1/7. Acute tubulointerstitial nephritis following intravenous immunoglobulin therapy in a male infant with minimal-change nephrotic syndrome.A boy aged 4 years with nephrotic syndrome (NS) was referred to our hospital because of the third relapse of NS. Hypogammaglobulinemia associated with massive proteinuria was observed at the presentation. Residual urinary tract infection required intravenous piperacillin and immunoglobulin therapy (IVIG). Soon after IVIG, he complained of high fever with chills, bilateral knee joint pain, dry cough and chest discomfort. Although he did not develop renal insufficiency, a transient increase in the urinary beta2-microglobulin and decrease in the serum complement hemolytic activity were observed. These clinical manifestations spontaneously ceased. A percutaneous renal biopsy for his NS performed 19 days after the episode of allergic reaction revealed tubulointerstitial nephritis (TIN) with marked eosinophil infiltrates. Glomeruli showed minor glomerular abnormalities. Renal complications associated with IVIG treatment have been reported to date, however, acute TIN has rarely been seen.- - - - - - - - - - ranking = 1keywords = chill (Clic here for more details about this article) |
2/7. Recurrent urinary tract infections and genitourinary tract abnormalities in the Imerslund-Grasbeck syndrome.Two Imerslund-Grasbeck patients who presented with recurrent urinary tract infections and genitourinary abnormalities are described. The patients were evaluated with abdominal ultrasounds, voiding cystourethrograms, and Schilling tests. Each patient had large postvoid residual urine secondary to a motor-neurogenic bladder. One had a duplication of the distal urethra manifesting as two meatal openings. There was lack of urinary excretion of radioactive vitamin B12 on Schilling tests in both patients. patients with Imerslund-Grasbeck syndrome may be predisposed to urinary tract infections because of incomplete bladder emptying. Complete physical and radiological examinations of the genitourinary tract should be performed.- - - - - - - - - - ranking = 2keywords = chill (Clic here for more details about this article) |
3/7. Renal fungal ball: an unusual sonographic finding.Fungal infections of the urinary tract tend to occur in the drainage structures instead of the renal parenchyma. In patients with systemic candidiasis, the kidney is vulnerable to the formation of cortical abscesses or obstructive intrarenal masses ("fungal balls"), usually at the ureteropelvic junction. We describe the case of a boy who presented with dysuria, fever, and chills. Sonographic examination showed mild enlargement of both kidneys and moderate dilatation of the pelvicaliceal system bilaterally. A well-defined, echogenic, oval, mobile mass measuring 2.5 x 2.0 cm, without posterior acoustic shadowing, was visualized in the pelvis of the left kidney. The upper and middle ureters were dilated bilaterally. A urine culture revealed hyphae of candida albicans. The child received systemic antifungal therapy with fluconazole for 3 weeks. Follow-up sonography showed complete resolution of the mass (a fungal ball) with residual hydronephrosis.- - - - - - - - - - ranking = 1keywords = chill (Clic here for more details about this article) |
4/7. tongue discoloration in an elderly kidney transplant recipient: Treatment-related adverse event?BACKGROUND: With the increased occurrence of methicillin-resistant staphylococcus aureus infections, linezolid treatment might be administered more often. New rare adverse events are likely to follow. CASE SUMMARY: A 65-year-old man (weight, 91 kg; height, 185 cm) presented to the emergency department at the University of virginia-affiliated Salem veterans Affairs Medical Center, Salem, virginia, after a recent (8 weeks) kidney transplantation with a 24-hour history of fatigue, chills, arthralgias, increased urinary frequency, and onset of tongue discoloration. Two days before admission, he completed a 14-day course of linezolid 600 mg PO BID for ampicillin-resistant enterococcal urinary tract infection. He was afebrile on admission and the dorsal aspect of his tongue was blackened centrally, browner peripherally, with normal pink mucosa on the periphery. Based on the Naranjo probability scale, the calculated score for tongue discoloration as a drug-related adverse event was 7 out of a maximum score of 13 points, designating it as a probable cause. The patient's tongue discoloration improved moderately during the hospital stay and resolved 6 months after the discontinuation of linezolid. CONCLUSIONS: We report a rare association of linezolid and tongue discoloration in an elderly kidney transplant recipient that improved with discontinuation. We present this case to increase clinicians' awareness of the potential adverse event.- - - - - - - - - - ranking = 1keywords = chill (Clic here for more details about this article) |
5/7. fever and chills caused by nitrofurantoin taken after sexual intercourse.nitrofurantoin is one of many antibiotics used in the treatment of urinary tract infections (UTI). The drug is also used for the prevention of recurrent UTI in women. We report a case of nitrofurantoin drug fever associated with its use, following sexual intercourse, for chemoprophylaxis of UTI. The intermittent appearance of the side effects due to the occasional use of antibiotics, such as in this case, may easily lead to misdiagnosis.- - - - - - - - - - ranking = 4keywords = chill (Clic here for more details about this article) |
6/7. Histopathology and immunohistologic demonstration of the distribution of rickettsia typhi in fatal murine typhus.An 81-year-old woman had chills, fever, nausea, vomiting, and epigastric pain. On day 3 she had hematuria and was treated with trimethoprim-sulfamethoxazole. On day 5 she had a cough, hypotension, anemia, azotemia, and elevated hepatic enzyme levels. Her condition deteriorated with thrombocytopenia, anuria requiring dialysis, edema, and hypoalbuminemia. Treatment with chloramphenicol and doxycycline was started on day 10. By day 11, she was in hypotensive shock; on day 12 she had seizures and died. Murine typhus was diagnosed by demonstration of antibodies to rickettsia typhi by indirect immunofluorescence. Necropsy revealed interstitial pneumonia, pulmonary edema, hyaline membranes, alveolar hemorrhages, petechiae and vasculitis in the central nervous system, interstitial myocarditis, multifocal interstitial nephritis and hemorrhages, splenomegaly, portal triaditis, and mucosal hemorrhages in urinary tract. Immunofluorescent R. typhi were demonstrated in the lungs, brain, kidneys, liver, and heart. This unusual death occurred in an elderly patient without rash who was treated too late with antirickettsial drugs.- - - - - - - - - - ranking = 1keywords = chill (Clic here for more details about this article) |
7/7. Acute gram-negative urosepsis mimicking an acute hemolytic transfusion reaction.BACKGROUND: The acute hemolytic transfusion reaction (AHTR) is one of the most feared complications of blood transfusion. Over the years, several clinical conditions, as well as errors in blood component preparation and administration, that mimic AHTR have been identified. This report describes a novel variation on the theme of pseudo-AHTR. CASE REPORT: A 47-year-old diabetic man with drug-induced pancytopenia suddenly manifested severe shaking chills, flank pain, and back pain during a red cell transfusion. The passage of bright red urine immediately after the transfusion virtually confirmed for the clinicians administering the transfusion that an AHTR had occurred. In the laboratory, the hematuria was shown to be due principally to red cells and not to free hemoglobin. Further posttransfusion work-up showed a urinary tract infection and overwhelming bacterial sepsis with escherichia coli. CONCLUSION: As a pseudo-AHTR, gram-negative bacterial sepsis of urinary tract origin may surpass other forms of sepsis. Urosepsis should be considered in the work-up of a suspected AHTR in a pancytopenic patient with a urinary tract infection.- - - - - - - - - - ranking = 1keywords = chill (Clic here for more details about this article) |
