Associations between gut microbiota characteristics and non-motor symptoms following pharmacological and surgical treatments in Parkinson's disease patients.

BACKGROUND: The gut microbiota has been implicated in Parkinson's disease (PD), with alterations observed in microbial composition and reduced microbial species richness, which may influence gastrointestinal symptoms in PD patients. It remains to be determined whether the severity of gastrointestinal symptoms correlates with microbiota variations in PD patients treated pharmacologically or with subthalamic nucleus deep brain stimulation (STN-DBS) therapy. This study aims to explore how these treatments affect gut microbiota and gastrointestinal symptoms in PD, identifying specific microbial differences associated with each treatment modality. METHODS: A total of 42 individuals diagnosed with PD, along with 38 age-matched household control participants, contributed stool samples for microbiota characterization. Differences in the gut microbiota across various groups of PD patients and their households were identified through comprehensive sequencing of the 16S rRNA gene amplicon sequencing. KEY RESULTS: Differences in microbial communities were observed between PD patients and controls, as well as between PD patients receiving pharmacological treatment and those with STN-DBS. Pharmacologically treated advanced PD patients have higher gastrointestinal dysfunctions. Gut microbiota profile linked to STN-DBS and reduced levodopa consumption, characterized by its anti-inflammatory properties, might play a role in diminishing gastrointestinal dysfunction relative to only pharmacological treatments. CONCLUSIONS & INFERENCES: Advanced PD patients on medication exhibit more gastrointestinal issues, despite relatively stable microbial diversity, indicating a complex interaction between gut microbiota, PD progression, and treatment effects. An imbalanced gut-brain axis, particularly due to reduced butyrate production, may lead to constipation by affecting the enteric nervous system, which emphasizes the need to incorporate gut microbiome insights into treatment strategies.

Rotavirus Vaccination of Premature Newborns in the NICU: Evaluation of Vaccination Rates and Safety Based on a Single-Centre Study.

Preterm newborns are babies born before the end of the 36th week of gestational life. They are at increased risk of infection and death from infectious diseases. This is due, among other things, to the immaturity of the immune system and the long hospitalisation period. One common infectious disease in the paediatric population is rotavirus (RV) infection. We now have specific vaccines against this pathogen. The aim of this study was to evaluate the safety of rotavirus vaccination in the neonatal intensive care unit (NICU) setting and to determine the tolerance of this vaccine in low- and extremely low-weight children. The study carried out at a single centre, the University Hospital in Kraków, also allowed the assessment of vaccination trends during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. During the observation period, 126 premature newborns received the RV vaccine. We observed no adverse effects, and our analysis shows safety and good tolerance of the vaccine among preterm babies. In addition, we observed an increase in vaccination rates between 2019 and 2021, partly explained by parents' anxiety about infectious diseases in the era of pandemics and partly explained by a change in vaccination policy in Poland and the introduction of refunding for RV vaccination.

Histopathological pulmonary findings of survivors and autopsy COVID-19 cases: A bi-center study.

The coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), evolved into a global pandemic. As ACE2 on the surface of alveolar cells of the lung epithelium is one of the potential target receptors for SARS-CoV-2, the respiratory symptoms are the most common presentation of COVID-19. The aim of our study was to investigate the morphological findings in lung tissue after being infected by SARS-CoV-2 and compare histopathologic changes in patients with COVID-19 infection history who died to those who survived. We analyzed lung tissue samples from 9 patients who died from COVID-19 and from 35 patients with COVID-19 infection history who survived and had undergone lung surgery for different reasons. Most of histopathological changes in autopsy and survivors' cases overlapped; however, they occurred with different frequency. The predominant histologic finding both in the case of the deceased and the survivors was patchy distribution of foamy macrophages in the alveolar spaces. In comparison with autopsy cases viral cytopathic-like changes in hyperplastic pneumocytes were rarely observed in the survivors' lung tissue. Pulmonary edema, fibrin deposition within alveoli, bronchopneumonia, small vessel thrombosis and type II pneumocyte hyperplasia were also more often observed within autopsy cases. Life-threatening complications such as hyaline membrane formations and diffuse alveolar damage were present only within the deceased, whereas changes requiring enough time to progress to the fibrotic phase, such as organizing pneumonia, bronchiolization of the alveoli, and interstitial fibrosis were observed in the lung parenchyma only in survivors. Additionally, 14 cases of pulmonary pneumo-hematocele in patients with COVID-19 infection history who survived were observed. It is a newly observed entity in the form of a cystic lesion formed by large accumulation of blood and fibrin between the collapsed and rejected lung parenchyma and/or present with air-fluid levels. The thin wall of pneumo-hematocele is formed by the inter lobar interstitial fibroconnective tissue and has no epithelial lining or bronchial wall elements. As the COVID-19 pandemic continues, new complications following SARS-CoV-2 infection are identified. Newly observed entity in patients with COVID-19 infection history who survived is pulmonary pneumo-hematocele. The appearance of these lesion has become increasingly frequent.

A network meta-analysis on the comparative effect of nutraceuticals on lipid profile in adults.

It is estimated that 2.6 million deaths worldwide can be attributed to hypercholesterolemia. The main reason for non-adherence to statin therapy are the statin-associated muscle symptoms (including nocebo/drucebo effect). In this case, apart from ezetimibe, nutraceuticals are prescribed. We aimed to assess the comparative efficacy of different nutraceuticals in terms of lowering low density lipoprotein cholesterol (LDL-C) and improving lipid profile. Electronic and hand searches were performed until February 2021. The inclusion criteria were the following: (1) randomized trial with any of the reportedly LDL-C lowering nutraceutical: artichoke, berberine, bergamot, garlic, green tea extract, plant sterols/stanols, policosanols, red yeast rice (RYR), silymarin or spirulina. (2) outcome either LDL-C (primary outcome), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) or serum triglycerides (TG). Random effects network meta-analysis (NMA) was performed to rank the effect of each intervention using frequentist approach. Finally, a total of 131 trials enrolling 13,062 participants were included. All analysed nutraceuticals except for policosanols were more effective in lowering LDL-C (-1.21 [-46.8 mg/dL] to -0.17 [-6.6 mg/dL] mmol/l reduction) and TC (-1.75 [-67.7 mg/dL] to -0.18 [7 mg/dL] mmol/l reduction) than placebo/no intervention. The most effective approaches in terms of LDL-C- and TC-lowering were bergamot and RYR (-1.21 [-46.8 mg/dl] and -0.94 [-36.4 mg/dl] mmol/l) reduction respectively. In conclusion, bergamot and RYR appear to be the most effective nutraceuticals in terms of LDL-C and TC reduction. Evidence for bergamot effect was based on relatively small study group and may require further investigations. Policosanols have no effect on the lipid profile.

Near-Term Cerebroplacental Doppler, Heart Morphology, and Neonatal Biometry in Hypoplastic Left Heart Syndrome.

OBJECTIVES: To analyze near-term cerebroplacental Doppler, heart morphology, and neonatal biometry in isolated hypoplastic left heart syndrome (HLHS) relative to healthy controls. METHODS: This retrospective study included 55 fetuses with HLHS (29 with mitral valve stenosis [MS]/aortic valve atresia [AA], 14 with MS/aortic valve stenosis, and 12 with mitral valve atresia [MA]/[AA]) diagnosed prenatally between 2010 and 2019 at 2 referral centers and 101 healthy controls. Ultrasound assessment included umbilical artery (UA), middle cerebral artery (MCA) pulsatility index (PI), and cerebroplacental ratio (CPR), with neonatal weight, length, head circumference (HC), Apgar score, and UA pH measured at birth. RESULTS: In total, 32.7% of HLHS fetuses had abnormal MCA-PI and UA-PI, and 38.2% had CPRs below the fifth percentile before birth. All tested Doppler parameters differed from those of the healthy controls (P ≤ .01). Birth weight and length were comparable between HLHS and control fetuses, whereas birth HCs were smaller in the HLHS group than in the control group (P = .018). In both groups, increased UA-PI correlated with lower birth weight, but only HLHS fetuses with UA-PI > the 95th percentile had a lower median HC at birth than those with normal UA-PI (P = .045). The median UA-PI percentile was higher in fetuses with MA than in fetuses with MS (P = .015). The ascending aortic diameter correlated with birth weight (P = .036) and birth length (P = .039). CONCLUSION: Abnormal cerebroplacental hemodynamics are evident in a high percentage of near-term fetuses with HLHS, and increased placental resistance may contribute to birth weight and HC. Moreover, heart morphology may impact placental circulation and neonatal biometry.

Neglected workforce: pharmacists and their health-related quality of life.

BACKGROUND: pharmacists remain on the frontline of public health around the globe and their performance directly impacts patients' safety. So far, to our knowledge, no European study has been dedicated to their heath-related quality of life (HQoL). Therefore, the primarily aim of our study was to evaluate HQoL of Polish pharmacists utilizing the SF-36 health survey with regard to anthropometric and lifestyle-related variables. METHODS: A total sample screened consisted of 1412 respondents, yet 765 pharmacists (mean age 40, 86.3% females) finally participated in the study. HQoL was assessed with the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36). RESULTS: The lowest median scores were noted for general health (GH, 50.0) and vitality (V, 60.0) domains. No gender differences regarding physical and mental summary scores were found. Significant difference of HQoL was found among the assessed age groups in several domains, especially physical functioning (PF) and GH (p <0.001) scores, and especially in the group of 51-60-year-old-respondents. Correlations were found between PF (r = -0.29, p <0.001), GH (r = -0.25, p <0.001) and age as well PF (r = -0.27, p <0.001), GH (r = -0.21, p <0.001) and BMI. Self-assessed dietary habits were correlated with PF (r = 0.22, p <0.001), mental health (r = 0.25, p <0.001), GH (r = 0.27, p <0.001) and V (r = 0.30, p <0.001) scores. CONCLUSIONS: The analysis indicates that pharmacists tend to have similar mental and physical burden according to SF-36, with age, BMI and dietary habits as predominant factors influencing their HQoL. The study presents unique values for future comparative analyses related, for instance, to the influence of the ongoing pandemic on HQoL of health-care providers.

Hypoplastic left heart syndrome: from the prenatal to the postnatal period.

OBJECTIVES: To analyse a population of foetuses with prenatally diagnosed hypoplastic left heart syndrome (HLHS). MATERIAL AND METHODS: Retrospective study of foetuses diagnosed with HLHS between 2013 and 2017 in a referral centre. RESULTS: HLHS was found in 9.7% (65/665) of foetuses with cardiovascular abnormalities (CVA). As an isolated anomaly, HLHS was present in 40% of cases; in 24.5% other CVA were detected; in 14%, CVA and extracardiac anomalies; and in 21.5% only extracardiac malformations. Genetic disorders were present in 18.4% (12/65) of foetuses. 42% of cardiovascular and 25% of extracardiac anomalies were diagnosed postnatally. There were 10 (15.4%) elective terminations, 1 (1.5%) spontaneous foetal demise. Two newborns died after birth before surgery. Of the 52 children who underwent Norwood surgery, 13 (25%) died (9 with additional anomalies, and 4 with isolated HLHS). Of the 38 children who underwent stage II surgery, 2 (5.2%) with isolated HLHS died, and 1 (2.6%) with CVA. CONCLUSIONS: A diagnosis of HLHS is an indication for a detailed examination of cardiac and noncardiac structures. It is advisable to consider genetic testing, together with the microarray assessment. The prognosis depends on underlying cardiac and extracardiac anomalies and coexisting genetic defects.

Assessments of plasma acyl-ghrelin levels in Parkinson's disease patients treated with deep brain stimulation.

Gastrointestinal dysfunction is the most common non-motor symptom in Parkinson's disease (PD) with rates rising as the disease progresses. Deep brain stimulation of subthalamic nucleus (STN DBS) improves motor functions in advanced PD. However, the effect of STN DBS on ghrelin concentration and consequently on motility disturbances as well as body weight is unclear. The objective of this study was to assess acyl-ghrelin levels in comparison to weight in advanced PD patients treated with STN DBS. Plasma concentrations of acyl-ghrelin was measured in 29 PD patients in the fasting state and at 30, 60, 120, and 180 min after a standard meal preoperatively and 3 months after surgery. The level of acyl-ghrelin in PD patients were compared with 30 age and sex-matched healthy controls. We reported that mean plasma acyl-ghrelin levels were decreased in PD patients before STN DBS in fasting (p = 0.0003) and in 30 min postprandial phase (p = 0.04) compared with healthy controls. The plasma acyl-ghrelin levels after STN DBS increased in pre-prandial and postprandial phase in PD patients at the investigated time points. Body weight gained on average 2.33 kg during the first 3 months after surgery. There was no correlation between the acyl-ghrelin plasma levels and BMI. After STN DBS in fasting and postprandial phase plasma acyl-ghrelin levels were increased. The results showed that STN DBS therapy elicited a modification of ghrelin levels, increasing its concentration in pre- and postprandial state. In addition, body weight was increased during 3 months after surgery.

Activities of Daily Living and Their Relationship to Health-Related Quality of Life in Patients with Parkinson Disease After Subthalamic Nucleus Deep Brain Stimulation.

BACKGROUND: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) can reduce motor symptoms in patients with Parkinson disease (PD) and improve their health-related quality of life (HRQoL). The effect of STN DBS on activities of daily living (ADL), an important component of quality of life, is poorly understood. We aimed to investigate effects of STN DBS on HRQoL and ADL in patients with PD. METHODS: HRQoL and ADL were assessed using the following disease-specific and generic questionnaires at baseline and 3, 6, and 12 months after surgery: the Parkinson's Disease Questionnaire 39 (PDQ-39), the Short-Form 36 health survey questionnaire, the World Health Organization Quality of Life Scale-Brief version, the Unified Parkinson's Disease Rating Scale part II, the ADL scale, and the Instrumental Activities of Daily Living scale. RESULTS: We reported significant early improvements (3 months) in the HRQoL and ADL, and these benefits increased over time (6 months); however, further improvement between 6 and 12 months was nonsignificant. Two PDQ-39 subdomains (social support and communications) and a Short-Form 36 health survey questionnaire subdomain (social functioning) showed declines after surgery. Changes in the Instrumental Activities of Daily Living scale were significantly correlated with changes in the PDQ-39 summary index and other PDQ-39 subdomains, including mobility, emotional well-being, social support, and cognition, at all follow-up points. CONCLUSIONS: STN DBS caused a marked improvement in HRQoL at 3 and 6 months; however, HRQoL remained stable at the 12-month postoperative follow-up. Moreover, we have shown a significant correlation between ADL performance and HRQoL after STN DBS.

Is the "farm effect" hypothesis still current? Atopy and allergic diseases in rural and urban children in Poland.

OBJECTIVE: The prevalence of allergic diseases has reached epidemic proportions in the Western world. Although farm-living has been associated with a lower prevalence of asthma and atopy, a marked increase in atopy among rural populations after accession to the European Union has been recently reported in Poland. Here, we aimed to investigate the effect of living environment on the prevalence of atopy and allergic diseases in Polish children. METHODS: 400 schoolchildren aged 10-14 years from the capital city (223) and from traditional rural part of the country (177) were recruited from June to November 2011. Data on allergic diseases and symptoms were collected by means of questionnaire and physical examination. Atopy was assessed based on skin prick tests (SPTs) reactivity to inhalant allergens in 350 children. RESULTS: A high discrepancy between the prevalence of allergic symptoms (46.7%) and doctor-diagnosed allergic diseases (25%) was demonstrated (p < 0.0001). Urban children had a higher overall prevalence of allergic diseases and atopy than children living in rural areas, 29.3% versus 17.1% (p = 0.007) and 33.5% versus 20% (p = 0.0045), respectively. However, no significant differences in the rates of particular allergic diseases were noted (p > 0.05). There was higher SPT positivity to trees, grass, corn, weeds, animal dander, and molds in urban children (p < 0.05). CONCLUSIONS: Our data support the protective effect of farm-living on the prevalence of atopy and overall allergic diseases, albeit not on particular allergic diseases, in children in Poland. The underlying mechanisms are not identified, but current socioeconomic changes may be responsible.

Feasibility and normal values of an integrated conductivity (Nanoduct™) sweat test system in healthy newborns.

BACKGROUND: Nanoduct™ is a simple and practical sweat analysis system measuring conductivity in situ. It requires only three microlitres of sweat, making it especially applicable to newborns. METHODS: We measured conductivity in 260 healthy term infants at the age of four days, and again at four weeks to determine the proportion of successful tests, test duration, and normal values for sweat conductivity in newborns. RESULTS: Sufficient sweat was collected in 159/260 of four-day olds (61%), and in 225/239 of four-week olds (94%). Mean (sd) test duration was 27 (5) and 25 (5) min. Mean (sd, range) conductivity was 53mmol/l (16, 8-114) at age four days, and 36 (9, 12-64) at four weeks. CONCLUSIONS: Determination of sweat conductivity using Nanoduct™ cannot be recommended for four-day old newborns. However, at the age of four weeks the success rate is high (94%), and conductivity values at that age are comparable to older healthy children.

The effect of subthalamic deep brain stimulation on gastric motility in Parkinson's disease.

OBJECTIVE: Deep brain stimulation of the subthalamic nucleus (STN-DBS) is well established for treating the motor symptoms for advanced Parkinson's disease (PD) but its effects on gastric myoelectrical activity and gastrointestinal symptoms have not been well studied. The aim of this study was to evaluate the effect of STN-DBS on gastric motility using electrogastrography (EGG). METHODS: Twenty patients with PD (5 females, 15 males; mean aged 58.0 ± 9.0 years) who underwent STN-DBS were studied. EGG was performed in fasting and postprandial conditions before STN-DBS and 3 months after the surgery. We also evaluated the frequency and severity of gastrointestinal symptoms based on a structured gastrointestinal dysfunction questionnaire. RESULTS: After STN-DBS the percentage of normogastria (47.8 ± 20.7 vs 51.3 ± 15.1) and period dominant power (PDP) (11.8 ± 1.2 vs 12.3 ± 0.9) significantly increased, the percentage of arrhythmia decreased compared to the baseline during fasting and postprandial state. Abnormal response to a meal (power ratio of PDP <1 after meal) decreased from 70% to 55% after 3 months follow-up. The abnormal EGG (the percentage of normogastria <70%) decreased in both fasting (from 80% to 65% patients) and postprandial state (from 80% to 60% patients), respectively after the surgery. The most common GI symptoms reported prior to the surgery were constipation 95%, difficulty with defecation 85% and dysphagia 50%. After STN-DBS all gastrointestinal symptoms improved, the greatest improvement was observed in difficulty with defecation. CONCLUSION: Our results suggest that STN-DBS improves gastric motility as well as gastrointestinal symptoms in PD. Further studies of gastrointestinal motility in PD are warranted.

[The diagnosis of latent tuberculosis infection in children in XXI century. Is tuberculin skin test still up to date?]. / Wspólczesna diagnostyka zakazenia pratkiem gruzlicy u dzieci ­ czy nadal odczyn tuberkulinowy?

Tuberculosis morbidity rates in Poland have been gradually decreasing. Nevertheless, there are approximately 8 thousand cases being registered annually, which includes almost 3 thousand massively infectious patients. In the last 3 years, around 100 cases/year have been reported among children below 14 years of age. Infection with Mycobacterium tuberculosis should be considered in all patients who present symptoms suggesting tuberculosis, have had recent contact with a person suffering from lung tuberculosis or are planned to undergo an immunosuppressive treatment. HIV infected patients are also supposed to have screening tests for M. tuberculosis infection performed. For over a 100 years tuberculin skin test (TST) was the only test capable of confirming tuberculous infection. TST is based on the assessment of skin reaction to intracutaneous injection of tuberculin. Due to cross-reaction to the injected tuberculin in BCG vaccinated individuals, the correct interpretation of the test is difficult. Since 13 years new immunological assays have been available. They are based on detecting interferon gamma (Interferon Gamma Release Assay - IGRA) concentration in blood serum, which has previously been incubated with Mycobacterium tuberculosis antigens absent in the BCG strain. In infected individuals interferon gamma is intensively produced by memory cells in reaction to the contact with previously met Mycobacterium antigens. Many trials have proved IGRA's high sensitivity and, higher than TST, specificity. Recent guidelines promote the usage of IGRAs, even in children.

[Is computed tomography scanning necessary in every case of minor head trauma? Clinical and tomographic analysis of a cohort of patients]. / Czy badanie tomografii komputerowej jest konieczne w kazdym przypadku lekkiego urazu glowy? Analiza materiatu klinicznego i radiologicznego grupy chorych.

INTRODUCTION: The objective of the study was an assessment of the occurrence of traumatic cerebral lesions and skull fractures in patients with mild head trauma. A total of 171 patients' notes, 89 male (52%) and 82 female (48%), mean age 48 years, were subjected to analysis. RESULTS: Of the 171 patients, in 58 (34%) CT scanning of the head was not performed for various reasons, and these patients were discharged home. Of the remaining 113 persons, who had head CT performed, in 99 (88%) no abnormalities were found; in 10 (9%) CT scans revealed pathological findings unrelated to the trauma: most frequently cortical-subcortical atrophy followed by old post-stroke foci, and in 4 patients (3%) post-traumatic pathologies: skull fractures in 2 and facial bone fractures in 2. Diagnosis of these fractures did not change the conservative treatment of these patients, but only prolonged in-patient stay for 2-3 days. All skull and facial bone fractures occurred in patients who were alcohol intoxicated, were lying, could not maintain vertical position, or who had the "racoon eyes" sign. CONCLUSIONS: The results of our study show that lack of abnormalities in neurological examination in patients after mild head injury is a reliable indicator for omitting CT scanning, because the risk of overlooking brain injuries in these patients is minimal. However, patients who are intoxicated, have problems with maintaining a vertical position and have the "racoon eyes" sign, are likely to have skull or facial fractures, and CT scanning is therefore justified. Considering these precursors (guidelines) and the use of clinical decision rules described in the article may reduce the number of head CT scans performed "just in a case".

Statistical and histological analysis of tumors of the upper extremity.

BACKGROUND: Tumors of the upper extremity are common and usually benign. The most commonly diagnosed are ganglion cysts: specific, non-neoplastic swellings localized mostly around the wrist. OBJECTIVE: The objective of this retrospective study was to determine the proportion of various types of nonganglionic hand tumors operated on at the authors' institution in 2014. METHODS: A total of 246 patients, 141 women (57 %) and 105 men (43 %), with a mean age of 53 years and with tumorsof the upper extremity, were identified and treated in the authors' institution in 2014. RESULTS: Almost half of the lesions were localized in the fingers (n = 119, 48 %), followed by the wrist (n=49, 20 %), metacarpus (n = 40, 16 %), and more proximal parts (n = 38, 16 %). The time between the patients noticing the lesion and surgery was a mean of 4 years (range, 1 month to 30 years). The most common lesion was giant cell tumor of the tendon sheath (n = 58, 23 %), followed by lipoma (n = 40, 16 %), epidermal cyst (n = 23, 9 %), enchondroma (n=16, 6 %), hemangioma (n = 14, 6 %), fibroma (n = 11, (4 %), glomus tumor (n = 10, (4 %), and rheumatoid nodule (n = 10, (4 %). Two cases of malignant fibrosarcoma were identified incidentally. CONCLUSION: A brief review of the literature is made referring to the data presented here.

[Evaluation of heart rate and blood pressure variability in Parkinson's disease patients after bilateral subthalamic deep brain stimulation]. / Ocena zmiennosci rytmu serca i cisnienia tetniczego u osób z choroba Parkinsona po obustronnej glebokiej stymulacji jadra niskowzgórzowego.

INTRODUCTION: Autonomic dysfunctions are the most common non-motor symptoms of Parkinson's disease (PD) and often precede the motor symptoms of the disease. Autonomic dysfunction may be a dominant symptom of the advanced stages of PD as well as a major cause of patient disability. Despite the wide use of neurostimulation in clinical practice, the effect of deep brain stimulation of subthalamic nucleus (STN DBS) on autonomic symptoms of PD still remains only partially understood. The aim of the study is evaluation of heart rate variability (HRV) and blood pressure variability (BPV) in patients with PD before STN DBS and following bilateral STN DBS. MATERIAL AND METHODS: The study included 25 subjects aged between 31 and 71 years, diagnosed with the idiopathic PD and selected for treatment with STN DBS. All the patients were in advanced stages of PD, disease duration ranged from 5 to 22 years. The patients enrolled into this study underwent STN DBS. Neurological examination including assessment of the severity of parkinsonism according to UPDRS scale, a psychological examination and an electrophysiological examination of autonomic disturbances based on heart rate and blood pressure variability were conducted on all patients two weeks before and three months after STN DBS. RESULTS: After STN DBS an improvement in terms of the analyzed parts of the UPDRS has been shown. The improvement of motor disorders assessed by III part UPDRS during the "off" medication/stimulation "on" was 67.8%. Orthostatic hypotension before the STN DBS procedure was observed in 56% of patients and after STN DBS in 53% of them. Before STN DBS the imbalance of the sympathetic--parasympathetic components with the predominance of the sympathetic based on HRV parameters--the ratio LF/HF-RRI (2.5) and a higher rate of LFnu (61.3%) than HFnu (38.6%) has been shown. Three months post STN DBS an increase parameters of spectral analysis of HRV in the low frequency LF-RRI, and high-frequency HF-RRI and the total power spectrum PSD-RRI was observed. After STN DBS an increase of parameters of spectral analysis of systolic BPV, very low frequency VLF-sBP, low frequency LF-sBP and total power spectrum PSD-sBP was noted. CONCLUSIONS: Results of the study suggest that STN DBS is an effective treatment method of both motor symptoms and autonomic dysfunctions. The disturbances of HRV and BPV before and after STN DBS indicate the increase of autonomic system activity with sympathetic dominance.

[AN ANALYSIS OF THE INDICATIONS FOR, AND ASSESSMENT OF THE OUTCOMES OF SECONDARY SURGERY AFTER PRIMARY REPAIR OF INJURIES WITHIN THE UPPER LIMB]. / ANALIZA WSKAZAN DO I OCENA WYNIKÓW PO WTÓRNYCH OPERACJACH PO PIERWOTNYM ZAOPATRZENIU URAZÓW W OBREBIE KONCZYNY GÓRNEJ.

INTRODUCTION: The objective of the study was the analysis of the indications for, and assessment of the outcomes of secondary interventions after primary repair of injuries within the upper limb in the authors' institution--Department of General and Hand Surgery of the Pomeranian Medical University in Szczecin (a tertiary care unit). MATERIAL AND METHODS: Answers on questionnaires (including DASH) mailed to 33 patients were the subject of the analysis. The group consisted of 27 men and 6 women, mean age 36 years, in whom secondary interventions were performed at a mean of 8 months after primary surgery. RESULTS: Injuries were grouped in five categories: tendon lacerations, hand or finger amputations, nerve sections, complex tissue injuries, and isolated finger fractures. The most common cause of secondary intervention was incomplete finger movement and lack of opposition of the thumb. The most common operations included tenolysis, arthrolysis and opponensplasty. The outcomes of secondary surgery from patients' perspective were overall good: 13 (39%) patients reported significant improvement, 16 (48%) moderate, and only 4 (13%) patients had no benefit. Twenty-five patients regained full, or almost full hand function (DASH scores 2-39), and 8 (24%) had moderately to severely impaired function (DASH 40-80). Twenty-eight patients returned to work. CONCLUSIONS: Primary repair of upper limb injuries (even severe) in the tertiary institution was adequate, and secondary interventions rarely necessary. The most common indication was incomplete finger movement caused by ineffective postoperative mobilization. The important role of rehabilitation for the final outcome of the treatment of hand injuries was emphasized.

Lipoid pneumonia--a case of refractory pneumonia in a child treated with ketogenic diet.

Lipoid pneumonia (LP) is a chronic inflammation of the lung parenchyma with interstitial involvement due to the accumulation of endogenous or exogenous lipids. Exogenous LP (ELP) is associated with the aspiration or inhalation of oil present in food, oil-based medications or radiographic contrast media. The clinical manifestations of LP range from asymptomatic cases to severe pulmonary involvement, with respiratory failure and death, according to the quantity and duration of the aspiration. The diagnosis of exogenous lipoid pneumonia is based on a history of exposure to oil and the presence of lipid-laden macrophages on sputum or bronchoalveolar lavage (BAL) analysis. High-resolution computed tomography (HRCT) is the imaging technique of choice for evaluation of patients with suspected LP. The best therapeutic strategy is to remove the oil as early as possible through bronchoscopy with multiple BALs and interruption in the use of mineral oil. Steroid therapy remains controversial, and should be reserved for severe cases. We describe a case of LP due to oil aspiration in 3-year-old girl with intractable epilepsy on ketogenic diet. Diagnostic problems were due to non-specific symptoms that were mimicking serious infectious pneumonia. A high index of suspicion and precise medical history is required in cases of refractory pneumonia and fever unresponsive to conventional therapy. Gastroesophageal reflux and a risk of aspiration may be regarded as relative contraindications to the ketogenic diet. Conservative treatment, based on the use of oral steroids, proved to be an efficient therapeutic approach in this case.

Analysis of the reliability of clinical examination in predicting traumatic cerebral lesions and skull fractures in patients with mild and moderate head trauma.

UNLABELLED: The aim of the study was to assess the reliability of neurological examination and other factors in predicting traumatic cerebral lesions and skull fractures in patients with mild and moderate head trauma (GCS 10-15). MATERIAL AND METHODS: Over a one-year period, 227 patients: 145 male and 82 female, aged a mean of 51 years who sustained mild or moderate head trauma (GSC 10-15) were examined neurologically and had performed head CT scans. The neurological examination as a whole and each finding of the neurological examination were tested as predictors of the presence of traumatic abnormalities in the head CT scan. RESULTS: Post-traumatic lesions in head CT scan were found in 109 patients (48%): skull fractures in 66 of these and brain injuries in 94; fifty-eight patients had skull fracture combined with brain injury. Seventeen patients required neurosurgical intervention (hematoma evacuation). Abnormal neurological examination showed the highest reliability in identifying patients with brain injuries in CT (sensitivity 87%, specificity 79%). Of single findings, gait abnormalities and consciousness disturbances, present in sober patients, were the strongest predictors of cerebral lesions. Likewise, abnormal neurological examination was the best indicator of skull fractures (sensitivity 77%, specificity 63%). Gait abnormalities and "raccoon eyes" present in alcohol intoxicated patients were the strongest individual predictors of skull fractures. CONCLUSION: Results of our study show neurological abnormalities as the most reliable (although not 100% accurate) in identifying patients who are likely to have brain injuries and/or skull fracture following head trauma. Use of clinical decision rules may reduce the number of head CT scans performed "just in case".

Visual feedback training using WII Fit improves balance in Parkinson's disease.

Postural instability including imbalance is the most disabling long term problem in Parkinson's disease (PD) that does not respond to pharmacotherapy. This study aimed at investigating the effectiveness of a novel visual-feedback training method, using Wii Fit balance board in improving balance in patients with PD. Twenty four patients with moderate PD were included in the study which comprised of a 6-week home-based balance training program using Nintendo Wii Fit and balance board. The PD patients significantly improved their results in Berg Balance Scale, Tinnet's Performance-Oriented Mobility Assessment, Timed Up-and-Go, Sit-to-stand test, 10-Meter Walk test and Activities-specific Balance Confidence scale at the end of the programme. This study suggests that visual feedback training using Wii-Fit with balance board could improve dynamic and functional balance as well as motor disability in PD patients.
