1.Comparison of Breastfeeding Practice using Deuterium Oxide Dose to Mother Technique with Maternal Recall Breastfeeding Practice among Mothers in Klang Valley
Malaysian Journal of Health Sciences 2019;17(1):107-113
The assessment of exclusive breastfeeding is important to invest the efforts to promote and support breastfeeding practices. Hence this study was carried out to compare breastfeeding practices among mothers using deuterium dose to mother technique with maternal recall breastfeeding practice. A total of 30 mother-infant pairs from a university hospital and government health clinics in Klang Valley participated and completed the study. Mother-infant pairs were recruited into the study when infants were aged 3 months ± 1 week. Anthropometric measurements (height, weight, waist circumference for mother; length and weight for infant) were carried out. Socio-demographic questionnaire was self-administered while breastfeeding practices were interview administered using maternal recall breastfeeding practice questionnaire (MRBF). This was followed by baseline saliva collection of mother-infant pairs before dose and 6 days after mothers were given 30 ± 0.01g of D2O. The post dose saliva sample of mother-infant pairs were collected 6 times at day 1,2,3,4,13 and 14. The results showed that majority of mothers (57%) were university graduates but majority were stay at home mothers. Meanwhile, mothers had BMI with mean 25 ± 4 kg/m2. The results from MRBF questionnaire showed that all mothers were practising exclusive breastfeeding and their infant never received any water sources other than their breast milk. However, the deuterium dose to mother technique revealed only 3% of mothers were actually practising exclusive breastfeeding. From the isotopic data, the calculated mean intake of milk was 721 ± 243 g/day while the mean non-milk oral intake of 122 ± 22 g/ day. In contrast exclusive breastfeeding infants received only 10 g/day non milk oral intake, demonstrating exclusive breastfeeding practice of mothers. There were different breastfeeding practice reported from mother using deuterium oxide dose to mother technique with maternal recall breastfeeding practice.

PURPOSE: For the synthesis of surfactant protein(SP) peptides and production of next generation artificial pulmonary surfactant(PS), we have isolated SP-B, C from bovine PS, and studied the biochemical properties and amino acid sequences of these protein-peptides. METHODS: Crude surfactant and purified surfactant were isolated from materials extracted from the bovine lung lavage. The hydrophobic SP-B, C were purified by Sephadex LH 60 column chromatography from PS. The purities of SP-B, C were assessed by tricine buffer SDS-polyacrylamide gel electrophoresis and the amino acid sequences of these proteins were determined using Beckman PI-2090. RESULTS: The molecular weights of SP-B, C shown in SDS-polyacrylamide gel electrophoresis were as follows; 15,000-18,000(oligomer) Da for SP-B, 3,500-5,000 Da for SP-C. The amino acid sequences were; FPIPLPYCWL LRTLIKKIQA VIPKGVLAMT VAQCHVVPL LVGGIQQLV IEYSVILLTD TLLGRLPNLV CGLRLRCSG in SP-B, LIPCCPVNIK RLLIVVVVVV LLVVVIVGAL LMGL in SP-C, respectively. These results indicated that the amino acid sequences of bovine SPs were different. CONCLUSION: The SP-B, C were purified from bovine PS, and amino acid sequences of SP-B, C were determined. Further studies are needed for the development and use of next generations of exogenous PS preparation based on synthetic SP-peptides for the treatment of neonatal RDS in the future.

Purpose: The effectiveness of continuous intravenous infusion of fentanyl for pain due to stomatitis, pharyngitis, and esophagitis after hematopoietic stem cell transplantation (HSCT) was investigated. Methods: Subjects included 15 HSCT patients with pain due to mucosal damage. Continuous intravenous infusion of fentanyl was commenced at a dose of 12.5 μg/hour. Pain was controlled through an increase or decrease in volume as needed. Grade of oral mucosal damage, pain scale, and QOL index such as the number of tooth brushing or gargles were measured at the start of administration of fentanyl and at the time of maximum dosage. Results: The median time to start of fentanyl administration was day 7 after transplantation. The median duration of administration was 12 days. The median maximum dosage of fentanyl was 980 (range, 243.8∼3,010) μg/day, and it was reached at a median of day 5 after administration of fentanyl was started. Compared to that observed at the start of fentanyl administration, the grade of oral mucosal damage was significantly increased at the time of maximum administration. However, pain scale was significantly decreased and QOL index was maintained. Conclusion: Continuous intravenous infusion of fentanyl suppressed the increase of pain when mucosal damage increased, maintained QOL, and possibly contributed to selfcare.

Purpose: We evaluated, retrospectively, twenty hips that had undergone revision surgeries because of massive pelvic osteolysis in order to determine the retention rate of acetabular metal shells and polyethylene liner exchanges.. Materials and Methods: We performed liner exchanges for massive osteolysis around stable HG acetabular cups with severe polyethylene wear in twenty-three hips, between June 1996 and May 2003. Clinical and radiological follow-up was available for 20 hips for more than 2 years. In 18 hips, we performed curettage of the granulomatous tissue and tightly packed morselized cancellous allografts into the screw holes or the peripheral rims for the acetabular osteolytic lesions. The mean follow-up period was 3.8 years (range, 2.4 to 9.3 years) and the mean of time from the primary total hip arthroplasties to the component exchanges, was 8.2 years (range, 5.6 to 12.4 years). Results: During the follow-up period, all of the hips were functioning well, and none required any subsequent repeat surgeries. Dislocations occurred three times after the repeat operations in one hip, which was treated successfully with an abduction brace. None of the hips demonstrated a progression of the pre-existing osteolytic lesions or the development of any new osteolytic lesions. At the final follow-up, none of the acetabular components demonstrated any evidence of loosening. Conclusion: Our results demonstrated that isolated liner exchanges and debridement of the granulomatous tissue, with or without bone grafting, can be an effective alternative solution to revision of the cup for massive osteolysis around well-fixed, cementless, acetabular cups in selected patients. Retention of the pre-existing cementless acetabular cup provides less intra-operative and post-operative morbidity. However, in order to determine the longevity of the retained cementless acetabular cups, further long-term studies are necessary.

Fractures of the acetabulum are relatively uncommon. But if fractures of the acetubulum are not accurately evaluated, classified, and reduced anatomically, major sequalae and complications are frequently developed. Because of complicated anatomy, difficulty with surgical exposure, severe comminution, and major associated injuries, the treatment of displaced acetabular fractures between conservative and operative methods is still controversial. We reviewed thirty five cases of displaced acetabular fracture treated operaively from January 1984 to December 1991. The prevalent age was the fourth decade. There was twenty seven cases of associated injuries, twenty two dislocations of the hip. According to the Letournel's classification, the most common fracture type was posterior wall and both column type. The fracture was fixed internally with only screws in thirteen cases and with plate and screws in twenty two cases. Among thirty five patients, five patients were lost in the follow up and another five patients had followed up lesser than one year. The mean duration of follow-up afrer the operation was three years (range, one to eight years). Among twenty five patients who had followed up more than one year, the satisfactory results were achieved in nineteen patients (76%) and the poor results were achieved in three patients (8%). The complications were post-traumatic arthritis, avascular necrosis of femoral head, osteomyelitis in iliac bone, skin necrosis, and heterotopic ossification.

From 1960 through 1965, 39 cases with epileptic seizure caused by the Cystricercus cellulosae were experienced at Kaejong Mental Hospital, Okku-Gun, Chollapukdo province. The present study was carried on at the area of Chollapukdo province where Cysticercus cellulosae cases were frequently reported. Thrity-nine Cystricercus cellulosae cases(35 male and 4 female) with epileptic seizure visited Kaejong Mental Hospital . Okku-Gun, Chollapukdo during the years of 1960-1965 from various Gun(county): Okku-Gun 13, Kimje-Gun 7, and Soonchang-Gun 6. The high incidence was found at the age group of 20-49 years and the distribution of 214 subcutaneous nodules were as follows: Trunk 56.6 percent, upper extremities 26.6 percent, head and neck 9.3 percent, lower extremities 7.5 percent. According to the address of above 39 cases, taenia infestation of the inhabitants in the area was examined by questionaire form. Plain rural area (Maryong-Ri, Okku-Gun); Among 803 persons interviewed, 4.0 percent or 32 complained the output of Taenia segments. The male group showed higher incidence (6.4 percent) than the female(1.5 percent) . The highest incidence was observed at the age group of 30-39 years. Most of the inhabitants of the area had the eating habit of raw beef and pork. Mountainous rural area(Bok-Heung-Myun, Soonchang-Gun); Among 542 persons interviewed, 33 or 6.1 percent complained Taenia infection. The higher incidence was observed in the male group(8.7 percent) than in the female group(3.1 percent) , and also at the age group of 20-49 years. They had eating habit of raw beef and pork. The species of adult worm were identified by morphological examination. Totally 36 adult worms(Taenia saginata 21, T. solium 15) were obtained from 26 cases, and it was experienced that 5 T. solium were eliminated from one person.

Over 100 viruses are known to cause acute viral encephalitis in human. In order to diagnose a viral
central nervous system infection, various laboratory diagnosis methods have been used. In this study,
we examined 220 cerebrospinal fluid samples that were received at the Diagnostic Virology Laboratory
of University Malaya Medical Centre between year 2004 to 2006, by viral isolation, pathogen specific
antibody ELISA, polymerase chain reaction (PCR) and Real-Time PCR. Majority of the samples
were from patients <10 years old. Out of 220 samples, 3 were positive for viral isolation, 27 for
PCR (inclusive for the 3 positive for viral isolation) and 39 for pathogen specific ELISA. The total
positive detection rate of this study was 30%. Herpes virus was the most important aetiologic agent,
responsible for 58% of infection, followed by paramyxovirus (especially measles virus) in 26% of
infection, and 14% by enterovirus. Parvovirus and flavivirus were the other common viruses. Among
the herpes viruses, herpes simplex and cytomegalovirus were the most common.

A 56-year-old man received subtotal gastrectomy for an early gastric carcinoma type IIa+IIc with submucosal invasion. The tumor was made up of mixed papillo-tubular adenocarcinoma and solid carcinomatous portion, the latter comprising approximately four-fifths of the total tumor mass. The solid portion was confined within the submucosa and revealed a mixture of trabecular, compact and pelioid patterns of large polyhedra cells, resembling hepatocellular carcinoma of the liver(Edmondson-Steiner grade 2). Sinusoid-like vascular stroma of classical trabecular hepatocellular carcinoma intervened the tumor cell nests but was not associated with endothelial-cell lining. Immunohistochemical stainings with alpha-fetoprotein and alpha1-antitrypsin gave a strong reactivity in those areas of hepatoid differentiation and in the adjacent minute portion of adenocarcinoma. The findings suggest that a portion of gastric carcinoma may transdifferentiate into cells with hepatoid features along the line of endodermal lineage.
