There is now a relatively good understanding of the broad range of direct and indirect effects of humor and laughter on perceptions, attitudes, judgments and emotions, which can potentially benefit the physical and psychological state. This article presents a review and discussion of the use of humor and laughter in treating people with serious mental illness, distinguishing between clinical papers on individual and group psychotherapy, and empirical research reports describing humor and laughter interventions. In spite of the exponential growth of the field over the last 30 years, I conclude that empirical studies are still lacking, the studies that do exist have major methodological shortcomings, and the field is in dire need of further investigation.

Construction is one of the important industries employing a large number of people on its workforce. A wide range of activities are involved in it. Due to the advent of industrialization and recent developments, this industry is taking a pivotal role for construction of buildings, roads, bridges, and so forth. The workers engaged in this industry are victims of different occupational disorders and psychosocial stresses. In India, they belong to the organized and unorganized sectors. However, data in respect to occupational health and psychosocial stress are scanty in our country. It is true that a sizable number of the workforce is from the unorganized sectors — the working hours are more than the stipulated hours of work — the work place is not proper — the working conditions are non-congenial in most of the cases and involve risk factors. Their wages are also not adequate, making it difficult for them to run their families. The hazards include handling of different materials required for construction, and exposure to harsh environmental conditions like sun, rain, and so on. On account of this, in adverse conditions, it results in accidents and adverse health conditions cause psychosocial strain and the like. They are victims of headache...

The objective of this paper is to provide a review on the psychiatric comorbidity research in India based on the data published in the last six decades. The comorbidity data world over reflects that it is a much more common phenomenon than observed in routine clinical practice. In India, research into this domain of psychiatry has been limited, with comorbidity reported to be as high as 60%. In the few publications in this area, most of the authors have looked into substance related comorbidity. Small numbers of studies have looked into comorbid conditions in child psychiatry, especially mental retardation and very few studies have looked at other comorbidities. The landmarks in the studies in the area of psychiatric comorbidity have been highlighted in this review article.

Metaplastic carcinoma (MPC), an uncommon but often aggressive breast cancer, can be challenging to differentiate from other types of breast cancer and even benign lesions based on the imaging appearance. It has a variable pathology classification system. These types of tumors are generally rapidly growing palpable masses. MPCs on imaging can present with imaging features similar to invasive ductal carcinoma and probably even benign lesions. The purpose of this article is to review MPC of the breast including the pathology subtypes, imaging features, and imaging pathology correlations. By understanding the clinical picture, pathology, and overlap in imaging characteristics of MPC with invasive ductal carcinoma and probably benign lesions can assist in diagnosing these difficult malignancies.

There is a concern on the risk of thyroid cancer associated with glucagon-like peptide-1 (GLP-1) analogs including liraglutide and exenatide. In this article, we review related experimental studies, clinical trials and observational human studies currently available. In rodents, liraglutide activated the GLP-1 receptors on C-cells, causing an increased incidence of C-cell neoplasia. Animal experiments with monkeys demonstrated no increase in calcitonin release and no C-cell proliferation after long-term liraglutide administration. Longitudinal 2-year data from clinical trials do not support any significant risk for the activation or growth of C-cell cancer in humans in response to liraglutide. However, an analysis of the FDA adverse event reporting system database suggested an increased risk for thyroid cancer associated with exenatide after its marketing. Noticeably, a recent study discovered that GLP-1 receptor could also be expressed in human papillary thyroid carcinomas (PTC), but the impact of GLP-1 analogs on PTC is not known. Therefore, GLP-1 analogs might increase the risk of thyroid C-cell pathology in rodents, but its risk in humans awaits confirmation. Since GLP-1 receptor is also expressed in PTC besides C-cells, it is important to investigate the actions of GLP-1 on different subtypes of thyroid cancer in the future.

Many countries across the world have made newborn screening (NBS) mandatory. It is a laboratory test which screens the newborns for metabolic & genetic disorders, some of which can be treated or modified if detected early in life, and thereby preventing potentially disastrous consequences and saving the baby’s life. The last four decades have witnessed rapid evolution in implementation & strategies used for NBS in US, Europe, Japan & other industrialised nations where NBS is well accepted public health policy. India is going through a progressive transitional phase of control over infant mortality & morbidity due to infections and emergence of genetic conditions. This is the right time to review NBS program in totality considering the global scenario of its initiation, growth, advances in technologies & its transfer from conventional to mass spectrometry techniques, as well as selection & nature of candidate NBS disorders. Nevertheless, the impact of this worldwide movement of NBS is inadequate in India; this review article discusses the various efforts required to successfully introduce this significant health service for population benefits as well as the lacunae & limitations still exist in 21st century in India. Based on the high-risk screening of congenital metabolic conditions using mass spectrometry in India...

Colorectal cancer (CRC) is one of the most common malignancies worldwide. Due to a higher incidence of CRC in the western hemisphere a significant amount of research was carried out and majority of the controversies could be resolved as far as management of CRC is concerned. Recently a number of significant advances were made in the field of CRC related to surgery, systemic therapy and radiotherapy. During the last decade we have witnessed introduction of minimally invasive surgery, incorporation of more effective newer chemotherapeutic regimes and targeted therapies and refinements in radiotherapy protocols. The demographics and clinical picture of CRC seems to be different in developing countries and there is paucity of CRC related studies from developing countries. In-order to update the practicing surgeons a review of conventional controversies of CRC surgery was performed and an update on the recent developments in the field of CRC was also presented in this article.

Soft tissue sarcomas (STS) constitute a rare and challenging group of solid tumor in the field of oncology. Unlike other malignancies STS can affect a wide variety of anatomical regions in the body with varied histo-pathological variants and clinical outcomes. There are controversies in the diagnosis and management of STS due to rarity and heterogeneity of the disease entity. Due to dedicated research and advances made in the field of imaging, pathology, surgery, radiotherapy and chemotherapy certain controversies were laid to rest and treatment approach to STS could be standardized to a large extent in the recent past. A review of controversies related to STS was performed in this article and an attempt was made to present a balanced view pertaining to these issues.

Potentially curable rectal cancer is primarily treated with surgical resection. Adjuvant or neoadjuvant radiotherapy is often utilized for patients deemed to be at unacceptable risk for local recurrence. The purpose of this article is to review the pertinent literature and elucidate the role of radiotherapy in patients with an intermediate risk of local recurrence. The addition of chemoradiotherapy is recommended in the majority of patients with transmural or node positive rectal cancer. However, some patients with favorable characteristics may have only a small incremental benefit from the addition of radiotherapy. The decision to treat or not to treat should take into consideration the patient and physician tolerance of risk of recurrence and risk of treatment related toxicity. The primary factors identified for determining low risk patients are circumferential radial margin (CRM), location within the rectum, and nodal status. Patients at lowest risk have widely negative CRM (>2mm), proximal lesions (>10cm from the anal verge), and no nodal disease. Patients with all three low risk factors have an absolute reduction in local recurrence that is <5% and may be eligible to forego radiotherapy. Additional factors identified which may impact local recurrence risk are elevated serum CEA level...

Liver resections are high risk procedures performed by experienced surgeons. The role of liver resection in malignant disease has changed over the last 100 years with great improvement in morbidity, mortality and long term survival. New understanding in liver anatomy, improved perioperative care, anesthesia techniques, and technological advances has improved this aspect of patient care. With improved techniques, patients previously considered unresectable have an opportunity to undergo curative surgery. This review article describes the various approaches and techniques for liver resection. The relevant anatomy and terminology of hepatic resections is discussed, as well as the role of anatomic vs. nonanatomic resection. Methods of vascular control are examined and the multiple strategies of parenchymal transection are compared, as well as minimally-invasive techniques. Finally, a brief review of the authors’ practice in terms of surgical technique is offered.

Animal models have been developed to simulate angiographic vasospasm secondary to subarachnoid hemorrhage (SAH) and to test pharmacologic treatments. Our aim was to evaluate the effect of pharmacologic treatments that have been tested in humans and in preclinical studies to determine if animal models inform results reported in humans. A systematic review and meta-analysis of SAH studies was performed. We investigated predictors of translation from animals to humans with multivariate logistic regression. Pharmacologic reduction of vasospasm was effective in mice, rats, rabbits, dogs, nonhuman primates (standard mean difference of −1.74; 95% confidence interval −2.04 to −1.44) and humans. Animal studies were generally of poor methodologic quality and there was evidence of publication bias. Subgroup analysis by drug and species showed that statins, tissue plasminogen activator, erythropoietin, endothelin receptor antagonists, calcium channel antagonists, fasudil, and tirilazad were effective whereas magnesium was not. Only evaluation of vasospasm >3 days after SAH was independently associated with successful translation. We conclude that reduction of vasospasm is effective in animals and humans and that evaluation of vasospasm >3 days after SAH may be preferable for preclinical models.

Objectives: The aim of this article is to review the current state of immediate implants, with their pros and contras, and the clinical indications and contraindications. Material and Methods: An exhaustive literature search has been carried out in the COCHRANE library and MEDLINE electronic databases from 2004 to November 2009. Randomized clinical trials and clinical trials focused on single implants placed in fresh extraction sockets were included and compared. A meta-analysis could not be performed due to heterogeneity of the data. Results: Twenty studies out of 135 articles from the initial search were finally included, which summed up a total of 1139 immediate implants with at least a 12-month follow-up. Our results have been compared with other current available papers in the literature reviewed that obtained similar outcomes. Discussion: Immediate implants have predictable results with several advantages over delayed implant placement. However, technical complications have been described regarding this technique. Also, biomaterials may be needed when the jumping distance is greater than 1mm or any bone defect is present. Conclusions: Few studies report on success rates rather than survival rates in the literature reviewed. Short-term clinical results were described and results were comparable to those obtained with delayed implant placement. Further long-term...
