bile duct conditions are recognized as pediatric hepatologists; pediatric hepatology has emerged as a subspecialty of PG in some countries.[¹1.

By the early 1970s, knowledge had developed and the international pediatric community, especially in continental Europe, the UK and North America, recognized the need for different pediatric subspecialties. Applied technology’s contributions to the study of organs and systems, and the experience derived from more accurate diagnosis and improved treatment, were decisive for this recognition.

Today knowledge and experience regarding digestive system growth and development have led to a need for specific medical care. The emergence of PG as a subspecialty is in effect the joining of two medical specialties, pediatrics and gastroenterology, the product of medical scientific and technical progress for better quality and specificity of medical care for this age group.[⁵5. Milla PJ. The European training syllabus in pediatric gastroenterology, hepatology, and nutrition. J Pediatr Gastroenterol Nutr. 2002 Feb;34(2):111–5.] PG has had limited growth in developing countries, but its future there is promising.[¹1. Walker-Smith J, Walker WA.

This paper’s objective is to present the historical evolution of PG in Cuba (including its international context), from its beginnings in the early 1970s at the National Gastroenterology Institute (ING), reviewing the evolution of professional PG practice, its most relevant results in health care and science, and challenges for its extension to pediatric hospitals throughout Cuba.

EVIDENCE ACQUISITION

Institutional sources from ING and the Ministry of Public Health (MINSAP) were reviewed, as well as international and national literature on the history of PG and unpublished texts since PG’s emergence in 1972. Personal records of the author, an eyewitness to most PG milestones in Cuba, were also reviewed.

DEVELOPMENT

Background

Specialized care for childhood digestive disorders emerged in Europe in the 18th century, later in North America. Samuel Gee, a renowned doctor at the Saint Bartholomew Hospital (London), who attended both adults and children, is considered one of the forefathers of European pediatrics and of PG. In 1888, he described chronic diarrhea as the main manifestation of celiac disease in childhood.[¹1. Walker-Smith J, Walker WA. The development of pediatric gastroenterology: a historical overview. Pediatr Res. 2003 Apr;53(4):706–15.]

In the 1960s, after gastroenterology and pediatrics had been established as separate specialties, PG appeared as a specialty internationally because of the need for more highly specialized medical care, facilitated by the advent of the first fiber optic endoscopes for pediatric use. In Latin America, Argentina and Brazil were pioneers in the establishment of the specialty at the end of that decade.[⁶6. Jorge JR. Historia de la Sociedad Latinoamericana de Gastroenterología, Hepatología y Nutrición Pediátrica (S LAG H N P/LAS PG H AN). 35 Años de Historia. (1975-2010) [Internet]. Sao Paulo: Latin American Society of Gastroenterology, Hepatology and Nutrition; c2016 [cited 2016 Mar 21]. Available from https://www.laspghan.org/index.php/institucion/historia-de-la-sociedad. Spanish.
https://www.laspghan.org/index.php/insti... ] PG was certified as a specialty in the USA in 1980 and approved as a medical subspecialty in 1990, under the auspices of the North American Association of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN).[¹1. Walker-Smith J, Walker WA. The development of pediatric gastroenterology: a historical overview. Pediatr Res. 2003 Apr;53(4):706–15.,⁵5. Milla PJ.

J Pediatr Gastroenterol Nutr. 2002;35 Suppl 3:S235–6.]

Distinguished pediatricians such as Harry Shwachman played a decisive role in training the first PG specialists. Expert teachers, such as Arnold Silverman and Allan Walker in the USA, Charlotte Anderson in Australia, Claude Roy in Canada and Jean Francois Rey in France, together with other outstanding Europeans in Finland, Switzerland, Sweden and Germany, played a major role in achieving recognition of PG as a subspecialty. In parallel, pediatric hepatology emerged and developed as part of PG; leading players were Daniel Alagille in France, Alex Mowat in the UK, and Frederick Suchy and William Balistreri in the USA, all known for their clinical and teaching activities and for authoring landmark books that played a key role in development of specialized management of diseases of the gallbladder and liver (including transplantation).[⁹9. Alagille D, Odièvre M. Maladies du foie et des voies biliaires chez l’enfant. Paris: Flammarion; 1978. French. 10. Mowat AP. Liver disorders in childhood. London: Butterworth-Heinemann Ltd; 1998. 496 p.–¹¹11. Suchy FJ, Sokol RJ, Balistreri WF. Liver disease in children. 4th ed. Boston: Cambridge University Press; 2014.] The first comprehensive text on PG was published in 1971: Pediatric Clinical Gastroenterology, by Arnold Silverman, Claude C. Roy and Frank J. Cozzetto. It was also the first textbook used by Cuban pediatric gastroenterologists.[¹²12. Silverman A, Roy CC, Cozzetto FJ. Pediatric Clinical Gastroenterology. 1st. ed. St. Louis: Mosby; 1971.]

PG in Cuba

In 1970, Raimundo Llanio Navarro initiated the Medical Working Group on Pediatric Gastroenterology at ING (of which he was founder and director). In 1972, with the help of pediatrician Eladio Blanco Rabasa, the Pediatric Gastroenterology Service, the first of its kind in Cuba, was established at ING for specialized medical care, applied research and teaching.[¹³13. Castañeda C. Pediatric Gastroenterology in Cuba. J Pediatr Gastroenterology Nutr. 2001 Nov;33(5):525–6.] This constituted the first step in PG development in Cuba as a subspecialty derived from gastroenterology. The first three doctors with pediatric experience (having had a year of pediatric residency) were gradually incorporated in ING from 1970 and trained for two additional years in gastroenterology for pediatric application (ING, unpublished institutional records). They effectively founded PG in Cuba, and consolidated its practice with their scientific activity.

PG’s development was facilitated by Cuba’s interest in diversifying public health. Pediatric wards had already been established in rural hospitals and the National Maternal-Child Health Program was established in 1970,[¹⁴14. Robaina Castellanos RG. A treinta años del inicio del Programa de Atención Materno Infantil en Matanzas: realidades y retos. Rev Méd Electrón [Internet]. 2014 Jan-Feb [cited 2016 Mar 21];36(1). Available from http://www.revmatanzas.sld.cu/revista%20medica/ano%202014/vol1%202014/tema01.htm. Spanish.
http://www.revmatanzas.sld.cu/revista%20... ] which particularly addressed the fight against gastroenteritis, among other diseases of great impact on childhood morbidity and mortality. It also promoted vaccination plans, among various new public health tasks taken on with implementation of the unified, universal and free National Health System (SNS) after 1959.[¹⁵15. Cooper RS, Kennelly JF, Ordunez-Garcia P. Health in Cuba. Int J Epidemiol. 2006;35:817–24.]

At the same time, the three newly trained physicians in ING’s PG service underwent further training: in France, with Alagille, pediatric hepatologist at the Bicêtre University Hospital in Paris (1972–73); in the UK with Charlotte Anderson at the Institute of Child Health in Birmingham (1973), at the Leicester Royal Infirmary (1978) with A.S. McNeish, a specialist in intestinal diseases; and in Mexico with Leopoldo Vega Franco at the Children’s Hospital of Mexico (1974) (ING, unpublished institutional records). The intensive training and knowledge acquired with these professors were decisive contributions to PG’s development in Cuba.

It is worth emphasizing the influence of this initial group of doctors specializing in the study of diseases that were infrequent at the time: their impact on pediatric medical research, postgraduate education of PG specialists for pediatric hospitals in Cuba’s capital and provinces, and the organization of a national network of PG care. The new PG Service quickly became a national reference center for treating childhood digestive disorders.

Specialized care for children and adolescents with a range of digestive diseases was crucial, particularly use of digestive system endoscopy for diagnostic and therapeutic purposes. For conditions of intestinal origin (such as celiac disease), diagnosis required introduction of peroral jejunal biopsy using the pediatric Crosby–Watson capsule, and colonoscopy to study colon pathologies such as ulcerative colitis and Crohn disease (ING, unpublished institutional records). These methods represented new contributions to health care in Cuba.

Progress in treatment of liver diseases, such as chronic hepatitis B, also deserves mention; e.g., with laparoscopic studies and liver biopsy. Cuba was a pioneer in Latin America and the Caribbean in treating chronic hepatitis B with domestically produced interferon. Initially, natural interferon alpha was used and later recombinant interferon alpha, both obtained at the Genetic Engineering and Biotechnology Center in Havana starting in the early 80s. The resulting clinical trials had international impact.[¹⁶16. Castañeda C, Fragoso T, Grá B, Callejas-Lorensen C, Limonta M.

Fragoso T, Castañeda C, Grá B. Valor del fenotipo del Sistema Pi en la deficiencia de alfa 1 antitripsina. Acta Latino-Am Gastroenterol. 1986;16:75–89. Spanish.] were also achievements by ING’s PG specialists, in collaboration with biochemists, biologists and anatomic pathologists.

The most important event for Cuban PG in the past decade was the establishment of the Pediatric Liver Transplant Unit by a multidisciplinary medical team at the William Soler Pediatric University Hospital in Havana, in 2005 (ING, unpublished institutional records).

In Cuba, PG is not yet officially recognized as a specialty. There is only the gastroenterology residency, offered by the Medical University of Havana and the provincial medical universities. ING is recognized as Cuba’s national PG reference center and provides specialized training in endoscopic diagnosis and treatment for pediatric patients, as well as digestive system biopsy, treatment of varices, laparoscopy, percutaneous liver biopsy, interpretation of esophageal and anorectal manometry, and up-to-date management of digestive system diseases. A PG training program lasting 18–24 months, focusing mainly on digestive system endoscopy, has also been offered to pediatricians (ING, unpublished institutional records).

PG services in Cuban pediatric hospitals

First stage

The first specialized PG service in a Cuban hospital was established at the William Soler Pediatric University Hospital in Havana in the late 1970s. Of particular relevance was the performance of endoscopies, liver and jejunal biopsies and other special procedures, carried out by two ING-trained pediatricians (MINSAP, unpublished institutional records).

In the cities of Santa Clara and Santiago de Cuba, in central and eastern Cuba, respectively, PG services had been organized since the end of the 1970s by training pediatricians, who performed valuable clinical and endoscopic work.

Second stage

During the 1980s, at the request of ING pediatric gastroenterologists, a project for PG development was initiated, with three main components: 1) scientific–technical development, 2) prioritized specialty training, and 3) extension of PG services to all pediatric hospitals in Cuba, with acquisition of modern fiberoptic endoscopy equipment, so that only children requiring specialized studies not available in their province need be transferred to Havana. Thus, services with modern equipment purchased in Japan by the Ministry of Public Health (MINSAP) for Cuban pediatric hospitals were established, initially in the cities of Santa Clara, Camagüey and Holguín (ING and MINSAP, unpublished institutional records).

In 1984, a PG service was organized in the Holguín’s Octavio de la Concepción de la Pedraja Pedriatic University Hospital, led by ING-trained Dr. José Soler Franco, chief of service. He established the Digestive Endoscopy Unit and the PG ward, which provides patient care for Holguín and neighboring provinces, as well as PG courses for pediatricians. This service is a reference center for childhood digestive pathology in eastern Cuba (ING and MINSAP, unpublished institutional records).

Also during the 1980s, PG services were established in five pediatric hospitals in Havana, after ING trained pediatricians in gastroenterology (ING and MINSAP, unpublished institutional records). The Pedro Borrás-Marfán Pediatric Teaching Hospital succeeded in establishing a PG service, with a modern ambulatory endoscopy unit, and provided quality health care by gastroenterologists trained as pediatric gastroenterologists. PG services in the other four hospitals had to face shortage of PG specialists and reduced availability of pediatric endoscopy equipment. To date, only Centro Habana Pediatric Teaching Hospital continues to provide PG services (Author’s personal records).

In October 1989 Havana’s Juan Manuel Márquez Pediatric University Hospital opened a PG service with modern Japanese endoscopy equipment and three medical specialists, two of them trained in ING’s Pediatrics Department. Within a few years this unit became a highly specialized service that offered courses and workshops, and successfully developed endoscopic and clinical activity (MINSAP, unpublished institutional records).

The provincial hospitals of Ciego de ávila, Cienfuegos, Sancti Spíritus, Matanzas and Pinar del Rio had already begun to provide PG care. Subsequently, many of these hospitals gradually expanded their cadre of PG specialists, sending other pediatricians for training at ING or at Juan Manuel Márquez Pediatric University Hospital’s Department of Gastroenterology (MINSAP, unpublished institutional records).

Barriers

MINSAP has had great limitations in its capacity to purchase, repair or replace endoscopy equipment (such as pediatric endoscopic capsules), because of obstacles to acquiring parts on the international market due to the long-standing US embargo. It has also had difficulty acquiring other modern equipment, such as expired-hydrogen monitors to measure esophageal pH.[²¹21. Marimón Torres N, Torres Martínez E.

PG milestones in Cuba

Cuban PG’s scientific results are expressed in the organization and implementation of national scientific events; participation in international congresses; re-search awards and recognitions (which indicate the work’s scientific rigor and have had substantial impact in the Latin American region); and in a considerable volume of monographs and scientific articles. Table 1 contains a detailed list of scientific and other events pertinent to the history of Cuban PG.

Among those events, the 9th Meeting of the Latin American Society of Gastroenterology, Hepatology and Nutrition (LASPGHAN), (Havana, 1989), stands out, both for its political and scientific significance. The representatives of Uruguay, the country selected to host the event, ceded their hosting rights to Cuba, in solidarity with Cuba because of its isolation in the Latin American context at the time, and to recognize Cuban PG accomplishments in health care and research. More than 250 physicians from Latin America attended, including members of LASPGHAN, as well as leading international PG experts.

So far this century, Cuban PG practitioners have been lead authors, writers or editors of important teaching and reference materials: books, articles, and chapters in more than a dozen books. [²²22.

Challenges

PG in Cuba, remains to be formally recognized as a medical subspecialty, following academic principles and programs established internationally for PG residency training.[¹1. Walker-Smith J, Walker WA. The development of pediatric gastroenterology: a historical overview. Pediatr Res. 2003 Apr;53(4):706–15.,³3. Rezzónico CA. La Pediatría y sus especialidades: interrelación del pediatra y del especialista. Salud Infantil. 1993;3:76–80. Spanish.–⁵5. Milla PJ.

J Pediatr Gastroenterology Nutr. 2001 Nov;33(5):525–6.] To date, pediatric gastroenterologists who complete pediatric training in addition to a gastroenterology residency have no recognition for their PG specialization. We urgently need to train new PG professionals to ensure the future of the specialty, which in the past decade has been affected by the retirement of the first generation of PG-dedicated physicians.

Other important tasks are consolidation of achievements in digestive system endoscopy (techniques requiring specific train-ing),[¹1. Walker-Smith J, Walker WA.

The achievements of Cuban PG, both in its scientific production and its clinical practice have been attained despite the handicap of its historical origin in gastroenterology rather than pediatrics, which limits its growth. Cuba’s sustained low rates of infant mortality also speak to PG’s contributions.[⁵²52. Gorry C. Lowering Infant Mortality in Cuba. MEDICC Rev. 2015 Jan;17(1):11–3.]

CONCLUSIONS

In 1972, Cuba was the first country in Central America and the Caribbean to develop the professional practice of PG as a de facto pediatric subspecialty. Its scientific and clinical contributions in providing quality management of digestive diseases in children, have had great impact, reflected in SNS’s establishment of a national network of PG services in pediatric hospitals throughout Cuba. PG’s development and achievements in healthcare and research are such that it deserves official recognition as a medical specialty Cuba.
