The Peutz-Jeghers Syndrome (PJS) is an autosomal dominant neoplastic syndrome defined by hamartomatous polyps through the gastrointestinal tract, development of characteristic mucocutaneous pigmentations, and an elevated lifetime cancer risk. The majority of cases are due to a mutation in the STK11 gene located at 19p13.3. The estimated incidence of PJS ranges from 1:50,000 to 1:200,000. PJS carries an elevated risk of malignancies including gastrointestinal, breast, lung, and genitourinary (GU) neoplasms. Patients with PJS are at a 15- to 18-fold increased malignancy risk relative to the general population. Radiologists have an integral role in the diagnosis of these patients. Various imaging modalities are used to screen for malignancies and complications associated with PJS. Awareness of various PJS imaging patterns, associated malignancies, and their complications is crucial for accurate imaging interpretation and patient management. In this manuscript, we provide a comprehensive overview of PJS, associated malignancies, and surveillance protocols.

Peutz Jeghers Syndrome

Peutz-Jeghers syndrome (PJS) is an extremely rare autosomal dominant hereditary disease characterized by the growth of hamartomatous polyps in the gastrointestinal tract, mucocutaneous pigmented macules and an increased risk of malignant neoplasms of various localizations. In most cases the development of PJS is associated with the presence of a mutation in the STK11 gene, but not all patients have this mutation. This review presents the historical aspects of the first data on PJS, considers the clinical manifestations of the disease, current diagnostic methods, as well as recent knowledge about the genetic causes, about the risk of malignant neoplasms in patients with PJS, existing guidelines for screening and treatment of patients with PJS. However, the presence of a number of unresolved issues in genetics, monitoring and treatment indicates the need for further research.

Peutz Jeghers Syndrome

AbstractHamartomatous polyps of the gastrointestinal tract can occur sporadically, however, for several hereditary syndromes, their presence is one of the major clinical features. Peutz–Jeghers syndrome, juvenile polyposis syndrome, and the PTEN hamartoma syndromes are autosomal dominant inherited disorders that predispose to formation of such polyps, especially in the colon and rectum. These can lead to increased colorectal cancer risk and should be followed and managed appropriately. In this article, the three major hereditary hamartomatous syndromes are described, including presentation, colorectal surveillance, and management.

Peutz–Jeghers Syndrome is an autosomal dominant inheritedhamartomatous polyp. We present a case of a 5-year-old young boywith a history of per rectal bleeding and mass protruding out of the anus. Physical examination revealed presence of mucocutaneous pigmented lesions over the tongue, and few hamartomatous polyps protruding out of the rectum suggesting Peutz–Jeghers syndrome. The presence in early infancy of small, well-demarcated and dark-brown to blue-black lentigines on the lips,buccal mucosa and perioral skin, should alert the clinician to Peutz–Jeghers Syndrome.DOI: http://dx.doi.org/10.3126/jpn.v4i8.11597 Journal of Pathology of Nepal; Vol.4,No. 8 (2014) 677-679

Peutz Jeghers Syndrome

Background: Peutz-Jeghers syndrome (PJS) is an inherited autosomal dominant disease determined by a mutation localized at 19p13.3 characterized by the occurrence of gastrointestinal hamartomatous polyps in association with mucocutaneous hyperpigmentation. The manifestation of PJS may first be encountered by a dentist during routine examination due to the presence of pigmented spots in the oral cavity. Purpose: To prevent a high risk of PJS, the dentist must establish its oral manifestation through early detection. Case: A 14-year-old male patient attended complaining of a week-long pain at the corners of the lips. An extra-oral exam revealed fissure lesions, redness, white crust and pain. The patient had experienced bleeding in his bowel movements, abdominal pain, nausea and vomiting since childhood. A number of black, painless, macular lesions, some 1-3 mm in diameter, were present on the upper lips, lower lips, fingers and palms. Case management: The patient was referred for a complete blood count check. The results obtained confirmed him to be suffering from severe anemia and he was, therefore, referred to an internist for treatment for PJS. Conclusion: It can be concluded that the early detection of PJS is crucial in order that the patient receives prompt treatment.

Peutz Jeghers Syndrome

Abstract: Hamartomatous polyposis syndromes or Peutz-Jeghers syndrome (PJS) is a hereditary autosomal dominant disease characterized by benign hamartomatous polyps and mucocutaneous pigmentation in the digestive tract. It occurs mostly in the small intestine during first decade of life but frequently in the colon and stomach. Only a few cases have been reported in the duodenum1. Polyposis syndromes are common cause of adult intussusceptions, with polyps acting as lead points. Adult intussusceptions are rare and is almost always associated with that lead point2. Although hamartomatous polyps are not pre-malignant, there is an increased risk of gastrointestinal and non-gastrointestinal malignancy, commonly involving the small bowel. Most patients of PJS presents with acute abdomen and diagnosed as intussusceptions, commonly entero-enteric type but colo-colic intussusceptions are rare in Peutz-Jeghers syndrome3. To the best of our knowledge, synchronous colo-colic intussusception association in Peutz-Jeghers syndrome has not been previously reported.

Metabolic Alteration

Schizophrenia is a chronic and severe mental disorder with antipsychotics as primary medications, but the antipsychotic-induced metabolic side effects may contribute to the elevated risk of overall morbidity and mortality in patients with psych-iatric diseases. With the development in sequencing technology and bioinformatics, dysbiosis has been shown to contribute to body weight gain and metabolic dysfunction. However, the role of gut microbiota in the antipsychotic-induced metabolic alteration remains unknown. In this paper, we reviewed the recent studies of the gut microbiota with psychiatric disorders and antipsychotic-induced metabolic dysfunction. Patients with neuropsychiatric disorders may have a different composi-tion of gut microbiota compared with healthy controls. In addition, it seems that the use of antipsychotics is concurrently associated with both altered composition of gut microbiota and metabolic disturbance. Further study is needed to address the role of gut microbiota in the development of neuropsychiatric disorders and antipsychotic-induced metabolic disturbance, to develop novel therapeutics for both neuropsychiatric disorders and metabolic dysfunction.
