A case of the leopard (multiple lentigines) syndrome is described. To our knowledge this is the first documented case of this rare but interesting syndrome to be reported in this country.
The use of an autologous ipsilateral internal iliac artery to restore circulation after excision of a ruptured femoral aneurysm in a patient addicted to drugs is described. Autogenous vein graft was not available. The advantages of using the internal iliac artery in this situation are discussed. The use of internal iliac artery graft in this situation has not been previously described in the literature.
Three cases of pseudomembranous colitis seen over the past one year in the Medical Unit, University Hospital, Kuala Lumpur, are reported.
The historical background, spectrum of clinical presentation, diagnosis and treatment of the disease are discussed. Early and wider use of sigmoidoscopy in patients with predisposing factors to pseudomembranous colitis have resulted in increased diagnosis of the condition.
Forty patients with tubal ectopic pregnancies seen over an 18 month period are studied. Epidemiological parameters in the three major groups are compared. The diagnostic problems, signs and symptoms are discussed. Aetiological factors in this area are compared with changing trends in other centres. Pelvic inflammatory disease remains an important cause. The role of conservative approach in surgical treatment of ectopic pregnancy Z5 discussed. The crude incidence rate of ectopic pregnancy in Johore Baru Hospital between January 1978 and June 1979 is 1:358 deliveries.
Submucous fibrosis (SMF) an important precancerous condition occurs almost exclusively in Indians but cases have been reported from several countries throughout the world. The causes of SMF are unknown and there is no known treatment for it. Chillies, tobacco use, vitamin deficiencies and betel quid chewing have been implicated. Ramanathan is of the view that SMF seems to be the Asian version of sideropenic dysphagia. He suggests that SMF appears to be an altered oral mucosa following a prolonged period of chronic deficiency of iron and/or vitamin B complex especially folic acid. This changed state of the oral mucosa subsequently appears to develop more easily a hypersensz"tivity to oral irritants such as spices especially chillies and to the betel quid. He provides biochemical data as well as quotes several studies to support his hypothesis.
The role of fiberoptic bronchoscopy for rapid diagnosis of pulmonary tuberculosis was examined among 74 patients who were suspected of having the disease but had negative sputum smear for acid fast bacilli. Bronchial brushing and washing were routinely performed in all subjects and bronchial biopsy was performed on abnormal mucosa in 7 of them. The diagnosis of pulmonary tuberculosis was confirmed in 44.6% of the patients studied from smear examination, culture, histology or the combination of them. Rapid diagnosis was achieved in 54.5% of the confirmed cases from smear or histology within a few days of examination. Two of the cases had concomitant bronchogenic carcinoma. We conclude that the fiberoptic bronchoscopy is a useful investigation for this group of patients as confirmation of the diagnosis can be made fairly rapidly in a significant proportion of them, hence the treatment can be started confidently.
A retrospective study was made to determine relative incidence of lymphoma subtypes in Malaysia. High grade non-Hodgkin's lymphoma was found to be common. Low grade non-Hodgkin's lymphoma and Hodgkin's disease were relatively rare in this Malaysian series. Non-Hodgkin's lymphoma of B-cell immunophenotype was four times as common as that of T-cell lineage. There was a high incidence of primary extranodal non-Hodgkin's lymphoma.
Imperforate hymen is an uncommon obstructive anomaly of the female reproductive tract, which usually presents with intermittent and cyclical abdominal pain. Although it is usually sporadic, four cases of familial occurrence of imperforate hymen have been reported so far. Imperforate hymen is seldom associated with complications if it is detected early. In view of the possible familial occurrence, it is important to have a high index of suspicion in women who present with imperforate hymen. A detailed menstrual history of other female family members is necessary to enable early detection.
Cutaneous larva migrans is a parasitic skin eruption caused by migration of larvae of various nematodes. Diagnosis of cutaneous larva migrans is currently based on the clinical signs of the creeping eruption. We are investigating a new diagnostic technology called optical coherence tomography (OCT) , which is potentially able to visualize structures in the skin with an 8 microm resolution. This technology could therefore potentially allow rapid, non-invasive, in vivo diagnosis of infestations.
The aim of the present study was to determine the frequency and nature of chromosomal abnormalities involved in patients with the clinical spectrum of ambiguous genitalia (AG), amenorrhea, and Turner phenotype, in order to compare them with those reported elsewhere. The study was conducted in the Cytogenetic Department of Pasteur Institute of Morocco, and it reports on the patients who were recruited between 1996 and 2016. Cytogenetic analysis was performed according to the standard method. Among 1,415 patients, chromosomal abnormalities were identified in 7.13% (48/673) of patients with AG, 17.39% (28/161) of patients with primary amenorrhea (PA), 4% (1/25) of patients with secondary amenorrhea, and 23.20% (129/556) of patients with Turner phenotype. However, Turner syndrome was diagnosed in 0.89% (6/673) of patients with AG, 10.56% (17/161) of patients with PA, and 19.78% (110/556) of patients with Turner phenotype. In addition, Klinefelter syndrome and mixed gonadal dysgenesis were confirmed in 2.97% and 1.93% of patients, respectively, with AG, while, chimerism, trisomy 8, and trisomy 13 were confirmed only in 0.15% each. Trisomy 21 was confirmed in patients with AG and Turner phenotype (0.15% and 0.36%, respectively). Moreover, 5.60% (9/161) of patients with PA have been diagnosed as having sex reversal. Thus, the frequency of chromosomal abnormalities observed in Moroccan patients with PA is comparable to that reported in Tunisia, Turkey, Iran, and Hong Kong. However, the frequency is significantly less than that identified in India, Malaysia, Italy, and Romania.

Core-shell Fe3O4/Au nanostructures were constructed using an advanced method of two-step synthesis from Juglans regia (walnut) green husk extract. Several complementary methods were applied to investigate structural and magnetic properties of the samples. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), electron diffraction, optical, thermogravimetric analysis (TGA), and vibrating sample magnetometer (VSM) were used for nanoparticle characterizations. As shown by HR-TEM, the mean diameter of core-shell Fe3O4/Au nanoparticles synthesized using co-precipitation method was 6.08 ± 1.06 nm. This study shows that the physical and structural properties of core-shell Fe3O4/Au nanoparticles possess intrinsic properties of gold and magnetite. VSM revealed that the core-shell Fe3O4/Au have high saturation magnetization and low coercivity due to the magnetic properties. The core-shell nanoparticles show the inhibitory concentration (IC)50 of 235 μg/ml against a colorectal cancer cell line, HT-29. When tested against non-cancer cells, IC50 was not achieved even up to 500 μg/ml. This study highlights the magnetic properties and anticancer action of core-shell Fe3O4/Au nanoparticles. This compound can be ideal candidate for cancer treatment and other biomedical applications.
