Research paper thumbnail of A rare case of community acquired Burkholderia cepacia infection presenting as pyopneumothorax in an immunocompetent individual

Asian Pacific journal of tropical biomedicine, 2012

It is a well known occurence in patients with cystic fibrosis and chronic granulomatous disease where it increases both morbidity and mortality. It has also been included in the list of organisms causing nosocomial infections in an immunocompetent host, most of them transmitted from the immunocompromised patient in which this organism harbors. We report a rare case of isolation of B. cepacia from the bronchoalveolar lavage fluid of an immunocompetent agriculturist who presented with productive cough and fever associated with a pyopneumothorax. This is the first case of community acquired infection reported in an immunocompetent person in India.

Children with these infections suffer from developmental impairments and other serious illnesses. This study aimed to measure the prevalence of geohelminth infection, infection intensity as well as the change in the intensity in children from Western Nepal over years.

Research paper thumbnail of Castleman's disease and superior vena cava thrombi: a rare presentation and a review of the literature

Mount Sinai Journal of Medicine a Journal of Translational and Personalized Medicine, Dec 1, 2001

It may present as asymptomatic involvement of one lymph node group or as a multicentric disease with systemic symptoms. Unlike localized disease, for which surgical excision is curative regardless of the histological type, multicentric disease often necessitates aggressive systemic therapy and portends a poor outcome. Superior vena caval thrombosis is an uncommon manifestation associated with Castleman's disease.

Conclusions: We describe the case of a massive aortic dissection presenting with stroke and lower gastrointestinal bleeding. Although a rare cause of acute mesenteric ischemia, aortic dissection should be included in the differential diagnosis of patients presenting with coexistent acute ischemia of the gut and other organ systems.

Research paper thumbnail of Bronchoscopic management of bronchopleural fistula with intrabronchial instillation of glue (N-butyl cyanoacrylate)

A series of 9 cases are reported where BPF was identified and managed with intrabronchial instillation of glue (N-butyl-cyanoacrylate) through a video bronchoscope. Out of 9 patients the BPF was successfully sealed in 8 cases (88.88%). In 1 patient of postpneumonectomy, the fistula was big, that is >8 mm who had a recurrence after the procedure. In one case of pyopneumothorax the leak reduced slowly and it took us 14 days to remove the intercostal drainage tube. Rest of the patients had a favorable outcome. No complications were observed in a follow-up of 6 months. In our opinion, it is a cost-effective, viable, and safe alternative compared with costly, time-consuming, and high-risk surgical procedures.

Research paper thumbnail of Removal of self expandable metallic airway stent: A rare case report

Their placement is considered to be permanent, with open surgery the only way to remove the stent, though there are few cases reports of their removal with the bronchoscope, but the complications after their removal are very high. In our patient, one and a half years after placement of SEMS, she developed cough with dyspnoea, video bronchoscopy showed stenosis above the level of stent with granulation tissue inside the stent, stent fracture in lower part and stent migration to right main bronchus, thus she had all conceivable complications of stent placement. The stent was removed with the help of rigid bronchoscope under general anaesthesia. She was discharged the following day. The case is being reported because it was unique in having all the possible complications of stent placement, and rare as we could take out the stent in Toto. Thirdly, the stent could be removed without any complication.

We present a case of uncontrolled hemoptysis managed with bronchial artery embolization. Bronchial artery embolization is an effective treatment for patients with hemoptysis. Serious complications are rare, but may occur if the arterial supply to other structures is compromised.
