Split Tummy Exercise Program for Reducing Diastasis Recti in Postpartum Primigravidae: A Randomized Controlled Trial / 가정의학회지

Background@#Diastasis rectus abdominis (DRA) involves the separation of the midline abdominal muscles and linea alba and affects more than half of postpartum women. This study aimed to assess the effect of a split tummy exercise program (STEP) on DRA closure in postpartum mothers. @*Methods@#A randomized controlled trial was conducted from 2008 to 2020 at the Obstetrics and Gynaecology Clinic of the Universiti Kebangsaan Malaysia Medical Centre. Primigravida mothers diagnosed with DRA were selected and randomly assigned to the intervention (n=21) or control (n=20) group. The intervention group underwent a home-based STEP consisting of three phases of nine abdominal exercises. DRA size was assessed at baseline and at 8 weeks postpartum using two-dimensional ultrasound. @*Results@#The mean age of the participants was 28 years (standard deviation, 3.6), with the majority of Malay ethnicity (87.8%) and working mothers (78%). After 8 weeks, the intervention group showed a significant reduction in DRA size of up to 27% (mean difference, 6.17 mm; 95% confidence interval, 3.7–8.7; P<0.001). No significant intergroup DRA changes were observed after 8 weeks of follow-up. @*Conclusion@#Early postpartum screening for DRA should be advocated to allow early STEP intervention to ensure favorable outcomes. STEP intervention is an effective postnatal training program for managing DRA.

Sonographic nomogram of paediatric renal size in Pusat Perubatan Universiti Kebangsaan Malaysia (PPUKM)

@#Introduction: A person’s childhood is an important period of growth, and also one’s most vulnerable, as one can be exposed to various pathologies, for example those that could affect the growth of one’s kidney. Asians are physiologically different from Caucasians, and the nomogram renal size obtained from a Western population (mostly of Caucasians) is not be suitable for representing Asian children. As such a nomogram on paediatric renal size derived from Malaysia is needed. Methods: A total of 109 (64 males and 45 females) aged 0-12 in Pusat Perubatan Universiti Kebangsaan Malaysia (PPUKM) took part in this study. They underwent ultrasonography of both kidneys, and their demographic and anthropometric data were collected. The mean and standard deviations of the renal length and renal volume according to their age groups was calculated, and the final data was compared to the ones reported by Rosenbaum et al. (1984). Result: Body weight and Body Surface Area (BSA) of the children reported the strongest correlation with renal size. Significant differences were found between local and the data from Rosenbaum et al (1984). A nomogram on paediatric renal size based on children in PPUKM was then created. Discussion: Ultrasonography is regarded as the standard method for determining renal size. Body weight and BSA were both strongly correlated with renal size. It was shown that the widely used nomograms derived from data obtained from Caucasian was not suitable to represent the population of Malaysian children.

Five cases of iatrogenic cerebrospinal fluid (CSF) rhinorrhoea: Early management is crucial

Endoscopic sinus surgery (ESS) is a standard treatment forrhinosinusitis, which failed optimum medical therapy.Iatrogenic cerebrospinal fluid (CSF) rhinorrhoea can occurduring ESS warrants early repair of the leakage. Thecommon sites for CSF leakage are cribriform plate, foveaethmoidalis, and anterior ethmoid sinuses. We present fivecases of iatrogenic CSF rhinorrhoea due to ESS and itsmanagement.

Diagnostic challenge of Burkitt’s lymphoma at early age

A four-year-old Ibanese boy presented with subacute abdominal distension for two months duration. Ultrasound and computed tomography (CT) scan showed solid liver masses as well as bowel and intraperitoneal lesions. Initial diagnosis of intraperitoneal inflammatory process as in tuberculosis with non-liquefied liver abscess with differential diagnosis of neoplastic process was made. Liver biopsy and peritoneal fluid analysis revealed Burkitt’s lymphoma (BL). We aim to highlight the diagnostic challenge of BL in this young age group emphasizing on the ultrasound and CT features of intraabdominal BL. We would also want to stress the importance of early diagnosis of BL as it is known to be the most aggressive tumour within 24 hours yet to have good survival if early diagnosis was made.

Association of Cobb angle progression and neuraxial abnormality on MRI in asymptomatic Adolescent Idiopathic Scoliosis

Background: Detection of neuraxial abnormality in neurologically asymptomatic adolescent idiopathic scoliosis (AIS) is crucial prior to surgery. It can only be detected on magnetic resonance imaging (MRI), which was not routinely done in this group of patient. On the other hand, whole spine radiographs for measurement of Cobb angle have been routinely included during clinic follow-up. This study aimed to determine the correlation between Cobb angle progression and neuraxial abnormality finding on MRI in asymptomatic AIS. Methods: A retrospective study was conducted in the Orthopaedic department of a tertiary hospital. Patients with asymptomatic AIS aged 10-20 years who attended scoliosis clinic from year 2007 to 2010 was reviewed. Patients who had whole spine MRI and two vertebral radiographs at least one year apart were further selected. Statistical analysis was done to see the association between Cobb angle progression and neuraxial abnormality on MRI. Results: The mean age at first presentation was 14.4 years old. Female (n=249) to male (n=50) ratio was 5:1. Only 19 patients fulfilled the selection criteria. There were 5 patients (26.3%) who had neuraxial abnormalities. The mean curve progression was 7.05° (range from -5° to 28°). Patients with and without neuroaxial abnormality showed mean curve progression of 0.6º and 9.36° respectively. There was no significant association between Cobb angle progression and neuroaxial abnormality (p=1.000). Conclusion: Cobb angle progression is not a reliable indicator for predicting neuroaxial abnormality in patients with asymptomatic AIS. However, this study stressed the need to perform MRI prior to operation to document any associated neuraxial abnormality in clinically asymptomatic AIS patients.

Renal doppler assessment in differentiating obstructive from non-obstructive hydronephrosis in children

background: to determine the usefulness of Doppler ultrasound measurement of resistive index (RI) in differentiating obstructive from non-obstructive hydronephrosis in children. Methods: From August 2011 to November 2012, renal Doppler assessments of the intra-renal renal arteries were performed on 16 children (19 kidneys) with congenital hydronephrosis. the independent t-test was used to assess for significant difference in RI values between those with obstructive hydronephrosis (6 kidneys) and those with non-obstructive hydronephrosis (13 kidneys) as determined by dynamic renal scintigraphy. the assessor was blinded to the clinical findings and scintigraphy results. Results: RI was significantly different between obstructive and non-obstructive hydronephrosis. Obstructive hydronephrosis returned higher RI values, with mean RI of 0.78. Mean RI in non-obstructive hydronephrosis was 0.70, and the difference was significant (p <0.05). the sensitivity and specificity of Doppler ultrasound were 100% and 53% respectively. conclusion: Doppler ultrasound measurement of resistive index is useful in differentiating obstructive from nonobstructive hydronephrosis and provides an alternative non-ionizing investigation other than dynamic renal scintigraphy.

Contrast enhanced Voiding Urosonography (ce-VUS) as a radiation-free technique in the diagnosis of vesicoureteric reflux: Our early experience

Objective: Contrast-enhanced ultrasound has become increasingly utilised as an alternative imaging modality for the diagnosis of vesicoureteric reflux (VUR) in paediatric patients. The study objective is to evaluate the efficacy of contrast enhanced Voiding Urosonography (ce-VUS) compared with fluoroscopic micturating cystourethrography (MCU) in the detection of VUR. Methods: This prospective study was carried out between July 2011 and January 2013 on paediatric patients who underwent MCU. All consented patients would undergo ceVUS prior to MCU. We documented the epidemiology details, the number of Kidney-Ureter (K-U) unit studied, baseline renal and bladder sonogram, as well as presence of VUR on ce-VUR. The technique for ce-VUS was standardized using normal saline to fill the bladder prior to administration of SonoVue® (2.5 ml) to assess the kidney-ureter (K-U) unit. Dedicated contrast detection software was used to discern the presence of microbubbles in the pelvicaliceal system (PCS). The findings were then compared with MCU. Results: 27 paediatric patients were involved in the study [17 males (63%) and 10 females (37%)] involving 55 K-U units (one patient had a complete duplex system). MCU detected VUR in 10 K-U units while ce-VUS detected VUR in 8 out of the 10 K-U units. There were 2 false negative cases (both Grade 1) with ce-VUS. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of ce-VUS were 80%, 98%, 95%, 89% and 96%, respectively. Conclusion: ce-VUS is a sensitive and specific radiation-free alternative for the detection of VUR in the paediatric population.

Post-transarterial chemoembolization [TACE] biloma mimicking liver abscess: the role of different imaging modalities

Transarterial chemoembolization [TACE] is a recognized mode of treatment for patients with hepatocellular carcinoma. Complications related to the procedure such as liver failure, liver abscess, bile duct infection or even pulmonary embolism are known to cause morbidity and mortality in these patients. Biloma is a rare complication of TACE. Its incidence has been reported as between 0.9 - 2.1%. It is caused by injury to the arterial supply of bile duct, which then forms a bile-contained cavity either intra-hepatic or extra-hepatic in location. We report the case of a patient with recurrent hepatocellular carcinoma who was treated with TACE. He developed an infected biloma post-procedure. He had different imaging modalities that pointed to the diagnosis of biloma. He underwent appropriate management that led to resolution of the biloma

The Value of Pre-Operative Embolisation in Primary Inferior Vena Cava Paraganglioma

We report a case of a 13-year-old boy who complained of progressive abdominal distension and symptoms of anaemia. Radiological investigations revealed that the child had a hypervascular tumour of the inferior vena cava (IVC). Unfortunately, the child presented with acute lower gastrointestinal bleed soon after the investigation. He underwent an urgent pre-operative embolisation, aimed to reduce the tumour vascularity. A total resection of the tumour, right nephrectomy, and partial duodenal resection were done within 24 hours post-embolisation. The child was stable postoperatively. The histopathological examination revealed chromogranin-positive paraganglioma originating from the IVC. We highlight the radiological findings of rare primary IVC paraganglioma and the role of embolisation prior to surgical removal of the tumour.
