Fetal macrosomia is strongly associated with adverse obstetrical outcome. Case presentation We report a rare case of excessive neonatal weight in a medically unsupervised pregnancy and give a literature review on this significant subject. A 38 year-old woman (Gravida 8 Para 7) presented herself at 42 2/7 weeks of gestation at the labor ward. The pregnancy had not been supervised medically. Labor induction was initiated. Due to failure to progress and suspicion of a disproportion of the fetal head and maternal pelvis an urgent caesarean section was performed. A morbidly macrosomic male infant was delivered (birth weight: 6,760 g [>99. percentile], length: 60 cm [>99. percentile]). Conclusions The morbidity for infants and women increases with a birth weight exceeding 4,500 g. Gestational diabetes mellitus, a high pre-pregnancy body mass index and excessive gestational weight gain have been independently associated as risk factors. The increase in pregnancies complicated by maternal obesity and gestational diabetes emphasizes the necessity of evidence-based clinical interventions to prevent or reduce these diseases. If prenatal care is not frequented by mothers-to-be there are no options open for obstetricians to detect fetal macrosomia and to intervene.","PeriodicalId":9617,"journal":{"name":"Case Reports in Perinatal Medicine","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90985341","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}

Case presentation A female infant born at 34 weeks gestation required intubation and ventilation at birth. Chest radiographical imaging revealed bilateral density to the bases of both lung fields with raised hemi-diaphragms. Ultrasound imaging showed focal diaphragmatic eventration with bulging of the dome of the liver into the right and left hemithoraces. Assessment of the electrical activity of the diaphragm during a spontaneous breathing trial demonstrated a mean amplitude consistent with that of ventilated infants of the same gestational age with intact diaphragms. Hence she was extubated which was successful. Chest radiographic thoracic area measured post extubation was 1,654 mm2, equivalent to that of a term infant with severe congenital diaphragmatic hernia. As the electrical activity of the diaphragm was normal this suggests replacement of the diaphragmatic muscle tissue with fibrous bands was likely to be only partial, and hence why extubation was successful. She had other abnormalities presenting in the neonatal period including dermal melancytosis, central hypotonia, hyperinsulinism and poor feeding. The infant underwent extensive investigation which revealed a KMT2D gene mutation associated with Kabuki syndrome. Conclusions Physiological pulmonary measurements may add clinical management in bilateratal diaphragmatic eventration.","PeriodicalId":9617,"journal":{"name":"Case Reports in Perinatal Medicine","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86815298","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}

Very few cases of these syndromes have been described during pregnancy. Here we report a case of autoimmune polyglandular syndrome type-2 presenting during pregnancy and complicated by preeclampsia with severe features. Case presentation The patient is a 35-year-old G7P0242 woman with a history of adrenal insufficiency, type 1 diabetes mellitus, and chronic lymphocytic thyroiditis. She was admitted to our institution at 34 weeks’ gestation for preterm contractions, nausea, and lower extremity edema for a few weeks prior to admission. At 35 weeks’ gestation, she developed preeclampsia with severe features requiring repeat cesarean section with good maternal and fetal outcomes. Recognizing the occurrence of this rare syndrome during pregnancy, adequate replacement of the deficient hormones, and close maternal and fetal surveillance are essential to achieving favorable outcomes. Conclusions To our knowledge, this is the first reported case of a pregnant woman with autoimmune polyglandular syndrome type-2 complicated by preeclampsia with severe features.","PeriodicalId":9617,"journal":{"name":"Case Reports in Perinatal Medicine","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86434497","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 well known that hamartoma can be associated with congenital midline cervical cleft and therefore cause a variety of symptoms. In general, they are benign and indolent, but they can be the cause of complex morbidity if they are localized within specific regions, such as the head and neck, which represent highly sensitive and vulnerable areas. Case presentation The reported case is unusual because of the presence of a congenital mesenchymal hamartoma along with the median cervical cleft, in a 1-day-old neonate, without the presence of any respiratory symptoms or associated congenital features. Although extremely rare, hamartomas should be included in the differential diagnosis of congenital neck masses, with emphasis on diagnostic approach, to avoid overly aggressive treatment and possible complications, such as infection, further mass growth, malignant transformation and compression of the adjacent neck structures. Conclusions Appropriate and timely treatment of the hamartoma of the neck in neonates, with further follow-up is necessary to avoid an overly aggressive treatment and to distinguish benign from malignant lesions, which is necessary for successful curative outcome.","PeriodicalId":9617,"journal":{"name":"Case Reports in Perinatal Medicine","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76807650","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}

Intra-arrest POCUS demonstrated right ventricular dilation and hypokinesis adding to a presumed hemorrhagic arrest etiology. Venoarterial extracorporeal membrane oxygenation (VA-ECMO) was initiated at the bedside following the POCUS findings. ROTEM further clarified the etiology of hemorrhage as disseminated intravascular coagulation (DIC), and in combination with the POCUS findings led to a final diagnosis of amniotic fluid embolism with DIC. The patient was maintained on VA-ECMO without heparin in the setting of DIC. She had a complicated hospital course but was discharged home with her healthy child and no residual physical or neurologic deficits.

Patients with HD may experience reactions that mimic other conditions making diagnosis challenging. Case presentation We present a case of a patient from Chuuk, a state of the Federated States of Micronesia with a sepsis-like illness and worsening painful rash immediately postpartum. Antepartum, the patient noted a pruritic rash on her legs. Four hours after delivery, the patient became febrile and later developed systemic inflammatory response syndrome (SIRS). The rash rapidly spread to other areas of her body and became painful and edematous. Eight weeks after delivery, a skin biopsy revealed tuberculoid granulomatous dermatitis consistent with HD. Conclusions HD and its associated reactions are easily misdiagnosed.
