1.Gastric Duplication Cyst in an Infant Presenting with Non-Bilious Vomiting
Malaysian Journal of Medical Sciences 2012;19(1):76-78
In an infant presenting with a mass in the abdomen and non-bilious vomiting, duplication cyst needs to be considered in the list of differential diagnoses. Gastric duplication cyst is an uncommon occurrence in children. Diagnosis is based on clinical findings and imaging features. Surgical excision is safe and offers a complete cure. The literature recommends excision even in asymptomatic cases due to isolated reports of malignancy arising in the duplication cyst in later life.

Fenofibrate is mainly used to reduce cholesterol level in patients at risk of cardiovascular disease. Thermal transition study with the help of differential scanning calorimetry (DSC) shows that the aforesaid active pharmaceutical ingredient (API) is a good glass former. Based on our DSC study, the molecular dynamics of this API has been carried out by broadband dielectric spectroscopy (BDS) covering wide temperature and frequency ranges. Dielectric measurements of amorphous fenofibrate were per-formed after its vitrification by fast cooling from a few degrees above the melting point (Tm ? 354.11 K) to deep glassy state. The sample does not show any crystallization tendency during cooling and reaches the glassy state. The temperature dependence of the structural relaxation has been fitted by single Vogel–Fulcher–Tamman (VFT) equation. From VFT fit, glass transition temperature (Tg) was estimated as 250.56 K and fragility (m) was determined as 94.02. This drug is classified as a fragile glass former. Deviations of experimental data from Kohlrausch–Williams–Watts (KWW) fits on high-frequency flank of α-peak indicate the presence of an excess wing in fenofibrate. Based on Ngai's coupling model, we identified the excess wing as true Johari–Goldstein (JG) process. Below the glass transition temperature one can clearly see a secondary relaxation (γ) with an activation energy of 32.67 kJ/mol.

Simultaneous fracture/dislocation of the thumb carpometacarpal (CMC) joint and dislocation of the metacarpophalangeal (MCP) joint is considered as a rare injury pattern. We report an unusual case of dorsal dislocation of MCP joint of the thumb associated with extraarticular fracture of the base of the first metacarpal in a 28-year-old man. The dislocation of MCP joint had been missed during initial presentation at a peripheral centre. The patient made an uneventful recovery following open reduction and fixation with 1.25 mm Kirschner wire of the MCP joint along with repair of the ulnar collateral ligament. This injury pattern has not been previously reported to the best of our knowledge in the English-language based medical literature.
