Atresia pilórica / Pyloric Atresia

Introducción: La atresia pilórica es una afección rara, que en el 40-50 por ciento de los casos se asocia a otras anomalías, frecuentemente con la epidermolisis bullosa, asociación conocida como síndrome de Carmi. Objetivo: Informar sobre la evolución de una paciente tratada por atresia pilórica que tenía además una epidermolisis bullosa. Presentación del caso: Recién nacida con antecedentes prenatales de polihidramnios, parto eutócico a las 30,4 semanas, sepsis ovular materna, peso al nacer 1430 gramos; múltiples lesiones en piel, ampollosas y aplasia cutis en pierna izquierda. Se ventiló desde sala de partos, La paciente no toleró la alimentación enteral mínima. Se realizó estudio radiográfico y no se visualizó paso de contraste al píloro. Se diagnosticó una atresia pilórica y se operó al cuarto día de nacida. La paciente tenía una atresia pilórica tipo 2: sustitución del tejido pilórico por tejido fibroso. Se hizo una gastroduodenostomía. En su evolución se incrementaron por día las lesiones en piel, y tuvo reapertura del ductus arterioso, trastornos hidroelectrolíticos, y hemidinámicos que provocaron el fallecimiento a los 14 días de nacida. Conclusiones: La atresia pilórica es una afección muy rara, que debe tenerse en cuenta en recién nacidos con epidermolisis bullosa por la frecuente asociación entre estas dos afecciones; además, cuando existen antecedentes de polihidramnios y no tolerancia a la alimentación enteral. Los pacientes con la asociación atresia pilórica y epidermolisis bullosa generalmente presentan una evolución desfavorable(AU)

Introduction: Pyloric atresia is a rare condition, which in 40-50 percent of cases is associated with other anomalies, often with epidermolysis bullosa, an association known as Carmi syndrome. Objective: To report on the evolution of a patient treated due to pyloric atresia who also had epidermolysis bullosa. Case presentation: Female newborn with prenatal history of polyhydramnios, eutocic delivery at 30.4 weeks, maternal ovular sepsis, birth weight 1430 grams, with multiple skin lesions, blisters and aplasia cutis in the left leg. She was ventilated from the delivery room. The patient did not tolerate minimal enteral feeding. A radiographic study was performed and no contrast passage to the pylorus was visualized. Pyloric atresia was diagnosed and operated on the fourth day of birth. The patient had pyloric atresia type 2: replacement of pyloric tissue by fibrous tissue. A gastroduodenostomy was done. In its evolution, skin lesions increased per day and reopening of the ductus arteriosus was performed, she had hydroelectrolyte disorders, and hemidynamic disorders that caused death at 14 days of birth. Conclusions: Pyloric atresia is a very rare condition, which should be taken into account in newborns with epidermolysis bullosa due to the frequent association between these two conditions, also when there is a history of polyhydramnios and no tolerance to enteral feeding. Patients with pyloric atresia and epidermolysis bullosa usually have an unfavorable outcome(AU)

Gastric remnant cancer patients had a better prognosis than upper-third gastric cancer patients in a case-control study after surgical treatment.

BACKGROUND: The aim was to compare the clinicopathological features and prognostic outcomes of gastric remnant carcinoma patients with those of patients with upper-third gastric cancer. METHODS: Clinical data extracted from 112 gastric remnant carcinomas and 367 upper-third gastric cancer patients were analyzed to explore the clinicopathologic differences between two groups. After radical resection, prognostic difference between them was evaluated through a 1:2 matched case-control study. RESULTS: The pattern of gastric remnant carcinomas showed a male predominance. Undifferentiated type histology, depth at T4 stage and distant metastases were more frequent in gastric remnant carcinomas than in upper-third gastric cancers (P <0.05). The radical resectability of gastric remnant carcinomas was lower and the multi-visceral resectabilitiy was relatively higher than the other group (P = 0.00). Gastric remnant carcinomas trended to have a higher incidence of metastases to either mesojejunum or lower mediastinal lymph nodes than upper-third gastric cancers, but patient survival was not significantly different. In the case-control study, gastric remnant carcinomas had a better prognosis than upper-third gastric cancers after radical resection when the clinicopathologic features and surgical treatment were matched. CONCLUSIONS: Although there was no significant prognostic distinction between gastric remnant carcinomas and upper-third gastric cancer, after radical surgical treatment, patients with the former had an even better prognosis.

Safe temperature range for intraoperative and early postoperative continuous hyperthermic intraperitoneal perfusion in a swine model of experimental distal gastrectomy with Billroth II reconstruction.

BACKGROUND: The current study sought to investigate the safety of intraoperative and early postoperative continuous hyperthermic intraperitoneal perfusion (IEPCHIP) at different temperatures in a swine model of experimental distal gastrectomy with Billroth II reconstruction. METHODS: Thirty pigs were randomly divided into 5 groups. Two groups were used as the control groups (groups A1 and A2), and 3 groups were used as the perfusion groups (groups B, C and D). Pigs in group A1 received distal gastrectomy with Billroth II reconstruction only. Pigs in groups A2, B, C and D received the same surgery as group A1, followed by IEPCHIP at 37 ± 0.5°C, 42.5 ± 0.5°C, 43.5 ± 0.5°C or 44.5 ± 0.5°C, respectively. The perfusion time was assessed for each pig in group A2 as well as in the perfusion groups, and the perfusions were performed twice for each group. The first perfusion was conducted intraoperatively, and the second perfusion was initiated 1 day after surgery. Data concerning vital signs and hepatic and renal function were collected. Parameters concerning anastomotic healing, the pathology of the anastomotic tissue and abdominal adhesion were compared. RESULTS: The vital signs and hepatic and renal functions of the pigs in groups A1, A2, B and C were not significantly affected by this procedure. In contrast, the vital signs and hepatic and renal functions of the pigs in group D were significantly affected. Compared to the pigs in groups A1, A2 or B, the anastomotic bursting pressure, breaking strength and hydroxyproline content in group C and D pigs were significantly lower. No significant differences were observed in these parameters between groups A1, A2 and B. Abdominal adhesion was more severe in group D pigs. Collagen deposition in group A1, A2 and B pigs was dense in the anastomosis, and inflammatory cell infiltration was observed in group D. CONCLUSIONS: IEPCHIP at 42.5 ± 0.5°C was safe and caused minimal impairments. However, anastomotic healing was affected by perfusion at 43.5 ± 0.5°C and 44.5 ± 0.5°C, and abdominal adhesion was most severe in the group D animals, which were perfused at 44.5 ± 0.5°C.

Acquired copper deficiency following prolonged jejunostomy feeds.

A 19-year-old man who developed extensive oesophageal lye (Alkali) stricture and received long-term enteral nutrition (eight months) with a jejunostomy tube developed macrocytic anaemia (Hb: 41 g/L) with leucopenia (white blood cell [WBC]: 3.0 x 10(9)/L). The patient's serum vitamin B12, folate, iron and liver function tests were normal. Bone marrow examination revealed gross erythroid hyperplasia and cytoplasmic vacuolization of erythroid and myeloid elements. Further investigations revealed low serum copper (0.3 micromol/L) and ceruloplasmin concentrations (<30 mg/L) with marginally low normal serum concentration of red cell peroxidase (13 U/gHb), establishing the diagnosis of copper deficiency anaemia. The anaemia and leucopenia responded intermittently to intravenous copper therapy, but the serum copper concentration dropped when intravenous copper therapy was withdrawn. Enteral jejunostomy copper supplementation failed to maintain adequate serum copper concentrations. After stabilizing the general condition of the patient, a pharyngo-gastric anastamosis was performed and normal oral diet commenced, which restored normal serum copper concentration. This case report suggests that copper supplements in the form of copper sulphate are not adequately absorbed when administered through a jejunostomy tube.

Nutrición y SIDA / Nutrition and AIDS

La infección por el VIH en la infancia es un importante problema sanitario. Se calcula que cada año nacen 400-600 hijos de madres seropositivas.El diagnóstico precoz de la infección por el VIH en el niño, es de gran importancia para instaurar lo antes posible tratamiento antirretroviral, profilaxis de infecciones oportunistas, inmunización activa y pasiva, así como un soporte psicosocial y nutricional adecuado.Estos niños presentan una disregulación en el metabolismo de las citocinas que parecen jugar un importante papel en la malnutrición, la cual es de etiología multifactorial y puede presentarse en cualquier momento evolutivo de la enfermedad.Sería importante determinar los índices nutricionales con mayor poder discriminativo para valorar la malnutrición; pues se ha encontrado una correlación entre el deterioro de la situación clínica, inmunológica y nutricional.Las nuevas estrategias terapéuticas de la desnutrición en niños con infección por VIH, se basan en la administración de acetato de megestrol y hormona de crecimiento cuyo efecto parece ser beneficioso (AU)

[Organ-sparing operations in pyloroduodenal stenosis caused by peptic ulcer]. / Organosokhraniaiushchie operatsii pri piloroduodenal'nom iazvennom stenoze.

An experience with the treatment of 106 patients with pyloroduodenal stenosis of ulcerous etiology by vagotomy with draining operations has shown high efficiency of these measures resulting in lower rate of postoperative lethality. Selective proximal and stem vagotomy does not aggravate gastric atony in patients with stenosis. Electro-stimulation was found to be an effective method of treatment of this complication in the postoperative period of patients with gastric atony.
