Thoracic patients frequently have a painful wound after surgery. So analgesia after thoracic surgery is of particular significance. In the present study we assessed the efficacy of thoracic paravertebral and epidural blockade on post thoracotomy pain and pulmonary function. Thirty adult ASA I-III patients undergoing elective thoracic surgery were enrolled in this study. they were randomly divided into two groups : paravertebral and epidural group (15 patients each). Both percutaneous paravertebral and epidural catheters were placed preoperatively. Before chest closure each patient received a bolus dose of bupivacaine (0.25 %) according to its height. This was followed by postoperative bupivacaine infusion (0.25 %) 0.1 ml kg-1h –1 in both groups. Also patients were encouraged to take supplementary doses of morphine from a patient controlled analgesia (PCA). Subjective pain relief was assessed on a linear visual analogue scale and pulmonary function was measured by spirometry. Stress responses to noxious stimuli was assessed by plasma levels of cortisol and glucose. Respiratory variables were recorded throughout the study period. Also sensory level of analgesia and performance status were assessed in the two groups. Although we found significantly lower visual analogue pain scores at rest and on maximal coughing in the paravertebral compared to the epidural group, no significant difference in patient controlled morphine requirements was noted between the two groups. Pulmonary function (FVC, FEV1 and PEFR) was significantly better in the paravertebral group. Meanwhile no significant difference in respiratory variables was recorded between the two groups. Paravertebral block produced significantly diminished stress responses to noxious stimuli as manifested by less increase in plasma cortisol level than in epidural block. Sensory levels of analgesia and performance status was similar in both groups. Side effects as hypotension, urine retention, nausea and difficulty in breathing were troublesome in the epidural group. While nausea and difficulty in breathing were less in paravertebral group.

Consumption of NSAIDs has been associated with the infrequent occurrence of ulcers at other locations, such as the jejunum, ileum and colon. Several studies have suggested that consumption of NSAIDS also constitutes a risk factor for the development of erosive oesophagitis, including oesophageal strictures. It is now documented that NSAIDS are associated with gastro- oesophageal reflux disease (GERD). It was found recently that GERD is associated with a variety of laryngeal conditions and symptoms, of which “reflux laryngitis” is the most common. AIM OF THE WORK: is to study the effect of NSAIDs on the development of laryngitis in patients with GERD. PATIENTS AND METHODS: study included 60 patients, 42 males and 18 females aged between 26 – 52 years old (mean 37.9), a detailed history was taken from all patients. All the sixty patients were suspected to have GERD based on symptoms including acid reflux, Group I: - 40 patients were receiving daily-recommended doses of NSAIDs for at least one month for a diagnosed rheumatological disease, Group II: - 20 patients who were diagnosed as GERD, and were not receiving any NSAIDs for at least one month prior to the present study. The sixty patients were subjected to upper gastrointestinal endoscopy. Patients who were diagnosed as GERD with or without oesophagitis were subjected to ENT fibro-optic laryngoscopy. RESULTS: 42% of all patients with GERD have hoarseness of voice, 30% have recurrent chocking, 53% have excessive throat cleaning. Postglottic oedema, arytenoid oedema, vocal fold oedema, were all significantly higher in group I than in group II. CONCLUSION: The chronic use of NSAIDs can be considered as a risk factor for developing GERD, erosive oesophagitis with or without subsequent posterior laryngitis. Laryngoscopy may have a predictive value for the occurrence of GERD in those patients. Patients who were on regular use of NSAIDS, and are symptomatic for GERD are recommended to start medical treatment for GERD to guard against erosive oesophagitis and/or posterior laryngitis. }, keywords = {}, url = {https://ejhm.journals.ekb.eg/article_18895.html}, eprint = {https://ejhm.journals.ekb.eg/article_18895_4f077a57ce2f25116e8fa543081991ea.pdf} } @article { author = {Zorob, Fatma and El Baz, Nemat and Ismaeil, Abd El Mawgood A. and Radwan, Mona}, title = {Some Pharmacological And Histological Studies On The Effect Of Neostigmine Injected Intrathecally}, journal = {The Egyptian Journal of Hospital Medicine}, volume = {3}, number = {1}, pages = {56-79}, year = {2001}, publisher = {Pan Arab League of Continuous Medical Education}, issn = {1687-2002}, eissn = {2090-7125}, doi = {10.21608/ejhm.2001.18897}, abstract = {The spinal delivery of the cholinesterase inhibitor neostigmine yields analgesia and augments the analgesic effect of alpha-2 (-2) agonist. To assess its activity, histological and pharmacological studies were designed to define its effect in two species; rats and cats. Pharmacological assessment of intrathecally injected (it) neostigmine in cats showed a gradual increase in mean blood pressure (MBP) and heart rate (HR) at doses 2 – 16 g /kg while a decrease in MBP and HR occurred at doses 32 – 64 g /kg. The intrathecal injection of atropine and phentolamine abolished the increase in MBP and HR produced by (it) neostigmine (4 g /kg). In spinal cat preparation (it) neostigmine produced rapid rise in MBP at small (4 g /kg) and large doses (64 g /kg). In this study neostigmine counteracts the hypotensive effect and bradycardia produced by intrathecal injection of -2 agonist clonidine. Histological study was performed on rats. They were divided into 5 groups representing control and 4 groups treated by neostigmine at 25, 50, 75 and 100 g/kg. After each injection, the animals were assessed for general behavior, and function. Arousal, motor coordination and motor tone measurement (A, MC and MT) revealed that Intrathecal injection of neostigmine resulted in dose-dependent decreased arousal, and motor coordination, and dose-dependent increase in motor tone. The quantitative histological and cytochemical data demonstrated an initial increase in the nucleo-cytoplasmic ratio of the anterior horn cells up to 75 ug/kg followed by a decline in 100 ug/kg- treated animals. The cytoplasmic RNA content of the anterior horn cells showed an increase in the optical density that reached a maximum at 50 ug/kg followed by a decline at higher doses. The Golgi bodies increased in the cytoplasm of 25 ug/kg treated animals, the level became constant up til 75 ug/kg, and started to decline at 100 ug/kg. There was no change in the quantity of the myelinated nerve fibers, however, there was a dose dependent decline in their stainability with silver.

Despite milrinone effectively increases cardiac function after cardiopulmonary bypass, few studies have specifically evaluated its efficacy during cardiac surgery. We investigated the effects of milrinone on hemodynamics and left systolic ventricular function in cardiac surgical patients immediately after emergence from cardiopulmonary bypass (CPB). Forty five patients undergoing cardiac surgery were studied. They received milrinone (25, 50, or 75 ug/kg) bolus dose over ten minutes followed by 0.25, 0.5, 0.75 ug/kg/min in three patients groups. Heart rate, mean arterial blood pressure, pulmonary capillary wedge pressure, and cardiac index were determined before and after the administration of milrinone and transesophageal echocardiogram were recorded while constant filling pressures were maintained by volume reinfusion from the CPB reservoir. All three doses of milrinone significantly increased CI ( 2.5, 3.1,3.2 L/min/m2 ), HR (98, 96,100 bpm), SV ( 61,66,67 ml/beat) and EF (61, 66, 66%) after 5 min from the milrinone use (p<0.001) and significantly decreased the MAP (80, 81, 82 mmHg), SVR ( 1127, 965, 928 dyn.s.cm-5) and PVR ( 183, 165, 157 dyn.s.cm-5) at the same time interval (p<0.001) while the PCWP and CVP did not show valuable change. The 50- and 75-ug/kg doses produced significantly larger increases in cardiac index than the 25-ug/kg dose; however, the 75 ug/kg dose did not produce a significantly larger increase in cardiac index than did the 50-ug/kg dose. Two patients receiving milrinone 25 ug/kg developed premature ventricular contractions. The 75-ug/kg dose was associated with a case of ventricular tachycardia treated with xylocaine infusion and three cases of severe hypotension (BP <60 mmHg) requiring phenylephrine infusion and IV fluid replacement. Thus, milrinone improves hemodynamics and left ventricular systolic function when constant loading conditions are maintained. }, keywords = {}, url = {https://ejhm.journals.ekb.eg/article_18900.html}, eprint = {https://ejhm.journals.ekb.eg/article_18900_3e49c119cea3910348db16f30275cec7.pdf} } @article { author = {El-Khayat, Mohsen M and Said, Zeinab N and El-Deeb, Gamal S and Sabry, Hany S and Radwan, Mamdoh M}, title = {Study Of The Relation Between Helicobacter Pylori Infection And Gastric Interleukin (8) In Patients With Chronic Liver Disease}, journal = {The Egyptian Journal of Hospital Medicine}, volume = {3}, number = {1}, pages = {90-106}, year = {2001}, publisher = {Pan Arab League of Continuous Medical Education}, issn = {1687-2002}, eissn = {2090-7125}, doi = {10.21608/ejhm.2001.18902}, abstract = {Helicobacter pylori (H pylori) is a gram negative spirally shaped bacterium. It is known to be the most common important cause of gastritis, peptic ulcer, non ulcer dyspepsia and gastric carcinoma. The frequency and importance of gastric mucosal lesion in patients with chronic liver disease (CLD) have been increasingly recognized in recent years. IL-8 a potent leukocyte chemo–attractant cytokine produced by H pylori. It promotes polymorphnuclear leucocytes (PMNs) and mononuclear cells (MNCs) accumulation in gastric mucosa.This work aimed to clarify the relation between H pylori and IL-8 production in various chronic liver disease (CLD) lesions. Eighty patients were included in this study, 50 with CLD and 30 dyspeptic patients without CLD. Gastric mucosal biopsies were examined histopathologically for H pylori, cellular infiltration and associated pathology, together with culture of H pylori and assessment of IL-8 level in gastric tissue supernatant. 30/50 (60%) CLD patients,10/15 (66.6%) patients with non gastric dyspepsia, and 14/15 (93.3%) patients with gastric dyspepsia were positive for H pylori. There was no relationship between the prevalence of H pylori and the aetiology of CLD. No significant difference was observed in CLD patients’ group as regard to H pylori and Child grading, degree of varices, gastric or liver histopathology. Statistical difference in H pylori prevalence between patients with CLD and those with gastric dyspepsia was significant. IL-8 showed significant increase in H pylori positive vs H pylori negative patients. Positive correlation was found between H pylori density and tissue IL-8 and cellular infiltration.

The present study also sheds light on the risk of using over-dosage either by mistake or in an unwise attempt at quick relieving the body pain. The intramuscular therapeutic dose of ketoprofen to albino rat was calculated and was found to equal 13.5 mg /kg body weight. Fifty adult male albino rats, Rattus norvegicus were used in the present study. The rats were equally allocated to five groups, each of 10 rats. Rats of the first group were kept as control. Rats of the second & third groups were injected daily with the therapeutic dose of ketoprofen for four and eight successive weeks respectively. Rats of the fourth & fifth groups were injected daily with double the therapeutic dose of ketoprofen for four and eight successive weeks respectively. In rats given the therapeutic dose of ketoprofen daily for four weeks and sacrificed 24 hours after the last dose, light microscope examination showed that Malpighian corpuscles and the kidney tubules revealed signs of degeneration. In rats given the therapeutic dose of ketoprofen daily for eight weeks the histological changes were in progression. A few numbers of glomeruli were increasingly congested and shrunken into dense masses of unrecognized structural details. The luminal borders of the cells lining the proximal convoluted tubules together with their microvilli were damaged. The electron micrographs of ultrathin sections of kidneys of rats given the therapeutic dose of ketoprofen daily for eight weeks showed that the glomerular capillaries were disorganized and occasionally their lining endothelium showed degeneration. The podocytes showed deteriorated and rarefied cytoplasm; and their primary processes were fragmented. Also, the foot processes appeared occasionally broad. In some cells of proximal convoluted tubules the microvilli completely disappeared. Occasionally, these cells gave broad blebs into the tubule lumen which became almost obliterated. The cytoplasm of few cells lining the distal convoluted tubules became moderately rarefied and vacuolated. In animals given double the therapeutic dose for four weeks many kidney glomeruli were fragmented and showed marked congestion and increased mesangium. The parietal walls of Bowman’s capsules were damaged. The kidney tubules showed generalized hyalinization. A few numbers of t he tubule lining cells displayed pyknotic nuclei; some nuclei were karyolysed and even vanished. In animals given daily double the therapeutic dose of ketoprofen for eight successive weeks, the glomeruli were sclerotic and necrotic and the kidney tubules showed generalized hyalinization. }, keywords = {}, url = {https://ejhm.journals.ekb.eg/article_18909.html}, eprint = {https://ejhm.journals.ekb.eg/article_18909_bcda4a7f593f3df6f1ee21965d180791.pdf} } @article { author = {Kotb, Bassem S.}, title = {Comparative Study On The Effect Of Some Histological Techniques On The Quantitative Morphometric Analysis}, journal = {The Egyptian Journal of Hospital Medicine}, volume = {3}, number = {1}, pages = {177-189}, year = {2001}, publisher = {Pan Arab League of Continuous Medical Education}, issn = {1687-2002}, eissn = {2090-7125}, doi = {10.21608/ejhm.2001.18911}, abstract = {Quantitative morphometric studies are commonly used nowadays in histological and pathological labs and researches. The aim of the study was to evaluate the possible effect of the histological techniques on the morphometric results and determination of correction coefficients of morphometric parameters in dependence on the histological procedure used. The organs and cells subjected to study were ; human RBCs (lack of nuclei), albino rats liver cells (active cells) and albino rat uterus (for gross study and its muscles and fibers content). Three techniques were selected; fresh cells (blood smear and liver cell print), frozen technique and paraffin sections fixed in neutral buffered formol (common histological technique). Quantitative morphometric analysis parameters selected were diameter, perimeter, area and area percent. The obtained results were statistically analyzed by using student paired t-Test. The study showed statistically significant changes in quantitative morphometric results under the effect of histological techniques used. Frozen technique increased the morphometric results , while paraffin technique decreased them when compared with those of fresh data. Also the morphometric data of gross area and perimeter of organs affected by their fibrous elements. The study concluded that all quantitative morphometric results must be corrected by a coefficient factor which depends on the organ and technique used before analysis and evaluation of data. }, keywords = {}, url = {https://ejhm.journals.ekb.eg/article_18911.html}, eprint = {https://ejhm.journals.ekb.eg/article_18911_2c0e40876d5226f16ee55f70066b1100.pdf} } @article { author = {Soliman, Nabil A.}, title = {Effect of experimentally induced diabetes mellitus on serum leptin level and the role of insulin replacement therapy}, journal = {The Egyptian Journal of Hospital Medicine}, volume = {3}, number = {1}, pages = {190-208}, year = {2001}, publisher = {Pan Arab League of Continuous Medical Education}, issn = {1687-2002}, eissn = {2090-7125}, doi = {10.21608/ejhm.2001.18912}, abstract = {The regulation of circulating leptin concentration is multifactorial and still understood. Therefore, the present study was designed: (1) to demonstrate the effect of gender on leptin concentration in intact control rats, (2) to evaluate the relationship between serum leptin concentration, serum insulin level and body weight in control rats and streptozotocin (STZ) diabetic rats (untreated and treated with insulin). A total number of 48 healthy adult albino rats of both sexes (24males& 24 females) were used in this study. The animals were divided equally into four groups, each group was subdivided equally into -male and female subgroups. Group 1(G1): served as control group, group 2(G2): experimental diabetics group (not treated) and group 3(G3) & group 4(G4): experimental diabetic group treated with insulin for 2 and 21 days. These groups were examined for the following parameters: body weight, blood glucose level, serum insulin and leptin concentration. It was found that serum leptin level was significantly higher in female than in male control group. However, this difference could not be detected in between male and female rats in all other studied groups. Moreover, a strong positive correlation was found between leptin concentration and insulin hormone level, and body weight in control male and female rats. STZ-induced diabetes associated with a significant rapid decrease in circulating leptin concentration (G2), this decrease was accompanied with a significant decrease in both serum insulin level and body weight, then, it was rapidly reversed by insulin treatment for 2days (G3) and 21 days (G4). There was also a positive correlation between serum leptin concentration, body weight and serum insulin level in this diabetic group. However, leptin was found to change in an inverse proportion to the variation in blood glucose concentration in both male and female diabetic groups. The direct relationship of serum leptin concentration to serum insulin concentration and the inverse relationship of leptin concentration to blood glucose level were preserved in both male and female insulin replacement therapy groups. In conclusion, in adult albino rats, several factors are involved in the regulation of circulating leptin level such as gender, body weight, blood glucose level and serum insulin concentration. }, keywords = {}, url = {https://ejhm.journals.ekb.eg/article_18912.html}, eprint = {https://ejhm.journals.ekb.eg/article_18912_fa68ba0696f2fa5c9f8a9b2d3192dab8.pdf} }
