Does Pregnancy Induce or Enhances Low Back Pain
(2006) Kiymaz, N.; Yilmaz, N.; Zeteroǧlu, Ş.; Yazici, T.
Forty-eight pregnant women out of 166 referred to our obstetrics and gynecology outpatient clinic due to back pain between February and March 2003 were included in the present study. A questionnaire booklet was prepared for age, weight gain during pregnancy, number of parities, existence of any back pain in their former pregnancies, the start of back pain during pregnancy, physical work conditions and route of previous labour information. These patients were followed for a period of 1.5 years after labour. The factors that influenced back pain in the pregnant patients were: multiparity, former back pain during pregnancy, and weight gain during pregnancy. We determined lumbar discopathy at a ratio of 79.1% using MRI (Magnetic Resonance Imaging) study of the lumbar vertebrae in patients with back pain lasting more than a one year. © 2006 VSP.
Hydrocephalus
(2008) Arslan, M.; Yazici, T.
Hydrocephaly is called increased intracranial pressure associated with enlarged ventricle as a result of imbalance between produce and absorption of Cerebral Spinal Fluid (CSF) which functions as a natural pillow in the brain. Prevalence is 1-1.5 percent. Hydrocephaly may depend on many cause including subnormal CSF reabsorbtion, increased CSF production, increased venous pressure, and obstruction in circulation of CSF. There is an increased CSF volume. Increased CSF volume results from imbalance between absorption and production of CSF. CSF produces in the choroid plexus and absorbs in the arachnoid villuses. The brain which is closely pressed in the cranium is damaged. Therefore, pressed brain tissue cannot function completely. Hydrocephalus may be obstructive type, which there is a obstruction in CSF pathways, and non obstructive type which there is not a obstruction in CSF pathways. The patient with hydrocephalus complains of nause, vomiting and headache. There may be also lethargy, unconscious, irritability, enlarged head circumference, growth and mental retardation findings. Dilated ventricle can be seen in CT and MRI. If it is not treated immediately, it may end with the death of the patient. Aim of the treatment of hydrocephalus is to reduce to intracranial volume to normal limits in order to provide normal brain development.
Sildenafil (Viagra) and a Rare Complication: Intracerebral Hemorrhage
(2007) Arslan, M.; Yazici, T.
Sildenafil is fist efective oral agent in treatment of erectil dysfunction. It relaxes the smooth muscles of the corpus cavernosum selectively by inhibiting phosphodiesterase type 5 and causes potential erection during sexual stimulation. Although its low dose is efective, the most effective dose is 50-100 mg. The use of sildenafil is associated with various complications. Using high-dose sildenafil in especially groups with risk may cause mortal complications. It reduces transiently the blood pressure. If it is used associated with nitrates, it may cause severe hipotension. The most frequent reported complications are headache, flushing, nasal kongestion, dispepsi and vision disorder. With painful and long-term erections are frequent seen. The side effects are transient. A 45 - year - old man was admitted to our hospital because of intraventricle hemorrhage after sildenafil use. To our knowledge, this rare complication related to sildenafil has never been reporded until now. Chronic sildenafil use causes disorder in the endotel layer of the vessel, also high dose sildenafil lead to vasodiladation extensively. Therefore, we believe that extensive vasodilatation due to high dose sildenafil in the defeated vessels causes rupture of cerebral arteries. Also undiagnosed cerebrovascular disease such as aneurysm, arteriovenous malformation, cavernous angioma may cause brain bleeding extensive excersize during sexual performance.
