If there is spine muscle stiffness, the patient's knees may draw up when you try to bend the neck forward. If you are in doubt for example, (the neck does bend, but seems stiff or the patient complains of even mild pain), consider this to be stiffness and refer the patient. Summ-ry: 1. Have the patient lie on his back with one hand behind his head which you support with your hand. 2. Gently try Lo bend the neck, bringing patient's chin to his chest. 3. If tue ;ueck will not bend, feels stiff, causes pain, or the knees bend up, there is neck stiffness. 2.

In a quiet baby, the fontanelle feels like a soft, diamond-shaped indentation. When a healthy baby cries or coughs, the anterior fontaneile bulges, so the exain must be done when the baby is quiet. When a baby has meningitis, a bulging fontanelle that feels full and tense may be present. (See Figure CD 2) If the soft spot is SWOLLEN, >1 . thle baby ­ may have MENINGITIS Figurec CD 2 Summary: 1.

The difficulty arises when the presentation of the patient is unusual. Case presentation: In this case report we present a case of a 22-year-old Tamang man, from the Terai region of Nepal, with a clinical presentation of fever, malaise, and arthralgia for the past 2 weeks with hepatosplenomegaly and bilateral cervical, axillary, and inguinal lymphadenopathy. Features of chronic inflammation with elevated erythrocyte sedimentation rate of 90 mm/hour and liver enzymes were noted. With no specific investigative findings, a diagnosis of Still’s disease was made and he was given prednisolone. On tapering the medication, after 2 weeks, the lymphadenopathy and fever reappeared. On biopsy of a lymph node, diagnosis of possible tuberculosis was made. On that basis anti-tuberculosis treatment category I was started. During his hospital stay, our patient developed nodular skin rashes on his shoulder, back, and face. The biopsy of a skin lesion showed erythema nodosum leprosum and he was diagnosed as having lepromatous leprosy with erythema nodosum leprosum; he was treated with anti-leprosy medication. Conclusion: An unusual presentations of leprosy may delay its prompt diagnosis and treatment; thus, increasing morbidity and mortality.

It can be a challenging differential diagnosis in dermatology practice due to several overlapping features with rheumatologic disorders. Patients with leprosy can develop reactive states as a result of immune complex-mediated inflammatory processes, leading to the appearance of additional cutaneous lesions that may further complicate the clinical picture. We describe a case of a woman presenting with a long history of a recurrent bullous rash with chronic ulcers, with an evolution of vasculitic diagnoses, who was later determined to have lepromatous leprosy with reactive erythema nodosum leprosum (ENL).

ABSTRACT Leprosy a major global health problem, especially in the developing world, is an infectious disease caused by Mycobacterium leprae. Leprosy has a predilection to with cooler areas of the body. Lepromatous leprosy presents with varied manifestations like nodules, cervical lymphadenitis, hyperpigmented patches and other presentations which can mimic various other diseases and pose a diagnostic challenge in endemic areas. We report a case presenting with nodular infiltration of the nose mimicking rhinophyma who presented with faint reddish swelling over the nose which progressed to nodular infiltration. There was bilateral symmetrical thickening of nerves following which diagnosis was confirmed by slit skin smear and the patient was started on multibacillary multidrug therapy.

Mycobacterium leprae, the causative agent of leprosy, presents tropism for cells of the reticuloendothelial and peripheral nervous system. Current multidrug therapy consists of clofazimine, dapsone and rifampicin. Despite significant improvements in leprosy treatment, in most programs, successful completion of the therapy is still sub-optimal. Drug resistance has emerged in some countries. This review discusses the status of leprosy disease worldwide, providing information regarding infectious agents, clinical manifestations, diagnosis, actual treatment and future perspectives and strategies on targets for an efficient targeted delivery therapy.

Corresponding Author: Velpula Nagesh Kumar Received: 14/07/2016 Revised: 10/08/2016 Accepted: 11/08/2016 ABSTRACT Granulomatous inflammation is a type of chronic inflammation that has distinctive pattern of presentation with wide etiology and can involve any organ. Pathologists come across this lesion frequently and through knowledge of granulomatous lesions are very much essential to discriminate them from other lesions in the skin as they closely mimic each other. The aim of the present study is know the types of dermal granulomas, their prevalence, age and sex distribution, modes of presentation and histopathological spectrum. This prospective study was undertaken at Osmania General Hospital, Hyderabad from June 2012 to May 2014. A total of 620 skin biopsies were received at the Department of Pathology, histopathological sections of all the cases were critically analyzed and were classified on a “pattern based” approach according to Rabinowitz and Zaim et al. 172 cases were categorized histopathologically as granulomatous dermatoses. Granulomatous dermatoses were more common in males and the peak age of incidence was in 3rd decade. Incidence of Granulomatous dermatoses was 27.7% which was comparable with available literature. In the present study we found that Infections form an important cause of granulomatous dermatoses with majority of cases being leprosy followed by cutaneous tuberculosis and foreign body granulomas.
