Doxycycline-induced pill esophagitis

DISEASES OF THE ESOPHAGUS, Issue 2 2004
A. Kadayifci
SUMMARY., Pill-induced esophagitis is a complication seen in patients who use certain medications such as tetracycline and non-steroidal anti-inflammatory drugs. In this short report, we described five cases of doxycycline-induced esophagitis with endoscopic images. All of the patients were young or middle-aged women. Dysphagia or odynophagia with retrosternal pain were the main presenting symptoms in all cases. The observed injuries were at the middle third of esophagus with a normal surrounding mucosa. All patients had a history of swallowing the capsule with a small amount of water or in a recumbent position. Two patients with dysphagia were managed by intravenous fluid support and parenteral acid suppression. The symptoms were improved in 2,7 days after the ceasing of the drug and control endoscopies were completely normal in all cases after 3,4 weeks of admission. The drug-induced esophagitis is not rare with certain drugs and should be suspected in all patients presenting with chest pain and dysphagia. Physicians must warn the patients to take the pills and capsules with enough liquid and in the upright position. [source]

Asymptomatic leukocyturia and the autonomic nervous system in women

GERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 2 2009
Yoshimasa Igari
Background: The present study sought to investigate the relationship between asymptomatic leukocyturia (ASL) and autonomic nervous function by power spectral analysis of the R-R intervals in women. Methods: One hundred and forty-two female outpatients aged 23,91 years were studied. We regarded ASL to be present if two consecutive samples were found to have 10 or more leukocytes/high-power field at ×400 magnification in a centrifuged midstream urine sample. The R-R intervals of all subjects were measured by the wavelet transform analysis system. This system detected R-R variation data distributed in two bands: low-frequency power (LF) (0.04,0.15 Hz) and high-frequency power (HF) (0.15,0.40 Hz). The ratio of LF to HF (LF/HF) was also determined. Post-void residual urine volume was measured using an automated, compact 3-D ultrasound device. Results: The patients with ASL had diabetes mellitus more frequently than those without ASL. Residual urine volume was significantly higher in the former than in the latter, while the HF values in both a recumbent position and a standing position were significantly lower in the former than in the latter (P = 0.003, P = 0.001, respectively). However, there were no significant differences in LF or LF/HF values in either a recumbent or a standing position between the two groups. The HF values in both a recumbent position and in a standing position were independent indicators of ASL, even after adjustment for age, diabetes mellitus and residual urine volume. Conclusion: The present study reveals the relationship between ASL and impairment of the parasympathetic nervous system in women. [source]

Risk of perineal damage is not a reason to discourage a sitting birthing position: a secondary analysis

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 5 2010
A. De Jonge
Summary Aim:, To examine the association between semi-sitting and sitting position at the time of birth and perineal damage amongst low-risk women in primary care. Background:, Evidence on the association between birthing positions and perineal trauma is not conclusive. Most studies did not distinguish between positions during the second stage of labour and position at the time of birth. Therefore, although birthing positions do not seem to affect the overall perineal trauma rate, an increase in trauma with upright position for birthing cannot be ruled out. Methods:, Secondary analysis was performed on data from a large trial. This trial was conducted amongst primary care midwifery practices in the Netherlands. A total of 1646 women were included who had a spontaneous, vaginal delivery. Perineal outcomes were compared between women in recumbent, semi-sitting and sitting position. Logistic regression analysis was used to examine the effects of these positions after controlling for other factors. Findings:, No significant differences were found in intact perineum rates between the position groups. Women in sitting position were less likely to have an episiotomy and more likely to have a perineal tear than women in recumbent position. After controlling for other factors, the odds ratios (OR) were 0.29 [95% confidence interval (CI): 0.16,0.54] and 1.83 (95% CI: 1.22,2.73) respectively. Women in semi-sitting position were more likely to have a labial tear than women in recumbent position (OR: 1.43, 95% CI: 1.00,2.04). Conclusion:, A semi-sitting or sitting birthing position does not need to be discouraged to prevent perineal damage. Women should be encouraged to use positions that are most comfortable to them.

Effect of acute postural variation on diabetic macular oedema

ACTA OPHTHALMOLOGICA, Issue 2 2010
Martin Vinten
Abstract. Purpose:, This study aimed to study the pathophysiology of diabetic macular oedema (DMO) by analysis of concomitant changes in macular volume (MV), mean arterial blood pressure (MABP), intraocular pressure (IOP), and retinal artery and vein diameters in response to acute postural changes in patients with DMO and healthy subjects. Methods:, Thirteen patients with DMO (13 eyes) and five healthy subjects (five eyes) were examined after resting in a chair for 15 mins using optical coherence tomography to measure MV and fundus photography to assess retinal vessel diameters. The patients then lay down for 60 mins, during which they were examined repeatedly before they were reseated and examined again. Intraocular pressure was measured using pulse-air tonometry, arterial blood pressure by sphygomanometry and fluid columns using rulers and a spirit level. Results:, In healthy subjects, retinal artery (p = 0.02) and vein (p = 0.001) diameters decreased when subjects lay down, whereas MV remained stable. In patients with DMO, no orthostatic variation in retinal vessel diameters could be demonstrated, whereas MV had increased by 2.4 ± 0.6% (mean ± standard error of the mean; p = 0.006) 50 mins after assuming a recumbent position. In both healthy subjects and DMO patients, MABP decreased and IOP increased in a recumbent position, with no significant difference between the groups. Conclusions: The increase in MV that occurs in DMO when changing from a seated to a recumbent position is associated with a failure of retinal artery contraction, a response seen in healthy subjects that appears to counter-regulate the increase in ocular perfusion pressure caused by assuming a recumbent position.
