Gruczolakorak płuca z przerzutami do przysadki mózgowej i obu nadnerczy

A case of lung adenocarcinoma with metastases in both adrenals and pituitary gland in 52-year old patient is presented. Adrenal glands metastases were diagnosed on a base of CT scans. Pituitary metastases caused gradual loss of vision. MR imaging showed a lesion in the sella and suprasellar areas and sugested meningioma. Right frontal craniotomy with the partial removal of the tumor was performed. Three days later the patient died. Histopathological results of the pituitary masses revealed adenocarcinoma

The repeated use of high dose rate brachytherapy for locally recurrent lung cancer

PurposeTo assess the effect of repeated palliative treatment with high dose rate brachytherapy in patients with advanced lung cancer.Material and MethodsFifty-six patients, 25.3% of a total of 221 patients treated for lung cancer with HDR brachytherapy were treated twice, using High Dose Rate Brachytherapy. All patients were qualified for repeated brachytherapy due to the recurrence of intrabronchial tumour and acceptable remissions after the first treatment. The survival times were compared with selected clinical data. Correlations between survival times and subjective breathing difficulties were analyzed separately.ResultsThe median survival time in the whole group of patients was 8.9 months. The period of obtaining a positive clinical response was correlated with a longer survival time (log-rank test, p=0.0009, F Cox test, p=0.007). In the multivariate analysis other statistically important prognostic factors were also included: the clinical stage of the primary tumour (F Cox test, p=0.04), and the interval between the first and second treatment (F Cox, p=0.004). None of the analyzed factors (dyspnoea, cough, haemoptysis and pain) had any influence on survival.ConclusionRepeated HDR brachytherapy in advanced lung cancer was an efficient method that in many patients led to regression of symptoms and improvement in life quality

High dose rate endobronchial brachytherapy in the management of advanced lung cancer – comparison of different doses – preliminary assessment

PurposeBrachytherapy is one of the most efficient methods of overcoming endobronchial obstruction in palliative treatment of lung cancer. In single cases, brachytherapy is performed as radical treatment, however in most of cases, due to advanced clinical stage it has a palliative aim. In the absence of clear consensus regarding the value of doses used in brachytherapy different fraction doses are used in clinical treatment. The aim of this work is to compare results of palliative high dose rate brachytherapy using various treatment protocols with the view to analysing differences in survival and diminishing breathing difficulties.Material and methodsBetween May 1999 and February 2000 at the Greatpoland Cancer Center, 69 patients with advanced lung cancer were treated by high dose rate brachytherapy. They were disqualified from radical treatment due to advanced clinical stage. The age of the patients ranged from 39 to 76 years (average 53,2 years). Fifty-one patients received a total dose of 22,5 Gy in 3 fractions once a week, 18 patients received one single fraction of 10 Gy. All the patients were divided into two groups according to their clinical stage and the Karnofsky score – those with the Karnofsky score lower than 50 were qualified for a single fraction treatment. They were under clinical and endobronchial observation as regards survival rates, local remission and subsiding dyspnoea, breathing, cough and haemoptysis in the first, third, sixth and twelveth month of observation.ResultsFour weeks after the end of treatment subjective improvement (subsidence of all symptoms) was ascertained in 61/69 (88,4%) patients. In 12 cases (17,4%) complete remission (CR), in 49 cases (71,0%) – partial remission (PR) of the tumor were found. During one year of observation 45 (65,2%) patients died, in 10 cases (14,5%) improvement of in dyspnoea was observed and in 14 cases (20,3%) recurrence and progression of the disease were noted. There was no statistical difference in the survival rates between the two groups of patients treated with different fractions protocols.Conclusions1.Brachytherapy in advanced lung cancer is an efficient method that led in most of patients to subcidence of symptoms and to improvement of the quality their lives.2.The two treatment protocols showed similar efficiency in overcoming difficulties in breathing.3.Survival rates were similar in both group of patients treated with different treatment protocols

Chemotherapy-induced peripheral neuropathy — diagnosis, evolution and treatment

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most frequent neurologic complications experienced by patients receiving antineoplastic drugs. Involvement of the peripheral nerves may have an important impact on daily activi­ties and lead to severe impairment of the patient’s quality of life (QoL). It seems to be of crucial importance to make a correct and early diagnosis of polyneuropathy and, if possible, spare the patient unnecessary suffering or loss of function. In the preceding article we have presented epidemiology, grading and pathogenesis of the toxic CIPN. The purpose of this article is to review current knowledge of diagnostic techniques, prevention and management strategies in the context of CIPN.

Original articleUsefulness of ambulatory ECG in the diagnosis of sleep-related breathing disorders

Background: Sleep-related breathing disorders (SRBD) are the additional factor related to poor prognosis in patients with cardiovascular disorders. The apnoea/hypopnoea index (AHI), describing the number of apnoea and hypopnoea episodes per one hour of sleep, has been used as a marker of severity of the disorder. The disease is present in 4% of men and 2% of women above 40 years of age. However, SRBD are diagnosed in less than 3% of patients with this syndrome due to lack of awareness of the disease among health care practitioners and patients. Polysomnography (PSG) has been used as a golden standard for detecting SRBD, however this test is available only in selected centres. Therefore, a simple, fast and inexpensive test for screening for SRBD is necessary. Respiratory activity influences the amplitude of ECG signal whereas heart rate variability (HRV) depicts the activity of the autonomic nervous system. These associations have been used to develop a new method for detection of SRBD involving analysis of HRV and morphology of ECG signal in ECG monitoring. Aim: Assessment of accuracy of SRBD detection using estimated AHI (Est.AHI), calculated from Holter ECG recordings. Methods: In a study group consisting of 74 patients tested for SRBD, simultaneous PSG and 24-hour ECG monitoring were performed. Following PSG, AHI for each patient was calculated. According to the AHI values patients were classified as SRBD patients (AHI >15), non-SRBD patients (AHIWstęp: Zaburzenia oddychania podczas snu (ZOPS) są czynnikiem obciążającym rokowanie w wielu chorobach układu sercowo-naczyniowego.

The Automatic Algorithm of the Auto-CPAP Device as a Tool for the Assessment of the Treatment Efficacy of CPAP in Patients with Moderate and Severe Obstructive Sleep Apnea Syndrome

Obstructive sleep apnea syndrome (OSAS) is a common sleep-related breathing disorder where precise treatment assessment is of high importance. We aimed to validate an automatic algorithm of the auto-CPAP device and reveal polygraph usefulness in the OSAS diagnosis and treatment of outpatients. One hundred patients with moderate OSAS, severe OSAS, and excessive daytime sleepiness qualified for CPAP treatment were included. The study was conducted in three stages. The first stage included a minimum 6-hour polysomnographic examination to select moderate and severe OSAS. The second stage involved an auto-CPAP treatment lasting at least 4 h with simultaneous polygraph recording. The third stage was a titration of at least 4 h with auto-CPAP. The Apnea–Hypopnea Index (AHI) and oxygen desaturation index (ODI) were calculated under auto-CPAP treatment, simultaneously using polygraph (stage two), and as a result of treatment with auto-CPAP (stage three). The mean AHI was 40.0 ± 20.9 for OSAS. Auto-CPAP treatment was effective in 97.5%. The mean residual AHI was 8.6 ± 4.8; there was no significant difference between the AHI CPAP, and the AHI polygraph values were assessed with an accuracy of 3.94/h. The sensitivity and specificity of calculated cut point 8.2 event/hour were: 55% and 82%, respectively. The calculated AUC for the AHI CPAP parameter was 0.633. Presented data confirmed that the automatic algorithm of auto-CPAP is a good tool for the assessment of the treatment efficacy of CPAP in patients, i.e., home setting, with a moderate or severe stage OSAS-presented high sleepiness

Dietary and cardio-metabolic risk factors in patients with Obstructive Sleep Apnea: cross-sectional study

Background Little is known about the role of dietary intake in obstructive sleep apnea (OSA), which could prove important in improving clinical outcomes for people with obesity and/or cardiovascular disease within these populations. Reduction in energy intake typically results in weight loss, markedly improving metabolic parameters and ameliorating OSA severity. The aim of this study was to evaluate the association of dietary and cardio-metabolic risk factors with OSA severity. Methods This was a cross-sectional study. A total of 75 volunteers at risk of OSA were recruited from 153 patients suffering from sleep disturbance at the Department of Pulmonology, Allergology and Respiratory Oncology at the Poznan University of Medical Sciences. Polysomnography was used for OSA diagnosis. Sleep quality was assessed by the Pittsburgh Sleep Quality Index. Blood pressure, parameters of glucose (fasting glucose, glucose tolerance test) and lipid metabolism (TC, LDL-C, HDL-C, TG) were assessed using routine enzymatic methods. Dietary intake was evaluated by 24-hr dietary recalls and Food Frequency Questionnaire. Ordinal logistic regression models were used for association of background characteristics and dietary intake with OSA severity. All analyses were adjusted for age, sex, BMI, smoking and alcohol intake. Results A higher percentage of smokers were observed in patients with mild OSA, while alcohol intake was the highest in severe OSA patients. Approximately 60% of the studied patients were self-reported poor sleepers. Results from ordinal logistic regression models showed that higher intakes of alcohol intake were associated with increased odds of severe OSA; whereas higher HDL-C levels were associated with lower odds (OR 0.01; 95% CI [0.0003–0.55]). Significantly higher odds of high OSA severity were observed in patients with disturbed sleep stages and obstructive sleep apnea. Moreover, the investigation of nutrient intake in relation to OSA severity showed that a higher intake of dietary fiber was associated with decreased OSA severity (OR 0.84; 95% CI [0.71–0.98]). Conclusions The severity of OSA is related to higher alcohol consumption and disturbed sleep. The significantly lower dietary fiber intake in patients with severe OSA is of particular importance for dietary consulting in clinical practice, which may positively influence cardiometabolic outcomes
