Endoscopic endonasal approach for pituitary adenoma: surgical complications in 301 patients

The authors investigate the complications of transnasal transsphenoidal endoscopic surgery in the treatment of 301 patients with pituitary adenomas. A retrospective analysis of complications in 301 patients submitted to transsphenoidal transnasal endoscopic surgery at the General Hospital of Fortaleza, Brazil between January 1998 and December 2009. The complications were divided in two groups: anatomical (oronasofacial, sphenoid sinus, intrasellar, suprasellar and parasellar) and endocrinological complications (anterior and posterior pituitary dysfunctions). We observed a total of 81 complications (26.9%) in our series. Anatomical complications occurred in 8.97% (27 cases): 8 CSF postoperative leaks (2.6%), 6 cases (1.9%) of delayed nasal bleeding, 5 cases (1.6%) of sphenoidal sinusitis, 3 cases (0.9%) of carotid artery lesion, 2 cases of meningitis (0.6%) and one case (0.3%) of each of the uncommon following complications: intrasella-suprasella hematoma, pontine hematoma and chiasmaplexy. Endocrinological complications occurred in 17.9% (54 cases): additional postoperative anterior lobe insufficiency in 35 cases (11.6%), and postoperative diabetes insipidus in 19 cases (6.3%). In our series, 3 cases of deaths (not directly related to the procedure) were also observed. Endoscopic transsphenoidal surgery represents an effective option for the treatment of patients with pituitary tumor. Complications still occur and must be reduced as much as possible. Successful endoscopic pituitary surgery requires extensive training in the use of an endoscope and careful planning of the surgery. Additional improvement can be expected with greater experience and new technical developments.

Meaning of aromatherapy massage in mental health

Objective: To understand the meaning of the aromatherapy massage intervention in mental health for the patient during psychiatric hospitalization.Methods: A qualitative study including 22 participants with a diagnosis of personality disorder hospitalized in a psychiatric unit of a general hospital. We used semi-structured interviews with a guiding question for participants, for whom the aromatherapy massage intervention was performed. The content of the interviews was assessed according to content analysis.Results: Among the study subjects, there was a predominance of females and the majority presented a diagnosis of Emotionally Unstable Personality Disorder. Two categories that emerged were identified from qualitative data: "Identifying the benefits of aromatherapy" and "Enabling self-knowledge."Conclusion: The meaning of the aromatherapy massage intervention was represented by improvements in nursing care and treatment during psychiatric hospitalization, while assisting in the reduction of anxiety symptoms and coping with mental illness.

Association between sleep quality and quality of life in nursing professionals working rotating shifts

Objective: To analyze the association between sleep quality and quality of life of nursing professionals according to their work schedules. Methods: A prospective, cross-sectional, observational study was conducted between January and December 2010, with 264 nursing professionals, drawn from 989 subjects at Botucatu General Hospital and stratified by professional category. The Pittsburg Sleep Quality Index and the WHOQOL-bref were administered to evaluate sleep quality and quality of life, respectively. Self-reported demographic data were collected with a standard form. Continuous variables were reported as means and standard deviations, and categorical variables were expressed as proportions. Associations were evaluated using Spearman's correlation coefficient. The association of night-shift work and gender with sleep disturbance was evaluated by logistic regression analysis using a model adjusted for age and considering sleep disturbance the dependent variable. The level of significance was p < 0.05. Results: Night-shift work was associated with severe worsening of at least one component of sleep quality in the model adjusted for age (OR = 1.91; 95% CI 1.04; 3.50; p = 0.036). Female gender was associated with sleep disturbance (OR = 3.40; 95% CI 1.37; 8.40; p = 0.008). Quality of life and quality of sleep were closely correlated (R = -0.56; p < 0.001). Conclusions: Characteristics of the nursing profession affect sleep quality and quality of life, and these two variables are associated.

Cardiovascular risk factors in patients with first-episode psychosis in Sao Paulo, Brazil

Objective: The objective was to evaluate the cardiovascular profile of first-episode psychosis patients in Sao Paulo, Brazil, an issue that has not been sufficiently explored in low-/middle-income countries. Method: A cross-sectional study was performed 1 to 3 years after an initial, larger survey that assessed first-episode psychosis in sao Paulo. We evaluated cardiovascular risk factors and lifestyle habits using standard clinical examination and laboratory evaluation. Results: Of 151 contacted patients, 82 agreed to participate (mean age=35 years; 54% female). The following diagnoses were found: 20.7% were obese, 29.3% had hypertension, 39.0% had dyslipidemia, 19.5% had metabolic syndrome, and 1.2% had a >20% 10-year risk of coronary heart disease based on Framingham score. Also, 72% were sedentary, 25.6% were current smokers, and 7.3% reported a heavy alcohol intake. Conclusion: Compared to other samples, ours presented a distinct profile of higher rates of hypertension and diabetes (possibly due to dietary habits) and lower rates of smoking and alcohol intake (possibly due to higher dependence on social support). Indirect comparison vs. healthy, age-matched Brazilians revealed that our sample had higher frequencies of hypertension, diabetes and metabolic syndrome. Therefore, we confirmed a high cardiovascular risk in first-episode psychosis in Brazil. Transcultural studies are needed to investigate to which extent lifestyle contributes to such increased risk.

Assessment of referrals to an OT consultation-liaison service: a retrospective and comparative study

The objective was to conduct a retrospective and comparative study of the requests for consultation-liaison (RCLs), during a period of six years, sent to the Occupational Therapy (OT) team that acts as the Consultation-liaison Service in Mental Health. During the studied period 709 RCLs were made and 633 patients received OT consultations. The comparison group was extended to 1 129 consecutive referrals to the psychiatric CL service, within the same period and that were also retrospectively reviewed. Regarding to RCLs to the OT team, most of the subjects were women with incomplete elementary schooling, with a mean age of 39.2 years, and were self-employed or retired. Internal Medicine was responsible for most of the RCLs. The mean length of hospitalization was 51 days and the mean rate of referral was 0.5%, with the most frequent reason for the request being related to the emotional aspects and the most frequent psychiatric diagnosis was mood disorder. It is concluded that there is a clear demand for the development of consultation-liaison in OT, particularly with regard to the promotion of mental health in general hospitals.

Fiber architecture in remodeled myocardium revealed with a quantitative diffusion CMR tractography framework and histological validation

Background: The study of myofiber reorganization in the remote zone after myocardial infarction has been performed in 2D. Microstructural reorganization in remodeled hearts, however, can only be fully appreciated by considering myofibers as continuous 3D entities. The aim of this study was therefore to develop a technique for quantitative 3D diffusion CMR tractography of the heart, and to apply this method to quantify fiber architecture in the remote zone of remodeled hearts. Methods: Diffusion Tensor CMR of normal human, sheep, and rat hearts, as well as infarcted sheep hearts was performed ex vivo. Fiber tracts were generated with a fourth-order Runge-Kutta integration technique and classified statistically by the median, mean, maximum, or minimum helix angle (HA) along the tract. An index of tract coherence was derived from the relationship between these HA statistics. Histological validation was performed using phase-contrast microscopy. Results: In normal hearts, the subendocardial and subepicardial myofibers had a positive and negative HA, respectively, forming a symmetric distribution around the midmyocardium. However, in the remote zone of the infarcted hearts, a significant positive shift in HA was observed. The ratio between negative and positive HA variance was reduced from 0.96 +/- 0.16 in normal hearts to 0.22 +/- 0.08 in the remote zone of the remodeled hearts (p<0.05). This was confirmed histologically by the reduction of HA in the subepicardium from -52.03 degrees +/- 2.94 degrees in normal hearts to -37.48 degrees +/- 4.05 degrees in the remote zone of the remodeled hearts (p < 0.05). Conclusions: A significant reorganization of the 3D fiber continuum is observed in the remote zone of remodeled hearts. The positive (rightward) shift in HA in the remote zone is greatest in the subepicardium, but involves all layers of the myocardium. Tractography-based quantification, performed here for the first time in remodeled hearts, may provide a framework for assessing regional changes in the left ventricle following infarction.

Constipation Is More Frequent Than Diarrhea in Patients Fed Exclusively by Enteral Nutrition: Results of an Observational Study

Background: Digestive complications in enteral nutrition (EN) can negatively affect the nutrition clinical outcome of hospitalized patients. Diarrhea and constipation are intestinal motility disorders associated with pharmacotherapy, hydration, nutrition status, and age. The aim of this study was to analyze the frequency of these intestinal motility disorders in patients receiving EN and assess risk factors associated with diarrhea and constipation in hospitalized patients receiving exclusive EN therapy in a general hospital. Materials and Methods: The authors performed a sequential and observational study of 110 hospitalized adult patients fed exclusively by EN through a feeding tube. Patients were categorized according to the type of intestinal transit disorder as follows: group D (diarrhea, 3 or more watery evacuations in 24 hours), group C (constipation, less than 1 evacuation during 3 days), and group N (absence of diarrhea or constipation). All prescription drugs were recorded, and patients were analyzed according to the type and amount of medication received. The authors also investigated the presence of fiber in the enteral formula. Results: Patients classified in group C represented 70% of the study population; group D comprised 13%, and group N represented 17%. There was an association between group C and orotracheal intubation as the indication for EN (P<.001). Enteral formula without fiber was associated with constipation (logistic regression analysis: P<.001). Conclusion: Constipation is more frequent than diarrhea in patients fed exclusively by EN. Enteral diet with fiber may protect against medication-associated intestinal motility disorders. The addition of prokinetic drugs seems to be useful in preventing constipation. (Nutr Clin Pract.

Community-acquired urinary tract infection: age and gender-dependent etiology

LO, Denise Swei et al. Community-acquired urinary tract infection: age and gender-dependent etiology. J. Bras. Nefrol. [online]. 2013, vol.35, n.2, pp. 93-98. ISSN 0101-2800. http://dx.doi.org/10.5935/0101-2800.20130016. INTRODUCTION: Choosing the antimicrobial agent for initial therapy of urinary tract infection (UTI) is usually empirical and should consider the prevalence of uropathogens in different age groups and gender. OBJECTIVE: To establish prevalence rates of uropathogens in community-acquired UTI in relation to age and gender. METHODS: Crosssectional study conducted in the emergency department (ED) of a general hospital, from January to December, 2010, in patients younger than 15 years old who had clinical suspicion of UTI and collected quantitative urine culture. UTI was defined as urine culture with growth of a single agent > 100.000 colony forming units (cfu)/mL in a midstream collection or > 50.000 cfu/mL in urethral catheterization. RESULTS: There were 63.464 visits to ED. 2577 urine cultures were obtained, of whom 291 were positive for UTI (prevalence = 11.3% of clinical suspicion and 0.46% of visits), 212 cases (72.8%) in females, median age = 2.6 years. The predominant uropathogen was E. coli (76.6%), followed by Proteus mirabilis (10.3%) and Staphylococcus saprophyticus (4.1%). Among infants < 3 months, prevalence rates of E. coli were significantly lower (50% vs 78.4%; OR = 0.276; p = 0.006). Higher prevalences of Staphylococcus saprophyticus occurred among patients > 10 years (24.4% vs 0.4%; OR = 79.265; p < 0.0001). Proteus mirabilis was significantly more prevalent in boys than girls (24.0% vs 5.2%; OR = 5.786; p < 0.001). CONCLUSIONS: E. coli was the most prevalent community-acquired uropathogen. Nevertheless, initial empiric antimicrobial treatment of UTI should consider the significant prevalence of other agents different from E. coli in infants < 3 months, the high prevalence of Staphylococcus saprophyticus in patients > 10 years and Proteus mirabilis in males.

Eficácia e segurança da vacina brasileira contra hepatite B em recém-nascidos

OBJETIVO: Analisar a efi cácia e segurança de vacina recombinante contra hepatite B em recém-nascidos. MÉTODOS: O estudo foi conduzido em hospital geral do município de Guarulhos, SP, entre 2002 e 2005. A vacina recombinante contra hepatite B do Instituto Butantan (VrHB-IB) foi analisada em dois ensaios clínicos. Em ambos os ensaios, os recém-nascidos foram alocados aleatoriamente ao grupo experimental ou controle (vacina de referência). Os recém-nascidos receberam três doses das vacinas, uma em até 24 h após o nascimento e as subseqüentes 30 e 180 dias após. No primeiro ensaio 538 recém-nascidos completaram o protocolo e no segundo ensaio, 486. Considerou-se critério de equivalência a diferença na soroproteção inferior a 5%. RESULTADOS: A soroproteção no primeiro ensaio (anti HBs ≥ 10mUI/ml) foi de 92,5% (247/267) no grupo experimental, comparada a 98,5% (267/271) no grupo controle (p = 0,001). Com este resultado, a VrHB-IB não atingiu o critério de equivalência estabelecido. Após o aumento da concentração de antígeno na vacina para 25μg, a soroproteção no segundo ensaio foi de 100% no grupo experimental e 99,2% no grupo controle. Nenhum evento adverso grave foi registrado. CONCLUSÕES: A vacina VrHB-IB modifi cada foi considerada equivalente à vacina de referência e seu uso recomendado à vacinação de recém-nascidos.

Trasmissione post-natale del citomegalovirus attraverso il latte materno al neonato VLBW

Introduction Postnatal human cytomegalovirus (CMV) infection is usually asymptomatic in term babies, while preterm infants are more susceptible to symptomatic CMV infection. Breastfeeding plays a dominant role in the epidemiology of transmission of postnatal CMV infection, but the risk factors of symptomatic CMV infection in preterm infants are unknown. Patients and Methods Between December 2003 and August 2006, eighty Very Low Birth Weight (VLBW) preterm infants (gestational age ≤ 32 weeks and birth weight < 1500 g), admitted to the Neonatal Intensive Care Unit of St Orsola-Malpighi General Hospital, Bologna were recruited. All of them were breastfed for at least one month. During the first week of life, serological test for CMV was performed on maternal blood. Furthermore, urinary CMV culture was performed in all the infants in order to exclude a congenital CMV infection. Urine samples from each infant were collected and processed for CMV culture once a week. Once every 15 days a blood sample was taken from each infant to evaluate the complete blood count, the hepatic function and the C reactive protein. In addition, samples of fresh breast milk were processed weekly for CMV culture. A genetic analysis of virus variant was performed in the urine of the infected infants and in their mother’s milk to confirm the origin of infection. Results We evaluated 80 VLBW infants and their 68 mothers. Fifty-three mothers (78%) were positive for CMV IgG antibodies, and 15 (22%) were seronegative. In the seronegative group, CMV was never isolated in breast milk, and none of the 18 infants developed viruria; in the seropositive group, CMV was isolated in 21 out of 53 (40%) mother’s milk. CMV was detected in the urine samples of 9 out of 26 (35%) preterm infants, who were born from 21 virolactia positive mothers. Six of these infants had clinically asymptomatic CMV infection, while 3 showed a sepsis-like illness with bradycardia, tachypnea and repeated desaturations. Eight out of nine infants showed abnormal hematologic values. The detection of neutropenia was strictly related to CMV infection (8/9 infected infants vs 17/53 non infected infants, P<.005), such as the detection of an increase in conjugated bilirubin (3/9 infected infants vs 2/53 non infected infants, P<.05). The degree of neutropenia was not different between the two groups (infected/non infected). The use of hemoderivatives (plasma and/or IgM–enriched immunoglobulin) in order to treat a suspected/certain infection in newborn with GE< 28 ws was seen as protective against CMV infection (1/4 infected infants vs 18/20 non infected infants [GE<28 ws]; P<.05). Furthermore, bronchopulmonary dysplasia (defined both as oxygen-dependency at 30 days of life and 36 ws of postmenstrual age) correlated with symptomatic infection (3/3 symptomatic vs 0/6 asymptomatic: P<.05). Conclusion Our data suggest that CMV infection transmitted to preterm newborn through human milk is always asymptomatic when newborns are clinically stable. Otherwise, the infection can worsen a preexisting disease such as bronchopulmonary dysplasia. Human milk offers many nutritional and psychological advantages to preterm newborns: according to our data, there’s no reason to contraindicate it neither to pasteurize the milk of all the mothers of preterm infants who are CMV seropositive.

Eye-trauma: Event driven control software for gesture recognition in medical simulation

Il progetto Eye-Trauma si colloca all'interno dello sviluppo di un simulatore chirurgico per traumi alla zona oculare, sviluppato in collaborazione con Simulation Group in Boston, Harvard Medical School e Massachusetts General Hospital. Il simulatore presenta un busto in silicone fornito di moduli intercambiabili della zona oculare, per simulare diversi tipi di trauma. L'utilizzatore è chiamato ad eseguire la procedura medica di saturazione tramite degli strumenti chirurgici su cui sono installati dei sensori di forza e di apertura. I dati collezionati vengono utilizzati all'interno del software per il riconoscimento dei gesti e il controllo real-time della performance. L'algoritmo di gesture recognition, da me sviluppato, si basa sul concetto di macchine a stati; la transizione tra gli stati avviene in base agli eventi rilevati dal simulatore.
