Establishment of a formal program for retinoblastoma: Feasibility of clinical coordination across borders and impact on outcome

Retinoblastoma is an ocular tumor that occurs in young children, in either heritable or sporadic manner. The relative rarity of retinoblastoma, and the need for expensive equipment, anesthesia, and pediatric ophthalmologic expertise, are barriers for effective treatment in developing countries. Also, with an average age‐adjusted incidence of two to five cases per million children, patient number limits development of local expertise in countries with small populations. Lebanon is a small country with a population of approximately 4.5 million. In 2012, a comprehensive retinoblastoma program was formalized at the Children's Cancer Institute (CCI) at the American University of Beirut Medical Center, and resources were allocated for efficient interdisciplinary coordination to attract patients from neighboring countries such as Syria and Iraq, where such specialized therapy is also lacking. Through this program, care was coordinated across hospitals and borders such that patients would receive scheduled chemotherapy at their institution, and monthly retinal examinations and focal laser therapy at the CCI in Lebanon. Our results show the feasibility of successful collaboration across borders, with excellent patient and physician adherence to treatment plans. This was accompanied by an increase in patient referrals, which enables continued expertise development. However, the majority of patients presented with advanced intraocular disease, necessitating enucleation in 90% of eyes in unilateral cases, and more than 50% of eyes in bilateral cases. Future efforts need to focus on expanding the program that reaches to additional hospitals in both countries, and promoting early diagnosis, for further improvement of globe salvage rates.     

Palliative care for families: remembering the hidden patients.

Families of patients receiving palliative care are profoundly affected by the challenges of the illness. They observe care that the patient receives, provide care for the patient, and receive support from health professionals in the form of information, counselling, or practical assistance. As they witness and participate in the patient's care, they judge the quality of care that the patient receives. They often see themselves as the patient's care advocates and may harbour regret and guilt if they believe that the patient did not have the best possible care. The illness experience profoundly affects family members' psychological and physical health; recognition of this has coined the term "hidden patients." This article briefly synthesizes empirical work that suggests how to best support families in a palliative care context. We discuss how to define the family, emphasizing a systems approach to family care. We describe the impact of the illness on the family in terms of family members' health, family communication issues, psychological issues, needs for information, physical care demands, and family costs of caring.     

Intrathecal and oral clonidine as prophylaxis for postoperative alcohol withdrawal syndrome: a randomized double-blinded study

In this study, we evaluated the effect of intrathecal and oral clonidine as supplements to spinal anesthesia with lidocaine in patients at risk of postoperative alcohol withdrawal syndrome (AWS). We hypothesized that clonidine would have a prophylactic effect on postoperative AWS. Forty-five alcohol-dependent patients (daily ethanol intake >60 g) scheduled for transurethral resection of the prostate were double-blindly randomized into three groups. All patients received hyperbaric lidocaine 100 mg intrathecally. The diazepam group (DiazG) was premedicated with diazepam 10 mg orally; the intrathecal clonidine group (Clon(i/t)G) received a placebo (saline) tablet and clonidine 150 microg intrathecally; and the oral clonidine group (Clon(p/o)G) received clonidine 150 microg orally. For patients diagnosed with AWS, the Clinical Institute Withdrawal Assessment for Alcohol, revised scale, was used. Twelve patients in the DiazG had symptoms of AWS, compared with two in the Clon(i/t)G and one in the Clon(p/o)G. The median Clinical Institute Withdrawal Assessment for Alcohol, revised scale, score was 12 in the DiazG versus 1 in the clonidine-treated groups. Two patients in the DiazG had severe delirium. Patients receiving oral clonidine had a slightly decreased mean arterial blood pressure 6-12 h after spinal anesthesia (P < 0.05); patients in the DiazG had a hyperdynamic circulatory reaction 24-72 h after surgery. In conclusion, preoperative clonidine 150 microg, intrathecally or orally, prevented significant postoperative AWS in ethanol-dependent patients. IMPLICATIONS: In this randomized, double-blinded study, clonidine 150 microg both intrathecally and orally prevented postoperative alcohol-withdrawal symptoms in alcohol-dependent men. The effect was superior to that with a single dose of diazepam 10 mg orally.     

Obsessive-compulsive disorder: unearthing a hidden problem

Obsessive-compulsive disorder (OCD) is the fourth most common psychiatric disorder. Yet patients often avoid seeking help because they are ashamed. Diagnosis is difficult, but familiarity with the nature of OCD and its current management helps primary care physicians identify patients with OCD and make informed judgments about treatment and referral. We review common symptoms, causes, drug therapy, behavioral therapy, and quality of life issues in patients with OCD.     

Pulmonary function tests in children with adenotonsillar hypertrophy

OBJECTIVE: Adenotonsillar hypertrophy, a common malady in children may lead on to cardiopulmonary dysfunction in untreated cases. The present study was designed to see alteration in pulmonary function tests i.e. spirometric parameters and blood oxygen saturation consequent to adenotonsillar hypertrophy and subsequent changes after adenotonsillectomy. METHODS: Spirometry and pulse oximetry were carried out in 40 children with adenotonsillar hypertrophy of both sexes between the age of 7 and 14 years and 40 age and sex matched healthy children. The test was repeated one and half months after surgery in study group and data was statistically analyzed using students' t-test. RESULTS: The flow volume plot was abnormal in all the patients along with hypoxia, reduced FIF50% and, increased FEF50%/FIF50%, FEV1/PEFR, FEV1/FEV0.5 ratios. There was statistically significant improvement in above parameters following surgery. CONCLUSIONS: Spirometry can prove an useful diagnostic tool in adenotonsillar hypertrophy for deciding early intervention to prevent cardio pulmonary complications.     

Preventive Care in the Context of Men's Health

This study assessed the effectiveness of a health intervention, in diabetes education and risk assessment, to motivate men to take positive action, within the framework of the Health Belief Model. The worksite-based intervention targeted 525 men aged between 40 and 65 years from 27 organizations in the south-west of Western Australia in 1999/2000. Men identified as high risk were referred to their general practitioner. The adopted strategy had a number of strengths, namely that the health risk assessment was topic-specific, personalized, conducted on the worksite and combined with an educational component and a medical follow-up. The focus groups component of the study gave further understanding as to why the adopted strategy had been appropriate for men's needs.     

Oxygenation using tidal volume breathing after maximal exhalation

We compared, in volunteers, the oxygenation achieved by tidal volume breathing (TVB) over a 3-min period after maximal exhalation with that achieved by TVB alone. Twenty-three healthy volunteers underwent the two breathing techniques in a randomized order. A circle absorber system with an oxygen flow of 10 L/min was used. The end-expiratory oxygen concentration (EEO(2)) was monitored at 15-s intervals up to 3 min. TVB after maximal exhalation produced EEO(2) values of 68% +/- 5%, 75% +/- 5%, and 79% +/- 4% at 30, 45, and 60 s, respectively, which were significantly larger (P < 0.05) than the corresponding values obtained with TVB alone (58% +/- 5%, 66% +/- 6%, and 71% +/- 5%, respectively). In both techniques, the EEO(2) increased exponentially, with time constants of 35 s during TVB after maximal exhalation versus 58 s during TVB without prior maximal exhalation. In conclusion, maximal exhalation before TVB can hasten preoxygenation by decreasing the nitrogen content of the functional residual capacity, with a consequent increase of EEO(2) to approximately 70% in 30 s and 80% in 60 s. IMPLICATIONS: Oxygenation by using maximal exhalation before tidal volume breathing produced a significantly faster increase in end-expiratory oxygen concentration than oxygenation with tidal volume breathing alone.
