Sleep-related breathing disorders in children are common. Nearly 10% of preschool-aged children snore, and 1% of 4- to 5-year-old children present with an obstructive sleep apnea syndrome (OSAS), mostly due to an adenotonsillar hyperplasia. OSAS in children differs markedly from adults concerning etiology, clinical symptoms, polysomnographic findings, and course of the disease. Therefore, results of adult sleep medicine cannot easily be applied to children. The disease may result in pulmonary or systemic hypertension, failure to thrive, and neurocognitive misbehavior. Up to now, there is no consensus concerning diagnosis and therapy. In this article, we summarize and discuss what is known so far about sleep-related breathing disorders in children, focussing on the OSAS as the most important diagnosis for the ENT specialist.

Hypertension, hyperinsulinaemia and dyslipidaemia are strong and independent risk factors for cardiovascular diseases. Their increasing frequency in postmenopausal women suggests that oestrogen deficiency may be a contributing factor. It is well known that oestrogen replacement therapy in postmenopausal women improves carbohydrate and lipid metabolism, but the effect of combined hormone replacement therapy (HRT) remains unclear. The purpose of the present study was to evaluate the effect of HRT on blood pressure, carbohydrate metabolism and lipid profile in postmenopausal women with primary arterial hypertension. The study population consisted of 76 postmenopausal women (mean age 51.1 +/- 6.8 years). Forty hypertensive women received HRT (17-beta-oestradiol, norethisterone acetate, TTS, Estracomb Novartis), whereas 36 women remained without hormonal therapy. One-year combined transdermal HRT did not affect significantly blood pressure and blood pressure variability. HRT was shown to improve lipid profile with a significant decrease in total cholesterol as early as at 3 months. It does not influence carbohydrate metabolism parameters studied by glycaemia and insulinaemia in a standard oral glucose tolerance test. In conclusion, combined percutaneous HRT may reduce the lipid-depended cardiovascular risk in postmenopausal women with arterial hypertension.

Seventy-eight workers, drawn from a population of 1502 presumably healthy working men who were interviewed about sleep habits and sleep disorders, underwent polygraphic recordings for at least 1 night. A significant association was found between the complaint of excessive daytime sleepiness and the incidence of sleep apnea. Workers with more than 10 apneas per hour of sleep complained significantly more about loud snoring, hypermotility in sleep, and frequent headaches. They had significantly more ENT findings and hypertension.

Outlined is a protocol for the administration of emergency contraceptive pills. The indication for such treatment is unprotected intercourse within the past 72 hours. Absolute contraindications include the possibility of an existing pregnancy and a family history of stroke, heart attack, thrombophlebitis, breast or endometrial cancer, or liver tumor. Possibly excluded, depending on evaluation by a physician, are women with abnormal vaginal bleeding, active hepatitis, active gallbladder disease, high blood pressure, acute focal migraine, breastfeeding women, and those unable to understand instructions. The recommended regimen consists of six tablets of Ovral (two taken immediately, two more in 12 hours) or 12 tablets of Lo/Ovral, Nordette, or Levlen (four taken immediately, repeat dosage in 12 hours). The extra pills are to be used in cases of vomiting within three hours of pill ingestion. Women with a history of oral contraceptive-related nausea and vomiting should be provided with Compazine. Women should be informed that this method is effective in only about 92% of cases. All women who receive emergency contraception should be counseled that this is strictly a back-up method and helped to formulate a long-term birth control strategy.

Numerous internal diseases can express themselves in the form of ENT manifestations. Epistaxis is one of the most common emergencies seen by the ENT specialist. Possible underlying systemic etiologies may be hypertension, systemic anticoagulation or even rare entities such as hereditary hemorrhagic telangiectasia. Internal-medical conditions underlying hoarseness are usually injuries to the recurrent nerve with lesions of the thyroid gland and mediastinum being prominent. Modern electrophysiological techniques permit early prognostication of the chances of healing a vocal cord paresis. A number of surgical procedures for improving vocal problems in the treatment of irreversible paresis are available. Unclear cervical swellings prompt a wide range of possible differential diagnoses that differ dramatically in terms of both treatment and outcome. For this reason, a rational, interdisciplinary diagnostic work-up is essential. In light of the risk of delaying the diagnosis and worsening the outcome, uncritical primary sampling of such tissue must be avoided.

Pre-eclampsia is one of the most common causes of perinatal and maternal morbidity and mortality. High blood pressure and proteinuria are important clinical signs of pre-eclampsia. Sympathetic overactivity and elevated level of circulating vaso active substances, such as monoamines has been shown. Extracellular concentrations of monoamines are normally kept low by specific transporter proteins of which many are expressed in the placenta. In this study we used in situ hybridization and real-time PCR to study the gene expression of monoamine transporters, such as NET, SERT, VMAT2, EMT and OCT1/2, in normal as well as in pre-eclamptic placentae. We demonstrated high expression of NET mRNA in the trophoblast cells of the anchoring villi and a lower expression intensity in the chorionic villi. SERT mRNA was mainly detected in chorionic villi. VMAT2 mRNA was not detected in the central part of the placenta but was present in the spiral arteries of placenta bed biopsies, in cytokeratin positive cells. EMT mRNA was mainly detected in the intra lobular septa and together with OCT1 and OCT2 mRNAs also expressed in scattered cells of placental vessel adventitias. Moreover, quantitative analysis showed a significant lower expression of NET and EMT mRNAs in pre-eclamptic placentae as compared to the control group. A defective gene expression or function of these monoamines transporters might explain the elevated concentrations of monoamines in pre-eclamptic patients. Monoamine transporters may serve as a protective mechanism preventing vasoconstriction in the placental vascular bed and thereby securing a stable blood flow to the fetus.

Economies in National Health Systems forces ENT surgeons to review their indications for outpatient tonsillectomy. Therefore, it is important to preoperatively identify special risk groups who frequently have extensive posttonsillectomy bleeding with the need of a blood transfusion. Aim of this study was to estimate the incidence for posttonsillectomy bleeding related blood transfusion, to identify risk factors associated with the need for blood transfusion and to release guidelines for posttonsillectomy bleeding of high risk patients. A retrospective study was done on the medical history of 1720 patients who underwent tonsillectomy for chronic tonsillitis between 1982-1993 in the ENT Department at the University of Kiel. The average transfusion rate was 0.52%. End Stage Renal Disease and hypertension combined with a preoperatively decreased Hb and Hct were the risk factors identified leading to a transfusion. These patients should not get a tonsillectomy as an outpatient procedure. The Hb, Hct, PT, PTT, blood type and crossmatch should be drawn and assessed prior to tonsillectomy. We recommend immediate treatment of secondary hemorrhage in those high risk patients under general anesthesia to avoid severe complications.

We report an extremely rare case of metastasic renal cell carcinoma to the temporal bone which presented initially as a jugulotympanic paraganglioma. The clinical and radiological appearances were misleading.Investigations of concomitant high blood pressure revealed a tumour of the right kidney. Biopsy of the mastoid mass was histologically compatible with a metastasis from a clear cell renal carcinoma. The patient underwent a radical nephrectomy and local external radiotherapy to the head. He also received adjuvant treatment with interferon-_ and interleukin 2. The clinical presentation, the radiological and histological features, the patterns of spread, the treatment options and the prognosis of these tumours are discussed. A review of the literature confirms the extremely unusual occurrence of this localisation.

New Information on Chronic Rhinosinusitis and Polyposis Nasi Chronic inflammation of the paranasal sinuses is more common than inflammatory or degenerative diseases of the joints or arterial hypertension. The pathogenesis of chronic rhinosinusitis has still not been completely worked out. It is known that in particular the administration of antibiotics is incapable of healing the condition. Once the diagnosis has been established by an ENT specialist, topical or systemic steroids may be helpful. In most cases, however, it is necessary to combine these substances with surgical treatment. For this purpose, endoscopic sinus surgery is an approach that is capable of providing good long-term results.

Pediatric migraine differs from adult migraine especially in regards to duration, localisation and quality of pain. A detailed description of the symptoms with a normal neurological examination allows in most cases to rule out secondary headaches without other exams. Many different medications are used for symptomatic or prophylactic treatment with success. Symptomatic headaches should be suspected if there is any abnormality in history or neurological exam. Headaches due to arterial hypertension, ENT problems or maxillofacial causes should not be forgotten. Intracranial hypertension should be excluded especially in children with ventriculo-peritoneal shunt, since shunt dysfunction can be fatal. Post traumatic headache can be impressive but have a good prognosis.
