Salt poisoning is a rare cause of severe hypernatremia in children resulting from the ingestion of toxic amounts of sodium chloride, either from accidental or intentional administration of salted solutions.We present the case of a newborn admitted to a pediatric emergency department for lethargy and reduced oral intake; his laboratory evaluation showed severe hypernatremia ([Na + ] of 174 mmol/L). The infant developed convulsive status epilepticus during treatment. Neuroimaging showed a tetraventricular hemorrhage, a large right-sided parenchymal hemorrhage with midline shift, and several left hemorrhagic foci. Etiologic evaluation for hypernatremia did not reveal a renal or extrarenal source of water loss nor an intercurrent illness to explain the reduced oral intake. A careful review of how the parents prepared the infant formula revealed an error in dosing the ratio of powder/water, resulting in hyperosmolar infant formula. The infant was diagnosed with salt poisoning as the major cause of hypernatremia. After careful correction of hypernatremia and the use of antiseizure medication, the patient improved and was discharged. The parents were given a careful review of instructions for infant formula preparation.Due to its rarity, a high index of suspicion is mandatory for a correct diagnosis of salt poisoning. Timely and adequate treatment is needed due to the high risk of intracerebral bleeding, seizures, and irreversible neurologic injury. Children, particularly newborns and infants, depend upon adults to ingest water and, thus, have more difficulty in maintaining electrolyte balance. Therefore, it is of utmost importance that parents are educated about childcare, particularly on the importance of careful infant formula preparation.

We report the case of a 28-year-old male, with a past history of recurrent pharyngitis and tonsillectomy, who presented to the emergency department with fever, pharyngitis, and cervical adenitis. Inflammatory markers were elevated and the patient was initially started on ceftriaxone with remission after four days. However, the symptoms recurred three weeks later and an autoinflammatory disease was suspected. After exclusion of other illnesses, a diagnosis of periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA) syndrome was confirmed. The patient was successfully treated with a single dose of 60 mg of prednisolone at the beginning of the flare.PFAPA syndrome has been classically diagnosed solely in children but cases in adults are being increasingly recognized. Despite the increasing evidence of the delayed onset of PFAPA syndrome during adulthood, no specific tools are available to detect it and diagnosis is currently based on clinical diagnostic criteria, which have very low specificity and are tailored to pediatric patients. This case report stresses the need to consider this entity seriously despite its rarity, even among the adult population, so as to reduce iatrogenesis, start appropriate therapy in a prompt manner, and improve the quality of life of PFAPA patients.

BackgroundAlthough declining, adolescent pregnancy remains an important health concern and is associated with adverse maternal and fetal outcomes. We aimed to characterize adolescent pregnancy in a level II hospital and the observed maternal, fetal, and perinatal complications. MethodsWe conducted a case-series study of five-years duration with adolescent mothers and their newborns. We collected sociodemographic, obstetric, and neonatal data through chart review and conducted a comparison analysis between newborns who needed hospitalization and those who did not. ResultsWe identified 112 newborns with adolescent mothers. Most pregnancies were unplanned (89.3%) and the start of pregnancy surveillance was late. The most frequent complications were intrauterine growth restriction, oligohydramnios, and threatened preterm labor. Prematurity was found in 9.8% of the newborns and 0.9% had less than 32 weeks at the time of birth. Thirteen newborns (11.6%) needed hospitalization in the neonatal intensive care unit, with three (23%) needing invasive ventilation. The main diagnoses of admission were prematurity, social risk, low birth weight, feeding difficulties, and newborn respiratory distress syndrome. Hospitalization seemed associated with less frequent breastfeeding. Among the hospitalized newborns, there was a high rate of discharge at the care of a relative or an institution (30.8%). Surprisingly, surveillance during pregnancy did not seem to differ between newborns that needed hospitalization and those that did not. DiscussionAdolescent pregnancy is associated with poor surveillance as well as obstetric and neonatal complications. Newborns of adolescent mothers have a high hospitalization rate, but further investigations are needed to fully understand the contributing factors. The creation of multidisciplinary teams is fundamental for reducing complications, and appropriate reproductive health programs should focus on reducing adolescent pregnancy through better access to education and contraception.

Background Colorectal cancer is one of the most common cancers worldwide. Psychological morbidity has an important impact on quality of life and major clinical outcomes. Several data have shown that the immune system may be a key player on the relation between psychological features and cancer outcomes. Natural Killer (NK) cells have been shown to be influenced by psychological factors. The aim of this investigation was to assess the impact of anxiety, depression, and anger state, trait, and expression on the immune response, particularly, their effect on NK cells and CD8+ T cells in surgical colorectal cancer patients. Methods We studied 54 surgical colorectal cancer patients and assessed patients pre-surgically, post-surgically, and 12 months after surgery (follow-up). We applied the Hospital Anxiety and Depression Scale and the State-Trait Anger Expression Inventory and measured peripheral T cells, CD8+ T cells, and NK cells. We did a cross-sectional analysis as well as a longitudinal assessment of the variables during the follow-up period. Results Pre-surgical assessment: Trait anger, angry reaction, and anger-out had a significant negative correlation with NK cells. The lymphocytes values were unaffected by the presence of clinical anxiety or depression. Post-surgical assessment: Patients without clinical anxiety had higher levels of T cells. Angry reaction was negatively correlated with NK cells. Lymphocytes values were unaffected by the presence of clinical depression. Follow-up assessment: Patients without clinical depression had higher T cell counts. Trait anger and angry reaction were negatively correlated with the levels of NK cells. The lymphocytes values were unaffected by the presence of clinical anxiety. Longitudinal assessment: Angry-temperament, anger expression, and anger-in reduced significantly from the first to the second assessment. Anxiety, state anger, and trait anger significantly diminished from the pre-surgical to the follow-up assessment. Depression levels did not alter during the follow-up period. The lymphocyte count, and particularly T cells and CD8+ T cells, was significantly higher in the follow-up when compared with the pre-surgical assessment. Conclusion Our study suggests the existence of a relation between psychological response and immune response in colorectal cancer patients. We identified the importance of emotional regulation as a potential modulator for NK cell counts. Higher values of propensity to experience anger states and express them outwards seem to be associated with lower NK cell counts.

Acute cholecystitis is an exceedingly rare condition in young children; nevertheless, it should be considered while investigating an acute abdomen. We report a case of a five-month-old male who presented to the pediatric emergency department with inconsolable crying, decreased oral intake, vomiting, diarrhea, and a tender right upper quadrant of the abdomen. Laboratory studies revealed elevated gamma-glutamyl transferase and alkaline phosphatase and the abdominal ultrasound was suggestive of acute calculous cholecystitis. The patient was treated with intravenous hydration and antimicrobial therapy, avoiding the need for emergent cholecystectomy. A calcium bilirubinate calculus was observed in the feces but no etiology was found after extensive investigation. We aim to raise awareness of this diagnosis and the need for prompt initiation of therapy to avoid complications.
