Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is extremely rare, and most of them are immediately treated for radical resection. However, the information concerning its natural history remains unclear. In this report, we presented a patient with parapharyngeal SFT/HPC, who was not immediately treated with surgical resection at first diagnosis. After approximately 3 years, the tumor volume doubling time (TVDT) and specific growth rate (SGR) could be measured through 3 serial magnetic resonance imagings. The TVDTs in the early and late pretreatment stages were 350 and 180 days, respectively, while the SGRs were 0.002 and 0.003, respectively. The growth rate of this disease entity is generally slow and may accelerate in the disease process.

Diagnosis in Ayurveda is not always in terms of the name of the disease but in terms of the nature or phenomenon. This phenomenon is described in terms of Samprapti of the disease in each patient, comprising Dosha, Dushya and Adhishtana components. The prime factors in the pathogenesis of the disease are Dosha and Dushya. Shat kriyakala refers to the stage of development of a pathological process in which a physician can intervene by the most accurate treatment modality and medicine, thereby halting the progression of the disease process. By intricate understanding of the process of Shat kriyakala, the disease process could be arrested, and further complications can be avoided. In the current scenario, the concept of prevention has become broad-based. The natural history of disease is one of the significant elements of epidemiology. The course of a disease takes in individual people from its pathological onset until its eventual resolution. Natural history of disease is possible to correlate pre-pathogenesis with Sanchaya, Prakopa, Prasara and pathogenesis with Sthanasamsraya, Vyakti and Bhedavastha of Shat kriyakala. Recent studies have shown that it is possible to identify certain pre-clinical stages for many diseases like Parkinson’s disease, which can help in the early successful treatment. Shat kriyakala helps to arrest the disease process at the very early stage itself. Along with current technology, the need for research for validating the Shat kriyakala will benefit humankind in the long run.

BackgroundSpontaneous dyskinesia and parkinsonism have been reported in never-medicated patients with schizophrenia but there has been no previous study of the natural history of these conditions.AimsTo determine the prevalence of spontaneous dyskinesia and parkinsonism in a group of never-medicated, chronically ill patients with schizophrenia on two occasions separated by an 18-month interval.MethodDyskinesia was assessed by the Abnormal Involuntary Movements Scale using Schooler and Kane criteria for its presence; parkinsonism by the Simpson and Angus scale; and mental state by the Positive and Negative Syndrome Scale for schizophrenia.ResultsThirty-seven patients were examined on two occasions. Nine (24%) had dyskinesia on both occasions, 12 (33%) on one occasion and 16 (43%) on neither occasion. Twenty-one (57%) had dyskinesia on at least one occasion. Thirteen patients (35%) had parkinsonism on at least one occasion.ConclusionsSpontaneous dyskinesia and parkinsonism fluctuate over time. The former was found on at least one occasion in the majority of patients. It is an integral part ofthe schizophrenic disease process.

Childhood Rhabdomyosarcoma

There is a need for a rational and useful staging system for childhood rhabdomyosarcoma that predicts prognosis based on the biology and natural history of the disease. Important factors to consider are age, histology, tumor volume, extent of invasion, and lymphatic involvement. A clinical staging system based on a classical tumor/node/metastasis status, and which accounts for natural history as a function of site of primary, local invasion, and lymphatic or hematogenous metastases is presented. This staging system eliminates the requirement that stage is assigned following an initial therapeutic strategy and removing the implication that prognosis is determined by that strategy.
