Ambulatory Hysteroscopy Results Post-Menopause: Comparative Study Between Patients With and Without Metrorrhagia

Our objective was to compare the results of ambulatory hysteroscopy in postmenopausal women with and without uterine bleeding. A retrospective descriptive study was carried out on 236 women who were at least 2 years into the menopause, who were not undergoing hormone treatment and who had had abnormal pelvic ultrasound results. Of these women, 150 were asymptomatic and 86 reported haemorrhage. Diagnostic and operative outpatient hysteroscopy was performed between January 2002 and December 2003. There was no difference between the two groups regarding age of patients, age of menopause and presence of at least one of the risk factors for endometrial carcinoma evaluated, although obesity was more frequent in the symptomatic group. Abnormal ultrasound results for these women corresponded in the majority of cases to intracavitary disease, and the absence of organic endometrial pathology was 9.3% vs 11.3% in each group. The more frequent pathology was benign endometrial polyps (64% in bleeding patients and 84.7% in asymptomatic ones). Endometrial carcinoma was diagnosed in 23.3% of women with metrorrhagia and in 1.3% of asymptomatic women. We diagnosed 2.6% of malignancy inside polyps. Hysteroscopy results were confirmed by histology in 90.3% of cases. See and treat in one session was achieved in 91% of benign endometrial polyps. Ambulatory hysteroscopy has high sensitivity and specificity for intracavitary pathology and high tolerability and safety. See and treat in one session can be achieved in the majority of lesions with indication for excision. These results make us advise our menopausal patients with abnormal uterine bleeding to undergo diagnostic hysteroscopy complemented with biopsy.

The Oncological and Functional Risks of the Organ Preservation Experimental Treatment Approach

We increasingly face conservative surgery for rectal cancer and even the so called ‘wait and see’ approach, as far as 10–20% patients can reach a complete pathological response at the time of surgery. But what can we say to our patients about risks? Standard surgery with mesorectal excision gives a <2% local recurrence with a post operative death rate of 2–8% (may reach 30% at 6 months in those over 85), but low AR has some deterioration in bowel function and in low cancer a permanent stoma may be required. Also a long-term impact on urinary and sexual function is possible. Distant metastasis rate seem to be identical in the standard and conservative approach. It is difficult to evaluate conservative approach because a not clear standardization of surgery for low rectal cancer. Rullier et al tried to clarify, and they found identical results for recurrence (5–9%), disease free survival (70%) at 5y for coloanal anastomosis and intersphinteric resection. Other series have found local recurrence higher than with standard approach and functional results may be worse and, in some situations, salvage therapy is compromised or has more complications. In this context, functional outcomes are very important but most studies are incomplete in measuring bowel function in the context of conservative approach. In 2005 Temple et al made a survey of 122/184 patient after sphinter preserving surgery and found a 96.9% of incomplete evacuation, 94.4% clustering, 93.2% food affecting frequency, 91.8% gas incontinence and proposed a systematic evaluation with a specific questionnaire. In which concerns ‘Wait and see’ approach for complete clinical responders, it was first advocated by Habr Gama for tumors up to 7cm, with a low locoregional failure of 4.6%, 5y overall survival 96%, 72% for disease free survival; one fifth of patients failed in the first year; a Dutch trial had identical results but others had worse recurrence rates; in other series 25% of patients could not be salvaged even with APR; 30% have subsequent metastatic disease what seems equal for ‘wait and see’ and operated patients. In a recent review Glynne Jones considers that all the evaluated ‘wait and see’ studies are heterogeneous in staging, inclusion criteria, design and follow up after chemoradiation and that there is the suggestion that patients who progress while under observation fare worse than those resected. He proposes long-term observational studies with more uniform inclusion criteria. We are now facing a moment where we may be more aggressive in early cancer and neoadjuvant treatment to be more conservative in the subsequent treatment but we need a better stratification of patients, better evaluation of results and more clear prognostic markers.

Lesões Inalatórias no Doente Queimado

Inhalation injuries are currently the factor most responsible for mortality in thermally injured patients. Inhalation injuries may occur independently, but generally occur together with skin burn. Smoke inhalation affects all levels of the respiratory system and the extent of the inhalation injury depends on the duration, exposure, amount and toxicity of the fume temperature, concentration and solubility of toxic gases, the occurrence of the accident in a closed space and pre-existing diseases. Smoke inhalation also induces changes in the systemic organs with the need for more fluid for resuscitation. Systemic vasoconstriction, with an elevation in systemic vascular resistance, a fall in myocardial contractility and a great increase in lymphatic flow in soft tissue are the most important changes in systemic organs. On admission of a burn patient there is a high suspicion of inhalation injury when there are signs and symptoms such as hoarseness, strides, dyspnea, carbonaceous sputum, anxiety or disorientation, with or without face burns. The patient with these findings has partial airway obstruction and there is substantial risk complete airway obstruction occurring of secondary to the edema. Patients with suspected inhalation injury should be intubated so as to maintain airway patency and avoid a total obstruction. This group of patients frequently develop respiratory failure with the need for mechanical ventilatory support. Nosocomial infections, sepsis and multiple organ system failure may occur. Late complications of inhalation injury are tracheitis, tracheal stenosis or tracheomalacia and chronic airway disease, which is relatively rare. Early diagnosis of inhalation injury and treatment in a Burn Unit by a group of highly motivated clinicians and a good team of nurses is essential in order to decrease the morbidity and mortality related to inhalation injury.

Clinical and Bacteriological Survey of Diabetic Foot Infections in Lisbon

AIMS: An epidemiological survey of diabetic foot infections (DFIs) in Lisbon, stratifying the bacterial profile based on patient demographical data, diabetic foot characteristics (PEDIS classification), ulcer duration and antibiotic therapy. METHODS: A transversal observational multicenter study, with clinical data collection using a structured questionnaire and microbiological products (aspirates, biopsies or swabs collected using the Levine method) of clinically infected foot ulcers of patients with diabetes mellitus (DM). RESULTS: Forty-nine hospitalized and ambulatory patients were enrolled in this study, and 147 microbial isolates were cultured. Staphylococcus was the main genus identified, and methicillin-resistant Staphylococcus aureus (MRSA) was present in 24.5% of total cases. In the clinical samples collected from patients undergoing antibiotic therapy, 93% of the antibiotic regimens were considered inadequate based on the antibiotic susceptibility test results. The average duration of an ulcer with any isolated multi-drug resistant (MDR) organism was 29 days, and previous treatment with fluoroquinolones was statistically associated with multi-drug resistance. CONCLUSIONS: Staphylococcus aureus was the most common cause of DFIs in our area. Prevalence and precocity of MDR organisms, namely MRSA, were high and were probably related to previous indiscriminate antibiotic use. Clinicians should avoid fluoroquinolones and more frequently consider the use of empirical anti-MRSA therapy.

A Brother or a Sister With CP. How Much it Makes a Difference in Childhood and Adulthood?

Every month we see to be published dozens of scientific papers about etiology and physiopathology of CP, imaging, treatment, survival, quality of life of patients and of mothers (just a few) and so on. Papers dealing with the feelings and the problems of siblings of children and adults with CP in the most important scientific journals are extremely rare. However in internet we can find the sites of the most important Cerebral Palsy Societies, like the British, the Australian and the American ones already devoting a special attention to the issue of siblings; we also can see several interesting blogs of parents sharing their experiences not only with the handicapped child but also with the siblings, even counseling some books written for children giving practical advices how to deal and live with a handicapped sibling. What was a surprise to me were the several sites of adults having a disabled sibling, frequently with CP, in a new situation: without parents to care them.

Onychomycosis in Patients with Chronic Leg Ulcer and Toenail Abnormalities

Nails have a limited number of reactive patterns to disease. Accordingly, toenail changes of different etiologies may mimic onychomycosis. OBJECTIVE To determine the prevalence of toenail onychomycosis among patients with leg ulcer and toenail abnormalities attending a dermatology clinic. METHODS A cross-sectional study was conducted through the analysis of clinical records and results of mycological examination. RESULTS A total of 81 patients were included, with a median age of 76.0 years. Most ulcers were of venous etiology, followed by those of mixed and arterial pathogenesis. The mycological evaluation confirmed the diagnosis of onychomycosis in 27.2% of the patients. The etiologic agent was a dermatophyte in 59.1% of isolates in nail samples, while Trichophyton interdigitale was the most frequent fungal species (40.9%). CONCLUSIONS Most toenail abnormalities in patients with chronic leg ulcer were not onychomycosis. This study highlights the importance of systematic mycological examination in these patients, in order to avoid overtreatment with systemic antifungals, unnecessary costs and side effects.
