A Rare Case of Wirsung Duct Duplication with Chronic Pancreatitis.

Wirsung duct duplication is a very rare condition that can lead to chronic pancreatitis.

The Urine Calcium/Creatinine Ratio and Uricemia during Hyponatremia of Different Origins: Clinical Implications.

Background: Chronic hyponatremia is known to be associated with osteoporosis. It has been shown that chronic hyponatremia increases bone resorption in an attempt to release body stores of exchangeable sodium by different mechanisms. We wanted to know the calciuria of patients with hyponatremia of different origins.

Barefoot Running: Between Fashion and Real Way to Prevent Joint Osteo Lesions?

Background And Objectives: Running has gone from a vital necessity for the man to a playful sport. Different rheumatic and orthopedic pathologies have appeared, in front of which the shoe industry has reacted by creating reinforced shoes that are supposed to overcome the induced lesions. Several years later, the trend toward reinforcement has gone toward minimalism, which is the absence of reinforcement, that is, a more natural race.

Estimated Daily Urine Volume and Solute Excretion from Spot Urine Samples to Guide the Therapy of Hyponatremia in SIADH.

In hyponatremia, due to the inappropriate secretion of antidiuretic hormone (SIADH), a high versus low solute intake will affect the urine volume (UV) and, hence, the SNa level. The clinical implication of the fractional solute excretion is presented. : In 35 normal controls and 24 patients with SIADH and urine osmolality higher than serum osmolality, we compared exact solute intake obtained from 24 h urine collection, with the estimated value obtained on a urine morning spot sample by the formula: The exact UV was compared with the estimated value given by the formula: In 65 patients with chronic SIADH, from which a morning spot urine sample was available, we determined the estimated fluid and solute intake.

Idiopathic Ileo-Ileo-Cecal Intussuception in a 25-Year-Old Female.

BACKGROUND Intussusception is defined as the penetration or telescoping of a segment of bowel into a more distal segment. Intussusception is a common cause of small bowel obstruction, especially in children. However, this finding is much less common in adults.

Severe Solute Depletion in Patients with Hyponatremia Due to Diuretics Despite Biochemical Pictures Similar Than Those Observed in the Syndrome of Inappropriate Secretion of Antidiuretic Hormone.

Background/aims: Hyponatremia secondary to distal diuretics intake could have a biochemical picture similar to the one observed in the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). In these patients, water retention is considered to be the main causal factor and solute depletion a secondary one.

Methods: We compared the level of cation (Na + K) depletion and water balance in patients with high or low uric acid levels (< 4 mg/dL or 238 µmol/L) or with high or low (< 30 mg/dL or 5 mmol/L) urea levels.

Actual Therapeutic Indication of an Old Drug: Urea for Treatment of Severely Symptomatic and Mild Chronic Hyponatremia Related to SIADH.

Oral urea has been used in the past to treat various diseases like gastric ulcers, liver metastases, sickle cell disease, heart failure, brain oedema, glaucoma, Meniere disease, etc. We have demonstrated for years, the efficacy of urea to treat euvolemic (SIADH) or hypervolemic hyponatremia. We briefly describe the indications of urea use in symptomatic and paucisymptomatic hyponatremic patients.

Hepatitis C genotype 4 response rate to pegylated interferon and ribavirin treatment in Belgium is similar to genotype 1.

Background And Aims: Patients with genotype 4 (G4) chronic hepatitis C from the Middle East respond better to treatment than genotype 1 (G1) patients. There are few data on the response rates to treatment of G4 patients living in Western Europe. Many G4 patients in Belgium originate from Central Africa, and their response to treatment seems lower.

Low sodium excretion in SIADH patients with low diuresis.

Unlabelled: It is well known that during low diuresis or low effective circulating volume, salt excretion is low. The aim of this study was to find out whether salt excretion, expressed as either urinary sodium concentration (UNa) or fractional sodium excretion (FENa), and the combined use of FENa and fractional urea excretion (FEurea) still differentiate between hyponatremic SIADH and hyponatremic salt depletion (SD) patients when diuresis is low. The relationships between UNa, FENa and diuresis, indirectly estimated by the urinary to plasma creatinine ratio (U/P creat), were studied in 42 hyponatremic SIADH patients, 21 hyponatremic SD patients and 66 normonatremic controls (CO) of similar age and sex ratio.

Solute loss plays a major role in polydipsia-related hyponatraemia of both water drinkers and beer drinkers.

Background: Polydipsia-related hyponatraemia is generally considered an acute dilutional state.

Aim: To determine whether solute loss plays a role in the pathogenesis of polydipsia-related hyponatraemia.

Design: Prospective uncontrolled study.

Utility and limitations of biochemical parameters in the evaluation of hyponatremia in the elderly.

We evaluated in 110 consecutive elderly hyponatremic patients the value of traditional clinical and biochemical data and the place of a test infusion of 2 liters isotonic saline over 24 hours, in establishing the etiology of the hyponatremia. The causes of hyponatremia were as follows: 31% SIADH patients, 23% patients with hyponatremia due to diuretics, 18% potomania patients, 15% salt depleted patients, 5% salt depleted SIADH patients, 5% patients with a salt loosing syndrome and 3% patients with hyponatremia of unknown origin. Several salt depleted (SD) and SIADH patients could be confounded.

Treating the syndrome of inappropriate ADH secretion with isotonic saline.

It has been widely accepted that there is little use for saline treatment in the syndrome of inappropriate secretion of ADH (SIADH). However, having observed that most SIADH patients increased their plasma sodium (PNa) after 2 l isotonic saline over 24 h, we investigated whether urine osmolality or the sum of urinary sodium and potassium (UNa + K) predicted this response, in 17 consecutive patients with chronic SIADH. The initial measure of urinary sodium plus potassium (UNa + K t0) was weakly correlated to the change in PNa (DPNa) after infusion (r = -0.

Combined fractional excretion of sodium and urea better predicts response to saline in hyponatremia than do usual clinical and biochemical parameters.

Background: The treatment of hyponatremic patients requires physicians to make a therapeutic choice between saline infusion and water restriction. Therefore, they need readily available and reliable parameters to facilitate making that choice. This study was designed to determine whether the use of clearance ratios can help clinicians recognize saline-responding hyponatremic patients.

Granulopoiesis inhibition in acute inflammation: comparative studies in healthy and leukaemic mice.

It was demonstrated previously that mice undergoing an inflammatory reaction induced by subcutaneous (SC) implantation of copper rods, produce humoral factors that initially enhance, but subsequently inhibit, diffusion chamber (DC) granulopoiesis. This provided evidence that granulopoiesis is under the control of both humoral stimulators and inhibitors. In order to test the granulopoietic regulatory mechanism in leukaemic mice, we investigated the regulatory role of granulopoietic humoral inhibitors during in vivo granulopoiesis.
