The incidence of nonobstructive colonic dilatation (NCD) is unknown, but the attendant mortality associated with perforation is nearly 50%. Patients with chronic renal failure and transplant recipients may manifest many of the conditions that have been implicated in the development of NCD. Mechanical obstruction and ischemic bowel disease must be eliminated as causes for colon dilatation. Over a four-year period eight patients (mean age 50 years) were treated for presumed NCD. Six patients with a mean cecal diameter of 12.8 cm were treated initially with colonoscopy. Five patients (83%) had successful endoscopic decompression; of the three remaining patients, one underwent urgent ileocolectomy for cecal ischemia after unsuccessful endoscopic decompression, a second (cecal diameter 13 cm) had a tube cecostomy performed as an initial procedure, and the third (cecal diameter 9 cm) was managed successfully with enemas and nasogastric suction. Two deaths occurred in the series (25%), but both were unrelated to colon distension. No complications of colonoscopy were observed. The sequelae of massive NCD (cecal ischemia, perforation, and protracted sepsis) are poorly tolerated in the immunocompromised patient. Conservative management may be employed in patients with a cecal diameter of 9 cm, but urgent diagnostic and therapeutic colonoscopy is recommended for patients with a cecal diameter of 12 cm or greater. Operative tube cecostomy may be necessary if colonoscopic decompression is unsuccessful or cannot be performed.

We report 81 of 107 cases of hemolytic uremic syndrome (HUS), admitted between July 1994 and February 1996, following an outbreak of Shigella dysenteriae type 1 dysentery in Kwazulu/Natal. All patients, excluding 1, were black with a mean age of 38 months (range 1-121); 50 (61.7%) were males. The mean duration of dysentery was 11.3 days (range 1-41) and HUS 15 days (range 1-91). Most patients had acute oliguric renal failure (90.1%), 42 (51.6%) required peritoneal dialysis. Complications included encephalopathy 30 (37.0%), convulsions 12 (14.8%) and hemiplegia 2 (2.3%), gastrointestinal perforation 8 (9.9%), protein losing enteropathy 26 (32.1%), toxic megacolon 4 (4.9%), rectal prolapse 5 (6.2%), hepatitis 11 (13.6%), myocarditis 5 (6.2%), congestive cardiac failure 3 (3.7%), cardiomyopathy 3 (3.7%), infective endocarditis 1 (1.2%), septicemia 15 (18.5%), disseminated intravascular coagulation 17 (21%). Leukemoid reactions were found in 74 (91.3%) patients, hyponatremia in 56 (69.1%), and hypoalbuminemia in 67 (82.7%). Stool culture for Shigella dysenteriae type I was positive in only 7 (8.6%) patients; Shiga toxin assays were not performed. Outcome was as follows: recovery 32 (39.5%), impaired renal function 8 (9.9%), chronic renal failure 26 (32.1%), end-stage renal disease 1 (1.2%), and death 14 (17.3%) patients.

While anemia is common in patients on chronic hemodialysis (HD), spontaneous erythrocytosis is rare and can be caused by either the same conditions causing erythrocytosis in the general population or any condition specific to chronic renal failure. We present a patient illustrating this latter circumstance. A 53-year-old man with diabetic nephropathy, with no known disease causing hypoxemia started HD in April 2001. Blood hemoglobin (Hgb) level was 13.7 +/- 2.8 g/dL while his kidney function was normal (1993-1996) and after 1997, with the development of chronic kidney disease, decreased progressively to a low of 10.2 g/dL in March 2001 when erythropoietin (EPO) injections were started. Erythropoietin requirements progressively decreased because of rising Hgb. Erythropoietin was discontinued in mid-2005. Blood hemoglobin continued to rise, however, to a high value of 17.6 g/dL in February 2006. At the same time, endogenous blood EPO level was 3.6 mIU/mL, a value consistent with primary polycythemia. White blood cell and platelet counts were normal. Several small renal cysts, including 1 complex cyst, were detected by ultrasonography and computer tomography in April 2006. He refused surgical treatment. He was treated with small phlebotomies (not returning the blood in the dialyzer at the end of dialysis) and monitoring of Hgb, which decreased toward the desired range. Repeated computer tomographic scans showed a slow increase in the size of the complex cyst and several other cysts. In late 2007 Hgb started rising again, and in February 2008, while the Hgb level was 16.4 g/dL, the endogenous serum EPO level was 726 mIU/mL (upper normal limit 31.5 mIU/mL). Intermittent phlebotomies were reinstituted. He subsequently developed multiple vascular catastrophes and expired from ischemic bowel disease in September 2008. Acquired cystic disease of the kidneys should be considered in HD patients who develop spontaneous erythrocytosis. The risks of acquired cystic disease include, in addition to the development of malignancy, vascular events from elevated Hgb.

This review is an overview of systemic conditions that can be associated with peripheral nervous system dysfunction. Children may present with neuropathic symptoms for which, unless considered, a causative systemic condition may not be recognized. Similarly, some systemic conditions may be complicated by comorbid peripheral neuropathies, surveillance for which is indicated. The systemic conditions addressed in this review are critical illness polyneuropathy, chronic renal failure, endocrine disorders such as insulin-dependent diabetes mellitus and multiple endocrine neoplasia type 2b, vitamin deficiency states, malignancies and reticuloses, sickle cell disease, neurofibromatosis, connective tissue disorders, bowel dysmotility and enteropathy, and sarcoidosis. In some disorders presymptomatic screening should be undertaken, while in others there is no benefit from early detection of neuropathy. In children with idiopathic peripheral neuropathies, systemic disorders such as celiac disease should be actively excluded. While management is predominantly focused on symptomatic care through pain control and rehabilitation, some neuropathies improve with effective control of the underlying etiology and in a small proportion a more targeted approach is possible. In conclusion, peripheral neuropathies can be associated with a diverse range of medical conditions and unless actively considered may not be recognized and inadequately managed.

Sodium polystyrene sulfonate (SPS) is used to reduce intestinal potassium absorption in hyperkalemia during conservative management of chronic renal failure in infants. Milk can be pretreated by SPS to reduce the risk of enteropathy associated with oral or rectal administration. We report the case of an infant for whom this pre-treatment has been implemented. The objective of this work was to define the hospital procedure for the pre-treatment of milk by the SPS. This pre-treatment involves both a drug and infant milk. Each product has its own regulation and their processes do not normally cross each other. The roles of each contributor were therefore defined: prescription of pre-treated milk (dose of SPS and volume of milk) by the physician, dispensing of SPS by the pharmacist, delivery of milk by the milk kitchen staff, pre-treatment by a nurse and administration by a nursing auxiliary. The preparation of the bottles is as follows: placing approximately 1g of SPS per 100mL of milk in contact, stirring, resting in the refrigerator for one hour, taking the supernatant to be administered. In the reported case, serum potassium levels were reduced from 5.57mmol/L before treatment to 4.53mmol/L after treatment, in line with the 20% decrease found in the literature. This method of administration is beneficial in terms of tolerance and acceptability. The preparation is simple and allows going back home under treatment.
