Pheochromocytoma (PCC) and paraganglioma (PGL) are uncommon tumors. Clinical manifestations are mass effect or hormone secretion. The initial manifestation with pericardial effusion is rare. The author presented a case of anterior mediastinum paraganglioma presenting with pericardial effusion two years before symptoms of catecholamine excess. This is the first case reported in Thailand. A 34 year-old female patient presented with dyspnea. There was pericardial effusion from echocardiography was diagnosed with no definite causes of pericardial effusion. After treatment with ibuprofen, pericardial effusion was absolutely resolved from repeated echocardiography. Two years later she had headache and hypertension. Chest X-ray, there was an anterior mediastinal mass. Her 24 hours urine metanephrine was very high. By imaging, an anterior mediastinal mass was observed from CT chest without adrenal mass from CT abdomen. The result of metaiodobenzylguanidine (MIBG) scan was compatible with paraganglioma. Symptoms of headache and hypertension disappeared after surgical removal of the mass. Pericardial effusion may be the first manifestation of paraganglioma especially if the patient had hypertension or could not find the etiology. Thus, pericardial effusion should be investigated for paraganglioma. Due to long term follow-up, this indolent growing tumor may respond to NSAIDs or regress spontaneously.

Ontogenic changes in choroidal vascular prostaglandin E2 (PGE2) receptors (EP1, EP2, EP3, and EP4), changes in receptor-coupled functions, and the possible role of high perinatal prostaglandin levels in regulating expression and function of these receptors were studied. PGE2 receptors and their functions on choroidal tissues were characterized by radioligand binding; by measurements of second messengers to receptor stimulation; and by vasomotor response to EP1, EP2, EP3, and EP4 ligands on perfused choroidal vascular beds from saline- and ibuprofen-treated (40 mg/kg every 4 every 4 hours for 48 hours) newborn pigs and from adult animals. PGE2 as well as EP2- and EP4-attributed choroidal stimulation elicited greater vasorelaxation in the saline-treated newborn and was associated with higher nitrite (oxidation product of NO, N omega-nitro-L-arginine inhibitable) production than in adult tissues. In contrast, EP1 and EP3 stimulation caused significantly more constriction in the adult than in the newborn, and this was associated with increased production of inositol 1,4,5-trisphosphate (IP3) and greater reduction of cAMP synthesis in the adult. Maximum [3H]PGE2 binding was also higher (3-fold) in adult than in newborn tissues. Competition binding studies revealed that of the PGE2 receptors in the adult choroid, approximately 55% were of the EP1 subtype, 8% were EP2, 22% were EP3, and 15% were EP4. Newborn choroid contained approximately 33% each of EP1 and EP2 receptors, 20% of EP3, and 15% of EP4. Inhibition of endogenous prostaglandin synthesis for 48 hours with ibuprofen in newborns to attain levels found in the adult resulted in an upregulation of [3H]PGE2 binding, EP1- and EP3-mediated vasoconstriction, and increases and decreases in IP3 and cAMP production, respectively, in newborn tissues compared with adult tissues. On the other hand, ibuprofen treatment of newborns led to a decrease in PGE2- and EP4-mediated vasorelaxation and nitrite synthesis (associated with decreased expression of endothelial NO synthase) to levels observed in adults: EP2-elicited responses in newborns were not affected by ibuprofen. In conclusion, fewer EP1 receptors (associated with vasoconstriction), more EP2 receptors, and greater EP4-coupled NO production (coupled to vasorelaxation) seem to be responsible for the increased vasodilation to PGE2 in the newborn. The decrease in prostaglandin levels with age appears to cause, on one hand, upregulation of EP1 and EP3 receptors and receptor-coupled vasoconstriction and, on the other hand, decreased EP4-coupled NO synthesis and choroidal vasodilation. Altogether, these factors result in increased vasorelaxation to PGE2 in the newborn compared with the adult. These findings may help to explain the inability of the newborn to autoregulate choroidal blood flow.

A novel empirical analytical approach for estimating solubility of crystalline drugs in polymers has been developed. The approach utilizes a combination of differential scanning calorimetry measurements and a reliable mathematical algorithm to construct complete solubility curve of a drug in polymer. Compared with existing methods, this novel approach reduces the required experimentation time and amount of material by approximately 80%. The predictive power and relevance of such solubility curves in development of amorphous solid dispersion (ASD) formulations are shown by applications to a number of hot-melt extrudate formulations of ibuprofen and naproxen in Soluplus. On the basis of the temperature-drug load diagrams using the solubility curves and the glass transition temperatures, physical stability of the extrudate formulations was predicted and checked by placing the formulations on real-time stability studies. An analysis of the stability samples with microscopy, thermal, and imaging techniques confirmed the predicted physical stability of the formulations. In conclusion, this study presents a fast and reliable approach for estimating solubility of crystalline drugs in polymer matrixes. This powerful approach can be applied by formulation scientists as an early and convenient tool in designing ASD formulations for maximum drug load and physical stability.

The prediction error of ≤50 % for mean clearance, volume of distribution, and half-life values were 69, 79, and 58 %, respectively, by proposed allometric models. The prediction error of ≤50 % for mean clearance, volume of distribution, and half-life values by theoretical allometric exponents were 0 % (exponent = 0.75), 71 % (exponent = 1.0), and 0 % (exponent = 0.25), respectively. In this analysis, out of 16 drugs, there were three drugs (ibuprofen, zidovudine, and buprenorphine) which are metabolized by glucuronidation and one drug (furosemide) is renally secreted. The predicted clearances of these four drugs were substantially higher by the proposed allometric methods. It seems that drugs of these physiological characteristics may require different method(s) to improve the prediction of clearance in the neonates.

Influence of tableting conditions on sticking was investigated using two formulations, the one formulation containing ibuprofen (formulation A) and the other being the standard formulation (formulation B). Sticking was observed on formulation A, and was not observed on formulation B. The degree of sticking was decreased with increase in compression pressure, and increased with compression speed. The shape of punch face was influenced the degree of sticking (sugar concave < bebel < flat). It was thought that sticking was observed when the adhesion between tablet and punch was larger than that among tableting granules. We investigated the pressure placed on a scraper (SCR), the adhesion between granules and metal, and boring hardness of tablet. The results showed that sticking was not observed when the SCR and/or the adhesion were small enough or boring hardness of tablet was high enough. Furthermore, it was suggested that boring hardness distribution would influence sticking.
Cultured rat fetal distal lung epithelial cells (FDLEs), when switched from fetal (3%) to postnatal (21%) O2 concentrations, have increased epithelial Na+ channel (ENaC) mRNA levels and amiloride-sensitive Na+ transport [O. Pitkänen, A. K. Tanswell, G. Downey, and H. O'Brodovich. Am. J. Physiol. 270 (Lung Cell. Mol. Physiol. 14): L1060-L1066, 1996]. The mechanisms by which O2 mediates these effects are unknown. After isolation, FDLEs were kept at 3% O2 overnight, then switched to 21% O2 (3-21% O2 group) or maintained at 3% O2 (3-3% O2 group) for 48 h. The amiloride-sensitive short-circuit current (Isc) in the 3-21% O2 group was double that in the 3-3% O2 group. Amiloride-sensitive Isc could not be induced by medium conditioned by 21% O2-exposed FDLEs but was reversed by returning the cells to 3% O2. Neither the cyclooxygenase inhibitor ibuprofen, liposome-encapsulated catalase, nor hydroperoxide scavengers (U-74389G or Trolox) blocked the O2-induced amiloride-sensitive Isc. In contrast, the cell-permeable superoxide scavenger tetramethylpiperidine-N-oxyl (TEMPO) eliminated the O2-induced increases in amiloride-sensitive Isc and ENaC mRNA levels. The switch from 3 to 21% O2 induced the transcription factor nuclear factor-kappaB, which could also be blocked by TEMPO. We conclude that 1) the O2-induced increase in amiloride-sensitive Isc is reversible and 2) the O2-induced increase in amiloride-sensitive Isc and ENaC mRNA levels is associated with activation of nuclear factor-kappaB and may be mediated, at least in part, by superoxide.

Older adults commonly take nonsteroidal anti-inflammatory drugs (NSAIDs) chronically. Studies of older adults show that chronic NSAID use increases the risk of peptic ulcer disease, acute renal failure, and stroke/myocardial infarction. Moreover, chronic NSAID use can exacerbate a number of chronic diseases including heart failure and hypertension, and can interact with a number of drugs (eg, warfarin, corticosteroids). Preferred analgesics in older adults that may have a lower risk of these adverse drug reactions include acetaminophen, a nonacetylated salicylate (eg, salsalate), a short half-life NSAID (eg, ibuprofen), or low-dose opioid/opioid-like agents in combination with acetaminophen (in appropriate patients).

We conclude that pain therapy with an almost peripherally acting drug such as ibuprofen can reduce osteoporosis-associated chronic pain better than a centrally acting pain medication such as tramadol. It therefore can be recommended to prescribe ibuprofen rather than tramadol for treating osteoporosis-associated chronic pain in postmenopausal women if the specific risk for gastrointestinal side effects is considered.
At 24 to 48 hours after birth, plasma superoxide dismutase (SOD), urinary catalase, and plasma and urinary 8-isoPGF2α were significantly lower in preterm infants who developed hsPDA. Plasma 8-isoPGF2α levels rebounded post-PDA treatment, while urinary prostaglandin E2, plasma and urinary thromboxane B2, and plasma SOD declined.

Ketoprofen at doses of 25 mg to 100 mg is an effective analgesic in moderate to severe acute postoperative pain with an NNT for at least 50% pain relief of 3.3 with a 50 mg dose. This is similar to that of commonly used NSAIDs such as ibuprofen (NNT 2.5 for 400 mg dose) and diclofenac (NNT 2.7 at 50 mg dose). Duration of action is about 5 hours. Dexketoprofen is also effective with NNTs of 3.2 to 3.6 in the dose range 10 mg to 25 mg. Both drugs were well tolerated in single doses.
Ibuprofen was milled in the solid state with kaolin (hydrated aluminium silicate) in different ratio to examine the extent of transformation from crystalline to amorphous state. The physical stability of the resultant drug was also investigated. X-ray powder diffractometry (XRD) and birefringence by Scanning Electron Microscopy (SEM) studies indicated almost complete amorphization of the drug on ball milling with kaolin at 1:2 ratio. Fourier transform infrared spectroscopy (FTIR) data showed a reduction in the absorbance of the free and the hydrogen-bonded acid carbonyl peak of carboxylic acid group accompanied by a corresponding increase in the absorbance of the carboxylate peak, indicating an acid-base reaction between the carboxylic acid containing ibuprofen and kaolin on milling. The extent of amorphization and reduction in the carbonyl peak and increase in carboxylate peak was a function of kaolin concentration in the milled powder. On storage of milled powder (at 40 degrees C and 75% RH for 10 weeks), XRD and birefringence of SEM study showed the absence of reversion to the crystalline state and FTIR data revealed continued reduction of carbonyl peak, whereas, ibuprofen converted from its crystalline acid form to amorphous salt form on milling with kaolin. Kaolin-bound state of ibuprofen was physically stable during storage. In-vitro dissolution studies revealed that percent release of ibuprofen from the kaolin co-milled powder is in the order: 1:2>1:1>1:0.5>1:0.1>milled alone ibuprofen>crystalline ibuprofen.

Analgesics are still the main treatment modality to reduce orthodontic pain despite their side effects. Some long-acting nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclo-oxygenase enzyme (COX-2) inhibitors are recommended for their comparatively lesser side effects. Their preemptive use is promising. Other approaches such as LLLT have aroused researchers' attention.
Linear eruptions are sometimes associated with systemic diseases and they may also be induced by various drugs. Paradoxically, such acquired inflammatory skin diseases tend to follow the system of Blaschko's lines. We describe a case of unilateral linear drug eruption caused by ibuprofen, which later became bilateral and generalized.
Many pharmaceuticals and personal care products (PPCPs) have been shown to be biotransformed in water treatment systems. However, little research exists on the effect of initial PPCP concentration on PPCP biotransformation or on the microbial communities treating impacted water. In this study, biological PPCP removal at various concentrations was assessed using laboratory columns inoculated with wastewater treatment plant effluent. Pyrosequencing was used to examine microbial communities in the columns and in soil from a soil aquifer treatment (SAT; a method of water treatment prior to reuse) site. Laboratory columns were supplied with different concentrations (0.25, 10, 100, or 1,000 μg liter(-1)) of each of 15 PPCPs. Five PPCPs (4-isopropyl-3-methylphenol [biosol], p-chloro-m-xylenol, gemfibrozil, ketoprofen, and phenytoin) were not removed at any tested concentrations. Two PPCPs (naproxen and triclosan) exhibited removals independent of PPCP concentration. PPCP removal efficiencies were dependent on initial concentrations for biphenylol, p-chloro-m-cresol, chlorophene, diclofenac, 5-fluorouracil, ibuprofen, and valproic acid, showing that PPCP concentration can affect biotransformation. Biofilms from sand samples collected from the 0.25- and 10-μg liter(-1) PPCP columns were pyrosequenced along with SAT soil samples collected on three consecutive days of a wetting and drying cycle to enable comparison of these two communities exposed to PPCPs. SAT communities were similar to column communities in taxonomy and phylotype composition, and both were found to contain close relatives of known PPCP degraders. The efficiency of biological removal of PPCPs was found to be dependent on the concentration at which the contamination occurs for some, but not all, PPCPs.
