Examination in any medical career has never been easy. Even after passing an examination in one’s medical career, one may still harbor nightmares and wake up with fright in the middle of the night. Rigorous examinations in the medical field require a lot of courage and resilience. Unfortunately, many succumb to mental illness.(Copied from article)
The present study examines the gross anatomical features of anomalous lunate sulcus detected incidentally in a cadaveric brain and discusses its clinical importance. The absence of lunate sulcus was carefully studied in a dissected brain specimen. The absence of lunate sulcus was observed unilaterally on the right side of a cadaveric brain specimen. The lunate sulcus was clearly appreciated on the left side whilst on the right side it was absent. The right hemisphere of the cerebellum was also bigger in size as compared to the left. The absence of lunate sulcus is a rare finding, which may be detected incidentally. The anatomical knowledge of the lunate sulcus may be important for neurosurgeons operating on the occipital lobe and the radiologists interpreting CT scan.
The present cadaveric study, describes asymmetrical right cerebral hemisphere and anomalous posterior horn of the right lateral ventricle and discusses its clinical implications. The occipital lobe of right cerebral hemisphere extended more posteriorly as compared to the left and so did the posterior horn of the lateral ventricle, resulting in the thinning of the occipital cortex. Till now, the dimension and volumetric study of the lateral ventricles have been usually performed by MRI and CT scans. A gross anatomical study of such a case, is the rarest of its kind. The abnormal anatomy of the lateral ventricles may be of great academic interest regarding CSF circulation and also important for clinical, radiological and surgical interventions (Fig. 2, Ref 8).

Dua kes dibentangkan di sini, seorang budak lelaki berusia enam tahun dan seorang gadis berusia 15 tahun yang mengalami luka lecuhan tar dan berjaya dirawat dengan menggunakan enema minyak mineral Fleet® dan paraffin tulle Bactigras®, yang mudah didapati di kebanyakan hospital.
Menopause, a cessation of menstrual bleeding, is directly related to serious
illness confined to cardiovascular disease (CVD) such as hypertension and stroke. The oestrogen withdrawal and consumption of high cholesterol diet has
a detrimental effect on cardiovascular function and metabolism in menopausal
women. The present study was aimed to develop the hypertensive rat model in
the ovariectomised Sprague Dawley rats fed with 2% cholesterol diet following a
short term period. Eighteen Sprague-Dawley rats were randomly divided into three
groups; Sham control (sham), ovariectomized control fed with normal diet (Ovx
+N), ovariectomized rats fed with 2% cholesterol diet (Ovx + Cho) for four weeks.
At the end of the study, the food intake and body weight were measured. The
systolic, diastolic and mean blood pressure was determined. OVX+Cho showed
significant increase in physiological changes such as body weight and food intake
compared to Ovx+N group. The significant increase in systolic, diastolic and mean
blood pressure was observed in Ovx+Cho group. Based on the above findings,
it is believed that feeding cholesterol diet for four weeks (short term) results in
significant increase in the blood pressure, food intake and body weight in the
ovariectomised rats.
Abductor pollicis longus (APL) muscle is known to exhibit different variations with respect to its attachments. Various studies have reported the splitting of the APL muscle. Comparative anatomical findings of split insertion of APL is commonly found in chimpanzees, gorillas and gibbons. In the present study, we describe an anomalous APL muscle, which originated from the posterior surface of the shaft of the radius and ulna and traversed a course deep to the extensor retinaculum. Interestingly, immediately after emerging form the deeper aspect of extensor retinaculum, the thin tendon of the APL muscle continued again as a muscular belly in relation to the dorsolateral part of the 1st metacarpal bone, to end as a tendon with its attachment to the base of the proximal phalanx. Such an unusual variation of APL with its attachment into proximal phalanx is a rare finding and may be of importance in altering the mechanics of the thumb during abduction. The clinical significance of such an anatomical variation of APL may be important during reconstructive surgeries involving thumb and also of academic interest.
Introduction: Psoriasis is a chronic, immune mediated, hyperproliferative skin disease that has substantial impact on the sexual functions. This study aimed to determine the prevalence and associated factors of female sexual dysfunction (FSD) in patients with psoriasis.
Methods: A cross-sectional study involving 79 women with psoriasis attending two Dermatology Outpatient Clinics were interviewed and assessed for female sexual dysfunction and severity of psoriasis. The socio-demographic and clinical characteristics of the subjects were compared between the women with and without sexual dysfunction. The subjects were interviewed using Mini International Neuropsychiatric Interview (M.I.N.I.) to exclude any existing psychiatric illness. Sexual dysfunction was assessed using a validated questionnaire on sexual function and the severity of psoriasis was assessed using Psoriasis Area and Severity Index (PASI).
Results: The prevalence of FSD in the patients with psoriasis was 20.3%, with hypoactive sexual desire being the most prevalent problem (44.3%). Sexual dysfunction was associated with older age, menopause, low body mass index, longer duration of marriage and presence of psoriasis in the genital area. Female sexual dysfunction was highly prevalent in patients with psoriasis.
Conclusion: Management of psoriasis should include assessment in patients’ sexual health. Genital area involvement with psoriasis should not be overlooked as it can cause significant psychosexual distress.

BACKGROUND AND AIMS: Parkinson disease (PD) is the second most prevalent neurodegenerative disorder after Alzheimer disease. Besides motor presentations, cognitive impairment is among the other likely complications as the illness progresses. This study aimed to determine the prevalence of cognitive impairment in PD and the factors associated with the cognitive impairment.
MATERIALS AND METHODS: A cross-sectional, descriptive study was conducted on all PD patients at different stages of their illness, in two major tertiary hospitals in Malaysia with their caregivers, over a three month period in 2002. Patients' cognitive functions were tested using the Mini Mental State Examination (MMSE). Important sociodemographic data and relevant clinical information of the patients as well as caregivers' information on income, duration of care-giving, relationship with the patient, and other relevant variables were gathered. Patients' level of functioning was assessed using the Activities of Daily Living (ADL) index. Staging of illness was done based on the Hoehn and Yahr Scale.
RESULTS: Out of 115 eligible patients, 35% were in the 60-69 age group with 57% in stage 2 of illness, A total of 29% of patients experienced various degrees of cognitive impairment , with almost half (47%) in the stage 3 and 4 exhibiting MMSE scores <24. Factors which were significantly associated with impaired cognitions were race, educational level and stage of illness.
CONCLUSION: Cognitive impairment was fairly common in PD and the severity of impairment in cognition and physical functioning increased with the advancement of the illness.
Refeeding syndrome is a potentially fatal clinical condition characterized by severe electrolyte and fluid shifts associated with metabolic abnormalities in severely malnourished or starved patients undergoing oral, enteral or parenteral refeeding. We here present a case of a 50-year-old Indian male with a background of depression and alcoholic liver disease presented with alleged ingestion of a detergent. He subsequently developed an oesophageal stricture resulting in severe malnutrition. He developed refeeding syndrome following commencement of TPN associated with clear biochemical alteration. This was immediately identified and rectified. This case report highlights the prevalence of refeeding syndrome in a typical hospital setting that can easily be overlooked and stresses the importance of early recognition as this is a preventable disorder.
Parkinson's disease (PD) is a multifactorial disorder of the nervous system in which there is a progressive loss of dopaminergic neurons. There is a disturbance in the movement in PD and these include resting tremors, rigidity, bradykinesia or akinesia, disturbance, posture and freezing (motor block). The substantia nigra and other parts of the brain are commonly affected. The disorder could be related to oxidative stress and there is an important role of reactive oxygen species (ROS). A number of herbal products contain active components which are known to possess antioxidant action. Hence, the potential role of herbal products in treating PD cannot be undermined. In the present narrative review, the main aim is to discuss the pathogenesis of PD, define the role of different potential herbal extracts on its pathogenesis which may form the basis of treatment. We also discuss in detail the active chemical compounds present each herb which are effective in the treatment of PD. These herbs include Baicalei, Erythrina velutin, Resveratrol, Peganum Harmal, Curcuma longa (Zingiberaceae), Carthamus tinctorius L. (Safflower), Pueraria lobate, Juglandis Semen (Walnut), Tianma Gouteng Yin (TGY), Lycium barbarum L fruit, Mucuna pruriens (Velvet bean), Chunghyuldan (CHD), Paeoniae Alba Radix. The present review may be beneficial for designing future drugs for effective treatment of PD.
Most breast cancer recurrences occur in the surgical scars or within other quadrants of the same breast. Isolated tumour recurrence occurring in the nipple after breast-conserving surgery and radiotherapy is extremely unusual. The reason for this is unknown, but is speculated to be due to involved surgical margins or an occult involvement of the nipple-areolar complex in a breast cancer of the same breast. We present a case of a 44-year-old Indian woman who had recurrent tumour over her right nipple after an ipsilateral breast-conserving surgery that was followed by adjuvant chemotherapy and radiotherapy. There was no typical malignancy features from the mammogram. However, histopathological study confirmed a malignant growth that infiltrated into the dermis and the underneath breast tissue. Completion mastectomy was then performed and the patient was later treated with Taxane-based chemotherapy. Nipple recurrence after breast-conserving surgery and adjuvant radiotherapy may be confused with other nipple conditions such as Paget's disease of the breast. Comprehensive assessments, which include mammogram and biopsy, have proved that such recurrence do occur, as presented in this case. This warrants a specific management strategy.
Aging is attributed to neuronal loss associated with increased oxidative stress. Vitamin E, and in particular, tocotrienol are potent antioxidants, which have been shown to be neuroprotective. The main aim of the present study was to observe the effect of long term intake of vitamin E in the form of tocotrienol rich fraction (TRF) and refined, bleached, deodorized palm olein (RBDPO) on the brain of experimental rats.
There is an association between reactive oxygen species (ROS) and DNA damage to sperm. Researchers believe that ROS is always present at the sperm's head. The variation of ROS concentration within the area has an impact on the integrity of the DNA.
Chlorella vulgaris (CV), a fresh water alga has been reported to have hypoglycemic effects. However, antioxidant and anti-inflammatory effects of CV in diabetic animals have not been investigated to date. The aim of the present study was to investigate the role of CV in inflammation and oxidative damage in STZ-induced diabetic rats.
At the present time, the differentiation between follicular thyroid carcinoma (FTC) and adenoma can be made only postoperatively and is based on the presence of capsular or vascular invasion. The ability to differentiate preoperatively between the malignant and benign forms of follicular thyroid tumors assumes greater importance in any clinical setting. The PAX8-PPARG translocation has been reported to occur in the majority of FTC. In this study, a group of 60 follicular thyroid neoplasms [18 FTC, 1 Hurthle cell carcinoma (HCC), 24 follicular thyroid adenomas (FTA), 5 Hurthle cell adenomas (HCA), and 12 follicular variants of papillary thyroid carcinomas (FV-PTC)] were analyzed to determine the prevalence of the PAX8-PPARG translocation by fluorescence in situ hybridization. The PAX8-PPARG translocation was detected in 2/18 FTC (11.1%). In addition, 2/18 (11.1%) FTC and 1/5 (20%) HCA showed 3p25 aneusomy only. The frequency of the translocation detected in the study was lower compared to the earlier studies conducted in Western countries. This might be attributed to the ethnic background and geographic location. Detection of either the PAX8-PPARG translocation or the 3p25 aneusomy in FTC indicates that these are independent genetic events. It is hereby concluded that 3p25 aneusomy or PAX8-PPARG translocation may play an important role in the molecular pathogenesis of follicular thyroid tumors.
