A sixty-year-old man experienced successively over two years several episodes of circulatory collapse and meningeal hemorrhage, a myocardial infarction, an episode of ketoacidosis and a seizure before acute abdominal pain with fever related to the sudden, partial, necrosis of his tumor, led to the discovery of a pheochromocytoma. This observation exemplifies the multiple clinical aspects and diagnostic pitfalls of this secreting tumor. It underscores the misleading nature of normotensive pheochromocytomas.

The association of celiac disease, epilepsy and occipital calcifications with initial clinical manifestations of epilepsy during the first two decades of life with an often progressive and variable course and clinical expression of malabsorption has recently been described. Two cases of celiac disease with occipital calcifications and a presentation with neurologic symptoms in adulthood are reported. The first case is that of a 40-year-old male who presented recurrent and alternating pure brachial monoparesis and later acute abdominal pain following which celiac sprue was diagnosed. The second case is that of a 53-year-old woman diagnosed with celiac sprue 20 years before, presenting permanent myoclonus in the lower limbs which were progressive in severity, ataxic march and generalized tonoclonic seizures. Both patients had bilateral occipital calcifications on CT and celiac disease was demonstrated on biopsy. The first case also showed marked signal alteration in the white matter on MRI. Celiac disease with cerebral calcifications presents also in adulthood with atypical clinical manifestations. Suspicion of celiac disease may be confirmed by non-invasive methods such as antigliadin and antiendomysium antibody determination. CT imaging is characteristic.

Certain of the hepatic porphyrias are classified as belonging to the acute hepatic prophyrias, namely acute intermittent porphyria (AIP), variegate porphyria (VP), hereditary coproporphyria (HCP) and ALA-dehydrase deficiency. The common feature of all acute hepatic porphyrias is the sudden onset of neurological symptoms. The whole syndrome consists of acute abdominal pain crises with autonomic dysfunction, global or focal central nervous system involvement and a predominantly motor polyneuropathy. Mono- or oligosymptomatic manifestations of acute porphyrias occur and are probably underestimated. The laboratory diagnosis of porphyria depends on the measurement of porphyrin precursors in urine, whereas the measurement of porphyrins in urine and feces is essential for evaluation of the porphyria type. Enzyme measurements are used to identify asymptomatic family members whose quantitative excretions of porphyrins are normal. At present the pathogenesis of neurological manifestations of acute porphyrias remains an unsettled question. The major hypotheses are discussed in this paper. The most important precipitating factor in acute hepatic porphyrias is drug ingestion. As many new drugs have not been in use for sufficiently long periods to assess their porphyrogenic activity, it is safer to avoid drugs in patients with porphyria. The most effective treatment of porphyria attacks is the administration of heme. Among the porphyria patients with epileptic seizures requiring antiepileptic medication, treatment with bromides should be taken into consideration.

We present a rare case of acute pancreatitis associated with temporal lobectomy due to intractable seizure in a 23-year-old man. The patient underwent elective right temporal lobectomy and hippocampectomy. Severe upper abdominal pain occurred just 10 hours after surgery. The diagnosis of acute pancreatitis was based on the elevation of serum amylase and lipase levels, and the findings of abdominal computerized tomography. Other possible causative factors of acute pancreatitis including alcohol, biliary tract stone, hypertriglyceridemia, hypercalcemia, hyperparathyroidism, biliary dysmotility and autoimmune disease were excluded by a series of examinations. The possibility of drug-induced pancreatitis was very low in this patient. The patient was discharged after supportive treatment. No recurrence of seizure or abdominal pain was noted in the three months after discharge. Acute abdominal pain after brain surgery deserves clinical evaluation for acute pancreatitis.

A 19 year-old woman admitted to Emergency Department with hypotension, sudden loss of vision and acute abdominal pain. Ultrasound and computed tomography demonstrated an occipital infarct in brain and ruptured intraperitoneal cyst of hydatid liver disease. Urgent laparotomy was performed and it included aspiration of cyst contents, peritoneal washing and drainage. Her vision loss improved by 15 hours postoperatively but generalized seizures were started. Weakness in all extremities was present. Cranial MRI demonstrated ischemia in the areas of middle, posterior and anterior cerebral arteries. She was discharged from the hospital with severe neurological deficits (unable to walk, not able to eat herself). Neurological deficits were improved with physiotherapy after two years. There was no recurrence of hydatid cysts in the follow-up of three years. We assumed that anaphylaxis after intraperitoneal rupture of hydatid liver cyst resulted with hypotension and reduced cerebral perfusion, caused the acute vision loss and other neurological symptoms. This unusual presentation of intraperitoneal rupture should be kept in mind particularly in endemic areas of hydatid disease.

Thrombotic microangiopathy (TMA) is a rarely reported complication of acute pancreatitis. The prognosis is generally good, if diagnosis is made early and treatment is adequate. We present the case of a 74-year-old man who visited our emergency department due to acute abdominal pain. He had no history of alcohol abuse or pancreatitis. Blood tests indicated elevated lipase and amylase. An abdominal computerized tomography (CT) indicated mild pancreatitis. After admission, the patient suffered a seizure and developed anemia, thrombocytopenia, elevated lactic dehydrogenase (LDH) and elevated unconjugated bilirubin. A peripheral blood smear indicated fragmented red blood cells. We diagnosed the patient as having TMA. After plasma exchange and plasma infusion therapy, the LDH and platelet levels gradually improved. A differential diagnosis of disseminated intravascular coagulation (DIC) and TMA following pancreatitis is necessary because of the different treatment strategies. Our patient had a good prognosis following therapy for TMA. Such therapy may include plasma exchange, plasma infusion, corticosteroid therapy and splenectomy.

The rate of reporting of childhood Churg-Strauss syndrome (CSS) has increased lately because of either increased awareness to the disease or a real increase in incidence. It is defined as one of the antineutrophil cytoplasmic antibody-associated vasculitides, but the antineutrophil cytoplasmic antibody positivity is less reported in pediatric cases. The cause of CSS remains unknown. Several lines of evidence suggest genetic predisposition, which may entail inherited tendency to dysregulation of the cellular immune system. With the addition of leukotriene receptor antagonists to the treatment regimen of asthma, an association to CSS was presumed. However, the nature of this relationship remains to be elucidated. In addition, some environmental factors seem to provoke transient effects that resemble the disease. Patients' symptoms are defined by various degrees of eosinophilic inflammation and necrotizing vasculitis, which may affect any organ. Three clinical stages have been described in the clinical evolution of CSS: prodromal phase involving allergic rhinitis and asthma (usually without family history of atopy), a second phase that involves peripheral eosinophilia and eosinophilic tissue infiltration, and the hallmark of the final phase is systemic vasculitis. Pulmonary disease is a central feature of pediatric CSS, but other manifestations include skin lesions, testicular pain, hypertension, seizures, and nephropathy. More subtle presentations in children include cervical lymphadenopathy, acute abdominal pain, deep venous thrombosis, oral ulceration, multiple colonic ulcers, chorea, bilateral optic neuropathy, and retinal artery occlusions. Churg-Strauss syndrome patients usually respond well to corticosteroid therapy. Several trials reported additional benefit from cyclophosphamide, azathioprine, and methotrexate, whereas the therapeutic effects of etanercept, plasma exchange, and intravenous immunoglobulin therapy are controversial. The relapse rate is approximately 25% to 30%, but corticosteroids have significantly increased survival, which now approaches greater than 75% at 5 years. However, there is limited information about survival or long-term outcome in childhood.

Porphyrias are a group of rare disorders caused by enzyme defects in haem biosynthesis pathway. Acute intermittent porphyria is the most common hepatic porphyria. The disorder presents with severe neuropathic abdominal pain that can be accompanied by a wide range of gastrointestinal, psychiatric and neurological symptoms, making the diagnosis clarification very challenging. We report a case of a 27-year-old female patient who presented with acute abdominal pain, vomiting and marked hyponatremia, developed seizures and disorientation, and eventually required intensive care unit treatment to maintain breathing. Her symptoms were initially misinterpreted as a functional gastrointestinal disorder, thus delaying the needed specific treatment. She was diagnosed a week after the initial hospital admission, and her condition improved after receiving treatment with intravenous glucose and haemin. For patients with acute neurovisceral attacks, early clinical recognition is essential. Severe hyponatremia, urine that develops orange colour on exposure to light and gastrointestinal symptom combination with neurologic symptoms are three valuable clues that may lead to the right diagnosis faster. Pathophysiology of hyponatremia in case of acute intermittent porphyria in only partly understood and can be associated with syndrome of inappropriate antidiuretic hormone secretion, gastrointestinal or renal sodium loss.

Acute Intermittent Porphyria (AIP), an autosomal dominant inborn error of heme metabolism, typically presents in adulthood, most often in women in the reproductive age group. There are limited reports on the clinical presentation in children, and in contrast to the adults, most of the reported pediatric cases are male. While acute abdominal pain is the most common presenting symptom in children, seizures are commonly seen and may precede the diagnosis of AIP. As an example, we report a 9year old developmentally normal pre-pubertal boy who presented with acute abdominal pain, vomiting and constipation followed by hyponatremia, seizures, weakness and neuropathy. After a diagnostic odyssey, his urine porphobilinogen was found to be significantly elevated and genetic testing showed a previously unreported consensus splice-site mutation IVS4-1G>A in the HMBS gene confirming the diagnosis of AIP. Here, we discuss the clinical presentation in this case, and 15 reported pediatric cases since the last review 30years ago and discuss the differential diagnosis and challenges in making the diagnosis in children. We review the childhood-onset cases reported in the Longitudinal Study of the Porphyrias Consortium. Of these, genetically and biochemically confirmed patients, 11 of 204 (5%) reported onset of attacks in childhood. Most of these patients (91%) reported recurrent attacks following the initial presentation. Thus, AIP should be considered in the differential diagnosis of children presenting with unexplained abdominal pain, seizures, weakness and neuropathy.
