Feline polycystic kidney disease (PKD) is an inherited disorder caused by the mutation of PKD1 gene that eventually lead to the development of chronic kidney disease. The latter condition causes hypertension and eventually progress into congestive heart failure. Feline parvovirus (FPV) is a highly contagious and often fatal disease infecting cats and other members of Felidae. An 8-month-old female domestic shorthair cat was presented with complaint of wound dehiscence a day after ovarian hysterectomy procedure. The wound at the suture site appeared necrotic, purulent with foul smell. The cat was found to have diarrhoea during the fixation of suture breakdown and, later, was tested positive with parvovirus infection. Complete blood count revealed anaemia, neutrophilia, lymphopenia and thrombocytosis. Biochemistry profiles showed hypoproteinaemia and elevated of urea and creatinine. The cat was hospitalised, and symptomatic treatments were given. During hospitalisation, the cat showed symptoms of polydipsia and polyuria and found dead 2 days later. Post-mortem findings demonstrated the cat had oral ulceration, thoracic effusion, fibrinopleuropneumonia, pericardial effusion, left ventricular hypertrophy and right ventricular dilation, chronic passive liver congestion, mesenteric lymphadenomegaly, intestinal haemorrhage, adrenomegaly and polycystic kidney. Histopathological evaluation revealed fibrinous pleuropneumonia, pulmonary atelectasis, emphysema and oedema, hypertrophic cardiomyopathy, hepatic necrosis, splenic necrosis, intestinal necrosis, renal necrosis and renal polycystic. Staphylococcus aureus and Escherichia coli were isolated from bronchus swab and intestinal segment, respectively. Polymerase chain reaction (PCR) revealed parvovirus infection. The cat was definitely diagnosed with polycystic kidney disease concurrent with parvoviral and secondary bacterial infections.

PMID: 15889560

All percutaneous tracheostomies performed in the general intensive care unit (ICU), Hospital Sultanah Aminah, Johor Bahru, Malaysia, from July 1999 to June 2002 were studied. The tracheostomies were performed as an elective bedside technique in the ICU. A total of 352 percutaneous tracheostomies were performed. Eighty-eight percent of the tracheostomies were completed within 15 minutes. The most common complication was bleeding which occurred in 52 patients (14.7%). The rest of the complications encountered were:- transient hypoxia twelve (3.4%), inability/ difficulty to insert tracheostomy tube eight (2.3%), false passage four (1.1%), transient hypotension two (0.6%), pneumothorax two (0.6%), peristomal infection two (0.6%), subcutaneous emphysema one (0.3%), cuff rupture one (0.3%), oesophageal cannulation one (0.3%), and granuloma formation one (0.3%). Conversion to conventional tracheostomies were performed on 7 patients (2%). There was one unfortunate death related to percutaneous tracheostomy. In conclusion, percutaneous dilational tracheostomy can be used safely to manage the airway of critically ill patients.

Inflammation and endothelial dysfunction are key components in atherogenesis. Should the status of these pro-atherogenesis factors be enhanced during prolonged confined space travel, specific countermeasures need to be instituted to prevent these processes to ensure safe outcome for astronauts during space expeditions. Six crew members were exposed to prolonged, confined isolation for 520 days. Standard exercise and diet regime were instituted throughout isolation phase. Age and gender-matched healthy, free living controls were recruited in parallel. Serial serum and whole blood were analysed for biomarkers of inflammation (hsCRP and IL-6) and endothelial activation (sICAM-1, sVCAM-1 and E-selectin). Flow-mediated dilatation (FMD) of the artery was performed following the standard protocols set by the International Brachial Artery Reactivity Task Force by trained personnel. There was decreased sVCAM-1 concentration in crew members compared to baseline. However, there was significant decrease in percentage dilatation from baseline in FMD of the brachial artery in the crew members. Percent change increment was observed in hsCRP while percent change reduction was seen in sVCAM-1. The enhanced inflammation and reduced endothelial function could possibly be attributed to the rigorous exercise instituted throughout the confinement period. Furthermore, possible haemoconcentration as a result of psychosocial stress and/ or exercise-induced physiological response could further explain elevations in hsCRP, and unlikely pathological. Furthermore, endothelial activation was attenuated during isolation, suggesting that the diet and exercise program instated throughout the period improved endothelial function.

OBJECTIVE: Eustachian tube dysfunction is a known complication following radiotherapy to the head and neck region. Unfortunately, treatment options are limited, with significant associated morbidity. Balloon Eustachian tube dilatation has been used successfully to treat Eustachian tube dysfunction; hence, this study aimed to determine the safety and efficacy of this method in treating Eustachian tube dysfunction in post-radiotherapy patients with nasopharyngeal carcinoma.
METHOD: This interventional cohort pilot study on patients with Eustachian tube dysfunction compared those with nasopharyngeal carcinoma to patients without. Outcome assessment was based on tympanometry type and Eustachian Tube Dysfunction Questionnaire score.
RESULTS: A total of 14 ears (12 patients) were tested. Only 14 per cent of the nasopharyngeal carcinoma cohort showed improvement, while 71 per cent of the non-nasopharyngeal carcinoma group were successfully treated. No significant adverse effect was reported in any patient during this study.
CONCLUSION: Balloon Eustachian tube dilatation was not shown to be beneficial for post-radiotherapy Eustachian tube dysfunction in nasopharyngeal carcinoma patients in the preliminary stages of this pilot study.

Oesophageal strictures often occur following esophagectomy which is performed for cases of oesophageal cancer. These patients require repeated dilation procedures. The aim of this study is to investigate the effects of dietary regimens, which are changed because of stenosis, caused by Helicobacter pylori (H. pylori). In this retrospective study, 28 patients who had operation for oesophageal cancer and underwent dilation due to development of stricture were studied. 30 female and 30 male patients who were admitted to the Gastroenterology Clinic with complaints of dyspepsia and did not receive treatment for the eradication of H. pylori were randomly selected and included in this study as a control group. Patients' histopathological records on the hemogram, biochemistry, and endoscopic biopsy were analysed. There were 26 H. pylori (+) cases (92.8 %) in the stenosis group consisting of 28 patients, and 37 H. pylori (+) cases (61.6%) in the control group consisting of 60 patients. These results were found to be statistically significant (P=0.003). The albumin level in the stenosis group was reported to be statistically low (P=0.002). The incidence of H. pylori was found to be significantly higher in patients with stenosis. We ascribed this outcome due to changes in dietary regimens. Our findings showed that the dietary regimens of all patients who underwent esophagectomy should be regulated during the postoperative period considering H. pylori. The relationship between H. pylori and stenosis was significant, there is a need for further research with a larger sample size to enrich the findings.

Tubular colonic duplication presenting in adults is rare and difficult to diagnose preoperatively. Only a few cases have been reported in the literature. We report a case of a 29-year-old lady presenting with a long history of chronic constipation, abdominal mass and repeated episodes of abdominal pain. The abdominal-pelvic computed tomography scan showed segmental bowel wall thickening thought to be small bowel, and dilatation with stasis of intraluminal content. The provisional diagnosis was small bowel duplication. She was scheduled for single port laparoscopic resection. However, a T-shaped tubular colonic duplication at sigmoid colon was found intraoperatively. Resection of the large T-shaped tubular colonic duplication containing multiple impacted large fecaloma and primary anastomosis was performed. There was no perioperative complication. We report, herein, the case of a T-shaped tubular colonic duplication at sigmoid colon in an adult who was successfully treated through mini-laparotomy assisted by single port laparoscopic surgery.
