Q

incubation period of malaria

A

5-15d (vivax/ovale)

The time from the initial malaria infection until symptoms appear (incubation period) typically ranges from: 9 to 14 days for Plasmodium (P.) falciparum. 12 to 18 days for P. vivax and P. ovale. 18 to 40 days for P. malariae.

How soon will a person feel sick after being bitten by an infected mosquito? For most people, symptoms begin 10 days to 4 weeks after infection, although a person may feel ill as early as 7 days or as late as 1 year later. Two kinds of malaria, P. vivax and P. ovale, can occur again (relapsing malaria).

Q

treatment of osteomyelitis

A

Traditionally, antibiotic treatment of osteomyelitis consists of a 4- to 8-week course.

minimum 6 wks

Recommended agents are as follows:

Piperacillin-tazobactam 3.375 g IV q6h or
Ampicillin-sulbactam 3 g IV q6h or
Ticarcillin-clavulanate 3.1 g IV q6h
Patients with penicillin allergy and osteomyelitis from contiguous spread of infection:

( Clindamycin 600 mg IV/PO q6h or metronidazole 500 mg IV/PO q8h) plus ( ciprofloxacin 750 mg PO or 400 mg IV q12h or levofloxacin 750 mg PO daily), or moxifloxacin 400 mg PO daily
If MRSA is suspected:

Add vancomycin 15 mg/kg IV q12h
If a contraindication exists to the use of vancomycin, an alternative anti-MRSA agent such as linezolid, daptomycin, or ceftaroline [6] may be used
Oral therapy following IV treatment for patients with osteomyelitis from contiguous spread of infection:

Amoxicillin-clavulanate 875 mg/125 mg PO q12h or
Ciprofloxacin 750 mg PO q12h plus clindamycin 300-450 mg PO q6h or
Levofloxacin 750 mg PO daily plus clindamycin 300-450 mg PO q6h or

68
Q
  1. La principal complicación de varicela zoster
A

neuraliga post herpetica

69
Q

varcillea replication occurs where

A

in the infected cells’ nucleus

proteins from icosahedral capsid enter cytoplasm with microtubules towards the nucleus with tegument matrix proteins for replication

viral dna makes alfa immediate mrna that codes for alfa protein

alfa protein (immediate) enters nucleus to make more mRNA (beta - delayed early) which reenters cytopalsm tp make beta protein

beta protein reenters nucleas o make more dna and structural mrna (:ATE)

structural mrna makes capsid and spikes

immediate anddelayed early are before DNA replication

it all assembles and buds out of ER vesical, envelpops and then is released to infect other cells and damage them (lytic phase) provoking host immunity or and also nervcells (latent phase) = become circular and stop replicating

can revert back with ehat , hormones or at IC

The human cytomegalovirus (HCMV) can infect a remarkably broad cell range within its host, including parenchymal cells and connective tissue cells of virtually any organ and various hematopoietic cell types.

peripheral blood mononuclear cell (PBMC) = These cells consist of lymphocytes (T cells, B cells, NK cells) and monocytes, whereas erythrocytes and platelets have no nuclei, and neutrophils, basophils, and eosinophils have multi-lobed nuclei.
