The objective of this study is to comprehensively describe the nosological and pathogenic implications of this neurodegenerative disorder, given the unclear diagnosis of MMN and the significant challenges it poses.Clinical cases: We present three clinical cases with a chronic clinical presentation, in which neuroconduction studies were performed, revealing the presence of anti-IgM GM1 antibodies, consistent with the diagnosis of motor multifocal neuropathy. Although the treatment administered in these cases was successful, it is important to note that the diagnosis of MMN experienced some delay, emphasizing the need for greater awareness and understanding of this disease.Conclusion: The diagnosis of motor multifocal neuropathy is often delayed, and an incorrect treatment can worsen symptoms, especially due to its similarity to other neuropathies and nerve and muscle diseases. Despite a generally favorable prognosis, the lack of early diagnosis can lead to severe motor sequelae. In this study, we provide detailed descriptions of three clinical cases from a reference center in Mexico, presenting their clinical manifestations, observed neurophysiological patterns, and treatment response.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142607701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Palliative care is another form of care and organization of health problems that improve quality.Objective: To determine the incidence of patients with advanced chronic illness and need of palliative care (NPC) and intrahospital mortality in a reference hospital.Methods: Prospective observational study in hospitalized patients over 18 years of age in the internal medicine department who met at least one criterion of the NECPAL CCOMS-ICO tool. They were followed until death or discharge to determine intrahospital mortality. We used descriptive and inferential statistics.Results: We studied 370 admissions from April to August 2021, including 110 patients, 59 women (55.3%) and 51 men (44.7%), age 65.5 ± 15.85 years. The incidence of NPC was 29.7%. The most frequent comorbidity was oncologic in 39 patients (35.5%), followed by chronic heart disease in 17 patients (15.5%); 38 patients were classified as NECPAL grade I (34.5%), 44 NECPAL II (40%) and 28 NECPAL III (25.5%). Twenty-five patients died during their in-hospital stay, with a mortality of 22.7%.Conclusions: The incidence of hospitalized patients in need of palliative care is considerable, more than half of them for non-oncologic pathology. More effective care strategies are required for external referral and multidisciplinary in-hospital care.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142607788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dual kidney transplantation (DRT) should be offered to elderly patients with lower immunological risk and with a lower body mass index. DCE are considered donors who died due to stroke, ≥ 60 years old or aged between 50 and 59 years, with diabetes or previous hypertension, clinical proteinuria, estimated glomerular filtration rate (eGFR) between 30 and 60 mL/min, or Terminal serum creatinine > 2.5 mg/dL.Clinical case: 57-year-old male patient undergoing TRD of a 67-year-old DCE, with creatinine of 2 mg/dL at the time of extraction, without previous pathologies, with eGFR: 34 mL/min, KDPI: 92% , KDRI: 1.64, Remuzzi pre-implantation biopsy 5, with 14-hour cold ischemia. He was discharged on the eighth day with a creatinine of 1 mg/dL. At 45 months with creatinine of 0.9 mg/dL, and eGFR by CKD-EPI of 91 mL/min/ 1.73m2.Conclusion: TRD is an alternative for ECD grafts. The \"old for old\" strategy allows TRD in older recipients a better survival than being on replacement treatment. The correlation with the KDRI, KDPI scales and the preimplantation biopsy according to the Remuzzi score improves transplant results by discarding kidneys with severe histopathological alterations, this can help reduce the rate of discarding SCAD and kidneys.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142607579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a partial or complete autosomal structural anomaly of the short arm of chromosome 9. It is generally caused by a reciprocal parental translocation between chromosome 9 and another autosome; spontaneous genetic alteration (de novo) is rare. It presents great phenotypic variability due to the variable size of the chromosome fragment involved.Clinical case: We present the case of a patient diagnosed with trisomy of the short arm of chromosome 9 with a karyotype with a chromosomal complement 46,XX,add(9)(p24), interpreted as an additional chromosome fragment on chromosome 9p. A microarray study was carried out, which reported that the 9p24.3-p13.1 region is found in triple dose, which corresponds to a partial trisomy 9p or Rethoré syndrome, which is a low prevalence entity, with an expressiveness and variable prognosis. In the present case, the finding of a murmur and diagnosis of pulmonary valve stenosis was the initial approach; The heart disease described in our patient has not been reported in the literature as part of the clinical picture, meaning that it was not an initial diagnostic suspicion.Conclusion: Despite having described an already defined phenotype, other clinical data that are not documented should be considered, and when new clinical evidence is found, report it and thereby expand the phenotype for a timely diagnosis.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142607767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incidence is very low, so our objective is to present the case of a patient with ectopic pancreas as a rare cause of obscure gastrointestinal bleeding.Clinical case: A 70-year-old man presented with melena, anemia, and weight loss. The initial approach involved endoscopic studies (panendoscopy, colonoscopy, enteroscopy), a tagged red blood cell scan and computed tomography, none of which identified the bleeding site. Therefore, an exploratory laparoscopy was performed, revealing a 3 x 3 cm exophytic lesion in the proximal jejunum, which was completely resected. Histopathology confirmed an ectopic pancreas.Conclusions: This condition is an uncommon but potentially serious cause of gastrointestinal bleeding, as the definitive diagnosis is often delayed. Therefore, clinical suspicion is crucial for early diagnosis and timely treatment, involving a multidisciplinary team of specialists in gastroenterology, radiology, pathology, and general surgery. In this manuscript, we present one of the few reported cases of ectopic pancreas as the cause of mid-intestinal bleeding.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142607705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All procedures were performed by a single surgeon using antecolic and retrogastric configuration. Study variables: weight, BMI, mesenteric gap closure, suture material used, post-surgical complications.Results: 00 patients were included, 64 women and 36 men, age 40.33 ± 2.08 years. The prevalence of Petersen's space hernia was 3% with a mean presentation time of 18 ± 7.54 months. The variables related to its development in the 3 cases were closure of the mesenteric gap, height, body mass index (BMI) and weight after the surgical procedure. All patients underwent reoperation, reducing the content and closing the mesenteric gap with non-absorbable suture material.Conclusion: The development of the hernia not only depends on the closure of the mesenteric gap, but also on the reduction of weight and loss of volume of the mesentery with the reopening of the space.","PeriodicalId":94200,"journal":{"name":"Revista medica del Instituto Mexicano del Seguro Social","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142607709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
