Background: Cyclophosphamide is used for the treatment of malignant and non-malignant diseases, but, it induces oxidative damage and disturbance in the antioxidant defense system. Zinc oxide nanoparticles (ZnO NPs) are used in biomedical applications and consumer products. ZnO-NPs are protected cell membranes against oxidative damage, decrease free radicals and malondialdehyde (MDA) levels, and increase the antioxidant enzyme levels. Objectives: The present aimed to evaluate the ameliorative effect of Zn-O nano-particles on oxidative damage and disturbance in the antioxidant defense system induced by cyclophosphamide in male albino rats. Materials and Methods: 24 adult male albino rats were randomly divided into 4 groups (6 rats of each). Group I (Control group): Received 0.2 ml saline /day i.p. injection for 14 days (day by day), group II, (nZnO group): Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, Group III (CP group): Received CP (20 mg/kg/day) b.w, day by day for 14 days by intraperitoneal injection, Group IV (CP + ZnO NPs group): Received nZnO group: Received nZnO (5 mg/kg/day) b.w., intraperitoneally for 14 days, plus CP (20 mg/kg/day) b.w., day by day for 14 days by intraperitoneal injection. After 24-hr from the last treatment, all animals were anesthetized using light ether. Blood, lungs, and liver samples were taken and prepared for biochemical measurements. Results: Individual treatment of zinc oxide nanoparticles and CP induced liver cytochrome b5, cytochrome C reductase, and glutathione S-transferase (GST) compared to the control group, while CP increased P450. The combination of nZnO and CP prevents the elevation of cytochrome b5, P450, cytochrome C reductase, and GST compared with the CP treated group. Zinc oxide nanoparticles and CP increased liver thiobarbituric acid reactive substances (TBARS). The combination of nZnO and CP prevents the changes in TBARS concentrations compared with the CP. Injection of CP to rats reduced the activities of serum glutathione reductase (GR) and catalase (CAT) as compared with the control group. However, combination treatment of rats with nZnO and CP increased the activities of these enzymes compared with those treated with CP alone. Zinc oxide nanoparticles and CP increased serum and lung TBARS, while decreased glutathione (GSH) concentration compared to the control group, with more pronounced changes by CP. The combination of nZnO and CP prevents the changes in TBARS and GSH concentrations compared with the CP. Conclusion: It can be concluded that CP induced oxidative stress and disturbance in the antioxidant defense system. Treatment of rats with zinc oxide nano-particles and CP together attenuated the oxidative damage and disturbance in the antioxidant defense system induced by CP. So, Patients treated with CP advised to take nZnO to prevent the side effects of chemotherapy. Further studies are necessary to evaluate the amelioration effect nZnO and other nano-particles against oxidative stress induced by CP in different doses and experimental models.

Chronic rhinosinusitis (CRS) is an inflammatory condition involving nasal passages and the paranasal sinuses for 12 weeks or longer [1]. It can be subdivided into three types: CRS with nasal polyposis (CRS with NP), CRS without nasal polyposis (CRS without NP), and Allergic fungal rhinosinusitis (AFRS). To diagnose CRS we require at least two of four of its cardinal signs/symptoms (nasal obstruction, mucopurulent discharge, facial pain/pressure, and decreased sense of smell). In addition, direct visualization or imaging for objective documentation of mucosal inflammation is required. CRS therapy is aimed to reduce its symptoms and improve quality of life as it cannot be cured in most patients. Thus, the goals of its therapy include the following:

Background: Lateral Pancreaticojejunostomy (LPJ) has recognized applications in the management of Chronic Pancreatitis (CP). It is done for patients with severe pain, obstructed and dilated pancreatic duct. Ductal obstruction by stone or stricture causes rise of intraductal pressure and parenchymal ischemia. Surgical decompression of the duct and ductal drainage can achieve best pain relieve and slow the progression of the disease. We want to share our experience of removal of stones and strictures from the pancreatic duct system and drainage of the main pancreatic duct by lateral pancreatojejunostomy (LPJ) for chronic pancreatitis in a teaching institute. Methodology: We studied 32 cases of chronic pancreatitis operated between January 2010 and January 2017 for a period of 7 years. Patients were selected with ultrasonography, CT scan and or Magnetic Resonance Cholangio Pancreatography (MRCP). Dilatation of the main pancreatic duct by at least 7 mm proximal to the obstruction were recruited for operation. We did Roux-Y lateral pancreato-jejunostomy for patients with obstruction of the pancreatic duct due to intraductal stones or strictures. Additional distal pancreatectomy were done in two cases for stones and/or abscess in the tail area. We did one Frey’s operation for stone and fibro-calcification of the head. In all cases ductal drainage was accomplished by LPJ. We studied their post-operative pain control, complications, recurrence and improvement of exocrine and endocrine function of pancreas and mortality during this period. We followed these patients for about 2 years after surgery. Results: We found 27 out of 32 patients got complete remission of the abdominal pain. Their progression of disease also slowed down. Ultrasonic evidence of chronic pancreatitis have improved or resolved. Ductal diameter have decreased. Two had recurrence of stones in the head and in the parenchyma within a year. 2 patients died during this follow-up period. One died three months after LPJ due to massive gangrene of the small intestine distal to LPJ and jejuno-jejunostomy and subsequent short bowel syndrome. Other one died of complications of diabetes and malabsorbtion. Pain free survival is about 84% and recurrence is 6%. Mortality during this follow up period is 6%. Conclusion: We found that surgery, if done early, can have good remission of abdominal pain and can slow the progression of chronic pancreatitis and prevent further stone formation in majority of patients. Patient’s exocrine and endocrine function improves or remain static. Patient with chronic calcific pancreatitis and diabetes are unlikely to have favorable outcome even after decompressive surgery.

Introduction: Disabling hearing loss refers to hearing thresholds superior than 40 dB in the better ear in the adults. The main cause of hearing loss in the elderly is the age-related hearing loss, also called presbycusis. This type of hearing impairment occurs as individuals grow older and is usually sensorineural hearing disorder greater for high-pitched sounds and affects both ears equally. It is estimated that 466 million people worldwide have disabling hearing loss, one third of which are over 65 years old. Objective: To analyze the prevalence of disabling hearing loss in the elderly of Juiz de Fora. Methods: Cross-sectional study with 122 patients. Pure tone audiometry was performed after meticulous physical examination of the external ear. Results: Out of 122 older adults, 85 (69,6%) presented disabling hearing loss. Conclusion: Hearing loss, specially disabling hearing loss, is a frequent condition in the elderly and has a big impact on their quality of life. For that it should be promptly diagnosed so treatment can be initiated.

Related the extremely transmittable abilities of SARS-CoV-2,a harmonious virus to the bat CoV, gets transmitted by three principal processes-- the inhalation of droplets from the SARS-CoV-2 infected person, contacting to the person, and by the surfaces and materials defiled with the virus. Whereupon bat Coronavirus is mostly like the pandemic causing virus SARS-CoV-2, bats are often deliberated and figured out as a possible primary host although no intermediate has not been defined yet in the wherewithal of transmission. The Spike Glycoprotein plays an important role in the case of penetration with the assistance of the ACE2 receptor and the Receptor Binding Domain. In the human body, infiltrating the nucleic acid into host cells, SARS-CoV-2 attacks one cell and one by one into the whole human body; therefore, infected cases are found symptomatic and asymptomatic considering the immune power. Patients with cardiovascular disease or diabetes proceed with their treatment with ACE2 often; therefore, there might be a high chance of getting infected. Whereas the SARS-CoV-2 infects the blood and then lungs, Antigens improvement can be better in order to avoid high-complicated effects. Currently, no vaccination or no accurate cure and treatment has not been defined. An explanation with analysis on SARS-CoV-2 has been performed from the aspect of virology, immunology and molecular biology. Several relevant figures have been included hereby in order to a better understanding of the very concept.

The outbreak of new coronavirus acute respiratory disease (SARS-CoV-2) has been a major global challenge for the scientific community to save humanity. While, the unviability of the vaccine keeps most classes of society, especially African countries, suffer from the healthcare problem. Conventional medicine plants become the alternative method for the therapeutic because it contains valuable bioactive compounds. This brief review devoted the importance of medicinal plants such as Citrus, olive, garlic, ginger, green tea, woad, broad-leaf privet, Japanese torreya, and saffron crocus, by their antiviral effects (anti-SARS coronavirus, anti-HSV, and anti-HIV diseases) and their promising uses as probable boosters of the immune and anti-inflammatory response from SARS-CoV-2 infection. Based on scientific reports, bioactive compounds could inhibit 3-chymotrypsin-like cysteine protease and human protein ACE2, where these facts can be attractive to develop effective drugs. 

Noise is widespread in everyday life and can cause both auditory and non-auditory health impacts. Noise-induced hearing loss remains highly prevalent in occupational settings and is now increasingly caused by exposure to social and environmental noise. Incidence of noise-induced hearing loss (NIHL) has been observed to increase substantially in the recent years. Several advances have taken place in past few years for understanding the molecular basis of NIHL. Our understanding of molecular mechanisms implicated in noise-induced hair-cell and nerve damage has significantly increased. Research in the field of genetics is also advancing at a rapid speed, and several genes linked to NIHL have been discovered. This could help in developing preventive and treatment strategies. This review article focuses on the current research and future trends on auditory effects and consequences of noise pollution in humans, stressing the importance of adequate noise prevention and mitigation strategies as a public health measures.

A 32-year-old G4P301LC3 woman presents to the office for a visit, with a 6-day history of vaginal discharge with an unpleasant odor. On speculum examination, the discharge was green in color and frothy in appearance. Is noticed vulvar erythema, edema, and pruritus, also is noted the characteristic erythematous, punctate epithelial papillae or “strawberry” appearance of the cervix. Vaginal pH was 6.2. Diagnosis of Trichomonas vaginalis is made via wet prep microscopic examination of vaginal swabs.But also, for diagnosis help even the exam with the speculum, concretely “strawberry” appearance of the cervix. The diagnosis is confirmed by culture.Trichomoniasis is a sexually transmitted infection [1,2], that caused by trichomonas vaginalis. Trichomonas vaginalis is a unicellular, anaerobic flagellated protozoan, that inhabits the lower genitourinary tracts of women and men, but that can cause vaginitis. Clinical findings of Trichomonas vaginalis include a profuse discharge with an unpleasant odor. The discharge may be yellow, gray, or green in color and may be frothy in appearance. Vaginal pH is in the 6 to 7.Vulvar erythema, edema, and pruritus can also be noted. The characteristic erythematous, punctate epithelial papillae or “strawberry” appearance of the cervix is apparent in only 10% of cases. Symptoms are usually worse immediately after menses because of the transient increase in vaginal pH at that time. Diagnosis of Trichomonas vaginalis is made via wet prep microscopic examination of vaginal swabs. Other, more sensitive tests are available, including nucleic acid probe study and immunochromatographic capillary flow dipstick technology. The diagnosis can be confirmed when necessary with culture, which is the most sensitive and specific study. Nucleic acid amplification tests (NAATs) have replaced culture as the gold standard. T vaginalis NAATs have been validated in asymptomatic and symptomatic women and are a highly sensitive test [3]. Because the Trichomonas vaginalis is a sexually transmitted infection, both partners should be treated to prevent reinfection. The mainstay of treatment for Trichomonas vaginalis infections is metronidazole. Treatment schemes can be:

Gastric mucosal calcinosis is a very rare pathology of the gastric mucosa. It may develop secondary to several diseases but may also be idiopathic in some cases. In this case, gastric mucosal calcinosis was diagnosed with endoscopic biopsy performed for a patient who presented to our clinic with heartburn and abdominal discomfort. This case involves a very rare gastric pathology, and is being studied here with reference to literature data.

The catamenial pneumothorax is defined as the accumulation of air in the pleural cavity that appears in women infrequently and spontaneously with various clinical presentations. Actually, it is considered as an extremely rare entity with few cases described in the literature, that is the reason why the etiology is still discussed. However, a strong association with thoracic endometriosis syndrome has been found. We want to emphasize how the importance of conducting a diagnosis and having a timely management would improve the quality of life of the patient and give a better prognosis of the disease. Thus, a case report of a 38-year-old female patient who was receiving hormone therapy as a treatment for abdominal endometriosis and repetitive pneumothorax was presented. In the video-assisted thoracoscopy we saw diaphragmatic lesions and pneumothorax during the perioperative and postoperative period. Emphasize the importance of a detailed inspection of each intrathoracic organ during the surgical procedure, we also showed how the intraoperative pleurodesis, the placement of a mesh on the diaphragm and the continuity of the hormonal treatment, seems to be an effective therapy to prevent recurrences and have a better control of the disease. 

Introduction: Prune Belly syndrome is a disease characterized by abdominal muscle defect, bilateral cryptorchidsim and urinary system anomalies (reflux megaureter, hydronephrosis, etc.). Pulmonary, cardiac, and gastrointestinal anomalies may also be present. Management of these rare cases is very important. In this case, the clinical course of a patient with Prune Belly syndrome with megaurethra is presented. Case: The patient from the first gestation and parturition with birth weight of 2500 g and 38 weeks was hospitalized because of the bilateral hydronephrosis. His physical examination revealed undescended testicles and a large penis. The abdominal muscles were not very atrophic. The size of the kidney was small, bilateral hydroureteronephrosis and wide posterior urethra on the ultrasound. Renal function tests were progressively disturbed and the patient underwent cystourethroscopy for diagnostic purposes in terms of posterior urethral valve. A large diverticulum was found in anterior urethra. Prune Belly Syndrome was thought because the orifices were in appearance of reflux. The vesicostomy was applied. After vesicostomy the renal function tests got better but he was hospitalized due to urosepsis two times. In cystoscopic examination, the diverticulum in the urethra was filled with urine and the drainage was very slow. Phimosis was opened with dorsal slit technique. Cutaneous urethrostomy was proximal to the anterior diverticulum. Conclusion: Prune Belly syndrome should be considered in patients with megaurethra and postrenal or renal insufficiency although there are no obvious clinical findings. In Prune Belly cases, via a large penis with obstruction signs, anterior urethral diverticulum should be considered.

Aims: To present a further example showing an efficiency of a modeling method based on the theory of dynamic systems in pharmacokinetics. Study design:The goals of the current study were twofold: to present (1) a further example showing efficiency of a modeling method based on the theory of dynamic systems in pharmacokinetics, an to perform (2) a next step in tutoring the use of computational and modeling tools from the theory of dynamic systems in pharmacokinetics. The data available in the study by Plusquellec et al. published in the October Issue of the Journal Medical Engineering & Physics were used to exemplify the method considered here. For modeling purpose an advanced mathematical modeling method was employed. Modeling was performed using the computer program named CTDB described in the study by Dedík et al. published in September 2007 issue of the Journal Diabetes Research and Clinical Practice. Main outcome: Modeling results revealed that computational and modeling tools from the theory of dynamic systems can be successfully used in the development of a mathematical model of such a complicated process as is a multiple sites discontinuous gastrointestinal absorption.

Ocular disorders encompass a multitude of diseases that are unique in their cause, therapy and degree of severity. Due to distinctive morphology of the eye, efficient ocular drug delivery has proven to be a difficult task. Current treatments of ophthalmological diseases include the usage of both intrusive as well as nonintrusive methods such as injections, eye drops, ointments, gels etc. The current state of the art drug delivery methods are associated with low bioavailability and therefore nanotechnology based drug delivery approached are evolving as for improving the therapeutic index of currently used drugs against variety of ocular disorders. This review highlights the recent developments in nano-formulations for ophthalmic treatment and also offers discussions towards the future prospectus of nano-formulations in the mainstream of ophthalmic diseases.

A 51-year-old women presented with asymptomatic multiple polypoidal nodules over scalp with simultaneous papularnodular skin eruptions involving nose, nasolabial folds and forehead for 40 years duration. Her daughter also noted to be having multiple papularnodular skin eruptions involving nose, nasolabial folds and forehead which raised curiosity of possible familial condition. The punch biopsy of polypoidal nodule indicating histological evidence of spiradenoma was favour in diagnosis of Brook Spienger Syndrome. We report this case as this is a rare clinical entity.

Background: Benzodiazepines are usually prescribed for anxiety and sleep disorders in a long-term fashion that may cause drug dependence. Discontinuation after prolonged administration may lead to withdrawal expression, being anxiety the most predominant sign. It has been described that a context-dependent associative learning process underlies diazepam dependence. Nitric oxide is a crucial player in learning and memory processes, hippocampal transmission, as well as in benzodiazepines withdrawal. Considering that previous results from our laboratory showed an increase in hippocampal functional plasticity only in diazepam dependent rats, the aim of the present investigation is to determine whether diazepam dependence could alter neuronal nitric oxide synthase enzyme (NOS-1) expression within the hippocampus, by using western blot. Results: chronic diazepam-treated animals that developed dependence showed increase in NOS-1 expression in dorsal, but not in ventral hippocampus, while no-dependent or control animals presented similar NOS-1 protein levels. Conclusion: withdrawal from long-term diazepam exposure could be associated to increased nitric oxide neurotransmission within dorsal hippocampus induced by NOS-1 over-expression. This mechanism could underlie the improved hippocampal synaptic transmission previously observed in diazepam withdrawn animals. Confirmatory experiments need to be addressed to determine the mechanisms by which nitric oxide participates in benzodiazepines withdrawal in order find new molecular targets to develop pharmacological tools to prevent the withdrawal syndrome

McArdle’s Disease, or Glycogen Storage Disease Type V, is the result of a deficiency in one of the enzymes responsible for the metabolism of glycogen in the body. Individuals with this disease, lack or produce very small concentrations of the myophosphorylase or glycogen phosphorylase enzyme. McArdle’s disease is a metabolic and recessive genetic disease caused by a mutation on the PYGM gene located on chromosome 11q13. This gene is responsible for the synthesis of the myophosphorylase (or glycogen phosphorylase) enzyme. It is the most common form of muscular glycogenesis. We present here the clinical case of a 35 years old woman diagnosed with McArdle’s disease at the age of 21 after a visit to a Neurologist. It was confirmed that the patient had shown symptoms of this disease at least 10 years before definitive diagnosis: intolerance to exercise, asthenia and muscular weakness. In this report we describe the different signs and symptoms of the disease, as well as the tests performed to confirm the diagnosis by muscle biopsy and genetic analysis. McArdle’s disease is classified as a rare disease and often its diagnosis is delayed due to a lack of knowledge about its symptoms and signs. Our intention is to make, with the description of our clinical case, the information about this disease more available to physicians to prevent future misinterpretations and delayed diagnosis. A medical documentary we have created on “McArdle’s Disease” can be seen in YouTube using the following links: https://youtu.be/HAhoZ7jxz7Q (English version) and https://youtu.be/uZopzSHOl20 (Spanish version).

The strategy of price liberalisation and privatisation had been implemented in Sudan over the last decade, and has had a positive result on government deficit. The investment law approved recently has good statements and rules on the above strategy in particular to pharmacy regulations. Under the pressure of the new privatisation policy, the government introduced radical changes in the pharmacy regulations. To improve the effectiveness of the public pharmacy, resources should be switched towards areas of need, reducing inequalities and promoting better health conditions. Medicines are financed either through cost sharing or full private. The role of the private services is significant. A review of reform of financing medicines in Sudan is given in this study. Also, it highlights the current drug supply system in the public sector, which is currently responsibility of the Central Medical Supplies Public Corporation (CMS). In Sudan, the researchers did not identify any rigorous evaluations or quantitative studies about the impact of drug regulations on the quality of medicines and how to protect public health against counterfeit or low quality medicines, although it is practically possible. However, the regulations must be continually evaluated to ensure the public health is protected against by marketing high quality medicines rather than commercial interests, and the drug companies are held accountable for their conduct.

Segmentectomy may be applied to all segments; superior segmentectomies (lower lobe superior segments for both lungs), lingulectomies (two segments forming lingulas of upper left lobe) and basal segmentectomies (segments other than superior segment for both lungs). In lung segment resections; segmentectomy has an equivalent morbidity, recurrence and survival rate compared to lobectomy, in patients with stage I lung cancer, tumors smaller than 2 cm and within the segmental anatomical limits. Segmentectomy also contributes more to preserving lung function and exercise capacity than lobectomy. In tumor resection; especially in patients with advanced age, insufficient performance or insufficient cardiopulmonary reserve, 2 cm in diameter and acceptable segmental margins may be provided. Limited long-term results show oncological results of robotic approach similar to open and VATS approaches. Robotic approach facilitates surgery with more intuitive movements, greater flexibility and high definition, three-dimensional vision. However, high cost and lack of touch sense are main disadvantages of robotic surgery. New studies are needed to assess quality of life, morbidity, oncological results and cost effectiveness. However, considering development of technology in our age and fact that many surgical robot brands will be released in the near future, it is predicted that disadvantages of robotic surgery will be minimized in the near future. This article reviews experience of segmentectomy in non-small cell lung cancer and discusses benefits and limitations of robotic segmentectomy.

Introduction: Peripherally inserted central venous catheters (PICCs) have been increasingly used as an alternative to conventional central venous catheters for long-term administration of chemotherapy, antibiotics, parenteral nutrition, and hydration in patients with difficult venous access. Traumatic complications to arteries and nerves adjacent to veins selected for PICC placement have been rarely described. Case presentation: We report the case of a PICC placement in the brachial vein of the right upper limb of a 78-year-old woman that resulted in brachial artery pseudoaneurysm and median nerve lesion. Discussion: The pseudoaneurysm was successfully repaired with thrombin injection, but neurological deficits to the hand resulting from nerve injury persisted even four months after the procedure.

Anasarca is generalized swelling of the body following accumulation of fluid in the extracellular compartments. It may result from multiple aetiology mainly of renal, hepatic or cardiovascular origin. The aim of this case report is to highlight the challenges encountered in making diagnosis in a patient with anarsaca. We report a case of a 34 year old transporter who presented with anasarca. He had clinical features and risk factors suggestive of renal, hepatic and cardiovascular disease. However investigations ruled out renal, hepatic or cardiovascular diseases as the aetiology of the anarsaca. The anarsarca was also noted to be unresponsive to diuretics. The diagnosis of the disease causing the anarsaca was therefore a dilemma.
