d-Transposition of the great arteries in a 12-year-old child: is arterial switch still an option?

Arterial switch surgery for d-transposition of great arteries is usually performed in the first 2 weeks of life before the left ventricle regresses. The arterial switch surgery that helps achieve anatomic and physiologic correction of this condition has better long-term outcomes than other surgical approaches. The procedure may still be attempted at an older age where the left ventricle has not regressed. We report a rare case of a 12-year-old child with d-transposition of great arteries, a remote muscular ventricular septal defect and isolated valvar pulmonic stenosis, which was corrected by an arterial switch surgery.

Greater Arch Injuries

Dislocations and fracture dislocations of carpal bones are uncommon injuries which invariably poses challenges in the management. Perilunate fracture dislocations are the combination of ligamentous and osseous injury that involve the “greater arc” of the perilunate associated instability. Despite their severity, these injuries often go unrecognized in the emergency department leading to delayed diagnosis and treatment. A Prospective study was done from June 2008 to December 2013 in 15 cases of complex wrist injuries which included of greater arch injuries, perilunate fracture dislocation and one dorsal dislocation of Scaphoid. 10 cases of perilunate fracture dislocation underwent open reduction and internal fixation with Herbert screw and k-wire, 4 cases of greater arch injury underwent closed reduction and kwire fixation and one case of neglected dorsal dislocation underwent proximal row carpectomy. One patient had Sudecks osteodystrophy 1 had Scaphoid nonunion and 6 had median nerve compression. Overall outcome according to Mayo wrist score was 53 % excellent, 33 % good and 14 % fair. Greater arch injuries are difficult to treat because injuries to many ligaments are involved and failure to recognize early leads to persistent pain, disability and early onset of arthritis. Prompt recognition requires CT scan and MRI. Management requires reduction and multiple K-Wiring according to merits of the case.     

Trypsin inhibitory effect of wedelolactone and demethylwedelolactone

Wedelolactone (WL) and demethylwedelolactone (DWL) isolated from Eclipta alba were tested in the trypsin inhibition bioassay (in vitro). Both compounds showed potent activity. IC(50) values of WL and DWL were found to be 2.9 and 3.0 microg/mL respectively.     

Percutaneous Device Closure of a Bifurcated Inferior Vena Cava and Completion of the Kawashima Procedure for the ��Difficult�� Univentricular Heart

Azygos continuation of inferior venacava (IVC) is well known in association with interrupted IVC. We report azygos connection of uninterrupted IVC in a young child with complex univentricular heart. This peculiar anatomy was made suitable for univentricular repair by combining percutaneous device closure of prehepatic right limb of IVC and bidirectional Glenn shunt. The azygos vein acted as a conduit for IVC flow to superior venacava as in Kawashima’s operation. This case highlights a rare IVC morphology. Also this innovative strategy allowed simple solution to a challenging problem and is first time described in the literature.     

Actinomycetoma: dramatic response to modified two-step regimen

Mycetoma is a chronic granulomatous infection of the subcutaneous tissue caused by fungi or fungus-like bacteria. The infection eventually spreads to bone resulting in significant morbidity. Rarely, viscera may be involved through contiguous spread. It is common in tropical countries like India, though disease is worldwide in distribution. A 22-year-old male patient, a farmer by occupation, presented with multiple discharging sinuses over the left chest wall, shoulder, upper arm, and adjacent neck of eight months duration. A diagnosis of actinomycetoma was made based on clinical and histopathological features as culture was negative for both fungus and bacteria. The patient was treated with a modified two-step regimen. It consisted of an intensive phase with intravenous gentamicin 80 mg 12th hourly and cotrimoxazole 320/1600 mg twice daily orally for four weeks. This was followed by a maintenance phase with oral cotrimoxazole and doxycycline 100 mg twice daily. Patient showed excellent response with healing of all sinuses after two months of therapy. Involvement of covered parts of the body such as chest wall and shoulders is common in actinomycetoma compared to eumycetoma. Early institution of long-term combination therapy with antimicrobials results in excellent outcome.
