Frequency of gynecologic follow-up and cervical cancer screening in the Swiss HIV cohort study

BACKGROUND: According to current recommendations, HIV-infected women should have at least 1 gynecologic examination per year. OBJECTIVES: To analyze factors associated with frequency of gynecologic follow-up and cervical cancer screening among HIV-infected women followed in the Swiss HIV Cohort Study (SHCS). METHODS: Half-yearly questionnaires between April 2001 and December 2004. At every follow-up visit, the women were asked if they had had a gynecologic examination and a cervical smear since their last visit. Longitudinal models were fitted with these variables as outcomes. RESULTS: A total of 2186 women were included in the analysis. Of the 1146 women with complete follow-up in the SHCS, 35.3% had a gynecologic examination in each time period, whereas 7.4% had never gone to a gynecologist. Factors associated with a poor gynecologic follow-up were older age, nonwhite ethnicity, less education, underweight, obesity, being sexually inactive, intravenous drug use, smoking, having a private infectious disease specialist as a care provider, HIV viral load <400 copies/mL, and no previous cervical dysplasia. No association was seen for living alone, CD4 cell count, and positive serology for syphilis. CONCLUSIONS: Gynecologic care among well-followed HIV-positive women is poor and needs to be improved.

Gender differences in spontaneous cervical artery dissection

We analyzed sex differences in 696 patients with spontaneous cervical artery dissection. There were more men (n = 399; p < 0.0001), and men showed a higher frequency of hypertension (31% vs 15%; p < 0.0001). Women were younger (42.5 +/- 9.9 vs 47.5 +/- 9.3 years; p < 0.0001), had more often multiple dissections (18 vs 10%; p = 0.001), migraine (47 vs 20%; p < 0.0001), and tinnitus (16 vs 8%; p = 0.001). Outcome and mortality were similar in both sexes.

Seasonal variability in spontaneous cervical artery dissection

We examined the seasonal variability of spontaneous cervical artery dissection (sCAD) by analysing prospectively collected data from 352 patients with 380 sCAD (361 symptomatic sCAD; 305 carotid and 75 vertebral artery dissections) admitted to two university hospitals with a catchment area of 2,200,000 inhabitants between 1985 and 2004. Presenting symptoms and signs of the 380 sCAD were ischaemic stroke in 241 (63%), transient ischaemic attack in 40 (11%), retinal ischemia in seven (2%), and non-ischaemic in 73 (19%) cases; 19 (5%) were asymptomatic sCAD. A seasonal pattern, with higher frequency of sCAD in winter (31.3%; 95% confidence interval (CI): 26.5 to 36.4; p=0.021) compared to spring (25.5%; 95% CI: 21.1 to 30.3), summer (23.5%; 95% CI: 19.3 to 28.3), and autumn (19.7%; 95% CI: 15.7 to 24.1) was observed. Although the cause of seasonality in sCAD is unclear, the winter peaks of infection, hypertension, and aortic dissection suggest common underlying mechanisms.

[Parent satisfaction with a child and family-centered treatment program for primary headache in childhood and adolescence]

Patient satisfaction represents a significant outcome criterion in the context of systemic psychotherapeutic therapy research. This study investigated parent satisfaction with a psychosocial treatment program (comprising three components: child group therapy, parents' evenings, systemic family sessions) for pediatric primary headache (diagnosed according to IHS criteria). 10 weeks after the end of the treatment program, the parents were sent a questionnaire containing open questions and ten-point numerical rating scales. The sample comprised n=48 families. The return rate was 89%. The qualitative content analysis showed a hierarchical category system consisting of 3 major categories, 7 main groups and 69 sub-categories. The parents stated that they were satisfied with (1.) the effects of the treatment program, (2.) the specific treatment techniques and the medical and psychosocial headache-related information provided, and (3.) the therapeutic relationship. The mean satisfaction for all three therapy components on the ten-point numerical rating scale was 8.1 with a standard deviation of 2.0 (child headache group: 8.5; parents' evenings: 8.2; family sessions: 7.5). The results are discussed with reference to methodological aspects: avoidance of ceiling effects and social desirability in measuring customer satisfaction, order effects of items, weighting of the significance of satisfaction levels as an outcome criterion.

Cervical soft tissue imaging using a mobile CBCT scanner with a flat panel detector in comparison with corresponding CT and MRI data sets

OBJECTIVE: The aim of this study was to evaluate soft tissue image quality of a mobile cone-beam computed tomography (CBCT) scanner with an integrated flat-panel detector. STUDY DESIGN: Eight fresh human cadavers were used in this study. For evaluation of soft tissue visualization, CBCT data sets and corresponding computed tomography (CT) and magnetic resonance imaging (MRI) data sets were acquired. Evaluation was performed with the help of 10 defined cervical anatomical structures. RESULTS: The statistical analysis of the scoring results of 3 examiners revealed the CBCT images to be of inferior quality regarding the visualization of most of the predefined structures. Visualization without a significant difference was found regarding the demarcation of the vertebral bodies and the pyramidal cartilages, the arteriosclerosis of the carotids (compared with CT), and the laryngeal skeleton (compared with MRI). Regarding arteriosclerosis of the carotids compared with MRI, CBCT proved to be superior. CONCLUSIONS: The integration of a flat-panel detector improves soft tissue visualization using a mobile CBCT scanner.

Excision of high and mid cervical spinal cord arteriovenous malformations by anterior operation

Symptomatic cervical spinal arteriovenous malformations (AVMs) located on the anterior aspect of the spinal cord are rare and surgical removal of these AVMs presents considerable challenges and risks. Surgical techniques to date have usually been by posterior approach and lateral dissection around the cord or via midline myelotomy, both approaches involving cord manipulation and retraction and in the latter, dissection through the spinal cord. We present two teenage patients with symptomatic anteriorly placed mid to high cervical spinal AVMs and associated aneurysm in which excision of the AVMs and aneurysm was performed by an anterior approach using vertebrectomy/corpectomy. The first case had a small perimedullary glomus-type AVM with an aneurysm on the anterior aspect of the cord at the C3/4 level; excision was performed using a single level vertebrectomy/corpectomy, the patient remaining neurologically intact. The second case had a medium-sized juvenile AVM with an aneurysm, both perimedullary and intramedullary, centred at the C5/6 level; excision was performed using a two-level vertebrectomy/corpectomy with no deterioration in the marked pre-operative tetraparesis, which at long-term follow up had improved and stabilised. Anterior approaches have been recently described for treatment of anteriorly placed cervical arteriovenous fistulas (AVFs) and an intramedullary haemangioblastoma, but not as yet for spinal AVMs. These are the first two reported cases of anteriorly situated cervical AVMs successfully removed surgically by an anterior approach and with good neurological outcomes.

Course of psychological variables in whiplash injury--a 2-year follow-up with age, gender and education pair-matched patients

This study evaluated the course of psychological variables during a 2-year follow-up in patients after common whiplash of the cervical spine. From a sample of 117 non-selected patients with common whiplash (investigated on average 7.2 +/- 4.2 days after trauma) a total of 21 suffered trauma-related symptoms over 2 years following initial injury. These patients (symptomatic group) were compared with 21 age, gender and education pair-matched patients, who showed complete recovery from trauma-related symptoms during the 2-year follow-up (asymptomatic group). Both groups underwent standardised testing procedures (i.e., Freiburg Personality Inventory and Well-Being Scale) at referral, and at 3, 6 and 24 months. In the symptomatic group during follow-up no significant changes in rating of neck pain or headache were found. Significant differences between the groups and significant deviation of scores over time were found on the Well-Being and Nervousness Scales. There was a lack of significant difference between the groups on the Depression Scale, indicating a possible somatic basis for changes in psychological functioning in the investigated sample. With regard to scales of Extraversion or Neuroticism, there were neither significant differences between the groups nor significant deviation over time. These results highlight that patients' psychological problems are rather a consequence than a cause of somatic symptoms in whiplash.

[Acute headache in a case of cerebral cavernomas]

We report a case of a 52-year-old female patient with known cerebral cavernomas and acute headache. A cranial CT scan excluded an intracranial bleeding. Cavernomas are rare vascular malformations of the venous blood system (synon. cavernous angiomas) with a slow blood flow. Clinical manifestation is presented between an age of 30-50 years with mostly unspecific neurological symptoms like headache, nausea, vomiting and dizziness, but also epileptic seizures and bleedings may occur. In general, therapy is symptomatic. In cases of seizures, however, anticonvulsive treatment is indicated. Operation can be discussed for peripheral localized cavernomas with bleeding or for refractory seizures. If antiplatelet or anticoagulation therapy is necessary due to other diseases (coronary heart disease, atrial fibrillation, thrombosis, pulmonary embolism), cerebral cavernomas are not considered as an absolute contraindication. The risk for an ischemic stroke under atrial fibrillation (5-20%), for example, is higher than the risk for bleeding of a cerebral cavernoma under anticoagulation therapy.

[Vasculitis as a reason of chronic headache]

A 13-year-old girl presented to our emergency with a one week history of fever and skin rash and new onset of chorea for the last three days. There was a long standing history of right predominant headache; followed by personality change, fatigue, arthralgia and weight loss over the last few months. Previous investigations by head CT and ophthalmological examination did not explain the symptoms. Further investigations revealed peri- and pancarditis with aortic insufficiency, a renal involvement with elevated creatinin, protein- and hematuria and a hemolytic anemia. Diagnosis of lupus eythematodes was confirmed by high ANA, anti-dsDNS and Anticardiolipin antibodies. Within the first 48 hours after admission there was significant deterioration with reduced vigilance and dysarthria. MRI of the brain and dopplersonography of cerebral vessels showed a complete thrombosis of the right medial cerebral artery with a small net of collaterals, irregularities of the left cerebral artery due to vasculitis and several subacute leftsided ischemias. Immunosuppressive therapy with high-dose corticosteroids and cyclophosphamid together with antithrombotic therapy induced an improvement of neurologic, renal and cardiac function.

Treating sensitive cervical areas with ozone. A prospective controlled clinical trial

PURPOSE: To determine whether the treatment of hypersensitive teeth with gaseous ozone (Healozone, KaVo 1600 ppm) for 60 seconds reduces pain immediately after treatment and in the longer term. METHODS: In three private practices in Switzerland, 31 subjects suffering from hypersensitive teeth were treated with gaseous ozone over a period of 54 weeks (one test and one control tooth in each subject). A cross-over design was chosen. The pain level was measured with a Visual Analogue Scale before and after the treatment. RESULTS: The subjects' pain level was reduced by 55% +/- 5.5% immediately after the ozone treatment. Over time, the pain level decreased significantly in all groups: The pain level in the test teeth was significantly reduced in Weeks 0-22 (treatment group, P < 0.001) compared to the pain level before treatment. The pain level in the control group was also reduced significantly over time in Weeks 0-22 (no-treatment, P = 0.025) and in Weeks 22-54 (treatment group, P = 0.0065). Comparing test and control teeth over time, there was no statistically significant difference in pain reduction (P = 0.58).

Clinical presentation of a traumatic cervical spine disc rupture in alpine sports: a case report

ABSTRACT: Isolated non-skeletal injuries of the cervical spine are rare and frequently missed. Different evaluation algorithms for C-spine injuries, such as the Canadian C-spine Rule have been proposed, however with strong emphasis on excluding osseous lesions. Discoligamentary injuries may be masked by unique clinical situations presenting to the emergency physician. We report on the case of a 28-year-old patient being admitted to our emergency department after a snowboarding accident, with an assumed hyperflexion injury of the cervical spine. During the initial clinical encounter the only clinical finding the patient demonstrated, was a burning sensation in the palms bilaterally. No neck pain could be elicited and the patient was not intoxicated and did not have distracting injuries. Since the patient described a fall prevention attempt with both arms, a peripheral nerve contusion was considered as a differential diagnosis. However, a high level of suspicion and the use of sophisticated imaging (MRI and CT) of the cervical spine, ultimately led to the diagnosis of a traumatic disc rupture at the C5/6 level. The patient was subsequently treated with a ventral microdiscectomy with cage interposition and ventral plate stabilization at the C5/C6 level and could be discharged home with clearly improving symptoms and without further complications.This case underlines how clinical presentation and extent of injury can differ and it furthermore points out, that injuries contracted during alpine snow sports need to be considered high velocity injuries, thus putting the patient at risk for cervical spine trauma. In these patients, especially when presenting with an unclear neurologic pattern, the emergency doctor needs to be alert and may have to interpret rigid guidelines according to the situation. The importance of correctly using CT and MRI according to both - standardized protocols and the patient's clinical presentation - is crucial for exclusion of C-spine trauma.
