Abstract Modern anthropological research includes very sophisticated diagnostic methods. They allow us to obtain information that has not been available so far. The aim of this paper is to analyze, using current microscopic technologies, the Mesolithic dental material of one adult individual from Woźna Wieś (Poland). The present case study will focus on the analysis of enamel hypoplasia. A scanning electron microscope (SEM) was used to count the number of perikymata building on the hypoplastic line. Linear enamel hypoplasia (LEH) was diagnosed only on the right mandibular canine. The time of occurrence of environmental disturbance was estimated between about 4.2 and 4.9 years of age. The occlusal wall built the enamel hypoplasia with no more than three to four perikymata, meaning that the physiological stress had to have occurred over a fairly short period of time (about 30-40 days).

Paleopathological and paleoparasitological studies seek evidences to understand health and disease in past populations. These two approaches are often used independently despite the obvious importance of its complementary. This paper aims to explore the possible relation between a common indicator of childhood stress and infection by intestinal parasites. Thirty adult individuals from the Islamic necropolis of Santarém (9th-12th cent. AD) were macroscopically examined for linear enamel hypoplasia. Sediment from the pelvis and skull of each skeleton were observed under the optical microscope in search of helminth eggs. Hypoplasic defects were identified in 46.67% of the individuals, mostly on canines and incisors. Eggs from Ascaris lumbricoides and Trichuris trichiura were identified respectively in 4 and 2 individuals. The Fisher’s exact test was performed to analyze whether the individuals with evidences of stress in early childhood were more prone to helminth infections or death at younger ages. Although these variables were shown to be independent, this exploratory study highlights the contribution of combining paleopathological and paleoparasitological methods to address the long-term impact of the physiological stress exposure in early life on the immune system. Furthermore, variety of factors that could have influenced these results are discussed and interpreted in a biocultural perspective.

Abstract Linear enamel hypoplasia (LEH) is treated as a nonspecific indicator of stress, but even so, many authors consider it the most reliable tool stress in anthropological research. Its analysis allows the reconstruction of health related to the socio-economic status of the group. This study documents and interprets patterns of LEH in Żerniki Górne (Poland), a settlement which was functional in the Late Neolithic and the Early Bronze Age. We examined two successive cultures: the Corded Ware Culture (CWC; 3200-2300BC) and the Trzciniec Culture (TC; 1500-1300BC). In total, there were 1486 permanent teeth (124 adult individuals). The frequency of LEH in the examined cultures shows a small rising trend. In these series from Żernik Górne, males showed a higher occurrence of LEH (16.5%) than females (13.4%). The earliest LEH appeared at similar ages at about 2.0/2.2 years and the last LEH occurred at about 4.2 years of age in both cultures. However, it is worth noting that periods associated with physiological stress were more common but not very long (four months on average) in the CWC. Longer stress periods (nine months on average) were associated with the TC.

Resumo: O romance histórico Yaka, de Pepetela, narra o último século de administração portuguesa em Angola e as múltiplas resistências das populações nativas à ocupação colonial até a conquista da independência. Na construção da nação angolana, o pano de fundo do romance, uma narrativa sutil surge nas entrelinhas. Esse espaço liminar de representação articula as dificuldades de definição do que se tornaria representativo de uma ideia, ou um ideal, de “angolanidade” que foi construída concomitantemente à projeção da nação. A complexidade do enquadramento político e cultural que definiria a identidade nacional angolana decorre das experiências da história colonial, que, mais do que (re)inventar as fronteiras do que viria a ser a geografia política do país em busca da independência, teve um papel fundamental na definição do que constituiria o povo angolano – seja colocando juntos diferentes povos que originalmente habitaram esse vasto território, ou pelo assentamento de uma quantidade significativa de colonizadores brancos nos espaços conquistados. Depois de tantos anos de histórias e memórias compartilhadas entre colonizadores e colonizados, que características seriam consideradas como fontes legítimas de pertencimento nacional? Que fronteiras demarcaram a “angolanidade” funcionando como base para a construção da identidade nacional angolana? Quem teria direito à cidadania após o processo de independência? Estas questões orientaram o presente estudo de caso, que, ao ler Yaka como um romance histórico constitutivo das narrativas angolanas de pertencimento elaboradas já em uma conjuntura pós-colonial, reflete sobre os processos de exclusão/inclusão da população não negra na construção de uma ideia ou ideal de “angolanidade”.Palavras-chave: Pepetela; angolanidade; pertencimento; identidade nacional.Abstract: Pepetela's historical novel Yaka narrates the last century of Portuguese colonial presence in Angola and the multiple forms of resistance of native populations to colonial occupation until the conquest of independence. In the construction of the Angolan nation, the background of the novel, a subtle narrative appears between the lines. This liminal space of representation articulates the difficulties of defining what would become representative of an idea or an ideal of “Angolanity” that was constructed concomitantly with the projection of the Nation. The complexity of the political and cultural framework that would define Angolan national identity stems from the experiences of colonial history, which, more than (re)inventing the borders of what would become Angolan political geography, played a fundamental role in defining what would constitute the Angolan people – by putting together different peoples who originally inhabited this vast territory, or by the settlement of a significant population of white settlers in the conquered spaces. After so many years of stories and memories shared between colonizers and colonized, what characteristics would be considered as legitimate sources of national belonging? What frontiers demarcated the “Angolanity”, functioning as a basis for the construction of Angolan national identity? Who would have the right to citizenship after the independence process? These questions guided the present case study which, reading Yaka as a historical novel constitutive of the Angolan narratives of belonging elaborated in a postcolonial conjuncture, reflects on the processes of exclusion/inclusion of the non-black population in the construction of an idea or ideal of “Angolanity”.Keywords: Pepetela; angolanity; belonging; national identity.

The ankle joint is the most common site for a ligament injury in the body. Some ankle joint injuries are minor and heal with some rest from activities, but some are serious and require immediate medical attention. An ankle sprain refers to ligament injuries of the ankle. In classics, there is no direct reference regarding sprain and its manage- ment. In Susrutha Samhitha Chikitsa Sthana 3rdchapter, Bhagna Chikitsitham, Acharya Susruta has mentioned the application of Manjishtadi Lepa for traumatic joint injuries. In the present case study, a 22 years old male pa- tient visited the OPD with severe pain and swelling of the right ankle following a twisting injury of the foot. He was diagnosed with a grade 1 ankle sprain and was bandaged with Manjishtadi Lepa. Management with Man- jishtadi Lepa has shown significant relief in pain and swelling as well as in the restoration of normal movements. Keywords: Ankle sprain, Manjishtadi Lepa

Ayurveda described various skin diseases under the single heading Kushta. In Charaka Samhita, Acharya Charaka explained Ashtadasha Kushtas in two main categories namely ‘Maha Kushta’ and ‘Kshudra Kushta’. Kushta is tridoshaja vyadi, however, the symptoms appear according to the dosha predominance. Vipadika is one of the Kshudra Kushta with predominance of vata kapha doshas and it is charactrised by Pani Pada sputana (fissures in palms and soles) and Teevra vedana (severe pain). According to clinical manifestations, Vipadika is more similar to ‘Planto Palmar Psoriasis’ which is long lasting Auto Immune disease. It is found to be 3-4% of all Psoriasis cases. In modern science, many treatment modalities are available to treat the disease. They may cause many side effects and recurrence after subside is also very common which gave a big scope to alternative system of medicines to treat Vipadika. In the present case study, the line of management followed was mentioned by Acharya Charaka, according to dosha Predominance. The patient, initially administered sneha pana with Maha Tiktaka gritha for 7 days which was beneficial to pacify pitta dosha and kapha dosha utkleshana before Vamana. Later on, Vamana therapy was conducted to eliminate kapha dosha which gave good symptomatic relief to the patient. However, in view of the severity, chronicity and recurrence of the disease, Mridu Lavana jala Avagaha Sweda followed by Padhabyanga with pinda taila was also performed which resulted in excellent improvement in very short period of time.

Enamel hypoplasia is a dental pathology that forms when an individual is exposed to physiological stress in early life while tooth crowns are developing. Biological anthropologists utilize these enamel defects as indicators of growth interruption and interpret them as reflective of factors pertaining to health status and cultural practices that influence health. Over decades of research, numerous studies have noted a pattern in the distribution of linear enamel hypoplasia across the dentition. It is suggested that the anterior dentition presents the highest frequency of defects, followed by the premolars, with molars most rarely exhibiting hypoplasia. This apparent differential susceptibility pattern has resulted in the preferential study of the anterior dentition in anthropology, however little research has been conducted into the validity or cause of this developmental phenomenon. Through examination of the literature, the observed higher frequency of enam2el hypoplasia in the anterior dentition substantiates the existence of this differential distribution pattern. Further investigation reveals that the cause of this varying susceptibility has not been sufficiently explored, leading to a number of inconclusive explanations. Examination of these theories – ranging from the chronology of tooth development, specifics of crown morphology, and variations in genetic control – indicate that there is no single causal variable, but that a multitude of factors are responsible. From this research it is apparent that further study is necessary to fully understand why the anterior teeth appear to be more susceptible to hypoplastic defects than their posterior counterparts.

Linear enamel hypoplasia (LEH), a defect in enamel formation, has been frequently attributed to malnutrition and other physiological stress during periods of enamel development (Sarnat and Schour, 1941; Kreshover, 1960). LEH has been widely used as an indicator of developmental stress in skeletal studies among historic and prehistoric populations (Goodman et al., 1980; Corruccini et al., 1985; Goodman and Rose, 1990). A study of 3,014 subjects in 26 birth-year cohorts, samples from urban and rural communities of China, indicated that significant differences in LEH frequencies occurred between persons whose teeth developed during the famine years (1959-1961) and those whoe teeth calcified during non-famine years. This result points to a causal link between enamel hypoplasia and childhood nutritional stress at the population level, and casts some light on the magnitude and effects of the little-documented Chinese famine.

Twin studies have mostly focused on the pattern of maladaptive behaviour manifested by the twins and their biological basis but the findings have remained controversial till date. The present case study explores the psychopathology in 14 year old twins of Indian origin. They were referred for psychometric assessment and psychotherapy for their conduct problems. The tools administered on them during psychometric assessment are Wechsler Intelligence Scale for Children IV (WISC-IV), Rorschach Inkblot Test (RIBT) and Thematic Apperception Test (TAT). Findings are discussed in terms of the personality processes and relationship quality of the twins.
