Clinicopathological characteristics of cutaneous lupus erythematosus patients in Bangladesh.

Introduction: Nearly all epidemiologic studies have involved patients with systemic lupus erythematosus (SLE). Few authors have investigated the characteristics of patients with cutaneous lupus erythematosus (CLE).

Aim: To describe the clinical and pathologic characteristics of a series of patients diagnosed with CLE.

Efficacy of oral methotrexate (MTX) monotherapy vs oral MTX plus narrowband ultraviolet light B phototherapy in palmoplantar psoriasis.

Palmoplantar psoriasis (PPP) is a chronic, inflammatory dermatosis of the palms and/or soles with significant morbidity. It is notoriously difficult to treat and unresponsive to traditional topical agents. We aim to compare the effect of oral methotrexate (MTX) monotherapy vs MTX plus narrowband ultraviolet light B (NB-UVB) in the treatment of recalcitrant PPP.

Leprosy profiles in post-elimination stage: a tertiary care hospital experience.

Background: Most countries that were previously highly endemic for leprosy have achieved elimination at the national level.

Objectives: To find out the pattern, prevalence, and trends of leprosy in the post-elimination stage.

Methods: A descriptive retrospective cross-sectional study was carried out using the registered records of patients attending the leprosy clinic in Chittagong Medical College Hospital between the periods 2001 and 2011.

Intraoperative pathology consultation: error, cause and impact.

Background: Correlation of intraoperative frozen section diagnosis with final diagnosis can be an important component of an institution's quality assurance process.

Methods: We performed a quality assurance review of 1207 frozen section diagnoses from 812 surgical cases performed in the Hamilton Regional Laboratory Medicine Programme during a 6-month period in 2007. We reviewed the frozen section and permanent slides from all potentially discordant cases using a multiheaded microscope to arrive at a consensus pertaining to the type and reason for error.

Transcranial microsurgical and endoscopic endonasal cavernous sinus (CS) anatomy: a cadaveric study.

Aims And Objectives: Even in the era of tremendous microneurosurgical and endoscopic development, the cavernous sinus (CS) is a challenging anatomical site for a neurosurgeon. Many transcranial and a few endoscopic cadaveric studies have been done to study the CS; probably none were undertaken to study its microsurgical and endoscopic anatomy side by side. In this cadaveric study we perform a side-by-side comparison of the microsurgical and endoscopic anatomy of the CS that can help neurosurgeons deal with CS lesions more efficiently.

Endoscopic endonasal transsphenoidal exposure of circle of Willis (CW); can it be applied in vascular neurosurgery in the near future? A cadaveric study of 26 cases.

Aim: Endonasal transsphenoidal approaches are getting rapidly popular in removing many midline skullbase lesions from crista galli to foramen magnum. For safe removal of these lesions, familiarity with endoscopic endonasal anatomy of circle of Willis is very important. Furthermore, for safe development of this approach in vascular neurosurgery in the near future, endoscopic endonasal exposure of circle of Willis is a fundamental step.

Experimental and trajectory study on the reaction of protonated methionine with electronically excited singlet molecular oxygen (a1Δg): reaction dynamics and collision energy effects.

The reaction of protonated methionine with the lowest electronically excited state of molecular oxygen O(2)(a(1)Δ(g)) was studied in a guided ion beam apparatus, including the measurement of reaction cross sections over a center-of-mass collision energy (E(col)) range of 0.1-2.0 eV.

White fiber dissection of brain; the internal capsule: a cadaveric study.

Aim: This study was done to study the three dimensional anatomy of internal capsule's white fibers completely by cadaveric dissection and its relation to basal ganglia and other related anatomical structures.

Material And Methods: Eight formalin fixed cerebral hemispheres were dissected for internal capsule under operating microscope. Klingler's technique of fiber dissection was adopted.

A very active cu-catalytic system for the synthesis of aryl, heteroaryl, and vinyl sulfides.

cis-1,2-Cyclohexanediol (L3) has been shown to be an efficient and versatile bidentate O-donor ligand that provides a highly active Cu-catalytic system. It was more effective than diols such as trans-1,2-cyclohexanediol or ethylene glycol. This commercially available cis-1,2-cyclohexanediol ligand facilitated the Cu-catalyzed cross-coupling reactions of alkyl, aryl, or heterocyclic thiols with either alkyl, aryl, heterocyclic, or substituted vinyl halides.

An Improved Process for the Synthesis of 4H-Imidazo[1,5-a][1,4]benzodiazepines.

The construction of CNS active imidazo[1,5-a][1,4]benzodiazepines has been improved in a one-pot annulation process.

Cutaneous tuberculosis--a study of 400 cases.

A prospective study was conducted on 400 cases having clinical manifestation of cutaneous tuberculosis from 1992 to 2001 in the department of Dermatology and Venereology, Dhaka Medical College Hospital (DMCH) and Bangabandhu Sheikh Mujib Medical University (BSMMU), formerly Institute of Postgraduate Medicine and Research, Dhaka, Bangladesh. The clinical diagnosis was confirmed by histopathological examination. Among 400 cases, 260 (65%) were males and 140 (35%) were females with a male to female ratio 1.
