Intentional replantation is an alternative for the treatment of advanced periodontal destruction of the anterior teeth. Systemically healthy three female patient was referred to our clinic with functional complaints. Diagnosis were chronic periodontitis and class III mobility was noted at the mandibular incisors with complete periodontal attachment loss. After phase I periodontal treatment periodontally involved teeth were extracted, endodontic treatment accomplished, the teeth were replanted and fixed to its place with fiber reinforced composite splint. At the end of 2 years tooth was in function with alveolar bone gain. Intentional replantation provided long-term maintenance of patient’s own teeth.

Acute dizziness/vertigo is among the most common causes for visiting the emergency department or primary care physician. Although the majority of these presentations represent an acute peripheral vestibulopathy (APV), lateral medullary, lateral pontine, and inferior cerebellar infarctions can mimic APV very closely. We present an atypical presentation of an aggressive APV and outline how a well-constructed bedside neurotologic evaluation can distinguish central from peripheral vertigo in the acute setting.

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.

Non-small cell lung cancer is one of the leading causes of cancer-related mortality worldwide. Despite recent advances in adjuvant treatments, surgical resection is basis of treatment. With the development of minimally invasive surgery in thoracic surgery, surgeons work on minimally invasive surgery for advanced stages of lung cancer, previously considered non-operable at all or previously considered non-operable with minimally invasive surgery approach. Minimally invasive surgical techniques which are routinely used in the surgical treatment of early-stage lung cancer have started to be treated in more complicated and advanced stages of lung cancer. Bilateral anatomic resections, operations after neoadjuvant chemotherapy, bronchial sleeve lobectomies, double sleeve lobectomies, complementary pneumonectomies, and carinal sleeve resections can be performed by minimally invasive methods. The option of video-assisted surgery should be considered with oncological principles at foreground if patients have acceptable lung and cardiac performance conditions with minimal comorbidities. This study reviews VATS experience in patients with advanced-stage lung cancer worldwide and discusses potential benefits and limitations of using VATS technology to perform thoracic surgery procedures.

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.

Demyelinating peripheral neuropathy has been described in association with tumor necrosis factor (TNF) inhibitors. It is rarely developed after treatment discontinuation. We present the case of a child with juvenile idiopathic arthritis who developed peripheral neuropathy few months after TNF inhibitor withdrawal with clinical worsening of the neurological sequelae while undergoing treatment with abatacept.

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).

Background: Laparoscopic sleeve gastrectomy (LSG) is becoming more popular in the treatment of obesity. LSG is safe with a low morbidity. The complications rarely result in morbidity and even mortality. Leaks are the major complication associated with LSG with a reported prevalence between 1.9% and 2.4%. Objective: To compare surgical intervention and endoscopic stenting for treatment of gastric leakage after sleeve gastrectomy. Patients and method: Our study included 30 patients presented with post sleeve leaks discovered by routine postoperative imaging or during the follow up period. Patients were recruited from October 6th university hospital during the period from August 2017 to August 2019. Patients were divided to the following groups: 1) Endoscopy group: This included 15 patients with post sleeve leakage undergoing endoscopic stent insertion. 2) Surgery group: which included 15 patients with post sleeve leak age undergoing surgical management. This division was random. Results: Our study showed that Endoscopic stenting for management of post sleeve gastrectomy leakage is an effective method with lower morbidity and shorter post-operative hospital stay than surgical management. Some patients may be good candidates for early surgical intervention in type 1 leakage if managed early before dissemination of leakage and before tissues become friable. Complications of stents include stent migration (26%), stent related ulcer (13%) and stricture (13%). while the surgical intervention carries more complications (DVT, chest infection, wound infection and stricture) and longer postoperative hospital stay. Conclusion: endoscopic management of post-sleeve gastrectomy leakage with stenting is recommended because it successfully manages the leaks and avoids invasive procedures with less risk, with shorter hospital stay and early return of function.

In this investigation, solid dispersions were prepared and characterized to improve the solubility and dissolution of poorly water soluble drug Ketoprofen, using glucosamine HCl as a carrier. For the improvement of the solubility and dissolution rate of poorly water soluble drugs different techniques are used such as solubilization, salt formation, particle size reduction and solid dispersion etc, but in the present study, solid dispersions (SDs) of poorly water soluble NSAID Ketoprofen were prepared to improve its solubility and dissolution rate, using solvent evaporation method with drug-carrier ratio of 1:1, 1:2 and 1:3. Our results indicate that all solid dispersions of Ketoprofen and Glucosamine HCl exhibited more enhancements in solubility and dissolution rates than corresponding physical mixtures. The DSC thermograms and X-ray diffraction patterns showed a slight reduction in crystallinity in solid dispersions which were further verified by FT-IR and SEM. It is concluded that solid dispersion is an effective technique for enhancing the solubility and dissolution rate of poorly water-soluble drug Ketoprofen using Glucosamine HCl as a carrier. This amino sugar (Glucosamine HCl) could be used as a novel potential carrier for preparation and formulation of SDs and would have potential commercial benefits.

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
