Prolonged pregnancy. Review of the literature

There have been various estimations of the frequency of postdate pregnancies. On the average, 10% of all pregnancies exceed 42 weeks amenorrhoea with a range from 4 to 14% according to the authors. Rates vary with use of ultrasound examinations early, avoiding false dating and induced labour. A pregnancy becomes a pregnancy at risk at the end of the 41st week of amenorrhoea. Fetal maturity may be affected by a disease process or due to individual or ethnic variations. The potential danger of prolonged pregnancy is inhalation of meconium prepartum. Expulsion of meconium is both a frequent consequence of fetal distress and the result of increased intestinal reactivity. There does not appear to be agreement on the degree of risk of sudden death at the end of pregnancy, although the risk does appear to exist. Surveillance should include recording fetal heart rate under basal conditions and an assessment of the amniotic fluid volume with ultrasounds. The Doppler technique is currently under study. When the status of the cervix is favourable, labour may be induced by rupturing the membranes of with a perfusion of Syntocinon. When the status of the cervix is unfavourable, prostaglandin E2 is applied intravaginally or intracervically with a gel. Therapeutic trial published to date do not demonstrate any advantage over cesarean section or fetal morbidity. The safety of the procedure has not been proven. Randomized trials comparing systematic induction of labour with a wait-and-see attitude have not given a definitive answer. Only two trial have shown a significant advantage of systematic induction of labour. The others have shown that the rate of cesarean section and neonatal morbidity are comparable in the two groups.     

Coffin-Siris syndrome. Review of the literature

A great deal of new information has become available in the field of hypertension since the JNC report of 1988. The JNC V report has changed the categorization of blood pressure, modified suggested drugs for initial therapy, and recommended that diuretics or beta blockers be considered the first-line drugs of choice. Information concerning the J curve and end-stage renal disease has made therapeutic goals more challenging. One of the most important additions to this report is the new information on treating elderly patients, which had been lacking until last year. The report calls on pharmacists to assist with detecting, evaluating, and referring hypertensive patients. Pharmacists must take a leadership role in promoting compliance with antihypertensive therapy and can assist other health-care professionals by suggesting therapeutic alternatives to improve efficacy, reduce the frequency of administration, and lower costs. The complete JNC V report is an essential reference for the files of any pharmacist who is responsible for the care of hypertensive patients.     

Clinical, etiologic and therapeutic aspects of chronic sphenoid opacities

PURPOSE: The purpose of this study was to review abstracts accepted for presentation at the annual national meeting of the Society for Adolescent Medicine (SAM) over the past 3 decades for subject content and research design. METHODS: Retrospective review was conducted of research abstracts for 3 years, selected at random, for the 1990s and then matched at 10-year intervals for the previous 2 decades. The major categories for subject content were: medical, psychosocial, health services, and miscellaneous; for research design categories were: retrospective, observational, experimental, and miscellaneous. Subsequent publication was also assessed. RESULTS: The most notable change over the 3 decades in subject content was a shift from medical topics (58% to 19%) to psychosocial topics [20% to 52% (p < .001)] of abstracts, the latter largely accounted for by increases in topics pertaining to high-risk behaviors. There was a substantial decrease in abstracts concerning medical aspects of chronic illness (p < .001), well-adolescent care, growth and development, and psychosocial aspects of chronic illness (p < .02). Regarding research design, the proportion of retrospective studies decreased over the 3 decades (p < .02); the most prevalent design was observational, with an increase in studies using established databases (p < .02). Less than 15% represented an experimental design. Studies using qualitative analysis appeared for the first time in the 1990s. The percentage of presentations which eventuated in published reports increased from 35% to 63% over the 3 decades (p < .02). CONCLUSION: A significant shift occurred in subject content of scientific abstracts from a medical to a psychosocial emphasis. The proportion of retrospective designs decreased, and qualitative analyses emerged. The likelihood of later publication of the studies increased.     

Ultrastructural observation on the uncinate process of chronic sinusitis

The ultrastructures of the uncinate processes (UP) obtainel from 16 patients with clinical diagnosis of chronic sinusitis were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results showed that there were three main surface cell types on the UP: Most of the cilia was leaned, fractured and in disorder; Gaps of the cells increased obviously; Squamous cell metaplasia was seen; The endoplasmic reticulums and mitochondria in cytoplasm were expanded moderatly or seriously. The morphological changes indicated that mucus transportation functions in the anterior ethmoid region and the middle meatus were damaged. It is of great importance in occurrence and development of chronic sinusitis. The demaged nasal mucosa epithlial cells are repairable and reproducible.     

Home rehabilitation after stroke. Review of the literature

To find an answer to the question whether domiciliary rehabilitation after stroke is better or cheaper than alternative forms of rehabilitation, a systematic literature review of controlled trials was performed. Three large and two smaller, more preliminary studies of all together a thousand patients were found and regarded methodologically acceptable. Efficacy as regards functional, emotional and qualitative outcome of patients was equivalent for various modes of care. So was the degree of stress, social function and quality of life for the main carers. Home treatment costed less than regular day care but more than routine care including a mixture of outpatient and day care, as considered required. Domiciliary rehabilitation seems to be a good and cost effective alternative for stroke patients who need and cannot manage frequent out-patients visits without ambulance or other exhausting and expensive transports.     

Melanoma of the oral cavity. Review of the literature

The location of melanoma in the oral cavity is extremely rare: its frequency varies between 0.2 and 8%. Oral melanoma strikes mainly male subjects and is more frequently seen at the level of the hard palate and gingiva. Today the clinicopathological classification of oral melanoma is not yet clearly outlined, and that is why the skin form is often taken as a reference. The acral lentiginous subtype proves to be the most common in this seat. In many cases (up to 50%) the diagnosis of melanoma is made on lesions which have evolved from the pre-existing pigmented lesions: as a consequence, every pigmented lesion of undetermined origin must be biopsied as a routine. The prognosis often proves poor and the surgical approach, combined with the chemotherapeutic one, is the first choice treatment. Lymph node dissection is not routinely practiced.     

Counseling and psychotherapy with Asian-Americans: Review of the literature.

Reviews the existing literature on counseling and psychotherapy with Asian-Americans and discusses research needs and recommendations for future research. Diagnosis and assessment issues include symptom expression, therapist bias, problems with the use of interpreters, and problems with the use of clinical and personality tests. Client variables in counseling and psychotherapy involve the personality of Asian-Americans, language problems, the acculturation process, and counseling expectations. Therapist variables involve therapist bias, training bias, lack of intercultural skills, and culture-specific knowledge. In a discussion of process and outcome, the author reviews empirical studies, clinical case studies, and articles with treatment strategies and recommendations. Research recommendations for each of the areas reviewed are identified. (3 p ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Saliva: clinical and diagnostic usefulness. Review of the literature

Modern clinical pathology is mainly based on the analysis of blood samples, carried out through more and more sophisticated techniques. Being the blood test an invasive technique, it certainly reduces the possibility of carrying out blood analysis, especially in patients such as children, old people, handicapped people and every person who needs continuous biochemical or pharmacological monitoring. In these cases it is very important to find other body fluids that can be easily obtained and that can offer the same reliable data as blood. Due to some of its characteristics, sometime saliva may be a good alternative to venous blood, as it presents the same features of plasma or urine. The chemical analysis of saliva provides some information that are useful for metabolic, inflammatory, neoplastic and genetic diseases; furthermore radioimmunological dosages allow to assess small concentrations of active substances. On the basis of an accurate review of literature, the aim of this study is to analyse the importance of saliva in diagnosing and monitoring certain systemic diseases, the utilization of saliva in hormonal and pharmacological dosages and the use of saliva in some epidemiological studies. Finally, it is emphasized that saliva in monitoring may help to manage several clinical conditions.     

Pharmacologic therapy of cranio-cervico-mandibular disorders. Review of the literature

Enzymes are essential to life and catalyze various metabolic activities. They find application in a number of diseased conditions, and their scope is being widened as knowledge develops.     

Nasal mucociliary transport of chronic sinusitis in children

Nasal mucociliary function is one of the most important and indispensable mechanisms of the respiratory tract, providing protection against the atmospheric environment. We previously found mucociliary dysfunction in the noses of adult patients suffering from chronic sinusitis. In this study, using the saccharin method, we determined nasal mucociliary function in normal children and in children with chronic sinusitis. The mean (+/- SD) value of saccharin transit time in the nose was 28.2 +/- 19.9 minutes in patients with chronic sinusitis, this being significantly slower than that in the control group of children. The incidence of abnormally slow nasal mucociliary transport time (> 30 minutes) in patients was significantly higher than in controls of the same age. Mucociliary dysfunction may initiate a vicious cycle of self-mediated inflammation and may be important in recovery from chronic respiratory inflammation.     

Drug therapy of hemiballism. Review of the literature and personal observations

Hemiballism is a rare hyperkinetic disorder which is characterized by irregular vigorous rotatory movements of the limbs of one side of the body. The disabling and exhausting movements with their high risk of severe injuries require an acute drug treatment. However, there are no common guidelines for the treatment of this disorder. Therefore we reviewed the available literature to establish a concept for a rational symptomatic drug treatment. Furthermore, own observations in 6 patients with hemiballism of different origins are reported.     

Sclerosing lesion of the sphenoid bone. Fibrous dysplasia of the sphenoid bone of the sclerosing type]

A 3-year-old Quarter Horse gelding was treated for left guttural pouch mycosis by ligation and balloon catheterization of the left internal carotid artery. Catheter advancement was shorter (10 cm) than the normally reported distance (13-15 cm), but was observed endoscopically during placement as it coursed within the internal carotid artery through the guttural pouch. The horse developed a persistently abnormal respiratory pattern after catheter placement, failed to gain consciousness, developed pulmonary edema, and died 5.5 hours postoperatively. Postmortem examination revealed an aberrant left internal carotid arterial course with location of the embolectomy catheter at the junction of the basilar and caudal cerebellar arteries. Brainstem neuronal necrosis and alveolar and interstitial pulmonary edema were identified on histological examination. Angiography may be used to identify aberrant branching patterns. Failure to identify and occlude aberrant branches may result in fatal epistaxis and Brainstem lesions.     

Invasive mold sinusitis: 17 cases in immunocompromised patients and review of the literature

A 10-year retrospective analysis of invasive mold infections in hospitalized patients was performed to characterize the epidemiology and clinical features of invasive fungal sinusitis. Seventeen cases of invasive mold sinusitis were identified. Eleven cases were caused by Aspergillus flavus, three were caused by unspecified species, and one each was caused by Aspergillus fumigatus, Rhizopus species, and Alternaria species, respectively. Fifteen patients had hematologic malignancies, and two had end-stage liver disease. The most common presenting symptom was periorbital swelling (seven patients). Sinusitis was diagnosed a median of 19 days after admission. Eight patients (47%) survived; six of these patients were treated with both amphotericin B and surgery. Postmortem examination of six patients showed evidence of disseminated disease; the brain was the most common extrapulmonary site (four patients). To our knowledge, this is the largest currently reported series on invasive mold sinusitis; our report extends the information on invasive mold sinusitis and shows that aggressive therapeutic and surgical interventions are needed to prevent rapid progression of disease in immunocompromised patients.
