We report herein the cases of two women, aged 34 years and 39 years, respectively, found to have hyperinsulinemic hypoglycemia after presenting with a history of episodes of temporary loss of consciousness, nausea, and fainting. Under the suspected diagnosis of insulinoma, localization procedures were carried out, but no tumor was found. In both patients, a definite gradient in insulin concentration was found in the pancreas by percutaneous transhepatic or intraoperative portal venous sampling, and a misdiagnosis of insulinoma of the pancreatic body was made. During exploratory laparotomy no tumor was palpable in the pancreas, and intraoperative ultrasonography showed no low echoic mass in the pancreas. A distal pancreatectomy was performed in both patients, and histopathological examination of the resected specimens revealed graded slight hyperplasia of the islet cells.

Case report of a 25-year-old primigravida who sustained a necrosis of the anterior pituitary gland after a haemorrhagic Caesarean section. The diagnosis was delayed, as the early symptoms (apathy, anorexia, nausea, orthostatic hypotension and hypoglycaemia) were imputed to more usual causes.

In patients with type 1 or type 2 diabetes mellitus disturbances of the gastrointestinal transit are well recognized. In decreasing order of frequency, transit disturbance through the colon, stomach, small intestine and esophagus as well as altered motility of the gallbladder occur. Acute changes of blood glucose concentrations have a major, however, reversible influence on motility in various parts of the intestinal tract. Long-term hyperglycemia may influence the incidence of gastrointestinal involvement via the occurrence of neuropathic changes of the autonomic nervous system. Early satiety, nausea, vomiting, weight loss, constipation, diarrhea and epigastric pain are often reported. These symptoms and recurrent episodes of hypoglycemia or prolonged hyperglycemia can result from intestinal transit disturbances.

We compared clinical presentation and course of exercise-associated hyponatremia with heat exhaustion among summertime hikers in Grand Canyon National Park. Cases were selected from among hikers who requested medical help from the National Park Service Emergency Medical Service (EMS) or who presented to the medical clinic on the rim of the canyon with complaints related to exercise in the heat. Of 44 patients who had serum samples analyzed, 7 had hyponatremia with clinically significant symptoms and serum sodium levels <130 mmol/L: 3 had grand mal seizures, 2 had other major central nervous system disorders, and 2 had minor neurological symptoms. Seizures and change of mental status distinguished hyponatremia, (P = 0.0002). Indirect evidence suggests that hyponatremic patients were hyperhydrated. Other common symptoms included nausea, vomiting, headache, and dizziness, but these symptoms did not predict the level of serum sodium. When exercise in the heat is prolonged, hyponatremia is suggested either by altered mental status or by seizures without hyperpyrexia or hypoglycemia. No mortality or long-term morbidity occurred in any of these cases of hyponatremia.

Acute fatty liver of pregnancy (AFLP), rare and potentially fatal disease, is considered as obstetric emergency. The perinatologist must be familiar with this complication of pregnancy because early diagnosis, prompt delivery and supportive care is the mainstay of therapy. When pregnant woman has nausea or vomiting, abdominal pain and jaundice, increased transaminase activity, coagulopathy and hypoglycemia during third trimester AFLP should be suspected. Mothers who have experienced AFLP must be informed of the possibility recurrence and undergo close surveillance in the next pregnancy.

Objective: To investigate the early recognition and management of acute fatty liver of pregnancy (AFLP) to improve the maternal and fetal survival.Study Design: Eight cases presenting with AFLP managed in our hospital during the past 212 years were studied retrospectively with emphasis on presenting symptoms, laboratory findings, and the time for liver biopsy. Also, to report the maternal and fetus outcomes in such cases.Result: The mean gestational age at onset was 34 +/- 2 weeks (range 30-37 weeks). All cases were primigravida. In the early stages, all presented with malaise, nausea, vomiting, and epigastric distress followed by jaundice in the third trimester of pregnancy. Three of eight presented with polyuria and polydipsia. Laboratory findings: all had raised transaminases and serum bilirubin (2.9-29.9 mg/dL), hypoalbuminemia (22.4-30 g/L), hypofibriogenemia (< 180 mg/dL), prolonged prothrombin time, and prolonged partial thromboplastin time. Maternal complication was frequent, including hepatic encephalopathy (6), ascites (6), hypoglycemia (5), hematemesis (2), postpartum hemorrhage (5), and preeclampsia (4). Cesarean was performed in 3 cases. One mother died of fulminant hepatic failure, the other cases were survival. There were no fetal deaths. Liver biopsy was done in 8 cases. It is suggested that percutaneous liver biopsy should not be done until the coagulation tests become normal, the amounts of ascites decrease and platelet counts increase after delivery.Conclusion: With increasing awareness, especially in the early recognition of AFLP cases and prompt progressive management, including early termination of pregnancy, and using large-dose infusion of fresh frozen plasma or albumine alternatively, the prognosis of AFLP is obviously improved.

Although migraine is the main chronic headache in childhood and adolescence, it remains extensively misdiagnosed. Schematically, migraine is a severe headache evolving by stereotyped attacks frequently associated with marked digestive symptoms (nausea, vomiting, abdominal pain). Throbbing pain, sensitivity to sound, and light (and sometimes odors) are frequent additional symptoms. The attack is sometimes preceded by a visual or sensory aura. Rest brings relief, and sleep often ends the attack. Childhood migraine prevalence varies between 5 and 10%. Migraine episodes are frequently triggered by several factors: emotional stress (school pressure, vexation, excitement, upset), hypoglycemia, lack or excess of sleep (weekend migraine), sensory stimulation (loud noise, bright light, strong odor, heat or cold, etc.), sympathetic stimulation (sport, physical exercise). Attack treatments must be given at an early stage, oral ibuprofen (10 mg/kg) being particularly recommended. If the oral route is not available because of nausea or vomiting, rectal or nasal routes have then to be used. Non-pharmacological treatments (biofeedback and interventions combining progressive muscle relaxation) have demonstrated good efficacy as prophylactic measures. Daily prophylactic pharmacological treatments are prescribed as the second line after failure of non-pharmacological treatments.

A 39-year-old man with myotonic dystrophy consulted our hospital for nausea, vomiting and dizziness that occurred after 75 g oral glucose tolerance test (OGTT). Reexamination of OGTT revealed remarkable hyperinsulinemia (622 microU/ml) followed by reactive hypoglycemia (50 mg/dl) and such hypoglycemic symptoms as nausea, vomiting, dizziness and palpitation. DNA analysis of the circulating lymphocytes revealed increased (1,500 times) number of cytosine-thymine-guanine (CTG) trinucleotide repeats in myotonic dystrophy protein kinase (DM kinase) gene. Gel chromatographic analysis of the plasma in combination with sensitive enzyme immunoassay of insulin revealed that the ratio of proinsulin to total immunoreactive insulin was elevated at fasting (12.9%), and was decreased to 8.9% at 60 min after glucose administration. These findings may indicate that biologically active authentic insulin was predominantly secreted after glucose administration in the present case. This is the first case report of myotonic dystrophy with hyperinsulinemia associated with reactive hypoglycemia induced by oral glucose administration.

We report a case of a seventy-year-old woman with syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and adrenal insufficiency induced by Rathke's cleft cyst. She experienced nausea, vomiting, diarrhea, and headache and disturbance of consciousness induced by hyponatremia at a serum sodium level of 100 mEq/l. In spite of severe hyponatremia, urinary sodium excretion was not suppressed and serum osmolality (270 mOsm/kg) was lower than urine osmolality (304 mOsm/kg), and arginine vasopressin (AVP) remained within normal range. SIADH was diagnosed because she was free from other diseases known to cause hyponatremia such as dehydration, cardiac dysfunction, liver dysfunction, renal dysfunction, hypothyroidism, and adrenal insufficiency. Cranial computed tomographic (CT) scan and cranial magnetic resonance (MR) imaging showed a cystic lesion of approximately 2 cm in diameter in the pituitary gland. These images suggested that the cystic lesion was a Rathke's cleft cyst, which was the cause of SIADH. Water restriction therapy normalized her serum sodium concentration and improved her symptoms. After one year, she suffered from general fatigue, appetite loss, fever, and body weight loss (5 kg/2 months). She had neither hypotension nor hypoglycemia, but her serum sodium level was low and serum cortisol, ACTH, and urine free cortisol were very low. Therefore, secondary adrenal insufficiency was suspected and diagnosed by stimulation tests. After start of hydrocortisone replacement therapy (10 mg/day), her symptoms disappeared. In conclusion, Rathke's cleft cyst should be kept in mind as a potential cause in a patient with SIADH, hypopituitarism, and/or adrenal insufficiency.

In childhood and adolescence, migraine is the main essential chronic headache. This diagnosis is extensively underestimated and misdiagnosed in pediatric population. Lacks of specific biologic marker, specific investigation or brain imaging reduce these clinical entities too often to a psychological illness. Migraine is a severe headache evolving by stereotyped crises associated with marked digestive symptoms (nausea and vomiting); throbbing pain, sensitivity to sound, light are usual symptoms; the attack is sometimes preceded by a visual or sensory aura. During attacks, pain intensity is severe, most of children must lie down. Abdominal pain is frequently associated, rest brings relief and sleep ends often the attack. The prevalence of the migraine varies between 5p.100 and 10p.100 in childhood. At childhood, headache duration is quite often shorter than in adult population, it is more often frontal, bilateral (2/3 of cases) that one-sided. Migraine is a disabling illness: children with migraine lost more school days in a school year, than a matched control group. Migraine episodes are frequently triggered by several factors: emotional stress (school pressure, vexation, excitement: upset), hypoglycemia, lack of sleep or excess (week end migraine), sensorial stimulation (loud noise, bright light, strong odor, heat or cold.), sympathetic stimulation (sport, physical exercise). Attack treatments must be given at the early beginning of the crisis; oral dose of ibuprofen (10mg/kg) is recommended. If the oral route in not available when nausea or vomiting occurs, the rectal or nasal routes have then to be used. Non pharmacological treatments (biofeedback and interventions combining progressive muscle relaxation) have shown to have good efficacy as prophylactic measure. Daily prophylactic pharmacological treatments are prescribed in second line after failure of non-pharmacological treatment.
