Intracellular magnesium concentrations in dogs with gastric dilatation-volvulus.

OBJECTIVE: To quantify and compare intracellular magnesium concentrations (Mgi) in clinically normal dogs (control dogs) and dogs that have gastric dilatation-volvulus (GDV dogs) and to determine whether there is a difference in Mgi and serum magnesium concentrations (Mgs) between GDV dogs with and without cardiac arrhythmias. ANIMALS: 41 control dogs and 21 GDV dogs. PROCEDURE: Rectus abdominis muscle specimens were obtained from control and GDV dogs for determination of Mgi. Blood samples were obtained from GDV dogs for determination of Mgs, and dogs were monitored for 48 hours for cardiac arrhythmias. Muscle specimens were frozen at -40 C, oven dried at 95 C, and digested with concentrated nitric acid. Multielemental analyses were performed by simultaneous/sequential inductively coupled plasma-atomic emission spectroscopy with fixed-cross flow nebulization. The Mg, was standardized to sulfur content to correct for the amount of fat and fascia in the muscle specimen. Mean (+/- SEM) values were recorded in parts per million (ppm). Results-There were no significant differences in Mgi between control (627 +/- 11.1 ppm) and GDV (597 +/- 20.5 ppm) dogs, in Mgi between GDV dogs with (590 +/- 34 ppm) and without (584 +/- 29 ppm) cardiac arrhythmias, and in Mgs between GDV dogs with (1.77 +/- 0.26 ppm) and without (1.51 +/- 0.09 ppm) cardiac arrhythmias. There was no correlation between Mgs and Mgi (R2 = 0.0001). CONCLUSIONS AND CLINICAL RELEVANCE: Results indicate that Mg depletion is not pathophysiologically important in dogs with GDV and does not play a role in the cardiac arrhythmias detected in these patients.

[Vascular ectasias of the gastric antrum as the cause of chronic digestive hemorrhage. Presentation of a case].

Digestive hemorrhages are one of the syndromes, that frequently attracts the attention of the gastroenterologist-endoscopist. Sometimes it's not evident during upper endoscopy study and course with a contrast radiological scan. In the last years a vascular pathology has been seen which is responsible of high digestive hemorrhages. It is manifested by melaena and is originated by vascular ectasias, which are vascular dilatations present in the stomach or right colon during various accompanying pathologies like hepatic cirrhosis with portal hypertension, cardiac valvulopaties, etc. Here we present a 61 year old woman with a history of chronic hepatopathy of cirrhotic type and imprecise etiology (diagnosed since 1983). Approximately two years ago (1996-1997) she has been presenting digestive hemorrhages and she has been transfused in different occasions because she had severe anemia. Diffuse vascular ectasias in the distal region of the antrum and in part of the gastric body were observed during duodenoscopy and colonoscopy with signs of active hemorrhage and similar non-bleeding lesions in the colon. Pyruvic transaminase was normal; HBV and HCV -markers were -negative. Ultrasound analysis was normal. The diagnosis at the discharge from Hospital was Diffuse Vascular Ectasias of the Gastric Antrum and part of the gastric body, caecum and right colon, secondary to hepatic cirrhosis. She was admitted again at the hospital because of new upper digestive hemorrhages and surgery was indicated. Gastric resection was performed with promising results. This case is analyzed and the pathology is results.

Chronic idiopathic intestinal pseudo-obstruction.

Chronic idiopathic intestinal pseudo-obstruction (CIIP) is a rare heterogeneous clinical syndrome characterized by recurrent episodes of symptoms and signs of intestinal obstruction in the absence of a mechanically obstructing lesion. Dilatation of other viscera, such as the renal pelvis, ureter or urinary bladder, is identified in a minority of patients. We report the cases of two patients with CIIP presenting with abdominal fullness and constipation. Radiologic examination of the first patient revealed dilatation of the esophagus, stomach, duodenum and bowel loops up to the ascending colon. The nerve conduction velocity study of the right extremities revealed polyneuropathy and urinary bladder manometry revealed poor sensation. The patient had been admitted to our hospital three times for symptomatic relief within the prior six months. During the last admission, his symptoms persisted without response to medical treatment. Soon after discharge, the patient underwent surgery at another hospital and died of nutritional problems. The second patient was transferred to our hospital after an exploratory laparotomy was performed one month earlier. A radiographic examination revealed distention of the stomach, duodenum, small intestine and ascending colon, as well as bilateral hydronephrosis. Rheumatologic examination revealed no evidence of autoimmune disorder. The patient also had heavy proteinuria due to minimal change disease that was proven by renal biopsy. After receiving prokinetic, cathartic and corticosteroid medication for kidney disease, symptoms improved, but hydronephrosis persisted.

[Surgical treatment of morbid obesity--gastric banding].

Approximately 16% of male and 20% of female of the age from 20 to 65 years are obese in the Czech Republic. The restrictive bariatric procedure of stomach--gastric banding (GB) is one of possibilities to cure the morbid obese patients after failure of conservative therapy. The ratio of complications (5-18%) after GB presenting in various papers is comparable with the ratio of complications (4-23%) in others bariatric procedures. From 1993 to 1999, 517 morbid obese patients (mean BMI 51.1) underwent laparoscopic nonadjustable gastric banding (LNGB) at 1st Surgical Department, Charles University Teaching Faculty Hospital in Prague. As the early complications (during hospitalization) offered swelling of the gastric mucous in the place of GB in 5.6% (n = 29), the oesophagitis, the gastritis or the gastric ulcer in 1.5% (n = 9) and perforation of the stomach wall in 0.6% (n = 3). As the late complications offered the bleeding from peptic ulcer in 0.4% (n = 2), sequential migration of gastric band through the stomach wall inside in 0.6% (n = 3) and the slippage of anterior stomach wall or the dilatation of the pouch above gastric bandage in 5.1% (n = 26). The serious complications in 6.3% (n = 32) claimed surgical procedures. Other complications in 7.5% (n = 39) have been treated conservatively. The 86% (n = 446) of obese patients after LNGB were without complications.
