Role of Family System, Positive Emotions and Resilience in Social Adjustment among Pakistani Adolescents

AbstractThe present study explored the role of positive emotions, resilience & family system in social adjustment in Pakistani adolescents.  Through convenient sampling, data  collected from 150 adolescents (70 boys & 80 girls).In terms of family system 92 were living in nuclear family while 58 injoint family. Urdu version of Modified Differential Emotions Scale, Resilience Scale and Bell`s Adjustment Inventory were used. Statistical analysis revealed the presence of significant positive relationship between positive emotions and resilience (r = .39**) where girls were slightly more resilient (M ± SD = 120.77 ± 24.03) & socially adjusted (M ± SD = 17.41 ± 4.15). Moreover 52 % adolescents reported difficulty in talking with new people. Majority of participants from Joint family reported good social adjustment (38%) and high resilience (17%) as compared to those in nuclear family (21%, 13%).  The influence of these demographic variables is important indication to be explored further.Keyword: Family system, Positive emotion, and resilienc

Histological pattern of ovarian neoplasma.

Abstract Objective: To see the morphological pattern of benign and malignant ovarian neoplasms. Method: Retrospective study of all consecutive cases of ovarian neoplasms diagnosed at Aga Khan University Hospital between 1st January 1993 and 30th September 1998. Setting: The Section of Histopathology, AKUH, Karachi. Observation: Of 855 ovarian tumours 506 (59.18%) were benign and 349(40.81%) malignant. Surface epithelial - stromal tumours comprised 63.50% of all tumours. Benign cystic teratoma was the commonest benign tumour (35.17% of all benign tumours) and serous cystadenocarcinoma was the commonest malignant tumour (33.33% of all malignant tumours). Mucinous cystadenocarcinomas are more common in our population as compared to the West and borderline and malignant mucinous tumours occur at a younger age group. Malignant germ cell tumours are also common in our population. Conclusion: Except for the greater frequency of malignant mucinous and germ cell tumours, the findings of our series correspond to the published Western data (JPMA 50:416, 2000)

Histological pattern of central nervous system neoplasms

Objective: To see in a large series of patients the histological pattern of CNS neoplasms and to provide a comprehensive data about the frequency of CNS neoplasms in Pakistani patients and to give a clearer idea about their prevalence. Method: Retrospective study of all consecutive cases of CNS neoplasms diagnosed at The Aga Khan University Hospital (AKUH) between 1st January 1994 and 31st December, 1999. Setting: The section of Histopathology, AKUH, Karachi. Observation: Our series included a large number of cases i.e., 1110 . There are very few local studies on CNS tumours and none so large . Our data was correlated with published Western and Pakistani data . Glial tumours were the commonest primary CNS neoplasms followed by meningiomas . Among glial tumours , astrocytomas comprised the largest group and the majority were high grade (Ill and IV ) astrocytomas. Percentages of anaplastic oligodendrogliomas and ependymomas were also significant. Male to female ratio was 1.6:1. However, meningiomas were more common in females. Almost half of the CNS tumours in patients 15 years or younger were in the posterior cranial fossa . Metastatic tumours were much lower as compared to the West. Conclusion: Except for the high percentages of anaplastic oligodendrogliomas and ependymomas and the low percentage of metastatic tumours, most of our findings roughly correspond with the published data

Central nervous system lymphomas: a histologic and immunophenotypic analysis

Objective: To observe the spectrum of non-Hodkin’s lymphomas involving the central nervous system including morphological subtypes and immunophenotypic status. Setting: Retrospective analysis of eleven years (1986 to 1996) data from surgical pathology files of Department of Pathology. Results: orty-three cases of non-Hodgkin’s lymphomas were diagnosed during the period of eleven years (from 1986 to 1996), all of which were diffuse types. A total of 1177 Central Nervous CNS biopsies were examined, out of which 937 cases were diagnosed as CNS neoplasms, the remaining were non-neoplastic in nature. Among 937 CNS neoplasms, 43 cases (4.6%) were reported as non-Hodgkin’s lymphomas. As most of the cases were outside referrals, the primary or secondary nature of the lymphomatous process could not he assessed. Seventeen cases were intracranial, while 26 cases were spinal in location. Majority of the intracranial Eymphomas were hiopsied from the cereherum (12 cases). Male to female ratio was 1:2. The median age for intracranial lvmphomas was 50 years and for spinal lymphomas 29 years. There were 16 cases (37%) of diffuse large cell lymphomas; 7 cases (16%) of diffuse mixed small and large cell lymphomas; 3 cases (7%) of diffuse large cell immunoblastic lvmphomas; 2 cases (4.6%) of lymphoblastic lymphomas and diffuse small non-cleaved cell lymphomas and one case of small Iyrnphocytic lymphoma and diffuse small cleaved cell Ivmphoma. One case of T cell rich B cell lvmphoma was also diagnosed in the thoracic spine as primary extranodal lymphoma. Eight cases were unclassifiable and in 2 cases the features were suggestive of lymphoma. Immunophenotypic analysis was performed in 20 cases, however, in 2 cases the results were inconclusive. Fifteen cases (83%) showed immunoreactivity for B cell markers and 3 cases showed T cell phenotype out of which one case was lymphoblastic lymphoma. Conclusion: CNS lymphomas were uncommon tumors and comprised 4.6% of the total CNS neoplasms in our study. Moreover, these CNS lymphomas accounted for 2.2% of the total non-Hodgkin’s lvmphomas, including both nodal and extranodal. There was a higher incidence of location of these lymphomas within the spinal cord than brain. Most of the lymphomas were of intermediate or high grade (75%) according to the working phenotype in 84% 3f the lymphomas, in which it was formulation. lmmunophenotypical status revealed B-cell teste

Morphological pattern of salivary gland tumours

Objective: To delineate the spectrum of salivary gland tumors in our setup. Setting: The Aga Khan University Medical Centre, Karachi. Method: Tumors were analysed considering histological type, age and sex of the patients and anatomic location. The diagnosis of individual tumours was based on the 1991 World Health Organisation Classification. Results: During the span of eight years (1991-1998), 379 cases of salivary gland tumours were diagnosed. Of these, 205 (65.7%) were male and 174 (34.3%) were female. The median age at the time of diagnosis was 35 years. The median age for patients with malignant lesions (44 years) was 12 years older than those with benign tumours (34 years). Overall, malignant tumours were seen more frequently in males, however benign tumours were distributed equally between the two sexes. The most common site was parotid gland (82.85%). Only five cases of minor salivary gland tumours were seen. The most frequently diagnosed benign salivary gland neoplasm was pleomorphic adenoma (84.5%), followed by Warthin’s tumours (6.18%), Mucoepidermoid carcinoma was the most commonly encountered malignant lesion (56.9%), followed by adenoid cystic carcinoma (19.6%). Conclusion: Plemorphic adenoma was the most common benign salivary gland tumour and mucoepidermoid carcinoma was the most frequent malignant neoplasm. Parotid gland was the most common site of origin in both benign and malignant tumours. The overall relative frequency of salivary gland tumours in this series correlates with that reported in the international literature

Retinoblastoma tells the story of our health care system

Objective: To review cases of retinoblastoma. Setting: Department of Pathology Aga Khan University Hospital Karachi. Method: Twenty three specimens from cases of retinoblastoma received over a period of eight years were routinely processes and stained with haematoxylin and Eosin stain Other stains were used for tuberculosis and melanin. Immunochemistry was resorted to in undifferentiated tumors. Results: Over 60% cases of retinoblastoma were diagnosed after 5 years and nine cases showed involvement of opti-nerve. Conclusion: Late diagnosis of retinoblastoma effects the stage of the tumors and the prognisis

Breast Diseases: a histopathological analysis of 3279 Cases at a Tertiary Care Center in Pakistan

Objective: To know the frequency of breast diseases in Pakistani females. Methods: A retrospective analysis of 3279 breast specimens received over a period of 4 years (1 993-1996) at the department of pathology, the Aga Khan University Hospital. Results: Out of a total of 3279 breast specimens, common breast lesions included infiltrating duct carcinoma 37%, followed by fibro adenoma 16.95%, fibrocystic change13.96%, mastitis 6.83% and duct ectasia 5.33%. Majority of the cases of infiltrating duct carcinoma were encountered in the 5th and 6th decades of life. Tumour size was 2 or \u3e2 cms. in 93% of cases and 40% of them showed 3 or \u3e3 positive lymph nodes. Grade I tumours were 11.38%, grade 11 59.17% and grade Ill tumours 29.47%. Correlation of grade with lymph node metastases (3 or \u3e3+ve nodes) showed 15 cases (1.53%) of grade 1, 178 cases (18.25%) of grade II and 68(6.97%) cases of grade Ill tumours. Conclusion: This study shows that in Pakistani females, the most commonly encountered lesion in carcinoma of the breast followed by the benign lesions such as fibro adenoma, fibrocystic disease & others. Breast carcinoma occurs at a younger age group with predominance of high-grade lesions and with frequent lymph node metastasis
