Homeostasis of ionized calcium in biofluids is critical for human biological functions and organ systems. Measurement of ionized calcium for clinical applications is not easily accessible due to its strict procedures and dependence on pH. pH balance in body fluids greatly affects metabolic reactions and biological transport systems. Here, we demonstrate a wearable electrochemical device for continuous monitoring of ionized calcium and pH of body fluids using a disposable and flexible array of Ca(2+) and pH sensors that interfaces with a flexible printed circuit board...

Carbonic anhydrases are a group of isoenzymes that catalyze the reversible conversion of carbon dioxide into bicarbonate. They participate in a constellation of physiological processes in humans, including respiration, bone metabolism, and the formation of body fluids, including urine, bile, pancreatic juice, gastric secretion, saliva, aqueous humor, cerebrospinal fluid, and sweat. In addition, carbonic anhydrase may provide carbon dioxide/bicarbonate to carboxylation reactions that incorporate carbon dioxide to substrates...

New methods for quantitative analysis of strong anions are required for diagnostic testing of human diseases. Current techniques suffer from poor selectivity and/or long analysis times that are not amenable for labile anions in high-saline or volume-restricted samples. We introduce a rapid assay (<5 min) based on capillary electrophoresis (CE) with indirect UV detection for simultaneous analysis of sulfate, sulfite, and chloride in human urine, plasma, and sweat specimens. Remarkable selectivity for strong anions is achieved by using an acidic background electrolyte under reversed polarity that results in electrokinetic rejection of matrix interferences at the capillary inlet...

We report two rare examples of Epstein-Barr virus (EBV)-associated inflammatory pseudotumor of the spleen. One patient presented with night sweats, abdominal pain, and weight loss and was found to have a splenic mass on CT scan suspected of lymphoma. The splenic mass in second patient was found incidentally at the time of work up for kidney stones. The pathologic examination of these splenectomy specimens showed similar histologic features. However, the spindle cells were composed of EBV-infected follicular dendritic cells in one case whereas the second case lacked significant follicular dendritic cell proliferation and showed only focal EBV-infected cells suggesting that these proliferations are heterogenous in nature...

Splenic lymphoma, or primary malignant lymphoma of the spleen (PMLS), is an uncommon condition whose true nature is difficult to define due to the variable ways it has been classified. Out of all non-Hodgkin's lymphomas it comprises less than 2% of cases. Some experts suggest that PMLS only involves the spleen and splenic hilum, while others consider PMLS to be an entity that develops within the spleen and later has the potential for invading adjacent organs and metastasizing. Clinical features of splenic lymphoma are characterized by nonspecific systemic symptoms such as low grade fevers, night sweats and symptoms related to considerable splenomegaly...

Previous studies of renal stone disease (RSD) in Thailand indicated abnormal urinary aggregator and inhibitor composition among farmers with excessive sweat loss. Our aim was to compare the proton MR spectra obtained from the kidneys of 32 proven cases of RSD (aged 38 to 65 yrs) with nine age-matched normal control subjects. We used the STEAM sequence with TE = 15 ms and TR = 2,000 ms. The spectra at 3.25, 3.6 and 3.9 ppm were analyzed. The results showed a correlation between the three peaks (p < 0.001), however, there was no significant difference between the RSD group and the normal control subjects...

The uses, pharmacology, clinical efficacy, dosage and administration, adverse effects, and drug interactions of hawthorn are discussed. Hawthorn (Crataegus oxyacantha) is a fruit-bearing shrub with a long history as a medicinal substance. Uses have included the treatment of digestive ailments, dyspnea, kidney stones, and cardiovascular disorders. Today, hawthorn is used primarily for various cardiovascular conditions. The cardiovascular effects are believed to be the result of positive inotropic activity, ability to increase the integrity of the blood vessel wall and improve coronary blood flow, and positive effects on oxygen utilization...

STUDY DESIGN: A study of four patients with spinal cord injury (SCI) in whom a diagnosis of hydronephrosis or pyonephrosis was delayed since these patients did not manifest the traditional signs and symptoms. OBJECTIVES: To learn from these cases as to what steps should be taken to prevent any delay in the diagnosis and treatment of hydronephrosis/pyonephrosis in SCI patients. SETTING: Regional Spinal Injuries Centre, Southport, UK. METHODS: A retrospective review of cases of hydronephrosis or pyonephrosis due to renal/ ureteric calculus in SCI patients between 1994 and 1999, in whom there was a delay in diagnosis...

Sixteen villages from rural areas of 8 provinces in the northeastern region of Thailand were randomly selected as study sites. Data on potassium (K) contents in 24-hour urine and serum samples of 93 healthy adult volunteer males aged 20-50 years old were completely collected and covered all 3 seasons of the year. The method of direct weighing of food was used to assess K intake in 13 subjects. K loss through sweat during working (9 hours) in the field was measured in 14 subjects by soaking their worn-clothes in distilled water after which K contents were measured by the flame photometry method...

We investigated the prevalence of stone disease and urinary stone risk factors in machinists chronically exposed to a hot environment and massive sweating, without interference of nephrotoxic metals or other lithogenic compounds. The study was performed at a glass plant and exposure to heat stress was estimated by the Wet Bulb Globe Temperature climatic index. The prevalence of nephrolithiasis on the entire population of the machinists was 8.5% (20 of 236), while the prevalence on the controls working in normal temperature was 2...

Of 893 stone procedures 37 (4.1 per cent) performed during the first 19 months after extracorporeal shock wave lithotripsy was instituted at our medical center were open operations. Procedures included ureterolithotomy in 23 patients (with simultaneous pyelolithotomy in 1), anatrophic nephrolithotomy in 8, pyelolithotomy in 3 (with concomitant pyeloplasty in 2), partial nephrectomy in 2 and nephrolithotomy with a bowel segment inlay in 1. The most common reasons for electing an open operation were unsuccessful endoscopic stone manipulation, presence of anatomical obstruction in the intrarenal collecting system or ureter, morbid obesity and underlying medical problems precluding lengthy repeated endourological procedures...

Twenty-four patients undergoing extracorporeal piezolithotripsy took part in this study and underwent treatment on a Wolf Piezolith 2300 Lithotripter, which does not require any type of anaesthesia and enables the patient to be treated as an out-patient. Previous work has investigated anxiety states of patients during investigative procedures and found that information given prior to the procedure is beneficial in reducing the levels of anxiety reported. Modern urological surgery carried out to remove kidney stones has progressed to non-invasive techniques with the introduction of extracorporeal piezolithotripsy (EPL)...
