Prevalence and predictors of low bone mineral density in treatment-naive HIV-infected patients and its correlation with CD4 cell counts.

Objective: HIV virtually affects every organ system of the body. The skeletal system is no exception, and antiretroviral therapy (ART) has been implicated in bone diseases. However, not many studies have been done to evaluate bone disease in treatment (ART) naive HIV-infected patients, and hence, the present study was executed.

A prospective study of anti-mullerian hormone and other ovarian and adrenal hormones in adult female acne.

Polycystic ovarian syndrome (PCOS) diagnosis in adult female acne (AFA) is tough owing to unreliable ultrasonography in virgins or obese females and inconsistent hyperandrogenemia. We analyzed hormones in AFA and established a diagnostic cut-off value of anti-mullerian hormone (AMH) for PCOS. Female acne patients aged ≥25 years were assessed with total testosterone (TT), sex hormone binding globulin (SHBG), free androgen index (FAI), AMH, 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulfate (DHEAS), follicle stimulating hormone (FSH), and luteinizing hormone (LH).

A Prospective Study Examining Trigger Factors and Hormonal Abnormalities in Adult Female Acne.

Background: Numerous triggers have been implicated in adult female acne including endogenous (hormonal dysfunction and genetic predisposition) and exogenous causes (drugs, cosmetics, sunscreens, stress, and smoking).

Aims: To evaluate the role of various trigger factors in adult female acne and to analyze the androgenic hormone pattern including anti-Mullerian hormone (AMH) in these patients.

Materials And Methods: Patients having acne of age ≥25 years were analyzed using a pre devised proforma to elicit trigger factors while the severity was graded using the Global Acne Grading System (GAGS).

A study comparing the clinical and hormonal profile of late onset and persistent acne in adult females.

Background: Adult acne has been classified into two major subtypes: "persistent acne" and "late onset acne". A surrogate marker of hyperandrogenism (HA) in adult female acne is the presence of clinical signs of HA and biochemical hyperandrogenemia. We compared the clinical and hormonal profiles of the two acne subtypes and evaluated the likely source of androgen excess - ovarian or adrenal.

A prospective study examining isolated acne and acne with hyperandrogenic signs in adult females.

Background: Adult female acne (AFA) occurs beyond 25 years of age and can present either as isolated acne or with hyperandrogenic signs.

Methods: 120 females aged ≥ 25 years were evaluated for acne, hirsutism and androgenetic alopecia. Hormonal assessment included total testosterone (TT), sex hormone binding globulin (SHBG), free androgen index (FAI), Anti Mullerian Hormone (AMH), 17-hydroxyprogesterone (17-OHP), dehydroepiandrosterone sulfate (DHEAS), follicle stimulating hormone (FSH), luteinizing hormone (LH), thyroid stimulating hormone (TSH) and prolactin.

Microcystic lymphatic malformation in a child and his mother.

A 3-year-old boy presented to us with swelling of the right upper lip and the surrounding perioral area with the multiple clear fluid-filled grouped vesicles on the mucosal surface. The patient's mother had a similar swelling located at the same anatomic location extending to the cheek and the ala of nose on the same side. Magnetic resonance imaging and histopathological examination were suggestive of microcystic lymphatic malformation (LM) in both mother and child.

Neonatal Hypoxic-ischemic Encephalopathy: A Radiological Review.

Neonatal hypoxic-ischemic encephalopathy (HIE) is a devastating condition that may result in death or severe neurologic deficits in children. Neuroimaging with cranial ultrasound (US), computed tomography and magnetic resonance imaging are valuable tools in the workup of patients with HIE. The pattern of brain injury depends on the severity and duration of hypoxia and degree of brain maturation.

Central Nervous System Tuberculosis: An Imaging Perspective.

The increasing prevalence of tuberculosis in both immunocompetent and immunocompromised individuals in recent years makes the disease a topic of universal concern. It has insidious onset and can affect virtually any organ system in the body, including the central nervous system (CNS). CNS tuberculosis (TB) is becoming more and more complex and atypical with onset of multidrug-resistant TB.

Zinner syndrome-a rare developmental anomaly of the mesonephric duct diagnosed on magnetic resonance imaging.

Developmental anomalies of the urogenital tract are rare but often encountered. Zinner's syndrome is a rare congenital abnormality of mesonephric (Wolffian) duct consisting of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction due to developmental arrest in early embryogenesis affecting the caudal end of Mullerian duct and only approximately a 100 cases have been reported so far. Radiologic modalities such as intravenous pyelography, ultrasonography, vasovesiculography, contrast enhanced computed tomography, and magnetic resonance imaging are all helpful in diagnosis of this unusual entity.

Spectrum of Radiological Manifestations in Lymphoproliferative Malignancies with Unusual Extra Nodal Soft Tissue Involvement.

Lymphoproliferative malignancies constitute a wide spectrum of haematological malignancies and their prevalence is widely increasing. Non-Hodgkin lymphomas and Hodgkin disease, frequently involve extranodal soft tissue structures in the head and neck, thorax and abdomen. These malignancies may involve virtually any type of soft tissues to any extent; hence many different imaging manifestations are possible which may mimic other disorders.

Imaging in Rare and Atypical Sinonasal Masses: An Interesting Case Series.

Sinonasal tumours present a myriad of radiographic findings. While many of these tumours have been well described with regard to their typical sites of origin, age group and radiological appearance we have come across lesions in our daily practice which are exceedingly rare with regard to site of origin in sinonasal cavity. The radiological appearances of 4 such rare and unusual tumours arising in sinonasal region evaluated by cross sectional imaging (CT/MRI) have been illustrated in this article with a purpose to review the radio-pathological correlation of these tumours and to explain the utility of cross-sectional imaging CT and MRI in exploring diagnostic clues.

Magnetic Resonance Imaging of Brain in Evaluation of Floppy Children: A Case Series.

Objective Hypotonia is a common clinical entity well recognized in pediatric age group, which demands experienced clinical assessment and an extensive array of investigations to establish the underlying disease process. Neuroimaging comes as great help in diagnosing the disease process in rare cases of central hypotonia due to structural malformations of brain and metabolic disorders and should always be included as an important investigation in the assessment of a floppy child. In this article, we discuss the MRI features of eight cases of central and two cases of combined hypotonia and the importance of neuroimaging in understanding the underlying disease in a hypotonic child.

Radiographic patterns of soft tissue calcinosis in juvenile dermatomyositis and its clinical implications.

Juvenile Dermatomyositis (JDM) is a rare autoimmune inflammatory disease of muscles affecting children and adolescents with soft tissue calcification and varying systemic involvement. Though diagnosis is primarily by clinical, biochemical and histopathological tests, Imaging has unique significance from characterizing the calcinosis, detecting early changes in muscle in active phase of the disease, diagnosing potential complications,rule out other important differentials, guide biopsies ,and assessing the progress on follow up. Four distinct patterns of calcinosis have been described in relation to dermatomyositis which need to be differentiated from other aetiologies of soft tissue calcification and myopathies.
