The Johanson-Blizzard Syndrome (JBS) is an autosomal recessive disorder with a characteristic phenotype, including dwarfism, a beaked nose with aplastic alae nasi, a high forehead, mid-line ectodermal scalp defects with sparse hair and absent eyelashes/eyebrows, prominent scalp veins, low set ears, a large anterior fontanelle, micrognathia, thin lips, absent permanent dentition and microcephaly. In addition to the characteristic facial features, associated conditions include congenital heart disease, exocrine/endocrine pancreatic dysfunction, hypothyroidism, hypopituitarism, mental retardation, sensorineural hearing loss and vesico-ureteral reflux. A case is presented and the potential anaesthetic implications of this syndrome are discussed.

Solitary median maxillary central incisor syndrome (SMMCI) is a complex disorder consisting of multiple, mainly midline defects of development resulting from unknown factor(s) operating in utero about the 35th-38th day(s) from conception. It is estimated to occur in 1:50,000 live births. Aetiology is uncertain. Missense mutation in the SHH gene (I111F) at 7q36 may be associated with SMMCI. The SMMCI tooth differs from the normal central incisor, in that the crown form is symmetric; it develops and erupts precisely in the midline of the maxillary dental arch in both primary and permanent dentitions. Congenital nasal malformation (choanal atresia, midnasal stenosis or congenital pyriform aperture stenosis) is positively associated with SMMCI. The presence of an SMMCI tooth can predict associated anomalies and in particular the serious anomaly holoprosencephaly. Common congenital anomalies associated with SMMCI are: severe to mild intellectual disability, congenital heart disease, cleft lip and/or palate and less frequently, microcephaly, hypopituitarism, hypotelorism, convergent strabismus, oesophageal and duodenal atresia, cervical hemivertebrae, cervical dermoid, hypothyroidism, scoliosis, absent kidney, micropenis and ambiguous genitalia. Short stature is present in half the children. Diagnosis should be made by eight months of age, but can be made at birth and even prenatally at 18-22 weeks from the routine mid-trimester ultrasound scan. Management depends upon the individual anomalies present. Choanal stenosis requires emergency surgical treatment. Short stature may require growth hormone therapy. SMMCI tooth itself is mainly an aesthetic problem, which is ideally managed by combined orthodontic, prosthodontic and oral surgical treatment; alternatively, it can be left untreated.

Adolescents and young adult females who are hypoestrogenic need gonadal hormone therapy for sexual development, enhancement of growth, and maintenance of reproductive tissues, cyclic menses, and psychosocial health. In addition, prevention of chronic disease, specifically bone loss and possibly early heart disease, needs to be addressed in these patients. The etiology of hypopituitarism should also be considered when evaluating therapeutic options. The issues concerning estrogen replacement therapy (ERT), including the doses used and the length of therapy, are different for young patients than for postmenopausal women. The highly publicized findings of the Women's Health Initiative have identified risks of combined progestin-estrogen therapy; these risks, found in much older women, have raised questions regarding the appropriateness of ERT in adolescents with hypopituitarism and Turner syndrome. It is therefore appropriate to examine the relative risks and benefits of ERT in these populations.

Necrotizing enterocolitis in full-term infants is relatively rare. When seen, it is usually associated with perinatal asphyxia, sepsis, or specific forms of congenital heart disease. It can also be associated with endocrinopathies. In this review, a full-term infant was found to have necrotizing enterocolitis and persistent hypoglycemia. Evaluation for hypoglycemia revealed pan-hypopituitarism, and magnetic resonance imaging confirmed this diagnosis. Timely evaluation and early initiation of hormone replacement therapy is essential to minimize long-term morbidities and mortality associated with pan-hypopituitarism.

Hypoglycemia is defined by a low blood glucose level associated to clinical symptoms. Hypoglycemia may be related to treatment of diabetes, but also to drugs, alcohol, critical illness, cortisol insufficiency including hypopituitarism, insulinoma, bariatric or gastric surgery, pancreas transplantation or glucagon deficiency, or may be surreptitious. Some hypoglycemic episodes remain unexplained, and genetic, paraneoplastic and immune causes should be considered. Genetic causes may be related to endogenous hyperinsulinism and to inborn errors of metabolism (IEM). Endogenous hyperinsulinism is related to monogenic congenital hyperinsulinism, and especially to mutations of the glucokinase-activating gene or of insulin receptors, both characterised by postprandial hypoglycemia with major hyperinsulinism. In adulthood, IEM-related hypoglycemia can persist in a previously diagnosed childhood disease or may be a presenting sign. It is suggested by systemic involvement (rhabdomyolysis after fasting or exercising, heart disease, hepatomegaly), sometimes associated to a family history of hypoglycemia. The timing of hypoglycemic episodes with respect to the last meal also helps to orientate diagnosis. Fasting hypoglycemia may be related to type 0, I or III glycogen synthesis disorder, fatty acid oxidation or gluconeogenesis disorder. Postprandial hypoglycemia may be related to inherited fructose intolerance. Exercise-induced hyperinsulinism is mainly related to activating mutation of the SLC16A1 gene. Besides exceptional ectopic insulin secretion, paraneoplastic causes involve NICTH (Non-Islet-Cell Tumour Hypoglycemia), caused by Big-IGF2 secretion by a large tumour, with low blood levels of insulin, C-peptide and IGF1. Autoimmune causes involve antibodies against insulin (HIRATA syndrome), especially in case of Graves' disease, or against the insulin receptor. Medical history, timing, and insulin level orientate the diagnosis.
