Three cases of progressive dyspnoea in young female adults due to pulmonary lymphangitic carcinomatosis are reported. The underlying primary neoplasm was gastric carcinoma in all 3 cases. The diagnosis was not suspected in 2 patients because of their young age.
Helicobacter pylori strains secrete a vacuolating cytotoxin (VacA), plays an important role for the development of peptic ulcer disease and gastro-duodenal diseases. vacA gene is responsible to regulate the activity of the vacuolating cytotoxin. The objective of this study was molecular detection of vacA gene and observes the vacuolating activity on human gastric adenocarcinoma (AGS) cells.
We report a case of visceral pentastomiasis caused by Armillifer moniliformis in a 70-year-old aboriginal farmer from rural Malaysian Borneo. The patient complained of upper abdominal pain, jaundice, and loss of weight. Radiological investigations and subsequent histopathological examination revealed an adenocarcinoma of the pancreas with an adjacent liver nodule containing a nymph of A. moniliformis. This report constitutes the first documented human pentastomid infection in the whole of Malaysia after nearly 40 years, and it is the third description from Malaysian Borneo. Cases of human and animal pentastomiasis in Malaysia are discussed.
Entero-cutaneous fistula resulting from a locally invasive large bowel carcinoma is a difficult surgical challenge. En-bloc resection of the involved organs and the entero-cutaneous fistula tract with a healthy tissue margin will result in a composite abdominal wall defect that requires closure. Reconstructive surgical options include primary closure, components separation and the use of local, regional or free flaps with or without prosthetic mesh. We report a case of an abdominal enterocutaneous fistula secondary to a locally invasive sigmoid carcinoma, which was reconstructed with a pedicled antero-lateral thigh perforator (ALT) flap. To our knowledge, this is the first case of a malignant entero-cutaneous fistula, which was reconstructed with an ALT flap.
OBJECTIVE:
To describe and provide audiovisual documentation of a syndrome of polymyoclonus, laryngospasm, and cerebellar ataxia associated with adenocarcinoma and multiple neural cation channel autoantibodies.
DESIGN:
Case report with video.
SETTING:
University hospitals. Patient A 69-year-old woman presented with subacute onset of whole-body tremulousness and laryngospasm attributed to gastroesophageal reflux.
RESULTS:
Further evaluation revealed polymyoclonus, cerebellar ataxia, and laryngospasm suspicious of an underlying malignant neoplasm. Surface electromyography of multiple limb muscles confirmed the presence of polymyoclonus. The patient was seropositive for P/Q-type voltage-gated calcium channel antibody; subsequently, whole-body fluorine 18 fluorodeoxyglucose positron emission tomography and cervical lymph node biopsy revealed widespread metastatic adenocarcinoma. Follow-up serologic evaluation revealed calcium channel antibodies (P/Q type and N type) and potassium channel antibody.
CONCLUSIONS:
We highlight the importance of recognizing polymyoclonus. To our knowledge, this is also the first description of a syndrome of polymyoclonus, laryngospasm, and ataxia associated with adenocarcinoma and these cation channel antibodies.
