Catheter knotting is a rare complication of bladder catheterisation. Retention of catheter parts resulting in calculus formation is even rarer. We report a case of a vesical calculus formed over a broken and retained supra-pubic catheter which to the best of our knowledge has yet to be reported, along with three other cases of bladder catheter knotting.

PMID: 16898325 MyJurnal

Mesocolic hernia is a rare cause of intestinal obstruction in children. The diagnosis involves a high index of suspicion and prompt intervention to prevent strangulation and a high morbidity. The embryological basis of the condition is of paramount importance to assist the eventual surgical correction.

Congenital esophageal stenosis: report of three cases, literature review, and a proposed classification

PMID: 11315285

The aim of this paper is to report three cases of congenital esophageal stenosis (CES) of different anatomical varieties: (1) stenosis due to tracheobronchial remnants (TBR) involving the lower third of the esophagus; (2) fibromuscular stenosis (FMS) of the middle third; and (3) a membranous diaphragm (MD) involving the lower third. The first two patients were treated by segmental resection of the esophagus and end-to-end anastomosis with dramatic relief of symptoms. The third responded to dilatation. CES is a rare lesion, and about 500 cases are reported in the literature. CES due to TBR and fibromuscular hypertrophy is considered a segmental stenosis, as it involves a length of the esophageal wall, whereas the MD consists of mucosal folds and does not involve its muscular layer. The clinical presentation is varied, and a high index of suspicion is essential to arrive at an early diagnosis. Management depends on the type and severity of the stenosis. Stenosis due to TBR requires segmental resection. FMS may respond to dilatation, but severe degrees of stenosis require segmental excision. MDs usually respond to dilatation or may require endoscopic excision. Segmental stenosis can occur as an isolated lesion or in association with esophageal atresia or stenosis due to a MD. Based on this observation, a classification of CES is proposed.

Rajah S, Ramanujam TM, Anas SR, Jayaram G, Baskaran P, Ganesan J, et al.

Pediatr Surg Int, 1998 Jul;13(5-6):373-6.

PMID: 9639621

Rectal duplications are rare anomalies. Recently, we observed four cases of rectal duplication, each presenting with different clinical features including chronic constipation, a prolapsing rectal "polyp, " a "growth" from the vulva, and acute retention of urine. The variety of clinical presentations may lead to delay in diagnosis and multiple operations.

Singapore Med J, 1997 Apr;38(4):169-71.

PMID: 9269398

A case of desmoplastic small round cell tumour (DSRCT) is presented. This aggressive and rare neoplasm predominantly affects males and is almost exclusively intraabdominal in location. It is unique in that neural, mesenchymal and epithelial markers are co-expressed. Despite multi-modal therapy, the prognosis is extremely poor. The present report details the clinical features and typical pathological findings of DSRCT in an 11-year-old boy, who succumbed to the disease 16 months after diagnosis despite multiple chemotherapeutic regimes.

Malignant transformation of mesenchymal hamartoma of the liver: case report and review of the literature

Ramanujam TM, Ramesh JC, Goh DW, Wong KT, Ariffin WA, Kumar G, et al.

J Pediatr Surg, 1999 Nov;34(11):1684-6.

PMID: 10591570

Here the first case in the literature of both mesenchymal hamartoma and malignant mesenchymoma occurring in a 6-year-old male child, at different times and at different sites in the liver, and also the possible malignant transformation of a mesenchymal hamartoma is reported. The tumor developed from a lesion in the right lobe that was overlooked initially during a left lateral segmentectomy at 18 months of age for a mesenchymal hamartoma. Malignant mesenchymoma is a rare and aggressive tumor. The origin of this tumor is not well understood. There has been no direct support to the hypothesis that malignant mesenchymoma may be the malignant counterpart of mesenchymal hamartoma. The authors provide clinical and histopathologic evidence in our case that suggests the possibility of malignant mesenchymoma arising from a mesenchymal hamartoma. This case emphasizes the need for complete removal of mesenchymal hamartoma and the need for long-term follow-up to detect multifocal lesion or malignant transformation.

Fulltext Open lung biopsy for diffuse parenchymal lung disease in children

Chan PWK, Ramanujam TM, Goh AYT, Lum LCS, Debruyne JA, Chan L

Med J Malaysia, 2003 Dec;58(5):636-40.

PMID: 15190646

An open lung biopsy was performed in 12 children with diffuse parenchymal lung disease. A definitive histopathological diagnosis was obtained from all procedures but determined treatment options in only 10 children (83%). Three (25%) children were ventilated for respiratory failure prior to the procedure. Four (44%) of the other 9 children required ventilatory support after the procedure. Three (25%) children developed post-op pneumothorax that resolved fully with chest tube drainage. There were no deaths as a direct result of the procedure. Open lung biopsy is useful in providing a definitive diagnosis in children with diffuse parenchymal lung disease and determining treatment in the majority of cases. The procedure was well-tolerated with minimal complications.

Fulltext Squamous epitheliotropism of Enterovirus A71 in human epidermis and oral mucosa

Phyu WK, Ong KC, Kong CK, Alizan AK, Ramanujam TM, Wong KT

Sci Rep, 2017 03 21;7:45069.

PMID: 28322333 DOI: 10.1038/srep45069

Hand-foot-and-mouth disease is a self-limiting paediatric infectious disease commonly caused by Enterovirus A71 (Genus: Enterovirus, Family: Picornaviridae). Typical lesions in and around the hands, feet, oral cavity and other places may rarely be complicated by acute flaccid paralysis and acute encephalomyelitis. Although virus is readily cultured from skin vesicles and oral secretions, the cellular target/s of Enterovirus A71 in human skin and oral mucosa are unknown. In Enterovirus A71-infected human skin and oral mucosa organotypic cultures derived from the prepuce and lip biopsies, focal viral antigens and viral RNA were localized to cytoplasm of epidermal and mucosal squamous cells as early as 2 days post-infection. Viral antigens/RNA were associated with cytoplasmic vacuolation and cellular necrosis. Infected primary prepuce epidermal keratinocyte cultures showed cytopathic effects with concomitant detection of viral antigens from 2 days post-infection. Supernatant and/or tissue homogenates from prepuce skin organotypic cultures and primary prepuce keratinocyte cultures showed viral titres consistent with active viral replication. Our data strongly support Enterovirus A71 squamous epitheliotropism in the human epidermis and oral mucosa, and suggest that these organs are important primary and/or secondary viral replication sites that contribute significantly to oral and cutaneous viral shedding resulting in person-to-person transmission, and viraemia, which could lead to neuroinvasion.

Fulltext Transition of Care in Paediatric Surgery: Current practices and perspectives of paediatric surgeons in Malaysia

Tan SK, Sanmugam A, Danaee M, Ramanujam TM, Nallusamy MA, Zahari Z, et al.

Sultan Qaboos Univ Med J, 2019 Nov;19(4):e352-e358.

PMID: 31897319 DOI: 10.18295/squmj.2019.19.04.011

Objectives: Transition of care (TOC) from paediatric to adult care is still at an early stage in Malaysia. This study aimed to explore current practices and perspectives regarding TOC among paediatric surgeons in Malaysia.

Methods: This study was carried out between June and December 2017. All 48 paediatric surgeons currently working in Malaysia were invited to participate in a questionnaire-based survey to assess demographic characteristics and practices and perspectives regarding TOC.

Results: A total of 38 paediatric surgeons participated in the survey (response rate: 79.2%). Overall, 97.4% did not have an organised TOC model in their institution, with most (65.8%) caring for paediatric patients with complex surgical conditions until adulthood. Although the majority (86.8%) felt that care should be transitioned to adult surgeons with appropriate credentials, most surgeons (84.2%) nevertheless preferred to be involved in the management of adolescent patients after transition. However, there was no consensus regarding the most suitable age to begin the transition. Years of experience as a paediatric surgeon and place of practice did not affect overall TOC practice scores (P >0.050 each). The presence of adult comorbidities was considered the most common reason to initiate TOC (81.6%), while the lack of TOC guidelines was perceived to be the greatest barrier (84.2%).

Conclusion: This study provides a better understanding of TOC from the point of view of paediatric surgeons in Malaysia. However, further studies involving other stakeholders (i.e. patients and adult surgeons) are needed to help formulate a suitable and successful TOC model in this setting.

Compound heterozygous mutations in TTC7A cause familial multiple intestinal atresias and severe combined immunodeficiency

Yang W, Lee PP, Thong MK, Ramanujam TM, Shanmugam A, Koh MT, et al.

Clin Genet, 2015 Dec;88(6):542-9.

PMID: 25534311 DOI: 10.1111/cge.12553

Familial multiple intestinal atresias is an autosomal recessive disease with or without combined immunodeficiency. In the last year, several reports have described mutations in the gene TTC7A as causal to the disease in different populations. However, exact correlation between different genotypes and various phenotypes are not clear. In this study, we report identification of novel compound heterozygous mutations in TTC7A gene in a Malay girl with familial multiple intestinal atresias and severe combined immunodeficiency (MIA-SCID) by whole exome sequencing. We found two mutations in TTC7A: one that destroyed a putative splicing acceptor at the junction of intron 17/exon 18 and one that introduced a stop codon that would truncate the last two amino acids of the encoded protein. Reviewing the recent reports on TTC7A mutations reveals correlation between the position and nature of the mutations with patient survival and clinical manifestations. Examination of public databases also suggests carrier status for healthy individuals, making a case for population screening on this gene, especially in populations with suspected frequent founder mutations.
