Pregnancy can be complicated with different surgical emergencies which may potentially endanger the mother as well as foetus. In the modern era of advanced diagnostics and treatments, neither of them in response to a surgical emergency in a pregnant woman should be delayed. Appropriate early intervention is essential to decrease the morbidity and mortality. Following article encompasses common surgical emergencies that can arise in a pregnant woman and tries to suggest the approach that may be taken to reduce the burden of morbidity and mortality. 相似文献
1. The present study is designed to investigate the brain distribution and plasma pharmacokinetics profiles of chlorogenic acid (CGA) after intranasal administration in Charles–Foster rats to evaluate whether the CGA molecules are transported directly via the nose-to-brain path.
2. The CGA is administered intravenously (IV) and intranasally (IN) at the dose of 10?mg/kg. Further, its concentration in the plasma, cerebrospinal fluid (CSF) and the whole brain is analyzed by HPLC-UV method.
3. The study observes that CGA is rapidly absorbed in plasma with tmax of 1?min similar to IV route after IN administration. The peak plasma concentration and AUC0–24 are higher by 3.5 and 4.0 times respectively in IV administration, compared to IN delivery that represents the significant less systemic exposure of CGA in IN route.
4. However, the concentration of CGA in the brain is 4, 6.5, 5.3, 5.2 and 4.5 times higher at 30, 60, 120, 240 and 360?min, respectively in IN administration compared to IV administration. The exposure of CGA in the brain after IN administration (AUCbrain, IN) was significantly greater (4 times) as compared to the exposure of CGA in the brain (AUCbrain, IV) after IV administration reflecting significant brain uptake of CGA through nasal route. Therefore, IN delivery of CGA can be a promising approach for the treatment of stroke and neurodegenerative disorders. 相似文献
Studies on the development of imaging agents for targeting neuroreceptors is an area of considerable interest owing to the limited availability of specific as well as selective radiolabeled agents. Therefore, with an aim of developing a receptor-specific agent, iminodiacetic acid (IDA) derivative of 5-hydroxy tryptamine viz., HTIDA has been synthesized. HTIDA could be radiolabeled with the synthon [(99m)Tc(CO)(3)(H(2)O)(3)](+) in >98% yield. The biodistribution studies in normal Swiss mice showed that the (99m)Tc(CO)(3)-HTIDA crosses the blood-brain barrier successfully with a brain uptake of 0.5%ID/g at 5min post injection. The other relevant observations from biodistribution studies included no significant uptake in any other organ and fast clearance from blood, lungs and liver. 相似文献
Awareness among the general population of the risk factors and warning symptoms of stroke is essential for preventative purposes and for immediate effective treatment. The aim of the present study was to assess the awareness, among the general population and stroke survivors, of the risk factors and warning symptoms of stroke, to develop an educational strategy for its prevention and immediate effective treatment. Six hundred and sixty stroke patients (370 male, 290 female) and 4000 people from the general population who accompanied the patients (2800 male, 1200 female) were interviewed, using three sets of questionnaires, on the risk factors and warning symptoms of stroke. Poor knowledge or awareness of the risk factors and warning symptoms of stroke was found in both groups. Both groups suggested educational programs for stroke using printed information, audiovisual programs and community survey programs using simple and understandable information for the prevention and immediate effective treatment of stroke. Poor awareness of stroke contributes to a delay in the arrival of patients in hospital emergency departments for immediate effective treatment. Multifaceted programs regarding stroke, including printed information, audiovisual programs and stroke service programs, are advocated by both patients and the general population to improve stoke treatment and prevention. 相似文献
Introduction Hydatid cysts of the lung are quite frequent in our country. Some patients have additional cysts in the liver. Though most
of the liver cysts remain asymptomatic for long time, but may be symptomatic with increasing size. Surgical removal is the
treatment of choice for both lung & liver cysts. Aim of the study was to establish suitability of one stage surgery for pulmonary
& hepatic hydatid cysts.
Methods From 1996 through 2003 we operated on 216 pulmonary hydatid cysts, out of which 42 patients had hydatid cysts in the right
lung as well as in the right lobe of liver. Right thoracotomy was done to remove the lung hydatids followed by phrenotomy
to remove the liver cysts.
Results Right thoracotomy was done in 42 patients having hydatid cysts of lung & liver. In 36 patients, cysts were removed, bronchial
leaks were sutured & residual cavities were obliterated. Out of rest 6 patients, having dense adhesions or destruction of
pulmonary parenchyma, 4 had segmentectomy & 2 had lobectomy. Right phrenotomy was then done with radial incision above the
palpated liver cysts. Hydatid cyst was removed from liver. Cavity and remaining pericystic liver tissue was inverted with
sutures. Water seal chest drain & subdiaphragmatic drain were placed. Post operative albendazole was continued for 3 months
in the dose of 10–20 mg/kg with a gap of 2 weeks after each month. Post operative recovery was uneventful in most of the cases.
However, air leak continued for almost 3 weeks in 4 patients & 3 months in one patient. There was no death.
Conclusion Surgical management of pulmonary and hepatic hydatids with one stage right thoracotomy & phrenotomy is a suitable option.
It avoids additional laparotomy and thereby additional cost & hospital stay. Results are quite satisfactory. 相似文献
Fourteen patients of non-cirrhotic portal fibrosis (NCPF) with portal hypertension were put on oral diltiazem hydrochloride (90 mg/day) or placebo on a prospective, randomised, single blind basis for 15 days. Predrug hemodynamic and biochemical status were similar in both groups. Diltiazem produced significant reduction (p less than 0.001) in mean intrasplenic pressure: from 41.88 (SD +/- 6.18) to 21.5 (+/- 7.91) cm of normal saline as against 45.56 (+/- 9.45) to 43.33 (+/- 8.27) in the placebo group. Mean arterial pressure (MAP), heart rate and cardiac output (CO) did not change in either group. Thus, the calcium channel blocker diltiazem reduces portal pressure in patients with NCPF, independent of reduction in MAP and CO; this is advantageous in situations where compromised cardiac hemodynamics may prove deleterious. 相似文献
