A rare case of a maxillo-mandibular band in a 21 year female patient is reported. Possibility of its being a remnant of buccaphary geal membrane is discussed in the light of clinical and histological findings. 相似文献
The serum apolipoprotein A (Apo A) and alpha-fetoprotein (AFP) were evaluated in histologically verified 30 cases of alcoholic cirrhosis and 18 cases of hepatocellular carcinoma (HCC). The latter were also divided into subgroups depending on the presence or absence of associated cirrhosis. Serum Apo A levels were found to be significantly decreased in cirrhotics (p less than 0.001) compared to controls and non-cirrhotic HCC patients. In 22 cases of alcoholic cirrhosis (AFP less than 10 ng/ml) and 12 cases of HCC (AFP greater than 600 ng/ml), the AFP levels itself were diagnostic, but in the remaining cases, AFP levels (100-600 ng/ml) were not able to differentiate between cirrhosis and malignancy. In this later group of patients with low pathological range of AFP, serum Apo A levels found to be significantly decreased in alcoholic cirrhotic patients (p less than 0.001) compared to HCC patients. Thus, estimation of Apo A levels may be helpful to interpret the AFP values at lower pathological range due to suspected liver pathology. 相似文献
Lobster-Claw syndrome is a rare autosomal dominant, hand-foot malformation with Oro-dental features. This is a rare condition and from the available reports so far, cases being reported are less than 1%. Most reports have focused on the hand-foot deformity of this syndrome. This paper highlights the typical Oro-dental features associated with this syndrome such as retained deciduous teeth, hypodontia and variation in crown size, arch length and arch width. 相似文献
Fiduxosin is a new alpha(1)-adrenoceptor antagonist targeted for the treatment of symptomatic benign prostatic hyperplasia. The purpose of this study was to determine and compare the potencies of the alpha(1)-adrenoceptor antagonists terazosin, doxazosin, tamsulosin, and fiduxosin, based on relationships between plasma drug concentrations and blockade of phenylephrine (PE)-induced intraurethral (IUP) and mean arterial pressure (MAP) responses after single oral dosing in conscious male beagle dogs. Magnitude of blockade and plasma concentrations were evaluated at selected time points over 24 h. All drugs produced dose-dependent antagonism of PE-induced IUP and MAP responses. When IUP and MAP blockade effects were plotted against drug plasma concentrations, direct relationships were observed that were well described by the sigmoidal maximal effect model. IUP IC(50) values for terazosin, doxazosin, tamsulosin, and fiduxosin were 48.6, 48.7, 0.42, and 261 ng/ml, respectively. MAP IC(50) values were 12.2, 13.8, 1.07, and 1904 ng/ml, respectively. Uroselectivity index values, defined as MAP IC(50)/IUP IC(50), were 0.25, 0.28, 2.6, and 7.3, respectively. These results extend previous observations with terazosin in this model, showing that doxazosin exhibits a uroselectivity index comparable to terazosin, consistent with the lack of alpha(1)-adrenoceptor subtype selectivity or uroselectivity of these drugs. Tamsulosin, an alpha(1a)-/alpha(1d)-subtype selective agent, had an index value approximately 10-fold greater than the nonselective drugs. Based on its pharmacokinetic profile and a relative uroselectivity 29-fold greater than the nonselective drugs, fiduxosin is expected to exhibit greater selectivity for urethral compared with vascular alpha(1)-adrenoceptors in human and should be a novel, long-acting, uroselective alpha(1)-adrenoceptor antagonist. 相似文献
Background: Voiding before discharge is usually required after outpatient epidural or spinal anesthesia because of concern about bladder overdistention and dysfunction. Shorter duration spinal and epidural anesthesia may allow return of bladder function before overdistention occurs in low-risk patients (those younger than age 70, not having hernia, rectal, or urologic surgery, and without a history of voiding difficulty), and predischarge voiding may not be necessary.
Methods: After institutional review board approval and informed consent, 201 low-risk ambulatory patients were prospectively studied in either a standard or accelerated pathway after undergoing spinal or epidural anesthesia with procaine, lidocaine, 2-chloroprocaine, or less than 7 mg bupivacaine; epinephrine was not used in any anesthetic. Standard pathway patients (n = 70) were required to void before discharge. Accelerated pathway (n = 131) patients were not required to void. (After randomization of an initial 163 patients to one of the two tracks, 38 additional patients were assigned to the accelerated pathway.) If accelerated pathway patients voided, they were discharged when all other discharge criteria were met. If they did not spontaneously void after block resolution, a bladder ultrasound (BUS) was performed. If the BUS indicated a urine volume of less than 400 ml, the patients were discharged and instructed to return to the emergency department if they were unable to void within 8 h of discharge. If the BUS indicated a urine volume of greater than 400 ml, the patients were reassessed in 1 h and were discharged if they could void spontaneously. If they could not void spontaneously, they were catheterized to facilitate discharge. All patients were contacted the next day to assess the return of normal bladder function.
Results: All standard pathway patients voided without difficulty, and were discharged in 153 +/- 49 (SD) min. 62 patients in the accelerated pathway voided spontaneously after resolution of their block and were discharged in 127 +/- 41 min. 46 patients were discharged with a BUS less than 400 ml in 120 +/- 42 min. 23 patients had a BUS greater than 400 ml: of these, 20 patients voided within an hour and were discharged in 162 +/- 45 min. Three were catheterized after 1 h, and were discharged in 186 +/- 61 min. Mean discharge time for all patients in the accelerated pathway was 22 min shorter than the standard pathway (P = 0.002). No patients had difficulty voiding or returned to the hospital for urinary problems. None reported new urologic symptoms. 相似文献
Pathological conditions are known to affect pharmacokinetics of many drugs. Antipyrine half-life is used as a marker of liver microsomal enzyme function. Antipyrine pharmacokinetics, therefore, was investigated in 23 thyrotoxic and 11 euthyroid goitre patients. Of these, 11 thyrotoxic and 9 euthyroid goitre patients also participated in doxycycline bioavailability studies. In thyrotoxic patients, antipyrine half-life and AUCo infinity and doxycycline Cpmax and AUCo infinity were found to be reduced as compared to those of healthy euthyroid normal subjects. Following treatment of thyrotoxicosis, the antipyrine half-life and AUCo infinity returned to normal. Doxycycline AUCo infinity returned to near normal range but Cpmax did not. 相似文献
