An unusual cause of allergy: Case report of normal saline solution allergy

Anaphylaxis and acute allergic reactions may sometimes be fatal. They occur within minutes in a sensitized individual. So quick diagnosis and management are necessary issues. In the literature, cases are widely reported against allergens found in drugs, foods and their additives, radiocontrast material, bee stings, and many other materials. Here, we present a 37-year-old woman who developed an anaphylactic reaction to normal saline infusion during evaluation for her acute abdominal pain. We found only one report about normal saline allergy in the literature (Litvin ME, Shemchuck AS, Lisetskii VA. Anaphylactic shock caused by intravenous injection of isotonic solution of sodium chloride. Klin Khir 1976;(7):59-61).     

Promoter hypermethylation of the <Emphasis Type="Italic">SFRP2</Emphasis> gene is a high-frequent alteration and tumor-specific epigenetic marker in human breast cancer

Background  

We have previously reported that expression of the Wnt antagonist genes SFRP1 and SFRP5 is frequently silenced by promoter hypermethylation in breast cancer. SFRP2 is a further Wnt inhibitor whose expression was recently found being downregulated in various malignancies. Here we investigated whether SFRP2 is also implicated in human breast cancer, and if so whether SFRP2 promoter methylation might serve as a potential tumor biomarker.     

Giant Cervical Polyp Due to a Foreign Body in a ''Virgin''

A 17-year-old virgin who had a giant cervical polyp which had developed through a foreign body and protruded out of the hymen was evaluated; the aetiological significance of the foreign body in the formation of the cervical polyp is discussed.     

Cutaneous anthrax of the hand and its reconstruction with a reverse-flow radial forearm flap

Bacillus anthracis infection can lead to necrosis in tissues and may manifest as a fatal disease in human beings. The authors present a patient with a large area of skin necrosis on the dorsum of the hand that was reconstructed with a reverse flow-through radial forearm flap, and they discuss the relevant literature. To the authors' knowledge, this is the first published report of such extensive necrosis resulting from anthrax limited to the extensor retinaculum of the hand.     

Simultaneous occurrence of papillary intrafollicular and microcarcinomas with bilateral medullary microcarcinoma of the thyroid in a patient with multiple endocrine neoplasia type 2A: report of a case

We report the case of a simultaneous occurrence of papillary intrafollicular and microcarcinomas with bilateral medullary microcarcinoma of the thyroid in a patient with multiple endocrine neoplasia type 2A. The concurrent presence of two thyroid carcinomas is rare. The simultaneous occurrence of two different tumors in the same thyroid each being multifocal and smaller than 1 cm in diameter has not been previously reported in the literature. Furthermore, we define the first case of intrafollicular papillary thyroid carcinoma (carcinoma in situ). Received: June 11, 2001 / Accepted: January 8, 2002     

Spironolactone: is it a novel drug for the prevention of amphotericin B-related hypokalemia in cancer patients?

OBJECTIVE: Nephrotoxicity is the major adverse effect of amphotericin B (AmB), often limiting administration of full dosage. Selective distal tubular epithelial toxicity seems to be responsible for the profound potassium wasting that is a major clinical side effect of treatment with AmB. Potassium depletion also potentiates the tubular toxicity of AmB. This study was designed to assess the ability of spironolactone to reduce potassium requirements and to prevent hypokalemia in neutropenic patients on AmB treatment. METHODS: In this study 26 patients with various hematological disorders were randomized to receive either intravenous AmB alone or AmB and oral spironolactone 100 mg twice daily when developing a proven or suspected fungal infection. RESULTS: Patients receiving concomitant AmB and spironolactone had significantly higher plasma potassium levels than those receiving AmB alone (P = 0.0027). Those patients receiving AmB and spironolactone required significantly less potassium supplementation to maintain their plasma potassium within the normal range (P = 0.022). Moreover, urinary potassium losses were significantly less in patients receiving AmB and spironolactone than those receiving AmB alone (P = 0.040). CONCLUSION: This study showed that spironolactone can reduce potassium requirements and prevent hypokalemia by reducing urinary potassium loss in neutropenic patients on AmB treatment.     

Effect of subminimal inhibitory concentrations of three fluoroquinolones on adherence of uropathogenic strains of Escherichia coli

The effect of subinhibitory concentrations (1/2-1/32 x MIC) of ciprofloxacin, ofloxacin and levofloxacin on the adherence of three strains of Escherichia coli (a mannose-resistant haemagglutinating clinical isolate, a non-haemagglutinating clinical isolate and the mannose-resistant haemagglutinating ATCC 25922 strain) were studied. Ciprofloxacin had the lowest MIC values but only the 1/2 MIC concentration inhibited adherence of mannose-resistant haemagglutinating strains after exposure to subMIC values. Significant inhibition of adherence was observed with 1/4 x MIC ofloxacin for both haemagglutinating isolate (27096) and the ATCC strain. Levofloxacin might be more effective and safer than ciprofloxacin and ofloxacin as a long acting fluoroquinolone at subMIC values in patients with UTI.
