Chromoblastomycosis in Nepal: a study of 13 cases.

Abstract: Background: Chromoblastomycosis is a chronic fungal infection caused by several pigmented fungi commonly seen in tropical and subtropical climates. Aim: To evaluate the epidemiologic, clinical and pathological characteristics of chromoblastomycosis in our patients. Methods: This retrospective and prospective study was conducted at the Manipal Teaching Hospital, Pokhara, Nepal. Clinical features and histopathology of all the cases diagnosed as chromoblastomycosis during the last eight years were studied. Results: A total of 13 cases of chromoblastomycosis were diagnosed during the period of 1999 - 2006. The disease was seen predominantly in middle-aged male farmers and those from rural areas. The lesions commonly involved the lower extremity and were single or multiple in number. They clinically presented as verrucous or nodular growths. Out of these 13 cases, three were diagnosed clinically as squamous cell carcinoma and one as psoriasis. The histopathological features included sclerotic bodies in 12 cases (92%), microabscess formation in 10 cases (76.9%), pseudoepitheliomatous hyperplasia in nine cases (69.2%) and granuloma in eight cases (61.5%). Conclusion: Farming is the commonest occupation in patients with chromoblastomycosis. Early histological diagnosis helps in effective management of the condition.

Utility of fine needle aspiration cytology in metastatic lymph nodes

Abstract: Background: Fine needle aspiration cytology is a reliable as well as an inexpensive diagnostic method. It is suitable for the developing countries like Nepal for the diagnosis of lymphadenopathy at any approachable site. Fine needle aspiration cytology not only confirms the presence of metastatic disease but also, in most cases, gives the clue regarding the origin of the primary tumor. The aim of the study was to find out the cytological diagnosis of metastatic lymph node lesions. Materials and Methods: A combined prospective and retrospective study was done of all metastatic lymph node lesions (including both superficial and deep nodes) reported in Department of Pathology, Manipal Teaching Hospital, Pokhara from January 2005 to Deceember 2010. Results: A total of 4180 cases of fine needle aspiration cytology were carried out of which 508 cases were of lymph node. Cytology results were unsatisfactory in 58 specimens (12%), “reactive” or “infective” in 347 specimens (68%), positive for metastasis in 93 specimens (18%) and hematolymphoid malignancies include 10 cases (2%). The most common site was anterior and posterior triangles cervical nodes. The most common malignancy was adenocarcinoma, seen in 62 cases (67%), followed by metastatic squamous cells carcinoma (14 cases, 15%). Conclusion: Fine needle aspiration cytology of lymphadenoathy is a useful tool in diagnosing metastatic lesions with good certainty.

A clinicoepidemiological study of 50 cases of cutaneous tuberculosis in a tertiary care teaching hospital in pokhara, Nepal.

Abstract: Background: Cutaneous tuberculosis (TB) is essentially an invasion of the skin by Mycobacterium tuberculosis, the same bacteria that causes pulmonary tuberculosis. Aim: This study was conducted to study the common types of cutaneous TB and to find the management pattern in a tertiary teaching hospital in Pokhara, Nepal. Materials and Methods: All the cases of cutaneous TB were biopsied and furthermore investigated by performing Mantoux test, sputum examination, fine needle aspiration cytology, chest X-ray and ELISA. Results: In this study, we found that tuberculosis verrucous cutis (48%) had a higher incidence than other types of cutaneous TB. More males were affected than were females (1.2:1). Commonly affected sites were the limb and the buttock (48%). The most commonly affected age group was 16-25 years (40%). All cases (except two) were more than 15 mm in size in the Mantoux test. The histopathological picture was typical in all except three cases. All patients were treated with antitubercular treatment as per the national guidelines. Conclusion: The most common type of cutaneous TB was tuberculosis verrucous cutis and the most commonly affected sites were the limb and the buttock. As cutaneous TB sometimes reflects the presence of pulmonary tuberculosis, its incidence should not be ignored.

Synchronous bony and soft tissue metastases from follicular carcinoma of the thyroid.

Abstract: Follicular carcinoma of the thyroid rarely manifests itself as a distant metastatic lesion, and, when present, is usually found in flat bones. A soft tissue metastasis is extremely rare, and synchronous metastases to the bone and soft tissue is not reported in the literature so far. We report such a case of a 42-yr-old male, who presented with a goiter, scalp and forearm soft tissue swellings, and, fine needle aspiration cytology of all these swellings revealed a follicular neoplasm. A wide excision of the forearm swelling was carried out and the histopathology was consistent with features of metastatic follicular carcinoma of the thyroid. The main stay of treatment is surgical resection of the primary tumor. The various modalities of treatment of metastasis is discussed with a review of literature.

A 14 Years Hospital Based Study on Clinical and Morphological Spectrum of Hydatid Disease

Abstract: Introduction: Hydatid disease is endemic in sheep and cattle-raising areas worldwide Its prevalence is high in Nepal The study was carried out to determine the clinical, radiological and pathological presentations of hydatid disease Methods: This was a retrospective study of all hydatid disease cases reported in Department of Pathology, from August 1996 to July 2010 All the clinical, radiological and pathological data were collected and collated Results: A total of 51 cases of hydatidosis were studied Patients presented with related symptoms in 47 cases, 9216% with CI (8478, 9954) and asymptomatic in four cases, 784% with CI (046, 1522) Involvement of liver and lung was found in 35 (6863%) cases and 10 (1961%) cases respectively Involvement of other organs like kidney, pelvis and broad ligament were seen in 6 of the cases Total 29 cases, 5686% with CI (432, 7046) had solitary cyst while rest of the cases had multiloculated cyst All cases had radiological correlation and histopathological confirmation Conclusions : Most cases presented with organ related vague symptoms, however it should be considered as a differential diagnosis especially in asymptomatic cases and cases with unusual sites Imaging studies is useful in preoperative diagnosis and postoperative histopathology is confirmatory A multicentric hospital based study will help to decrease the incidence _______________________________________________________________________________________ Keywords: echinoccocus; hydatid cyst; hydatidosis

Harrison's Principles of Internal Medicine

Abstract: The 11th edition of Harrison's Principles of Internal Medicine welcomes Anthony Fauci to its editorial staff, in addition to more than 85 new contributors. While the organization of the book is similar to previous editions, major emphasis has been placed on disorders that affect multiple organ systems. Important advances in genetics, immunology, and oncology are emphasized. Many chapters of the book have been rewritten and describe major advances in internal medicine. Subjects that received only a paragraph or two of attention in previous editions are now covered in entire chapters. Among the chapters that have been extensively revised are the chapters on infections in the compromised host, on skin rashes in infections, on many of the viral infections, including cytomegalovirus and Epstein-Barr virus, on sexually transmitted diseases, on diabetes mellitus, on disorders of bone and mineral metabolism, and on lymphadenopathy and splenomegaly. The major revisions in these chapters and many

Manson's Tropical Diseases

Abstract: The first edition of this reference work was published in 1898, and the last update was published in 1972. This current edition is written by six major contributors and contains either rewritten or new chapters, including one 29-page chapter entitled "Ophthalmology in the Tropics" by F. C. Rodger, MD. Not only is this material valuable to physicians in endemic areas, but it is also important for travelers to the tropics who may return home with these diseases. Most of the chapters discuss the following aspects of tropical disease: cause, transmission, immunology, epidemiology, geographical distribution, pathologic condition, clinical findings, and diagnosis (including laboratory findings, treatment, and prevention). Beside chapters on infections, there are chapters on disorders due to heat, nutritional diseases, and venoms and poisons, and appendices on protozoology, helminthology, entomology, and clinical pathologic conditions. Excellent illustrations of end-stage pathologic conditions are disconcerting. Ophthalmologists would be most interested in the discussion
