We describe a case of recurrent uterine rupture at the site of a previous rupture. Our patient had a history of right interstitial pregnancy with spontaneous uterine fundal rupture at 18 weeks of pregnancy. During her subsequent pregnancy, she was monitored closely by a senior consultant obstetrician. The patient presented at 34 weeks with right hypochondriac pain. She was clinically stable and fetal monitoring showed no signs of fetal distress. Ultrasonography revealed protrusion of the intact amniotic membranes in the abdominal cavity at the uterine fundus. Uterine rupture is a rare but hazardous obstetric complication. High levels of caution should be exercised in patients with a history of prior uterine rupture, as they may present with atypical symptoms. Ultrasonography could provide valuable information in such cases where there is an elevated risk of uterine rupture at the previous rupture site. 相似文献

Primary malignant B-cell-type dural lymphoma is a rare subtype of primary central nervous system lymphoma (PCNSL). We herein report an unusual case of diffuse B-cell lymphoma that presents as a chronic subdural haematoma without extracranial involvement. The notable aspects of this case include the patient’s immunocompetence, a short clinical history of symptom onset, rapid neurological deterioration and a final diagnosis of high-grade PCNSL. This case highlights the challenges neurosurgeons face, especially in the emergency setting, when the disease manifests in varied presentations. 相似文献

A 68-year-old man presented with a six-month history of painless dysphagia, malnutrition, anorexia and vocal hoarseness. Signs of severe mitral regurgitation and preserved left atrial dimensions were discovered on transthoracic echocardiography. However, electrocardiography and chest radiography were strongly suggestive of left atrial enlargement. Further investigations confirmed extrinsic compression of the oesophagus, which caused the dysphagia. Computed tomography of the throrax revealed a giant left atrium that was not appreciated on echocardiography. Hoarseness was found to be caused by right recurrent laryngeal nerve palsy. Ortner''s syndrome, which describes the occurrence of vocal hoarseness due to a cardiopulmonary disease that results in the compression of the left recurrent laryngeal nerve, is usually associated with severe mitral stenosis. Herein, we report an unusual case of Ortner''s syndrome caused by a giant left atrium, which resulted from severe mitral regurgitation, causing extrinsic oesophageal compression and right recurrent laryngeal nerve palsy. Physicians should remain cognisant of cardiovascular disorders as uncommon causes of painless dysphagia or vocal hoarseness. 相似文献

Anticoagulation therapy is effective in preventing primary and secondary thromboembolic events due to atrial fibrillation. Warfarin, which was approved by the United States in 1954, was the only long-term oral anticoagulation therapy till the approval of dabigatran in 2010, and of rivaroxaban and other direct factor Xa inhibitors from 2011, forming a group known as novel oral anticoagulants (NOAC). NOAC have fewer food and drug interactions compared to warfarin; hence, the patient will require fewer clinic visits. However, the short half-life of NOAC means that twice-a-day dosing is needed and there is higher risk of a prothrombotic state when doses are missed. Other disadvantages are the lack of long-term data on NOAC, their high cost and the current lack of locally available antidotes. 相似文献

INTRODUCTION
Although heart failure (HF) management is available at primary and secondary care facilities in Malaysia, the optimisation of drug therapy is still suboptimal. Although pharmacists can help bridge the gap in optimising HF therapy, pharmacists in Malaysia currently do not manage and titrate HF pharmacotherapy. The aim of this study was to develop treatment algorithms and monitoring protocols for angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, beta-blockers and spironolactone based on extensive literature review for validation and utilisation by pharmacists involved in HF management.METHODS
A Delphi survey involving 32 panellists from private and government hospitals that provide cardiac services in Malaysia was conducted to obtain a consensus of opinion on the treatment protocols. The panellists completed two rounds of self-administered questionnaires to determine their level of agreement with all the components in the protocols.RESULTS
Consensus was achieved for most of the sections of the protocols for the four classes of drugs. The panellists’ opinions were taken into consideration when amending the components of the protocols that did not achieve consensus of opinion. Full consensus was achieved with the second survey conducted, enabling the finalisation of the drug titration protocols.CONCLUSION
The resulting validated HF titration protocols can be used as a guide for pharmacists when recommending the initiation and titration of HF drug therapy in daily clinical practice. Recommendations should be made in collaboration with the patient’s treating physician, with concomitant monitoring of the patient’s response to the drugs. 相似文献6.
Xanthogranulomas are the most common form of non-Langerhans cell histiocytosis. Both adult and childhood forms have been described. Adult cutaneous forms can present as solitary or multiple yellowish, orange-red or tan-hued papules. Herein, we present the case of a 28-year-old Chinese man with a skin-coloured nodule on his left nasal ala that persisted for several months. While initial impression was that of a fibrous papule of the nose, the results of an excision biopsy showed histological features corresponding to xanthogranuloma. This case demonstrates the condition''s myriad of dermatological presentations, and adds to the differential diagnoses of a cutaneous lesion found in the head and neck region. 相似文献

A 2-year-old girl presented with a one-day history of acute-onset bilateral painful, swollen eyes and a two-month history of loose stools. Physical examination revealed a right eyelid swelling with proptosis. Magnetic resonance imaging revealed a right orbital pseudotumour. The patient responded well to treatment with intravenous antibiotics and nonsteroidal anti-inflammatory drugs. However, three weeks later, she was readmitted with a vasculitic lesion over her left upper chest, with mucous-bloody diarrhoea. Histopathology confirmed the diagnosis of ulcerative colitis. The patient was treated with intravenous pulse methylprednisolone and sulphasalazine. Two weeks after discharge, she was readmitted for cutaneous vasculitis and worsening diarrhoea. The patient’s bowel and extraintestinal diseases resolved upon addition of infliximab to her treatment regimen. Her inflammatory markers also normalised. Azathioprine was subsequently added. Infliximab was discontinued after four doses and prednisolone was tapered off. The patient remained well without any flare-up after 24 months of follow-up. 相似文献

A 20-year-old man presented to our emergency department after he was hit by a forklift. He developed haemorrhagic shock from a subcutaneous haematoma in his left thigh and required monitoring in the surgical intensive care unit. He stabilised with aggressive fluid resuscitation with crystalloids and blood transfusion. The recovery was complicated by an infection of the subcutaneous haematoma. Following open drainage of the infected subcutaneous haematoma, he improved and was discharged. To the best of our knowledge, this is the first reported case of a subcutaneous haematoma causing haemorrhagic shock. 相似文献

Cerebellitis is a rarely encountered complication of isoniazid therapy. Its occurrence is usually associated with concomitant renal disease and haemodialysis. Herein, we report the case of a patient with this complication who presented with isolated bilateral symmetrical dentate nucleus T2 hyperintensities on magnetic resonance imaging. Isoniazid neurotoxicity has never been reported to cause bilateral dentate hyperintensities, for which the differentials are few and include metronidazole toxicity. 相似文献

Primary cardiac neoplasms are very rare as compared to metastatic tumors; 70% to 80% of them are benign myxomas. Myxomas are polypoid, round, or oval. They are gelatinous with a smooth or lobulated surface, usually white, yellowish, or brown. We report a case of left atrial myxoma with approximate cystis in morphous. 相似文献

We report a case of atypical pityriasis rosea in a 24-year-old Malay man. He presented with an 11-month history of three recurrent and persistent episodes of pityriasis rosea associated with oral ulcers. The first episode lasted for one month and recurred within 14 days. The second episode lasted for three months and recurred within nine days. The third episode lasted for seven months. Although all three episodes were not preceded by any prodromal symptoms, a herald patch was noted on three different sites (the left iliac fossa, abdomen and chest) on each successive episode. Recurrent pityriasis rosea and its association with oral ulcers, although quite uncommon, have been reported in the literature. However, reports of multiple recurrences, with prolonged duration of each episode and very short remissions in between, have not been made. To the best of our knowledge, this is the first report of such unique presentation. 相似文献

INTRODUCTION
Due to lifelong immunosuppression, renal transplant recipients (RTRs) are at risk of infectious complications such as pneumonia. Severe pneumonia results in respiratory failure and is life-threatening. We aimed to examine the influence of immunosuppressant dose reduction on RTRs with bacterial pneumonia and respiratory failure.METHODS
From January 2001 to January 2011, 33 of 1,146 RTRs at a single centre developed bacterial pneumonia with respiratory failure. All patients were treated using mechanical ventilation and aggressive therapies in the intensive care unit.RESULTS
Average time from kidney transplantation to pneumonia with respiratory failure was 6.8 years. In-hospital mortality rate was 45.5% despite intensive care and aggressive therapies. Logistic regression analysis indicated that a high serum creatinine level at the time of admission to the intensive care unit (odds ratio 1.77 per mg/dL, 95% confidence interval 1.01–3.09; p = 0.045) was a mortality determinant. Out of the 33 patients, immunosuppressive agents were reduced in 17 (51.5%). We found that although immunosuppressant dose reduction tended to improve in-hospital mortality, this was not statistically significant. Nevertheless, during a mean follow-up period of two years, none of the survivors (n = 18) developed acute rejection or allograft necrosis.CONCLUSION
In RTRs with bacterial pneumonia and respiratory failure, higher serum creatinine levels were a mortality determinant. Although temporary immunosuppressant dose reduction might not reduce mortality, it was associated with a minimal risk of acute rejection during the two-year follow-up. Our results suggest that early immunosuppressant reduction in RTRs with severe pneumonia of indeterminate microbiology may be safe even when pathogens are bacterial in nature. 相似文献13.

Venlafaxine, a serotonin and norepinephrine reuptake inhibitor, is increasingly used in pregnant women with pre-existing depression who require continued treatment. However, its in utero effects on the developing fetus are not clear. Herein, we report the unusual presentation of venlafaxine withdrawal in a female preterm baby of 29 weeks gestation, who presented with myoclonic seizures on her second day of life. The seizures were confirmed using amplitude-integrated electroencephalography, and other possible causes of neonatal seizures were excluded. The baby responded to treatment with phenobarbitone and phenytoin. Magnetic resonance imaging of her brain was unremarkable at corrected gestational age of 39 weeks and 2 days. On follow-up at the corrected age of five months, she was well and developing normally with no further seizures. To the best of our knowledge, this is the first report of seizures in a preterm baby resulting from maternal venlafaxine use. 相似文献

INTRODUCTION
Clinical practice guidelines recommend dietary sodium restriction in chronic kidney disease (CKD) patients. Compliance with this recommendation in a multiethnic Asian population is not clear. This study assessed the urinary sodium excretion profile of a multiethnic Asian population to estimate the population’s dietary sodium intake.METHODS
Data on the urinary sodium excretion of 335 participants were obtained from the Asian Kidney Disease Study and Singapore Kidney Function Study. Standard statistical tests and linear regression were used to assess the association between various continuous variables and sodium excretion.RESULTS
Our study cohort consisted of 335 participants (232 with CKD, 103 healthy) – 51.0% were male; 38.5% were Chinese, 29.6% were Malay, 23.6% were Indian; and 57.3% were hypertensive. The mean age was 53.5 ± 15.1 years and mean urinary sodium excretion was 124.9 ± 68.3 mmol/day. The mean blood pressure of the healthy participants was lower than that of the patients with CKD (p < 0.001). Patients with CKD stages 1–3 excreted an average of > 100 mmol sodium/day. Overall, 40.1% patients with CKD excreted < 100 mmol sodium/day. Indians had higher urinary sodium excretion than the Chinese (p = 0.016) and Malays (p = 0.002). The distribution of urinary sodium excretion in the healthy participants (37.9% excreted < 100 mmol sodium/day) was similar to that seen in the patients with CKD.CONCLUSION
Although patients with CKD stages 4–5 achieved sodium restriction, healthy persons and patients with early-stage CKD need to increase their efforts in reducing their sodium intake, especially for patients of Indian ethnicity. 相似文献15.
Acute kidney injury (AKI) and chronic kidney disease (CKD) are major health problems. Urinary biomarkers have both diagnostic and prognostic utility in AKI and CKD. However, how biomarker excretion rates should be reported, especially whether they should be normalised to urinary creatinine concentration (uCr), is controversial. Some studies suggest that normalisation to uCr may be inappropriate at times, as urinary creatinine excretion rate may vary greatly, depending on the situation. Notably, recent studies suggest that while normalisation of values to UCr may be valid for the evaluation of CKD and prediction of AKI sequelae and occurrences, it could be inappropriate for the diagnosis of AKI, or in the presence of certain acute kidney disease states. 相似文献

Ketamine is a short-acting anaesthetic agent that has gained popularity as a ‘club drug’ due to its hallucinogenic effects. Substance abuse should be considered in young adult patients who present with severe debilitating symptoms such as lower urinary tract symptoms, even though the use of controlled substances is rare in Singapore. Although the natural history of disease varies from person to person, a relationship between symptom severity and frequency/dosage of abuse has been established. It is important to be aware of this condition and have a high degree of clinical suspicion to enable early diagnosis and immediate initiation of multidisciplinary and holistic treatment. A delayed diagnosis can lead to irreversible pathological changes and increased morbidity among ketamine abusers. 相似文献

In a patient who had a calcified left atrial myxoma resected, recurrence developed 31 months later. Although complete radical resection of the recurrent tumour presented a special problem, the patient survived the second operation. The tumour recurred again and the patient had two episodes of cerebral embolism 1 1/2 and 2 years later, respectively, and died 3 1/2 years after the second operation. The erythrocyte sedimentation rate correlated with the size of the tumor, and the recurrent tumour seemed to grow more rapidly than the primary tumour. Experience with this case and a review of the nine reported cases of recurrent left atrial myxoma suggest that a radical approach is necessary at the primary operation. 相似文献

Port-site metastasis (PSM) is often encountered during laparoscopic surgery in patients with malignancy. We report a 45-year-old woman who presented with a single PSM from papillary adenocarcinoma after undergoing laparoscopic cholecystectomy for calculus cholecystitis. Post cholecystectomy, a diagnosis of chronic cholecystitis was confirmed on histopathology. The patient presented with a mass at the site of epigastric port 28 months after surgery. PSM was suspected on clinical examination, which was supported by findings on computed tomography and further confirmed by fine-needle aspiration cytology of the lump. The patient underwent surgical clearance of the mass, and histopathological examination proved the lesion to be papillary adenocarcinoma. The site of the primary tumour was not detected even after thorough examination. Based on the histopathology report following local surgical clearance, the patient was started on chemotherapy. This case is unusualbecause of the long delay prior to the presentation of PSM and the unknown primary malignancy. 相似文献

A patient with non-ischaemic cardiomyopathy, and pre-existing atypical atrial flutter and left bundle branch block, developed broad complex tachycardia. In this unique and uncommon case of double tachycardia, we discuss the diagnostic approach of ventricular tachycardia in patients with broad complex tachycardia, and the use of different contemporary algorithms to help diagnose ventricular tachycardia and differentiate it from supraventricular tachycardia with aberrant conduction. 相似文献
