Multiple Skin Abscesses and Myofibrosis of Bilateral Lower Limbs Following Repeated Intramuscular Injection of Pentazocine with Concomitant Tuberculous Infection.

Introduction: Prescription drug abuse is a major health problem across the globe. Various complications associated with repeated injection of pentazocine are reported in the literature, including skin fibrosis, skin abscesses and ulceration, abnormal skin pigmentation and fibrous myopathy.

Case Report: We present a case of 48 year male with history of pentazocine abuse.

Rare case of primary inferior vena cava leiomyosarcoma on F-18 fluorodeoxyglucose positron emission tomography-computed tomography scan: Differentiation from nontumor thrombus in a background of procoagulant state.

We report a rare case of leiomyosarcoma of the inferior vena cava (IVC) in which F-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography-computed tomography (PET-CT) scan provided vital evidence, which led to its diagnosis, in a background of procoagulant state of the patient, where previous ultrasound-Doppler and echocardiography studies were nonspecific and revealed bilateral lower limb deep vein thrombosis with thrombus in IVC. The whole body F-18 FDG PET-CT scan was done in view of no significant improvement in clinical status of the patient over few months in spite of appropriate medical management. FDG PET-CT scan revealed high grade uptake in a large mass lesion occupying the right atrium, extending superiorly into terminal superior vena cava, inferiorly into dilated IVC and probably into hepatic veins.

Nail cosmetics.

The nail as an anatomic structure protects the terminal phalanx of the digit from injury. Historically, it has served as a tool for protection and for survival. As civilizations developed, it attained the additional function of adornment.

Vulvar ulcer as a presentation of systemic Langerhans cell histiocytosis.

We report a 38-year-old housewife with systemic Langerhans cell histiocytosis (LCH) presenting as a chronic vulvar and peri-anal ulcer. She had systemic involvement in the form of diabetes insipidus and bone "hot-spots". She responded favorably to etoposide, 6-mercaptopurine, and systemic steroids, and has been in remission since 10 years.

Dedicated decontamination: A necessity to prevent cross contamination in high throughput mycobacteriology laboratories.

Unlabelled: Unrecognized cross-contamination has been known to occur in laboratories frequently, especially with sensitive recovery system like BACTEC 460 TB. In March 2001, we investigated a pseudo-outbreak of Mycobacterium tuberculosis isolates in three smear negative clinical specimens and would like to present our experience in this communication.

Methods: All suspected cases were confirmed by checking the drug susceptibility and DNA fingerprints using spoligotyping as well as restriction fragment length polymorphism.

Paget's disease of the bone: a report of three cases.

Paget's disease is uncommon in Asians. We present 3 patients with varying manifestations. A 50 years old lady was detected to have raised alkaline phosphatase at a routine health check-up.
