Acalculous Cholecystopathy - Umbilical Hernia Doctor 9,327 Views • 3 years ago

Patient 65-year-old of age who comes to the medical consultation with pain moderated pain in the right hypochondrium of “several years of evolution” but that it increased one week ago. Also, she shows pain in the umbilical region of “many years of evolution”, that is supported according to the patient - in a constant way.rnTo the examination, we observe an umbilical hernia, apparently divided into two parts. The hernia of the external region measures 25.1 centimeters x 18.0 centimeters and the one that occupies the average region measures 12.0 centimeters x 10.0 centimeters.rnPatient who comes to the medical consultation with moderated pain in the right hypochondrium of one year of evolution but it increased one week ago after eat duck.rnIn the ultrasound scan of the region of the right hypochondrium (patient came having breakfast, that is to say, without previous preparation ) we can observe the liver of 123.8 millimeters high, as well as the porta vein with a diameter of 7.3 millimeters.rnOn having observed the Gallbladder, we think that a side wall is increased in 2.7 mm (hyperechogenic) with several “echogenics points” in the interior (”Biliary Mud”).

The measurements of the gallbladder were: 39.0 x 17.4 millimeters.rnWe can appreciates an echogenic image in the interior that it would make think about stone. The stones are identified as echogenic foci casting acoustic shadowing but but this image did not appear and a re-evaluation is decided in 15 days.

Acalculous cholecystopathy which means disease or condition of the gallbladder without the presence of gallstones. You might also call it functional gallbladder disorder or impaired gallbladder emptying. Some causes may be chronic inflammation, a problem with the smooth muscles of the gallbladder or the muscle of the Sphincter of Oddi being too tight.

REMEMBER:
Umbilical hernia is a congenital malformation, especially common in infants of African descent, and more frequent in boys. An Acquired umbilical hernia directly results from increased intra-abdominal pressure and are most commonly seen in obese individuals.
Presentation:A hernia is present at the site of the umbilicus (commonly called a navel, or belly button) in the newborn; although sometimes quite large, these hernias tend to resolve without any treatment by around the age of 5 years. Obstruction and strangulation of the hernia is rare because the underlying defect in the abdominal wall is larger than in an inguinal hernia of the newborn. The size of the base of the herniated tissued is inversely correlated with risk of strangulation (i.e. narrow base is more likely to strangulate).
Babies are prone to this malformation because of the process during fetal development by which the abdominal organs form outside the abdominal cavity, later returning into it through an opening which will become the umbilicus.
Differential diagnosisrnImportantly this type of hernia must be distinguished from a paraumbilical hernia which occurs in adults and involves a defect in the midline near to the umbilicus, and from omphalocele.

Nasal catheter YAMIK Aleksandr Senin 1,902 Views • 3 years ago

Nasal catheter YAMIK - is a new drug delivery sistem for topical treatment for sinusitis. The introduction of a large volume of the #drugsolution directly into all the paranasal #sinuses - provides new opportunities in the #treatment of #sinusitis! #YamikprocedureNasal catheter YAMIK is a new device for topical sinonasal delivery of medication during rhinosinusitis treatment. Administration of therapeutic solution with YAMIK catheter is called YAMIK procedure. The following features differs YAMIK procedure from all other topical sinonasal delivery techniques: - Medication is delivered into the all paranasal sinuses at one side of nose regardless of their involvement in the inflammatory disease. -Specific position of patient’s head. Patient should lay on the side of of the sinuses, into which solution will be administered. This position is physiological and comfortable for patients, including children and elders. The LHL position was suggested to be the most favorable position for patients to adopt - Therapeutic solutions reliably penetrates into without previous sinus surgery sinuses with natural ostia size. - Paranasal sinuses are filling with medicinal solution by gravity. To accelerate process, it is used small pressure gradient, which created by motion of syringe plunger with amplitude 1 - 2 ml during administration of solution. - It is provided contact of the whole sino-nasal mucosa with medication. - Prolonged time of the contact of sino-nasal mucosa with medicine provides administration of the therapeutically significant dose. Therapeutic solution administered into paranasal sinuses is considered as a STORE. Thanks to affect mucociliary clearance, therapeutic solution is gradually evacuated from sinuses through ostia. Thereby, prolonged nasal irrigation is performed. - Due to extended contact with saline (NaCl 0,9%), viscous colloidal pathological substance filling paranasal sinuses is dissolved. As a result, its viscosity decreases, and substance is removing by mucociliary clearance. Thereby, drainage function of the ostia are returned some time after finish YAMIK method procedure. -The procedure is performing under local anesthesia. - There is no need in active involvement of the patient. Blowing, pronouncing any sounds like “cuckoo”, holding any things and so on is unnecessary. If is performed by a qualified medical professional the procedure is more effective. - Medication contacts only with nasal passages and paranasal sinuses. Thus, it is provided topical drug therapy. - YAMIK procedure is call sinonasal delivery techniques of a therapeutic solution. It differs from nasal techniques, because medicinal solution contacts not only with nasal mucosa, but with mucous membrane of paranasal sinuses. - The only used drug formulation is a solution. - It is possible non-invasive sample extraction from mucosa of paranasal sinuses (for bacteriological, immunological, cytological and a number of others investigation methods).

Electrical Injuries samer kareem 2,229 Views • 3 years ago

Electrical injuries can present with a variety of problems, including cardiac or respiratory arrest, coma, blunt trauma, and severe burns of several types. It is important to establish the type of exposure (high or low voltage), duration of contact, and concurrent trauma. Low-voltage AC injury without loss of consciousness and/or arrest These injuries are exposures of less than 1000V and usually occur in the home or office setting. Typically, children with electrical injuries present after biting or chewing on an electrical cord and suffer oral burns. Adults working on home appliances or electrical circuits can also experience these electrical injuries. Low-voltage AC may result in significant injury if there is prolonged, tetanic muscle contraction. Low-voltage AC injury with loss of consciousness and/or arrest In respiratory arrest or ventricular fibrillation that is not witnessed, an electrical exposure may be difficult to diagnose. All unwitnessed arrests should include this possibility in the differential diagnosis. Query EMS personnel, family, and coworkers about this possibility. Inquire if a scream was heard before the patient’s collapse; this may be due to involuntary contraction of chest wall muscles from electrical current. High-voltage AC injury without loss of consciousness and/or arrest Usually high-voltage injuries do not cause loss of consciousness but instead cause devastating thermal burns. In occupational exposures, details of voltage can be obtained from the local power company. High-voltage AC injury with loss of consciousness and/or arrest This is an unusual presentation of high-voltage AC injuries, which do not often cause loss of consciousness. History may need to come from bystanders or EMS personnel. Direct current (DC) injury These injuries typically cause a single muscle contraction that throws the victim away from the source. They are rarely associated with loss of consciousness unless there is severe head trauma, and victims can often provide their own history. Conducted electrical devices Conducted electrical weapons (CEWs) such as tasers are weapons used by law enforcement that deliver high-voltage current that is neither true AC or DC but is most like a series of low-amplitude DC shocks.[16] They can deliver 50,000 V in a 5-second pulse, with an average current of 2.1 mA.[17] Though they have been temporally associated with deaths in the law enforcement setting, conducted electrical devices (CEDs) in healthy volunteers have been shown to be safe without evidence of delayed arrhythmia or cardiac damage as measured by troponin I.[18, 17] One study of their use in 1201 law enforcement incidents showed mostly superficial puncture wounds from the device probes, and significant injuries only from trauma subsequent to shock, not from the device itself. Of 2 deaths in custody, neither was related to CEW exposure.[19]
