The Effect of Subdural Drain Placement After Burr Hole Evacuation of Chronic Subdural Haematomas...
Chronic Subdural HematomaSubdural DrainThis is a prospective randomised-controlled multi-centre trial based in Hong Kong to determine whether temporary subdural drain placement after burr hole evacuation of a chronic subdural haematoma can reduce the risk of recurrence. Consecutive patients, 60 years old or above, diagnosed to have symptomatic chronic subdural haematoma and indicated for burr hole operative drainage will be randomly allocated into one of two groups: (1) for intra-operative subdural drain placement (intervention group) or (2) not for drain placement (control group). Using web-based software block randomisation with an allocation ratio of 1:1 will be conducted. Instructions to use or not to use a drain will be contained in a sealed envelopes labelled with sequential study numbers. Intra-operatively, if the surgeon-in-charge judges that after burr hole evacuation of the haematoma the patient's condition is unsafe for drain placement, the subject will be excluded from the study. Otherwise, randomisation will be performed at this juncture by the opening of the sealed envelop. The procedure involves placing a prefabricated silicon drain into the subdural space according to a standard protocol and will be removed on the second post-operative day at the bedside. Subjects in whom the operating surgeon judges that drain placement is unsafe will be excluded from the study. Drainage is undertaken passively by hanging the collection bag at the bedside in a dependent position. In addition to general demographic, clinical and radiological presentation data, potential risk factors for recurrence will be documented. Serial computed tomography brain scans will be arranged (before discharge, at four weeks and six months) and the occurence of significant subdural haematoma recurrence requiring repeat operative drainage at six months will be recorded. Other outcome measures to be determined at regular time intervals for a total follow-up period of six months (upon discharge, at four weeks and six months) include: functional performance in terms of the extended Glasgow Outcome Scale and modified Rankin Scale, added neurological deficit, death and other surgery-related complications. All outcomes will be documented by the trial investigators or by the responsible clinician. The data obtained will be analysed according to the principle of intention to treat. Hypothesis: compared to burr-hole evacuation of chronic subdural haematoma alone (control), the additional placement of a subdural drain after evacuation (intervention) will reduce the risk of recurrence requiring repeat surgery.
Prevention of Postpartum Smoking Relapse in Mothers of Infants in the Neonatal Intensive Care Unit...
SmokingThe investigators hypothesized that an enriched focus on mother-infant bonding during a newborn's hospitalization in the Neonatal Intensive Care Unit would reduced the rate maternal postpartum smoking relapse and would prolong the duration of breastfeeding in mothers who had quit smoking during or just prior to pregnancy.
A Randomised Trial of a Moisturising Cream in Preventing Recurrence of Hand Eczema
Hand EczemaThe purpose of this study is to investigate whether a moisturizing cream can prevent hand eczema.Patients with previous hand eczema will be studied. In the second part of the study, it will be explored if a treatment regimen of a topical corticosteroid once daily is not inferior to treatment twice daily.
Determinants of Pterygium Occurrence and Recurrence in a Rural African Population
PterygiumThe aim of the study is to find out why pterygium occurs and recurs in a rural African population. Participants will be interviewed on personal and lifestyle information, family history of pterygium, environmental exposure and history of previous eye inflammation. They will undergo eye examination and photography. Those with pterygium will be operated on to remove pterygium and followed up to detect any recurrence and complications of surgery. The excised pterygium will be examined pathologically and genetically; participant's blood will also be examined genetically. Data will be analyzed for statistically significant differences in findings between pterygium and pterygium free participants. The study hypothesis is that multiple factors are responsible for the occurrence and recurrence of pterygium in a rural african population.
Study of the Efficacy of Maintenance Therapy Using Uracil-tegafur (UFT) or Bacille Calmette-Guerin...
Bladder CancerThe purpose of this prospective randomized controlled study is to prove the non-inferiority of UFT maintenance therapy to BCG maintenance therapy for preventing recurrences of superficial bladder cancer.
Mindfulness-based Treatment to Prevent Smoking Relapse
Smoking CessationBackground: Smoking causes a variety of health problems and causes burden to healthcare systems. Even when support is provided, local data suggest that around 50% of biochemically confirmed quitters resume smoking within 6 months of participating in a smoking cessation program. Mindfulness-based intervention is a promising option because accumulating evidence from randomized controlled trials support its use among smokers. Our team aims to determine if mindfulness-based interventions can prevent relapse in smokers who recently quit smoking. A pilot trial is needed to determine the feasibility of recruitment, randomisation and acceptability of the intervention in these patients Method: Forty participants, who just quitted smoking, will be randomised in a 1:1 ratio to the 8week mindfulness-based relapse prevention (MBRP) program and to usual care.
The Difference of Two Year Recurrence Rate According to Anesthetic Method During Transurethral Resection...
Bladder CancerThe investigators compare the recurrence rate difference between two years after transurethral resection of the bladder tumor according to the method of anesthesia. Anesthetic methods are general anesthesia and spinal anesthesia. Assessment of recurrence is assessed by bladder endoscopy, CT, and pathological examination of surgical specimens.
Technical Performance Assessment of Tc-99m Tetrofosmin for Differentiation of Recurrence vs Radiation...
Glioma (Diagnosis)This study aims to assess the technical performance of Tc-99m tetrofosmin SPECT as compared to F-18 FDG PET for the differentiation of radiation necrosis from glioma relapse and to obtain estimates of diagnostic accuracy for Tc-99m tetrofosmin SPECT and F-18 FDG PET in an intra-individual comparison.

Evaluation Study of Fear of Cancer Recurrence: Detection, Measure and Risk Factors in Lymphoma Survivorship...
LymphomaCancer survivorship has become an important aspect of oncology research due to the risk of physical and psychosocial complications. These latter concerns 50 % of patients. So, the aim of this research is to measure frequency and intensity of one of these issues: the fear of cancer recurrence (FCR) in the lymphoma survivorship beginning, at M0.
