Thrombotic thrombocytopenic purpura (TTP) is a rare and often fatal disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, mental status changes, and renal dysfunction. Central diabetes insipidus (CDI) is a rare disease due to anatomic lesions of the hypothalamicpituitary system associated with various underlying diseases, or trauma. We present an unusual case of TTP and CDI in a 47 year-old African American female who was admitted to our hospital with crampy abdominal pain and nausea. The patient had tachycardia, fever and hypotension. The patient subsequently became confused, developed seizures, and her renal function deteriorated. Bone marrow analysis showed adequate megakaryocytes while a peripheral smear revealed severe thrombocytopenia, polychromasia and schistocytes. The diagnosis of thrombotic thrombocytopenic purpura (TTP) was made and plasmapharesis initiated. Over the next few days, the patient developed severe polyuria with a rise in serum sodium. Central diabetes insipidus was diagnosed and DDAVP (desmopressin acetate, 1-deamino-8-D-arginine vasopressin) was given. However, DDAVP was stopped several times due to worsening thrombocytopenia. Renal function worsened and the patient expired. A review of the literature revealed only one case of report of TTP and central diabetes insipidus. Our case was the only one reporting the use of DDAVP in such a setting.

This report presents a case of cerebral venous thrombosis and venous infarction in a diabetic patient, the third in the world literature (the second in a child). An 8-year-old male was admitted to the hospital due to abdominal pain, vomiting, polydypsia, and polyuria, lasting for 4 days. Laboratory studies revealed marked hyperglycemia and ketoacidosis. Two hours after admission the child lost consciousness. Emergency computed tomography performed 3 hours after admission (4 days after the onset of symptoms) revealed hyperdensity in the vein of Galen and superior sagittal sinus, consistent with thrombosis, accompanied by bilateral venous infarction. Follow-up computed tomography performed 6 days after admission (10 days after the onset of symptoms) documented evolution of thrombosis. Magnetic resonance imaging and magnetic resonance venography performed 22 days after admission (26 days after the onset of symptoms) confirmed venous infarction and thrombosis. This report discusses possible mechanisms of cerebral venous thrombosis in diabetic hyperglycemia and stresses the importance of imaging studies despite the extreme rarity of such cases.

Thirty cases of autosomal dominant polycystic kidney disease (ADPKD) seen at King Fahd Hospital of the University, Al-Khobar over a period of eight years, were analysed with respect to clinical features, laboratory investigations, radiological findings, complications and outcome. There were 13 males and 17 females with a mean age of 45 yrs + 10.1 (range 16-65 years). There was positive family history of renal disease in 17 cases. At the time of presentation, 27 cases had abdominal pain. The other features noted were hematuria (20 cases), polyuria (10 cases), urinary tract infection (22 cases), headache (9 cases), uremia (7 cases) and nephrolithiasis (5 cases). Bilaterally palpable kidneys were present in all cases. Hypertension (17 cases) was the next common clinical finding. Other clinical features noted were hepatomegaly (5 cases) and mitral valve prolapse (5 cases). Twenty-one patients had cysts in liver and five had cysts in spleen. Varying degrees of renal failure were seen in 15 cases. Six (20%) patients progressed to end stage renal disease during the period of observation.

We report the case ofa 16 year old boy who presented with 8 months history of weight loss, 3 months history of polydypsia, polyuria and polyphagia. The child had poor growth since age of 5 years, during which time he developed recurrent abdominal pain for 4 years. A diagnosis of chronic calcific pancreatitis complicated by stunting and diabetes mellitus was made on the basis of weight/height ratio less than 5th NCHS percentile for his age, fasting blood sugar of 233mg/dl, and presence of calcifications over the pancreatic area on a plain abdominal X-ray. This case is reported due to the rarity of this condition in children. It is also the first to be seen in our hospital. It will serve to alert the Paediatrician to such clinical condition in children with chronic abdominal pain. In this case, symptoms of diabetes mellitus were the reasons for seeking medical attention and it also shows how chronic pancreatits led to insulin dependent diabetes mellitus.

It is known that type 1 diabetes mellitus (type 1 DM) may be associated with other autoimmune diseases. Recently, a patient with an association of type 1 DM and familial Mediterranean fever (FMF) was reported in the medical literature. A 10.5-year-old boy was brought to our clinic with complaints of polydipsia, polyuria and weight loss and was diagnosed as diabetic ketoacidosis due to autoimmune type 1 DM. Insulin therapy was started. Elevated thyroid antibodies associated with diffuse goiter and hypothyroidism led to the diagnosis of autoimmune thyroid disease (ATD), and elevated antiendomysial antibodies and abnormal intestinal biopsy findings led to the diagnosis of celiac disease (CD). L-thyroxine therapy and gluten-free diet were initiated accordingly. At the third-year of follow-up, acute attacks of fever, abdominal pain and chest pain developed. Laboratory investigations, which were normal between the attacks, revealed elevated erythrocyte sedimentation rate, fibrinogen, white blood cell count and pleural effusion on chest X-ray during the attacks. Molecular analysis for FMF revealed compound heterozygous M694I and V726A. The patient responded well to colchicine therapy started at a dose of 1.5 mg/day. We present the second patient with type 1 DM associated with FMF who also had ATD and CD.

A 63-year-old male was admitted to our hospital with diabetic ketoacidosis. He had flu-like symptoms 10 days before admission and developed thirst, polyuria and anorexia with 9 kg of body weight loss in a week. Plasma glucose level on admission was 983 mg/dL and HbA1c was 7.5%. Despite high levels of serum pancreatic enzymes, lack of severe abdominal pain and no morphological change of pancreas in the abdominal CT scan eliminated the complication of classical acute pancreatitis. These findings suggested the diagnosis of fulminant type 1 diabetes. However, urinary and plasma C-peptide levels showed that insulin secretion was not completely depleted at onset. Furthermore, an examination of islet-related antibodies revealed the presence of high titer anti-GAD antibody. His HLA typing showed that DRB1*0901-DQB1*0303 and A24 were present. He has been doing well with continuation of insulin therapy. Over two years after onset, his plasma C-peptide level was gradually lowered, and anti-GAD antibody was still positive. Taken together, this is a rare case of abrupt onset autoimmune type 1 diabetes with transient but apparent exocrine pancreatic impairment at onset. Similar cases should be accumulated to clarify pathophysiological similarities and/or differences between fulminant type 1 diabetes and abrupt onset autoimmune type 1 diabetes.

Familial hypomagnesemia and hypercalciuria with nephrocalcinosis is a rare autosomal recessive disease characterized by renal calcium and magnesium wasting, evolving in the progressive decrease of renal function, eventually requiring kidney transplant. Clinical findings include urinary infection, polyuria, polydipsia, cramps, tremors, convulsions, among others; these, associated to ocular and/or auditive abnormalities. We present a 4 year-old female with the syndrome, which was manifested by typical signs and symptoms in daily practice: fever, abdominal pain, polyuria and polydipsia. These symptoms may defer the diagnosis of the syndrome.

Background. Primary hyperparathyroidism in childhood is a very rare entity, often being diagnosed late after the onset of its presenting symptoms. It most commonly affects patients in their fourth decade of life and beyond. The inclusion of primary hyperparathyroidism in the differential diagnosis is necessary when evaluating patients presenting with nonspecific symptoms such as polyuria, fatigue, weight loss, abdominal pain, nausea, and vomiting. Methods. We report the case of an eleven-year-old girl presenting with three years history of headaches, visual disturbance, along with episodes of emotional lability. Neuroimaging confirmed a large posterior fossa arachnoid cyst. It was decided to manage this lesion conservatively with surveillance. Only after further hospital admissions with recurrent loss of consciousness, dizziness, and nausea to add to her already existing symptoms, a full biochemical and endocrine assessment was performed to look for more specific causes for her presentation. These pointed to a diagnosis of primary hyperparathyroidism. Conclusions. The inclusion of primary hyperparathyroidism in the differential diagnosis should be considered when evaluating paediatric patients presenting with nonspecific (neurological, gastrointestinal, and renal) symptoms in order to establish a prompt diagnosis of the disorder and to avoid severe complications of prolonged hypercalcaemia and end-organ damage.

Diabetic ketoacidosis is characterized by a serum glucose level greater than 250 mg per dL, a pH less than 7.3, a serum bicarbonate level less than 18 mEq per L, an elevated serum ketone level, and dehydration. Insulin deficiency is the main precipitating factor. Diabetic ketoacidosis can occur in persons of all ages, with 14 percent of cases occurring in persons older than 70 years, 23 percent in persons 51 to 70 years of age, 27 percent in persons 30 to 50 years of age, and 36 percent in persons younger than 30 years. The case fatality rate is 1 to 5 percent. About one-third of all cases are in persons without a history of diabetes mellitus. Common symptoms include polyuria with polydipsia (98 percent), weight loss (81 percent), fatigue (62 percent), dyspnea (57 percent), vomiting (46 percent), preceding febrile illness (40 percent), abdominal pain (32 percent), and polyphagia (23 percent). Measurement of A1C, blood urea nitrogen, creatinine, serum glucose, electrolytes, pH, and serum ketones; complete blood count; urinalysis; electrocardiography; and calculation of anion gap and osmolar gap can differentiate diabetic ketoacidosis from hyperosmolar hyperglycemic state, gastroenteritis, starvation ketosis, and other metabolic syndromes, and can assist in diagnosing comorbid conditions. Appropriate treatment includes administering intravenous fluids and insulin, and monitoring glucose and electrolyte levels. Cerebral edema is a rare but severe complication that occurs predominantly in children. Physicians should recognize the signs of diabetic ketoacidosis for prompt diagnosis, and identify early symptoms to prevent it. Patient education should include information on how to adjust insulin during times of illness and how to monitor glucose and ketone levels, as well as information on the importance of medication compliance.

About 25 million agricultural workers in the developing world suffer from at least one episode of poisoning each year, mainly by anticholinesterase-like organophosphates (OPs). The objective of this cross-sectional study was to establish the OP toxicity in 187 occupationally exposed farmers in terms of neurocognitive impairment, mental health status, clinical symptoms, diabetes, and haematological factors. The exposed group was compared to 187 healthy age-, sex-, and education-matching controls. Neurocognitive impairment was measured using the Subjective Neurocognition Inventory (SNI) and mental health status using the General Health Questionnaire-28 (GHQ-28). The subjects were also tested for fasting blood glucose (FBG), blood urea nitrogen (BUN), cholesterol (CL), triglycerides (TG), creatinine, oral glucose tolerance test (GTT), high-density lipoprotein (HDL), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP). The exposed farmers showed higher FBG (p<0.001), BUN (p=0.007), CL (p<0.001), oral GTT (p<0.001), and lower AST (p<0.001), ALP (p<0.001), and creatinine (p=0.004) than controls. The rates of anxiety/ insomnia and severe depression were also significantly higher in the farmers than in controls (p=0.015 and p<0.001, respectively). Meanwhile, the rate of social dysfunction was significantly lower than in controls (p<0.001). Disorders affecting psychomotor speed, selective attention, divided attention, verbal memory, nonverbal memory, prospective memory, spatial functioning, and initiative/energy were all lower in the farmers (p<0.001). Farmers showed clinical symptoms eczema, saliva secretion, fatigue, headache, sweating, abdominal pain, nausea, superior distal muscle weakness, inferior distal muscle weakness, inferior proximal muscle weakness, breath muscle weakness, hand tingling, foot tingling, epiphoria, polyuria, miosis, dyspnoea, bradycardia, and rhinorrhoea, which all significantly correlated with the number of working years. These findings indicate that farmers who work with OPs are prone to neuropsychological disorders and diabetes.
