  • Numb chin syndrome, or mental neuropathy is a rare sensory neuropathy characterized by abnormal sensation such as hypoesthesia, paresthesia, or dysesthesia in the chin and lower lip innervated by the mental nerve. Sensory neuropathy of mental nerve is somewhat familiar to dentists because it can occur following nerve damage by trauma or dental treatment such as implant surgery or third molar extraction. It can also result from dental causes including abscess or osteomyelitis. However, it can be the first sign of the systemic disease or malignancy if it is not related to dental causes. In this study, we present the case of a patient who present with hypoesthesia and pain in chin area without other symptoms and is later diagnosed with diffuse large B-cell lymphoma.

  • Heat shock proteins play an important role in plant stress tolerance and are mainly regulated by heat shock transcription factors (Hsfs). In this study, we generated transgenic rice over-expressing OsHsfA7 and carried out morphological observation and stress tolerance assays. Transgenic plants exhibited less, shorter lateral roots and root hair. Under salt treatment, over-expressing OsHsfA7 rice showed alleviative appearance of damage symptoms and higher survival rate, leaf electrical conductivity and malondialdehyde content of transgenic plants were lower than those of wild type plants. Meanwhile, transgenic rice seedlings restored normal growth but wild type plants could not be rescued after drought and re-watering treatment. These findings indicate that over-expression of OsHsfA7 gene can increase tolerance to salt and drought stresses in rice seedlings.

  • Diabetes mellitus is a metabolic disorder characterized by hyperglycemia which results from one or both of decreased insulin secretion and increased insulin resistance. Chronic hyperglycemia causes damage to the eyes, kidneys, nerves, heart and blood vessels. The major goal in treating diabetes mellitus is controlling elevated blood sugars without causing abnormally low levels of blood sugar. A 67-year-old woman was admitted with hyperglycemia, thirst, Lt. leg numbness and both leg weakness. The patient was diagnosed as So-gal(消渴) due to dry ness-heat based on yin-deficiency(陰虛燥熱) through oriental medicine and NIDDM through western medicine. The patient was treated with oriental and western medicines. Specifically herbal medicine(Gamijihwangtang), acupuncture, moxa theraphy were used as well as oral medications. Clinical symptoms improved and hyperglycemia dramatically stablized.

  • Cancer is basically a class of disorder marked by uncontrolled proliferation of cells which have the potential to interfere with different systems of body like digestive, central nervous and circulatory systems by releasing hormones. Tumors that reside only in a specified location and show restricted growth are commonly characterized as benign tumors. When tumor cells grow and effectively spread to other body parts and potentially invade and damage healthy tissues they show various degrees of malignancy. Cancer may be caused by different factors like gene mutations, carcinogens and some medical factors that harm the immune system of the body. Symptoms of cancer are relatively varied and classified according to location, progression pattern and size of tumors as well. Different diagnostic tests are used for evaluation that depends on the type of cancer. Cancer management and chemo protocols also depend on the progression and site where it develops. Cancers like breast, lung, liver, colorectal, prostate, head and neck carcinoma are most commonly diagnosed in Pakistan. This review briefly describes the three most common cancers prevailing in Pakistan and their management evaluation.

  • Dry eye syndrome is a relatively common disease of the tears and ocular surfaces that results in discomfort, visual disturbance, and tear film instability with possible damage to the ocular surfaces. Microvascular submandibular gland (SMG) transfer offers a surgical alternative for a permanent autologous substitution of tears using the basal secretion of a transplanted SMG. Long-term follow-up reveals that this technique is a lasting and effective solution for patients with severe dry eye syndrome. The uncomfortable symptoms were relieved, and the frequency of use of pharmaceutical tear substitutes was reduced. Objective examination showed significant improvement in tear film and some features of ocular surface such as breakup time of tear film and corneal staining. Patients may suffer from obstruction of Wharton's duct or epiphora after surgery. Activation of secretion-related receptors could improve the early hypofunction of the denervated SMG and prevent the duct obstruction. Reduction surgery, partial SMG transplantation, uses of atropine gel or Botulinum toxin A could be the choices of treatment for epiphora.

  • Since the aircraft has a property of moving in the three-dimensional space, it may cause personally and financially critical damage in the case of an accident. Among the causes of aircraft accident, human factor has occupied about 70% of all accidents. Specially, fatigue among human's problems has been studied earlier than any other factor. Fatigue has been the cause of 75% of accidents that are related to human factor. So many studies have been conducted. But the direction of these studies mainly attach importance to the sleep loss and circadian rhythm. Limitation for flight time of ICAO is 8 hours per day, civil airlines in domestic line also adopt the limitation. But this rule is not based on human's performance but compromise between labor and management. The long-haul flight brings about a mental block to pilot. This mental block decreases performance of pilot and loses a lot of important information. So this may cause many accidents. This paper is to offer optimal flight time according to the amount of fatigue due to increasing flight time. The optimal flight time is searched through the field experiment. The experiment has adopted two methods. One is to examine pilot's objective fatigue accumulation rate through the critical fusion frequency, and another is to investigate pilot's subjective fatigue feeling through the fatigue subjective symptoms investigation table.

  • Recent advances in the diagnosis and treatment of inborn errors of metabolism have improved substantially the prognosis of many of these diseases, if diagnosed early enough before irreversible damage occurs. This makes it essential that the practicing pediatrician, especially neonatologists be familliar with the clinical presentations and systematic approaches of these disorders. Characteristic clinical presentations, methods of systematic approach and typing of various disorders is discussed in this review. The signs of neurological dysfunctions of many IEMs manifesting in the neonatal period is very nonspecific, such as poor feeding, poor sucking, apnea or tachypnea, vomiting, hypertonia, hypotonia, seizure, letharginess, consciousness change and coma. Many other non-metabolic severe disorders of neonatal period such as neonatal sepsis and intracerebral hemorrhage share these nonspecific symptoms. Hyperammonemia, metabolic acidosis, ketosis and hyperlatic acidemia are observed in many of these conditions but there are exceptions in which conditions all basal laboratory tests are normal, such as NKH, sulfite oxidase deficiency and peroxisomal disorders. According to the results of basal laboratory tests, IEMs in the neonatal period can be categorized in to 6 types. Grouping of IEMs into 6 types will make confirmatory tests and early emergency treatment more efficient.

  • Hepatitis C virus (HCV) infection is a major medical challenge affecting around 200 million people worldwide. The main site of HCV replication is the hepatocytes of the liver. HCV is a positive enveloped RNA virus from the flaviviridae family. Six major HCV genotypes are implicated in the human infection. In developed countries the children are infected mainly through vertical transmission during deliveries, while in developing countries it is still due to horizontal transmission from adults. Minimal nonspecific and brief symptoms are initially found in approximately 15% of children. Acute and chronic HCV infection is diagnosed through the recognition of HCV RNA. The main objective for treatment of chronic HCV is to convert detected HCV viremia to below the detection limit. Children with chronic HCV infection are usually asymptomatic and rarely develop severe liver damage. Therefore, the benefits from current therapies, pegylated-Interferon plus ribavirin, must be weighed against their adverse effects. This combined treatment offers a 50-90% chance of clearing HCV infection according to several studies and on different HCV genotype. Recent direct acting antiviral (DAA) drugs which are well established for adults have not yet been approved for children and young adults below 18 years. The most important field for the prevention of HCV infection in children would be the prevention of perinatal and parenteral transmission. There are areas of focus for new lines of research in pediatric HCV-related disease that can be addressed in the near future.
