    Ovarian cancer is the fourth most common cancer among women in Peninsular Malaysia. Epithelial ovarian cancer accounts for 90% of all ovarian tumours. Herein, we present a rapidly growing ovarian tumour in a young female patient, following an uneventful vaginal delivery at home. We discuss on the challenges of making said diagnosis in a post-partum patient who presented with abdomen distension. A 19-yearold lady presented to the Emergency Department three days after spontaneous vaginal delivery at home. Her chief complaint was that of a rapidly progressive abdominal distension. Diagnostic and therapeutic emergency laparotomy were done, revealing a huge cystic ovarian mass. Histopathology reported a high grade, serous ovarian carcinoma. There are multiple causes for abdominal distension in post-partum women, however priority should be given into looking for gynaecological origin, given the changes in hormone. Sudden abdominal distension during post-partum period is rare and a systemic approach in its management is vital. There is, inarguably, a role of diagnostic and therapeutic laparotomy in this.

  2. Fulltext New data on Thelohanellus nikolskii Achmerov, 1955 (Myxosporea, Myxobolidae) a parasite of the common carp (Cyprinus carpio, L.): The actinospore stage, intrapiscine tissue preference and molecular sequence
    Borzák R, Borkhanuddin MH, Cech G, Molnár K, Hallett SL, Székely C
    Int J Parasitol Parasites Wildl, 2021 Aug;15:112-119.

    Thelohanellus nikolskii, Achmerov, 1955 is a well-known myxozoan parasite of the common carp (Cyprinus carpio L.). Infection regularly manifests in numerous macroscopic cysts on the fins of two to three month-old pond-cultured carp fingerlings in July and August. However, a Thelohanellus infection is also common on the scales of two to three year-old common carp in ponds and natural waters in May and June. Based on myxospore morphology and tissue specificity, infection at both sites seems to be caused by the same species, namely T. nikolskii. This presumption was tested with molecular biological methods: SSU rDNA sequences of myxospores from fins of fingerlings and scales of older common carp were analysed and compared with each other and with related species available in GenBank. Sequence data revealed that the spores from the fins and scales represent the same species, T. nikolskii. Our study revealed a dichotomy in both infection site and time in T. nikolskii-infections: the fins of young carp are infected in Summer and Autumn, whereas the scales of older carp are infected in Spring. Myxosporean development of the species is well studied, little is known, however about the actinosporean stage of T. nikolskii. A previous experimental study suggests that aurantiactinomyxon actinospores of this species develop in Tubifex tubifex, Müller, 1774. The description included spore morphology but no genetic sequence data (Székely et al., 1998). We examined >9000 oligochaetes from Lake Balaton and Kis-Balaton Water Reservoire searching for the intraoligochaete developmental stage of myxozoans. Five oligochaete species were examined, Isochaetides michaelseni Lastochin, 1936, Branchiura sowerbyi Beddard, 1892, Nais sp., Müller, 1774, Dero sp. Müller, 1774 and Aelosoma sp. Ehrenberg, 1828. Morphometrics and SSU rDNA sequences were obtained for the released actinospores. Among them, from a single Nais sp., the sequence of an aurantiactinomyxon isolate corresponded to the myxospore sequences of T. nikolskii.

    Idris Z, Nandrajog P, Abdullah JM, Ghani RI, Idris B
    Surg Neurol Int, 2013;4:120.
    PMID: 24083055 DOI: 10.4103/2152-7806.118492
    BACKGROUND: Arachnoid cysts are intraarachnoid benign cystic lesions filled with cerebrospinal fluid and should be treated without incurring further morbidity to the patients.

    CASE DESCRIPTION: The authors present a case of a 68-year-old elderly female with a large right fronto-parieto-temporal arachnoid cyst who has been suffering from mild left hemiparesis for the past 4 years and presented with sudden onset of seizures. The 3 Tesla MR system with diffusion tensor imaging (DTI) and MR tractography of the brain showed a large right fronto-parieto-temporal cystic lesion measuring 7 × 5 × 5 cm with a midline shift of 1 cm, suggestive of an arachnoid cyst with surrounding ipsilateral white matter projection pathways and inferior occipito-frontal fasciculus or inferior longitudinal white matter tracts. The cyst was successfully treated with neuronavigation-guided endoscopic and hodotopical approach to fenestrate the arachnoid cyst into the sylvian cistern, avoiding inadvertent injury to major white matter tracts portrayed by DTI. Postoperatively, a repeated computed tomography (CT) scan of the brain revealed a smaller arachnoid cyst with correction of the midline shift. The patient was weaned off from the ventilator and her hemiplegia improved gradually.

    CONCLUSION: This case report emphasizes the value of neuronavigation-guided endoscopic and hodotopic approach to fenestrate the intra-axial arachnoid cyst.

    MyJurnal
    Background: The tissue specimens used for extraction of DNA in this study were from rodents trapped in four states in Peninsular Malaysia, namely Kedah, Kelantan, Selangor and Johor. Methods: Histological sections of these rodent muscle tissues stained with hematoxylin and eos in showed infection with Sarcocystis spp. Based on these results, the current study was carried out to determine the phylogenetic relationship among the identified Sarcocystis spp. in these rodents.The formalin fixed paraffin embedded (FFPE) rodent muscle blocks were subjected to DNA extraction and followed with semi nested PCR targeting 5’ and 3’ regions of 18S rRNA of Sarcocystis spp. Results: Phylogenetic analysis showed two distinct groups of Sarcocystis spp. among the rodents in Peninsular Malaysia. Most of the identified Sarcocystis spp. were genetically closely related to Sarcocystis rodentifelis and Sarcocystis muris and were also observed to be genetically closely related to Sarcocystis sp. ex Columba livia and Sarcocystis sp. cyst type I ex Anser albifrons. Conclusion: Further classification to confirm these Sarcocystis spp. was not possible as only partial sequences of 18S rRNA was available and this was insufficient for
    optimal differentiation.

  5. Effect of non-steroidal anti-inflammatory drugs on biological properties of Acanthamoeba castellanii belonging to the T4 genotype
    Siddiqui R, Lakhundi S, Iqbal J, Khan NA
    Exp Parasitol, 2016 Jul 2;168:45-50.
    PMID: 27381503 DOI: 10.1016/j.exppara.2016.06.011
    Non-steroidal anti-inflammatory drug, Diclofenac, targeting COX have shown promise in the treatment of Acanthamoeba keratitis, but the underlying mechanisms remain unknown. Using various NSAIDs, Diclofenac sodium, Indomethacin, and Acetaminophen, here we determined the effects of NSAIDs on the biological properties of Acanthamoeba castellanii belonging to the T4 genotype. Using amoebicidal assays, the results revealed that Diclofenac sodium, and Indomethacin affected growth of A. castellanii. In contrast, none of the compounds tested had any effect on the viability of A. castellanii. Importantly, all NSAIDs tested abolished A. castellanii encystation. This is a significant finding as the ability of amoebae to transform into the dormant cyst form presents a significant challenge in the successful treatment of infection. The NSAIDs inhibit production of cyclo-oxegenase, which regulates the synthesis of prostaglandins suggesting that cyclooxygenases (COX-1 and COX-2) and prostaglandins play significant role(s) in Acanthamoeba biology. As NSAIDs are routinely used in the clinical practice, these findings may help design improved preventative strategies and/or of therapeutic value to improve prognosis, when used in combination with other anti-amoebic drugs.

    We report a 35 year-old Iranian female who presented with a sudden onset of left sided hemiparesis associated with temporary loss of consciousness of about 3 minutes. Neurological examination revealed a power of 0/5 over the left upper/lower limbs but reflexes were normal and plantar reflex was downgoing and equivocal. A computed tomography scan was done and it revealed mild bilateral frontal atrophy and a temporal arachnoid cyst which was decidedly an incidental finding and it did not have any relation to the clinical presentation. Electroencephalogram and other laboratory findings were all normal. When the psychiatric team interviewed her, it was revealed that the patient had recently experienced a major stressful event just prior to the hemiparesis. On further interview, the patient had complained of delusions of persecution, delusions of reference and also auditory hallucinations for approximately a year prior to admission. There have been only a spatter of reports of conversion symptoms seen in patients with schizophrenia and this is such a case.

    Malays Fam Physician, 2012;7(2-3):39-41.
    PMID: 25606255 MyJurnal
    A nasopharyngeal (Tornwaldt's) cyst is uncommon. It is often asymptomotic; however it may cause problem if it too big becomes. We present a case of a 24-year-old Malay girl who had been a habitual snorer for years but was unaware of the significance of her problem. Opportunities for an earlier referral and assessment were missed since we were not aware of her history despite previous related but non-specific consultations at our primary healthcare centre. She was referred to us a few years later when her nasopharyngeal cyst became infected. After a course of antibiotics, she proceeded with an endoscopic resection of the nasopharyngeal cyst. A follow-up visit six months later did not reveal a recurrence. This case highlights the importance of a good history for the diagnosis of a nasopharyngeal cyst.

    MyJurnal
    The aim of this retrospective study was to study the clinical patterns of oro-facial infections presented and their management (or trends of management) at the Department of Oral and Maxillofacial Surgery, Dental Faculty, University of Malaya. These included the predisposing factors, presentations and management. This study reviewed the oro-facial infection cases over 15 years. The data was obtained from case note reviews of patients using specially designed proforma. A total number of 409 samples were included in this study. Majority of the patients were generally healthy with about 6.6% having diabetes mellitus. The common presentations were pain (47.4%), pus discharges (16.9%) and limitation of mouth opening (12.5%). The major site was in the submandibular region (18.9%) followed by cheek (13.2%). Most of the infections were from odontogenic source (63.2%). Other sources includes cysts (15.4%) and tumours (6.7%). Incision and drainage were the treatment of choice performed on 57.55% of patients. Monoantimicrobial therapy was the treatment instituted in 20.8% of cases.

    Ann Dent, 2003;10(1):-.
    MyJurnal
    Proliferating Cell Nuclear Antigen (PCNA) is one of the several markers of cellular proliferation. Epithelial proliferations play a significant role in the behaviour of odontogenic lesions. The objective of this study was to describe and compare the distribution of PCNA expression within the epithelial linings of odontogenic cysts. A total of 49 cases of odontogenic cysts consisting of 18 radicular cysts, 16 dentigerous cysts, 15 odontogenic keratocysts (OKCs) was studied. All tissues were processed routinely prior to embedding in paraffin. PCNA immunohistochemical staining was performed on 4 !-tm thick deparaffinized sections mounted on sialinized slides using the peroxidase antiperoxidase method. The distributions of PCNA expression in the cysts linings were noted and comparison was made qualitatively and quantitatively. PCNA labelling index was used for the quantitative assessment. The results showed that PCNA staining was distributed in the basal and supra basal cells for radicular cysts, dentigerous cysts, and OKCs. PCNA labelling index was highest in OKC (22.33±4.07). The high PCNA labelling index in OKC is indicative of high proliferative activity thus supporting previous reports of OKC as the most aggressive type of odontogenic cysts.

    Introduction: Acanthamoeba is an ubiquitous free-living protozoa which causes serious ocular problems. Acanthamoeba keratitis is becoming more prevalent amongst contact lens wearers. The disease can cause loss of vision and blindness if not treated properly. The objective of this research is to study the sensitivity of six Acanthamoeba spp. isolates, of which three were from the clinical isolates (HKL 95, HTH 40 and HS 6) and the remaining three from environmental isolates (TTT 9, TL 3 and SMAL 8) to antimicrobial agents. Methods: The antimicrobial agents chosen for this purpose were polyhexamethylene biguanide (PHMB) and chlorhexidine. Serial dilutions were perfomed for polyhexamethylene biguanide and chlorhexidine. Cyst suspensions from the chosen isolates were exposed to PHMB and chlorhexidine respectively. After 48 hours incubation time at 30°C, each mixture was filtered and filtration membrane was put onto non-nutrient agar laid with Escherichia coli. The agar plates were incubated for three days at 30°C and examined daily until day 14 to detect the presence of Acanthamoeba trophozoites under the inverted microscope. The presence of trophozoites indicated the ineffectiveness of the antimicrobial agents. Results: Both of the antimicrobial agents tested were found to be effective against Acanthamoeba cysts from all the test strains. Polyhexamethylene biguanide gave a minimum cysticidal concentration (MCC) mean value of 2.848 μg/mL while chlorhexidine showed
    MCC mean value at a concentration of 3.988 μg/mL. Conlusion: It can be concluded that the Acanthamoeba cysts were sensitive to polyhexamethylene biguanide and chlorhexidine.

Acanthamoeba keratitis is becoming more prevalent amongst contact lens wearers and it can cause loss of vision and blindness if not treated properly. The objective of this research is to determine the effectiveness of gentamicin against six Acanthamoeba spp. isolates, of which three were clinical isolates (HS 6, HKL 95, HTH 73) and three environmental isolates (SMAL 7, SMAL 8, TTT 9). Cyst suspension from the chosen isolates were exposed to gentamicin. After 48 hours of incubation at temperature of 30°C and 37oC, each mixture was filtered and filtration membrane was put onto non-nutrient agar laid with Escherichia coli. The agar plates were incubated for three days at 30oC and 37oC and the plates were examined daily until day 14 to look for the presence of Acanthamoeba trophozoites under inverted microscope. The presence of trophozoites indicated the ineffectiveness of gentamicin. Gentamicin was found to be effective against Acanthamoeba cysts from all the test strains at both incubation temperatures. The minimum cysticidal concentration (MCC) mean value of gentamicin was 0.193 mg/mL at 30oC and 0.229 mg/mL at 37oC. So, we concluded that gentamicin has cysticidal potential towards Acanthamoeba.

    Acanthamoeba is a free living protozoa that can cause keratitis and granulomatous amoebic encephalitis. Physiological characteristics of this amoeba are found to have a medical importance in which it can be related to the pathogenicity potential of the organism. This study was carried out to investigate the physiological characteristics of survivability during axenization. Six Acanthamoeba strains from three clinical isolates (HSB 1, HKL 48 and HKL 95) and three environmental isolates (PHS 2, PHS 11 and PHS 15) were used in this study. Axenization test was done by treating cysts with hydrochloric acid (3%) and Page saline containing Gentamicin (100 µg/ml). Cysts were then cultured into PYG enrich media, incubated at 30oC and the presence and proliferation of trophozoites of Acanthamoeba were observed. This study showed that PHS 15, HSB 1, HKL 48 and HKL 95 could be axenized but they have poor proliferation rate in PYG enrich media. The result showed that the difference between both clinical and environmental isolates was observed in two strains; PHS 2 and PHS 11. This indicates that there is a possibility that the physiological traits of strains from both isolates are the same and strains from the environment are able to show the pathogenic potential and capable of causing infection to human.

    This study was carried out to observe thermotolerance ability of Acanthamoeba spp. A total of 32 Acanthamoeba spp. isolates obtained from water taps, sinks, swimming pools and sea water were used. Trophozoites of Acanthamoeba spp. were inoculated onto non-nutrient agar (NNA) seeded with heat-killed Escherichia coli using aseptic technique and incubated for 14 days at 30°C to obtain the cyst. The cysts were subcultured onto new agar plates for thermotolerance test at 37°C and 42°C. The plates were observed until 96 hours after incubation for excystation of Acanthamoeba before being declared negative. Overall, 81.25% of samples were able to excyst at 37°C while 37.5% were able to excyst at 42°C. Thermotolerant Acanthamoeba is associated with high pathogenicity potential.

    Providing safe drinking-water to human civilization is indispensable; it is one of the most cost-effective means of reducing the disease burden of diarrhea. Unfortunately, water supply quality monitoring from public water treatment plants (WTPs) is often neglected or taken for granted. To determine the produced water quality, WTPs in Sarawak, Malaysia were assessed for their protozoa removal ability. A self-administered questionnaire based on the regulations in the Drinking-water Standards for New Zealand (DWSNZ) was developed. Optional 10-liter raw water samples were collected from willing WTPs for the detection of protozoan cysts. Routine physical and microbial testing of WTP parameters were also requested for raw water quality overview. Two of the nine assessed WTPs achieved three log credits in the treatment component, one of which belonged to Peninsular Malaysia. No log credits were obtained in the other tested components for any samples. Most of the WTPs employed "Coagulation, Sedimentation, and Filtration" using rapid gravity filters without enhancement (P < 0.05). Giardia cysts were detected in raw water sources used for treatment, and the geographical location was identified as an influencing factor for raw water quality. There is an urgent requirement for active collaboration and holistic approaches to review existing water management policies and interventions. WTPs in Sarawak did not achieve the log credits required to safeguard the microbial quality of the water supplied; however, only Giardia cysts were detected in 10-liter raw water samples despite routine microbial parameter monitoring showing disturbing contamination levels.

    Anaplastic thyroid carcinoma (ATC) is a particularly fearsome form of thyroid cancer due to its extreme aggressiveness and dismal prognosis. Patients with ATC typically present with a rapidly enlarging neck mass with compressive symptoms. We report a case of ATC, mimicking a thyroid abscess; in a 52-year-old Chinese male with one month history of enlarging neck mass. Ultrasound of the neck was suggestive of a thyroid cyst and fine needle aspiration cytology was negative for malignancy. He presented again 2 weeks later with increased swelling and pain suggestive of right neck abscess. An incision and drainage was performed and histopathology result of a proximal isolated enlarged lymph node biopsied revealed metastatic carcinoma. Subsequent right thyroid wedge biopsy finding 1 month later were confirmatory of ATC.

    PMID: 23794081 DOI: 10.1007/s11356-013-1925-1
    An aquatic biomonitoring of Giardia cysts and Cryptosporidium oocysts in river water corresponding to five villages situated in three states in peninsular Malaysia was determined. There were 51.3% (20/39) and 23.1% (9/39) samples positive for Giardia and Cryptosporidium (oo)cysts, respectively. Overall mean concentration between villages for Giardia cysts ranged from 0.10 to 25.80 cysts/l whilst Cryptosporidium oocysts ranged from 0.10 to 0.90 oocysts/l. Detailed results of the river samples from five villages indicated that Kuala Pangsun 100% (9/9), Kemensah 77.8% (7/9), Pos Piah 33.3% (3/9) and Paya Lebar 33.3% (1/3) were contaminated with Giardia cysts whilst Cryptosporidium (oo)cysts were only detected in Kemensah (100 %; 9/9) and Kuala Pangsun (66.6%; 6/9). However, the water samples from Bentong were all negative for these waterborne parasites. Samples were collected from lower point, midpoint and upper point. Midpoint refers to the section of the river where the studied communities are highly populated. Meanwhile, the position of the lower point is at least 2 km southward of the midpoint and upper point is at least 2 km northward of the midpoint. The highest mean concentration for (oo)cysts was found at the lower points [3.15 ± 6.09 (oo)cysts/l], followed by midpoints [0.66 ± 1.10 (oo)cysts/l] and upper points [0.66 ± 0.92 (oo)cysts/l]. The mean concentration of Giardia cysts was highest at Kuala Pangsun (i.e. 5.97 ± 7.0 cysts/l), followed by Kemensah (0.83 ± 0.81 cysts/l), Pos Piah (0.20 ± 0.35 cysts/l) and Paya Lebar (0.10 ± 0.19 cysts/l). On the other hand, the mean concentration of Cryptosporidium oocysts was higher at Kemensah (0.31 ± 0.19 cysts/l) compared to Kuala Pangsun (0.03 ± 0.03cysts/l). All the physical and chemical parameters did not show significant correlation with both protozoa. In future, viability status and molecular characterisation of Giardia and Cryptosporidium should be applied to identify species and genotypes/subgenotypes for better understanding of the epidemiology of these waterborne parasites.

    Spinal extradural arachnoid cysts are rare lesions which typically involve the thoracic spine and are an asymptomatic condition of unknown origin. They may also produce symptoms by compressing the spinal cord or nerve roots. Surgery is the treatment of choice in such lesions, but asymptomatic patients can be managed conservatively. We present a case of symptomatic, probable traumatic origin, spinal arachnoid cyst at our center in Hospital Kuala Lumpur, Malaysia. Magnetic resonance imaging spine showed well-defined, nonenhancing extradural cystic lesion from T5 to T6 vertebrae level compressing spinal cord anteriorly. The patient underwent T5, T6 laminoplasty, T4 partial laminectomy and excision of the cyst. Histologically, the cyst wall comprised of collagen and meningothelial cells. This surgical intervention achieved neurological improvement in terms of motor power in our follow-up of this patient.

    PMID: 28223890
    Cyst formation in the parameatal area is a relatively rare entity and not many cases have been reported in the literature. Two such cases are reported here. First patient was a 46 year old sexually active male who developed a spherical, cystic swelling of 1 cm in size on right lip of external urethral meatus. The second case was a 4 year old boy who presented with asymptomatic recurrent left parameatal swelling. In both the cases, cysts were completely excised and defects were sutured. Histologically, the cyst walls were lined by tall squamous and columnar epithelium. Good cosmetic results were obtained in these two cases without any recurrence at 2 two months follow up.
