A 10-year-old Japanese girl developed acute renal failure following a 100-meter dash during physical training at school. After the run, she experienced intense pain in the loins with nausea and vomiting lasting more than 12 h. On the following morning, she was found to have mild proteinuria and acute renal failure (ARF). Serum creatinine and blood urea nitrogen were elevated, but the serum uric acid level was normal (3.1 mg/dL). With recovery of renal function over the ensuing days, hypouricemia (0.6 mg/dL) became evident in the patient. Although the pathophysiological association between renal hypouricemia and ARF is not known, oxygen free radicals have been implicated in the pathogenesis for ischemic-reperfusion ARF. Superoxide production by neutrophils stimulated by N-formyl methionine leucyl-phenylalanine was normal in the patient both before and following exercise. Pyrazinamide and probenecid tests were undertaken on both the patient and her parents, who had borderline hypouricemia, to determine their renal tubular handling of uric acid. Results showed that the patient and her mother had a subtotal reabsorption defect, while the father had defective postsecretory uric acid reabsorption.

Bioanalytical methods for determining the total concentration of the new local anaesthetic drug ropivacaine in blood plasma, urine and tissues are presented. Ropivacaine is a drug mainly used in connection with surgery and for post-operative pain relief. The biological samples were prepared using liquid-liquid extraction and analysed using capillary gas chromatography with nitrogen-phosphorus detection or mass spectrometry. The methods are highly selective and reliable with a between-day precision, given as the relative standard deviation, generally below 6%. More than 20000 samples have been analysed using the methods described.

Therapeutic ethanol injection into primitive or secondary hepatic tumours if performed in "one shot" causes a great deal of pain. For this reason an analgesic/sedation protocol was devised. This relies on the administration of ketorolac-propofol-nitrogen oxide mixture that has been used to treat patients with neoplastic hepatic diseases. A 20 patient series is described. Analgesic protocol was very effective and the only drawbacks were a residual sleepiness than in part is probably dependent on ethanol emigration into the bloodstream and consequently to the central nervous system depression.

Seven new phthalimide derivatives (9a-g) with 1,2,4-oxadiazol-5-yl methyl group attached to nitrogen have been synthesized from N-phthaloylglycine 6 and arylamidoximes 7a-g. All of these showed potent analgesic effect with acetic acid induced "writhing" test in mice. One of the better compounds (ID50 = 2.2 mg/Kg i.p.) has been found to be 9a which also demonstrates analgesic activity against inflammatory pain.

Cryotherapy is use of temperature lower than -100 degrees C onto body surface, for 2-3 minutes, in aim to cause physiological reactions for cold and to use such adapting reactions. Organism's positive response to cryotherapy supports treatment of basic disease and facilitates kinesitherapy. Low temperature may be obtained by use of air flow cooled with liquid nitrogen; this could be applied either locally, over chosen part of the body, or generally, over the whole body, in cryosauna or in cryochamber. The most efficiently is applying cryotherapy twice a day, with at least 3 hours interval. Kinesitherapy is necessarily used after each cryotherapy session. Whole treatment takes 2 to 6 weeks, depending on patient's needs. Cryotherapy reduces pain and swellings, causes skeletal muscles relaxation and increase of their force, also, motion range in treated joints increases. Thus, cryotherapy seems to fulfill all necessary conditions for rehabilitation in osteoporosis. Cryotherapy represents numerous advantages: it takes short time for applying, being well tolerated by patient, also patient's status improves quickly. In addition, contraindications against cryotherapy are rare. All this makes cryotherapy a method for a broad use in prophylactics and treatment of osteoporosis.

Low-frequency fatigue was investigated in nine female and one male adult pigtail monkeys (Macaca nemestrina) with a mean weight of 5.3 kg (range 4.3 to 6.5 kg). After sedation and anesthesia, silver electrodes were inserted into the anterior and posterior parts of the right masseter muscle. The contralateral muscle was used as a control. The masseter muscles were stimulated for 3 minutes (4 Hz, 2 ms, 100 V). After a 5-minute rest period, the stimulation was repeated with the same duration and voltage but at a higher frequency of 8 Hz. Bite forces were measured, and muscle biopsies were obtained from the central part of the right masseter and immediately frozen in liquid nitrogen. After freeze-drying, a fluorometric analysis that used enzymatic methods for measuring levels of glycogen, glucose, lactate, pyruvate, creatine phosphate, nicotinamide-adenine dinucleotide (NAD), and reduced NAD (NADH) was performed. The bite force decreased by 12% after the initial 3 minutes of work. After the second contraction the bite force decreased to 56%. Prominent substrate depletion was observed. The precontraction levels of glycogen, glucose, and phosphocreatine were all reduced. The NADH and the NAD concentrations increased. An accumulation of metabolites was evident. The pyruvate increased by 32% and lactate levels increased by a factor of 3. The male measurements were comparable to the nine female measures for each assessment. The substantial substrate depletion in combination with a prominent accumulation of metabolites may contribute to the development of low-frequency fatigue.

We describe a case of a 15-year-old African American girl with widespread papulonodular lesions of xanthoma disseminatum especially in the periorbital area and on the flexural surfaces of the neck, axillae, arms, and legs. There were no mucosal lesions. An initial trial in the distant past of liquid nitrogen cryotherapy resulted in partial shrinking of cutaneous lesions but was too painful for the patient. She then underwent surgical excision of bilateral eyelid lesions with improvement, but additional procedures were deemed impractical when considering the great number and size of the lesions. Consequently we treated the patient with a carbon dioxide (CO2) laser with excellent results. The relatively great speed at which the CO2 laser procedure can be performed has made the removal of multiple lesions in each session possible. Additional advantages included precise vaporization of lesions, hemostasis during the operative procedure, and minimal postoperative pain and edema.

Vertebral physitis with bone sequestration and a portosystemic shunt were diagnosed in an 18-month-old female Pekingese dog. The latter was determined by the presence of low blood urea nitrogen, elevated serum bile acids, microhepatica and an increased portosystemic shunt fraction. It was managed with a home-cooked low protein diet. Vertebral physitis and bone sequestration was diagnosed by the presence of thoracolumbar hyperaesthesia, radiographic and scintigraphic changes, isolation of Staphylococcus intermedius from blood and the third lumbar vertebra, and histopathological examination of a surgical biopsy. A partial sequestrectomy was performed and a six-month course of amoxycillin-clavulanate was prescribed. The dog was pain-free and showed partial resolution of the radiographic signs four months after the discontinuation of antibiotics.

52 cases of postrenal acute renal failure (ARF) from 1985 to 1995 were studied. 50 cases underwent emergency operation, and 2 were drained with ureter intubation by cystoscope. 37 cases (71.2%) were cured, 14 (26.9%) were improved, and 1 (1.9%) died. Oliguria, anuria and progressive increase of blood urea nitrogen and serum creatinine are the main points of diagnosis. Renal percussive pain is the important sign. B-ultrasonography examination is the first choice and often indicate the increase of the volume of kidney and mild hydronephrosis. Obstruction should be removed as quickly as possible, infection should be prevented and treated to protect renal function. The way of treatment should be adopted according to the variant causes and conditions of disease. The etiology, clinical findings, diagnosis, operating methods and cautions were discussed.

The development of exceptionally potent inhibitors of fatty acid amide hydrolase (FAAH), the enzyme responsible for the degradation of oleamide (an endogenous sleep-inducing lipid), and anandamide (an endogenous ligand for cannabinoid receptors) is detailed. The inhibitors may serve as useful tools to clarify the role of endogenous oleamide and anandamide and may prove to be useful therapeutic agents for the treatment of sleep disorders or pain. The combination of several features-an optimal C12-C8 chain length, pi-unsaturation introduction at the corresponding arachidonoyl Delta(8,9)/Delta(11,12) and oleoyl Delta(9,10) location, and an alpha-keto N4 oxazolopyridine with incorporation of a second weakly basic nitrogen provided FAAH inhibitors with K(i)s that drop below 200 pM and are 10(2)-10(3) times more potent than the corresponding trifluoromethyl ketones.
